Introduction

Bacteremia caused by gram-positive cocci (GPC) remains challenging, particularly in assessing the risk of infective endocarditis (IE). Various scoring systems have been developed to guide the use of echocardiography. The HANDOC score was specifically designed for non-β-hemolytic streptococci (NBHS). This study aimed to validate the HANDOC score in a cohort across diverse geographic settings.

Methods

A retrospective study enrolled patients with NBHS bacteremia from 2017 to 2021 at two Spanish hospitals. Cases of IE were defined according to European Society of Cardiology 2015 modified Duke criteria. Patient characteristics were extracted from medical records for the analysis of HANDOC score validation in our cohort.

Results

Among 280 patients diagnosed with NBHS bacteremia, 31 met the modified Duke criteria for infective endocarditis (11.1%). Using a cutoff of ≥3, the HANDOC score demonstrated a sensitivity of 95%, specificity of 74% and a negative predictive value of 98%. The same metrics were analyzed with an adapted score based on positive blood culture vials, yielding similar results. Time to positivity (TTP) was analyzed with different cutoffs or by each NBHS group showing no statistically significant difference.

Conclusions

The HANDOC score is a valuable tool for decision-making in NBHS bacteriemia in a Spanish cohort. Scoring by vials may be employed for blood culture item in different clinical settings. Time-to-positivity did not show a significant difference that would justify its potential inclusion in the score.

由革兰氏阳性球菌（GPC）引起的菌血症仍然具有挑战性，特别是在评估感染性心内膜炎（IE）的风险方面。各种评分系统已经开发出来，以指导超声心动图的使用。HANDOC评分是专门为非β溶血性链球菌（NBHS）设计的。本研究旨在在不同地理环境的队列中验证HANDOC评分。方法回顾性研究纳入2017年至2021年西班牙两家医院的NBHS菌血症患者。IE病例根据欧洲心脏病学会2015年修订的杜克标准进行定义。从医疗记录中提取患者特征，对我们的队列进行HANDOC评分验证分析。结果280例NBHS菌血症患者中，31例（11.1%）符合杜克感染性心内膜炎修正标准。采用≥3的截止值，HANDOC评分的敏感性为95%，特异性为74%，阴性预测值为98%。采用基于阳性血培养瓶的适应性评分分析相同的指标，得出类似的结果。采用不同的截止点或各NBHS组对阳性时间（TTP）进行分析，差异无统计学意义。结论HANDOC评分是西班牙队列中NBHS菌血症的一个有价值的决策工具。在不同的临床环境中，血液培养项目可采用小瓶计分法。达到积极状态的时间并没有显示出显著的差异，这可以证明将其纳入得分的可能性。

The increase in global mobility has led to a higher prevalence of imported diseases in immunocompromised patients, often asymptomatic but with the potential for reactivation or severe progression. This executive summary presents the key recommendations of the consensus document developed by the Imported Pathology Study Group (GEPI-SEIMC) in collaboration with GeSIDA, GESITRA and GEIRAS (SEIMC), targeting healthcare professionals who manage immunocompromised individuals. Based on a structured narrative review, the document proposes systematic screening strategies to detect imported infections during their asymptomatic phase, clearly distinguishing them from the clinical approach in symptomatic patients. Major infections of concern are summarized. Specific guidance is provided for people living with HIV, donors and transplant recipients, oncohematologic patients, and those receiving immunosuppressive therapy. Differences in reactivation risk, preferred diagnostic methods, and therapeutic decisions in cases of latent infection are highlighted. The document underscores the need to incorporate screening into pre-treatment and pre-transplant assessments, promoting standardized protocols.

Introduction

Tuberculosis infection (TBI) in adolescents carries a high risk of progression to tuberculosis disease, yet treatment adherence remains a challenge.

Methods

Case series description.

Results

We describe a real-world experience of implementing a 12-dose weekly regimen of isoniazid (INH) and rifapentine (RPT) under video-observed therapy (VOT) in four adolescent diagnosed with TBI in a contact tracing study. This approach was chosen due to logistical and adherence concerns that made daily regimens and directly observed therapy (DOT) unfeasible. RPT was requested as a foreign medication and approved within three weeks. All patients completed treatment with 100% adherence and good tolerance.

Conclusions

Our experience supports the feasibility, tolerability, and high adherence of VOT-based weekly INH-RPT regimens in adolescents, despite regulatory barriers limiting RPT access in Europe. Broader availability of RPT and innovative adherence strategies like VOT are urgently needed to optimize TB preventive treatment in this age group.

