Levodopa-Entacapone-Carbidopa Intestinal Gel in the Treatment of Advanced Parkinson's Disease: A Single Center Real-World Experience.

Levodopa-entacapone-carbidopa intestinal gel infusion is a relatively new treatment option for advanced Parkinson's disease. We aimed to describe and analyze the characteristics of de novo levodopa-entacapone-carbidopa intestinal gel therapy in 20 consecutive patients with advanced Parkinson's disease. We assessed the profile of motor complications by evaluating the following: motor fluctuations, dyskinesias, and the freezing phenomenon at baseline (before the testing period) and before discharge. The treatment significantly reduced the duration of daily hours spent in off time compared with baseline pre-treatment values from a mean of 4.8 ± 0.9 h/day to a mean of 1.4 ± 0.5 h per day (p < 0.001). The duration and severity of peak-dose dyskinesia were also significantly reduced compared with baseline values. Out of the 10 patients who reported freezing, 8 did not present this complication at the pre-discharge assessment. Significant improvements were observed in Hoehn and Yahr scale scores in both the on and off states. The levodopa-entacapone-carbidopa intestinal gel therapy was well tolerated during the follow-up period immediately after initiation. Despite a relatively severe stage of the disease, all patients experienced a significant improvement in motor fluctuations, dyskinesias, and the freezing phenomenon.

Starting with 24-h levodopa carbidopa intestinal gel at initiation in a large cohort of advanced Parkinson's disease patients.

Continuous intra-jejunal infusion of levodopa-carbidopa intestinal gel (LCIG) is a long-term proven and effective treatment in advanced Parkinson's Disease (APD). Efficacy and safety of 16-h administration of LCIG has already been established. Additional benefits of 24-h LCIG administration have been reported in several case series and small clinical studies. The aim of this retrospective study was to compare the characteristics of patients who needed 24-h LCIG from the beginning of the DAT (device-aided treatment) with those who remained with the standard 16-h LCIG treatment and to identify particular motives if any. We initiated LCIG in 150 patients out of which in case of 62 patients (41,3%) due to unsatisfactory initial clinical benefits continuous 24-h LCIG was deemed necessary. Despite the subjective complaints and more severe clinical condition, at baseline evaluation we found statistically significant differences between 16-h LCIG cohort and 24-h LCIG cohort only in case of incidence of freezing (47% vs 65%, p = 0.03) and sudden off (32% vs 48%, p = 0.04). Wake hours/daytime LCIG does not always sufficiently improve the patient's quality of life in some patients due to persistent nighttime troublesome symptoms. Instead of labeling the patient as a non-responder, it is worth trying the 24-h LCIG dosage in a carefully selected group of patients, as there is currently no consensus on reliable criteria that serve the decision in these patients.

The impact of SARS-CoV-2 infection on the outcome of acute ischemic stroke-A retrospective cohort study.

BACKGROUND: Acute ischemic stroke (AIS) is a common complication of severe acute respiratory syndrome coronavirus 2 (SARS­CoV­2) infection (COVID-19), but the prognosis of these patients is poorly understood. PURPOSE: To explore the impact of COVID-19 on neurological outcomes in AIS patients. METHODS: A comparative retrospective cohort study was conducted in 32 consecutive AIS patients with and 51 without COVID-19 between the 1st of March 2020 and 1st of May 2021. The evaluation was based on a detailed chart review for demographic data, medical history, stroke severity, cranial and vessel imaging results, laboratory parameters, COVID-19 severity, hospitalization time, in-hospital mortality, and functional deficits at discharge (modified Rankin Scale, mRS). RESULTS: COVID-19 AIS patients showed tendency to worse initial neurological deficit (NIHSS 9 (3-13) vs. 4 (2-10); p = 0.06), higher rate of large vessel occlusion (LVO; 13/32 vs. 14/51; p = 0.21), had prolonged hospitalization (19.4 ± 17.7 vs. 9.7 ± 7 days; p = 0.003), had lower chance of functional independence (mRS≤2) (12/32 vs. 32/51; p = 0.02) and showed higher in-hospital mortality (10/32 vs. 6/51; p = 0.02). In COVID-19 AIS patients, LVO was more common with COVID-19 pneumonia than without (55.6% vs. 23.1%; p = 0.139). CONCLUSION: COVID-19-related AIS carries a worse prognosis. COVID-19 with pneumonia seems to be associated with a higher rate of LVO.

