About this trial

The purpose of this study is to evaluate whether antibiotic treatment of non-dysentery Shigella associated watery diarrhea (NDSD) cases improves clinical outcomes and growth in children.

Children with NDSD seeking care for diarrhea at the study hospitals in Bangladesh and Zambia will be enrolled and randomized to receive Azithromycin or placebo (a look-alike substance that contains no drug). Enrolled children will be followed for three months with household visits.

The investigators will determine whether antibiotic treatment of NDSD reduces the duration of diarrhea and time to microbiological cure (shedding of Shigella in stool), and whether it improves growth in children compared with the placebo group.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Parallel

Treatments tested in this trial

  • Azithromycin

    Drug

    Azithromycin will be given as 10 mg/kg body weight once daily for 5 days

  • Placebo

    Drug

    Placebo will be similar in appearance to the intervention but will contain inactive ingredients.

Treatment groups

700 Participants
are divided into 2 treatment groups
Group A: AzithromycinExperimental treatment 1 intervention
Group B: PlaceboPlacebo comparator 1 intervention

Trial outcomes

Primary outcomes

1

Time to cessation of diarrhea (TCD)

Diarrhea will be defined as 3 or more liquid or loose stool during a 24 hours period (not calendar day). Two diarrhea episodes will be separated by three diarrhea free days in between. Time to cessation of diarrhea (TCD) will be expressed in hours.

Time frame
From the time of the administration of Azithromycin or placebo until cessation of the diarrhea episode (approximately up to a month)
2

Change in weight for age Z score (WAZ)

The change in weight for age Z scores from enrollment to the 90-day follow-up

Time frame
From enrollment to the 90-day follow up

Secondary outcomes

1

Time to microbiological cure

The interval between the administration of the intervention or placebo and two consecutive Shigella-negative stools by culture or Rapid LAMP-based Diagnostic test (RLDT) - a validated point-of-care diagnostic test.

Time frame
Enrollment to microbiological cure (up to 3 months)
2

Change in length for age Z score (LAZ)

Percentage change and mean difference in LAZ from enrollment to 90-day follow-up between the two arms.

Time frame
From enrollment to 90-day follow-up.
