A total of 186 infants, suffering from acute diarrhea were studied and divided into two groups: 84 children were placed in group A and given the ORS recommended by the World Health Organization which contains sodium and glucose at concentrations of 60 and 90 mmol/L respectively and an osmolality of 311 mOsm/kg (mmol/kg) (ORS-90). Group B included 82 children who received an ORS containing sodium and glucose at concentrations of 60 and 90 mmol/L respectively and with an osmolality of 240 mOsm/kg (mmol/kg) (ORS-60). Seven belonging to group A (8.3%) required intravenous rehydration due to the severity of the diarrhea (three cases), persistent vomiting (three cases) and paralytic ileus (one case), while only two cases belonging to group B (2.5%) required intravenous rehydration due to severe losses through feces (one case) and another due to paralytic ileus (one case). No differences were observed due to the variations in sodium concentrations among either of the groups of patients, whether that be in the natremias when admitted or once rehydrated, with a general tendency towards the correction of the hypernatremia or hyponatremia seen during admittance with both types of ORS. A similar situation was observed with the variations in serum potassium. The results obtained from this study show the different advantages of using an ORS with lesser sodium and glucose concentrations as well as minor osmolality with those from using the solution recommended by the World Health Organization, when a lesser index of failures is observed in the treatment of children with acute diarrhea with oral rehydration therapy. Yet before widely recommending its' use, it should be demonstrated that the new ORS induces lesser losses through feces during the rehydrating period in children dehydrated due to acute diarrhea.

This study was designed to assess the effect of loperamide, given to infants in higher than recommended doses, on the severity and duration of acute diarrhea. Thirty infants with acute diarrhea and dehydration were given loperamide (0.8 mg/kg/day), in addition to standard fluid therapy, for 48 hours after admission to the hospital. The stool output in grams per kilograms of body weight per day and the duration of diarrhea in these infants were compared with those in 30 matched control infants receiving only standard fluid therapy. Two infants given loperamide had to be withdrawn from the trial because ileus developed in one and the other had persistent severe vomiting. In four other infants receiving loperamide, drowsiness developed but resolved rapidly on discontinuation of the drug. Infants receiving loperamide had a shorter duration of diarrhea (median 2.5 vs 6.0 days) and lower daily stool output than the control subjects had. The study confirmed the efficacy of loperamide in reducing the duration and severity of diarrhea but raised doubts regarding its safety in the treatment of young infants.

The aetiology of acute diarrhoea was investigated in 245 children less than 3 years old in a paediatric outpatient clinic in southern India. In 55% of the children organisms were found in the stools, and one quarter were infected with multiple organisms. Viruses, enteropathogenic E. coli, shigella and campylobacter species accounted for 75% of all isolates. Cholera and helminthiasis were rare, and no child had amoebiasis. Clinical findings were useful in the diagnosis of shigella and rotavirus infection only. Children with shigellosis had classical dysentery, and a greater number of stools; they were unlikely to be breast-fed, to be less than 6 months old, or to have watery stools. Rotavirus infections were characterized by vomiting. Only 20% of the 245 children had an infection which could be treated effectively with antimicrobials.

A major cause of morbidity and mortality among children in developing countries is acute diarrhoea and rotavirus, a reovirus-like agent, is found to be a leading causative agent. We report here the incidence of rotavirus infection among infants and young children with gastro-enteritis treated at the Children's Hospital in Dammam, Kingdom of Saudi Arabia. One hundred and fifty children, aged between 1 and 60 months, suffering from diarrhoeal illness, were selected as the study cohort; another 150 hospitalized children of the same age group, but not suffering from diarrhoea, served as controls. Sixty-two per cent of the study children complained of watery diarrhoea and 39% of vomiting; all had mild to moderate dehydration. Seventy-two per cent had fever and 30% associated respiratory illness. Worst affected were those 7-12 months old, among whom rotavirus was detected by ELISA techniques in 39.6%, compared with 7.5% of the control children of comparable age group. We could not detect any rotavirus from control children aged over 36 months, whereas approximately 15% of the study children in this age group yielded rotavirus from the stool. The second most common pathogen isolated was Shigella ssp. It was isolated from 18.7% of children under study as against 3% of the controls.

Intestinal hypomotility is a common late complication in infants with acute diarrhoeal disease in pakistan. Among the infants admitted to our gastrointestinal unit with a history of acute diarrhoea, 35% developed abdominal distension and 12% developed the full clinical picture of paralytic ileus. The infants with ileus were treated with decompression and total parenteral nutrition; in this group the mortality rate was 25%. We compared 30 infants who developed ileus (group A) with an age-matched control group of infants (group B) who were admitted because of acute diarrhoea but did not develope ileus. The use of antimotility drugs was significantly more frequent in group A. Serum-K was not different in in group A (3.92 +/- 0.22 mmol/l) and group B (4.32 +/- 0.18 mmol/1). However, there were more patients who had serum-K below 3 mmol/l in group A (8/30) than in group B (5/30). We conclude that the use of antimotility drugs predisposes to the development of ileus in infants with acute diarrhoea. Hypokalemia may contribute to ileus in a few cases but is generally not a prerequisite.

