Clinical Trial Summary
Most of the studies of H. pylori eradication were conducted in academic institutes and
designed to enrolled patients who did not have comorbidities. However, patients in the real
world may comorbid with diabetes, chronic obstructive pulmonary disease, cirrhosis, chronic
kidney diseases, or others. We hypothesize that the eradication rate of H. pylori in patients
with comorbidity is poor because they may be infected with antibiotics-resistant H. pylori
strains or have poor medication adherence. Here, we design a study, which focus on the H.
pylori eradication rates by the various regimens in the real world, especially for those with
high Charlson scores. It is presumed that our data will be helpful with regard to treating
such patients with H. pylori eradication in the clinical scenario.
Description:
There is a challenge for eradicating Helicobacter pylori (H. pylori) because the resistant
strains of H. pylori are increasing. In order to overcome the challenge, the new regimens are
developed, including 14-day triple therapy, 10-day sequential therapy, 10-day bismuth-based
quadruple therapy, 10-day concomitant therapy, or 14-day hybrid therapy, which have 84%~99%
of successful eradication rates. Additionally, there is a new challenge, i.e., worldwide
population aging and increases in the proportion of patients with comorbidity. Most of the
studies of H. pylori eradication were conducted in academic institutes and designed to
enrolled patients who did not have comorbidities. However, patients in the real world may
comorbid with diabetes, chronic obstructive pulmonary disease, cirrhosis, chronic kidney
diseases, or others. Our previous study showed that the eradication rate of 10-day
clarithromycin-based sequential therapy was 81% in diabetic patients, lower than 87% in
non-diabetic patients in other study. Therefore, we hypothesize that the eradication rate of
H. pylori in patients with comorbidity is poor because they may be infected with
antibiotics-resistant H. pylori strains or have poor medication adherence. The former is
because patients may use macrolides because of chronic obstructive pulmonary disease with
airway infection, for example. The latter is because the regimen of H. pylori eradication is
complex, either three or four varieties of pills and dosage intervals for administration.
Moreover, the patients may have taken many other medications for their underline comorbidity.
These medications may have drug-drug interaction with the H. pylori eradication regimen or
make the medication adherence poor. Most of studies which were conducted in academic
institutes, patients took the H. pylori eradication regimen under the study staffs'
instruction and monitor; however, in the real world, their medication adherence for H. pylori
eradication may be compromised. Here, we design a study, which focus on the H. pylori
eradication rates by the various regimens in the real world, especially for those with high
Charlson scores. It is presumed that our data will be helpful with regard to treating such
patients with H. pylori eradication in the clinical scenario.
