What is interstitium of nephron?
The renal interstitium is defined as the intertubular, extraglomerular, extravascular space of the kidney. It is bounded on all sides by tubular and vascular basement membranes and is filled with cells, extracellular matrix, and interstitial fluid (1).
Which drugs causes nephrotoxicity?
Drugs Associated with Nephrotoxicity
| Drug class/drug(s) | Pathophysiologic mechanism of renal injury |
|---|---|
| Haloperidol (Haldol) | Rhabdomyolysis |
| Pamidronate (Aredia) | Glomerulonephritis |
| Phenytoin (Dilantin) | Acute interstitial nephritis |
| Quinine (Qualaquin) | Thrombotic microangiopathy |
What is renal interstitium made of?
The interstitium of the kidney comprises the extravascular intertubular spaces of the renal parenchyma, with their attendant cellular elements and extracellular substances. As we define it here, the interstitium is bounded on all sides by tubular and vascular basement membranes.
How do nephrotoxic drugs cause kidney damage?
High metabolic rates of TALH tubular cells increase risk for drug nephrotoxicity. Kidney metabolism of drugs to toxic metabolites and ROS overwhelms local antioxidants and promotes tubular injury. Increased concentrations of potentially nephrotoxic drugs in the medulla and interstitium increase kidney injury.
What is the interstitium organ?
What is the interstitium? Unlike a more solid, contained organ like the heart or the liver, the interstitium is a network of tissue that surrounds nearly every organ system in the body. Just as our skin hugs us on the outside, this tissue layer wraps around organs inside our bodies.
What is Pyonephrosis mean?
Pyonephrosis—pus in the renal pelvis—results from urinary tract obstruction in the presence of pyelonephritis. Purulent exudate (inflammatory cells, infectious organisms, and necrotic, sloughed urothelium) collects in the hydronephrotic collecting system (“pus under pressure”) and forms an abscess.
Which antibiotics are the most nephrotoxic?
The potentially nephrotoxic antibiotics in current clinical use are neomycin, kanamycin, paromomycin, bacitracin, the polymyxins (polymyxin B, and colistin), and amphotericin B.
What is cortical interstitium?
In all parenchymal organs, including the kidney, the interstitium is situated in the space between the basement membranes of the epithelial cells and of the nutritive capillaries (Fig. The fibroblasts in the interstitium provide the “skeleton” of the tissue and maintain the three-dimensional architecture of the tissue.
What is the most nephrotoxic antibiotic?
Why is furosemide nephrotoxic?
The accumulation of ions inside the lumen of renal tubules after administration of furosemide inhibits the passive re-absorption of potassium, calcium and magnesium, resulting in increased urinary losses of these ions.
Why is the interstitium important?
The interstitium likely acts as a kind of shock absorber for the rest of our interior bits and bobs and the workings of the fluid itself could help explain everything from tumor growth to how cells move within our bodies.