Two-Year observational study of autonomic skin function in patients with Parkinson's disease compared to healthy individuals.

BACKGROUND AND PURPOSE: We characterized autonomic pilomotor and sudomotor skin function in early Parkinson's disease (PD) longitudinally. METHODS: We enrolled PD patients (Hoehn and Yahr 1-2) and healthy controls from movement disorder centers in Germany, Hungary, and the United States. We evaluated axon-reflex responses in adrenergic sympathetic pilomotor nerves and in cholinergic sudomotor nerves and assessed sympathetic skin response (SSR), predominantly parasympathetic neurocardiac function via heart rate variability, and disease-related symptoms at baseline, after 2 weeks, and after 1 and 2 years. CLINICALTRIALS: gov: NCT03043768. RESULTS: We included 38 participants: 26 PD (60% females, aged 62.4 ± 7.4 years, mean ± SD) and 12 controls (75% females, aged 59.5 ± 5.8 years). Pilomotor function was reduced in PD compared to controls at baseline when quantified via spatial axon-reflex spread (78 [43-143], median [interquartile range] mm2 vs. 175 [68-200] mm2 , p = 0.01) or erect hair follicle count in the axon-reflex region (8 [6-10] vs. 11 [6-16], p = 0.008) and showed reliability absent any changes from baseline to Week 2 (p = not significant [ns]). Between-group differences increased over the course of 2 years (p < 0.05), although no decline was observed within groups (p = ns). Pilomotor impairment in PD correlated with motor symptoms (rho = -0.59, p = 0.017) and was not lateralized (p = ns). Sudomotor axon-reflex and neurocardiac function did not differ between groups (p = ns), but SSR was reduced in PD (p = 0.0001). CONCLUSIONS: Impairment of adrenergic sympathetic pilomotor function and SSR in evolving PD is not paralleled by changes to cholinergic sudomotor function and parasympathetic neurocardiac function, suggesting a sympathetic pathophysiology. A pilomotor axon-reflex test might be useful to monitor PD-related pathology.

A Rare Case of Histopathologically Confirmed Creutzfeldt-Jakob Disease from Romania, Long Route to Diagnosis-Case Report and an Overview of the Romanian CJD Situation.

Creutzfeldt-Jacob disease is a progressive and ultimately fatal disease, representing one of the most common forms of prion diseases. It is a rare pathology presenting with various symptomatology, and the fact that a definite diagnosis can be obtained solely by neuropathological techniques makes it hard to recognize and diagnose. Here we present the clinical and neuropathological features of a 72-year-old woman, who originally presented in a county hospital, then, along with the disease progression, got transferred to a university center in Romania, where CJD-specific tests are rarely performed, and ultimately was diagnosed with the help of international collaboration. The purpose of this case report and review is to summarize the Romanian CJD situation until the present day, to place the Romanian CJD epidemiology in an Eastern European context, and to highlight the diagnostic options and possibilities for clinical practitioners. We would also like to draw attention to the need for a national surveillance system. By presenting the patient's route in Romania from the first presentation to diagnosis, we would like to emphasize the importance of interdisciplinary and international collaboration, by which we managed to cross the regional diagnostic boundaries and create a possible diagnostic pathway for future cases.

Ten-year trends of the characteristics in patients with advanced Parkinson's disease at the time of intestinal gel therapy introduction / Az intestinalis gél bevezetésekor rögzített jellemzok tízéves változásai elorehaladott Parkinson-kóros betegekben

Introduction: Parkinson's disease is a neurodegenerative disease, the symptoms of which can be treated reasonably well; however, therapeutic recommendations need to be refined based on the observations from everyday practice. Objective: We aimed to analyze the extent by which published expert recommendations were reflected in the manage-ment of patients with advanced Parkinson's disease, prior to the introduction of the intestinal gel. Method: Data from patients treated with levodopa-carbidopa intestinal gel were retrospectively examined. The period from 2011 to 2021 was divided into two five-year periods, prior and after the usage of the 5-2-1 rule in clinical decision-making. Results: Levodopa-carbidopa intestinal gel treatment was initiated in 150 patients during the study period. In the second five-year period, the mean age of the patients was lower and the time from diagnosis was shorter. Also, there were significantly fewer patients with peak-dose dyskinesias (p = 0.02), biphasic dyskinesias (p<0.001), and early morning akinesias (p = 0.02). Furthermore, in the last five years of the study, fewer patients were affected by delayed on (p = 0.03), no on (p = 0.02), and freezing (p = 0.01). The mean score measured on the Hoehn-Yahr scale was also lower in the second period, while the mean MMSE score was higher (p<0.001). Daily doses of levodopa were higher (p<0.01) in the second period, but with similar dosing frequency. Conclusion: Our retrospective analysis of trends during a ten-year period revealed that, in the second five-year period, levodopa-carbidopa intestinal gel was started in advanced Parkinson's disease patients with a significantly better physical and cognitive state. Compared to expert recommendations, our patients still had a more severe clinical pic -ture at the start of device-aided therapy, but acceptance of this invasive method has improved both for patients and for general practitioners and neurologists.

