Background

West Nile virus (WNV) has emerged as a public health concern in Germany since its first detection in 2018, with evidence of expanding geographic spread. Genomic surveillance is critical for tracking viral evolution, identifying introductions, and monitoring local transmission. However, genome recovery from low-viremia samples such as those obtained through blood donor screening remains technically challenging.

Aim

To develop and validate a sensitive amplicon-based sequencing protocol optimized for WNV lineage 2 and apply it to low-titer samples to support genomic surveillance in Germany.

Methods

A novel primer scheme was designed for WNV lineage 2 and applied to 43 nucleic acid testing (NAT)-positive blood donor samples collected between 2020 and 2024. Amplicon-based sequencing performance was benchmarked against metagenomic next-generation sequencing (mNGS). Recovered genomes were subjected to phylogenomic analysis to assess viral diversity and transmission dynamics.

Results

The amplicon protocol enabled genome recovery (>70% coverage) from samples with viral loads as low as ∼10¹ RNA copies/µL, outperforming metagenomic NGS (mNGS). Of the 43 samples, 30 yielded complete or near-complete genomes. Six distinct WNV subclades (2A–2F), including German strains, were identified, indicating multiple introductions into Germany from Central Europe. Subclade 2F emerged as the dominant and widely distributed group. Berlin, Brandenburg, Saxony, and Saxony-Anhalt were identified as persistent transmission hubs.

Conclusion

This study highlights blood donors as valuable sentinels for WNV genomic surveillance. The validated amplicon-based sequencing approach enables sensitive, scalable genome recovery from low-viremia samples, and when integrated with routine blood donor screening, provides a robust framework for early detection, transmission dynamics, and public health preparedness.
背景:自2018年首次发现西尼罗河病毒(WNV)以来,该病毒已成为德国的一个公共卫生问题,有证据表明其地理传播正在扩大。基因组监测对于跟踪病毒进化、识别引入和监测本地传播至关重要。然而,从低病毒血症样本(如通过献血者筛查获得的样本)中恢复基因组在技术上仍然具有挑战性。目的:开发和验证针对西尼罗河病毒谱系2优化的基于扩增子的敏感测序方案,并将其应用于低滴度样本,以支持德国的基因组监测。方法:设计了一种新的西尼罗河病毒2系引物方案,并应用于2020 - 2024年采集的43份核酸检测(NAT)阳性献血者样本。基于扩增子的测序性能与新一代宏基因组测序(mNGS)进行了对比。对恢复的基因组进行系统基因组分析,以评估病毒多样性和传播动力学。结果:扩增子方案能够从病毒载量低至~10¹RNA拷贝/µL的样品中恢复基因组(bb0 70%覆盖率),优于宏基因组NGS (mNGS)。在43个样本中,有30个获得了完整或接近完整的基因组。确定了6个不同的西尼罗河病毒亚支(2A-2F),包括德国毒株,表明从中欧多次传入德国。亚枝2F是主要的、分布广泛的类群。柏林、勃兰登堡、萨克森和萨克森-安哈尔特被确定为持续传播中心。结论:本研究强调献血者是西尼罗河病毒基因组监测的宝贵哨兵。经过验证的基于扩增子的测序方法能够从低病毒血症样本中实现敏感、可扩展的基因组恢复,并与常规献血者筛查相结合,为早期发现、传播动态和公共卫生准备提供了一个强大的框架。

