Association of Helicobacter Pylori Infection and Migraine

Overview

The study aims to assess the relation between migraine and H pylori infection in children and adolescent.

Migraine is one of the most common types of headaches worldwide, affecting 12-15% of the world population, more common in women and also the main headache for which patients refer to specialist nerve clinics. Migraine is a complex neurovascular condition involving vasodilatation of intracranial and extracerebral blood vessels. This results in activation of trigeminal sensory nervous pain pathway leading to headache. Serotonin and reserpine (serotonin evacuator) play a notable role in the development of migraine headache by increasing cerebral blood flow. Migraine is characterized by episodic attack that may be moderate to severe in intensity, focal in nature, have a throbbing quality. Compared to adults, pediatric migraine is shorter in duration and often has bilateral, bifrontal in the point of location. Migraine is divided into two main types of migraine are: migraine with aura in which patients experience transient visual or sensory symptoms (including flickering lights, spots, or pins that develop 5-20 minutes before attacks), occurring in approximately 25% of patients with migraine, and migraine without aura, occurring in the remaining 75% of patients . Helicobacter pylori infection is a significant risk factor for migraine with no observational difference between two types (migraine with and without aura). Eradication treatment was helpful on the clinical improvement of pain. H. pylori is a gram-negative, microaerophilic, spiral bacterium with increased motility by multiple unipolar flagella. It generates urease and colonizes the mucus layer adjacent to the gastric mucosa, usually being responsible for gastrointestinal impairments such as chronic active gastroenteritis, infection, gastric and duodenal ulcer, and, more rarely, stomach cancer, also may be the result of various extra-digestive conditions such as neurological, cardiovascular, metabolic, hematologic, ocular, or dermatological ones. A research explained that gastrointestinal neuroendocrine cells such as enterochromaffin cells (EC cells) can synthesize and secrete serotonin (5-hydroxytryptamine; 5-HT) and some factors that motivate the cell to secrete 5-HT can cause central nervous system (CNS) perturbation via the brain-gut axis. Inflammation motivates the cell to secrete 5-HT e.g., when H. pylori infect a cell. Eradication of H. pylori infection has helpful outcomes to improve clinical attacks by the effect of eradication therapy on the inflammation induced high levels of 5-HT . Other theory suggests that during the infection, superoxide radicals and NO are produced and prolonged oxidative injury caused by the persistent infection might be involved in regional cerebral flow changes during migraine .
