Used alongside rehydration therapy, probiotics appear to be safe and have clear beneficial effects in shortening the duration and reducing stool frequency in acute infectious diarrhoea. However, more research is needed to guide the use of particular probiotic regimens in specific patient groups.
Nitazoxanide vs. probiotics for the treatment of acute rotavirus diarrhea in children: a randomized, single-blind, controlled trial in Bolivian children.
In previous studies, nitazoxanide has demonstrated a cytoprotective effect against rotavirus, reducing the duration of diarrhea in comparison to placebo. We designed a randomized, single-blind, controlled trial in order to assess the effectiveness of nitazoxanide and probiotics in comparison with a control group.
                Seventy-five children aged from 28 days to 24 months, with rotavirus diarrhea, were randomly assigned to receive either oral nitazoxanide (15 mg/kg/day) twice a day for three days, a combination of oral probiotics, 1 g twice a day for five days, or only oral or systemic rehydration solutions. The duration of diarrhea and of hospitalization were the primary outcome measures, and daily stool frequency, vomiting, and fever were some of the secondary outcome measures analyzed.
                The median duration of hospitalization was significantly shorter (p = 0.017) in patients who received nitazoxanide (81 h) and probiotics (72 h) compared to patients who received oral rehydration solution alone (108 h). Similarly, the median duration of diarrhea was significantly reduced (p = 0.009) in children who received nitazoxanide (54 h) and probiotics (48 h) compared to the control group (79 h).
                Treatment with nitazoxanide and probiotics is effective in the management of children with acute rotavirus diarrhea. Small differences in favor of nitazoxanide were found in comparison with probiotics. Nitazoxanide is an important treatment option for rotavirus diarrhea.
