Automatizáltan mérhető biomarkerek az akut myocardialis infarctus diagnosztikájában

INTRODUCTION: Cardiac biomarkers have a prominent role in the diagnosis of acute myocardial infarction. AIM: The aim of the authors was to study the diagnostic effectiveness of automated measurement of cardiac biomarkers. METHOD: Myeloperoxidase, high-sensitivity C-reactive protein, myoglobin, heart-type fatty acid binding protein, creatine kinase, creatine kinase MB, high-sensitivity troponin I and T were measured. RESULTS: The high-sensitivity troponin I was the most effective (area under curve: 0.86; 95% confidence interval: 0.77-0.95; p<0.001) for the diagnosis of acute myocardial infarction. Considering a critical value of 0.35 ng/mL, its sensitivity and specificity were 81%, and 74%, respectively. Combined evaluation of the high-sensitivity troponin T and I, chest pain, and the electrocardiogram gave the best results for separation of acute myocardial infarction from other diseases (correct classification in 62.5% and 98.9% of patients, respectively). CONCLUSIONS: Until a more sensitive and specific cardiac biomarker becomes available, the best method for the diagnosis of acute myocardial infarction is to evaluate electrocardiogram and biomarker concentration and to repeat them after 3-6 hours

Veseérintettség májátültetés során

Introduction: In liver cirrhosis renal function decreases as well. Hepatorenal syndrome is the most frequent cause of the decrease, but primary kidney failure, diabetes mellitus and some diseases underlying endstage liver failure (such as hepatitis C virus infection) can also play an important role. In liver transplantation several further factors (total cross-clamping of vena cava inferior, polytransfusion, immunosuppression) impair the renal function, too. Aim: The aim of this study was to analyse the changes in kidney function during the first postoperative year after liver transplantation. Method: Retrospective data analysis was performed after primary liver transplantations (n = 319). Results: impaired preoperative renal function increased the devepolment of postoperative complications and the first year cumulative patient survival was significantly worse (91,7% vs 69,9%; p<0,001) in this group. If renal function of the patients increased above 60 ml/min/1,73 m2 after the first year, patient survival was better. Independently of the preoperative kidney function, 76% of the patients had impaired kidney function at the first postoperative year. In this group, de novo diabetes mellitus was more frequently diagnosed (22,5% vs 9,5%; p = 0,023). Conclusions: Selection of personalized immunosuppressive medication has a positive effect on renal function. Orv. Hetil., 2013, 154, 1018-1025

Hepatitis C-vírus-fertőzés kiújulása májátültetés után. Mi változott az elmúlt 10 évben?

Introduction: Management of hepatitis C virus recurrence is a challenge after liver transplantation. Aim: The aim of the authors was to analyse the outcome of liver transplantation performed in hepatitis C virus positive patients during the past ten years and to compare recent data with a previous report of the authors. Method: The authors retrospectively evaluated the data (donors, recipients, perioperative characteristics, patient and graft survival, serum titer of hepatitis C virus RNA, histology) of 409 patients who underwent liver transplantation between 2003 and 2012. Results: 156 patients were transplanted due to hepatitis C virus associated liver cirrhosis (38%). Worse outcome was observed in these patients in comparison to hepatitis C virus negative recipients. The cumulative patient survival rates at 1, 5, and 10 year were 80%, 61%, 51% in the hepatitis C virus positive group and 92%, 85%, 79% in the hepatitis C virus negative group, respectively (p<0.001). The cumulative graft survival rates at 1, 5 and 10 year were 79%, 59% and 50% in hepatitis C virus positive and 89%, 80% and 70% in hepatitis C virus negative patients (p<0.001). Hepatitis C virus recurrence was observed in the majority of the patients (132 patients, 85%), mainly within the first year (83%). The authors observed recurrence within 6 months in 71 patients (56%), and within 3 months in 26 patients (20%). The mean hepatitis C virus recurrence free survival was 243 days. Higher rate of de novo diabetes was detected in case of early recurrence. The cumulative patient survival rates at 1, 3, 5, 10 years were 98%, 89.5%, 81% and 65% when hepatitis C virus recurrence exceeded 3 months and 64%, 53%, 30.5% and 30.5% in patients with early recurrence (p<0.001). Conclusions: Poor outcome of liver transplantation in hepatitis C virus positive patients is still a challenge. Hepatitis C virus recurrence is observed earlier after liver transplantation in comparison with a previous report of the authors. De novo diabetes occurs more frequently in case of early recurrence. Despite an immediate start of antiviral treatment, early recurrence has a significant negative impact on the outcome of transplantation. Orv. Hetil., 2013, 154, 1058-1066

