Plasma beta-thromboglobulin levels in chronic renal failure patients. 1981

T Akizawa, and H Nishiyama, and S Koshikawa

Impaired platelet function is commonly recognized in uremia. It is partially improved by dialysis. However, in regular hemodialysis patients (RD), platelet function is not fully evaluated. This study investigated platelet activity in chronic renal failure (CRF) using beta-thromboglobulin (BTG) as a marker. BTG in RD were significantly higher than those in non-dialyzed CRF patients (P less than 0.05), and BTG in non-dialyzed CRF were higher than in normal controls (P less than 0.01). In non-dialyzed CRF, BTG were correlated to serum creatinine value (P less than 0.01). Arteriovenous fistula did not affect BTG. Hemodialysis and direct hemoperfusion with charcoal beads increased BTG but neither peritoneal dialysis nor hemofiltration altered BTG. RD treated over one year showed higher BTG than those treated for less than one year (P less than 0.01). In RD who showed elevated BTG, platelet aggregation and retention rates were depressed and bleeding times were prolonged. These results indicate that BTG can be used as the marker of impaired platelet function in CRF and of the blood compatibility of artificial kidneys.

UI	MeSH Term	Description	Entries
D007676	Kidney Failure, Chronic	The end-stage of CHRONIC RENAL INSUFFICIENCY. It is characterized by the severe irreversible kidney damage (as measured by the level of PROTEINURIA) and the reduction in GLOMERULAR FILTRATION RATE to less than 15 ml per min (Kidney Foundation: Kidney Disease Outcome Quality Initiative, 2002). These patients generally require HEMODIALYSIS or KIDNEY TRANSPLANTATION.

D010974	Platelet Aggregation	The attachment of PLATELETS to one another. This clumping together can be induced by a number of agents (e.g., THROMBIN; COLLAGEN) and is part of the mechanism leading to the formation of a THROMBUS.	Aggregation, Platelet
D006435	Renal Dialysis	Therapy for the insufficient cleansing of the BLOOD by the kidneys based on dialysis and including hemodialysis, PERITONEAL DIALYSIS, and HEMODIAFILTRATION.

D006464	Hemoperfusion	Removal of toxins or metabolites from the circulation by the passing of blood, within a suitable extracorporeal circuit, over semipermeable microcapsules containing adsorbents (e.g., activated charcoal) or enzymes, other enzyme preparations (e.g., gel-entrapped microsomes, membrane-free enzymes bound to artificial carriers), or other adsorbents (e.g., various resins, albumin-conjugated agarose).

D001609	Beta-Globulins	Serum proteins with an electrophoretic mobility that falls between ALPHA-GLOBULINS and GAMMA-GLOBULINS.	Beta(1)CA Globulin,Beta-Globulin,Beta Globulin,Beta Globulins
D001620	beta-Thromboglobulin	A platelet-specific protein which is released when platelets aggregate. Elevated plasma levels have been reported after deep venous thrombosis, pre-eclampsia, myocardial infarction with mural thrombosis, and myeloproliferative disorders. Measurement of beta-thromboglobulin in biological fluids by radioimmunoassay is used for the diagnosis and assessment of progress of thromboembolic disorders.	beta-2 Thromboglobulin,Thromboglobulin, beta-2,beta 2 Thromboglobulin,beta Thromboglobulin
