Rheumatoid Arthritis

RA Verified · Sep 2026

Rheumatoid arthritis is a systemic autoimmune disease in which inflammation of the synovial lining forms an invasive pannus that erodes cartilage and bone, producing symmetric small-joint arthritis plus extra-articular involvement of the lungs, heart, eyes, nerves and marrow.

The disorder behind symmetric small-joint swelling, morning stiffness that outlasts an hour, anti-CCP, the pannus that erodes bone, and the single most dangerous dosing error in nursing: methotrexate taken daily instead of weekly.

What’s going wrong in the body

The normal physiology, where it fails, and why the body’s compensation backfires.

01 Citrullination — how smoking and gum disease become a joint disease

Rheumatoid arthritis begins with a chemical edit to the body’s own proteins. The enzyme peptidyl arginine deiminase (PAD) converts arginine into citrulline "at sites of tissue damage and inflammation, such as the lungs in smokers" — and the immune response starts at sites such as "the lung, gums, and GI tract." That single sentence is the mechanistic bridge nobody expects: it explains why "cigarette smoking is the strongest environmental risk factor" for a disease of the hands, and why Porphyromonas gingivalis in the gums is on the risk list.

Citrullinated proteins are not recognized as self. Whether the immune system reacts to them depends on genetic permission: the HLA-DRB1 alleles — DRB1 04, DRB1 01 and DRB1 10 — carry the shared epitope, a binding groove that presents citrullinated peptides to T cells. Heritability reflects this, running 40% to 65% for seropositive disease but only 20% for seronegative, with monozygotic twin concordance at 15% against 5% for dizygotic twins.

The disease then runs silently for years. Autoantibodies appear "up to 10 years before the onset of clinical symptoms," during a pre-clinical phase in which "certain immunologic and biochemical abnormalities have been found, but the patients are asymptomatic." By the time a patient notices swollen knuckles, the autoimmunity is a decade old — which reframes what "early treatment" means. Early is early in the symptomatic course, and even then the window is narrow: "initiation within 3 months of RA symptom onset is critical for achieving remission and preventing irreversible joint damage."

Citrullination is the origin of the autoantigen: inflamed lungs in smokers and inflamed gums generate citrullinated proteins that, in a shared-epitope carrier, provoke antibodies years before the joints hurt.

02 Synovitis becomes pannus — and pannus erodes bone

Once synovitis starts, the joint lining fills with immune cells from both arms of the system: innate cells — "monocytes, dendritic cells, mast cells" — and adaptive cells — T-helper 1 (Th1) and T-helper 17 (Th17) cells, B cells, and plasma cells. They release the cytokines that name the modern drugs: tumor necrosis factor (TNF), interleukin-6 (IL-6), and granulocyte-monocyte colony-stimulating factor (GM-CSF). A TNF inhibitor or an IL-6 inhibitor is not a general anti-inflammatory; it is aimed at a molecule on that list.

What makes rheumatoid arthritis destructive rather than merely painful is the pannus. The fibroblast-like synovial cells adopt an invasive phenotype and produce matrix metalloproteinases and ADAMTS, enzymes that digest cartilage. In parallel, "RANKL leads to osteoclast generation resulting in bone erosions, the hallmark feature." That is the same RANKL axis that drives osteoporosis — which is one reason rheumatoid arthritis carries a 60% to 100% increased risk of fracture and is a named secondary cause of osteoporosis.

Erosion is irreversible, and that fact organizes the whole treatment strategy. Cartilage that has been digested and bone that has been eaten at the joint margin do not regenerate; the deformities a patient eventually shows are the visible proof that erosion already happened. This is why the 2021 American College of Rheumatology guideline strongly recommends a treat-to-target approach over usual care, and why a conventional DMARD is started in DMARD-naive patients regardless of disease activity level. Treatment is not aimed at today’s pain — it is aimed at a joint that has not been destroyed yet.

The destructive chain: cytokine-driven synovitis turns fibroblasts into an invasive pannus that digests cartilage, while RANKL-driven osteoclasts erode bone at the joint margin — irreversibly.

03 The hand tells the story — and so do the joints RA never touches

The pattern is as diagnostic as any antibody. Rheumatoid arthritis "typically starts in small peripheral joints, is usually symmetric," involving the metacarpophalangeal and proximal interphalangeal joints, the metatarsophalangeal joints, and commonly the wrists. Two negatives carry as much weight as the positives: "the DIP joints are usually spared," and the spine involvement is cervical only — "the lumbar spine is not involved." The 2010 classification criteria make the same point structurally, by explicitly excluding the distal interphalangeal, first carpometacarpal and first metatarsophalangeal joints — precisely the joints osteoarthritis favours.

The stiffness is the other half of the pattern, and it has a number. Morning stiffness in rheumatoid arthritis — the gelling phenomenon — is "usually experienced after prolonged periods of sleep… or rest and lasts for more than 1 hour," and it eases with movement. Osteoarthritis behaves in the opposite direction: stiffness lasting less than 30 minutes, with pain that "is typically related to activity and resolves with rest." The clinical shorthand that falls out of it: rest helps osteoarthritis and hurts rheumatoid arthritis. The one-line summary worth memorizing: RA involves small joints symmetrically, with prolonged inflammatory morning stiffness; OA involves larger weight-bearing joints asymmetrically, with morning stiffness lasting under 30 minutes.

And here is the finding most students get wrong. The swollen rheumatoid joint has synovial thickening with a "boggy" feel — but "erythema and warmth are usually absent." A joint that is hot, red and exquisitely tender is not a rheumatoid flare; in an immunosuppressed patient it is septic arthritis until proven otherwise. The supporting lab fact makes the same point: a synovial white cell count higher than 25,000/mm³ is rare in rheumatoid arthritis and warrants an infection workup. Teaching the hot-red-joint picture trains people to miss the emergency.

The two arthritides sorted on the findings that actually separate them: which joints, how long the stiffness lasts, what rest does, and whether the x-ray shows erosion or osteophyte.

04 RA is a whole-body disease that happens to hurt in the hands

The same systemic inflammation that erodes joints reaches every organ system, and the nurse "should inform the patient about the signs and symptoms of different organ systems and when to seek medical care." The lungs: interstitial lung disease affects 5% to 16% of patients, is "associated with RA-specific autoantibodies and increased mortality," and is joined by pleuritis, bronchiolitis and increased pulmonary embolism risk. The heart: rheumatoid arthritis "is an independent risk factor for the development of coronary artery disease" and "accelerates" it, with heart failure occurring even without prior ischemic disease, and "cardiac arrhythmia… an important cause of sudden death in RA patients."

