Background: Genetic variability of Helicobacter pylori is associated with various gastrointestinal diseases; however, little is known about interaction with sociodemographic in the development of premalignant lesions in Colombian patients.

Methods: An analytical study was conducted including cases (patients with gastric atrophy, intestinal metaplasia, and gastric dysplasia) and controls (patients with nonatrophic gastritis). Sociodemographic information was obtained using a questionnaire. Histopathological diagnosis was performed according to the Sydney System. The cagA and vacA genotypes were established using polymerase chain reaction in paraffin blocks. The effect of each variable on the study outcome (premalignant lesion) is presented as odds ratio (OR) and 95% CI. A p value of <0.05 was considered as statistically significant.

Results: The vacA/s1m1 genotype increases the risk of developing premalignant lesions of the stomach (OR: 3.05, 95% IC: 1.57-5.91, p=0.001). Age and educational level showed a positive interaction with the s1m1 genotype (adjusted OR: 3.68, 95% CI: 1.73-7.82, p=0.001). The cagA genotype was not correlated to the development of premalignant lesions of the stomach (OR: 1.32, 95% CI: 0.90-1.94, p=0.151).

Conclusions: The vacA genotype, age, and educational level are indicators of the risk of developing premalignant lesions of the stomach in the study population. Significance Statement. Genetic variability of H. pylori and sociodemographic information could be used to predict the risk of premalignant lesions in stomach in Colombian population.

背景:幽门螺杆菌的遗传变异与多种胃肠道疾病有关;然而,在哥伦比亚患者的恶性病变的发展与社会人口的相互作用知之甚少。方法:将病例(胃萎缩、肠化生和胃发育不良患者)和对照组(非萎缩性胃炎患者)进行分析研究。通过问卷调查获得社会人口统计信息。按照Sydney系统进行组织病理学诊断。采用石蜡块聚合酶链反应建立cagA和vacA基因型。每个变量对研究结果(癌前病变)的影响以比值比(OR)和95% CI表示。结果:vacA/s1m1基因型增加胃发生癌前病变的风险(OR: 3.05, 95% IC: 1.57 ~ 5.91, p=0.001)。年龄和受教育程度与s1m1基因型呈正相关(校正OR: 3.68, 95% CI: 1.73 ~ 7.82, p=0.001)。cagA基因型与胃癌前病变的发生无相关性(OR: 1.32, 95% CI: 0.90-1.94, p=0.151)。结论:vacA基因型、年龄和受教育程度是研究人群发生胃癌前病变风险的指标。意义的声明。幽门螺杆菌遗传变异和社会人口学信息可用于预测哥伦比亚人群胃癌前病变的风险。

Background: The goal of this systematic review and meta-analysis was analyzing published studies on the role of neutrophil to lymphocyte ratio (NLR) in infection and spatially spontaneous bacterial peritonitis (SBP) among cirrhotic patients.

Methods: PubMed, Web of Science, and Scopus were searched until May 24, 2022. The Newcastle-Ottawa scale was used for quality assessment.

Results: Of 14 studies included in our study, six studies were on infection with 2786 hospitalized cirrhotic patients, of whom 934 developed an infection. Other studies were on SBP with 1573 cirrhotic patients with ascites, of whom 557 developed SBP. The pooled results showed that there was no difference in NLR levels between hospitalized cirrhotic patients who developed infection compared to those who did not (random-effects model: SMD = 0.63, 95% CI = -0.01-1.27, p=0.054). However, cirrhotic patients with ascites who developed SBP had elevated levels of NLR compared to those who did not (random-effects model: SMD = 1.05, 95% CI = 0.52-1.57,p < 0.001). This difference remained significant in prospective studies (SMD = 0.94, 95% CI = 0.51-1.38,p < 0.001) but not in retrospective studies (SMD = 1.37, 95% CI = -0.56-3.29,p=0.165), in the subgroup analysis according to the study design. The pooled sensitivity of NLR was 92.07% (95% CI = 74.85%-97.84%) and the pooled specificity was 72.58% (95% CI = 57.72%-83.69%). The pooled positive likelihood ratio, negative likelihood ratio, DOR of NLR were 3.35(95%CI = 2.06-5.46), 0.10 (95%CI = 0.03-0.38), and 30.78 (95%CI = 7.01-135.04), respectively.

