Efficacy of fingolimod and interferon beta-1b on cognitive, MRI, and clinical outcomes in relapsing-remitting multiple sclerosis: an 18-month, open-label, rater-blinded, randomised, multicentre study (the GOLDEN study)

: Cognitive impairment (CI) affects 40-65% of multiple sclerosis (MS) patients. This study attempted evaluating the effects of fingolimod and interferon beta-1b (IFN β-1b) on CI progression, magnetic resonance imaging (MRI) and clinical outcomes in relapsing-remitting MS (RRMS) patients over 18 months. The GOLDEN study was a pilot study including RRMS patients with CI randomised (2:1) to fingolimod (0.5 mg daily)/IFN β-1b (250 µg every other day). CI was assessed via Rao's Brief Repeatable Battery and Delis-Kaplan Executive Function System test. MRI parameters, Expanded Disability Status Scale scores and relapses were measured. Overall, 157 patients were randomised, of whom 30 discontinued the study (fingolimod, 8.49%; IFN β-1b, 41.18%; p ≤ 0.0001). Patients randomised to fingolimod had more severe clinical and MRI disease characteristics at baseline compared with IFN β-1b. At Month (M) 18, both treatment groups showed improvements in all cognitive parameters. At M18, relapse rate, total number and volume of T2/T1 gadolinium-enhancing lesions were higher with IFN β-1b, as well as the percentage brain volume change during the study. Safety and tolerability of both treatments were similar to previous studies. Both treatments showed improvements in cognitive parameters. Fingolimod demonstrated significantly better effects on MRI parameters and relapse rate. Imbalance in baseline characteristics and the drop-out pattern may have favoured IFN β-1b. A longer duration trial may be needed to observe the complete expression of differential effects on CI scales reflecting the between-groups differences on MRI. Although limited in size, the GOLDEN study confirms the favourable benefit-risk profile of fingolimod reported in previous studies

Do changes in Lactuca sativa metabolic performance, induced by mycorrhizal symbionts and leaf UV-B irradiation, play a role towards tolerance to a polyphagous insect pest?

: The increased ultraviolet radiation (UV) due to the altered stratospheric ozone leads to multiple plant physiological and biochemical adaptations, likely affecting their interaction with other organisms, such as pests and pathogens. Arbuscular mycorrhizal fungi (AMF) and UV-B treatment can be used as eco-friendly techniques to protect crops from pests by activating plant mechanisms of resistance. In this study, we investigated plant (Lactuca sativa) response to UV-B exposure and Funneliformis mosseae (IMA1) inoculation as well as the role of a major insect pest, Spodoptera littoralis. Lettuce plants exposed to UV-B were heavier and taller than non-irradiated ones. A considerable enrichment in phenolic, flavonoid, anthocyanin, and carotenoid contents and antioxidant capacity, along with redder and more homogenous leaf color, were also observed in UV-B-treated but not in AMF-inoculated plants. Biometric and biochemical data did not differ between AMF and non-AMF plants. AMF-inoculated plants showed hyphae, arbuscules, vesicles, and spores in their roots. AMF colonization levels were not affected by UV-B irradiation. No changes in S. littoralis-feeding behavior towards treated and untreated plants were observed, suggesting the ability of this generalist herbivore to overcome the plant chemical defenses boosted by UV-B exposure. The results of this multi-factorial study shed light on how polyphagous insect pests can cope with multiple plant physiological and biochemical adaptations following biotic and abiotic preconditioning

Multicentre observational study evaluating immediate and progressive switching from carbamazepine to oxcarbazepine in patients with epilepsy

This observational study was performed to identify the clinical reasons leading physicians to opt for immediate or progressive procedures when switching patients from carbamazepine to oxcarbazepine, and to evaluate the clinical feasibility of the two procedures in a general unselected patient population. Five hundred and twenty-seven patients (aged 14 years or older, treated with carbamazepine as monotherapy or in combination therapy) were recruited at 50 Italian centres and freely assigned to immediate (n=361) or progressive (n=166) switch procedures. Vital and clinical data (including seizure frequency) were comparable in the two groups at baseline. The proportion of patients with simple partial seizures only was significantly higher in the immediate group (immediate: 33.0% vs progressive: 23.5%, p=0.0275), whereas the proportion of patients on combination therapy was slightly higher in the progressive group (immediate: 47.1 vs progressive: 55.4%, p=0.0756). At the end of the switch period, overall treatment satisfaction was greater in the immediate switch group, both in patients (p<0.002) and physicians (p<0.0005). Physicians preferred the immediate over the progressive switch procedure. The only clinical features of patients found to relate to the physician’s choice of switch procedure were simple partial seizures only (favouring the immediate switch) and, possibly, combination therapy with other anti-epileptic drugs (favouring the progressive switch). “Overnight” switching from carbamazepine to oxcarbazepine also appears feasible in most patients on polytherap