Elsewhere: secondary Sjögren syndrome with dry eyes and mouth, in up to 10% of those with pulmonary disease; episcleritis and scleritis, which "have become uncommon with new therapies for RA"; vasculitis of medium and small vessels producing "mononeuritis multiplex or asymmetric polyneuropathy"; anemia of chronic disease with thrombocytosis; Felty syndrome — long-standing seropositive disease with leukopenia and splenomegaly, and worth knowing chiefly because it is "rarely seen today"; non-Hodgkin lymphoma in persistently active disease; and depression in 17% to 39% of patients, which belongs in the assessment rather than in the margins.

Two numbers put the whole disorder in proportion. "Overall mortality in patients with rheumatoid arthritis is three times higher than in [the] general population," driven substantially by cardiovascular disease and interstitial lung disease. And approximately 40% of patients will have functional disability affecting their ability to work within 10 years. Against that, early treatment measurably changes the trajectory: with treatment started within 6 months, patients show "improved functional capacity and decreased disease activity." "RA, if untreated, is a progressive disease with morbidity and increased mortality."

Causes & risk factors

Modifiable factors are teaching targets — the patient can act on them.

Cigarette smoking — "the strongest environmental risk factor," acting by driving citrullination in the lung modifiable Periodontal disease, with Porphyromonas gingivalis named — citrullination in the gums modifiable Obesity — a BMI over 30 kg/m² confers a 30% increase in risk; a Western diet high in calories and low in fiber is also implicated modifiable Occupational exposure to silica, asbestos or textile dust modifiable Older age — peak incidence between 65 and 80 years, not the classically taught 30 to 50 Female sex — 3.6% lifetime risk in women against 1.7% in men Family history — monozygotic twin concordance 15% versus 5% for dizygotic twins HLA-DRB1 shared epitope alleles — DRB1 04, DRB1 01 and DRB1 10; heritability is 40% to 65% for seropositive disease but only 20% for seronegative Seropositive status — high autoantibody titres are a poor-prognosis indicator, and seronegative patients may have less aggressive disease Age under 30 at onset — a poor-prognosis indicator, and by implication the exception rather than the rule Multiple joint involvement or extra-articular manifestations at presentation — both poor-prognosis indicators Geography — incidence is higher in North America and Europe, lower in Asia and South America, with a US and Western European incidence of 40 per 100,000 per year

Signs & symptoms

Each finding tied to the mechanism that produces it — and the triage it calls for.

Symmetric swelling and pain in the MCP, PIP, MTP and wrist joints — with the DIP joints spared early Hold & notify
Why: Synovitis of small peripheral synovial joints. The symmetry and the spared distal interphalangeal joints are what separate this from osteoarthritis at the bedside, and the classification criteria formalize it by excluding the DIP, first carpometacarpal and first metatarsophalangeal joints from scoring.
Morning stiffness lasting more than 1 hour, easing with movement early Expected
Why: The gelling phenomenon, "usually experienced after prolonged periods of sleep… or rest." It is one of the hallmarks of the disease and is the mirror image of osteoarthritis, where stiffness lasts under 30 minutes and pain follows activity. Rest helps osteoarthritis and hurts rheumatoid arthritis.
Swelling that feels boggy — with warmth and redness usually ABSENT Report immediately
Why: Synovial thickening rather than an acute purulent process. This is the finding most often taught wrongly. A joint that is hot, red and exquisitely tender is not a rheumatoid flare — in an immunosuppressed patient it is septic arthritis until proven otherwise, and a synovial white cell count above 25,000/mm³ is rare in rheumatoid arthritis and demands an infection workup.
Insidious onset over weeks to months early Expected
Why: Not a sudden event — which is why the classification criteria require symptom duration of 6 weeks or more, and why patients often present having normalized months of symptoms. The autoimmunity itself has been running for up to a decade already.
Established hand deformities — ulnar drift, swan-neck, boutonnière and Z-thumb late Expected
Why: Ulnar drift from "weakening with laxity or erosion of the extensor carpi ulnaris tendon"; swan-neck from dorsal subluxation of the lateral bands giving PIP hyperextension with DIP hyperflexion; boutonnière from central extensor tendon damage giving the reverse; Z-thumb from interphalangeal hyperextension with MCP flexion. Each is visible proof that erosion has already happened — these are the outcome treatment exists to prevent.
Sudden inability to extend the ring and little fingers late Report immediately
Why: The Vaughan-Jackson deformity — extensor tendon rupture involving the 3rd, 4th and 5th digits — is "considered a surgical emergency." Tenosynovitis has worn the tendons through against eroded bone. This is reported immediately, not at the next clinic visit.
Numbness and tingling in the thumb, index and middle fingers Hold & notify
Why: Carpal tunnel syndrome: "tenosynovitis and tenosynovial effusions of the flexor tendons at the wrist joint can lead to compression of the median nerve." A common and treatable complication that patients often attribute to the arthritis itself.
Rheumatoid nodules over pressure points such as the olecranon and the dorsal finger joints Expected
Why: "The most common extraarticular manifestation." Patients describe them as hard bumps under the skin near joints. They are a marker of systemic disease rather than a local problem, and generally need no intervention themselves.
New or worsening breathlessness or a dry cough Report immediately
Why: Two possibilities that present identically and both matter: interstitial lung disease, affecting 5% to 16% of patients and "associated with RA-specific autoantibodies and increased mortality"; or methotrexate-induced interstitial pneumonitis, which the drug chapter lists among its life-threatening adverse effects. Either way this is evaluated, not observed.
New neck pain, restricted neck movement, arm weakness or gait change Report immediately
Why: Cervical instability from atlantoaxial subluxation — chronic inflammation causes "laxity and stretching of the transverse ligament… and erosion of the bony structures." Symptoms range through pyramidal signs and myelopathy, lower cranial nerve palsies, respiratory failure, vertebral artery dissection, quadriplegia, and death. This is also the pre-procedure safety question, because neck positioning for intubation can injure an unstable cervical spine.
Hoarseness, stridor, or a foreign-body sensation in the larynx Hold & notify
Why: Cricoarytenoid joint involvement — an airway manifestation a nurse can hear. It changes airway management: avoid endotracheal intubation where possible, use the smallest tube if needed, or prefer a face mask or supraglottic device. Temporomandibular involvement similarly limits mouth opening and "may also be asymptomatic."
Fatigue, low-grade fever, appetite loss — and low mood Hold & notify
Why: Systemic cytokine-driven inflammation, plus anemia of chronic disease. Depression affects 17% to 39% of patients and is a manifestation of disease burden, not a character failing — mental health providers are a named part of the care team.
Dry eyes and dry mouth Expected
Why: Secondary Sjögren syndrome, with a prevalence of up to 10% in patients who also have pulmonary disease. It matters perioperatively too — 15% of patients have keratoconjunctivitis, which risks corneal ulceration during prone positioning.

