N2 - To investigate a possible association between serum vitamin D levels and spontaneous hepatitis B surface antigen (HBsAg) seroclearance. METHODS: Fifty-three patients diagnosed with chronic inactive hepatitis B and spontaneous HBsAg seroclearance were followed up in two Israeli liver units between 2007 and 2012. This retrospective study reviewed medical charts of all the patients, extracting demographic, serological and vitamin D rates in the serum, as well as medical conditions and current medical therapy. Spontaneous HBsAg seroclearance was defined as the loss of serum HBsAg indefinitely. Vitamin D levels were compared to all patients who underwent spontaneous HBsAg seroclearance. RESULTS: Out of the 53 patients who underwent hepatitis B antigen seroclearance, 44 patients (83%) had normal levels of 25-hydroxyvitamin vitamin D compared to 9 patients (17%) who had below normal levels. Multivariate analysis showed that age (> 35 years) OR = 1.7 (95%CI: 1.25-2.8, P = 0.05), serum vitamin D levels (> 20 ng/mL) OR = 2.6 (95%CI: 2.4-3.2, P = 0.02), hepatitis B e antigen negativity OR = 2.1 (95%CI: 2.2-3.1, P = 0.02), low viral load (hepatitis B virus DNA < 100 IU/mL) OR = 3 (95%CI: 2.6-4.2, P = 0.01) and duration of HBsAg seropositivity (> 8 years) OR = 1.6 (95%CI: 1.15-2.6, P = 0.04) were also associated with spontaneous HBsAg seroclearance. CONCLUSION: We found a strong correlation between normal vitamin D levels and spontaneous HBsAg seroclearance
