Glomerular hyperfiltration is a phenomenon that can occur in various clinical conditions including kidney disease. No single definition of glomerular hyperfiltration has been agreed upon, and the pathophysiological mechanisms, which are likely to vary with the underlying disease, are not well explored. Glomerular hyperfiltration can be caused by afferent(More)
BACKGROUND The epidemic of obesity and diabetes is increasing within the USA and worldwide. We have previously shown that body mass index has increased significantly in autosomal dominant polycystic kidney disease (ADPKD) subjects seen at our center in more recent years. However, the impact of Type II diabetes in ADPKD patients has not been well studied. (More)
OBJECTIVE Autosomal dominant polycystic kidney disease is the most frequent life-threatening hereditary disease. The study objective was to assess whether the clinical characteristics of patients with autosomal dominant polycystic kidney disease who are referred to a major autosomal dominant polycystic kidney disease center have changed over time. METHODS(More)
BACKGROUND AND OBJECTIVES The purpose of this study was to determine whether glomerular hyperfiltration (GH) occurring early in autosomal dominant polycystic kidney disease (ADPKD) is indicative of more rapid disease progression in children. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS One hundred eighty children with ADPKD (ages 4 to 18 years) with(More)
Autosomal dominant polycystic kidney disease is the most frequent life-threatening hereditary disease. Prognostic factors for progressive renal impairment have been identified such as gender, race, age, proteinuria, hematuria, hypertension. Hypertension is the only risk factor for renal dysfunction in autosomal dominant polycystic kidney disease, which is(More)
Chronic inflammation is highly prevalent in patients on hemodialysis (HD), as evidenced by increased levels of C-reactive protein (CRP). We compared CRP to high-sensitivity C-reactive protein (hs-CRP) to determine whether it has any clinical implications and prognostic significance in terms of mortality. CRP was measured using a standard immunoturbidometric(More)
Studies looking at the type of pretransplantation renal replacement therapy on graft and patient survivals after kidney transplantation have produced conflicting results. Therefore, we studied the effect of pretransplantation dialysis modality (peritoneal dialysis [PD] or hemodialysis [HD]) on transplant outcomes. We performed a retrospective study of 78(More)
Sirolimus has been associated with high-range proteinuria when used in replacement of calcineurin inhibitors in renal transplant recipients with chronic allograft nephropathy (CAN). Primary FSGS was demonstrated previously in some such patients, but the coexistence of CAN lesions made the interpretation uneasy. However, nephrotic syndrome and FSGS were(More)
BACKGROUND Hyperuricemia has been implicated in the development and progression of chronic kidney disease, both in animal experiments and in clinical studies. As a potentially modifiable risk factor, we examined whether serum uric acid levels correlate with early hypertension, kidney volume and progression to end-stage renal disease (ESRD) in(More)
BACKGROUND This study evaluates the prevalence of cardiovascular events in autosomal dominant polycystic kidney disease (ADPKD) patients. METHODS We distributed surveys to 1,439 subjects from our ADPKD research database. In total, 426 subjects completed and returned surveys; 7 of these were from children and were excluded from the study. RESULTS The(More)
