A total of 186 infants suffering from dehydration due to acute diarrhea were studied and divided into two groups: 84 children were placed in group A and received the oral rehydration solution (ORS) recommended by the World Health Organization (WHO), know as ORS-90 and those placed in group B were given an ORS with 60 and 90 mmol/L of sodium and glucose, respectively, with an osmolality of 240 mOsm/kg (ORS-60). Seven patients from group A (8.3%) and two from group B (2.5%) could not be orally rehydrated and required intravenous rehydration. The children were divided according to their weight for their age into eutrophics, grade I malnutrition (10 to 25% deficit), grade II (26 to 40% deficit) and grade III (more than 40% deficit). In those patients who evolved favorably, the average rehydration time was 4.5 to 5.3 hours, independently from their nutritional state. In the same way, no important variations were seen in the average sodium and potassium serum levels once the dehydration was corrected, in either of the groups. Yet, both groups showed a persistence in hypokalemia and hyperkalemia seen when admitted, once the dehydration was corrected, demonstrating that the short time needed for the correction of the dehydration was insufficient to completely corrected the changes in serum potassium. Closer studies must be conducted on the hydric balance to adequately demonstrate if the new ORS-60 induces lesser losses through vomiting and feces when compared to the ORS-90 recommended by the WHO.

A protocol of nutritional rehabilitation using fermented milk, vegetable oil and caster sugar has been tested on 54 Senegalese children, aged 6-36 months, admitted with acute diarrhoea and malnutrition. At the time of admission, 39 per cent of children were dehydrated and 26 per cent had sugar intolerance. In the course of treatment three went home against medical advice and one died from acute pneumonia with respiratory-heart failure. Among the cases of marasmus there were no differences in mean weight gain between children with sugar intolerance and others despite a longer duration of diarrhoea in the first group. Furthermore, the experimental protocol has never been compromised because of worsening diarrhoea or weight loss. These results indicate that a formula based on fermented milk together with oral rehydration can be used to treat malnourished children with acute diarrhoea and sugar intolerance.

Although few episodes of diarrhea last longer than 14 days these episodes are particularly associated with growth faltering and malnutrition. We have examined the role of the duodenal microflora in prolonging diarrhea in Peruvian children ages 3 to 36 months by comparing the microflora in 89 children with persistent diarrhea, 38 children with acute diarrhea and 34 diarrhea-free controls from the same environment. Bacteria were retrieved from 93% of all aspirates, including 94% of those from controls. There were no significant differences among the 3 groups with respect to total bacterial count, to the proportion of children with duodenal Enterobacteriaceae and to the proportion with anaerobes, lending no support to the hypothesis that proliferation of bacteria in the small intestine during the acute illness prolongs diarrhea. When only children older than 18 months were compared, anaerobes were cultured more frequently from those with persistent diarrhea than from controls, but the presence of anaerobes was not associated with adverse clinical outcome. Although malabsorption, especially steatorrhea, was common, there was no association between elevated bacterial counts and fecal loss of nutrients in 69 children who received the same diet. In this population steatorrhea could not be attributed to bacterial overgrowth.

To determine the effect of nutritional state on persistent diarrhoea a case-control study was carried out on 756 children followed up prospectively for 18 months. Children who developed persistent diarrhoea were compared with population controls and controls with acute diarrhoea. The mean weight for age in the children with persistent diarrhoea (69.9%) was significantly lower than that in the population controls (77.0%) and the diarrhoeal controls (76.2%). Weight for age of less than or equal to 70% was associated with persistent diarrhoea in both case-control analyses (population controls, matched odds ratio 3.25; diarrhoeal controls, matched odds ratio 2.46). The corrected odds (multiple logistic regression) in the two analyses were 3.2 (95% confidence interval 1.3 to 8.1) and 3.4 (1.2 to 9.1). Weight for age of less than or equal to 70% increases the risk of persistent diarrhoea. In an underweight child there is a higher risk of diarrhoea becoming persistent. Prevention of malnutrition and intensive management of acute diarrhoea in malnourished children should help reduce the risk of the diarrhoea persisting.

A protocol of nutritional rehabilitation using fermented milk, vegetable oil, and castor sugar has been tested on 54 Senegalese children age 6-36 months admitted with acute diarrhoea and malnutrition. At time of admission, 39 per cent of children were dehydrated and 26 per cent had sugar intolerance. In the course of treatment three absconded and one died from acute pneumonia with respiratory and heart failure. Among those with marasmus there were no differences in mean weight gains between children with sugar intolerance and others, despite a longer duration of diarrhoea in the first group. Furthermore, the treatment protocol has never been compromised because of worsening diarrhoea or weight loss. These results indicate that a formula based on fermented milk together with oral rehydration can be used to treat malnourished children with acute diarrhoea and sugar intolerance.

