    ABSTRACT: The cerebrospinal fluid levels of interleukin-1 beta and structural magnetic resonance parameters of cortical damage, i.e., cortical lesion number and volume, and global cortical thickness, were analysed in multiple sclerosis patients at clinical onset. Cerebrospinal fluid interleukin-1 beta levels strongly correlated with cortical lesion load and cortical thickness, while correlation with white matter lesion load was modest. Interleukin-1 beta, intrathecally produced by infiltrating lymphocytes and activated microglia, may constitute a possible link between inflammation and neurodegeneration in multiple sclerosis.

    ABSTRACT: Background: To what extent the progressive increase in the incidence of multiple sclerosis (MS) observed in the province of Padova over the period 1970-1999 was an expression of a real increased risk of developing MS remained unclear. Objective: The objective of this paper is to update the epidemiological figures of MS and probe whether the risk of having MS has increased in the province of Padova during the decade 2000-2009. Methods: All patients born in Italy and having a diagnosis of MS or possible MS identified through analysis of all available sources of information were included in the study. The incidence and prevalence rates between 2000 and 2009 were obtained and compared with our previously published data. Results: On 31 December 2009, the overall prevalence was 139.5/100,000, 192.0 +/- 9.5 for females and 83.9 +/- 6.3 for males. During the decade 2000-2009, the overall incidence rate of MS was 5.5 +/- 0.5, 7.4 +/- 0.8 for females and 3.5 +/- 0.6 for males. The onset-diagnosis delay, the female/male ratio and the mean age at onset did not significantly change compared to the prior period of observation. Conclusion: Our findings support the hypothesis of a real increased risk of developing MS in the province of Padova. Moreover, the actual prevalence of 1.4/1000 makes our region a high-risk geographical area for MS. The role played by exogenous factors in determining susceptibility to MS needs to be thoroughly investigated.

    ABSTRACT: The intrathecal production of immunoglobulin (Ig) is a major biological feature of multiple sclerosis (MS), and immunopathological studies have suggested a primary role of the humoral immune response in causing irreversible brain damage. To evaluate whether, in the early phases of MS, intrathecal Ig synthesis correlates with the presence of cortical lesions (CLs), and if their association could predict the clinical course of the disease. Eighty-six patients presenting with symptoms and signs suggestive of MS underwent a diagnostic work-up that included magnetic resonance imaging and cerebrospinal fluid examination. The risk ratios (RR) for conversion to MS and for a new disease activity were calculated. Patients with clinically isolated syndromes (CIS) having CLs and intrathecal synthesis of Ig had the highest risk of conversion to MS (RR = 3.4; Wald 95% CI = 1.7-7.0, p < 0.001) whereas CIS patients without CLs and intrathecal synthesis of Ig had the lowest risk of conversion to MS (RR = 0.1, Wald 95% CI = 0.02-0.7, p < 0.001). The highest risk of having disease-related activity during the follow-up was observed in CIS and relapsing-remitting MS patients showing CLs and intrathecal Ig synthesis (RR = 2.1; Wald 95% CI = 1.5-3.1, p < 0.001) while the lowest in CIS and relapsing-remitting MS patients without CLs and intrathecal Ig synthesis (RR = 0.3; Wald 95% CI = 0.1-0.7, p < 0.001). We observed that the association of intrathecal immunoglobulin synthesis and CLs was highly predictive of an earlier CIS conversion to MS as well as of a higher disease activity.
