Title: The Correlation Between Obesity-Related Diseases and Non-alcoholic Fatty Liver Disease in Women in the Pre-operative Evaluation for Bariatric Surgery Assessed by Transient Hepatic Elastography.
Abstract: BACKGROUND: Non-alcoholic fatty liver disease (NAFLD) is a common, severe disease in obese patients. However, NAFLD is usually underestimated by ultrasonography. Liver biopsy is not routinely done in bariatric surgery or during the follow-up. This study therefore examined the correlation between metabolic syndrome and NAFLD in morbidly obese patients based on an assessment using transient hepatic elastography (THE). MATERIAL AND METHODS: This study involved 50 female patients in the pre-operative phase for bariatric surgery. Before surgery, we collected clinical, laboratory, and anthropometric variables. THE measurements were obtained using a FibroScan&#174; device (Echosens, Paris, France), and steatosis was quantified using Controlled Attenuation Parameter software (CAP). Statistical analyses were done using linear correlation and the Kruskal-Wallis test. RESULTS: The mean of THE and CAP values were 7.56&#8201;&#177;&#8201;4.78&#160;kPa and 279.94&#8201;&#177;&#8201;45.69&#160;dB/m, respectively, and there was a significant linear correlation between the two measurements (r&#8201;=&#8201;0.651; p&#8201;<&#8201;0.001). The numbers of metabolic syndrome parameters did not influence the THE (p&#8201;=&#8201;0.436) or CAP (p&#8201;=&#8201;0.422) values. HbA1c and HOMA-IR showed a strong linear correlation with CAP (r&#8201;=&#8201;0.643, p&#8201;=&#8201;0.013 and r&#8201;=&#8201;0.668, p&#8201;=&#8201;0.009, respectively) and a tendency to some linear correlation with THE (r&#8201;=&#8201;0.500, p&#8201;=&#8201;0.05 and r&#8201;=&#8201;0.500, p&#8201;=&#8201;0.002, respectively). CONCLUSION: Morbidly obese women submitted to FibroScan&#174; presented a high prevalence of severe steatosis and advanced fibrosis in our sample. Insulin resistance parameters were correlated with steatosis, but less with fibrosis.