Levodopa-Carbidopa Intestinal Gel in Advanced Parkinson's Disease: Observations and Dilemmas after 10 Years of Real-Life Experience.

Advanced Parkinson's disease (APD) cannot be treated efficiently using the classical medications however, in recent decades invasive therapeutical methods were implemented and confirmed as effective. One of these methods makes it possible to continue the levodopa (LD) supplementation as a gel administered directly into the upper intestine. However, there are a number of unanswered questions regarding this method. Therefore, we retrospectively analyzed a 10-year period of selected patients that were treated with levodopa/carbidopa intestinal gel (LCIG). We included all APD patients with motor fluctuations and dyskinesia at presentation. LCIG treatment was started in 150 patients: on average these patients received LD for 10.6 ± 4.4 years with a frequency of 5.2 ± 1.0/day until the introduction of LCIG. The estimated and the real LCIG dose differed significantly (mean: 1309 ± 321 mg vs. 1877 ± 769 mg). The mean duration of LCIG administration was 19.8 ± 3.6 h, but in a number of 62 patients we had to administer it for 24 h, to maximize the therapeutic benefit. A carefully and individually adjusted LCIG treatment improves the quality of life of APD patients, but questions remain unresolved even after treating a large number of patients. It is important to share the ideas and observations based on the real-life experience related to the optimal timing, the appropriate dose and duration of administration of the LCIG.

Effect of continuing versus stopping pre-stroke antihypertensive agents within 12 h on outcome after stroke: A subgroup analysis of the efficacy of nitric oxide in stroke (ENOS) trial.

BACKGROUND: It is not known whether to continue or temporarily stop existing antihypertensive drugs in patients with acute stroke. METHODS: We performed a prospective subgroup analysis of patients enrolled into the Efficacy of Nitric Oxide in Stroke (ENOS) trial who were randomised to continue vs stop prior antihypertensive therapy within 12 h of stroke onset. The primary outcome was functional outcome, assessed with the modified Rankin Scale at 90 days by observers blinded to treatment assignment, and analysed with ordinal logistic regression. FINDINGS: Of 4011 patients recruited into ENOS from 2001 to 2014, 2097 patients were randomised to continue vs stop prior antihypertensive treatment, and 384 (18.3%, continue 185, stop 199) were enrolled within 12 h of ictus: mean (SD) age 71.8 (11.8) years, female 193 (50.3%), ischaemic stroke 342 (89.1%) and total anterior circulation syndrome 114 (29.7%). As compared with stopping, continuing treatment within 12 h of onset lowered blood pressure by 15.5/9.6 mmHg (p<0.001/<0.001) by 7 days, shifted the modified Rankin Scale to a worse outcome by day 90, adjusted common odds ratio (OR) 1.46 (95% CI 1.01-2.11), and was associated with an increased death rate by day 90 (hazard ratio 2.17, 95% CI 1.24-3.79). Other outcomes (disability - Barthel Index, quality of life - EQ-visual analogue scale, cognition - telephone mini-mental state examination, and mood - Zung depression scale) were also worse with continuing treatment. INTERPRETATION: In this pre-specified subgroup analysis of the large ENOS trial, continuing prior antihypertensive therapy within 12 h of stroke onset in a predominantly ischaemic stroke population was unsafe with worse functional outcome, disability, cognition, mood, quality of life and increased death. Future studies assessing continuing or stopping prior antihypertensives in the context of thrombectomy are awaited.

Management Challenges of Severe, Complex Dyskinesia. Data from a Large Cohort of Patients Treated with Levodopa-Carbidopa Intestinal Gel for Advanced Parkinson's Disease.

