[Association of body composition and mortality in patients on maintenance dialysis and on waitlist and after kidney transplantation]

UJSZÁSZI Ákos, KALANTAR-ZADEH Kamyar, MOLNÁR Miklós Zsolt

[Overweight [body mass index (BMI) = 25-30 kg/m2] and obesity (BMI ≥30 kg/m2) are epidemic in both developed and developing countries. Obesity has been recognized as risk factor for the development and progression of chronic kidney disease and is associated with increased cardiovascular risk and poor survival. Almost 2/3 of maintenance hemodialysis patients die within five years of commencing dialysis treatment. Although patients on the waitlist having less severe comorbidities than their non-listed counterparts, the death rate remains high while it can take years for an organ donation. In patients with end stage renal disease (ESRD) undergoing maintenance hemodialysis an “obesity paradox” has been consistently reported, i.e., a high BMI is incrementally associated with better survival. Overweight and obesity are highly prevalent in patients at the time of kidney transplantation. Indeed, most transplant centers in US may suspend wait-listing of obese patients with a BMI above 30 or 35 kg/m2 and refer them for weight reduction procedures such as bariatric surgery as a contingency for the transplant surgery. The effect of pre- and post-transplant obesity in kidney transplanted patients on long-term graft and patient survival has not been well established. We have reviewed and summarized salient recent data pertaining to body composition and clinical outcomes about the association of survival and body composition in transplant-waitlisted dialysis patients and kidney transplanted recipients. ]

[Antihypertensive therapy in patients with COPD - the significance of nebivolol]

FARSANG Csaba

[The occurrence of hypertension associated with chronic obstructive pulmonary disease (COPD) is increasing. Recognising COPD is important in order to choose the appropriate antihypertensive drugs. Anti-hypertensive drugs that can be used to treat patients with hypertension and COPD include diuretics, ACE-inhibitors, angioten-sine receptor blockers (AT1 receptor antagonists) and calcium antagonists, as well as cardioselective beta blockers, as these drugs decrease total and cardiovascular mortality. Of these agents, the importance of the most cardioselective one, nebivolol should be stressed, as this drug has no clinically significant effect on parameters of respiratory function, and, through its additional effects (namely by increasing the synthesis of NO), it has a beneficial effect on COPD-related deterioration of respiratory functions, haemodynamic alterations (cor pulmonale) and local factors that participate in the respiratory inflammation and endothelial dysfunction.]

[Genetics of isolated steroid-resistant nephrotic syndrome - results of the two decades around the turn of the millennium]

TORY Kálmán, KERTI Andrea, REUSZ György

[Childhood steroid-resistant nephrotic syndrome (SRNS) is a devastating clinical condition which progresses to end-stage renal disease in 30-40% of the cases after a follow up of 10 years. Based on its etiology, two forms can be distinguished, an immune and a genetic form. During the last two decades, mutations of ten genes - encoding mainly podocyte proteins - were identified in the latter group. As the treatment in the immune and genetic forms are different, and only the identification of the causative mutation can reliably distinguish them, it is important to be familiarized with the genotype-phenotype correlations. The aim of the present review is to summarize our current knowledge on the phenotypes linked to the identified genes.]

[Association between complications of percutaneous kidney biopsy and histological diagnosis ]

FISI Viktória, MAZÁK István, DEGRELL Péter, HALMAI Richárd, MOLNÁR Gergő A., FEHÉR Eszter, NÉMETH Kinga, PINTÉR István, KOVÁCS Tibor, WITTMANN István

[Background: Percutaneous renal biopsy is an essential tool in diagnosis and prognosis of renal diseases. It is well-known that this method has potential complications. The connection between complication occurrence related to renal biopsies and histological diagnoses of the biopsy specimen was analyzed in the present study. We also analyzed the distribution of diagnoses in our population. Methods: In this retrospective survey, 353 patients undergoing renal biopsy was studied. Biopsies were performed after marking the site of puncture with ultrasound imaging. Influence of diagnoses and clinical parameters on complications was evaluated. Results: We found a complication rate of 44.5%. In patients with diabetic nephropathy (likelihood ratio (LR) 0.44) or acute tubular necrosis (LR 0.38) a significantly lower rate of complications was found, while patients with thin basement membrane syndrome had more than 6-fold higher risk for evolvement of intrarenal haemorrhage. Patients with acute interstitial nephritis (LR 3.18) or vasculitis (LR 2.88) have a more than 2-fold risk for arteriovenous shunts while in patients with severe arteriosclerosis the occurrence of this complication was lower (LR 0.46). In rapidly progressive glomerulonephritis, arteriovenous shunts evolved also in a significantly higher rate. Conclusion: Patients with vasculitis, rapidly progressive glomerulonephritis, thin basement membrane syndrome or acute interstitial nephritis should be monitored more carefully after renal biopsy due to the significantly higher risk for complications. ]

[Advanced Parkinson’s disease characteristics in clinical practice: Results from the OBSERVE-PD study and sub-analysis of the Hungarian data]

TAKÁTS Annamária, ASCHERMANN Zsuzsanna, VÉCSEI László, KLIVÉNYI Péter, DÉZSI Lívia, ZÁDORI Dénes, VALIKOVICS Attila, VARANNAI Lajos, ONUK Koray, KINCZEL Beatrix, KOVÁCS Norbert

