title: Benzathine penicillin G for rheumatic fever prophylaxis: 2-weekly versus 4-weekly regimens.
abstract: Rheumatic fever is still one of the major public health problems in Egypt and the developing countries. It is characterized by a high tendency to recur following streptococcal infections. The use of long acting penicillin for prophylaxis against strep infections was a good achievement in this field, yet, recurrences have been reported in patients following monthly prophylactic programs. Clinical experience in Alexandria have shown for a long time that giving penicillin every 2 weeks is followed by less recurrences of rheumatic fever. Recently, reports came showing that effective penicillin levels are not maintained except for 2 to 3 weeks after the injection. In the present study, we compared two regimens of prophylaxis with 190 patients in the 2-weekly regimen, and 170 patients in the 4-weekly regimen being followed up for 2 consecutive years. Two hundred and sixty nine streptococcal infections occurred during this period. Although the streptococcal infection rate was equal in both groups, the rheumatic fever recurrence rate and the RF attack rate were significantly higher in the group of patients on the 4-weekly schedule. The results of this study have shown the superiority of the 2-weekly schedule in the adequate control of RF recurrences. We suggest that this schedule should be implemented for secondary prophylaxis of rheumatic fever in Egypt and other areas with severe RF.
