Aim

IL32 is a pleiotropic intracellular cytokine with an emergent role in tuberculosis. The different isoforms of IL32: α, β, γ and δ have varying pro and anti-inflammatory potentials. We studied the role of genetic variants of IL32 and its isoforms in susceptibility to tuberculosis using a case-household contact association study.

Methodology

Using a targeted sequencing approach, IL32 (+1kb) gene was sequenced in 64 pairs of culture positive TB cases and their culture negative household contacts. Subsequently the identified variants were validated in an independent cohort of cases and household contacts using TaqMan genotyping assay. Regulatory role of the associated variants was assessed using GTExPortal, RegulomeDB score, HaploReg and ENCODE histone ChIP-seq data. Expression of IL32 and its isoforms was evaluated by RT-PCR in PBMC from unexposed healthy controls (N = 25) with different genotype background and stimulated with TB antigens ESAT6 and CFP10. ∼ 200 bp around the associated variant was cloned into pGL3 promoter vector to assess enhancer activity by dual luciferase assay in cell lines.

Results

Intronic variant rs9927163(G/T) was found associated with pulmonary TB, T being the risk allele (OR = 2.3(1.40–3.83, p = 0.03)), while G is the protective allele. This finding was validated in independent set of TB cases and household contacts (p = 0.0435). rs9927163 is an eQTL for the genes IL32 (p = 4.1e-10) and BICDL2 (p = 2.1e-7) in whole blood and interrupts an AP-1 binding site. ENCODE histone ChIP-seq data shows rs9927163 residing within T cell specific H3K4me3 peak. The G allele is associated with greater enhancer activity in a T cell line (2.12 fold, p = 0.0059). The TT genotype showed greater normalized expression of IL32δ, a less proinflammatory isoform compared to the GT and GG genotypes together following ESAT6 (p = 0.02288) and CFP10 (p = 0.04595) treatment. This indicates that greater expression of a potentially less protective IL32 isoform within individuals with the TT genotype might be a risk factor for developing TB.
目的:IL32 是一种多效应细胞内细胞因子,在结核病中发挥着重要作用。IL32 的不同异构体:α、β、γ 和 δ 具有不同的促炎和抗炎潜能。我们采用病例-家庭接触关联研究的方法,研究了 IL32 及其同工型的遗传变异在结核病易感性中的作用:方法:采用靶向测序方法,对 64 对培养呈阳性的肺结核病例及其培养呈阴性的家庭接触者的 IL32(+1kb)基因进行测序。随后,使用 TaqMan 基因分型检测法在独立的病例和家庭接触者队列中验证了所发现的变异。利用 GTExPortal、RegulomeDB score、HaploReg 和 ENCODE 组蛋白 ChIP-seq 数据评估了相关变异的调控作用。通过RT-PCR方法评估了未暴露的健康对照组(N = 25)中IL32及其同工酶的表达,这些对照组具有不同的基因型背景,并接受了结核抗原ESAT6和CFP10的刺激:结果:发现基因内变异 rs9927163(G/T) 与肺结核有关,T 是风险等位基因(OR = 2.3(1.40-3.83, p = 0.03)),而 G 是保护性等位基因。rs9927163是全血中IL32(p = 4.1e-10)和BICDL2(p = 2.1e-7)基因的eQTL,它中断了一个AP-1结合位点。ENCODE 组蛋白 ChIP-seq 数据显示,rs9927163 位于 T 细胞特异性 H3K4me3 峰。G 等位基因与 T 细胞系中更强的增强子活性有关(2.12 倍,p = 0.0059)。在 ESAT6(p = 0.02288)和 CFP10(p = 0.04595)处理后,TT 基因型与 GT 和 GG 基因型相比,IL32δ(一种促炎性较低的同工酶)的正常化表达更高。这表明,在 TT 基因型的个体中,保护性较弱的 IL32 同工型的表达量更大,这可能是罹患肺结核的一个风险因素。

Background

Cytokines are potent molecules of the immune response. They act at the site of inflammation and circulate in the bloodstream. However, there are few studies on encephalitis and circulating inflammatory proteins.

