(Polyarthritis)

anti-dsDNA is highly specific for:
SLE
anti-Smith is highly specific for:
SLE
anti-Mi-2 is highly specific for:
Dermatomyositis
(but only present in 25%)
anti-Jo-1 is seen in

Initial management of RA
DMARD monotherapy (usually methotrexate)
+/- bridging steroids

TNF-inhibitors:
Etanercept
Infliximab
Adalimumab
Before starting TNF-inhibitor
Screen for TB, Hep B
(+/-Hep C if risk) due to risk of re-activation
Abatacept (anti-CTLA4) used in
RA not controlled with anti-TNF therapy
Canakinumab (anti-IL1) used in
Gout flares
Resistant Still’s disease
Management of RA - next step after TNF inhibition
Rituximab (anti-CD20)

Management of dermatitis herpetiformis
GF diet
Topical dapsone
