    这项研究利用动脉自旋标记磁共振成像(ASL-MRI)来探索与注意缺陷多动障碍(ADHD)相关的大脑活动的发育轨迹。从157名ADHD儿童和109名对照组儿童中获得了脉冲动脉自旋标记(ASL)数据。所有年龄6-12岁。参与者被分为6-7岁,8-9岁和10-12岁年龄组,然后在每个年龄组之间进行比较,以进行脑血流量(CBF)的ASL分析。总的来说,ADHD组左侧颞上回和右侧额中回的CBF明显低于对照组。进一步分析显示:(1)6-7岁的ADHD组(N=70)与年龄匹配的对照组(N=33)之间的比较差异无统计学意义。(2)然而,与8-9岁的对照组相比(N=39),相同年龄的ADHD组(N=53)在左侧中央后回和左侧额中回区域显示出明显较低的CBF。(3)进一步,与年龄匹配的对照组(N=37)相比,年龄在10~12岁的ADHD组(N=34)的左侧枕上区CBF显著降低.这些年龄特异性差异表明在6-7岁后的大脑发育过程中ADHD相关领域的变化。
    This study utilized arterial spin labeling-magnetic resonance imaging (ASL-MRI) to explore the developmental trajectory of brain activity associated with attention deficit hyperactivity disorder (ADHD). Pulsed arterial spin labeling (ASL) data were acquired from 157 children with ADHD and 109 children in a control group, all aged 6-12 years old. Participants were categorized into the age groups of 6-7, 8-9, and 10-12, after which comparisons were performed between each age group for ASL analysis of cerebral blood flow (CBF). In total, the ADHD group exhibited significantly lower CBF in the left superior temporal gyrus and right middle frontal gyrus regions than the control group. Further analysis revealed: (1) The comparison between the ADHD group (N = 70) aged 6-7 and the age-matched control group (N = 33) showed no statistically significant difference between. (2) However, compared with the control group aged 8-9 (N = 39), the ADHD group of the same age (N = 53) showed significantly lower CBF in the left postcentral gyrus and left middle frontal gyrus regions. (3) Further, the ADHD group aged 10-12 (N = 34) demonstrated significantly lower CBF in the left superior occipital region than the age-matched control group (N = 37). These age-specific differences suggest variations in ADHD-related domains during brain development post age 6-7.

    背景:自杀是一个重要的公共卫生问题。已经开发了许多风险预测工具来估计个人的自杀风险。风险预测模型可以超越个体风险评估,风险预测模型的一个重要应用是人口健康规划。自杀是个体风险和保护因素相互作用的结果,卫生保健系统,和社区层面。因此,政策和决策者可以在预防自杀方面发挥重要作用。然而,针对人群自杀风险的预测模型很少。
    目的:本研究旨在使用卫生行政数据开发和验证人群自杀风险的预测模型,考虑到个人-,卫生系统-,和社区层面的预测因子。
    方法:我们使用病例对照研究设计来开发针对自杀的性别特异性风险预测模型,使用魁北克的卫生行政数据,加拿大。训练数据包括2002年1月1日至2010年12月31日发生的所有自杀病例(n=8899)。对照组是在2002年1月1日至2010年12月31日之间每年的1%的生活个体随机抽样(n=645,590)。采用Logistic回归建立了基于个体的预测模型,医疗保健系统-,和社区层面的预测因子。将开发的模型转换为综合估计模型,将个人水平的预测因子与社区水平的预测因子相协调。综合估计模型直接应用于2011年1月1日至2019年12月31日的验证数据。我们用四个指标评估了综合估计模型的性能:预测和观察到的自杀比例之间的一致性,平均平均误差,均方根误差,以及正确识别的高风险区域的比例。
    结果:基于个体数据的性别特异性模型具有良好的辨别(男性模型:C=0.79;女性模型:C=0.85)和校准(男性模型的Brier得分0.01;女性模型的Brier得分0.005)。通过在验证数据中应用基于回归的合成模型,综合风险估计值和观察到的自杀风险之间的绝对差异为0%~0.001%.均方根误差小于0.2。男性的综合估计模型在8年内正确预测了5个高危地区中的4个,女性模型在5年内正确预测了5个高危地区中的4个。
    结论:使用链接的卫生管理数据库,这项研究证明了建立人群自杀风险预测模型的可行性和有效性,融入个人-,卫生系统-,和社区层面的变量。基于常规收集的卫生管理数据建立的综合估计模型可以准确预测人群自杀风险。可以通过及时获取人口一级的其他关键信息来加强这一努力。
    BACKGROUND: Suicide is a significant public health issue. Many risk prediction tools have been developed to estimate an individual\'s risk of suicide. Risk prediction models can go beyond individual risk assessment; one important application of risk prediction models is population health planning. Suicide is a result of the interaction among the risk and protective factors at the individual, health care system, and community levels. Thus, policy and decision makers can play an important role in suicide prevention. However, few prediction models for the population risk of suicide have been developed.
