AIMS To determine whether nontransferrin bound iron is present in the serum of long term survivors of acute leukaemia and bone marrow transplantation who have liver dysfunction as indicated by consistently raised serum aspartate aminotransferase (AST) activities. METHODS Thirty eight patients, who were at least three years from the end of treatment, were studied. Serum samples were analysed f...

BACKGROUND The presence of macroenzyme (M) is often the explanation of an isolated elevation of aspartate aminotransferase (AST). Where M is identified, it is reasonable for the clinician to ask where an individual patient's result fits in with known concentrations of M. In this context, we conducted a survey of literature to examine the distribution of reported serum concentrations of macro-AS...

Aspartate aminotransferase-to-platelet ratio (APRI), aspartate aminotransferase-to-alanine aminotransferase ratio (AAR), FIB-4, FI, King, Lok, Forns, and FibroIndex scores may be simple and convenient noninvasive diagnostic tests, because they are based on the regular laboratory tests and demographic data. This study aimed to systematically evaluate their diagnostic accuracy for the prediction ...

background: liver ischemic insults are important sources of liver injuries leading to production of reactive oxygen species (ros) and mediating liver cell injury. glutathione mediated mechanisms are among the most important defense mechanisms of the liver; n-acetylcysteine (nac) provides cysteine for glutathione defense mechanisms. patients undergoing cardiac surgery are at increased risk of li...

This work analyzes the prevalence of TTV DNA in peripheral blood cells from patients with hepatic alterations and healthy blood donors and measures levels of sodium, potassium, urea, creatinine, phosphatase alkaline, total and direct bilirubin, gamma glutamyl transferase (GGT), alanine aminotransferase (ALT) and aspartate aminotransferase (AST) in certain randomly selected patients. DNA samples...

OBJECTIVE To compare various biochemical markers i.e. APRI (AST to platelet ratio index), aspartate aminotransferase (AST) alanine aminotransferase (ALT) ratio, FIB-4 (AST, platelet, AST and age) with biopsy for assessing the severity of hepatic fibrosis in patients with hepatitis C. STUDY DESIGN Descriptive study. PLACE AND DURATION OF STUDY Medical Department, Liaquat University of Medica...

BACKGROUND The aim of this study was to evaluate whether the glutathione S-transferase M1 (GSTM1) and T1 (GSTT1) null alleles may contribute to carbamazepine-induced hepatotoxicity. METHODS A cross-sectional prospective study was conducted to identify the frequency distribution of GSTM1 and GSTT1 alleles in 129 Tunisian epileptic patients treated with carbamazepine. Null alleles were determin...

UNLABELLED Serum aminotransferase [such as aspartate aminotransferase (AST) and alanine aminotransferase (ALT)] is commonly used as an indicator of liver disease. The aim of the study was to determine the degree to which aminotransferase results are associated with increased mortality at the population level. All adult residents of Olmsted County, Minnesota, who had a health care encounter at M...

CONTEXT Paracetamol (acetaminophen or APAP) is the most common pharmaceutical exposure in the US. Elevations in aspartate aminotransferase (AST) and alanine aminotransferase (ALT) levels indicate hepatic toxicity. AST and ALT levels rise in similar proportions but later decline at different rates, with AST falling more rapidly than ALT. OBJECTIVE To determine whether the AST/ALT ratio can ind...

BACKGROUND Trace elements are required for the performance of numerous functions of immune cells. It is not clear whether levels of trace elements are elevated and whether there is a relationship between the levels of liver enzymes and trace elements in patients with sickle cell anaemia in crisis. OBJECTIVE To compare the plasma levels of liver enzymes and trace elements in non sickle cell an...
