| Summary: | Background and Aim:
In this era of the coronavirus disease (COVID) pandemic, new health issues appear quickly and cause an outbreak in India. Here, we focus on invasive fungal infections (IFA), namely mucormycosis, aspergillosis, and candidiasis. Hence, in this article, we focus on conventional techniques for early diagnosis of fungus to help clinicians start empirical treatment for the patient and take necessary steps thereby.
Materials and Methods:
This observational study was conducted for 1 month, from May 2021 to June 2021, on 200 patients admitted to our mucormycosis ward. Samples were first examined microscopically using potassium hydroxide (KOH) wet mounts followed by culture on sabouraud dextrose agar and the gross appearance of the growth was observed. Further identification of species was achieved through the use of lactophenol cotton blue mounts and slide culture technique.
Results:
Out of 200 patients, 65.5% were male and 34.5% female. We divided these patients into three age groups, i.e., 20–30 years (15%), 40–60 years (54%), and 60–80 years (31%). Seventy-four percent of patients presented with a history of diabetes mellitus, 50% had a history of steroids taken in their past, and 48% had a history of oxygen therapy taken at the time of COVID-19 positivity (52%) samples positive for mucormycosis. Forty-one percent were KOH-positive for Mucorales and 35.5% were culture positive. The most commonly isolated fungus was Rhizopus, followed by Mucor, Lichthemia, Aspergillus spp., and Candida spp.
Conclusion:
To improve test sensitivity and enable early diagnosis, other serum biomarkers such as galactomannan, beta-D-glucan, cryptococcal antigenemia, and blood quantitative polymerase chain reaction for Aspergillus or Mucorales should be implemented. |
