BACKGROUND The aim of this multicentre collaborative study was to compare the progression of renal disease in children and adults with Henoch-Schönlein purpura (HPS) nephritis selected on the basis of IgA-dominant renal deposits and biopsy material available for review. METHODS The analysis was performed in 152 patients (95 adults and 57 children < 16(More)
IgA nephropathy is the most common glomerular disease worldwide, yet there is no international consensus for its pathological or clinical classification. Here a new classification for IgA nephropathy is presented by an international consensus working group. The goal of this new system was to identify specific pathological features that more accurately(More)
Diabetes is the leading cause of ESRD because diabetic nephropathy develops in 30 to 40% of patients. Diabetic nephropathy does not develop in the absence of hyperglycemia, even in the presence of a genetic predisposition. Multigenetic predisposition contributes in the development of diabetic nephropathy, thus supporting that many factors are involved in(More)
BACKGROUND The risks associated with performing a percutaneous renal biopsy have substantially decreased in the past two decades because of technical advances in the method. However, bleeding complications still occur, resulting in increased hospital stay and treatment costs. METHODS We investigated the predictive value of demographics (age, gender),(More)
BACKGROUND Stratum 2 of the Ramipril Efficacy in Nephropathy (REIN) study has already shown that in patients with chronic nephropathies and proteinuria of 3 g or more per 24 h, angiotensin-converting enzyme (ACE) inhibition reduced the rate of decline in glomerular filtration and halved the combined risk of doubling of serum creatinine or end-stage renal(More)
BACKGROUND Obstructive nephropathy is characterized at the histologic level by tubular atrophy and interstitial monocyte infiltration. The molecular mechanisms underlying these histologic changes are still poorly defined. Epidermal growth factor (EGF) produced by tubular cells seems to play a pivotal role in the modulation of tubular cell growth, while(More)
Pathological classifications in current use for the assessment of glomerular disease have been typically opinion-based and built on the expert assumptions of renal pathologists about lesions historically thought to be relevant to prognosis. Here we develop a unique approach for the pathological classification of a glomerular disease, IgA nephropathy, in(More)
The worldwide medical literature was reviewed to determine whether the prevalence, clinical presentation, and immunohistologic findings of primary IgA nephropathy were related to geographic areas. A total of 68 reports containing detailed clinical histories and laboratory findings were analyzed. The selected articles were grouped according to their(More)
PURPOSE This report describes data collected by the Italian Registry of Renal Biopsies (IRRB) (E mail http://www.teseo.it/nephrology/irrb), which includes 15461 renal biopsies (RB) performed over a period of 7 years (1987-1993). METHODS From 1987 to 1988, the Registry recorded only the histological diagnosis of 3686 RB, whereas beginning in 1989,(More)
T helper type 1 (Th1)-type CD4(+) antitumor T cell help appears critical to the induction and maintenance of antitumor cytotoxic T lymphocyte (CTL) responses in vivo. In contrast, Th2- or Th3/Tr-type CD4(+) T cell responses may subvert Th1-type cell-mediated immunity, providing a microenvironment conducive to disease progression. We have recently identified(More)