Methods

In this study, Mendelian randomization (MR) was used to explore the potential causal effect of 91 circulating inflammatory proteins on 3 different types of encephalitis. Causal effects were examined using Steiger, MR-Egger, weighted median, and inverse variance weighting (IVW) methods. IVW methods were primarily used for results interpretation. In addition, sensitivity analyses were performed, including assessment of heterogeneity, horizontal pleiotropy, and Leave-one-out techniques.

Results

We subjected 91 circulating inflammatory proteins to MR analysis of causality with each of the three types of encephalitis. The results suggested that the inflammatory factors with a potential causal relationship with viral encephalitis were caspase 8, C-X-C motif chemokine 6, interleukin-10, interleukin-15 receptor subunit alpha, interleukin-7, and TNF-beta. Inflammatory factors potentially causally associated with acute disseminated encephalomyelitis are beta-nerve growth factor, cystatin D, interleukin-7,
Latency-associated peptide transforming growth factor beta 1,and neurotrophin-3.Inflammatory factors potentially causally associated with autoimmune encephalitis are C–C motif chemokine 25, hepatocyte growth factor, latency-associated peptide transforming growth factor beta 1, programmed cell death 1 ligand 1, sulfotransferase 1A1, and tumor necrosis factor.

Conclusion

This finding identifies potential causal effects of certain circulating inflammatory factors on susceptibility to three types of encephalitis. It also suggests the therapeutic potential of modulating the levels of these cytokines. A basis for further research is provided.
背景:细胞因子是免疫反应的强效分子。它们在炎症部位发挥作用,并在血液中循环。然而,有关脑炎和循环炎症蛋白的研究却很少:本研究采用孟德尔随机法(MR)探讨了 91 种循环炎症蛋白对 3 种不同类型脑炎的潜在因果效应。研究采用了 Steiger、MR-Egger、加权中位数和逆方差加权(IVW)方法对因果效应进行了检验。IVW 方法主要用于结果解释。此外,我们还进行了敏感性分析,包括异质性评估、水平多效性和 "Leave-one-out "技术:我们对 91 种循环炎症蛋白与三种脑炎的因果关系进行了 MR 分析。结果表明,与病毒性脑炎有潜在因果关系的炎症因子是caspase 8、C-X-C motif趋化因子6、白细胞介素-10、白细胞介素-15受体亚基α、白细胞介素-7和TNF-β。可能与急性播散性脑脊髓炎有关的炎症因子有:β-神经生长因子、胱抑素 D、白细胞介素-7、潜伏期相关肽转化生长因子β1 和神经营养素-3。与自身免疫性脑炎有潜在因果关系的炎症因子包括 C-C motif 趋化因子 25、肝细胞生长因子、潜伏期相关肽转化生长因子 beta 1、程序性细胞死亡 1 配体 1、磺基转移酶 1A1 和肿瘤坏死因子:这一发现确定了某些循环炎症因子对三种脑炎易感性的潜在因果效应。结论:这一发现确定了某些循环炎症因子对三种脑炎易感性的潜在因果关系,同时也表明了调节这些细胞因子水平的治疗潜力。为进一步研究提供了依据。

Objectives

Previous studies have suggested the associations between systemic inflammation and the risk of frailty, but causal relationships between them remain not well established. We conducted a bi-directional Mendelian randomization (MR) analysis to investigate the causal links between systemic inflammatory regulators and frailty.

Methods

Genetic variants associated with systemic inflammatory regulators were obtained from a comprehensive genetic study on 41 circulating cytokines, such as interleukin-4 (IL-4), eotaxin, and macrophage inflammatory protein-1β (MIP1β). We integrated summary-level data on frailty from two independent genetic studies on frailty index (FI) and Fried frailty score (FFS). The inverse-variance weighted method was used to assess the causal estimate. Sensitivity and heterogeneity analysis was performed to evaluate the stability of the estimates. The false discovery rate (FDR) method was used for P value adjustment of multiple comparisons.

