RESUMO

Importance: Transthyretin gene silencing is an emerging treatment strategy for hereditary transthyretin (ATTRv) amyloidosis. Objective: To evaluate eplontersen, an investigational ligand-conjugated antisense oligonucleotide, in ATTRv polyneuropathy. Design, Setting, and Participants: NEURO-TTRansform was an open-label, single-group, phase 3 trial conducted at 40 sites across 15 countries (December 2019-April 2023) in 168 adults with Coutinho stage 1 or 2 ATTRv polyneuropathy, Neuropathy Impairment Score 10-130, and a documented TTR variant. Patients treated with placebo from NEURO-TTR (NCT01737398; March 2013-November 2017), an inotersen trial with similar eligibility criteria and end points, served as a historical placebo ("placebo") group. Interventions: Subcutaneous eplontersen (45 mg every 4 weeks; n = 144); a small reference group received subcutaneous inotersen (300 mg weekly; n = 24); subcutaneous placebo weekly (in NEURO-TTR; n = 60). Main Outcomes and Measures: Primary efficacy end points at week 65/66 were changes from baseline in serum transthyretin concentration, modified Neuropathy Impairment Score +7 (mNIS+7) composite score (scoring range, -22.3 to 346.3; higher scores indicate poorer function), and Norfolk Quality of Life Questionnaire-Diabetic Neuropathy (Norfolk QoL-DN) total score (scoring range, -4 to 136; higher scores indicate poorer quality of life). Analyses of efficacy end points were based on a mixed-effects model with repeated measures adjusted by propensity score weights. Results: Among 144 eplontersen-treated patients (mean age, 53.0 years; 69% male), 136 (94.4%) completed week-66 follow-up; among 60 placebo patients (mean age, 59.5 years; 68% male), 52 (86.7%) completed week-66 follow-up. At week 65, adjusted mean percentage reduction in serum transthyretin was -81.7% with eplontersen and -11.2% with placebo (difference, -70.4% [95% CI, -75.2% to -65.7%]; P < .001). Adjusted mean change from baseline to week 66 was lower (better) with eplontersen vs placebo for mNIS+7 composite score (0.3 vs 25.1; difference, -24.8 [95% CI, -31.0 to -18.6; P < .001) and for Norfolk QoL-DN (-5.5 vs 14.2; difference, -19.7 [95% CI, -25.6 to -13.8]; P < .001). Adverse events by week 66 that led to study drug discontinuation occurred in 6 patients (4%) in the eplontersen group vs 2 (3%) in the placebo group. Through week 66, there were 2 deaths in the eplontersen group consistent with known disease-related sequelae (cardiac arrhythmia; intracerebral hemorrhage); there were no deaths in the placebo group. Conclusions and Relevance: In patients with ATTRv polyneuropathy, the eplontersen treatment group demonstrated changes consistent with significantly lowered serum transthyretin concentration, less neuropathy impairment, and better quality of life compared with a historical placebo. Trial Registration: ClinicalTrials.gov Identifier: NCT04136184; EU Clinical Trials Register: EudraCT 2019-001698-10.

RESUMO

OBJECTIVE: To investigate the relationship between the frequency of sleep bruxism and report of morning headaches, and associations with depression and/or anxiety. BACKGROUND: The association between sleep bruxism and headaches in the morning, and between these factors and affective disorders, has been examined in several investigations. Although headache is cited by the International Classification of Sleep Disorders as a symptom associated with sleep bruxism, only a small number of studies have investigated the association between the frequencies of headaches in the morning and bruxism. METHODS: This was a cross-sectional observational study conducted between August 2017 and May 2018 in the municipality of Curitiba, Brazil. It comprised individuals of both sexes, ages between 18 and 65 years, with no restriction of race, skin color, or social group (n = 149). Structured questionnaires were used to survey demographic characteristics, sleep bruxism, depression, and anxiety. Self-reports and clinical examinations were used together to diagnose probable sleep bruxism and assess the frequency of this condition. The presence or absence of morning headaches and their frequency were evaluated using a self-report question. It was applied to people with anxiety and/or depression and to free controls of the general population by a trained dentist. RESULTS: A significant relationship (P Ë‚ .001 - Chi-square test) was found between the frequency of sleep bruxism and morning headaches. Symptoms of depression and anxiety were associated with the presence of headache (P Ë‚ .001 - One way ANOVA), but not with the frequency of sleep bruxism. CONCLUSION: The present study confirms the hypothesis of a direct relationship between the frequency of sleep bruxism and the frequency of morning headaches. It also confirmed a linear association between mean depression scores, mean anxiety scores, and morning headaches.

