Breaking the mold: a brief review on the diagnostic and treatment approaches of mucormycosis

Abstract

<p class="abstract">Mucormycosis is a severe emerging angioinvasive fungal infection that occurs predominantly in immunocompromised individuals. The incidence of this disease seems to be increasing in recent years with the emergence of new causative agents and rise of the susceptible population. The present COVID-19 pandemic has seen an un-precented increase in the number of mucormycosis cases all over the world. It has emerged as one of the most common complication of COVID-19 leading to severe morality. Uncontrolled diabetes has been postulated to be the most common underlying disease in developing countries and hematological malignancies in case of the high-income countries. Besides diabetes, chronic renal failure and tuberculosis have also been predisposed in the Indian subcontinent. Rhino-cerebral form is mostly seen in diabetics whereas the pulmonary type is the most common presentation in patients with hematological malignancies and solid organ transplant. Diagnosis and treatment of this rapidly progressive disease is equally challenging. Microscopy and culture are the cornerstone for the diagnosis, but if assisted by imaging and molecular assays, it plays an important role in the correct and early identification of the causative agent. Successful management of mucormycosis is based on an integrated approach, including reversal or discontinuation of underlying risk factors, early administration of antifungal agents, and complete removal of infected tissue and use of various adjunctive therapies.</p>

Mucormycosis in Indian COVID-19 Patients: Insight into Its Patho-Genesis, Clinical Manifestation, and Management Strategies

“…Mucormycosis causes angioinvasive infection among immunocompromised patients, with a mortality rate of 60% [4]. Mucormycosis is the third most prevalent fungal infection in hematology patients, accounting for 8.3-13% of all fungal infections [5,6]. Mucorales fungi access the human body mostly by inhalation, percutaneous contact, or ingestion [7].…”

Evaluation of Direct Examination, Culture, and Histopathology in the Diagnosis of Mucormycosis: Reiterating the Role of KOH Mount for Early Diagnosis

“…It has always been a challenge to diagnose this condition, and the main prerequisites for an accurate diagnosis are a high index of suspicion and recognition of host factors along with a prompt assessment of clinical manifestations [3,4]. Microscopy along with culture and histopathology demonstration of Mucorales have been the mainstay of diagnosis, albeit with less sensitivity.…”
