Objectives. Autonomic dysfunction (AD) is frequent in sarcoidosis and considered a result of small fiber neuropathy. A non-dipper blood pressure (BP) pattern, which is also linked to AD, is associated with increased risk of cardiovascular and renal diseases. The aim of the present study was to evaluate the non-dipping BP pattern in normotensive patients with pulmonary sarcoidosis (PS). Methods. Sixty-three normotensive patients with PS (group 1) and 49 healthy subjects (group 2) were prospectively enrolled. Ambulatory BP monitoring was performed in all participants over a 24-h period. Results. The non-dipping BP pattern was significantly more frequent in patients with PS compared with the control group (80% vs 53%, respectively, p = 0.002). More advanced PS (grade 2) was an independent predictor of non-dipper BP pattern (odds ratio = 10.4, 95% confidence interval 1.1-95.4, p = 0.03). Masked hypertension and body mass index were also found to be other predictors of non-dipping BP pattern. Conclusions. The present study showed that non-dipping BP pattern is frequently observed in normotensive patients with PS. The probable mechanism underlying the non-dipping BP in PS is autonomic nervous system dysfunction. PS represents an independent risk factor for non-dipping BP and these patients have increased cardiovascular risk.
