However, it is unknown if these molecules contribute to IS pathophysiology in humans, and might be of use as biomarkers for IS risk and severity. This study aimed to identify predictors of altered FXI and FXII levels and to determine whether there are differences in the levels of these coagulation factors between acute cerebrovascular events and chronic cerebrovascular disease (CCD). Methods: In this case-control study, 116 patients with acute ischemic stroke (AIS) or transitory ischemic attack (TIA), 117 patients with CCD, and 104 healthy volunteers (HVs) were enrolled between 2010 and 2013 at our University hospital. Blood sampling was undertaken once in the CCD and HV groups and on days 0, 1, and 3 after stroke onset in patients with AIS or TIA. Correlations between serum FXI and FXII levels and demographic and clinical parameters were tested by linear regression and analysis of variance. Results: The mean age of AIS/TIA patients was 70 ± 12. Baseline clinical severity measured with NIHSS and Barthel Index was 4.8 ± 6.0 and 74 ± 30, respectively. More than half of the patients had an AIS (58\%). FXI levels were significantly correlated with different leukocyte subsets (p < 0.05). In contrast, FXII serum levels showed no significant correlation (p > 0.1). Neither FXI nor FXII levels correlated with CRP (p > 0.2). FXII levels were significantly higher in patients with CCD compared with those with AIS/TIA (mean ± SD 106 ± 26\% vs. 97 ± 24\%; univariate analysis: p < 0.05); these differences did not reach significance in multivariate analysis adjusted for sex and age. FXI levels did not differ significantly between study groups. Sex and age were significantly associated with FXI and/or FXII levels in patients with AIS/TIA (p < 0.05). In contrast, no statistical significant influence was found for treatment modality (thrombolysis or not), pre-treatment with platelet inhibitors, and severity of stroke. Conclusions: In this study, there was no differential regulation of FXI and FXII levels between disease subtypes but biomarker levels were associated with patient and clinical characteristics. FXI and FXII levels might be no valid biomarker for predicting stroke risk.}, language = {en} } @article{SchneiderGutjahrLengsfeldRitzetal.2014, author = {Schneider, Andreas and Gutjahr-Lengsfeld, Lena and Ritz, Eberhard and Scharnagl, Hubert and Gelbrich, G{\"o}tz and Pilz, Stefan and Macdougall, Iain C. and Wanner, Christoph and Drechsler, Christiane}, title = {Longitudinal Assessments of Erythropoietin-Stimulating Agent Responsiveness and the Association with Specific Clinical Outcomes in Dialysis Patients}, series = {Nephron Clinical Practice}, volume = {128}, journal = {Nephron Clinical Practice}, number = {1-2}, issn = {1660-2110}, doi = {10.1159/000367975}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-196511}, pages = {147-152}, year = {2014}, abstract = {Background: Dose requirements of erythropoietin-stimulating agents (ESAs) can vary considerably over time and may be associated with cardiovascular outcomes. We aimed to longitudinally assess ESA responsiveness over time and to investigate its association with specific clinical end points in a time-dependent approach. Methods: The German Diabetes and Dialysis study (4D study) included 1,255 diabetic dialysis patients, of whom 1,161 were receiving ESA treatment. In those patients, the erythropoietin resistance index (ERI) was assessed every 6 months during a median follow-up of 4 years. The association between the ERI and cardiovascular end points was analyzed by time-dependent Cox regression analyses with repeated ERI measures. Results: Patients had a mean age of 66 ± 8.2 years; 53\% were male. During follow-up, a total of 495 patients died, of whom 136 died of sudden death and 102 of infectious death. The adjusted and time-dependent risk for sudden death was increased by 19\% per 5-unit increase in the ERI (hazard ratio, HR = 1.19, 95\% confidence interval, CI = 1.07-1.33). Similarly, mortality increased by 25\% (HR = 1.25, 95\% CI = 1.18-1.32) and infectious death increased by 27\% (HR = 1.27, 95\% CI = 1.13-1.42). Further analysis revealed that lower 25-hydroxyvitamin D levels were associated with lower ESA responsiveness (p = 0.046). Conclusions: In diabetic dialysis patients, we observed that time-varying erythropoietin resistance is associated with sudden death, infectious complications and all-cause mortality. Low 25-hydroxyvitamin D levels may contribute to a lower ESA responsiveness.