OBJECTIVES To develop recommendations for the management of adult and paediatric lupus nephritis (LN). METHODS The available evidence was systematically reviewed using the PubMed database. A modified Delphi method was used to compile questions, elicit expert opinions and reach consensus. RESULTS Immunosuppressive treatment should be guided by renal(More)
This study aimed to estimate the overall HCV genotype distribution and to reconstruct the HCV genotype-specific incidence in Greece during the recent decades. It also focused at the identification of genotype 4 subtype variability in Greek isolates. A total of 1686 chronically infected HCV patients with detectable serum HCV RNA by RT-PCR, belonging to(More)
OBJECTIVE Autoreactive B cells play a key role in tissue injury in systemic autoimmune disease, and therefore a treatment resulting in B cell depletion could have benefit. This open-label study was undertaken to evaluate the efficacy of the anti-CD20 monoclonal antibody rituximab in the treatment of lupus nephritis. METHODS Lupus patients with active(More)
OBJECTIVE Cerebral blood flow tests have increasingly been advocated for the confirmation of brain death (BD). Angiography has been considered the gold standard in the diagnosis of BD but is invasive. We validated transcranial color Doppler ultrasonography (TCD) to confirm BD by comparing it to angiography. PATIENTS AND METHODS Forty patients experienced(More)
PURPOSE To evaluate the efficacy of percutaneous angioplasty and stenting in cases of artery stenosis of the transplanted kidney or proximal iliac artery stenosis causing transplant dysfunction and/or increase of the arterial blood pressure. MATERIALS AND METHODS Between January 1999 and June 2007, we evaluated 24 patients who had undergone renal(More)
OBJECTIVE To evaluate the safety and efficacy of mycophenolate mofetil (MMF) treatment in patients with lupus nephritis. METHODS Eighteen patients with biopsy-proven lupus nephritis (17 females, one male; mean age 31.6 yr; mean lupus duration 92 months; mean duration of nephritis 57 months; nine with focal proliferative glomerulonephritis, three with(More)
Τhe clinical significance of de novo post-transplant anti-HLA donor-specific antibodies (DSA) was evaluated using 4241 serum samples collected between 2000 and 2007 from 597 renal transplant recipients. Patients transplanted before December 1996 (n = 77) were included in the historic group and those transplanted thereafter (n = 520) were included in the(More)
Balkan endemic nephropathy (BEN), originally described in the late 1950s as a chronic tubulointerstitial kidney disease, is identified by its unique epidemiological features. The most remarkable characteristic of BEN is the focal topographical nature that characterizes its occurrence at the global, national, and even household level. BEN affects only(More)
INTRODUCTION Renal hemorrhage is a major life-threatening condition that can be caused by trauma, operation, biopsy, as well as sudden spontaneous rupture of renal tumors or aneurysms. We report our experience with superselective segmental renal artery catheterization and embolization as therapeutic options for such cases. PATIENTS AND METHODS Over the(More)
Modern immunosuppressive regimens reduce the acute rejection rate by combining a cornerstone immunosuppressant like tacrolimus or cyclosporine with adjunctive agents like corticosteroids, mycophenolate mofetil (MMF) or azathioprine, often associated with untoward side effects. A 6-month randomized study was conducted in 47 European centers. Triple therapy(More)
