Vaccines are considered to be one of the most human and veterinary medicine. Proteins which are expressed cost-effective life-saving interventions in human history. in the acute phase are potential biomarkers for the diagnosis The body's inflammatory response to vaccines has both of inflammatory disease, for example, acute phase proteins desired effects (immune response), undesired effects [(acute (APPs) are indicators of successful organ transplantation phase reactions (APRs)] and trade‑offs. Trade‑offs are and can be used to predict the ameliorative effect of cancer more potent immune responses which may be potentially therapy (1,2). APPs are primarily synthesized in hepatocytes. difficult to separate from potent acute phase reactions. The acute phase response is a spontaneous reaction triggered Thus, studying acute phase proteins (APPs) during vaccina- by disrupted homeostasis resulting from environmental distur- tion may aid our understanding of APRs and homeostatic bances (3). Acute phase reactions (APRs) usually stabilize changes which can result from inflammatory responses. quickly, after recovering from a disruption to homeostasis Depending on the severity of the response in humans, these within a few days to weeks; however, APPs expression levels reactions can be classified as major, moderate or minor. -
Influence of Infection and Inflammation on Biomarkers of Nutritional Status
A2.4 INFLUENCE OF INFECTION AND INFLAMMATION ON BIOMARKERS OF NUTRITIONAL STATUS A2.4 Influence of infection and inflammation on biomarkers of nutritional status with an emphasis on vitamin A and iron David I. Thurnham1 and George P. McCabe2 1 Northern Ireland Centre for Food and Health, University of Ulster, Coleraine, United Kingdom of Great Britain and Northern Ireland 2 Statistics Department, Purdue University, West Lafayette, Indiana, United States of America Corresponding author: David I. Thurnham; [email protected] Suggested citation: Thurnham DI, McCabe GP. Influence of infection and inflammation on biomarkers of nutritional status with an emphasis on vitamin A and iron. In: World Health Organization. Report: Priorities in the assessment of vitamin A and iron status in populations, Panama City, Panama, 15–17 September 2010. Geneva, World Health Organization, 2012. Abstract n Many plasma nutrients are influenced by infection or tissue damage. These effects may be passive and the result of changes in blood volume and capillary permeability. They may also be the direct effect of metabolic alterations that depress or increase the concentration of a nutrient or metabolite in the plasma. Where the nutrient or metabolite is a nutritional biomarker as in the case of plasma retinol, a depression in retinol concentrations will result in an overestimate of vitamin A deficiency. In contrast, where the biomarker is increased due to infection as in the case of plasma ferritin concentrations, inflammation will result in an underestimate of iron deficiency. Infection and tissue damage can be recognized by their clinical effects on the body but, unfortunately, subclinical infection or inflammation can only be recognized by measur- ing inflammation biomarkers in the blood. -

LEUKOCYTE SURFACE ORIGIN of HUMAN At-ACID GLYCOPROTEIN (OROSOMUCOID)*
LEUKOCYTE SURFACE ORIGIN OF HUMAN at-ACID GLYCOPROTEIN (OROSOMUCOID)* BY CARL G. GAHMBERG AND LEIF C. ANDERSSON (From the Department of Bacteriology and Immunology, and the Transplantation Laboratory, Department of Surgery IV, University of Helsinki, Helsinki 29, Finland) Human al-acid glycoprotein (orosomucoid) (o~I-AG)1 constitutes the main component of the seromucoid fraction of human plasma. It belongs to the acute phase proteins, which increase under conditions such as inflammation, pregnancy, and cancer (1, 2). al-AG has previously been found to be synthesized in liver (3), and after removal of terminal sialic acids, it is cleared from the circulation by binding to a receptor protein on liver cell plasma membranes (4). The structure of al-AG is well known. It is composed of a single polypeptide chain and contains 245% carbohydrate including a large amount of sialic acid. The carbohydrate is located in the first half of the peptide chain linked to asparagine residues (5, 6). The function of al-AG is unclear. However, Schmid et al. (5) and Ikenaka et al. (7) and reported that the amino acid sequence of the protein shows a significant homology with human IgG. This finding and the striking increase in inflammatory and lymphopro- liferative disorders made us consider the possibility that leukocytes could be directly involved in the synthesis and release of a~-AG. We report here the presence of a membrane form of al-AG, with an apparent tool wt of 52,000, on normal human lymphocytes, granulocytes, and monocytes. By the use of internal labeling with [3H]leucine in vitro, we demonstrate that the membrane protein is synthesized by lymphocytes. -

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). -
