The clinical effect of Chitosan nanoparticles against Helicobacter pylori
The objective of this study was to observe the clinical effect of Chitosan nanoparticles therapy on Helicobacter pylori (HP) infection. Three treatment groups (A, B, and control group C) were randomly assigned with 60 cases of HP each, making 180 cases. Group C received standard triple therapy (omeprazole + amoxicillin + clarithromycin), group A got a routine dose of Chitosan nanoparticles plus triple therapy, and group B got a high dose of Chitosan nanoparticles plus triple therapy. The course of treatment in each group was 7 days. The eradication rate, clinical efficacy and adverse reactions were observed. Up to 172 patients finished the experiment, with 59 patients in Group A, 57 in Group B and 56 in Group C. In a total analysis set (FAS), the eradication rates of HP in Group A, Group B and Group C were 80.00%, 80.70%, and 71.67%, respectively. There was no significant difference between the two groups (P > 0.05). In accordance with the PPS, the HP eradication rates of group A, B, and C were 81.36%, 80.70% and 76.79%, respectively, and there was no significant difference between the two groups (P > 0.05). The clinical efficacy of group A, B, and C were 91.67%, 91.23%, and 70.00%, respectively. The differences among the three groups were statistically significant (P < 0.05). In accordance with the PPS, the clinical efficacy of group A, B and C was 93.22%, 91.23%, and 75.00%, respectively. With a P-value of less than 0.05, the results indicated that the difference between the two groups was statistically significant. There were 21 adverse reactions in the experiment, including 3 in group A, 6 in group B, and 12 in group C. The difference was statistically significant (P < 0.05) between group A and B compared with group C, the difference was statistically significant (P < 0.05); the difference between group A and group B was statistically significant (P < 0.05). In conclusion the therapeutic effect of Chitosan nanoparticles and oral liquid, combined with triple therapy on HP infection is satisfactory, with less adverse reactions are. However, the findings suggest that it is not desirable to use a high dose Chitosan nanoparticles and oral liquid.
