Glycemic Control and Mucormycosis during COVID-19 Pandemic in India a Study of Stage and Outcome.

Introduction: Mucormycosis mostly targets immunocompromised patients or those with uncontrolled diabetes but is now an important complication after coronavirus disease 2019 (COVID-19) infection. The stage of mucormycosis at presentation greatly impacts its treatment course and prognosis. Prior research has failed to evaluate an association of patient factors, especially glycated hemoglobin (HbA1c) levels and random blood sugar (RBS) at presentation, with the stage and outcome of mucormycosis.

Objectives: To investigate the relationship between glycemic control and the stage of mucormycosis at presentation and to investigate various factors affecting mucormycosis outcome.

Materials And Methods: All patients with clinicopathologically confirmed mucormycosis presenting to Safdarjung Hospital, New Delhi, during the COVID-19 pandemic were enrolled in the study. A questionnaire consisting of demographic information, comorbidities, history, and treatment of COVID-19 and diabetes was filled out at the time of admission. Blood glucose and HbA1c levels at presentation were noted. The above-noted parameters were compared with the stage and outcome of mucormycosis. The data obtained was analyzed.

Results: A total of 75 mucormycosis patients were enrolled in the study. The mean age of the participants was 45.17 years, and 85.33% of them survived the disease course. There was no statistically significant difference between the survivors and nonsurvivors concerning mean HbA1c and RBS levels. But there was a statistically significant correlation such that the stage of mucormycosis increased with progressive worsening glycemic control markers HbA1c and RBS. The most common comorbid condition was diabetes mellitus (72%); however, only coronary artery disease in the patient was significantly correlated with mortality. A history of COVID-19 infection was reported in 67.6% of the patients, but this was not significantly associated with mortality outcomes. Patients without a history of COVID-19 reported significantly higher RBS and HbA1c levels at presentation than the COVID-19-associated mucormycosis group.

Conclusion: The study showed a positive correlation between the stage of mucormycosis and serum glycemic control markers at presentation. Clinicians must order blood sugar and HbA1c levels at presentation as cues for a better understanding of disease severity. A thorough clinical examination and history taking for patient risk factors predisposing to mucormycosis are also crucial since the presence of proptosis and coronary artery disease are significantly correlated with the mortality outcomes. The extent of poor glycemic control at presentation was not associated with mortality outcomes.
