[Background - The levodopa/carbidopa intestinal gel (LCIG) therapy can improve the severe fluctuations associated with advanced Parkinson’s disease (PD). Our aim was to assess the improvement in the health related quality of life of PD patients treated with LCIG at University of Pécs. Methods - Eight PD patients were evaluated (age: 68.1±4.4 years, disease duration: 14,5±6,2 years, duration of fluctuations: 8.9±3.1 years). Before the initiation of LCIG treatment and 6 and 12 months later, the health-related quality of life (PDQ-39 and EQ-5D-5L), severity of PDrelated symptoms (MDS-UPDRS, Hoehn-Yahr Scale, Clinical Global Improvement - Severity) and major non-motor symptoms (PD Sleep Scale 2nd version: PDSS-2, Epworth Scale and Beck Depression Inventory: BDI) were assessed. Results - Health-related quality life improved after LCIG treatment measured by both EQ-5D-5L (from 0.257 to 0.662, p=0.009) and PDQ-39 (from 34 to 26 points, p=0.038). Meanwhile PD-related symptoms (MDS-UPDRS total score: from 105 points to 68 points, p<0.05) sleep quality (PDSS-2: from 25 to 22 points, p<0.05), daytime sleepiness (Epworth: from 12 to 7 points, p<0.05) and depression (BDI: from 20 to 15 points, p<0.05) also improved. Median ON time improved form 4.5 hours to 10.0 hours; whereas, the OFF time decreased from 4.5 to 0.5 hours (p<0.05). Conclusion - Both the quality of life and the clinical features of PD can be improved by LCIG treatment in advanced PD.]

[Natalizumab therapy, 2013]

KARÁCSONY Mária, BENCSIK Krisztina, VÉCSEI László

[Multiple sclerosis (MS) is the most common chronic disease of the central nervous system in young adults. No curative therapy is known. Currently, six drugs are available that can reduce the activity of MS. The first-line drugs can completely reduce the activity of the disease in nearly two-thirds of the patients. In the remainder, who suffer from breakthrough disease, the condition of the patient worsens, and secondline therapies must be used. The second-line drug natalizumab exhibits almost double efficacy of the first-line drugs, but also have less favourable adverse effects. As a severe side-effect for instance, natalizumab carries the risk of the development of progressive multifocal leucoencephalopathy (PML), caused by a polyoma virus, the JC virus. There are three major risk factors for PML: an anti-JCV antibody status, a long duration of natalizumab treatment and prior immunosuppressant therapy. The lowest-risk group (1:14 286) comprises of patients who are anti-JCV antibody-negative, in whom the prior immunosuppressant use and duration of natalizumab therapy do not influence the risk of PML. With no prior immunosuppressant treatment, the incidence of PML increases to 1 in 192 patients after 2 years among those who are anti-JCV antibody-positive. These data may lead the physician to decide to discontinue natalizumab treatment. The half-life of natalizumab is three months; during this time other therapies can not be administered and the patients encounter the rebound effect: as the patients receiving natalizumab therapy displayed a high disease activity before treatment, the rebound effect can lead to relapses. After the termination of natalizumab secondline disease-modifying therapy with fingolimod may be introduce; no PML cases occur in response to fingolimod treatment. In the large majority of patients taking natalizumab who do not develop PML, this drug is highly effective and can prevent the progression of MS. The benefit of therapy and the risk of PML must be considered on an individual basis, with regard to the disease activity, the progression and the MRI activity, before natalizumab therapy is implemented.]

[Depression in Parkinson’s disease]

RIHMER Zoltán, GONDA Xénia, DÖME Péter

[The prevalence of major and minor depression in Parkinson’s disease is around 30-40% but, unfortunately, depression remains frequently underrecognized and often undertreated. However, recognition and appropriate treatment of depression in patients with Parkinson’s disease is essential for improving the cross-sectional picture and longitudinal course. This review focuses on the epidemiology, pathophysiology and different treatment modalities of depression in Parkinson’s disease.]

[Maybe it hurts more than you think! - Neonatal pain]

MIKOS Borbála

[Neonatal pain is often undertreated. This is based on the assumption that because of the immature nervous system and the lack of the myelinisation preterm and newborn does not feel pain. It is confirmed by a number of articles that the fetus and neonate can experience and respond to painful events. This publication gives a brief overview of the ontogeny of the pain, short-and long-term postnatal consequences, as well as the perception of the possibility of a particularly frail child population: premature infants and neonates, based on animal and human studies.]

Retinal morphological changes during the two years of follow-up in Parkinson’s disease

ATUM Mahmut, DEMIRYÜREK Enes Bekir

The study aims to investigate the relationship between the progression of idiopathic Parkinson’s disease (IPD) and retinal morphology. The study was carried out with 23 patients diagnosed with early-stage IPD (phases 1 and 2 of the Hoehn and Yahr scale) and 30 age-matched healthy controls. All patients were followed up at least two years, with 6-month intervals (initial, 6th month, 12th month, 18th month, and 24th month), and detailed neurological and ophthalmic examinations were performed at each follow-up. Unified Parkinson’s Disease Rating Scale part III (UPDRS Part III) scores, Hoehn and Yahr (H&Y) scores, best-corrected visual acuity (BCVA), intraocular pressure (IOP) measurement, central macular thickness (CMT) and retinal nerve fiber layer (RNFL) thickness were analyzed at each visit. The average age of the IPD and control groups was 43.96 ± 4.88 years, 44.53 ± 0.83 years, respectively. The mean duration of the disease in the IPD group was 7.48 ± 5.10 months at the start of the study (range 0-16). There was no statistically significant difference in BCVA and IOP values between the two groups during the two-year follow-up period (p> 0.05, p> 0.05, respectively). Average and superior quadrant RNFL thicknesses were statistically different between the two groups at 24 months and there was no significant difference between other visits (p=0.025, p=0.034, p> 0.05, respectively). There was no statistically significant difference in CMT between the two groups during the follow-up period (p> 0.05). Average and superior quadrant RNFL thicknesses were significantly thinning with the progression of IPD.

