Active clinical trials for "Acquired Immunodeficiency Syndrome"

The prevalence of HIV-associated wasting declined dramatically with the introduction of effective antiretroviral therapy (ART), but as patients survive longer on treatment the proportion of overweight (body mass index [BMI] >25 kg/m2) and obese (BMI >30 kg/m2) HIV-infected individuals has been rising over time and is reaching parity with the general population. Adipose tissue has broad effects on immune function relevant to HIV infection, including the basal inflammatory state and peripheral lymphocyte populations, but there are few data on the effects of high adiposity on HIV immunology. This issue is directly relevant to promoting the long-term health of ART-treated individuals, many of which can now survive for decades on treatment, as emerging evidence suggests that increased immune activation is a major risk factor for the development of cardiovascular and metabolic diseases in this population. HIV-infected individuals on ART have an approximately 2-fold higher risk of myocardial infarction and a 4-fold higher risk of type 2 diabetes mellitus, and the proportion of deaths among HIV-infected individuals due to non-AIDS conditions now exceeds those due to AIDS. Despite the increasing proportion of overweight and obese HIV-infected persons, few prior studies have investigated the interaction between adipose tissue, immune activation, and risk factors for cardiovascular and metabolic disease in treated HIV. The overall goal of this study is to understand the complex relationships between adipose tissue, innate and cellular immune activation, and metabolic and cardiovascular disease risk factors in persons on long-term antiretroviral therapy. To this end, we will use an observational, cross-sectional cohort design to compare in vivo markers of immune activation, ex vivo cytokine expression, and metabolic and cardiovascular disease markers in HIV-infected individuals with a range of body composition profiles and between overweight/obese HIV-infected and uninfected individuals.

HIV is concentrated among key populations in Myanmar. Globally, HIV-prevalence among transgender (TG) women is one of the highest; laboratory-confirmed prevalence is reported up to 40%. In September 2015, WHO recommended the use of Pre-Exposure Prophylaxis (PrEP) for people at substantial risk of HIV as part of a combination HIV prevention strategy. A demonstration project will take place to implement and evaluate the uptake and effectiveness of PrEP among MSM, and TG women in a clinic in Hlaingtharyar township, Yangon. The aim is to describe PrEP uptake, as well as HIV-seroconversion and STI infection rates among those who use PrEP.

The second Swaziland HIV Incidence Measurement Survey (SHIMS 2, 2016), is a population based HIV Impact Assessment (PHIA) that will assess the prevalence of key human immunodeficiency virus (HIV)-related health indicators. This is a two-stage cluster sampled cross-sectional survey of 6,417 randomly selected households in Swaziland. Approximately 20,292 eligible persons will be approached (4,664 participants 0-14 years; 12,563 participants 15-49 years; 3,065 participants 50 years and older). Of the sample approached, 15,403 are expected to agree to a blood draw for home-based HIV rapid testing including 3,361 participants 0-14 years; 9,680 participants 15-49 years; and 2,362 participants 50 years and older. SHIMS 2, 2016 will characterize HIV incidence, prevalence, viral load suppression, cluster of differentiation 4 (CD4) T-cell distribution, and risk behaviors in a household-based, nationally-representative sample of the Swazi population and will describe uptake of key HIV prevention, care, and treatment services.

The purpose of this study is to investigate the tolerability of Kaletra (lopinavir/ritonavir) in combination with new substances such as integrase inhibitors (INIs), C-C chemokine receptor type 5 (CCR5) antagonists, and new non-nucleoside reverse transcriptase inhibitors (NNRTIs), as there are many reasons (intolerability, complex resistant patterns or even personal reasons) which may result in a change from the daily clinical routine and lead to the use of a newly approved antiretroviral agent in combination with Kaletra.

This non-interventional, post-marketing observational study was conducted to obtain data, such as safety and effectiveness, from the use of lopinavir/ritonavir (Kaletra) in clinical practice and investigate the necessity to conduct a follow-up post-marketing clinical study in Japan.

The objective of this study is to observe and collect data on the usage, dosing, tolerability, and effectiveness of Kaletra (lopinavir/ritonavir) tablets in human immunodeficiency virus (HIV)-infected patients. In some patients, the study is to show the impact on tolerability of changing therapy to Kaletra tablets from other regimens.

APV10017 was a pharmacokinetic study that evaluated the pharmacokinetics, safety and tolerability of fosamprenavir/ritonavir (FPV/RTV) at reduced doses over 14 days in HIV-infected subjects with mild to moderate hepatic impairment (HI). Based on these data, two new regimens have recently been approved by the EMEA and FDA in these patient groups; FPV 700mg BID/RTV 100mg QD for those with mild HI (Child-Pugh score 4-6) and FPV 450mg BID/RTV 100mg QD for those with moderate HI (Child Pugh score 7-9). The Committee for Medicinal Products for Human Use (CHMP) has requested longer-term safety data among this hepatically impaired HIV-infected population who have received the recently updated FPV/RTV dosing regimens. An observational cohort study will be conducted using routinely collected data in three European HIV patient cohorts with a high proportion of hepatitis co-infected individuals. Patients who received FPV/RTV will be followed to address the following objectives. Primary: To assess the safety and tolerability of FPV/RTV-based ART in subjects with mild to moderate hepatic impairment. Secondary: A). To compare the safety and tolerability of FPV/RTV-based ART in subjects with mild to moderate hepatic impairment when compared to FPV/RTV-based ART in hepatitis B (HBV) or hepatitis C (HCV) co-infected subjects with normal hepatic function. B). To compare the safety and tolerability of FPV/RTV-based ART to lopinavir/ritonavir LPV/RTV-based ART in subjects with mild to moderate hepatic impairment.

To reassess nutritional status of HIV-infected Thai children living in the family style community after receiving nutrition support program for 6 months.

To investigate the effect of treatment of HIV infection with highly active antiretroviral therapy on individual steps of reverse cholesterol transport, endothelial function and intima-media thickness in HIV patients.

The objective of this surveillance is to collect information about 1) adverse drug reaction not expected from the LPD (unknown adverse drug reaction), 2) the incidence of adverse drug reactions in this surveillance, and 3)factors considered to affect the safety and/or efficacy of this drug.