Conclusion: Our results support NLR to be a valid biomarker that can be readily integrated into clinical settings to help in the prevention and prediction of SBP among cirrhotic patients.

背景:本系统综述和荟萃分析的目的是分析已发表的关于中性粒细胞与淋巴细胞比率(NLR)在肝硬化患者感染和空间自发性细菌性腹膜炎(SBP)中的作用的研究。方法:检索PubMed、Web of Science、Scopus至2022年5月24日。采用纽卡斯尔-渥太华量表进行质量评估。结果:在纳入我们研究的14项研究中,6项研究涉及2786名住院肝硬化患者的感染,其中934人发生感染。其他研究对1573例肝硬化腹水患者的收缩压进行了研究,其中557例发生了收缩压。合并结果显示,发生感染的住院肝硬化患者与未发生感染的住院肝硬化患者的NLR水平无差异(随机效应模型:SMD = 0.63, 95% CI = -0.01-1.27, p=0.054)。然而,与未发生SBP的肝硬化腹水患者相比,发生SBP的患者NLR水平升高(随机效应模型:SMD = 1.05, 95% CI = 0.52-1.57,p < 0.001)。这种差异在前瞻性研究(SMD = 0.94, 95% CI = 0.51-1.38,p < 0.001)中仍然显著,但在回顾性研究(SMD = 1.37, 95% CI = -0.56-3.29,p=0.165)中,根据研究设计进行亚组分析时,这种差异不显著。NLR的合并敏感性为92.07% (95% CI = 74.85% ~ 97.84%),合并特异性为72.58% (95% CI = 57.72% ~ 83.69%)。NLR的合并阳性似然比为3.35(95%CI = 2.06 ~ 5.46),阴性似然比为0.10 (95%CI = 0.03 ~ 0.38), DOR为30.78 (95%CI = 7.01 ~ 135.04)。结论:我们的研究结果支持NLR是一种有效的生物标志物,可以很容易地整合到临床环境中,帮助预防和预测肝硬化患者的收缩压。

Cirrhosis-induced clinically significant portal hypertension (CSPH) is a fatal disease. Early detection of CSPH is vitally important to reduce the patients' mortality rate. In this study, combined with three-dimensional image construction technology and computational fluid dynamics (CFD), an image-based flow resistance analysis was proposed. The flow resistance analysis was performed for nine cirrhosis patients with CSPH and ten participants without liver diseases, respectively. The results showed that the flow resistance coefficient of the portal vein system in CSPH patients was significantly lower than that in the control group (0.97 ± 0.11 Pa/(mL/s) for CSPH patients; 1.80 ± 0.40 Pa/(mL/s) for the control group; P = 0.028). In contrast, although main portal vein dilation was found in CSPH patients, the cross-sectional area enlargement was not statistically significant (186.01 ± 57.48 mm2 for CSPH patients; 166.26 ± 33.74 mm2 for the control group; P = 0.39). The research outcomes indicated that the flow resistance analysis was more sensitive than the commonly used vessel size measurement in the detection of CSPH. In summary, we suggest using flow resistance analysis as a supplementary noninvasive method to detect cirrhosis patients with CSPH.