}, language = {en} } @phdthesis{Mathes2014, author = {Mathes, Denise Sandra}, title = {Die Rolle von T-Lymphozyten im myokardialen Reperfusionsschaden}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-110802}, school = {Universit{\"a}t W{\"u}rzburg}, year = {2014}, abstract = {Der Myokardinfarkt (MI) geh{\"o}rt nach wie vor zu den f{\"u}hrenden Todesursachen weltweit. Eine Minimierung der Infarktgr{\"o}ße, die durch die Dauer der Isch{\"a}mie bestimmt wird, ist wesentlich f{\"u}r das {\"U}berleben und die Lebensqualit{\"a}t des Myokardinfarkt-Patienten. Die Reperfusion stellt aktuell eine zentrale klinische Intervention dar, um den myokardialen Schaden einzugrenzen. Dennoch f{\"u}hrt die Reperfusion per se zu zus{\"a}tzlichem Schaden am Herzen. Somit ist die Erforschung neuer Strategien zur Minimierung des myokardialen Reperfusionsschadens international von Interesse. Die Pathophysiologie des myokardialen Reperfusionsschadens ist vielschichtig und einige Komponenten sind auch heute in ihrer Wirkweise noch nicht vollst{\"a}ndig mechanistisch verstanden. Die vorliegende Arbeit untersucht die Rolle von CD4+ T-Zellen und insbesondere deren Subpopulation der regulatorischen T-Zellen im myokardialen Reperfusionsschaden und stellt neue, auf T-Zellen abzielende, Therapien in Erg{\"a}nzung zur myokardialen Reperfusion vor. Zun{\"a}chst wurde eine Infiltration von T-Zellen in das Myokard nach Isch{\"a}mie-Reperfusion (I/ R) untersucht. Nach der Isch{\"a}mie-Reperfusion wurden infiltrierende CD4+ T-Zellen als quantitativ f{\"u}hrend und aktiviert identifiziert und erwiesen sich in der Infarktgr{\"o}ßenbestimmung als relevante Mediatoren des Reperfusionsschadens. CD25+Foxp3+ regulatorische T-Zellen (Treg) stellen eine Subpopulation von CD4+ T-Zellen mit immunsuppressiven Eigenschaften dar, die schnell und niederschwellig aktiviert werden k{\"o}nnen und kommen somit als zum Reperfusionsschaden beitragend in Frage. Mit Hilfe des DEREG (DEpletion of REGulatory T cells) -Mausmodells wurde gezeigt, dass regulatorische T-Zellen zum myokardialen Reperfusionsschaden beitragen; Treg-depletierte DEREG-M{\"a}use waren vor dem Reperfusionsschaden gesch{\"u}tzt und zeigten kleinere Infarktgr{\"o}ßen als die Kontrolltiere. Zudem wurde mittels Transferexperimenten gezeigt, dass f{\"u}r den Treg-vermittelten Reperfusionsschaden die Anwesenheit von CD25- konventionellen T-Zellen (Tconv) erforderlich ist. Regulatorische T-Zellen stellen also einen in der vorliegenden Arbeit identifizierten potentiellen Angriffspunkt zur Reduktion des myokardialen Reperfusionsschadens dar. Anhand von T-Zell-Rezeptor transgenen OT-II M{\"a}usen und MHC (Major Histocompatibility Complex) Klasse II Knockout (KO) Tieren wurde gezeigt, dass Autoantigenerkennung im myokardialen Reperfusionsschaden eine Rolle spielt. Zur vollen T-Zell-Aktivierung notwendig ist neben dem MHC Klasse II-Signalweg und Kostimulatoren auch das Molek{\"u}le CD154 (CD40L). Die Gabe eines inhibitorischen anti-CD154-Antik{\"o}rpers reduzierte die Infarktgr{\"o}ße in Wildtyp-Tieren sigifikant. Der myokardiale Reperfusionsschaden kann neben Zellen der adaptiven Immunit{\"a}t auch durch Neutrophile Granulozyten, Pl{\"a}ttchen oder Inflammation des Endothels verst{\"a}rkt werden. Knockout M{\"a}use mit einer Defizienz an CD4+ T-Zellen verf{\"u}gten {\"u}ber eine verbesserte Mikroperfusion. Mechanistisch war nach 24h Reperfusion die absolute Zellzahl an Neutrophilen Granulozyten im CD4 KO im Vergleich zu Wildtyp-M{\"a}usen unver{\"a}ndert; in Endothelzellen war die Regulation bestimmter Gene (VEGFα, TIMP-1 und Eng) nach I/ R im CD4 KO jedoch ver{\"a}ndert. Zusammengefasst zeigt die vorliegende Arbeit eine zentrale Rolle der Antigen-Erkennung durch den T-Zell-Rezeptor zur Aktivierung von CD4+ T-Zellen im myokardialen Reperfusionsschaden. In Anwesenheit von CD4+Foxp3+ T-Zellen ist der Reperfusionsschaden erh{\"o}ht.