    OBJECTIVE: This study aims to develop and validate prediction models for the population risk of suicide using health administrative data, considering individual-, health system-, and community-level predictors.
    METHODS: We used a case-control study design to develop sex-specific risk prediction models for suicide, using the health administrative data in Quebec, Canada. The training data included all suicide cases (n=8899) that occurred from January 1, 2002, to December 31, 2010. The control group was a 1% random sample of living individuals in each year between January 1, 2002, and December 31, 2010 (n=645,590). Logistic regression was used to develop the prediction models based on individual-, health care system-, and community-level predictors. The developed model was converted into synthetic estimation models, which concerted the individual-level predictors into community-level predictors. The synthetic estimation models were directly applied to the validation data from January 1, 2011, to December 31, 2019. We assessed the performance of the synthetic estimation models with four indicators: the agreement between predicted and observed proportions of suicide, mean average error, root mean square error, and the proportion of correctly identified high-risk regions.
    RESULTS: The sex-specific models based on individual data had good discrimination (male model: C=0.79; female model: C=0.85) and calibration (Brier score for male model 0.01; Brier score for female model 0.005). With the regression-based synthetic models applied in the validation data, the absolute differences between the synthetic risk estimates and observed suicide risk ranged from 0% to 0.001%. The root mean square errors were under 0.2. The synthetic estimation model for males correctly predicted 4 of 5 high-risk regions in 8 years, and the model for females correctly predicted 4 of 5 high-risk regions in 5 years.
    CONCLUSIONS: Using linked health administrative databases, this study demonstrated the feasibility and the validity of developing prediction models for the population risk of suicide, incorporating individual-, health system-, and community-level variables. Synthetic estimation models built on routinely collected health administrative data can accurately predict the population risk of suicide. This effort can be enhanced by timely access to other critical information at the population level.

