    背景:美国胃肠内镜学会建议在原发性硬化性胆管炎(PSC)的内镜逆行胰胆管造影术(ERCP)之前使用预防性抗生素。我们使用全国数据评估了这种方法对ERCP后结局发生率的影响。
    方法:使用2015-2021年全国住院患者样本数据和相关ICD-10代码,我们分析了接受ERCP的PSC成人住院情况,有和没有抗生素预防。使用分层多变量逻辑回归分析评估预防性抗生素使用与ERCP后并发症(包括败血症)之间的关联。急性胆管炎,和急性胰腺炎。
    结果:我们分析了32,972例涉及ERCP的PSC住院,12,891例(39.1%)患者在ERCP前接受抗生素治疗(病例),20,081例(60.9%)作为对照。病例年龄大于对照组(平均年龄:64.2±8.6vs.61.3±6.1年;P=0.020)。与对照组相比,接受抗生素预防的住院治疗的男性人群较高(7,541(58.5%)与11,265(56.1%);P<0.001)和更高的合并症负担(Charlson合并症指数评分≥2:5,867(45.5%)的病例与对照组为8,996(44.8%);P=0.01)。ERCP后败血症的发生率为19.1%(6,275),病例中有2,935例(22.8%),而对照组中有3,340例(16.6%)。抗生素预防并没有显著改善败血症的几率(aOR:0.85;95%CI:0.77-1.09;P=0.179)。记录了大约2,271例(6.9%)急性胆管炎和5,625例(17.1%)急性ERCP后胰腺炎。调整多个变量后,发生胆管炎的几率无显著差异(aOR:0.87;95%CI:0.98~1.45;P=0.08).然而,抗生素预防与急性ERCP后胰腺炎的比值比显著降低相关(aOR:0.61;95%CI:0.57~0.66;P<0.001).
    结论:在PSC住院期间预防性使用抗生素与ERCP术后胰腺炎的几率显著降低相关。抗生素预防并不能改善ERCP后败血症或胆管炎的几率。预防性使用抗生素应个体化,考虑到它们的抗感染益处和对肝病生化标志物的潜在影响。
    BACKGROUND: The American Society for Gastrointestinal Endoscopy recommends prophylactic antibiotics before endoscopic retrograde cholangiopancreatography (ERCP) in primary sclerosing cholangitis (PSC). We assessed the impact of this approach on the incidence of post-ERCP outcomes using nationwide data.
    METHODS: Using 2015-2021 Nationwide Inpatient Sample data and relevant ICD-10 codes, we analyzed adult hospitalizations for PSC who underwent ERCP, with and without antibiotic prophylaxis. Hierarchical multivariate logistic regression analysis was used to assess the association between prophylactic antibiotic use and post-ERCP complications including sepsis, acute cholangitis, and acute pancreatitis.
    RESULTS: We analyzed 32,972 hospitalizations for PSC involving ERCP, with 12,891 admissions (39.1%) receiving antibiotics before ERCP (cases) and 20,081 (60.9%) serving as controls. Cases were older than controls (mean age: 64.2 ± 8.6 vs. 61.3 ± 6.1 years; P = 0.020). Compared with controls, hospitalizations with antibiotic prophylaxis had a higher male population (7,541 (58.5%) vs. 11,265 (56.1%); P < 0.001) and higher comorbidity burden (Charlson comorbidity index score of ≥2: 5,867 (45.5%) of cases vs. 8,996 (44.8%) of controls; P = 0.01). Incidence of post-ERCP septicemia was 19.1% (6,275) with 2,935 incidences (22.8%) among cases compared with 3,340 (16.6%) among controls. Antibiotic prophylaxis did not significantly improve the odds of septicemia (aOR: 0.85; 95% CI: 0.77 - 1.09; P = 0.179). Approximately 2,271 (6.9%) cases of acute cholangitis and 5,625 (17.1%) cases of acute post-ERCP pancreatitis were recorded. After adjustments for multiple variables, no significant difference was observed in the odds of cholangitis (aOR: 0.87; 95% CI: 0.98 - 1.45; P = 0.08). However, antibiotic prophylaxis was correlated with a statistically significant reduction in the odds ratio of acute post-ERCP pancreatitis (aOR: 0.61; 95% CI: 0.57 - 0.66; P < 0.001).