RESUMO

OBJECTIVE: We assessed the efficacy and safety of once-daily eslicarbazepine acetate in comparison with twice-daily (BID) controlled-release carbamazepine (carbamazepine-CR) monotherapy in newly diagnosed focal epilepsy patients. METHODS: This randomized, double-blind, noninferiority trial (NCT01162460) utilized a stepwise design with 3 dose levels. Patients who remained seizure-free for the 26-week evaluation period (level A: eslicarbazepine acetate 800 mg/carbamazepine-CR 200 mg BID) entered a 6-month maintenance period. If a seizure occurred during the evaluation period, patients were titrated to the next target level (level B: eslicarbazepine acetate 1200 mg/carbamazepine-CR 400 mg BID, level C: eslicarbazepine acetate 1600 mg/carbamazepine-CR 600 mg BID) and the evaluation period began again. The primary endpoint was the proportion of seizure-free patients for 6 months after stabilization in the per protocol set. The predefined noninferiority criteria were -12% absolute and -20% relative difference between treatment groups. RESULTS: Eight hundred fifteen patients were randomly assigned; 785 (388 in the eslicarbazepine acetate group and 397 in the carbamazepine-CR group) were included in the per protocol set, and 813 (401 in the eslicarbazepine acetate group and 412 in the carbamazepine-CR group) were included in the full analysis set for the primary analysis. Overall, 71.1% of eslicarbazepine acetate-treated patients and 75.6% of carbamazepine-CR-treated patients were seizure-free for ≥6 months at the last evaluated dose (average risk difference = -4.28%, 95% confidence interval [CI] = -10.30 to 1.74; relative risk difference = -5.87%, 95% CI = -13.50 to 2.44) in the per protocol set. Rates of treatment-emergent adverse events were similar between groups for patients in the safety set. Noninferiority was also demonstrated in the full analysis set, as 70.8% of patients with eslicarbazepine acetate and 74.0% with carbamazepine-CR were seizure-free at the last evaluated dose (average risk difference = -3.07, 95% CI = -9.04 to 2.89). SIGNIFICANCE: Treatment with eslicarbazepine acetate was noninferior to BID carbamazepine-CR. With its once-daily formulation, eslicarbazepine acetate provides a useful option for first-line monotherapy for adults with newly diagnosed epilepsy and focal onset seizures.

RESUMO

OBJECTIVE: To evaluate the efficacy and safety of adjunctive eslicarbazepine acetate (ESL) in patients with refractory partial-onset seizures. METHODS: This randomized, placebo-controlled, double-blind, parallel-group, phase III study was conducted at 173 centers in 19 countries, including the United States and Canada. Eligible patients were aged ≥16 years and had uncontrolled partial-onset seizures despite treatment with 1-2 antiepileptic drugs (AEDs). After an 8-week baseline period, patients were randomized to once-daily placebo (n = 226), ESL 800 mg (n = 216), or ESL 1,200 mg (n = 211). Following a 2-week titration period, patients received ESL 800 or 1,200 mg once-daily for 12 weeks. Seizure data were captured and documented using event-entry or daily entry diaries. RESULTS: Standardized seizure frequency (SSF) during the maintenance period (primary end point) was reduced with ESL 1,200 mg (p = 0.004), and there was a trend toward improvement with ESL 800 mg (p = 0.06), compared with placebo. When data for titration and maintenance periods were combined, ESL 800 mg (p = 0.001) and 1,200 mg (p < 0.001) both reduced SSF. There were no statistically significant interactions between treatment response and geographical region (p = 0.38) or diary version (p = 0.76). Responder rate (≥50% reduction in SSF) was significantly higher with ESL 1,200 mg (42.6%, p < 0.001) but not ESL 800 mg (30.5%, p = 0.07) than placebo (23.1%). Incidence of treatment-emergent adverse events (TEAEs) and TEAEs leading to discontinuation increased with ESL dose. The most common TEAEs were dizziness, somnolence, nausea, headache, and diplopia. SIGNIFICANCE: Adjunctive ESL 1,200 mg once-daily was more efficacious than placebo in adult patients with refractory partial-onset seizures. The once-daily 800 mg dose showed a marginal effect on SSF, but did not reach statistical significance. Both doses were well tolerated. Efficacy assessment was not affected by diary format used.

