Zusammenfassung: | Multiple sclerosis (MS) is an autoinflammatory, chronic central nervous system disease. In the pathogenesis of the disease increased nitric oxide (NO) levels play an important role. Nitric oxide (NO) has neuroprotective effects in physiological conditions, however, it is thought that excessive NO formation in MS may lead to demyelination and axonal damage. Derivatives of methylarginine including asymmetric dimethyl arginine (ADMA), L-N monomethyl arginine (L-NMMA), symmetric dimethyl arginine (SDMA) directly or indirectly reduce NO production. Our aim was to measure the levels of methylarginine derivatives and citrulline, ornithine, arginine, homoarginine levels, which are metabolites associated with NO metabolism, in MS subgroups.
[Display omitted]
•Total methylated arginine load of the MS group were higher than the control group.•Citrulline / Arg ratio was significantly higher in MS than control.•ADMA levels positively correlated with EDSS scores of patients.•Monitoring of methylarginines may be important in chronic diseases such as MS. |
