Respiratory syncytial virus (RSV) is a leading cause of intensive care unit (ICU) admission and respiratory failure among infants (children aged < year) in the United States. In August 2023, CDC’s Advisory Committee on Immunization Practices recommended nirsevimab, a long-acting monoclonal antibody, to protect against RSV-associated lower respiratory tract infection among all infants aged < 8 months born during or entering their first RSV season. Following licensure, nirsevimab effectiveness has been demonstrated against RSV-associated infant hospitalization, but evidence regarding effectiveness against RSV-associated critical illness is limited. In a 27-hospital case-control investigation, nirsevimab effectiveness against both RSV-associated infant ICU admission and acute respiratory failure (illness requiring continuous positive airway pressure, bilevel positive airway pressure, or invasive mechanical ventilation) after hospital admission was evaluated during December 1, 2024-April 15, 2025. Among 457 case-patients who received a positive RSV test result and 302 control patients who received a negative RSV test result admitted to an ICU with respiratory symptoms, 14% and 45%, respectively, had received nirsevimab ≥ 7 days before symptom onset. Nirsevimab was 80% effective (95% CI = 70%-86%) against RSV-associated ICU admission and 83% effective (95% CI = 74%-90%) against acute respiratory failure when received a median of 52 days (IQR = 32-89 days) and 50 days (IQR = 32-86 days) before onset for each respective endpoint. These estimates support the recommendation for use of nirsevimab as a prevention strategy to protect infants against severe outcomes from RSV infection.

Rethinking Congenital Cytomegalovirus: A Narrative Review Of The Clinical, Public Health, And Ethical Challenges Of A Preventable Cause Of Childhood Hearing Loss, M. Peyton Simons, Gauri Mankekar

School of Medicine Faculty Publications

Congenital cytomegalovirus (cCMV) is the most common non-genetic cause of pediatric sensorineural hearing loss, affecting approximately tens of thousands of infants annually in the United States. While cCMV may present symptomatically at birth, many infants are asymptomatic initially and later develop progressive or fluctuating hearing loss, which is often undiagnosed without early screening. Despite advances in diagnostic methods such as polymerase chain reaction (PCR) testing, the absence of a national screening policy in the U.S. results in significant variability in early detection and follow-up care. This narrative review provides an overview of the clinical manifestations, diagnostic strategies, and treatment options …

Life Course Stressors, Latent Coping Strategies, Alcohol Use, And Adherence Among People With Hiv, Amrita Gill, Gretchen Clum, Patricia Molina, David Welsh, Tekeda Ferguson, Katherine P. Theall

School of Medicine Faculty Publications

People with HIV (PWH) have often experienced chronic stressors across their lifespan, including adverse childhood experiences (ACES), lifetime economic hardship (LEH), and concurrent stressors associated with living in urban areas (urban stress). Prolonged exposure to stressors might result in differential coping patterns among PWH that can impact care trajectories. We utilized a life course-informed approach to examine chronic stressors as antecedents of latent coping strategies among PWH in care. High-risk alcohol use and non-adherence to anti-retroviral therapy (ART) were examined as consequences of latent coping strategies. Data were utilized from the baseline and interim follow-up visit of the New Orleans …

The popularity of e-cigarettes (vaping) has soared, creating a public health crisis among teens and young adults. Chronic vaping can induce gut inflammation and reduce intestinal barrier function through the production of the proinflammatory molecule hydrogen sulfide (H2S). This is particularly concerning for people with HIV (PWH) as they already face impaired immune function and are at a higher risk for metabolic dysregulation, diabetes, and chronic liver disease. Furthermore, PWH experience unhealthy behaviors, making it crucial to understand the systemic metabolic dysregulation and pathophysiological mechanisms associated with vaping in this population. Here, we employed liquid chromatography–mass spectrometry (LC-MS)-based metabolomics to …

Perivascular macrophages (PVMs) and, to a lesser degree, microglia are targets and reservoirs of HIV and simian immunodeficiency virus (SIV) in the brain. Previously, we demonstrated that colony-stimulating factor 1 receptor (CSF1R) in PVMs was upregulated and activated in chronically SIV-infected rhesus macaques with encephalitis, correlating with SIV infection of PVMs. Herein, we investigated the role of CSF1R in the brain during acute SIV infection using BLZ945, a brain-penetrant CSF1R kinase inhibitor. Apart from three uninfected historic controls, nine Indian rhesus macaques were infected acutely with SIVmac251 and divided into three groups (n = 3 each): an untreated control and …