A total of 838 children under 5 yr of age were followed up in 2 villages of Punjab for a period of one year for diarrhoea morbidity, oral rehydration solution (ORS) usage and nutritional status. Overall frequency of diarrhoea was 0.78 episode/child/year. Children weighing less than or equal to 70 per cent of reference weight for age had about 25 per cent higher incidence of diarrhoea (102 episodes/100 child/yr) as compared to those who weighed greater than or equal to 71 per cent (75 episodes/100 children/yr; P less than 0.05). At the end of one year there was no significant difference in the weight and arm circumference growth of children who had diarrhoea and received ORS and those who did not. Prevalence of malnutrition (weight for age criteria) in children with and without diarrhoea at the beginning and end of the study also remained unchanged, irrespective of ORS usage. These observations indicate that in rural areas with low diarrhoea morbidity (i) pre-existing malnutrition (weight for age less than 70%) is associated with 25 per cent higher diarrhoea incidence; (ii) acute diarrhoea does not significantly affect weight and arm circumference growth and prevalence of malnutrition; and (iii) the long-term nutritional benefit of ORS if any, is doubtful.

Intestinal permeability was assessed with different-sized polyethylene glycols (PEG 400 and PEG 1,000) in small children with acute diarrhea. All children with acute diarrhea absorbed and excreted less PEG of all molecular sizes into the urine when compared with healthy control children (p less than 0.001). Children with acute rotavirus infection excreted significantly less PEG of all sizes than children with Shigella, Salmonella, and enteropathogenic Escherichia coli (EPEC) infection (p less than 0.001-0.01), suggesting a more severe mucosal lesion caused by rotavirus. In patients with severe malnutrition there was also a significant decrease in absorption of PEGs observed. In addition, malnourished patients with rotavirus diarrhea showed a pronounced decrease of PEGs in comparison with well-nourished patients. The ratio between the recovery of a large PEG molecule, 1,074 Da, and a small molecule, 370 Da, was utilized to assess the absorption of large molecules in relation to that of smaller ones. On applying this ratio, it was noted that the intestine in children with Shigella and EPEC infection was relatively more permeable to larger molecules than in healthy controls, while in rotavirus and Salmonella infection it was less permeable to larger molecules. In this study significant differences in the permeability characteristics were observed, suggesting etiology-specific effects on the mucosal barrier.

To determine the frequency with which acquired monosaccharide intolerance (AMI) occurs in infants less than 3 months of age, we performed a prospective descriptive study of infants admitted to the hospital for diarrhea. We searched for differences between the characteristics and causes of AMI in these infants and those of a cohort of similar-aged infants admitted with acute diarrhea (AD). Five hundred fifty-five infants less than 3 months of age admitted with diarrhea were enrolled. Nine percent of those infants had AMI, 40% had other forms of chronic diarrhea, and 51% had AD. The mean age at hospital admission was 32 days for the infants with AMI and 44 days for the infants with AD. The mean weight loss of AMI infants was 0.3 g/day since birth, and the mean weight gain was 14.3 g/day for AD infants. The mean dehydration by difference in weights at admission and 48 h postadmission was 5% for AMI and 3% for AD infants. Bacterial and viral causes of the diarrhea were similar. At admission to the hospital, infants in whom AMI subsequently developed were younger, more malnourished, had more prolonged diarrhea, and were more dehydrated than the AD infants. Malnutrition stands out as a significant antecedent factor that contributes to the development of AMI.

Acute diarrhoea is still a leading cause of child mortality and morbidity, second only to pneumonia as a killer of children, in India and Indonesia. Untreated diarrhoea precipitates malnutrition and is often the underlying cause of marasmus and kwashiorkor. Shigella and salmonella dysenteries are responsible for about 60% of all cases in Indonesia and India. These bacillary agents respond well to trimethoprim. Amoebiasis responds well to metronidazole. Most cases can be managed in the home, even if the exact cause is unknown, by giving liquids or a simple rehydration drink. Diarrhoea can be prevented by improving communal sanitation and personal hygiene, and by giving breast as opposed to bottle feeding of infants. Earlier introduction of supplementary feeding could provide the child with higher energy reserves giving it a better chance of survival when diarrhoeal insults occur.

Thirty-five infants of low socioeconomic status who were living in urban Santiago were hospitalized for acute diarrhea were prospectively evaluated for the presence of enteropathogens associated with the episode. Some degree of malnutrition was evident in 20 infants (57.1%); 15 of these (75%) were under 6 months of age. Mean duration of the hospital stay was 11.8 days for well-nourished patients and 15.7 days for the malnourished patients. One or more enteropathogens were found in 60% of the cases studied: in 17 cases (48.6%) these were bacteria and in four cases (11.4%) it was rotavirus. Parasites were not detected. In three patients, two different pathogens were demonstrated. Among the bacteria, 12 isolates (34.3%) were enteropathogenic E. coli (EPEC) and two (5.7%) were Shigella. Campylobacter jejuni was also isolated from two different cases (5.7%) and Salmonella from one case (2.9%). The recovery of pathogens was independent of the nutritional status. Mean age of detection of EPEC was 3.2 months among well-nourished infants and 6.2 months among the malnourished (p less than 0.001). Half of the EPEC strains isolated were multiresistant to antibiotics. One of these strains transferred some of its resistance in vitro to E. coli K12. Ampicillin and kanamycin were the antibiotics to which EPEC showed the greatest resistance. The other bacterial pathogens were mostly sensitive to antibiotics. Campylobacter jejuni, together with Shigella, was the second most frequent pathogen isolated during episodes of diarrhea. Campylobacter should be included in the routine study of diarrheal episodes in our setting.
