RESUMO

BACKGROUND: There are concerns regarding the effect of biological agents on SARS-CoV-2 vaccination in patients with inflammatory bowel disease (IBD). A systematic review and meta-analysis was performed about the serological responses, breakthrough infections and clinical relapse of IBD patients treated with biological agents following SARS-CoV-2 vaccination. METHODS: Electronic databases were searched to identify relevant studies. Primary outcomes were the pooled seroconversion rates, breakthrough infection rates and clinical relapse rates after SARS-CoV-2 vaccination in IBD patients treated with biological agents. Secondary outcomes were the comparison of seroconversion rates, breakthrough infection rates and clinical relapse rates in IBD patients treated with biological agents and control cohort after SARS-CoV-2 vaccination. RESULTS: Thirty-five studies were included in this meta-analysis. A high percentage of seroconversion (96.6%, 99% and 99.2%) was achieved in IBD patients treated with anti-TNF-α therapy, vedolizumab and ustekinumab after SARS-CoV-2 vaccination, respectively. The pooled breakthrough infection rate was 2.5% and 3.9% in IBD patients treated with anti-TNF-α therapy and vedolizumab, respectively. The breakthrough infection rate in IBD patients treated with anti-TNF-α therapy was significantly lower than control cohort (RR 0.178, 95% CI 0.084-0.378). The pooled clinical relapse rate in IBD patients treated with anti-TNF-α therapy, vedolizumab and ustekinumab was 6.9%, 5.4% and 5.3%, respectively. CONCLUSION: The overall seroconversion rate after SARS-CoV-2 vaccination in IBD patients treated with biological agents is high. The overall breakthrough infection rate and clinical relapse rate in IBD patients treated with biological agents were low.

RESUMO

BACKGROUND: There are concerns regarding anti-TNF-induced lupus (ATIL) in patients with inflammatory bowel disease (IBD). We performed a systematic review and meta-analysis about the incidence, the clinical characteristics and serological characteristics of ATIL secondary to anti-TNF agents in IBD patients. METHODS: Electronic databases were searched to identify relevant studies. Primary outcomes were the pooled ATIL incidence rates in IBD patients treated with anti-TNF agents. Secondary outcomes were the pooled clinical symptoms incidence rates, autoantibodies incidence rates and clinical resolution rates in IBD patients treated with anti-TNF agents. RESULTS: Ten studies were included in this meta-analysis. The pooled ATIL incidence rate in IBD patients treated with anti-TNF-α agents was 2.5%. The pooled ATIL incidence rate in UC and CD patients treated with anti-TNF-α agents was 1.5% and 1.8%, respectively. The pooled ATIL incidence rate in IBD patients treated with IFX and ADA was 4.5% and 0.2%, respectively. The pooled arthritis, mucocutaneous symptom, myalgia and fatigue incidence rate in IBD patients treated with anti-TNF-α agents was 87.2%, 29.4%, 23.9% and 41.8%, respectively. The pooled ANA rate in IBD patients treated with anti-TNF-α agents was 97.3%. The pooled anti-dsDNA antibody rate in IBD patients treated with anti-TNF-α agents was 73.9%. CONCLUSION: ATIL has a low prevalence in IBD patients treated with anti-TNF agents. ATIL occurs more frequently in CD patients than in UC patients. Arthritis, fatigue and mucocutaneous lesions were found to be common symptoms of ATIL. Patients with ATIL were more likely to develop ANA and anti-dsDNA.

RESUMO

An important goal of the Hepatitis E virus (HEV) vaccine is to prevent adverse pregnancy outcomes caused by different HEV genotypes during pregnancy, but studies directly evaluating maternal vaccination for HEV are lacking. Here we report maternal vaccination using HEV 239 vaccine in a pregnant rabbit model. Two dose of accelerated vaccination schedule (0, 7 days) induced high titers of anti-HEV protective antibodies in a short period of time in pregnant rabbits, which could protect the pregnant rabbits from HEV infection and adverse pregnancy outcomes. In addition, the immunized rabbits transfer maternal antibodies to pups through the placenta and breast milk, which protect neonates against HEV infection. Our results suggest that, besides vaccinating nonpregnant individuals, HEV 239 vaccine may also be discreetly considered for maternal vaccination.

