Fungal Surveillance in Bangladesh

Invasive Fungal Infections Clinical Trial

Official title: Surveillance for Invasive Fungal Infections in Selected Hospitals in Dhaka City, Bangladesh

Status Recruiting

Clinical Trial Summary

This will be an exploratory descriptive study designed to conduct surveillance for the identification of invasive fungal pathogens among hospitalized patients in Bangladesh at two tertiary care acute-level hospitals. including the Dhaka Medical College Hospital, the Dhaka Hospital of icddr,b, and the National Institute of Cancer Research Hospital (NICRH). Respiratory samples, blood, urine, cerebrospinal fluid, surgical wound infection swabs, and other samples including biopsy tissue specimens will be obtained at intensive care units, general medicine and surgery wards, post-operative care, etc. The collected specimens will be sent to the clinical microbiology laboratories of the surveillance hospitals or to the pathology laboratory (biopsy tissue specimens) to test for Aspergillus, Histoplasms, Candida, Pneumocystis, Cryptococcus, and Mucormycetes. The lab. methods will include microscopy, staining, culture, and biochemical tests mainly and if feasible then some specimens may undergo molecular or immunological methods.

Clinical Trial Description

1. Burden:

Over 300 million people worldwide are infected with a deadly fungal infection, with 25 million at high risk of death or blindness. Population and disease demographics are used to calculate the worldwide burden of fungal diseases (age, gender, HIV infection, asthma, etc).

Given the growing number of immunocompromised individuals especially among hospitalized patients who are at increased risk for invasive fungal infections, fungal illnesses require more attention than ever before. The importance of fungal diseases contributing to worldwide morbidity and mortality is emphasized. To assess the burden of these diseases more precisely, long-term, sustainable monitoring systems for fungal diseases, as well as better noninvasive and reliable diagnostic methods, are required.

Even though most deaths from fungal illnesses are preventable, they are still a neglected topic by public health authorities. Other health issues, such as asthma, AIDS, cancer, organ transplantation, and corticosteroid therapy, can result in serious fungal infections. Antifungal therapy can be started right away if a correct diagnosis is made early. Recent global estimates have found 3,000,000 cases of chronic pulmonary aspergillosis, ~223,100 cases of cryptococcal meningitis complicating HIV/AIDS, ~700,000 cases of invasive candidiasis, ~500,000 cases of Pneumocystis jirovecii pneumonia, ~250,000 cases of invasive aspergillosis, ~100,000 cases of disseminated histoplasmosis, over 10,000,000 cases of fungal asthma and ~1,000,000 cases of fungal keratitis occur annually.

2. Knowledge gap:

Currently, there is no ongoing national surveillance system to detect invasive fungal pathogens or serious health threats. Hence, there is inadequate data on the burden, types, and diversity of fungal species in particular among hospitalized patients in Bangladesh. Some noteworthy issues affecting the proper diagnosis of invasive fungal pathogens in Bangladesh are an inadequate number of trained laboratory personnel to diagnose fungal diseases, only a few healthcare facilities performing fungal culture, insufficient awareness about severe fungal infections, lack of prioritization for fungal disease surveillance in healthcare delivery, lack of understanding about utilization of surveillance data to guide diagnosis and treatment, lack of antifungal drug stewardship and diagnostic stewardship and significant logistical challenges to ensure adequate biosecurity for diagnosis of and prevention against severe fungal infections.

Relevance:

Investigators need to take the necessary steps that will gradually lead to the establishment of a national surveillance system for invasive fungal pathogens, increase the generation of country-representative fungal surveillance data, improve surveillance data usage and reporting, and enhance IPC activities in Bangladesh.

Objectives:

To identify hospitalized patients infected with invasive fungal pathogens.

Description of the research project:

Methods:

This will be an exploratory descriptive study designed to conduct surveillance for the identification of invasive fungal pathogens among hospitalized patients in Bangladesh at two tertiary care acute-level hospitals.

The primary outcomes to be measured in this study:

The proportion of laboratory-identified invasive fungal pathogens among hospitalized patients. ;