Results

Genetically elevated levels of MIP1β and decreased levels of eotaxin were suggestively associated with increased FI (MIP1β: β = 0.016, Praw = 0.006, PFDR = 0.083; eotaxin: β = -0.030, Praw = 0.007, PFDR = 0.083) and FFS (MIP1β: β = 0.008, Praw = 0.027, PFDR = 0.247; eotaxin: β = -0.015, Praw = 0.014, PFDR = 0.247). In contrast, genetically predicted FI was suggestively associated with decreased levels of IL-4 (β = -0.395, Praw = 0.040, PFDR = 0.638) and platelet-derived growth factor BB (PDGF-BB, β = -0.385, Praw = 0.047, PFDR = 0.638) and increased levels of stem cell factor (SCF, β = 0.527, Praw = 0.005, PFDR = 0.204). Similar results were obtained from different sensitivity analysis.

Conclusions

The present study demonstrates that increased MIP-1β levels and decreased eotaxin levels might lead to a higher risk of frailty, whereas frailty might reduce the levels of IL-4 and PDGF-BB and increase the levels of SCF.
研究目的以往的研究表明,全身性炎症与虚弱风险之间存在关联,但它们之间的因果关系仍未得到很好的证实。我们进行了一项双向孟德尔随机化(MR)分析,以研究全身炎症调节因子与虚弱之间的因果关系:与全身性炎症调节因子相关的遗传变异来自于对 41 种循环细胞因子(如白细胞介素-4(IL-4)、依他霉素和巨噬细胞炎症蛋白-1β(MIP1β))的综合遗传研究。我们整合了两项独立遗传研究中关于虚弱指数(FI)和弗里德虚弱评分(FFS)的虚弱汇总数据。采用逆方差加权法评估因果关系估计值。为评估估计值的稳定性,进行了敏感性和异质性分析。多重比较的P值调整采用了错误发现率(FDR)法:结果:MIP1β基因水平的升高和 eotaxin 基因水平的降低与 FI 的增加呈提示性相关(MIP1β:β = 0.016,Praw = 0.006,PFDR = 0.083; eotaxin: β = -0.030, Praw = 0.007, PFDR = 0.083) 和 FFS (MIP1β: β = 0.008, Praw = 0.027, PFDR = 0.247; eotaxin: β = -0.015, Praw = 0.014, PFDR = 0.247)。相比之下,遗传预测的 FI 与 IL-4 水平下降(β = -0.395,Praw = 0.040,PFDR = 0.638)和血小板衍生生长因子 BB(PDGF-BB,β = -0.385,Praw = 0.047,PFDR = 0.638)以及干细胞因子水平上升(SCF,β = 0.527,Praw = 0.005,PFDR = 0.204)密切相关。不同的敏感性分析也得出了类似的结果:本研究表明,MIP-1β水平升高和eotaxin水平降低可能导致更高的虚弱风险,而虚弱可能降低IL-4和PDGF-BB的水平,增加SCF的水平。

