We report a case of hypocomplementemic urticarial vasculitis (HUV). The clinical course was characterized by urticaria, angio-edema, pericarditis, joint pain and conjunctivitis. The laboratory findings revealed moderate proteinuria, erythrocyturia, normal renal function, normotension, reduction of C3, C4 and C1q complement with elevated C1q antibodies. Antinuclear antibodies were inconstantly positive. Renal biopsy showed a mild form of membranous glomerulonephritis. Despite intensive therapeutic measures (dapsone, immunosuppressives and immunoglobulins), relapses of urticaria occurred frequently. HUV is probably a minor form of systemic lupus erythematosus.

Infection with hepatitis B virus (HBV) can result in hepatic diseases which may include an asymptomatic non-replicative carrier state, immunotolerant phase characterized by high DNA levels without significant hepatic injury, immune-reactive phase characterized by occurrence of chronic hepatitis and fibrosis in the liver, or complications like cirrhosis or hepatocellular carcinoma. Extrahepatic manifestations may also accompany HBV infection. These may include serum sickness syndrome, polyarthralgia, polyarthritis, dermatologic manifestations like pitted keratolysis, urticaria, purpura, oral lichen planus or Gianotti-Crosti syndrome-a childhood papular eruption. Renal involvement may occur with HBV infection and usually involves glomerular or vascular injury. Various morphologic forms of renal injury have been reported with HBV infection, the commonest being membranous glomerulonephritis. The manifestations may include swelling over face and body, pedal edema, and urinary abnormalities. Evaluation may detect proteinuria, hematuria and reduction in estimated glomerular filtration rate (GFR). The management options include use of antiviral drugs targeting HBV infection with or without concomitant immunosuppressive medication. With availability of newer drugs like entecavir and tenofovir, these have become the first line agents as they have a high barrier to resistance. Sole use of immunosuppression is not recommended for lack of clear benefit and the possible risk of HBV reactivation or flare.

Rituximab is a monoclonal antibody directed against B cells and is being increasingly used for various renal indications. Acute dermatologic manifestations such as urticaria are well known to occur during rituximab infusion. Here, we report the case of a 53- year-old female who was treated with rituximab for membranous nephropathy and developed an exanthematous rash, which progressed with a further dose of rituximab and was diagnosed as urticarial dermatitis. A review of literature showed that urticarial dermatitis following rituximab therapy has been seldom reported and identification of this complication is very important to avoid giving further doses and thus, increasing the severity of lesions.
