Despite the fact that tuberculosis (TB) is a curable disease, it still results in approximately 1.8 million deaths annually. Various inadequacies in the current TB treatment strategies are major contributors to this high disease prevalence, including the long duration of therapy, the severe side effects associated with TB drugs, treatment failure due to drug resistance, post-treatment disease relapse, and HIV co-infection. In this review, we describe how metabolomics has contributed toward better explaining/elucidating the mechanisms of drug action/metabolism, drug toxicity and microbial drug resistance, and how metabolite biomarkers may serve as prognostic indicators for predicting treatment outcome as well as for the development of new TB drugs...

Integrase strand transfer inhibitors (INSTIs) are the preferred third agent in first-line antiretroviral therapies. Raltegravir (RAL) was the first INSTI to be approved and used in naïve and experienced patients. Due to its good tolerability and low side effects, RAL has been largely used also in hepatitis co-infected patients. Many years of experience in RAL use now allow literature evidence to be gathered on its safety in HIV/HCV-co-infected patients pre, during and post direct acting agents (DAA) treatment, at all possible stages...

To be effective, HIV programmes should be responsive to the unique needs of diverse groups of infected adolescents. We highlight a range of adolescent perspectives on HIV services, including those who acquired HIV perinatally or sexually and those who were either in care, had dropped out of care, or had never enrolled in care. We conducted semi-structured interviews with 29 adolescents (aged 15-19) and 14 caregivers in western Kenya. Data were analysed using a descriptive analytical approach. Adolescents who were successfully linked had a supportive adult present during diagnosis; tested during hospitalisation or treatment for a recurrent or severe illness; and initiated treatment soon after diagnosis...

BACKGROUND: Raltegravir (RAL) is considered one of the better-tolerated antiretroviral medications, due to limited side effects and minimal drug-drug interactions. Matherials and Methods: We retrospectively evaluated 96 HIV+, over 60 years old, experienced patients who had switched from any antiretroviral drug to raltegravir-based nuc-sparing or standard nucleoside-backbone regimens. RESULTS: The median age of the patients was 66 years (IQR 10.5) (77 M, 19 F); the median time horizon of follow-up was 4 years (IQR 5)...

BACKGROUND: Clinicians are incorporating patient-reported outcomes in the management of HIV-infected persons co-infected with hepatitis C virus (HCV), but there are no validated inventories to monitor symptoms of patients during HCV therapy. DESIGN: Five-year retrospective cohort analysis of persons living with HIV (PLWH) treated for HCV. METHODS: The HCV symptom-inventory (HCV-SI) was administered before, during, and after HCV treatment. Discriminant validity was assessed, separately, in mixed model linear regression of HCV-SI T-scores on treatment regimens (pegylated-interferon and ribavirin; pegylated-interferon, ribavirin, and telaprevir; and interferon-free antivirals); and side effect-related premature treatment discontinuation (SE-DC)...

BACKGROUND: The main approach to treat HIV-1 infection is combination antiretroviral therapy (cART). Although cART is effective in reducing HIV-1 viral load and controlling disease progression, it has many side effects, and is expensive for HIV-1 infected patients who must remain on lifetime treatment. HIV-1 gene therapy has drawn much attention as studies of genome editing tools have progressed. For example, zinc finger nucleases (ZFN), transcription activator like effector nucleases (TALEN) and clustered regularly interspaced short palindromic repeats (CRISPR)-Cas9 have been utilized to successfully disrupt the HIV-1 co-receptors CCR5 or CXCR4, thereby restricting HIV-1 infection...

PURPOSE: Both hormone therapy (HT) and antiretroviral therapy (ART) can be lifesaving for transgender women (TW) living with HIV, but each has side effects and potential drug-drug interactions (DDI). We assessed how concerns about HT-ART interactions affect treatment adherence. METHODS: This study used a cross-sectional survey of TW (n = 87) in Los Angeles, CA. RESULTS: Fifty-four percent were living with HIV; 64% used HT. Only 49% of TW living with HIV discussed ART-HT DDI with their provider; 40% reported not taking ART (12%), HT (12%), or both (16%) as directed due to DDI concerns...

