[ABNORMAL ALBUMINURIA IS A CARDIOVASCULAR RISK FACTOR IN DIABETIC PATIENTS - ACHIEVING THERAPEUTIC GOAL IN PRACTICE]

[The stages of abnormal albuminuria are microand macroalbuminuria. The isolated abnormal albuminuria is a special form of proteinuria. For the detection of abnormal albuminuria one can use immunological or liquid chromatographic methods. The latter seems to be more appropriate than the immunological methods for the measurement of albuminuria in normo- and microalbuminuric diabetic patients. In diabetes mellitus, the circulating glycated and oxidized albumin is degraded and eliminated in the kidney. Decrease of the glomerular filtration rate is a valuable measure of renal insufficiency and this loss of kidney function is followed by the decrease of albuminuria as a sign of the glomerular closure. Albuminuria is an important cardiovascular risk factor and the decrease of the abnormal albuminuria is associated with a diminishing cardiovascular risk. Thus, albuminuria is a cardiovascular therapeutic target, as well. Therefore, the major points of the management of diabetic albuminuria are the achievement of euglycaemia, the use of angiotensin converting enzyme inhibitors and/or angiotensin receptor blockers.]

[Oxidative stress plays an important role in the elevation of the cardiovascular risk of patients with chronic kidney insufficiency. The oxidative stress becomes more severe together with the deterioration of the renal function, and the hemodialysis sessions may also induce repetitive oxidative insults. Erythropoesis-stimulating agents (ESAs) may alter the level of oxidative stress via their effects on hematopoiesis, resulting in indirect effects on changes of iron metabolism and the levels of antioxidants. We review the current knowledge about the administration of ESAs as concerns effects on oxidative parameters in hemodialysis patients. We discuss the relationship between the characteristics of the ESA therapy (type, administration frequency and dosage of ESA, length of the therapy, administration withdrawal) and the oxidative stress in view of earlier and recent research.]

[The diagnostic value of a glass of soda water in case of a cardiac space-occupying lesion]

PÁLINKÁS Attila, CZAKÓ László, CSÁSZÁR Ildikó, NAGY Edit, SZABÓ Marianna

[INTRODUCTION - Large hiatal hernias may result in cardiac space-occupying lesions. Our case study discusses the clinical aspects and the possible diagnostic approaches for such large hiatal hernias that cause cardiac compression. CASE REPORT - In an elderly patient with no cardiovascular symptoms, transthoracic echocardiography revealed a left atrial space-occupying mass. The diagnosis regarding the origin of the cardial mass was clarified by a glass of soda water drunk by the patient during echocardiography, as it resulted in a decrease in the inhomogenous echodensity of the mass and the appearance of “contrast bubbles” within it. This phenomenon suggested the presence of a large hiatal hernia compressing the heart, which was confirmed by gastroscopy and upper gastrointestinal barium examination. CONCLUSION - Drinking soda water during transthoracic echocardiography can help to diagnose lesions that look like intracardial tumours.]

[ANGIOTENSIN-CONVERTING ENZYME INHIBITORS AND ANGIOTENSIN-2 RECEPTOR BLOCKERS IN CHRONIC HEART FAILURE]

ZÁMOLYI Károly

[The rennin-angiotensin system plays a major role in cardiovascular diseases. In the past decade, extensive research investigated the possible clinical benefit of the use of angiotensin-converting enzyme inhibitors in various clinical conditions. Their benefits have been clearly demonstrated in many cardiovascular conditions and agreement as to their potential usefulness has been established in chronic heart failure, asymptomatic left ventricular dysfunction, acute myocardial infarction and hypertension, and in the primary prevention in patients with high risk for cardiovascular events. Numerous randomised clinical trials over the past two decades established their efficacy in reducing adverse outcomes (mortality, hospitalitazion, and physical limitation) in patients with heart failure and left ventricular systolic dysfunction. Based on these results, angiotensin-converting enzyme inhibitors are indicated in all patients with left ventricular systolic dysfunction regardless of etiology, in the absence of intolerance or a contraindication. Despite the recent improvements in the treatment of heart failure, mortality remains high, with approximately 50% patients dead at five years. Although angiotensinconverting enzyme inhibitors decrease mortality, they incompletely suppress angiotenzin-2 when used chronically. Since angiotensin receptor blockers block the biologic effects of angiotenzin-2 more completely than angiotensin-converting enzyme inhibitors, they may be beneficial in the treatment of heart failure. In comparison trials, angiotensin receptor blockers were found to have no benefit over angiotensin-converting enzyme inhibitor therapy. Thus, angiotensin-converting enzyme inhibitors should remain first-line treatment for heart failure. However, in case of intolerance, angiotensin receptor blocker therapy is a reasonable substitute and provides excellent tolerability.]

[UNALTERED MRNA EXPRESSION OF CALCITONIN-LIKE RECEPTOR AND RECEPTOR ACTIVITY MODIFYING PROTEINS IN HUMAN ARTERIES IN STROKE AND MYOCARDIAL INFARCTION]

[Calcitonin-like receptor (CL-R) is a functional CGRP1- receptor when complexed with RAMP1 or an adrenomedullin-receptor or when complexed with RAMP2 or RAMP3. This study was carried out 1. to set up a method to examine the relative quantity of mRNA of CL-R, RAMP1, RAMP2 and RAMP3 in human coronary (CA), pulmonary (PA) and middle cerebral arteries (MCA), and 2. to examine the level of mRNA expression in cerebro- and cardiovascular diseases. The method was validated with respect to the use of postmortem tissue and we compared β-actin and GAPDH as housekeeping genes. There was no time-dependent change in total RNA and level of mRNA for β-actin or GAPDH could be detected in vessels removed from 1 and 5 days post mortem. The expression of β-actin appears lower in coronary artery than in pulmonary artery and middle cerebral artery with no significant difference for GAPDH; both worked well. There were some differences in mRNA expression for CL-R (higher) and RAMP3 (lower) in middle cerebral artery compared to coronary artery and pulmonary artery. There was no significant difference in mRNA for RAMP1 and RAMP2 in the three types of arteries. We did not observe any difference in mRNA for CL-R and RAMPs in arteries from patients with hemorrhagic stroke, arteriosclerosis and acute myocardial infarction when compared to patients without these diagnoses. Thus the mRNA expression seems to be unaltered in these disorders.]
