The haptoglobin 2 allele was determined to be a risk factor for type 2 diabetes in Ghana (OR = 6.1, 95% CI = 1.8-21.2; P = .0.001) while the Hp1 allele appeared protective (OR = 0.56, 95% CI = 0.31-1.0; P = .06).
When combined with the glycation level of lysine-141 of haptoglobin, diagnostic accuracy improved further for newly diagnosed (SN, 94%; SP 96%) and long-term controlled (SN, 85%; SP, 94%) T2DM patients (HbA1c: SN, 88%; SP, 96%).
Haptoglobin(Hp) 2-2 genotype has been shown to increase coronary artery disease (CAD) risk in numerous type 2 diabetes studies but in only one type 1 diabetes cohort.
We investigated whether serum Hp has a causal effect on macroangiopathy via Mendelian randomization (MR) analysis with common variants of the Hp gene in Chinese patients with type 2 diabetes.
The genetic variant rs2000999 was not associated with diabetic macrovascular diseases but showed an association with metabolic traits and serum Hp levels in Chinese patients with type 2 diabetes.
To collectively evaluate the association between haptoglobin (Hp) gene variants and diabetic retinopathy (DR) in patients with type 2 diabetes mellitus (T2DM).
The Hp genotypes of 265 patients, 95 type 1 diabetes mellitus (DM1) sufferers with at least 10 years of disease and 170 type 2 diabetes mellitus (DM2) sufferers with at least 5 years of disease were determined by allele-specific PCR; both groups included patients with and without DN.
<b>Conclusions:</b> These results suggest that subjects with type 2 diabetes carrying the Hp 1-1 genotype may have higher susceptibility to depression in the context of white matter damage and frontal lobe atrophy.
Haptoglobin (Hp) polymorphisms have been suggested to be associated with many pathological conditions including cardiovascular diseases, infectious diseases, and type 2 diabetes.
The distribution of Hp2 allele was higher in T2DM subjects compared to nondiabetic controls and the HbA1c levels of T2DM subjects carrying at least one Hp2 allele tended to be higher than T2DM subjects with Hp 1-1.
We studied the association of the Hp gene polymorphism with T2DM in 584 unrelated T2DM patients and 690 control subjects with normal glucose tolerance among northern Chinese.
The Hp genotypes have been associated with microvascular and macrovascular complications in type 1 diabetes mellitus but the association in type 2 diabetes is more consistent with cardiovascular complications.
While only the RH and haptoglobin loci showed evidence of association with NIDDM, an admixture analysis of the combined allele frequency data revealed a pattern of decreasing NIDDM prevalence with increasing socioeconomic status (as approximated by neighborhood of residence) and a parallel decrease in Amerindian ancestry.
