RESUMEN
BACKGROUND: Among antiretroviral therapy (ART)-treated people with human immunodeficiency virus (PWH), persistent systemic immune activation contributes to atherogenesis atherosclerotic, cardiovascular disease (CVD) events, and mortality. Factors associated with key immune activation indices have not previously been characterized among a global primary CVD prevention cohort of PWH. METHODS: Leveraging baseline Randomized Trial to Prevent Vascular Events in HIV (REPRIEVE) data, we evaluated factors associated with soluble CD14 (sCD14) and oxidized low-density lipoprotein (oxLDL). RESULTS: The primary analysis cohort included 4907 participants from 5 global-burden-of-disease regions (38% female, 48% Black, median age 50 years). In fully adjusted models for sCD14, female sex and White race (among those in high-income regions) were associated with higher sCD14 levels, while higher body mass index (BMI) and current use of nucleoside reverse transcriptase inhibitorâ +â integrase strand transfer inhibitor ART were associated with lower sCD14 levels. In fully adjusted models for oxLDL, male sex, residence in high-income regions, White race (among those in high-income regions), and higher BMI were associated with higher oxLDL levels. In a subanalysis cohort of 1396 women with HIV, increased reproductive age was associated with higher sCD14 levels but not with higher oxLDL levels. CONCLUSIONS: Factors associated with sCD14 and oxLDL, 2 key indices of immune-mediated CVD risk, differ. Future studies will elucidate ways in which medications (eg, statins) and behavioral modifications influence sCD14 and oxLDL and the extent to which dampening of these markers mediates CVD-protective effects.

In response to the opioid crisis, IDSA and HIVMA established a working group to drive an evidence- and human rights-based response to illicit drug use and associated infectious diseases. Infectious diseases and HIV physicians have an opportunity to intervene, addressing both conditions. IDSA and HIVMA have developed a policy agenda highlighting evidence-based practices that need further dissemination. This paper reviews (1) programs most relevant to infectious diseases in the 2018 SUPPORT Act; (2) opportunities offered by the "End the HIV Epidemic" initiative; and (3) policy changes necessary to affect the trajectory of the opioid epidemic and associated infections. Issues addressed include leveraging harm reduction tools and improving integrated prevention and treatment services for the infectious diseases and substance use disorder care continuum. By strengthening collaborations between infectious diseases and addiction specialists, including increasing training in substance use disorder treatment among infectious diseases and addiction specialists, we can decrease morbidity and mortality associated with these overlapping epidemics.

Persons with opioid use disorder (OUD) hospitalized with severe, injection-related infections (SIRI) are frequently hospitalized for the duration of IV antibiotic treatment due to concerns regarding their eligibility for outpatient parenteral antimicrobial therapy (OPAT), which is the standard of care for prolonged IV antibiotic courses for patients without drug use. As part of a pilot study, a novel, integrated care model was developed where patients with OUD and SIRI receive addiction consultation and buprenorphine induction while hospitalized, followed by ongoing management in an outpatient clinic that combines office-based opioid treatment with buprenorphine pharmacotherapy and counseling services with OPAT. Through three illustrative case vignettes the outpatient model is described along with challenges, lessons learned and future directions.

Alcohol is prevalent among people living with HIV and can lead to multiple comorbid conditions (multimorbidity). The purpose of this study was to examine the relationship between alcohol use history and multimorbidity among people living with HIV. A retrospective cohort study design was conducted at an urban, academic infectious disease clinic in Kentucky. Individuals seeking care between 2010 and 2014 were included. Modified Poisson regression was used to examine the relationship between alcohol use history (never, current, and former use) and multimorbidity (≥ 2 conditions). A total of 949 individuals were included in the study, with 5.1 and 17.6% reporting former and current alcohol use, respectively. Sixty-five percent had ≥ 1 condition and 82.6% of those had ≥ 2 conditions diagnosed. The risk of multimorbidity was 1.70 (95% CI 1.35-2.14) times higher for a current user compared to a never user. Reductions in alcohol use may lead to lower rates of multimorbidity.

The purpose of this study was to understand how the presence of comorbid conditions affects retention in HIV medical care over time. A retrospective cohort design employing a medical chart review was conducted. A generalized linear mixed model was used to determine the predictors that affect retention over time. The mean follow-up for the study population was 5.75 years, and only 48.6 % achieved optimal retention. During the study period, 882 non-HIV related comorbidities were diagnosed in 610 (44.9 %) patients of whom, approximately 31 % had ≥2 comorbidities diagnosed. In the mixed model, the number of comorbidities diagnosed during the study period was associated with improved retention over time (odds ratio = 2.28; 95 % confidence interval = 1.83-2.71). Having a non-HIV related comorbid condition was associated with improved retention, while those patients who were 'healthier' had worse retention. More research is needed to identify factors that improve retention and to quantify the impact of these factors.

