Mucormycosis in COVID-19 patients of severe type has been reported. This study was intended to evaluate ESR, CRP, LDH, CPK, D-Dimer, BS and FBS levels in COVID-19 patients with mucormycosis. Information was recorded including gender, age, hospitalization and recovery. The laboratory parameters contained ESR, CRP, LDH, CPK, D-Dimer, BS and FBS levels. There was a significant relationship between LDH and CPK level with hospitalization, and also, between CRP and gender. Finally, there was a significant difference between the age groups in terms of ESR. Our study showed that LDH and CPK, CRP and ESR should be considered as laboratory tests in the hospitalized COVID-19 patients with mucormycosis.
