Abstract:
Fungi are major contributors to the opportunistic infections that affect patients with HIV/AIDS. Systemic infections are mainly with Pneumocystis jirovecii (pneumocystosis), Cryptococcus neoformans (cryptococcosis), Histoplasma capsulatum (histoplasmosis), and Talaromyces (Penicillium) marneffei (talaromycosis). The incidence of systemic fungal infections has decreased in people with HIV in high-income countries because of the widespread availability of antiretroviral drugs and early testing for HIV. However, in many areas with high HIV prevalence, patients present to care with advanced HIV infection and with a low CD4 cell count or re-present with persistent low CD4 cell counts because of poor adherence, resistance to antiretroviral drugs, or both. Affordable, rapid point-of-care diagnostic tests (as have been developed for cryptococcosis) are urgently needed for pneumocystosis, talaromycosis, and histoplasmosis. Additionally, antifungal drugs, including amphotericin B, liposomal amphotericin B, and flucytosine, need to be much more widely available. Such measures, together with continued international efforts in education and training in the management of fungal disease, have the potential to improve patient outcomes substantially.
Insights
Fungal infections remain a significant threat for individuals with HIV/AIDS, especially in resource-limited settings. Improved diagnostics and wider antifungal drug access are crucial for better patient outcomes.
Area of Science:
- Mycology
- Infectious Diseases
- Immunology
Background:
- Fungal infections are common opportunistic infections in patients with Human Immunodeficiency Virus/Acquired Immunodeficiency Syndrome (HIV/AIDS).
- Key systemic fungal infections include pneumocystosis, cryptococcosis, histoplasmosis, and talaromycosis.
- While antiretroviral therapy has reduced fungal infection incidence in high-income countries, challenges persist in resource-limited settings due to advanced HIV and treatment adherence issues.
Purpose of the Study:
- To highlight the persistent burden of systemic fungal infections in HIV/AIDS patients.
- To emphasize the need for improved diagnostic and therapeutic strategies for fungal diseases in HIV/AIDS care.
- To advocate for increased accessibility of diagnostic tools and antifungal medications.
Main Methods:
- Review of current literature on fungal infections in HIV/AIDS.
- Analysis of factors contributing to increased fungal infection risk in specific populations.
- Identification of existing and needed interventions for fungal disease management.
Main Results:
- Systemic fungal infections continue to affect HIV/AIDS patients, particularly those with low CD4 counts or treatment challenges.
- Diagnostic and treatment gaps exist for several key fungal infections, including pneumocystosis, talaromycosis, and histoplasmosis.
- Antiretroviral drug resistance and poor adherence exacerbate the risk and impact of these infections.
Conclusions:
- Affordable, rapid point-of-care diagnostic tests are urgently required for pneumocystosis, talaromycosis, and histoplasmosis.
- Wider availability of essential antifungal drugs like amphotericin B and flucytosine is critical.
- International collaboration on education and training in fungal disease management can significantly improve patient outcomes.

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.
