Improved Virologic Suppression With HIV Subspecialty Care in a Large Prison System Using Telemedicine: An Observational Study With Historical Controls

Correctional populations have an elevated human immunodeficiency virus (HIV) prevalence, yet many individuals lack access to subspecialty care. Our study showed that HIV-infected inmates had significantly greater virologic suppression and higher CD4 T-lymphocyte counts when managed by a multidisciplinary team of subspecialists conducting clinics via telemedicine. In other studies, these outcomes have been associated with reductions on HIV-related morbidity and mortality, as well as HIV transmission.

Clinical utility of dronabinol in the treatment of weight loss associated with HIV and AIDS

Since the beginning of the HIV/AIDS epidemic, weight loss has been a common complaint for patients. The use of various definitions defining HIV wasting syndrome has made it difficult to determine its actual prevalence. Despite the use of highly active antiretroviral therapy, it is estimated that the prevalence of HIV wasting syndrome is between 14% and 38%. HIV wasting syndrome may stem from conditions affecting chewing, swallowing, or gastrointestinal motility, neurologic disease affecting food intake or the perception of hunger or ability to eat, psychiatric illness, food insecurity generated from psychosocial or economic concerns, or anorexia due to medications, malabsorption, infections, or tumors. Treatment of HIV wasting syndrome may be managed with appetite stimulants (megestrol acetate or dronabinol), anabolic agents (testosterone, testosterone analogs, or recombinant human growth hormone), or, rarely, cytokine production modulators (thalidomide). The goal of this review is to provide an in-depth evaluation based on existing clinical trials on the clinical utility of dronabinol in the treatment of weight loss associated with HIV/AIDS. Although total body weight gain varies with dronabinol use (–2.0 to 3.2 kg), dronabinol is a well-tolerated option to promote appetite stimulation. Further studies are needed with standardized definitions of HIV-associated weight loss and clinical outcomes, robust sample sizes, safety and efficacy data on chronic use of dronabinol beyond 52 weeks, and associated virologic and immunologic outcomes.

Pharmacologic Management of Human Immunodeficiency Virus Wasting Syndrome

Pharmacologic interventions for human immunodeficiency virus (HIV) wasting have been studied since the 1990s, but the results of these interventions have been difficult to compare because the studies used different HIV wasting definitions and assessed various patient outcomes. Thus, we performed a systematic review of the current literature to identify studies that evaluated pharmacologic management of HIV wasting and to compare and contrast treatment options. Further, we provide a comprehensive review of these treatment options and describe the definition of HIV wasting used in each study, the outcomes assessed, and whether antiretroviral therapy was used during the HIV wasting treatment. Literature searches of the PubMed/Medline (1946–2014) and Google Scholar databases were performed, and a review of the bibliographies of retrieved articles was performed to identify additional references. Only English‐language articles pertaining to humans and HIV‐infected individuals were evaluated. Thirty‐six studies were identified that assessed pharmacologic interventions to treat HIV wasting. Appetite stimulants, such as megestrol acetate, have been shown to increase total body weight (TBW) and body mass index in HIV‐infected patients with wasting. Studies evaluating dronabinol showed conflicting data on TBW increases, but the drug may have minimal benefit on body composition compared with other appetite stimulants. Testosterone has been shown to be effective in HIV wasting for those who suffer from hypogonadism. Recombinant human growth hormone has been evaluated for HIV wasting and has shown promising results for TBW and lean body mass increases. Thalidomide has been studied; however, its use is limited due to its toxicities. Although megestrol acetate and dronabinol are approved by the U.S. Food and Drug Administration (FDA) for the treatment of HIV wasting, it is important to recognize other comorbidities such as depression or hypogonadism that may contribute to the patients appetite and weight loss. If a patient is diagnosed with hypogonadism and HIV wasting, testosterone would be a good therapeutic option. Although mirtazapine is not FDA approved for the management of HIV wasting, it has been shown to promote weight gain while treating depression symptoms. Mirtazapine may be a promising pharmacologic option in the management of HIV wasting and depression, but further research is needed.