    CONCLUSIONS: The use of antibiotic prophylaxis in hospitalizations with PSC was correlated with a significant reduction in the odds of post-ERCP pancreatitis. Antibiotic prophylaxis did not improve the odds of post-ERCP sepsis or cholangitis. Prophylactic use of antibiotics should be individualized, considering both their anti-infective benefits and potential impact on the biochemical markers of liver disease.

    目的:确定麦卢卡蜂蜜对伤寒沙门氏菌多药耐药(MDR)和广泛耐药(XDR)临床菌株的疗效。材料与方法:使用Bactec血液培养系统处理临床分离株,通过聚合酶链反应(PCR)鉴定Vitek2和抗生素抗性基因的抗菌谱。微肉汤稀释试验评估了麦卢卡蜂蜜的抗菌活性。结果:MDR和XDR-S。伤寒对阿奇霉素敏感。这些菌株携带H58,gyrA,gyrB,blaCTX-M-15,和blaTEM-1基因.100%蜂蜜,MDR(15-23毫米)和XDR(15-24毫米)菌株的抑制区。18/50MDR和14/50XDR菌株在3.125v/v%时分别在6.25v/v%浓度下杀死。结论:麦卢卡蜂蜜可能是治疗伤寒沙门氏菌感染的替代选择。
    伤寒是由伤寒沙门氏菌引起的威胁生命的细菌感染。这些细菌通过污染的水和食物传播并引起发烧,腹痛,头痛,呕吐,腹泻主要发生在5岁以下儿童。大约有900万人感染了伤寒沙门氏菌,每年增加1,000人死亡。从澳大利亚和新西兰的麦卢卡树的花朵中收集花蜜的蜜蜂会产生一种称为麦卢卡蜂蜜的蜂蜜。这种蜂蜜以其抗菌活性而闻名,和潜在的健康益处。因此,我们的目的是确定其对伤寒沙门氏菌的抗菌活性。我们的发现表明,常用的抗生素不能杀死伤寒沙门氏菌,因为它们的DNA具有抗药性。涂了manuka蜂蜜后,这些细菌被杀死,并在琼脂平板上给出15-24mm的清晰区域。进一步的分析表明,在低浓度的麦卢卡蜂蜜中,3.1%和6.25%,大部分伤寒沙门氏菌停止生长并被杀死,分别。这项研究表明,麦卢卡蜂蜜,这是负担得起的,容易获得,在进一步分析后,可以用作治疗这些有害细菌产生的感染的治疗选择。
    Aim: To determine the efficacy of manuka honey against multidrug-resistant (MDR) and extensively drug-resistant (XDR) clinical strains of Salmonella Typhi. Materials & methods: Clinical isolates were processed using the Bactec blood culture system, identification and antibiogram by Vitek 2 and antibiotic resistance genes through polymerase chain reaction (PCR). Microbroth dilution assays evaluated the antibacterial activity of manuka honey. Results: MDR and XDR-S. Typhi was susceptible to azithromycin. These strains carried the H58, gyrA, gyrB, blaCTX-M-15 , and blaTEM-1 genes. At 100% honey, the zone of inhibition for MDR (15-23 mm) and XDR (15-24 mm) strains. 18/50 MDR and 14/50 XDR strains inhibited at 3.125 v/v% killed at 6.25 v/v% concentration respectively. Conclusion: Manuka honey could be an alternative option for treating S. Typhi infections.
