Rheumatic heart disease in Nigerian children: clinical and preventive aspects
Insights
Secondary penicillin prophylaxis effectively prevents rheumatic fever recurrence in children with rheumatic heart disease. However, high default rates due to socioeconomic factors challenge treatment adherence.
Area of Science:
- Pediatrics
- Cardiology
- Infectious Diseases
Background:
- Rheumatic heart disease (RHD) is a significant cause of acquired heart disease in children.
- Early diagnosis and secondary prophylaxis are crucial for managing RHD and preventing recurrences.
Purpose of the Study:
- To assess the logistics and effectiveness of secondary penicillin prophylaxis in children with RHD.
- To identify factors contributing to treatment adherence and default rates.
Main Methods:
- Clinical study of 92 children with RHD over a 10-year surveillance period.
- Evaluation of monthly parenteral penicillin administration for secondary prophylaxis.
- Analysis of patient demographics, clinical presentation, and follow-up data.
Main Results:
- 88% of children presented with established RHD, predominantly mitral insufficiency.
- A high default rate of nearly 50% was observed in the surveillance clinic.
- Socioeconomic factors were identified as major contributors to the high default rate.
- Monthly penicillin prophylaxis proved effective in reducing rheumatic fever recurrence and maintaining health.
Conclusions:
- Secondary penicillin prophylaxis is effective in preventing rheumatic fever recurrence in children with RHD.
- Addressing socioeconomic barriers is essential to improve treatment adherence and reduce default rates.
Abstract:
Ninety-two children with rheumatic heart disease were studied clinically, and through a post-diagnosis surveillance period of varying duration over a 10-year period. The logistics and effectiveness of secondary penicillin prophylaxis, administered monthly, were assessed during the surveillance period. Eighty-one (88%) of the 92 children were seen for the first time with already established rheumatic heart disease. Mitral insufficiency was the major functional defect in these children whose mean age was 8.6 years. There was a high default rate of just under 50% among children referred to the surveillance clinic. Socio-economic inadequacies were found to be major factors in the high default rate. Regular monthly parenteral penicillin was found to be effective in reducing recurrence of rheumatic fever and maintaining good health in these children.