Safety and tolerability of fingolimod in patients with relapsing-remitting multiple sclerosis: results of an open-label clinical trial in Italy

The safety profile of fingolimod is well established in clinical trials and post-marketing studies. This study aimed to evaluate the safety and tolerability of fingolimod in a cohort of Italian patients with relapsing-remitting multiple sclerosis (RRMS). This is a non-comparative, open-label, multicentre, interventional study conducted in patients with RRMS with no suitable alternative treatment option. Safety and tolerability of fingolimod 0.5&nbsp;mg were assessed by recording adverse events (AEs) and serious AEs (SAEs). Of the 906 patients enrolled in the study, 91&nbsp;% of the patients completed the study. AEs and SAEs were reported in 35.4 and 2.9&nbsp;% of the patients, respectively. Most common AEs reported were headache (4.1&nbsp;%), influenza (2.1&nbsp;%), lymphopenia (1.8&nbsp;%), asthenia (1.8&nbsp;%) and pyrexia (1.8&nbsp;%). Increased alanine aminotransferase levels and hypertension were reported as AE in 1.0 and 1.4&nbsp;% of the patients, respectively. Macular oedema was reported in three patients. These results emphasize the safety of fingolimod in patients representing the real-world clinical practice in the Italian population. Fingolimod was safe and well tolerated in this population, which, compared to those enrolled in pivotal trials in terms of concomitant diseases and used medications, is broader.

Description and preliminary experience with Virtual Visit Assessment (ViVA) during the COVID-19 pandemic, a structured virtual management protocol for patients with multiple sclerosis

In people with multiple sclerosis (PwMS), strict follow-up is essential. Telemedicine has the potential to overcome many of the difficulties in routine management. Herein, we present a structured protocol that can be used to remotely manage patients with MS, describing in detail the steps to be taken and exams needed at each stage. A working group was established which developed a tailored protocol that can be adapted to a variety of settings. The overall protocol consisted of 5 phases: enrolment, document sharing phase, pre-evaluation, virtual visit, and post-visit phase, which was divided into 14 individual steps. As of October 2020, 25 virtual visits have been carried out, all via Skype. The patient's caregiver was present during visits and had an active role. The average duration of the virtual visit was 24 min, and that of the pre-visit and post-visit were around 15 min each. Overall satisfaction as rated by physicians was considered high (8.0 +/- 0.5). Using the system usability scale (SUS), patients also favorably rated the virtual visit (96.6 +/- 6.1). In 20% of cases, the virtual visit was not sufficient to provide adequate information and an in-person clinical visit was recommended. The described protocol has the potential to provide benefits for the healthcare system as well as patients and their caregivers both during and beyond COVID-19 pandemic

Ventricular antitachycardia pacing therapy in patients with heart failure implanted with a cardiac resynchronization therapy defibrillator device: Efficacy, safety, and impact on mortality

Background Cardiac resynchronization therapy defibrillator can terminate ventricular tachycardia (VT) and fast VT (FVT) via antitachycardia pacing (ATP). Objectives We evaluated efficacy and safety of ATP, whether ATP induces ventricular arrhythmias after inappropriate ATP or atrial fibrillation (AF) after appropriate ATP, and whether ATP is associated with mortality. Methods A total of 1404 patients with a cardiac resynchronization therapy defibrillator were followed in a prospective multicenter observational research. All-cause mortality rates were estimated in patient subgroups in order to uncouple the trigger (VT/FVT or other rhythms causing inappropriate detections) from ATP therapy. Results Over a median follow-up of 31 months, 2938 VT/FVT episodes were treated with ATP in 360 patients. The adjusted ATP success rate was 63% (95% confidence interval [CI] 57%-69%) on FVTs and 68% (95% CI 62%-74%) on VTs. Acceleration occurred in 55 (1.87%) and syncope in 4 (0.14%) of all ATP-treated episodes. In 14 true VT/FVT episodes in 5 patients, AF followed ATP therapy. In 4 episodes in 2 patients, VT followed ATP inappropriately applied during AF. Death rate per 100 patient-years was 5.6 (95% CI 4.3-7.5) in patients with appropriate ATP and 1.5 (95% CI 0.4-6.1) in patients with inappropriate ATP (P =.045). Conclusion ATP was effective in terminating VT/FVT episodes and displayed a good safety profile. ATP therapies by themselves did not increase death risk; prognosis was indeed better in patients without arrhythmic episodes, even if they received inappropriate ATP, than in patients with ATP on VT/FVT episodes. Adverse outcomes observed in patients receiving implantable cardioverter-defibrillator therapies are probably related to the arrhythmia itself, a marker of disease progression, rather than to adverse effects of ATP