    Typhoid fever is a life-threatening bacterial infection caused by the Salmonella Typhi. These bacteria are transmitted through contaminated water and food and cause fever, abdominal pain, headache, vomiting, and diarrhea mainly in children under 5. There are around 9 million people get infected with S. Typhi, with an increased death of 1,10,000 annually. Bees that collect nectar from the blossoms of the Manuka tree in Australia and New Zealand produce a type of honey known as manuka honey. This honey is famous for its antibacterial activity, and potential health benefits. Therefore, we aimed to determine its antibacterial activity against S. Typhi. Our finding shows that the commonly available antibiotics did not kill S. Typhi because their DNA was drug-resistant. After applying the manuka honey, these bacteria were killed and given a clear zone ranging from 15–24mm on the agar plate. Further analysis revealed that at low concentrations of manuka honey, 3.1% and 6.25%, most of the S. Typhi stopped growing and killed, respectively. This study suggested that manuka honey, which is affordable and readily available, could be used as a treatment option to treat infections produced by these harmful bacteria after further analysis.

    背景:脓毒症是全世界儿科患者发病和死亡的主要原因之一。脓毒症的微生物学模式各不相同,因此有必要对致病生物及其抗菌敏感性模式进行研究。埃塞俄比亚新生儿和小儿败血症的流行病学正在研究中。这项研究的目的是评估怀疑败血症的儿童中细菌病原体的负担及其抗菌药物敏感性模式。
    方法:一项基于机构的前瞻性横断面研究于2020年12月至2021年11月在冈达尔大学综合专科医院对370名疑似脓毒症的儿科(年龄-15岁)患者进行。无菌收集血液样品并接种到胰蛋白内酯大豆肉汤中进行培养。通过标准微生物学方法鉴定生长的生物,并通过临床实验室和标准研究所推荐的改良Kirby-Bauer圆盘扩散方法进行抗生素敏感性测试。使用头孢西丁纸片扩散法确认甲氧西林抗性。使用社会科学统计软件包(SPSS)版本26软件进行数据输入和分析。在95%置信区间小于0.05的p值被认为是静态显著的。
    结果:在总共370个研究对象中,其中21.6%(80/370)为培养阳性。其中,革兰阳性和革兰阴性病原菌43例(53.8%)和37例(46.3%),分别。最普遍的革兰氏阳性细菌分离物是金黄色葡萄球菌(n=24;30%)和凝固酶阴性葡萄球菌(n=7;8.8%)。在革兰氏阴性细菌分离物中,主要细菌是肺炎克雷伯菌(n=20;25%),其次是大肠杆菌(n=7;8.8%)。克林霉素,氯霉素,庆大霉素和环丙沙星是针对革兰氏阳性菌分离株最有效的抗生素,而阿米卡星,美罗培南和氯霉素对革兰氏阴性病原体有效。金黄色葡萄球菌对甲氧西林耐药率为45.8%。在76%的细菌分离物中观察到多药耐药(MDR)抗菌药物敏感性模式。
    结论:在小儿脓毒症病例中,革兰阳性菌是主要分离菌,大多数分离菌表现为MDR。金黄色葡萄球菌和肺炎克雷伯菌是常见的分离细菌。耐药性的高患病率保证了合理使用抗生素和需要定期进行抗生素敏感性监测研究。
    BACKGROUND: Sepsis is one of the major causes of morbidity and mortality among pediatric patients throughout the world. The varying microbiological pattern of sepsis warrants the need for researches on the causative organisms and their antimicrobial susceptibility pattern. The epidemiology of neonatal and pediatric sepsis in Ethiopia is under-research. The objective of this study was to evaluate the burden of bacterial pathogens and their antimicrobial susceptibility patterns among children suspected of sepsis.
