Therapeutic efficacy of pretreatment with compound Acidophilus lactob-acillus tablets followed by quadruple therapy in gastric ulcer patients with Helicobacter pylori infection

AIM

To evaluate the efficacy of pretreatment with compound Acidophilus lactobacillus tablets followed by quadruple therapy in gastric ulcer patients with Helicobacter pylori (H. pylori) infection.

METHODS

One hundred and eighty patients with gastric ulcer associated with H. pylori infection treated at Department of Gastroenterology, Lishui City People's Hospital, from June 2015 to December 2017 were selected. All patients were diagnosed by gastroscopy and carbon-14 breath test positive. The patients were randomly divided into three groups: A, B, and C (60 cases each). All groups received pantoprazole 40 mg, amoxicillin 1.0 g, clarithromycin 500 mg, colloidal bismuth capsules 200 mg twice a day for 2 wk, followed by treatment with pantoprazole 20 mg once a day for 6 wk. Group B was additionally given compound Lactobacillus acidophilus tablets three times a day for the initial 2 wk. Group C was given compound Lactobacillus acidophilus tablets three times a day for 2 wk before quadruple therapy. The effective rate for ulcer, eradication rate of H. pylori, and the incidence of adverse reactions at 2 mo after treatment were compared among the three groups.

RESULTS

The effective rates for ulcer in groups A, B, and C were 73.3%, 88.3%, and 93.3%, respectively; the effective rates in groups B and C were significantly higher than that of group A (P < 0.05). The eradication rates of H. pylori in groups A, B, and C were 65.00%, 80.00%, and 91.67%, respectively; the eradication rate was significantly higher in groups B and C than in group A (P < 0.05), and in group C than in group B (P < 0.05). The incidence rates of adverse reactions in groups A, B, and C were 16.67%, 8.33%, and 6.67%, respectively; the incidence rates in groups B and C were significantly lower than that of group A (P < 0.05), although there was no significant difference between groups B and C (P > 0.05).

CONCLUSION

Pretreatment with compound Acidophilus lactobacillus tablets for 2 wk followed by quadruple therapy in gastric ulcer patients with H. pylori infection can effectively improve the eradication rate of H. pylori and reduce adverse drug reactions.
