Dietary risk factors associated with acute and persistent diarrhea in children in Karachi, Pakistan.

Feeding practices may have an important impact on diarrheal diseases in developing countries. This study evaluated feeding practices in three groups of male children aged 6-36 mo: 100 with persistent diarrhea (PD), 79 with acute diarrhea (AD), and 86 in a comparison group (CG). The children came from comparably poor socioeconomic settings in Karachi, Pakistan, except that the literacy rates were higher in mothers of the CG (P = 0.0001). Although greater than 95% of all infants were breast-fed, delayed initiation of breast-feeding was more common in the diarrhea groups. Children with diarrhea were also more likely to receive supplemental milk (PD = 92%, AD = 87%) than were children in the CG (69%, P less than 0.05). Feedings were not withheld during diarrhea but changes were made in the nature of foods given. These results indicate that several feeding practices may be important risk factors for diarrhea in Pakistan.

A traditional diet as part of oral rehydration therapy in severe acute diarrhoea in young children.

Recently, the role of feeding as treatment of acute diarrhoea has received increasing attention. To assess the efficacy of early feeding in acute diarrhoea, we conducted a randomised, clinical trial of a traditional legume-based weaning diet khitchri in boys 9 to 48 months old with moderate to severe dehydration. Khitchri is composed of rice and lentils cooked with cottonseed oil. Children were randomly allocated to 2 groups: group A received only WHO ORS but no food for the first 24 hours and then khitchri and half-strength cow's milk formula freely; group B received khitchri and the half-strength formula in addition to ORS after the initial rehydration period of 4 to 6 hours. The mean period of evaluation was 3 days. 69 patients were admitted into the study, 33 in group A and 36 in group B. The initial mean purging rate for the children was greater than 200 g/kg/day. Six children did not complete the study because they developed intercurrent infections or were removed by their parents for non-medical reasons. Of the 63 patients who were evaluated, 44 (70%) were successfully treated, 21 in group A and 23 in group B. There were no significant differences in the 2 groups in mean stool output, number of stools, or weight gain, although a trend toward earlier improvement was seen in group B. These data indicate that early feeding of khitchri and WHO/ORS may be as well tolerated as WHO/ORS alone in the first 24 hours treatment of severe acute diarrhoea in young children.

Dietary management of persistent diarrhea: comparison of a traditional rice-lentil based diet with soy formula.

Recent studies have indicated that enteral diets can play an important role in the treatment of persistent diarrhea. Khitchri, a local weaning food in Pakistan, is composed of rice and lentils, which have previously been shown to be well tolerated in many children with acute diarrhea. The effectiveness of a khitchri and yogurt (KY) diet, which is inexpensive and widely available in Pakistan, was studied. One hundred two weaned boys (6 to 36 months old) with persistent diarrhea were randomly assigned to receive either soy formula (group A) or the KY diet (group B) for 14 days. Group A also received the KY diet in addition to formula for days 8 through 14. Twenty-nine children did not complete the study because of severe infection (13) or their family's decision to leave the study early (9 in group A and 7 in group B). Sixty-six children successfully completed the study protocol; there were five clinical failures in group A and two in group B. On a comparable caloric intake, there was a significantly lower stool volume (group B: 38 +/- 16 [mean +/- SD] vs group A: 64 +/- 75 g/kg per day, P less than .05) and frequency (B: 4.4 +/- 2.0 vs. A: 6.6 +/- 4.2 stools per day, P less than .005) in children fed KY during the first week of therapy. Group B children also had a significantly greater weight gain than children in group A during the first week (B: 468 +/- 373 g/wk vs A: 68 +/- 286 g/wk, P less than .005).(ABSTRACT TRUNCATED AT 250 WORDS)

Role of glucose polymer (cereal) in oral rehydration therapy.

