Background: Vitamin D deficiency is universal among patients with chronic liver disease. Vitamin D may be involved in the regulation of immune function of chronic hepatitis B and related to disease progression.
Methods: The study was a cross-sectional study. The level of vitamin 25(OH)D was detected in patients with chronic hepatitis B, hepatitis B cirrhosis, hepatitis B cancer, and healthy groups by isotope dilution liquid chromatography tandem mass spectrometry (LC-MS/MS). At the same time, the clinical data, biochemical indexes, and T lymphocyte subsets were collected to study the relationship between vitamin 25(OH)D deficiency and clinical indexes of hepatitis B patients.
Results: The prevalence of vitamin D deficiency (< 20 ng/mL) was higher in patients with liver cancer group (96.97%, 10.59 ± 3.06 ng/mL) and cirrhosis group (93.18%, 11.85 ± 2.66 ng/mL) than in the healthy group (76.92%, 16.38 ± 5.53 ng/mL) and chronic hepatitis B group (77.83%, 15.06 ± 4.91 ng/mL). There were significant differences in vitamin 25(OH)D levels between the cirrhosis groups and the healthy groups, the liver cancer groups and the healthy groups, the hepatitis B cirrhosis groups and the chronic hepatitis B groups, the liver cancer groups and the chronic hepatitis B groups (p < 0.05). There was no significant difference in vitamin 25 (OH)D level between liver cancer group and hepatitis B cirrhosis group, healthy group and chronic hepatitis B group (p > 0.05). Vitamin 25(OH)D level was correlated with age (r = -0.24, p = 0.015), lymphocyte (r = 0.24, p = 0.015), hemoglobin (r = 0.28, p = 0.005), platelet (r = 0.27, p = 0.006), PTA (r = 0.33, p = 0.001), albumin (r = 0.30, p = 0.002), prealbumin (r = 0.39, p = 0.001), cholinesterase (r = 0.29, p = 0.003), CD3+ (r = 0.20, p = 0.04), CD3+ CD8+ (r = 0.20, p = 0.04), CD45+ (r = 0.24, p = 0.017), but none correlated with liver function and HBV-DNA.
Conclusions: Vitamin D deficiency existed in patients with hepatitis B, which was related to the clinical progress of hepatitis B and may be involved in the regulation of immune function in patients with chronic HBV infection.
