Comparing the Efficacy of Concomitant Therapy with Sequential Therapy as the First-Line Therapy of Helicobacter pylori Eradication

Impact of Helicobacter pylori Eradication on Surgical Treatment of Peptic Ulcer Disease: Systematic Review

Peptic ulcer disease (PUD) poses a significant global healthcare challenge, with an intricate interplay between stomach acid-pepsin levels and mucosal protective mechanisms. The emergence of Helicobacter pylori (H. pylori) as a major etiological factor revolutionized the therapeutic landscape, highlighting the importance of bacterial eradication in PUD management. Surgical intervention remains vital, particularly in cases of perforated peptic ulcers, despite a shift towards conservative approaches. Understanding the impact of H. pylori eradication on surgical outcomes is crucial for optimizing PUD management. This systematic review was conducted to assess how H. pylori eradication treatment impacts surgical results in patients with PUD. The criteria for inclusion involved research studies on individuals aged 18 years and older with a diagnosis of PUD that necessitated surgical treatment. Important results comprised eradication rates, complications after surgery, recurrence rates, and overall outcomes for patients. Two researchers independently screened and extracted data from electronic databases using a thorough search strategy. The evaluation of quality employed standardized instruments for randomized controlled trials and cohort studies. Nine research projects met the requirements for inclusion, offering information on the effectiveness of H. pylori elimination treatment on surgical results. Different rates of eradication were noted, with a notable number of patients experiencing postoperative complications. Recurrence of ulcers was a concern, despite treatment, emphasizing the complexity of PUD management. Studies have shown that eradication therapy is effective in certain patient groups, like young men with perforated peptic ulcers. Still, there are obstacles, especially for patients who test negative for H. pylori and experience recurring ulcers. The integration of H. pylori eradication with surgical intervention represents a holistic approach to PUD management. Although eradication therapy has the potential to enhance surgical results, difficulties remain, requiring personalized treatment approaches that consider patients' unique characteristics and the cause of the disease. This research adds to the growing knowledge of PUD treatment, stressing the importance of proper management.

Comparative efficacy and safety of high-dose dual therapy, bismuth-based quadruple therapy and non-bismuth quadruple therapies for Helicobacter pylori infection: a network meta-analysis

Helicobacter pylori (H. pylori) infection is associated with the development of multiple diseases. The eradication rate of H. pylori has gradually decreased, suggesting the need to discover more effective therapies. This study aimed to compare the effectiveness of first-line treatments including high-dose dual therapy (HDDT), bismuth-based quadruple therapy (BQT), sequential therapy (ST), concomitant therapy (CT) and hybrid therapy (HT) by network meta-analysis (NMA). A comprehensive search on PubMed, Embase, Cochrane Library and Web of Science, was performed from their inception to 1 September 2019. A network analysis of randomized controlled trials (RCTs) comparing first-line therapies were carried out using Stata 14.0 and Revman 5.2. Moreover, a sensitivity analysis was conducted by omitting non-Asian studies. Finally, 41 RCTs with 14 119 patients were included. The NMA showed that, in terms of eradication rate, ST for 10 days (ST-10) was significantly lower than CT for 10 or 14 days (CT ≥ 10). Sensitivity analysis among the Asian population showed that ST-10 denoted the lowest effectiveness among the interventions. The ranking results based on probability showed that HDDT ranked first for the eradication rate. As for adverse events, HDDT was significantly less than BQT and CT regardless of duration, while BQT for 14 days represented higher adverse events than ST, HT and CT ≥ 10. HDDT ranked first among the therapies. In conclusion, HDDT for 14 days appeared to be the most optimal first-line therapy for H. pylori among the Asian population with comparable efficacy and compliance but causing fewer adverse events.

Clinical Outcomes of Standard Triple Therapy Plus Probiotics or Concomitant Therapy for Helicobacter pylori Infection

Background/Aims

The efficacy of standard triple therapy (STT) in treating Helicobacter pylori infection has decreased. Many investigators have attempted to increase the eradication rate. We investigated the outcomes of concomitant therapy (CT) and STT combined with probiotics (STP) as a first-line treatment for H. pylori infection.