BACKGROUND: In the advanced stages of Parkinson's disease (APD), complex forms of dyskinesia may severely impair the patient's quality of life. OBJECTIVE: In the present study, we aimed to analyze the evolution under LCIG therapy of the most important motor fluctuations and complex disabling dyskinesias, including diphasic dyskinesia. METHODS: In this retrospective study, we analyzed the characteristics of patients with APD who had at least 30 min of diphasic dyskinesia (DID) in 3 consecutive days, were considered responders and were treated with LCIG in our clinic. Patients were evaluated before and after PEG and at 6, 12 and 18 months, when the changes in the therapy were recorded, and they completed a 7-point Global Patient Impression of Improvement (PGI-I) scale. RESULTS: Forty patients fulfilled the inclusion criteria-out of which, 34 performed all visits. There was a substantial difference between the calculated and real LCIG (1232 ± 337 mg vs. 1823 ± 728 mg). The motor fluctuations and most dyskinesias improved significantly after starting LCIG, but an increasing number of patients needed longer daily administrations of LCIG (24 instead of 16 h). CONCLUSIONS: Patients with APD with complex dyskinesias must be tested in dedicated hospitals, and they need a special therapeutic approach. The properly adapted LCIG treatment regarding the dose and time of administration completed with well-selected add-on medication should offer improvement for patients who want to or can only choose this DAT vs. others.

Decision-making and duration to accept device-aided therapy in advanced Parkinson's disease / Döntési szempontok és az eszközös terápia elfogadásához szükséges ido elorehaladott Parkinson-kórban.

Összefoglaló. Bevezetés: Az elorehaladott Parkinson-kór bizonyos fázisában a motoros komplikációk már nem befolyásolhatók hatékonyan a hagyományos orális, illetve transdermalis gyógyszerekkel. Ilyenkor meg kell fontolni, komplex felmérési és döntési folyamatot követoen, az invazív eszközös terápiák bevezetését. Célkituzés: A döntéshozatal és a fontosabb klinikai paraméterek elemzése levodopa-karbidopa intestinalis géllel kezelt betegeinknél az elfogadás idotartamának függvényében. Módszer: Retrospektíven vizsgáltuk azon betegeink adatait, akiknél a marosvásárhelyi 2. Sz. Ideggyógyászati Klinikán 2011. június 1. és 2019. december 31. között vezettük be a levodopa-karbidopa intestinalis géllel történo terápiát. A kezelés elfogadásához szükséges idointervallum szerint két csoportot alkottunk: egy hónap vagy annál rövidebb, illetve egy hónapnál több ido az elso, célzott kivizsgálás és a tesztelés megkezdése között. Eredmények: A vizsgált idoszakban 163 betegnél teszteltük orrszondán a kezelés hatékonyságát, közülük 127 esetben történt meg a terápia véglegesítése. A döntéshozatal 56 betegnél egy hónap vagy annál rövidebb idot, míg 71 betegnél egy hónapnál több idot igényelt. A dyskinesisek átlagos idotartamának szempontjából szignifikáns különbséget találtunk a két csoport között (3,1 ± 0,7 vs. 2,8 ± 0,8 óra, p = 0,02). Az eszközös terápia bevezetése elotti levodopa-átlagadag 821,5 ± 246,6 mg volt, naponta átlagosan 5-ször adagolva. A kiegészíto terápiák alkalmazási arányai: a dopaminagonisták 80,3%-ban, a katechol-O-metiltranszferáz-gátlók 62,2%-ban, illetve a monoaminoxidáz-B-gátlók 68,5%-ban. Az átlagos off idotartam 4,7 ± 1,1 óra volt, és 85 betegünknél tapasztaltunk 2,9 ± 0,8 óra átlag-idotartamú dyskinesist. Következtetés: Hamarabb fogadják el az eszközös terápiát azok az elorehaladott Parkinson-kóros betegek, akiknek hosszabb idotartamú a napi dyskinesisük, illetve régebbi a betegségük. A terápiás irányelvek gyakorlatba ültetésekor figyelembe kell venni a helyi sajátosságokat: a kiegészíto gyógyszerekhez, illetve az eszközös terápiákhoz való hozzáférést. Orv Hetil. 2021; 162(21): 839-847. INTRODUCTION: In advanced stages of Parkinson's disease, motor complications cannot be effectively controlled with conventional therapies. In such cases, the complex assessment and decision-making process that leads to device-aided therapies should be considered. OBJECTIVE: To analyze the decision-making and key clinical parameters, as a function of duration of acceptance, patients treated with levodopa-carbidopa intestinal gel. METHOD: We retrospectively examined the data of patients who started levodopa-carbidopa intestinal gel therapy at the 2nd Department of Neurology Târgu Mures, between 1 June 2011 and 31 December 2019. Two groups were formed: less than one month and more than one month between the first targeted examination and the start of testing. RESULTS: Therapeutic efficiency was tested with nasal tube on 163 patients, out of whom 127 patients remained on treatment. Decision-making took one month or less for 56 patients and more than a month for 71 patients. Duration of dyskinesias was significantly different between the two groups (3.1 ± 0.7 vs 2.8 ± 0.8 hours, p = 0.02). Mean dose of levodopa prior to the introduction of device-aided therapy was 821.5 ± 246.6 mg, administered 5 times daily. Dopamine agonists were used in 80.3%, catechol-O-methyltransferase inhibitors in 62.2%, and monoamine oxidase-B inhibitors in 68.5% of cases. The mean off-time was 4.7±1.1 hours and data from 85 patients showed 2.9 ± 0.8 hours of dyskinesia. CONCLUSION: Device-aided therapy is adopted sooner by patients with advanced Parkinson's disease with longer disease duration and more dyskinesias. Local specificities, such as access to add-on medication and device-aided therapies, must be taken into account when implementing therapeutic guidelines. Orv Hetil. 2021; 162(21): 839-847.

