Carotid Intima-media Thickness in Patients with Non-alcoholic Fatty Liver Disease Attending a Tertiary Care Center: A Descriptive Cross-sectional Study.

Abstract

Non-alcoholic fatty liver disease is fatty infiltration of the liver in the absence of other causes of steatosis. It is strongly associated with central adiposity, high body mass index, insulin resistance states, hypertension, hyperlipidemia which are features of metabolic syndrome. The objective of study is to find out the carotid intima-media thickness of non alcoholic fatty liver disease patients attending a tertiary care center. This was a descriptive cross sectional study conducted at National Academy of Medical Sciences, Bir Hospital from July 2018 to June 2019 among 70 diagnosed cases of non alcoholic fatty liver disease based on ultrasound findings. Data collection was started after receiving ethical approval from Institutional Review Board of the Institute. Convenience sampling method was used. Data were entered using Microsoft Excel. The carotid intima-media thickness of both sides were measured by ultrasound. Statistical Package for Social Sciences version 20 was used for analysis. Out of 70 cases, the mean carotid intima-media thickness was 0.7140±0.1796mm on right and 0.7161±0.1828mm on left side. Among 70 cases 45 (64.3%) were Grade II non alcoholic fatty liver disease and 25 (35.7%) were Grade I. It was 0.5720±0.1275mm and 0.7929±0.1546mm in Grade I and II non alcoholic fatty liver disease cases respectively on right side whereas it was 0.5676±0.1259mm and 0.7987±0.1557mm respectively on left side. This study showed increased carotid intima-media thickness in non alcoholic fatty liver disease cases.