    我们的目的是评估血清Raftlin水平作为诊断和监测轴性脊柱关节炎(axSpA)和银屑病关节炎(PsA)患者疾病活动的生物标志物。这项试验包括40名axSpA患者,40名PsA患者,40名健康参与者作为对照组。通过axSpA患者的强直性脊柱炎疾病活动评分和PsA患者的银屑病关节炎疾病活动指数评估疾病活动。加拿大脊柱关节炎研究协会指数,健康评估问卷-残疾指数,和数字评定量表用于评估附着点炎的严重程度,残疾,以及所有患者的疼痛状况。使用ELISA方法测定血清Raftlin水平。3组性别差异无统计学意义。年龄,体重,高度,BMI,教育状况,锻炼习惯。axSpA组的Raftlin水平高于PsA和对照组,和Raftlin水平在预测axSpA可能性方面具有统计学意义。我们发现PsA组和对照组之间没有统计学上的显着差异。我们发现axSpA和PsA组中HLA-B27阳性与HLA-B27阴性患者的Raftlin水平无统计学差异。我们的结果也没有检测到Raftlin水平与强直性脊柱炎疾病活动评分的任何相关性,C反应蛋白,红细胞沉降率,健康评估问卷-残疾指数,数字评级量表,和加拿大脊柱关节炎研究协会在axSpA患者中的指数。受试者工作特征分析确定Raftlin水平≥6.31ng/mL区分axSpA与正常个体的灵敏度为92.5%,59%的特异性,曲线下面积为0.738。我们的结果表明,尽管axSpA患者的血清Raftlin水平升高,Raftlin不能用作axSpA的单独诊断标记。此外,没有发现它与疾病活动的监测有关,疼痛的程度,残疾,或附着炎的严重程度。这项研究在www上进行了前瞻性注册。clinicaltrials.gov(ID:NCT05771389)。
    Our aim is to evaluate serum Raftlin levels as a biomarker for diagnosing and monitoring disease activity in patients with axial spondyloarthritis (axSpA) and Psoriatic arthritis (PsA). This trial included 40 axSpA patients, 40 PsA patients, and 40 healthy participants as the control group. Disease activity was assessed with Ankylosing Spondylitis Disease Activity Score for axSpA patients and The Disease Activity Index for Psoriatic Arthritis for PsA patients. The Spondyloarthritis Research Consortium of Canada index, health assessment questionnaire-disability index, and numeric rating scale were used to evaluate the enthesitis severity, disability, and pain status of all patients. Serum Raftlin levels were determined using the ELISA method. The 3 groups had no statistical differences regarding gender, age, weight, height, BMI, educational status, and exercise habits. The axSpA group had higher Raftlin levels than the PsA and control groups, and Raftlin levels were statistically significant in predicting the likelihood of axSpA. We found no statistically significant differences between the PsA and control groups. We found no statistically significant difference in Raftlin levels in HLA-B27 positive versus HLA-B27 negative patients in both axSpA and PsA groups. Our results also did not detect any correlation of Raftlin levels with Ankylosing Spondylitis Disease Activity Score, C-reactive protein, erythrocyte sedimentation rate, health assessment questionnaire-disability index, numeric rating scale, and Spondyloarthritis Research Consortium of Canada index in axSpA patients. Receiver operating characteristic analysis determined that Raftlin level ≥ 6.31 ng/mL discriminates axSpA from normal individuals with 92.5% sensitivity, 59% specificity, and an area under the curve of 0.738. Our results demonstrate that although serum Raftlin levels are elevated in axSpA patients, Raftlin cannot be used as an alone diagnostic marker for axSpA. Furthermore, it was not found to be related to the monitoring of disease activity, the level of pain, disability, or severity of enthesitis. This study is prospectively registered at www.clinicaltrials.gov (ID: NCT05771389).

    Introducción: La exposición nutricional se considera la principal exposición ambiental que contribuye a la formación de cálculos biliares. El objetivo de este trabajo fue determinar el patrón de consumo alimentario de casos y controles de EC y estimar el riesgo de desarrollar la enfermedad según los distintos patrones constituidos. Métodos: Se llevó a cabo un estudio analítico retrospectivo transversal de casos y controles, anidado a un estudio de prevalencia realizado en Rosario. Todos los participantes fueron entrevistados personalmente. El consumo de alimentos se consignó a través de un cuestionario semi-cuantitativo de frecuencia de consumo. Para determinar patrones de consumo alimentario se realizó un análisis de componentes principales, y análisis de regresión logística múltiple para evaluar riesgos. Resultados: La muestra quedó conformada por 51 casos y 69 controles. Se determinaron dos componentes que permitían diferenciar los casos de los controles, a través de las cuales se establecieron 2 patrones de consumo. Los casos se caracterizaron por un consumo determinado por el Patrón Poco saludable (altas ingestas de grasas animales, azúcar, cereales, granos, fiambres y embutidos) y los controles por el consumo del patrón Saludable (altas ingestas de pollo sin piel, frutas secas, carne vacuna magra, frutas, lácteos enteros). El patrón Poco saludable, aumentó el riesgo de desarrollar EC mientras que el patrón Saludable, se comportó como protector. Conclusión principal: Los patrones constituidos diferencian los casos de los controles, y la ingesta propia de los casos se correlaciona con un perfil de consumo que caracteriza a las culturas occidentales modernas y urbanas.

