Plasma and urinary prothrombin concentration and plasma prothrombin activity were measured in a group of 17 patients with the nephrotic syndrome. An immunologic assay using a monospecific antibody against human prothrombin was employed in the measurement of prothrombin concentration in the plasma and urine. Prothrombin-deficient plasma was used as the substrate in the measurement of plasma prothrombin activity. A control group consisting of five normal volunteers was included for comparison. Both the activity and concentration of prothrombin were significantly lower in the nephrotic group as compared with the control group. Significant quantities of immunoreactive prothrombin were detected in the urine of the majority of nephrotic patients. This study has provided unequivocal evidence of urinary excretion and acquired deficiency of prothrombin in the nephrotic syndrome.

UI MeSH Term Description Entries
D007020 Hypoprothrombinemias Absence or reduced levels of PROTHROMBIN in the blood. Factor II Deficiency,Prothrombin Deficiency,Deficiency, Factor II,Hypoprothrombinemia,Deficiencies, Factor II,Deficiencies, Prothrombin,Deficiency, Prothrombin,Factor II Deficiencies,Prothrombin Deficiencies
D007122 Immunoelectrophoresis A technique that combines protein electrophoresis and double immunodiffusion. In this procedure proteins are first separated by gel electrophoresis (usually agarose), then made visible by immunodiffusion of specific antibodies. A distinct elliptical precipitin arc results for each protein detectable by the antisera.
D008297 Male Males
D008875 Middle Aged An adult aged 45 - 64 years. Middle Age
D009404 Nephrotic Syndrome A condition characterized by severe PROTEINURIA, greater than 3.5 g/day in an average adult. The substantial loss of protein in the urine results in complications such as HYPOPROTEINEMIA; generalized EDEMA; HYPERTENSION; and HYPERLIPIDEMIAS. Diseases associated with nephrotic syndrome generally cause chronic kidney dysfunction.

D010314 Partial Thromboplastin Time The time required for the appearance of FIBRIN strands following the mixing of PLASMA with phospholipid platelet substitute (e.g., crude cephalins, soybean phosphatides). It is a test of the intrinsic pathway (factors VIII, IX, XI, and XII) and the common pathway (fibrinogen, prothrombin, factors V and X) of BLOOD COAGULATION. It is used as a screening test and to monitor HEPARIN therapy.

D011516 Prothrombin A plasma protein that is the inactive precursor of thrombin. It is converted to thrombin by a prothrombin activator complex consisting of factor Xa, factor V, phospholipid, and calcium ions. Deficiency of prothrombin leads to hypoprothrombinemia.
