Abstract

According to WHO, about 150-200 million people are currently infected with the HCV virus worldwide. Recently, in the professional literature, the number of publications on the role of vitamin D in patients with viral hepatitis C has increased as vitamin D metabolism occurs with the participation of the liver and its deficiency is associated with an increased risk of infectious diseases. The aim of this study was to investigate the effect of seasonal factor on vitamin D (25 hydroxycalciferol) levels in patients with chronic viral hepatitis C and healthy subjects. The study involved 100 patients in the registry of patients with chronic viral hepatitis in the Dnipropetrovsk region. The prevalence and deficiency of vitamin D in patients with chronic viral hepatitis C and conditionally healthy subjects at different times of the year were determined, which showed the presence or absence of a seasonal effect on serum 25(OH)D level. Patients were divided into two groups, depending on the time of the year (autumn-winter and spring-summer), in which the level of 25 (OH) D was determined. The serum was metabolised by vitamin D, which is synthesized by the liver – 25 hydroxycalciferol (25 (OH) D), an indicator of the supply of vitamin D to the human body. Vitamin D levels were evaluated according to the M.F. Holick classification. According to the level of vitamin D patients were divided into 3 groups (patients with normal level, insufficient (suboptimal) level and vitamin D deficiency). The results of the study showed no effect of seasonal factor on the level of 25 (OH) D in the serum of patients with chronic viral hepatitis C. Vitamin D levels are controlled by the time of the year: in spring and summer this indicator is normal, in autumn and winter – seasonal decrease in vitamin D.