Combination antiretroviral therapy (cART) is currently the most effective treatment for HIV-1 infection. HIV-1 protease inhibitors (PIs) are an important component of some regimens of cART. However, PIs are known for sub-optimal ADME properties, resulting in poor oral bioavailability. This often necessitates high drug doses, combination with pharmacokinetic enhancers and/or special formulations in order to effectively deliver PIs, which may lead to a high pill burden and reduced patient compliance. As a remedy, improving the ADME properties of existing drugs via prodrug and other approaches has been pursued in addition to the development of next generation PIs with improved pharmacokinetic, resistance and side effect profiles...

OBJECTIVES: Men who have sex with men (MSM) living with HIV are at high risk for anal high-grade squamous intraepithelial lesions (HSILs) and cancer. The best management of anal HSIL remains unclear. Our objective was to assess whether argon plasma coagulation (APC) could be safe, well tolerated and efficient to treat anal HSILs in MSM living with HIV. METHODS: A prospective phase II, open-label, pilot study was conducted to evaluate APC to treat anal HSILs in 20 HIV-positive MSM...

Previous research has demonstrated increased comorbidities related to the chronic effects of HIV. Rehabilitation science offers a useful approach for studying chronic illness. This longitudinal qualitative study used a rehabilitation science approach to explore the experiences over time of women and men living with HIV and on antiretroviral therapy (ART) in the high HIV-prevalence setting of Lusaka, Zambia. Thirty-five participants participated in a total of 99 in-depth interviews from 2012 to 2015. The central pattern that emerged across the participants' narratives was the paradoxical experience of profound optimism alongside significant new challenges...

INTRODUCTION: While the rapid expansion in antiretroviral therapy access in low and middle income countries has resulted in dramatic declines in mortality rates, many people living with HIV face new or worsening experiences of disability. As nearly 1 in 20 adults are living with HIV in sub-Saharan Africa-many of whom are likely to develop disabling sequelae from long-term infection, co-morbidities and side effects of their treatment-understanding the availability and accessibility of services to address HIV-related disabilities is of vital importance...

Combination antiretroviral treatment (cART) has significantly improved the life expectancy of people living with HIV. The life-long nature of cART increases the risk of side effects, which in some cases may have been caused by specific genetic characteristics. Patients treated with atazanavir (ATV) boosted with ritonavir (rit), which is a protease inhibitor used for the treatment of HIV, present with elevated bilirubin levels, at high proportions. ATV/rit-related hyperbilirubinemia has been previously associated with genetic characteristics in uridine diphosphate glucuronosyltransferase (UGT) enzyme...

Neurocognitive impairment (NCI) is an increasingly important comorbidity in an ageing HIV+ population. Despite the lack of available treatment modalities, screening for NCI is recommended. In the UMC Utrecht, yearly NCI screening is done using the Montreal Cognitive Assessment (MoCA) tool and the HIV Dementia Scale (HDS). The aim of this study was to evaluate this screening protocol in relation to clinical outcomes and management. A retrospective cohort study was performed in suppressed adult HIV+ patients...

With the progressive increase in life expectancy of HIV-positive patient, thanks to "highly active antiretroviral therapy" (HAART), new comorbidities, and especially cardiovascular diseases (CVDs) are emerging as an important concern. An increased risk of coronary artery disease, often in a younger age, has been observed in this population. The underlying pathophysiology is complex and partially still unclear, with the interaction of viral infection-and systemic inflammation-antiretroviral therapy and traditional risk factors...

HIV infection continues to be a life-long chronic disease in spite of the success of antiretroviral therapy (ART) in controlling viral replication and preventing disease progression. However, because of the high cost of treatment, severe side effects, and inefficiency in curing the disease with ART, there is a call for alternative therapies that will provide a functional cure for HIV. Cytotoxic T lymphocytes (CTLs) are vital in the control and clearance of viral infections and therefore immune-based therapies have attempted to engineer HIV-specific CTLs that would be able to clear the infection from the body...
