Hepatitis B vaccine is available since 1982, but hepatitis B virus (HBV) infection is still a major public health problem worldwide because of its significant mortality and morbidity. Worldwide, almost 240 million individual are chronically infected with HBV (WHO, 2015). It is the reason for around half of the world's cases of hepatocellular carcinoma (HCC) and around 30% of all cases of liver cirrhosis, causing more than 780,000 deaths for every year (ElSeraq, 2011) and (Gish and Locarnini, 2007). In Egypt, hepatitis B surface antigen (HBsAg) prevalence is of moderate endemicity (2–8%). Furthermore, almost 2-3 million Egyptians are chronic carriers of HBV (Attia, 1998).
Recent evidence from various lines of research suggested that low levels of vitamin D are associated with high levels of hepatitis B virus (HBV) replication in chronic hepatitis B (CHB) infection. However, the relationship between vitamin D and occult hepatitis B infection (OBI) remains unclear. To investigate the pattern of 25 hydroxy vitamin D levels in patients with OBI, we compared serum level of vitamin D among 52 patients with CHB infection, 16 patients with OBI and 34 age & sex matched healthy control. Hepatitis B envelope (HBe) antigen was assayed among CHB patients. Also, we quantified HBV DNA viral load among both CHB and OBI groups by using Real time PCR. We found that serum level of vitamin D was significantly higher in patients with OBI than those with CHB infection but it was insignificantly differ from healthy control. Patients with HBe Ag negative had a significantly higher serum level of vitamin D than those with HBe Ag positive. Serum level of vitamin D was inversely correlated with HBV DNA viral load. It could be concluded that adequate levels of vitamin D may be one of the factors limiting the replication of HBV and decreasing viral load in patients with OBI

Maternal 25-hydroxyvitamin D [25(OH)D] deficiency has a negative influence on the health of the mother and the developing fetus. The aim of this study was to assess serum 25(OH)D status and its relationship to virologic and biochemical parameters in pregnant women with chronic hepatitis B virus (HBV) infection.
Serum 25(OH)D levels among 142 pregnant women with chronic HBV infection and 251 healthy pregnant women were measured using enzyme-linked immunosorbent assay.
The mean±SD values for serum 25(OH)D levels were 13.63±5.5 ng/mL in healthy pregnant women and 12.05±3.3 ng/mL in pregnant women with chronic HBV infection (p < 0.01). Serum 25(OH)D levels were associated with seasonal variation in healthy pregnant women (p = 0.01); however, similar results were not observed in pregnant women with chronic HBV infection (p = 0.10). Furthermore, multivariate analysis indicated that only ALT level was independently associated with severe vitamin D deficiency (p = 0.01). A significant positive correlation was found between serum 25(OH)D level and ALT level in pregnant women with chronic HBV infection (r = 0.32; p < 0.001).
Vitamin D levels were lower in pregnant women with chronic HBV infection compared with healthy pregnant women. Vitamin D supplementation can be routinely recommended for pregnant women in China.

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.

As an immune modulator, vitamin D is involved in various pathophysiological mechanisms in a plethora of diseases. This study aims to correlate the vitamin D deficiency status and clinical progression of liver diseases associated with hepatitis B virus (HBV) infection in patients in Vietnam and to compare it to healthy controls.
We quantified the levels of total vitamin D [25-(OH) D2 and D3] in serum samples from 400 HBV patients (chronic hepatitis B infection CHB, n = 165; HBV-associated liver cirrhosis [LC], n = 127; HBV-associated hepatocellular carcinoma [HCC], n = 108) and 122 unrelated healthy controls (HC). Univariate and multivariate analyses were performed in order to determine the association between vitamin D levels and distinct clinical parameters.
The prevalence of vitamin D inadequacy (<30 ng/mL) was high among healthy individuals (81.7 %) as well as in HBV patients (84.3 %). Vitamin D deficiency (<20 ng/ml) or severe deficiency (<10 ng/ml) was observed more frequently among HBV patients (52 %) and subgroups (CHB, 47.8 %; LC, 54.4 %; HCC, 55.3 %) compared to the control group (32.5 %) (P < 0.001). Vitamin D levels and HBV-DNA load were strongly and inversely correlated (rho = -0.57, P < 0.0001). Multivariate regression analysis also revealed an independent association of HBV-DNA loads with low vitamin D levels (P = 0.0004). In addition, reduced vitamin D levels were associated with significant clinical progression of LC (Child-Pugh C versus Child-Pugh A, P = 0.0018; Child-Pugh C versus Child-Pugh B, P = 0.016).
Vitamin D deficiency was observed in the majority of HBV-infected patients and associated with adverse clinical outcomes. Our findings suggest that substitution of vitamin D may be a supportive option in the treatment of chronic liver diseases, in particular of HBV-associated disorders.