    METHODS: An institutional-based prospective cross-sectional study was conducted on 370 pediatric(age birth-15 years) patients suspected of sepsis at the University of Gondar Comprehensive Specialized hospital from December 2020 to November 2021. Blood samples were collected aseptically and inoculated into Tryptone Soya Broth for culture. The organisms grown were identified by standard microbiological methods and subjected to antibiotic susceptibility testing by modified Kirby-Bauer disk diffusion method recommended by Clinical laboratory and standard institute. Methicillin resistance was confirmed using Cefoxitin disk diffusion method. Data entry and analysis were done using Statistical Package for Social Sciences (SPSS) version 26 software. A p-value less than 0.05 at 95% confidence interval was considered statically significant.
    RESULTS: Out of the total 370 study subjects, 21.6% (80/370) of them were culture positive. Of these, 43 (53.8%) and 37 (46.3%) were Gram-positive and Gram-negative bacterial pathogens, respectively. The most prevalent Gram-positive bacterial isolate was Staphylococcus aureus (n = 24; 30%) and coagulase negative staphylococci (n = 7; 8.8%). Among the Gram-negative bacterial isolates, the leading bacteria was Klebsiella pneumoniae (n = 20; 25%) followed by Escherichia coli (n = 7; 8.8%). Clindamycin, Chloramphenicol, Gentamicin and Ciprofloxacin were the most effective antibiotics against Gram-positive bacterial isolates while Amikacin, Meropenem and Chloramphenicol were effective against Gram-negative pathogens. Methicillin resistance was detected in 45.8% of Staphylococcus aureus. Multi-drug resistance (MDR) antimicrobial susceptibility pattern was observed in 76% of the bacterial isolates.
    CONCLUSIONS: Gram positive bacteria were the predominant isolates among pediatric sepsis cases and most of the bacterial isolates showed MDR. Staphylococcus aureus and Klebsiella pneumoniae were frequently isolated bacteria. The high prevalence of drug resistance warrants rational use of antibiotics and the need for regular antibiotic susceptibility surveillance studies.

    使用实验性败血症的体外模型研究了未调理和调理的金黄色葡萄球菌2879M和大肠杆菌321菌株对对接过程中内皮细胞和中性粒细胞之间相互作用的总强度的影响。我们观察到在非调理菌株的影响下,嗜中性粒细胞受体和内皮细胞之间的粘附力和功降低,并且在调理金黄色葡萄球菌的影响下,细胞之间的单个相互作用的亲和力进一步降低,这通过增加接触数量来补偿,以及与未调理细菌相比,在调理大肠杆菌的影响下粘附力的增加,仍然低于控制水平,而粘合工作达到控制水平。因此,金黄色葡萄球菌的调理作用加重了中性粒细胞和内皮细胞之间的“免疫解偶联”,而与未调理的细菌相比,大肠杆菌的调理作用降低了病理效应。
    The influence of non-opsonized and opsonized S. aureus 2879M and E. coli 321 strains on the total strength of interaction between the endothelial cell and neutrophil during the docking process was studied using in vitro model of experimental septicemia. We observed a decrease in the force and work of adhesion between receptors of neutrophils and endothelial cells under the influence of non-opsonized strains and further decrease in the affinity of single interactions between cells under the influence of opsonized S. aureus, which was compensated by an increase in the number of contacts, as well as an increase in the force of adhesion under the influence of opsonized E. coli compared to non-opsonized bacteria, which remained below the control level, while adhesion work reaches the control level. Thus, opsonization of S. aureus aggravates the \"immunological uncoupling\" between neutrophils and endothelial cells, while opsonization of E. coli reduces the pathological effect compared to non-opsonized bacteria.

