In a U.S. health department TB program serving primarily non-U.S.-born clients, 78% of those evaluated for latent TB infection initiated TB preventive therapy, with 71% completing treatment. Completion was lower among newly arrived migrants. A novel one-month isoniazid-rifapentine regimen (1HP) was well tolerated, with similar completion rates to conventional regimens.
在美国卫生部门结核病项目主要服务于非美国。在美国出生的客户中,有78%评估为潜伏性结核感染的人开始了结核病预防治疗,71%的人完成了治疗。新移民的完成率较低。一种新的1个月异烟肼-利福喷丁方案(1HP)耐受性良好,完成率与传统方案相似。

BACKGROUNDUnderstanding the epidemiology of invasive non-Aspergillus mold infections is essential to inform effective therapy. Robust regional studies remain scarce. This study aimed to determine the epidemiology and infection characteristics of non-Aspergillus mold infections in Australasia.METHODSA 21-center, retrospective study of proven/probable non-Aspergillus mold infections from 2016 to 2023 was conducted in Australia and New Zealand. Data collected included demographic, clinical, microbiological, treatment and outcome information until 180 days of follow-up.RESULTSOf 421 cases, 346 (82.2%) were proven infections and 315 (74.8%) were localized. Lung (n=150/421, 35.6%) was the most common site of infection. Twenty cases (4.8%) were due to >1 non-Aspergillus mold pathogen, resulting in 443 isolates altogether. Dematiaceous molds, inclusive of Lomentospora prolificans (n=96, 21.7%), Scedosporium spp. (n=87, 19.6%) and other dematiaceous molds of various genera (n=48, 10.8%), were the most common (n=231, 52.1%), followed by Mucorales (n=141, 31.8%). Common underlying conditions were hematological malignancy (n=146/421, 34.7%) and diabetes mellitus (n=122/421, 29.0%) while 68 cases (16.2%) had no comorbidities. Lymphopenia was present in 46.6% (n=196/421). One-third (n=138/421, 32.8%) received antifungal prophylaxis 30 days before non-Aspergillus mold diagnosis and L. prolificans was the most common cause of breakthrough infections (p<0.001). All-cause 90-day mortality was 31.4% (n=132/421), with higher mortality observed in L. prolificans (n=51/89, 57.3%) and Mucorales (n=56/129, 43.4%) infections.CONCLUSIONSL. prolificans, Scedosporium spp. and Mucorales are the most frequent non-Aspergillus mold pathogens in Australasia, with other emerging species and mixed infections encountered. Mortality from L. prolificans and Mucorales infections remains high.
背景了解侵袭性非曲霉霉菌感染的流行病学对有效治疗至关重要。强有力的区域研究仍然很少。本研究旨在确定澳大利亚非曲霉菌感染的流行病学和感染特征。方法对2016 - 2023年澳大利亚和新西兰地区已证实/可能的非曲霉感染病例进行回顾性研究。收集的数据包括人口统计学、临床、微生物学、治疗和结局信息,直至随访180天。结果421例中确诊感染346例(82.2%),局部感染315例(74.8%)。肺部(n=150/421, 35.6%)是最常见的感染部位。其中20例(4.8%)为非曲霉病原菌bbb101,共分离443株。腐霉属真菌以增殖性loomentospora prolificans (n=96, 21.7%)、Scedosporium spp. (n=87, 19.6%)和其他腐霉属真菌(n=48, 10.8%)最多(n=231, 52.1%),其次是Mucorales (n=141, 31.8%)。常见基础疾病为血液系统恶性肿瘤(n=146/421, 34.7%)和糖尿病(n=122/421, 29.0%),无合并症68例(16.2%)。46.6%的患者淋巴细胞减少(n=196/421)。三分之一(n=138/421, 32.8%)的患者在非曲霉菌诊断前30天接受了抗真菌预防治疗,增殖乳杆菌是最常见的突破性感染原因(p<0.001)。全因90天死亡率为31.4% (n=132/421),其中增殖乳杆菌(n=51/89, 57.3%)和毛霉菌(n=56/129, 43.4%)感染死亡率较高。在澳大拉西亚最常见的非曲霉霉菌病原体是增殖菌、塞多孢子菌和Mucorales,还会遇到其他新兴物种和混合感染。增生性乳杆菌和毛霉菌感染的死亡率仍然很高。