肝硬化引起的临床显著性门脉高压(CSPH)是一种致命的疾病。早期发现CSPH对降低患者死亡率至关重要。本研究将三维图像构建技术与计算流体力学(CFD)相结合,提出了一种基于图像的流阻分析方法。分别对9例肝硬化合并CSPH患者和10例无肝脏疾病的参与者进行了血流阻力分析。结果表明:CSPH患者门静脉系统血流阻力系数显著低于对照组(0.97±0.11 Pa/(mL/s));对照组为1.80±0.40 Pa/(mL/s);P = 0.028)。相比之下,CSPH患者门静脉主干扩张,但横截面积扩大无统计学意义(186.01±57.48 mm2);对照组为166.26±33.74 mm2;P = 0.39)。研究结果表明,在CSPH检测中,流动阻力分析比常用的血管尺寸测量更敏感。综上所述,我们建议将血流阻力分析作为一种辅助的无创方法来检测肝硬化合并CSPH患者。

Objective: Intrahepatic cholangiocarcinoma (iCCA) is a primary liver malignancy with a poor prognosis and limited treatment. Cisplatin with gemcitabine is used as the standard first-line chemotherapy regimen; however, there is still no robust evidence for second-line and successive treatments. Although preliminary evidence suggests a vital role of precision therapy or immunotherapy in a subset of patients, the gene alteration rate is relatively low. Herein, we explored the second-line and successive treatments using hepatic arterial infusion chemotherapy (HAIC) based on FOLFIRI after the failure of gemcitabine and platinum combined with target and immunotherapy in refractory CCAs.

Methods: Advanced patients with iCCAs confirmed by diagnostic pathology, who progressed at least on a gemcitabine/platinum doublet and/or other systemic chemotherapy combined with target therapy and immune checkpoint inhibitor, were included. All patients received infusional 5-fluorouracil/leucovorin with irinotecan (FOLFIRI) via HAIC until progression or unacceptable toxicity. The primary objective was the feasibility of treatment, with secondary objectives of disease control rate (DCR) and 6-month survival rate.

Results: A total of 9 iCCA patients treated between Dec 2020 and May 2021 were enrolled; 2 patients suffered from distant metastasis, while 7 had local lymph node metastasis and portal vein or hepatic vein invasion. HAIC was delivered as second-line therapy in 6/9 patients, while a third or successive therapy in 3/9 patients. The patients accepted an average of 2.90 ± 1.69 cycles of HAIC. The objective response rate was 22.2%; the disease control rate was 55.5% (5/9); median progression-free survival was 5 months; and 6-month survival rate was 66.7% (6/9).

Conclusions: Our results provide preliminary evidence that HAIC based on FOLFIRI regimen is efficient and safe in some patients progressing after previous treatment. Therefore, HAIC may be a promising and valuable complementary therapy for advanced CCAs as a second-line and successive therapy. Otherwise, the combination of HAIC with precision medicine may improve clinical benefits (clinical registration number: 2021BAT4857).

目的:肝内胆管癌(iCCA)是一种预后差且治疗有限的原发性肝脏恶性肿瘤。顺铂联合吉西他滨是标准的一线化疗方案;然而,仍然没有强有力的证据表明二线和连续治疗。虽然初步证据表明精确治疗或免疫治疗在一部分患者中起着至关重要的作用,但基因变化率相对较低。本研究探讨了吉西他滨和铂联合靶向和免疫治疗难治性cca失败后,基于FOLFIRI的肝动脉输注化疗(HAIC)的二线和后续治疗。方法:纳入诊断病理证实的晚期iCCAs患者,这些患者至少在吉西他滨/铂双药和/或其他全身化疗联合靶向治疗和免疫检查点抑制剂方面进展。所有患者均通过HAIC输注5-氟尿嘧啶/亚叶酸钙联合伊立替康(FOLFIRI),直至病情进展或出现不可接受的毒性。主要目标是治疗的可行性,次要目标是疾病控制率(DCR)和6个月生存率。结果:共有9例iCCA患者在2020年12月至2021年5月期间接受治疗;2例远处转移,7例局部淋巴结转移并侵犯门静脉或肝静脉。在6/9的患者中,HAIC作为二线治疗,而在3/9的患者中,HAIC作为第三或连续治疗。患者平均接受2.90±1.69周期的HAIC。客观有效率为22.2%;疾病控制率为55.5% (5/9);中位无进展生存期为5个月;6个月生存率为66.7%(6/9)。结论:我们的研究结果提供了初步证据,证明基于FOLFIRI方案的HAIC对于一些既往治疗后进展的患者是有效和安全的。因此,HAIC可能是晚期CCAs的一种有前途和有价值的补充治疗,作为二线和连续治疗。否则,HAIC与精准医疗的结合可能会提高临床效益(临床注册号:2021BAT4857)。

Introduction: Autoimmune hepatitis (AIH) is a chronic liver disease with a relevant inflammatory component and an unknown etiology. Evidence for clinical characteristics and risk factors in large cohorts of patients with acute AIH (AAIH) is lacking. We clinically characterized patients with AAIH, the prevalence of a combined adverse outcome (death or liver transplantation (LT)), and its risk factors.

