Rheumatic Heart Disease, Pragmatic Randomized Controlled Trial, Oral Penicillin V, Group A Streptococcus
Brief summary
This study will look at whether children ages 5-8 who take Penicillin V by mouth twice a day are less likely to develop rheumatic heart disease (RHD) over a 3-year period compared to children who do not take the medicine.
Interventions
Twice-daily oral Pen V 250 mg

Eligibility
Inclusion criteria
* Age 5-8 years at enrollment * Residence within the participating study catchment area (Gulu District or Gulu City) * Normal study echocardiogram confirmed by the expert adjudication panel * Parent/guardian able and willing to provide written informed consent * Participant able to provide written assent (age 8 years)
Exclusion criteria
* History of prior ARF or RHD with or without cardiac involvement * Evidence of RHD on baseline echocardiography * Congenital heart disease (excluding small PFO, small ASD) or other cardiac abnormality at baseline echocardiography * Self-reported known allergy to penicillin * Medical conditions that would preclude safe participation, adherence, or follow-up * Anticipated inability to complete 36 months of study follow-up * Any known co-morbid condition requiring regular antibiotic prophylaxis
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Cumulative Incidence of Rheumatic Heart Disease | 3 years | Proportion of participants with newly diagnosed RHD based on blinded echocardiographic adjudication among children with a normal baseline echocardiogram. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Number of Participants who Develop Early RHD | 3 years | Proportion of participants who develop Stage A or Stage B rheumatic heart disease as determined by blinded echocardiographic adjudication. |
| Number of Participants who Develop Advanced RHD | 3 years | Proportion of participants who develop Stage C or Stage D rheumatic heart disease as determined by blinded echocardiographic adjudication. |
| Number of Participants who Develop Acute Rheumatic Fever | 3 years | Percentage of participants who develop acute rheumatic fever (ARF) diagnosed according to the 2015 Revised Jones Criteria among participants in each study arm. |
| Cumulative Incidence of RHD at Two Years | 2 years | Proportion of participants with newly diagnosed rheumatic heart disease based on blinded echocardiographic adjudication. |
| Cumulative Incidence of RHD at One Year | 1 year | Proportion of participants with newly diagnosed rheumatic heart disease based on blinded echocardiographic adjudication. |
| Number of Participants Achieving at least 80% Adherence to Oral Penicillin V Prophylaxis Based on Pill Count | 3 years | Proportion of participants assigned to Arm 2 who achieve ≥80% adherence to prescribed oral Penicillin V prophylaxis, as assessed by pill count. At each bimonthly school-based visit, remaining tablets will be counted and adherence calculated as the proportion of prescribed doses taken during the assessment interval. |
| Number of Participants Achieving at Least 80% Adherence to Oral Penicillin V Prophylaxis Based on DoseSmart® Bottle Opening Records | 3 years | Proportion of participants assigned to Arm 2 who achieve ≥80% adherence to prescribed oral Penicillin V prophylaxis, as assessed using DoseSmart® electronic bottle opening data downloaded at each bi-monthly visit. Adherence will be calculated as the proportion of expected dosing events recorded over the assessment interval. |
| Number of Participants Experiencing Treatment-Emergent Adverse Events | 3 years | Number and proportion of participants experiencing treatment-emergent adverse events, serious adverse events, treatment discontinuations, or other safety-related events attributable to oral Penicillin V. |
| Number of Participants Achieving at Least 80% Adherence to Oral Penicillin V Prophylaxis Based on Caregiver-Reported Dosing Diary | 3 years | Proportion of participants assigned to Arm 2 who achieve ≥80% adherence to prescribed oral Penicillin V prophylaxis, as assessed using a participant/parent paper diary in which caregivers record each administered dose. Adherence will be calculated as the proportion of prescribed doses documented as taken during the assessment interval. |
