[Background: Treatment decisions made by patients with chronic kidney disease are crucial in the renal transplantation process. These decisions are influenced, amongst other factors, by attitudes towards different treatment options, which are modulated by knowledge and perceptions about the disease and its treatment and many other subjective factors. Here we study the attitude of dialysis patients to renal transplantation and the association of sociodemographic characteristics, patient perceptions, experiences with this attitude. Methods: In a cross-sectional study, all patients from eight dialysis units in Budapest, Hungary, who were on hemodialysis for at least three months were approached to complete a self-administered questionnaire. Data collected from 459 patients younger than 70 years were analyzed in this manuscript. Results: Mean age of the study population was 53±12 years, 54% was male, the prevalence of diabetes was 22%. Patients with positive attitude to renal transplantation were younger (51±11 vs. 58±11 years), better educated, more likely to be employed (11% vs. 4%) and had prior transplantation (15% vs. 7%) (p<0.05 for all). In a multivariate model negative patient perceptions about transplantation, negative expectations about health outcomes after transplantation, presence of fears about the transplant surgery were associated, in addition to increasing age, with unwillingness to consider transplantation. Conclusions: Negative attitudes to renal transplantation are associated with potentially modifiable factors. It would be necessary to develop standardized, comprehensible patient information systems and personalized decision support in order to facilitate modality selection and to enable patients to make fully informed treatment decisions.]

[Enjoyable and invisible risk: salt The role of the Hungarian Hypertension Society in the National Salt Intake Lowering Program: STOP-SÓ]

KISS István

[Cardiovascular disease accounts for more than 50% of Hungarian mortality and hypertension accounts for almost 50% of coronary heart disease and for more than 60% of stroke. High salt intake increases blood pressure and major and sustained consumption may cause high blood pressure. In Hungary more than 2.5 million people have hypertension and among them only 44% have their blood pressure under 140/90 mm Hg. Achieving target blood pressure is difficult as salt intake of the Hungarian population is higher than that recommended in every age group. Blood pressure control consists of proper combination of medical treatment and of nonmedical procedures. Among non-medical procedures weight loss, increase of physical activity, Mediterranean diet and decrease of salt intake are of value in blood pressure lowering. A daily salt intake of less than 6 grams is recommended in the Hungarian guideline and in the European one the recommendation is more rigorous. However in Hungary average salt intake is 18 grams among men and 14 grams among women. Responsibility of the individual person is inevitable in preserving health and preventing disease. A perfect example for this is the change of salt intake habits as it is demonstrated that decreasing salt intake results in the decrease of blood pressure. A daily decrease of 5 grams in salt intake results in 23% less stroke and 17% less cardiovascular disease. The Hungarian Society of Hypertension has joined among the first to the Hungarian Salt Intake Decreasing Programme and thus its activity is aimed at strengthening the public health subset of the Hungarian Cardiovascular Programme.]

[Hypertension and sexuality]

BARNA István

[Atherosclerosis is a phenomenon of natural aging and as part of it erectile dysfunction (ED) occurs. ED is further aggraveted by smoking, diabetes, atherogen dyslipidemia, obesity, systolic hypertension and vascular disesases (carotid, coronary and peripheral). The average incidence of ED is 19.2% but depending on age (between 30 and 80 years) the relative frequency is fairly different (from 2.3% to 53.5%). Appearence of ED might be the first warning sign of cardiovascular disease. The basis of the treatment of hypertensive males suffering from ED might be the cessation of smoking and quitting alcohol consumption. Optimalization of body weight includes low dietary fat and carbohydrate consumption. Concerning the antihypertensive treatment of males suffering from ED centrally acting agents, diuretics (except indapamide) and beta blockers (except carvedilol and nebivolol) should be omitted. Because of the neutral effect of calcium channel blockers and ACE inhibitors they can be safely administered. There is increasing evidence about ARBs that they have beneficial effect on erectile function and libido, too. If, testosterone production decreases hormone substitution - controlled by an urologist - can be recommended. Oral phosphodiesterase inhibitors (PDE5) can be safely administered even in hypertension. The incidence of sexual dysfunction (SD) among women between ages 40 and 80 is 47%. The most frequent cause in the background of decreased sexual desire among women are psychological, emotional and hormonal reasons or side effect of medication. Several studies proved the association of hypertension, high plasma cholesterol levels, smoking, vascular diseases and sexual dysfunction among women. Disturbance of local blood supply (clitoral, vaginal) is an early prognostic sign, too, like in males. Estrogen hormon replacement might alleviate these symptoms. In recent years sildenafil proved to be effective in several studies and ARBs improve libido, as well.]

