Indian childhood cirrhosis is a significant cause of morbidity and mortality in young children in India. One hundred patients with ICC, 66 boys and 34 girls, were studied. Pedigree analysis yielded a segregation ratio of 0-2196, suggestive of an autosomal recessive inheritance. Serum alpha1-antitrypsin level was normal. Serum alpha-foetoprotein (AFP) concentration was increased in all the patients, parents and in some siblings. Serum immunoglobulins G, A, M, and D were elevated. Haemolytic complement and C3 were low. Electrophoretically altered complement components were detected in 36% of patients. There was an inverse relationship between C3 concentration and immunoconglutinin titre. Circulatingimmune complexes were detected in the sera of six out of ten patients who had significant proteinuria. Hepatitis B surface antigen (HBsAg) was present in the serum, ascitic fluid, saliva, urine and faeces of ICC patients more frequently than in controls. HBsAb was detected less often. Lymphocyte response to HBsAg was impaired. The first-degree relatives had a higher incidence of HBsAg and HBsAb than healthy controls. It is suggested that ICC occurs in infants with an inherited hepatocyte vulnerability and that one of the precipitating causes of liver cell necrosis is infection with hepatitis virus(es). The consequent immunologic epiphenomena contribute to progressive hepatic damage ending in death.

Renal histology in 163 Japanese children, aged 3 to 15, with proteinuria and/or haematuria showed that 11 had membranous nephropathy (M.N) and the rest had various other renal diseases. Hepatitis-B-virus surface antigen (HBsAg) was identified, by a reversed passive haemagglutination method, in the serum of all the patients with M.N. but in only 4.6% of the patients with other renal diseases. 6 of the 11 mothers of the children with M.N. were positive for HBsAg, and 1 was positive for antibody to HBsAg (anti-HBs). These findings suggest that M.N. in Japanese children is mainly, if not exclusively, caused by hepatitis-B virus and that in most instances the virus is transmitted from mother to child.

The course of disease of a patient with membranoproliferative glomerulonephritis and partial lipodystrophy is described. The case is further characterized by a deficiency of C3 and C3- activator, by normal values of C4, by evidence of the nephritogenic factor, by raised fibrin degradation products and by an unselective proteinuria. The course of the glomerulonephritis runs parallel to a pronounced susceptibility to infection (at first varicella, tonsillitis and measles, later pneumonia, meningitis, encephalitis and hepatitis). On account of a nephrotic syndrome and an initative impairment of the renal function, a cytostatic treatment was begun, which although raising the C3 level did not influence the further course of the disease. As the patient has a healthy identical twin sister without lipodystrophy, who shows no reduction in C3 and no nephritogenic factor, this case proves that these diseases are acquired and not genetically determined.

A case is described in which a patient developed TT prolongation and bleeding during CMV hepatitis following successful renal transplantation. Bence-Jones proteinuria was noted, but there was no other evidence of myeloma. Bence-Jones proteinuria, TT prolongation, and bleeding abated as hepatitis resolved. In vitro, a protein isolated from the patient's urine was capable of prolonging the TT markedly, but it did not impair thrombin esterase activity. The effect of the protein seemed to be inhibition of fibrin polymerization. Sephadex gel filtration revealed a single TT-prolonging peak at 11,000 daltons, containing kappa, lambda, and delta antigens. By radioimmunoassay, virtually all the protein present reacted as beta2-microglobulin. Incubation with anti-beta2-microglobulin antiserum markedly attenuated anticoagulant activity. The paraprotein observed transiently in this patient's urine during hepatitis had potent anticoagulant activity and may well have accounted for his abnormal TT and bleeding diathesis; this paraprotein was not distinguishable from beta2-microglobulin.

A patient developed hepatitis after receiving three halothane anaesthetics in 22 days. Twenty-four hours after the onset of jaundice she developed an acute serum sickness syndrome with polyarthralgia, proteinuria, and transient impairment of renal function. Serum concentrations of complement components C1q, C4, and C3 were substantially reduced, and immune complexes capable of activating the complement system via the classical pathway were present in the serum and synovial fluid. A metabolite of halothane was associated with these complexes. Fourteen months after exposure to halothane her lymphocytes were stimulated in vitro by this metabolite. The conditions under which stimulation occurred were unusual--namely, a 7S fraction of the serum, presumably IgG, was necessary. Our results provide strong evidence that halothane may be immunogenic and that its immunogenicity is dependent on the non-covalent binding of one of its metabolites to plasma proteins.

The objective of this study was to characterize the hemostatic defect in dogs with infectious canine hepatitis (ICH), a naturally occurring viral disease of dogs. Five littermate dogs were inoculated with 10(3) TCID50 of ICH virus intravenously. Two littermates were controls. The clinicopathologic manifestations of ICH were fever, depression, anorexia, hematemesis, melena, widespread mucocutaneous petechiae, prolonged bleeding from venipunctures, faceial edema, leukopenia, and proteinuria. The hemostatic defect of ICH was characterized by thrombocytopenia, abnormal platelet function, prolonged one-stage prothrombin time and activated partial thromboplastin time, normal thrombin times, depressed factor VIII activity, and increased fibrin-fibrinogen degradation products. These findings suggested that the central pathologic mechanism of the abnormal hemostasis in ICH was disseminated intravascular coagulation (DIC). ICH is an example of DIC induced by viral infection. This disease is a suitable model for investigation of the detection, pathogenesis, and therapy of DIC.