Cryptococcus neoformans and Cryptococcus gattii are World Health Organization critical and medium priority pathogens, respectively. These mainly impact people with human immunodeficiency virus residing in low- and middle-income countries, but other patient groups and settings are also affected. The high global morbidity and mortality and the limitations of current treatments provided an impetus for the development of a target product profile (TPP) for new anti-cryptococcal agents. Key attributes of the TPP include improved safety, superior (or at least comparable) activity to current treatments against all syndromes across the full disease spectrum (cryptococcal meningitis, cryptococcal pneumonia, etc.), relevance for C. neoformans and C. gattii, suitability for all age groups, oral and intravenous formulations, an acceptable treatment regimen, minimal/manageable drug-drug interactions, thermostability, and a barrier to resistance at least as high as current options. The aim of this TPP, along with the suggested discovery and development paths, is to assist all stakeholders in the development of novel cryptococcal disease treatments.
新型隐球菌和加蒂隐球菌分别是世界卫生组织的关键和中等重点病原体。这些主要影响居住在低收入和中等收入国家的人类免疫缺陷病毒感染者,但其他患者群体和环境也受到影响。全球高发病率和死亡率以及当前治疗方法的局限性为开发新的抗隐球菌药物的目标产品概况(TPP)提供了动力。TPP的关键属性包括安全性提高,与目前针对全疾病谱系(隐球菌性脑膜炎、隐球菌性肺炎等)的所有综合征的治疗方法相比具有更优(或至少相当)的活性,对新生C.和C. gatii的相关性,适用于所有年龄组,口服和静脉注射配方,可接受的治疗方案,最小/可控的药物-药物相互作用,热稳定性,以及至少与当前选择一样高的耐药屏障。TPP的目标,连同建议的发现和开发路径,是协助所有利益相关者开发新的隐球菌疾病治疗方法。

Genital herpes (GH), historically associated with herpes simplex virus type 2 (HSV-2), is changing its etiology. Since the last few decades, there has been an increase in genital infections caused by herpes simplex virus type 1 (HSV-1). In fact, in several countries, preferably in high-income regions such as North America or Western Europe, HSV-1 has become the leading cause of first-episode GH, especially among adolescents and young adults. However, the epidemiological trend varies geographically, with slower changes observed in Africa, Latin America, and Southeast Asia, where GH HSV-2 remains dominant. This epidemiological shift may be mainly due to the decline in HSV-1 seroprevalence, decreased childhood exposure to the virus, and changes in sexual practices. Despite the global decline in HSV-1 seroprevalence, GH caused by HSV-1 is rising by 1–2% annually in many areas. This review summarizes the seroprevalence of HSV-1/-2 worldwide in recent decades and discusses the changes in GH etiology and contributing factors. Despite the substantial global burden of the disease and its psychosocial impact, no vaccine or curative treatment exists. Active surveillance, health and sexual health education, and targeted interventions are vital to manage this changing landscape and to mitigate the public health issue posed by GH and HSV-1.
生殖器疱疹(GH),历史上与单纯疱疹病毒2型(HSV-2)有关,正在改变其病因。在过去的几十年里,由1型单纯疱疹病毒(HSV-1)引起的生殖器感染有所增加。事实上,在一些国家,最好是在北美或西欧等高收入地区,1型单纯疱疹病毒已成为首发生长激素的主要病因,特别是在青少年和年轻人中。然而,流行病学趋势因地而异,在非洲、拉丁美洲和东南亚观察到的变化较慢,在这些地区,2型单纯疱疹病毒仍占主导地位。这种流行病学转变可能主要是由于1型单纯疱疹病毒血清阳性率下降、儿童接触该病毒的减少以及性行为的改变。尽管全球1型单纯疱疹病毒的血清患病率有所下降,但在许多地区,1型单纯疱疹病毒引起的生长激素仍以每年1%至2%的速度上升。本文综述了近几十年来全球HSV-1/ 2的血清患病率,并讨论了GH的病因和影响因素的变化。尽管这一疾病在全球造成了沉重的负担及其社会心理影响,但目前还没有疫苗或治疗方法。积极监测、健康教育和有针对性的干预措施对于管理这种不断变化的情况和减轻GH和HSV-1造成的公共卫生问题至关重要。

Background

Some studies have suggested an association between Enterococcus faecalis blood stream infection (BSI) and colorectal cancer (CRC) suggesting that screening for CRC could be reasonable. However, these studies were limited by small numbers with low generalizability.

