Abstract We performed a case–control study across 25 hospitals in India for the period of January–June 2021 to evaluate reasons an COVID-19–associated mucormycosis (CAM) outbreak. investigated whether COVID-19 treatment practices (glucocorticoids, zinc, tocilizumab, and others) were associated with CAM. included 1,733 cases CAM 3,911 age-matched controls. found cumulative glucocorticoid dose (odds ratio [OR] 1.006, 95% CI 1.004–1.007) zinc supplementation (OR 2.76, 2.24–3.40), along elevated C-reactive protein 1.004, 1.002–1.006), host factors (renal transplantation [OR 7.58, 3.31–17.40], diabetes mellitus 6.72, 5.45–8.28], diabetic ketoacidosis during 4.41, 2.03–9.60]), rural residence 2.88, 2.12–3.79), significantly Mortality rate at 12 weeks was 32.2% (473/1,471). emphasize judicious use therapies optimal glycemic control prevent

Abstract Background Factors associated with pulmonary mucormycosis (PM) among subjects diabetes mellitus (DM) remain unclear. Following the coronavirus disease (COVID‐19)‐associated outbreak in India, specific environmental exposures (especially cattle dung exposure) were proposed as possible aetiology. We hypothesized that factors are PM. compared DM (cases) and without PM (controls). Methods In this case‐control study, for each case, we included five unmatched diabetic controls (hospital [ n = 2], community 3]) collected information on demography, COVID‐19 infection, glycated haemoglobin% (HbA1c), type of house (pucca vs. kutcha) where participants reside, other factors. The primary exposure tested was (CDE; using cakes fuel or handling). performed a multivariate logistic regression to explore report association an adjusted odds ratio (OR) 95% confidence intervals (CI). Results enrolled 39 cases 199 80], 119]). CDE (OR 0.68, CI [0.14‐3.31]; p 0.63) not increased DM. found male sex 4.07, [1.16‐14.31]), higher HbA1c 1.51, [1.18‐16.32]), 28.25, [7.02‐113.6]) residence at kutcha 4.84, [1.33‐17.52]) Conclusion Cattle Instead, sex, poor glycaemic control, housing mucormycosis.

Background: The COVID-19 pandemic caused by SARS-CoV-2 is a respiratory disease which created havoc worldwide, was accompanied another peculiar, otherwise rare, secondary fungal infection Mucormycosis observed at exceptionally high incidence in India during the second wave of COVID-19. article explores possible links between two infectious diseases to understand higher-than-normal occurrence patients. Coronavirus enters patients through ACE-2 and many other receptors like- NRP-1, TfR, CD-126, CD-26. Virus bind cells possessing these affect their proper functioning, disturbing homeostatic metabolism resulting conditions like hyperglycemia, Diabetic Ketoacidosis (DKA), low serum pH, iron overload, anemia, hypoxia, immunosuppression as explained article. All outcomes provide very supportive environment for attack spread fungi. major receptor humans GRP-78. Its expression upregulated coronavirus entry hyperferritinemia, acidic prevalent COVID patients, thus providing an easy species. Upregulation GRP-78 furthermore damages pancreatic β-cells intensifies showing quite synergic relationship. Inordinate rise cases might be facts large proportion diabetic emergence deadly strain coronavirus- Delta strain, higher doses steroids antibodies used treat against this overburdened health care services, sudden much need oxygen supply use industrial could explain outbreak Objective: present review discusses functional interdependence summarizes Mucormycosis. Conclusion: metabolic pathways affected result severe physiological conditions- DKA, immunosuppression, hypoxia. not only increase GRP-78, fungi but also play crucial role quality media fungus establish grow. Hence explains epidemic India.
