Bridging necrosis was recorded in 14% of 361 patients with acute viral hepatitis on examination of the liver biopsy. The clinical and biochemical features of acute viral hepatitis with bridging necrosis were compared with acute viral hepatitis with no bridging necrosis (NBN). It was noted that fever of more than 8 days' duration in the preicteric phase, the presence of mild ascites and pedal edema during the icteric phase, increasing or persistently high levels of serum bilirubin even 4 weeks after the onset of the icteric phase and positive hepatitis-B surface antigen were significantly more common in acute viral hepatitis with bridging necrosis. Hepatitis-B surface antigen clearance was slow in this group. The long-term complication of chronic hepatitis was more frequent in patients with acute viral hepatitis with bridging necrosis.

Diaminodiphenyl sulphone (dapsone) is a drug of choice in the treatment of leprosy. It is also useful for the treatment of many neutrophilic and other dermatoses. Dapsone hypersensitivity syndrome is a rare but well recognized serious adverse effect characterized by fever, skin rashes, generalized lymphadenopathy, hepatitis, and hepato-splenomegaly. Twenty-six patients with dapsone hypersensitivity syndrome were studied for clinical profile, outcome, and prognosis. The male:female ratio was 2.2:1, and the mean age was 33.19 years (range 13 to 64 years). The interval between start of dapsone therapy and appearance of symptoms varied from 2-7 weeks (mean 29.82 days). Twenty-four patients received dapsone as a part of multi-drug therapy for leprosy; the other two patients received dapsone for lichen planus and acne vulgaris. Exfoliative dermatitis was the most common cutaneous manifestation followed by erythematous maculo-papular eruption and Stevens-Johnson syndrome-like lesion. The other common systemic manifestations were: fever (26 cases), itching (22 cases), lymphadenopathy (21 cases), jaundice (21 cases), pallor (20 cases), hepatomegaly (19 cases), and pedal edema (14 cases). Investigation profile revealed elevated levels of serum liver enzymes in 100% of patients, elevated erythrocyte sedimentation rate in 92.3%, raised bilirubin in 84.6%, leucocytosis in 69.23%, low hemoglobin (<9 gm/dl) in 46.15% and hypoproteinemia in 42.3%. Eosinophilia, hemolytic anemia, and reticulocytosis count were found in 4 patients each. All the patients had favorable outcomes except three who died due to hepatic failure. Medical personnel must be aware of this potentially fatal syndrome, because it can cause considerable morbidity and mortality.

Membranous nephropathy (MN) associated with malignancies is a well-known entity. However, its association with benign neoplasm is not broadly recognized. A 69-year-old man with recurrent nephrotic syndrome presented with pedal edema and proteinuria of 5 months' duration. Laboratory results showed hypoalbuminemia and hyperlipidemia. Proteinuria was estimated to be protein excretion of 3.5g/d. Studies were negative for viral hepatitis, syphilis, human immunodeficiency virus, autoimmune diseases, and paraproteinemia. Kidney biopsy disclosed MN with negative phospholipase A2 receptor (PLA2R) staining, favoring a secondary form of MN. Computed tomography detected a 7.6-cm duodenal schwannoma. Elective surgical resection was performed. Pathologic study showed that THSD7A (thrombospondin type 1 domain-containing 7A) was positive in both glomeruli and schwannoma. Commonly, secondary MN is related to underlying conditions, including lupus, hepatitis, and neoplasm, and can be medication induced. The risk for developing a concomitant neoplasm among patients with PLA2R-negative MN is up to 12 times higher than in the general population. Most of these neoplasms are malignancies, and the presence of autoantibodies directed at similar tissue targets is hypothesized as the potential mechanism. In our case, THSD7A may be the autoantibody that has linked the schwannoma and the development of MN. Although benign tumors rarely produce renal manifestations, effective treatment may lead to resolution of nephrotic syndrome.