    背景:新生儿败血症仍然是一个重大的医疗保健挑战,特别是在资源有限的环境中,早发性新生儿败血症(EONS)和晚发性新生儿败血症(LONS)均导致发病率和死亡率。这项研究旨在描述印度北部三级医疗机构中新生儿败血症的临床病因学特征和抗生素敏感性模式。
    方法:从2021年3月至2022年2月进行了一项横断面分析研究,包括儿科收治的疑似新生儿败血症的新生儿,通过血培养阳性证实。
    结果:共纳入96例新生儿,以男性为主(71.9%)。革兰氏阴性菌占分离株的61.6%,最常见的是非乳糖发酵罐组(38.4%),其次是凝固酶阴性葡萄球菌(CoNS)(33.4%)。非乳糖发酵罐组细菌在EONS病例中突出(44.6%),而CoNS在LONS病例中占主导地位(51.6%)。出生地,出生体重,围产期评分与EONS和LONS均显著相关。利奈唑胺对革兰氏阳性菌表现出很高的疗效,而环丙沙星和美罗培南对各种革兰阴性病原体均有效。耐甲氧西林金黄色葡萄球菌(MRSA)菌株对该研究中使用的所有抗生素均表现出耐药性,利奈唑胺除外。
    结论:这些发现强调了以当地流行病学数据为指导的量身定制的经验性治疗对于优化临床结果和减轻抗菌药物耐药性的重要性。
    BACKGROUND: Neonatal septicemia remains a significant healthcare challenge, particularly in resource-limited settings, with both early-onset neonatal septicemia (EONS) and late-onset neonatal septicemia (LONS) presentations contributing to morbidity and mortality. This study aimed to characterize the clinico-etiological profile and antibiotic susceptibility patterns of neonatal septicemia in a tertiary care setting in north India.
    METHODS: An analytical cross-sectional study was conducted from March 2021 to February 2022, encompassing neonates admitted to the Department of Pediatrics with suspected neonatal septicemia, confirmed by positive blood cultures.
    RESULTS: A total of 96 neonates were included, predominantly male (71.9%). Gram-negative bacteria constituted 61.6% of isolates, and the most common organism isolated was non-lactose fermenter group (38.4%) followed by coagulase-negative staphylococci (CoNS) (33.4%). Non-lactose fermenter group bacteria were prominent in EONS cases (44.6%), while CoNS predominated in LONS cases (51.6%). Birthplace, birth weight, and perinatal score were significantly associated with both EONS and LONS. Linezolid exhibited high efficacy against gram-positive bacteria, while ciprofloxacin and meropenem demonstrated effectiveness against various gram-negative pathogens. Methicillin-resistant Staphylococcus aureus (MRSA) strains exhibited resistance to all the antibiotics used in the study except for linezolid.
    CONCLUSIONS: These findings underscore the importance of tailored empirical therapy guided by local epidemiological data to optimize clinical outcomes and mitigate antimicrobial resistance.

    UNASSIGNED: Around twenty percent of meningitis survivors experience after-effects. However, very little research on their psychological impact has been conducted. This report details a small explorative investigation into these psychological impacts.
    UNASSIGNED: To explore the impact sequelae have on the meningitis survivors affected.
    UNASSIGNED: Thematic analysis of one-hundred individual user\'s blog posts, self-reporting one or more sequelae after a diagnosis of meningitis.
    UNASSIGNED: Blog posters\' experiences varied greatly. Common trends in experience were mapped onto three themes. \'Struggling to Adjust to the New Normal\' captures blog posters\' struggles in returning to their lives post-hospitalization. \'Navigating Possibilities for Positivity\' explores how blog posters either reported positive change due to their illness experience or felt a pressure, or inability, to do so. \'The Impact of Knowledge and Support\' overarching two sub-themes; \'Lack of Awareness Causing Further Suffering\' and \'Validation Leads to Narrative Shift\'. These sub-themes contrast differences in experience blog posters reported, with and without knowledge, of the cause of their symptoms and support in dealing with the resulting difficulties.
    UNASSIGNED: Consistent and structured after-care would benefit patients experiencing sequelae. Suggestions of a possible format this could take are put forward. In addition, self-regulatory models of illness perception help explain some variations in blog posters experiences, with possible intervention plans based on these models also suggested. However, limitations, including the comparatively small and highly selected sample, mean that further research is necessary to validate the findings and assess their validity, widespread applicability, and financial feasibility.

