Active clinical trials for "Acquired Immunodeficiency Syndrome"

To determine the clinical efficacy of indinavir sulfate or placebo in combination with zidovudine ( AZT ) and lamivudine ( 3TC ) in AIDS patients. Protease inhibitors such as indinavir sulfate may be effective in patients with advanced HIV disease who have received prior AZT therapy. Since studies suggest that triple drug therapy may have an advantage over both monotherapy and two drug therapy, the combination of indinavir sulfate with AZT and 3TC should be evaluated.

To compare two different routes of intermittently administered rhIL-2 with a highly active antiretroviral regimen (HAART) to HAART alone. The comparison is based on the following: proportion of patients achieving at least 50-percent increase in CD4 counts above prerandomization baseline values after 1 year of rhIL-2 and the rate of change in CD4 counts. To compare the safety and tolerance of these regimens and their effect on quality of life. To assess the effects of rhIL-2 when combined with HAART on changes in immune cell phenotypes and function and on HIV viral load and the rate of antiviral drug resistance development. The poor responsiveness of late stage HIV-infected patients to rhIL-2 is thought to occur because of low T cell regenerative capacity and high viral burden. If means were available to effectively suppress virus replication, the indigenous immune restorative responses of the host may be further stimulated and enhanced by rhIL-2. The use of protease inhibitors with nucleoside-analogue combination regimens appears to be most effective in controlling virus replication. High-dose intermittent rhIL-2 administered either intravenously or subcutaneously has been shown to be effective in inducing CD4 responses in a number of studies.

This trial tests the safety and effectiveness of the early use of combinations of anti-HIV drugs in HIV-infected infants and young children in an effort to block virus growth and preserve normal immune functions. Various anti-HIV drug combinations need to be tested in order to find the best way to treat infants and children who have been infected with HIV during birth.

To test whether zidovudine (AZT) is useful as a treatment for the neurologic syndrome called AIDS dementia complex. To determine how long AZT takes to reach cerebral spinal fluid (CSF), how long, and at what concentration it is found there. HIV infection can result in impairment in the function of the brain and spinal cord, leading to disturbances in the ability to think clearly and in strength and coordination. This disorder, which has been called the AIDS dementia complex, may be due to a direct effect of HIV on the nervous system. It is known that AZT does get into the brain to some extent, where it may reduce growth of HIV. It is hoped that AZT will stabilize or improve the symptoms of the AIDS dementia complex.

PRIMARY: In Phase I, to define a broadly tolerable dose of isotretinoin that can be used in combination with interferon alfa-2a (IFN alfa-2a). In Phase II, to determine trends in efficacy of isotretinoin alone or in combination with IFN alfa-2a as chemoprevention (preventing progression or recurrence) of anal intraepithelial neoplasia ( AIN ) / squamous intraepithelial lesions ( SIL ) in patients with HIV infection. SECONDARY: To evaluate the effects of isotretinoin alone or in combination with IFN alfa-2a on immune function markers, human papillomavirus (HPV) type, and HPV DNA levels. Patients with HIV infection have a significant risk of recurrence following local ablation of intraepithelial neoplasia; thus, anogenital epithelial may become an increasingly important cause of morbidity, and possibly mortality, as the HIV epidemic matures. Clinical studies of non-HIV-infected subjects have established that synthetic retinoids inhibit the progression of epithelial preneoplastic conditions and some neoplastic states.