Methods

We reviewed the medical records of 361 patients who received either STP (n=286) or CT (n=75). The STP group received STT combined with a probiotic preparation for 1 week. The CT group received STT and metronidazole for 1 week.

Results

The intention-to-treat and per-protocol eradication rates were 83.6% (95% confidence interval [CI], 79.0 to 87.7) and 87.1% (95% CI, 81.2 to 89.7) in the STP group and 86.7% (95% CI, 78.7 to 93.3) and 91.4% (95% CI, 83.6 to 97.1) in the CT group (p=0.512 and p=0.324), respectively. The frequency of adverse effects was higher in the CT group (28.2%) than in the STP group (12.8%) (p=0.002).

Conclusions

STP and CT are encouragingly efficacious as first-line treatments for H. pylori infection. Therefore, adding probiotics to STT may be a feasible option to avoid side effects.

Optimal First-Line Treatment for Helicobacter pylori Infection: Recent Strategies

A new treatment strategy is needed, as the efficacy of triple therapy containing clarithromycin—the current standard treatment for Helicobacter pylori infection—is declining. Increasing antibiotic resistance of H. pylori is the most significant factor contributing to eradication failure. Thus, selecting the most appropriate regimen depending on resistance is optimal, but identifying resistance to specific antibiotics is clinically challenging. In a region suspected to have high clarithromycin resistance, bismuth quadruple therapy and so-called nonbismuth quadruple therapies (sequential, concomitant, and sequential-concomitant hybrid) are some first-line regimen options. However, more research is needed regarding appropriate second-line treatments after first-line treatment failure. Tailored therapy, which is based on antibiotic sensitivity testing, would be optimal but has several limitations for clinical use, and an alternative technique is required. A novel potassium-competitive acid blocker-based eradication regimen could be a valuable eradication option in the near future.

Treatment of Helicobacter pylori infection 2016

Many interesting articles have been published from different parts of the world over the last year assessing various issues around Helicobacter pylori eradication therapy. This article will address the published literature over the last year pertaining to the topic of treatment of H. pylori infection. The main themes that emerge are assessing the efficacy of standard triple therapy, as well as exploring new first-line treatments, mainly optimized nonbismuth-containing and bismuth-containing quadruple therapies with some promising data also emerging on dual therapy. There was also considerable progress in investigating antibiotic resistance rates with much more data emerging from varied parts of the world compared to recent years. Advances in the use of adjunctive therapies, especially probiotic therapies have also been made. Undoubtedly, the eradication of H. pylori remains a worthwhile goal to alleviate the burden of diseases caused by the complications of this infection, including dyspepsia, peptic ulcer disease, and gastric cancer.

Ten-day empirical sequential or concomitant therapy is more effective than triple therapy for Helicobacter pylori eradication: A multicenter, prospective study

BACKGROUND

The resistance of Helicobacter pylori to antibiotics has increased the need for new empirical, first-line treatments. However, the efficacy of sequential therapy (ST) and concomitant therapy (CT) compared with triple therapy (TT) has not been adequately evaluated.

AIM

In this study, we evaluated the efficacy of these empirical three regimens.

METHODS

The 517 patients enrolled in the study were prospectively randomized to receive 10 days of TT (n=171), ST (n=170), and CT (n=176) at 5 university-affiliated hospitals from May 2013 to March 2015. The post-treatment H. pylori status was determined using the (13)C-urea breath test.

RESULTS

The baseline characteristics were similar among the three groups. The intention-to-treat eradication rates were 62.6%, 70.6%, and 77.8% in the TT, ST, and CT groups, respectively (p<0.01). The corresponding per-protocol eradication rates were 82.8%, 89.5%, and 94.4%, respectively (p<0.01). There were no significant differences in the compliance, side effects, and follow-up loss rates.

CONCLUSION

A higher eradication rate was achieved with empirical 10-day ST, and CT than with the TT regimen, with similar rates of compliance and treatment side effects.
