Filter by: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.
The purpose of this study is to test a mother-to-mother intervention during pregnancy and after delivery with Mothers Living with HIV (MLH)in South Africa. We hypothesize that the intervention will enhance the adjustment of the children of MLH by improving the health and mental health of MLH which benefits their children, as well as the MLH.
This is a research study to determine if a personal health record, called myHERO, will help improve health. A personal health record is a secure internet (also called online) tool that contains personal health information like medications, diagnosed conditions, allergies and laboratory values (like CD4 cells and viral load). This study will also help explain if a personal health record influences the relationship with a doctor or nurse practitioner and their patients. The purpose of this study is to determine if a personal health record will influence health. The content of your personal health record is as secure as possible for any online health information.
Background: Novel HIV prevention approaches are urgently needed in Botswana and elsewhere in sub-Saharan Africa. Although adult male circumcision (MC) has been shown to reduce the heterosexual acquisition of HIV by men by about 60%, MC in infancy is optimal for its relative ease, lower cost and low rate of complications. We have conducted focus groups and semi-structured interviews that suggest neonatal MC (< 28 days of life) would be an acceptable public HIV prevention strategy in Botswana. The government of Botswana is committed to scaling up MC services in the immediate future and they plan to include neonates. Understanding decision-making around infant MC will be essential to maximize the effectiveness of this HIV prevention strategy. Specific Aims: The investigators propose to: 1) determine the acceptability and actual uptake of neonatal MC in southeastern Botswana and identify barriers to uptake; 2) ascertain the feasibility and safety of neonatal MC in Botswana; 3) Estimate what, if any, advantages would exist for scale up of Mogen Clamp, Plastibell or AccuCirc with regard to human resources, equipment needs, adverse events and acceptability to health-care providers and families in Botswana. Study Design and Schema: The investigators will conduct structured interviews with early postpartum mothers and fathers to determine correlates of neonatal MC acceptability and uptake, defined as neonatal MC following informed consent. Male infants will be circumcised by a trained doctor in a hospital / clinic setting by one of three FDA-approved devices that are currently in use in US hospitals: Mogen clamp, Plastibell or AccuCirc. Circumcision with Mogen Clamp or Plastibell will be done before 29 days of life. Circumcision with AccuCirc will be done before 11 days of life (FDA approval limit for device). The investigators will also administer questionnaires to the parents at the regular pediatric follow-up visit(s) to assess impressions of / satisfaction with the infant's procedure outcome over time. Provider impressions of the three methods will also be evaluated. Sample size will be 150 infants per arm for a total of 450 infants males circumcised (and an estimated 800 parental questionnaires). Public Health Significance: The World Health Organization (WHO) and UNAIDS state that countries with severe, generalized HIV epidemics but low rates of MC should offer this surgery as an important, evidence-based HIV prevention intervention, including among neonates. These two agencies also recommended that additional research on the most feasible, safe, and sustainable ways of scaling up MC intervention should be performed. This study will be in keeping with these recommendations. Please note the Mogen clamp and Plastibell study arms began as a randomized trial before the initiation of the AccuCirc single-arm portion. Although the settings in which the three devices were studied were similar, the AccuCirc trial enrollment began at two sites (Gaborone and Molepolole) only after completion of the Mogen clamp and Plastibell arms, which was conducted in three sites (Gaborone, Molepolole and Mochudi). Although Lobatse was a site for the first acceptability study with mothers, no procedures were performed there. Regarding the reported sample size: the total, final sample size includes both parents of newborn boys (because enrolled consenting parents completed questionnaires as part of this study), and boys whose parents consented to circumcision. We anticipated that not all parents who completed the questionnaire would consent to circumcising their baby; therefore, when planning the study it was necessary to estimate the number of parents who would participate in the survey (700), to achieve an enrollment of 300 neonates (therefore the initial estimate of 1000). The original study in fact enrolled 302 infants, 600 mothers and 19 fathers (total study population 921). The addition of the AccuCirc arm led to a revised estimate of total number of neonates and their parents (total=1250). The final enrollment was of 1,235 participants, that includes all the participating neonates and parents.
This study will evaluate the safety and acceptability of an intermittent and daily PrEP regimen using Tenofovir Disoproxil Fumarate plus Emtricitabine (FTC/TDF) in men and women at risk for HIV, and it will directly compare adherence and intracellular drug levels in daily and intermittent PrEP recipients. It will also evaluate the relationship between drug adherence, sexual behavior and intracellular drug levels with an intermittent PrEP regimen. In addition it will evaluate the relationship between adherence to an intermittent PrEP regimen and timing of sexual activity in relation to PrEP dosing. The study will use objective medication event monitoring medication event monitors (MEMS) adherence measurement and evaluate the feasibility of newer adherence measurements such as hair sampling and plasma drug levels. The study will also evaluate the feasibility of using SMS (text messages) to collect sexual activity data in an African setting. It will allow study teams and communities to prepare for potential subsequent larger trials of intermittent PrEP. This study is not sized to evaluate efficacy. If the intermittent PrEP regimen is shown to be safe, feasible in terms of adherence, and achieves intracellular drug levels similar to daily PrEP, these data could be used to design a larger phase 2 study with one or more intermittent PrEP regimens. The goal of such a trial would be to provide bridging data if daily PrEP regimens are found to be effective or to prepare for efficacy or non-inferiority trials of intermittent versus daily PrEP. Investigation of immune responses associated with FTC/TDF will also be evaluated in the pilot study. The proportion of volunteers on FTC/TDF with HIV-specific immune responses, due to exposures that did not lead to established HIV infection, will be assessed at 2-3 time points and compared to responses in volunteers assigned to placebo. Immune responses may be correlated with risk behavior and host factors, such as human leukocyte antigen (HLA) type. As noted above, very few HIV infections are expected to occur during the study, so correlation of HIV-specific immune responses and protection from infection or attenuation of disease progression will not be possible until a larger study is conducted.
The purpose of this study is to evaluate the efficacy of cotrimoxazole prophylaxis in prevention of malaria during pregnancy in HIV-infected women, compared to intermittent preventive treatment with mefloquine.
This phase II trial studies the immune response after stem cell transplant in human immunodeficiency virus (HIV)-positive patients with hematologic cancer (blood cancer). Studying samples of blood from HIV-positive patients with cancer in the laboratory may help doctors learn more about changes that occur in the immune system after stem cell transplant.
The purpose of this study is to develop an empirically validated, scientifically-based HIV and STI prevention program that can be delivered online to young men who have sex with men (YMSM) who were recently tested for HIV.
To evaluate the antiretroviral activity and safety of 200 mg BID and 300 mg BID doses of MPC-4326 administered as monotherapy for 14 days to HIV-1 positive patients. Patients with an initial treatment response will have the option to continue MPC-4326 in combination with an Optimized Backround Regimen for a maximum of 72 weeks.
Patients with HIV-1 infection on HAART regimen including 2 NRTI/NtRTIs plus one of the following : 1 PI/ritonavir or ATV/unboosted or 1 NNRTI, will be randomized to switch from the NNRTI/PI to maraviroc (300 mg /12 h) or to continue with the same approach.
