What this trial studies

This open-label, prospective clinical study aims to evaluate the efficacy and safety of trimethoprim/sulfamethoxazole as a preventive treatment for Pneumocystis jirovecii pneumonia in patients diagnosed with autoimmune inflammatory rheumatic diseases. The study will collect and analyze baseline characteristics of participants receiving this medication and follow up to assess outcomes. Additionally, a stratified analysis will identify which patients are most likely to benefit from this preventive approach based on their risk factors.
