Abstract
AIM
To evaluate the efficacy and safety of Bifidobacterium combined with ilaprazole-containning quadruple therapy in rescue eradication of Helicobacter pylori (H. pylori).
METHODS
Two hundred and eighty H. pylori infected patients who failed initial treatment were randomly divided into four groups: A-D. Group A was treated with ilaprazole, amoxicillin, furazolidone, and colloidal bismuth pectin for 14 d. Group B was simultaneously given Bifidobacterium for 14 d on the basis of the therapy in group A. Groups C and D were, respectively, given Bifidobacterium for 28 d before the same therapy in groups A and B. H. pylori eradication was assessed by C13-urea breath test (C13-UBT), and the incidence of adverse reactions was compared in the four groups at 4 wk after treatment.
RESULTS
In total, 251 patients completed the treatment and follow-up according to the experimental design. Intention-to-treat (ITT) analysis showed that the H. pylori eradication rates in groups A, B, C, and D were 62.85, 71.43, 75.71, and 77.14, respectively, and per-protocol (PP) analysis showed that the eradication rates in groups A, B, C, and D were 72.13, 79.36, 84.13, and 84.38, respectively. The eradication rates in groups B, C, and D were significantly higher than that in group A (P < 0.05), and the eradication rates in groups C and D were significantly higher than that in group B (P < 0.05), while no statistically significant difference was found between groups C and D (P > 0.05). The completion rates in groups A, B, C, and D were 87.14 (61/70), 90.00 (63/70), 90.00 (63/70), and 91.43 (64/70), respectively. The completion rates in groups B, C, and D were significantly higher than that in group A (P < 0.05), while there was no significant difference in the completion rates among group B, C, and D (P > 0.05). The incidence of adverse reactions in groups A, B, C, and D was 14.92, 10.61, 7.46, and 6.06, respectively. The incidence of adverse reactions in groups B, C, and D was significantly lower than that in group A (P < 0.05), and the incidence of adverse reactions in groups C and D was significantly lower than that in group B (P < 0.05), while there was no significant difference in the incidence of adverse reactions between groups C and D (P > 0.05).
CONCLUSION
Bifidobacterium can effectively improve the rescue eradication rates of H. pylori, decrease the incidence of adverse reactions, and improve the compliance with treatment. The optimal strategy for rescue eradication is 28 d of Bifidobacterium before the ilaprazole-containning quadruple therapy.
