[Chronic renal failure is a major health problem, affecting 8 to 16% of the population. Regardless of the etiology the common hallmark of chronic renal failure is inflammation, leading to the activation of renal myofibroblasts. Chronic activation of myofibroblasts lead to abnormal accumulation of extracellular matrix, disruption of the architecture of the kidney and finally to reduced renal function. Although our knowledge is rapidly expanding about the pathomechanism of chronic renal failure, we still have no drug to treat or hinder the progression of the disease. In our present review article, we summarize the role of the cytokines of the IL-10 family in renal scarring.]

[Hungarian Hypertension Registry. Different methods and effects of increasing physician-patient cooperation on target blood pressure]


[The life expectancy, the mortality and the development of complications of hypertensive patients are fundamentally influenced by the treatment, the effectiveness of care and physician-patient cooperation, the achievement of target blood pressure. Based on the database of the Hungarian Hypertonia Registry, we present three examples of the effect of different solutions for physician-patient cooperation on increasing the blood pressure target. During the two years between 2005 and 2007, we used a complex, versatile method of increasing the patient’s adherence in treated hypertensive patients (17,114 males and 21,772 women), with information, education, home-blood pressure diary, and continuous, regular physician- patient communication (sms, green phone line, website). The target blood pressure was significantly increased from 38.8% to 43.9%, and the rate of growth was higher in women. The increase was also significant in the elderly (over 70 years). In the first quarter of 2011, we launched a wide-ranging education and patient support campaign for 28,018 hypertensive patients under the ‘Everywhere Good, Best Home!’ subprogram for promoting of home blood pressure measurement and its use in therapy. 81.3% of the patients had completed the diaries under ther observation period, the full completion of the diaries was 91.3%. At the end of the third month, the target blood pressure of 135/85 mmHg for HBPM increased from baseline 21.2% to 48.8%. Growth was significant (P <0.001). In the year 2015-2016 we started a one-year, multicentric, prospective, observational study, in which 7735 patients aged 18-64 years were included from the database of Hungarian Hypertension Registry. In the non-active group (3313 people), treated hypertensive patients were controlled according to the traditional care program so far, while the active group members (4422) participated in an intensive care program with telemedicine (smart phone application) and other helping opportunities. The control was done at the end of 3, 6, 9, and 12 months after the start. In the active group, blood pressure dier was done by smart phone and every month, in the non-active group, paper logging was done every 3 months. In the active group, the blood pressure dieries were filled with smart phone every month and in nonactive group the paper dieries only every 3 months. Patient adherence was high in both groups (around 70%) and in the active group was greater than in the nonactive group. Target blood pressure (<140/90 mmHg) in the active group increased from 53.8% to 73.4% and in the non-active group from 49.9% to 68.1%. Studies have shown that patient interaction is determined by good communication between the care team and the patient, success of home blood pressure monitoring. The communicative ability of the care team (physician-nurse pharmacist) greatly influences the achievement of the therapeutic target. Modern telecommunications is another useful option.]

[The prevalence of therapy resistant hypertension]


[In our country as well as around the world the most common chronic disease is the hypertension, and it is also an important risk factor causing disability and premature death. Within this, getting to know the true prevalence of therapy- resistant hypertension is important also from a public health perspective, since the prognosis of it is worse than that of those who reaches goal blood pressure range. It usually comes with hypertension mediated organ damages and higher (2- 2.5 folder) cardiovascular risk. It is prevalence in the literature is from 5% to 30%. The knowledge of the true prevalence depends on many factors, like: there are many different definitions of resistant hypertension, what is the main profile of the data collecting study site and what level of the health care system it works, or for example a questionnaire of a multicenter trial cannot be used totally in each country and study site.]

[Serum uric acid level in hypertension. Domestic experience based on the data of the Hungarian Hypertension Registry 2011., 2013. and 2015. Part III. - Relation of uric acid to clinical and laboratory characteristics]


[2013. and 2015, we examined the correlation between the serum uric acid level and blood pressure, target blood pressure, prevalence of ISH and other diseases associated to high blood pressure used trend analysis and linear regression in 22,668 hypertensive men (mean age 60.8 years) and 24,684 hypertensive women (mean age 64.1 years). We have extended the correlation analysis to metabolic factors (BMI, abdominal circumference, lipid profile, blood sugar) and kidney function. Significant correlation was found between SH level and systolic and diastolic blood pressure as well as target blood pressure. There was a significant correlation between SH level and metabolic parameters (abdominal circumference, BMI, total cholesterol, HDL cholesterol, triglyceride, fasting blood sugar) and in hyperuricemia the prevalence of metabolic syndrome was higher. As the level of SH increases, the prevalence of hypertension-related KVB, ISZB and diabetes have increased. The closest correlation between uric acid levels and chronic kidney disease was in women and between the uric acid levels and ischemic heart disease in men. ur analysis supports the international declaration that hyperuricemia is an independent cardiovascular, metabolic and renal risk factor.]

[Hypertension and pregnancy]

JÁRAI Zoltán, VÁRBÍRÓ Szabolcs

[Hypertension complicates approximately 10% of the pregnancies and with this high blood pressure is the most frequent cardiovascular comorbidity during pregnancy. Hypertension during pregnancy accounts for a substantial maternal and perinatal morbidity and mortality risk. In our review we focus on the forms, diagnosis and therapeutic possibilities of gestational hypertension according to the European and domestic guidelines.]

