Macro-AST in an asymptomatic young patient.
Elevated enzyme activities in plasma may sometimes be due to the presence of macroenzymes.1,2 Macroenzymes are high molecular mass complexes of plasma enzymes with immunoglobulins (IgG, IgA or IgM) or other plasma components with reduced plasma clearance and prolonged half life, resulting in elevated serum activities due to the “trapping” of the enzymes in serum.3 These results may thus be erro...
متن کاملMacro-AST: misleading finding in an adolescent with MCAD-deficiency
BACKGROUND MCAD-deficiency is the most common inborn error of fatty acid oxidation now included in many newborn screening programms using MS/MS. During prolonged catabolic episodes, patients may suffer from metabolic decompensation with dysfunction of liver, skeletal- and heart muscle as well as brain. In anabolism, neither clinical symptoms nor biochemical signs of organ dysfunction occur. C...
متن کاملPulmonary Valve Papillary Fibroelastoma in an Asymptomatic Young Patient
Cardiac papillary fibroelastoma (CPF) is an extremely rare primary cardiac neoplasm, only 8% of all primary cardiac tumors, but the most common neoplasm originating from the endocardium. The incidence of this pathology is estimated 0,019% in clinical series [1]. Most frequently CPF involves leftsided heart valves (89%), especially aortic valve (29%), whereas mitral valve is less interested (25%...
متن کاملAn asymptomatic nodule in an immunosuppressed patient.
45-year-old man with acute lymphocytic leukemia (ALL) was found to have a solitary pulmonary nodule on routine chest radiograph. He had been diagnosed as having ALL three months previously and underwent induction chemotherapy which included vincristine, prednisone, cyclophosphamide, doxorubicm and intrathecal methotrexate. His leukemia was in remission and he had received no chemotherapy for on...
متن کاملUnexplained High Activity of Aspartate Aminotransferase in an Asymptomatic Pediatric Patient
Elevated enzyme activities in plasma may at times be attributed to the presence of macro-enzymes. The macro-enzymes are often serum enzymes in complex with immunoglobulins, resulting in a greater molecular mass that cannot be filtered by renal glomeruli and are, hence, retained in the plasma. The aspartate aminotransferase (AST) can exist as a macro-enzyme, although it has been rarely reported....