RESUMO

Crohn's disease (CD) is a chronic inflammatory disorder of the gastrointestinal tract that is commonly known to affect the ileum and colon. Aseptic abscess (AA) has been pathologically described as sterile abscess with a predominance of polymorphonuclear leucocyte infiltrates, and is considered a rare extraintestinal manifestation of CD. AA presents a great challenge to physicians in determining if it is an extraintestinal manifestation of CD or an actual infection with pathogenic microorganisms. There is a strong association between CD and psoriasis. But the coexistence of AA and psoriasis in CD was unusual. Ustekinumab, as an IL 12/23 inhibitor, is the only treatment with a similar mechanism currently available for both CD and psoriasis. We report a case of successful use of ustekinumab to treat a CD patient with hepatic AA and psoriasis.

RESUMO

BACKGROUND: The KODEX-EPD system is a novel, dielectric three-dimensional mapping system. We aim to illustrate the feasibility, safety, and outcomes of ablation using the KODEX-EPD system. METHODS: A total of 272 patients with supraventricular arrhythmias were enrolled and underwent catheter ablation using the KODEX-EPD system from October 2020 to July 2021. The feasibility, safety, and ablation outcomes were analyzed. RESULTS: Of the enrolled patients, 15 (5.4%) had atrial tachycardia (AT), 88 (31.4%) had atrioventricular reentrant tachycardia (AVRT), 141 (50.4%) had atrioventricular nodal reentrant tachycardia (AVNRT), 34 (12.1%) had atrial fibrillation (AF), and 9 (3.2%) had atrial flutter (AFL). All AF patients included were first-do-pulmonary vein isolation (PVI); there were 26 paroxysmal AF and 8 persistent AF. All patients achieved immediate success of ablation. The mean follow-up duration was 11.8 ± 2.4 months. One patient (1.1%) in the AVRT subgroup and two patients (1.4%) in the AVNRT subgroup experienced recurrence. When considering a three-month blanking time, the estimated freedom of AF at one-year post-ablation with and without AADs was 75.7% and 70.4%, respectively. The Kaplan-Meier analysis showed no significant difference in the overall AF recurrence (log-rank; P = 0.931) or AAD-free AF recurrence (log-rank; P = 0.841) between RFCA and cryoablation. One patient had mild pulmonary embolism. None of the patients died or had a cerebrovascular event in the periprocedural period. CONCLUSIONS: This retrospective, two-center study demonstrated that catheter ablation of supraventricular arrhythmias using the KODEX-EPD system is feasible, safe, and effective. Trial registration Retrospectively registered.

RESUMO

BACKGROUND: Inflammatory bowel disease is a chronic recurrent disease, and the treatment goals of inflammatory bowel disease are mainly based on doctors' perspective, but there are some differences between the doctor's perspective and the patient's perspective. The aim of this study is to understand the treatment goals and the related factors from the patients' perspective during the coronavirus disease 2019 pandemic. METHODS: A total of 212 participants were recruited to fill out the questionnaires including clinical characteristics and treatment goals. Eleven treatment goals were measured by a Short-Form 34 questionnaire. Univariate and multivariate regression analyses were used to explore the related factors about these treatment goals. RESULTS: A total of 212 inflammatory bowel disease patients were enrolled in this study. The most concerned treatment goal was the improvement of quality of life (mean score was 8.54), while mean score of ulcerative colitis patients and Crohn's disease patients was 9.10 and 8.45, respectively. We had also found some related factors such as the type of disease, the course of disease, the frequency of hematochezia, and defecation. CONCLUSION: Our survey showed that inflammatory bowel disease patients pay more attention to the improvement of quality of life and few drugs during the coronavirus disease 2019 pandemic. There are some related factors such as the type of disease, the course of dis- ease, the frequency of hematochezia, and defecation. Our results help clinicians understand the patients' treatment goals, which can contribute to better management of inflammatory bowel disease patients.

RESUMO

Congenital bilateral absence of the vas deferens (CBAVD) is observed in 1%-2% of males presenting with infertility and is clearly associated with cystic fibrosis transmembrane conductance regulator (CFTR) mutations. CFTR is one of the most well-known genes related to male fertility. The frequency of CFTR mutations or impaired CFTR expression is increased in men with nonobstructive azoospermia (NOA). CFTR mutations are highly polymorphic and have established ethnic specificity. Compared with F508Del in Caucasians, the p.G970D mutation is reported to be the most frequent CFTR mutation in Chinese patients with cystic fibrosis. However, whether p.G970D participates in male infertility remains unknown. Herein, a loss-of-function CFTR p.G970D missense mutation was identified in a patient with CBAVD and NOA. Subsequent retrospective analysis of 122 Chinese patients with CBAVD showed that the mutation is a common pathogenic mutation (4.1%, 5/122), excluding polymorphic sites. Furthermore, we generated model cell lines derived from mouse testes harboring the homozygous Cftr p.G965D mutation equivalent to the CFTR variant in patients. The Cftr p.G965D mutation may be lethal in spermatogonial stem cells and spermatogonia and affect the proliferation of spermatocytes and Sertoli cells. In spermatocyte GC-2(spd)ts (GC2) Cftr p.G965D cells, RNA splicing variants were detected and CFTR expression decreased, which may contribute to the phenotypes associated with impaired spermatogenesis. Thus, this study indicated that the CFTR p.G970D missense mutation might be a pathogenic mutation for CBAVD in Chinese males and associated with impaired spermatogenesis by affecting the proliferation of germ cells.

