Effect of malnutrition during different periods on the small intestine of the rat.

Parameters of nutritional and small intestinal status were studied in 3 groups of rats which had been subjected to malnutrition during different periods (pre- and postnatal, postweaning and adulthood). Malnutrition was induced by restriction of feeds (50% of controls). Compared with controls, malnourished rats from all 3 groups had reduced body weight and length, thoracic diameters, small intestinal weight, length and diameters, small intestinal mucosal weight, total mucosal DNA and protein/DNA ratios. However, there was no difference in DNA contents between malnourished rats and corresponding controls, indicating no changes in cell number (hypotrophic). Prenatally malnourished rats had reduced specific activities of lactase, sucrase and maltase. But in other malnourished groups, the activities of these enzymes were higher compared with corresponding controls. Prenatally malnourished rats had the lowest percentage of control values in all parameters measured compared with the other malnourished rats.

Diarrhoeal problems in Southeast Asia.

Diarrhoea up till now is still a major problem in Southeast Asia with high morbidity and mortality, particularly among children under 5 years of age, with the peak in children between 6 - 24 months. In Indonesia, in 1981, it was estimated that there are 60 million episodes with 300,000 - 500,000 deaths. In the Philippines, diarrhoea ranks as a second cause of morbidity (600 per 100,000 in 1974) and second cause of infant mortality (5 per 1,000 in 1974). In Thailand, in 1980, the morbidity rate was 524 per 100,000 and the mortality rate 14 per 100,000. In Malaysia, in 1976, diarrhoea was still ranking number 5 (3.1%) as a cause of total admission and number 9 (2.2%) as a cause of total deaths. In Singapore, diarrhoea still ranks number 3 as a cause of deaths (4% of total deaths). In Bangladesh, the overall attack rates imply a prevalence of 2.0% for the entire population, with the highest for under 5 groups i.e. 4.1%. The diarrhoea episode in rural population is 85.4%, 39% of them are children under 5. The most common enteropathogens found in all countries are rotavirus followed by Enterotoxigenic E. coli, Vibrio spp., Salmonella spp., Shigella spp. and Campylobacter. Malnutrition and decline of giving breast-feeding play an important role in causing high morbidity, besides socio-economic, socio-cultural and poor environmental sanitation.

Salmonellosis in Indonesia: phage-type of Salmonella oranienburg obtained from hospitalized patients in Jakarta, Indonesia.

During a survey in Jakarta, Indonesia, 158 cultures of Salmonella oranienburg, consisting of two phage types, were obtained from 150 hospitalized patients with diarrhoea. Phage type I, though found notably in young children, was found in all age groups while phage type II was found almost exclusively in young children aged 0-7 years. Phage type I may produce a more severe clinical picture affecting all age groups alike, while phage type II may result in hospitalization of only the very young, who are more susceptible to dehydration. Phage type I was significantly more resistant than phage type II to the individual antibiotics: tetracycline, chloramphenicol, kanamycin and neomycin. However, there was no difference in their respective antibiotic resistance patterns as measured by disk and MIC assay. All cultures were sensitive to gentamicin and trimethoprim-sulphamethoxazole 1:19.

Reduction by aspirin of intestinal fluid-loss in acute childhood gastroenteritis.

Soluble aspirin was given by mouth in therapeutic doses in a double-blind trial to malnourished infants and young children with gastroenteritis and dehydration. Faecal fluid-losses were reduced and weight-grain was enhanced in the group given aspirin. These effects were statistically significant when compared with those obtained with a placebo preparation and in a group of patients given supportive therapy but no specific drug treatment. The results suggest that aspirin may be useful in reducing intestinal fluid-loss in childhood gastroenteritis. Before the widespread use of aspirin can be recommended, its effects in patients not under hospital supervision must be determined.

Human salmonella carriers in a tropical urban environment.

