Background & Objective: Interleukin (IL)-10 is an important anti-inflammatory and immunomodulatory cytokine. Some authors believe that single nucleotide polymorphisms (SNP) in the promoter region of the IL-10 gene have been associated with susceptibility to HIV infection and progression to AIDS, but its role is not clearly defined yet. The present study was undertaken to evaluate the association between HIV infection susceptibility and progression with SNP in the promoter region of the IL-10 gene. Methods: This study was carried out on 70 HIV infected patients (39 treatment naïve and 31 undertreatment) and 31 matched healthy controls. The biallelic polymorphisms in the IL-10 gene promoter (-592 ,-1082) were analyzed by polymerase chain reaction and direct sequencing. Results: At position -1082, G/A was the most common genotype and A was the most prevalent allele and at position -592, A/C was the most prevalent genotype and -592 C was the most common allele in HIV positive patients; although there was not any significant difference between cases and controls regarding genotypes and alleles of these regions. Conclusion: Genetic polymorphisms of IL-10 promoter region may not associate with HIV infection outcome and the lack of this association suggests that other genes may influence on HIV infection course.

Background and Objectives: Human T-cell lymphotropic viruses (HTLV) type 1 and 2 are retroviruses that share the same routes of transmission as human immunodeficiency virus (HIV). As a consequence of epidemiologic similarities, HIV and HTLV-1/2 co-infection is frequent. Due to the limited data, this study assessed the seroprevalence of HTLV-1/2 infections in HIV infected patients in Tehran, Iran.
Materials and Methods: This case-control study was carried out in 180 HIV infected patients from Iranian HIV/AIDS Research Center in Tehran and 117 matched healthy controls. The serum samples were checked with enzyme-linked immunosorbent assay (ELISA) for anti HTLV-1/2.
Results: A total of 180 HIV positive patients with mean age 36.9±9.2 years and 117 matched controls were enrolled in the study. All cases and controls were negative for HTLV-1/2 infection.
Conclusion: HTLV-1/2 infection is negligible in HIV infected patients in Tehran, Iran, although intravenous drug use is the most common route of HIV transmission in our study subjects.