Disseminated infection with Mycobacteria avium complex (MAC) is one of the most common systemic bacterial infections in advanced stages of the acquired immunodeficiency syndrome (AIDS). Current therapy for disseminated MAC infection in HIV patients consists of multidrug chemotherapy regimens are often accompanied by toxicities, and many patients become intolerant of one or more agents. Macrolides are the essential component of successful therapy, yet macrolide resistant strains are being recognized with increasing frequency. Thus, there is an interest in identifying additional therapeutic interventions for disseminated MAC in HIV-infected patients. Interleukin-12 (IL-12) is a central, regulatory cytokine in cell-mediated immunity. IL-12 enhances the cytolytic activity of cytotoxic T and NK cells, and induces interferon-gamma (IFN gamma) production from T and NK cells. This open-label Phase I study is designed to evaluate the safety and immunologic/microbiologic effects of interleukin-12 administration in HIV-infected patients with concomitant disseminated Mycobacterium avium (MAC) infection. Fifteen patients with documented disseminated MAC will be randomized to receive double-blinded placebo or escalating doses of IL-12 in addition to anti-MAC chemotherapy and standard anti-retroviral therapy for six weeks. IL-12 will be administered subcutaneously, with escalating doses every month over the dose range of 30 ng/kg, 100 ng/kg, and 300 ng/kg, or until an individual maximum tolerated dose (IMTD) is reached. Should a patient receive 2 consecutive blood cultures negative for MAC during the course of the study at a lower dose, then he/she will not be further dose escalated. Those patients receiving placebo after 6 weeks will be crossed over to receive the full treatment course of IL-12. Each new dose or dose escalation will take place on an inpatient basis. Once a patient is clinically stable at a dose, the patient will be maintained at that dose as an outpatient for the remainder of the month. Total IL-12 administration will not exceed 12 weeks, or 24 total doses.

This study is intended to evaluate: Any changes in the gut microbiome from baseline compared to end of study in both healthy (HIV-negative) subjects and HIV+ patients with or without chronic diarrhea, following one month of treatment with crofelemer (Mytesi), delayed release 125 mg tablets twice daily (BID) following one month of treatment. The safety and tolerability of crofelemer, (Mytesi) delayed release 125 mg tablets BID in healthy (HIV-negative) volunteers and HIV+ patients following one month of treatment.

The aim of this study will be to verify effects of resistance training in people living with HIV/AIDS.

Transgender women (assigned 'male' at birth but who do not identify as male) are disproportionately impacted by HIV and have culturally unique barriers and facilitators to engagement in HIV care. Transgender women living with HIV (TWH) are less likely than others to take antiretroviral therapy (ART), and those who initiate ART have lower rates of ART adherence, lower self-efficacy for integrating ART into daily routines, and report fewer positive interactions with health care providers than non-transgender adults. As a result, TWH have an almost three-fold higher viral load than non-transgender adults in San Francisco; in Los Angeles, TWH are less likely to be virally suppressed than any other behavioral risk group. In formative work, the investigators have identified culturally-specific and modifiable barriers to HIV treatment engagement among TWH, including prioritization of transition-related health care (i.e. hormone therapy) at the expense of HIV treatment, avoidance of HIV care settings due to past negative health care experiences, misinformation about ART including potential drug interactions with hormones, intensified HIV stigma, low levels of social support, and poor coping skills. There are both individual and public health consequences to poor engagement in care among TWH stemming from high transmission risk factors, including substance abuse, high numbers of sex partners, engagement in sex work, and high rates of mental illness. These findings strongly suggest that TWH face unique challenges to engaging in and adhering to HIV treatment, and that the public health consequences for poor engagement in this population are of grave concern. Interventions to mitigate these barriers to engagement in care are critical in efforts to alter the pattern of HIV-related disparities that lead to disproportionately poor health outcomes for this highly vulnerable and marginalized population. The investigators are conducting a randomized controlled trial of a theory-driven, population-specific, piloted intervention to improve engagement in care for TWH. Grounded in the investigators' Models of Gender Affirmation and Health Care Empowerment, the proposed research is the first to systematically intervene on complex barriers to optimal engagement in HIV care for TWH. The investigators have developed and piloted the Healthy Divas intervention to optimize engagement in HIV care for TWH at elevated risk for treatment failure and consequential morbidity, mortality, and transmission of HIV.

This is a cluster randomized trial to determine whether a package of care including rapid antiretroviral therapy (ART) initiation, as compared to standard ART initiation, improves mortality, retention in care and viral suppression among treatment naive people living with HIV (PLHIV) in Nepal. Package of care includes immediate screening and treatment of opportunistic infections (OIs), rapid ART initiation and enhanced retention in care using mobile health (mHealth) and weekly/biweekly home-based adherence/ retention support linked to community care centre. Standard of care includes screening and management of common OIs, baseline assessment (CD4, viral load and other tests), antiretroviral drugs and ART follow up.
