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.
