Contrast-induced nephropathy: pharmacology, pathophysiology and prevention
Modern iodinated contrast media (CM) consist of one or two tri-iodobenzene rings. They differ from each other in the composition of the side chains, creating different molecules and thus different brand substances. After intravascular administration, all CM are distributed rapidly into intravascular and extracellular fluids. They are eliminated solely by glomerular filtration. In patients with ...
متن کاملContrast-induced nephropathy: pathophysiology and preventive strategies.
Contrast-induced nephropathy is the third most common cause of hospital-acquired renal failure, after decreased renal perfusion and nephrotoxic medications. Identification of patients at risk and implementation of preventive strategies can decrease the incidence of this nephropathy. Prevention strategies focus on counteracting vasoconstriction, enhancing blood flow through the nephron, and prov...
متن کاملThe pathophysiology of IgA nephropathy.
Here we discuss recent advances in understanding the biochemical, immunologic, and genetic pathogenesis of IgA nephropathy, the most common primary glomerulonephritis. Current data indicate that at least four processes contribute to development of IgA nephropathy. Patients with IgA nephropathy often have a genetically determined increase in circulating levels of IgA1 with galactose-deficient O-...
متن کاملContrast-Induced Nephropathy Following CT Scan and Its Associated Factors
Background and purpose: Contrast-induced nephropathy (CIN) as a common complication of administration of contrast media (CM) is a major source of hospital morbidity and mortality. The aim of this study was to determine the incidence of CIN after contrast-enhanced CT scan and identifying the related risk factors. Materials and methods: A cross-sectional study was carried out in 100 patients att...
متن کاملContrast-induced nephropathy.
Contrast-induced nephropathy is defined as a serum creatinine level that increases by at least 25% or is 44.2 μmol/L greater than baseline within three days of receiving contrast medium intravascularly in the ab sence of another cause. Contrastinduced nephropathy is usually selflimiting; at worst, it can make the patient permanently dependent on hemodialysis or can result in death. Main risk fa...