BACKGROUNDThe optimal frequency of repeat blood cultures in persistent febrile neutropenia (FN) remains unknown. This study aims to identify opportunities for blood culture diagnostic stewardship in persistent FN.METHODSThis is a retrospective cohort study of patients with hematology/oncology diagnoses and an FN episode >3 days. Generalized estimating equation logistic regression models were used to evaluate risk factors for new bloodstream infection (BSI) after FN day 3.RESULTSAmong 620 patients, median FN duration was 5 days and median blood culture bottles collected per patient was 12. On FN day 1, 25% of patients had a positive blood culture; on FN days 2-9, <5% of patients per day had a new organism isolated. Among 31 new organisms isolated after FN day 3, 8 (26%) were contaminants. Of 503 patients with ≥1 blood culture collected after FN day 3, 19 (4%) had a new BSI after FN day 3. FN onset in the peri-hematopoietic cell transplant (HCT) period (day -7 to +30) was associated with lower odds of new BSI after FN day 3 (OR 0.18; 95%CI [0.04-0.71]; p=0.01).Thirty-six patients died within 30 days after FN day 3, including 4 with a new BSI after FN day 3; 1 death was attributable to BSI after FN day 3.CONCLUSIONSDetection of new BSI after FN day 3 was uncommon, demonstrating low diagnostic yield of repeat blood cultures after FN day 3. FN episodes in the peri-HCT period may be a potential focus for blood culture diagnostic stewardship initiatives.
背景:持续性发热性中性粒细胞减少症(FN)的最佳重复血培养频率尚不清楚。本研究旨在确定在持续性FN中进行血培养诊断管理的机会。方法:本研究是一项回顾性队列研究,研究对象为血液学/肿瘤学诊断并在30天内发生FN发作的患者。采用广义估计方程logistic回归模型评价FN第3天后新发血流感染(BSI)的危险因素。结果620例患者中位FN持续时间为5 d,每位患者收集的中位血培养瓶为12个。FN第1天,25%的患者血培养阳性;在FN第2-9天,每天有<5%的患者分离到新的微生物。在第3天分离的31个新生物中,有8个(26%)是污染物。在FN第3天收集的503例血培养≥1的患者中,19例(4%)在FN第3天出现新的BSI。在造血细胞移植(HCT)期(-7天至+30天)FN发作与FN第3天后新BSI发生率较低相关(OR 0.18; 95%CI [0.04-0.71]; p=0.01)。36例患者在FN第3天后30天内死亡,其中4例患者在FN第3天后出现新的BSI;1例死亡在FN第3天后归因于BSI。结论FN d后新发BSI的检测不常见,FN d后重复血培养的诊断率较低。围hct期FN发作可能是血培养诊断管理倡议的潜在焦点。

Subcutaneous antibiotic administration is increasingly recognized as a valuable alternative to intravenous therapy in selected clinical contexts. It is particularly advantageous for patients with poor venous access, frail or cachectic individuals, and in outpatient or palliative care settings, when oral options are not feasible. Subcutaneous delivery of antibiotics with predominantly time-dependent activity, particularly β-lactams (eg ceftriaxone, ertapenem) and glycopeptides (teicoplanin), allows attainment of therapeutic pharmacokinetic/pharmacodynamic (PK/PD) targets comparable to intravenous administration, while maintaining stable concentrations and reducing catheter-related complications. By contrast, PK/PD benefits are limited for agents with more concentration-dependent activity, such as aminoglycosides and fluoroquinolones due to reduced peak levels and local toxicity, whereas daptomycin shows favorable exposure and target attainment with acceptable tolerability. Available evidence suggests good tolerability, although regulatory frameworks remain limited. This multidisciplinary review, authored by infectious disease specialists, clinical pharmacologists, and nurses, summarizes current clinical experience, PK/PD data, and technical aspects of subcutaneous infusion.
在某些临床情况下,皮下抗生素管理越来越被认为是静脉注射治疗的一种有价值的替代方法。对于静脉通路不良、体弱或病毒症患者,以及在门诊或姑息治疗环境中,当口服选择不可行时,它特别有利。皮下递送具有主要时间依赖性活性的抗生素,特别是β-内酰胺类(如头孢曲松、厄他培南)和糖肽类(替柯planin),可以达到与静脉给药相当的治疗药代动力学/药效学(PK/PD)目标,同时保持浓度稳定并减少导管相关并发症。相比之下,由于氨基糖苷类和氟喹诺酮类药物的峰值水平降低和局部毒性降低,具有更多浓度依赖性活性的药物的PK/PD益处有限,而达托霉素具有良好的暴露和可接受的耐受性。现有证据表明,尽管监管框架仍然有限,但耐受性良好。这篇由传染病专家、临床药理学家和护士撰写的多学科综述总结了目前的临床经验、PK/PD数据和皮下输液的技术方面。

