Delta-9-tetrahydrocannabinol (THC)/cannabidiol (CBD) oromucosal spray was approved as add-on therapy for spasticity in patients with multiple sclerosis (MS). We show our 40-week postmarketing experience regarding efficacy and safety of THC/CBD spray in an Italian cohort of 102 MS patients. Patients were evaluated using the Expanded Disability Status Scale (EDSS) score, the Numerical Rating Scale (NRS) for spasticity, the Ambulation Index (AI), and Timed 25-Foot Walk (T25-FW) at the beginning of treatment and then every 3 months. After 4 weeks, if a clinically significant improvement in spasticity (at least 20% of baseline NRS score) was not seen, administration of the drug was stopped. In our cohort, patients received an average of 6.5 ± 1.6 sprays each day. The mean reduction to the NRS spasticity score was 2.5 ± 1.2 points (P < .0001). Thirty-seven patients (36.2%) discontinued the treatment. The incidence of adverse events (AEs) was 40.2%. Fifty-eight patients (56.9%) were also assessed using the NRS for pain, and 46 patients (45.1%) with bladder dysfunction were assessed for the IPSS (International Prostatic Symptoms Score) score, showing a significant improvement in these scales (P = .011 and P = .001, respectively). In conclusion, treatment with THC/CBD spray appears to be a valid answer to some of the unmet needs in MS patients, such as spasticity and other refractory-to-treatment symptoms.
ObjectiveBenefits and risks of new therapies in Multiple Sclerosis (MS) must be balanced carefully and tailored to patients. We aimed to describe our experience with Fingolimod (FTY), correlating demographics, clinical and hematological features of the Relapsing MS (RMS) cohort with the occurring Adverse Events (AEs).Material and MethodsPretreatment screening tests, cardiological observation, and safety follow‐up data were analyzed in 225 RMS patients. Changes in continuous data were analyzed post hoc with Wilcoxon ranks test; categorical variables were examined using McNemar test. Two‐way repeated‐measures analysis of variance (ANOVA) was used to analyze differences between baseline characteristic of the cohorts and Liver Function Tests (LFT) alterations. Binary logistic regression models were used to identify which of the baseline factors influenced LFT alterations and the occurrence of infections.ResultsDuring 2 years of follow‐up 24 patients (10%) interrupted FTY. Discontinuation most often was due to AEs (n = 14) or breakthrough disease (n = 5). The most frequently AEs were infections (10.6%). After the first year patients showing an infectious episode were mostly female (p = .04). The infections did not correlate with the decrease in white blood cells or to lymphocyte count. AST and ALT alterations were observed mostly in males (p = .002 and p = .01, respectively), and increase in GGT was reported in subjects older at FTY beginning (p < .05).ConclusionsFor a patient‐centered safety monitoring of FTY, we may apply gender‐specific warnings, for the detection of transaminases abnormalities and infectious episodes.
Cognitive impairment (CI) is a common and disabling symptom of Multiple Sclerosis (MS) with a negative impact on daily living. In this pilot study, we applied magnetoencephalography (MEG) and high density (hd) electroencephalography (EEG) study to evaluate acoustic P300 features in a cohort of early MS. Sixteen MS patients (pwMS) and 19 healthy controls (HCs) matched for age and gender underwent an MEG-/(hd)-EEG-co-recording, using 306-channel Vectorview and 64 scalp electrodes. CI was assessed using Rao’s Brief Repeatable Battery (BRB). Moreover, we performed psychometric tests to assess depression and fatigue. In pwMS, we observed a slight latency prolongation of P300 peak compared to HCs, while P300 amplitude and scalp distribution were similar in the two groups. pwMS did not show an amplitude reduction and different scalp distribution of Event-Related Potentials (ERPs) and Event Related Fields (ERFs) related to an acoustic oddball paradigm. We found an inverse correlation between P300 amplitude and fatigue (r Spearman = −0.4; p = 0.019). In pwMS, phenomena of cortical adaptation to early dysfunction could preserve the cognitive performance of the P300 acoustic task, while the development of fatigue could prospectively lead to amplitude decline of P300, suggesting its possible role as a biomarker.
Introduction: In relapsing Multiple Sclerosis (RMS) patients treated with disease modifying drugs (DMDs), few data are available regarding the biomarkers of treatment response. We aimed to assess the predictive value of lymphocyte count (LC) and Body Mass Index (BMI) for treatment response in a real life setting of dimethyl fumarate (DMF) treated patients. Materials and Methods: We included in our observational analysis 338 patients who were prescribed DMF in an Italian MS Center. We collected clinical and demographic data at the beginning of DMF (T0), and assessed White Blood Cells (WBC) and LC at T0 and at 3 (T3), 6 (T6), 9 (T9), and 12 (T12) months. Gadolinium enhancing (Gd+), new T2 lesions and relapses within the first year of treatment (T12) were recorded in order to evaluate clinical activity at 12 months. Analysis of correlation was performed to correlate WBC, LC and BMI with clinical and radiological responses. We evaluated whether BMI or LC can predict treatment response by using multivariate logistic regression models at each follow-up. Results: Our cohort was followed up for a mean period of 19.8 ± 6.8 months. The mean BMI at baseline was 24.19 ± 4.48. The multivariate models gave as predictive factors for Gd+ lesions at T12, LC at T3 (OR = 1.003, 95% CI = 1.00-1.07; p = 0.046) and baseline BMI (OR = 0.71, 95% CI = 0.52–0.98; p = 0.037). Predictive factors for new T2 lesions at T12 were LC at T3 (OR = 1.01 95%CI = 1.00–1.95; p = 0.005) and baseline BMI (OR = 0.99, 95% CI = 0.98–1.00; p = 0.026). Conclusions: In our real life-experience, BMI and LC may be early biomarkers to predict treatment response during DMF.
