Pharmacist-Driven Rapid Initiation of Antiretroviral Therapy Decreases Time to Viral Suppression in People With HIV.

Background: Rapid initiation of antiretroviral therapy (rapid ART) improves clinical outcomes in people with HIV and is endorsed by clinical guidelines. However, logistical challenges limit widespread implementation. We describe an innovative rapid ART model led by pharmacists and its impact on clinical outcomes, including time to viral suppression (TVS). Methods: On 1 January 2019, we implemented Pharmacist-Driven Rapid ART (PHARM-D RAPID ART), including rapid ART initiation by pharmacists. Our retrospective cohort study compared TVS, using a Cox proportional hazards model, and clinical outcomes among individuals with a new HIV diagnosis before (1 January 2017 to 31 December 2017) and after (1 January 2019 to 31 December 2019) implementation. Results: A total of 108 individuals were included. TVS was significantly shorter (P < .001) for the PHARM-D RAPID ART group (n = 51) compared with the preimplementation group (n = 57) (median: 30 days and 66 days, respectively). Those in the PHARM-D RAPID ART group were significantly more likely to achieve VS at any given time during the study period (adjusted hazard ratio: 3.47 [95% confidence interval, 2.25-5.33]). A total of 94.1% (48/51) of patients in the PHARM-D RAPID ART group were retained in care at 1 year. With a median follow-up of 2.4 years in the PHARM-D RAPID ART group, 98% remained suppressed at last recorded viral load. Conclusions: A pharmacist-driven model for rapid ART delivery decreases TVS with high rates of retention in care and durable VS. This model could improve clinical outcomes and increase program feasibility and sustainability.

Lactococcus lactis bacteraemia in a patient on probiotic supplementation therapy.

A 59-year-old woman presented with fever and malaise and was found to have Lactococcus lactis bacteraemia. L. lactis infection is rare in humans with few reported cases, with most associated with dairy food product ingestion. The patient reported use of a multistrain over-the-counter probiotic supplement. After isolation of L. lactis from blood culture, the patient was treated empirically with ertapenem and amoxicillin and displayed clinical improvement. She remained well after completion of antibiotic regimen and discontinued probiotic supplementation use. We review the clinical presentation of L. lactis infection including diagnosis, identification and treatment.

Evaluating HIV Viral Rebound Among Persons on Suppressive Antiretroviral Treatment in the Era of "Undetectable Equals Untransmittable (U†=†U)".

BACKGROUND: Studies have demonstrated that persons with HIV (PWH) maintaining viral suppression do not transmit HIV to HIV-negative partners through condomless sex, leading to the "Undetectable = Untransmittable (U = U)" prevention campaign. However, few studies have examined the durability of suppression in the era of U = U. METHODS: This retrospective cohort study was conducted in Providence, Rhode Island. PWH aged ≥18 years with documented viral suppression (defined as at least 1 viral load [VL] <200 copies/mL and no VL ≥200 copies/mL) in 2015 were included in the baseline cohort. Primary outcomes were viral suppression, viral rebound (at least 1 VL ≥200 copies/mL), or gap in VL monitoring assessed annually from 2016 to 2019. Those with viral rebound were assessed for resuppression within 6 months. Demographic and clinical characteristics associated with viral rebound or gaps in VL monitoring were investigated by bivariate analysis and logistic regression. RESULTS: A total of 1242 patients with viral suppression were included in the baseline cohort. In each follow-up year, 85%-90% maintained viral suppression, 2%-5% experienced viral rebound, and 8%-10% had a gap in VL monitoring. Among those with viral rebound, approximately one-half were suppressed again within 6 months. In the logistic regression models, retention in care was significantly associated with viral suppression, while younger age, black race, high school or equivalent education, non-men who have sex with men, and history of incarceration were significantly associated with viral rebound. CONCLUSIONS: In the U = U era, most patients with viral suppression who are retained in care are likely to maintain viral suppression over time. Some patients require additional support for regular VL monitoring.

Remdesivir Use Compared With Supportive Care in Hospitalized Patients With Severe COVID-19: A Single-Center Experience.

