Abstract
AIM
To examine the effect of Helicobacter pylori (H. pylori) eradication therapy on the extra-gastrointestinal factors in elderly patients by a before-after observational study in community medicine.
METHODS
Medical records (1 May 2013-31 January 2014) of 130 patients who underwent H. pylori eradication therapy with 2-year after-eradication observation in our institute were reviewed. Data on sex; age; body weight; body mass index (BMI); mean corpuscular volume (MCV); total protein; low-density lipoprotein cholesterol, triglyceride, haemoglobin A1c and haemoglobin levels and gastric hyperplastic polyps (GHPs) at eradication was extracted. Two-year after-eradication change in data was analysed by paired-sample t-test; relationship between GHPs and subclinical iron deficiency anaemia (IDA) improvement was evaluated.
RESULTS
The mean patient age (median, interquartile range) at eradication was 69.6 (71.5, 64-77) years. Paired-sample t-tests showed that body weight, BMI and MCV increased by 0.52 kg (P = 0.018), 0.25 kg/m2 (P = 0.006) and 0.83 fL (P < 0.001), respectively. The nonparametric Mann-Whitney test showed no significant difference in the change rate of MCV after eradication between the groups with and without GHPs (P = 0.892).
CONCLUSION
H. pylori eradication therapy prevented weight loss and subclinical IDA in elderly individuals. GHPs were not associated with subclinical IDA.
Core tip: The effect of Helicobacter pylori (H. pylori) eradication therapy on the extra-gastrointestinal factors in elderly patients was focused in this study. H. pylori eradication therapy prevented weight loss and subclinical iron deficiency anaemia (IDA) in elderly individuals. Gastric hyperplastic polyps were not associated with subclinical IDA. The results obtained in this study will help physician to treat elderly patients in community-based medicine.