[The majority of patients with advanced Parkinson’s disease are treated at specialized movement disorder centers. Currently, there is no clear consensus on how to define the stages of Parkinson’s disease; the proportion of Parkinson’s patients with advanced Parkinson’s disease, the referral process, and the clinical features used to characterize advanced Parkinson’s disease are not well delineated. The primary objective of this observational study was to evaluate the proportion of Parkinson’s patients identified as advanced patients according to physician’s judgment in all participating movement disorder centers across the study. Here we evaluate the Hungarian subset of the participating patients. The study was conducted in a cross-sectional, non-interventional, multi-country, multi-center format in 18 countries. Data were collected during a single patient visit. Current Parkinson’s disease status was assessed with Unified Parkinson’s Disease Rating Scale (UPDRS) parts II, III, IV, and V (modified Hoehn and Yahr staging). Non-motor symptoms were assessed using the PD Non-motor Symptoms Scale (NMSS); quality of life was assessed with the PD 8-item Quality-of-Life Questionnaire (PDQ-8). Parkinson’s disease was classified as advanced versus non-advanced based on physician assessment and on questions developed by the Delphi method. Overall, 2627 patients with Parkinson’s disease from 126 sites were documented. In Hungary, 100 patients with Parkinson’s disease were documented in four movement disorder centers, and, according to the physician assessment, 50% of these patients had advanced Parkinson’s disease. Their mean scores showed significantly higher impairment in those with, versus without advanced Parkinson’s disease: UPDRS II (14.1 vs. 9.2), UPDRS IV Q32 (1.1 vs. 0.0) and Q39 (1.1 vs. 0.5), UPDRS V (2.8 vs. 2.0) and PDQ-8 (29.1 vs. 18.9). Physicians in Hungarian movement disorder centers assessed that half of the Parkinson’s patients had advanced disease, with worse motor and non-motor symptom severity and worse QoL than those without advanced Parkinson’s disease. Despite being classified as eligible for invasive/device-aided treatment, that treatment had not been initiated in 25% of these patients.]

Evaluation of anxiety, depression and marital relationships in patients with migraine

DEMIR Fıgen Ulku, BOZKURT Oya

Aim - The aim of this study was to evaluate the frequency and characteristics of attacks in patients with migraine, to determine the effects of anxiety or depressive symptoms, and to evaluate the marital relationships of patients with migraine. Method - Thirty patients who were admitted to the neurology outpatient clinic of our hospital between July 2018 and October 2018 and were diagnosed with migraine according to the 2013 International Headache Society (IHS) diagnostic criteria were included in this cross-sectional study. Age, sex, headache frequency and severity, depressive traits, marital satisfaction and anxiety status were examined. We used the Beck Depression Inventory (BDI), State-Trait Anxiety Inventory (STAI), Maudsley Marital Questionnaire (MMQ) and Visual Analogue Scale (VAS) for measuring relevant parameters. Results - The mean severity of migraine pain according to VAS scale was 6.93 ± 1.41 and the mean number of migraine attacks was 4.50 ± 4.24. The mean BDI score of the patients was 12.66 ± 8.98, the mean MMQ-M score was 19.80 ± 12.52, the mean MMQ-S score was 13.20 ± 9.53, the mean STAI-state score was 39.93 ± 10.87 and the mean STAI-trait score was 45.73 ± 8.96. No significant correlation was found between age, number of migraine attacks, migraine duration, migraine headache intensity, and BDI, STAI and MMQ scores (p>0.05). But there was a positive correlation between MMQ-S and scores obtained from the BDI and STAI-state scales (p<0.05). Conclusion - In this study more than half of the migraine patients had mild, moderate or severe depression. A positive correlation was found between sexual dissatisfaction and scale scores of depression and anxiety.

[Decisional collisions between evidence and experience based medicine in care of people with epilepsy]

RAJNA Péter

[Background – Based on the literature and his long-term clinical practice the author stresses the main collisions of evidence and experience based medicine in the care of people with epilepsy. Purpose – To see, what are the professional decisions of high responsibility in the epilepsy-care, in whose the relevant clinical research is still lacking or does not give a satisfactory basis. Methods – Following the structure of the Hungarian Guideline the author points the critical situations and decisions. He explains also the causes of the dilemmas: the lack or uncertainty of evidences or the difficulty of scientific investigation of the situation. Results – There are some priorities of experience based medicine in the following areas: definition of epilepsy, classification of seizures, etiology – including genetic background –, role of precipitating and provoking factors. These are able to influence the complex diagnosis. In the pharmacotherapy the choice of the first drug and the optimal algorithm as well as the tasks during the care are also depends on personal experiences sometimes contradictory to the official recommendations. Same can occur in the choice of the non-pharmacological treatments and rehabilitation. Discussion and conclusion – Personal professional experiences (and interests of patients) must be obligatory accessories of evidence based attitude, but for achieving the optimal results, in some situations they replace the official recommendations. Therefore it is very important that the problematic patients do meet experts having necessary experiences and also professional responsibility to help in these decisions. ]

[Assessment of environmental health and knowledge of silicosis among dental technicians]

LÁNG Anett, HIRDI Henriett Éva

[The aim of the study: The aim was to assess the health status of the Hungarian dental technicians and their knowledge of silicosis diseases. Methods: The survey was conducted in December 2017 - January 2018 through self-constructed online questionnaire among dental laboratory technicians in Budapest. Data were analysed with SPSS 22.0. Results: The survey was completed by 157 dental technicians. The sample consisted 80 male and 77 women. The average age was 38. Technicians were working for 9.4 hours a day. About the self equipment most of the participants (94.3%) wear respiratory protective equipment during laboratory work but 5.1% of them do not feel that the use of masks is necessary in laboratory. 13.37% of the participants don’t know the symptoms of silicosis and other 39.47% of them don’t know the right answer. Conclusions: The research has shown that the work safety situation of dental technicians is extremely low and their access to occupational health care is limited. The test results also demonstrated the need for early transfer of basic knowledge about the silicosis disease (its way of preventing, symptom, diagnosis and consequences) among dental technicians. ]