Diagnostics

Test In this disorder Normal
Rheumatoid factor (RF) A positive RF is not a diagnosis. It also appears in Sjögren disease and lupus; in chronic infections — hepatitis C (levels as high as 76%), tuberculosis, subacute infective endocarditis; in sarcoidosis and malignancy; and in up to 4% of young, healthy individuals and older adults. High titres do carry prognostic weight and "probably indicate a poorer prognosis" Antibodies "directed against the Fc portion of IgG," present in 80% to 90% of patients — sensitivity 69%, specificity 85% —
Anti-cyclic citrullinated peptide antibody (anti-CCP / ACPA) This is the specific test, and the better one early: anti-CCP has "similar" sensitivity to RF but "greater specificity than rheumatoid factor for early rheumatoid arthritis." When RF and anti-CCP are both positive, sensitivity and specificity "increase substantially." ACPA positivity also flags the patients at higher risk of interstitial lung disease and increased mortality Present in 70% to 80% of patients — sensitivity 67%, specificity 95% —
ESR and CRP An elevated acute phase reactant scores 1 point in the classification criteria. These are also the labs that track response to treatment — and their normality in a painful hand points away from inflammatory arthritis, since blood tests "are usually normal in osteoarthritis" "Usually elevated" in active disease; anemia of chronic disease and thrombocytosis are common alongside them —
2010 ACR/EULAR classification criteria The excluded joints are a teaching point in themselves: distal interphalangeal, first carpometacarpal and first metatarsophalangeal — precisely the joints osteoarthritis favours. These are classification criteria; diagnosis remains clinical, supported by testing to rule out other diseases 6 or more points classifies RA. Joints: 2–10 large = 1 · 1–3 small = 2 · 4–10 small = 3 · more than 10 including ≥ 1 small = 5. Serology: low-positive RF or ACPA = 2 · high-positive = 3. Elevated ESR or CRP = 1. Symptom duration ≥ 6 weeks = 1 2010 ACR/EULAR criteria, as reported by StatPearls —
Radiographs and MRI MRI findings predict "the future presence of bony erosions" and are useful before radiographic evidence of erosion appears — which is the point, since erosion is irreversible. Contrast with osteoarthritis, which produces marginal osteophytes, subchondral sclerosis and cysts — both narrow the joint space, but only RA erodes and only osteoarthritis grows bone X-ray shows periarticular osteopenia, joint space narrowing, and marginal bony erosions. MRI detects bone marrow edema and synovial thickening —
Synovial fluid analysis A count above 25,000/mm³ is rare in rheumatoid arthritis and warrants an infection workup. This is the laboratory half of the hot-red-joint rule — when the joint looks septic, the fluid usually confirms it White cell count between 1,500 and 25,000/mm³, predominantly polymorphonuclear, with low synovial C3 and C4 despite elevated serum levels —
Pre-treatment screening before any DMARD or biologic Latent tuberculosis must have treatment completed at least 1 month before starting a biologic, and screening precedes TNF inhibitors specifically. This is a hold-the-drug finding, not a paperwork step — and it is one of the clearest places a nurse prevents harm Baseline CBC, liver and renal panels, hepatitis B and C serologies, tuberculosis screening, and pregnancy testing —
Disease-activity measurement Assessment is monthly for moderate-to-severe disease and every 3 to 6 months for low activity or remission. The number is what makes treat-to-target possible: ACR 2021 strongly recommends a treat-to-target approach over usual care, with low disease activity conditionally preferred as the initial goal Scored with a validated instrument — CDAI, DAS28-ESR or DAS28-CRP, SDAI or RAPID3 — at every visit that drives a treatment decision ACR 2021 RA treatment guideline —

Complications

Warning: Irreversible joint destruction and disability Hold & notify
Pannus digests cartilage and RANKL-driven osteoclasts erode bone at the joint margin. Approximately 40% of patients have functional disability affecting their ability to work within 10 years.
Erosion does not reverse, which is why the treatment window is measured in months: "initiation within 3 months of RA symptom onset is critical for achieving remission and preventing irreversible joint damage." Early treatment within 6 months produces "improved functional capacity and decreased disease activity." Vocational rehabilitation and work-site modification are both guideline-recommended precisely because work is what patients lose.
Warning: Cardiovascular disease and interstitial lung disease — the mortality drivers Report immediately
Overall mortality in rheumatoid arthritis is three times higher than in the general population. RA "is an independent risk factor for the development of coronary artery disease," and interstitial lung disease affects 5% to 16% of patients.
The cardiac picture extends beyond coronary disease to heart failure "in the absence of a history of ischemic heart disease," and to arrhythmia, which is "an important cause of sudden death in RA patients." Interstitial lung disease is associated with ACPA positivity and with increased mortality. A new dry cough or breathlessness in an RA patient on methotrexate has two serious explanations — the disease and the drug — and neither is observed.
Warning: Methotrexate toxicity Report immediately
Hepatotoxicity is "the most significant adverse effect"; bone marrow suppression, interstitial pneumonitis and nephrotoxicity are all listed, and "improper daily use of the recommended dose has led to fatal toxicity."
The earliest warning is in the mouth: "mucosal ulceration… may be a sign of impending methotrexate toxicity." Mouth sores are a signal, not a nuisance. Monitoring is CBC, serum creatinine and transaminases weekly for the first 4 weeks, then at least bimonthly. Rescue exists and is worth knowing: leucovorin rescues normal cells, and a single glucarpidase dose "reduces plasma methotrexate concentrations by 97% or more within 15 minutes."
Warning: Serious infection on immunosuppression Report immediately
Biologics and targeted synthetic DMARDs carry a 2 to 3 times increase in serious infections, plus opportunistic infections including tuberculosis and fungal disease, and herpes zoster with JAK inhibitors.
All agents are held during serious active infection and resumed "after the infection has resolved and antimicrobial treatment has been completed." Other class signals to monitor: neutropenia with IL-6 inhibitors, JAK inhibitors and rituximab; raised liver enzymes and cholesterol with IL-6 and JAK inhibitors; thrombosis and a cardiovascular boxed warning with JAK inhibitors; heart failure and demyelinating disease with TNF inhibitors, which are avoided in congestive heart failure and in untreated active hepatitis C.
Caution: Osteoporosis, fracture and the other systemic costs
RA carries a 60% to 100% increased risk of fracture, is a named secondary cause of osteoporosis and a FRAX input, and adds anemia of chronic disease, venous thromboembolism, insulin resistance, and non-Hodgkin lymphoma in persistently active disease.
Glucocorticoids compound the two comorbidities the disease already has — they accelerate bone loss on top of a 60% to 100% baseline fracture excess, and add cardiovascular risk to a disease that independently accelerates coronary disease. Chronic steroid use also means "such patients must be manipulated gently," with thin fragile skin complicating intravenous access and pressure-point care.

