Objective: To evaluate the association between Haptoglobin (HP) gene polymorphisms with inflammatory status in obese subjects.
Materials And Methods: A cross-sectional study was carried out. A total of 276 apparently healthy men and nonpregnant obese women were enrolled and allocated according to the HP genotype into the HP (1)/HP (1), HP (2)/HP (1), and HP (2)/HP (2) groups. Distribution of HP genotypes was 49, 87, and 140 for the HP (1)/HP (1), HP (2)/HP (1), and HP (2)/HP (2), respectively. The HP genotype was determined using the polymerase chain reaction method. A multiple linear regression analysis adjusted by age, sex, waist circumference, and total body fat was used to determine the association between HP genotypes with TNF- α , IL-6, and high-sensitivity C-reactive protein (hsCRP) levels.
Results: A multiple linear regression analysis adjusted by sex, waist circumference, and total body fat was performed showing a significant association between the HP (2)/HP (2) genotype and TNF- α ( β = 0.180; 95% CI 14.41-159.64, P = 0.01) and IL-6 ( β = 0.188; 95% CI 1.53-12.72, P = 0.01) levels, but not with hsCRP ( β = -0.008; 95% CI -1.64-1.47, P = 0.914) levels, whereas the HP (2)/HP (1) genotype showed no association compared with the HP (1)/HP (1) genotype (control group).
Conclusion: Results of our study show that the HP (2)/HP (2) genotype is associated with elevated TNF- α and IL-6, but not with hsCRP, levels in obese subjects.

Introduction: Heart failure (HF) is a clinical syndrome characterized by cardinal symptoms that may be accompanied by signs. It results from structural and/or functional abnormalities of the heart leading to elevated intracardiac pressures and/or inadequate cardiac output at rest and/or during exercise. The prevalence of iron deficiency and anemia justifies the current guidelines recommendation of screening.

Background: Breast cancer is the leading cause of mortality among women, with over a million cases recorded globally. Haptoglobin (Hp) protein and genotypes play important roles in cancer predisposition and progression, but studies have reported varying outcomes in populations.
Aim: The association of Hp genotypes in breast cancer patients with malaria has not been investigated in Nigerians, which is the aim of our study.
Haptoglobin polymorphisms in Latin American populations.

Several genetic polymorphisms of the haptoglobin gene (HP) or haptoglobin-related gene (HPR) were reported to show a population-specific distribution and to be associated with not only serum haptoglobin (HP) but also cholesterol levels. For such association studies, it is important to know the distribution of polymorphisms or their haplotypes in the populations concerned. However, no comprehensive genetic studies have explored this in Latin Americans, and not every human variation or genotype is available in a database.

Cell-mediated immunity (CMI), IL-10, and the protective efficacy of modified-live porcine reproductive and respiratory syndrome virus (PRRSV) vaccines (MLV) against co-challenge with PRRSV-1 and PRRSV-2 (HP-PRRSV) were investigated. Seventy, PRRSV-free, 3-week old, pigs were allocated into 7 groups. Six groups were intramuscularly vaccinated with MLV, including Porcilis (PRRSV-1 MLV, MSD Animal Health, The Netherlands), Amervac (PRRSV-1 MLV, Laboratorios Hipra, Spain), Fostera (PRRSV-2 MLV, Zoetis, USA), Ingelvac PRRS MLV and Ingelvac PRRS ATP (PRRSV-2, Boehringer Ingelheim, USA), and Prime Pac PRRS (PRRSV-2 MLV, MSD Animal Health, The Netherlands).

Background: The serum haptoglobin (HP) level varies in various clinical conditions and among individuals. Recently, the common HP alleles, rs5472, and rs2000999 have been reported to associate with serum HP level, but no studies have been done on Africans. Here, we explored the relationship of not only these polymorphisms but also rs5470 and rs5471 to the serum HP level in 121 Ghanaians.
