RESUMO
Multiple sclerosis is a chronic inflammatory disease of the central nervous system (CNS). Although the exact etiology of multiple sclerosis is unknown, researchers suggest that genetic, environmental, and microbial factors play a central role in causing multiple sclerosis. Pathology of multiple sclerosis is based on inflammation as T cells enter the brain via disruptions in the blood-brain barrier, recognizing myelin as foreign antigen; and as a result, the T cells attack myelin and start the inflammatory processes, enhancing inflammatory cytokines and antibodies. Since previous studies show ethanol can suppress the immune system such as innate, humoral, and cellular immunity and increases the production of anti-inflammatory cytokines, we hypothesized maybe ethanol also have ameliorating effects on multiple sclerosis symptoms. Although alcohol induces apoptosis in oligodendrocytes and neurons, causing demyelination and affects CNS directly, in this study we will investigate ethanol's effects on some aspects of the immune system in multiple sclerosis.
RESUMO
Multiple Sclerosis (MS) is an autoimmune, inflammatory disease of the central nervous system (CNS) mostly affecting young adults. The exact mechanism and pathogenesis of MS remain still undiscovered but there have been useful treatments with different efficacy rates. Most of these therapies are divided into the first line, second line and third line, impact on the immune system and immune cells. These drugs are approved to be useful in MS, but like any other therapies, adverse effects (AE) are associated with these drugs. In this review, we continue the survey over mechanisms of actions and AEs of MS drugs. Physicians must be aware of such AEs and complications to choose the best drug for each patient.
