Filter by:The objective of this study is to test the safety and potential efficacy of ibudilast to treat methamphetamine dependence. The study hypotheses are that ibudilast will reduce methamphetamine use and increase treatment retention more than placebo among patients seeking treatment for methamphetamine dependence. As HIV infection is a common complication of methamphetamine dependence, half of the participants will be HIV positive and the study will assess whether ibudilast also improves HIV related outcomes (e.g. medication adherence, CD4 count, risk behaviors).
The purpose of this study is to evaluate why the majority of HIV infected women in the Harris County Health District system who are pregnant do not come to clinic for their HIV disease after they have a baby through questionaires administered prepartum and questionaires and structured interviews postpartum. The study will ask subjects questions about HIV, drug use, depression and social problems.
This study was designed to test the hypothesis that treatment of HIV infected subjects with losartan, an agent with specific anti-inflammatory and anti-fibrotic actions, will: 1. reverse existing lymphoid tissue fibrosis, 2. restore lymphoid tissue architecture, 3. increase the number and improve the function of peripheral and lymphatic CD4 T cells, 4. decrease levels of systemic immune activation (IA), 5. decrease size of the HIV reservoir, and 6. be safe and well tolerated.
The investigators' objective is to describe the variability of rifampicin absorption, markers of inflammation and gut damage, intestinal absorptive capacity, and intestinal permeability among HIV-infected volunteers. Rifampicin is the least well absorbed of the first-line anti-tuberculosis drugs. Rifampicin malabsorption is frequently observed in HIV-infected patients with active tuberculosis, but cannot be predicted by patient factors such as CD4+ T cell count, viral load, or the presence of diarrhea. The mechanisms for rifampicin malabsorption in HIV-infected patients are unknown. An understanding of mechanisms for rifampicin malabsorption could eventually lead to new therapeutic targets, with the ultimate goal of improving HIV/tuberculosis treatment outcomes.
Cervical cancer is the second most common type of cancer among women worldwide. Women with human immunodeficiency virus (HIV) bear a disproportionate burden of cervical cancer and its precursor, cervical intraepithelial neoplasia (CIN), that result from persistent high-risk Human Papillomavirus (HPV) infection. HIV clinical practice guidelines recommend two Pap tests in the year following diagnosis, and if both are normal, yearly thereafter. Nationally, only 25% of women meet this recommendation. The mean annual Pap testing rate for federally funded HIV centers is only 55.7%. In 2009, quality improvement statistics from the Johns Hopkins Hospital Moore Clinic, a large urban HIV center, revealed an annual Pap testing rate of 59%. This occurred despite interventions to address adherence issues were implemented, including nurse case management, co-location of HIV and gynecology services, flexible scheduling, and continuity of care. Women keep their appointments for HIV primary care more often than for gynecology care in the Moore Clinic, so an intervention that takes place during a primary care visit could improve cervical cancer screening rates. The availability of HPV testing provides a unique opportunity to increase perceived susceptibility to and severity of cervical cancer among women with HIV, and to encourage follow-up Pap testing. HPV testing involves analyzing a sample of cervicovaginal cells for the presence of high-risk HPV strains. Detection of high-risk strains of the virus indicates a high risk for high grade CIN and cancer, while a negative HPV test predicts a less than 2% risk of developing CIN. HPV testing can be easily conducted by women themselves through self-collection in a primary care visit. Studies of women without HIV who do not have regular Pap testing have demonstrated that self-collected HPV testing and results counseling increases the overall screening rate, and women who test positive for HPV have a high rate of follow-up Pap testing. Self-collected HPV testing and results counseling could be utilized in the HIV primary care setting to promote Pap testing among women with HIV.
Access to highly active antiretroviral therapy can improve maternal health outcomes for the 4000 HIV- infected women who give birth daily and nearly eliminate transmission of HIV to their infants. However, system inefficiencies, particularly CD4 testing to determine treatment eligibility, are barriers. The project aims to study the effectiveness of a programmatic intervention at improving antenatal access to treatment.
Our general goal is to evaluate the potential effectiveness of recombinant lactoferrin (1500mg bid) for reducing inflammation among HIV positive participants.
To date, all work related to the study of HIV tropism, was performed on HIV B and C subtypes. In the studied samples, HIV variants of subtype A were virtually absent. However, the existence has been shown previously of some differences in the nucleotide sequences in the V3 loop of env region of subtype A from other subtypes of virus. In the Russian Federation the subtype A of HIV-1 is predominant, and, according to some estimates, accounts for about 89% of all newly diagnosed cases of HIV infection. Thus, it seems interesting and effective to study the characteristics of HIV-1 subtype A, associated with the tropism, in the Russian Federation. The primary objective is determination of the prevalence of R5 (chemokine receptor 5), X4 (chemokine receptor 4), and R5X4-tropic variants of HIV in HIV-infected population in Russia, and analysis of the possible features of tropism of viruses belonging to subtype A.
This phase I trial studies the side effects and best dose of cabozantinib s-malate in treating patients with solid tumors that have spread to other places in the body and usually cannot be cured or controlled with treatment and human immunodeficiency virus. Cabozantinib s-malate may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.
Hypothesis: the Telaprevir(TVR) plasma levels (750 mg q8h or 1125 mg/12h )will not be affected when co-administered with un-boosted Atazanavir (ATV) 200 mg q12h plus two analogues (NRTIs) in HCV/HIV-co-infected patients.
