Active clinical trials for "HIV Infections"

This is a prospective, 3-year observational study to describe drug utilization in uninfected individuals (UIs) who initiate emtricitabine (FTC)/tenofovir disoproxil fumarate (TDF) (Truvada®) for a pre-exposure prophylaxis (PrEP) indication. An electronic source of pharmacy/medical encounter information will be used to assess the demographics and other characteristics of the subjects prescribed FTC/TDF or its components in a prospective fashion. The data provider will supply all the de-identified information regarding each visit/interaction that the subject has had with the health system and all the diagnoses and medications that the UI has had prospectively and retrospectively for the length of time captured by the source selected. 200 physicians who prescribe FTC/TDF for a PrEP indication will be sampled from the same source.

The purpose of this study is to determine of once identified to the subjects infected with human immunodeficiency virus (positive VIH), to diagnose latent Tuberculosis, and to treat her with isoniazid for six months, measuring the production of Interferon range pre and posttreatment, to evaluate this way the result of the treatment on the immune response

A prospective cross-sectional study evaluates nutritional status and its relationship to the related factors in Thai HIV-infected patients who attending in out patient clinic.

This is an observational cohort in pediatric HIV patients in China. Children who receive antiretroviral drugs will be recruited in this study. The main objectives are as follows: 1. To establish simpler and smarter pediatric antiretroviral therapy in China including both first-line and second-line regimens. 2. To study the nature, characteristics and mechanisms of immunoreconstitution in HIV-infected children using the data and samples from the pediatric antiretroviral therapy cohort. 3. To establish a basic science and clinical research network based on the pediatric antiretroviral cohort.

HIV is increasing among adolescents and young adults in the US. Antiretroviral medications, when taken correctly (≥90% of prescribed doses taken), can vastly improve life expectancy. However, adherence among HIV-infected young people is suboptimal, and few interventions are available to help adolescents adhere to treatment. The first phase of the study is an intervention development phase, which includes conducting interviews with 40 HIV-infected youth for input on the adaptation of the approach. The information obtained from the qualitative interviews is used to adapt the Life-Steps intervention (designed by our group for HIV-infected adults) to be responsive to the needs of HIV-infected adolescents, with acceptability of topics and content, and feasibility of intervention delivery to be tested in an open pilot trial.

There has been an increase in incidence in sexually transmitted infections in HIV infected patients in the last years. In this study the investigators will prospectively evaluate the prevalence of symptomatic and asymptomatic infections with N. gonorrhea and Ch. trachomatis as well as the seroprevalence of Herpes simplex Type 2 infection in HIV-infected patients attending the clinic for infectious diseases at the Berne University Hospital. In addition, participants will be asked to fill out a questionnaire on sexual behaviour and sexual health. Study hypothesis: STI prevalence is high in certain risk-groups to justify screening in regular intervals.

We propose to conduct a multifactorial genetic study of cancer risk-related behaviors and other complex human characteristics. The main areas of interest are tobacco smoking, excess alcohol consumption, psychological traits, and HIV/AIDS susceptibility and progression. The subjects will be adult male and female probands who display one or more of the phenotypes of interest together with their brothers, sisters and parents. Information on tobacco and alcohol use, psychological and personality traits, sexual behavior, HIV status and progression, and other characteristics with possible genetic components will be obtained through structured interviews and questionnaires. DNA will be prepared from blood samples and typed for a series of candidate genes chosen for function and for random polymorphic markers. By correlating the genotypic and phenotypic information, we hope to identify individual loci that interactively contribute to many different aspects of human health and disease.

Virus present in semen likely contributes substantially to the sexual transmission of HIV. However, the source of HIV in semen is unknown. Some evidence suggests that the prostate may be the source of at least some of the virus in semen. This study is designed to determine whether the prostate may serve as the source of virus in semen by comparing the concentration of HIV-1 RNA in semen donated normally, in semen obtained following prostatic massage, and in expressed prostatic secretions. Finding a source for semen HIV would provide important insights into several aspects of HIV sexual transmission. Since some drugs do not enter the prostate well, the finding that virus is produced in the prostate might suggest the prostate could serve as a reservoir for HIV, leading to the development of resistance to antiviral agents.

The purpose of this study is to evaluate, in patients in at least the second protease inhibitor (PI) line, the virological failures under Kaletra® and their consequences on protease and reverse transcriptase genotypes

A total of 60 participants will be enrolled. They will be in 3 groups ARV-naïve, HIV-positive ≥ 20 year of age with HAD (n=25) who intend to start ARV ARV-naïve, HIV-positive ≥ 20 year of age without HAD (n=25), who intend to start ARV HIV-negative ≥ 20 year of age (n=10). The protocol team will work with the primary care physician to ensure that the subjects receive standard HIV and ARV care; however, initiation of ARV is not a requirement of the study and ARV will not be provided by the study. Participant accrual will include 10-15 participants per year. HIV-positive subjects will be tentatively enrolled in HAD vs. non-HAD groups by the enrolling neurologist and subsequently confirmed to that group by a consensus conference held every 6 months by the study neurologists. In cases of disagreement, cases will be re-assigned to the consensus conference determination and recruitment will continue. An external validation consensus conference will be conducted as well every 6-12 months to monitor correct assignment of the level of impairment.
