Delivery of Malaria Chemoprevention in the Post-discharge Management of Children With Severe Anaemia in Malawi — PMC  

Malaria Clinical Trial

Official title: Malaria Chemoprevention With Monthly Treatment With Dihydroartemisinin-Piperaquine for the Post-discharge Management of Severe Anaemia in Children Less Than 5 Years in Malawi

Status Recruiting

Clinical Trial Summary

Background and rationale: Children hospitalised with severe anaemia in Africa are at high risk of readmission or death within 6 months after discharge. No strategy specifically addresses this post-discharge period. In Malawi, 3 months of post-discharge malaria chemoprevention (PMC) with monthly 3-day treatment courses of artemether-lumefantrine (AL) in children with severe malarial anaemia prevented 31% of deaths and readmissions. The effect was in addition to the effect of insecticide-treated bednets. There is now need to design and evaluate effective delivery mechanism for PMC within the health system.

Clinical Trial Description

Objectives: The primary objective of the trial is to determine the optimum PMC delivery mechanism by comparing community- versus health facility-based strategies in order to inform policy.

Study Type: This is a single-centre, matched, cluster randomized, 5-arm, factorial design trial comparing the uptake of PMC-DHP delivered through health facility or community-based approaches with or without SMS/HSA reminders.

Site: 90 villages in the catchment areas of Zomba Central hospital in southern Malawi

Study Population:

Inclusion criteria: convalescent children aged less than 5 years and weighing >5 kg admitted with severe anaemia (haemoglobin<5g/dL / Ht<15%); clinically stable, able to take or switch to oral medication; post-transfusion Hb >5g/dL.

Exclusion criteria: blood loss due to trauma, malignancy, known bleeding disorders or sickle cell trait, known hypersensitivity to study drug, known heart conditions, non-resident in study area, previous participation in study, known need at enrolment for prohibited medication and scheduled surgery during the course of the study. HIV infection and cotrimoxazole prophylaxis are not exclusion criteria

Study Interventions:

All children will receive Dihydroartemisinin-piperaquine (3-day treatment courses, given 2,6 and 10 weeks after discharge) either:

1. at discharge + SMS Reminder;

2. at discharge + No SMS Reminder;

3. at discharge + HSA Reminder;

4. at OPD + SMS Reminder; or

5. at OPD + No SMS Reminder

Outcome Measures:

Primary: 100% of PMC drugs uptake (defined as administration of all 3-day treatment courses, given 2, 6 and 10 weeks after discharge) assessed by unannounced spot checks.

Follow-up procedures: Children will be followed up for 15 weeks by passive case detection in 2 phases: Pre-PMC (2 weeks between hospital admission and 2 weeks post-discharge); PMC (2-14 weeks post-discharge)

Sample Size: A sample size of 75 children per arm (375 total children) allows for a detection of 25% increase in uptake from 50% to 75% with 10% loss to follow-up (power 90%, α=0.05).

Data Analysis: The % of children receiving IPTpd according to schedule will be compared by relative risks (95% CI), adjusted for prognostic factors at baseline using log binomial or Poisson regression with adjustment for cluster effects ;
