NCT00013520
The purpose of this study is to compare the effectiveness, safety, and tolerability of 3 anti-HIV combination treatments that do not use protease inhibitors (PIs). The current rule for starting treatment of HIV infection is to combine members from different classes of anti-HIV drugs, such as 2 nucleoside reverse transcriptase inhibitors (NRTIs) and either a PI or a nonnucleoside reverse transcriptase inhibitor (NNRTI). However, these combinations can be complicated and difficult to take, can cause a number of side effects, and may become ineffective. Combinations that are simpler, better tolerated, and more effective are needed. Because PIs can cause long-term side effects and because HIV can become resistant to many of them at the same time, anti-HIV combination treatments that do not use PIs are being tested.
NCT00000674
To collect information on the effectiveness and toxicity of clindamycin plus pyrimethamine and leucovorin calcium for the treatment of acute toxoplasmic encephalitis in adult patients with AIDS. Toxoplasmic encephalitis (encephalitis caused by Toxoplasma gondii) is the most frequent cause of focal central nervous system infection in patients with AIDS. If untreated, the encephalitis is fatal. At present, it is standard practice to give a combination of pyrimethamine and sulfadiazine to treat toxoplasmic encephalitis. The high frequency of sulfonamide-induced toxicity in AIDS patients often makes completion of a full course of therapy difficult. There is some information that high doses of parenteral (such as by injection) clindamycin used with pyrimethamine may be as effective as pyrimethamine plus sulfadiazine in the management of the acute phase of toxoplasmic encephalitis in patients with AIDS. Administration of parenteral clindamycin for prolonged periods of time, however, is costly, requires hospitalization, and is inconvenient for the patient. There is some indication that treatment of AIDS patients with acute toxoplasmic encephalitis with oral clindamycin may be effective. Leucovorin calcium is useful in preventing pyrimethamine-associated bone marrow toxicity.
NCT01164605
The substitution of raltegravir for the NRTIs will result in some reversal of the long term adverse effect of lipodystrophy (specifically peripheral lipoatrophy) that is associated with the chronic use of NRTIs. Changing the HAART regimen in patients with a sustained virological response from a PI plus NRTI to a regimen of the PI plus raltegravir will likely result in continued virologic efficacy.
NCT00471614
The purpose of this study is to determine whether uridine supplementation will improve insulin sensitivity and overall carbohydrate metabolism in HIV-positive subjects who are currently undergoing treatment with antiretroviral regimens containing stavudine or zidovudine and who have evidence of impaired mitochondrial function and insulin resistance.
NCT00581802
The purpose of this observational study is to characterize which immune system cells hide the latent reservoir of HIV by counting the number of latent HIV in different subsets of CD4 cells. Observations will also be made on other possible mechanisms of HIV persistence by looking at cellular factors such as APOBEC3 and drug transporters. The purpose of this study is to develop new strategies to reduce and possibly eliminate the latent reservoir in HIV infected adults.
NCT00741975
Adolescents are at risk for HIV because of sexual and drug use behavior initiated during early adolescence, and those with mental health problems appear to be particularly susceptible. Problems with managing emotions may make it difficult for early adolescents to make good decisions about sexual and substance use behaviors. This project will develop and evaluate interventions for early adolescents with mental health issues. An intervention focused on teaching affect management skills will be compared to an intervention addressing a variety of health topics to determine which intervention best reduces risk behavior among this at-risk population.
NCT00147355
This substudy is an open-label, randomised study comparing the uptake of recombinant interleukin-2 (rIL-2) in HIV-1 infected individuals receiving different combinations of antiemetics and analgesic agents during rIL-2 dosing in ESPRIT. The design is a factorial one with 4 arms. All patients will receive regular ibuprofen and paracetamol from days 1-6 of the rIL-2 dosing cycle; in addition, patients will be randomised to receive one of two antiemetic combinations, i.e. ondansetron or metoclopramide with or without low dose codeine phosphate as an additional analgesic agent.