BACKGROUND: The US Food and Drug Administration issued an Emergency Use Authorization for remdesivir use in patients with severe COVID-19. METHODS: We utilized data from 2 quaternary acute care hospitals. The outcomes of interest were the impact of remdesivir on in-hospital death by day 28 and time to recovery, clinical improvement, and discharge. We utilized Cox proportional hazards models and stratified log-rank tests. RESULTS: Two hundred twenty-four patients were included in the study. The median age was 59 years; 67.0% were male; 17/125 patients (13.6%) who received supportive care and 7/99 patients (7.1%) who received remdesivir died. The unadjusted risk for 28-day in-hospital death was lower for patients who received remdesivir compared with patients who received supportive care (hazard ratio [HR], 0.42; 95% CI, 0.16-1.08). Although this trend remained the same after adjusting for age, sex, race, and oxygen requirements on admission (adjusted HR [aHR], 0.49; 95% CI, 0.19-1.28), as well as chronic comorbidities and use of corticosteroids (aHR, 0.44; 95% CI, 0.16-1.23), it did not reach statistical significance. The use of remdesivir was not associated with an increased risk of acute kidney injury (AKI) or liver test abnormalities. Although not statistically significant, the rate ratios for time to recovery, clinical improvement, and discharge were higher in women and black or African American patients. CONCLUSIONS: Patients on remdesivir had lower, albeit not significant, all-cause in-hospital mortality, and the use of remdesivir did not increase the risk for AKI. Promising signals from this study need to be confirmed by future placebo-controlled randomized clinical trials.

An Update on Meningococcal Vaccination.

Neisseria meningitidis bacterial infection can cause severe life-threatening meningitis. Individuals who survive may be left with profound sequelae. In epidemic regions such as the meningitis belt of Africa, the case rate is drastically higher than in nonepidemic regions and is due to distinct outbreak serogroups. Two highly effective conjugate meningococcal vaccine against serogroups A, C, W and Y are licensed and indicated for prevention in childhood vaccination schedules and for travelers to outbreak regions. In the US, meningococcus serogroup B is the main cause of outbreaks, in areas with crowding such as college dorms. It has taken over 40 years to develop a meningitis type B vaccine and now there are 2 brands available for children and teens. All college-bound individuals should complete schedules of both conjugate ACWY serotypes and meningitis B vaccine series. This paper reviews details on who to vaccinate and how to use the currently available meningococcal meningitis vaccines.

SARS-CoV-2 and HIV coinfection: clinical experience from Rhode Island, United States.

INTRODUCTION: Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) has infected >6 million people worldwide since December 2019. Global reports of HIV/SARS-CoV-2 coinfection are limited. To better understand the impact of the coronavirus disease 2019 (COVID-19) pandemic on persons with HIV and improve their care, we present an outpatient and inpatient clinical experience of HIV/SARS-CoV-2 coinfection from Rhode Island, US. METHODS: We describe outpatient and inpatient preparedness for the COVID-19 pandemic, and present a case series of all known patients with HIV/SARS-CoV-2 coinfection at The Miriam Hospital and Rhode Island Hospital, and The Miriam Hospital Infectious Diseases and Immunology Center, in Providence, Rhode Island, US. RESULTS AND DISCUSSION: The Infectious Diseases and Immunology Center rapidly prepared for outpatient and inpatient care of persons with HIV and SARS-CoV-2. Between 30 March and 20 May 2020, 27 patients with HIV were diagnosed with SARS-CoV-2. Twenty were male, six female and one transgender female; average age was 49 years; 13/27 were Hispanic and 6/27 were African American. All had HIV viral load <200 copies/mL and were on antiretroviral therapy with CD4 count range 87 to 1441 cells/µL. Twenty-six of the 27 had common COVID-19 symptoms for one to twenty-eight days and most had other co-morbidities and/or risk factors. Nine of the 27 were hospitalized for one to thirteen days; of those, three lived in a nursing home, six received remdesivir through a clinical trial or emergency use authorization and tolerated it well; eight recovered and one died. Overall, 17% of known Center people had HIV/SARS-CoV-2 coinfection, whereas the comparable state-wide prevalence was 9%. CONCLUSIONS: We highlight challenges of outpatient and inpatient HIV care in the setting of the COVID-19 pandemic and present the largest detailed case series to date from the United States on HIV/SARS-CoV-2 coinfection, adding to limited global reports. The aggregated clinical findings suggest that the clinical presentation and outcomes of COVID-19 appear consistent with those without HIV. Whether SARS-CoV-2 infection is more frequent among persons with HIV remains to be determined. More data are needed as we develop our understanding of how HIV and antiretroviral therapy are affected by or have an impact on this pandemic.

