Filter by:The objective of the present study is to analyze the overall tubular function, and in particular that from the proximal tubule and the thick ascending loop of Henle (TALH) in patients with HIV infection receiving or not tenofovir-containing antiretroviral treatment in comparison with seronegative controls, by applying a validated tubular physiological test known as "Low sodium infusion test". Hypothesis is that patients with HIV infection and normal renal function will show subclinical tubular abnormalities compared with seronegative controls
The purpose of this comparative study is to evaluate the efficacy of an ovule with triple active agents (terconazole, clindamycin and fluocinolone) versus another ovule with triple active agents (nystatin, metronidazole and fluocinolone) in the treatment of symptoms caused by the presence of vaginitis (inflammation of the vagina) or bacterial vaginosis (polymicrobial, nonspecific vaginitis associated with positive cultures of Gardnerella vaginalis and other anaerobic organisms and a decrease in lactobacilli).
Proliferative lupus nephritis (LN)is the predominant cause of morbidity and mortality in juvenile Systemic Lupus Erythematosus (SLE). Induction therapy with high-dose intravenous cyclophosphamide can improve renal outcomes, but considerably associated with infection. Although severe infection is the significant complication related to poorer prognosis for juvenile SLE patients in Asia, cyclophosphamide is still commonly used as the drug of choice for severe lupus nephritis. Euro-Lupus Nephritis Trial demonstrated low-dose intravenous cyclophosphamide regimen followed by azathioprine achieved good clinical results comparable with obtained high-dose regimen. There was lower number of severe infection episodes, but no significant difference. Recent studies applied low dose of cyclophosphamide (500 mg/m2/dose or 500 mg/dose)in young patients and showed good renal response. Low-dose intravenous cyclophosphamide regimen might promote non-inferior renal remission whereas decrease risk of serious infection and improve overall patient outcomes.
The purpose of this study is to determine the extent to which bacterial growth in the nostrils by S. aureus, a common bacteria that is found in hospital environment, can be reduced by NOZIN® Nasal Sanitizer® antiseptic nasal swabs during the course of a typical 10-hour work period in participants known to have S. aureus in their nose passages.
Adolescents with mental health (MH) disorders (MHD) have higher rates of HIV/STI sexual risk behaviors than those in the general population. In Brazil, among youth seeking HIV testing, those testing positive had more MH problems than HIV-negative youth; HIV/STI sexual risk reduction is not regularly implemented within MH care for adolescents. Our NIMH-funded RCT in Rio de Janeiro (Rio; R01MH065163; PI: Wainberg) promises to provide such intervention for adults with MHD. A comparable evidence-based HIV/STI prevention intervention for adolescents is not available in Brazil; this application targets this need. Using quantitative and qualitative methods we will explore the contextual influences on sexual risk behavior of Brazilian youth ages 13-24 with MHD to inform intervention adaptation. The investigators will then pilot-test the family-based (parent-adolescent dyad) intervention HIV, STI and pregnancy prevention intervention with a sample of male and female youth age 13-24 years (n=144) with MHD who are in MH treatment in four community-based sites in preparation for the RCT.
This is a study to evaluate the efficacy and safety of three experimental drugs compared with telaprevir (a licensed product) in people with hepatitis C virus infection who have not had treatment before.
The purpose of this study is to evaluate the safety and antiviral activity of 3 direct-acting antiviral agents (DAAs; ABT-450/ritonavir/ABT-267 [ABT-450/r/ABT-267; ABT-267 also known as ombitasvir] and ABT-333 [also known as dasabuvir]) plus ribavirin (RBV) compared with telaprevir (TPV) with pegylated interferon/ribavirin (pegIFN/RBV) in patients with chronic hepatitis C virus genotype 1 (HCV GT1) infection without cirrhosis who were previously treated with pegylated interferon/ribavirin (pegIFN/RBV).
Background: - Pulmonary nontuberculous mycobacterial (PNTM) infection is caused by a common type of bacteria in the environment. Although PNTM infection is most common in people with lung diseases, it can also affect healthy people. It can be difficult to treat, and affects parts of the body other than the lungs. For example, PNTM may affect the cilia, the hair-like structures inside the nose and lungs that help move dirt and debris out of the body. - Ciliary beat frequency (CBF) is a measurement of how fast cilia move. People with PNTM infection have a lower CBF than healthy people. Nitric oxide (NO) is a gas in the body that may affect CBF. People with PNTM infection produce lower amounts of NO in their noses than healthy people. Researchers want to see if a drug called sildenafil can increase NO production and CBF. If sildenafil can improve these measurements, it may be a useful treatment for PNTM infection. Objectives: - To study the effect of sildenafil on CBF and NO levels in people with PNTM infection. Eligibility: - Individuals at least 18 years of age who have PNTM infection. - Participants must be enrolled in a related National Institutes of Health study on bacterial infections. The study is Natural History, Genetics, Phenotype and Treatment of Mycobacterial Infections. Design: - Participants will be screened with a physical exam and medical history. They will also have heart and lung function tests, as well as tests of NO production in the nose. They will provide samples of sputum and cells from inside the nose. - Before the first study visit, participants will collect sputum samples for 24 hours. They will bring the samples to the study visit. - At the first study visit, participants will have heart and lung function tests, as well as tests of NO production in the nose. They will provide blood, urine, sputum, and nasal cell samples. They will also receive sildenafil tablets to take at home. - Participants will take sildenafil tablets three times a day. - The second study visit will be 7 days after the first one. The tests from the first visit will be repeated. Participants will receive more sildenafil tablets to take on the same schedule as before. - The third and final study visit will be 30 days after the first one. The tests from the first visit will be repeated. Participants will stop taking sildenafil at this visit. - A follow-up phone call will be made about 2 weeks after the final study visit. This call will ask questions about quality of life and any symptoms or side effects of the study.
This study was designed to test the hypothesis that treatment of HIV infected subjects with losartan, an agent with specific anti-inflammatory and anti-fibrotic actions, will: 1. reverse existing lymphoid tissue fibrosis, 2. restore lymphoid tissue architecture, 3. increase the number and improve the function of peripheral and lymphatic CD4 T cells, 4. decrease levels of systemic immune activation (IA), 5. decrease size of the HIV reservoir, and 6. be safe and well tolerated.
To evaluate the agreement between NAAT results for Chlamydia trachomatis and Neisseria gonorrhoeae infection obtained with self-obtained vaginal swabs (SOVS), collected in a non-clinical setting vs. NAAT results using SOVS collected in a clinical setting. This is a new use of this specimen type as SOVS are FDA cleared only for use in clinics. The NAAT (Gen-Probe APTIMA Combo 2® Assay (AC2)) result with the home-collected SOVS specimen will be compared to the result obtained with an SOVS collected in the clinic on multiple platforms (Direct Tube Sampling (DTS) / Panther / Tigris). The term "home-collected" is used to refer to any specimen that is not collected in a clinic, since there is no certainty that a specimen is collected "at home" or in a restroom in an office setting, etc. To compare the SOVS results to an FDA cleared predicate test with the collection of two clinician collected vaginal swabs.
