What are the 4 seronegative causes of inflammatory arthritis
Psoriatic arthritis
Reactive arthritis
Ankylosing spondylitis
Enteropathic arthritis
Generalised features of seropositive arthritis
Affect women more than men
Symmetrical polyarticular small and large joints
DIP spared
+ve RF/CCP
No pelvic/spinal involvement
Nodules, vasculitis, Raynauds, scleritis/episcleritis, photosensitivity, pulmonary involvement
Generalised features of seronegative arthritis
Affect men more than women Asymmetrical oligoarticular large joints -ve RF/CCP DIP affected in psoriatic Pelvic and spinal involvement common Iritis, uveitis, oral ulcers, enthesitis, GI, GU and derm pathology
Hand/wrist examination findings in rheumatoid arthritis
Symmetrical small joint polyarthritis affecting wrists, MCPs, PIPs, ankles, elbows

Pleuritis/pleural effusion
Pericarditis/pericardial effusion
Scleritis/episcleritis/scleromalacia perforans/keratoconjunctivitis sicca
Palmar erythema, nail fold infarcts
Caplans syndrome - pulmonary nodules, splenomegaly and low blood count (RBC, WBC, both)
Felty’s syndrome - RA, splenomegaly and neutropenia

What is the name of the criteria classification system used to diagnose rheumatoid arthritis
ACR classification criteria
What tool can be used to assess severity of rheumatoid arthritis
DAS-28 score
Management of rheumatoid arthritis
Refer to rheumatology Manage CVD risk factors (at increased risk) NSAIDs Steroids DMARDs/biologics
Typical presentation of reactive arthritis
Young male a few weeks after GU/GI infection
Uveitis/conjunctivitis + Urethritis + Arthritis
What is the pattern of joint involvement for reactive arthritis
Asymmetrical oligoarticular large joints of lower limbs/back
What is the pattern of joint involvement for psoriatic arthritis
Asymmetrical mono/oligoarticular larger joints
5 patterns:
1. DIP arthritis
2. Asymmetrical oligoarticular
3. Symmetrical polyarticular
4. Arthritis mutilans
5. Psoriatic spondylitis + sacroiliitis + spinal involvement
Clinical findings of ankylosing spondylitis
Asymmetrical mono/oligoarticular large joints Sacroiliac tenderness Loss of lumbar lordosis Kyphosis Iritis/uveitis
Clinical feature of SLE
Symmetrical arthritis and chronic arthralgia
Malar butterfly rash, discoid rash, photosensitivity
Fatigue, weight loss, fever, lymphadenopathy
Raynauds
Jacouds arthritis

Nephritic syndrome
VTE (APS)
CNS signs - seizures, psychosis, cognitive defects
Anaemia, lymphopenia, neutropenia, thrombocytopenia
Abdo pain, diarrhoea, vomiting
What is the name of the classification system used to help diagnose SLE
ACR criteria
Which special blood tests are positive in SLE
Double stranded DNA
ANA
Anti-phospholipid antibodies
Management of SLE
Rheumatology referral CVD risk factor management Sun protection NSAIDs Steroids Hydroxychloroquine, MTX Renal assessment/involvement