    背景:伯基特淋巴瘤(BL)是一种与恶性疟原虫和EB病毒相关的侵袭性非霍奇金淋巴瘤,两者都会影响代谢途径。BL的代谢组学模式未知。
    方法:我们使用液相色谱-串联质谱法测定了来自乌干达东非儿童和未成年人Burkitt淋巴瘤流行病学研究的25名男性儿童(6-11岁)和25名无癌区域和年龄频率匹配的男性对照的化疗前血浆样本中的627种代谢物。无条件,使用年龄调整的逻辑回归分析来估计与对数代谢物浓度增加1个标准偏差的BL关联的比值比(ORs)及其95%置信区间(CIs),使用错误发现率(FDR)阈值和Bonferroni校正来调整多重比较。
    结果:与对照组相比,BL病例中42种代谢物浓度的水平不同(FDR<0.001),包括三酰甘油酯(18:0_38:6),α-氨基丁酸(AABA),神经酰胺(d18:1/20:0),磷脂酰胆碱C40:6和磷脂酰胆碱C38:6作为与BL相关的顶部信号(OR=6.9至14.7,P<2.4×10-4)。使用逐步逻辑回归选择的两种代谢物(三酰甘油酯(18:0_38:6)和AABA)将BL病例与对照组区分开,曲线下面积为0.97(95%CI:0.94,1.00)。
    结论:我们的发现需要进一步检查血浆代谢物作为BL风险/诊断的潜在生物标志物。
    BACKGROUND: Burkitt lymphoma (BL) is an aggressive non-Hodgkin lymphoma associated with Plasmodium falciparum and Epstein-Barr virus, both of which affect metabolic pathways. The metabolomic patterns of BL is unknown.
    METHODS: We measured 627 metabolites in pre-chemotherapy treatment plasma samples from 25 male children (6-11 years) with BL and 25 cancer-free area- and age-frequency-matched male controls from the Epidemiology of Burkitt Lymphoma in East African Children and Minors study in Uganda using liquid chromatography-tandem mass spectrometry. Unconditional, age-adjusted logistic regression analysis was used to estimate odds ratios (ORs) and their 95% confidence intervals (CIs) for the BL association with 1-standard deviation increase in the log-metabolite concentration, adjusting for multiple comparisons using false discovery rate (FDR) thresholds and Bonferroni correction.
    RESULTS: Compared to controls, levels for 42 metabolite concentrations differed in BL cases (FDR < 0.001), including triacylglyceride (18:0_38:6), alpha-aminobutyric acid (AABA), ceramide (d18:1/20:0), phosphatidylcholine ae C40:6 and phosphatidylcholine C38:6 as the top signals associated with BL (ORs = 6.9 to 14.7, P < 2.4✕10- 4). Two metabolites (triacylglyceride (18:0_38:6) and AABA) selected using stepwise logistic regression discriminated BL cases from controls with an area under the curve of 0.97 (95% CI: 0.94, 1.00).
    CONCLUSIONS: Our findings warrant further examination of plasma metabolites as potential biomarkers for BL risk/diagnosis.

    甘油三酯-葡萄糖(TyG)指数是心血管疾病中动脉粥样硬化的标志。TyG指数被认为对血管损害的评估具有临床意义。在这项研究中,我们旨在证明TyG指数与视网膜静脉阻塞(RVO)之间的联系。
    这项病例对照观察性研究涉及492名40-90岁的参与者,他们在我院眼科门诊就诊。使用以下公式计算TyG指数:ln(空腹TG[mg/dL]X空腹血浆葡萄糖[mg/dL]/2)。
    RVO组包括387名患者(181名女性和206名男性),对照组包括115名患者(61名女性和54名男性)。RVO组患者平均年龄为62.9±11.1岁,对照组为56.7±8.7岁。RVO组的TyG指数(8.9±0.7)高于对照组(8.8±0.6)。这种差异具有统计学意义(p=0.04)。通过多变量逻辑回归分析,根据年龄和性别评估相关性具有统计学意义(比值比:1.45,置信区间:1.03-2.02,p=0.03)。
    TyG指数是一种新颖的致动脉粥样硬化指数,源自常规血液测试,可用于通过简单的计算确定高危个体的RVO风险。因此,TyG指数可以作为一个可靠的指南,帮助确定处于RVO的高危个体并开始早期干预.
