Rheumatic heart disease in Nigerian children: clinical and preventive aspects

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.