Methods

Danish nationwide registries were used to identify patients with first-time E. faecalis BSI from 2010 to 2021 without previous colorectal neoplasia (CRN). Age-, sex- and calendar-matched comparators from the general population were identified (1:5). We estimated the six-month cumulative incidence of CRC and CRN and a multivariable adjusted Cox analysis was used for relative comparison between groups.

Results

We identified 4664 patients with E. faecalis BSI (median age: 74.9 years, 73.4% males) and 23,320 comparators from the general population. For patients with E. faecalis BSI the six-month incidence of CRC was 0.45% (95% CI: 0.28–0.72%) and of CRN 2.34% (95% CI: 1.88–2.88). For matched comparators the incidence of CRC was 0.12% (95% CI: 0.08–0.17) and of CRN 0.48% (95% CI: 0.39–0.57). In adjusted analysis, patients with E. faecalis BSI had a higher HR of CRC (HR=3.70 (95% CI: 1.91–7.19) and CRN (HR=4.64 (95% CI: 3.40–6.34) than matched comparators. The six-month mortality was 36.3% in patients with E. faecalis BSI while this was 1.7% among comparators.

Conclusion

In patients with first-time E. faecalis BSI the six months incidence of CRC was around 0.5% and 2.3% for the diagnosis of CRN, which were 3–4 times higher than in a matched cohort from the general population. Nevertheless, the absolute risks do not justify systematic screening for CRC or CRN in patients with E. faecalis BSI.
背景:一些研究表明粪肠球菌血流感染(BSI)与结直肠癌(CRC)之间存在关联,提示CRC筛查可能是合理的。然而,这些研究数量较少,通用性较低。方法:采用丹麦全国登记系统,对2010 -2021年无结直肠肿瘤(CRN)的首次粪肠杆菌BSI患者进行鉴定。从一般人口中找出年龄、性别和日历相匹配的比较者(1:5)。我们估计了6个月CRC和CRN的累积发病率,并使用多变量校正Cox分析进行组间的相对比较。结果:我们从普通人群中确定了4,664例粪肠杆菌BSI患者(中位年龄:74.9岁,73.4%为男性)和23,320例比较者。粪肠杆菌BSI患者6个月CRC发生率为0.45% (95% CI: 0.28-0.72%), CRN发生率为2.34% (95% CI: 1.88-2.88)。对于匹配的比较者,CRC的发生率为0.12% (95% CI: 0.08-0.17), CRN的发生率为0.48% (95% CI: 0.39-0.57)。在校正分析中,粪肠杆菌BSI患者的CRC HR (HR=3.70 (95% CI: 1.91-7.19)和CRN (HR=4.64 (95% CI: 3.40-6.34)高于匹配的比较者。粪肠杆菌BSI患者的6个月死亡率为36.3%,而对照组为1.7%。结论:在首次发生粪肠杆菌BSI的患者中,诊断为CRN的6个月CRC发病率约为0.5%和2.3%,是普通人群匹配队列的3-4倍。然而,绝对风险并不能证明系统筛查粪肠杆菌BSI患者的CRC或CRN是合理的。

Objectives

Candidemia is a severe complication in critically ill and immunocompromised patients, and is associated with high morbidity and mortality. While early fungal clearance may improve outcomes, the association between follow-up blood culture (FUBCs) results and clinical outcomes remains insufficiently explored. This sub-analysis of the ECMM Candida III study investigates predictors of persistent candidemia and the impact of positive FUBC results on clinical outcomes.

Methods

The multicenter ECMM Candida III study enrolled adults with culture-proven candidemia from 60 European centers (2018–2019). This sub-analysis included patients with at least one FUBC result reported (n = 258; 40.8%). Statistical analysis used SPSS 29 and R. Binary logistic regression was used to identify predictors of persistent candidemia. To assess mortality risk factors, Cox proportional hazards regression models were constructed.

