Abstract

Background/Aims: Vagal neuropathy, as indicated by alter-ations in standard cardiovascular tests, is frequently encountered in cirrhosis. Recently, there have been many reports about the increase in frequency of vagal neuropathy, which is a negative prognostic factor increasing mortality in hepatic cirrhosis. This study evaluated the frequency of vagal neuropathy and its relationship to age, sex, etiology, serum albumin and bilirubin levels and also prothrombin time in cirrhosis. Methods: Thirty-five patients with a definite diagnosis of hepatic cirrhosis and a control group comprising 20 healthy volunteers were included in the study. Cardiovascular reflex tests found by Ewing, Clarke, et al. were used to determine the existence of vagal neuropathy. Results: Vagal neuropathy was found to be positive in 20 (57%) patients while it was not detected in any subject in the control group. The incidence of vagal neuropathy was significantly increased in cirrhotic patients compared to the control group (p<0.001). The most abnormal test results were the heart rate responses to Valsalva maneuver and to deep breathing. Vagal neuropathy was found to have no significant relationship with etiology, sex, age and serum albumin levels but was more frequent when increased prothrombin time and high serum bilirubin levels existed (p<0.01). Conclusion: The incidence of vagal neuropathy is significantly increased in cirrhotic patients.

Özet

Amaç: Standart kardiyovasküler testlerdeki değişikliklerle gösterilen vagal nöropati, sirozda sık görülür. Vagal nöropatinin, karaciğer sirozunda mortaliteyi arttıran kötü bir prognostik faktör olduğunu bildiren yayınların artması üzerine, sirozda vagal nöropati sıklığını ve bunun yaş, cinsiyet, etyoloji, serum albumin ve bilirubin düzeyi ve protrombin zamanı ile ilişkisini araştırdık. Yöntem; Çalışmamıza kesin karaciğer sirozu tanısı almış 35 hasta ve 20 sağlıklı gönüllüden oluşan kontrol grubu alındı. Vagal nöropatinin tespiti için Ewing ve Clarke'ın bulduğu kardiyovasküler refleks testleri kullanıldı. Bulgular: Vagal nöropatinin 20 (% 57) hastada pozitif olduğu tespit edildi ve kontrol grubunda vagal nöropatiye rastlanmadı. Sirozlu hastalarda vagal nöropati sıklığı, kontrol grubuna göre çok ileri düzeyde anlamlı olarak yüksek bulunmuştur (p<0.001). En anormal test sonuçları, Valsalva manevrasına ve derin solunuma kalp hızı yanıtlarıydı. Vagal nöropatinin; etyoloji, cinsiyet, yaş ve serum albumin düzeyleriyle anlamlı bir ilişkisinin bulunmadığı; fakat sıklığının, artan protrombin zamanı ve yüksek serum bilirubin düzeylerinin varlığında arttığı tespit edildi (p<0.01). Sonuç: Karaciğer sirozlu hastalarda vagal nöropati sıklığı belirgin şekilde artmıştır.
