Objective:
Helicobacter pylori (HP) is the world's most common infectious agent. Despite conventional therapy consisting of proton pump inhibitor (PPI), amoxicillin (AMO) and clarithromycin (CLA), approximately half of the patients remain infected. We compared the PPI-based triple therapy with quadruple treatment (BPMT) including bismuth citrate (BS), PPI, metronidazole (MET) and tetracycline (TET).
Material And Methods:
Forty-three patients who used triple therapy (LAC) consisting of lansoprazole (L), AMO and CLA and 42 patients who used quadruple therapy (BPMT) for 14 days between May 2008 and November 2013 were included in the study. The LAC group included patients who received 30 mg L 2×1, 1000 mg AMO 2×1, and 500 mg CLA 2×1 for 14 days, whereas the BPMT group was designed from patients who received 600 mg BS 2×1, 40 mg omeprazole (O) 2×1 or 30 mg L 2×1, 500 mg MET 3×1 and 500 mg TET 4×1.
Results:
Demographic characteristics and endoscopic findings were similar in both groups. The eradication rate was 53.4% in the LAC group and 78.5% in the BPMT group (p<0.05). Compliance problems and side effects were significantly higher in the BPMT group as compared to the LAC group (p<0.05).
Conclusion:
Due to high antibiotic resistance in Turkey, the efficacy of LAC treatment has reduced. The BPMT protocol should be kept in mind in the first line of treatment, since it provides a higher eradication rate.
Insights
Quadruple therapy (BPMT) including bismuth citrate, metronidazole, and tetracycline shows higher Helicobacter pylori eradication rates than standard triple therapy. Despite increased side effects, BPMT is recommended for first-line treatment due to antibiotic resistance.
Area of Science:
- Gastroenterology
- Infectious Diseases
- Microbiology
Background:
- Helicobacter pylori (HP) is a prevalent global infection.
- Conventional triple therapy (lansoprazole, amoxicillin, clarithromycin) has declining efficacy.
- High antibiotic resistance necessitates alternative treatment strategies.
Purpose of the Study:
- To compare the efficacy of PPI-based triple therapy (LAC) with quadruple therapy (BPMT) for HP eradication.
- To evaluate treatment outcomes in patients with HP infection.
Main Methods:
- A comparative study involving 43 patients on LAC and 42 patients on BPMT for 14 days.
- LAC: lansoprazole, amoxicillin, clarithromycin.
- BPMT: bismuth citrate, omeprazole/lansoprazole, metronidazole, tetracycline.
Main Results:
- HP eradication rate was 53.4% for LAC and 78.5% for BPMT (p<0.05).
- Demographics and endoscopic findings were similar between groups.
- Higher compliance issues and side effects were observed in the BPMT group (p<0.05).
Conclusions:
- Standard LAC treatment efficacy is reduced in regions with high antibiotic resistance, such as Turkey.
- BPMT offers a significantly higher eradication rate for HP.
- BPMT should be considered as a first-line treatment option for HP infections.
