[The serum neopterin level in acute rheumatic fever].

Acute rheumatic fever (ARF) is a systemic inflammatory disease etiologically related to infection with group A streptococcus characterized by a broad spectrum of disorders of cellular and humoral immunity. To estimate the activity of the immunopathological process and to forecast myocardial derangement in ARF patients, measurements were made of neopterin in the serum of ARF patients. Nine men with ARF serving in the armed forces were examined. The control group comprised 24 donors. The reference group included 13 patients with dilated cardiomyopathy and 14 with chronic myocarditis. The mean level of neopterin in ARF patients was equal to 14.5 +/- 12.2 nM/l and was significantly higher than in the donors (5.0 +/- 2.0 nM/l). In patients with dilated cardiomyopathy and chronic myocarditis, it was 9 +/- 6 and 16 +/- 11 nM/l, respectively. On more careful clinical analysis the highest level of neopterin was recorded in 3 patients with impairment of the valvular apparatus of the heart. That level was observable during the whole period of the follow-up of the patients. In other patients, no impairment of the valves was detected, whereas the concentration of neopterin fell to normal. Therefore, the rise of the level of neopterin was described for the first time in patients with ARF. Besides, a relationship was found between the high level of neopterin and impairment of the valvular apparatus of the heart.

Acute rheumatic fever.

Acute rheumatic fever (ARF) and its chronic sequela, rheumatic heart disease (RHD), have become rare in most affluent populations, but remain unchecked in developing countries and in some poor, mainly indigenous populations in wealthy countries. More than a century of research, mainly in North America and Europe, has improved our understanding of ARF and RHD. However, whether traditional views need to be updated in view of the epidemiological shift of the past 50 years is still to be established, and improved data from developing countries are needed. Doctors who work in populations with a high incidence of ARF are adapting existing diagnostic guidelines to increase their sensitivity. Group A streptococcal vaccines are still years away from being available and, even if the obstacles of serotype coverage and safety can be overcome, their cost could make them inaccessible to the populations that need them most. New approaches to primary prevention are needed given the limitations of primary prophylaxis as a population-based strategy. The most effective approach for control of ARF and RHD is secondary prophylaxis, which is best delivered as part of a coordinated control programme.
