After a review of the literature on epidemiological, serological and histopathological data concerning so-called "Amazon Black Fever" (Labrea disease), an experimental model of morphological reproduction of the disease is presented. The model is based on the probable causal synergism of Labrea hepatitis, i.e., viral injury plus protein-caloric malnutrition. Mice infected with the Oriboca arbovirus presented classic yellow-fever-like lesions of the liver, with a few malnourished animals showing the characteristic morular changes of the human disease.

To characterize type and age distribution of malnutrition and to determine the usefulness of anthropometric indices in children with chronic liver disease (CLD), 56 children (aged 1 mo-10 y) with CLD underwent anthropometric evaluation when they were clinically stable. Mean-height Z score was depressed, whereas mean-weight Z score was closer to normal and mean-weight/height Z score was normal in patients with extrahepatic biliary atresia, idiopathic neonatal hepatitis, and other liver disorders. Patients with arteriohepatic dysplasia showed more severe depression of all three variables. In all patients, triceps skinfold (TSF) thickness Z scores were significantly more depressed than were weight/height Z scores. Depressions of midarm-circumference and midarm-muscle-area Z scores were intermediate. Mean-head-circumference Z score was depressed in children aged less than 24 mo. We conclude that acute (wasting) and chronic (stunting) malnutrition are common in childhood CLD and that weight/height values underestimate the degree of acute malnutrition compared with TSF thickness, most likely because of the inflated patient weight caused by organomegaly.

Liver disease in pregnancy is uncommon, acute viral hepatitis being the most frequent. The latter has a normal prognosis in pregnancy, with the possible exception of NANB hepatitis in India and North Africa. Immunization of neonates born of mothers suffering from acute or chronic HBV is essential and effective. Acute fatty liver of pregnancy has a better prognosis than previously thought, perhaps due to diagnosis of milder cases or improved intensive care. Its etiology is still unknown, but metabolic stress may be important. The confusion and overlap of AFLP, the HELLP syndrome, and liver disease of eclampsia suggest common etiological factors. Urgent delivery of the fetus is recommended in AFLP. The related condition of acute liver rupture may be diagnosed by ultrasound. Successful conservative management has been reported. Estrogens are involved in the pathophysiology of ICP, but this does not explain the profound racial differences in incidence. The nature of the sensitivity to estrogens is not understood, although reduced membrane fluidity, which may be counteracted by S-adenosyl-L-methionine, is one possible explanation. The increased fetal loss associated with ICP suggests that treatment should be more energetic than hitherto. In the worst affected individuals, fetal malnutrition secondary to maternal steatorrhea may be an important factor. In general, patients with chronic liver disease have increased maternal and particularly fetal mortality.

Nutritional assessment factors (including dietary history, anthropometric and biochemical measurements, and evaluation of immunocompetence) were retrospectively reviewed in 74 patients undergoing an initial liver transplantation procedure. The patients were subdivided into four categories on the basis of type of liver disease: chronic active hepatitis (N = 24), primary sclerosing cholangitis (N = 22), primary biliary cirrhosis (N = 20), and acute or subacute hepatitis (N = 8). Our nutritional assessment data indicated that malnutrition was present preoperatively in all liver transplantation groups but that each group had distinct characteristics. The group with primary biliary cirrhosis seemed to have the best hepatic synthetic function despite extreme wasting of muscle and fat. On the basis of all criteria, the group with acute hepatitis was the most malnourished of the various disease groups. Aggressive nutritional support, which includes adequate intake of nutrients and supplementation of vitamins and trace minerals, should be encouraged for all potential liver transplant patients.

Alterations of the gallbladder wall is a well known sonographic sign of acute cholecystitis. But thickening of the gallbladder wall is also found in patients without intrinsic gallbladder disease. We present our experience on this regard in patients with cirrhosis, acute viral hepatitis, infectious mononucleosis, halothane hepatitis, fulminant hepatic failure, malaria due to plasmodium falciparum, heart failure, severe malnutrition due to gastric obstruction, septicemia, pyogenic hepatic abscess, amoebic hepatic abscess and in a 14 years old patient with fracture of the skull-acute anemia-shock. Most of these diseases affected the liver directly or indirectly. Knowledge of these alterations of the gallbladder wall in these circumstances are important in order to avoid a the erroneous diagnosis of acute cholecystitis.