Medications for this condition

Why each class is prescribed here — every card links to its full pharmacology page.

Immunosuppressants / Biologics / DMARDs First-line
Immune / Anti-infective · methotrexate

This is the class that changes the disease rather than the symptoms — DMARDs "modulate immune mechanisms to suppress inflammation, prevent joint destruction, and maintain remission," so they change the course of the disease rather than merely managing symptoms. Methotrexate is the anchor, and the 2021 ACR guideline says so at its highest strength: "Methotrexate monotherapy is strongly recommended" over hydroxychloroquine or sulfasalazine, and over biologic or targeted-synthetic monotherapy, for DMARD-naive patients with moderate-to-high disease activity. The dosing fact that must never be blurred: methotrexate for RA is WEEKLY — sources give starting ranges of 7.5 to 15 mg once weekly titrated toward 20 to 25 mg weekly, and "improper daily use of the recommended dose has led to fatal toxicity." Folate supplementation of 1 mg/day or 5 to 7 mg weekly "should be considered for all patients to prevent bone marrow suppression." Contraindications are absolute in pregnancy and breastfeeding, in chronic liver disease, cirrhosis, alcoholic hepatitis or active alcohol use disorder, in blood dyscrasias and active infection, with dose reduction below a GFR of 60 and avoidance below 15. Monitor CBC, creatinine and transaminases weekly for 4 weeks then at least bimonthly, and treat mouth ulcers as a toxicity signal. When methotrexate at maximum tolerated dose is not enough, ACR 2021 says "addition of a bDMARD or tsDMARD is conditionally recommended over triple therapy" — TNF inhibitors, IL-6 inhibitors, abatacept, rituximab or a JAK inhibitor. Before any biologic: screen for hepatitis B and C and tuberculosis, with latent TB treated for at least 1 month first, and never give a live vaccine. When the patient reaches target for 6 months, ACR 2021 gives a three-step hierarchy, and the first step is to change nothing: (1) continuing all DMARDs at the current dose is conditionally recommended over dose reduction; (2) if a reduction is undertaken, dose reduction is conditionally recommended over gradual discontinuation; and (3) gradual discontinuation over abrupt discontinuation. Reaching target is not itself a trigger to taper.
Corticosteroids
Endocrine · prednisone

A bridge, and the guideline is emphatic that it should end. The sourced uses are narrow: bridge therapy for "a new patient with very active RA," short courses for mild flares, and intra-articular injection for a single-joint flare, with about 50% of patients requiring low-dose prednisone at some point. But ACR 2021 states it at strong strength: "Initiation of a csDMARD WITHOUT longer-term (≥3 months) glucocorticoids is STRONGLY recommended over initiation of a csDMARD with longer-term glucocorticoids," because "the toxicity associated with glucocorticoids was judged to outweigh potential benefits." Teach the bridge as a bridge, with a planned end date — not as routine chronic therapy. The disorder-specific reason is that steroids compound exactly the two comorbidities RA already carries: a 60% to 100% increased fracture risk, and independently accelerated coronary artery disease. One practical rule belongs at the bedside: perioperative glucocorticoid coverage is required above a prednisolone dose of 10 mg/day — hydrocortisone 50 mg IV before incision then 25 mg IV every 8 hours for a minor procedure, 100 mg IV before incision with an infusion for a major one.
NSAIDs
Musculoskeletal · ibuprofen

Symptom relief only — they "do not have any disease-modifying effects." Meloxicam, naproxen, celecoxib and nabumetone are named, and the class carries a cardiovascular black-box warning, which bites harder here because rheumatoid arthritis is itself an independent cardiovascular risk factor. The disorder-specific interaction is the one most often forgotten: NSAIDs "increase the risk of MTX toxicity" — and methotrexate is the anchor drug nearly every RA patient is taking. Trimethoprim-sulfamethoxazole and proton pump inhibitors raise methotrexate toxicity the same way, and all three are commonly co-prescribed. Note also what the current guideline says about NSAIDs in RA: nothing at all — its "recommendations are limited to DMARDs approved by the US FDA for treatment of RA" (ACR 2021). Present them as symptomatic adjuncts with the methotrexate interaction front and centre; the gastrointestinal and renal cautions belong to the class page.

