Since infection at a young age is believed to result in chronic atrophic gastritis and gastric cancer in adult life, it is logical to consider a future massive programme of eradication and immunization. Regimens suggested for H. pylori eradication are a combination of inhibitors of gastric acid secretion plus two antibiotics for 7-10 days. The following study shows that MAO is low in persons who suffer from migraines, indicating that a possible copper deficiency is associated with migraines. Also the article states that MAO is low in iron-deficiency anemia. The most readily available source of monoamine oxidase in man is the platelet, although only the B form of the enzyme is represented in this site.
Platelet activity is higher in women than in men.
The enzyme activity is generally stable and is partly under genetic control. There is some evidence that individuals with low activity have a higher psychiatric morbidity than those with high activity. Despite some negative studies, the consensus of publication dealing with schizophrenia, migraine, and alcoholism find that mean platelet monoamine oxidase activity in the patient group is lower than in the controls. Values are raised in unipolar depression. Technical differences, or patient or control group heterogeneity, might well account for the absence of unanimity in the literature.
