Background:  Tuberculous meningitis (TBM) is the most severe form of tuberculosis. Co-infection with HIV increases the risk of developing TBM, complicates treatment, and substantially worsens outcome. Whether corticosteroids confer a survival benefit in HIV-infected patients with TBM remains uncertain. Hepatitis is the most common drug-induced serious adverse event associated with anti-tuberculosis treatment, occurring in 20% of HIV-infected patients. The suggested concentration thresholds for stopping anti-tuberculosis drugs are not evidence-based...

The management of patients with human immunodeficiency virus (HIV) can be a complicated specialty within itself, made even more complex when there are so many unanswered questions regarding the care of critically ill patients with HIV. The lack of consensus on the use of antiretroviral medications in the critically ill patient population has contributed to an ongoing clinical debate among intensivists. This review focuses on the pharmacological complications of antiretroviral therapy (ART) in the intensive care setting, specifically the initiation of ART in patients newly diagnosed with HIV, immune reconstitution inflammatory syndrome (IRIS), continuation of ART in those who were on a complete regimen prior to intensive care unit admission, barriers of drug delivery alternatives, and drug-drug interactions...

BACKGROUND: Studies from sub-Saharan Africa (SSA) document how barriers to ART adherence present additional complications among adolescents and young adults living with HIV. We qualitatively explored barriers to ART adherence in Uganda among individuals age 14-24 to understand the unique challenges faced by this age group. METHODS: We conducted focus group (FG) discussions with Community Advisory Board members (n = 1), health care providers (n = 2), and male and female groups of adolescents age 14-17 (n = 2) and youth age 18-24 (n = 2) in Kampala, Uganda...

PURPOSE OF REVIEW: The detrimental synergy of colliding HIV and tuberculosis (TB) epidemics is most devastating among children and adolescents living with HIV (CALWH) who shoulder a disproportionate burden of all child TB mortality. RECENT FINDINGS: CALWH benefit less from Bacille-Calmette Guerin vaccination than HIV-uninfected children and are not receiving TB preventive therapy despite global recommendations. Further, the predictive utility of most diagnostic tools is reduced in CALWH...

PURPOSE: Penile implants or nodules are objects inserted beneath the skin of the penis mostly for erotic purposes. The procedure is painful and there may be complications. It is often associated with prison. Our objectives were to describe the prevalence of penile nodules among inmates in French Guiana, and to study factors associated with this practice, notably psychiatric diagnoses. METHODS: The study was cross-sectional. All consenting new adult prisoners incarcerated between 01/01/2014 and 31/12/2014 at the penitentiary centre of French Guiana were included...

Rhabdomyolysis is characterized by muscle necrosis and leakage of toxic intracellular contents into the circulatory system. It is most commonly caused by trauma, physical exertion, drugs, toxins, and a variety of infections; only rarely is it associated with acute human immunodeficiency virus (HIV) infection alone. The severity of illness ranges from asymptomatic elevations in serum muscle enzymes to life-threatening electrolyte imbalances and acute kidney injury. High HIV viral load is associated with higher muscle breakdown that increases the incidence of severe acute kidney injury and sometimes the need for renal replacement therapy...

Human immunodeficiency virus (HIV) pre-exposure prophylaxis (PrEP) strategies with proven in vivo efficacy rely on antiretroviral drugs, creating the potential for drug resistance and complicated treatment options in individuals who become infected. Moreover, on-demand products are currently missing from the PrEP development portfolio. Griffithsin (GRFT) is a non-antiretroviral HIV entry inhibitor derived from red algae with an excellent safety profile and potent activity in vitro. When combined with carrageenan (CG), GRFT has strong activity against herpes simplex virus-2 (HSV-2) and human papillomavirus (HPV) in vitro and in vivo...

: Improved survival among HIV-1 infected individuals with the advent of antiretroviral therapy has clearly led to a greater prevalence of non-infectious complications. One of the most devastating sequelae in these individuals is the development of pulmonary arterial hypertension (PAH). Various epidemiological studies suggest a worse survival of HIV-PAH patients when compared to other forms of PAH. Given that only a subset and not all HIV-infected individuals develop HIV-PAH, suggests that an additional second hit of genetic or environmental triggers is needed for the development of PAH...

Here we review how immune activation and insulin resistance contribute to the metabolic alterations observed in HIV-infected patients, and how these alterations increase the risk of developing CVD. The introduction and evolution of antiretroviral drugs over the past 25 years has completely changed the clinical prognosis of HIV-infected patients. The deaths of these individuals are now related to atherosclerotic CVDs, rather than from the viral infection itself. However, HIV infection, cART, and intestinal microbiota are associated with immune activation and insulin resistance, which can lead to the development of a variety of diseases and disorders, especially with regards to CVDs...