Suckling BALB-c mice, subjected to nutritional deprivation in artificially expanded litters (18 to 20 pups), were compared to normally nourished pups (7-9 per litter) in a series of experiments designed to provide data on morphologic and functional alterations of the small intestine during malnutrition and infection. The effects of protein calorie malnutrition (PCM) on the viral replication pattern and severity of clinical disease were examined in suckling mice infected with murine rotavirus (MRV). The infection in nutritionally deprived animals was characterized by a significant decrease in the minimal infectious dose and in the incubation period for the onset of diarrhea as well as increased severity of disease when compared to well nourished controls. Rotavirus-specific antibody, administered orally prior to virus inoculation, significantly reduced MRV replication in both groups but most strikingly in malnourished animals. Additional studies of the uptake of a macromolecule [ovalbumin (OVA)] following oral administration to experimental and control groups showed more rapid and complete absorption in the malnourished animals. Infection further enhanced the uptake of OVA, suggesting that both PCM and rotavirus infection alter the permeability of the small intestine. An unexpected observation of rotavirus-associated hepatitis in CB-17scid mice was also made in nearly 40% of malnourished mice inoculated with 10(6) PFU of Rhesus rotavirus (RRV). Mice with PCM exhibited a susceptibility to hepatitis between SCID mice (80%) and immunologically normal mice (18%). While these data are not sufficient to confirm a nutritionally-mediated immunoincompetence, they do suggest that either loss of immune competence and/or increased gut permeability in malnourished animals may allow a more severe homologous rotavirus infection as well as extraintestinal spread of heterologous rotavirus.

Forty-seven Gabonese children with tuberculosis either limited to the lung or associated with other localizations were treated with isoniazid-rifampin (INH + RIF). They had liver tests done during the first 6 months of treatment. In 30 patients (63.8%) there was an increase in aminotransferase levels [over 100 UI/l in 14 (29.2%)]. The main factors increasing the risk of hepatic toxicity was a high dosage of INH and overall malnutrition. In fact, the weights of patients presenting with signs of hepatic toxicity were significantly lower than those in children who had no alterations of liver function. 68% of the severely malnourished (marasmus of kwashiorkor) presented with high ALAT or ASAT levels during treatment. The eventual role of the chronic HBV carrier state is discussed as 2 children presented with a chronic form of hepatitis at the time the treatment was initiated.

The authors collected 41 cases of cirrhosis in native Tibetans with pathological verification. It is found that 60.98% of the cases were alcoholic cirrhosis, with an incidence significantly higher than that of 7.6% reported in the inland (P less than 0.01). 74.19% and 20% of the cirrhosis in male and female patients respectively were alcoholic, while 50% of the cirrhosis in the female were due to malnutrition. Among the Tibetan cirrhotics 12.2% was due to hepatitis and 4.88% each to hydatid disease and tuberculosis. The average age of these cirrhotics was 47.05. The frequent occurring age was between 41-50 (about 41.46%). The Tibetan cirrhosis in peasants and herdsmen were 51.28%. At the first admission, 84.49% got jaundice and 90.2% got ascites. These percentages were higher respectively than 43.2% and 50.5% from the Lanzou report (P less than 0.01). Ascites was serious, portal vein expanded, but splenomegaly were merely 17.07% (normal were 82.93%). These spleens expanded just a little, macrosplenopathy was not found.

This review article is mainly concerned with the incidence and pathogenesis of alcohol-induced liver diseases. Clinically the most relevant symptom is a hepatomegaly. During the course of the disease there is to state progression to alcoholic hepatitis with increasing jaundice. The laboratory values show different patterns; severe courses develop progression to a fulminant hepatitis. The diagnostic approach includes exact patient's medical history, clinical and laboratory investigations, followed by a step-wise diagnostic procedure including histology. Therapeutically the main approach is a diet, in case of malnutrition substitution of vitamins and only rarely the need of corticosteroids and/or anabolic steroids. Prognosis and long-term course of alcoholic-induced liver disease depend mainly on the severity of the disease and the consequent alcohol-free diet.

Causes of maternal mortality were investigated in Addis Ababa, Ethiopia, from September 1981 to September 1983. Viral hepatitis ranked third among the leading causes of maternal mortality behind septic abortion and puerperal sepsis. There were 26 deaths from viral hepatitis during the 2-year study period for a hospital maternal mortality rate of 91.0 per 100,000 live births. Although 30% of women who died of all maternal causes received antenatal care in Addis Ababa, only 13% of women who died from viral hepatitis in our hospital study received antenatal care. Low socio-economic status (SES) has been shown to be associated with low antenatal care utilization and with an increased risk of protein malnutrition. Malnutrition is considered a predisposing factor for liver damage. Suggestions for reducing hepatitis transmission and maternal mortality through education, better hygiene, and improved sanitation are discussed.