The standard packaged glucose-based oral rehydration solution (ORS) provides optimal rehydration of acute diarrhea from any cause, but it does not reduce the volume, frequency, or duration of diarrhea. A new ORS formulation has been developed in which glucose is replaced by 50 to 60 gm of cereal flours, such as rice, wheat, maize, sorghum, or millet, or equivalent amounts of noncereal staples, such as boiled potato or plantain. In a clinical trial in children suffering from acute diarrhea, the staple-based or polymer-based ORS achieved a 40% to 60% reduction in the stool volume compared with the standard ORS. A three-cell longitudinal study in rural Bangladesh involving 2,000 children aged 1 to 4 years demonstrated the superior efficacy of rice ORS compared with glucose ORS or no ORS. The cumulative recovery rate on day 3 was 66%, 24%, and 11% in the rice ORS, glucose ORS, and comparison groups, respectively. The study suggests that staple-based or food-based ORS is the optimal treatment of diarrhea.

Food-based oral rehydration salt solution for acute childhood diarrhoea.

The efficacy in acute childhood diarrhoea of oral rehydration therapy (ORT) based on staple foods (maize, millet, wheat, sorghum, rice, or potato) was compared with that of standard ORT based on glucose. 266 children aged 1-5 years, with a history of acute diarrhoea for 48 h or less, moderate to severe dehydration, and no complications, were assigned to treatment with one of the food-based oral rehydration salt solutions (ORS) or standard ORS. The mean stool output over the first 24 h of treatment in the group receiving standard ORS was significantly higher than that of any other treatment group, and the groups receiving food-based ORT showed substantial reductions in stool output compared with the standard ORT group. Abnormalities in electrolyte concentrations were corrected in all treatment groups with similar efficiency. The digestibility of the food-based ORS was assessed by the stool pH, glucose content before and after acid hydrolysis, and osmolality; there were no significant differences between the standard ORS and food-based ORS groups. Food-based ORT should be more acceptable to users in developing countries since the mixtures are similar to traditional weaning foods and since, unlike standard ORT, it reduces stool output substantially.

Turning off the diarrhea: the role of food and ORS.

Ninety-three boys aged 5 years or less who had diarrhea due to Vibrio cholerae were randomly assigned to treatment with glucose oral rehydration salt (ORS) or rice-based ORS. For the first 24 h, ORS only was given to all the patients. During the next 24 h, ORS and normal food were given. The efficacy of the two types of ORS was compared in terms of ORS intake, stool output, change in hematocrit reading, serum specific gravity, and increase in body weight. At the end of the first 24 h of treatment, a 50% reduction in ORS intake and stool output was observed in the 47 patients randomly assigned to receive rice ORS as compared with the 46 patients who received glucose ORS. During the second 24 h of treatment, a significant reduction in the stool output was noticed in the glucose ORS group, making the efficacy of glucose ORS equal to that of rice ORS. The study suggests that normal food can impart some of the superiority of "super" ORS to standard glucose ORS with regard to reduction of stool volume.

Cereal based oral rehydration solutions.

A total of 257 boys (age range 4-55 months), who had acute diarrhoea with moderate to severe dehydration, were randomly assigned to treatment with either the World Health Organisation/United Nations Childrens Fund (WHO/Unicef) recommended oral rehydration solution or cereal based oral rehydration solution made either of maize, millet, sorghum, or rice. After the initial rehydration was achieved patients were offered traditional weaning foods. Treatment with oral rehydration solution continued until diarrhoea stopped. Accurate intake and output was maintained throughout the study period. Efficacy of the treatment was compared between the different treatment groups in terms of intake of the solution, stool output, duration of diarrhoea after admission, and weight gain after 24, 48, and 72 hours, and after resolution of diarrhoea. Results suggest that all the cereal based solutions were as effective as glucose based standard oral rehydration solution in the treatment of diarrhoea.

Gastric emptying of oral rehydration solutions in acute cholera.

Gastric emptying of rice powder electrolyte solution and of glucose electrolyte solution was measured by a marker dilution double sampling technique in 14 and in 16 adult patients respectively after intravenous rehydration during an attack of acute cholera. Six patients who received rice powder electrolyte solution and seven who received glucose electrolyte solution re-attended for a repeat study with the same test meal 16 days later, when fully recovered from cholera. No differences in gastric emptying patterns of the two electrolyte solutions were observed, either in the acute or in the recovered patients. Similarly, gastric emptying of both solutions was rapid during acute cholera and comparable to that observed in recovered patients. This study indicates that gastric emptying is not impaired in acute cholera and that the rate of emptying of oral rehydration solutions is adequate to account for their observed clinical efficacy in fast purging patients with acute cholera.