Strength in Amalgamation: Newer Combination Agents for HIV and Implications for Practice

Antiretroviral (ART) therapy for the treatment of human immunodeficiency virus (HIV) infection has undergone significant changes over the past 30 years. Many single‐tablet regimens (STRs), including newer fixed‐dose combination (FDC) tablets, are available, offering patients several options for choosing a treatment regimen that works best for them. Given these changes, patients are more likely to adhere to treatment, achieve better clinical outcomes, and experience both fewer side effects and drug‐drug interactions. Newer STRs include dolutegravir (DTG)/lamivudine (3TC)/abacavir (ABC) (Triumeq; Viiv Healthcare, Research Triangle Park, NC), rilpivirine (RPV)/emtricitabine (FTC)/tenofovir alafenamide (TAF) (Odefsey; Gilead, Foster City, CA), RPV/FTC/tenofovir disoproxil fumarate (TDF) (Complera; Gilead), elvitegravir (EVG)/cobicistat (COBI)/FTC/TDF (Stribild; Gilead), and EVG/COBI/FTC/TAF (Genvoya; Gilead). Recently approved FDCs, such as atazanavir (ATV)/COBI (Evotaz; Bristol‐Myers Squibb, Princeton, NJ), darunavir (DRV)/COBI (Prezcobix; Janssen Products, Titusville NJ), and FTC/TAF (Descovy; Gilead), are also now available. The Department of Health and Human Services treatment guidelines for HIV recommend many of these integrase strand transfer inhibitor (INSTI) STRs as a preferred choice for initiation of treatment in both ART‐naive and ‐experienced patients because they offer comparably faster rates of virologic suppression, reduced rates of resistance development (especially with DTG), and overall better adherence than protease inhibitors or NNRTIs. Numerous phase 3 clinical trials support these recommendations including several switch or simplification clinical trials. Notably, the novel pharmacokinetic booster COBI, with its water soluble properties, has enabled the development and coformulation of a few of these STRs and FDCs. Also, a newer tenofovir salt formulation, TAF, has an advantageous pharmacokinetic profile, contributing to better overall renal and bone tolerability compared with TDF. Further simplification regimens comprising dual ART therapies are currently being explored. This review provides an overview of the clinical efficacy and safety data for these coformulated agents, highlighting the relative impact on comparative adverse events, assessing the potential for experiencing fewer drug‐drug interactions, and discussing the clinical implications regarding adherence to treatment.

Acute Care Management of the HIV-Infected Patient: A Report from the HIV Practice and Research Network of the American College of Clinical Pharmacy

Patients infected with human immunodeficiency virus (HIV) admitted to the hospital have complex antiretroviral therapy (ART) regimens with an increased medication error rate upon admission. This report provides a resource for clinicians managing HIV‐infected patients and ART in the inpatient setting.

Telehealth: Increasing Access to High Quality Care by Expanding the Role of Technology in Correctional Medicine

The United States (US) has a large correctional population. However, many incarcerated persons lack access to evidence-based, up-to-date medical care, particularly by subspecialty providers, due to limitations of geography, travel, cost and other resources. The use of telehealth technologies can remove these barriers, increasing access to high quality, multidisciplinary care. Studies have shown that, with telemedicine, timely triage and medical management can be provided across many disciplines, which may lead to improved clinical outcomes and significant cost savings.

