Investigations included 52 drug-addicts with asymptomatic HIV virus infection. 8 of them suffered some years ago, from virus hepatitis of type B. Physical examinations did not reveal in examined persons any deviations from normal condition except for hepatomegaly. Results of liver biochemical investigations remained within normal limits. In each of them one confirmed presence of serological markers of HBV infection and in 35 of them of HCV and in 5 of them in parallel HDV. In all the examined persons one carried out liver biopsy and routine morphological examinations. In every case one disclosed a liver injury of drug-induced type. Further, in 31 examined persons one detected a coexistence of chronic, active inflammatory process of liver hepatitis minimal--17 hepatitis chronica persistent--12 hepatitis chronica aggressivE--1 cirrhosis hepatis--1 and in four of them changes of the type fibrosis periportal. In HIV infected drug-addicts it comes about to clinically asymptomatic, chronic hepatitis coexisting with morphological changes of drug-induced type liver.

Hepatoma is a rare disease in Natal Indians. It occurs in male patients in the fifth decade. They have no history of alcohol intake. The main presenting feature is abdominal pain, weight loss and hepatomegaly. Blood tests reveal a raised alkaline phosphatase, hypoalbuminaemia, hypergammaglobulinaemia and markedly raised gamma glutamyl transferase. The tumour is a single large expanding mass in the right lobe. The patient usually presents in a late stage of the illness and shows a progressive downhill course. Hepatitis B virus infection is emerging as the likeliest carcinogen.

A 3.5 year old girl presented with a history of high fever, rigors, and mild cough for 1 week. Physical examination revealed normal chest findings but gross hepatomegaly was detected. Liver function tests were abnormal and indicated biliary obstruction. Ultrasonography revealed a distended gall-bladder with increased wall thickness up to 0.6 cm. The diagnosis of primary Epstein-Barr viral infection was eventually made by specific serological study. The patient's fever subsided 2 weeks later and her liver function tests returned to normal 1 month later. Abdominal ultrasonography at this time was normal.

Liver disease, although usually asymptomatic, is a frequent accompaniment of AIDS. Hepatomegaly and macrosteatosis are prevalent but non-specific findings. Evidence of remote hepatitis B virus infection is extremely common; however, the HBsAg carrier state, chronic active hepatitis, or cirrhosis occur no more frequently in AIDS patients than in the general population. Opportunistic intrahepatic infections (such as MAI, fungi, and CMV) or neoplasms (such as lymphoma or KS) usually reflect a disseminated process; liver involvement generally does not directly cause morbidity or result in death. Although biochemical liver tests are commonly elevated in the AIDS population, alkaline phosphatase has proved to be the most specific enzyme for infiltrative processes. Percutaneous liver biopsy has a high diagnostic yield, although the treatment options are currently limited. Acalculous cholecystitis and biliary tract obstruction have been recently described and probably result from CMV and/or cryptosporidial infection. Radiologic features of papillary stenosis and/or sclerosing cholangitis have been demonstrated. In contrast to hepatic parenchymal disease, these entities may be amenable to surgical or endoscopic therapeutic maneuvers.

Eleven patients of Chinese origin experienced spontaneous reactivation of chronic active hepatitis B. Eight HBsAg-positive patients were followed for an average of 15 months prior to, while three others presented during reactivation. Fatigue, hepatomegaly and jaundice were frequent findings. Elevation of both serum ALT (average = 1,212 units per liter) and hepatitis B virus DNA levels were noted in all patients, and reactivation lasted an average of 4.4 months. During resolution, clinical symptoms abated, serum ALT levels reverted toward normal, and in nine patients, the hepatitis B virus DNA values became undetectable. All patients lacked evidence for acute hepatitis A, Epstein-Barr Virus, cytomegalovirus or hepatitis delta virus infection. Histologic findings of liver tissue from eight patients showed piecemeal necrosis and fibrosis. Within the parenchyma, varying degrees of hepatocytolysis with cuffing, perivenular necrosis and acidophilic bodies were noted. Ground-glass cells and regenerative changes also were observed. Cirrhosis was not present in any of the liver biopsies. These findings suggest that spontaneous reactivation of hepatitis B occurs in heterosexual patients with chronic active hepatitis B and contributes to chronic inflammation and to the progression of their liver disease.

