Introduction: In addition to Helicobacter pylori, non-Helicobacter pylori helicobacters (NHPHs) have been diagnosed in the humans stomach that caused gastrointestinal diseases. This study aimed to evaluate the coinfection of H. pylori with NHPHs species in patients with gastric disorders in Iran.
Materials & Methods: This cross-sectional study was performed on 421 gastric biopsies form dyspeptic patients, who did not receive any treatment for H. pylori. The samples were divided into H. pylori-infected and NHPHs-infected groups, based on the rapid urease test, histological analysis of biopsies, and genotyping. After DNA extraction, genotyping of samples was performed to detect H. pylori and NHPHs with PCR of encoding genes fragments for urease A (ure A), urease B (ure B) and urease AB (ure AB).
Findings: The results of the present study revealed that 57 patients (19%) had coinfection H. pylori with one of the NHPHs,10 patients (3.3%) has coinfection of H. pylori with NHPHs for H. suis,22 patients (7.3%) had coinfection of H. pylori with NHPHs H. salomonis,17 patients(5.7%) had coinfection of H. pylori with NHPHs for H. heilmannii (5.7%) ,and 8 patients (2.7%) had Coinfection of H. pylori with NHPHs for H. felis.
Discussion& Conclusions: Based on the results of the current study, it can be conclude that difficulties and failures in the treatment of H.pylori is probably due to the coinfection of H.pylori with NHPHs species ;however, this conclusion requires further investigations.Additionally,in coinfection H. pylori with NHPHs, H. salomonis was found to be the most prevalent in Iranian patients with gastric disorders.