Hydrolysed wheat based oral rehydration solution for acute diarrhoea.

A randomised three cell study was carried out in 78 children with acute diarrhoea to evaluate the relative efficacy of oral rehydration solution (ORS) made from partially hydrolysed wheat grain, cooked rice powder, or glucose. Twenty six patients with comparable age, body weight, duration of diarrhoea, and degree of dehydration were studied in each of the three groups. Initial rehydration was carried out by using intravenous Dhaka solution within one to two hours followed by administration of oral rehydration solution. The mean ORS intake during the first and second 24 hours of treatment in patients with cholera receiving wheat-ORS and rice-ORS was significantly less compared with those receiving glucose-ORS. The stool output during the same period in patients receiving wheat-ORS and rice-ORS was significantly less compared with those receiving glucose-ORS. Similar trends in both ORS intake and stool output were observed during the next 24 hours.

Preserved exocrine function in patients with acute cholera and acute non-cholera diarrhoea.

Exocrine pancreatic function was assessed by means of the Lundh test in 14 patients with acute cholera and 18 patients with acute infectious non-cholera diarrhoea within the first 24 h of their admission. Mean tryptic activity amounted to 39.8 +/- 4.8 microEq/min/ml in the cholera group and to 64.4 +/- 11.0 microEq/min/ml in the non-cholera group. None of these patients shared a value below the lower limit of normal. In fact, the mean tryptic activity per 2 h was significantly higher than that reported previously in a control group from the Bengal area. It is therefore concluded that the exocrine pancreatic function is preserved and responds to food stimulation in various types of acute infectious diarrhoea, including cholera. These findings provide the pathophysiological background for the recent observation that oral rehydration solutions containing high-molecular-weight nutrients such as rice powder are at least as efficient or even more potent than the WHO-recommended glucose-electrolyte formula in acute diarrhoea.

Does oral rehydration therapy alter food consumption and absorption of nutrients in children with cholera?

In order to estimate consumption of food and absorption of nutrients, a metabolic balance study was conducted in 47 children between 1 and 5 years old, suffering from acute cholera. Twenty-two of the children were treated by intravenous solution (IV) only and 25 others by oral rehydration along with intravenous solution (ORS/IV) when necessary. After initial rehydration a nonabsorbable charcoal marker was fed to the patients followed by a typical Bangladeshi home food of known composition offered ad libitum. Appearance of the first marker in the faeces was taken as zero hour (0 h); at 72 h a second marker was fed. Faeces, urine and vomitus were collected up to the appearance of the second marker. Intake of IV fluid, ORS and any other fluid or food were recorded accurately. Samples of faeces, urine and vomitus were analysed for energy, fat and nitrogen. Consumption of nutrients and absorption in both groups were calculated. There was no significant difference in the intake or absorption of energy or carbohydrate between the two groups. The consumption of fat and protein was slightly, but significantly, lower in the ORS/IV group during the acute stage of diarrhoea than in the IV group. Absorption of nitrogen was significantly lower in the ORS/IV group, but absorption of fat was not significantly impaired. Vomiting was significantly higher in the ORS/IV group. The differences in the consumption and absorption of nutrients between the two groups were transient and came to the same level within 2 weeks after recovery.

Mothers can prepare and use rice-salt oral rehydration solution in rural Bangladesh.

A feasibility study of rice-salt solution for oral rehydration (OR) was conducted in a village in the Chandpur area of rural Bangladesh in 1983. 305 mothers of children aged 0-4 years were interviewed with a pretraining questionnaire to find out about the availability of rice. The mothers were then trained and encouraged to use rice-salt OR solution to treat patients with diarrhoea. Evaluation of training was assessed by means of field diarrhoea surveillance, case follow-up, rice-salt OR solution sample analysis, and a post-training survey. The study showed that mothers in rural areas could prepare rice-salt OR solution quite easily and use it to treat diarrhoea patients. Mothers considered that this method would increase the utilisation of OR treatment in rural homes. After training rice-salt OR solution was the most common method of treatment for diarrhoea.