Acute pancreatitis (AP) is a lethal inflammatory disease of the pancreas. Its pathogenesis remains obscure and specific treatments are lacking. An increase in Interleukin-10 (IL-10) in the early stage of AP patients is closely related to AP severity. In Coxsackievirus B3 (CVB3) induced murine AP model, we found early IL-10 increased viral replication and pancreatic inflammation, yet the cellular source of IL-10 and the immunomodulatory role of neutrophils during viral infection remains unknown. Here we show that CVB3 infection enhanced neutrophil infiltration and IL-10 expression in the pancreas at day3 post infection (p.i.). Neutrophils served as an important early source of pancreatic IL-10 at the initiation of infection. Day3 pancreas extracts (D3P) also induced bone-marrow derived neutrophils (BMneu) to secrete IL-10. Adoptive transfer of D3P-pretreated BMneu into IL-10 KO mice increased viral replication and pancreas histopathology, which effect was blunted by the absence of IL-10 in BMneu. Mechanically, IL-10+ neutrophil increased IL-10R1 expression on MΦs and activated STAT3-IL-6/IL-10 signaling cascade while decreased IL-12 and MHC II expression in MΦs, thus impairing IFN-γ+Granzyme B+CD8+T cell activation and viral clearance. Adoptive transferring infected mice with activated CD8+T cells 4 days p.i. attenuated viral load and AP pathology indicating an AP-protective effect. Our findings document a novel immunoregulatory function of neutrophils in acute CVB3 infection, in which neutrophil-derived IL-10 impairs anti-viral CD8+T activation, and amplifies intrapancreatic inflammation via activating MΦ STAT3-IL-6 signaling cascade. An IL-10-targeting option is suggested for the future treatment of viral AP.
急性胰腺炎(AP)是一种致命的胰腺炎症性疾病。其发病机制仍不明确,也缺乏特效治疗方法。急性胰腺炎患者早期白细胞介素-10(IL-10)的增加与急性胰腺炎的严重程度密切相关。在柯萨奇病毒 B3(CVB3)诱导的小鼠 AP 模型中,我们发现早期 IL-10 会增加病毒复制和胰腺炎症,但 IL-10 的细胞来源以及中性粒细胞在病毒感染过程中的免疫调节作用仍不清楚。在这里,我们发现CVB3感染后第3天(p.i.),中性粒细胞浸润和IL-10在胰腺中的表达增强。在感染开始时,中性粒细胞是胰腺IL-10的重要早期来源。第3天的胰腺提取物(D3P)还能诱导骨髓衍生的中性粒细胞(BMneu)分泌IL-10。将经D3P处理的骨髓中性粒细胞移植到IL-10 KO小鼠体内会增加病毒复制和胰腺组织病理学,而骨髓中性粒细胞中缺乏IL-10会减弱这种效应。从机制上讲,IL-10+中性粒细胞增加了MΦs上IL-10R1的表达,激活了STAT3-IL-6/IL-10信号级联,同时降低了MΦs上IL-12和MHC II的表达,从而损害了IFN-γ+粒酶B+CD8+T细胞的活化和病毒清除。用活化的CD8+T细胞于4天后收养转移感染小鼠,可减轻病毒载量和AP病理变化,这表明AP具有保护作用。我们的研究结果证明了中性粒细胞在CVB3急性感染中的新型免疫调节功能,其中中性粒细胞衍生的IL-10会损害CD8+T的抗病毒活化,并通过激活MΦ STAT3-IL-6信号级联放大胰腺内炎症。这为未来治疗病毒性 AP 提出了一种 IL-10 靶向方案。

Aneurysmal subarachnoid hemorrhage (aSAH) is a hemorrhagic cerebrovascular disease that seriously jeopardizes human life and health. Some studies have shown that although Interleukin-4 (IL-4) acts as an anti-inflammatory factor, IL-4 levels are elevated when the disease occurs. This study focuses on exploring the relationship between IL and 4 concentrations in the serum and cerebrospinal fluid (CSF) and poor outcome in patients with aSAH. This study was a prospective observational study and 210 aSAH patients who met the inclusion criteria were divided into two groups according to the mRS score at 3 months after discharge, and 210 healthy people were selected as controls. The IL-4 concentrations were quantitatively determined with enzyme-linked adsorption assay (ELISA). We can draw a conclusion that Serum and CSF IL-4 concentrations are generally elevated in patients with poor outcome(P < 0.05), and the CSF IL-4 concentration decreased gradually over the progress of time (P < 0.05). The IL-4 concentration in the CSF was positively correlated with age, platelet-lymphocyte ratio (PLR), C-reactive protein (CRP), Hunt-Hess grade, mRS score, and World Federation of Neurological Surgeons score (WFNS) (P < 0.0001). Additionally, IL-4 concentrations in the CSF were correlated with complications such as intracranial infection (P = 0.01), cerebral edema (P < 0.01), hydrocephalus (P = 0.02), and complications by DCI (P = 0.02). Elevated serum and CSF concentrations of IL-4 may associated with the outcome of aSAH and may be a candidate early biomarkers for outcome of aSAH.
动脉瘤性蛛网膜下腔出血(aSAH)是一种严重危害人类生命和健康的出血性脑血管疾病。有研究表明,虽然白细胞介素-4(IL-4)是一种抗炎因子,但当疾病发生时,IL-4水平会升高。本研究主要探讨血清和脑脊液(CSF)中 IL 和 4 浓度与 aSAH 患者不良预后之间的关系。本研究为前瞻性观察研究,根据出院后3个月的mRS评分将符合纳入标准的210名aSAH患者分为两组,并选择210名健康人作为对照。用酶联吸附测定法(ELISA)定量测定了 IL-4 的浓度。我们可以得出结论:血清和脑脊液 IL-4 浓度在预后不良的患者中普遍升高(P<0.05)。

Purpose

This exploratory study investigates the possible relationship between inflammation and thrombosis in cervical cancer patients in South Africa, highlighting the need for improved thrombotic risk profiling.

