170 Possible Causes for Aspartate Transaminase Increased

  • Chronic Alcoholism

    A 42-year-old man with a history of Billroth II-gastrectomy, chronic alcoholism, and malnutrition developed acute tetraparesis, two days before admission. He presented with bilateral, proximal upper and lower limb weakness, limb girdle wasting, bilaterally reduced Achilles tendon reflexes, and bilateral stocking-type[…][]

  • Myocardial Infarction

    The level of serum aspartate transaminase (AST) increases rapidly in 4 to 6 hours, reaches its peak in 24 to 48 hours, and returns to normal in five days.[] Enzymes such as glutamine oxaloacetic transaminase (aspartate aminotransferase) and lactate dehydrogenase are still being used for diagnosis of MI in some laboratories.[] Within 2 to 4 hours after infarction the level of creatine kinase (CK) is increased; it reaches its peak within 24 hours and subsides to normal level within 48 hours.[]

  • Liver Cirrhosis

    During liver injury, ALT released from damaged cells can rapidly increase ALT activity in the serum. 11 Aspartate transaminase (AST) is present not only in the liver but also[] Therefore, AST activity increases in the case of hepatic injury but is less specific for hepatic injury than ALT. 11, 12 The aim of this study was 2-fold.[]

  • Infectious Mononucleosis

    Novel commercial kits based on antibody reactivity to purified heterophile antigens have recently been introduced for the diagnosis of Epstein-Barr (EB) virus-associated infectious mononucleosis (IM). It is important to determine possible improvements in the performance and reliability of such tests for the diagnosis[…][]

  • Pulmonary Embolism

    BACKGROUND: Acute pulmonary embolism (APE) can be life-threatening. Early detection is even more difficult for patients under general anesthesia as common symptoms are not available and the pathophysiological course of intra-operative APE is influenced by procedures of surgery and anesthesia, which makes patients[…][]

  • Cholecystitis

    Song et al demonstrated that 424 of 1178 patients with ACC had increased liver tests (alanine transaminase (ALT), aspartate transaminase (AST) greater than twice normal levels[]

  • Viral Hepatitis

    Also, HBV DNA levels are increased. Additionally, alanine transaminase (ALT) and aspartate transaminase (AST) levels are consistently or intermittently elevated.[]

  • Liver Metastasis

    A solitary fibrous tumor seldom originates from the meninges, and the accuracy of imaging modalities in the diagnosis of meningeal SFT metastasisis is perlexing. Contrast enhanced imaging modalities, such as contrast enhanced ultrasound and contrast enhanced magnetic resonance imaging are valuable in the differential[…][]

  • Cholestasis

    The mechanisms of cholestasis can be broadly classified into hepatocellular, where an impairment of bile formation occurs, and obstructive, where impedance to bile flow occurs after it is formed. The typical histopathologic features of hepatocellular cholestasis include the presence of bile within hepatocytes and[…][]
