Comparative Efficacy of Antidepressants for Symptoms Remission of Gastroesophageal Reflux: A Bayesian Network Meta-analysis of Randomized Controlled Trials.

BACKGROUND: The present study aimed to compare and evaluate the efficacy of antidepressants in remission of esophageal reflux symptoms. METHODS: A comprehensive literature review was performed including sources published on MEDLINE, EMBASE, the Cochrane Central Registry of Controlled Trials (Cochrane), Web of Science, China National Knowledge Infrastructure Database (CNKI), Chinese VIP Information Databases (VIP), Chinese Biology Medicine disc (CBM), and Wan-Fang databases for randomized controlled trials, published up to and including March 31, 2020. We analyzed relevant randomized, placebo-controlled trials reporting the effect of antidepressant therapy in relieving esophageal reflux symptoms ADDIS 1.16.8 was used to perform the network meta-analysis. Furthermore, we performed a split analysis to test inconsistency, and rank probability was complemented for comparison among antidepressants. RESULTS: A total of 10 randomized controlled trials (RCTs) examining the effects of antidepressants, selective 5-HT reabsorption inhibitor (SSRI), 5-HT 1A receptor agonist (5-HT1AA), tricyclic antidepressants (TCAs), and the complex of flupentixol-melitracen (FM) were included. Flupentixol-melitracen and SSRIs exhibited a significantly higher rate of remission than placebo. However, there was no statistically significant difference among different antidepressants compared. Rank probability showed that FM exhibited the highest probability of rank 1 compared with other antidepressants and placebo. CONCLUSION: This network meta-analysis of RCTs supported the use of FM and SSRIs as a potentially effective regimen for symptom remission of gastroesophageal reflux. Furthermore, according to our analysis, FM represents the most efficient antidepressant with highest probability of symptom remission.

Gastric Juice-Based Genotypic Methods for Diagnosis of Helicobacter pylori Infection and Antibiotic Resistance Testing: A Systematic Review and Meta-analysis.

OBJECTIVE: To evaluate the diagnostic efficacy of gastric juice-based genotypic methods for Helicobacter pylori detection and antibiotic resistance testing. METHODS: We used electronic databases including Medline, Embase, Web of Science and the Cochrane Central Register of Controlled Trial for literature survey using keywords such as "gastric juice", "Helicobacter pylori" and their synonyms. The quality of the studies was assessed using QUADAS-2. Summary performance measures (sensitivity, specificity, positive predictive values, negative predictive values, diagnostic odds ratio, and area under the summary receiver operating characteristic curve) and HSROC curves were produced. In addition, fagan plots were applied to illustrate the relationship among the prior test probability, PLR/NLR, and posterior test probability. RESULTS: Our study cohort comprised eight studies with 1235 participants (617 participants of H. pylori infection and 618 participants of non-H. pylori infection). Pooled sensitivity and specificity with a corresponding 95% confidence interval (CI) of gastric juice-based genotypic methods reflected values of 94% (95%CI, 86% - 98%) and 98% (95%CI, 85% - 100%), respectively. The global sensitivity and specificity of clarithromycin resistance were 92% (95%CI, 85% - 96%) and 90% (95%CI, 80% - 95%), respectively. CONCLUSION: Gastric juice-based genotypic methods can be used for diagnostic prediction of H. pylori infection as well as clarithromycin resistance testing.