Methods

Thromboelastography (TEG) was used to assess coagulation parameters in platelet-poor plasma (PPP) from a small cohort of late-stage (III and IV) cervical cancer patients (n = 19) and healthy controls (n = 15). Parameters assessed included clotting time, clot formation speed, and clot strength. A Luminex Multiplex assay was used to measure interferon-γ (IFN-γ), interleukin-1β (IL-1β), IL-6, vascular endothelial growth factor-A (VEGF-A), and tumour necrosis factor-α (TNF-α) in PPP. Haematological profiles were also evaluated.

Results

Cervical cancer patients displayed a significantly shortened clotting time (p = 0.0044) and increased clot strength (p = 0.0003), suggesting enhanced coagulation. IL-1β was notably elevated (p = 0.0200), consistent with an inflammatory environment. Higher lymphocyte, neutrophil, and platelet counts (p = 0.0162, 0.0420, and 0.0374, respectively) were observed, indicating a possible prothrombotic state.

Conclusion

These findings suggest a potential link between inflammation and thrombosis in cervical cancer patients. However, due to this study’s small sample size and exploratory nature, direct relationships between these factors have yet to be definitively established and remain speculative. Thrombotic risk profiling may still offer value in managing patients, but further investigation is required to confirm these preliminary observations.
目的:这项探索性研究调查了南非宫颈癌患者的炎症与血栓形成之间可能存在的关系,强调了改进血栓形成风险分析的必要性:方法:采用血栓弹性成像(TEG)技术评估一小群晚期(III 和 IV 期)宫颈癌患者(19 人)和健康对照组(15 人)贫血小板血浆(PPP)中的凝血参数。评估参数包括凝血时间、凝血形成速度和凝血强度。使用 Luminex Multiplex 分析法检测 PPP 中的干扰素-γ(IFN-γ)、白细胞介素-1β(IL-1β)、IL-6、血管内皮生长因子-A(VEGF-A)和肿瘤坏死因子-α(TNF-α)。此外,还对血液学特征进行了评估:结果:宫颈癌患者的凝血时间明显缩短(p = 0.0044),凝血强度增加(p = 0.0003),表明凝血功能增强。IL-1β 明显升高(p = 0.0200),与炎症环境一致。观察到淋巴细胞、中性粒细胞和血小板计数升高(分别为 p = 0.0162、0.0420 和 0.0374),表明可能存在促血栓形成状态:结论:这些研究结果表明,宫颈癌患者的炎症与血栓形成之间存在潜在联系。结论:这些研究结果表明,宫颈癌患者的炎症与血栓形成之间存在潜在联系。然而,由于本研究的样本量较小,且属于探索性研究,因此这些因素之间的直接关系尚未明确确定,仍属于推测。血栓形成风险分析可能对患者的管理仍有价值,但还需要进一步的研究来证实这些初步观察结果。

