Abstract
OBJECTIVE: To report the clinical characteristics of pulmonary artery involvement (PAI) in patients with Behçet's syndrome (BS) and to define the predictors of relapses. METHODS: We performed retrospective analysis of BS patients with PAI who fulfilled international study group criteria. Among 460 patients with vascular Behçet's syndrome (VBS), 66 were diagnosed with PAI. For final analyses, 61 patients with PAI were included who had at least 2 follow-up visits (72.1% male, mean age at BS diagnosis 29.34 ± 10.1 years). The patient data were recorded. Relapse was defined as the reoccurrence of vascular event in any vascular structure. Factors associated with relapse were assessed by logistic regression analysis. RESULTS: There were no differences considering demographic and clinical features of the patients with and without PAI in the VBS group, except that intracardiac thrombosis was more common in the patients with PAI (19.7% vs 0.3%). Among 61 patients, 50 (82.0%) had isolated pulmonary artery thrombosis (PAT), whereas 11 (18.0%) had pulmonary artery aneurysm with or without PAT. Twenty-four (39.3%) patients experienced vascular relapse during median follow-up of 65.9 (Q1-Q3: 20.1-109.0) months. To define the factors associated with relapses, patients with isolated PAT were analysed. On multivariable logistic regression analysis, older age at BS diagnosis and anticoagulation usage seemed to be protective (OR: 0.92, 95% CI 0.86-1.02, OR: 0.34, 95% CI 0.09-1.33, respectively). CONCLUSION: Our results indicate a higher frequency of intracardiac thrombosis in BS patients with PAI and possible efficacy of anticoagulation usage in preventing relapses. Key Points • This study shows that intracardiac and intracranial thromboses are seen more frequently in patients with PAI and the prevalence of pulmonary artery thrombosis has been increasing in the case of PAI. Furthermore, our report indicates that anticoagulation might be effective in preventing further vascular relapses.
