We have recently described heterogeneity in renal structure in non-insulin-dependent diabetic patients (NIDDM) with microalbuminuria (MA; defined as albumin excretion rate from 20 to 200 micrograms/min). Thus, at variance with IDDM patients, "typical" diabetic glomerulopathy by light microscopy is observed only in a third of NIDDM with MA (Category II,(More)
In order to analyze the role of phagocytic cells in experimental antitubular basement membrane (TBM) antibody-mediated nephritis, Hartley guinea pigs (GP) were immunized with rabbit tubular basement membrane (TBM) in complete Freund's adjuvant and pertussis vaccine. Renal tissue was obtained 10 to 15, 15 to 25, and 25 to 35 days after the start of(More)
A metabolic study was performed in 28 patients with bilateral recurrent calcium-containing renal staghorn calculi and chronic pyelonephritis ("obstructive nephropathy"). Fourteen had normal GFR and 14 mild renal insufficiency. Ten normal subjects were used as controls. Under basal conditions, polyuria and negative sodium balance were commonly observed in(More)
Immunohistologic studies were performed on autopsy tissues of 2 patients with systemic lupus erythematosus. All tissues examined--the kidney, lung, spleen, liver, intestine, peritoneum, and choroid plexus--contained immune deposits. Antinuclear antibody concentration in immunoglobulin G eluted from lung and spleen tissue was higher than in serum(More)
Urinary excretion of gamma-glutamyl transpeptidase, angiotensin I converting enzyme, beta-galactosidase and N-acetyl-beta-glucosaminidase was evaluated in 30 patients with idiopathic calcium oxalate urolithiasis. Higher than normal values were observed and the excretory enzyme pattern suggested tubular damage in patients with stones. A parallel study in the(More)
To determine whether bronchoalveolar lavage reflects the histologic aspects of the lung histology in patients with sarcoidosis and hypersensitivity pneumonitis, cells recovered from lavage fluid were compared with tissue sections from transbronchial lung biopsies in 33 patients. The evaluation of cellular types and their topographic distribution in situ was(More)
The interactions between two essential metals, Cu and Zn, and the localization and concentration of metallothionein have been studied in rat liver and kidney. Rats receiving daily intraperitoneal injections of Cu for 3 days, or Zn for 2 days, or Cu for 3 days followed by Zn for 2 days, were sacrificed 24, 72, 120 h after the final injection. Our data(More)
OBJECTIVE The objective of this review was to define a core set of recommendations for the treatment of HCV-associated mixed cryoglobulinemia syndrome (MCS) by combining current evidence from clinical trials and expert opinion. METHODS Expert physicians involved in studying and treating patients with MCS formulated statements after discussing the(More)
Sarcoidosis is a multisystem disease characterized by enhanced immune responses at sites of involvement. For this reason, an immunohistological study using monoclonal antibodies against T-cell subpopulations was carried out in order to evaluate the topographic distribution of immunocompetent cells in tissue sections obtained from a variety of involved(More)
