This study, conducted by research institutes from Vietnam and Germany, investigated the adverse effects of vitamin D deficiency on liver diseases associated with hepatitis B infections in patients in Vietnam. Vitamin D levels were determined in 400 chronic hepatitis B patients and 122 healthy control persons. The study results showed vitamin D inadequacy in both groups. However, vitamin D deficiency and severe vitamin D deficiency were more common in hepatitis B patients. Additionally, reduced vitamin D levels were associated with a significant clinical progression of hepatitis B-related liver cirrhosis. Vitamin D deficiency was found in the majority of these patients and was associated with adverse clinical outcomes. Based on these results, it was concluded that vitamin D supplementation could benefit this group of patients. You can find more information in the study.
