Small vessel hypersensitivity vasculitis

This section deals with the clinical condition small vessel hypersensitivity vasculitis, listing the relevant immunological tests, together with a short explanation of their use.

Relevant immunological tests:

Infection, drugs, foreign proteins (as examples) may be causal factors in a vasculitis affecting predominantly the skin.

Immunological findings may sometimes include raised ESR/CRP, depressed levels of complement factors suggesting consumption, and the presence of antinuclear antibodies and rheumatoid factor (low titre).

General screening tests for vasculitis should also include serum immunoglobulins, and ANCA.

If there is evidence for more extensive visceral involvement, one of the primary systemic vasculitides may be involved.

Alternatively, the vasculitis may be secondary to autoimmune disease (eg. SLE, chronic active hepatitis), neoplasia (eg. lymphoma), cryoglobulinaemia (these are immunoglobulins that form precipitates in the cold).