About one-fourth of patients with pancreatic ductal adenocarcinoma (PDAC) are categorized as borderline resectable (BR) or locally advanced (LA). Chemotherapy and radiation therapy have not yielded the anticipated outcomes in curing patients with BR/LA PDAC. The surgical resection of these tumors presents challenges owing to the unpredictability of the resection margin, involvement of vasculature with the tumor, the likelihood of occult metastasis, a higher ratio of positive lymph nodes, and the relatively larger size of tumor nodules. Oncolytic virotherapy has shown promising activity in preclinical PDAC models. Unfortunately, the desmoplastic stroma within the PDAC tumor microenvironment establishes a barrier, hindering …

BACKGROUND: The CDC and ACIP recommend COVID-19 vaccination for patients with inborn errors of immunity (IEI). Not much is known about vaccine safety in IEI, and whether vaccination attenuates infection severity in IEI. OBJECTIVE: To estimate COVID-19 vaccination safety and examine effect on outcomes in patients with IEI. METHODS: We built a secure registry database in conjunction with the US Immunodeficiency Network to examine vaccination frequency and indicators of safety and effectiveness in IEI patients. The registry opened on January 1, 2022, and closed on August 19, 2022. RESULTS: Physicians entered data on 1245 patients from 24 countries. The most …

Seasonal coronaviruses (HCoVs) are known to contribute to cross-reactive antibody (Ab) responses against SARS-CoV-2. While these responses are predictable due to the high homology between SARS-CoV-2 and other CoVs, the impact of these responses on susceptibility to SARS-CoV-2 infection in cancer patients is unclear. To investigate the influence of prior HCoV infection on anti-SARS-CoV-2 Ab responses among COVID-19 asymptomatic individuals with cancer and controls without cancers, we utilized the VirScan technology in which phage immunoprecipitation and sequencing (PhIP-seq) of longitudinal plasma samples was performed to investigate high-resolution (i.e., epitope level) humoral CoV responses. Despite testing positive for anti-SARS-CoV-2 Ab in …

Background: Hypercytokinemia, the renin-angiotensin system, hypoxia, immune dysregulation, and vasculopathy with evidence of immune-related damage are implicated in brain morbidity in COVID-19 along with a wide variety of genomic and environmental influences. There is relatively little evidence of direct SARS-CoV-2 brain infection in COVID-19 patients. Methods: Brain histopathology of 36 consecutive autopsies of patients who were RT-PCR positive for SARS-CoV-2 was studied along with findings from contemporary and pre-pandemic historical control groups. Immunostaining for serum and blood cell proteins and for complement components was employed. Microcirculatory wall complement deposition in the COVID-19 cohort was compared to historical control cases. Comparisons …

The increased risk for acquiring secondary illnesses in people living with HIV (PLWH) has been associated with immune dysfunction. We have previously found that circulating monocytes from PLWH display a trained phenotype. Here, we evaluated the metabolic profile of these cells and found increased mitochondrial respiration and glycolysis of monocyte-derived macrophages (MDMs) from PLWH. We additionally found that cART shifted the energy metabolism of MDMs from controls toward increased utilization of mitochondrial respiration. Importantly, both downregulation of IKAROS expression and inhibition of the mTOR pathway reversed the metabolic profile of MDMs from PLWH and cART-treated control-MDMs. Altogether, this study reveals …

Elevated D-dimer and fibrinogen level, mild thrombocytopenia, modest prolongation of prothrombin time, and activated partial thromboplastin time, are key indicators of coagulopathy, and have been consistently reported in severely ill COVID-19 patients. Coronavirus disease 2019 (COVID-19)-induced coagulopathy can develop serious venous and arterial thromboembolic complications. Endothelial dysfunction and hypercoagulability, triggered mostly by overproduction of inflammatory cytokines as an immune response to the infection, are the pivotal factors responsible for the above-mentioned coagulation disorder. Thus, low-molecular-weight heparin (LMWH), which has both anticoagulant and anti-inflammatory properties, has been reported to improve disease prognosis. However, there have been increasing reports of venous thromboembolic …

INTRODUCTION: Profound sexual health disparities exist for Black men who have sex with men (MSM) in the US South, including a high prevalence of sexually transmitted infections (STIs). Sexually transmitted infection prevention strategies beyond condoms are needed for Black MSM taking preexposure prophylaxis (PrEP). METHODS: We conducted in-depth interviews with Black MSM taking PrEP in New Orleans, Louisiana. Informed by the Health Belief Model, we asked about participants' perceived susceptibility, severity, and concerns regarding STIs, and perceived benefits of STI prevention. We also asked about willingness to use various STI prevention strategies, including antibiotic prophylaxis. Interviews were audio-recorded and analyzed …
