A major endogenous ligand substance involved in renal failure
1Department of Internal Medicine and Nephrology, Nishijin Hospital, Kyoto, Japan.
Abstract:
The clinical significance of a major endogenous ligand substance, 3-carboxy-4-methyl-5-propyl-2-furanpropanoic acid (CMPF), present in the sera of patients with renal failure, was examined. In patients with chronic renal failure, the serum CMPF concentration was correlated with the serum creatinine concentration, but not in patients with acute renal failure. The accumulation of CMPF in the sera of patients with chronic renal failure may reflect the 'chronicity' of renal failure. Plasma exchange was more effective than direct hemoperfusion for the elimination of CMPF retained in uremic serum.

Glomerulus: Structure and Function
The glomerulus is a tiny, intricate network of capillaries located at the beginning of the nephron. It's enveloped by the Bowman's capsule and receives its blood supply from an afferent arteriole, which divides into numerous capillaries...
Dialysis
Acute kidney injury develops suddenly and can be caused by pre-renal causes (e.g., hypovolemia, shock), intrinsic renal causes (e.g., acute tubular necrosis), or post-renal causes (e.g., urinary obstruction). In contrast, chronic renal failure progresses gradually over time and is often...
Renal Drug Excretion: Tubular Secretion
Renal Failure: Dose Adjustments
Reduced renal clearance and elimination rate are common outcomes of renal impairment. These alterations lead to a prolonged elimination half-life and an altered apparent volume of distribution for drugs. As a result, dosage adjustments are typically necessary to maintain optimal drug levels in the body.
