2015-06-01 · Macrocomplexes between immunoglobins and aspartate aminotransferase (macro-AST) may result in persistently increased AST concentration. The presence of macro-AST in patients has been implicated in unnecessary investigations of abnormal liver function tests. We report the case of a 44-year-old female who presented to the rheumatology clinic with a 12-months' history of constant widespread pain affecting her limbs and was found to have an elevated AST concentration. Persistent elevation of aspartate aminotransferase (AST) activity in serum due to the presence of a macroenzyme form of AST (macro-AST) may lead to diagnostic confusion in many clinical conditions, particularly those associated with chronic liver disease. 2012-06-01 · Presence of macro-aspartate-amino transferase (macro-AST) is generally detected in patients with chronic hepatitis, malignancies and autoimmune disease, but only seldom will it be detected in patients without evidence of clinical pathologies. 2017-11-01 · However, the diagnosis of macro-AST is usually delayed because of confusion about the reason for elevated AST activity, and many unnecessary medical tests and procedures are frequently performed, including invasive liver biopsies, before the final diagnosis is established. 1 No specific treatment is required for macro-AST.

AST is present in both cytoplasm and mitochondria of cells. In cases involving mild tissue injury, the predominant form of AST is that from the cytoplasm. Severe tissue damage results in more of the mitochondrial enzyme being released. Conclusion: Clinicians should consider testing for macro-AST when elevated AST is the only abnormal lab finding. Although an uncommon finding, macro-AST may be seen in both children and adults. There are many reasons for this phenomenon, including resolved acute hepatitis or in some cases, inflammatory bowel disease, hepatic Is there a way to generate an ast from the macros given their tokens?

Sowohl die mitochondriale (m-AST) als auch die zytosolische (c-AST) Form des Enzyms, welche die gleichen Reaktionen Alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase and bilirubin are biochemical markers of liver injury. Albumin, bilirubin, and prothrombin time are markers of hepatocellular function. This was an issue I found while working on #7970.

A diagnostic test, serum AST enzyme electrophoresis, was ordered. Macro-AST, accounting for nearly 100% of total serum AST, was evident on the enzyme electrophoresis carried out at Mayo Medical Laboratories. Introduction Macro aspartate aminotransferase (macro-AST) has rarely reported as benign cause for increased plasma AST activities (ASAT).
Macro-AST or isolated AST-elevation is not a com-mon feature in MCAD-deficiency.

We describe a case of chronic elevation of serum aspartate aminotransferase (AST) activity due to the presence of a macro-enzyme form of AST (macro-AST) in a young female followed up for 12 years. This biochemical abnormality, although generally detected in acute and chronic hepatitis, malignancies … 2012-10-01 In March 2000, the differential diagnosis of macro–aspartate transaminasemia (macro-AST) was considered for the first time. A diagnostic test, serum AST enzyme electrophoresis, was ordered. Macro-AST, accounting for nearly 100% of total serum AST, was evident on the enzyme electrophoresis carried out at Mayo Medical Laboratories.
