Biochemistry Lecture Notes - Uremia: Background, Pathophysiology, Etiology

Background
Uremia is a clinical syndrome associated with fluid, electrolyte, and hormone imbalances and metabolic abnormalities, which develop in parallel with deterioration of renal function. The term uremia, which literally means urine in the blood, was first used by Piorry to describe the clinical condition associated with renal failure.

Uremia more commonly develops with chronic kidney disease (CKD), especially the later stages, of CKD, but it also may occur with acute kidney injury (AKI) if loss of renal function is rapid. As yet, no single uremic toxin has been identified that accounts for all of the clinical manifestations of uremia. A number of toxins, such as parathyroid hormone (PTH), beta2 microglobulin, polyamines, advanced glycosylation end products, and other middle molecules, are thought to contribute to the clinical syndrome.

Blood Test Advances Diagnosis Of HELLP Syndrome

A laboratory blood test for the diagnosis of a rare genetic red blood cell disorder also shows promise in identifying HELLP syndrome, a life-threatening high blood pressure condition affecting 1% of all pregnant women.

HELLP is an acronym for hemolysis, elevated liver enzymes and low platelets and is a severe variant of pre-eclampsia whose pathogenesis remains unclear. Recent evidence and clinical similarities suggest a link to atypical hemolytic uremic syndrome, a disease of excessive activation of the alternative complement.