De novo diabetes és májátültetés, különös tekintettel a hepatitis C-vírus kiújulására = New-onset diabetes mellitus after liver transplantation

A de novo diabetes mellitus a májátültetés gyakori szövődménye. Célkitűzés: A de novo diabetes gyakoriságát, jelentőségét és a kockázati tényezők szerepét vizsgáltuk. Módszer: 1995 és 2009 között 310 májátültetett beteg adatait dolgoztuk fel retrospektív módszerrel. De novo diabetest állapítottunk meg, ha az éhomi vércukor a 3. posztoperatív hónapon túl ismételten >6,8 mmol/l volt, és/vagy a májátültetés után tartós, a 3. posztoperatív hónapot meghaladóan is fenntartott antidiabetikus terápia indult. Eredmények: De novo diabetes a betegek 20%-ánál (63 beteg) alakult ki. A de novo és a kontrollcsoport között az alábbiakban találtunk különbséget. Donor-testtömegindex (24±3 vs. 22,4±3,6 kg/m 2 , p = 0,003), férfi nem (58% vs. 33%, p = 0,002). Recipienséletkor (47,6±7,2 vs. 38,3±14,6 év, p<0,001), -testtömegindex (26,7±3,8 vs. 23,3±5,6 kg/m 2 , p<0,001), férfi nem (60% vs. 44%, p = 0,031). A de novo diabetesesek csoportjában a betegek 66%-át HCV talaján kialakult cirrhosis miatt transzplantálták, a kontrollcsoportban ez csak 23% volt (p<0,001). Az 1, 3, 5 és 8 éves kumulatív betegtúlélés a kontrollcsoportban 95%, 91%, 88% és 88%, a de novo csoportban a megfelelő értékek 87%, 79%, 79% és 64% (p = 0,011). Az 1, 3, 5 és 8 éves kumulatív grafttúlélés a kontrollcsoportban 92%, 87%, 86% és 79%, a de novo csoportban a megfelelő értékek 87%, 79%, 79%, 65% (p = NS). Azoknál a betegeknél, akiknél a C-vírus korai (6 hónapon belüli) kiújulását észleltük, többségben de novo diabetes is kialakult (74% vs. kontroll 26%, p = 0,03). A betegek 53%-ában észleltünk tízszeres vírustiter-emelkedést a műtét utáni 6 hónapon belül a preoperatív értékhez viszonyítva diabetes kialakulása esetén, a kontrollnál ez 20% volt (p = 0,028). A de novo csoportban magasabb volt az átlagos (Ishak-Knodell) fibrosis score az antivirális kezelés megkezdését követően 1 évvel (2,05±1,53 vs. 1,00±1,08, p = 0,039). Következtetés: Májátültetést követő de novo diabetes kockázati tényezői az időskor, elhízás, férfi nem és a C-vírus okozta cirrhosis. Víruspozitív betegek körében a korai rekurrencia, súlyosabb viraemia és az antivirális kezelés ellenére kialakuló súlyosabb fibrosis összefügg a de novo diabetes kialakulásával. | New-onset diabetes is a common complication after liver transplantation. Aim: We aimed to analyze the incidence and rate of known risk factors and the impact of new-onset diabetes mellitus on postoperative outcome. Methods: We retrospectively evaluated the files of 310 patients who underwent liver transplantation between 1995 and 2009. Definition of new-onset diabetes included: repeated fasting serum glucose >6.8 mmol/l and/or sustained antidiabetic therapy that was present 3 months after transplantation. Results: New-onset diabetes occurred in 63 patients (20%). Differences between the new-onset and the control group were the donor body mass index (24±3 vs. 22.4±3.6 kg/m 2 , p = 0.003), donor male gender (58% vs. 33%, p = 0.002), and recipient age (47.6±7.2 vs. 38.3±14.6 year, p<0.001), body mass index (26.7±3.8 vs. 23.3±5.6 kg/m 2 , p<0.001), male gender (60% vs. 44%, p = 0.031). The 66% of patients with new-onset diabetes were transplanted with cirrhosis caused by hepatitis C virus infection, while in the control group the rate was 23% (p<0.001). Cumulative patient survival rates at 1, 3, 5 and 8 year were 95%, 90.6%, 88% and 88% in the control group, and 87%, 79%, 79% and 64% in the de novo group, respectively (p = 0.011). Cumulative graft survival rates at 1, 3, 5 and 8 year in the control group were 92%, 87%, 86% and 79%, in the de novo diabetes group the rates were 87%, 79%, 79%, 65%, respectively (p = NS). In case of early recurrence (in 6 months), majority of patients developed new-onset diabetes (74% vs. control 26%, p = 0.03). More patients had more than 10 times higher increase of the postoperative virus titer correlate to the preoperative titer in the de novo diabetes group (53% vs. 20%, p = 0.028). Mean fibrosis score was higher in new-onset group one year after the beginning of antiviral therapy (2.05±1.53 vs. 1.00±1.08, p = 0.039). Conclusions: Risk factors for new-onset diabetes after transplantation are elder age, obesity, male gender and cirrhosis due to hepatitis C infection. The early recurrence, viremia and more severe fibrosis after antiviral therapy have an impact on the occurrence of new-onset diabetes in hepatitis C positive patients