Relationship between nitrate headache and outcome in patients with acute stroke: results from the efficacy of nitric oxide in stroke (ENOS) trial.

INTRODUCTION: Nitrate-induced headache is common and may signify responsive cerebral vasculature. We assessed the relationship between nitrate headache and outcome in patients with acute stroke. MATERIALS AND METHODS: Patients were those randomised to glyceryl trinitrate (GTN) versus no GTN in the efficacy of nitric oxide in stroke trial. Development of headache by end of treatment (day 7), and functional outcome (modified Rankin Scale, primary outcome) at day 90, were assessed. Analyses are adjusted for baseline prognostic factors and give OR and mean difference (MD) with 95% CI. RESULTS: In 4011 patients, headache was more common in GTN than control (360, 18.0% vs 170, 8.5%; p<0.001). Nitrate-related headache was associated with: younger age, female sex, higher diastolic blood pressure, non-total anterior circulation syndrome, milder stroke and absence of dysphasia (p<0.05). Nitrate headache was not associated with improved functional outcome (OR 0.90, 95% CI 0.73 to 1.10, p=0.30) or death (day 90) (HR 0.64, 95% CI 0.40 to 1.02, p=0.062), but reduced death or deterioration (day 7) (OR 0.45, 95% CI 0.25 to 0.82), death in hospital (OR 0.44, 95% CI 0.22 to 0.88) and improved activities of daily living (Barthel index, MD 3.7, 95% CI 0.3 to 7.1) and cognition (telephone interview cognitive screen, MD 2.0, 95% CI 0.7 to 3.3) (day 90). Non-nitrate headache was not associated with death, disability or cognition. DISCUSSION AND CONCLUSION: Development of a nitrate headache by day 7 after stroke may be associated with improved activities of daily living and cognitive impairment at day 90, which was not seen with non-nitrate headache.

The prevalence of psychiatric symptoms before the diagnosis of Parkinson's disease in a nationwide cohort: A comparison to patients with cerebral infarction.

