PCR analysis and specific immunohistochemistry revealing a high prevalence of non‐Helicobacter pylori Helicobacters in Helicobacter pylori‐negative gastric disease patients in Japan: High susceptibility to an Hp eradication regimen

Background The clinical significance of non‐ Helicobacter pylori Helicobacter (NHPH) is still unknown. There are many reports of NHPH‐infected patients suffering from gastric diseases. Here, we investigated the polymerase chain reaction (PCR) positivity of NHPH infection in gastric disease patients who were negative for H. pylori (Hp) by the rapid urease test and by pathological observation. Materials and methods We collected the 296...
