Feasibility of cystatin c determination for early diagnosis of kidney damage in patients with type 2 diabetes combined with nonalcoholic fatty liver disease and obesity exposed to COVID-19 infection in the past

Abstract

The aim: To examine the diagnostic possibilities of determining the level of cystatin C in the blood serum in order to ascertain the functional status of the kidneys in patients with type 2 diabetes (those who recovered from COVID-19 infection) depending on the presence or absence of non-alcoholic fatty liver disease (further – NAFLD) and malnutrition. Materials and methods: We investigated 18 patients with type 2 DM, who were included in the first group of the patients examined; group 2 consisted of 20 patients with type 2 DM and non-alcoholic fatty liver disease (NAFLD), namely with non-alcoholic steatohepatitis; and group 3 of the patients examined consisted of 30 patients with type 2 DM and obesity.