Methods: The circle of experts was increased, general aspects were implemented and the state of the art was updated. Particular emphasis was dedicated to coronary heart diseases (CHD), heart rhythm diseases and heart failure because to date the evidence-based clinical knowledge is most advanced in these particular areas. Differences between men and women and over the life span were considered in the recommendations as were influences of cognitive capability and the interactive and synergistic impact of classical somatic risk factors on the affective comorbidity in heart disease patients. Results: A IA recommendation (recommendation grade I and evidence grade A) was given for the need to consider psychosocial risk factors in the estimation of coronary risks as etiological and prognostic risk factors. Furthermore, for the recommendation to routinely integrate psychosocial patient management into the care of heart surgery patients because in these patients, comorbid affective disorders (e.g. depression, anxiety and post-traumatic stress disorder) are highly prevalent and often have a malignant prognosis. A IB recommendation was given for the treatment of psychosocial risk factors aiming to prevent the onset of CHD, particularly if the psychosocial risk factor is harmful in itself (e.g. depression) or constrains the treatment of the somatic risk factors. Patients with acute and chronic CHD should be offered anti-depressive medication if these patients suffer from medium to severe states of depression and in this case medication with selective reuptake inhibitors should be given. In the long-term course of treatment with implanted cardioverter defibrillators (ICDs) a subjective health technology assessment is warranted. In particular, the likelihood of affective comorbidities and the onset of psychological crises should be carefully considered. Conclusions: The present state of the art paper presents an update of current empirical evidence in psychocardiology. The paper provides evidence-based recommendations for the integration of psychosocial factors into cardiological practice and highlights areas of high priority. The evidence for estimating the efficiency for psychotherapeutic and psychopharmacological interventions has increased substantially since the first release of the policy document but is, however, still weak. There remains an urgent need to establish curricula for physician competence in psychodiagnosis, communication and referral to ensure that current psychocardiac knowledge is translated into the daily routine.}, language = {en} } @article{LocatelliSpasovskiDimkovicetal.2014, author = {Locatelli, Francesco and Spasovski, Goce and Dimkovic, Nada and Wanner, Christoph and Dellanna, Frank and Pontoriero, Giuseppe}, title = {The effects of colestilan versus placebo and sevelamer in patients with CKD 5D and hyperphosphataemia: a 1-year prospective randomized study}, series = {Nephrology Dialysis Transplantation}, volume = {29}, journal = {Nephrology Dialysis Transplantation}, number = {5}, doi = {10.1093/ndt/gft476}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-121114}, pages = {1061-73}, year = {2014}, abstract = {BACKGROUND: This study compared the effects of short-term titrated colestilan (a novel non-absorbable, non-calcium, phosphate binder) with placebo, and evaluated the safety and efficacy of colestilan over 1 year compared with sevelamer, in patients with chronic kidney disease (CKD) 5D. METHODS: This prospective multicentre study comprised a 4-week phosphate binder washout period, a 16-week short-term, flexible-dose, treatment period (including a 4-week placebo-controlled withdrawal period) and a 40-week extension treatment phase. RESULTS: At Week 16 (the end of the 4-week placebo-controlled withdrawal period), serum phosphorus level was 0.43 mmol/L (1.32 mg/dL) lower with colestilan than placebo (P < 0.001; primary end point). Serum LDL-C level was also lower with colestilan than with placebo (P < 0.001). Both colestilan and sevelamer produced significant reductions from baseline in serum phosphorus levels (P < 0.001), maintained for 1 year, and the proportion of patients achieving target levels of ≤1.78 mmol/L (5.5 mg/dL) or ≤1.95 mmol/L (6.0 mg/dL) at study end were similar (65.3 and 73.3\%, respectively, for colestilan, and 66.9 and 77.4\%, respectively, for sevelamer). Serum calcium level remained stable in the colestilan group but tended to increase slightly in the sevelamer group (end-of-study increase of 0.035 mmol/L over baseline). Both binders produced similar reductions from baseline in LDL-C level (P < 0.001), and responder rates after 1 year, using a target of <1.83 mmol/L (70 mg/dL) or <2.59 mmol/L (100 mg/dL) were similar in both groups (50.7 and 85.3\% for colestilan and 54.0 and 80.6\% for sevelamer). Colestilan was generally well tolerated. CONCLUSIONS: Colestilan is effective and safe for the treatment of hyperphosphataemia in patients with CKD 5D, and affords similar long-term phosphorus and cholesterol reductions/responder rates to sevelamer.