Background/Aims: NAFLD has today emerged as the leading cause of liver disorder. There is scanty data on risk factors associated with NAFLD emanating from India. The present study was conducted to identify the risk factors associated with NAFLD. Methods: 464 consecutive NAFLD patients and 181 control patients were subjected to detailed questionnaire regarding their lifestyle and dietary risk factors. Anthropometric measurements were obtained and biochemical assays were done. Comparison of different variables was made between NAFLD patients and controls using principal component analysis (PCA). Results: NAFLD patients had higher BMI [26.25 AE 3.80 vs 21.46 AE 3.08 kg/m 2 , P = 0.000], waist-hip ratio [0.96 AE 0.12 vs 0.90 AE 0.08, P = 0.000] and waist-height ratio [0.57 AE 0.09 vs 0.50 AE 0.06, P = 0.000] compared to controls. Fasting blood sugar [101.88 AE 31.57 vs 90.87 AE 10.74 mg/dl] and triglyceride levels [196.16 AE 102.66 vs 133.20 AE 58.37 mg/dl] were significantly higher in NAFLD group. HOMA-IR was also higher in NAFLD group [2.53 AE 2.57 vs 1.16 AE 0.58, P = 0.000]. Majority (90.2%) of NAFLD patients were sedentary. Family history of metabolic syndrome (MS) was positively correlated with NAFLD. Dietary risk factors associated with NAFLD were non-vegetarian diet [35% vs 23%, P = 0.002], fried food [35% vs 9%, P = 0.000], spicy foods [51% vs 15%, P = 0.001] and tea [55% vs 39%, P = 0.001]. Diabetes, hypertension, snoring and sleep apnoea syndrome were common factors in NAFLD. On multivariate PCA, waist/height ratio and BMI were significantly higher in the NAFLD patients. Conclusion: The risk factors associated with NAFLD are sedentary lifestyle, obesity family history of MS, consumption of meat/fish, spicy foods, fried foods and tea. Other risk factors associated with NAFLD included snoring and MS. ( J CLIN EXP HEPATOL 2015;5:295-302) N on-alcoholic fatty liver disease (NAFLD) is a distinct clinico-pathologic entity characterized histologically by a spectrum ranging from simple steatosis to steatohepatitis (NASH), cirrhosis and even hepatocellular carcinoma (HCC). 1,2 NAFLD (steatosis of the liver) is highly prevalent in Western countries. 1 With the introduction of westernized lifestyle and the increasing frequency of obesity in the Asia-Pacific region, the prevalence of NAFLD has increased over the past two decades.Studies from different regions of India have shown that NAFLD is very common in Indians. [3][4][5] Risk factors implicated in the development of NAFLD are obesity and metabolic syndrome (MS). 6,7 However, it is obvious that NAFLD is multifactorial and identifying the various risk factors associated with NAFLD in our population could help us to intervene in order to prevent its progression to more severe forms of the disease.The few studies identifying the risk factors associated with NAFLD have emanated from the West, where the profiles of NAFLD patients appear to be different. [8][9][10] The observed differences in Indian NAFLD patients include a lower frequency of MS, 9,11 lesser degree ...

ACLF patients in our population had high short-term mortality rates with majority of deaths in alcoholics. Alcohol intake and bacterial infections were mainly responsible for AD in our study.

In India, incidentally detected NAFLD (IDNAFLD) patients are predominantly middle aged males, most of whom are not lean. Most of these patients seek consultation for functional bowel disease.

Insulin resistance (IR) is a major factor in the pathogenesis of sepsis. Critically ill patients with multi-organ dysfunction syndrome (MODS), diagnosed as per modified Acute Physiology and Chronic Health Evaluation II (modified APACHE II) score criteria and admitted to the medical ward in our hospital, were assessed for IR and beta cell function by using the homeostasis model assessment A (HOMA-A) and HOMA-B models, respectively. Of 80 consecutive patients, 60 were followed up to day 7; 16 patients died and 4 did not agree to follow up. The mean value of IR in all the 80 patients studied on the day 1 of hospitalization was 6.67 +/- 10.65. The initial high values of serum insulin and IR were significantly reduced (p < 0.05) as these patients recovered from their critical illness. Of those who died, the first day mean insulin levels were high (13.80 +/- 14.72 micro/ml as well as IR 5.14 +/- 6.76 values), but they had statistically low beta cell function (46.45 +/- 433.64%) as compared to those who recovered (227.60 +/- 430.36%; p < 0.05). This suggests that, beta cell overexhaustion occurs in critically ill patients, because it was required to overcome the prevailing state of IR and has more bearing in patients having less than 4 organ failures. beta cell failure ensued from the onset in those who were more moribund and had more than four organs failing or those who died. IR and beta cell function are reliable indicators of the state of severity of critical illness, and they corroborated with mortality in patients with MODS.
