Altered immunocompetence
Altered immunocompetence in critically ill patients presents unique challenges, particularly in managing infections and immunosuppressive therapies. Immunosuppressive drugs are crucial for conditions like organ transplantation and autoimmune diseases, with their modes of action and clinical applications guiding effective therapy. Balancing immunosuppression to prevent organ rejection while minimizing infection risk is essential, emphasizing the concept of the "net state of immunosuppression."
Asplenic patients face increased risks of severe infections, particularly with encapsulated bacteria. Preventive measures such as vaccination and prophylactic antibiotics are vital, along with tailored management strategies for critical illnesses like sepsis.
Opportunistic infections are a significant concern in immunocompromised patients, requiring specialized diagnostic and therapeutic approaches. Fungal infections, including invasive aspergillosis and candidiasis, pose particular challenges and necessitate early diagnosis and appropriate antifungal therapy.
HIV-infected patients in the ICU require a multidisciplinary approach, focusing on managing HIV-related complications and opportunistic infections. Antiretroviral therapy (ART) plays a crucial role, with considerations for drug interactions and organ support.
Infectious complications post-transplantation, particularly after allogeneic hematopoietic stem cell transplantation (HSCT), demand comprehensive prevention, diagnosis, and management strategies. Adverse events of immunotherapy, such as immune-related toxicities, highlight the need for understanding and mitigating these risks to optimize cancer treatment outcomes.