OBJECTIVE: To report on invasive aspergillosis infection in an immunocompetent adult after a near-drowning event, which allowed this pathogen to easily gain access to the human respiratory system and result in rapid, severe infection. CASE SUMMARY: A 51-year-old female developed severe pneumonia after a near-drowning accident. Two days after admission, a bronchial alveolar lavage (BAL) was performed and was positive for Aspergillus fumigatus. After a 30-day hospital course, multiple antifungals, and various routes of administration, the patient expired. DISCUSSION:: Pneumonia is particularly common because of the aspiration of contaminated water. Whereas pneumococci, staphylococci, and Gram-negative bacteria are all common pathogens for this type of infection, fungi such as Aspergillus spp can also be involved and may be life threatening. Typically, these cases are reported in individuals with an immunodeficiency such as from receipt of myelosuppressive chemotherapy, bone marrow transplants, or lung transplants. Despite initiation of an appropriate empirical antifungal regimen, the rapid recovery of A fumigatus from pulmonary alveolar lavage and BAL samples as well as extremely elevated levels of galactomannan and (1â3)-ß-D glucan may have indicated an invasive fungal infection (IFI). CONCLUSION:: IFIs are uncommon in immunocompetent adults, but in the event of a near-drowning accident, environmental fungi can gain access to the human respiratory system and result in rapid, severe infection. Based on this case and the others described, it appears that near-drowning patients need an early initial evaluation for IFI.
RESUMEN
When species disperse into previously unoccupied habitats, new populations encounter unfamiliar species interactions such as altered parasite loads. Theory predicts that newly founded populations should exhibit destabilized eco-evolutionary fluctuations in infection rates and immune traits. However, to understand founder effects biologists typically rely on retrospective studies of range expansions, missing early-generation infection dynamics. To remedy this, we experimentally founded whole-lake populations of threespine stickleback. Infection rates were temporally stable in native source lakes. In contrast, newly founded populations exhibit destabilized host-parasite dynamics: high starting infection rates led to increases in a heritable immune trait (peritoneal fibrosis), suppressing infection rates. The resulting temporal auto-correlation between infection and immunity suggest that newly founded populations can exhibit rapid host-parasite eco-evolutionary dynamics.
RESUMEN
Although multidisciplinary teams have been shown to decrease in-hospital mortality for patient with infectious endocarditis, most studies have focused on the inpatient role of these teams, and are primarily based at European tertiary care centers. There is limited literature available on the optimal longitudinal care of this patient population. Here we outline our experience developing an interdisciplinary endocarditis program at the University of Kentucky, which cares for patients from their index hospitalization into the outpatient setting, while also coordinating transfers from regional hospitals and offering education to regional providers.

Protein S (PS), the critical plasma cofactor for the anticoagulants tissue factor (TF) pathway inhibitor (TFPI) and activated protein C (APC), circulates in two functionally distinct pools: free (anticoagulant) or bound to complement component 4b-binding protein (C4BP) (anti-inflammatory). Acquired free PS deficiency is detected in several viral infections, but its cause is unclear. Here, we identified a shear-dependent interaction between PS and von Willebrand Factor (VWF) by mass spectrometry. Consistently, plasma PS and VWF comigrated in both native and agarose gel electrophoresis. The PS/VWF interaction was blocked by TFPI but not APC, suggesting an interaction with the C-terminal sex hormone binding globulin (SHBG) region of PS. Microfluidic systems, mimicking arterial laminar flow or disrupted turbulent flow, demonstrated that PS stably binds VWF as VWF unfolds under turbulent flow. PS/VWF complexes also localized to platelet thrombi under laminar arterial flow. In thrombin generation-based assays, shearing plasma decreased PS activity, an effect not seen in the absence of VWF. Finally, free PS deficiency in COVID-19 patients, measured using an antibody that binds near the C4BP binding site in SHBG, correlated with changes in VWF, but not C4BP, and with thrombin generation. Our data suggest that PS binds to a shear-exposed site on VWF, thus sequestering free PS and decreasing its anticoagulant activity, which would account for the increased thrombin generation potential. As many viral infections present with free PS deficiency, elevated circulating VWF, and increased vascular shear, we propose that the PS/VWF interaction reported here is a likely contributor to virus-associated thrombotic risk.
RESUMEN
The purpose of this study was to compare multiple measures of retention in HIV medical care by determining their ability to predict viral suppression. Patients who sought care between 2003 and 2011 were eligible. Visit constancy, gaps-in-care, and HRSA measure were the measures compared. Multiple logistic regressions and area under the curve statistics were employed to determine which measure most accurately discerned between patients with or without viral suppression. There were 850 patients included in the study. The mean follow-up time among the cohort was 5.6 years and less than half were consistently retained in care. All three measures had similar area under the curves, but only visit constancy and gaps in care were significantly associated with viral suppression. Retention in care should be defined consistently across studies and interventions should be set in place to increase the number of optimal retainers.