Results

Of 258 patients, 52 (20.2%) had persistent candidemia based on positive FUBCs (median duration of candidemia 6 days). Utilization of echinocandins as first line treatment was less frequent (61.5% vs. 78.2%; p=0.014) in those with positive FUBCs. Mortality was significantly higher in the FUBC-positive group (50% vs. 32%; p=0.016). In the multivariable logistic regression model, lower EQUAL Candida Scores, reflecting reduced adherence to guideline-recommended management, were independently associated with persistent candidemia (OR 0.003, 95% CI 0.0002–0.07; p<0.001). Univariable Cox regression identified persistent candidemia ≥5 days (HR 2.16; 95% CI 1.33–3.53; p= 0.002) as a significant predictor of mortality. In the multivariable Cox regression model, intensive care unit (ICU) admission (HR 1.59, 95% CI 1.02–2.50; p= 0.039) and persistent candidemia ≥5 days (HR 2.06, 95% CI 1.26–3.37; p= 0.004) remained independent predictors of mortality.

Conclusion

Persistent candidemia was predicted by poor adherence to treatment guidelines, as shown by low EQUAL Candida Scores, particularly due to the lack of initial echinocandin use. After controlling immortal time bias, persistent candidemia ≥5 days and ICU admission remained independent predictors of mortality in the multivariable model.
目的:念珠菌病是危重症和免疫功能低下患者的严重并发症,具有高发病率和高死亡率。虽然早期真菌清除可能改善预后,但随访血培养(fubc)结果与临床结果之间的关系仍未得到充分探讨。ECMM念珠菌III研究的亚分析研究了持续性念珠菌的预测因素以及FUBC阳性结果对临床结果的影响。方法:多中心ECMM念珠菌III研究招募了来自欧洲60个中心(2018-2019)的培养证实念珠菌病的成人。该亚组分析包括至少有一个报告的FUBC结果的患者(n = 258; 40.8%)。采用SPSS 29和SPSS r进行统计学分析。采用二元logistic回归确定持续性念珠菌的预测因素。为评估死亡危险因素,构建Cox比例风险回归模型。结果:258例患者中,52例(20.2%)存在基于fubc阳性的持续性念珠菌病(念珠菌病中位持续时间6天)。在fubc阳性的患者中,使用棘白菌素作为一线治疗的频率较低(61.5%比78.2%;p=0.014)。fubc阳性组的死亡率显著高于对照组(50% vs. 32%; p=0.016)。在多变量logistic回归模型中,较低的EQUAL念珠菌评分,反映了对指南推荐管理的依从性降低,与持续性念珠菌血症独立相关(OR 0.003, 95% CI 0.0002 - 0.07)。结论:持续性念珠菌血症的预测与对治疗指南的依从性较差有关,如较低的EQUAL念珠菌评分所示,特别是由于缺乏初始使用棘白菌素。在控制存活时间偏差后,在多变量模型中,持续念珠菌≥5天和入住ICU仍然是死亡率的独立预测因子。资金来源:研究者发起的研究基金从Scynexis和Mundipharma获得,以支持该研究。

Objectives

We evaluated the efficacy, safety and impact on viral reservoir of rapid bictegravir/emtricitabine/tenofovir alafenamide (BIC/FTC/TAF) initiation during primary HIV infection (PHI).

Methods

Multicenter, single-arm clinical trial in participants with PHI of <3 months (seroconversion or incomplete serological pattern), starting BIC/FTC/TAF in 6 Spanish centers between January-2021 and September-2022. Primary endpoint was proportion of participants with viral load (VL)<50 copies/mL at 48-weeks on the Intention-to-treat-exposed population (ITTe). Cases were compared with randomly-matched retrospective PHI controls, starting other 3-drug Integrase-Strand-Transfer-inhibitor-based regimens. Reservoir was evaluated in PHI cases by Intact Proviral DNA Assay (IPDA).

