Patient information sheet
Condition
HIV-related opportunistic infection/ cryptosporidiosis
Intervention
Nitazoxanide suspension: 200 mg twice a day (bid) for 28 days (if 1-3 years old) or 400 mg bid for 28 days (if 4-11 years old), or matching placebo.
Total duration of follow-up: 4 weeks. However, a provision was included to allow compassionate open-label treatment for children who did not respond. This could have allowed extension of the period of follow-up by 60 days, therefore, it was possible for the children to be followed up for 88 days in total.

Primary outcome measures
Proportion of children achieving 'well' clinical response and time to 'well' clinical response. Well response is defined as the patient experiencing no symptoms of C. parvum infection and passing no watery stools within the previous 48 hours.
Secondary outcome measures
1. Proportion of children achieving eradication of oocysts of C. parvum from two consecutive stool samples, and time to eradication
2. Time to well clinical response and eradication of oocysts from the stool
3. Mortality at 4 weeks
4. Rate of reduction in diarrhoea frequency based on daily evaluation over 4 weeks
5. Nutritional response (change over time in weight for age z scores, weight for height z scores, height for age z scores and mid-upper arm circumference) based on daily evaluation over 4 weeks