    UNASSIGNED: The triglyceride-glucose (TyG) index is a sign of atherosclerosis in cardiovascular diseases. The TyG index is thought to have clinical significance for the assessment of vascular damage. In this study we aimed to demonstrate the connection between the TyG index and retinal vein occlusion (RVO).
    UNASSIGNED: This case-control observational study involved 492 participants aged 40-90, admitted to the ophthalmology outpatient clinic of our hospital. TyG index was calculated using the formula: ln(fasting TG [mg/dL] × fasting plasma glucose [mg/dL]/2).
    UNASSIGNED: The RVO group included 387 patients (181 women and 206 men) and the control group included 115 patients (61 women and 54 men). The average patient age was 62.9±11.1 years in the RVO group and 56.7±8.7 years in the control group. The TyG index was higher in the RVO group (8.9±0.7) than in the control group (8.8±0.6). This difference was statistically significant (p=0.04). The correlation was statistically significant when evaluated according to age and sex by multivariate logistic regression analysis (odds ratio: 1.45, confidence interval: 1.03- 2.02, p=0.03).
    UNASSIGNED: The TyG index is a novel atherogenicity index that is derived from routine blood tests and can be used to determine the risk of RVO in at-risk individuals with a simple calculation. Therefore, the TyG index could help as a reliable guide to identify individuals at RVO with high risk and initiate early intervention.

    背景:持续的高尿酸血症可导致尿酸单钠(MSU)晶体的产生和沉积。这会引发痛风性关节炎(GA),进而诱发炎症。含有Nod样受体pyrin结构域3(NLRP3)炎性体的激活在GA的发生和发展中起关键作用。关于NLRP3炎性体,自噬可能对GA具有双重作用。因此,本研究旨在更深入地了解自噬与NLRP3炎性体激活之间的相互作用,这对于开发更有效的GA治疗方法至关重要.
    方法:首先从GA患者和健康对照中分离外周血单核细胞(PBMC),并进行大量RNA测序分析。在THP-1单核细胞中进行双特异性磷酸酶1(DUSP1)的过表达和敲低,以研究其在免疫反应和线粒体损伤中的作用。采用荧光素酶法和Westernblot法研究自噬与NLRP3炎性体活化的相互作用。
    结果:BulkRNA测序分析显示,与健康对照相比,GA患者的PBMC中DUSP1表达显著上调。随后通过逆转录定量聚合酶链反应(RT-qPCR)验证该结果。人THP-1单核细胞中的DUSP1表达也显示在MSU处理后增加。DUSP1表达下调可增加MSU治疗后炎症因子的分泌,而DUSP1的过表达降低了分泌水平。脂多糖(LPS)与三磷酸腺苷(ATP)结合导致线粒体损伤,通过过度表达DUSP1来拯救。DUSP1过表达进一步增加了MSU治疗后的自噬水平,而DUSP1的下调降低了自噬。用自噬抑制剂3-甲基腺嘌呤(3-MA)治疗可恢复DUSP1过表达组的炎性细胞因子分泌水平。MSU在体内引起明显的病理性踝关节肿胀。然而,DUSP1过表达显著减轻了这种表型,伴随着关节组织中炎性细胞因子分泌水平的显著下调。
    结论:这项研究揭示了DUSP1在促进自噬以减轻MSU诱导的GA免疫反应中的新功能和机制。这一发现表明了更有效的GA治疗的潜在诊断生物标志物和抗炎靶标。
    BACKGROUND: Persistent hyperuricemia can lead to the generation and deposition of monosodium urate (MSU) crystals. This can trigger gouty arthritis (GA), which in turn induces inflammation. Activation of the Nod-like receptor pyrin domain containing 3 (NLRP3) inflammasome plays a critical role in the onset and progression of GA. Autophagy may have a dual effect on GA with regard to the NLRP3 inflammasome. Therefore, the present study aimed to gain a deeper comprehension of the interaction between autophagy and NLRP3 inflammasome activation is imperative for developing more efficacious treatments for GA.