A 2-year-old boy had acute fever, malaise, and somnolence with hepatomegaly, increased blood ammonia content (338 microM), high SGOT, low blood glucose content, and mild acidosis. A liver biopsy showed diffuse accumulation of lipid droplets in swollen hepatocytes, and abnormal urinary metabolites included beta-hydroxy-beta-methyl glutarate (HMG), beta-methylglutaconate, beta-hydroxyisovalerate, and beta-methylglutaric and glutaric acids. In cultured skin fibroblasts and liver, beta-hydroxy-beta-methyl glutaryl CoA lyase activity was about 10% of normal. Therefore, a genetic deficiency of HMGCoA lyase activity can cause a clinical syndrome similar to that of Reye syndrome when the patient is stressed by an acute viral infection.

Hemopoietic stem cells were studied in the marrow, spleen and liver of individual, FV-P infected DBA/2 mice. At more than 17 days after infection there was a tendency for CFU-EI numbers in the spleen to be reduced compared to earlier intervals after virus infection; CFU-EI numbers in the marrow were low. At the same time all hemopoietic stem cells (CFU-S, CFU-C, BFU-E and CFU-EI) could be found in the enlarged liver. The migration of stem cells from the marrow to the spleen and further to the liver is discussed.

This study was carried out to demonstrate hepatitis "E" virus antibodies (IgG) among individuals living in different rural areas. The study included 200 individuals. One hundred were suffering from S. mansoni as confirmed by stool egg count, rectal snip, abdominal ultrasound and liver biopsy. The second hundred (Group II) were parasite-free individuals serving as normal control. The main symptoms of group I were dyspepsia, fatigue, dysentery, bleeding per rectum and hepatomegaly. There was no significant difference in the transaminase levels (SGPT and SGOT) between both groups. The prevalence of HEV-ab (ab (IgM) among group I was 31% and group II, 14% with a highly significant increase in group I. There was no correlation between the number of egg count in stools and HEV infectivity. Thus, the prevalence of HEV was higher in the rural areas and in schistosomiasis patients in particular, due to low sociohygienic conditions under which the patients are living. Also schistosomiasis may play a role in virus infection by altering the immune system.

The original TORCH complex described clinically similar congenital infections caused by Toxoplasma gondii, rubella virus, cytomegalovirus, and herpes simplex virus, types 1 and 2. Cutaneous manifestations, including petechiae, purpura, jaundice, and dermal erythropoiesis, are commonly seen in toxoplasmosis, rubella, and cytomegalovirus infections. In herpes simplex virus infections, 80% of symptomatic infants show single or grouped cutaneous vesicles, oral ulcers, or conjunctivitis. Extracutaneous signs and symptoms are variable and can be severe. Significant clinical signs in congenital toxoplasmosis include diffuse intracerebral calcification, chorioretinitis, and microcephaly; congenital rubella can result in deafness, congenital heart disease, retinopathy, and brain calcification. Cytomegalic inclusion disease can include hepatomegaly, splenomegaly, paraventricular calcification, and intrauterine growth retardation. Localized or disseminated congenital herpes virus infection often involves the central nervous system and the eye. Diagnosis is confirmed by culture and identification of species-specific immunoglobulin M within the first 2 weeks of life. Histological examination contributes to the diagnosis in herpes simplex virus infection. Treatment for toxoplasmosis includes pyrimethamine with sulfadiazine or trisulfapyrimidine; congenital herpes simplex virus infection is treated with acyclovir. No specific therapy for congenital rubella or cytomegalovirus infections has been established, and so treatment is primarily supportive.

A study of the clinical profile of 59 patients who presented with hepatitis A virus infection showed that dark urine, fatigue, gastrointestinal complaints, and fever were the most common presenting symptoms. The most frequent physical findings were hepatomegaly and jaundice. The mean presenting laboratory tests included total bilirubin of 5 mg/dL, alkaline phosphatase of 269 units/L, and serum aspartate aminotransferase and alanine aminotransferase levels of 1442 mIU/mL and 1952 mIU/mL, respectively. Atypical manifestations included relapse, cholestasis, rash, and arthralgia. Two patients presented with hepatitis A and concomitant type I autoimmune chronic hepatitis, and both required immunosuppressive therapy. Five patients who presented with hepatitis A were pregnant, and during follow-up, none of their infants developed elevated serum transaminase values or had detectable IgM anti-HAV antibody. All 59 patients experienced complete clinical and biochemical recovery within 6 months after onset of illness.
