Association Between the Degree of Nonalcoholic Fatty Liver Disease and Nocturnal Hypertension
(Lippincott Williams & Wilkins, 2025) Astan, Ramazan; Kacmaz, Fehmi; Saricam, Ersin; Ozyer, Esref Umut; Ilkay, Erdogan
Nighttime blood pressure (BP) decreases have prognostic significance owing to circadian patterns. The prevalence of nonalcoholic fatty liver disease (NAFLD) has rapidly increased in recent years. We aimed to investigate circadian blood pressure changes in patients with NAFLD. The present study included 114 patients diagnosed with nonalcoholic fatty liver disease and no previous hypertension diagnosis. Thirty patients comprised the control group (no hepatosteatosis and no hypertension). The patients were divided into 3 groups based on nocturnal BP dipping. Blood pressure patterns using night-day ratios were classified as dipper (ratio <= 0, 9), nondipper (0, 9 < ratio <= 1, 0), or nocturnal hypertension (ratio > 1, 0). There were no significant differences in sex, age, presence of diabetes, or biochemical test results between the groups. According to the blood pressure pattern, the nondipper rate in the hepatosteatosis group was significantly higher than that in the control group. Patients were compared in terms of the presence and severity of hepatosteatosis according to night blood pressure patterns. A significant difference was observed between the groups (P < .001 and P = .001, respectively). We found an association between hepatosteatosis severity and night blood pressure patterns. Patients with nonalcoholic fatty liver disease have a higher incidence of nocturnal hypertension. We observed impaired circadian blood pressure changes in patients with nonalcoholic fatty liver disease.

Background Up to 30% of patients with acute pericarditis develop recurrent pericarditis. Acute pericarditis may be a manifestation of an underlying systemic autoimmune disease. Therefore, we evaluated the characteristics of patients with acute pericarditis according to antinuclear antibodies (ANA) positivity/negativity. Methods Participants with acute pericarditis and negative ANA (n=29), recurrent pericarditis with positive ANA (n=30) and healthy controls (n=11) were examined. The groups were compared using serum parameters (ANA, C-reactive protein, leucocyte count, erythrocyte sedimentation rate, total antioxidant status, nitric oxide (NO), and oxidative stress index (OSI)) and imaging techniques (electrocardiogram, echocardiography, cardiovascular magnetic resonance, and venous Doppler ultrasound). Results In females, acute pericarditis associated with ANA occurred more frequently (p<0.001). ANA-positive acute pericarditis had significantly lower NO and OSI (p<0.05 and p<0.001, respectively) and pericardial inflammation on magnetic resonance. We found a pulmonary embolism in one patient with positive ANA. Slow venous flow (SVF) occurred more often in acute pericarditis associated with ANA than in the ANA-negative group on venous ultrasound (p<0.05). The prevalence of positive ANAs was 1.6 times higher among SVF patients than in controls. Conclusion This study suggests that acute pericarditis associated with ANA is more common in middle-aged females. SVF and lower oxidative stress tests were more common in patients with ANA-associated acute pericarditis. Acute pericarditis associated with ANA could be considered as a hypercoagulable state. Therefore, all newly diagnosed pericarditis patients (especially females) should be checked for ANA positivity. Awareness of this coexistence should be promptly addressed to establish management strategies.
