[Due to the progressive nature of the type 2 diabetes mellitus and treatment requires prolonged lifestyle and/or pharmacologic management, the long term efficacy, durability and safety of newer antihyperglycemic agents are important considerations. Metformin is the most common prescribed oral antihyperglycemic agent (OHA) for initial therapy. Often, initial single oral agent is not sufficient to maintain good glucose control, combination of OHA are usually required to manage patients with type 2 diabetes. Incretinbased therapies (e.g. dipeptidyl peptidase 4 (DPP 4) inhibitors and analogues of glucagon like peptide 1) are newer compounds available for the treatment of type 2 diabetes. Sitagliptin is a once-daily OHA with a novel mechanism of action that targets the incretin axis. Addition of sitagliptin to ongoing metformin therapy was well tolerated and resulted in significant glycemic improvement after 30-104 weeks of treatment in patients with type 2 diabetes.]

[The multidisciplinary pathological examination of colorectal carcinomas - From the biopsy sample to the K-RAS mutation analysis]

BOGNER Barna

[BACKGROUND - The role of pathologist in the reporting of colorectal carcinomas (CRC) has dramatically changed in the past 20 years. This change has been generated by the enormous progress in the surgical, radiological, oncological and pathological techniques and their interactions. AIM - To interpret the role of pathologist in the colorectal multidisciplinary team. METHODS - The most important histopathological prognostic and predictive factors, the surgical planes, the involvement of circumferencial margin, the regression grade after neoadjuvant chemoradiotherapy were assessed in 964 patients treated with operable colorectal cancer during 2001-2007 in the County Hospital of Baranya and the four nearby city hospitals. RESULTS - Most of our patients (>75%) were treated with advanced stage tumors. The lymph nodes were harvested through careful slicing, visual inspection and palpation - accordingly the average lymph node count increased from 7.45 to 19.0. After using elastic fibre stain we detected twice as much vascular invasion then before. The results of the surgical quality after TME and APER were somewhat dissapointing. Although the ratio of the specimens resected in the mesoretal fascial plane was comparable to the international results (39.8%), the ratio of resections in the muscularis propria plane was unacceptably high (47.8%) and it was more pronounced (50-100%) between the low volume surgeons of the small city hospitals. The involvement of the circumferencial resection margin was affected by the advanced pT and pN stage, the vascular invasion, the surgical plane, the type and number of resection performed by the surgeons, the regression grade after preoperative chemoradiotherapy and the gender. CONCLUSIONS - In addition to the traditional histopathological features the pathologist has to investigate the quality features of the preopreative assessment, the surgical planes of excision and the grade of regression after neoadjuvant chemoradiation and feed back these results to the members of the CRC multidisciplinary team. The optimal treatment of the CRC can be achived only in this setting.]

[The role of the DPP-4 inhibitor sitagliptin in the therapy of type 2 diabetes, in light of the new guidelines]

HIDVÉGI Tibor

[Type 2 diabetes has become a global public health problem, threatening the economies of all nations, as a consequence of rapid urbanisation, changing eating habits, sedentary lifestyle and obesity. Asian populations tend to develop diabetes at younger ages and lower body mass index compared with Caucasians. The latest guidelines of the American Diabetes Association and the European Association for the Study of Diabetes recommend lifestyle interventions as the first step for patients with newly diagnosed type 2 diabetes. The widely used metformin remains one of the first-line drugs for type 2 diabetes. If monotherapy alone does not achieve or maintain the target HbA1c level, addition of a second oral agent is recommended as a second step. The highly selective dipetidyl peptidase-4 inhibitor sitagliptin and metformin are efficient and well tolerable. The complementary effects of sitagliptin and metformin lead to an efficient, safe and long-term improvement in glycaemic control.]

[The development of insulin treatment from discovery of insulin to analogue preparations]

KÁPLÁR Miklós, PARAGH György

[The discovery of insulin was a milestone in the treatment of diabetes mellitus. Animalderived (porcine and cattle) insulins available at the beginning were later replaced by human insulins. Recently, analogue insulins are the most widespreadly used. Besides the increase in the quantity and improvement in the quality of the insulin products, the growth of the treatment regimes is apparent, as well. That varies from the once-given daily basal insulin treatment added to oral antidiabetic drugs to intensified insulin therapy, administering insulin 4-5 times daily. Considering the benefits proved by previous basic and clinical studies, the authors summarize the most important properties of the commonly used insulin treatment regimes in this review. They also briefly outline the important aspects of the patient-centered personalized therapy and the connection between insulin therapy and carcinogenesis.]

[EFFICACY, SAFETY AND EFFECT ON THE QUALITY OF LIFE OF GABAPENTIN IN ADULT EPILEPSY - RESULTS OF A PROSPECTIVE OPEN-LABEL QUASI NATURALISTIC HUNGARIAN MULTICENTER STUDY (PHASE HUMAN-IV).]