Beyond medications

  • Exercise — the only STRONG recommendation in the 2022 ACR rehabilitation guideline. "Consistent engagement in exercise is strongly recommended over no exercise" (moderate certainty). Conditionally recommended over no exercise: aerobic exercise, aquatic exercise, resistance exercise, and mind-body exercise including yoga, Tai Chi and qigong. The strength of that recommendation is the answer to a patient who believes activity will damage their joints.
  • Rehabilitation and self-management, each conditionally recommended: comprehensive occupational therapy; comprehensive physical therapy; hand therapy exercises for hand involvement; joint protection techniques; activity pacing, energy conservation, activity modification and fatigue management; and assistive devices. Occupational therapy for the hand specifically covers "training of motor function, instructions for joint protection, the usage of assistive devices such as therapy gloves, splints, hand or wrists orthoses, electric jar, and can openers." Pacing and energy conservation are guideline-recommended interventions, not folk advice.
  • Splinting, orthoses and bracing, conditionally recommended by site: splinting, orthoses and/or compression for hand and wrist involvement or deformity; bracing, orthoses and/or taping for foot and ankle involvement; and bracing and/or orthoses for knee involvement.
  • Work is a treatment target. For patients employed or wanting to be, vocational rehabilitation is conditionally recommended, and work-site evaluations and modifications are conditionally recommended over none. This matters because about 40% of patients develop work-limiting disability within 10 years — the intervention is aimed at the outcome the disease actually takes.
  • Diet — and the sourced answer to "what should I cut out?" is nothing. A Mediterranean-style diet is conditionally recommended over no formally defined diet; any other formally defined diet is conditionally recommended AGAINST; and following established dietary recommendations without dietary supplements is conditionally recommended over adding supplements. Elimination diets and supplement regimens are not supported.
  • Thermal modalities, massage and acupuncture are conditionally recommended; electrotherapy is conditionally recommended AGAINST. Note the wording carefully: the guideline recommends "thermal modalities" as a single undifferentiated category on very low certainty evidence. It does not separate heat from cold or assign either to a particular situation, so teach heat or cold, whichever the patient finds helpful, rather than a decision rule — StatPearls lists "thermo-therapy either heat or cold."
  • Perioperative and procedural safety — the review-level guidance a nurse acts on. Ask about neck pain and limited neck movement before any procedure involving airway management or positioning: the standard sniffing position "involves head hyperextension and neck flexion, and may thus exacerbate AAS and cause neurological injury," with quadriplegia and sudden death among the rare complications. "Preoperative plain radiography of the cervical spine has been recommended for all RA patients," though the review itself notes "no evidence-based guidelines or consensus have emerged"; MRI is superior where neurological signs are present, and awake fiberoptic intubation is recommended with cervical instability, limited neck motion or restricted mouth opening. Airway assessment includes the Mallampati test, because temporomandibular involvement limits mouth opening and "may also be asymptomatic." On medications: conventional DMARDs can generally be continued for elective joint surgery, but "all current biological and targeted synthetic DMARDs should be stopped prior to surgery," with tofacitinib withheld at least 7 days — plus strict aseptic technique and antibiotic prophylaxis, and eye protection during prone positioning.

Nursing considerations

The RN-specific layer — each action paired with the reason it matters.

Assessment & monitoring
Assess the joint pattern deliberately: which joints, symmetric or not, and how long the morning stiffness lasts — and check whether the DIP joints are involved.
Why: Symmetric MCP, PIP, MTP and wrist involvement with spared DIP joints and stiffness over 1 hour that eases with movement is rheumatoid arthritis; DIP nodes with stiffness under 30 minutes and pain that follows activity and resolves with rest is osteoarthritis. The pattern is as informative as the antibody.
Treat a single hot, red, exquisitely tender joint as septic arthritis until proven otherwise — not as a flare.
Why: In rheumatoid arthritis the swollen joint feels "boggy," and "erythema and warmth are usually absent." A synovial white cell count above 25,000/mm³ is rare in RA and warrants an infection workup. These patients are immunosuppressed, so the stakes of calling it a flare are high.
Monitor methotrexate labs on schedule: CBC, serum creatinine and transaminases weekly for the first 4 weeks, then at least bimonthly.
Why: Hepatotoxicity is "the most significant adverse effect," bone marrow suppression and nephrotoxicity are both listed, and the labs are the only early warning for two of the three. A missed monitoring visit is a missed chance to catch toxicity before it is symptomatic.
Ask about mouth ulcers at every methotrexate review and treat a positive answer as urgent.
Why: "Mucosal ulceration… may be a sign of impending methotrexate toxicity." Patients reliably dismiss mouth sores as a minor irritation, so the question has to be asked rather than waited for.
Screen the systems the disease attacks: new breathlessness or dry cough, chest symptoms, dry eyes and mouth, numbness or weakness, and mood.
Why: The nurse’s stated role is to "inform the patient about the signs and symptoms of different organ systems and when to seek medical care." Interstitial lung disease affects 5% to 16% and carries increased mortality; RA independently accelerates coronary disease; and depression affects 17% to 39% of patients and belongs in the assessment.
Ask about neck pain and limited neck movement before any procedure involving positioning or airway management, and flag a positive answer.
Why: The sniffing position for intubation "involves head hyperextension and neck flexion, and may thus exacerbate AAS and cause neurological injury." Preoperative cervical radiography "has been recommended for all RA patients," and awake fiberoptic intubation is recommended where instability or restricted motion exists.
Interventions & safety
Verify methotrexate frequency at every single encounter — weekly, and confirm it with teach-back.
Why: "Improper daily use of the recommended dose has led to fatal toxicity." The starting dose varies by source between 7.5 and 15 mg, but the weekly frequency is identical in every source and is non-negotiable. Verify what day of the week the patient takes it, and check that only one week of tablets is dispensed at a time where possible.
Confirm hepatitis B and C serology and tuberculosis screening are complete before a biologic is started — and that latent tuberculosis has been treated for at least 1 month.
Why: Biologics raise serious infections 2 to 3 fold and reactivate latent tuberculosis. The screening is a hold-the-drug requirement, not a formality, and it is one of the clearest places a nurse prevents a catastrophe.
Check the vaccine record and ensure no live vaccine is given to a patient on a biologic, a targeted synthetic DMARD or high-dose methotrexate.
Why: Live vaccines are "contraindicated during therapy with biologic DMARDs, targeted synthetic DMARDs, and high-dose methotrexate." The recommended non-live vaccines to give instead are pneumococcus, hepatitis, influenza, HPV, herpes zoster and COVID-19.
Hold all DMARDs and biologics during serious active infection, and resume only after the infection resolves and antimicrobials are complete.
Why: The sourced rule is explicit. Continuing immunosuppression through a serious infection removes the response the patient needs, and the decision to restart is deliberate rather than automatic.
Review the medication list specifically for NSAIDs, trimethoprim-sulfamethoxazole and proton pump inhibitors in any patient on methotrexate.
Why: All three raise methotrexate toxicity — and NSAIDs are commonly taken for the very disease methotrexate is treating, often bought over the counter without being mentioned. This interaction is the most clinically relevant NSAID caution in rheumatoid arthritis.
Treat a patient doing well as a reason to leave the regimen alone — not as a cue to taper — and handle steroids as a bridge with a planned end.
Why: For patients at target for at least 6 months, ACR 2021 ranks three options in order: continuing all DMARDs at the current dose is conditionally recommended over dose reduction, dose reduction over gradual discontinuation, and gradual discontinuation over abrupt. So the default at target is continuation; a reduction, if chosen, is stepwise and never a stop. Separately, the guideline strongly recommends starting a conventional DMARD without glucocorticoids lasting 3 months or more.
Patient teaching
Teach methotrexate as a weekly medication and confirm understanding by teach-back — and add that folic acid is taken as prescribed, alcohol is avoided, and dual contraception is used.
Why: The sourced teaching script: "avoid alcohol because of the increased risk of liver disease"; "practice any 2 forms of birth control"; the dose is "once weekly," and "improper daily use of the recommended dose has led to fatal toxicity"; "call 911 immediately" for signs of infection, "coughing, wheezing, or shortness of breath," or "unusual bleeding"; and close follow-up. Methotrexate is contraindicated in pregnancy for non-neoplastic disease because of embryo-fetal toxicity including fetal death.
Teach the report-immediately list by name: sudden inability to extend the ring and little fingers; a single hot red painful joint; new breathlessness or dry cough; mouth sores, unusual bruising or bleeding, or fever; and new neck pain, arm weakness or gait change.
Why: Each maps to a specific emergency — extensor tendon rupture is "considered a surgical emergency," a hot red joint is septic arthritis, a dry cough is interstitial lung disease or methotrexate pneumonitis, mouth sores signal impending methotrexate toxicity, and neck symptoms signal cervical instability.
Answer "should I rest?" with the guideline: consistent exercise is strongly recommended over no exercise, including aerobic, aquatic, resistance and mind-body forms.
Why: It is the only strong recommendation in the entire ACR 2022 rehabilitation guideline. Patients reasonably assume that a joint disease means protecting the joints by staying still, and the evidence says the opposite — while rest is what helps osteoarthritis, not rheumatoid arthritis.
Teach pacing, energy conservation and joint protection as named interventions, with occupational therapy referral and assistive devices where the hands are involved.
Why: "Use of activity pacing, energy conservation, activity modification, and/or fatigue management is conditionally recommended," as are joint protection techniques and assistive devices. For thermal modalities, teach heat or cold as the patient finds helpful — the guideline recommends the category without separating them or assigning either to a situation.
Repeat the core messages at every visit: smoking cessation, weight management, vaccinations, healthy diet, and disease education — and steer diet toward Mediterranean-style without supplements.
Why: These are the sourced repeat-at-every-visit list. Smoking is "the strongest environmental risk factor," obesity above a BMI of 30 adds 30% to risk, and the guideline conditionally recommends against any formally defined diet other than Mediterranean-style and against adding dietary supplements.
Raise work, mood and body image directly, and refer to vocational rehabilitation, work-site assessment and mental health support.
Why: About 40% of patients develop work-limiting disability within 10 years, and vocational rehabilitation and work-site modification are both guideline-recommended. Depression affects 17% to 39%, and mental health providers are a named part of the interprofessional team, since many patients "become depressed and need a mental health nurse and counselor to cope with their disease."

