RESUMO

Nonalcoholic fatty liver disease (NAFLD) has currently emerged as the most common liver disorder in both developed and developing countries. It has been observed that NAFLD exhibits sexual dimorphism, and there is limited understanding on the sex differences in adults with NAFLD. Nonalcoholic fatty liver disease shows marked differences in prevalence and severity with regards to gender. There are considerable biological disparities between males and females attributed to differences in the chromosomal makeup and sex hormone levels, distinct from the gender differences resulting from the sociocultural influences that lead to differences in lifestyle, which have a significant impact on the pathogenesis of this complex disorder. A multitude of factors contributes to the gender disparities seen and need to be researched in-depth to better understand the mechanisms behind them and the therapeutic measures that can be taken. In this article, we will review the gender disparities seen in NAFLD, as well as recent studies highlighting certain gender-specific factors contributing to its varying prevalence and severity.

RESUMO

BACKGROUND AND AIMS: Despite strong associations between non-alcoholic fatty liver disease (NAFLD) and type 2 diabetes (T2D), it is unclear which patients need oral glucose tolerance testing (OGTT). Relationships between hyperglycemia, postprandial hyperinsulinemia and NAFLD severity also need clarification. METHODS: Among 111 consecutive NAFLD patients, 35 had established T2D; 70 of the remaining 76 underwent 75G OGTT with fasting, 60 and 120 min insulin. Hepatic fibrotic severity was estimated by NAFLD fibrosis score and evidence of cirrhosis. RESULTS: Twenty-four (33%) showed abnormal glucose tolerance: seven T2D, 17 impaired glucose tolerance (IGT). NAFLD patients with newly diagnosed T2D or IGT were (mean) 9 years older and more likely female (54% vs 30%). Fasting hyperglycemia (5.6-6.9 mmol/L) had limited sensitivity (46%) but high specificity (89%) for identifying patients with IGT/T2D; positive and negative predictive values were 69% and 76%. Postprandial hyperinsulinemia (120 min) was evident in all non-diabetic NAFLD cases, and values were higher (151 ± 87 vs 82 ± 53 mU/L, P = 0.001) in those with abnormal OGTT. Patients with established diabetes were more likely to have cirrhosis (40%) than those with IGT (12%) or normal glucose tolerance (4%). CONCLUSIONS: All NAFLD patients have postprandial hyperinsulinemia, and OGTT reveals a high frequency of previously unsuspected IGT or T2D. Such testing would identify individuals who may benefit from early intervention to improve insulin sensitivity and prevent diabetes and progression to cirrhosis.

RESUMO

OBJECTIVE: Rice is the staple diet in many Asian countries. Current endoscopic guidelines advice a 6 h fast for solids and a 4 h fast for liquids before the procedure. However, these guidelines focus on a Western type diet. The aim of the study was to determine if a 6 h fast for rice is sufficient prior to upper gastrointestinal endoscopy (UGIE). PATIENTS AND METHODS: After informed consent, 212 patients referred for UGIE, who had no alarm symptoms, were randomized into two groups in preparation for UGIE. Fasting 6 h after a rice meal (R6) or fasting 10 h after a rice meal (R10). All meals contained lentils and an egg, and were isocaloric. Endoscopic vision was graded as poor, average, or good. RESULTS: In the R10 group (n = 107) vision was poor in 2 (1.9%), average in 7 (6.5%), and good in 98 (91.6%). While in the R6 group (n = 105) vision was poor in 30 (28.6%), average in 19 (18.1%), good in 56 (53.3%). The observed difference of percentages among the two groups for endoscopic vision was significant (M-H Chi-Square for trend = 25.67; df = 1; p < 0.001). CONCLUSIONS: Fasting for 6 h after a rice based meal seems inadequate for UGIE. Fasting for 10 h significantly improves endoscopic vision. Current guidelines need to be re-evaluated for populations where rice is the staple diet.