OBJECTIVES: Psychiatric symptoms (PS) can be non-motor features in Parkinson's disease (PD) which are common even in the prodromal, untreated phase of the disease. Some PS, especially depression and anxiety recently became known predictive markers for PD. Our objective was to explore retrospectively the prevalence of PS before the diagnosis of PD. METHODS: In the framework of the Hungarian Brain Research Program we created a database from medical and medication reports submitted for reimbursement purposes to the National Health Insurance Fund in Hungary, a country with 10 million inhabitants and a single payer health insurance system. We used record linkage to evaluate the prevalence of PS before the diagnosis of PD and compared that with patients with ischemic cerebrovascular lesion (ICL) in the period between 2004-2016 using ICD-10 codes of G20 for PD, I63-64 for ICL and F00-F99 for PS. We included only those patients who got their PD, ICL and psychiatric diagnosis at least twice. RESULTS: There were 79 795 patients with PD and 676 874 patients with ICL. Of the PD patients 16% whereas of those with ischemic cerebrovascular lesion 9.7% had a psychiatric diagnosis before the first appearance of PD or ICL (p<0.001) established in psychiatric care at least twice. The higher rate of PS in PD compared to ICL remained significant after controlling for age and gender in logistic regression analysis. The difference between PD and ICL was significant for Mood disorders (F30-F39), Organic, including symptomatic, mental disorders (F00-F09), Neurotic, stress-related and somatoform disorders (F40-F48) and Schizophrenia, schizotypal and delusional disorders (F20-F29) diagnosis categories (p<0.001, for all). DISCUSSION: The higher rate of psychiatric morbidity in the premotor phase of PD may reflect neurotransmitter changes in the early phase of PD.

Levodopa-Carbidopa Intestinal Gel Infusion Therapy Discontinuation: A Ten-Year Retrospective Analysis of 204 Treated Patients.

BACKGROUND: Parkinson's disease (PD) is the second most common progressive neurodegenerative disease. In the advanced stages, the continuous delivery of levodopa (LD) as levodopa-carbidopa intestinal gel (LCIG) has demonstrated significant improvement of motor and nonmotor complications and improvement of the patients' quality of life (QoL). Despite the growing global experience with this treatment, anumber of unsolved practical issues remain, and currently, the data on the reasons that can lead to the discontinuation of LCIG are scarce. OBJECTIVE: In the present study, we aimed to analyze the causes that led to the discontinuation of LCIG therapy. METHODS: In this retrospective study, after 10 years of experience with LCIG as a therapeutic option in advanced PD, we analyzed the data of all dropout cases among the 204 patients that initiated LCIG therapy in two Romanian centers. RESULTS: Of the 204 patients enrolled, 43 patients dropped out. Disease duration until LCIG infusion was significantly longer (11.67±4.98 vs 9.44±3.44) and the overall clinical picture more sever (both regarding motor symptoms and cognitive decline) in dropout patients (compared to patients who continued treatment). The dropout patients also presented significant differences regarding the incidence of polyneuropathy (32.5% vs 11.18%). The main cause of discontinuation was death. CONCLUSION: The causes of discontinuation from LCIG therapy in Romanian patients are similar to those from other centers; however, the rate of dropouts is somewhat lower. The clinician's experience in selecting and treating the patients in advanced stages of PD can increase therapeutic adherence. Also, the presence of a well-trained caregiver along with the availability of a proper aftercare system is mandatory for maintaining the long-term benefits of the therapy and the overall best outcome possible. Targeted prospective studies are needed to confirm whether a more severe stage of the disease and cognitive impairment at the time of initiation, respectively, the association of polyneuropathy can be considered as predictive factors for dropout.

Imaging markers of small vessel disease and brain frailty, and outcomes in acute stroke.

OBJECTIVE: To assess the association of baseline imaging markers of cerebral small vessel disease (SVD) and brain frailty with clinical outcome after acute stroke in the Efficacy of Nitric Oxide in Stroke (ENOS) trial. METHODS: ENOS randomized 4,011 patients with acute stroke (<48 hours of onset) to transdermal glyceryl trinitrate (GTN) or no GTN for 7 days. The primary outcome was functional outcome (modified Rankin Scale [mRS] score) at day 90. Cognition was assessed via telephone at day 90. Stroke syndrome was classified with the Oxfordshire Community Stroke Project classification. Brain imaging was adjudicated masked to clinical information and treatment and assessed SVD (leukoaraiosis, old lacunar infarcts/lacunes, atrophy) and brain frailty (leukoaraiosis, atrophy, old vascular lesions/infarcts). Analyses used ordinal logistic regression adjusted for prognostic variables. RESULTS: In all participants and those with lacunar syndrome (LACS; 1,397, 34.8%), baseline CT imaging features of SVD and brain frailty were common and independently associated with unfavorable shifts in mRS score at day 90 (all participants: SVD score odds ratio [OR] 1.15, 95% confidence interval [CI] 1.07-1.24; brain frailty score OR 1.25, 95% CI 1.17-1.34; those with LACS: SVD score OR 1.30, 95% CI 1.15-1.47, brain frailty score OR 1.28, 95% CI 1.14-1.44). Brain frailty was associated with worse cognitive scores at 90 days in all participants and in those with LACS. CONCLUSIONS: Baseline imaging features of SVD and brain frailty were common in lacunar stroke and all stroke, predicted worse prognosis after all acute stroke with a stronger effect in lacunar stroke, and may aid future clinical decision-making. IDENTIFIER: ISRCTN99414122.

