- Familial amyloid polyneuropathy (FAP) is a progressive disease. Patisiran is an investigational small interfering RNA (siRNA) targeting TTR. The primary objective of the Phase 2 study is to evaluate the safety of 0.3 mg/kg patisiran administered intravenously once every 3 weeks. Twenty-seven patients were enrolled; the mean duration of treatment was 7 months (range 3–12), with 282 doses administered (median of 11 doses/patient). Chronic dosing with patisiran has been generally well tolerated. Two patients experienced serious adverse events regarded as being unrelated to study drug. Infusion-related reactions were observed in 14.8% of the patients, were mild in severity, and did not result in any discontinuations. Sustained TTR lowering of at least 80% was achieved based on serial TTR measurements for over 9 months, with further nadir of up to 89.6% between doses. Neurologic impairment scores were stable after 6 months of treatment with patisiran. A mean decrease from baseline in mNIS+7 of 0.95 points (N=19) observed in this study compared favorably to the estimated increase of 7–10 points in mNIS+7 at 6 months from prior FAP studies in a patient population with similar baseline NIS values. Dosing continues in all patients, and 12–month results will be presented.

Conference paper (peer-reviewed)abstract
- Having previously demonstrated that in-patients referred to neurology at two UK hospitals were not fully examined prior to referral, we designed an audit with 80% power to detect a 10% increase in tendon hammer or ophthalmoscope use following an educational intervention. In-patients referred to neurology over a 4 month period in the UK, Jordan, Sweden and the United Arab Emirates were asked whether they recalled examination with a Tendon hammer, Ophthalmoscope and Stethoscope since admission. Results were disseminated to local medical teams and data were collected for a further 4 months. Pre and post-intervention data were available for 11 centres with 407 and 391 patients in each arm. 264 patients (64.86%) recalled examination with a tendon hammer preintervention, which significantly improved to 298 (76.21%) (p

Conference paper (other academic/artistic)abstract
- Teriflunomide, approved for the treatment of relapsing-remitting multiple sclerosis, has a well-characterized safety profile based on individual clinical studies. We report pooled safety and tolerability data from four, double-blind, placebo-controlled trials of teriflunomide. Post-approval updates on hair thinning and pregnancy outcomes, sometimes concerns for patients initiating teriflunomide, are reported.MethodsData were pooled from phase 2 (NCT01487096) and phase 3 TEMSO (NCT00134563), TOWER (NCT00751881), and TOPIC (NCT00622700) studies. Patients were randomized to receive teriflunomide 14 mg, 7 mg, or placebo. Safety analyses were performed for all patients exposed to teriflunomide.ResultsThe pooled dataset included 3044 patients. Commonly reported adverse events (AEs) were in accordance with individual clinical studies, most being transient and mild-to-moderate in intensity. Incidence of hepatic AEs was higher in teriflunomide groups; however, serious hepatic AEs were similar across groups (∼2–3%). Hair thinning was higher in teriflunomide than placebo groups, but typically resolved on treatment without intervention and led to discontinuation in <2% of patients. No structural or functional abnormalities were reported in 42 newborns from teriflunomide-exposed parents.ConclusionsThese data from >6800 patient-years of teriflunomide exposure were consistent with individual studies and no new, unexpected safety signals were observed.

