We investigated human genetic variations in MBL2 in a Zimbabwean pediatric population and their putative associations with HIV infection in perinatally exposed children.
Neither the CCR2b-+/64I allele nor the SDF1-+/3'A allele, separately or in combination, had a significant impact on survival during the asymptomatic period of HIV infection.
Because IFN-gamma enhances IgG2 production, and IgG2 antibodies to HIV antigens and the 'high-affinity' polymorphism of FcgammaRIIa (the major Fc receptor for IgG2) have been associated with a favourable outcome of HIV infection, we examined the association of IgG2 antibodies to HIV p24 and 'high-affinity' polymorphisms of FcgammaRIIa with control of HIV replication in these patients.
We have analysed the association of mbl-2 structural and promoter polymorphisms with HIV infection and tuberculosis (TBC) in a white Spanish population, including 615 HIV patients with and without TBC, 127 no-HIV TBC patients, 142 TBC household contacts and 344 controls.
Synergy between mannose-binding lectin gene polymorphisms and supplementation with vitamin A influences susceptibility to HIV infection in infants born to HIV-positive mothers.
Role of the interleukin 10 family of cytokines in patients with immune reconstitution inflammatory syndrome associated with HIV infection and tuberculosis.
Our findings indicate significant association of pro-inflammatory (IL2, IFN-γ, TNF-α) and anti-inflammatory cytokine gene variants (IL4, IL10) with the risk to acquire the HIV infection and development of AIDS related illness in Indian population.
We have analysed the association of mbl-2 structural and promoter polymorphisms with HIV infection and tuberculosis (TBC) in a white Spanish population, including 615 HIV patients with and without TBC, 127 no-HIV TBC patients, 142 TBC household contacts and 344 controls.
After adjusting by age, route of HIV infection, length of infection before cART and viral hepatitis coinfection, CCR2 rs1799864-AG genotype was significantly associated with INR status (OR [95% CI]: 1.80 [1.04-3.11]; p = 0.04), and CXCL12rs1801157-TT genotype showed a trend (OR [95% CI]: 2.47 [0.96-6.35]; p = 0.06).
In this study, we examined the impact of the rs9264942 single-nucleotide polymorphism, previously shown to be associated with human immunodeficiency virus infection status and HLA-C expression, on the hepatitis C virus status in 359 people who inject drugs (PWID).
Associations of CCR5, CCR2, and stromal cell-derived factor 1 genotypes with human immunodeficiency virus disease progression in patients receiving nucleoside therapy.
The group of patients with liver cirrhosis shows a lower CD4+ T cell count at the inclusion in the study (but not at diagnosis of HIV infection), a higher percentage of individuals with previous alcohol abuse, and a higher proportion of patients with the genotype GG at position -238 of the TNF-α promotor gene; polymorphism at -592 of the IL-10 promotor gene approaches to statistical significance.
Associations of CCR5, CCR2, and stromal cell-derived factor 1 genotypes with human immunodeficiency virus disease progression in patients receiving nucleoside therapy.
Our findings suggest that mucosa-biased gradients of IP-10, macrophage inflammatory protein-1β, IL-8, and monocyte chemotactic protein-1 are associated with an increased risk of HIV infection.
The study aimed at assessing the existence and magnitude of genetic mutations of chemokine receptors, such as CCR2-64I, CCR-5 D-32, and SDF-1-3'A, that are known to confer resistance to HIV infection and progression of disease in some set-ups.
Two polymorphisms affecting HLA-C surface expression (rs9264942 and rs67384697) have recently been identified, and shown to influence progression of HIV infection.
We have investigated the prevalence of HLA-C alleles, in the specific clinical context of HIV infection complicated by type 1 psoriasis, in a case control study of 14 men with HIV disease and type 1 psoriasis and 147 HIV-infected patients without psoriasis.
The various epistatic effects observed here for common, distinct KIR3DL1 and HLA-B Bw4 combinations are unprecedented with regard to any pair of genetic loci in human disease, and indicate that NK cells may have a critical role in the natural history of HIV infection.
