Lab Dept: Hematology Test Name: HAPTOGLOBIN General Information Lab Order Codes: HAPT Synonyms: N/A CPT Codes: 83010 – Haptoglobin; quantitative Test Includes: Total haptoglobin level reported in mg/dL. Logistics Test Indications: A decreased serum haptoglobin level is a very sensitive test of both intravascular and extravascular hemolysis, and reflects the rapid clearance by the reticuloendothelial system of a complex formed between liberated hemoglobin and circulatory haptoglobin. Low levels may also occur in hepatocellular disease, reflecting decreased synthesis by the liver, and that some patients may have a genetically determined deficiency of haptoglobin. Increased synthesis of haptoglobin in acute inflammatory states or malignancy may also mask depletion of serum haptoglobin due to hemolysis.

Its concentration correlates with disease activity in spondy- loarthropathies (SpAs). The Hp polymorphism determines the functional differences between Hp1 and Hp2 protein products. The role of the Hp polymorphism has been demonstrated in many diseases. In particular, the Hp 2-2 phenotype has been associated with the unfavorable course of some inflammatory and autoimmune disorders. Its potential role in modulating the immune system in SpA is still unknown. This article contains pathophysiological considerations on the potential relationship between Hp, its polymorphism and SpA.

However, the relationship seems complicated as both pro- and anti-inflammatory effects have been demonstrated. Methods/design: Twelve healthy volunteers (mean age 36, range 27–49 years) were treated in random order with increasing doses of GH for 3 weeks (first week 0.01 mg/kg per day, second week 0.02 mg/kg per day, and third week 0.03 mg/kg per day) or a GH receptor antagonist (pegvisomant; first week 10 mg/day and last two weeks 15 mg/day), separated by 8 weeks of washout. Circulating levels of the pro-inflammatory cytokines tumor necrosis factor a (TNFa (TNFA)), interleukin 6 (IL6), and IL1b (IL1B) and the acute phase proteins (APPs) C-reactive protein (CRP), haptoglobin, orosomucoid, YKL40 (CHI3L1), and fibrinogen were measured. Results: During GH treatment, IGF1 (median 131 (Inter-quartile range (IQR) 112–166) vs 390 (322– 524) mg/l, PZ0.002) increased together with TNFa (0.87 (0.74–1.48) vs 1.27 (0.80–1.69) ng/l, PZ0.003), IL6 (1.00 (0.83–1.55) vs 1.35 (0.80–4.28) ng/l, PZ0.045), and fibrinogen (9.2 (8.8–9.6) vs 11.1 (9.4–12.4) mM, PZ0.002).

Nossent¹ ¹Bone and Joint research group, Department of Health Science, Medical School, University of Tromsø, Norway ²Medical Genetics Department, University Hospital North Norway, Tromsø, Norway Abstract Objectives: B cell activating factor (BAFF) inhibitor therapy has recently been approved for non-renal Systemic Lupus Erythematosus (SLE). While BAFF plays a role in experimental lupus nephritis (LN), its role human LN is not well studied. Methods: Case control study in 102 SLE patients, 30 with LN (+LN) and 72 without LN (-LN) and 31 healthy controls. We analysed BAFF mRNA expression in PBMCs (BAFF-RQ) and serum BAFF (s-BAFF) levels and investigated their relation with clinical, histological- and additional acute phase proteins. Results: s-BAFF and BAFF-RQ were increased in +LN patients compared to controls, but their expression did not correlate with ISN/RPS class, Activity- or Chronicity index on biopsy. s-BAFF correlated with levels of anti-nucleosome antibodies, C1 inhibitor and α-1-acid-glycoprotein (AGP), while BAFF-RQ correlated inversely with Factor VIII.

