Anti-human immunodeficiency virus-1 antibody titers in injection drug users compared to sexually infected individuals.

چکیده
Sera from infected injection drug users (IDU) have shown to have antibodies against synthetic human immunodeficiency virus-1 (HIV-1) envelope peptides more frequently. In this study, reactivity of 48 IDU plasma were compared to 60 plasmas obtained from sexually infected individuals (S). The overall reactivity of plasma from IDU compared to S was higher, and the reactivity titers were much higher for IDU plasma than S. IDU plasma also showed a broader antibody response. The higher reactivity titers were observed mainly for the gp41 immunodominant epitope and V3 peptides corresponding to the consensus sequences of HIV-1 subtypes/variants prevalent in Brazil (B, F, C) indicating the specificity in the higher immune response of IDU.

Prevalence of Human Immunodeficiency Virus Infection among Injection Drug Users Released from Jail
Background: Injecting drug users (IDUs) and prisoners are considered to be highly vulnerable to human immunodeficiency virus (HIV) infection in Iran. This study was carried out to determine the prevalence of HIV infection among IDUs released from jail in Bahar (Hamadan, Iran). Methods: In a cross-sectional study, 118 IDUs who were prisoners during 2001-07 were evaluated. Their demographic and p...

Objective Dot Blot (DB) assay provides highly specific results, but usually not reliable for quantification of antibody production. The need for a more objective DB assay to provide a better definition of the immune status, against HIV antigens, promoted this study to be done to develop a quantitative DB assay. Material and Methods Dot blot (DB) strips for antibodies directed to human immuno...

Introduction: Human T-cell lymphotropic virus (HTLV), is a member of the retroviridae family. Infection with this virus leads to adult T-cell leukemia (ATL) and tropical spastic paraparesis (TSP). HTLV is endemic in Japan, parts of central Africa, Caribbean basin and Iran (Mashhad). Transmission routes of HTLV are believed to be from mother to child, especially during breastfeeding, sexual con...
متن کاملTetanus and Diphtheria Seroprevalence in Patients Infected With Human Immunodeficiency Virus
Background and Objectives: HIV infected patients are at risk for vaccine-preventable infections such as tetanus and diphtheria (Td). In these patients, these antibodies tend to decline faster. Due to the limited data, this study assessed the seroprevalence of tetanus and diphtheria antibodies in HIV infected patients in Tehran, Iran. Materials and Methods: This case-control study was carried o...
متن کاملImmune Response to Standard Hepatitis B Vaccination in HIV-Infected Patients
Background: Due to their similar routes of transmission, human immunodeficiency virus (HIV) and hepatitis B virus (HBV) co-infection occurs considerably. HBV infection progresses more rapidly in HIV-infected patients. Therefore, HBV vaccination of all non-immune HIV infected patients is recommended. On the other hand, HIV-infected subjects have suboptimal responses to HBV vaccine. In this study...
