The Framingham cardiovascular risk score and 5-year progression of multiple sclerosis.

BACKGROUND AND PURPOSE: Cardiovascular risk factors and comorbidities can affect the prognosis of multiple sclerosis (MS). The Framingham risk score is an algorithm that can estimate the 10-year risk of developing macrovascular disease. Our objectives were to evaluate the possible association between the Framingham risk score at baseline and MS relapses, disability, and disease-modifying therapy (DMT) choices over a 5-year follow-up. METHODS: This is a retrospective cohort study including 251 MS subjects. At baseline, we calculated the Framingham risk score considering the following variables: age, sex, diabetes, smoking, systolic blood pressure, and body mass index. MS outcomes including relapses, disability, and treatments were collected over 5 years. Cox proportional regression models were employed to estimate hazard ratios (HRs). RESULTS: A one-point increase in the Framingham risk score was associated with 31% higher risk of relapse (HR = 1.31; 95% confidence interval [CI] = 1.03, 1.68), 19% higher risk of reaching of EDSS 6.0 (HR = 1.19; 95% CI = 1.05, 3.01), and 62% higher risk of DMT escalation (HR = 1.62; 95% CI = 1.22, 3.01). CONCLUSIONS: Higher cardiovascular risk was associated with higher risk of relapses, disability, and DMT escalation in MS. Early identification, correction, and treatment of cardiovascular comorbidities should be carefully considered within MS management.

Remission of early persistent cladribine-induced neutropenia after filgrastim therapy in a patient with Relapsing - Remitting Multiple Sclerosis.

BACKGROUND: Cladribine tablets were recently approved for the treatment of Relapsing-Remitting Multiple Sclerosis (RRMS), reducing B cells and T cells, followed by reconstitution of the adaptive immune system, with transient and mild effects on the innate one. Cladribine is also the standard first-line and subsequent treatment for Hairy-Cell Leukemia (HCL), frequently complicated by neutropenic fever. Recombinant human Granulocyte Colony-Stimulating Factor (G-CSF; Filgrastim) has been proved to reduce neutropenia by increasing neutrophil count. CASE REPORT: To the best of our knowledge, we report the first case of early and persistent high grade non febrile neutropenia after oral cladribine therapy in a 49-year-old RR-MS patient, successfully treated with Filgrastim. CONCLUSIONS: This report suggests that in selected cases, cladribine requires early monitoring of blood sample as it may be responsible for early neutropenia, requiring specific treatment.

Longitudinal assessment of immuno-metabolic parameters in multiple sclerosis patients during treatment with glatiramer acetate.

OBJECTIVE: We investigated the effect of glatiramer acetate (GA) on the modulation of immune cell subpopulations and serum levels of multiple immune/metabolic markers in patients with relapsing-remitting multiple sclerosis (RRMS) to understand whether the treatment with GA could induce a specific change in the immunometabolic asset of patients with RRMS. MATERIAL AND METHODS: We performed an extensive peripheral blood immunophenotyping and measured serum levels of several parameters involved in the pathogenesis of RRMS and also relevant in the pathogenesis of metabolic syndrome and obesity such as leptin, soluble leptin-receptor (sLep-R), myeloperoxidase (MPO), soluble CD40 ligand (sCD40-L), soluble tumor necrosis factor-receptor (sTNF-R), monocyte chemoattractant protein 1 (MCP-1), soluble Inter-Cellular Adhesion Molecule-1 (sICAM-1) and osteoprotegerin (OPG), in 20 naïve-to-treatment RRMS patients and 20 healthy controls. We repeated these analyses over time at 6 and 12 months after starting GA treatment. RESULTS: Our analysis showed that naïve-to-treatment RRMS patients had a lower number of CD16(+)CD56(+) NK cells, CD19(+) B cells, CD4(+) T cells co-expressing the MHC class II activation marker HLA-DR (CD4(+)DR(+)) and naïve CD4(+)CD45RA(+) T cells in basal conditions. GA treatment induced a specific and significant decrease of circulating CD19(+) B cells. Naïve-to-treatment RRMS patients also showed a significantly higher number of CD4(+) T cells with a memory phenotype (CD4(+)CD45RO(+)) whose peripheral frequency was not affected by GA treatment. These changes over time associated with a higher serum concentration of leptin and lower levels of MPO. GA treatment also reduced significantly the circulating levels of sCD40-L and sTNF-R overtime. CONCLUSIONS: Our data suggest that the clinical outcome of GA treatment is associated with changes in immune cell subpopulations and modulation of specific immunometabolic markers. These data add substantial evidence of the immune modulating effect of GA during RRMS and could be of relevance in understanding the pathogenesis of disease and its follow-up.