The diagnosis of secondary syphilis can be challenging due to its various clinical and histopathological presentations. A late or incorrect diagnosis can result in disease progression with consequent morbidity or mortality. Due to the importance of a correct diagnosis and specific treatment, it is of the utmost importance for healthcare providers to consider the various manifestations of syphilis. We describe an atypical presentation of secondary syphilis in an African American man infected with HIV and chronic psoriasis, who presented with two months of diffuse maculopapular rash and new visual changes, found to have acute syphilitic placoid chorioretinitis (ASPCC) and a psoriasis vulgaris flare.
RESUMEN
Injection-related infections require prolonged antibiotic therapy. Outpatient parenteral antimicrobial therapy (OPAT) has been shown to be feasible for people who inject drugs (PWID) in some settings. We report a national survey on practice patterns and attitudes of infectious diseases clinicians in the United States regarding use of OPAT for PWID.
RESUMEN
Introduction: Long COVID is the overarching name for a wide variety of disorders that may follow the diagnosis of acute SARS-COVID-19 infection and persist for weeks to many months. Nearly every organ system may be affected. Methods: We report nine patients suffering with Long COVID for 101 to 547 days. All exhibited significant perturbations of their immune systems, but only one was known to be immunodeficient prior to the studies directed at evaluating them for possible treatment. Neurological and cardiac symptoms were most common. Based on this data and other evidence suggesting autoimmune reactivity, we planned to treat them for 3 months with long-term high-dose immunoglobulin therapy. If there was evidence of benefit at 3 months, the regimen was continued. Results: The patients' ages ranged from 34 to 79 years-with five male and four female patients, respectively. All nine patients exhibited significant immune perturbations prior to treatment. One patient declined this treatment, and insurance support was not approved for two others. The other six have been treated, and all have had a significant to remarkable clinical benefit. Conclusion: Long-term high-dose immunoglobulin therapy is an effective therapeutic option for treating patients with Long COVID.

Introduction: A marked increase in hospitalizations for severe, injection-related infections (SIRI) has been associated with the opioid epidemic. Outpatient parenteral antibiotic therapy (OPAT) is typically not offered to persons with opioid use disorder (OUD) and SIRI, though increasing evidence suggests it may be feasible and safe. This study evaluates the efficacy and cost-effectiveness of an integrated care model combining Buprenorphine treatment of OUD with OPAT for SIRI (B-OPAT) compared with treatment as usual on key OUD, infectious disease, and health economic outcomes. B-OPAT expands and incorporates key elements of established clinical models, including inpatient initiation of buprenorphine for OUD, inpatient infectious disease consultation for SIRI, office-based treatment of OUD, and OPAT, and includes more frequent clinical outpatient visits than standard OPAT. A qualitative evaluation is included to contextualize effectiveness outcomes and identify barriers and facilitators to intervention adoption and implementation. Methods: B-OPAT is a single-site, randomized, parallel-group, superiority trial recruiting 90 adult inpatients hospitalized with OUD and SIRI who require at least 2 weeks of intravenous (IV) antibiotic therapy. After screening, eligible participants are randomized 1:1 to either discharge once medically stable to an integrated outpatient treatment care model combining Buprenorphine and OPAT (B-OPAT) or to Treatment As Usual (TAU). The primary outcome measure is the proportion of urine samples negative for illicit opioids in the 12 weeks after discharge from the hospital. Key secondary OUD outcomes include self-reported number of days of illicit opioid abstinence and 12-week retention in buprenorphine treatment. The infection outcomes are completion of recommended IV antibiotic therapy, peripherally inserted central catheter (PICC) complications, and readmission related to primary SIRI. Conclusions: The B-OPAT study will help address the important question of whether it is clinically effective and cost-effective to discharge persons with OUD and SIRI to an integrated outpatient care model combining OUD treatment with OPAT relative to TAU (Clinicaltrials.gov Identifier: NCT04677114).
RESUMEN
BACKGROUND: Syringe services programs (SSP) are an effective strategy to reduce blood-borne infections of human immunodeficiency virus (HIV) and hepatitis C virus (HCV) in persons who inject drugs (PWID). The objectives of this study were to determine the frequency and risk factors for loss to follow-up (LTFU) in PWID enrolled at SSPs in Kentucky. METHODS: A retrospective cohort study was conducted which included data of PWID enrolled at 32 SSP. Demographics, use of drugs, HIV testing, HCV testing, and medical services were analyzed. A generalized linear model (GLM), family binomial was used to determine risk factors for LTFU. RESULTS: The analysis included 5742 PWID. LTFU by year of enrollment was 287/770 (37.3%) in 2017, 796/1874 (42.5%) in 2018, and 1479/3,098 (47.7%) in 2019. LTFU was significantly associated with distance to SSP from home of more than five miles (RR 1.25; 95%CI 1.09-1.43; p = 0.002) and SSPs housed in rural counties (RR 1.22; 95%CI 1.06-1.40; p = 0.004), adjusted by age, sex, and race. The use of buprenorphine was associated with less risk of LTFU (RR 0.79, p = 0.034). CONCLUSION: The distance to an SSP from home and SSPs in rural counties were identified as risk factors for LTFU. Initiatives that bring health services closer to PWID homes and offer opioid use disorder treatment may improve repeated participation in SSPs.