    肠外致病性大肠杆菌(ExPEC)菌株能够在人和动物中引起各种全身性感染。在这项研究中,我们从死于败血症的幼年(<3月龄)骆驼小牛的实质器官和大脑中分离并鉴定了30株大肠杆菌。其中6株表现出高粘膜粘性表型。基于最小抑制浓度(MIC)值,其中7株具有潜在的多重耐药性,另外两个显示粘菌素抗性。四个菌株表现出混合的病理类型,因为它们携带了大肠杆菌肠道致病型的特征性毒力基因:三株携带cnf1,编码细胞毒性坏死性因子1型,这是坏死性大肠杆菌(NTEC)的关键毒力基因,一个携带eae编码内膜蛋白,肠致病性大肠杆菌(EPEC)的关键毒力基因。对致病性岛(PAIs)的整合位点和与噬菌体相关的序列的存在的调查表明,这些菌株携带不同的可移动遗传元件阵列,这可能有助于他们的抗菌素耐药性和毒力模式。我们的工作是第一个描述来自骆驼的ExPEC菌株,并指出了这种重要的家畜的兽医学致病性和人畜共患潜力。
    Extraintestinal pathogenic Escherichia coli (ExPEC) strains are capable of causing various systemic infections in both humans and animals. In this study, we isolated and characterized 30 E. coli strains from the parenchymatic organs and brains of young (<3 months of age) camel calves which died in septicemia. Six of the strains showed hypermucoviscous phenotype. Based on minimum inhibitory concentration (MIC) values, seven of the strains were potentially multidrug resistant, with two additional showing colistin resistance. Four strains showed mixed pathotypes, as they carried characteristic virulence genes for intestinal pathotypes of E. coli: three strains carried cnf1, encoding cytotoxic necrotizing factor type 1, the key virulence gene of necrotoxigenic E. coli (NTEC), and one carried eae encoding intimin, the key virulence gene of enteropathogenic E. coli (EPEC). An investigation of the integration sites of pathogenicity islands (PAIs) and the presence of prophage-related sequences showed that the strains carry diverse arrays of mobile genetic elements, which may contribute to their antimicrobial resistance and virulence patterns. Our work is the first to describe ExPEC strains from camels, and points to their veterinary pathogenic as well as zoonotic potential in this important domestic animal.

    背景:脓毒症仍然是世界范围内住院的主要原因,死亡率,和发病率。加强对急诊科(ED)高危死亡和不良结局的疑似脓毒症患者的识别,死亡率预测因子的使用是相关的.这项研究旨在确定在监测的ED中怀疑败血症的患者中应用的快速沙发(qSOFA)和严重程度标准是否实际上是死亡率的预测因子。
    方法:我们进行了一项回顾性队列研究,研究对象是1月1日在巴西一家三级护理医院的ED怀疑脓毒症的成年患者,2019年和2020年12月31日。所有疑似脓毒症患者(18岁及以上)在qSOFA评分上得分2分或以上,或在严重程度标准评分上得分至少1分,均纳入研究。
    结果:纳入研究的患者总数为665例,样本的平均年龄为73±19岁。男女比例相似。大多数患者在入院时表现为qSOFA≥2(58.80%),356例患者(53.61%)在严重程度标准中得分1分。总死亡率为19.7%(131例),其中98例(14.74%)血培养阳性,主要显示大肠杆菌是最分离的细菌。qSOFA评分和严重程度标准均与死亡率无关,但是在qSOFA上得分任何一点被认为是重症监护病房(ICU)入院的独立因素(qSOFA=1分,p=0.02;qSOFA=2分,p=0.03,qSOFA=3分,p=0.04)。血培养阳性(RR,1.63;95%CI,1.10至2.41)和ED处血管升压药的一般管理(RR,2.14;95%CI,1.44至3.17)与30天死亡率相关。在ED(RR,2.25;CI95%,发现1.58至3.21)是总死亡率的预测因子。
    结论:尽管发现qSOFA与ICU入院之间存在关联,qSOFA或严重程度标准与死亡率无相关性.因此,有严重程度倾向的患者可以在急诊科得到更快、更有效的识别和治疗.需要进一步的研究来评估新的评分或生物标志物,以预测接受ED初始护理的脓毒症患者的死亡率。
    BACKGROUND: Sepsis remains a worldwide major cause of hospitalization, mortality, and morbidity. To enhance the identification of patients with suspected sepsis at high risk of mortality and adverse outcomes in the emergency department (ED), the use of mortality predictors is relevant. This study aims to establish whether quick sofa (qSOFA) and the severity criteria applied in patients with suspicion of sepsis in a monitored ED are in fact predictors of mortality.
