Rheumatology Flashcards
Rheumatoid arthritis respiratory complications
- pulmonary fibrosis
- pleural effusion, pleurisy
- pulmonary nodules
- bronchiolitis obliterans
- methotrexate pneumonitis
- caplan syndrome (RA + massive lung fibrosis with pneumoconiosis e.g. coal worker’s lung, berylliosis, asbestosis, silicosis)
Ocular features of rheumatoid arthritis
- keratoconjunctivitis sicca (most common)
- episcleritis/scleritis
- corneal ulceration
- keratitis
- steroid-induced cataracts
- chloroquine retinopathy
Neuromuscular complications of rheumatoid arthritis
- vasculitis: nail fold infarcts, mild sensory neuropathy, (rarer: cutaneous ucleration, mononeuritis multiplex, mesenteric / cerebral / coronary artery involvment)
- entrapment neuropathies (e.g. CTS)
- osteoporosis
- ligamentous laxity (atlantoaxial subluxation, subaxial subluxation i.e. lower cervical spine)
- tenosynovitis
Reactive arthritis features
- asymmetrical oligoarthritis of lower limbs
- dactylitis
- urethritis
- eye: conjunctivitis (seen in 50%), anterior uveitis
- skin: circinate balanitis (painless vesicles on the coronal margin of the prepuce), keratoderma blenorrhagica (waxy yellow/brown papules on palms and soles)
Mx
- treat precipitating infection
- NSAIDs -> intra-articular steroid -> systemic steroid
Relapsing polychondritis mx
1) Steroids to induce
2) Maintenance with azathioprine / methotrexate / ciclopsorin
Takayasu arteritis clinical features
- large vessel vasculitis, varying pattern
- systemic features of a vasculitis e.g. malaise, headache
- unequal blood pressure in the upper limbs. May have subclavian steal syndrome
- carotid bruit
- intermittent claudication, especially arm
- aortic regurgitation (around 20%)
- assoc w/ RAS
Takayasu arteritis Ix
- angiography
- ANCA not associated
Takayasu arteritis mx
1) steroids
2) immunosuppression
Polyarteritis nodosa features
Medium-sized artery vasculitis
- general: fever, weight loss, malaise
- mononeuritis multiplex
- large joint arthralgia
- GI: abdo pain, GI haemorrhage
- renal: haematuria, renal failure, hypertension
- livedo reticularis
Polyarteritis nodosa ix & mx
- pANCA 20%
- hep B 30%
- angiography
Mx
- prednisolone
- cyclophosphamide
Scleroderma renal crisis
Mx: ACEi
- > ramipril if moderate
- > captopril (fast acting) if severe
Management of systemic sclerosis associated ILD
MMF or cyclophosphamide
Adult onset still’s disease features
- arthralgia
- pink maculopapular rash
- pyrexia which is worse when pain / rash is worst
- LNs
- RF / ANA -ve
Mx adult onset still’s disease
1) NSAIDs +/- steroids
2) Methotrexate
3) Biologics
- Etanercept (anti-TNF)
- anakinra, canakinumab (IL1 inhib),
- Tocilizumab (anti-IL6)
4) Rituximab
Psoriatic arthritis features
- 10-20% psoriasis get arthropathy
Patterns
- RA
- sacroilitis
- DIPJ
- asymmetrical oligoarthritis
Ix
- DIPJ pencil in cup
- RF 10%
- low ANA+ve