Methods: A retrospective study of adult patients diagnosed with AAIH at three centers (Santiago, Chile; 2000-2018) was conducted. Clinical and laboratory characteristics were obtained. A liver biopsy was performed for all patients. Descriptive statistics and logistic regression models were used.

Results: A total of 126 patients were admitted; 77% were female, 33 (26.2%) had a severe presentation, and 14 (11.1%) had a fulminant presentation. Overall, 24 patients (19.0%) lacked typical autoantibodies, and 26.2% had immunoglobulin G levels in the normal range. The most frequent histological findings were plasma cells (86.5%), interface hepatitis (81.7%), and chronic hepatitis (81.0%). Rosettes were uncommon (35.6%). Advanced fibrosis was present in 27% of patients. Combined adverse outcomes occurred in 7.9% of cases, all fulminant with histological cholestasis. Alkaline phosphatase, bilirubin, and prothrombin less than 50% were independent risk factors for in-hospital death or LT (p value <0.05). Although corticosteroid treatment was associated with better outcomes (OR 0.095, p value = 0.013), more severe patients were less likely to receive this therapy. Discussion. In this large cohort of patients with AAIH, clinical characteristics differ from those reported in patients with chronic AIH. Fulminant hepatitis, histological cholestasis, alkaline phosphatase, bilirubin, and prothrombin were associated with death/LT.

自身免疫性肝炎(AIH)是一种慢性肝脏疾病,具有相关的炎症成分和未知的病因。大量急性AIH (AAIH)患者的临床特征和危险因素缺乏证据。我们对AAIH患者的临床特征、综合不良结局(死亡或肝移植)的发生率及其危险因素进行了分析。方法:对三个中心诊断为AAIH的成年患者(智利圣地亚哥;2000-2018年)。获得临床和实验室特征。所有患者均行肝活检。采用描述性统计和逻辑回归模型。结果:共收治126例患者;77%为女性,33例(26.2%)有严重表现,14例(11.1%)有暴发性表现。总体而言,24例患者(19.0%)缺乏典型的自身抗体,26.2%的患者免疫球蛋白G水平在正常范围内。最常见的组织学表现为浆细胞(86.5%)、界面肝炎(81.7%)和慢性肝炎(81.0%)。莲座不常见(35.6%)。27%的患者存在晚期纤维化。7.9%的病例发生了联合不良后果,所有病例均伴有组织学胆汁淤积。碱性磷酸酶、胆红素和凝血酶原低于50%是院内死亡或LT的独立危险因素(p值p值= 0.013),重症患者接受此治疗的可能性较小。讨论。在这个AAIH患者的大队列中,临床特征与慢性AIH患者的报道不同。暴发性肝炎、组织学胆汁淤积、碱性磷酸酶、胆红素和凝血酶原与死亡/LT相关。

