Summary

Immunosuppression, including that related to Human Immunodeficiency Virus (HIV) infection, increases the risk of opportunistic parasitic and fungal infections. Early diagnosis and treatment are crucial for managing these severe infections in immunocompromised patients.

Area of Science:

  • Medical Microbiology
  • Infectious Diseases
  • Immunology

Background:

  • Immunosuppression, whether associated with Human Immunodeficiency Virus (HIV) infection or other causes, predisposes individuals to opportunistic infections.
  • Opportunistic parasitic and fungal pathogens can cause severe and life-threatening conditions in immunocompromised hosts.

Purpose of the Study:

  • To analyze the spectrum of opportunistic parasitic and fungal agents in immunocompromised individuals.
  • To describe the clinical manifestations and severity of these infections.
  • To highlight the emergence of new pathogenic agents.

Main Methods:

  • Retrospective study over 9 years.
  • Analysis of parasitic and fungal infections in patients with various forms of immunosuppression.

  • Case identification and diagnosis of specific pathogens.
  • Main Results:

    • In 31 HIV-infected patients: Cryptosporidium (7), Isospora belli (2), Enterocytozoon bieneusi (1), Pneumocystis pneumonia (6), cerebral toxoplasmosis (6), meningo-cerebral cryptococcosis (1).
    • In other immunocompromised patients: Systemic candidiasis (13 leukaemic patients), intestinal anguilluliasis (5 patients on long-term corticosteroids), Kala azar (1 patient on corticosteroids), disseminated aspergillosis (1 child with Chediak-Higashi syndrome), gingivo-labial fusariosis (1 leukaemic patient).

    Conclusions:

    • The emergence of novel parasitic and fungal agents in immunocompromised individuals necessitates improved understanding.
    • Enhanced early diagnosis and effective treatment strategies are critical for managing these opportunistic infections.
