Helicobacter pylori (HP) infection is closely associated with the occurrence of such common upper gastrointestinal diseases as chronic gastritis, peptic ulcer and gastric cancer. However, even with the currently most effective treatment regimens, approximately 10% to 20% of patients still fail to obtain eradication of the infection and remain HP positive. So the eradication of HP infection remains one of the major challenges in the medical field. This article aims to introduce the evidence for the choice of the second-line regimens after the failure of the first therapy. And the evidence includes the quadruple therapy proposed by the Maastricht III Consensus and the triple regimens with different antibiotics in all kinds of randomized clinical trials.
Objective To make an individualized treatment plan for one first-visit gastro-esophageal reflux disease patient via evidence-based medicine methods. Methods The condition of the patient was evaluated comprehensively, then clinical problems were put forward according to PICO principle, and high-quality evidence was collected from The Cochrane Library (1990 to 2010), PubMed (1990 to 2010), and EMbase (1990 to 2010). The treatment plan was designed based on the evaluation of evidence, doctor’s experience, and patient’s preferences. Results A total of 17 RCTs and 10 meta-analyses/ systematic reviews were included. The evidence showed that the therapeutic effect of PPI was better than that of H2RA, and meanwhile prokinetic drugs should be used. When PPI needed to be use for a long time, HP eradication operation was required for the combination of HP inflammation. Laparoscopic fundoplication surgery was a better choice if the operation was required. Based on the above evidence combined with the patient’s preferences, the combination of general treatment, esomeprazole and cisaPride were adopted to treat. Meanwhile, anti-HP medicine was used to control the HP inflammation caused by the long-term maintenance therapy. The gastro-esophageal reflux symptoms were remarkably relieved six months after the treatment. Conclusion PPI plus prokinetic drugs, combined with HP eradication of gastroesophageal reflux surgery, can improve the clinical outcomes and patient’s quality of life. However, long-term prognostic benefits need to be confirmed by further follow-up.
ObjectiveTo systematically review the association between Helicobacter pylori (HP) infection and Parkinson's disease (PD). MethodsPubMed, EMbase, The Cochrane Library, CNKI, VIP and WanFang Data databases were electronically searched to collect case-control studies on the association between HP and PD from January 2000 to July 2021. Two reviewers independently screened literature, extracted data, and assessed the risk of bias of included studies. Meta-analysis was then performed using RevMan 5.3 software. ResultsA total of 16 case-control studies involving 2 790 subjects were included. The results of meta-analysis showed that the HP infection rate was higher in PD patients than that in healthy patients (OR=1.87, 95%CI 1.38 to 2.54, P<0.000 1). The results of subgroup analysis showed that the infection rate of HP in PD group in Asia and Africa region was significantly higher than that in control group, but not in Europe region. Breath tests and other detection methods were used to detect HP infection, and the HP infection rate in PD group was significantly higher than that in the healthy control group. However, there was no significant difference in HP infection between the two groups by ELISA. UPDRS Ⅲ score of PD patients with HP infection was significantly higher than that of PD patients without HP infection. ConclusionsCurrent evidence shows that PD patients have a higher HP infection rate than the normal population, and the rates are affected by regions and HP detection methods. In addition, HP infection can aggravate the motor symptoms and motor complications of PD patients. Due to limited quality and quantity of included studies, more high-quality studies are required to verify the above conclusions.