[Background and purpose - Data on the disease burden of Duchenne Muscular Dystrophy are scarce in Hungary. The aim of this study was to assess patients’ and their caregivers’ health related quality of life and healthcare utilisations. Methods - A cross sectional survey was performed as part of the European BURQOL-RD project. The EQ-5D-5L and Barthel Index questionnaires were applied, health care utilisations and patients’ informal carers were surveyed. Results - One symptomatic female carer, 50 children (boys 94%) and six adult patients (five males) participated in the study, the latter two subgroups were included in the analysis. The average age was 9.7 (SD=4.6) and 24.3 (SD=9.8) years, respectively. Median age at time of diagnosis was three years. The average EQ-5D score among children and adults was 0.198 (SD=0.417) and 0.244 (SD=0.322), respectively, the Barthel Index was 57.6 (SD=29.9) and 53.0 (SD=36.5). Score of satisfaction with healthcare (10-point Likert-scale) was mean 5.3 (SD=2.1) and 5.3 (SD=2.9). 15 children were hospitalised in the past 12 months for mean 12.9 (SD=24.5) days. Two patients received help from professional carer. 25 children (mean age 11.1, SD=4.4 years) were helped/supervisied by principal informal carer (parent) for mean 90.1 (SD=44.4) hours/week and further family members helped in 21 cases. Correlation between EQ-5D and Barthel Index was strong and significant (0.731; p<0.01) as well as with informal care time (-0.770; p<0.01), but correlation with satisfaction with health care was not significant (EQ-5D: 0.241; Barthel Index: 0.219; informal care: -0.142). Conclusion - Duchenne muscular dystrophy leads to a significant deterioration in the quality of life of patients. Parents play outstanding role in the care of affected children. This study is the first in the Central and Eastern European region that provides quality of life data in this rare disease for further health economic studies.]

[The quality of life of the cluster headache patients during the active phase of the headache]

DIÓSSY Mária, BALOGH Eszter, MAGYAR Máté, GYÜRE Tamás, CSÉPÁNY Éva, BOZSIK György, ERTSEY Csaba

[Introduction - Cluster headache (CH), which affects 0.1% of the population, is one of the most painful human conditions: despite adequate treatment, the frequent and severe headaches cause a significant burden to the patients. According to a small number of previous studies, CH has a serious negative effect on the sufferers’ quality of life (QOL). In the current study, we set out to examine the quality of life of the CH patients attending our outpatient service between 2013 and 2016, using generic and headache-specific QOL instruments. Methods - A total of 42 CH patients (16 females and 26 males; mean age: 39.1±13.5 years) completed the SF-36 generic QOL questionnaire and the headache- specific CHQQ questionnaire (Comprehensive Headache- related Quality of life Questionnaire), during the active phase of their headache. Their data were compared to those of patients suffering from chronic tension type headache (CTH) and to data obtained from controls not suffering from significant forms of headache, using Kruskal-Wallis tests. Results - During the active phase of the CH, the patients’ generic QOL was significantly worse than that of normal controls in four of the 8 domains of the SF-36 instrument. Apart from a significantly worse result in the ‘Bodily pain’ SF-36 domain, there were no significant differences between the CH patients’ and the CTH patients’ results. All the dimensions and the total score of the headache-specific CHQQ instrument showed significantly worse QOL in the CH group than in the CTH group or in the control group. Conclusion - Cluster headache has a significant negative effect on the quality of life. The decrease of QOL experienced by the patients was better reflected by the headache-specific CHQQ instrument than by the generic SF-36 instrument. ]

[Dopamine agonists in Parkinson’s disease therapy - 15 years of experience of the Neurological Clinics from Tîrgu Mureș. A cross-sectional study ]

SZÁSZ József Attila, CONSTANTIN Viorelia, MIHÁLY István, BIRÓ István, PÉTER Csongor, ORBÁN-KIS Károly, SZATMÁRI Szabolcs

[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.]

[The applicability of 123I-FP-CIT SPECT dopamine transporter imaging in clinical practice]

PERLAKI Gábor, SZEKERES Sarolta, JANSZKY József, DEZSŐ Dániel, ASCHERMANN Zsuzsanna, ZÁMBÓ Katalin, KOVÁCS Norbert

[The 123I-FP-CIT dopamine transporter SPECT imaging is a sensitive method to assess functional dopaminergic neuron terminals in the striatum. The method has also been available in Hungary for years. There are two main indications: (i) to help differentiate essential tremor from clinically uncertain Parkinsonism, including patients with early symptoms and (ii) to help differentiate dementia with Lewy bodies from Alzheimer’s disease. The aim of this paper is to review 123I-FP-CIT SPECT imaging based on international data/guidelines and our own experiences, thereby assisting nuclear medicine practitioners and neurologists.]
