“…It has been known that the SDF1 - 3 ′ A mutation could result in increased SDF1 production, resulting in delayed infection due to the strong competition with the CXCR-4 chemokine receptor. Other groups, however, did not observe a similar inhibitory effect, but instead reported that patients who were homozygous for the SDF1 - 3 ′ A variant had more-rapid disease progression [28-31]. Importantly, the frequency of the SDF1 - 3 ′ A mutation varies in different ethnic populations [32].…”

BackgroundGenetic variants of the genes encoding Human Immunodeficiency Virus-1 (HIV-1) co-receptors and their ligands, like CC-Chemokine Receptor 5 delta 32 mutation (CCR5-Delta32), CCR5 promoter A/G (Adenine/Guanine), CC-Chemokine Receptor 2 mutation 64 isoleucine (CCR2-64I) and the Stromal cell-derived Factor 3’A mutation (SDF1-3’A), are involved in the susceptibility to HIV-1 infection and progression. The prevalence of these mutations varies by Region. However, little is known about their distribution in the population of Dschang, located in the West Region of Cameroon. The prevalence of HIV in the West Region of Cameroon is lower than elsewhere in Cameroon. The objectives of this study were to determine the distribution of four AIDS Related Gene (ARG) variants in HIV-infected and non-infected population of Cameroon especially in the West Region and to estimate the contribution of these variants to the susceptibility or resistance to HIV infection. We also aimed to evaluate the effectiveness of genotyping using dried blood spot (DBS) samples.MethodsA total of 179 participants were recruited from two hospitals in Dschang in the West Region of Cameroon. Their genotypes for CCR5-Delta32, CCR5 promoter 59029A/G, CCR2-64I and SDF1-3’A were analyzed using polymerase chain reaction (PCR) and restriction fragment length polymorphisms.ResultsA total of 179 participants were enrolled in the study. Among them, 32 (17.9%) were HIV positive and 147 (82.1%) were HIV negative. The allelic frequencies of these genes were: 0%, 49.72%, 17.6% and 100% respectively for CCR5-Delta32, CCR5 promoter 59029A/G, CCR2-64I and SDF1-3’A. No individual was found to carry the CCR5-Delta 32 mutation. All participants recruited were heterozygous for the SDF1-3’A allele.ConclusionOur data suggest that the CCR5-Delta32 cannot account for the protection as it was completely absent in our population. SDF1-3’A variants, may be in association with other polymorphisms, may account for the overall protection from HIV-1 infection in participants recruited as everyone carries this allele. The CCR5 promoter 59029 G/G genotype may be associated with the risk for HIV-1 infection in this population, while the CCR2-64I (A/A genotype) may account for the protection against HIV infection. The results of genotyping from fresh blood and DBS were comparable.

Worldwide, more than one million children are infected with human immunodeficiency virus (HIV) and in the United States it has become the sixth leading cause of death among 15-24-year-olds. Despite the trend of increasing rates of infection, advances in therapies have led to survival past 5 years of age for more than 65% of infected children. This global health threat will therefore continue to have a significant impact on child and adolescent psychiatry and psychology. This paper reviews current studies and reports on the consequences of the acquired immunodeficiency syndrome (AIDS) epidemic in the psychiatric care and development of children and adolescents infected by HIV. From a search of all the English-language-based literature on pediatric AIDS, 140 studies are reviewed which address HIV infection and its psychological and social implications. Several topics of mental health significance are examined: (1) the epidemiology of HIV, (2) neurocognitive development among those infected, (3) psychological impact of infection, and (4) the family and social context of HIV. The transition of HIV from an acute, lethal disease to a subacute, chronic disease has enormous implications for the neurocognitive and psychosocial development of children and families. As children and adolescents infected with HIV continue to live longer, normal developmental milestones and educational needs will take on new significance. Many children will continue to be adversely impacted by non-HIV factors such as poverty, inadequate medical services, and a lack of social support. This review outlines recent developments that hold promise to effectively reduce the treatment burden on the infected, their families, and health care providers and to decrease the incidence of transmission to the uninfected.
