Background:Multiple sclerosis (MS) is believed to be an autoimmune disease occurring in genetically predisposed individuals after an appropriate environmental exposure such as viral infections. Recent studies suggest a significant association between MS and the functional 5’-(GT)n polymorphism in the promoter region of the NRAMP1 gene. In the present study we aimed to evaluate the contribution of the allelic variation in the NRAMP1 promoter to MS susceptibility and to study the role of viral infection in relation to specific NRAMP1 genotypes, in a Sardinian cohort.Methods:Sixty MS patients and 66 healthy individuals were genotyped, and screened for the presence of Epstein-bar virus (EBV) and JC virus (JCV) sequences.Results:Consistent with previous autoimmune disease studies, allele 3 at the functional 5’(GT)n promoter region repeat polymorphism, was significantly overrepresented among MS patients when compared to controls (p=0.02). The EBV and JCV sequences were detected in 8/60 (13.33%) and in 4/60 (6.66%) of MS patients respectively and in 5/66 (7.57%) and in 0/66 of controls.Conclusion:The allelic variation in the NRAMP1 promoter may contribute to MS susceptibility in the Sardinian population. The viral sequences were not confined to a specific NRAMP1 genotype.

Multiple sclerosis (MS) is a common disabling neurologic disease with an overall prevalence in Canada of 240 in 100,000. Multiple sclerosis clinics are located at tertiary-care centers that may be difficult for a patient to access during an acute relapse. Many relapses are evaluated by primary-care physicians in private clinics or emergency departments, but these physicians' familiarity with MS is not known. Therefore, a survey was undertaken to determine the knowledge and experience of primary-care physicians regarding the diagnosis and treatment of MS relapses. A total of 1282 licensed primary-care physicians in the catchment area of the London (Ontario, Canada) Multiple Sclerosis Clinic were identified and mailed a two-page anonymous survey. A total of 237 (18.5%) responses were obtained, but only 216 (16.8%) of these respondents were still in active practice. Of these 216 physicians, only 9% reported having no MS patients in their practice, while 70% had one to five patients, 16.7% had six to ten, and 1.9% had more than ten (3.7% did not respond to this question). Corticosteroids were recognized as an MS treatment by 49.5% of the respondents, but only 43.1% identified them as a treatment for acute relapses. In addition, 31% did not know how to diagnose a relapse, and only 37% identified new signs or symptoms of neurologic dysfunction as indicating a potential relapse. Despite the high prevalence of MS in Canada, primary-care physicians require more education and support from specialists in MS care regarding the diagnosis and treatment of MS relapses.

Aim. This study was designed to examine the possible role of high-dose intravenous methylprednisolone (IVMP) in the development of venous thrombosis (VT). The cerebral one anecdotally had been reported in patients with relapsing remitting multiple sclerosis (RRMS) in acute attacks and the possible preventive role of enoxaparin. Material and Methods. From a pool of 520 patients, 388 patients with definite RRMS who fulfilled entry characteristics were selected and randomly received either a 5-day course of daily 1 gr IVMP or the aforementioned plus 5 days of daily subcutaneous 40 units of enoxaparin according to a predefined protocol. Results. Mean age, gender ratio, mean relapse rate, and EDSS were similar in both groups of patients (P > 0.05). Finally, 366 patients remained in the study. Of 188 patients treated with IVMP with 855 relapses, 5 developed VT (0.37% per patient per year and 0.58% per each course of IVMP) within 3 to 15 days of starting therapy. None of the 178 patients who experienced 809 relapses who received IVMP plus enoxaparin developed such complications. Conclusion. The study implies that high-dose IVMP in MS exacerbation may increase the risk of VT and prophylactic anticoagulant treatment in this setting is warranted.
