Oral rehydration therapy (ORT) prevents severe morbidity and death from mild to moderate dehydration from acute diarrhea for all ages and all etiologies. WHO advises ORT fluid to contain 3.5 g sodium chloride, 3.5 g potassium chloride, 2.5 g sodium bicarbonate or 2.9 g trisodium citrate dihydrate, and 20 g glucose all dissolved in 1 1 of water. This fluid does not reduce stool volume or frequency and does not curtail duration thus it is not always acceptable. Improved ORT is needed, however. The glucose concentration cannot be increased above the present 2% since an increased concentration would intensify diarrhea and dehydration. Researchers are working on an improved solution (Super ORS) which would rehydrate the body and actively bring on reabsorption of endogenous secretions in the intestine. Thus this improved ORS would reduce stool volume, shorten duration of diarrhea, and allow early introduction of feeding. Even though some studies demonstrate that fortified ORS with the amino acid glycine decreases stool volume by 49-70% and duration of diarrhea 28-30%, other studies indicate that it induces excess sodium concentrations in the blood. 1 study demonstrates that in comparison with the standard ORS, ORS fortified with the amino acid L-alanine reduced the severity of symptoms and the need for fluid in patients afflicted with cholera and enterotoxigenic Escherichia coli. Further studies reveal that rice powder based ORS (50-80 g/l) reduces stool volume 24-49% and duration of duration 30%. The advantage of using rice is that when it hydrolyzes glucose, amino acids, and oligopeptides emerge. Each 1 of these chemicals facilitate sodium absorption through separate pathways. Disadvantages include the fuel must be used to cook the rice, rice based ORS ferments within 8-24 hours making it useless, and the rice or pop rice needs to be ground.

To compare the use of rice-based oral rehydration solution (R-ORS), with the introduction of food immediately after rehydration ("early feeding"), using standard glucose-based oral rehydration solution (G-ORS) in the management of acute diarrhea, we conducted a four-cell randomized, controlled trial among 200 hospitalized Egyptian infants between 3 and 18 months of age. During the rehydration phase (first 4 hours), three groups were given G-ORS and a fourth group was given R-ORS. During the subsequent maintenance phase, the control group was given a soy-based, lactose-free formula (G-ORS + SF), a second group (G-ORS + RF) was given a rice-based formula, and a third group (G-ORS + rice) was given boiled rice. The fourth group (R-ORS + SF) continued to receive R-ORS for the first 24 hours of the maintenance period, followed by a soy-based lactose-free formula. During the first and second 24 hours of the maintenance period, infants in the three treatment groups had a lower mean stool output in comparison with the control group (p = 0.006 and 0.03, respectively). The mean total stool output in the R-ORS + SF group was significantly lower than in the control group (p = 0.02). There were no statistically significant differences among the four groups in the mean duration of diarrhea. We conclude that (1) infants who were given R-ORS had reduced total stool output (by 35%) compared with the control group and (2) feeding of boiled rice or a rice-based formula immediately after rehydration therapy was as efficacious as treatment with R-ORS alone for 24 hours, followed by feeding with a soy-based, lactose-free formula.

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.

Humans have often used oral fluids to replace perceived losses of water, either instinctively or with a therapeutic orientation in the form of folk remedies. Replacement therapy with intravenous (IV) fluids was formally introduced in the last century for the treatment of patients with cholera. The modern implementation of oral replacement therapy was begun by pediatricians in the 1940s who used electrolyte solutions as maintenance therapy in mildly purging children with diarrhea. However, the scientific development of oral rehydration therapy (ORT) has occurred only in the last 30 years. Basic physiologic research in the 1950s demonstrated the cotransport mechanism of sodium and organic solutes (sugars and amino acids) in the intestinal cells, thereby establishing the scientific basis for ORT. The use of ORT based on scientific observations was first reported in 1964 from the Philippines by Phillips and coworkers. Research laboratories in Dhaka and Calcutta subsequently demonstrated that the mechanism of sodium and glucose cotransport remains intact in cholera patients and that oral solutions can successfully rehydrate and maintain hydration in these patients. Clinical studies carried out in Dhaka and Calcutta confirmed the efficacy of oral rehydration solutions (ORS) and showed that nearly 80% of IV fluid could be saved if patients were hydrated by the oral route. Further studies demonstrated the safety and efficacy of ORT in patients of all ages suffering from acute diarrhea of any cause. The use of ORT has substantially reduced morbidity and mortality from acute diarrhea, particularly after the World Health Organization adopted and promoted ORT on a worldwide scale. Researchers continue to search for better ORS formulations in terms of safety, efficacy, availability, and cost. Food-based ORS are a promising area of research. The use of a sound scientific method, the establishment of a close link between basic and clinical science, and the use of field studies have proved to be major assets in the development of ORT.

