Isolated digital gangrene complicating hepatitis a infection in a child.

Hepatitis A virus is rarely associated with extrahepatic complications. A child presented with a history suggesting Raynaud's phenomenon and severe digital gangrene, as a complication of hepatitis A infection. Coagulation study results (protein C, protein S, antithrombin III, and activated protein C resistance) were all normal except for anticardiolipin antibodies, which were present on initial presentation and resolved later.

Anticardiolipin antibodies in patients with retinal vein occlusion and no risk factors: a prospective study.

Background: Several reports have described the association between antiphospholipid antibodies (APAs) and retinal venous occlusive (RVO) disease. The purpose of this study was to look at the prevalence of these antibodies in patients with RVO disease and no conventional risk factors. We specifically examined how APAs may affect the course of this disease.