Leishmaniasis, a broad range of parasitic diseases, caused by Leishmania which is a flagellated intracellular protozoan parasite of the family Trypanosomatidae. The severity of leishmaniasis diseases ranges from minor cutaneous lesions to severe visceral illnesses that can be disfiguring and life-threatening. Cytokines are glycoprotein molecules produced by various cells in response to various immunological triggers. They regulate the body’s innate and adaptive immunological responses. The aim of this study was to clarify the association of serum level and polymorphisms of IFN-γ with susceptibility to cutaneous leishmaniasis (CL). The whole blood 200 samples were collected from patients and controls from Diyala Governorate/ Iraq from October 2022 to February 2023 which were used to measure IFN-γ polymorphisms using High Resolution Melting technique. Enzyme-linked immunosorbent assay was used to detect the serum level of IFN-γ. The findings of this investigation showed that the IFN-γ serum concentration elevated significantly in patients compared to controls (P < 0.01). Also, the study found that the highest mean level IFN-γ concentrations were found in adults aged 46–55 years old for patients compared with controls with significant differences (P < 0.01). While, no significant differences were observed in the rest age groups except children aged 5–15 years old. Additionally, significant differences between patients and controls were revealed by polymorphisms data in all genetic models for genotypes GA, AA, (GA + AA) and allele A with (P < 0.01) and OR > 1. However, the distribution of IFN-γ serum levels by SNP (rs2069705) demonstrated no differences between genotypes except GG genotype which has significant differences for patients comparing to the same genotype in controls. Taking together, the SNP for IFN-γ (rs2069705) could be a risk factor for susceptibility infection with CL. Also, considered the mutant allele A as a risk allele and genotype AA in codominant genetic model as more risk factor than the genotype GA.
利什曼病(Leishmaniasis)是由利什曼原虫(Leishmania)引起的一种广泛的寄生虫病,利什曼原虫是锥虫科(Trypanosomatidae)的一种鞭毛细胞内原生动物寄生虫。利什曼病的严重程度从轻微的皮肤损伤到严重的内脏疾病不等,可导致毁容和危及生命。细胞因子是各种细胞针对各种免疫触发因素产生的糖蛋白分子。它们调节机体的先天性和适应性免疫反应。本研究旨在阐明 IFN-γ 的血清水平和多态性与皮肤利什曼病(CL)易感性的关系。研究人员于 2022 年 10 月至 2023 年 2 月期间从伊拉克迪亚拉省的患者和对照组中采集了 200 份全血样本,并使用高分辨率熔融技术测量了 IFN-γ 的多态性。酶联免疫吸附试验用于检测血清中 IFN-γ 的水平。调查结果显示,与对照组相比,患者的 IFN-γ 血清浓度明显升高(P < 0.01)。研究还发现,与对照组相比,46-55 岁成人患者的 IFN-γ 浓度平均水平最高,且差异显著(P <0.01)。而除 5-15 岁儿童外,其余年龄组均无明显差异。此外,在所有基因模型中,基因型为 GA、AA、(GA + AA)和等位基因 A 的多态性数据均显示患者和对照组之间存在显著差异(P <0.01),OR >1。然而,SNP(rs2069705)的 IFN-γ 血清水平分布显示,除了 GG 基因型与对照组的相同基因型相比,患者与对照组之间存在显著差异外,其他基因型之间没有差异。综合来看,IFN-γ 的 SNP(rs2069705)可能是感染 CL 的一个风险因素。此外,突变等位基因 A 被认为是风险等位基因,在共显遗传模型中,基因型 AA 比基因型 GA 更具风险性。

