Acute rheumatic fever: a single center experience with 193 clinical cases.

BACKGROUND: Acute rheumatic fever is an inflammatory disease that develops via an auto-immune mechanism following group A beta hemolytic streptococcal tonsillopharyngitis. The aim of this study was to describe the clinical presentation of and cardiac involvement in acute rheumatic fever. METHODS: The medical records of acute rheumatic fever patients admitted to the Pediatric Cardiology Unit between January 2001 and January 2013 were reviewed. The patients were divided into two groups: 53 patients admitted during January 2001-January 2007 were designated as group 1, and 140 patients admitted during January 2007-January 2013 were designated as group 2. RESULTS: A total of 193 patients were evaluated, including 53 in group 1 and 140 in group 2. There was no statistically significant difference in age, gender and latent period between the two groups. There was, however, a statistically significant difference between the annual number of cases (P=0.001). Moreover, 35 (66%) patients in group 1 and 89 (64%) patients in group 2 were admitted during the spring or winter. The most common finding, as the major criteria in the current study, was concurrent carditis and arthritis. The most common minor finding was the presence of increased acute-phase reactants. We noted a statistically significant difference between the two groups in terms of valvular involvement. Group 2 had significantly higher frequencies of isolated aortic and mitral regurgitation than group 1, but the composite frequency of these was lower. CONCLUSIONS: Acute rheumatic fever continues to be prevalent in Turkey despite the country's socioeconomic improvements. We conclude that echocardiography should be performed on all of the patients with suspected acute rheumatic fever because it markedly increases the detection of carditis.