This is a case report of a 35-year-old female who showed a relatively short clinical course of severe liver cirrhosis and proteinuria. On light microscopical studies of autopsy material, besides active postnecrotic type liver cirrhosis, typical membranous glomerulonephritis was found. Immunofluorescent study disclosed not only clustered HBsAg (hepatitis type B surface antigen) in occasional hepatic cells but also beaded granular type deposition of HBsAg, IgG, IgM, IgA and complement C3 along renal glomerular basement membrane (GBM). Electron microscopical study disclosed multiple particulated material in occasional inclusion bodies of hepatic cells and in subepithelial and subendothelial dense deposits along the GBM. Enzymatic immunoelectron microscopical study confirmed these particles especially along the GBM being HBsAg themselves. It was concluded that HBsAg-Ab (antibody) complex was the pathogenetic factor responsible for the glomerular change of this particular case. Although HBsAg and Ab were examined to be negative in serum throughout the patient's clinical course, the possibility of the presence of circulating HBsAg-Ab complex in serum was discussed.

Severe hepatotoxicity from phenobarbital occurred in an infant boy who had a complicated illness with chronic bilateral subdural hematomas and sepsis. Skin rash began after 2 weeks of treatment, and signs of hepatocellular failure developed 3 weeks after phenobarbital had been started. Signs of severe liver disease included elevated aminotransferases, conjugated hyperbilirubinemia, significant coagulopathy, hepatosplenomegaly and ascites. Other features of this adverse drug reaction were unremitting fever, leukocytosis with eosinophilia and atypical lymphocytosis, and proteinuria. Sepsis, viral hepatitis, and metabolic liver disease were excluded. The child was on no other medication and had been previously well. In-vitro rechallenge of the patient's lymphocytes with cytochrome P-450 generated metabolites of phenobarbital showed extensive cytotoxicity compared to control. These data support the hypothesis that a defect in drug detoxification was responsible for the child's susceptibility to this drug hepatotoxicity.

Hantaviruses, the causative agents of HFRS, have become more widely recognized. Epidemiologic evidence indicates that these pathogens are distributed worldwide. People who come into close contact with infected rodents in urban, rural and laboratory environments are at particular risk. Transmission to man occurs mainly via the respiratory tract. The epidemiology of the hantaviruses is intimately linked to the ecology of their principal vertebrate hosts. Four distinct viruses are now recognized within the hantavirus genus and that number is likely to increase to six very soon; however, further investigations are necessary. Much more work is still needed before we fully understand the wide spectrum of clinical signs and symptoms of HFRS as well as the pathogenicity of the different viruses in the hantavirus genus of the Bunyaviridae family. HFRS is difficult to diagnose on clinical grounds alone and serological evidence is often needed. A fourfold rise in IgG antibody titer in a 1-week interval, and the presence of the IgM type of antibodies against hantaviruses are good evidence for an acute hantavirus infection. Physicians should be alert for HFRS each time they deal with patients with acute febrile flu-like illness, renal failure of unknown origin and sometimes hepatic dysfunction. Especially the mild form of HFRS is difficult to diagnose. Acute onset, headache, fever, increased serum creatinine, proteinuria and polyuria are signs and symptoms compatible with a mild form of HFRS. Differential diagnosis should be considered for the following diseases in the endemic areas of HFRS: acute renal failure, hemorrhagic scarlet fever, acute abdomen, leptospirosis, scrub typhus, murine typhus, spotted fevers, non-A, non-B hepatitis, Colorado tick fever, septicemia, dengue, heartstroke and DIC. Treatment of HFRS is mainly supportive. Recently, however, treatment of HFRS patients with ribavirin in China and Korea, within 7 days after onset of fever, resulted in a reduced mortality as well as shortened course of illness.

The authors studied clinical and biological data occurring in 165 patients observed during 23 years and afflicted with polyarteritis nodosa. Hypertension was present in 52 patients (31.5%) and seven of them suffered from malignant hypertension (4%). Mean age of patients (6 male, 1 female), with malignant hypertension was 38 +/- years old. Mean follow up was 49 +/- 28 months including 26 +/- 21 months after discontinuation of treatment of polyarteritis nodosa. Malignant hypertension occurred during the first year of evolution of polyarteritis nodosa. Renal insufficiency was present in 5 of 7 patients. Proteinuria was greater than 1 gr/d in 4 cases. Renal arteriography was performed in 6 patients and showed in every case renal ischemia and microaneurysms in five. In 4 patients measurements of plasma renin activity and of aldosterone were obtained. A stimulation of those hormones was demonstrated. Some symptoms of polyarteritis nodosa were present with a high incidence in case of malignant hypertension: digestive signs (6/7), orchitis (3/6). HBs antigen was present in 6 cases and hepatitis in 5. Captopril was effective in every case, alone or associated with other treatments. Follow up of hypertension went from 8 months to 4 years. At present time 6 patients are alive and one is lost of follow up. A treatment is necessary in 6 of 7 patients. Creatininemia is greater than 300 micromol/l in 4 patients. A successful kidney transplantation was performed in one case. Our study shows a close relation between malignant hypertension observed in polyarteritis nodosa, vascular nephropathy, digestive and urologic signs. Hepatitis B virus could be responsible of those manifestations.
