Active clinical trials for "HIV Seropositivity"

This protocol describes the Cohort Assessment phase of an R34 pilot intervention trial of a Peer Navigation (PN) intervention tailored to the needs of HIV-positive MSM in rural Mpumalanga province South Africa. The PN intervention to be adapted, I-Care, has been implemented among HIV-positive men and women in the general population in North West province, South Africa, by members of this research team.

Evaluation of the impact of initiation of protease inhibitor/ritonavir on PCSK9 levels in HIV-infected antiretroviral-naïve patients from the ANRS C09 COPANA cohort.

Dental implants are widely used in human immunodeficiency virus (HIV)-positive patients, but the interaction between immune status and success of implant therapy, especially in such patients, is not clear. This study aimed to assess the prevalence of peri-implantitis in HIV-positive patients and to evaluate the presence of a possible correlation between the immunological profile and serological values of the same HIV-positive patients, of peri-implantitis, and of possible differences between all-on-4 and single crown/bridge prostheses in terms of peri-implant disease and the variables analyzed. This cross sectional study included 85 adult HIV-positive patients (394 implants) with at least one dental implant loaded for more than a year who were followed for at least one year. The patients were divided into patients with all-on-4 prosthesis and those with single crowns/bridges to assess the differences between the two types of prostheses in the inflammatory state, in the presence of mucositis and peri-implantitis, and in the variables analyzed. The following clinical parameters were assessed: full-mouth plaque score (FMPS), full-mouth bleeding score (FMBS), probing pocket depth (PPD) in six sites per implant and tooth (deepest value for each implant and tooth was registered), PI and BoP measured as presence/absence at six sites per implant and tooth, presence of suppuration, mobility (measured by manual palpation) and number of lost teeth.

The purpose of this study is to find out if antiretroviral drugs are safe and well tolerated by HIV-positive pregnant women and their infants in South Africa and Zambia.

The purpose of this study is to see how taking certain anti-HIV drugs affects the way the body metabolizes fat. This study will evaluate patients who are enrolled in CPCRA 058 (the FIRST [Flexible Initial Retrovirus Suppressive Therapies] study) by looking for changes in cholesterol levels, levels of fat in the blood, and body fat distribution. Patients in the FIRST study receive an anti-HIV drug regimen which contains a protease inhibitor (PI), a nonnucleoside reverse transcriptase inhibitor (NNRTI), or both. Anti-HIV drug therapy using PIs has become very common treatment for HIV-positive patients. Recently, however, serious side effects involving how the body uses fat are being reported in patients taking PIs. Examples of these side effects are a redistribution of body fat, high cholesterol level, and development of diabetes. However, some of these side effects have also been seen in patients who are not taking PIs. It is important to determine whether or not these side effects are directly related to PI use. In this study, patients on different drug combinations, either with or without a PI, will be compared.

Adapted athletic activity has shown benefits in patients with certain chronic diseases, including improving fatigue and pain in patients with cancer, and improving the symptoms of severe depression. Among Patients Living with Human Immunodeficiency Virus (PLHIV), sport appears to be less common than for people who do not live with HIV. In fact, 44% of PLHIV in a Swiss cohort (10,500 patients) were inactive in 2014, whereas this percentage was 26% in the general population in Switzerland. We did not find any French data on the prevalence of sports activity among PLHIV. The benefits of sport in PLHIV are numerous: meta-analyzes on interventional studies of aerobic and resistance exercises show a significant improvement in maximum oxygen consumption, muscle strength, percentage of body fat, quality of life and symptoms of depression. An improvement in cognitive function was noted in a randomized study. An Iranian randomized study of 2017 showed an improvement in the CD4 count, after 8 weeks of resistive exercise, but two meta-analyzes of 2016 and 2017 did not find a significant change in CD4 or viral load with physical exercise. On the other hand, several studies have shown that sports practice improves self-esteem. In addition, an Australian randomized study in 2006 showed an improvement in self-efficacy in PLHIVs after a six-month exercise (aerobic and resistance) program. Furthermore, self-esteem (defined as positive self-esteem) is a factor facilitating adherence to antiretroviral therapy. The objective of this descriptive study is to evaluate the prevalence of sports activity in a French adult population infected with HIV and to seek an association with self-esteem. In addition, the investigators will look for an association between sport and fatigue, pain, sleep, lymphocyte T CD4 cell levels, viral load.

