A new study on the association between Helicobacter pylori and multiple sclerosis (MS) entitled “Helicobacter pylori infection as a protective factor against multiple sclerosis risk in females” was published in the Journal of Neurology, Neurosurgery & Psychiatry by Marzena J. Fabis Pedrini from the Centre for Neuromuscular and Neurological Disorders at the QEII Medical Centre in Australia, along with colleagues.
Helicobacter pylori (H. pylori) is a gram-negative bacterium that chronically infects more than 50% of the human population. This infection increases the probability of gastric diseases including peptic ulcers and gastric cancer. H. pylori infection has been associated with the development and progression of neurological diseases, such as Parkinson, Alzheimer’s, Guillain-Barré syndrome, multiple sclerosis, and ischemic stroke, mainly due to the induction of systemic inflammation, molecular mimicry, and interference with the absorption of drugs. Studies have shown a relationship between H. pylori and multiple sclerosis (MS), but with conflicting findings.
In this study, the research team investigated the impact of H. pylori infection in multiple sclerosis (MS). The researchers included in the study 550 patients with MS and 299 controls with similar age and gender. They evaluated the clinical and demographic parameters of the individuals and used an enzyme immunoassay to detect the presence of specific IgG antibodies against H. pylori in the serum sample of patients with MS and controls.
