Clinical Application of Cytokine Adsorption Technique in AIDS Patients With Severe Pneumonia and/or Septic Shock

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

Detailed Description
-----------------
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.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Cytokine Adsorption Combined with Standard Treatment Group<br>This group receives cytokine adsorption combined with standard treatment, specifically via hemoperfusion using the standard 211 protocol: two hemoperfusions within the first 24 hours, followed by one hemoperfusion daily. Each hemoperfusions session does not exceed 6 hours, lasting a total of 3 days. All patients also undergo blood perfusion treatment with the addition of a plasma separator. | Device: Cytokine Adsorption<br>* During treatment with cytokine adsorption cartridge, the patient's blood is passed through these cartridges, which contain substances that can adsorb specific cytokines. Excess cytokines are captured and removed by these substances, and then the cleansed blood is returned to the patient's body.<br>|
| Standard Treatment Group<br>This group receives only standard treatment . Standard treatment includes symptomatic supportive therapy, etiological therapy, fluid resuscitation, application of vasopressors, and non-invasive or invasive ventilation therapy. | |