[Treatment of hypertension in patients with chronic renal failure]


[The prevalence of chronic renal failure and hypertension is steadily increasing worldwide. The risk of possible cardiovascular death in patient with advanced renal failure is greater than the risk of progression to end-stage renal failure. Therefore treating and achieving target blood pressure is important in order to slow renal function decline in parallel with cardiovascular risk reduction. However, guidelines do not specify a single blood pressure target to be achieved in patients with renal failure, but suggest evidence based, reno- and cardioprotective therapy. This paper summarizes the clinical practice of treating hypertension (drug and nondrug treatment, therapeutic algorithm, target value, effectiveness of therapy) in patients with chronic renal failure.]

[Nutritional status of hemodialysis patients, and the role of dietician in the complex care of renal patients]

POLNER Kálmán, KOVÁCS Lívia, HARIS Ágnes

[In chronic renal failure severe cardiovascular complications develop, which are the cause of death in 50% of the patients. According to recent results, behind the accelerated atherosclerosis, malnutrition and inflammation, developing in patients with chronic renal failure, play significant role. Malnutrition and inflammation show close relationship to the serum albumin level, which is an independent predictor of mortality. Authors studied the nutritional parameters of 94 chronically hemodialysis patients. Patients had been dialysed for more than three months, for 3×4-4.5 hours weekly. Among them 36% had diabetes. According to BMI (body mass index) 42.5% of the patients was normally nourished (20-24 kg/m2), 11.7% of them had malnutrition, 28.7% was overweight, and 17.1% was mildly or moderately obese. Subjective Global Assessment (SGA), calculated by dietician, revealed, that 47.9% of the patients has normal nutritional condition, all the others had some degree of malnutrition. Serum albumin level showed close correlation with the nutritional status, also with an inflammatory marker, the CRP. Only 63.8% of the patients had higher than 40g/l serum albumin. Those, who had higher than 10 mg/l CRP value, had significantly lower serum albumin (38.7±3.4 g/l), comparing to the albumin of the patients, whose CRP was below 10 mg/l (40.5±3.9 g/l, p=0.04). Comparing anthropometrical data, there was no significant difference between diabetic and non-diabetic patients. Grouping patients by their ages, the malnutrition, defined by SGA scores and by serum albumin level, was significantly worse in patients older than 80 years, than in the younger than 50 years old subjects, which signals increased risk of mortality of the elderly patients. A case presentation demonstrates, that malnutrition can be diagnosed at early stage by appropriate nutritional assessment, and it can be corrected by timely and satisfactory energy- and nutrient-substitution, in severe cases by specially prepared nutritional supplements, and thereby the patient’s severe cardiovascular risk can be ameliorated. The successful treatment of hemodialysis patients requires change in medical practice, and close cooperation between physicians and dieticians.]

[Prognostic significance of invasion in glioblastoma]


[Glioblastoma is the most common malignant CNS tumor, its surgical removal is hindered by the tumors invasive nature, while current anti-tumor therapies show limited effectiveness – mean overall survival is 16-24 months. Some patients show minimal response towards standard oncotherapy, however there are no routinely available prognostic and predictive markers in clinical practice to identify the background of mentioned differences in prognosis. This research aims to identify the prognostic significance of invasion-related extracellular (ECM) components. Patient groups with different prognoses were created (OS: group A <16 months, group B > 16 months), and internationally recognized prognostic markers (IDH1 mutation and MGMT promoter hyper-methylation) were tested in the flash-frozen tumor samples. Furthermore, the mRNA levels of 46 invasion-related ECM molecules were measured. Clinical data of the patients who have been operated on at the University of Debrecen Clinical Center Department of Neurosurgery and treated at the Department of Clinical Oncology showed no significant differences except for survival data (OS and PFS), and reoperation rate. All samples were IDH wild type. MGMT promoter hypermethylation rate showed significant differences (28.6% vs 68.8%). The expressional pattern of the invasion-related ECM molecules, i.e. the invasion spectrum also showed major differences, integrin β2, cadherin-12, FLT4/VEGFR-3 and versican molecules having signficantly different mRNA levels. The accuracy of the inivasion spectrum was tested by statistical classifier, 83.3% of the samples was sorted correctly, PPV was 0.93. The difference found in the reoperation rate when comparing different prognostic groups aligns with literature data. MGMG promoter region methylation data in Hungarian samples has not been published yet, and further confirming current knowledge urges the implementation of MGMT promoter analysis in clinical practice. Studying the invasion spectrum provides extra information on tumors, as a prognostic marker it helps recognizing more aggressive tumors, and calls attention to the necessity of using anti-invasive agents in GBM therapies in the future.]

[The autosomal dominant papillorenal syndrome results from primarily de novo mutations of PAX2. It encodes a transcription factor expressed in the kidney, urinary tract, nervous system, eye and the ear. Its haploinsufficiency causes primarily hypoplastic and hyperreflective kidney, or other forms of CAKUT. The clinical appearance may be dominated by nephrotic-range proteinuria with focal segmental glomerulosclerosis. The renal survival rate is highly variable: most of the recognized cases lead to ESRD during the first four decades of life. PAX2 mutations cause typical optic papillary alterations, most frequently papillary dysplasia. In contrast to the name of the syndrome, one fourth of the affected patients do not develop ocular involvement. Hearing impairment is associated in less than 10% of the patients. The affected members of the five families that we identified with PAX2 loss-of-function mutations, developed end-stage renal disease during the 2-4. decades of life.]

[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.]
