Probiotics for Children With Diarrhea

This review focuses on the efficacy of probiotics for diarrhea in children in different settings: day-care centers, diarrhea acquired in the hospital, antibiotic-associated diarrhea, and treatment of acute infectious diarrhea. For prevention of diarrhea acquired in day-care centers, 5 randomized and placebo-controlled trials have been published. Probiotics tested were Lactobacillus GG, Bifidobacterium lactis (alone or in combination with Streptococcus thermophilus), and Lactobacillus reuteri. The evidence of their efficacy in these settings is only modest: statistically significant for some strains only and in any case of minimal to mild clinical importance. Few trials have examined the potential role of probiotics in preventing the spread of diarrhea in hospitalized children, an event most commonly due to either rotavirus or Clostridium difficile, and they have yielded conflicting results. Overall, these studies provide only weak evidence on the efficacy of probiotics. On the other hand, a large number of trials on the role of probiotics in preventing the onset of antibiotic-associated diarrhea have been published. Most commonly employed probiotics were Lactobacillus GG, Bifidobacterium spp., Streptococcus spp., and the yeast Saccharomyces boulardii. In general, these trials do show clear evidence of efficacy, with the 2 most effective strains being Lactobacillus GG and S. boulardii. Today, we have a large number of published clinical trials on the role of probiotics in treating sporadic infectious diarrhea in children, and many of them are randomized, blinded, and controlled. They consistently show a statistically significant benefit and moderate clinical benefit of a few, well-identified probiotic strains-mostly Lactobacillus GG and S. boulardii, but also L. reuteri-in the treatment of acute watery diarrhea, primarily rotaviral, in infants and young children of developed countries. Such a beneficial effect seems to result in a reduction of diarrhea duration of little more than 1 day, and to be exerted mostly on diarrhea due to rotavirus. The effect is not only strain-dependent, but also dose-dependent, with doses of at least 10 billion/d being necessary.

Effect of Saccharomyces boulardii in the Treatment of Acute Watery Diarrhea in Myanmar Children: A Randomized Controlled Study

This study was conducted to evaluate the efficacy of Saccharomyces boulardii in acute diarrhea. One hundred hospitalized children in Myanmar (age range = 3 months to 10 years) were included. Fifty were treated with S. boulardii for five days in addition to oral rehydration solution (ORS) and 50 were given ORS alone (control group) in an alternating order. The mean duration of diarrhea was 3.08 days in the S. boulardii group and 4.68 days (P < 0.05) in the control group. Stools had a normal consistency on day 3 in 38 (76%) of 50 patients in the S. boulardii group compared with only 12 (24%) of 50 in the control group (P = 0.019). On day 2, 27 (54%) of 50 had less than three stools per day in the S. boulardii group compared with only 15 (30%) of 50 in the control group (P = 0.019). Saccharomyces boulardii shortens the duration of diarrhea and normalizes stool consistency and frequency. The shortening of the duration of diarrhea results in a social and economic benefits.

Use of Probiotics in Children with Acute Diarrhea

Probiotics, defined as microbial cell preparations or components of microbial cells that have a beneficial effect on the health and well being of the host, have traditionally been used to treat and prevent a variety of infections. Beneficial effects of probiotics in acute infectious diarrhea in children seem to be: (i) moderate; (ii) strain-dependent; (iii) dose dependent; (iv) significant in watery diarrhea and viral gastroenteritis, but non-existent in invasive, bacterial diarrhea; and (v) more evident when treatment with probiotics is initiated early in the course of disease. Three large, randomized controlled trials (RCTs) provide evidence of a very modest effect (statistically significant, but of questionable clinical importance) of some probiotic strains (Lactobaccillus GG, Lactobaccillus reuteri, Bifodobacterium lactis) on the prevention of community-acquired diarrhea. We have found conflicting evidence from four RCTs on the efficacy of Lactobacillus GG and B. bifidum and Streptococcus thermophilus in the prevention of nosocomial diarrhea in children. Two RCTs in children provide evidence of a moderate beneficial effect of Lactobacillus GG in the prevention of antibacterial-associated diarrhea (AAD), but results in adults are conflicting. Data on the efficacy of other probiotic strains in AAD in children are very limited. In conclusion, to date, the most extensively studied and best documented clinical application of probiotics in children is for the treatment of acute watery diarrhea of rotaviral or presumably viral etiology. Studies documenting effects in other types of diarrheal diseases in children are limited, although some preliminary results are promising. The effects of different probiotic microorganisms are not equal. Only very few probiotic strains have been tested rigorously in RCTs. Many questions remain to be answered. Future clinical trials should evaluate carefully selected, precisely defined probiotic strains and address clinically important endpoints.

Novel targets for the control of secretory diarrhoea.

Secretory diarrhoea continues to be a major clinical problem worldwide. It is now recognised that the enteric nervous system plays an important role in the pathogenesis of enterotoxin mediated intestinal secretion, which has resulted in the identification of novel therapeutic targets for the treatment of acute watery diarrhoea.

A Multinational Comparison of Racecadotril and Loperamide in the Treatment of Acute Watery Diarrhoea in Adults

Background: Racecadotril (acetorphan) is an orally active, potent inhibitor of enkephalinase, which exerts an antihypersecretory effect without increasing intestinal transit time. The aim of this study was to compare the efficacy, safety and tolerability of racecadotril with those of loperamide by assessing their effects on the resolution of the signs and symptoms of diarrhoea in patients in developing countries who had acute watery diarrhoea of less than 5 days' duration. Methods: 945 outpatients from 21 centres in 14 countries received racecadotril (100 mg) or loperamide (2 mg) three times daily in a single-blind study. Duration of diarrhoea was the primary measure of efficacy; secondary criteria were overall clinical response, occurrence and duration of abdominal pain and distension, and occurrence of other associated signs and symptoms. Occurrence of constipation and adverse events were the main safety assessments. Results: Diarrhoea resolved rapidly with both racecadotril and loperamide (55.0 h in both groups), 92% of patients on racecadotril and 93% on loperamide being treatment successes. Racecadotril produced a significantly greater reduction in abdominal pain and distension than loperamide ( P = 0.024 and 0.03, respectively). The duration of abdominal distension was significantly shorter with racecadotril (5.4 versus 24.4 h; P = 0.0001), and constipation was also significantly less frequent (16% versus 25%; P = 0.001). One-hundred-and-eighty patients (19%) experienced one or more adverse event during the study: 67 (14.2%) in the racecadotril group and 113 (23.9%) in the loperamide group ( P = 0.001). Conclusions: Racecadotril resolved the symptoms of acute diarrhoea rapidly and effectively, and produced more rapid resolution of abdominal symptoms and less constipation than loperamide.

Folic acid in the treatment of acute watery diarrhoea in children: a double‐blind, randomized, controlled trial

One‐hundred and six male children aged 6‐23 months with a history of acute watery diarrhoea of less than 72 h duration were randomized to receive either folic acid in a dose of 5 mg at 8‐h intervals or placebo for 5 d. There were 54 children in the folic acid group and 52 in the placebo group. The admission characteristics were comparable between the two groups. No significant differences were observed in the intake of oral rehydration solution or stool output between the groups. The mean ± SD of total stool output (g kg−1) was 532 ± 476 vs 479 ± 354 and the duration (h) of diarrhoea was 108 ± 68 vs 103 ± 53 in the folic acid vs placebo group, respectively. The findings, therefore, should have a positive influence on preventing the inappropriate use of folic acid in acute diarrhoea.
