[The significance of statin pleiotropy]


NOVEMBER 20, 2009

Lege Artis Medicinae - 2009;19(11)

[Application of statins in the primary and secondary prevention of atherosclerosis is of great importance. Attenuation of cardiovascular risk by statin therapy is primarily related to a decrease in serum cholesterol levels. Scientific data published in the past few years highlight the importance of the beneficial effects of statins that are not related to cholesterol-lowering. These effects are known as pleiotropic effects. This review aims to present the current view of statins’ pleiotropic effects.]

[Cirrhosis and its complications: diagnostic and treatment options]

PÁR Alajos

[During the past two decades, the management of complications of cirrhosis has dramatically changed, which substantially improved the patients’ survival. The present paper provides an overview of the diagnosis, treatment and prevention of cirrhosis and its complications including portal hypertension, variceal bleeding, ascites, hepatorenal and hepatopulmonary syndromes, encephalopathy and bacterial infection. Besides noninvasive diagnostic methods, pharmacological and endoscopic treatment modalities are discussed, with emphasis of the importance of nonselective beta-blockers, vasoactive therapy, antibiotic and albumin medication. Prevention and early diagnosis of cirrhosis as well as new pharmacological agents under development presumbaly result in further development in the management of patients with advanced, chronic liver disease.]

[INTRODUCTION - Until recently, only the proximal small bowel was accessible for diagnostic or therapeutic endoscopy. A new method, doubleballoon enteroscopy (DBE), provides high-resolution imaging and enables both diagnostic and therapeutic interventions in all segments of the gastrointestinal tract. Our aim was to report our experiences with the Fujinon EN-450 T5 therapeutic double-balloon endoscope and compare our findings with the results of earlier capsule endoscopy where this was available. METHODS - Between August 2005 and July 2009, 150 DBE procedures were conducted in 139 consecutive patients (M/F: 67/72, age: 51.1±18.6 years) who presented at our tertiary referral hospital. The examination was performed via the oral route in 112 patients, via the anal route in 16 patients, and via both routes in 11 patients. DBE was indicated due to obscure gastrointestinal bleeding in most cases (83), due to diagnosis or complication of IBD in 29 cases and due to polyposis syndrome or suspected neoplasia in 25 patients. In one patient we performed endoscopic retrograde cholangiopancreatography (ERCP). All procedures were performed using i.v. anaesthesia at our outpatient clinic. After the procedure, the patients were monitored in a recovery room for at least four hours. The results of previous capsule endoscopy were available in 27 patients. RESULTS - Small-bowel abnormalities ? mostly angiodysplasias, minor erosions or ulcers ? were detected in 50 (60.2%) of the patients with obscure gastrointestinal bleeding. Malignancy was found in 7,2% (6/83) of the patients who were examined because of bleeding (three gastrointestinal stoma tumour, one non-Hodgkin lymphoma, one previously undetected melanoma metastasis and one pancreatic adenomacarcinoma that involved the duodenum) Intervention was performed in 24 patients. IBD was diagnosed in five (38.5%) of the 13 patients in whom the disease was suspected. In patients with known Crohn-disease, DBE was indicated on the basis of the extent, behaviour and activity of the disease. Polypectomy was performed in eight patients with Peutz-Jeghers syndrome or familial adenomatous polyposis syndrome, whereas small-bowel adenocarcinoma was diagnosed in four patients. The concordance between the findings of capsule endoscopy and DBE was 51.8% (14/27), and in one patient DBE revealed malignancy that has not been detected by endoscopy. The average insertion length during the procedure was approximately 213 cm (range 50-480 cm, SD 111). CONCLUSIONS - On the basis of our results, DBE is a safe and useful method for assessing and treating small bowel disease, even if capsule endoscopy is contraindicated due to suspected strictures.]

[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.]

[The place of sulphonylurea compounds in the blood glucose lowering therapy of type 2 diabetes]


[The mechanism of blood glucose lowering action of sulphonylureas, their advantages and potencial risks are overviewd in the article. The author delineates the present place of the sulphonylurea group in the antihyperglycemic therapy of type 2 diabetes, listing possibilities of monotherapeutic as well as combined applications. It is emphasized that traditional insulin-secretagogue compounds have their place in the therapy of type 2 diabetes even beside of the new, incretin-type secretagogues.]

[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.]

[The importance of assessing subclinical organ damage in risk prediction of hypertensive patients]

GODINA Gabriella, JÁRAI Zoltán

[As the cardiovascular risk influences the quality and intensity of blood pressure lowering therapy, the goal blood pressure values and the frequency of medical control of hypertensive patients, as well as global risk assessment has an important role in the management of hypertension. In the last couple of years many data have been accumulated showing the poor prognostic value of traditional cardiovascular risk factors. This is the reason why recent Hungarian and international guidelines on the management of hypertension advise the screening for subclinical organ damage. Our goal was to summarize the importance of subclinical organ damage by discussing recently published literature on this topic. An overview has been made on the markers of vascular subclinical damage, like carotid atherosclerosis proved with carotid ultrasonography, peripheral arterial disease assessed with ankle-brachial pressure index measurements and vascular rigidity defined with pulse wave velocity measurements. The prognostic values of myocardial hypertrophy assessed with ECG and/or echocardiography and renal damage proved with decreased estimated glomerular filtration rate and proteinuria are also discussed. Summing up what has been said so far, the assessment of subclinical organ damage has a role in cardiovascular risk prediction, however more randomized and prospective studies have to be performed to define the most suitable (i.e. the most reliable and the most cost-effective) markers for this purpose.]

[Gout, hyperuricaemia and cardiovascular risk - Effects of allopurinol]


[Hyperuricemia has an increasing clinical relevance due to its pathomechanism and its presence and adverse effects on cardiovascular, metabolic and renal diseases today. Its presence is a world phenomenon and in our country, we have seen increasing incidence rates during the screening surveys in recent years. Convincing evidence suggests that the high uric acid values in cardiovascular and renal diseases is an independent risk factor for CV mortality and their clinical manifestations. Experimental and clinical evidences indicates that in addition to gout, all high uric acid levels should be considered to initiate the XO inhibitor allopurinol treatment. Recently, in some diseases, in the treatment of the underlying disease (especially elderly hypertension, ischemic heart disease, chronic heart failure, chronic kidney failure) is also considered as an adjunct therapy.]
