Lim, MD, FACG, FAASLD3 1Division of Gastroenterology/Hepatology, Department of Medicine, Stanford University School of Medicine, Palo Alto, California, USA; 2Digestive Health Institute, University Hospitals Cleveland Medical Center and Division of Gastroenterology and Liver Disease, Department of Medicine, Case Western Reserve University School of Medicine, Cleveland, Ohio, USA; 3Yale Viral Hepatitis Program, Yale University School of Medicine, New Haven, Connecticut, USA. Am J Gastroenterol 2017; 112:18–35; doi:10.1038/ajg.2016.517; published online 20 December 2016 Abstract Clinicians are required to assess abnormal liver chemistries on a daily basis. The most common liver chemistries ordered are serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase and bilirubin. These tests should be termed liver chemistries or liver tests. Hepatocellular injury is defined as disproportionate elevation of AST and ALT levels compared with alkaline phosphatase levels. Cholestatic injury is defined as disproportionate elevation of alkaline phosphatase level as compared with AST and ALT levels. The majority of bilirubin circulates as unconjugated bilirubin and an elevated conjugated bilirubin implies hepatocellular disease or cholestasis. Multiple studies have demonstrated that the presence of an elevated ALT has been associated with increased liver-related mortality. A true healthy normal ALT level ranges from 29 to 33 IU/l for males, 19 to 25 IU/l for females and levels above this should be assessed. The degree of elevation of ALT and or AST in the clinical setting helps guide the evaluation.

  • Genetically Determined Hypoalbuminemia As a Risk Factor for Hypertension: Instrumental Variable Analysis Jong Wook Choi1, Joon‑Sung Park2* & Chang Hwa Lee2*
    www.nature.com/scientificreports OPEN Genetically determined hypoalbuminemia as a risk factor for hypertension: instrumental variable analysis Jong Wook Choi1, Joon‑Sung Park2* & Chang Hwa Lee2* Hypoalbuminemia is associated with vascular endothelial dysfunction and the development of chronic cardiovascular diseases. However, the relationship between serum albumin concentration and blood pressure changes remains controversial. Community‑based longitudinal cohort data collected from Korean Genome and Epidemiology Study were used in this study. Hypoalbuminemia was defned as a serum albumin concentration of ≤ 4.0 g/dL. A total of 4325 participants were categorized into control (n = 3157) and hypoalbuminemia (n = 1168) groups. Serum albumin had a non‑linear relationship with the risk of hypertension development. A genome‑wide association study revealed 71 susceptibility loci associated with hypoalbuminemia. Among susceptibility loci, genetic variations at rs2894536 in LOC107986598 and rs10972486 in ATP8B5P were related to elevated blood pressure. Serum albumin (HR = 0.654, 95% CI 0.521–0.820) and polymorphisms of rs2894536 (HR = 1.176, 95% CI 1.015–1.361) and rs10972486 (HR = 1.152, 95% CI 1.009–1.316) were signifcant predictors of hypertension development. Increased albumin concentration instrumented by 2 hypoalbuminemia‑associated SNPs (rs2894536 and rs10972486) was associated with decreased HRs for hypertension development (HR = 0.762, 95% CI 0.659–0.882 and HR = 0.759, 95% CI 0.656–0.878). Our study demonstrated that genetically determined hypoalbuminemia is a signifcant predictor of incipient hypertension. Albumin, one of the major serum proteins, has multiple important physiological functions involving stabilization of plasma colloid osmotic pressure, transportation of diverse substances, and signifcant antioxidant activity, and its concentration is fnely regulated by various systems in the physiologic state 1.

  • Glycated Hemoglobin and Glycated Albumin in Patients with Diabetes
    Kitajima et al. Renal Replacement Therapy (2020) 6:10 https://doi.org/10.1186/s41100-020-0260-5 RESEARCH Open Access Glycated hemoglobin and glycated albumin in patients with diabetes undergoing hemodiafiltration Yukie Kitajima1*, Shunichiro Urabe2, Takashi Hosono2, Satoshi Yoshikawa3, Yuzuru Sato3 and Toru Hyodo2 Abstract Background: Online hemodiafiltration (OHDF), which results in high albumin leakage, is now widely used in Japan for dialysis, since the national insurance system began reimbursing its costs in 2012. Glycated albumin (GA) levels are affected by albumin leakage into effluent dialysate fluid. Therefore, GA levels in patients requiring diabetes- related dialysis undergoing OHDF require monitoring. However, there have been no previous reports on glycemic control indicators of patients with diabetes undergoing OHDF. We aimed to develop a glycemic control index for patients requiring diabetes-related dialysis undergoing OHDF. Methods: This study comprised 133 diabetic patients undergoing OHDF. We examined the correlation between GA and glycated hemoglobin (HbA1c) levels. We analyzed effluent dialysate fluid samples from 41 patients classified into 3 groups, namely, group A, non-protein-leaking OHDF (n = 20); group B, protein-leaking OHDF (n = 14); and group C, highly efficient protein-leaking OHDF (n = 7). We examined the association between GA and HbA1c levels in each group and among patients. Results: A significant positive correlation was observed between GA and HbA1c levels (r = 0.562, p < 0.0001). There was no significant correlation between pre-dialysis blood glucose levels and HbA1c or GA levels as observed on regular blood tests performed under non-fasting conditions. Patients were classified into 2 groups based on their mean albumin levels (3.4 g/dL cutoff).

