Insights
Low vitamin D levels are common in chronic hepatitis B (CHB) patients and correlate with higher HBV-DNA. Antiviral therapy improved vitamin D status in these patients.
Area of Science:
- Hepatology
- Endocrinology
- Virology
Background:
- Vitamin D's role in chronic hepatitis B (CHB) is gaining attention.
- Low serum 25(OH)D3 levels are frequently observed in CHB patients compared to healthy individuals.
Purpose of the Study:
- To investigate the association between vitamin D levels and chronic hepatitis B.
- To explore the impact of antiviral therapy on vitamin D status in CHB patients.
Main Methods:
- A study involving 128 treatment-naïve CHB patients and 128 healthy controls.
- Measurement of serum 25(OH)D3 levels and correlation with HBV-DNA and HBeAg status.
- Assessment of vitamin D levels before and after long-term antiviral treatment.
Main Results:
- CHB patients exhibited significantly lower mean 25(OH)D3 levels and a lower percentage of sufficient vitamin D compared to controls.
- Serum 25(OH)D3 levels were negatively correlated with HBV-DNA levels and lower in HBeAg-positive patients.
- Antiviral therapy led to significant increases in mean 25(OH)D3 and the proportion of patients with sufficient vitamin D.
Conclusions:
- Low vitamin D serum levels are associated with CHB and negatively correlate with HBV-DNA.
- Effective antiviral therapy may improve vitamin D status in CHB patients.
- Maintaining adequate vitamin D levels could be important for managing CHB.
Abstract:
Recently, the role of vitamin D in chronic hepatitis B (CHB) has attracted a lot attention. In this study, 128 naïve CHB patients (91 with positive HBeAg, 37 with negative-HBeAg) were enrolled, and 128 volunteers without liver diseases were enrolled as controls. Compared to that of healthy controls, the mean level of 25(OH)D3 in CHB patients was significantly lower; and the percent of patients with sufficient 25(OH)D3 (≥20 ng/mL) was also significantly lower than that of healthy controls. Among those CHB patients, the level of 25(OH)D3 was negatively correlated with the serum HBV-DNA level. Additionally, the level of 25(OH)D3 was significantly lower in HBeAg-positive patients than that in HBeAg-negative patients. After the patients went through the long-term antiviral treatments, both the mean level of 25(OH)D3 and the percent of patients with sufficient 25(OH)D3 increased significantly. Additionally, patients who were HBeAg free after the treatment also had much higher 25(OH)D3 level than those with persistent positive HBeAg. All those data suggested that the low vitamin D serum level was dangerous for CHB patients, and the level of 25(OH)D3 was highly negatively correlated with HBV-DNA levels. Effective antiviral therapy might increase the level of vitamin D in CHB patients.
