Abstract:
Objective To investigate the levels and clinical significance of serum 25 -hydroxy vitamin D[25 (OH)D]in patients with chronic liver disease.Methods A total of 153 hospitalized patients with chronic liver disease in the First Affiliated Hospital of Jilin Univer-sity from June 2012 to September 2013 were enrolled in the study group.The levels of serum 25(OH)D were measured by liquid chromatog-raphy tandem mass spectrometry.The serum samples from 300 healthy volunteers who underwent physical examination in our hospital were used as controls.The study group was divided into three subgroups:non -cirrhosis,liver cirrhosis [Child -Pugh (CP)grades A,B,and C],and primary biliary cirrhosis.Comparison of continuous data between groups was made by t test and analysis of variance,and compari-son of categorical data was made by chi -square test.Correlation between different variables was investigated by Pearson linear regression a-nalysis.Results Of the 153 patients with chronic liver disease,the percentages of those who had vitamin D adequacy (≥30 ng/ml),in-sufficiency (20 -30 ng/ml),deficiency (10 -20 ng/ml),and severe deficiency (<10 ng/ml)were 20.3%,22.9%,35.9%,and 20.9%,respectively.The percentages of patients with vitamin D deficiency and severe deficiency were significantly higher in the cirrhosis subgroup than in the non -cirrhosis and primary biliary cirrhosis subgroups (41.7%,25.0% vs 27.5%,12.5% and 23.5%,17.6%,re-spectively;χ2 =6.261 -18.474,P =0.001 -0.012).The serum 25(OH)D levels in patients with cirrhosis were significantly lower com-pared with those in patients without cirrhosis and in controls (18.58 ±12.48 vs 23.78 ±11.81 and 25.69 ±12.39 ng/ml,P =0.029 and 0.001).CP class C cirrhotic patients had significantly lower serum levels of 25(OH)D compared with CP class A patients (P =0.009). Conclusion Serum 25(OH)D deficiency is common in patients with chronic liver disease.25(OH)D levels in cirrhotic patients,especial-ly in CP class C patients,are markedly lower than those in non -cirrhotic patients.
