Summary of "Yellowish discoloration of dialyzer."

A 43-year-old Chinese man with chronic viral hepatitis and end-stage renal disease, receiving conventional hemodialysis for 6 years, presented with general malaise and abdominal fullness. After 4.5 hours of hemodialysis, the hollow fibers of the dialyzer turned yellow. Biochemistry studies showed hyperbilirubinemia. The actual serum bilirubin (7.4 mg/dL) could be proved. Abdominal echography survey was negative. Hyperbilirubinemia was secondary to acute exacerbation of chronic viral hepatitis. Anuria and skin hyperpigmentation in uremia lack the tea-color urine and mask clinical jaundice in the presence of hyperbilirubinemia. Careful observation of dialyzer yellowish discoloration gave us timely discovery of patient's hyperbilirubinemia.

Medical and Biotech [MESH] Definitions

The yellowish discoloration of connective tissue due to deposition of HOMOGENTISIC ACID (a brown-black pigment). This is due to defects in the metabolism of PHENYLALANINE and TYROSINE. Ochronosis occurs in ALKAPTONURIA, but has also been associated with exposure to certain chemicals (e.g., PHENOL, trinitrophenol, BENZENE DERIVATIVES).

A condition that is caused by recurring atheroembolism in the lower extremities. It is characterized by cyanotic discoloration of the toes, usually the first, fourth, and fifth toes. Discoloration may extend to the lateral aspect of the foot. Despite the gangrene-like appearance, blue toes may respond to conservative therapy without amputation.

Coloration or discoloration of a part by a pigment.

Purplish or brownish red discoloration, easily visible through the epidermis, caused by hemorrhage into the tissues.