Antiretroviral (ART) drugs has previously been associated with lipodystrophic syndrome, metabolic consequences, and neuropsychiatric complications. ART drugs include three main classes of protease inhibitors (PIs), nucleoside analog reverse transcriptase inhibitors (NRTIs), and non-nucleoside reverse transcriptase inhibitors (NNRTIs). Our previous work demonstrated that a high risk of hyperlipidemia was observed in HIV-1-infected patients who received ART drugs in Taiwan. Patients receiving ART drugs containing either Abacavir/Lamivudine (Aba/Lam; NRTI/NRTI), Lamivudine/Zidovudine (Lam/Zido; NRTI/NRTI), or Lopinavir/Ritonavir (Lop/Rit; PI) have the highest risk of hyperlipidemia...

BACKGROUND: Active illicit drug use can present a barrier to the medical management of HIV infection by complicating adherence to antiretroviral therapy (ART). Plasma HIV-1 RNA viral load (VL) rebound, defined as a period of detectable HIV viral load (VL) following antiretroviral therapy (ART) and VL suppression, can lead to the generation of viral resistance and potential treatment failure. We sought to investigate the contribution of substance use patterns on rates of VL rebound. METHODS: We used data from the ACCESS study, a long-running community-recruited prospective cohort of HIV-positive people who use illicit drugs in Vancouver, Canada, a setting of universal no-cost HIV treatment...

BACKGROUND: People with HIV infection in the United States are often affected by chronic viral hepatitis. These coinfected people with either HBV or HCV are at increased risk for serious, life-threatening complications. Coinfections with viral hepatitis may also complicate the delivery of anti-retroviral therapy (ART) by escalating the risk of drug-related hepatoxicity. According to the Centers for Disease Control and Prevention (CDC), approximately 10 percent of people with HIV in the United States also have HBV, and 25 percent also have HCV coinfection...

PURPOSE: As a result of multilateral migration and globalization in times of humanitarian crises, western countries face a possible increase in the incidence of central nervous system tuberculosis (CNS TB). The diagnosis of CNS TB is challenging and often delayed due to the manifold and often non-specific presentation of the disease. The aim of this review is to analyze and summarize imaging features and correlated clinical findings of CNS TB. METHODS: The different manifestations of CNS TB are explained and illustrated by characteristic neuroradiological as well as neuropathological findings...

Background: Successful implementation of gene therapy heavily relies on efficiently delivering genetic materials and specific targeting into cells. Oncogene-driven endocytosis stimulates nutrient uptake and also develops an endocytosis-mediated defense against therapeutic agents. Cell-penetrating peptides, typically HIV-Tat, are well known for efficient delivery of nucleic acid drugs but lack targeting specificity. Various passive targeting strategies were pursued to enhance the tumor targeting efficiency; however, they are still limited by complicated cellular endocytosis routes and the heterogeneity of cancer types...

FDA approved oral daily tenofovir/emtricitabine (TruvadaTM ) for pre-exposure prophylaxis of HIV infection in 2012 on the basis of two randomized controlled trials, one in men who have sex with men (MSM) and another in HIV serodiscordant heterosexual couples. Subsequently, even greater efficacy has been demonstrated in MSM with rapid, population level incidence reductions in some locations. In contrast, studies of antiretroviral PrEP in heterosexual women showed only modest or no efficacy, largely attributed to low adherence...

BACKGROUND: Smuggling of illegal drugs by hiding them inside one's own body, also called body packing, is a worldwide phenomenon. Cocaine is the most frequently transported drug. Body packing is a potentially lethal practice. The most serious complications of body packing are gastrointestinal obstruction or perforation and drug toxicity due to packet leakage or rupture. CASE PRESENTATION: A 30-year-old confirmed body packer was brought to our emergency department from jail because of agitation and mydriasis...

Tuberculosis (TB) is a major global health burden. The emergence of the human immunodeficiency virus (HIV) epidemic and drug resistance has complicated global TB control. Pulmonary delivery of drugs using dry powder inhalers (DPI) is an emerging approach to treat TB. In comparison with the conventional pulmonary delivery for asthma and chronic obstructive pulmonary disease (COPD), TB requires high dose delivery to the lung. However, high dose delivery depends on the successful design of the inhaler device and the formulation of highly aerosolizable powders...

BACKGROUND: As countries scale up antiretroviral therapy (ART) for children, innovative strategies to deliver quality services to children are needed. Differentiated ART delivery models have been successful in adults, but no such program has been described in children. We describe the Standardized Pediatric Expedited Encounters for ART Drugs Initiative (SPEEDI). METHODS: Descriptive analysis of patients eligible for SPEEDI was done via retrospective review of children, adolescents, and young adults on ART at the Baylor Centre of Excellence (COE) in Mbeya, Tanzania between January 2013 and December 2015...
