Trichuris suis ova therapy in inflammatory bowel disease: A meta-analysis.

ABSTRACT: In recent years, Trichuris suis ova (TSO) therapy in inflammatory bowel disease (IBD) has attracted much attention. However, efficacy and safety of TSO therapy are still not well described. The aim of the study was to perform a meta-analysis to assess the effectiveness of TSO therapy in IBD.PubMed, Embase, Web of Science, ClinicalTrials.gov, and Cochrane Library were searched from inception to August 2017. Only randomized, double-blind, placebo-controlled trials (RCTs) were included. The pooled estimate rates were performed by meta-analysis and reported according to the standard Cochrane guidelines and the PRISMA statement.In ulcerative colitis study (3 RCTs, n?=?74), the induced rates of clinical remission and clinical response were 10.8% (4/37) and 53.8% (21/39) in TSO group, while 6.7% (2/30) and 29.0% (9/31) in placebo group (all P?>?.26). Twenty-two (9/41) percent of patients in TSO group experienced at least 1 adverse event compared with 27.3% (9/33) of placebo [relative ratio (RR) 0.75, 95% confidence interval (95% CI) 0.17-3.27]. In Crohn disease study (3 RCTs, n?=?538), 40.7% (74/182) of patients in TSO group achieved clinical remission compared with 42.9% (90/210) of placebo (RR 0.95, 95% CI 0.75-1.20); 45.9% (141/307) of patients in TSO group entered clinical response compared with 45.1% (151/335) of placebo (RR 1.02, 95% CI 0.86-1.21). There were sparse data of adverse events reporting both TSO and placebo group (RR 1.00, 95% CI 0.88-1.13).TSO therapy showed no statistical benefit for IBD patients, so it suggested clinicians consider its value carefully before putting into clinical practice. Perhaps continued investigations of larger sample size are necessary due to the previous results with lack of power.

Project description:There is conflicting evidence concerning the effect of inflammatory bowel disease (IBD) on COVID-19 incidence and outcome. Hence, we aimed to evaluate the published evidence through a systematic review process and perform a meta-analysis to assess the association between IBD and COVID-19. A compressive literature search was performed in PubMed/Medline, Scopus, Embase, and Cochrane Library from inception to July 2021. A snowball search in Google, Google Scholar, Research Gate, and MedRxiv; and bibliographic research were also performed to identify any other relevant articles. Quantitative observational studies such as cohort, cross-sectional, and case-control studies that assessed the incidence, risk, and outcomes of COVID-19 among the adult IBD patients published in the English language, were considered for this review. The incidence and risk of COVID-19, COVID-19 hospitalization, the severity of COVID-19, and mortality were considered as the outcomes of interest. The Joanna Briggs Institute critical appraisal checklist was used for quality assessment. A subgroup and sensitivity analysis were performed to explore the heterogeneity and robustness of the results, respectively. A total of 86 studies out of 2828 non-duplicate records were considered for this meta-analysis. The studies were single or multicentric internationally from settings such as IBD centres, medical colleges, hospitals, or from the general public. Most of the studies were observed to be of good quality with an acceptable risk of bias. The pooled prevalence of COVID-19, COVID-19 hospitalization, severe COVID-19, and mortality in the IBD population were 6.10%, 10.63%, 40.43%, and 1.94%, respectively. IBD was not significantly (p > 0.05) associated with the risk of COVID-19, COVID-19 hospitalization, severe COVID-19, and mortality. In contrast, ulcerative colitis was significantly associated with a higher risk of COVID-19 (OR 1.37; p = 0.01), COVID-19 hospitalization (OR 1.28; p < 0.00001), and severe COVID-19 (OR 2.45; p < 0.0007). Crohn's disease was significantly associated with a lesser risk of severe COVID-19 (OR 0.48; p = 0.02). Type of IBD was a potential factor that might have contributed to the higher level of heterogeneity. There was a significant association between ulcerative colitis and increased risk of COVID-19, COVID-19 hospitalization, and severe COVID-19 infection. This association was not observed in patients with Crohns' disease or in those diagnosed non-specifically as IBD.
