Background & Aim:
Functional cure for chronic hepatitis B (CHB) patients can be achieved using nucleos(t)ide analogues (NAs) and pegylated interferon alpha (Peg-IFNα) combination treatment. However, the role of vitamin D in functional cure remains unclear. We aimed to investigate the association between vitamin D levels and functional cure in CHB patients.
Methods:
A retrospective study was conducted to detect changes in serum 25-hydroxyvitamin D (25(OH)D) levels in 526 CHB patients. Furthermore, an intervention study was conducted on 90 CHB patients with baseline vitamin D insufficiency, and 45 patients were randomly assigned to the control group receiving NAs/Peg-IFNα treatment, whereas the remaining patients were categorized into the vitamin D group (VD group) receiving NAs/Peg-IFNα treatment combined with vitamin D supplementation at 800 IU/day.
Results:
A retrospective study revealed a progressive elevation in serum 25(OH)D levels throughout the duration of treatment. The cured group displayed significantly higher serum 25(OH)D levels than the uncured group (P = 0.046) at the end of treatment, and the changes in serum 25(OH)D (Δ25(OH)D) levels between the two groups were found to be significantly different (P < 0.0001). In the intervention study, the VD group tended to have an increased functional cure rate (48.0 %) compared with the control group (34.3 %) in the binary logistic regression equation analysis (P = 0.09). Notably, a linear mixed-effects model in the longitudinal analysis indicated a significant impact of serum 25(OH)D levels on treatment outcomes (P = 0.017).
Conclusions:
Serum 25(OH)D and Δ25(OH)D were both positively associated with functional cure in this retrospective study, and vitamin D supplementation may be helpful for functional cure in CHB patients.
