Filter by:Highly active antiretroviral therapy (HAART) transformed a once fatal condition into a chronic, manageable condition. However, it is estimated that 20-40% of patients on 2nd line treatment (2 nucleotide reverse transcriptase inhibitors [NRTIs] and a boosted protease inhibitor [PI]) are failing treatment. Figures are thought to be higher in children and adolescents. The reason why patients are failing 2nd line treatment is not exactly known. Failure has been previously attributed to poor adherence. However, some literature shows that some patients on boosted PIs achieve and maintain viral suppression despite suboptimal adherence (adherence of 80- 95%). Viral factors, like drug resistance, are also implicated in treatment failure. However, boosted PIs have high genetic barrier to clinically significant mutations. Therefore, a virus would have to harbour multiple PI mutations for the virus to have reduced susceptibility to boosted PI regimens. Pharmacological factors such as suboptimal dosing, impaired absorption and drug interactions may also be responsible for treatment failure. If sub-optimal adherence is the reason why children are failing 2nd line treatment, then restoring optimal adherence should result in viral suppression, failure of which might mean that other causes are contributing to failure. If resistance is the cause of treatment failure, then this study will provide evidence for advocating for resistance testing and the use of 3rd line antiretroviral drugs. If children with adequate adherence demonstrate inadequate drug levels in their plasma, then this study will provide evidence to advocate for studies to examine reasons for inadequate drug exposure amongst HIV-infected children. These studies are paramount to optimizing dosing algorithms in this population. This proposed study will help elucidate reasons for treatment failure in HIV-infected children on second line treatment with the aim of ultimately optimizing antiretroviral treatment strategies for this important group.
The purpose of this study is to describe the long-term surgical success, quality of life, prevalence of depression, fertility rates, and pregnancy outcomes of patients who have undergone obstetric fistula repair. This will be a study involving up to 300 women 1-3 years after they have undergone obstetric fistula repair at the Fistula Care Center in Lilongwe, Malawi. Patients who underwent obstetric fistula repair between January 1, 2012 and July 31, 2014 will be identified from an existing database of fistula patients. They will then be contacted and invited to participate in the study. Consented patients will complete a 1-hour pad weight to evaluate urinary continence, a demographic questionnaire, an incontinence-related quality of life metric, and a depression metric. The data will be analyzed and then disseminated to stakeholders.
A subset of patients with NAFLD that have not been extensively studied are those infected with human immunodeficiency virus (HIV). Currently, there is no FDA approved treatment for NAFLD or NASH. Additionally, there have been no significant clinical trials for HIV patients with NAFLD and there are no approved treatment options. We plan to conduct a randomized, double-blinded, placebo-controlled clinical trial to examine the efficacy of 600 mg of Aramchol daily (including 200 mg tablet and 400 mg tablet) versus identical placebo given over 12 weeks to improve HIV-associated hepatic steatosis as measured by a validated and accurate magnetic resonance imaging (MRI)-based technique.
The objective of this study was to determine the effectiveness of mobile phone technology (SMS and telephone call reminders) in improving adherence and treatment outcomes among HIV positive patients on ART in Malaysia.
This supplement study is an adaptation of the larger NIH-funded parent study, the Women's Health CoOp+, which tests a combination biobehavioral HIV prevention approach to enhance standard HIV testing practices for alcohol and drug (AOD)-using women across the city of Pretoria, South Africa. The current supplemental study seeks to reach AOD-using female adolescents who experience the greatest burden of new HIV infections and are currently underserved by HIV and drug-treatment programs in Cape Town, South Africa and test the validation of both the instrument and adapted intervention.
This developmental research grant award (R21) requests funds to explore the feasibility and impact of a public health system PrEP intervention in a recently emerging HIV epidemic in Athens Greece. The investigators propose a modeling approach using an Agent Based Model (ABM) that moves beyond basic pathogen and transmission patterns to dealing with complex social interactions, including overlapping social and sexual networks as well as implementation realities, like finite PrEP resources, delayed linkage to PrEP care and early PreP care retention based upon empirically collected data in Athens Greece.
Inadequate adherence to antiretroviral therapy (ART) can impede successful viral suppression and consequently lead to negative health consequences. This study aims to refine and test the efficacy of a mobile health ART adherence application (ARTAA), delivered over a smartphone, with helping individuals improve their ART adherence.
The aim of this study is to identify reproductive health priorities among individuals living with HIV.This study also seeks to explore factors that influence fertility, family planning, and sexual behavior among individuals with HIV who are receiving antiretroviral therapy (ART).
The aim of this study is to compare the biomarkers levels as IL-18, KIM-1 and Cystatin C for patients infected by HIV with failure in renal function at year 5. The main criterion will be a degradation of the glomerular filtration throughput measured. It will be compared to clinical scores of degradation risks of renal function for patients infected with HIV.
Testosterone deficiency is classically associated with the development of metabolic syndrome, osteoporosis, erectile disorder and / or a reduced libido, a depressive syndrome and alteration of the quality of patients life. Chronicity of HIV infection leads to several disorders as fever, chronic stress, weight loss and cachexia which are the cause of hypogonadotropic hypogonadism. On the other hand, abnormal secretion of cytokines, secondary to the infection may alter the Leydig cells causing a hypergonadotropic hypogonadism and disrupts steroidogenesis. Cases of testicular invasion by lymphoma or Kaposi's syndromes have also been described. The advent of antiretroviral therapy has reduced the prevalence of hypogonadism in patients infected with HIV that is currently about 20%. This prevalence remains about 20%, regardless of the antiretroviral therapy and CD4-T cell count. No study to our knowledge has so far assessed exhaustively the clinical features, biological, therapeutic and paraclinical of hypotestosteronemiae while assessing the level of total serum testosterone, SHBG and serum free testosterone, among HIV infected patients in the European population.
