The role of trimethoprim/sulfamethoxazole in preventing opportunistic infections in systemic lupus erythematosus patients receiving low-level immunosuppressive treatment: an open-label, randomized, controlled trial.
Objective: Systemic lupus erythematosus (SLE) patients receiving immunosuppressive therapy are at risk for opportunistic infections (OIs), particularly Pneumocystis pneumonia (PCP). This study aimed to evaluate the effectiveness of trimethoprim/sulfamethoxazole (TMP/SMX) as primary prophylaxis against OIs and its adverse effects in SLE patients receiving low-level immunosuppressive treatment in a real-world setting.
Methods: This open-label randomized controlled trial enrolled SLE patients receiving low-level immunosuppressive treatment at Ramathibodi Hospital between May 2021 and December 2022. Patient demographics and relevant clinical data were collected. Participants were randomized 1:1 to receive TMP/SMX or no prophylaxis, with dose adjustments according to renal function. The incidences of TMP/SMX-sensitive OIs and adverse events were monitored for 12 months post-enrollment.
Results: The trial was terminated early due to a high rate of adverse drug reactions (ADRs) associated with TMP/SMX. In total, 138 SLE patients receiving low-level immunosuppressive treatment were enrolled. Most patients (98.4%) were in disease remission. No TMP/SMX-sensitive OIs were observed in either group during the 12-month follow-up period. Among individuals receiving TMP/SMX, 10/70 (14.3%) developed ADRs. Of these 10 patients, eight experienced grade 1 ADRs, and two had grade 3 ADRs; all declined to resume prophylaxis. There were no deaths in the study.
Conclusions: During the 12-month follow-up period, no TMP/SMX-sensitive OIs occurred in SLE patients receiving low-level immunosuppressive therapy, suggesting that primary prophylaxis with TMP/SMX may not significantly benefit this population. The high rate of ADRs observed underscores the need for clinicians to carefully consider the risks and benefits of TMP/SMX prophylaxis in these patients.
期刊介绍：
Clinical and Experimental Medicine (CEM) is a multidisciplinary journal that aims to be a forum of scientific excellence and information exchange in relation to the basic and clinical features of the following fields: hematology, onco-hematology, oncology, virology, immunology, and rheumatology. The journal publishes reviews and editorials, experimental and preclinical studies, translational research, prospectively designed clinical trials, and epidemiological studies. Papers containing new clinical or experimental data that are likely to contribute to changes in clinical practice or the way in which a disease is thought about will be given priority due to their immediate importance. Case reports will be accepted on an exceptional basis only, and their submission is discouraged. The major criteria for publication are clarity, scientific soundness, and advances in knowledge. In compliance with the overwhelmingly prevailing request by the international scientific community, and with respect for eco-compatibility issues, CEM is now published exclusively online.