Human interferon (IFN) lambda (IFNL, IFN-L or IFN-λ) locus has several functional genetic variants but their role in regulating in vivo gene expression, and whether they associate with antiviral states in healthy individuals, is not clear. In this study, we recruited ∼550 healthy individuals belonging to both sexes, genotyped them for several IFNL genetic variants and measured, by qPCR, the expression of IFNL2/3, IFNL4 and four IFN-stimulated genes (ISGs) (MX1, OAS1, ISG15 and RSAD2) from their peripheral blood mononuclear cells (PBMC) both before and after stimulation with a viral mimic, poly I: C. We also measured secreted levels of several cytokines including IFN-λ1 and IFN-λ3 in poly I:C stimulated PBMCs. We found that males secrete higher levels of IFN-λs than females. The IFNL3/4 genetic variants significantly associated with secreted levels of both IFN-λ1 and IFN-λ3 in opposite directions, only in males. While the IFNL3/4 variants significantly associated with ISG expression either in basal or poly I:C induced or in both states, the direction of effect was opposite for the two sexes, suggesting that sex was a strong effect modifier. We did not see this trend in the association of ISG expression with the IFNL1 polymorphism, rs7247086, whose association with ISG expression and secreted IFN-λ3 levels was seen in females but not in males. Further, expression of several genes was associated with the IFN-λ4 activity-modifying variant rs117648444. However, we neither saw any strong correlation between levels of IFN-λ1/3 and ISG expression, nor did we see any strong evidence of IFNL4 expression that could be responsible for the association between ISG expression and IFNL genetic variants. These results suggest that there are complex interactions involving gender, IFN-λs, IFN-λ genetic variants and antiviral states in humans.
人类干扰素(IFN)λ(IFNL、IFN-L 或 IFN-λ)位点有多种功能基因变异,但它们在调节体内基因表达方面的作用以及是否与健康人的抗病毒状态有关尚不清楚。在这项研究中,我们招募了 550 名男女健康人,对他们进行了多种 IFNL 基因变异的基因分型,并通过 qPCR 测定了他们的外周血单核细胞(PBMC)中 IFNL2/3、IFNL4 和四个 IFN 刺激基因(ISGs)(MX1、OAS1、ISG15 和 RSAD2)在病毒模拟物 poly I: C 刺激前后的表达情况。我们还测量了多聚 I:C 刺激的 PBMC 中几种细胞因子的分泌水平,包括 IFN-λ1 和 IFN-λ3。我们发现,男性分泌的 IFN-λs 水平高于女性。IFNL3/4基因变异与IFN-λ1和IFN-λ3的分泌水平明显相关,但方向相反,仅在男性中存在。虽然IFNL3/4基因变异与ISG在基础状态、poly I:C诱导状态或两种状态下的表达均有显著相关性,但两种性别的影响方向却相反,这表明性别是一个强有力的效应调节因子。我们没有发现 ISG 表达与 IFNL1 多态性 rs7247086 的关系有这种趋势,IFNL1 多态性与 ISG 表达和分泌的 IFN-λ3 水平的关系在女性中可见,而在男性中则没有。此外,多个基因的表达与 IFN-λ4 活性修饰变异 rs117648444 相关。然而,我们既没有看到 IFN-λ1/3 水平与 ISG 表达之间有任何强烈的相关性,也没有看到任何 IFNL4 表达的强烈证据可能是造成 ISG 表达与 IFNL 基因变异之间关联的原因。这些结果表明,人类的性别、IFN-λ、IFN-λ基因变异和抗病毒状态之间存在着复杂的相互作用。

Objectives

Carpal tunnel syndrome (CTS) and certain inflammatory cytokines have been linked in observational studies; however, the exact causative linkages remain unknown. The purpose of this study is to investigate any possible link between the onset of CTS and 91 inflammatory cytokines.

Methods

A two-sample bidirectional Mendelian randomization (MR) approach was used in this investigation. 91 circulating inflammatory cytokines’ genetic variants were retrieved from the European ancestry genome-wide association study (GWAS) database. From germline GWAS, summary data for 24,766 CTS patients and 360,538 controls were gathered. The instrumental variables were single nucleotide polymorphisms (SNPs) that were highly correlated with the 91 inflammatory cytokines. The random-effects inverse-variance weighted (IVW) approach was employed in the primary analysis, and multiple comparisons were subjected to the Bonferroni correction. Sensitivity analysis was performed to evaluate the validity of the causal relationship.

Results

Our findings showed a negative correlation between CCL19, FGF-19, IL-5, TGF-alpha, TRAIL, and the risk of CTS. Specifically, CCL19 (odds ratio [OR]: 0.944, 95 % confidence interval [CI]: 0.894–0.996, p = 0.0349), FGF-19 (OR: 0.940, 95 % CI: 0.894–0.987, p = 0.0133), IL-5 (OR: 0.936, 95 % CI: 0.885–0.990, p = 0.0212), TGF-alpha (OR: 0.902, 95 % CI: 0.838–0.970, p = 0.0057), and TRAIL (OR: 0.926, 95 % CI: 0.881–0.974, p = 0.0026) were inversely related to CTS risk. Conversely, CCL20, IL-2RB, and IL-6 were positively associated with an increased risk of CTS. Specifically, CCL20 (OR: 1.072, 95 % CI: 1.005–1.142, p = 0.0334), IL-2RB (OR: 1.067, 95 % CI: 1.001–1.137, p = 0.0463), and IL-6 (OR: 1.088, 95 % CI: 1.005–1.177, p = 0.0365) were positively correlated with CTS risk. Reverse Mendelian randomization analyses indicated no evidence of a reverse causal relationship between CTS and inflammatory cytokines.

