Effect of High Serum Ferritin on Extent of Involvement of COVID-19 Associated Mucormycosis.

Coronavirus disease 2019 attributed to severe acute respiratory syndrome has been implicated with life threatening opportunistic infections like mucormycosis. COVID-19 is a hyperferritinemic syndrome and emerging data project the role of iron in the susceptibility and pathogenesis of mucormycosis but whether high ferritin is an indicator of severity of mucormycosis is debated. The study aimed to determine the relationship between serum ferritin levels and the extent of involvement of COVID-19 associated mucormycosis. A hospital based observational study was conducted with a sample size of 70. All biopsy confirmed cases of COVID-19 associated mucormycosis were included. Retrospective data from hospital records prepared at the time of patient admission were retrieved. The imaging data was used to determine the extent of disease involvement and serum ferritin values were analysed. During the study period 40 patients had mild extent mucormycosis and 30 had severe extent. A statistically significant difference was seen in levels of serum ferritin between mild extent mucormycosis and severe extent involvement (p < 0.01). COVID-19 associated Mucormycosis patients tend to have higher serum ferritin values especially in severe extent disease and with active COVID-19 infection along with diabetes mellitus as a potent aggravating factor.
