For the purpose of experimental infection with human hepatitis B virus, 14 chimpanzees (Pan troglodytes) were delivered to the Division of Animal Research, Faculty of Medicine, University of Tokyo, Tokyo. These chimps, 11 males and 3 females, born in the West Africa, had been reared for two to six months. Several days after delivery, they were anesthetized with Ketalar in order to make clinical, bacteriological and parasitological examinations; It was found that one of them was in malnutrition, and that another had dislocation of the shoulder joint and the associating abscess. All of them were negative for tuberculin test. In the bacteriological examination, Shigella sonnei was detected in the feces from one of them. Mycoplasma sp. was detected in the materials from the oral cavity of four head. As intestinal parasites, Ascaris sp. were detected in two head, Enterobius vermicularis in eight, Strongloides sp. in two, Oesophagostomum sp. in nine, tape worms in four, and Entamoeba coli in twelve. Microfilaria as blood parasite was detected in 11 of them. The laboratory used for the experimental infection was a room occupying about 42 m2, which had been built by renovating a part of our division building. Each of the cages used for rearing the chimps was contained in the isolation box made of stainless steel. The contaminated air in the isolation box was discharged forcedly into the exhausting duct with a fan, and further passed through the HEPA filter and the Miraceram honeycomb heater, and was then conducted to the already existing ventilation duct of the division building. Each chimp was fed on a ration of 200-350 g of the imported "Purina Monkey Chow 25" and also one grapefruit and one banana daily for the supply of vitamin C. The chimps weighed 16.1 kg on the average on delivery, but gained an average weight of 4.2 kg during the following four months.

The maternal and fetal outcomes of 50 pregnancies complicated by acute viral hepatitis were examined. Twenty (40%) cases were due to type B hepatitis virus. The clinical course of the maternal hepatitis was unaffected by the pregnant state. Maternal hepatitis (type B or nontype B) had no effect on the incidence of congenital malformations, stillbirths, abortions, or intrauterine malnutrition; it did increase the incidence of prematurity (type B 31.6%; nontype B 25%; overall 27.6%) over that seen in the general delivery population (10 to 11%). Eight mothers acquired acute type B hepatitis during the third trimester; two of their infants (25%) were found to be chronic asymptomatic carriers of hepatitis B surface antigen and to have mild, persistent elevations of SGOT for up to 45 months.

The biological literature contains many examples of mutual influences between different species of parasites, especially with respect to concomitant helminth infections. Several situations are known in which the association of infection by Schistosoma mansoni with other pathogens in the same host results in a type of disease which differs from the simple summation of the individual effects of each infection. The present study concerns concomitant infections involving S. mansoni and enterobacteriaceae; S. mansoni and other helminths such as Ascaris lumbricoides, Ancylostomids, Toxocara canis and species of the genus Hymenolepis; S. mansoni and different protozoa such as Trypanosoma cruzi, T. brucei, Toxoplasma gondii and Plasmodium berghei. The interaction between hepatitis B virus and S. mansoni, leading to prolonged viremia and worsening of liver damage, is also discussed. The paper also treats the simultaneous occurrence of schistosomiasis and other aggravating factors such as malnutrition and neoplasias which may alter the host's response to the trematode.

As reported for other chronic liver diseases, hepatitis B virus (HBV) chronic infection might result in malnutrition. In order to establish whether this disease could be responsible of malnutrition and hence influence growth, 75 children, chronically infected with HBV, have been followed up for 4 years. Thirty-one of them had chronic active hepatitis (CAH), 25 chronic persistent hepatitis (CPH), 14 chronic lobular hepatitis (CLH), and five cirrhosis (three active, two inactive). The nutritional status was evaluated every 12 months, with careful physical and laboratory examinations. General nutritional status was estimated according to Waterlow criteria (13, 14). At our first observation, 50 children were following a balanced diet with a caloric intake adequate for age and weight, whereas 25 were on a low-fat diet, begun in the belief of its therapeutic value. For seven patients of this second group, the caloric intake was below the daily requirement. The latter group showed a growth failure in weight when they were first seen at our center and gained weight when the dietary intake was normalized. However, no biochemical feature of malnutrition was observed in all the 75 children. At the end of the follow-up period, the nutritional status was satisfactory for all of them.

We report the development of severe hepatotoxicity in a patient on zidovudine therapy who received 3.3 g of acetaminophen in less than 36 hours. Three days later, the patient's serum aspartate aminotransferase level was 5,724 U/L, alanine aminotransferase was 3,124 U/L, lactate dehydrogenase was 12,675 U/L, alkaline phosphatase was 84 U/L, and total bilirubin was 20 mumol/L. These values substantially improved over the ensuing 4 days. Serologic results for hepatitis B, hepatitis A, and cytomegalovirus were all negative. The pattern and time sequence of transaminase elevation in this patient are consistent with acute acetaminophen hepatotoxicity, especially since zidovudine-induced hepatotoxicity is described as producing cholestasis rather than acute hepatitis. We hypothesize that our patient's susceptibility to acetaminophen-dependent hepatotoxicity may have been augmented by competitive utilization of glucuronidation by other drugs such as zidovudine and/or trimethoprim-sulfamethoxazole with subsequent increased cytochrome P450-dependent metabolism of acetaminophen. Additionally, due to malnutrition and/or to human immunodeficiency virus infection per se, our patient may have had decreased hepatic reserves of glutathione with which to conjugate the toxic acetaminophen product of the P450 system. Although severe acetaminophen-associated hepatotoxicity has not previously been reported in patients receiving zidovudine, we suggest that clinicians be aware of this potential interaction and counsel malnourished patients, especially those with concomitant hepatic disease, to exercise caution when taking both these medications.