How a real nurse thinks

The clinical-judgment loop, worked for a typical presentation — reasoning, not reference.

  1. 1
    Recognize cues

    The cue that outranks everything else is in the medication history, not the vital signs: methotrexate 15 mg taken DAILY for 7 weeks when it was prescribed WEEKLY. The drug chapter’s warning is exact — "improper daily use of the recommended dose has led to fatal toxicity." Everything else follows from it. Mucosal ulceration is not a coincidence: it "may be a sign of impending methotrexate toxicity." The pancytopenia is bone marrow suppression, the bruising is the thrombocytopenia made visible, the ALT of 214 is hepatotoxicity — "the most significant adverse effect" — and the creatinine has nearly doubled. The fever at 38.1 °C in a patient with a white count of 1.6 is an infection risk, not a flare. And two aggravating factors are sitting in the same history: self-purchased ibuprofen, which "increase[s] the risk of MTX toxicity," and folic acid taken only "sometimes," when it "should be considered for all patients to prevent bone marrow suppression."

  2. 2
    Analyze cues

    This is not a rheumatoid flare and it is not a coincidental illness — it is cumulative methotrexate overdose, delivered at roughly seven times the intended weekly exposure for seven weeks. The organ pattern matches the drug exactly: mucosa, marrow, liver and kidney are the four systems the chapter names, and all four are involved. Two things must not be misread. First, the fever: with a white count of 1.6 ×10⁹/L she is neutropenic, so fever here is a potential serious infection, not disease activity. Second, if she develops a dry cough or breathlessness over the coming days, methotrexate-induced interstitial pneumonitis is on the list alongside the interstitial lung disease that rheumatoid arthritis itself causes in 5% to 16% of patients — and the drug chapter lists pneumonitis among its life-threatening effects. Her renal impairment compounds everything, since methotrexate is dose-reduced below a GFR of 60 and avoided below 15.

  3. 3
    Prioritize

    Stop the methotrexate now — that is the first action and it needs no negotiation. Stop the ibuprofen too, because it is actively raising methotrexate levels. Second, escalate urgently: this patient needs assessment for leucovorin rescue, and the team should know that glucarpidase "reduces plasma methotrexate concentrations by 97% or more within 15 minutes" if levels warrant it. Third, treat her as neutropenic with a fever — cultures and urgent medical review, because a white count of 1.6 with a temperature of 38.1 °C is a sepsis question. Fourth, support the mucositis enough that she can take fluids, since she is already struggling to drink with a creatinine that has doubled. The teaching conversation matters enormously, but it happens after she is safe — and it happens without blame, because this is a dispensing and education failure, not a patient failure.

  4. 4
    Generate solutions

    Anticipate immediate discontinuation of methotrexate and ibuprofen, a methotrexate level, and leucovorin rescue with glucarpidase held in reserve. Anticipate blood cultures and urgent evaluation for neutropenic sepsis, intravenous fluids for the renal impairment and her poor oral intake, and repeat CBC, creatinine and transaminases — the same three tests the monitoring schedule specifies weekly for the first 4 weeks, which in this case were never going to be reassuring. Expect the prednisone to continue rather than stop abruptly. Plan the safety net for discharge: a teach-back-confirmed weekly schedule with a named day of the week, folic acid taken reliably, a dispensing arrangement that does not put a month of tablets in the house at once, and a clear instruction that over-the-counter painkillers go through the team first.