}, language = {en} } @article{SchickBaarFlemmingetal.2014, author = {Schick, Martin A. and Baar, Wolfgang and Flemming, Sven and Schlegel, Nicolas and Wollborn, Jakob and Held, Christopher and Schneider, Reinhard and Brock, Robert W. and Roewer, Norbert and Wunder, Christian}, title = {Sepsis-induced acute kidney injury by standardized colon ascendens stent peritonitis in rats - a simple, reproducible animal model}, series = {Intensive Care Medicine Experimental}, volume = {2}, journal = {Intensive Care Medicine Experimental}, number = {34}, doi = {10.1186/s40635-014-0034-x}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-126111}, year = {2014}, abstract = {Background Up to 50\% of septic patients develop acute kidney injury (AKI). The pathomechanism of septic AKI is poorly understood. Therefore, we established an innovative rodent model to characterize sepsis-induced AKI by standardized colon ascendens stent peritonitis (sCASP). The model has a standardized focus of infection, an intensive care set up with monitoring of haemodynamics and oxygenation resulting in predictable impairment of renal function, AKI parameters as well as histopathology scoring. Methods Anaesthetized rats underwent the sCASP procedure, whereas sham animals were sham operated and control animals were just monitored invasively. Haemodynamic variables and blood gases were continuously measured. After 24 h, animals were reanesthetized; cardiac output (CO), inulin and PAH clearances were measured and later on kidneys were harvested; and creatinine, urea, cystatin C and neutrophil gelatinase-associated lipocalin (NGAL) were analysed. Additional sCASP-treated animals were investigated after 3 and 9 days. Results All sCASP-treated animals survived, whilst ubiquitous peritonitis and significantly deteriorated clinical and macrohaemodynamic sepsis signs after 24 h (MAP, CO, heart rate) were obvious. Blood analyses showed increased lactate and IL-6 levels as well as leucopenia. Urine output, inulin and PAH clearance were significantly decreased in sCASP compared to sham and control. Additionally, significant increase in cystatin C and NGAL was detected. Standard parameters like serum creatinine and urea were elevated and sCASP-induced sepsis increased significantly in a time-dependent manner. The renal histopathological score of sCASP-treated animals deteriorated after 3 and 9 days. Conclusions The presented sCASP method is a standardized, reliable and reproducible method to induce septic AKI. The intensive care set up, continuous macrohaemodynamic and gas exchange monitoring, low mortality rate as well as the opportunity of detailed analyses of kidney function and impairments are advantages of this setup.

Here, we provide an appraisal of electroporation as a means to introduce either short-hairpin RNA expression vectors or synthesised siRNAs into MM cells. We found that electroporation using siRNAs was much more efficient than previously anticipated on the basis of transfection efficiencies deduced from EGFP-expression off protein expression vectors. Such knowledge can even confidently be exploited in "hard-to-transfect" MM cell lines to generate large numbers of transient knockdown phenotype MM cells.

Allerdings kann aufgrund des massiven Spenderorganmangels eine Transplantation h{\"a}ufig nur nach langer Wartezeit realisiert werden. Ein m{\"o}glicher Ausweg besteht in der Transplantation von Organen, die erweiterte Spenderkriterien aufweisen. Um das Outcome nach Transplantation eines solchen Organs mit hoher Genauigkeit und m{\"o}glichst standardisiert vorhersagen zu k{\"o}nnen, wurden an großen US-amerikanischen Patientenkollektiven auf dem Boden multivariater Analysen post hoc sogenannte Donor-Scores erstellt. In der vorliegenden Arbeit wurde nun am Beispiel des Nierentransplantationsprogramm W{\"u}rzburg {\"u}berpr{\"u}ft, ob derartige Score-Systeme auch an einem mitteleurop{\"a}ischen Patientenkollektiv ausreichend Vorhersagekraft aufweisen.

(40) retrospektiv auf das Spenderkollektiv f{\"u}r W{\"u}rzburger Organempf{\"a}nger angewendet und die Spender entsprechend eingruppiert.

Da nur sehr wenig Organe in die prognostisch besonders ung{\"u}nstigen Spendergrade eingeteilt wurden ( DDS° D: n= 15 und Schold °V: n = 13), konnte hier keine signifikante Korrelation beobachtet werden.