    METHODS: We performed a retrospective cohort study among adult patients with suspicion of sepsis at the ED of a tertiary care hospital in Brazil between January 1st, 2019 and December 31, 2020. All adult patients (ages 18 and over) with suspected sepsis that scored two or more points on qSOFA score or at least one point on the severity criteria score were included in the study.
    RESULTS: The total of patients included in the study was 665 and the average age of the sample was 73 ± 19 years. The ratio of men to women was similar. Most patients exhibited qSOFA ≥ 2 (58.80%) and 356 patients (53.61%) scored one point in the severity criteria at admission. The overall mortality rate was 19.7% (131 patients) with 98 patients (14.74%) having positive blood cultures, mainly showing Escherichia coli as the most isolated bacteria. Neither scores of qSOFA nor the severity criteria were associated with mortality rates, but scoring any point on qSOFA was considered as an independent factor for intensive care unit (ICU) admission (qSOFA = 1 point, p = 0.02; qSOFA = 2 points, p = 0.03, and qSOFA = 3 points, p = 0.04). Positive blood cultures (RR, 1.63;95% CI, 1.10 to 2.41) and general administration of vasopressors at the ED (RR, 2.14;95% CI, 1.44 to 3.17) were associated with 30-day mortality. The administration of vasopressors at the ED (RR, 2.25; CI 95%, 1.58 to 3.21) was found to be a predictor of overall mortality.
    CONCLUSIONS: Even though an association was found between qSOFA and ICU admission, there was no association of qSOFA or the severity criteria with mortality. Therefore, patients with a tendency toward greater severity could be identified and treated more quickly and effectively in the emergency department. Further studies are necessary to assess novel scores or biomarkers to predict mortality in sepsis patients admitted to the ED\'s initial care.

    虽然败血症引起的死亡率仍然是一个未解决的问题,研究显示,单克隆抗体和多克隆抗体在脓毒症患者中的有效性结果相互矛盾.出于这个原因,本研究提供了截至2024年3月的回顾临床随机试验研究的最新资料.这项研究的主要目的是确定单克隆和多克隆抗体对脓毒症患者死亡率和住院率的影响。搜索Scopus,WebofScience,EMBASE,进行了PubMed和Cochrane,并纳入了在感染性休克或细菌性败血症患者中进行的随机对照试验。两名审查人员根据已经定义的标准评估了所有搜索试验的资格,并随后进行了数据收集和分析。目前的研究表明,单克隆和多克隆抗体是一种安全的策略,具有轻度至中度的不良反应。然而,大多数研究表明,组间和组间比较没有显著变化(p>0.05),需要进一步研究,结果显示存活率提高,无呼吸机和ICU的天数,解决器官功能障碍,介导炎症相关细胞因子。
    While mortality caused by sepsis remains an unsolved problem, studies showed conflicting results about effectiveness of monoclonal and polyclonal antibodies in patients suffering sepsis. For this reason, this current study provides an update of review clinical randomized trial studies until March 2024. The main object of this study is to determine effects of monoclonal and polyclonal antibodies on mortality rate and hospitalization of patients suffering sepsis. Search of Scopus, Web of science, EMBASE, PubMed and Cochrane were performed and randomized controlled trials which conducted in patients with septic shock or bacterial sepsis were included. Two reviewers assessed all searched trials for eligibility according to already defined criteria and did data collection and analyses afterwards. Present study showed monoclonal and polyclonal antibodies are a safe strategy with mild-to-moderate adverse effects. However, most studies indicate no significant change among inter-and intra-group comparison (p > 0.05) and further studies are needed, results showed an increase in survival rate, ventilator-and ICU-free days, resolve organ dysfunction, mediating inflammation related cytokines.