Two adult patients living with AIDS presented with severe bone pain associated with tenofovir (TDF) use. Both were unable to walk without assistance and were severely restricted in their movement due to the bone pain. Both had mild renal impairment, Fanconi syndrome, and bone mineral density (BMD) loss. Bone pain and inability to walk were reversible with the cessation of TDF and supplementation with Vitamin D(3), calcium, and phosphate. These cases appear to be examples of the severity of BMD loss associated with TDF use and suggest not only attention to renal function with TDF use, but also monitoring of alkaline phosphatase (bone fraction) and plasma phosphorus as indicators of BMD loss.

PURPOSE: To determine whether lower prevaccination CD4 counts decrease odds of immune development against hepatitis A virus/hepatitis B virus (HAV/HBV) among patients who receive the vaccine and examine the relationship between vaccine response and sex, race/ethnicity, health insurance status, tobacco use, substance abuse, or comorbidities. METHODS: This study was performed among patients who received the standard dose for HAV and/or HBV vaccine. RESULTS: Among 76 HIV-infected patients, immunity development to HAV or HBV increased as CD4 counts increased. In addition, males had greater vaccine response than females. Whites were observed to have higher rates of immunity than other races/ethnicities. Patients with private insurance had greater vaccine response than those with Medicaid, Medicare, or no insurance. Patients not experiencing hypertension and hyperlipidemia developed immunity more often than patients with these comorbidities. Substance abuse and tobacco use were also associated with lower vaccine response. CONCLUSIONS: Higher CD4 counts improved likelihood of patients developing an antibody response after vaccination.

This article reviews the changing epidemiology of infections associated with injection drug use, perceived barriers to care, features of successful programs for outpatient antimicrobial treatment, models of shared decision making at the time of discharge, and linkage to preventative care after antimicrobial completion. In the search for patient-centered care associated with a rising substance use epidemic, one must continue to strive for novel collaborative approaches to ensure that each person is treated in the best way possible to successfully complete antimicrobial therapy, and then linked to a path of lifelong health care.

Introduction: The Affordable Care Act (ACA) enacted on March 23, 2010 significantly impacted access to healthcare for people living with HIV (PLWH). Expansion of care was accomplished in three areas: eliminating exclusions for pre-existing conditions, elimination of lifetime caps on healthcare expenditures, and expansion of Medicaid eligibility. Purpose: This study evaluated the impact of state implementation of the ACA Medicaid expansion on referral to HIV care at a Ryan White federally funded clinic in Kentucky (University of Kentucky Bluegrass Care Clinic [UK BCC]). Methods: Retrospective chart review of all newly enrolled patients at the UK BCC between March 2010 and June 2017. Data included patient demographics and referral source, and were divided into two groups to compare enrollments before and after Kentucky implemented the ACA Medicaid expansion. Data were collected from 2018-2019 and analyzed in 2020. Results: Following Medicaid expansion there were statistically significant changes in the patterns of referral to federally funded HIV care. These included a significant decrease in the proportion of referrals from state and local health departments, and an increase in both proportion of referrals from outpatient clinics and transfers from different HIV care providers. Implications: These results have implications for engaging more PLWH into HIV care, particularly in states where patients have increased access to screening and assessment of risk at primary care encounters through implementation of the ACA Medicaid expansion.