青少年结核病感染（TBI）具有发展为结核病的高风险，但治疗依从性仍然是一个挑战。方法案例系列描述。结果：我们描述了在一项接触者追踪研究中，对四名被诊断为TBI的青少年实施每周12剂异烟肼（INH）和利福喷丁（RPT）视频观察治疗（VOT）的现实经验。选择这种方法是由于后勤和依从性问题，使得日常方案和直接观察治疗（DOT）不可行。RPT作为外来药申请，并在三周内获得批准。所有患者均以100%的依从性和良好的耐受性完成了治疗。尽管欧洲的监管障碍限制了RPT的使用，但我们的经验支持基于vot的每周INH-RPT方案在青少年中的可行性、耐受性和高依从性。迫切需要更广泛地提供RPT和创新的依从性策略，如VOT，以优化该年龄组的结核病预防治疗。

Introduction

Rubella is a generally mild viral infection, but it carries the risk of potentially severe complications, especially during pregnancy. Immunity to rubella is determined using commercial chemiluminescent immunoassays, calibrated with international standards. Despite this, discrepancies have been observed in the results obtained by different methods.

Methods

This study evaluates the performance of two chemiluminescent immunoassays (CLIAs) (Alinity i® Rubella IgG and Atellica IM® Rubella IgG) in determining rubella immunity in patient sera with low levels of anti-rubella virus (RV) IgG, using immunoblot (IB) as the reference method.

Results

101 sera were analyzed, with 72 (71.3%) classified by IB as positive and 28 (27.7%) as negative. Both assays showed 100% specificity, with sensitivity ranging from 15% for Alinity i® to 66% for Atellica IM®. The concordance between IB and CLIA Atellica was 75% when equivocal results were considered negative and 95% when considered positive, whereas for CLIA Alinity, it was 39% and 66%, respectively.

Conclusions

The evaluated CLIA showed discrepancies in determining rubella immunity, highlight inadequate standardization in the quantification of specific IgG, which could lead to errors in patient management, incorrect classification of immune status, and unnecessary revaccinations in this patient population.

风疹通常是一种轻微的病毒感染，但它有潜在的严重并发症的风险，特别是在怀孕期间。对风疹的免疫力采用商业化学发光免疫测定法测定，并按国际标准校准。尽管如此，不同方法得到的结果还是存在差异。方法以免疫印迹（IB）为参比法，评价两种化学发光免疫分析法（Alinity i®Rubella IgG和Atellica IM®Rubella IgG）在低水平抗风疹病毒（RV） IgG患者血清中风疹免疫的检测效果。结果101份血清中，IB阳性72份（71.3%），阴性28份（27.7%）。两种检测方法均显示100%的特异性，灵敏度从Alinity i®的15%到Atellica IM®的66%不等。当模棱两可的结果被认为是阴性时，IB和CLIA Atellica的一致性为75%，当被认为是阳性时，一致性为95%，而对于CLIA Alinity，一致性分别为39%和66%。结论经评估的CLIA在风疹免疫测定方面存在差异，特异性IgG定量标准化程度不高，可能导致患者管理错误、免疫状态分类错误以及该患者群体不必要的再接种。

Introduction

Enteroaggregative Escherichia coli (EAEC) is a pathotype of diarrheagenic E. coli (DEC) that causes acute and persistent diarrhea in children, HIV-infected patients and travelers. However, EAEC can also be isolated in people without diarrhea. The aim of this study was to evaluated if the EAEC bacterial load in stool samples is associated with diarrhea in comparison with asymptomatic infection.

Methods

We selected 165 stool samples (children with diarrhea: 80 and asymptomatic children: 85) that previously were identified as EAEC by Real-Time PCR for diagnostic of DEC from E. coli isolated from stool cultures. We extracted DNA from fecal samples using the cetyltrimethylammonium bromide (CTAB) method and standardized a qPCR to evaluate the bacterial load using EAEC strain 042.

Results

The detection limit of the qPCR was 10 copies of aggR gene (5 bacterias)/mg stool and the reaction efficiency was ≥93%. We found a higher bacterial load in patients with diarrhea (2.781, 95% CI: 688-6875) bacteria/mg feces] than in asymptomatic children (138, 95% CI: 75-306) bacteria/mg feces], including samples with single pathogen infection and co-infections. Among diarrheal samples, the bacterial load was higher in boys than girls and in children older than 18 months than younger.

Conclusions

EAEC load in stool samples are higher in children with diarrhea than in asymptomatic infection. This qPCR could be useful for studying the role of colonization in children living in endemic areas where the isolation of this pathogen is similar in both groups.