Although the importance of oral rehydration therapy for acute diarrhea is unquestioned, controversy remains about the preparation and formulation of the oral rehydration solutions (ORS). There is disagreement about whether the ORS should be homemade or commercially prepared, what constitutes the optimal sodium content, what base (if any) should be present in the ORS, and whether other nutrients can be substituted entirely or in part for glucose. These issues are discussed and recommendations for the ideal ORS are presented.

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.

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.

Oral rehydration therapy has gained worldwide acceptance as the standard treatment for acute diarrhoeal diseases in infants and children. Besides the high sodium glucose-electrolyte solution based on the WHO/UNICEF recommendations, many diverse formulations of oral rehydration solutions (ORS) have withstood the trial of prolonged clinical use, their main differences concerning the concentration of sodium, the choice of the glycidic component, the use of bicarbonate as buffer or its substitution with acetate or citrate. It was recently hypothesized that glucose polymers-containing ORS markedly improve the intestinal sodium/glucose cotransport by delivering glucose at its critical site on the luminal villous membrane and therefore diminish stool output and duration of the diarrhoea. To investigate this hypothesis, the efficacies of two marketed ORS (table I), one containing sucrose and maltodextrin (solution A) and the other containing glucose (solution B) were compared. The study group comprised 13 infants and toddlers, 1 to 18 months old, who presented with acute diarrhea; 5 were males and 8 females; 7 were randomly allocated to receive solution A (Group A), 6 solution B (Group B). There were no significant differences between the groups in age, sex, causation of diarrhea or severity of dehydration before receiving ORS. Both groups showed a satisfactory response to 24 hours of treatment with either ORS, but a significantly lower stool output (number and global weight of stools) and higher blood glucose and bicarbonate levels were detected in group A (table II).(ABSTRACT TRUNCATED AT 250 WORDS)

An open-label inpatient study is in progress to compare the efficacy and safety of two oral rehydration solutions in children and infants with acute diarrhea and mild to moderate dehydration. One solution (ORS-60) contains 60 mmol/L of sodium and 1.8% glucose, with a total osmolality of 240 mosm/kg; the other (ORS-26) contains 26 mmol/L of sodium, 2.7% glucose, and 3.6% sucrose, with a total osmolality of 340 mosm/kg. An outcome analysis of 28 children with gastroenteritis indicated that ORS-60 (n = 13) reduced stool volume during the first eight hours after admission to a significantly greater (P less than 0.05) extent than did ORS-26 (n = 15). Diarrhea had ceased by 24 hours in 64% of ORS-60 patients but in only 31% of ORS-26 patients, and the patients' clinical condition was improved at eight hours in 84% of ORS-60 patients versus 60% of ORS-26 patients. Differences between treatments in degree of dehydration at each follow-up point, total duration of diarrhea, and duration of hospital stay were not detected. No adverse drug reactions occurred. Four patients received intravenous rehydration therapy, but none was considered a treatment failure. We conclude that the lower osmolar solution, ORS-60, conferred earlier recovery and reduced continuing fluid losses in the management of gastroenteritis.

A clinical trial was conducted to compare the safety and efficacy of a new oral rehydration solution (ORS) with that of the ORS recommended by the World Health Organization (WHO). One hundred thirty infants with dehydration due to acute diarrhea were randomized into two groups: 68 infants received the WHO ORS containing sodium and glucose in a concentration of 90 and 111 mmol/L, respectively, and an osmolality of 311 mosm/kg (ORS-90); 62 infants received an ORS containing sodium and glucose in a concentration of 60 and 90 mmol/L, respectively, with an osmolality of 240 mosm/kg (ORS-60). Treatment failure was noted in seven infants (10.3%) in the ORS-90 group; the causes of failure were high stool output (three cases), persistent vomiting (three cases), and ileus (one case). Only one patient in the ORS-60 group (1.6%) was considered a failure because of high stool output. No significant differences were noted in the serum sodium levels in either group of patients, both in relation to the natremia seen on admittance or that seen after rehydration. A trend was observed toward correction of hypernatremia or hyponatremia with both types of ORS. A similar situation was observed with respect to the variations seen in serum potassium levels. The results from this study suggest that there may be clinical advantages of using an ORS with concentrations of sodium and glucose and a total osmolality lower than that of ORS-90, because of the lower incidence of treatment failures.