RAJNA Péter, SZÍJÁRTÓ Elvira

[Purpose - To evaluate the efficacy and safety of gabapentin (GBP) in idiopathic or crypto/symptomatic partial epilepsy in adults. Methods - We performed a prospective open label add-on study in pharmacoresistant patients with simple or complex partial or generalized seizures of partial onset (at least four seizures per month). GBP was added to no more than two baseline antiepileptics and the efficacy was rated primarily according to the seizure frequency. The secondary efficacy parameters were the change in the seizure severity scores (measured by the NHS3 scale) and in the quailty of life (measured by the QUOLIE-31 questionnaire). GBP was added up to 1500-1600 mg per day in the titration period than an individual optimalization was allowed in any further visits. The follow-up period was three months. Population - Fourteen Hungarian epilepsy out-patient unit participated in the study. 72 patients were enrolled, GBP was applied in 63 persons (ITT population) and 57 completed the study. Results - A more than 50% decrease in seizure frequency was found in more than 70% of the patients in the third month. Among them just every third patient became seizure-free. Significant improvement appeared also in the severity of seizures and in the total score of the quality of life questionnaire. There was no difference either according to the etiology of the epilepsy or the seizure types. GBP was tolerated excellently. There was no need to decrease of the dosage of GBP and the side effects were mild and of transitory nature. Consequences - GBP appears to be a valuable antiepileptic drug considering its high efficacy and extremely favourable tolerance. While GBP also decreases the severity of the seizures, its complex effects result an improvement in the quality of life of the patients. The positive effects have been durable during the follow-up. Open label naturalistic studies of larger population are needed to clear the special indications of GBP in chronic partial epilepsies.]

[PErindopril-Amlodipine Reducing Blood Pressure Level Trial - The PEARL Study]

NAGY Viktor, LANTOS Éva, HABONY Norbert

[Background and aims - In order to reach target blood pressure values more successfully and to achieve better therapeutic compliance, concomitant use of more antihypertensive agents with different mechanisms of action has gained much attention recently. In the PEARL study we investigated the antihypertensive effect of fixed dose combinations of perindopril and amlodipine (5/5, 5/10, 10/5, 10/10 mg Covercard) by measuring blood pressure values in the doctor’s office and with a 24-hour ambulatory blood pressure monitor (ABPM) in outpatients with primary, grade 1 or 2 hypertension, whose target values could not be reached with prior treatment. We also assessed changes of metabolic parameters and how patients felt themselves throughout the study. Patients and methods - In this open-label, multicentre, non-interventional, observational, 3 month long study we evaluated the data of 10 335 patients (5 483 female, 4 852 male, mean age: 61.0±12.4 years, waist circumference 99.0±13.8 cm). The mean duration of hypertension was 9.5±7.7 years. After signing the informed consent form, patients attended three visits (inclusion, months 1 and 3), and they were asked to fill in the data sheets (visit 1: gender, age, waist circumference, blood pressure and heart rate measured at the doctor’s office, duration of hypertension, risk factors, complications, accompanying diseases, previous antihypertensive treatments, complaints), laboratory blood tests and ABPM were optionally performed; visits 2 and 3: blood pressure and heart rate measured at the doctor’s office, adverse events, patient’s evaluation about the way they felt themselves, treatment, optionally performed laboratory blood tests and ABPM. Patients were asked to take perindopril-amlodipine fixed combination tablets in the mornings; the dose was increased if no normalization of blood pressure was observed. Data were analyzed with a one-sample t-test. The consistency of the different frequency distributions was tested with a Chi-square test. The two-sided level of significance was set at 5%. Results - All the parameters sensitive to treatment efficacy (blood pressure values measured on-site and with ABPM) were significantly improved with perindopril-amlodipine fixed combination treatment. Blood pressure measured at the doctor’s office reduced from 158/93 mmHg to 132/80 mmHg, while 24-hour mean blood pressure reduced from 145/84 mmHg to 128/76 mmHg (p<0.001), the diurnal index sensitive to blood pressure variability did not change and a dipper curve was observed throughout the study. Target blood pressure (<140/90 mmHg) was reached by 75.5 % of the patients. The mean dosage at the end of the study was 8 mg perindopril and 7.3 mg amlodipine. The results were consistent across subgroups of different previously received treatments and cardiovascular risks. Regarding laboratory findings, the reduction of total cholesterol from 5.67 to 5.21 mmol/L and that of LDL cholesterol from 3.18 to 2.83 mmol/L (p<0.001 for both) were of clinical importance. Eighty-five percent of the patients evaluated the way they felt themselves as excellent or improved. No serious adverse events were reported. Conclusion - Perindopril-amlodipine fixed combination can be administered effectively and safely to a large population of hypertensive patients who do not reach target blood pressure values.]

[TRIPTAN THERAPY OF MIGRAINE]

UNGUREAN Aurélia, TAJTI János, VÉCSEI László

[Migraine sufferers in Hungary present a major epidemiological challenge with about 12% of the population affected. Authors have reviewed an extensive body of internationally published literature relative to the 5-hydroxi-triptamin receptor agonists such as the triptans. While summarising most relevant data with a view to enable physicians to choose the most effective therapy for an individual, the article also discusses the prevailing questions of efficacy, tolerability and safety. For those patients with differential-diagnostic difficulties referrals should be made to the specialized 'headache centers' of neurological departments.]