    METHODS: Peripheral blood monocytes (PBMCs) were first isolated from GA patients and healthy controls and underwent bulk RNA sequencing analysis. Overexpression and knockdown of dual specificity phosphatase 1 (DUSP1) was performed in THP-1 monocytes to investigate its role in the immune response and mitochondrial damage. The luciferase assay and Western blot analysis were used to study the interaction between autophagy and NLRP3 inflammasome activation.
    RESULTS: Bulk RNA sequencing analysis showed significant upregulation of DUSP1 expression in PBMCs from GA patients compared to healthy controls. This result was subsequently verified by reverse transcription quantitative polymerase chain reaction (RT-qPCR). DUSP1 expression in human THP-1 monocytes was also shown to increase after MSU treatment. Downregulation of DUSP1 expression increased the secretion of inflammatory cytokines after MSU treatment, whereas the overexpression of DUSP1 decreased the secretion levels. Lipopolysaccharides (LPS) combined with adenosine-triphosphate (ATP) led to mitochondrial damage, which was rescued by overexpressing DUSP1. DUSP1 overexpression further increased the level of autophagy following MSU treatment, whereas downregulation of DUSP1 decreased autophagy. Treatment with the autophagy inhibitor 3-Methyladenine (3-MA) restored inflammatory cytokine secretion levels in the DUSP1 overexpression group. MSU caused pronounced pathological ankle swelling in vivo. However, DUSP1 overexpression significantly mitigated this phenotype, accompanied by significant downregulation of inflammatory cytokine secretion levels in the joint tissues.
    CONCLUSIONS: This study revealed a novel function and mechanism for DUSP1 in promoting autophagy to mitigate the MSU-induced immune response in GA. This finding suggests potential diagnostic biomarkers and anti-inflammatory targets for more effective GA therapy.

    2022年,匈牙利成人重症监护病房(ICU)爆发了由粘质沙雷氏菌引起的严重血流感染。八个案例,其中5人死亡,被检测到。最初的控制措施无法阻止疫情爆发。我们进行了匹配的病例对照研究。在单变量分析中,这些病例更有可能位于ICU的一个水槽周围,并且比对照组有更多的医疗程序和药物,然而,多变量分析尚无定论.通过全基因组测序,从病例的血培养物中分离出的细菌与ICU环境密切相关,并且对ICU中使用的季铵化合物表面消毒剂具有抗性或耐受性。因此,尽管有定期的清洁和消毒,但美国粘质抗生素还是能够在环境中生存。医院用另一种消毒剂代替了消毒剂,加强了清洁协议,并加强了医护人员的手部卫生依从性。一起,这些控制措施已被证明有效地防止了新病例。我们的研究结果突出了多学科暴发调查的重要性,包括环境采样,分子分型和消毒剂抗性测试。
    In 2022, an outbreak with severe bloodstream infections caused by Serratia marcescens occurred in an adult intensive care unit (ICU) in Hungary. Eight cases, five of whom died, were detected. Initial control measures could not stop the outbreak. We conducted a matched case-control study. In univariable analysis, the cases were more likely to be located around one sink in the ICU and had more medical procedures and medications than the controls, however, the multivariable analysis was not conclusive. Isolates from blood cultures of the cases and the ICU environment were closely related by whole genome sequencing and resistant or tolerant against the quaternary ammonium compound surface disinfectant used in the ICU. Thus, S. marcescens was able to survive in the environment despite regular cleaning and disinfection. The hospital replaced the disinfectant with another one, tightened the cleaning protocol and strengthened hand hygiene compliance among the healthcare workers. Together, these control measures have proved effective to prevent new cases. Our results highlight the importance of multidisciplinary outbreak investigations, including environmental sampling, molecular typing and testing for disinfectant resistance.