Efficacy of etravirin + raltegravir dual therapy was showed in the ANRS 153 ETRAL protocol, in HIV-1 seropositive patients. The use of these two drugs avoids the use of nucleoside reverse transcriptase inhibitors and protease inhibitors, with a real benefit in older patients, who increasingly present contraindications to these drugs' families. The disadvantage of this strategy is twice daily (BID). Pharmacological data suggest that etravirine once a day and raltegravir once a day may provide the same virological efficacy. The objective of our study is to evaluate the ability of ETRAL QD (etravirine 400 mg x1/day + raltegravir 800 mg x1/day) to maintain virologic success at week 48 (W48), after switch, in HIV-patients under ETRAL BID (etravirine 200 mg x2/day + raltegravir 400 mg x2/day). Virological success is defined as absence of virological failure, and virological failure is defined as two consecutive plasma viral loads >50 cp/ml over 2-4 weeks, or one plasma viral load >400 cp/ml. This study will be a multicentric data collection. Data will be collected at W0 (patient characteristics, plasma viral load) and then at W4, W12, W24 and W48 (plasma viral load). If stopping strategy, the reason for stopping will be documented. 125 patients will be included in the six participating centers. Data will be centralized at Pitié-Salpêtrière hospital, Paris, with an anonymized e-CRF.

The greatest burden of the HIV-1 epidemic lies in sub-Saharan Africa, where a substantial proportion of infections occur in long-term heterosexual HIV-1 serodiscordant partnerships. Such couples face a difficult dilemma when considering their desire to have children: forego condom use, attempt to conceive and risk HIV-1 transmission or continue condom use and relinquish their childbearing desires. Based on evidence from rigorous clinical trials demonstrating the strong efficacy of individual interventions for HIV-1 prevention and formative work with HIV-1 serodiscordant couples and clinicians with expertise in HIV-1 prevention and reproductive health in the Kenyan context, this study pilots a safer conception intervention that focuses on antiretrovirals (as antiretroviral therapy [ART] taken by the HIV-1 infected partner and pre-exposure prophylaxis [PrEP] taken by the HIV-1 uninfected partner) and timed condomless sex. Additional strategies for couples include diagnosis and treatment of STIs and male circumcision. mHealth tools, including SMS and mobile applications are novel and very popular among Kenyans to ease the burden of addressing health problems. This safer conception intervention incorporates mHealth tools to improve couples' experiences tracking fertility indicators and communicating with providers about their readiness to practice safer conception. SMS surveys to collect daily information from women about their fertility signs and SMS messages are used to reinforce HIV-1 prevention, including condom use for couples during periods that do not have a high likelihood of fertility. An in-clinic mobile application is used to improve clinician-patient counseling and assessments of couple readiness to practice safer conception. To inform future engagement of mHealth tools, the investigators will prospectively evaluate clinician and patient experiences using SMS surveys and the tablet application. Couples with immediate fertility intentions will be followed longitudinally, allowing careful tracking of pregnancy and HIV-1 incidence. The study takes place in Thika, Kenya.

Raltegravir (RAL) is a preferred option for initial antiretroviral therapy in the most recent HIV Treatment Guidelines and is emerging as a popular choice for use in the specialized population of HIV-infected patients being considered for solid organ transplantation. Data from HIV-infected persons with normal organ function have revealed few raltegravir-associated metabolic complications compared to older antiretrovirals, and in general, drug-drug interactions with raltegravir are infrequent. The absence of such concerns appears to make raltegravir a potentially appealing option for antiretroviral therapy in HIV-infected patients being considered for solid organ transplantation. At present, however, little is known of the safety and long term tolerability of RAL-containing regimens in persons undergoing solid organ transplantation. As more HIV-infected patients undergo organ transplantation, there is a growing need for good data on such things as the effect of dialysis on RAL concentrations, the potential interactions with commonly used immunosuppressive drugs, and the pharmacokinetic (PK) /pharmacodynamic (PD) characteristics in those with end stage organ failure, as well as those with functioning grafts. The proposed study will also examine transplant function and survival in HIV-infected patients receiving RAL-containing ART and will compare it to HIV negative historic controls.

HIV+ patients are considered at risk for excessive bone fragility. Several factors could contribute: age, male sex, low body mass index (BMI), HIV infection per se, vitamin D deficiency, using tenofovir/a protease inhibitor (time on and/or current use). Tenofovir is used in a backbone of nucleosides/nucleotides analogues with emtricitabine (FTC), licensed as TRUVADA®, or without this analogue, licensed as VIREAD®. FTC closely resembles lamivudine (3TC) but is 5-fluorinated, the daily intake of fluoride is ~15 mg. Fluoride induces bone formation by stimulating osteoblasts, of often impaired bone quality. The aim of the study is to compare in a cross-sectional design fluoride levels, bone renewal, bone mineral density (BMD) in HIV+ male patients treated by TRUVADA® or VIREAD® for more than 60 months. The patients will be randomly selected, then matched according to age, ethnic origin, BMI.
