Obsessive-compulsive symptoms in adults with history of rheumatic fever, Sydenham's chorea and type I diabetes mellitus: preliminary results

Objective: Rheumatic fever (RF) associated with Sydenham's chorea (a neurological variant of RF), but not RF without chorea, has been acutely related to obsessive-compulsive symptomatology/disorder (OCS/OCD). This study investigated the presence of OCS in adults who had RF with or without chorea in childhood. Method: The Yale-Brown Obsessive-Compulsive Scale (Y-BOCS) was used to evaluate OCS in 38 adults with history of RF (13 with chorea; 25 without chorea) or diabetes (controls; n = 19). Results: The OCS was similar in both groups, although the intensity of symptoms was not clinically relevant. Moreover, subjects with RF with or without chorea did not score differently in the Y-BOCS. Conclusion: The similar occurrence of OCS in patients with history of RF and diabetes suggests that the development of this symptomatology, triggered by group A beta-haemolytic streptococcus infections, is restricted to the RF acute phase, occurred during infancy, and did not seem to predispose the appearance of OCS in adulthood.
