Our study aimed to evaluate a possible association between the inflammatory status (reflected by serum chitotriosidase and neopterin) and the timely evolution and occurrence of chronic microvascular complications in patients with type 1 DM. This observational, cross-sectional study included 82 type 1 DM patients from the Centre for Diabetes, Nutrition and Metabolic Diseases, Cluj-Napoca, Romania. Our results demonstrated a link between the extent of inflammation, evaluated by the enzymatic activity of circulating chitotriosidase, and the onset of microvascular complications, especially diabetic neuropathy and retinopathy. Chitotriosidase enzymatic activity showed an ascending evolution over time. In non-smoking patients, the increase in chitotriosidase activity was correlated with the extent of microalbuminuria and the decline of glomerular filtration rate, while in smokers, only the presence of a positive correlation between chitotriosidase activity and disease progression was noticed. According to our results, the time span between the moment of diagnosis and the onset of microvascular complications was longer in non-smokers than in smokers. These results also imply that increased chitotriosidase activity may be a predictor of endothelial dysfunction in type 1 DM.<\/jats:p>","DOI":"10.3390\/diagnostics11020263","type":"journal-article","created":{"date-parts":[[2021,2,9]],"date-time":"2021-02-09T04:18:50Z","timestamp":1612844330000},"page":"263","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":14,"title":["Evaluation of Chitotriosidase and Neopterin as Biomarkers of Microvascular Complications in Patients with Type 1 Diabetes Mellitus"],"prefix":"10.3390","volume":"11","author":[{"given":"Ancu\u021ba","family":"Cuta\u0219","sequence":"first","affiliation":[{"name":"Department of Medical Informatics and Biostatistics, \u201cIuliu Ha\u021bieganu\u201d University of Medicine and Pharmacy, 400012 Cluj-Napoca, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9136-2530","authenticated-orcid":false,"given":"Cristina","family":"Drugan","sequence":"additional","affiliation":[{"name":"Department of Medical Biochemistry, \u201cIuliu Ha\u021bieganu\u201d University of Medicine and Pharmacy, 400012 Cluj-Napoca, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gabriela","family":"Roman","sequence":"additional","affiliation":[{"name":"Department of Diabetes, Nutrition and Metabolic Diseases, \u201cIuliu Ha\u021bieganu\u201d University of Medicine and Pharmacy, 400012 Cluj-Napoca, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0977-8874","authenticated-orcid":false,"given":"Adriana","family":"Rusu","sequence":"additional","affiliation":[{"name":"Department of Diabetes, Nutrition and Metabolic Diseases, \u201cIuliu Ha\u021bieganu\u201d University of Medicine and Pharmacy, 400012 Cluj-Napoca, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Cristina Sorina","family":"C\u0103tan\u0103","sequence":"additional","affiliation":[{"name":"Department of Medical Biochemistry, \u201cIuliu Ha\u021bieganu\u201d University of Medicine and Pharmacy, 400012 Cluj-Napoca, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Andrei","family":"Achima\u0219-Cadariu","sequence":"additional","affiliation":[{"name":"Department of Medical Informatics and Biostatistics, \u201cIuliu Ha\u021bieganu\u201d University of Medicine and Pharmacy, 400012 Cluj-Napoca, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0097-262X","authenticated-orcid":false,"given":"Tudor","family":"Drugan","sequence":"additional","affiliation":[{"name":"Department of Medical Informatics and Biostatistics, \u201cIuliu Ha\u021bieganu\u201d University of Medicine and Pharmacy, 400012 Cluj-Napoca, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2021,2,8]]},"reference":[{"key":"ref_1","unstructured":"(2020, April 13).
