Drug therapy for persons living with human immunodeficiency virus (HIV) or acquired immunodeficiency syndrome (AIDS) co-infected with latent tuberculosis infection (LTBI) is complex. Anti-tuberculosis drugs used to treat LTBI often induce drug metabolizing enzymes that share the same metabolic pathway as antiretroviral drugs used for those living with HIV/AIDS. This study evaluates the drug-drug interaction (DDI) potential of an antiretroviral drug when co-administered with a common anti-tuberculosis regimen of drugs.
Though HAV is mainly transmitted through the fecal-oral route, infection by sexual intercourse and blood transfusion is also possible. Injection drug users (IDUs) and men who have sex with men (MSM) have a higher risk of acquiring HAV due to their behaviors. Reemerging threat of hepatitis A among MSM in Taiwan has been reported recently. Based on the guidelines for the diagnosis and treatment of HIV/AIDS and the Advisory Committee on Immunization Practices (ACIP), Taiwan, vaccination of individuals against HAV with any of the following indications is recommended: HIV patients, adults with chronic hepatic disease, hemophilia, liver transplantation, occupational exposure, MSM, persons who use injection or noninjection illicit drugs, or persons traveling to or working in countries that have endemicity of HAV. In HIV-infected patients, the immunogenicity to HAV vaccination is sub-optimal in HIV-infected patients and the seroconversion rate is estimated 68-90% after administration of 2 or 3 doses of HAV vaccine. Furthermore, the antibody titers of HIV-infected patients following HAV vaccination are significantly lower compared to those of HIV-uninfected persons. The sub-optimal response among HIV-infected subjects remains an unresolved problem. In this study, the investigators aim to determine the to conduct a randomized clinical trial to compare the immunogenicity of 2 different doses of HAV vaccination (1 dose versus 2 doses) in HIV-infected patients who failed to achieve serologic response in the primary vaccination. This proposal will provide the solid evidence to elucidate the role of booster HAV vaccination in HIV-infected patients without response to primary HAV vaccination.
The purpose of this study is to examine the feasibility of an intervention to prevent chronic diseases like diabetes, high blood pressure, and obesity in midlife and older Latino adults living with HIV. The investigators expect that the participant will be in this study for seven months. Participants will be interviewed and asked to take part in walking groups.
Cardiac steatosis is increased among individuals with HIV, and may predispose to cardiac mechanical dysfunction and subsequent heart failure. The pathogenesis and treatment of cardiac steatosis is not well understood. The investigators have previously shown that perturbed growth hormone (GH) secretion in HIV contributes to ectopic fat accumulation in the viscera and the liver. Moreover, the investigators have found that augmentation of endogenous GH secretion with the FDA-approved medication tesamorelin reduces visceral and hepatic fat. In this longitudinal observational study, the investigators will examine patients with HIV and abdominal fat accumulation who either plan or do not plan to initiate tesamorelin prescribed clinically. The investigators hypothesize that blunted GH secretion in HIV is associated with cardiac steatosis. The investigators also hypothesize that use of tesamorelin for 6 months is associated with a reduction in intramyocardial fat and preserved cardiac function.
The purpose of this study is to collect quantitative data related to developing and testing a couple-based intervention (CBI) for HIV-positive women's medication adherence in the region of Kwazulu-Natal, South Africa. The CBI, called START (Supporting Treatment for Anti-Retroviral Therapy) Together, will be a manualized intervention focused on women's ART adherence and enhancing the couple's communication and problem-solving behavior. The study focuses on implementation outcomes (feasibility, acceptability, and fidelity) and preliminary efficacy outcomes (women's ART adherence, men's engagement in HIV care, and the couple's relationship functioning), which will be compared to a control condition of referrals to usual HIV care.
This clinical trial seeks to determine if male-centered recruitment increases men's testing for HIV and whether or not individualized introduction to clinics increases male engagement in treatment for HIV. The study is being conducted in rural KwaZulu Natal.
HIV infection is associated to premature decline of serum testosterone. However, prevalence and biochemical characterization of hypogonadism in HIV-infected men are still to be well defined. HIV-infection is strongly associated to erectile dysfunction in men, but preliminary data suggest that it is poorly associated with serum testosterone in this context.
The study will evaluate the use and effectiveness of mobile-messaging platforms as a public health strategy for improving sexual health outcome measures among men who have sex with men (MSM) by determining whether exposure to the message-delivery platform results in improvements in participants' self-reported sexual health and prevention behaviors, beliefs and attitudes. The study will enroll men into a randomized controlled trial. Participants randomized to the messaging intervention will have access to a smartphone-based messaging platform for three months while those assigned to the waitlist group will be offered access to the messaging platform after all follow up is complete. Participants will complete surveys at baseline, after the end of the 3 month intervention, and follow up surveys 6 and 9 months after the baseline survey.
This study will evaluate the anti-retroviral activity of MK-8527 in HIV-1 infected, ART-naïve participants. The primary hypothesis is that MK-8527 has superior anti-retroviral activity compared to placebo, as measured by change from baseline in plasma HIV-1 ribonucleic acid (RNA) at 168 hours postdose.