RESUMO

BACKGROUND: Throughout history, migraine-associated visual symptoms have puzzled patients, doctors, and neuroscientists. The visual aspects of migraine extend far beyond the aura phenomena, and have several clinical implications. METHODS: A narrative review was conducted, beginning with migraine mechanisms, then followed by pertinent aspects of the anatomy of visual pathways, clinical features, implications of the visual system on therapy, migraine on visually impaired populations, treatment of visual auras and ocular (retinal) migraine, effect of prophylactic migraine treatments on visual aura, visual symptoms induced by anti-migraine or anti-headache drugs, and differential diagnosis. RESULTS: A comprehensive narrative review from both basic and clinical standpoints on the visual aspects of migraine was attained; however, the results were biased to provide any useful information for the clinician. CONCLUSION: This paper achieved its goals of addressing and condensing information on the pathophysiology of the visual aspects of migraine and its clinical aspects, especially with regards to therapy, making it useful not only for those unfamiliar to the theme but to experienced physicians as well.

RESUMO

BACKGROUND: The phase 3 NEURO-TTRansform trial showed eplontersen treatment for 65 weeks reduced transthyretin (TTR), halted progression of neuropathy impairment, and improved quality of life (QoL) in adult patients with hereditary TTR-mediated amyloidosis with polyneuropathy (ATTRv-PN), vs. historical placebo. METHODS: NEURO-TTRansform enrolled patients with ATTRv-PN. A subset of patients were randomized to receive subcutaneous inotersen 300 mg weekly (Weeks 1-34) and subsequently switched to subcutaneous eplontersen 45 mg every 4 weeks (Weeks 37-81). Change in serum TTR and treatment-emergent adverse events (TEAEs) were evaluated through Week 85. Effects on neuropathy impairment, QoL, and nutritional status were also evaluated. RESULTS: Of 24 patients randomized to inotersen, 20 (83%) switched to eplontersen at Week 37 and four discontinued due to AEs/investigator decision. Absolute change in serum TTR was greater after switching from inotersen (-74.3%; Week 35) to eplontersen (-80.6%; Week 85). From the end of inotersen treatment, neuropathy impairment and QoL were stable (i.e., did not progress) while on eplontersen, and there was no deterioration in nutritional status. TEAEs were fewer with eplontersen (Weeks 37-85; 19/20 [95%] patients) compared with inotersen (up to Week 35; 24/24 [100%] patients). Mean platelet counts decreased during inotersen treatment (mean nadir reduction ‒40.7%) and returned to baseline during eplontersen treatment (mean nadir reduction, ‒3.2%). CONCLUSIONS: Switching from inotersen to eplontersen further reduced serum TTR, halted disease progression, stabilized QoL, restored platelet count, and improved tolerability, without deterioration in nutritional status. This supports a positive benefit-risk profile for patients with ATTRv-PN who switch from inotersen to eplontersen.