NCT00675389
The provision of antiretroviral therapy (ART) in rural, resource-limited settings entails substantial challenges due to limitations in the health service infrastructure and in human resources for HIV/AIDS care. In addition, long geographical distances between providers, care facilities, and patients can represent a significant barrier to appropriate and timely care. The use of peer health workers as frontline adherence supporters and clinical monitors in order to improve care in underserviced settings has been implemented by a number of programs, but the effect of peer support on HIV care outcomes has not been extensively evaluated. Mobile phones have also been proposed as a potential method of improving access to health care in resource-limited environments by expediting communication and data transfer, but rigorous studies on their effectiveness in Africa have not yet been conducted. The Rakai Health Science Project (RHSP) was founded in 1987 to study the HIV epidemic in the rural setting of Rakai District in southwest Uganda. Since June 2004, the US President's Plan for AIDS Relief (PEPFAR) has enabled the RHSP to provide ART through a community-based distribution system which includes clinical monitoring via a decentralized, mobile clinic approach. By late 2006, the program has screened 4,397 HIV-infected individuals and initiated ART in 849 patients. One of the challenges of providing ART in this setting has been the distance between many patients' homes and the clinic and medical staff trained in HIV care. This distance and the lack of communication channels make frequent clinic contacts difficult and has raised concerns about adherence and management of drug toxicity. This study will investigate whether peer health workers can help support this AIDS care program and improve patient outcomes. This study is a three armed, community-randomized operations research trial to assess the effectiveness of peer health workers, with and without mobile phones, in improving the delivery of HIV care in the resource-limited Rakai setting. The three arms will be: a) communities with peer health workers, b) communities with peer health workers and mobile phones, and c) control communities without peer health workers. Study hypotheses include: * Peer health workers, by supporting adherence and by managing simple clinical issues, will reduce virologic treatment failure and improve ARV adherence compared to patients in communities without peer educators. * Mobile phone technology used by peer health workers, by more rapidly addressing adherence and clinical problems, will reduce treatment failure and improve adherence compared to patients in communities with peer health workers without mobile phones.
NCT00440947
This study was designed to test the efficacy, safety, tolerability and durability of the antiviral response between atazanavir (ATV) + ritonavir (/r) + abacavir/lamivudine(ABC/3TC) Fixed dose combination (FDC) each administered once daily (QD) for 36 weeks followed by randomization to either a simplification regimen of ATV or continuation of ATV +/r for an additional 48 weeks, each in combination with ABC/3TC in antiretroviral (ART)-naive, HIV-1 infected, HLA-B\*5701 negative subjects. All subjects who complete the 84-week study will be eligible to enter the treatment extension phase and continue for an additional 60 weeks. The purpose of this extension is to obtain longer term treatment data in subjects who have completed the 84-week study.
NCT01475227
The study is being conducted as the most common side effect of the HIV drug atazanavir (taken with ritonavir) is hyperbilirubinaemia. Bilirubin is a normal waste product from the body and gets broken down in the liver so it can leave the body through the gut. Atazanavir slows the breakdown of this chemical, which can cause jaundice (yellowing of the skin) and/or scleral icterus (yellowing of the eyes). This is completely harmless; in fact up to 1 in 10 of the UK population have an inherited condition that causes the same yellowing. However, some patients don't like this side effect and it is the commonest reason for switching off the drug. A study in people with Gilberts syndrome (the inherited condition that causes the same changes in the chemical bilirubin) showed that a mineral supplement (zinc sulphate) reduced the levels of bilirubin in the blood. The aim of this study is to see if using zinc supplements can achieve the same effect in patients with high bilirubin due to atazanavir use.
NCT00226434
In Cambodia the prevalence of both tuberculosis (TB) and Human Immunodeficiency Virus (HIV) infection is high. Data suggest that aggressive management of HIV infection, which includes Anti-Retroviral Therapy (HAART) during treatment of TB, decreases both morbidity and mortality. On the other hand, the use of HAART for patients with TB may cause severe complications due to drug-drug interactions, and occasionally a temporary exacerbation of symptoms. These reactions may be particularly severe when HAART is started soon after the start of TB treatment. The proposed study aims to determine the optimal time to initiate HAART in previously untreated HIV-infected adult patients with TB and low CD4 cell counts.
NCT01546376
Objectives: To study immunostatus (CD4) and HIV viral load in HIV-cancer patients before RT and last weeks of RT .
NCT00122616
The aim of this study is to prove the efficacy of peginterferon in HIV infected patients with liver disease caused by hepatitis C virus (HCV) when the treatment to eradicate the virus failed. This scientific proof needs a comparative study to be done including two groups of patients randomly allocated: one with the treatment (peginterferon) and the other without any treatment against HCV with a duration of 2 years. To conclude, two liver biopsies are needed; one before the study and a second 2 years after.
