Hypertension and nephrology - 2011;15(03)

[Great Hungarian physicians have contributed a lot to the development of international medical science. Pál Gömöri was one of them. It is impossible to list the versatility of his scientific interests, but one of his ambitions was the introduction of the investigational methods of renal nuclear medicine to Hungary. The author’s feeling is that his own activity in renal nuclear medicine concerning “diuretic renography” was inspired partly by the information which was learned from Gömöri. The scientific results produced by Gömöri will be preserved in the libraries and on the internet. The spirit of his medical teaching, however, must be passed over by his students and followers, to provide his remembrance to fade as late as possible ]

[Postconditioning in major vascular operations for the prevention of postoperative renal complications]


[Objectives: During vascular surgeries on the abdominal aorta, lower extremities suffer ischaemia-reperfusion (IR) injury which can lead to rhabdomyolysis. A severe complication is the myonephropathic metabolic syndrome with acute renal failure. The aim of the study was to investigate whether postconditioning (rapid repetitive cycles of ischaemia and reperfusion on the onset of the organ reperfusion, a novel technique to reduce ischaemia-reperfusion injuries) could prevent renal failure in major vascular surgery. Subjects and methods: Male Wistar-rats underwent 180 minutes of bilateral lower limb ischaemia and four hours of reperfusion. Postconditioning consisted of 6 cycles of 10-second aortic occlusion/10-second declamping. Microcirculation of the kidney was detected with laser Doppler flowmeter. After 4, 24, 72 hours of reperfusion serum, urine, and histological samples were collected. Acid-base state was evaluated immediately after reperfusion. Results: After four hours of reperfusion there were no significant histological alterations in the muscle in contrast to the 24 hour rhabdomyolysis with inflammation. CK, LDH, AST levels increased in the acute phase but improved in the 24th and 72nd postoperative hours. Kidney histology and laboratory tests showed definite signs of acute tubular injury in control animals. In the early stage serum creatinine; seBUN/creatinin; FENa showed significantly (p<0.05) lower kidney injury in the postconditioned group. Postconditioning improved the kidney cortex microcirculation. Conclusion: Postconditioning can reduce the prevalence and consequences of renal failure after experimental major vascular surgery in rats.]

[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.]

[Association between cyclothymic affective temperament and hypertension]


[Affective temperaments (cyclothymic, hypertymic, depressive, anxious, irritable) are stable parts of personality and after adolescent only their minor changes are detectable. Their connections with psychopathology is well-described; depressive temperament plays role in major depression, cyclothymic temperament in bipolar II disorder, while hyperthymic temperament in bipolar I disorder. Moreover, scientific data of the last decade suggest, that affective temperaments are also associated with somatic diseases. Cyclothymic temperament is supposed to have the closest connection with hypertension. The prevalence of hypertension is higher parallel with the presence of dominant cyclothymic affective temperament and in this condition the frequency of cardiovascular complications in hypertensive patients was also described to be higher. In chronic hypertensive patients cyclothymic temperament score is positively associated with systolic blood pressure and in women with the earlier development of hypertension. The background of these associations is probably based on the more prevalent presence of common risk factors (smoking, obesity, alcoholism) with more pronounced cyclothymic temperament. The scientific importance of the research of the associations of personality traits including affective temperaments with somatic disorders can help in the identification of higher risk patient subgroups.]

[Hungarian Hypertension Study - EMMA]

NAGY Viktor, HORVÁTH Attila, MOLNÁR Katalin, BLASKÓ György, DE Châtel Rudolf

[INTRODUCTION - Ischaemic heart disease and stroke show rapidly increasing incidence and lead mortality statistics in developed countries. Hypertension is the main risk factor for both diseases. With the support of Hungarian Society of Hypertension we performed a public opinion survey on hypertension and on the medicines of its treatment among Hungarian adults between October and December 2001. SUBJECTS AND METHODS - The Omnibus investigation using standardised questionnaires was carried out by monthly home interviews of 5000 participants. RESULTS - One aim of the study was to determine the prevalence of hypertension and the usage of drugs in the population over 35 years. Persistent high blood pressure had been diagnosed in 39% of these population (n=1360). When choosing drugs the lack of side effects is the most important characteristic beside efficacy in this age group. As the study results show, physicians consider regular blood pressure control and screening programs as most important factors for patients with hypertension. CONCLUSION - The results of EMMA study revealed habits and attitudes of regular drug intake. Results also outline the characteristics of the desirable drug that are best accepted by patients - drugs, which patients are faithful to.]