RESUMO

INTRODUCTION: Successful prophylactic therapy might require not only efficacy but meeting patients' expectations about the potential side effects of the preventative drug selected. Prior to prescribing prophylactic drugs to prophylaxis-naive migraine patients, we aimed to quantify the acceptance or rejection of some of the possible adverse events associated with migraine prophylactic drugs. METHODS: A total of 203 prophylactic-naive migraine/chronic migraine patients, 17 (8.4%) male, 186 (91.6%) female, aged 19 to 65 years were serially selected and asked to answer bidirectional visual numerical scales designed for this purpose, with 1 scale for each side effect. The question posed was: "How much would you accept or reject the following side effects to get rid of your migraine headaches?" The side effects listed were dry mouth, epigastric burning, low energy, tingling, somnolence, depression, tremor, insomnia, memory loss, sluggishness, weight gain, and weight loss. RESULTS: The most rejected possible side effects were weight gain, memory loss, and depression. Weight loss was better accepted by patients with a higher body mass. In general, there was a higher acceptance of side effects for patients taking more than 10 symptomatic medications a month, especially for loss of energy and somnolence. Older patients lacked an acceptance of tremor. CONCLUSION: Our findings reinforce and quantify findings similar to those in the literature, and provide new data regarding the preference determinants for prophylactic medication.

RESUMO

Lambert-Eaton myasthenic syndrome (LEMS) is an immune-mediated disorder of the neuromuscular junction that rarely is associated with cerebellar ataxia (CA). We describe two patients with non-paraneoplastic LEMS associated with CA who showed high levels of anti-P/Q-type voltage-gated calcium channels antibodies in the serum and cerebrospinal fluid, and reduced CMAP with increment after brief maximum voluntary contraction in electrophysiological studies. We suggest that LEMS should be considered in the differential diagnosis of patients with CA.

RESUMO

Benign focal epilepsy with affective symptoms (BFEAS) is a rare childhood epilepsy syndrome essentially characterized by "epileptic attacks with affective symptoms of a terrifying type". Since the original description, approximately 50 cases have been reported. To our knowledge, however, none of the studies included video-EEG data. Herein, we detail the electroclinical features of a neurodevelopmentally normal 9-year-old boy with epilepsy since the age of 2 years. His seizure semiology essentially consisted of nocturnal focal seizures featuring abrupt fear and autonomic phenomena (such as excessive sweating, repeated swallowing, and coughing), associated with impaired consciousness. These seizures were often secondary generalized, and he had multiple episodes of convulsive status epilepticus. He has been seizure-free for the past year and a half on dual antiepileptic therapy with sulthiamine and valproate. His intellectual and social abilities are excellent (IQ of 116), although he does have difficulties particularly in language learning, and was recently diagnosed with phonological dyslexia with dysorthography. By presenting our patient's history and video-EEG, we intend to further detail the semiology of seizures with affective symptomatology.

RESUMO

PURPOSE: Pooled evaluation of the key efficacy and safety profile of eslicarbazepine acetate (ESL) added-on to stable antiepileptic therapy in adults with focal-onset seizures. METHODS: Data from 1703 patients enrolled in four phase III double-blind, randomized, placebo-controlled studies were pooled and analyzed. Following a 2 week titration period, ESL was administered at 400 mg, 800 mg, and 1200 mg once-daily doses for 12 weeks (maintenance period). Pooled efficacy variable was standardized (/4 weeks) seizure frequency (SSF) analyzed over the maintenance period as reduction in absolute and relative SSF and proportion of responders (≥50% reduction in SSF). Pooled safety was analyzed by means of adverse events and clinical laboratory assessments. RESULTS: SSF was significantly reduced with ESL 800 mg (P < 0.0001) and 1200 mg (P < 0.0001) compared to placebo. Median relative reduction in SSF was 33.4% for ESL 800 mg and 37.8% for 1200 mg (placebo: 17.6%), and responder rate was 33.8% and 43.1% (placebo: 22.2%). ESL was more efficacious than placebo regardless of gender, geographical region, epilepsy duration, age at time of diagnosis, seizure type, and type of concomitant antiepileptic drugs (AED). Incidence of adverse events (AEs) and AEs leading to discontinuation was dose dependent. Most common AEs (>10% patients) were dizziness, somnolence, and nausea. The incidence of treatment-emergent AEs (dizziness, somnolence, ataxia, vomiting, and nausea) was lower in patients who began taking ESL 400 mg (followed by 400 mg increments to 800 or 1200 mg) than in those who began taking ESL 600 mg or 800 mg. CONCLUSIONS: Once-daily ESL 800 mg and 1200 mg showed consistent results across all efficacy and safety endpoints, independent of study population characteristics and type of concomitant AEDs. Treatment initiated with ESL 400 mg followed by 400 mg increments to 800 or 1200 mg provides optimal balance of efficacy and tolerability.