Selective peripheral denervation for cervical dystonia : long-term follow-up
- 2015
-
In: Journal of Neurology, Neurosurgery and Psychiatry. - : BMJ. - 0022-3050 .- 1468-330X. ; 86:12, s. 1307-1313
-
Journal article (peer-reviewed)abstract
- OBJECTIVE: 61 procedures with selective peripheral denervation for cervical dystonia were retrospectively analysed concerning surgical results, pain, quality of life (QoL) and recurrences.METHODS: The patients were assessed with the Tsui torticollis scale, Visual Analogue Scale (VAS) for pain and Fugl-Meyer scale for QoL. Evaluations were performed preoperatively, early postoperatively, at 6 months, then at a mean of 42 (13-165) months. All patients underwent electromyogram at baseline, which was repeated in cases who presented with recurrence of symptoms after surgery.RESULTS: Six months of follow-up was available for 55 (90%) of the procedures and late follow-up for 34 (56%). The mean score of the Tsui scale was 10 preoperatively. It improved to 4.5 (p<0.001) at 6 months, and 5.3 (p<0.001) at late follow-up. VAS for pain improved from 6.5 preoperatively to 4.2 (p<0.001) at 6 months and 4 (p<0.01) at late follow-up. The Fugl-Meyer score for QoL improved from 43.3 to 46.6 (p<0.05) at 6 months, and to 51.1 (p<0.05) at late follow-up. Major reinnervation and/or change in the dystonic pattern occurred following 29% of the procedures, and led in 26% of patients to reoperation with either additional denervation or pallidal stimulation.CONCLUSIONS: Selective peripheral denervation remains a surgical option in the treatment of cervical dystonia when conservative measures fail. Although the majority of patients experience a significant relief of symptoms, there is a substantial risk of reinnervation and/or change in the pattern of the cervical dystonia.

Journal article (peer-reviewed)abstract
- - Objective: To investigate whether cerebrospinal fluid (CSF) neurogranin concentrations are altered in sporadic Creutzfeldt-Jakob disease (CJD), comparatively with Alzheimer's disease (AD), and associated with neuronal degeneration in brain tissue. Methods: CSF neurogranin, total tau, neurofilament light (NFL) and 14-3-3 protein were measured in neurological controls (NCs, n=64), AD (n=46) and CJD (n=81). The accuracy of neurogranin discriminating the three diagnostic groups was evaluated. Correlations between neurogranin and neurodegeneration biomarkers, demographic, genetic and clinical data were assessed. Additionally, neurogranin expression in postmortem brain tissue was studied. Results: Compared with NC, CSF neurogranin concentrations were increased in CJD (4.75 times of NC; p<0.001, area under curve (AUC), 0.96 (95% CI 0.93 to 0.99) and AD (1.94 times of NC; p<0.01, AUC 0.73, 95% CI 0.62 to 0.82), and were able to differentiate CJD from AD (p<0.001, AUC 0.85, 95% CI 0.78 to 0.92). CSF tau was increased in CJD (41 times of NC) and in AD (3.1 times of NC), both at p<0.001. In CJD, neurogranin positively correlated with tau (r=0.55, p<0.001) and was higher in 14-3-3-positivity (p<0.05), but showed no association with NFL (r=0.08, p=0.46). CJD-MM1/MV1 cases displayed higher neurogranin levels than VV2 cases. Neurogranin was increased at early CJD disease stages and was a good prognostic marker of survival time in CJD. In brain tissue, neurogranin was detected in the cytoplasm, membrane and postsynaptic density fractions of neurons, with reduced levels in AD, and more significantly in CJD, where they correlated with synaptic and axonal markers. Conclusions: Neurogranin is a new biomarker of prion pathogenesis with diagnostic and prognostic abilities, which reflects the degree of neuronal damage in brain tissue in a CJD subtype manner. © Author(s) (or their employer(s)) 2019.

Deep brain stimulation in the caudal zona incerta versus best medical treatment in patients with Parkinson's disease : a randomised blinded evaluation
- 2018
-