Conclusion

According to this study, there is a causal link between CTS and certain inflammatory cytokines, which suggests that these cytokines may be important in the pathophysiology of CTS. To confirm these results and investigate the specific function of these cytokines in the beginning and development of CTS, more investigation is necessary.
目的 在观察性研究中,腕管综合征(CTS)与某些炎症细胞因子有关联;但确切的因果关系仍不清楚。本研究旨在调查 CTS 发病与 91 种炎症细胞因子之间可能存在的联系。从欧洲血统全基因组关联研究(GWAS)数据库中提取了 91 种循环炎性细胞因子的遗传变异。从种系全基因组关联研究中收集了 24,766 名 CTS 患者和 360,538 名对照组的汇总数据。工具变量是与 91 种炎症细胞因子高度相关的单核苷酸多态性(SNPs)。主要分析采用随机效应逆方差加权(IVW)方法,多重比较采用 Bonferroni 校正。我们的研究结果表明,CCL19、FGF-19、IL-5、TGF-α、TRAIL 与罹患 CTS 的风险呈负相关。具体而言,CCL19(几率比 [OR]:0.944,95% 置信区间 [CI]:0.894-0.996,p = 0.0349)、FGF-19(OR:0.940,95 % CI:0.894-0.987,p = 0.0133)、IL-5(OR:0.936,95 % CI:0.885-0.990,p = 0.0212)、TGF-α(OR:0.902,95 % CI:0.838-0.970,p = 0.0057)和 TRAIL(OR:0.926,95 % CI:0.881-0.974,p = 0.0026)与 CTS 风险成反比。相反,CCL20、IL-2RB 和 IL-6 与 CTS 风险增加呈正相关。具体来说,CCL20(OR:1.072,95 % CI:1.005-1.142,p = 0.0334)、IL-2RB(OR:1.067,95 % CI:1.001-1.137,p = 0.0463)和 IL-6(OR:1.088,95 % CI:1.005-1.177,p = 0.0365)与 CTS 风险呈正相关。反向孟德尔随机分析表明,没有证据表明 CTS 与炎性细胞因子之间存在反向因果关系。要证实这些结果并研究这些细胞因子在 CTS 的起始和发展过程中的具体功能,还需要进行更多的研究。

Background

Previous studies indicated that pleural fluid complement C1q was helpful for diagnosing tuberculous pleural effusion (TPE), but the participants in these studies were young. The diagnostic accuracy of C1q for TPE in elderly patients remains unknown. This study aimed to investigate the diagnostic accuracy of C1q for TPE in elderly patients.

Methods

We prospectively recruited patients with undiagnosed pleural effusion who visited the Affiliated Hospital of Inner Mongolia Medical University between September 2018 and July 2021. Their C1q in pleural fluid was detected, and the diagnostic accuracy of C1q was assessed by the receiver operating characteristic (ROC) curve analysis.

Results

The median ages of patients with TPE and non-TPE were 75 and 71 years, respectively. TPE patients had significantly higher C1q than non-TPE. The area under the ROC curve (AUC) of C1q was 0.67 (95 %CI: 0.51–0.82). At the threshold of 100 mg/L, C1q had a sensitivity of 0.44 (95 %CI: 0.19–0.69) and specificity of 0.79 (95 %CI: 0.71–0.86).

Conclusion

C1q in pleural fluid has low diagnostic accuracy for TPE in elderly patients.
背景以前的研究表明,胸腔积液补体C1q有助于诊断结核性胸腔积液(TPE),但这些研究的参与者都很年轻。C1q对老年患者TPE的诊断准确性仍不清楚。本研究旨在探讨C1q对老年患者TPE的诊断准确性。方法我们前瞻性地招募了2018年9月至2021年7月期间在内蒙古医科大学附属医院就诊的未确诊胸腔积液患者。结果TPE和非TPE患者的中位年龄分别为75岁和71岁。TPE患者的C1q明显高于非TPE患者。C1q的ROC曲线下面积(AUC)为0.67(95 %CI:0.51-0.82)。结论 胸腔积液中的 C1q 对老年患者 TPE 的诊断准确性较低。