We studied the absorption of both antigenic and degraded beta-lactoglobulin (beta-LG) from the ileum to the portal blood, in rabbits infected at weaning with the entero-adherent Escherichia coli strain RDEC-1. The infection was characterized by high bacterial excretion from days 7 to 18 postinfection (pi), acute diarrhea for 10 days, and considerable growth retardation. Intestinal absorption of beta-LG was measured at four stages of the infection: early (day 3 pi), peak (day 10 pi), late (day 18 pi), and recovery (day 30 pi). During the 30-day period of infection, age-matched control rabbits exhibited a significant decrease in antigenic and degraded beta-LG absorption. In both control and infected animals, more than 90% of the beta-LG was absorbed by a degrading pathway and the remainder in antigenic form by a minor pathway. RDEC-1 infection significantly raised antigenic beta-LG absorption from days 10 to 30 pi, which delayed the decrease that normally occurs with age. Degraded beta-LG absorption was not modified by the infection, except for a slight increase observed at the recovery stage (day 30 pi). These results suggest that RDEC-1 diarrhea increases absorption of food antigens. The subsequent local or systemic immune responses are not known, but pathologic consequences are possible in susceptible individuals.

In 233 patients with acute diarrhoea in paired sera Campylobacter antibodies classes IgG and IgA were assessed by the ELISA method. As antigen the external membrane protein of the strain Campylobacter jejuni was used. Raised IgG levels (greater than 50 u.) and/or IgA (greater than 80 u.) were found in 15% of all examined patients. A quadruple increase of values in one or both classes was recorded in 12.4% of the patients. The incidence of antibodies against Campylobacter jejuni provides evidence that this infectious agent is frequent in this country. Antibodies class IgA suggest by their dynamics acute contact with the Campylobacter antigen. On the other hand, IgG antibodies are not of major importance in newly diagnosed disease.

A longitudinal survey (February 1984 - January 1985) on the incidence of acute diarrhea episodes in a sample of 8,164 children (aged 0-12 years) living in southeastern Sicily was carried out by means of weekly telephone interviews with doctors practising in the territory. The incidence rate was 0.479 (0.472-0.485 95% C.I.) per child per year and the frequency of episodes was significantly higher (p less than 0.001) in children aged 0-4 years (0.86). Diarrhea was more frequent in industrial areas than in rural ones, and almost half (45.1%) of the total episodes had a mild course. No death from diarrhea occurred and admission to hospital was reported for 8.4% of all cases.

The etiology of acute diarrhea in children less than 42 months of age attending one pediatric hospital in Melbourne, Australia, was studied during a 7-month period encompassing the winter of 1984. Pathogens identified in 157 children treated as outpatients with mild disease were compared with those in 232 children hospitalized with severe disease. The pathogens (and frequencies among outpatients and inpatients, respectively) detected were rotaviruses (32.5 and 50.9%), enteric adenoviruses (8.9 and 7.4%), Campylobacter jejuni (7.2 and 1.3%), and Salmonella sp. (4.0 and 1.7%). Electropherotypes of rotavirus strains from outpatients and inpatients were compared. Two strains predominated during the 7 months of this study and were observed with equal frequency from outpatients and inpatients. Rotaviruses of the same electropherotype caused a wide spectrum of disease, with symptoms ranging from mild to severe, life-threatening diarrhea. The similarity of etiological agents identified from children with mild and severe forms of acute diarrhea suggests that the etiology of community enteric illness can be reasonably inferred from the etiology of inpatient disease in children in the same geographic area. During the winter epidemic period, the severity of symptoms associated with rotavirus infection in young children is likely to be determined by the inherent susceptibility of the host rather than by genetic differences in the strains of infecting rotaviruses.

To evaluate the magnitude of copper and zinc losses during acute diarrhea requiring hospitalization, we studied 14 infants, 3 to 14 months of age, and compared them with a control group of 15 infants of similar age, birth weight, and nutritional status. Metabolic balance studies were conducted in the study group during an initial 48 hours (period 1) and on days 6 and 7 after admission (period 2). The control group was studied after recovery from respiratory disease. Copper and zinc content of feces, urine, and food samples was measured by atomic absorption spectrophotometry. Mean (+/- SD) fecal losses were higher for period 1 in the diarrhea group than in control subjects: Cu 55.7 +/- 21.2 versus 28.8 +/- 6.7 micrograms/kg/body weight/day (p less than 0.01); Zn 159.4 +/- 59.9 versus 47.4 +/- 6.4 micrograms/kg/day (p less than 0.0001). For period 2, Zn losses were similar in both groups, but Cu balance remained negative only in the study group. Retention of Zn for the study group went from -21.2 +/- 46.7 in period 1 to 204.5 +/- 103.0 micrograms/kg/day in period 2 (p less than 0.0001), and fecal weight decreased from 70.5 +/- 20.6 in period 1 to 36.8 +/- 20.0 gm/kg/day in period 2. Fecal weight and fecal losses were correlated: r = 0.71 (p less than 0.01) for Cu and r = 0.81 (p less than 0.001) for Zn. Plasma mean Cu and Zn levels were low in period 1 but rose in period 2, especially for Zn. A negative correlation was found between fecal Zn losses and plasma Zn: r = 0.74 (p less than 0.001). We conclude that acute diarrhea leads to Cu and Zn depletion and that plasma levels and Cu balance remain abnormal a week after admission.
