Evolução clínica da doença de Behçet em paciente com atraso do diagnóstico e seguimento radiológico dos trombos com angiotomografia computadorizada: seguimento por 5 anos durante tratamento imunossupressor

Computed tomography pulmonary angiography (CTPA) in Behçet's disease patients: a remarkable gender gap and time to refine the treatment strategy

OBJECTIVE

The aim of the work was to delineate the computed tomography pulmonary angiography (CTPA) findings in Behçet's disease (BD) patients with and without chest manifestations.

PATIENTS AND METHODS

The study included 122 BD adults recruited from 5 Teaching University Hospitals in Egypt of those who agreed to perform a CTPA. The Arabic version of BD current activity form (BDCAF) and BD damage index (BDI) were assessed. Detailed pulmonary manifestations, examination, plain radiology chest, and CTPA findings were recorded.

RESULTS

The mean age of patients was 36.9 ± 11.3 years, male:female was 1.8:1, disease duration 9.6 ± 8.2 years, and age at onset 28.3 ± 8.6 years. Their mean BDCAF was 4.4 ± 2.2 and BDI 3.4 ± 1.8. There were chest manifestations in 51 (41.8%) and plain chest x-ray findings in 13 (10.7%) and CTPA findings in 31 (25.4%) in the form of pulmonary thromboembolism in 15 (12.3%), pulmonary aneurysms in 7 (5.7%), pneumonia in 5 (4.1%), interstitial lung disease in 4 (3.3%) and pleural effusion in 3 (2.5%). Patients with chest manifestations had significantly higher frequency of cardiac manifestations (15.7%) compared to those without (2.8%; p = 0.023); chest x-ray findings tended to be higher (17.6% vs 5.6%; p = 0.05) while CTPA findings were significantly detected (51% vs 7%; p < 0.0001). Higher frequency of CTPA findings were in females (p < 0.0001). Yet the rate of serious pulmonary embolisms, aneurysms, and thrombosis was exclusive in males.

CONCLUSION

Meticulous investigation of the chest manifestations is warranted in BD patients to undermine the actual magnitude of pulmonary impact. CTPA provides a realistic estimate of the extent of involvement even in asymptomatic cases. Key Points • Meticulous chest assessment is warranted in Behçet's disease patients to undermine the actual magnitude of pulmonary impact • CTPA provides a realistic estimate of the extent of involvement even in asymptomatic cases.
