Objective: Behçet's syndrome is a common disease in our country and it is thought that there may be a seasonal relationship with the exacerbation of all complications and symptoms of this disease. The aim of this study is to examine the seasonal relationship of systemic involvement in Behçet's syndrome.
Material and Methods: Seventy-seven patients older than 18 years old with systemic involvement were included in this retrospective study. Age, gender, history of Behçet's syndrome and system involvement, C-reactive protein value, erythrocyte sedimentation rate, hemoglobin, leukocyte, thrombocyte, neutrophil, lymphocyte, albumin, and creatinine values were recorded. The involvement patterns of patients with systemic involvement record due to Behçet's disease were divided into groups as arthritis, uveitis, deep vein thrombosis, uveitis+ deep vein thrombosis, neurobehçet and enterobehçet.
Results: While the mean age of the patients was 41.6±9.8 years, 31 (40%) of them were female. Pathergy test positivity was found in 38 (49%) patients. When the distribution of Behçet's syndrome system involvement was examined, 7 patients had arthritis, 36 patients had uveitis, 8 patients had deep vein thrombosis, 14 patients had uveitis and deep vein thrombosis, 10 patients had neurobehçet and 2 patients had enterobehçet. When the distribution of diagnosis dates of Behçet's syndrome involvement by seasons was examined, it was seen that patients with uveitis, deep vein thrombosis and with both involvements were diagnosed at a higher rate in spring and summer than in autumn and winter (p<0.05).
Conclusion: It was determined that the diagnosis periods of the systemic effects of Behçet's syndrome, in other words, the activation periods were related to the seasons. This relationship is thought to be due to the environmental factor effect accompanying the genetic predisposition in Behçet's syndrome etiology as in other autoimmune inflammatory diseases, and this relationship should be considered in the follow-up of patients.
