Rheumatic Fever.

There have been numerous reports stating that treatment of acute rheumatic fever with either aspirin or corticosteroids does not alter the long-term outcome of rheumatic heart disease. Yet, it should be emphasized that most of these studies were carried out with the first generic corticosteroids before the advent of the more active and more potent corticosteroid agents. In spite of this caveat, there is no question that all the clinical and laboratory parameters of inflammation (erythrocyte sedimentation rate, C-reactive protein) return to normal much more rapidly with corticosteroids than with aspirin alone. It is therefore our belief that steroids should be used when clinical and laboratory evidence of carditis exists, and aspirin should be reserved for cases of acute rheumatic arthritis with no evidence of carditis. The incidence of long-term valvular disease in active carditis may be decreased with steroid therapy. For example, the number of valve replacements differs markedly in centers that do use steroids and in those that do not. In Capetown, South Africa, where steroids are routinely used for carditis, valve replacement is quite rare. In contrast, in Johannesburg, where steroids are rarely used, the rate of valve replacement is quite high. The racial backgrounds of both groups of patients are similar, thus eliminating the question of racial differences. Concerning secondary prophylaxis, there is also controversy concerning the best second-line therapy. It is now well known that monthly intramuscular injections of benzathine penicillin are really effective for only 20 days. Thus, there is a window in which penicillin coverage is not adequate. To circumvent this problem, some investigators give benzathine penicillin every 3 weeks. These injections are quite painful, however, and it has been our "rule" that compliance with this treatment is inversely proportional to the ratio of the size of the child to the mother. In our own experience over 30 years with the follow-up of more than 300 patients with acute rheumatic fever, careful discussion of the consequences of missing oral doses has been adequate to insure proper compliance. An analysis of our patients on oral penicillin prophylaxis compared with other groups using benzathine penicillin revealed that there was very little difference in recurrence rate.
