Effect of 25-OH-vitamin D3 on the Liver Transplant Recipients

Brief Summary:
The low vitamin D3 levels and malnutrition before liver transplantation showed an increase in the length of stay in ICU and hospital. Although several factors may influence the clinical outcomes of patients with liver transplantation, low vitamin D3 levels showed an independent risk factor. It is necessary to prospectively analyze the effect of vitamin D supplements on clinical outcomes in liver transplant recipients.

Condition or disease
Liver Transplant Disorder

Detailed Description:

Purpose: Vitamin D deficiency is common in patients of chronic liver disease and has been associated with infection and mortality. The aim of this study is to determine whether preoperative vitamin D levels affect clinical outcomes after liver transplantation.

Methods : This was a single-center retrospective study. Between June and November 2017, a total of 219 patients underwent liver transplantation. The primary outcome was the relationship between serum 25-OH-vitamin D3 level before liver transplantation and length of stay in the intensive care unit (ICU). Secondary outcomes included the duration of normalization of inflammatory marker, such as white blood cell count (WBC) & C-reactive protein (CRP) after liver transplantation, new infection rates, rejection rates, the length of hospital stay and mortality among vitamin D level.
