Giriş:
Bu çalışma, karotis intima-media kalınlığı (C-IMT) ve akım aracılı dilatasyon (FMD) ölçümleri ile alkol dışı yağlı karaciğer hastalığı (NAFLD) olan bireylerde endotel disfonksiyonu ve vasküler değişiklikleri değerlendirmeyi amaçlamıştır.
Yöntem:
Bu prospektif gözlemsel kohort çalışmasına, karaciğer biyopsisi ile tanısı doğrulanmış 51 NAFLD hastası ve 21 sağlıklı kontrol birey dâhil edilmiştir. Endotel fonksiyonu, brakiyal arter FMD ve C-IMT ölçümleri için yüksek çözünürlüklü ultrasonografi kullanılarak değerlendirilmiştir. Hepatotoksik ilaç kullanımı, anlamlı alkol tüketimi veya diğer karaciğer hastalıkları olan bireyler çalışma dışında bırakılmıştır. Demografik veriler, vücut kitle indeksi (VKİ) ve bel çevresi kaydedilmiştir. İstatistiksel analizler SPSS programı ile gerçekleştirilmiş olup, anlamlılık düzeyi P < 0.05 olarak kabul edilmiştir.
Bulgular:
NAFLD hastalarında, kontrol grubuna kıyasla VKİ, bel çevresi ve diyastolik kan basıncı anlamlı düzeyde yüksek bulunmuştur. Ortalama C-IMT değeri NAFLD grubunda (0.67 ± 0.09 mm), kontrol grubuna (0.52 ± 0.11 mm; P < 0.001) göre belirgin şekilde artmış; FMD ise NAFLD hastalarında (%7.3 ± 4.8), kontrollere (%16.5 ± 7.1; P < 0.001) kıyasla anlamlı olarak azalmıştır. FMD ve C-IMT değerleri, basit steatoz olgularına kıyasla NASH olgularında daha kötü bulunmuştur. FMD ile VKİ, bel çevresi ve C-IMT değerleri arasında anlamlı negatif korelasyon saptanmıştır.
Sonuç:
Özellikle NASH’li NAFLD hastalarında, azalmış FMD ve artmış C-IMT ile karakterize belirgin endotel disfonksiyonu gözlenmiştir; bu durum erken aterosklerozun göstergesi olabilir. Bulgular, NAFLD’nin ilerlemesiyle birlikte endotel disfonksiyonunun arttığını göstermektedir. NAFLD hastalarında vasküler değişikliklerin erken dönemde tanınması, kardiyovasküler riskin ve hastalık progresyonunun azaltılmasına yönelik zamanında müdahalelere olanak sağlayabilir.

Aims: This study aimed to evaluate endothelial dysfunction and vascular changes in non-alcoholic fatty liver disease (NAFLD) patients by measuring carotid intima-media thickness (C-IMT) and flow-mediated dilation (FMD).
Methods: This prospective observational cohort study included 51 biopsy-proven NAFLD patients and 21 healthy controls. Endothelial function was assessed using high-resolution ultrasonography to measure brachial artery FMD and C-IMT. Patients with hepatotoxic drug use, significant alcohol consumption, or other liver diseases were excluded. Demographic data, body-mass index (BMI), and waist circumference were recorded. Statistical analyses were conducted using SPSS, with significance set at p<0.05.
Results: NAFLD patients showed significantly higher BMI, waist circumference, and diastolic blood pressure compared to controls. The mean C-IMT was elevated in NAFLD patients (0.67±0.09 mm) compared to controls (0.52±0.11 mm; p<0.001), and FMD was significantly reduced in NAFLD patients (7.3±4.8%) compared to controls (16.5±7.1%; p<0.001). FMD and C-IMT values were lower in NASH cases than in simple steatosis. A significant negative correlation was observed between FMD and BMI, waist circumference, and C-IMT values.
Conclusion: NAFLD patients, particularly those with NASH, exhibit significant endothelial dysfunction characterized by reduced FMD and increased C-IMT, indicating early atherosclerosis. These findings suggest that endothelial dysfunction increases with progression of NAFLD. Early recognition of vascular changes in NAFLD patients could facilitate timely interventions to reduce cardiovascular risk and disease progression.