Linking Individual Patient Data to Estimate Incidence and Prevalence of Parkinson's Disease by Comparing Reports of Neurological Services and Pharmacy Prescription Refills at a Nationwide Level.

Objectives: We set forth to estimate the number of those with Parkinson's disease (PD) in Hungary, a country with a single-payer health insurance system covering 10 million inhabitants. Methods: We analyzed all hospital and outpatient reports from neurological services and pharmacy reports of prescription refills. We cross-checked clinically administered diagnosis of PD with prescription refills of antiparkinsonian medications using record linkage. We used the ICD-10 code of G20 in any diagnostic category to find all cases with possible PD. For case certification those patients were considered to have PD who were recorded with G20 code in at least 2 calendar years. For a more conservative estimation we determined the number of those who also refilled antiparkinsonian medication. Results: Between 2010 and 2012 there were 46,383 subjects with certified PD by clinical criteria. Crude and age-standardized incidence were 49/100,000/year (95% CI: 45-53), and 56/100,000/year (95% CI: 51-60). Crude and age standardized prevalence rates were 404/100,000 (95% CI: 392-416) and 471/100,000 (95% CI: 456-485). Of all clinically certified PD patients 72% refilled antiparkinsonian medications. Discussion: The incidence and prevalence of PD in Hungary is higher than earlier estimates, which should be considered in organizing healthcare services for this patient group.

[Dopamine agonists in Parkinson's disease therapy - 15 years of experience of the Neurological Clinics from Tîrgu Mureș. A cross-sectional study]. / A dopaminagonisták jelentosége a Parkinson-kór kezelésében a marosvásárhelyi ideggyógyászati klinikák 15 éves gyakorlatában - keresztmetszeti vizsgálat.

BACKGROUND AND PURPOSE: There is relatively few data regarding the usage of dopaminagonists for the treatment of Parkinson's disease; furthermore, there are no publications regarding Central- and Eastern-European countries. The aim of the study was to evaluate the use of dopamine agonists as a therapeutic option amongst Parkinson's disease patients admitted to the Neurological Clinics of Tîrgu Mures during the last 15 years. METHODS: In our study we investigated the data of all Parkinson's patients treated at our clinics between the 1st of January 2003 and the 31st of December 2017. We analyzed the particularities of dopamine agonists' usage based on the therapeutic recommendations from the final report of these patients. Regarding time since the diagnosis, we divided the patients in two groups: less than or equal to 5 years and more than 5 years. RESULTS: During the studied period a total of 2379 patients with Parkinson's disease were treated at the Clinics. From the 1237 patients with disease duration under 5 years 665 received dopamine agonists: 120 as monotherapy, 83 together with monoamine oxidase inhibitors and in 234 cases associated with levodopa. The remaining 228 patients were treated with a triple combination of levodopa, dopamine agonists and monoamine oxidase inhibitors. In patients suffering from Parkinson's disease for more than 5 years, in 364 cases out of 653 a dopamine agonist was part of the therapy. CONCLUSION: The usage of dopamine agonists was similar to the data presented in other studies. We consider that clinicians treating the disease should, with the necessary prudence, use the available and recommended dopamine agonist with the utmost courage to their maximum therapeutic potential.

Cardiac dysautonomia in depression - heart rate variability biofeedback as a potential add-on therapy.

Depressive disorders are among the most important health problems and are predicted to constitute the leading cause of disease burden by the year 2030. Aside significant impact on quality of life, psychosocial well-being and socioeconomic status of affected patients, depression is associated with impaired cardiovascular health and increased mortality. The link between affective and cardiovascular disease has largely been attributed to dysregulation of the autonomic nervous system resulting in a chronic shift toward increased sympathetic and decreased parasympathetic activity and, consecutively, cardiac dysautonomia. Among proposed surrogate parameters to capture and quantitatively analyze this shift, heart rate variability (HRV) and baroreflex sensitivity have emerged as reliable tools. Attenuation of these parameters is frequently seen in patients suffering from depression and is closely linked to cardiovascular morbidity and mortality. Therefore, diagnostic and therapeutic strategies were designed to assess and counteract cardiac dysautonomia. While psychopharmacological treatment can effectively improve affective symptoms of depression, its effect on cardiac dysautonomia is limited. HRV biofeedback is a non-invasive technique which is based on a metronomic breathing technique to increase parasympathetic tone. While some small studies observed beneficial effects of HRV biofeedback on dysautonomia in patients with depressive disorders, larger confirmatory trials are lacking. We reviewed the current literature on cardiac dysautonomia in patients suffering from depression with a focus on the underlying pathophysiology as well as diagnostic workup and treatment.

