Abstract:Objective To investigate the effect of Jinghua Weikang capsules combined with quadruple therapy on Helicobacter pylori infection. Methods A total of 684 cases of chronic gastritis with Helicobacter pylori infection were randomly divided into a group A, a group B, a group C, and a group D according to stratified random method, with 171 cases in each group. The treatment plan for the group A was Jinghua Weikang capsules+Ornidazole capsules+ Pantoprazole+Amoxicillin, 10 days for a course of treatment (day 1 to day 10). The treatment plan for the group B included the same treatment plan as the group A for the first 10 days, and taking Jinghua Weikang capsules from day 11 to day 28. The treatment plan for the group C was aluminum magnesium additive+Ornidazole capsules+Pantoprazole+ Amoxicillin, 10 days for a course of treatment (day 1 to day 10). The treatment plan for the group D included the same treatment plan as the group C for the first 10 days, and taking Jinghua Weikang capsules from day 11 to day 28. The eradication rate of Helicobacter pylori, the remission of symptoms and the incidence of adverse reactions at the end of treatment and 4 weeks after completion of the treatment were compared among the 4 groups. Results Schema data analysis results showed that, the eradication rate of Helicobacter pylori infection in the groups A, B, C and D was respectively 76.6%, 80.0%, 84.9% and 93.5%; there were significant differences in the radical control rate of Helicobacter pylori infection among the 4 groups (P < 0.05), the radical control rate of Helicobacter pylori infection in the group D was significantly different from those in the groups A, B and C (P < 0.05). Intention-to-treat analysis showed that, the eradication rate of Helicobacter pylori infection in the groups A, B, C and D was 74.9%, 79.5%, 82.5% and 91.8% respectively; there were significant differences in the radical control rate of Helicobacter pylori infection among the 4 groups (P < 0.05), the radical control rate of Helicobacter pylori infection in the group D was significantly different from those in the groups A, B and C (P < 0.05). There were no significant differences in the score of upper abdominal distension, upper abdominal pain, belching or anorexia among the 4 groups before treatment (P > 0.05). Compared with the pre-treatment symptom scores, the scores of upper abdominal distension, upper abdominal pain, belching and anorexia at the end of treatment and 4 weeks after completion of the treatment were significantly improved; there were significant differences in the anorexia score among the 4 groups at the end of treatment and 4 weeks after completion of the treatment (P < 0.05). There were no significant differences in the incidences of adverse reactions among the 4 groups (P > 0.05). Conclusions Jinghua Weikang capsules combined with quadruple therapy for the treatment of Helicobacter pylori infection is superior to its combination with quadruple therapy containing aluminum magnesium additive.
