BACKGROUND: The safety and efficacy of low-sodium oxybate (LXB; Xywav® ) were established in a randomized, double-blind, placebo-controlled, phase 3 withdrawal study in adults with narcolepsy with cataplexy; however, the longer-term safety profile has not yet been examined. The aim of the current analysis was to assess the time of onset and duration of common treatment-emergent adverse events (TEAEs) for LXB throughout the open-label optimized treatment and titration period (OLOTTP) and the stable dose period (SDP) portions of the main study, and the subsequent 24-week open-label extension (OLE)...

Satralizumab (Enspryng® ) is a monoclonal antibody that blocks the interleukin-6 (IL-6) receptor and is approved for the treatment of neuromyelitis optica spectrum disorder (NMOSD) in patients who are aquaporin-4 immunoglobulin G (AQP4-IgG) seropositive. Patients with NMOSD are at risk of recurrent autoimmune attacks that primarily target the optic nerves and spinal cord but may also target other regions of the central nervous system; these attacks can lead to life-long disability. In the randomized, placebo-controlled phase III SAkuraSky and SAkuraStar trials, subcutaneous satralizumab as an add-on to immunosuppressive therapy or as a monotherapy, respectively, significantly reduced the risk of relapse compared with placebo in patients who were AQP4-IgG seropositive with NMOSD...

Autism spectrum disorder (ASD) is a heterogeneous neurodevelopmental condition with a so far poorly understood underlying pathogenesis, and few effective therapies for core symptoms. Accumulating evidence supports an association between ASD and immune/inflammatory processes, arising as a possible pathway for new drug intervention. However, current literature on the efficacy of immunoregulatory/anti-inflammatory interventions on ASD symptoms is still limited. The aim of this narrative review was to summarize and discuss the latest evidence on the use of immunoregulatory and/or anti-inflammatory agents for the management of this condition...

The use of direct oral anticoagulants (DOACs) is increasing because of their superior efficacy and safety compared with vitamin K antagonists. Pharmacokinetic drug interactions, particularly those involving cytochrome P450- mediated metabolism and P-glycoprotein transport, significantly affect the efficacy and safety of DOACs. In this article, we assess the effects of cytochrome P450- and P-glycoprotein-inducing antiseizure medications on DOAC pharmacokinetics in comparison to rifampicin. Rifampicin decreases to a varying extent the plasma exposure (area under the concentration-time curve) and peak concentration of each DOAC, consistent with its specific absorption and elimination pathways...

BACKGROUND AND OBJECTIVE: Ketamine may work as an anti-inflammatory agent, and it increases the levels of vascular endothelial growth factor (VEGF) in patients with treatment-resistant depression. However, whether genes related to pro-inflammatory and anti-inflammatory cytokines and VEGF may predict the treatment response to ketamine remains unknown.Therefore the aim of this study was to analyze whether specific genes related to inflammatory processes and VEGF were associated with treatment response to low-dose ketamine in patients with treatment-resistant depression...

Daridorexant (Quviviq™) is a useful option for the treatment of insomnia disorder, which has shown efficacy in younger and older adults. It antagonises the orexin receptors, thereby reducing the wake drive. Daridorexant is the first dual orexin receptor antagonist to be approved for the treatment of chronic insomnia in the EU and has been approved for insomnia in the USA. In phase 3 clinical trials, daridorexant dose-dependently improved objective latency to persistent sleep, objective wake time after sleep onset, subjective total sleep time and, at the 50 mg dose, subjective daytime functioning compared with placebo...

BACKGROUND: Teriflunomide is a disease modifying treatment (DMT) approved for relapsing-remitting multiple sclerosis (RRMS) in adults and children. It reduces lymphocyte proliferation by inhibiting the mitochondrial enzyme dihydroorotate dehydrogenase (DHODH) and thereby the pyrimidine synthesis. Although most DMTs in multiple sclerosis (MS) modulate or inhibit the immune system in the periphery, the efficacy may improve if the agent also targets immune activity within the central nervous system (CNS), acts as a neuro-protective and enhances neuro-regeneration...