RESUMO

INTRODUCTION: Sleep disorders presenting involuntary movements may be very annoying to patients, apart from their negative influence on sleep. OBJECTIVE: To report the use of botulinum type-A toxin (BoNT-A) to manage the case of a patient whose sleep was severely disrupted by episodes of dystonic posturing of the right lower limb triggered by periodic limb movements of sleep (PLMS). METHOD: A 79-year-old woman with mild post-stroke right hemiparesis presented with recurrent painful episodes of dystonia of the right lower limb, which disrupted her sleep. The dystonic episodes could also be voluntarily triggered by extension of the right hallux. Polysomnography confirmed that the dystonic episodes were triggered by PLMS. Twenty units of BoNT-A (20U/500U vial) were injected into her right extensor hallucis longus. RESULTS: Shortly after BoNT-A was injected, the dystonic symptoms abated, and the patient achieved better sleep efficiency. CONCLUSION: The PLMS-related involuntary extension of the hallux was probably triggering the nocturnal post-stroke lower limb dystonic paroxysms. BoNT-A injection into the right extensor hallucis longus was effective in managing this condition and thus resolved the associated disruption of sleep.

RESUMO

We report a 72-year-old man with a four-year history of dyscognitive seizures (with occasional secondary generalization) who developed isolated, nocturnal dry cough immediately after being started on PO phenytoin. The cough was not accompanied by any other symptom or sign as his physical exam was completely normal. Further investigation with chest CT and spirometry was unremarkable. This symptom persisted for six months and did not resolve until we weaned him off of phenytoin. According to the Naranjo Adverse Drug Reaction Probability Scale, his cough was classified as being probably (score + 6) related to the use of this antiepileptic drug. To our knowledge, there has been only one study that reported phenytoin-triggered cough. It described a postoperative patient who developed cough and bronchospasm after receiving IV phenytoin. By reporting our case and discussing the literature on this specific topic, we have essentially two goals. First, we intend to remind clinicians that isolated persistent cough can be an adverse reaction to phenytoin. Second, we hope to encourage further studies that will be able to elucidate the association presented herein.

RESUMO

Cerebral venous thrombosis- (CVT-) associated headache is considered a secondary headache, commonly presenting as intracranial hypertension headache in association with seizures and/or neurological signs. However, it can occasionally mimic migraine. We report a patient presenting with a migraine-like, CVT-related headache refractory to several medications but intravenous dihydroergotamine (DHE). The response to DHE, which is considered to be an antimigraine medication, in addition to the neurovascular nature of migraine, points out to a probable similarity between CVT-headache and migraine. Based on experimental studies, we discuss this similarity and hypothesize a trigeminovascular role in the genesis of CVT-associated headache.

RESUMO

Three world-famous neurologists, Charcot and Mitchell, in the 19th century, and Lees, in this century, all of whom had great scientific curiosity, experimented with the psychoactive drugs hashish, mescal and yagé, respectively, in an attempt to increase their knowledge of neurological diseases and how the brain works.

RESUMO

Partial and generalized tonic-clonic reflex seizures related to hot water bathing have been described as temperature-related. We describe three cases of bathing epilepsy: a 28 year-old white male and a 30 year-old white female with spells triggered either by warm or hot water, and a 32 year-old female with spells triggered by hot water. The later two of the three cases presented localized epilepsy and a familial history of epilepsy. A complex tactile stimuli might play the most relevant role on seizure triggering, as well as water temperature with an additive effect over cutaneous stimulation.

