Filter by:A study concerning viral kinetic with 10 co-infected HIV-HCV patients on treatment with peginterferon alfa-2a + ribavirin o IFN + ribavirin was reported in Conference on Retroviruses and Opportunistic Infections 2002 by Dr. Torriani shown half-life of HCV virions and the viral clearance was larger than mono-infected patients. The doubt is if this difference in viral kinetic of HIV-HCV co-infected patients versus mono-infected is related with the loss of profited on treatment. In the APRICOT trial patients genotype 2/3 were treated for 48 weeks and the relapse rates was only 2%. The present study want to evaluate is the treatment extent for 24 weeks more in patients genotype 1 and/or 4 will be improve the percentage of patients with viral clearance at the end of the follow-up period, to prevent relapsed in patients with response at the end of treatment. Patients will be randomized to received 180 µg/week of peginterferon alfa-2a + 1000-1200 mg/day of ribavirin during 24 weeks more or control.
This research study will examine the usefulness of groups in reducing stress and helping individuals with HIV to stay healthy and avoid problems associated with sexually transmitted diseases. We hope to discover whether being in a group is effective in reducing stress-related symptoms and promoting healthy behaviors.
Basing in studies which have related the darunavir (DRV) virtual inhibitory quotient (vIQ) with the virological response, it is possible to think in the possibility of simplifying the rescue treatment with DRV/ritonavir to 900/100 mg once a day in those patients who are being treated with DRV/ritonavir 600/100 mg twice a day and who, besides having undetectable viral load, have a vIQ over 2. This strategy would not jeopardize the efficacy of the antiretroviral treatment and would have less impact in the lipid profile of the patients as well as less pharmaceutical expenditure.
Highly active antiretroviral therapy (HAART) has led to better health and survival rates among people with HIV/AIDS. The purpose of this study was to measure the effect of trained partner supervision when taking medication versus self-administered therapy in HIV infected participants. These participants have had their first virologic failure on a non-nucleoside reverse transcriptase inhibitor (NNRTI)-based HAART regimen and were starting a protease inhibitor (PI)-based HAART regimen at study entry.
This randomized clinical trial will examine the effectiveness of a strategy of HIV and Hepatitis Care Coordination (HCC) consisting of testing, education, counseling and vaccination for methadone maintenance patients compared with standard Testing, Education, and Counseling (TEC).
Assessing the Efficacy and Long-Term Safety of a 2 mg dose of TH9507, a Growth Hormone-Releasing Factor Analog, in HIV Subjects with Excess Abdominal Fat Accumulation
Tipranavir is a drug with a high antiretroviral activity, also in presence of major mutations in the protease gene. However, its necessity of being co-administered with 400 mg of ritonavir daily, limits its efficacy for the treatment of HIV-infected patients, due to the high incidence of gastrointestinal adverse events. Nevertheless, tipranavir plasma though concentrations were higher than the proposed minimum effective concentration for patients with previous experience with protease inhibitors (PI) in half of patients treated with tipranavir/ritonavir at 500/100 mg dose every 12 hours. Furthermore, when the number of mutations in the protease gene is limited, there are no differences in the reduction of the viral load between patients treated with tipranavir/ritonavir at 500/200 mg and 500/100 mg every 12 hours. At last, the efficacy of tipranavir treatment has been more closely related with the inhibition quotient (IQ) than with concentrations considered isolated. Considering the previous arguments, it can be hypothesized that, basing in every subject IQ, it could be possible to identify those patients HIV-infected in treatment with tipranavir/ritonavir at 500/200 mg every 12 hours that could take advance of the reduction of ritonavir to 100 mg every 12 hours, without compromising the viral replication control. This strategy could improve the tolerability to the treatment, what could result in a better adherence and less proportion of treatment abandon due to this reason
This is a multicenter, open, prospective and randomized study aimed at evaluating the pharmacokinetics of the tablet formulation of lopinavir/r administered in combination with two nucleoside analogs to HIV-infected pregnant women at two different dosages: - Group 1 (standard dosage): 200/50 mg lopinavir/r, 2 tablets every 12 hours, plus two nucleoside analogs. - Group 2 (increased dosage): 200/50 mg lopinavir/r, 2 tablets every 12 hours until the end of the second trimester of gestation (24 weeks) and 3 tablets every 12 hours in the third trimester (from 25 weeks on), plus two nucleoside analogs. Treatment will be initiated at any time between 14 and 30 weeks of gestation and will be maintained for at least 6 weeks after delivery. The objectives are: - To compare the pharmacokinetic parameters of the standard and increased dosage of the tablet formulation of lopinavir/r during pregnancy. - To determine whether the standard and/or increased dosage of the tablet formulation of lopinavir/r during pregnancy confers the same exposure to the drug as that observed in the same women after the end of pregnancy and in historic controls. - To evaluate the transplacental passage of lopinavir/r based on the ratio between the serum concentration in maternal blood at the time of delivery and in cord blood of the two drug dosages (standard and increased) administered during pregnancy. - To evaluate the tolerability of the two lopinavir/r dosages (standard and increased) during pregnancy. - To describe the vertical transmission rate of HIV to the children of the pregnant women included in the study.
Human papillomavirus (HPV) is the most common sexually transmitted disease in the world. HPV infection can cause genital warts and certain cervical problems, including cervical cancer. HPV infection may be more severe and harder to treat in HIV-infected people. The purpose of this study was to determine whether the quadrivalent HPV vaccine is safe, tolerable, and effective in producing antibodies to HPV in HIV-infected women.
One subgroup of adolescents at particular risk for HIV is those with psychiatric disorders. Furthermore, those with histories of sexual abuse have been found to have riskier attitudes, poorer sexual communication skills, and less consistent condom use than non-abused peers. This study implemented and evaluated interventions for adolescents in intensive psychiatric treatment settings, particularly those with histories of sexual abuse. It is hypothesized that those participating in the intervention that addresses affect management and cognitive monitoring strategies will show fewer HIV-risk related behaviors and attitudes at posttest than peers in an information-based intervention.
