Abstract:
In this report we describe the clinical and laboratory profiles of different opportunistic infections (OIs) among 125 immunocompromised patients admitted to a referral hospital in the eastern part of India. Different pathogens were isolated, identified and characterized using the laboratory gold standard methods. Oral candidiasis (88%) was found to be the most common OI, followed by tuberculosis (57%), enteropathogenic Vibrio (47%), cytomegalovirus infection (45%), cryptosporidial diarrhea (43%), Escherichia coli infection (42%) and other infections among the study subjects. Statistical analysis of the case studies shows 120/cumm median CD4+ blood cell count, and the OIs showed an inversely proportional occurrence to the CD4+ count of the immunocompromised patients. The spectrum and frequency of certain OIs highlight the urgency of studying HIV/AIDS in resource-limited countries where locally specific disease patterns may be observed. The purpose of the present investigation was the identification of such opportunistic pathogens, as we feel the HIV epidemic can be more effectively managed if physicians and health planners are aware of this information.
Insights
Opportunistic infections (OIs) are common in immunocompromised patients in India, with oral candidiasis being the most frequent. OI occurrence inversely correlates with CD4+ blood cell counts, emphasizing the need for localized HIV/AIDS research.
Area of Science:
- Infectious Diseases
- Immunology
- Public Health
Background:
- Opportunistic infections (OIs) pose a significant threat to immunocompromised individuals.
- Understanding the spectrum of OIs is crucial for managing immunocompromised patient populations, especially in resource-limited settings.
Purpose of the Study:
- To describe the clinical and laboratory profiles of opportunistic infections in immunocompromised patients in Eastern India.
- To identify common opportunistic pathogens and their relationship with CD4+ cell counts.
Main Methods:
- Clinical and laboratory data were collected from 125 immunocompromised patients.
- Pathogen isolation, identification, and characterization were performed using gold standard laboratory methods.
Main Results:
- Oral candidiasis (88%) was the most prevalent OI, followed by tuberculosis (57%) and enteropathogenic Vibrio (47%).
- A median CD4+ blood cell count of 120/cumm was observed.
- Opportunistic infections showed an inverse correlation with CD4+ cell counts.
Conclusions:
- The study highlights a specific pattern of OIs in immunocompromised patients in India.
- Awareness of these locally prevalent opportunistic pathogens is essential for effective HIV/AIDS management and public health planning in resource-limited regions.

Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