  5. 5
    Take action

    Hold the drug, remove the ibuprofen, and call. The SBAR: "68-year-old woman, 7 weeks into methotrexate 15 mg prescribed weekly for seropositive RA. She has been taking it DAILY for 7 weeks and has also been self-medicating with ibuprofen. She has extensive oral ulceration, unexplained bruising, and a temperature of 38.1. Bloods show WBC 1.6, platelets 68, Hb 9.2, ALT 214 and creatinine 1.6 from a baseline of 0.9. I have stopped both drugs. Requesting urgent review for methotrexate toxicity with leucovorin rescue, and she needs a neutropenic sepsis workup." Three traps to avoid. Reading the mouth ulcers as thrush or a minor side effect, when the source names them as a sign of impending toxicity. Treating the fever as a flare in a patient whose white count is 1.6. And leaving the ibuprofen in place because it seems unrelated to the ulcers — it is not; it raises the toxicity of the drug that caused them.

  6. 6
    Evaluate

    Over the next days, success looks like: counts recovering after leucovorin, transaminases falling, creatinine returning toward 0.9 with rehydration, ulcers healing, and no documented infection. Methotrexate is restarted only when the team judges it safe, and restarted weekly, with teach-back documented. Longer term, the plan gets rebuilt around the guideline: a treat-to-target approach with low disease activity as the initial goal, methotrexate as the anchor if it can be resumed, and a plan to end the prednisone bridge — because ACR 2021 strongly recommends starting a conventional DMARD without glucocorticoids lasting 3 months or more, and she is already at week seven. The re-escalation triggers she leaves with: mouth sores, fever, unusual bruising or bleeding, and any new breathlessness or dry cough — the last of which could be pneumonitis from the drug or interstitial lung disease from the disease, and is evaluated either way.

Scenario — you’re the nurse

Work each question before revealing the answer. Rationales explain the wrong options too.

Rheumatology clinic, urgent review triggered by a phone call · 1000

A 68-year-old woman with seropositive rheumatoid arthritis diagnosed 7 weeks ago. She was started on methotrexate 15 mg once weekly with folic acid, plus a short prednisone bridge. She telephoned this morning because her mouth is "full of ulcers" and she feels exhausted. On questioning she says she has been taking "the yellow tablets" every morning with breakfast since the day she got them. She also mentions she has been buying ibuprofen for her hands because "the methotrexate has not kicked in yet."

1000 vitals — HR 98 · BP 112/68 · RR 18 · T 38.1 °C · looks pale and unwell
Mouth — multiple painful ulcers on the buccal mucosa and tongue; she is struggling to eat or drink
Skin — scattered bruising over both forearms that she cannot account for
Medication history — methotrexate 15 mg taken DAILY for 7 weeks · folic acid taken "sometimes" · prednisone 7.5 mg daily · ibuprofen 400 mg three times daily, self-purchased
Bloods drawn on arrival — WBC 1.6 ×10⁹/L · platelets 68 ×10⁹/L · Hb 9.2 g/dL · ALT 214 U/L · creatinine 1.6 mg/dL (baseline 0.9)
Q1 Select all that apply
Which findings require immediate action? Select all that apply.
  1. A. Methotrexate 15 mg taken daily for 7 weeks when prescribed weekly
  2. B. Multiple painful oral ulcers
  3. C. WBC 1.6 ×10⁹/L with a temperature of 38.1 °C
  4. D. Self-purchased ibuprofen 400 mg three times daily
  5. E. Prednisone 7.5 mg daily as a bridge
Reveal answer & rationale
Answer: A, B, C, D
Daily instead of weekly dosing (A) is the root cause and the reason the source warns that "improper daily use of the recommended dose has led to fatal toxicity." The oral ulcers (B) are not a nuisance — "mucosal ulceration… may be a sign of impending methotrexate toxicity." A white count of 1.6 with fever (C) is neutropenia plus fever and must be worked up as infection, not attributed to disease activity. The ibuprofen (D) requires action because NSAIDs "increase the risk of MTX toxicity," so it is actively worsening the overdose. The prednisone bridge (E) is the one item that does not require immediate action — it is consistent with sourced practice for a newly diagnosed patient, though it does need a planned end, since ACR 2021 strongly recommends against glucocorticoids continuing 3 months or more.
Q2 Multiple choice
The nurse understands that the most important immediate action is to:
  1. A. Give an antifungal mouthwash for the oral ulcers and review in a week
  2. B. Stop the methotrexate and the ibuprofen, and escalate urgently for possible leucovorin rescue
  3. C. Increase the prednisone dose to control what appears to be a disease flare
  4. D. Reassure her that mouth ulcers are a common early methotrexate effect that settles
Reveal answer & rationale
Answer: B
Stopping the offending drug is the treatment, and the NSAID is stopped with it because it raises methotrexate toxicity; leucovorin "rescues normal cells from the toxic effects caused by MTX’s inhibition of reduced folates," with glucarpidase available to cut levels by 97% or more within 15 minutes (B). Treating the ulcers symptomatically (A) misses that they are a toxicity signal and leaves a daily overdose running. Increasing prednisone (C) misreads marrow suppression and hepatotoxicity as a flare and deepens immunosuppression in a neutropenic, febrile patient. Reassurance (D) is the most dangerous option of the four — it normalizes exactly the finding the source flags as impending toxicity.
Q3 Put in order
Put the nurse’s actions in priority order:
  1. A. Obtain blood cultures and escalate for neutropenic fever evaluation
  2. B. Stop the methotrexate and the ibuprofen
  3. C. Provide teach-back education on weekly-only dosing before discharge
  4. D. Repeat CBC, creatinine and transaminases
Reveal answer & rationale
Correct order: B → A → D → C
Stopping both drugs (B) comes first: it costs nothing, needs no result, and halts the ongoing injury. Cultures and neutropenic fever escalation (A) follow immediately, because a white count of 1.6 with a temperature of 38.1 °C is a potential sepsis and delay there is what kills. Repeating the monitoring bloods (D) tracks the trajectory and informs the rescue decision, but the first set already establishes the emergency. Teach-back education (C) is the intervention that prevents this ever happening again and must not be skipped — but it belongs at discharge, to a patient who is safe and well enough to absorb it.
Q4 Multiple choice
Ten days later she is recovering and asks whether she can restart ibuprofen for her hands. The best response is:
  1. A. "Yes — ibuprofen is safe with methotrexate as long as you take it with food."
  2. B. "NSAIDs increase methotrexate toxicity, so any pain reliever needs to go through the team first — and NSAIDs do not slow the disease anyway."
  3. C. "You should use a stronger NSAID instead, since ibuprofen was not controlling the pain."
  4. D. "Avoid all pain relief until the methotrexate reaches full effect."
Reveal answer & rationale
Answer: B
NSAIDs "increase the risk of MTX toxicity," and they "do not have any disease-modifying effects" and are used for symptom relief — so the risk is real and the benefit is limited to comfort (B). The same interaction applies to trimethoprim-sulfamethoxazole and proton pump inhibitors, which is why the whole medication list goes through the team. Option A is factually wrong about the interaction. Option C makes the problem worse by increasing NSAID exposure. Option D overcorrects into leaving a patient in pain — pain relief is appropriate, it simply has to be chosen with the interaction in mind, and the guideline itself makes no NSAID recommendation for rheumatoid arthritis at all.
Q5 Multiple choice
At her next review she asks, "Should I be resting my hands so I do not wear the joints out?" The best response is:
  1. A. "Yes — resting inflamed joints prevents further damage."
  2. B. "Consistent exercise is strongly recommended over no exercise, and hand therapy exercises and joint protection techniques are recommended alongside it."
  3. C. "Exercise is only safe once you reach remission."
  4. D. "It makes no difference either way, so do whatever feels comfortable."
Reveal answer & rationale
Answer: B
"Consistent engagement in exercise is strongly recommended over no exercise" is the single strong recommendation in the ACR 2022 rehabilitation guideline, with aerobic, aquatic, resistance and mind-body exercise all conditionally recommended, plus hand therapy exercises and joint protection techniques for hand involvement (B). Prescribing rest (A) inverts the evidence — and note that rest is what relieves osteoarthritis, where pain "is typically related to activity and resolves with rest," whereas rheumatoid stiffness is worst after rest and eases with movement. Waiting for remission (C) invents a precondition no source states. Option D discards a strong recommendation and leaves the patient without guidance.