BACKGROUND AND OBJECTIVE: Cerebral venous thrombosis (CVT) is a rare disease, and data regarding direct oral anticoagulant therapy are insufficient. Apixaban could have a safer profile than other direct oral anticoagulants. We present our case series of patients with CVT treated with apixaban and a systematic review of published real-world cases. METHODS: We described our series of patients with CVT treated with apixaban and searched PubMed for similar published cases with reported complete outcome data: recanalisation rate, recurrent CVT, modified Rankin score, intracranial haemorrhage, other bleedings and mortality...

Adaptation of the brain to the presence of a drug predicts withdrawal on cessation. The outcome of adaptation is often referred to as 'physical dependence' in pharmacology, as distinct from addiction, although these terms have unfortunately become conflated in some diagnostic guides. Physical dependence to antidepressants may occur in some patients, consistent with the fact that some patients experience withdrawal effects from these medications. It is thought that longer duration of use, higher dose and specific antidepressants affect the risk of antidepressant withdrawal effects as they might cause greater adaptation of the brain...

It has now been established that a perturbation in gut microbiome composition exists in multiple sclerosis (MS) and its interplay with the immune system and brain could potentially contribute to the development of the disease and influence its course. The effects of the gut microbiota on the disease may be mediated by direct interactions between bacteria and immune cells or through interactions of products of bacterial metabolism with immune and CNS cells. In this review article we summarize the ways in which the gut microbiome of people with MS differs from controls and how bacterial metabolites can potentially play a role in MS pathogenesis, and examine approaches to alter the composition of the gut microbiota potentially alleviating gut dysbiosis and impacting the course of MS...

Anorexia nervosa is a disorder associated with serious adverse health outcomes, for which there is currently considerable treatment ineffectiveness. Characterised by restrictive eating behaviours, distorted body image perceptions and excessive physical activity, there is growing recognition anorexia nervosa is associated with underlying dysfunction in excitatory and inhibitory neurometabolite metabolism and signalling. This narrative review critically explores the role of N-methyl-D-aspartate receptor-mediated excitatory and inhibitory neurometabolite dysfunction in anorexia nervosa and its associated biomarkers...

BACKGROUND: OnabotulinumtoxinA (BTX-A) and anti-calcitonin gene-related peptide (CGRP) monoclonal antibodies (anti-CGRP mAbs) are approved drugs for chronic migraine (CM), a difficult-to-treat condition. Optimization of CM patient management by choosing the best options and determining appropriate time for switching or adding concomitant treatments are highly needed. OBJECTIVE: Evaluate clinical response to anti-CGRP mAbs in patients who switched from BTX-A due to ineffectiveness defined by different cut-offs and assess the retention rate, effectiveness, and safety of both drugs within the first 9 months of treatment...

Multiple sclerosis (MS) is a chronic autoimmune demyelinating and neurodegenerative disease of the central nervous system with a wide variety of clinical phenotypes. In spite of the phenotypic classification of MS patients, current data provide evidence that diffuse neuroinflammation and neurodegeneration coexist in all MS forms, the latter gaining increasing clinical relevance in progressive phases. Given that the transition phase of relapsing-remitting MS (RRMS) to secondary progressive MS (SPMS) is not well defined, and widely accepted criteria for SPMS are lacking, randomised controlled trials (RCTs) specifically designed for the transition phase have not been conducted...

Attention-deficit/hyperactivity disorder (ADHD) is a common and impairing mental disorder. Individuals with ADHD typically experience symptoms from awakening throughout the entire day, contributing to impaired function at home, at school, and in the workplace. Treatment is available to address the symptoms of ADHD; however, the extent to which treatments afford improved function remains less clear. Impaired function in children and adolescents, particularly in the early morning where multiple tasks must be completed, from getting out of bed, and having breakfast to leaving for school on time, is common even among stimulant-treated children, and can increase stress upon caregivers and family members...
