Background:
Hepatic encephalopathy (HE) is an established clinical manifestation in chronic liver disease (CLD). It is associated with various factors including gastrointestinal bleed, constipation, and dyselectrolemia. Recently 25-hydroxyvitamin D (25-OHD) deficiency has been identified as one of the factors associated with the development of HE. The current study was aimed to assess the level of 25-OHD in patients with CLD and hepatic encephalopathy and the relationship between 25-OHD deficiency and hepatic encephalopathy.
Materials And Methods:
This cross-sectional study included 100 subjects of either sex between 18 and 60 years of age, diagnosed as CLD on the basis of ultrasonography with hepatic encephalopathy and 50 age, sex-matched CLD subjects without encephalopathy. Hemogram, hepatic and renal functions, serum electrolytes, coagulation profile, and serum 25-hydroxyvitamin D levels were recorded.
Results:
The baseline variables were matched for age, sex, hepatic and kidney function, and coagulation profiles. The hemoglobin (P = 0.002) and platelet count (P = 0.0003) were significantly lower in subjects with HE. The mean level of 25-OHD was significantly lower in subjects with HE as compared to the control group (25.62 ± 21.94 nmol/L vs 37.44 ± 18.61 nmol/L, P < 0.001). The mean 25-OHD level was 30.64 ± 21.64 nmol/L in grade 1 HE, 12.03 ± 11.05 nmol/L in grade 3 with P < 0.0001, and 18.8 ± 16.88 nmol/L in grade 4 with P < 0.0001 when compared to grade 1. Moderate and severe deficiency of 25-OHD level was significantly associated with higher grades of HE, i.e. grades 3 and 4 (P < 0.0001). There was a significant negative correlation between 25-OHD levels and worsening grades of hepatic encephalopathy (person's correlation coefficient r = -0.354; P = 0.0003).
Conclusion:
In this cohort of North Indian population, serum 25-OHD level was significantly lower in patients with CLD and HE. The levels of 25-OHD showed a significant negative correlation with hepatic encephalopathy.

Serum lipids are fats and fatty substances in the blood and are crucial for various bodily functions, including energy storage, cellular structure, and hormone production. Serum lipids consist of cholesterol, triglycerides, and phospholipids.
Cholesterol is a soft, fat-like substance found in all body cells. It is crucial for producing hormones, vitamin D, and substances that aid...
