[Enteric-coated mycophenolate sodium (EC-MPS; Myfortic®, Novartis Pharma AG, Basel, Switzerland) is an enteric-coated formulation delivering MPA. Enteric-coated MPS has been developed with the aim of improving the upper GI tolerability of MPA while providing a therapeutical equivalence. The primary objective of the study was to measure the quality of life of kidney transplant patients, with special attention to gastrointestinal symptoms during mycophenolate sodium therapy. The secondary objective was to measure the mean daily mycophenolate sodium dose during routine therapy. These two parameters can significantly influence long-term graft survival of the patients. The study was a multicentric, non-interventional, 12 weeks, single arm, cohort, observational study, in which 251 adult, kidney transplant patients were enrolled in 4 study centers. As part of the study, the patient completed a questionnaire to assess the gastrointestinal status: the Gastrointestinal Symp­tom Rating Scale (GSRS). The patient’s average age was 51.03 years by the time of the inclusion. 61% of the patients were male and 39% female. Kidney transplant was performed averagely 6.3 years (SD: 4.3 years) prior to the screening visit. At the first visit the average intensity of gastrointestinal side effects was 0.87, at the final visit was 0.28. The change of the average number of gastrointestinal side effects between the first and last visit was examined by Wilcoxon test, and it was significant (p<0.0001). Patients had to complete the GSRS questionnaire aiming at five gastrointestinal symptom groups. In all five symp­tom-groups significant (p<0.0001) improvement was observed between the visits. Our results support that, in renal transplant patients with gastrointestinal undesirable effects due to MMF, using enteric-coated mycophenolate sodium may increase the maximum tolerated dose of MPA and reduce GI disorders.]

[Efficacy of maximal dose rosuvastatin therapy in significant carotis stenosis]

KONCSOS Péter

[The main role of atherogenic dyslipidemia is known for decades. Several studies have proven the beneficial effect of statin therapy on cardiovascular morbidity and mortality. The following case report demonstrates the efficacy of high dose statin therapy regarding lipid goals and clinical signs. The presented 65 year-old female patient had a history of dyslipidemia and hypertension for over 15 years and positive cardiovascular family history. Carotid ultrasound examination showed 15-20% bilateral stenosis in 2008 whereas four years later, control ultrasound showed significant progression with 65% left-sided asymptomatic stenosis. At this time, LDL-cholesterol level was above the target; we managed to reach the recommended level with high-dose statin treatment in combination therapy with ezetimibe. Besides the lipid levels, regression of the carotid stenosis could be observed without statin-associated side effects.]

[New opportunities for the estimation of health loss in Hungary]

VITRAI József, VARSÁNYI Péter, BAKACS Márta

[BACKGROUND - The Global Burden of Disease Study has been publishing its reports since the early 1990’s. The last one from 2010 covers 291 diseases, and 67 risk factors for 187 countries. AIMS - Presenting examples of the Hungarian health burden status the authors advocate the use this unique data source. METHODS - The authors downloaded the 1990 and 2010 data for Hungary from the Global Burden of Disease Study website. To quantify the economic burden they calculated the change in GDP related to the absence from work as a consequence of risks and diseases. RESULTS - In the publication the authors presented some of the versatile utilization methods of the GBD data and the data visualization tools available on GDB’s website. In 2010 the DALY for Hungary was 3,714,900 years which is the 84% of the country’s DALY in 1990. The most Years Lived by Disability was caused by musculoskeletal disorders (YLD: 28.4%), while cardiovascular and circulatory diseases caused the most Years of Life Lost (YLL: 40.3%). In 2010 the dietary risk was the leading risk factors in Hungary accountable for 840 thousand of life years lost which economic cost was over 950 milliard Hungarian forints. CONCLUSIONS - The use of the result provided by the Global Burden of Disease Study can significantly contribute for planning and evaluating interventions to promote healthy lifestyle, to advance supporting living conditions, and to distribute health care capacity efficiently.]

[Measurement of ambulatory arterial stiffness index in kidney transplant children]

DÉGI Arianna Amália, KERTI Andrea, KIS Éva, CSEPREKÁL Orsolya, REUSZ György

[Background: Cardiovascular (CV) diseases are the leading cause of death among renal transplant patients (TX). Ambulatory arterial stiffness index (AASI) has been suggested to individually predict the cardiovascular morbidity and mortality. Our aim was to evaluate the relationship between traditional and nontraditional risk factors and AASI in renal transplant children. Patients and methods: In our cross-sectional study, 35 TX patients (15.6±4.3 years of age) were investigated with 24-h ambulatory blood pressure monitoring and AASI was defined. Anthropometric data, metabolic parameters and body composition values were also assessed. Results: By univariate regression analysis, BMI, volume excess, systolic blood pressure SD score, mean pulse pressure, diastolic diurnal index, nocturnal diastolic blood pressure fall, and the presence of hypertension showed positive correlation with AASI (respectively r=0.53, 0.39, 0.34, 0.33, 0.41, –0.42; p<0.05). Hypertensive patients had higher AASI values (0.47±0.13 vs. 0.36±0.18; p=0.04), which may be due to the longer duration of dialysis and longer time since transplantation (p<0.05). BMI SDS and nocturnal diastolic blood pressure fall remained to be the main predictors of AASI in the whole (R2=0.44, SE=0.14, β=0.34 and –0.30, p=0.03) and in the hypertensive group (R2=0.48, SE=0.10, β=0.47 and –0.41, p=0.01 and 0.02). Conclusion: Early transplantation then the early treatment of obesity and hypertension may be essential in the prevention of target organ damage and CV mortality in children after kidney TX.]