  • Understanding Your Liver Function Results
    www.healthinfo.org.nz Understanding your liver function results Your liver is a very important organ that has many jobs. Some of its jobs are to make proteins, make bile to help you digest fats, store energy, and break down some toxins and medicines. Liver function tests are done if you have symptoms of a liver condition or risk factors for liver disease such as fatty liver, viral hepatitis or high alcohol use. They are also checked if you are taking medicines that can affect how your liver works. Terms used Protein: this is the total of all the different types of protein in your blood. Albumin: this is the main protein your liver makes. It goes into your blood and helps to carry many things around your body. Bilirubin: this is something your body makes when it breaks down old red blood cells and replaces them with new ones. Bilirubin gives bile its yellow colour. Alkaline phosphatase (ALP): this is an enzyme in your liver and bones. (An enzyme is a chemical that helps to speed up other chemical processes.) GGT: this stands for gamma glutamyltransferase, which is an enzyme in your liver. ALT: this stands for alanine aminotransferase, which is another enzyme in your liver. AST: this stands for aspartate aminotransferase, which is also an enzyme in your liver. Normal result If you have a copy of your test results, it will show your results and a normal range for each test. The normal ranges may vary depending on your gender and age group and whether you're pregnant or have any underlying health conditions.

  • The Asymptomatic Outpatient with Abnormal Liver Function Tests 169 Leading to Shortage of Pyridoxal 50-Phosphate, Which Is a Cofactor for Both AST and ALT
    The Asymptomatic Outpatient with Abnormal Liver FunctionTests Michael Krier, MD, Aijaz Ahmed, MD* KEYWORDS Aminotransferases (ALT and AST) LFT Alkaline phosphatase Albumin Prothrombin time Traditionally, the constellation of biochemistry tests including liver enzymes, total bili- rubin, and hepatic synthetic measures (prothrombin time (PT) and serum albumin level) are referred to as liver function tests (LFTs). Abnormal LFTs can be encountered during primary health care visits, routine blood donation, and insurance screening. A reported 1% to 4% of asymptomatic patients exhibit abnormal LFTs, leading to a size- able number of annual consultations to a gastroenterology and/or hepatology prac- tice.1 A cost-effective and systematic approach is essential to the interpretation of abnormal LFTs.2–7 A review of pattern of abnormal LFTs, detailed medical history, and a comprehensive physical examination help establish a foundation for further indi- vidualized testing. Further investigation often involves biochemical testing for disease- specific markers, radiographic imaging, and even consideration of a liver biopsy. In the following account, markers of hepatic injury are reviewed followed by a discussion on an approach to various patterns of abnormal LFTs in an asymptomatic patient. ABNORMAL LFTS: MARKERS OF HEPATIC INJURY Abnormal LFTs can be found in 2 main predominant patterns of hepatic injury, hepa- tocellular necrosis or cholestasis. Differentiation between these 2 main patterns of hepatic injury provides clues for further testing. However, in practice, patients present with a mixed pattern of hepatic injury. Markers of Hepatocellular Injury Aminotransferases Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) are normally intracellular enzymes with mitochondrial and cytoplasmic forms.8 Their names reflect Division of Gastroenterology and Hepatology, Stanford University School of Medicine, 750 Welch Road, Suite # 210, Stanford, CA 94304, USA * Corresponding author.

  • Elevated Transaminases and Hypoalbuminemia in Covid-19 Are Prognostic Factors for Disease Severity
    www.nature.com/scientificreports OPEN Elevated transaminases and hypoalbuminemia in Covid‑19 are prognostic factors for disease severity Jason Wagner1, Victor Garcia‑Rodriguez1, Abraham Yu1, Barbara Dutra1, Scott Larson1, Brooks Cash1, Andrew DuPont1 & Ahmad Farooq2,3* Prognostic markers are needed to understand the disease course and severity in patients with Covid‑ 19. There is evidence that Covid‑19 causes gastrointestinal symptoms and abnormalities in liver enzymes. We aimed to determine if hepatobiliary laboratory data could predict disease severity in patients with Covid‑19. In this retrospective, single institution, cohort study that analyzed patients admitted to a community academic hospital with the diagnosis of Covid‑19, we found that elevations of Aspartate Aminotransferase (AST), Alanine Aminotransferase (ALT) and Alkaline Phosphatase (AP) at any time during hospital admission increased the odds of ICU admission by 5.12 (95% CI: 1.55–16.89; p = 0.007), 4.71 (95% CI: 1.51–14.69; p = 0.01) and 4.12 (95% CI: 1.21–14.06, p = 0.02), respectively. Hypoalbuminemia found at the time of admission to the hospital was associated with increased mortality (p = 0.02), hypotension (p = 0.03), and need for vasopressors (p = 0.02), intubation (p = 0.01) and hemodialysis (p = 0.002). Additionally, there was evidence of liver injury: AST was signifcantly elevated above baseline in patients admitted to the ICU (54.2 ± 15.70 U/L) relative to those who were not (9.2 ± 4.89 U/L; p = 0.01). Taken together, this study found that hypoalbuminemia and abnormalities in hepatobiliary laboratory data may be prognostic factors for disease severity in patients admitted to the hospital with Covid‑19.
