A prospective study of the natural history of acute hepatitis B was performed in 38 patients. Fatigue started median 4 weeks, abdominal symptoms median 3 weeks and signs of cholestasis median 2.5 weeks before peak SGPT values were reached. Extrahepatic manifestations occurred throughout the prodromal stage, the presence of arthropathy, urticaria or skin rashes was not related to the biochemical severity of liver disease. The higher the the maximal values of serum bilirubin and/or the older the patient, the longer the period of bilirubin elevation; a maximal bilirubin elevation less than 20 X the upper limit of normal was associated with normalisation of serum bilirubin within 6 weeks. No such correlations were found between the height of serum glutamic pyruvic transaminase, alkaline phosphatase, thymol turbidity and cholesterol levels and the subsequent duration of their abnormality. The elevation of alkaline phosphatase as well as the abdominal complaints might partly be caused by gastro-intestinal involvement. Immobilisation before peak SGPT was attained was associated with normalisation of serum glutamic pyruvic transaminase levels within 8 weeks after peak levels. 37 patients recovered completely. In one HBs-antigenemia and slight SGPT elevation persisted. Long term follow up was possible in 33 patients for 4 to 7 years, median 5 years.

To determine whether skin deposition of circulating immune complexes contributes to prodromal urticaria of acute hepatitis B, we studied two patients with hepatitis B who presented with urticaria and fever. During the urticarial prodrome but not thereafter, we found activation of both classic and alternative complement pathways. Hepatitis B surface antigen (HBsAg)-antibody complexes were identified (by electron microscopy) in cryoprecipitates from both patients and IgG (by immunodiffusion) in cryoprecipitates of one patient during urticaria. Light and electron microscopy of involved urticarial skin revealed necrotizing venulitis in both patients. Immunofluorescence microscopy showed fibrin within involved cutaneous vessel walls in one patient and C3, IgM, and HBsAg, which were not detected in simultaneously obtained uninvolved skin, in both patients. Our findings suggest that deposition of circulating immune complexes containing HBsAg is important in the pathogenesis of urticaria associated with acute hepatitis B virus infection.

A previously well young woman presented with an acute hepatitis resembling viral hepatitis and a liver biopsy after 5 weeks showed features of acute hepatitis. Infection with identifiable viruses or other organisms known to cause hepatitis was excluded. Evidence for autoimmune chronic active hepatitis ab initio included prolonged fever, lymphadenopathy, urticaria, arthralgia, Coombs' positive hemolytic anemia, lymphopenia, a markedly raised level of immunoglobulin G and a positive antinuclear antibody test. Liver biopsies after 4 and 28 months showed typical histologic features of autoimmune chronic active hepatitis and the subsequent clinical course was typical, being marked by relapses and remissions responsive to prednisolone. Thus, described here is a woman in whom an acute onset of autoimmune chronic active hepatitis was clinically and histologically identified.

Urticaria has been described only rarely in patients with hepatitis A virus infection, although its association with acute hepatitis B virus infection is well recognized. A young male homosexual presented with hepatitis and urticaria, which proved to be an acute hepatitis A virus infection. In one study of a foodborne outbreak of hepatitis A virus, 2/130 patients developed hives. A few other isolated cases of presumed hepatitis A virus infection and urticaria have been reported, but this is the first detailed description of a serologically proven hepatitis A virus infection associated with the development of urticaria, in which no other risk factor could be implicated.

Multiple sclerosis (MS) is a chronic inflammatory disease with demyelination of the central nervous system. High-dosage corticosteroids are the first-line therapy in the acute relapsing of MS. We report a case of severe high-dose methylprednisolone-induced acute hepatitis in a patient with a new diagnosis of MS. A 16-year-old girl was admitted for urticaria, angioedema, nausea and vomiting a month later she had been diagnosed with MS and treated with high-dosage methylprednisolone. Laboratory investigations showed hepatic insufficiency with grossly elevated liver enzymes. A liver biopsy showed focal centrilobular hepatocyte necrosis with interface hepatitis. Methylprednisolone-induced hepatotoxicity can confuse the clinical picture of patients with MS and complicate the differential diagnosis. We believe that each specialist should know it and monitor patients with MS taking high doses of methylprednisolone. As there is no screening model that predicts idiosyncratic hepatotoxicity, we promote screening for potential liver injury following pulse steroid therapy.