RESUMO

Forty-three patients with epilepsy resistant to drug therapy were submitted to temporal lobe epilepsy surgery at the Instituto de Neurologia de Curitiba, from 1998 to 2003. Thirty-nine patients (90.6%) had mesial temporal sclerosis, and four had brain tumors. According to Engel's rating, 83.7% from 37 patients with complete postoperative evaluation were classified as Class I (free of disabling seizure). Postoperative complications (18.6%) were evaluated, with one case of surgical wound infection, one case of hydrocephalus, one case of cerebrospinal fluid fistula, two cases of transient palsy of the trochlear nerve and one case of transient hemiparesis.

RESUMO

Trigeminal neuralgia (TN) patients may develop side effects from centrally acting drugs, have contraindications for neurosurgical procedures, or experience relapse during conventional therapies. OnabotulinumtoxinA (BoNT/A) has been reported to be effective for TN, although this finding has been challenged. An overview of the available evidence based on a narrative/qualitative analysis of the literature is presented. About 90% of patients who receive BoNT/A show an improvement, a higher figure than that reported for the placebo effect of BoNT/A for other headaches. Tolerability of BoNT/A is good, and its few side-effects are transient. The articles reviewed were mainly case reports, case series and open-label trials; however, randomized controlled trials have endorsed the efficacy of BoNT/A for TN. This evidence, together with a better understanding of the analgesic mechanisms of BoNT/A and its proven efficacy in treating other pain syndromes, supports the use of this toxin as a therapeutic option for TN.

RESUMO

Limb shaking syndrome (LSS) is a rare presentation of transient ischemic attacks (TIAs), usually secondary to a critical carotid stenosis compromising intracranial circulation, first described 40 years ago. Two additional cases are described herein, aiming to add on to previous descriptions, and to warn physicians about this potentially harming and rather uncommon condition.

RESUMO

INTRODUCTION: Refractory epilepsy accounts for 20 to 30% of epilepsy cases and remains a challenge for neurologists. Vagus nerve stimulation (VNS) is an option for palliative treatment. OBJECTIVE: It was to study the efficacy and tolerability of VNS in patients implanted with a stimulator at the Curitiba Institute of Neurology (INC). METHODS: A case study of six patients with refractory epilepsy submitted to a VNS procedure at the INC in the last four years was described and discussed. RESULTS: Mean age at time of implantation was 29 years. Mean follow-up was 26.6 months. Seizure frequency decreased in all patients (40-50% (n=2) and ≥80% (n=4)). Three patients no longer required frequent hospitalizations. Two patients previously restricted to wheelchairs started to walk, probably because of improved mood. CONCLUSION: In this population, VNS proved to be a sound therapeutic option for treating refractory epilepsy.

RESUMO

PURPOSE: This study aims to study death records mentioning epilepsy, epileptic seizures and/or status epilepticus, in order to survey the population demographics and associated medical conditions, making it possible to outline the patient's profile. METHODS: A qualitative analysis was performed on the data gathered from death certificates from the Curitiba county records ranging from 1998 to 2007 bracket, in which epilepsy, seizure and/or status epilepticus were mentioned as the basic, intermediate, immediate or associated cause of death. RESULTS: Epilepsy was mentioned on 621 death cases in this 10-year-period. The deaths were mainly of male individuals (57.3%), Caucasian (71.6%), single (48.6%) and aged between 20 and 60 years (51.8%). Most of those who died were hospitalized patients (62.5%) and in 64.3% of the reported deaths, the patient received medical care during the event that led to his/her death. Epilepsy itself was considered to be the cause of death in 44%, followed by status epilepticus (9.7%). The most common intermediary and immediate causes were pulmonary infections (11.1%) and cardiac arrest (19.2%), respectively DISCUSSION: Hospitalized younger Caucasian males with epilepsy were the most common cases in this 10-year-period survey. Pulmonary infections were a common finding, but other aspects such as previous trauma, cerebrovascular disease or neoplasm were eventual associated factors. Public health and medical preventative measures can be planned based on the results of this study.