[Symptomes and genetics of nephronophthisis]

TORY Kálmán, VÁRKONYI Ildikó, BERNÁTH Mária, RÉMI Salomon, SOPHIE Saunier, MARIE-CLAIRE Gubler, CORINNE Antignac, TULASSAY Tivadar, REUSZ György

[Nephronophthisis is an autosomal recessive, chronic tubulointerstitial nephropathy, responsible for 6-10% of childhood chronic renal failure cases. Its first symptoms, polyuria-polydipsia, anaemia and failure to thrive precede the development of end-stage renal disease by years. Increased echogenicity with loss of corticomedullary differentiation are the key findings on ultrasound, the lack of cysts does not rule out the diagnosis. Histologically, it is characterized by interstitial fibrosis and irregularities of the tubular basal membrane. Genetically, it is highly heterogeneous. Ten nephronophthisis genes have already been identified in 60% of the patients. The encoded proteins - similarly to other proteins mutated in cystic kidney diseases - are localized to primary cilium-basal body-centrosomal complex.]

[The significance of depressive disorders in patients with chronic kidney diseases]

ZALAI Dóra Márta, SZEIFERT Lilla, NOVÁK Márta

[In this article a practice-oriented narrative review of the depressive disorders in chronic kidney disease is provided. Depressive disorders affect approximately one fourth of the chronic kidney disease population. These mental disorders interfere with physical, cognitive and social functioning and are associated with poor prognosis of patients with chronic kidney disease. Bio-psycho-social factors, including immuno-inflammatory processes, disturbance in glucose- insulin homeostasis, sleep disorders, chronic pain, sexual difficulties, changes in social roles, losses in multiple areas of life and low social support increase the risk for the development of depression. Routine, regular screening of depression in the chronic kidney disease population seems to be warranted. Only limited published evidence is available on the therapeutic possibilities of depression in chronic kidney disease. Preliminary evidence indicates that short, structured psychotherapy may be effective for acute treatment and prevention of psychological distress. Some antidepressants can be applied without the need for dose adjustments. On the other hand, some of the psychotropic medications require dose reduction or should be avoided.]

[Dietary treatment of dialysis patients]


[Adequate nutritional indices and intake are the corner stone of long term success of renal replecement therapies (hemo- and peritoneal dialysis, transplantation) characterized by favourable survial rates and a good quality of life. There has been no major change in basic principles of nutritional prescription (protein, energy, fluid intake, restriction of sodium, potassium and phosphorous), increasing emphasis has been placed on the reduction of calcium load and ”native” vitamin-D therapy in these patients. Less avareness has been put however in the past ten years (according to recent metaanalyses) on the role and replacement of the full scale of vitamins, in spite of their occasionally altered metabolism and replacement-requirements in ESRD patients. Usually there is a need for their replacement, but some of them are represented in abundant, sometimes toxic amounts in commercially available multivitamin preparates. With in the scope of general aspects of nutrition in ESRD patients, the article gives a detalied overview of their multivitamin recommendations and alternatives of a specified substition.]

[Prominents in Hungarian nephrology Professor Gyula Petrányi (1912-2000). Part II]


[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 summary 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.]

[Hungarian Vasculitis Registry – results of the first five years]

HARIS Ágnes, TISLÉR András, ONDRIK Zoltán, FILE Ibolya, MÁTYUS János, ZSARGÓ Eszter, DEÁK György, AMBRUS Csaba

[Launching the Hungarian Vasculitis Registry aimed to collect information about prevalence and outcome of our patients with ANCA-associated vasculitis, and treatment protocols of the disease. The on-line data collection has been developing dynamically since its initiation five years ago, presently 278 patients’ files are available. Patients’ mean age is 58.2±14.5 years, 62% are women; their disease is associated with c-ANCA positivity in 51% and p-ANCA in 49%. At diagnosis GFR was 24.6±21.6 ml/min/1,73 m2, that time 29%, during the total follow up 39% of the registered subjects needed dialysis. Renal replacement therapy could be discontinued in 23% of them. In cases with focal histological changes, also with upper respiratory tract and skin involvement dialysis was significantly less frequently necessary, which underlines the importance of early diagnosis. In induction therapy steroid was administered for 94% of the patients, 85% of them got cyclophosphamide, 59% was treated by plasmapheresis, 11% got rituximab. Maintenance treat ment contained steroid in 80%, per os cyclophosphamide in 23%, parenteral cyclophosphamide in 22%, furthermore 40% of the patients got azathioprin, 8 subjects got mycophenolate and 6 got methotrexate. Median follow up was 30 months (IQR 6-78), during which period 20% of the patients died, 5% got kidney transplantation, and 5% were lost to follow up. Median survival was 14.8 years, five years survival was 85%, and ten years survival was 70%. Long term survival in patients with c-ANCA vasculitis seemed better comparing to p-ANCA vasculitis, but when correcting by age this difference disappeared. Predictors of death were age and dialysis dependent renal failure. Relapses developed in 27% of patients, 28% of them presented in the first year, 21% suffered it after five years of care. Collected data by the Hungarian Vasculitis Registry shows our society’s successful professional activity. Our results are comparable to the published data in the literature, yet there are several areas in our care where further improvements are warranted in order to increase our patient’s survival and quality of life.]