BACKGROUNDConventional hospital antibiograms summarize aggregated resistance rates, limiting their utility for individualized antimicrobial selection. Existing statistical and machine learning models predict each phenotype separately, ignoring correlations among resistance profiles. We developed novel multi-task extreme gradient boosting (XGBoost) models utilizing structured data in electronic health records (EHRs) to predict resistance to eight antimicrobial classes simultaneously and evaluated their performance within the Veterans Health Administration (VHA).METHODSWe conducted a retrospective multicenter study of Escherichia coli and Klebsiella spp. isolates collected at 127 hospitals and >1,400 clinics from January 2017 to September 2024. Data from January 2017 to September 2023 were used for model development, while data from October 2023 to September 2024 were used for simulated prospective testing. Model performances were compared to hospital antibiograms and single-target XGBoost models.RESULTSThe training cohort included 536,252 E. coli and 246,898 Klebsiella spp. isolates; the test cohort included 75,138 and 38,015 isolates, respectively. On the test data, the multi-task model achieved overall areas under the receiver operating characteristic curve (AUROCs) of 0.779 (E. coli) and 0.810 (Klebsiella spp.), with good to excellent per-class performance (AUROCs range: 0.743-0.847). A multi-task approach improved calibration and decreased false negative rates for carbapenem resistance, while predicting individualized resistance probabilities for all target antimicrobials simultaneously ("personalized antibiograms").CONCLUSIONSA multi-task XGBoost framework can accurately predict individualized resistance profiles for common Gram-negative pathogens, outperforming conventional antibiograms and single-target models. Personalized antibiograms may enhance the selection of empiric therapy, including the detection of carbapenem resistance in low-endemicity settings.
传统的医院抗生素图总结了总耐药率,限制了它们在个体化抗菌药物选择中的效用。现有的统计和机器学习模型分别预测每种表型,忽略了抗性谱之间的相关性。我们开发了新的多任务极端梯度增强(XGBoost)模型,利用电子健康记录(EHRs)中的结构化数据同时预测对八种抗菌药物的耐药性,并在退伍军人健康管理局(VHA)中评估其表现。方法对2017年1月至2024年9月在127家医院和bbb1400家诊所采集的大肠杆菌和克雷伯氏菌进行回顾性多中心研究。2017年1月至2023年9月的数据用于模型开发,2023年10月至2024年9月的数据用于模拟前瞻性测试。将模型性能与医院抗生素图和单靶点XGBoost模型进行比较。结果培训队列包括大肠杆菌536252株、克雷伯菌246898株;试验队列分别包括75,138株和38,015株分离株。在测试数据上,多任务模型在接收者工作特征曲线(auroc)下的总体面积(大肠杆菌)为0.779,克雷伯氏菌(Klebsiella spp.)为0.810,分类性能良好至优异(auroc范围:0.743-0.847)。多任务方法改进了碳青霉烯耐药的校准并降低了假阴性率,同时预测了所有目标抗菌素的个体化耐药概率(“个体化抗生素图”)。结论多任务XGBoost框架能准确预测常见革兰氏阴性病原菌的个体化耐药谱,优于常规抗生素谱和单靶点模型。个体化抗生素图可以加强经验性治疗的选择,包括在低流行环境中检测碳青霉烯类耐药性。

Personalized antibiograms may enhance the selection of empiric therapy, including the detection of carbapenem resistance in low-endemicity settings.","PeriodicalId":10463,"journal":{"name":"Clinical Infectious Diseases","volume":"40 1","pages":""},"PeriodicalIF":11.8,"publicationDate":"2026-01-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145986280","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}

This article provides a focused update to the clinical practice guideline on the treatment and management of patients with coronavirus disease 2019 (COVID-19), developed by the Infectious Diseases Society of America. The guideline panel presents a recommendation on the use of infliximab in hospitalized adults with severe or critical COVID-19. The recommendation is based on evidence derived from a systematic literature review and adheres to a standardized methodology for rating the certainty of evidence and strength of recommendation according to the GRADE (Grading of Recommendations, Assessment, Development, and Evaluation) approach.
