[Examination of the efficacy of clopidogrel-hydrogen-sulphate in patients with cerebrovascular disease]

SZAPÁRY László, FEHÉR Gergely

[INTRODUCTION - On the basis of current guidelines, acetylsalicylic acid plus dipyridamole or clopidogrel monotherapy should be used for the long-term treatment of patients with cerebrovascular disease, whereas acetylsalicylic acid monotherapy is not recommended. The efficiency of recently introduced generic clopidogrels has not been assessed in patients with a history of acute stroke. PATIENTS AND METHODS - 100 patients with a history of acute stroke or transient ischaemic attack were involved in our study. The patients received acetylsalicylic acid monotherapy in the first 48 hours, followed by clopidogrel-hydrogen sulphate (Egitromb®) monotherapy. The efficiency of the therapy was assessed on day 7 and 28 of medical therapy. RESULTS - At the first measurement (day 7) after clopidrogel-hydrogen sulphate treatment, the therapy seemed to be inefficient in 11 patients (11%). A strong, clinically significant correlation was found between blood pressure values, blood glucose and lipid parameters, hsCRP levels and platelet aggregation values. At the second measurement (day 28), an aggressive secondary preventive threapy resulted in the normalisation of the above mentioned parameters, and the efficiency of platelet aggregation inhibtion therapy was also improed, whereas no patients proved to be resistant. No unwanted events or haemorrhagic complications were registered. CONCLUSIONS - On the basis of the result of our study, treatment with clopidogrel- hydrogen sulphate is safe and efficient both clinically and on the basis of optical aggregometry. The significance of an aggressive secondary preventive therapy should be considered as a factor that might influence the efficiency of thrombocyte aggregation inhibitory therapy.]

[Perioperative management of patients with coronary stent in case of interventions other than cardiac surgery - Part I. - Perioperative treatment of patients with coronary stent]

ZIMA Endre, MEZŐFI Miklós, BECKER Dávid, SZABÓ György, MERKELY Béla, PÉNZES István

[Percutaneous coronary intervention (PCI) is meant to optimalise cardiac status, that is, short-term and long-term outcomes. It is known from large Western databases that stent implantation is performed in 77-85% of coronary interventions, which means hundreds of thousands of new patients with stent every year. The great majority of these patients has to take platelet aggregation inhibitors, namely acetylsalicylic acid and thienopyridin, most often clopidrogel. It presents a major therapeutic dilemma when these patients require noncardiac surgery. First, surgery should be performed with the least possible blood loss, which would be optimal if the platelet aggregation inhibitor therapy - that is indispensable for a certain period because of the stent - was suspended. Second, stent thrombosis has to be avoided, which can only be achieved if platelet aggregation inhibitor therapy is continued. The aim of our paper is to summarise the current guidelines and the risk estimation on the basis of our current knowledge in the perioperative management of patients with coronary stent. In the first part, we overview the platelet aggregation inhibitor agents, their mechanisms of effect, stent types and the minimal therapeutic period to be strictly observed, which depends on the type of stent.]

[Amlodipine/atorvastatin fix combination in type 2 diabetes mellitus]

BÓTYIK Balázs

[INTRODUCTION - Type 2 diabetes mellitus is known to represent a major cardiovascular risk. In type 2 diabetes, hypertension and dislipidemy are often also present, increasing the vascular risk. In this case the use of both antihypertensive and lipid lowering therapies is needed. In our CASE REPORT, we discuss the data of a 43 years old diabetic man with BMI: 29.4 kg/m2, waist circumference of 101 cm, who had recently diagnosed hypertension and was given single pill amlodipine/ atorvastatine in addition to his original ACEI therapy. At the initiation of the therapy the mean blood pressure - measured during ABPM was 149/91 ± 14.99 Hgmm, his total cholesterol: 4.18 mmol/l, HDL cholesterol: 0.82 mmol/l, LDL cholesterol: 2.41 mmol/l, and triglicerid: 4.09 mmol/l. Three months later the results were the following: mean blood pressure: 121.66/ 82.79 ± 8.21 Hgmm, total cholesterol: 3.47 mmol/l, HDL cholesterol: 1.08 mmol/l, LDL cholesterol: 1.98 mmol/l, triglicerid: 1.44 mmol/l. There were no side effects. Using the therapy among several other diabetic patients we observed similar efficacy and tolerability, and the adherence of the patients was perfect. DISCUSSION - In type 2 diabetes the use of the fix combination of amlodipin/atorvastatin in addition to previous ACEI therapy is effective, well tolerated, and the long term compliance proves to be good.]