Worldwide, colorectal cancer (CRC) is the second most diagnosed cancer in female and the third in men, arising from the epithelium of the colorectum. It is known that colorectal cancer is common in developed countries than in developing countries which may be due to inaccurate data on the existence of the disease in that region combined with embracing western lifestyle expressed by the current trend of changes in cultural, social, and lifestyle practices playing a major part in the etiology of CRC. The aim of this study was to document epidemiological, pathological characteristics, and prognostics determinants of patients diagnosed with CRC in Rwanda. The data from patients' files and reviewed glass slides for 101 cases all from Kigali University Teaching Hospital (CHUK) were statistically analyzed and patient characteristics were described as mean and frequency accordingly. Comparisons were performed using chi square tests, Fisher's exact test and odds ratio with 95% confidence interval (CI). Survival curves were plotted using the Kaplan-Meier method, and log-rank test was used to assess the statistical differences in the observed survival curves by each categorical variable. A P value < 0.05 was considered statistically significant. Statistical analyses were performed using Statistical Product and Service Solutions (SPSS), GraphPad Prism, and MedCalc, accordingly. Mean age of the participants was 54.26 years, the main symptom was rectal bleeding (46.5%), rectal adenocarcinoma NOS represented 40.6%, conventional adenocarcinoma was 60.4%, most tumors were of Grade II (54.5%), most common stage was pT3N0 (20.8%), resection margins were free at 71.3%, lympho-vascular invasion was 49.5% of cases, a high immune response was in 71.3% of cases and of 101cases, and 55.4% were still alive at the end of the data collection, with 29.3% of patients have overall survival of 5 years. Prognostic determinants also affect the outcome in this study and overall survival period was 3 years for CRC diagnosed in Rwanda.

Based on an experience of more than 50 years in the treatment of portal hypertension (PHT), the authors review and analyze the evolution of the surgical portocaval shunt (PCS). We would like to provide an insight into the past of PCS, in order to compare it with the current state of the treatment of PHT complications. As a landmark of the past, we shall present statistics of more than 500 cases of PHT operated between 1968 and 1983. From this group, 238 patients underwent surgical portocaval shunting during a fifteen-year period. The behavior of the portal hemodynamics following PCS was studied and the postoperative decrease in portal pressure (PP), as well as the residual PP, were recorded. The portal manometric determinations were made by electronic recordings using the Hellige device and direct intraoperative recordings through the catheterization of a ramus in the portal area. The results of PCS are superposable, in terms of hemodynamic efficiency, with those of the intrahepatic shunt (TIPS-transjugular intrahepatic portosystemic shunt). The authors discuss the current place of PCS, in obvious decline in comparison with the situation 50 years ago. The current methods of controlling variceal bleeding represent obvious progress. PCS remains with very limited indications, in specific situations when the other therapeutic methods have failed or are not recommended.

基于50多年治疗门静脉高压症(PHT)的经验,作者回顾并分析了外科门静脉分流术(PCS)的发展。我们想提供一个深入了解过去的PCS,以便将其与目前治疗PHT并发症的状态进行比较。作为过去的一个里程碑,我们将介绍在1968年至1983年期间进行的500多个PHT病例的统计数据。在这一组中,在15年期间,238例患者接受了外科门静脉分流术。我们研究了PCS术后门静脉血流动力学的行为,并记录了门静脉压力(PP)的下降和残余PP。门静脉压力测定采用Hellige装置进行电子记录,术中通过门静脉分支导管直接记录。PCS在血流动力学效率方面与肝内分流术(tips -经颈静脉肝内门静脉分流术)的结果是重叠的。作者讨论了pc的现状,与50年前的情况相比,pc的情况明显下降。目前控制静脉曲张出血的方法取得了明显的进展。在其他治疗方法失败或不推荐的特定情况下,PCS的适应症非常有限。

Recipient Age Predicts 20-Year Survival in Pediatric Liver Transplant. 儿童肝移植患者年龄预测20年生存率
IF 2.7 4区 医学 Q2 Medicine Pub Date : 2022-09-17 eCollection Date: 2022-01-01 DOI: 10.1155/2022/1466602

Introduction: Pediatric liver transplant recipients have demonstrated excellent long-term survival. The purpose of this analysis is to investigate factors associated with 20-year survival to identify areas for improvement in patient care.

Methods: Kaplan-Meier with log-rank test as well as univariate and multivariate logistic regression methods were used to retrospectively analyze 4,312 liver transplant recipients under the age of 18 between September 30, 1987 and March 9, 1998. Our primary endpoint was 20-year survival among one-year survival.

