Objective To measure the relative risks of Barrett’s esophagus (BE) associated with demographic factors, measures of adiposity and smoking among patients with gastroesophageal reflux disease (GERD). Methods Patients newly diagnosed with specialized intestinal metaplasia (SIM) (n=197) were compared to patients with GERD (n= 418) in a community clinic-based case-control study. Case sub-groups included those with any visible columnar epithelium (VBE) (n=97), and those with a long segment (=2cm) of columnar epithelium (LSBE) (n=54). Results Risks increased with older age (adjusted odds ratio (aOR) per decade for SIM=1.3, 95% confidence interval (CI)= 1.1–1.5; VBE aOR=1.4, CI=1.1–1.6; LSBE aOR=1.5, CI=1.2–1.9), male gender (SIM aOR=1.5, CI=1.1–2.2; VBE aOR=2.7, CI=1.6–4.5; LSBE aOR=3.9, CI=1.9–8.1) and possibly Asian race. Increased risk of BE in particular was observed with high waist-to-hip ratio (WHR, male high: =0.9, female high: =0.8) (SIM aOR=1.3, CI=0.9–2.1; VBE aOR=1.9, CI=1.0–3.5; LSBE aOR=4.1, CI=1.5–11.4). These associations were independent of body mass index (BMI) for the VBE and LSBE case groups but not for SIM which was the only case group in which BMI was a significant risk factor. Ever smoking cigarettes increased risk similarly for all case groups (SIM aOR=1.8, CI=1.2–2.6; VBE aOR=1.6, CI=1.0–2.6; LSBE aOR=2.6, CI=1.3–4.9), although dose response relationship was not detected for duration or intensity of smoking. Conclusions Older age, male gender and history of smoking increased risk of SIM and BE among GERD patients independent of other risk factors for BE. Central adiposity was most strongly related to risk of VBE and LSBE. These results may be useful in development of risk profiles for screening GERD patients.

“…Each subject was examined for the presence of serum anti-H. pylori immunoglobulin G (IgG) with an H. pylori enzyme immunoassay kit (AMRAD, Melbourne, VIC, Australia). 4 The results are expressed quantitatively; a titer of less than 30 U/ml was considered to be negative. H. pylori was eradicated with omeprazole (Astra Hässle AB, Mölndal, Sweden) and two types of antibiotic (clarithromycin; Taisho Pharmaceutical, Tokyo, Japan, and amoxicillin; Fujisawa Pharmaceutical, Osaka, Japan).…”

We investigated the relationship between Helicobacter pylori infection and the histologic features of gastritis in gastroduodenal disease, and evaluated the diagnostic usefulness of the polymerase chain reaction (PCR) assay for the detection of H. pylori before and after eradication therapy. Endoscopic biopsy specimens from 81 patients with gastroduodenal disease were examined for the presence of H. pylori by culture and histologic examination. Histologic features of gastritis were classified according to the updated Sydney System, and results of the PCR assay were compared with those of histologic examination, using histologic scores. The density of H. pylori was significantly correlated with polymorphonuclear neutrophil activity and chronic inflammation. These findings suggest that the grades of infiltration of polymorphonuclear neutrophil cells and chronic inflammatory cells correspond to the density of H. pylori infection assessed by the updated Sydney System. Patients with positive results on PCR assay and negative results on histologic examination may have a low density of H. pylori because of severe atrophy in the gastric mucosa. Differences in results for the PCR assay and histologic examination were found in 2 of 12 patients in the detection of H. pylori after eradication therapy. According to the results of the PCR assay and histologic features before and after eradication, the gastric tissue-based PCR assay for H. pylori after eradication may be too sensitive to judge successful eradication of H. pylori.
