Abstract

Zusammenfassung: Hintergrund: Die anatomische Darstellung und Erfassung m�glicher Anomalien der Nierengef��e und Ureteren ist f�r die Planung einer Lebendnierenspende von essenzieller Bedeutung. Die vorliegende Untersuchung soll die Wertigkeit der nichtinvasiven Evaluation mit der 64-Zeilen-Multidetektor-CT untersuchen. Material und Methoden: In die Auswertung wurden 63 Lebendnierenspender (LNS) eingeschlossen, die im Zeitraum 12.2004 bis 01.2007 mit der CT pr�operativ untersucht wurden. Die Untersuchungen erfolgten mit einem Somatom-Sensation-Cardiac-64 (Siemens Medical Solutions, Deutschland). Neben einer CT-Angiographie (CTA) wurden eine ven�se Phase des Abdomens und eine Sp�tphase nach 15 min in Low-dose-Technik f�r die CT-Urographie (CTU) durchgef�hrt. Die radiologischen Befunde wurden mit dem intraoperativen Befund oder in 2 F�llen mit der konventionellen Angiographie verglichen, au�erdem wurden Sensitivit�t, Spezifit�t, negativer und positiver Vorhersagewert ermittelt. Ergebnisse: Bei den ausgewerteten 63 LNS (31 weibliche, 32 m�nnliche) erreichte die CTA eine Sensitivit�t von 100% f�r die Arterien und Polarterien und 98,3% f�r die Nierenvenenanatomie. Die Low-dose-CTU erreichte ebenfalls eine Sensitivit�t von 100%. Schlussfolgerung: Die Ergebnisse zeigen, dass eine nichtinvasive pr�operative Planung bei potenziellen Lebendnierenspendern anhand einer 64-Zeilen-Multidetektor-CT im Sinne des „On-stop-Shopping“ zuverl�ssig m�glich ist.

Abstract

Granzyme A is a serine protease expressed by populations of human and mouse natural killer cells and activated CD4+ and CD8+ cytotoxic lymphocytes; its expression marks a subset of inflammatory cells in allografts, autoimmune diabetes, and a number of other inflammatory lesions. In order to describe more completely the correlation between granzyme A expression and the presence of in vivo cytolytic effects, we grafted allogeneic rat hearts with vascular anastomoses in a heterotopic location, and treated the hosts with either cyclosporine, anti-CD4 monoclonal antibody (MRC OX38), or no therapy. The grafts were evaluated by palpation for cardiac functions, by immunohistochemistry for CD4/CD8 expression, by hematoxylin-and-eosin staining for inflammatory infiltration, and by in situ hybridization for granzyme A expression. The appearance of granzyme A+ cells in untreated allografts preceded both functional and standard histopathological and immunohistochemical evidence of graft rejection by two days. In donor-recipient combinations where cyclosporine and anti-CD4 treatments allowed indefinite allograft survival, the allografts showed minimal numbers of granzyme A+ cells, whether cellular infiltrates developed or not. The number of granzyme A+ cells present in the cardiac allografts in treated and untreated animals correlated with either current or impending episodes of rejection. The early time course of granzyme A expression suggests that it can be used as an early and reliable marker of graft rejection.

Abstract

BACKGROUND: There are few anecdotal reports of circulating antineutrophil cytoplasmic autoantibodies (ANCAs) in patients with immunoglobulin A (IgA) nephropathy. STUDY DESIGN: Retrospective case series. SETTING & PARTICIPANTS: We studied 8 patients with crescentic IgA nephropathy associated with ANCAs against myeloperoxidase (n = 5) and proteinase 3 (n = 3) followed up for 2.4 +/- 1.7 years. They were compared with 26 patients with IgA nephropathy with > 10% crescentic glomeruli, but negative for ANCAs. OUTCOMES: We analyzed clinical and histologic features of patients and their response to treatment. MEASUREMENTS: Screening for ANCAs was performed using indirect immunofluorescence, and positive results were verified using enzyme-linked immunosorbent assay. RESULTS: All patients with crescentic IgA nephropathy and positive for ANCAs, compared with only one-third of ANCA-negative patients, presented with the clinical syndrome of rapid progressive glomerulonephritis. ANCA-positive patients reached a higher peak serum creatinine level within the first 3 months (4.2 +/- 2.2 vs 2.5 +/- 1.9 mg/dL; estimated glomerular filtration rate, 19.3 +/- 10.2 vs 45.9 +/- 30.1 mL/min/1.73 m(2)). ANCA-positive patients with IgA nephropathy had a higher percentage of crescentic glomeruli (54.3% +/- 18%) compared with ANCA-negative patients with crescentic IgA nephropathy (34.5% +/- 26%). ANCA-positive patients were treated using cyclophosphamide and corticosteroids. Kidney function improved in all these patients: serum creatinine level decreased from the peak of 4.2 +/- 2.2 to 1.7 +/- 0.7 mg/dL at the end of follow up (estimated glomerular filtration rate, 19.3 +/- 10.2 to 44.6 +/- 11.1 mL/min/1.73 m(2)). In contrast, no significant improvement was achieved in ANCA-negative patients. CONCLUSION: Patients with IgA nephropathy, crescents, and positive for ANCAs represent a clinical entity with a diverse more exaggerated clinical and histologic picture. However, disease in these patients responded well to aggressive immunosuppressive therapy. [ABSTRACT FROM AUTHOR]
