“…[134][135][136][137] Gastric MALT is specifically acquired most commonly in response to infection of the gastric mucosa by H pylori. The lymphocytes within this MALT are therefore programmed to respond to this microorganism, and the neoplastic cells of the lymphoma that may develop within this acquired MALT retain the ability to respond to the immunological proliferative drive associated with the continued presence of the microorganism.…”

“…Gastric infection by HP is actually considered to be the most relevant cause of chronic gastritis and peptic ulcer (5). It is also associated with an increased risk of mucosa associated lymphoid tissue (MALT) lymphoma and gastric cancer (6). In the past years an association between HP and various extraintestinal pathologies such as coronary heart disease and Raynaud phenomenon have been described (7)(8)(9)(10).…”

Background: Association between Helicobacter pylori (HP) infection and migraine and the effect of HP eradication on relief of migraine headache have been studied but the results are controversial. Objectives: To evaluate the effect of HP eradication in treatment of patients affected by migraine. Materials and Methods: Eighty consecutive HP infected patients affected by migraine without aura were enrolled in this clinical trial. They have referred to an endoscopy clinic for work-up of HP infection from October 2013 to November 2014. Patients were randomly assigned in 2 groups using 2 different regimens; Group A: migraine treatment and a 14-day triple therapy for HP infection and Group B: migraine treatment without HP eradication. The mean duration (hour), headache severity (MIDAS) and the frequency (per month) of clinical headache attacks were calculated upon enrollment in the study and at 6 months and 12 months after treatment. All data were analyzed using SPSS version 16. Comparison of categorical variables across the groups was performed using Chi-square test. Results: In group A, HP infection was eradicated in 34 of 40 patients (85%). After treatment in eradicated patients compared with the control group there was significant decrease in severity and frequency (but not in duration) of the migraine attacks at 6 months (p<0.001) and significant decrease in intensity, frequency and duration of the migraine attacks at 12 months (p<0.001). Conclusion: HP should be considered and examined in migranous patients and eradication treatment can be beneficial for relief of clinical attacks.

“…It is also associated with an increased risk of MALT-lymphoma and gastric cancer [7,8]. Since spontaneous clearance of the bacterium is extremely rare, at least in the absence of specific antibiotic treatment, the infection lasts for a long time.…”

Helicobacter pylori (H. pylori) has been recently associated with some organic and functional vascular disorders. In particular, our group found a high prevalence of H. pylori in patients affected by migraine and a significant improvement of migraine symptoms after eradication of the bacterium, during a follow-up period of 6 months. However, seasonal variations may affect clinical manifestations of migraine, thus influencing our previous results. The present study evaluated the effect of H. pylori eradication during a 1-year follow-up period in a population of 148 consecutively enrolled migraine patients. H. pylori infection was assessed by 13 C-urea breath test. Infected subjects underwent specific antibiotic treatment in order to eradicate the bacterium. Frequency, intensity and duration of attacks of migraine were assessed during a 1-year follow-up period. 42% of the patients showed H. pylori infection. 82% resulted eradicated. Interestingly, 28% of the patients reported a disappearance of migraine during the follow-up period. Moreover, a significant decrease of intensity, frequency and duration of the migraine attacks evaluated 2, 4, 6 and 12 months from H. pylori eradication was observed in the remaining patients. The beneficial effects of H. pylori eradication on migraine seem to be confirmed by this prolonged 1-year follow-up study.
