Background: Haptoglobin polymorphism is associated with the prevalence of infections, autoimmune diseases, cardiovascular diseases, and other disorders. Congenital haptoglobin deficiency is associated with anaphylactic transfusion reactions in anhaptoglobinaemic patients with antihaptoglobin antibody. Aims: To investigate haptoglobin genotypic distribution (including the Hp allele) and associat...
The haptoglobin 2-2 genotype is associated with atherosclerosis in type 2 diabetes mellitus. We examined the associations of the haptoglobin 2-2 genotype with C-reactive protein (high-sensitivity C-reactive protein) and carotid artery intima-media thickness, adjusting for age, gender, ethnicity, type 2 diabetes mellitus, smoking status, body mass index, blood pressure, glycated haemoglobin, non...
The overall survival time of non-small cell lung cancer (NSCLC) has not improved dramatically in recent decades. An important reason is the lacking of valuable biomarkers. Haptoglobin was reported to have activities of anti-inflammatory, anti-oxidant, autoimmune and tumor angiogenesis. However its potential role as a tumor biomarker was not well recognized. We used an immunoturbidimetry method ...
The interaction between human hemoglobin and haptoglobin has been followed by measuring the quenching of haptoglobin fluorescence associated with complex formation. The effects of varying the concentration of the reactants suggest that hemoglobin tetramers do not react with haptoglobin, but that hemoglobin subunits are involved. Separated a! chains of hemoglobin react with haptoglobin; although...
Haptoglobin is an acute phase protein showing a genetic polymorphism with 3 major types: Hp 1-1, Hp 2-1, and Hp 2-2. In this study, flow cytometric analysis demonstrated that all three haptoglobin types bind to CD22 on human B-lymphocytes with equal affinity. Comparison of reference values for lymphocyte subsets in peripheral blood and bone marrow showed significant differences between haptoglo...
The results indicate that haptoglobin may account for at least part of the inhibitor activity of plasma or serum. This seems to be consistent with the finding that administration of glucocorticoids in rats induced parallel changes in plasma inhibitor activity and haptoglobin concentration. However, no clear relationship between the haptoglobin concentration and the inhibitory actions of several...

Haptoglobin, the product of the Hp gene, is a glycoprotein involved in the scavenging of free hemoglobin. Haptoglobin levels increase or decrease in response to various acquired conditions, and they are also influenced by genetic predisposition. There were 2 major alleles, Hp (1) and Hp (2), and 1 minor allele, Hp (del) . Many researchers have attempted to study the haptoglobin types and their ...
preterm birth means the birth before thirty seven week of pregnancy that causes a lot of complications for the baby. variety factors are suggested to be involved in disease. in this study, we decided to evaluate haptoglobin (hp) phenotypes association with clinical features of patients suffered from premature delivery to understand better the possible correlation of genetic and clinical feature...
A specific, accurate and simple determination of haptoglobin is described with an antiserum against the antigenic determinants of the three haptoglobin phenotypes 1-1, 2-1 and 2-2. Antihaptoglobin is the determining factor in the formation of an antigen-antibody complex with maximal light absorption properties. Haptoglobin concentration is expressed as hemoglobin binding capacity. For the three...