Care of Critically Ill Patients with Human Immunodeficiency Virus.

Care of patients with human immunodeficiency virus (HIV) infection in the intensive care unit (ICU) has changed dramatically since the infection was first recognized in the United States in 1981. The purpose of this review is to describe the current important aspects of care of patients with HIV infection in the ICU, with a primary focus on the United States and developed countries. The epidemiology and initial approach to diagnosis and treatment of HIV (including the newest antiretroviral guidelines), common syndromes and their management in the ICU, and typical comorbidities and opportunistic infections of patients with HIV infection are discussed.

Successful Kidney Transplantation in a Recipient Coinfected with Hepatitis C Genotype 2 and HIV from a Donor Infected with Hepatitis C Genotype 1 in the Direct-Acting Antiviral Era.

Despite significant advances in transplantation of HIV-infected individuals, little is known about HIV coinfected patients with hepatitis C virus (HCV) genotypes other than genotype 1, especially when receiving HCV-infected organs with a different genotype. We describe the first case of kidney transplantation in a man coinfected with hepatitis C and HIV in our state. To our knowledge, this is also the first report of an HIV/HCV/HBV tri-infected patient with non-1 (2a) HCV genotype who received an HCV-infected kidney graft with the discordant genotype (1a), to which he converted after transplant. Our case study highlights the following: (1) transplant centers need to monitor wait times for an HCV-infected organ and regularly assess the risk of delaying HCV antiviral treatment for HCV-infected transplant candidates in anticipation of the transplant from an HCV-infected donor; (2) closer monitoring of tacrolimus levels during the early phases of anti-HCV protease inhibitor introduction and discontinuation may be indicated; (3) donor genotype transmission can occur; (4) HIV/HCV coinfected transplant candidates require a holistic approach with emphasis on the cardiovascular risk profile and low threshold for cardiac catheterization as part of their pretransplant evaluation.

A Nearly 50% Decrease in New HIV Diagnoses in Rhode Island from 2006-2016: Implications for Policy Development and Prevention.

In the last decade, reductions in HIV incidence have been observed across the United States. However, HIV continues to disproportionately impact gay, bisexual, and other men who have sex with men (MSM). In Rhode Island, rates of HIV diagnoses have decreased by 44% across all groups over the last decade. This success has been the result of close collaboration across multiple sectors. Different prevention approaches, including syringe exchange programs, community-based HIV testing, condom distribution, HIV care and treatment, and pre-exposure prophylaxis (PrEP) have all contributed to the decline in HIV diagnoses across the state. In 2015, Rhode Island became one of the first states to sign on to the Joint United Nations Programme on HIV/AIDS "90-90-90" campaign to end the HIV epidemic by 2030. Intensified and innovative initiatives are needed to improve progress in HIV prevention and treatment, especially in populations who are most at risk.

Training medical students in the social determinants of health: the Health Scholars Program at Puentes de Salud.