Hét, becsült glomerulusfiltrációs ráta egyenletének összehasonlítása vesebetegekben [Comparison of seven estimated glomerular filtration rate equations in kidney patients]

Introduction: The degree of glomerular filtration rate determines the stages of chronic renal disease and, therefore, knowledge on its estimation is essential. Aims: Two standardized creatinine based estimated glomerular filtration rate equations and five equations based on the immunoturbidimetric determination of cystatin C were compared. Methods: The distribution of the analytes and the equations, their relations, as well as the differences among the estimated glomerular filtration rates and their chronic kidney disease stages assignments were studied. Results: The equations based on cystatin C classified more patient into stage 1, while the creatinine based ones more into stages 2, 3 and 4. The equations published as Grubb1, Grubb2 and Larsson classified more patients while the equations created by Tan and Sjostrom classified fewer into stage 5 compared to the creatinine based equations. The equations of Grubb1 and Grubb2 resulted in the most similar stage assignment. The occurence of stages between 3 and 5 was the lowest using the equation of Sjostrom. Conclusions: The different equations for the estimation of glomerular filtration rate modify significantly the chronic kidney disease stage assignment which may have an influence on the treatment and outcome measures of the patients.

Hét, becsült glomerulusfiltrációs ráta egyenletének összehasonlítása vesebetegekben | Comparison of seven estimated glomerular filtration rate equations in kidney patients

Bevezetés: Krónikus vesebetegségben elengedhetetlen a glomerulusfiltrációs ráta ismerete, mivel annak mértéke határozza meg a stádiumokat, és iránymutató a kezelés szempontjából. Célkitűzés: A szerzők két, a standardizált kreatininen, valamint öt immunturbidimetriás cisztatin-C-meghatározáson alapuló becsült glomerulusfiltrációs ráta egyenletét vizsgálták. Módszer: Az analitok és az egyenletek eloszlását, kapcsolataikat, a becsült glomerulusfiltrációs ráták közötti különbségeket és stádiumbesorolásaikat tanulmányozták. Eredmények: A cisztatin-C-képletek több beteget soroltak az 1-es stádiumba, míg a kreatinines képletek a 2-es, 3-as és 4-esbe. Az 5. stádiumba a Grubb1-, Grubb2- és Larsson-képletek több, míg a Tan- és Sjöström-képletek kevesebb beteget soroltak, mint a kreatinines képletek. Legjobban a Grubb1- és Grubb2-egyenletek stádiumbesorolásai hasonlítottak egymásra. A 3–5. stádiumok legritkábban a Sjöström-képlet esetében fordultak elő. Következtetések: A különböző képletekkel számolt becsült glomerulusfiltrációs ráták szignifikánsan befolyásolhatják a stádiumbeosztást, így a betegek kezelését és kilátásaik becslését is. Orv.
