The Haematologist and the Infective Complications of HIV Infection

Area of Science:

• Hematology
• Infectious Diseases
• Oncology

Background:

• Patients with acquired immunodeficiency syndrome (AIDS) frequently exhibit hematological abnormalities due to HIV infection and opportunistic infections.
• These abnormalities can mimic other hematological disorders, necessitating careful diagnostic evaluation.

Purpose of the Study:

• To highlight the importance of hematological examination in diagnosing opportunistic infections and AIDS-related malignancies.
• To guide hematologists in identifying characteristic findings to avoid misdiagnosis.

Main Methods:

• Review of peripheral blood and bone marrow findings in patients with AIDS.
• Identification of specific opportunistic infections and viral associations with hematological malignancies.

Main Results:

• Characteristic findings include increased plasma cells and lymphoid aggregates, which can be mistaken for plasma cell dyscrasias or lymphomas.
• Bone marrow examination aids in diagnosing infections like Mycobacterium avium intracellulare, tuberculosis, cryptococcosis, histoplasmosis, and leishmaniasis.
• Epstein-Barr virus and human herpes virus 8 are implicated in lymphomagenesis and Kaposi's sarcoma.

Conclusions:

• Hematological assessment is vital for diagnosing opportunistic infections and AIDS-related lymphomas, including Burkitt's lymphoma, Hodgkin's disease, and Kaposi's sarcoma.
• Accurate interpretation of blood and bone marrow morphology is essential for appropriate patient management.