Common questions

What causes rheumatoid arthritis?
Common causes and risk factors include cigarette smoking — "the strongest environmental risk factor," acting by driving citrullination in the lung, periodontal disease, with porphyromonas gingivalis named — citrullination in the gums, obesity — a bmi over 30 kg/m² confers a 30% increase in risk; a western diet high in calories and low in fiber is also implicated, occupational exposure to silica, asbestos or textile dust, older age — peak incidence between 65 and 80 years, not the classically taught 30 to 50, and others.
What are the early signs of rheumatoid arthritis?
Early findings include Symmetric swelling and pain in the MCP, PIP, MTP and wrist joints — with the DIP joints spared, Morning stiffness lasting more than 1 hour, easing with movement, Insidious onset over weeks to months.
Which findings should a nurse report immediately in rheumatoid arthritis?
Report immediately: Swelling that feels boggy — with warmth and redness usually ABSENT, Sudden inability to extend the ring and little fingers, New or worsening breathlessness or a dry cough, New neck pain, restricted neck movement, arm weakness or gait change, Cardiovascular disease and interstitial lung disease — the mortality drivers, and others. These signal deterioration that needs rapid intervention.
How is rheumatoid arthritis different from osteoarthritis?
They differ in almost every dimension a nurse can assess. Joints: rheumatoid arthritis takes symmetric small peripheral joints — MCP, PIP, MTP and wrists — with the DIP joints spared and cervical but not lumbar spine involvement; osteoarthritis takes larger weight-bearing joints asymmetrically and produces DIP nodes. Stiffness: rheumatoid morning stiffness lasts more than 1 hour and eases with movement; osteoarthritic stiffness lasts less than 30 minutes, with pain that follows activity and resolves with rest — so rest helps osteoarthritis and hurts rheumatoid arthritis. Labs: rheumatoid arthritis shows RF and anti-CCP positivity with raised ESR and CRP; in osteoarthritis blood tests "are usually normal." X-ray: both narrow the joint space, but only rheumatoid arthritis erodes (periarticular osteopenia and marginal erosions) and only osteoarthritis grows osteophytes. In short: RA involves small joints symmetrically, with prolonged inflammatory morning stiffness; OA involves larger weight-bearing joints asymmetrically, with morning stiffness lasting under 30 minutes.
Why is methotrexate taken weekly, and what happens if it is taken daily?
Methotrexate is a folate antagonist, and in rheumatoid arthritis it is dosed once weekly — sources give a starting range of 7.5 to 15 mg weekly, titrated toward 20 to 25 mg weekly. The frequency is the part that is identical in every source, and it is not negotiable: the drug chapter states plainly that "improper daily use of the recommended dose has led to fatal toxicity." Daily dosing delivers roughly seven times the intended exposure, and the organs that fail are predictable — mucosa first ("mucosal ulceration… may be a sign of impending methotrexate toxicity"), then bone marrow (aplastic anemia, bruising, bleeding, infection), liver (hepatotoxicity, "the most significant adverse effect"), and kidney. Rescue exists: leucovorin protects normal cells, and glucarpidase "reduces plasma methotrexate concentrations by 97% or more within 15 minutes." Prevention is a teaching task — confirm the weekly schedule by teach-back, confirm folic acid (1 mg/day or 5 to 7 mg weekly), and review every co-prescribed drug, because NSAIDs, trimethoprim-sulfamethoxazole and proton pump inhibitors all raise methotrexate toxicity.
Should a patient in remission stop their DMARD, and how long should the steroids last?
No on both counts, in different ways. DMARDs: for patients who have been at target for at least 6 months, the 2021 ACR guideline ranks three options, and the first is to change nothing — continuing all DMARDs at the current dose is conditionally recommended over dose reduction, then dose reduction over gradual discontinuation, then gradual discontinuation over abrupt discontinuation. So doing well is first a reason to leave the regimen alone; if a reduction is undertaken at all, it is stepwise rather than a stop. Steroids: the same guideline is unusually blunt — "Initiation of a csDMARD WITHOUT longer-term (≥3 months) glucocorticoids is STRONGLY recommended" over starting one with them, because "the toxicity associated with glucocorticoids was judged to outweigh potential benefits." A short bridge while a DMARD takes effect remains standard practice, but it should have a planned end. The reason is specific to this disease: rheumatoid arthritis already carries a 60% to 100% increased fracture risk and independently accelerates coronary artery disease, and glucocorticoids worsen both.
