No regimen showed statistically significant superiority over TMP-SMX in direct comparison. In the network meta-analysis, clindamycin/primaquine was ranked the best (surface under the cumulative ranking curve, 0.8), followed by intravenous pentamidine (0.8) and TMP-SMX (0.8) regarding treatment failure. Regarding all-cause mortality, TMP-SMX was superior to atovaquone in direct comparison, but no treatment was superior in the full network analysis. Dapsone-TMP (0.7) and intravenous pentamidine (0.8) were ranked the highest for mortality reduction. For safety and tolerability, comparator drugs consistently outperformed TMP-SMX, with significant reductions in toxicity observed for dapsone-TMP, inhaled pentamidine, and atovaquone. Inhaled pentamidine (0.9) was the best tolerated, followed by trimetrexate (0.8) and atovaquone (0.8).</p><p><strong>Conclusions: </strong>We conclude that TMP-SMX should be reassessed as the standalone first-line therapy for PCP in PWH, given the better tolerability and comparable efficacy of other treatments. In places with access to alternative drugs for PCP treatment, our analysis suggests that alternative regimens may offer comparable effectiveness, providing flexibility to use alternative treatments when comorbidities necessitate it.</p>","PeriodicalId":10444,"journal":{"name":"Clinical Microbiology and Infection","volume":" ","pages":""},"PeriodicalIF":10.9,"publicationDate":"2024-12-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142892460","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Evidence on risk factors associated with encephalitis is scarce and hampered by the absence of population-based case-control studies.
