Hematological parametersand the level of highly sensitive C-reactive protein (hsCRP) were determined, and the content of products of oxida-tive modification of lipids and proteins was evaluated.</p><p><strong>Results: </strong>Activation of the processes of oxidative modification of lipids and proteins was observed in most patientswith NAFLD. According to the level of hsCRP, the presence of subclinical inflammation and the risk of developingcomplicated cardiovascular pathology was found in 58 % of patients with NAFLD. The neutrophil / lymphocyte ratiocorrelates positively with hsCRP and can be used as an available routine clinical marker for selection among patientswith NAFLD persons with increased risk of cardiovascular complications.</p><p><strong>Conclusions: </strong>HsCRP, oxidative modification products of lipids and proteins, ESR, and leukograms should be used toassess the degree of systemic inflammation in people affected by the Chornobyl accident, suffering NAFLD with con-comitant cardiovascular disease.</p>","PeriodicalId":20491,"journal":{"name":"Problemy radiatsiinoi medytsyny ta radiobiolohii","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"39773149","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
