Background: Introduction: Searching for an ideal marker for diagnosing neonatal infection is still an important concern in every country. There are many biomarkers reported for neonatal sepsis. Haptoglobin is an acute phase reactants which rise in response to infection and injuries. In this report we discussed the efficacy of serum haptoglobin level in different cut off levels in early onset ne...
OBJECTIVE The haptoglobin 2-2 genotype is associated with lower haptoglobin concentrations and atherosclerosis in diabetes. Endothelial cell apoptosis contributes significantly to atherosclerosis. We studied endothelial cell apoptosis in diabetes patients with haptoglobin 2-2 and non-haptoglobin 2-2 genotype. Approach and results: We pooled plasma from 10 patients with haptoglobin 2-2 and non-h...
BACKGROUND Hp(2) alleles of the haptoglobin alpha-chain polymorphism reduce the anti-oxidant properties and increase the pro-inflammatory actions of this acute-phase protein in a gene-dosage fashion. We hypothesized that the haptoglobin polymorphism might contribute to the increased oxidative stress and low-grade chronic inflammation frequently associated with polycystic ovary syndrome, obesity...
haptoglobin (hp) is a mammalian serum glycoprotein showing a genetic polymorphism with three types, 1-1, 2-2 and 1-2. hp appears to conserve the recycling of heme-iron by forming an essentially irreversible but non-covalent complex with hemoglobin which is released into the plasma by erythrocyte lysis. as an important consequence, haptoglobin-hemoglobin complex (hp-hb) shows considerable antiox...
Haptoglobin is a putative adiposity marker because its concentration in blood is increased in obese humans. The present studies examined haptoglobin release by explants of adipose tissue in primary culture. Haptoglobin was released by explants of human visceral and subcutaneous adipose tissue at a nearly linear rate over 48 h. Explants of visceral adipose tissue released more haptoglobin than d...
BACKGROUND Evidence is emerging that haptoglobin, an acute phase protein with immunomodulatory properties, is expressed by the endometrium of various species. The present study describes an in-depth investigation of haptoglobin expression and release in the rabbit reproductive tract and in preimplantation embryos. METHODS The full-length cDNA sequence of rabbit haptoglobin was determined by r...

Haptoglobin (Hp) is a haemoglobin-binding acute phase protein with three genetic types: Hp 1-1, Hp 2-1, Hp 2-2. We investigated 45 patients during the first 48 hours of acute myocardial infarction, and studied determinant factors and clinical correlates. Upon hospital admission, serum haptoglobin concentration was increased (1.95 +/- 0.94 g/l, mean +/- SD, P < 0.001) versus the reference popula...
Antibody to purified type 1-1 human serum haptoglobin was obtained in rabbits. Using this antiserum it was demonstrated that the antigenic determinants of the haptoglobin molecule reside in both alpha- and beta-chains. No immunological difference between the normal alpha(1F)- and alpha(1S)-chains of haptoglobin could be detected. A number of healthy individuals whose haptoglobin pattern appeare...
Haptoglobin is a major acute phase protein in bovines and reportedly increases in serum and milk whey during mastitis, highlighting its potential as a diagnostic biomarker. Since haptoglobin is known to undergo tissue specific glycosylation resulting in different isoforms, this study was undertaken to characterize the isoforms of haptoglobin. Milk whey fraction and serum obtained from animals w...