SZALAY László

[A nation can only survive and keep its identity through its traditions. This is why the initiative to launch this series coming from professor János Radó is worthy of attention. Gyula Petrányi is an outstanding personality in 20th century internal medicine, to be more precise in nephrology and immunology, his activity being wide-ranging. The first part of the current summmary of his work deals with a tribute to his personality, and his role in immunomodularity treatment in glomerulonephritis. The second part shall cover his role in spreading renal biopsy, screening and caring kidney patients, dialysis, in developing kidney patients’ care, furthermore in clinicopharmacology and renal transplantation.]

[Covid-19 and the kidney]

PATÓ Éva, DEÁK György

[Covid-19 pandemy has emerged from Wuhan, China in December 2019. The infection affects not only the lung but other organs such as the kidney, as well. The relation between Covid-19 infection and the kidney is bidirectional. On one hand, Covid-19 infection may cause kidney damage in 50-75% of the cases resulting in proteinuria, haematuria and acute kidney injury (AKI). The etiology of AKI is multifactorial. Main pathogenic mechanisms are direct proximal tubular cell damage, sepsis-related haemodinamic derangement, citokine storm and hypercoagulability. The virus enters proximal tubular cells and podocytes via the ACE2 receptor followed by multiplication in the lysomes and consequential cell lesion. Histopathology shows acute tubular necrosis and acute tubulointerstitial nephritis. AKI is a strong predictor of mortality in critically ill patients. On the other hand, the risk of Covid-19 infection and mortality is substantially increased in patients with chronic kidney disease – especially in those with a kidney transplant or on dialysis – due to their immunocompromised status. Among haemodialysis patients, infection may spread very easily due to the possibility of getting contacted in the ambulance car or at the dialysis unit. The mortality rate of patients on renal replacement therapy with Covid-19 infection is 20-35%. In order to avoid mass infection it is obligatory to employ preventive measures and implement restricions along with (cohors) isolation of infected patients. In Hungary, every dialysis or kidney transplant patient with Covid-19 infection should be admitted to dedicated Covid-19 wards.]

[Substitution of drugs with narrow therapeutic window in transplant immunology]

LANGER Róbert, TÖRÖK Szilárd

[Because of the economic crisis affecting the health care system, the Hungarian government have envisaged a number of measures. In Hungary, the system of reference support or fixing is an excellent cost-saving tool in the financing of drugs that have a similar mechanism of effect or contain the same molecule. However, in case of certain patient groups and of “critical drugs”, it is to be feared that an inadequate agent might actually bring loss rather than benefit. In this paper, we would like to draw attention to the fact that switching the original microemulsion cyclosporin to generic, no-microemulsion preparations might pose a direct risk for the safety of the transplanted organ and the transplanted patient.]

[Assessment of health related quality of life among epileptic patients in the context of coping strategies and subjective disease perception]

KOVÁTS Daniella, CSÁSZÁR-NAGY Noémi, JUHOS Vera, SALLAY Viola, BÉKÉS Judit, FABÓ Dániel, KELEMEN Anna, KURIMAY Tamás

[Purpose – Psychosocial condition and life quality of epileptic patients are greatly determined by the existence of the disease-related comorbid disorders, like depression, anxiety, and the subjective disease perception, as well as the neuropsychological consequences of the seizures. (Whitehead et al. 2015; Goldstein et al. 2005). It has been examined in patients living with epilepsy how subjective disease perception and coping strategies influence life quality, comorbid depression and the condition of anxiety. Methods – Study patients were asked to fill in a self-completion questionnaire, which examined their psychosocial condition (HADS, Beck Depression Scale), life quality (Qolie-31), coping strategies (FKV-LIS), and subjective disease perception (IPQ-R), as well as sociodemographic and disease variables. The subjects of the study: the data of epileptic patients between the age of 18 to 70 was recorded. Patients were selected from the adult outpatients of a national centre, a regional hospital and two private health care centres located in Budapest. Results – Based on the multiple regression analysis. Beck’s depression (b coefficient=-0.351, t=-4.703, p<0.001**). Depressive coping strategy (FKV Dep) (b coefficient = -0.235, t=-3.123, p=0.002**). Subjective health perception (b coefficient =0.232. t=3.643, p<0.001**). Sex (women; b coefficient =-0.162, t=-3.008, p=0.003**). IPQ consequences (b coefficient =-0.161, t=-2.572, p=0.012*). Active coping strategy (FKV Act; b coefficient =0.146, t=2.572, p=0.012*). Type of seizure (b coefficient =-0.138, t=-2.527, p=0.013*), and Sleep quality (b coefficient =-0.125, t=-1.995, p=0.049) explain some 75.6% of the variance of life quality’s total score (model3: F=33.333, p<0.001**. adjusted R2=0.733). Conclusions – Among the factors of the subjective disease perception (IPQ-R), the physical, mental and social consequences play the most important role. Similarly, the impact of negative emotional representation, as well as the erratic nature of the seizures are decisive. Emotional representation, cyclicity and disease coherence have an important role in coping with disease-related negative emotions. ]
