The lack of correlation between the severity and duration of olfactory disturbances and serum levels of inflammatory markers seems to further suggest that the pathogenetic mechanisms underlying the loss of smell in coronavirus disease 2019 patients are related to local rather than systemic inflammatory factors.<\/jats:p><\/jats:sec>","DOI":"10.1017\/s0022215121001651","type":"journal-article","created":{"date-parts":[[2021,6,29]],"date-time":"2021-06-29T10:33:11Z","timestamp":1624962791000},"page":"723-728","source":"Crossref","is-referenced-by-count":24,"title":["Systemic
