Vitamin A, C and E levels in patients with Non-Alcoholic Fatty Liver Disease: An Indian Cohort Study

This study aimed to investigate the levels of vitamins A, C, and E in patients with Non-Alcoholic Fatty Liver Disease (NAFLD) compared to healthy controls and to explore the correlation between these vitamin levels and various other parameters, including bone mineral density (BMD), adiposity (fat storage), insulin resistance and subclinical inflammation. The study involved 50 participants diagnosed with NAFLD and 50 healthy controls. Blood samples were collected to measure vitamin A, C and E levels, along with other parameters like insulin, inflammatory markers, and liver function tests. Additionally, participants underwent DEXA scans to assess BMD and body composition. Vitamin levels: The study found no significant deficiencies in vitamin A or C levels in either group. However, vitamin E levels were significantly higher in the NAFLD group compared to controls, although only one case of vitamin E deficiency was observed in the NAFLD group. No significant correlations were found between vitamin levels and BMD, adiposity parameters, insulin resistance, or subclinical inflammation markers in either group. The study acknowledges the limited data available on the association between NAFLD, vitamin levels and BMD in the Asian Indian population. The findings regarding vitamin A and C levels are consistent with some previous studies, whereas the higher vitamin E levels in the NAFLD group contradict other research. This discrepancy might be due to factors like sample size, dietary habits, or vitamin fortification programs. The lack of significant correlations between vitamin levels and other parameters suggests that further research is needed to understand the complex interplay between these factors in NAFLD development and progression.