PURPOSE: Given the large influence of social conditions on health, physicians may be more effective if they are trained to identify and address social factors that impact health. Despite increasing interest in teaching the social determinants of health in undergraduate medical education, few models exist. PARTICIPANTS AND METHODS: We present a 9-month pilot course on the social determinants of health for medical and other health professional students, which is based at Puentes de Salud, Philadelphia, PA, USA, a community health center serving a Latino immigrant population. This service-learning course, called the Health Scholars Program (HSP), was developed and implemented by volunteer medical and public health faculty in partnership with the community-based clinic. The HSP curriculum combines didactic instruction with service experiences at Puentes de Salud and opportunities for critical reflection. The HSP curriculum also includes a longitudinal project where students develop, implement, and evaluate an intervention to address a community-defined need. RESULTS: In our quantitative evaluation, students reported high levels of agreement with the HSP meeting stated course goals, including developing an understanding of the social determinants of health and working effectively with peers to implement community-based projects. Qualitative assessments revealed students' perception of learning more about this topic in the HSP than in their formal medical training and of developing a long-term desire to serve vulnerable communities as a result. CONCLUSION: Our experience with the HSP suggests that partnerships between academic medical centers and community-based organizations can create a feasible, effective, and sustainable platform for teaching medical students about the social determinants of health. Similar medical education programs in the future should seek to achieve a larger scale and to evaluate both students' educational experiences and community-defined outcomes.

Molecular Diagnosis of TB in the HIV Positive Population.

BACKGROUND: Tuberculosis (TB) remains a major contributor to morbidity and mortality in HIV-positive individuals, causing 1.1 million incident cases and 0.32 million deaths in 2012. Diagnosis of TB is particularly challenging in HIV-coinfected individuals, due to a high frequency of smear-negative disease, atypical presentations, and extrapulmonary TB. OBJECTIVE: The aim of this article was to review the current literature on molecular diagnostics for TB with an emphasis on the performance of these diagnostic tests in the HIV-positive population. METHODS: We searched the PubMed database using at least one of the terms TB, HIV, diagnostics, Xpert MTB/RIF, nucleic acid amplification tests, drug susceptibility testing, RNA transcription, and drew on World Health Organization publications. FINDINGS: With increased focus on reducing TB prevalence worldwide, a new set of tools for diagnosing the disease have emerged. Molecular tools such as Xpert MTB/RIF and line-probe assays are now in use or are being rolled out in many regions. The diagnostic performance of these and other molecular assays are discussed here as they pertain to the HIV-positive population. CONCLUSIONS: Molecular diagnostics offer a useful addition and at times, alternative, to traditional culture methods for the diagnosis of TB. However, most of these tests suffer from decreased accuracy in the HIV-positive population.

Vaccinating HIV patients: focus on human papillomavirus and herpes zoster vaccines.

Vaccination has been one of our most powerful tools to decrease morbidity and mortality from infectious diseases in the last century. It is critical to understand the evolving safety and efficacy data for vaccines in HIV-infected individuals as the number of people living with HIV in the United States and globally continues to increase. The quadrivalent human papillomavirus vaccine and the herpes zoster vaccine are newly licensed in the general population, and several studies have recently been published on the safety and efficacy of these vaccines in HIV populations. This manuscript reviews recent data for the vaccines most commonly administered in HIV patients and incorporates these data into our body of knowledge about the safety and efficacy of vaccines in this population. In addition, patient factors that predict response for each vaccine are discussed. Given the great burden of human papillomavirus and herpes zoster in HIV patients, we discuss the benefits and the challenges of vaccinating HIV patients with the human papillomavirus and herpes zoster vaccines. This review provides information that clinicians need to make real-time decisions in the absence of large-scale trials in the HIV population.

Improving the diagnosis of tuberculosis: From QuantiFERON to new techniques to diagnose tuberculosis infections.

The diagnosis of latent and active tuberculosis in the HIV-positive population is challenged by diminished sensitivity of conventional tests, atypical presentations, and the lack of culture methods in the developing world, where the burden of co-infection is greatest. In response to these challenges, a variety of new diagnostics have emerged. These include interferon-gamma release assays for the diagnosis of latent tuberculosis (TB) infection and novel culture methods and molecular assays for the diagnosis of active tuberculosis. Although some tests (such as interferon-gamma release assays) are not clearly superior to existing diagnostics, other novel diagnostics, such as real-time polymerase chain reaction and the microscopic observed direct susceptibility assay hold much promise for prompt and accurate TB diagnosis in this population. Line-probe, nitrate reductase, and mycobacteriophage assays have also provided rapid alternatives to conventional time-consuming drug susceptibility testing and are critical to curtailing the spread of multidrug-resistant TB.
