Masur – HIV/AIDS Related Infections

Managing HIV-related opportunistic infections in the intensive care unit requires a nuanced understanding of specific immunologic deficits. Pneumocystis, Toxoplasmosis, and Cryptococcal meningitis remain the most critical infections, with susceptibility strongly correlated to CD4 counts and viral loads. Diagnostic protocols must balance the high sensitivity of PCR with the necessity of clinical correlation, as positive results often indicate colonization rather than active disease. Effective management involves targeted therapies, such as corticosteroids for severe Pneumocystis and serial lumbar punctures to control intracranial pressure in Cryptococcal meningitis. Clinicians must also remain vigilant for Immune Reconstitution Inflammatory Syndrome (IRIS) following the initiation of antiretroviral therapy, which can trigger inflammatory responses to latent pathogens. While HIV-related care has evolved, these infections persist, necessitating clinical expertise to distinguish between opportunistic pathogens and non-infectious complications like heart failure or pulmonary emboli.