RESUMO

A 56-year-old man with half of year history of UC was admitted to our hospital due to abdominal pain, diarrhea, and hematochezia (more than ten times per day) for two weeks. He had had homosexual intercourse with many men. Subsequent laboratory findings revealed that there was a significant increase in elevated white blood cells (WBC, 11.77x109/L), C-Reactive Protein (CRP, 83.7 mg/L), tumor necrosis factor-alpha (TNF-ɑ, 6.83 pg/ml), interleukin-2 (IL-2, 75.78 pg/ml), IL-6 (124.68 pg/ml), IL-10 (58.24 pg/ml) and IL-17 (128.76 pg/ml), and fecal calprotectin (FC >1800 µg/g). Albumin (ALB, 22.5 g/L) and Hemoglobin (Hb, 98 g/L) were significantly decreased. Amoeba was identified in the stool. The abdominal contrast-enhanced Computed Tomography (CT) showed that there was thickened intestinal wall in the sigmoid colon and rectum. Colonoscopy and intestinal histopathology suggested active severe UC (E2) and Entamoeba Histolytica (trophozoites) in the necrotic tissue (Figure 1). The result of enzyme immunoassay (EIA) screening for HIV was positive. The HIV viral load was 7.85x109 copies/mL, and the CD4+ cell count was 43/µL.

RESUMO

BACKGROUND & AIMS: The Global Leadership Initiative on Malnutrition (GLIM) has recently been proposed as a consensus criterion for identifying malnutrition. However, data on the application of GLIM criteria in patients with inflammatory bowel disease (IBD) are limited. Therefore, this study aimed to explore the validity of this neoteric criterion for identifying malnutrition and investigate the association between malnutrition and quality of life (QoL) in patients with IBD. METHODS: This multicenter, prospective, observational study assessed hospitalized patients with IBD at four general hospitals. Nutritional status was evaluated using criteria from the World Health Organization (WHO) related body mass index (BMI) cut-off value, Subjective Global Assessment (SGA), European Society for Clinical Nutrition and Metabolism (ESPEN) criteria of malnutrition in 2015, and GLIM criteria. Kappa (K) values were calculated to determine interrater validity and consistency among different prevalence of malnutrition. Patients' QoL was assessed by the Inflammatory Bowel Disease Questionnaire (IBDQ). RESULTS: A total of 238 hospitalized patients with IBD were enrolled, with a mean age of 38.5 ± 14.0 years, 68.5% of them were male, and 177 with Crohn's disease (CD). Among all patients, 39.5% were underweight (BMI < 18.5 kg/m2), and the prevalence of malnutrition was 66.0%, 47.5%, and 60.1% according to SGA, ESPEN, and GLIM criteria, respectively. Moreover, the prevalence of malnutrition was significantly higher among patients with CD than those with ulcerative colitis (UC), according to GLIM criteria (69.5% vs. 32.8%, p < 0.001). The GLIM criteria showed a substantial concordance with ESPEN criteria (K = 0.67, 95% confidence interval [CI] 0.58-0.76, p < 0.001), and a fair concordance with the SGA (K = 0.57, 95% CI 0.46-0.68, p < 0.001) and WHO criteria (K = 0.52, 95% CI 0.43-0.62, p < 0.001). An impairment in the nutritional status was accompanied by a progressive reduction in the patients' QoL. CONCLUSIONS: The prevalence of malnutrition is high in patients with IBD. The GLIM criteria may be an appropriate and effective tool to identify malnutrition in the IBD populations due to its substantial concordance with ESPEN and a fair concordance with SGA and WHO-related BMI. GLIM-defined malnutrition showed an enormous adverse impact on patients' QoL.