A Review of HIV Pre-Exposure Prophylaxis: The Female Perspective

When taken consistently, pre-exposure prophylaxis (PrEP) against human immunodeficiency virus (HIV) with once daily tenofovir disoproxil fumarate-emtricitabine (TDF-FTC) has been shown to safely reduce the incidence of HIV infection in high-risk individuals by more than 90%. Yet, according to the Centers for Disease Control and Prevention, there were about 2.1 million new cases of HIV reported worldwide in 2015. Undoubtedly, there is significant room for improvement to prevent the transmission of HIV. Research to date has been heavily focused on the high-risk men who have sex with men (MSM) population, yet, many women worldwide remain at high risk of HIV transmission. PrEP offers women a protection method that is discrete, does not require partner consent, and may be compatible with both contraception or conception as desired. However, women often remain under-represented in HIV prevention literature and are reported to have lower real-world uptake in comparison to men. Furthermore, clinical trials that do focus on the female population demonstrate mixed efficacy results that highlight the adherence challenges in this population. It is essential to identify factors that contribute to PrEP non-adherence as well as barriers to preventative treatment. This review will discuss the clinical evidence behind PrEP in women, current barriers to use afflicting this population, pharmacotherapy considerations for the female patient, alternative and future agents, and the current real-world application of PrEP.

Immunologic and Virologic Outcomes of Obese and Nonobese Incarcerated Adults on Antiretroviral Therapy for HIV Infection

Background: Obesity is common among patients with HIV. The objective of this study was to characterize response to antiretroviral therapy (ART) in a cohort of obese incarcerated adults compared to a nonobese cohort. Methods: A retrospective matched cohort study was conducted in an HIV telemedicine clinic. Patients with body mass index (BMI) >30 kg/m2 who received the same ART with >95% adherence for at least 6 months were matched to nonobese patients by age, gender, ART, CD4 count, and viral load at baseline. Results: Twenty pairs were included, with an average BMI of 24 kg/m2 in the nonobese cohort and 35 kg/m2 in the obese cohort. No difference was observed in the proportion of patients who achieved virologic suppression or the change in CD4 count from baseline to 6 to 12 months. Conclusion: This study revealed no differences in immunologic recovery or virologic suppression between obese and nonobese patients in an adult correctional population.

Effectiveness of Single- and Multiple-Tablet Antiretroviral Regimens in Correctional Setting for Treatment-Experienced HIV Patients

Minimal information is available regarding antiretroviral prescribing patterns and outcomes for HIV patients in correctional systems. This study analyzes single- (STR) and multiple- (MTR) tablet regimen effectiveness in patients receiving HIV telemedicine care through the Illinois Department of Corrections (IDOC). This study involves a retrospective review of HIV-positive adult patients in IDOC on either an STR (efavirenz, rilpivirine, elvitegravir based) or an MTR (emtricitabine/tenofovir with atazanavir/ritonavir, darunavir/ritonavir, or raltegravir). No significant differences in virologic suppression were seen between groups at baseline, weeks 24, 48, 96, and last clinic visit. Similar proportions of patient-reported adverse effects, self-reported adherence, and discontinuation rates were found in both groups. With similar rates of viral suppression, tolerability, adherence, and discontinuation, administering MTR in the incarcerated population is a viable alternative to STR.

Sustained viral suppression with co-administration of oxcarbazepine and dolutegravir

Co-administration of dolutegravir and oxcarbazepine has been reported to reduce levels of dolutegravir and therefore is contraindicated due to insufficient data to make dosing recommendations. We present eight cases in which patients with human immunodeficiency virus (HIV) inadvertently received oxcarbazepine while concurrently receiving 50 mg of dolutegravir daily as part of their antiretroviral therapy. Upon further evaluation, lab results revealed that despite the risk of decreased levels of dolutegravir due to possible oxcarbazepine enzyme induction, patients maintained at or near virologic suppression (viral load <20 copies/ml). Suppression was maintained in patients virally suppressed prior to oxcarbazepine initiation as well as in patients receiving high doses of oxcarbazepine (>1200 mg). All patients self-reported complete adherence to oxcarbazepine and dolutegravir. Furthermore, careful review of additional patient medications suggested no other identifiable drug interactions that could have affected their antiretroviral therapy. This case series suggests that despite the well-documented drug interaction, concomitant administration of oxcarbazepine and dolutegravir in the clinical setting did not adversely affect viral suppression in patients with HIV.
