The aim of the present prospective investigation was to study 49 dyspeptic Helicobacter pylori (HP)-positive (HP+) or -negative (HP), CagA+ and CagA- patients with a normal pattern or pure chronic gastritis at initial histology as well as normal features or hyperemic gastropathy at initial endoscopy in a two-year follow up. All the HP+ patients were treated with omeprazole 20 mg twice a day plus amoxicillin 1 g twice a day for two weeks. No substantial change was seen in gastritis in CagA+ patients in whom the infection was not eradicated, and, in contrast, a progressive improvement in 13/14 successfully treated patients was found. At endoscopy, a progressive change to a normal picture was seen in 8 and no change in 6 of 14 patients whose HP infection was eradicated, in contrast a worsening in the 9 HP+ patients who were still infected was observed. In particular, peptic lesions arose in 6 of 21 CagA+ patients in whom the infection was not eradicated. In conclusions, the lack of change in chronic gastritis at histology and the progressive worsening of endoscopic hyperemic gastropathy (with peptic lesions arising in 28,6%) when HP+ CagA+ infection is not eradicated, unlike the progressive improvement of the anatomoclinical condition in the patients whose infection was eradicated, draws attention to the relevance of eradicating HP in CagA+ patients even when no peptic lesion is found at initial endoscopy.
