Evaluation of Helicobacter pylori infection in patients with eso-gastro-duodenal pathology.

Helicobacter pylori (HP) infection is one of the most frequent bacterial infections in humans. The studies performed in the last 30 years showed that this bacterium is the main cause of chronic gastritis and the main etiological agent of peptic ulcer and gastric cancer. We investigated the prevalence of HP infection in a group of 1525 patients who addressed a gastroenterology medical center between 2010-2014, in Craiova, Romania, for dyspeptic symptoms. The patients underwent a clinical, endoscopic and serologic investigation for highlighting a possible HP infection. The age of the patients with gastric duodenal pathology varied between 16 and 87 years old. Of the 1525 patients, a number of 971 (63.67%) were diagnosed with HP infection, while the rest of 554 (36.33%) were not infected. The study on the distribution of gastric duodenal pathology and HP infection showed that the lesions of the upper digestive tract and HP infection emerged quite early, a number of 29 patients being aged less than 20 years old; among these, 21 (72.41%) patients were HP positive and only eight (27.59%) were HP negative. In the age group of 20-29 years old there were recorded 184 patients, of which 120 (65.22%) were HP positive and only 64 (34.78%) were HP negative. There may be observed that in the age group of 20-29 years old, both the patients with gastric duodenal pathology and the ones with HP infection increased six times in comparison to the first decade. Most cases were recorded in the patients aged between 50 and 69 years old. The two decades comprised a total number of 607 (39.8%) patients, of which 375 (61.78%) were HP positive and 232 (38.22%) were HP negative. By evaluating the distribution of HP infection according to the social environment, there was observed that there were no significant differences between the patients coming from the urban area and the ones from the rural area, as far as the HP infection was concerned.
