Abstrakt:	Objective: To evaluate the association of traumatic brain injury (TBI) before the multiple sclerosis (MS) onset with the rate of progression of neurological disorders and cerebrospinal fluid markers of blood-brain barrier permeability, inflammation, demyelination, and gliosis. Material and Methods: Patients with relapsing-remitting MS in the Altai region of Russia with/without TBI before the MS onset ( n= 44; 19 men, 25 women in each group) participated in a prospective, controlled, randomized study. Disability rate was assessed retrospectively. Pleocytosis, levels of protein, albumin, C-reactive protein, TNF-alpha, myelin basic protein, S100 protein were measured in the cerebrospinal fluid in subgroups of patients ( n= 14 in each group) in MS remission and exacerbation. Results: Concussion and mild brain contusion were documented in the group of patients with TBI before the MS onset in 35 (79.5%) and 9 (20.5%) patients, respectively. Traumatic brain injury was over the age of 15 in 72.5% of patients. The rate of MS progression was higher in the group with TBI compared to the group without TBI (0.76±1.28 and 0.40±0.43 EDSS points per year, respectively; p =0.014). TBI before the MS onset increases the risk of disability by more than 0.25 EDSS points per year (OR 2.74; 95 CI 1.10-6.85; p =0.029). Intergroup differences in cerebrospinal fluid parameters were not found either during MS exacerbation or remission. Conclusion: Concussion or mild brain contusion before the MS onset may be factors influencing the progression of neurological deficit in MS. It seems relevant to study the mechanisms of adverse effects of TBI on the MS progression.
