Helicobacter Pylori Eradication Therapy for Epileptic Children

Overview

Helicobacter pylori (H. pylori) infection is associated with several health problems. The role of H. pylori infection in epilepsy has been investigated in a few studies. To the best of our knowledge, there have been no previous studies on the effect of treating H. pylori infection on seizure frequency among children with drug-resistant idiopathic generalized epilepsy. This study aims to evaluate the effect of treating H. pylori infection on seizure frequency among children with drug-resistant idiopathic generalized epilepsy.

Helicobacter pylori (H. pylori) is a spiral-shaped Gram-negative bacterium, which causes chronic infection in more than 50% of human population. H. pylori infection is associated with several gastrointestinal disorders, such as gastritis and gastric/duodenal ulcers. Moreover, accumulating body of evidence indicates the possible role of H. Pylori infection in extraintestinal health problems, such as iron deficiency anemia, immune thrombocytopenic purpura (ITP), numerous dermatological diseases, Alzheimer disease, Parkinson's disease, multiple sclerosis, and epilepsy. Epilepsy is a common neurological disorder characterized by recurrent unprovoked seizures. This condition affects 0.5% to 1% of all children and is associated with neurobiological, cognitive, psychological, and social consequences. Seizures can usually be controlled by anti-epileptic drugs (AEDs) in up to two-thirds of children with epilepsy. However, this leaves a significant part of epileptic children whose seizures are not controlled by pharmacotherapy. The development of epilepsy is highly complex and can be attributed to multiple etiologies classified into structural (e.g., malformation, trauma, ischemia), genetic, infectious, metabolic, and immune factors. However, the etiology remains unknown in about half of epileptic children. Idiopathic generalized epilepsies (IGE) constitute about one-third of all epilepsies. Efforts to explore new possible mechanisms contributing to the development of epilepsy, particularly drug-resistant IGE, could contribute to the development of new therapeutic strategies to improve patients' outcomes. The role of H. pylori infection in epilepsy has been investigated in a few studies, some of which reported that the seroprevalence of H. pylori infection is significantly higher in patients with idiopathic epilepsy compared with patients with other chronic diseases, and that H. pylori infection is associated with poor prognosis. Potential H. pylori-induced epileptic effects are probably immune-mediated that can be attributed to a cross-mimicry mechanism between H. pylori and human cellular phospholipids with production of autoimmune antibodies (e.g., anti-cardiolipin) and H. pylori infection-related activation of pro-inflammatory cells with systemic release of proinflammatory cytokines (e.g., IL-6, 8 and TNF- α) which are involved in disruption of the blood-brain barrier and neuroinflammation. To the best of our knowledge, there have been no previous studies on the effect of treating H. pylori infection on seizure frequency among children with drug-resistant IGE. This study aims to evaluate the effect of treating H. pylori infection on seizure frequency among children with drug-resistant IGE.