Haptoglobin-Matrix Metalloproteinase 9 Complex As a Biomarker for Acute Inflammation in Cattle
Haptoglobin-Matrix Metalloproteinase 9 Complex as a Biomarker for Acute Inflammation in Cattle THESIS Presented in Partial Fulfillment of the Requirements for the Degree Master of Science in the Graduate School of The Ohio State University By Charles Austin Hinds D.V.M Graduate Program in Veterinary Clinical Sciences The Ohio State University 2011 Master's Examination Committee: Jeffrey Lakritz, Advisor Andrew Niehaus Christopher Premanandan Paivi Rajala-Schultz D. Michael Rings Copyrighted by Charles Austin Hinds 2011 Abstract Bovine respiratory disease (BRD) is a major cause of economic loss in feedlots in the United Sates. These losses are associated not only with morbidity and mortality, but also the expense of using antimicrobial drugs unnecessarily. One of the recurring problems is the inability to diagnose and therefore treat respiratory disease appropriately. An Hp-MMP 9 protein complex has been identified in neutrophil granules and in the serum of cattle with acute bacterial sepsis. The purpose of this project was to evaluate the utility of an Hp-MMP 9 complex ELISA in the diagnosis of acute septic inflammation in cattle. Three experiments were performed. The first experiment was designed to determine whether Hp-MMP 9 could be used in the prediction of BRD in calves recently admitted to feedlots. Using health, treatment and weight gain data, our aim was to determine whether Hp-MMP 9 could predict which calves would be identified with clinical respiratory disease and would require therapy in the days following sample collection. We compared serum concentrations of Hp to Hp-MMP 9 to assess how well the complex performed in these animals.

Chapter 4 HEMOSTASIS and BLOOD
Chapter 4 HEMOSTASIS AND BLOOD TRANSFUSION Tony Chang, MD, Elizabeth Donegan, MD The infusion of blood and blood products from one individual to another to stop or prevent bleeding, provide adequate oxygen delivery, and to prevent death from hemorrhage saves millions of lives. Nevertheless, the practice of Transfusion Medicine remains in its infancy. In the 20th century, blood transfusion became a relatively safe and common practice, despite the relative absence of transfusion guidelines based on randomized, prospective controlled trials. Most transfusion practices are based on convention and convenience. The understanding of hemostasis, safe transfusion practices, appropriate testing of blood and blood products, as well as the consequences of transfusion continues to unfold. An understanding of these principles is very important for anesthetists who transfuse about half of the blood transfused in hospitals. Without this knowledge, transfusion practices often result in poor outcomes. This chapter will discuss the current understanding of hemostasis, laboratory tests that assist in the decision of which components or products to transfuse and when to transfuse. Current pediatric transfusion practices, and the laboratory collection, preparation, and testing of blood and blood components are included. HEMOSTASIS Hemostasis is now understood to be a complex system of checks and balances designed to prevent abnormal clotting and uncontrolled bleeding. Coagulation is a cell-based event initiated on the surface of endothelial cells, in the subendothelium, and on platelets (Figure 4-1). 87 Chapter 4: HEMOSTASIS AND BLOOD TRANSFUSION Figure 4-1: Coagulation Overview of coagulation: Coagulation is activated when endothelium is disrupted and blood contacts tissue factor (TF). TF activates factor VII in turn activators factor X, which in combination with factor V, forms the prothombinase complex.

Arthritis Research & Therapy (2015) 17:45 DOI 10.1186/s13075-015-0553-1 RESEARCH ARTICLE Open Access Haptoglobin-α1, -α2, vitamin D-binding protein and apolipoprotein C-III as predictors of etanercept drug response in rheumatoid arthritis Sabine Blaschke1*, Kathinka Rinke1, Michael Maring1, Thomas Flad2, Susann Patschan1, Olaf Jahn3, Claudia A Mueller4, Gerhard A Mueller1 and Hassan Dihazi1 Abstract Introduction: The introduction of tumor necrosis factor-alpha (TNF-α) antagonists has substantially improved patient’s clinical outcome in rheumatoid arthritis (RA). However, nearly 20% to 40% of RA patients do not respond to anti-TNF-α treatment strategies. To identify valid predictors of TNF-α antagonist response in RA, serum proteome profiles from responders (R) and non-responders (NR) to etanercept, a soluble recombinant TNF-α receptor/IgG Fc fusion protein receptor, were compared in a prospective cohort study. Methods: In this clinical study 50 RA patients with inadequate response to conventional DMARDs were included and treated with etanercept. The primary efficacy endpoint was response according to the European League against Rheumatism (EULAR) improvement criteria. Serum samples collected prior to initiation and after six months of etanercept therapy were cleared of the most abundant major proteins by immunoaffinity chromatography. After separation by two-dimensional differential gel electrophoresis (2D-DIGE) and identification by mass spectrometry (MS) data were validated by Western blot analysis. Results: After six months of etanercept treatment 62% (n = 31) of RA patients achieved response. Haptoglobin-α1 (Hp-α1) and -α2 (Hp-α2) and vitamin D-binding protein (VDBP) were found to be significantly upregulated in responder sera (P ≤0.02) at study entry.