Results

We included 64 participants, 94% cis-male, aged 32 (26;41) years.; 78% men-who-have-sex-with-men. At BIC/FTC/TAF initiation, Fiebig stages were II (14%), III (11%); IV (5%), V (54%) and VI (16%); VL was 496,520 (110,000;1,285,000) copies/mL; 62% were subtype B; median (IQR) CD4 T cell count was 406 (322;535) cells/µL; 6% had active hepatitis B virus co-infection. All participants started BIC/FTC/TAF at first specialist consultation. 81% (ITTe) and 93% (On-Treatment, OT) had VL<50 copies/mL at 48-weeks. 72% had adverse events, only 3% were grade 3/4; 91% were not-related, none led to BIC/FTC/TAF-discontinuation. 92% of controls (OT) had VL<50 copies/mL at 48-weeks (p=0.914), 11% (17%) modified initial antiretroviral regimen (p>0.001). Intact and defective proviral DNA levels significantly decreased at 48-weeks.

Conclusions

BIC/FTC/TAF showed rapid viral decay, high suppression rates, good tolerability, and reservoir decline in PHI, making it an appealing regimen in this setting.
目的:我们评估了原发性HIV感染(PHI)期间快速启动比替重力韦/恩曲他滨/替诺福韦α胺(BIC/FTC/TAF)治疗的有效性、安全性和对病毒库的影响。方法:对PHI患者进行多中心单臂临床试验,结果:我们纳入64例患者,94%为顺式男性,年龄32(26;41)岁。men-who-have-sex-with-men 78%。在BIC/FTC/TAF启动时,5个大阶段分别为II (14%), III (11%);IV(5%)、V(54%)、VI (16%);VL为496,520(110,000;1,285,000)拷贝/mL;B亚型占62%;中位数(IQR) CD4 T细胞计数为406(322;535)个细胞/µl;6%有活动性乙型肝炎病毒合并感染。所有参与者在第一次专家咨询时开始BIC/FTC/TAF。81% (ITTe)和93% (On-Treatment, OT)的VL0.001)。完整和有缺陷的原病毒DNA水平在48周时显著下降。结论:BIC/FTC/TAF在PHI中表现出快速的病毒衰减、高抑制率、良好的耐受性和储层下降,使其成为一种有吸引力的治疗方案。

This review outlines recent trends on invasive meningococcal disease (IMD) discussed at the latest meeting of the Global Meningococcal Initiative (GMI). There has been a re-emergence of the Hajj strain sublineage (serogroup W; ST-11 clonal complex), with travel to the Kingdom of Saudi Arabia being a critical factor in transmission. The epidemiology of IMD has also changed following the COVID-19 pandemic, with annual IMD cases increasing in many countries. For example, the highest number of IMD cases since 2014 was reported in the USA in 2023–2024. Atypical presentations of IMD have been prominent irrespective of the pandemic. For instance, an increase in cases of meningococcal epiglottitis has been reported in France in 2022–2023 (serogroups W and Y). When considering vaccination, the GMI has identified a need for broader meningococcal serogroup B (MenB) immunisation owing to the potential impact of the vaccines on reducing IMD incidence caused by other serogroups than MenB. There is also a case for using MenB vaccination to protect against Neisseria gonorrhoeae infection based on initial evidence, albeit further studies will need to be conducted.
这篇综述概述了最近在全球脑膜炎球菌倡议(GMI)会议上讨论的侵袭性脑膜炎球菌病(IMD)的最新趋势。朝觐毒株亚谱系(W血清群;ST-11克隆复合体)再次出现,前往沙特阿拉伯王国旅行是传播的关键因素。在2019冠状病毒病大流行之后,IMD的流行病学也发生了变化,许多国家每年的IMD病例都在增加。例如,自2014年以来,美国报告的IMD病例数最多的是2023-2024年。无论大流行如何,IMD的非典型表现都很突出。例如,据报道,法国2022-2023年脑膜炎球菌性会厌炎病例有所增加(血清组W和Y)。在考虑疫苗接种时,全球免疫倡议已确定需要更广泛的脑膜炎球菌B血清组(MenB)免疫接种,因为疫苗对减少由B血清组以外的其他血清组引起的IMD发病率有潜在影响。根据初步证据,也有使用b型脑膜炎球菌疫苗预防淋病奈瑟菌感染的案例,尽管还需要进行进一步的研究。
