To assess the vitamin D (VD) deficiency as a prognostic factor and effect of replenishment of VD on mortality in decompensated cirrhosis.
Patients with decompensated liver cirrhosis were screened for serum VD levels. A total of 101 VD deficient patients (< 20 ng/mL) were randomly enrolled in two groups: Treatment group (n = 51) and control group (n = 50). Treatment group received VD treatment in the form of intramuscular cholecalciferol 300000 IU as loading dose and 800 IU/d oral as maintenance dose along with 1000 mg oral calcium supplementation. The VD level, clinical parameters and survival of both the groups were compared for 6-mo.
Prevalence of vitamin D deficiency (VDD) in decompensated CLD was 84.31%. The mean (SD) age of the patients in the treatment group (M:F: 40:11) and control group (M:F: 37:13) were 46.2 (± 14.93) years and 43.28 (± 12.53) years, respectively. Baseline mean (CI) VD (ng/mL) in control group and treatment group were 9.15 (8.35-9.94) and 9.65 (8.63-10.7), respectively. Mean (CI) serum VD level (ng/mL) at 6-mo in control group and treatment group were 9.02 (6.88-11.17) and 29 (23-35), respectively. Over the period of time the VD, calcium and phosphorus level was improved in treatment group compared to control group. There was non-significant trend seen in greater survival (69% vs 64%; P > 0.05) and longer survival (155 d vs 141 d; P > 0.05) in treatment group compared to control group. VD level had no significant association with mortality (P > 0.05). In multivariate analysis, treatment with VD supplement was found significantly (P < 0.05; adjusted hazard ratio: 0.48) associated with survival of the patients over 6-mo.
VD deficiency is very common in patients of decompensated CLD. Replenishment of VD may improve survival in patients with decompensated liver cirrhosis.
Core tip: This was a prospective study to assess the vitamin D (VD) deficiency as a prognostic factor for survival in patients with decompensated chronic liver diseases (n = 101) and effect of replenishment of VD on all-cause mortality in decompensated liver cirrhosis. Treatment with VD supplement was found associated with survival of the patients over 6-mo. Replenishment of VD along with calcium supplementation may improve survival in patients with decompensated cirrhosis. These findings need to be confirmed in larger multicenter studies.