This article has provided an overview of the effects of HIV on renal function. Most transmission of the virus occurs by sexual, blood, and perinatal contact. CD-4 positive cells, especially those that are integral components of the immune system, serve as the reservoir for the reproduction of the virus. The resulting effect is destruction of the immune system with eventual multisystem failure and death. Renal complications arise from several factors, notably the compounding effects of chronic dehydration, malnutrition, infection, and use of nephrotic agents. Acute renal complication can be reversible with prompt assessment, and management directed at maintaining hydration, preventing sepsis, and carefully monitoring drugs. A chronic, irreversible renal disease in HIV is due, in large part, to a syndrome known as AIDS nephropathy, characterized by glomerular sclerosis and nephrotic-type symptoms, which ultimately lead to the need for dialysis. Aids nephropathy is seen most often in intravenous drug users, Haitians, and blacks with HIV. End-stage disease complicates the course of HIV and contributes to early mortality. A small, but significant number of renal patients acquires HIV infection as a result of multiple blood transfusions or through organ donation. Concentrated exposure to blood and body fluid during dialysis necessitates implementation of meticulous infection control procedures to protect both staff and patients. Guidelines by the CDC suggest that universal precautions adequate to prevent the spread of hepatitis B will suffice for HIV as well. HIV infection presents special challenges for those involved with renal management. Prevention and management of renal complication are made possible by thorough understanding of the complex network and interaction of the disease process.

Between January 1985 and December 1987, seventy-five children of intravenous heroin-addicted parents (one or both) were studied. Their ages ranged from 4 days to 14 years. All patients had suffered from several pediatric diseases. Three major types of problems were found among the children studied: infectious diseases, nutritional diseases, and parental neglect and/or disinterest. The most common diagnoses at discharge were gastroenteritis (24%), pneumonia (21%), malnutrition (17%), upper airway infectious diseases (13%), septicemia (12%), child abuse (4%), acquired immunodeficiency syndrome (3%), and other infectious diseases (24%). Their parents reported hepatitis B virus infection, acquired immunodeficiency syndrome (AIDS), and alcoholism. The unemployment rate among the fathers was 37%. Sixteen percent of mothers were prostitutes. There was an imprisonment record of 19% for mothers and fathers combined. A multidisciplinary approach for this group of children would make prevention possible and care less expensive.

Little information is presently available about health issues associated with intercountry adoptions. This research starts to fill this gap by surveying the health problems of 200 children from India adopted by 166 Oregon families during the period 1978-1987. Parents' responses to a mail questionnaire revealed that at least 37.5% of the children were premature. The children's birth weights and birth lengths were 3 to 4 SDs below WHO norms, and almost all the children's weights and heights by age, at time of arrival in the United States were below WHO's 50th percentile value. Feeding problems were frequent (35.0%), as were salmonella (30.5%), malnutrition (22.0%), anemia (18.5%), and developmental delays (18.0%). Many children were not tested for communicable diseases endemic to India such as hepatitis B, tuberculosis and salmonellosis. Many diseases and health problems were unanticipated by parents on the basis of medical reports received from India, and parents expressed a need for greater support and better resources in dealing with these health problems.

Diarrhea, pneumonia, and malnutrition account for most of mortality and morbidity in children in developing countries. The Expanded Program of Immunization (EPI) is making progress with more than 50% of children under the age of 1 year receiving vaccination against the 6 EPI-listed diseases. The eradication of poliomyelitis by 2000 is realistic, so that the world could be smallpox- and polio-free by the 21st century. In July-August 1988 a cholera epidemic erupted in Delhi, India in which several hundreds died. The combined whole cell and toxin-B subunit oral vaccine against cholera has shown a decrease in protection from around 75-80% at the end of 6 months to around 60% at the end of 2 years. Typhoid fever affecting close to 8 million people in Asia has been treated with the improved formulation of TY21A vaccine and with the Vi polysaccharide capsular surface antigen in encouraging trials in Nepal. Co-trimoxazole has reduced child mortality caused by acute lower respiratory tract infections at the community level. 3 oral antirabies vaccines have been found safe, and oral baits have been effective. Chloroquine-resistant Plasmodium falciparum malaria is a major problem in may Asian countries involving sulfadoxine-pyrimethamine combinations as well. Lymphatic filariasis is expressed clinically as elephantiasis. More than 90 million people are believed to be infected. Ivermectin in a single dose as low as 25 mcg/kg of body weight was shown to be microfilaricidal in lymphatic filariasis. Allopurinol riboside is effective against visceral leishmaniasis or kala-azar. Leprosy and tuberculosis continue to be major health problems in Asia. There have been encouraging advances in immunization against cancers of the tropics, such as hepatitis B and primary carcinoma of the liver, the human papilloma virus and cancer of the uterine cervix, the Epstein-Barr virus and Burkitt's lymphoma, and nasopharyngeal carcinoma.

A survey of Hepatitis B virus (HBV) carrier state of paid and voluntary blood donors in and around the city of Calcutta has been carried out. HBV carrier state is higher in paid donors (5.84%) than voluntary donors (1.79%). The nutritional status of paid donors as assessed by serum protein, immunoglobulin and cholesterol shows evidence of malnutrition and chronic infection. The socio-economic status of the prospective blood donors has an important bearing on the persistence of carrier state for HBV.