肠聚集性大肠杆菌（EAEC）是致泻性大肠杆菌（DEC）的一种致病型，可在儿童、艾滋病毒感染者和旅行者中引起急性和持续性腹泻。然而，EAEC也可以在没有腹泻的人群中分离出来。本研究的目的是评估与无症状感染相比，粪便样本中的EAEC细菌负荷是否与腹泻有关。方法选取165份粪便标本（腹泻患儿80份，无症状患儿85份），经实时荧光定量PCR检测为EAEC，用于从粪便培养的大肠杆菌中诊断DEC。我们使用十六烷基三甲基溴化铵（CTAB）法从粪便样本中提取DNA，并使用EAEC菌株042标准化qPCR来评估细菌负荷。结果qPCR检测限为10个aggR基因拷贝（5个细菌）/mg粪便，反应效率≥93%。我们发现腹泻患者（2.781,95% CI: 688-6875）细菌/mg粪便)的细菌负荷高于无症状儿童（138,95% CI: 75-306）细菌/mg粪便)，包括单一病原体感染和合并感染的样本。在腹泻样本中，男孩的细菌载量高于女孩，18个月以上的儿童的细菌载量高于18个月以下的儿童。结论腹泻患儿粪便中seaec含量高于无症状感染患儿。该qPCR可用于研究居住在流行地区的儿童定殖的作用，这些地区的儿童在两组中分离出的病原体相似。

Introduction

The WHO proposed to achieve hepatitis B virus (HBV) elimination by 2030, but this goal is very difficult to attain. People living with HIV (PLWH) may represent a subset where microelimination can be reached sooner. This study aimed to assess the incidence of HBV infections and changes in the prevalence of active HBV infection among PLWH in Spain.

Methods

A prospective cohort study, including all PLWH attending a university hospital in Southern Spain from January 2011 to December 2022, was conducted. Serum HBV markers (HBsAg, anti-HBs, anti-HBc) were tested at baseline and at least yearly afterwards. Incident cases were identified by anti-HBc seroconversion.

Results

Nine hundred and eighty PLWH were included. At the beginning of the study, 26 (2.7% [95% CI: 1.7–3.8%]) tested positive for HBsAg, 428 (43.7% [95% CI: 42.8–49.4%]) for anti-HBc and 386 (39.4% [95% CI: 39.8–46.3%]) for anti-HBs. After a median (Q1–Q3) follow-up of 115 (35–143) months, two new infections were documented, yielding an incidence rate of 2.24 (95% CI: 0.27–8.1)/100,000 person-years. The prevalence of active HBV infection declined from 3.4% [95% CI: 2.0–5.0%] in 2011 to 2% [95% CI: 1.0–3.0%] in 2022 (p for linear trend = 0.027). At the end of the study, 167 (24%) PLWH still were susceptible to HBV.

Conclusions

The incidence of HBV infection among PLWH in Spain is close to the WHO target. The prevalence of active HBV infection has decreased substantially during the last 12 years. These data suggest that micro-elimination of HBV/HIV infection is on the track in Spain.

世卫组织提出到2030年消除乙型肝炎病毒（HBV），但这一目标很难实现。艾滋病毒感染者（PLWH）可能是可以更快实现微消除的一个子集。本研究旨在评估西班牙PLWH中HBV感染的发生率和活动性HBV感染流行率的变化。方法对2011年1月至2022年12月在西班牙南部某大学医院就诊的所有PLWH患者进行前瞻性队列研究。血清HBV标志物（HBsAg, anti-HBs, anti-HBc）在基线和之后至少每年检测一次。通过抗- hbc血清转换来确定事件病例。结果共纳入PLWH 980例。在研究开始时，26例（2.7% [95% CI: 1.7-3.8%]）检测HBsAg阳性，428例（43.7% [95% CI: 42.8-49.4%]）检测抗hbc阳性，386例（39.4% [95% CI: 39.8-46.3%]）检测抗hbs阳性。在中位（Q1-Q3）随访115（35-143）个月后，记录了2例新感染，发病率为2.24 (95% CI: 0.27-8.1)/100,000人年。活动性HBV感染的患病率从2011年的3.4% [95% CI: 2.0-5.0%]下降到2022年的2% [95% CI: 1.0-3.0%]（线性趋势p = 0.027）。在研究结束时，167名（24%）PLWH仍对HBV易感。结论西班牙PLWH人群HBV感染率接近WHO目标。在过去12年中，活动性乙型肝炎病毒感染的流行率大幅下降。这些数据表明，西班牙正在逐步消除HBV/HIV感染。