    背景:冠状病毒病19(COVID-19),一种由称为严重急性呼吸道综合症冠状病毒2(SARS-COV-2)的病毒引起的传染病,于2019年在中国发现,并导致几种轻度至中度呼吸系统疾病。这项研究旨在通过研究依诺肝素的作用并评估IL-10作为疾病活动标志物的潜力,揭示伊拉克COVID-19患者与健康对照组相比血清白介素10(IL-10)和其他参数的变化。
    方法:这是一项病例对照研究,包括180个样本:2022年11月至2023年4月20日90例COVID-19住院患者(40例患者从未使用过依诺肝素,而50例患者服用了依诺肝素)和90例健康,年龄和性别匹配的控制。其中女性患者44例,男性患者46例。患者和对照组的平均年龄为53.8岁。50.8年,分别。夹心酶联免疫吸附试验(ELISA)方法测定IL-10水平,而其他参数使用比色法进行评估。
    结果:研究结果表明,患者和健康对照组之间的IL-10,D-二聚体,和C反应蛋白(CRP)水平,以及肝和肾功能。这些发现阐明了依诺肝素患者与非依诺肝素患者在IL-10、D-二聚体、和CRP水平。然而,肝肾功能无明显改变.Spearman秩相关检验探讨血清IL-10与CRP的关系。
    结论:结果显示IL-10和CRP之间有很强的正相关关系。其他分析参数之间没有显着差异;因此,患者的IL-10、D-二聚体、和一些其他参数比健康控制。此外,IL-10可用作疾病活动的标志物。依诺肝素可能有助于控制患者的IL-10和D-二聚体浓度,因为依诺肝素治疗的患者IL-10水平降低。
    BACKGROUND: Coronavirus disease 19 (COVID-19), an infectious disease resulting from a virus known as severe acute respiratory syndrome coronavirus 2 (SARS-COV-2), was discovered in China in 2019 and causes several mild to moderate respiratory conditions. This study aimed to reveal the changes in serum interleukin-10 (IL-10) and other parameters in Iraqi COVID-19 patients compared with healthy controls by studying the effects of enoxaparin and evaluating the potential of IL-10 as a disease activity marker.
    METHODS: This was a case-control study that included 180 samples: 90 patients hospitalized with COVID-19 from November 2022 to 20 April 2023 (40 patients had never used enoxaparin, whereas 50 patients had taken enoxaparin) and 90 healthy, age- and sex-matched control. There were 44 female patients and 46 male patients. The mean age of the patients and controls was 53.8 years vs. 50.8 years, respectively. The sandwich enzyme-linked immunosorbent assay (ELISA) method was used to measure IL-10 levels, while other parameters were assessed using the colorimetric method.
    RESULTS: The results of the study indicated highly significant changes between the patients and healthy controls in IL-10, D-dimer, and C-reactive protein (CRP) levels, as well as liver and renal functions. These findings elucidated a significant change between enoxaparin patients and non-enoxaparin patients in IL-10, D-dimer, and CRP levels. However, the liver and renal functions were not significantly altered. The Spearman\'s rank correlation test investigated the relationship between serum IL-10 and CRP.
    CONCLUSIONS: The results displayed a strong positive relationship between IL-10 and CRP. There were no significant differences between the other analyzed parameters; consequently, the patients had higher concentrations of IL-10, D-dimer, and some other parameters than the healthy controls. Additionally, IL-10 may be used as a marker of disease activity. Enoxaparin will likely help control IL-10 and D-dimer concentrations in patients since IL-10 levels decreased in patients treated with enoxaparin.