[The prevalence of type 2 diabetes mellitus in the Hungarian population with hypertension]

KÉKES Ede, PÁL László, SCHANBERG Zsolt, KISS István

[Authors had found diabetes mellitus type 2 in 30% of 38 886 hypertensive patients (stadium I-III). Diabetes was more frequent in case of women under 30 years. Subsequently all age groups (from 40 to 80 years) incidence was more frequently (p<0.01-0.001) in men, above 80 years again a higher ratio was in women. Presence of diabetes was correlated to rate of BMI value and systolic, diastolic pressure as well. In women - above 140 mmHg systolic pressure - the elevation was exponential. We have found a significant correlation between fasting glucose and waist. Reaching the target blood pressure is not a simply task in hypertensive patients with diabetes. The 140/90 mmHg was reached in 34.2%, 90 mmHg diastolic blood pressure in 62.3%, but the required 80 mmHg only in 16.4% of cases. Achieve the target value was quite different in the different region of our country. The major cardiovascular complications (stroke, renal disease, myocardial infarction, peripheral artery disease) have suffered a higher rate in the hypertensives with diabetes compered to hypertensives without diabetes.]

[Perindopril plus Indapamid CombinAtion blood preSSure reductiOn study (PICASSO)]

[INTRODUCTION - International and Hungarian (JNC-7, ESH/ESC2007 és 2009, MHT 2009) Guidelines suggest a target blood pressure <140/90 mmHg for hypertensive patients, and <130/80 mmHg for those with high/very high cardiovascular risk (e.g. patients with diabetes mellitus, chronic renal disease). It was proved that for achieving the most efficient antihypertensive effect and reducing side effects, thd use of drug combinations is needed in most patients. In Hungary, ACE-inhibitor plus diuretic combination is one of the most frequently used one in Hungary. The vérnyomáscsökaim of the PICASSO study was to evaluate the efficacy and metabolic effects of the fixed combination of high-dose perindopril plus indapamide (Coverex-AS Komb Forte®) in clinical practice of hypertonologists, cardiologists and general practicioners. PATIENTS AND METHODS - Patients with uncontrolled, grade 1 or 2 primary hypertension, age, >18 years were involved in the open, 3-month, multicentre, prospective, observational, non-interventional clinical study if the treating physician indicated a combination treatment with higher dose antihypertensive drugs. Blood pressure (also with ABPM), heart rate, metabolic parameters (plasma lipids, blood sugar, Na, K, creatinine, uric acid, GGT) were measured by routine methods, medical history and quality of life parameters were registered on a validated questionnaire. Changes in the above parameters were also separately evaluated in patients with different risk factors or with concomitant diseases. RESULTS - Data of 9683 patients were evaluated (54% women, 46% men, average age 61.8 years). By the end of the therapy used in the study, blood pressure average decreased from 159/93 to 131/80, by ABPM from 145/83 to 126/74 mmHg (24hr averages, systolic/diastolic blood pressure, respectively), the heart rate from 79 to 73 beats/min (p<0,001). Target blood pressure was achieved in 75,4% of patients with no major concomitant disease, but only in 14% of those with a concomitant disease characterised by lower target blood pressure. The diurnal index by ABPM did not change substantially. Clinically significant decreases were found in the plasma levels of total cholesterol, LDL-cholesterol, triglycerides, fasting glucose and uric acid levels, but there were no major changes in serum levels of HDLcholesterol, Na, K, and GGT. Quality of life parameters significantly improved by the end of the study. CONCLUSIONS - Combinations of perindopril and indapamide can be successfully and safely used in everyday practice.]

[Too early publication? (priority of the Hungarian authors was saved by a South- American radiologist)]

RADÓ János

[It is supposed that the invention of diuretic (furosemide) renography was a premature discovery. This is suggested by the fact that it was rediscovered by more than one people. Author supported this contention by a statistical analysis of „citation intervals” performed on the basis of Garfield’s suggestions. The length of the time from the description of the procedure to the appearance of citations („citation interval”) proved to be an average of 21.3±9.6 (SD) years, significantly longer than in the case of the author’s five important other recognitions combined, where the average citation interval was 8.7±7.4 (SD) years (p<0.01). Camargo a South-American radiologist who first confirmed the original study, was later just in time the editor of a North American journal to save the priority of the original inventor Hungarian authors. In medical science the investigators take the risks in the interest of the patients including „publishing too early”.]
