Observing the Real-World Application Effectiveness of Cytokine Immune Adsorption Technology in AIDS Patients with Severe Pneumonia or septic shock.

This is a prospective, single-center, non-randomized, clinical observational cohort study primarily focused on observing the clinical effects of cytokine adsorption technology in patients with AIDS complicated by severe pneumonia and/or septic shock. Based on the real-world application of cytokine adsorption technology in AIDS patients with severe pneumonia or septic shock, the study divides patients into two groups: one receiving cytokine adsorption combined with standard treatment, and another receiving standard treatment only. The study aims to observe the impact of these two different treatment strategies on clinical outcomes.

Inclusion Criteria:

1. Confirmed HIV infection;

2. Progression to AIDS stage: CD4+ count <200 cells/ul and/or occurrence of AIDS opportunistic infections;

   1. The criteria for severe pneumonia diagnosis refer to the 2021 ATS (American Thoracic Society) and IDSA (Infectious Diseases Society of America) guidelines for the treatment of community-acquired pneumonia;
   2. The criteria for septic shock refer to the Chinese Society of Critical Care Medicine's "Chinese Guidelines for the Emergency Treatment of Sepsis/Septic Shock (2018).

Exclusion Criteria:

1. Coexisting central nervous system lesions, severe liver disease, or cirrhosis;
2. Concurrent AIDS-related or unrelated tumors;
3. Women who are pregnant or breastfeeding;