[Antidiabetic therapy of patients with type 2 diabetes - The place of administration of acarbose]

KEMPLER Péter

[Administration of the alpha-glucosidase enzyme inhibitor acarbose leads to a prolonged absorption of carbohydrates, which has a smoothing effect on blood glucose excursions, and results in a more even daily blood glucose profile. The glucose lowering effect is mainly due to the reduction of postprandial blood glucose levels. Non-glycaemic effects of acarbose, including those on blood pressure, lipids and the coagulation system are also clearly beneficial. According to the available data, the preparation also reduces cardiovascular risk. If used as a monotherapy, acarbose does not cause hypoglycaemia. Flatulence and diaorrhea represent the main side effects. From a professional point of view, acarbose should be given if postprandial blood glucose excursions exceed 2.2 mmol/l.]

[EVIDENCE BASED ORAL ANTIDIABETIC THERAPY]

JERMENDY György

[Oral antidiabetic drugs are used in type 2 diabetic patients when diet and physical exercise have failed. The oral antidiabetic drugs available in Hungary can be classified according to their main effect. In this regard, antihyperglycaemic drugs with no hypoglycaemic potential (alfaglucosidase inhibitors, biguanides, thiazolidinedions) and drugs with a potential of insulin secretion (sulfonylureas, prandial glucose regulators) can be distinguished. Acarbose is mainly used in order to decrease the postprandial glucose excursion. Metformin is the drug of choice for obese, insulin resistant diabetic subjects while buformin is not preferable anymore since the availability of metformin. Rosiglitazone, the only thiazolidine-dion derivative in Hungary, can be used in combination therapy in diabetic subjects with clinical characteristics of the metabolic syndrome. The list of sulfonylureas contains five drugs in Hungary which enables differential therapeutical strategies to be performed. The prandial glucose regulators can be used either in monotherapy or in combination with other drugs at the relatively early stage of the disease. At present, the recommendations for treating diabetic patients with oral antidiabetic drugs can be based on clinical evidences.]

[DISEASES OF THE EXOCRINE PANCREAS AND DIABETES MELLITUS]

CZAKÓ László

[Exocrine and endocrine pancreas constitutes close anatomical and functional links accordingly, any disease affecting one of these sectors will inevitably affect the other. Acute and chronic pancreatitis, pancreatic surgery, cystic fibrosis and pancreatic cancer are those pancreatic conditions that might cause diabetes mellitus. The development of diabetes greatly influences the prognosis and quality of life of patients with exocrine pancreatic diseases. The lack of glucagon and the impaired absorption of nutrients may cause life-threatening complications, such as hypoglycaemia, and the micro- and macrovascular complications may impair the organ functions. Diabetes mellitus is an independent risk factor of mortality in those with exocrine pancreatic diseases. Pancreatic diabetes is a distinct metabolic and clinical form of diabetes, requires special treatment. Diet and pancreatic enzyme replacement therapy may be sufficient in the early stages. Oral antidiabetic drugs are not recommended. If the diet proves inadequate to reach the glycaemic goals, regular insulin treatment is demanded. There are special impairments of the exocrine function and the pancreatic morphology at diabetic patients that resemble to chronic pancreatitis. Atrophy of the exocrine tissue may caused by the lack of trophic insulin. Hyperglycaemia can activate the stellate cells that lead to pancreatic fibrosis. The microangiopathy and neuropathy, as well as the lack of islet hormone action - responsible for the exocrine pancreas regulation - will cause further damage on the pancreas glandular tissue. In the event of a proven impairment of the pancreatic exocrine function in diabetes mellitus, pancreatic enzyme replacement therapy is recommended. This may improve the nutritional condition and decrease the metabolic instability.]