Results: Logistic regression analysis identified recipient age as a significant risk factor, with recipients below 5 years old having a higher 20-year survival rate (p < 0.001). A preoperative primary diagnosis of a metabolic dysfunction was found to be protective compared to other diagnoses (OR 1.64, CI 1.20-2.25). African-American ethnicity (OR 0.71, CI 0.58-0.87) was also found to be a risk factor for mortality. Technical variant allografts (neither living donor nor cadaveric) were not associated with increased or decreased rates of 20-year survival.

Conclusions: Our analysis suggests that long-term survival is inversely correlated with recipient age following pediatric liver transplant. If validated with further studies, this conclusion may have profound implications on the timing of pediatric liver transplantation.

儿童肝移植受者表现出良好的长期生存。本分析的目的是调查与20年生存率相关的因素,以确定患者护理需要改进的领域。方法:采用Kaplan-Meier、log-rank检验以及单因素和多因素logistic回归方法对1987年9月30日至1998年3月9日期间的4312例18岁以下肝移植受者进行回顾性分析。我们的主要终点是1年生存率中的20年生存率。结果:Logistic回归分析发现受者年龄是一个重要的危险因素,5岁以下受者20年生存率更高(p < 0.001)。与其他诊断相比,术前对代谢功能障碍的初步诊断具有保护作用(OR 1.64, CI 1.20-2.25)。非裔美国人种族(OR 0.71, CI 0.58-0.87)也被发现是死亡率的危险因素。技术变异同种异体移植物(既不是活体供体也不是尸体供体)与20年生存率的增加或降低无关。结论:我们的分析表明,儿童肝移植后的长期生存率与受体年龄呈负相关。如果得到进一步的研究证实,这一结论可能对儿童肝移植的时机有深远的影响。

Background: Serum HBV-RNA levels can predict antiviral response in chronic hepatitis B (CHB) patients; however, its role in HBV-related ACLF (HBV-ACLF) remains unclear. Here, we determined its implications for HBV-ACLF.

Methods: Baseline serum HBV-RNA levels were retrospectively detected in HBV-ACLF and CHB patients. The association of serum HBV-RNA level with clinical outcomes was evaluated by performing multiple logistic regression. A nomogram was developed to formulate an algorithm incorporating serum HBV-RNA for predicting the survival of HBV-ACLF patients. After being discharged from the hospital, the HBV-ACLF patients were followed up for 36 weeks.

Results: In this study, 82 HBV-ACLF patients and 33 CHB patients were included. Serum HBV-RNA levels were significantly higher in CHB patients than in HBV-ACLF patients (4.15 ± 2.63 log10 copies/mL VS 5.37 ± 2.02 log10 copies/mL) (P < 0.05). Among the HBV-ACLF cases, patients with poor outcomes had lower serum HBV-RNA levels, but the difference was not significant. The area under the receiver operating characteristic curve of the serum HBV-RNA inclusive model was 0.745, superior to 0.66 from MELD scores (P < 0.05). During the follow-up for four weeks, the serum HBV-RNA levels, especially in the survival group, were found to be lower than the baseline levels.

Conclusions: Serum HBV-RNA levels were associated with disease severity and might predict the long-term clinical outcome of HBV-ACLF patients.

背景:血清HBV-RNA水平可以预测慢性乙型肝炎(CHB)患者的抗病毒反应;然而,其在hbv相关ACLF (HBV-ACLF)中的作用尚不清楚。在这里,我们确定了它对HBV-ACLF的影响。方法:回顾性检测HBV-ACLF和CHB患者血清HBV-RNA基线水平。通过多重逻辑回归评估血清HBV-RNA水平与临床结果的关系。我们开发了一个nomogram来制定一种结合血清HBV-RNA预测HBV-ACLF患者生存的算法。出院后,对HBV-ACLF患者随访36周。结果:本研究共纳入82例HBV-ACLF患者和33例CHB患者。CHB患者血清HBV-RNA水平显著高于HBV-ACLF患者(4.15±2.63 log10 copies/mL VS 5.37±2.02 log10 copies/mL) (P < 0.05)。在HBV-ACLF病例中,预后较差的患者血清HBV-RNA水平较低,但差异不显著。血清HBV-RNA包容性模型的受试者工作特征曲线下面积为0.745,优于MELD评分的0.66 (P < 0.05)。在为期四周的随访期间,血清HBV-RNA水平,特别是在生存组,被发现低于基线水平。结论:血清HBV-RNA水平与疾病严重程度相关,并可能预测HBV-ACLF患者的长期临床预后。