It is safe to use transdermal glyceryl trinitrate to lower blood pressure in patients with acute ischaemic stroke with carotid stenosis.

Background: There is concern that blood pressure (BP) lowering in acute stroke may compromise cerebral perfusion and worsen outcome in the presence of carotid stenosis. We assessed the effect of glyceryl trinitrate (GTN) in patients with carotid stenosis using data from the Efficacy of Nitric Oxide in Stroke (ENOS) Trial. Methods: ENOS randomised 4011 patients with acute stroke and raised systolic BP (140-220 mm Hg) to transdermal GTN or no GTN within 48 hours of onset. Those on prestroke antihypertensives were also randomised to stop or continue their medication for 7 days. The primary outcome was the modified Rankin Scale (mRS) at day 90. Ipsilateral carotid stenosis was split: <30%; 30-<50%; 50-<70%; ≥70%. Data are ORs with 95% CIs adjusted for baseline prognostic factors. Results: 2023 (60.5%) ischaemic stroke participants had carotid imaging. As compared with <30%, ≥70% ipsilateral stenosis was associated with an unfavourable shift in mRS (worse outcome) at 90 days (OR 1.88, 95% CI 1.44 to 2.44, p<0.001). Those with ≥70% stenosis who received GTN versus no GTN had a favourable shift in mRS (OR 0.56, 95% CI 0.34 to 0.93, p=0.024). In those with 50-<70% stenosis, continuing versus stopping prestroke antihypertensives was associated with worse disability, mood, quality of life and cognition at 90 days. Clinical outcomes did not differ across bilateral stenosis groups. Conclusions: Following ischaemic stroke, severe ipsilateral carotid stenosis is associated with worse functional outcome at 90 days. GTN appears safe in ipsilateral or bilateral carotid stenosis, and might improve outcome in severe ipsilateral carotid stenosis.

Therapeutic strategies in the early stages of Parkinson's disease: a cross-sectional evaluation of 15 years' experience with a large cohort of Romanian patients.

INTRODUCTION: In patients older than 70 years there is no valid alternative to progressively introduced substitution therapy. The antiparkinsonian drugs introduced in the last decade to treat Parkinson's disease, especially in its early phases, promised a comparable efficacy in reducing symptoms to levodopa. In younger patients and/or patients with mild symptoms we hoped to delay the motor complications by postponing the start of levodopa therapy. While these assumptions may not be true for all patients, probably the most important current challenge is the optimal starting moment of levodopa therapy. The aim of the study was to analyze the therapeutical choices during the early phase of Parkinson's disease in the Neurological Departments of Târgu Mures¸ County Hospital. MATERIALS AND METHODS: We examined data obtained from hospitalized Parkinson's disease patients during a 15-year period. According to the duration of the disease we split the patients into two groups, patients with Parkinson's disease for less than or equal to 5 years and patients with disease duration longer than 5 years, and then analyzed only the former group. RESULTS: During the examined period, 2,379 patients with Parkinson's disease were hospitalized, and 1,237 patients had a disease duration shorter than 5 years. In this group, 18 patients had monoamine oxidase inhibitor monotherapy. Also, 665 patients received dopamine agonists, in 120 cases as monotherapy and in 83 patients associated with monoamine oxidase inhibitors. In 521 patients we found only levodopa treatment. A further 481 patients received combined therapy (levodopa with dopamine agonists and/or monoamine oxidase inhibitors). CONCLUSION: Treatment strategies for the early stages of Parkinson's disease in our group were comparable to results from other studies. However, the authors feel that neurologists should use levodopa-sparing drugs with greater courage. Furthermore, if the clinical context is appropriate, physicians should combine substitution therapy with other antiparkinsonian drugs in order to reduce levodopa doses.
