Essential mixed cryoglobulinemia type III with leukocytoclastic vasculitis: remission by rituximab

Abstract

We report about a 39-year-old female patient with severe essential mixed cryoglobulinemia of type III with leukocytoclastic vasculitis. The patient was admitted into our hospital with mesenteric lymphangiitis, which caused enteral perforation, sepsis, and pneumonia. Cryoglobulins, cryocrit, Ig-titers, and biopsy were positive for mixed cryoglobulinemia type III. We detected no signs of hepatitis C, B, or any other infectious disease. At first, disease activity could be kept under control with high doses of glucocorticoids and multiple cyclophosphamide pulses. However, after therapy with three pulses of rituximab, steroids were stopped, and the patient has not presented any symptoms for 2 years. Therefore, we suggest that rituximab affected her disease rapidly and effectively. In conclusion, rituximab is an alternative therapy for mixed cryoglobulinemia of type III with leukocytoclastic vasculitis.

Vasculite leucocitoclástica e infecção crónica por Hepatite B

A vasculite leucocitoclástica por depósitos de crioglobulinas é frequentemente associada a infecção pelo vírus da hepatite C 6,7 , sendo a sua relação com a infecção pelo vírus da hepatite B é algo controversa, havendo no entanto alguns casos relatados 8,9,10 .…”