Misconceptions Drive COVID-19 Vaccine Hesistancy in Individuals with Inflammatory Bowel Disease. 误解导致炎症性肠病患者的COVID-19疫苗抗性
IF 2.7 4区 医学 Q2 Medicine Pub Date : 2022-09-10 eCollection Date: 2022-01-01 DOI: 10.1155/2022/4527844

Background: Vaccination is an effective public health measure to combat the SARS-CoV-2 pandemic. However, vaccine "hesitancy" has limited uptake in some, including inflammatory bowel disease (IBD) patients who may have unique concerns influencing uptake.

Aim: The aim of the study is to explore attitudes, concerns, and the influence of different sources of information on COVID-19 vaccine uptake in IBD patients.

Methods: Patients from a specialist IBD clinic at a tertiary hospital in Australia and a national IBD patient society were invited to complete an anonymous online survey regarding COVID-19 vaccination. Demographic characteristics, attitudes towards vaccination, and trust in sources of information were explored. Logistic regression was used to identify variables associated with vaccine uptake.

Results: Of 441 respondents, 93% of respondents had received at least 1 dose of COVID-19 vaccination. Self-perceived risk of being more unwell with COVID-19 infection due to IBD (AOR 5.25, 95% CI 1.96-14.04, p < 0.001) was positively associated with vaccine uptake. Concerns regarding the safety of vaccination in pregnancy (OR 0.22, 95% CI 0.08-0.65, p=0.006) and of causing an IBD flare (OR 0.28, 95% CI 0.10-0.77, p=0.01) were negatively associated with vaccine uptake. In total, 282 (73.7%) responders ranked healthcare workers the most trusted source to obtain information surrounding vaccination.

Conclusion: Vaccine hesitancy in IBD patients is low. Concerns about the safety of vaccination in pregnancy and in causing an IBD flare are both associated with vaccine hesitancy. Healthcare providers play a key role in proactively addressing these misconceptions particularly in the context of emerging virus variants and the availability of boosters.

背景:疫苗接种是抗击SARS-CoV-2大流行的有效公共卫生措施。然而,疫苗“犹豫”限制了一些人的吸收,包括炎症性肠病(IBD)患者,他们可能有影响吸收的独特因素。目的:本研究旨在探讨不同信息来源对IBD患者COVID-19疫苗接种的态度、关注和影响。方法:邀请来自澳大利亚某三级医院IBD专科诊所和国家IBD患者协会的患者完成关于COVID-19疫苗接种的匿名在线调查。探讨了人口统计学特征、对疫苗接种的态度以及对信息来源的信任。Logistic回归用于确定与疫苗摄取相关的变量。结果:在441名受访者中,93%的受访者至少接种了1剂COVID-19疫苗。因IBD感染COVID-19而感到更不适的自我感知风险(AOR 5.25, 95% CI 1.96-14.04, p < 0.001)与疫苗接种呈正相关。对妊娠期疫苗接种安全性的担忧(OR 0.22, 95% CI 0.08-0.65, p=0.006)和引起IBD爆发的担忧(OR 0.28, 95% CI 0.10-0.77, p=0.01)与疫苗接种呈负相关。总共有282名应答者(73.7%)将卫生保健工作者列为获得疫苗接种相关信息的最可信来源。结论:IBD患者的疫苗犹豫率较低。对妊娠期疫苗接种安全性和引起IBD爆发的担忧都与疫苗犹豫有关。医疗保健提供者在主动解决这些误解方面发挥着关键作用,特别是在新出现的病毒变体和增强剂可用性的背景下。