Salmonella sp. were isolated from rectal swab specimens from 39 to 464 (8.4%) of apparently healthy adults and children in central Jakarta, Indonesia. A wide variety of species of Salmonella were found with S. oranienburg predominating. Most of the S. oranienburg isolated were resistant to a wide range of antibiotics, probably because of their previous widespread and inappropriate administration. The yield of carriers identified increased significantly with the use of double enrichment procedures. This study emphasizes the importance of high rates of carriage of Salmonella sp. as potential causes of diarrhoeal disease in overcrowded, unhygienic cities in the tropics.

Defective Candida killing in childhood malnutrition.

This study shows that malnourished children have impaired candidacidal activity of leucocytes, a finding which runs parallel to the higher rates of isolation of Candida sp. from throat secretions. In well nournished subjects the mean candidacidal ability was 44.5% in the moderately undernourished group it was 17.6%, and in the severely malnourished group it was 13.7%. This impaired candidacidal capacity may be important in the establishment of large numbers of Candida sp. which are commonly found in the upper intestine and in the pathogenesis of diarrhoea in children with malnutrition.

Dengue with haemorrhage and shock in Jakarta, Indonesia.

Pediatric patients with fever and haemorrhage were studied in Jakarta, Indonesia between May 1973 and January 1974. Eighty-one of 104 demonstrated unequivocable evidence of dengue with clinical findings similar to those reported associated with dengue haemorrhagic fever in Thailand. The majority of patients had extremely high antibody titers against dengue measured by both hemagglutination-inhibition and by plaque reduction neutralization tests and all four types of dengue virus were isolated. Eight of the patients died.

Use of a simple duodenal capsule to study upper intestinal microflora.

The upper intestinal microflora was studied in 10 malnourished Indonesian children using the paediatric Enterotest Capsules. Trophozoites of Giardia lamblia were found in 2 specimens, profuse fungal mycelia in 3, and ascaris worms and eggs in 1. In 9 patients an abnormally profuse small intestinal bacterial flora was found. Provided precautions are taken to exclude artefactual contamination of the line on its withdrawal, this is a safe and simple method for studying the upper gut flora which could be applied to field conditions since it does not require radiological facilities.

The stomach in malnutrition.

Basal gastric acid output was reduced in 9 out of 14 infants and young children with malnutrition compared with 21 age-matched controls. In all the patients the response of the gastric mucosa to stimulation by pentagastrin was impaired, and gastritis of variable severity was present in 8 out of the 9 patients in who biopsies were performed. Impaired gastric acid secretion probably contributes towards bacterial overgrowth and diarrhoeal diseases in malnourished children.

Serum and small intestinal immunoglobulin levels in undernourished children.

Intestinal immunoglobulin levels were quantitated in undernourished Indonesian children with enteric infections and normally nourished Indonesians with and without enteric infections. These were compared to the same parameters in Australian Aboriginal children (also suffering undernutrition) and normal Caucasian children. Children with enteric infections displayed equally elevated levels of intestinal immunoglobulin irrespective of their nutritional status. Intestinal infections appeared to elevate IgG levels more than secretory IgA levels in the age group examined. However, it appeared likely that some of the EgG was serum-derived whereas the IgA appeared to be locally produced. There was no apparent deficiency in the capacity of undernourished children to manufacture and secrete immunoglobulin in the gut.

Febrile illnesses resulting in hospital admission: a bacteriological and serological study in Jakarta, Indonesia.

A study of 741 Indonesian patients with fever was carried out in order to determine what serious febrile illnesses are prevalent in Jakarta. All patients were hospitalized primarily because of fever and were studied by bacteriological and serological methods. Bacteremia due to Salmonella typhi (150 cases), S. enteritidis (36 cases), or both (2 cases) was common in both children and adults. One S. enteritidis isolate was chloramphenicol resistant. Serological evidence of Salmonella infection was found in 130 additional cases without bacteremia. Serological evidence of arbovirus infection (94 cases) was common in children. Malaria was found in 12 adults, most of whom were probably infected outside Jakarta. Little serological evidence was found for rickettsial, leptospiral, Brucella, Toxoplasma gondii or a number of other infections. Clinical signs and symptoms in the febrile patients studed were generally nonspecific, and laboratory results reported were very helpful in establishing more accurate diagnoses.