RESUMO

Hepatocellular carcinoma (HCC) seriously endangers humans. In traditional Chinese medicine, Marsdenia tenacissima (MTE) has anti-inflammatory, antiasthmatic, antihypertensive, and anticancer effects. This study reveals the antiproliferative effect of MTE on the HCC cells in vitro and provides a theoretical basis for the development and clinical application of anti-HCC agents. Methods. MHCC-97H and HepG2 cells were cultured in vitro and exposed to various concentrations and durations of MTE, and an MTT assay was used to detect the effects of MTE on cell proliferation. Transmission electron microscopy revealed the morphological changes in the two cell lines after MTE stimulation. The MTE effects on the apoptosis and cell cycle distribution of the cell lines were detected by flow cytometry. Western blotting and qRT-PCR were used to detect target gene expression at the protein and mRNA levels, respectively. Results. MTE reduced the viability of the MHCC-97H and HepG2 cells in a dose- and time-dependent manners (P < 0.05). Autophagic vesicles and apoptotic bodies were found in the MHCC-97H and HepG2 cells after MTE incubation, and the Annexin V-PI assay showed that the apoptotic rates of the cell lines increased with increasing MTE concentration (P < 0.05). Autophagy inducer rapamycin promoted the MTE-induced apoptotic rates of the cell lines, whereas autophagy inhibitor chloroquine inhibited the apoptotic rates. More cells in the S phase were found in the two cell lines after MTE treatment (P < 0.05). After MTE incubation, MIF, CD47, and beclin-1 protein levels significantly increased. Furthermore, in the MTE group, Akt, mTOR, and caspase3 expressions decreased; however, LC 3 expression increased, which was significantly different from the control group (P < 0.05). Conclusions. MTE inhibited proliferation and induced autophagy, apoptosis, and S phase cell cycle arrest in the MHCC-97H and HepG2 cells. These effects might be related to the activation of MIF and mTOR signaling inhibition.

RESUMO

BACKGROUND: Numerous variants of uncertain significance (VUSs) have been identified by whole exome sequencing in clinical practice. However, VUSs are not currently considered medically actionable. OBJECTIVE: To assess the splicing patterns of 49 VUSs in 48 families identified clinically to improve genetic counselling and family planning. METHODS: Forty-nine participants with 49 VUSs were recruited from the Reproductive and Genetic Hospital of CITIC-Xiangya. Bioinformatic analysis was performed to preliminarily predict the splicing effects of these VUSs. RT-PCR and minigene analysis were used to assess the splicing patterns of the VUSs. According to the results obtained, couples opted for different methods of reproductive interventions to conceive a child, including prenatal diagnosis and preimplantation genetic testing (PGT). RESULTS: Eleven variants were found to alter pre-mRNA splicing and one variant caused nonsense-mediated mRNA decay, which resulted in the reclassification of these VUSs as likely pathogenic. One couple chose to undergo in vitro fertilisation with PGT treatment; a healthy embryo was transferred and the pregnancy is ongoing. Three couples opted for natural pregnancy with prenatal diagnosis. One couple terminated the pregnancy because the fetus was affected by short-rib thoracic dysplasia and harboured the related variant. The infants of the other two couples were born and were healthy at their last recorded follow-up. CONCLUSION: RNA splicing analysis is an important method to assess the impact of sequence variants on splicing in clinical practice and can contribute to the reclassification of a significant proportion of VUSs. RNA splicing analysis should be considered for genetic disease diagnostics.

RESUMO

Fluorescent porous organic cage with good water solubility is of great interest but still challenging for its fluorescent sensing application. Poor water solubility and single signal of most previous probes are unfavorable for the monitoring of Au3+ generated from the potential dissociation of gold nanoparticles in environmental and biological samples. Here we report a water-soluble porous organic cage as a ratiometric fluorescent probe for Au3+ in aqueous solution. The prepared porous organic cage with good water solubility showed specific redox interaction with Au3+ in pH 5, leading to the change of dual emission at 420 and 484 nm. Based on the change of fluorescence ratio, a simple ratiometric sensing method for Au3+ from the dissociation of gold nanoparticles in aqueous solution was developed. The proposed method gave a calibration function of F484/F420 = 0.0370[Au3+] + 0.5689 (where F484/F420 is the intensity ratio of fluorescence at 484 nm to that at 420 nm; [Au3+] in µM) (R2 = 0.9975) in the concentration range of 1-60 µM, the limit of detection (3s) of 8 nM, and the relative standard deviation of 0.26% for 10 replicate detections of 50 µM Au3+. The recoveries of spiked Au3+ in domestic wastewater and human serum samples ranged from 94.66% to 105.61%.