Journal article (peer-reviewed)abstract
- Background: Several open-label studies have shown good effect of deep brain stimulation (DBS) in the caudal zona incerta (cZi) on tremor, including parkinsonian tremor, and in some cases also a benefit on akinesia and axial symptoms. The aim of this study was to evaluate objectively the effect of cZi DBS in patients with Parkinson's disease (PD).Method: 25 patients with PD were randomised to either cZi DBS or best medical treatment. The primary outcomes were differences between the groups in the motor scores of the Unified Parkinson's Disease Rating Scale (UPDRS-III) rated single-blindly at 6 months and differences in the Parkinson's Disease Questionnaire 39 items (PDQ-39). 19 patients, 10 in the medical arm and 9 in the DBS arm, fulfilled the study.Results: The DBS group had 41% better UPDRS-III scores off-medication on-stimulation compared with baseline, whereas the scores of the non-surgical patients off-medication were unchanged. In the on-medication condition, there were no differences between the groups, neither at baseline nor at 6 months. Subitems of the UPDRS-III showed a robust effect of cZi DBS on tremor. The PDQ-39 domains 'stigma' and 'ADL' improved only in the DBS group. The PDQ-39 summary index improved in both groups.Conclusion: This is the first randomised blinded evaluation of cZi DBS showing its efficacy on PD symptoms. The most striking effect was on tremor; however, the doses of dopaminergic medications could not be decreased. cZi DBS in PD may be an addition to existing established targets, enabling tailoring the surgery to the needs of the individual patient.

Research review (peer-reviewed)abstract
- Neuroinflammatory diseases such as multiple sclerosis, neuromyelitis optica, chronic inflammatory demyelinating polyneuropathy and myasthenia gravis are leading causes of physical disability in people of working age. In the last decades significant therapeutic advances have been made that can ameliorate the disease course. Nevertheless, many affected will continue to deteriorate despite treatment, and the costs associated with disease-modifying drugs constitute a significant fiscal burden on healthcare in developed countries. Autologous haematopoietic stem cell transplantation is a treatment approach that aims to ameliorate and to terminate disease activity. The erroneous immune system is eradicated using cytotoxic drugs, and with the aid of haematopoietic stem cells a new immune system is rebuilt. As of today, more than 1000 patients with multiple sclerosis have been treated with this procedure. Available data suggest that autologous haematopoietic stem cell transplantation is superior to conventional treatment in terms of efficacy with an acceptable safety profile. A smaller number of patients with other neuroinflammatory conditions have been treated with promising results. Herein, current data on clinical effect and safety of autologous haematopoietic stem cell transplantation for neurological disease are reviewed.

Journal article (peer-reviewed)abstract
- Benign multiple sclerosis (BMS) is often defined by the Expanded Disability Status Scale (EDSS) score of ≤3.0 after ≥15 years of disease duration. This classification’s clinical relevance remains unclear as benign patients may suffer other impairments and advance towards a progressive course, prompting our objective to holistically investigate factors associated with BMS and its long-term prognosis.MethodsBenign cases were identified in the Swedish Multiple Sclerosis registry. Baseline clinical data, demographic features and influence of multiple sclerosis (MS) major risk alleles on likelihood of benign course were investigated. Physical disability (EDSS), cognitive function (Symbol Digit Modalities Test; SDMT) and self-reported and socioeconomic differences between benign and non-benign patients were evaluated using generalised estimation equations models.Results11222 patients (2420 benign/8802 non-benign) were included. Benign patients were more likely to be female and younger at MS onset, have fewer relapses within the first two and 5 years from onset and fully recover from the first relapse (p<0.001). No association between human leucocyte antigen (HLA) DRB1*15:01 carriership (OR: 0.97, 95% CI: 0.86 to 1.09) or HLA-A*02:01 lacking (OR: 0.99, 95% CI: 0.87 to 1.11) and benign/non-benign was found. Non-benign patients accumulated an extra 0.04 (95% CI 0.03 to 0.04, p<0.001) EDSS score/year, lost an extra 0.3 (95% CI − 0.39 to − 0.18, p<0.001) SDMT score/year and deteriorated faster in self-reported impact and socioeconomic measures (p<0.001).ConclusionPatients with BMS have a better disease course as they progress more slowly at the group level in all respects. Lack of an association with major genetic risk factors indicates that MS course is most likely influenced by either environmental factor(s) or genetic factors outside the HLA region.
