ABSTRACT
Objective: To detect and compare serum lipid abnormalities in patients diagnosed with different grades of non-alcoholic fatty liver on ultrasonography.Methods:A total of 70 cases which included 30 males and 40 females, diagnosed as non-alcoholic fatty liver disease (NAFLD) on ultrasound were investigated with serum lipid profile. Then a comparison of lipid abnormalities between different grades of fatty liver diagnosed on ultrasound was done. P value was calculated by using analysis of variance test (ANOVA) and P value <0.05 was considered as statistically significant.Results:Out of 70 cases which were diagnosed as NAFLD cases were 47.15%, grade II were 42.85% and grade III were 10%. The mean age of the patients was 49.14 years. Male to female ratio was 3:4. Serum triglycerides, total cholesterol, LDL and VLDL levels were raised in 67.14%, 45.71% 34.28%, 25.71% of cases respectively. Low serum HDL levels were seen in 62.85% of patients. On statistical analysis we found increasing grades of NAFLD were significantly associated with increasing values of total cholesterol (P value-0.001), LDL (P value-0.000) and VLDL (P value-0.003) and decreasing HDL (P value-0.000).Conclusion:Most of the patients of NAFLD in India is asymptomatic, non-diabetic and on ultrasonography, grade I NAFLD non-hypertensive. Though liver biopsy is the gold standard method for diagnosis of NAFLD, Ultrasonography which is non-invasive, simple tool, can be used for the early detection of NAFLD in asymptomatic patients.