    目的:本研究旨在开发一种多重PCR检测方法,用于同时检测败血症的主要革兰氏阴性病因并评估其性能。
    方法:开发了针对11种细菌菌株的多重PCR(mPCR)测定法。使用已知的临床分离株和标准菌株确认物种特异性引物。对每个引物针对其目标细菌基因进行梯度PCR以确定其最佳扩增条件。通过将细菌DNA浓度调节至100ng/μL来评估两种测定的最小可检测DNA浓度,用无DNA酶的水将其连续稀释至10μg/μL。mPCR测定的诊断准确性是通过对60个临床血液样品进行测定来建立的。
    结果:开发了两种mPCR测定法。建立了55°C的最佳引物退火温度,并将其用于最终的扩增条件。化验检测到所有目标细菌,具有100pg的最小可检测DNA浓度。未从全血直接检测到病原体,但在孵育4小时和8小时后,在培养液中检测到41%(5/12)和100%(12/12)的细菌,分别。该测定还鉴定了沙门氏菌。与培养物相比,肺炎克雷伯菌共感染和额外病原体(1个大肠杆菌和2个肺炎克雷伯菌)。mPCR的敏感性和特异性分别为100.0%(71.7-100.0)和98.0%(90.7-99.0),分别。ROC曲线下面积为1.00(1.00-1.00)。
    结论:mPCR检测与传统的血培养方法一样,显示出作为败血症诊断的快速工具的巨大潜力。值得注意的是,它能够识别更多的分离株,检测共感染,并以高灵敏度有效检测低细菌DNA负荷,提示其在提高败血症诊断效率方面的价值。
    OBJECTIVE: This study aimed to develop a multiplex PCR assay for simultaneous detection of major Gram-negative etiologies of septicemia and evaluate its performance.
    METHODS: Multiplex PCR (mPCR) assays were developed targeting 11 bacterial strains. Species-specific primers were confirmed using known clinical isolates and standard strains. Gradient PCR was performed on each primer against its target bacterial gene to determine its optimal amplification condition. The minimum detectable DNA concentration of the two assays was evaluated by adjusting bacterial DNA concentration to 100 ng/μL and, tenfold serially diluting it up to 10 pg/μL with DNAse-free water. The diagnostic accuracy of mPCR assays was established by subjecting the assays to 60 clinical blood samples.
    RESULTS: Two mPCR assays were developed. Optimal primer annealing temperature of 55 °C was established and utilized in the final amplification conditions. The assays detected all targeted bacteria, with a 100 pg minimum detectable DNA concentration. Pathogens were not detected directly from whole blood, but after 4 h and 8 h of incubation, 41% (5/12) and 100% (12/12) of the bacteria were detected in culture fluids, respectively. The assays also identified Salmonella spp. and Klebsiella pneumoniae co-infections and extra pathogens (1 E. coli and 2 K. pneumoniae) compared with culture. The sensitivity and specificity of the mPCR were 100.0% (71.7-100.0) and 98.0% (90.7-99.0), respectively. The area under the ROC curve was 1.00 (1.00-1.00).
    CONCLUSIONS: The mPCR assays demonstrated substantial potential as a rapid tool for septicemia diagnosis alongside the traditional blood culture method. Notably, it was able to identify additional isolates, detect co-infections, and efficiently detect low bacterial DNA loads with high sensitivity, implying its value in enhancing efficiency of diagnosis of septicemia.
