OBJECTIVES: Behçet's disease (BD) is a unique systemic vasculitis mainly involving veins, in contrast to other vasculitides. Prior studies have shown that pulmonary arteries (PAs) have a similar structure to systemic veins. In this study we aimed to assess PA wall thickness by transthoracic echocardiography (TTE) in BD patients compared with healthy controls (HCs) and patients with non-inflammatory pulmonary embolism (NIPE).
METHODS: Patients with BD (n = 77) and NIPE (n = 33) and HCs (n = 57) were studied. PA wall thickness was measured from the mid-portion of the main PA with TTE by two cardiologists blinded to cases.
RESULTS: PA wall thickness was significantly lower in HCs [3.6 mm (s.d. 0.3)] compared with NIPE [4.4 mm (s.d. 0.5)] and BD [4.4 mm (s.d. 0.6)] (P < 0.001 for both). PA wall thickness was similar between BD and NIPE (P = 0.6). Among patients with BD, PA wall thickness was significantly higher in patients with major organ involvement compared with mucocutaneous limited disease [4.7 mm (s.d. 0.4) vs 3.7 (0.4), P < 0.001], HCs and NIPE (P < 0.001 and P = 0.006, respectively). PA wall thickness was comparable between patients with vascular and non-vascular major organ involvement [4.6 mm (s.d. 0.5) vs 4.7 (0.3), P = 0.3].
CONCLUSION: We observed that PA wall thickness was significantly higher in BD with major organ involvement compared with patients with only mucocutaneous limited disease, HCs and NIPE. These results suggest that increased PA wall thickness may be a sign of severe disease with major organ involvement in BD.
