Multiple sclerosis (MS) is a chronic inflammatory demyelinating and degenerative disease of the central nervous system. There were 33 335 people with MS in Australia 2021 2917 New Zealand 2006 prevalence incidence are increasing time. Although new treatments have substantially improved outcomes recent decades, treatment landscape has become increasingly complex due to expanding number disease-modifying therapies (DMTs) associated safety considerations. A total 80 consensus recommendations...

In aquaporin-4 antibody-positive neuromyelitis optica spectrum disorder (AQP4-IgG NMOSD), disability accrual is mostly attributed to relapses. This study aimed assess the prevalence of progression independent relapse activity (PIRA) and relapse-associated worsening (RAW) in AQP4-IgG NMOSD. was a retrospective cohort patients with NMOSD enrolled MSBase international data registry. Patients required minimum 3 recorded Expanded Disability Status Scale (EDSS) scores: baseline, event, 6-month...

An iterative modified Delphi process was used to develop 80 consensus recommendations for management MS in Australia New Zealand. Part 1 these guidelines includes related selection initial disease-modifying therapy (DMT) MS, assessments before commencing DMT, monitoring activity on switching discontinuing DMT.

ABSTRACT Background Most patients with aquaporin‐4 antibody‐positive neuromyelitis optica spectrum disorder (AQP4‐IgG NMOSD) require life‐long immunosuppression to prevent relapses. Patients who are untreated or undergo de‐escalation of therapy typically experience severe disabling We present a series who, despite not receiving immunosuppression, developed minimal disability. Methods Case from UK national NMOSD referral centre. defined benign disease as an estimated disability status scale...

Progressive multifocal leukoencephalopathy (PML) has not been reported in pediatric neuromyelitis optica spectrum disorder (NMOSD) and rarely described children. To report a case of PML childhood-onset NMOSD. A single retrospective report. Nine years after diagnosis aquaporin-4 antibody positive NMOSD, 17-year-old boy treated with rituximab presented painless right visual loss over 6 weeks coinciding CD19 repopulation.

Background Neuromyelitis optica spectrum disorder (NMOSD) can be categorised into aquaporin-4 antibody (AQP4-IgG) NMOSD or seronegative NMOSD. While our knowledge of AQP4-IgG has evolved significantly in the past decade, remains less understood. This study aimed to evaluate predictors relapses and treatment responses Methods was a multicentre, international, retrospective cohort using MSBase registry. Recurrent relapse risk assessed an Andersen-Gill model first evaluated Cox proportional...

<h3>Introduction</h3> 40–60% of people experiencing a first clinical attack myelin oligodendrocyte glycoprotein antibody associated disease (MOGAD) will develop relapsing (R-MOGAD). The accurate risk prediction R-MOGAD is challenging. <h3>Objective</h3> To study the value combined predictive model for developing using features described by prior research studies. <h3>Methods</h3> A multivariate binary logistic regression was applied on retrospective dataset patients with MOGAD from...

Moreover, are no guidelines on acute treatment cancer-associated stroke optimal anticoagulation. This case report illustrates significance these practice gaps.
