An Unusual Case Of Indolent Systemic Mastocytosis: Diagnostic Insights In The Absence Of Classic Systemic Symptoms, Henry Lim, Jonah Gutierrez, Rafael Do Valle, Reem Ayoub, Marshall Hall, Christian Scheufele, Garrett Furth, Michael Carletti, Stephen Weis

North Texas Research Forum 2025

Introduction: Mastocytosis is a disorder characterized by an abnormal clonal accumulation and subsequent activation of mast cells within one or more organs. It is generally classified as either cutaneous, with or without systemic involvement, or systemic without cutaneous disease based on major and minor criterion. Indolent systemic mastocytosis (ISM) is a subclass of systemic mastocytosis with generally good prognosis. While the etiology of ISM is not completely understood, those who are affected typically have the KIT D816V mast cell receptor mutation. Given that ISM is mast cell mediated, patients predominantly present with a wide range of symptoms related to mast …

Psychology Faculty Publications

Background

Long-acting injectable pre-exposure prophylaxis (LAI-PrEP) for HIV prevention may improve adherence for those with concerns with daily pills. Limited data exist on LAI-PrEP acceptability among Black women in the U.S., a population vulnerable to HIV. We assessed willingness to use LAI-PrEP among Black women eligible for PrEP in the Southern U.S.

Methods

We conducted a cross-sectional online survey of HIV-negative Black women from March to June 2022 in the U.S. South. Participants provided information on sociodemographic characteristics, HIV knowledge, PrEP awareness, and use, stigma, risk perception, medical mistrust, and healthcare access. Multivariate logistic regression models determined factors associated with …

An Electrochemical Sensor For Tenofovir Monitoring, Abdellatif Ait Lahcen, Gymama Slaughter

Center for Bioelectronics Publications

Effective monitoring of tenofovir (TFV) adherence is critical for ensuring the success of antiretroviral therapies in preventing and managing HIV, as nonadherence can lead to treatment failure and the development of drug-resistant strains. In this study, a highly sensitive and selective novel biomimetic sensor for TFV determination is developed utilizing laser-scribed graphene (LSG) modified with gold spiky nanostructures (AuNSp) and molecularly imprinted polymer (MIP). The MIP layer is engineered with precise control to maximize molecular specificity for TFV. Electrochemical characterization demonstrates excellent performance, including the broadest linear detection range (10 nM to 200 μM) reported to date with a sensitivity …

Highly effective antiretroviral-based HIV prevention plays an important role in ending the global HIV/AIDS epidemic. However, the sustainable control of the epidemic is hampered by unequal access to prevention options, including HIV testing, alongside with drug resistance and ongoing barriers to accessing sustainable HIV treatment. Therefore, an HIV vaccine, combined with effective prevention and treatment, remains an absolute necessity to control the epidemic. Yet, the recent discontinuation of four major vaccine efficacy studies is raising concerns about the future of HIV vaccine research and development globally, and particularly in the European region where funding for vaccine research and development has …

Gut inflammatory diseases cause microbial dysbiosis. Human immunodeficiency virus-1 (HIV) infection disrupts intestinal integrity, subverts repair/renewal pathways, impairs mucosal immunity and propels microbial dysbiosis. However, microbial metabolic mechanisms driving repair mechanisms in virally inflamed gut are not well understood. We investigated the capability and mechanisms of gut microbes to restore epithelial barriers and mucosal immunity in virally inflamed gut by using a multipronged approach: an in vivo simian immunodeficiency virus (SIV)-infected nonhuman primate model of HIV/AIDS, ex vivo HIV-exposed human colorectal explants and primary human intestinal epithelial cells. SIV infection reprogrammed tryptophan (TRP) metabolism, increasing kynurenine catabolite levels that are …

Drug-Induced Leukocytoclastic Vasculitis From An Unreported Source: Daptomycin, Jennifer K. Priessnitz, Timothy Kuzel, Lindsay Ackerman, Nelson Nicolasora

Department of Medicine Faculty Publications

Leukocytoclastic vasculitis (LCV) is a rare small-vessel vasculitis caused by immune-complex-mediated deposition on endothelial cells of dermal capillaries. Common triggers include medications, infections, autoimmune disorders, and malignancies. We present a case of a 58-year-old male who developed daptomycin-induced LCV after being treated for Methicillin-resistant Staphylococcus aureus (MRSA) endocarditis. The patient experienced painful palpable purpura on his lower extremities, which was diagnosed as LCV by skin biopsy. At the time of the biopsy, warfarin and daptomycin were discontinued, and the patient was transitioned to heparin and ceftaroline. MRSA-induced LCV was ruled out, due to negative blood cultures and adequate source control …

Hiv Protein Tat Dysregulates Multiple Pathways In Human Ipscs- Derived Microglia, Liam Liyang Guo, Robert Jiang, Yan Cheng, Brooke Russell, Yan Y. Sanders, Ming-Lei Guo

Department of Biomedical and Translational Sciences Faculty Publications

In the era of combined antiretroviral therapy, around 50% of chronic HIV (+) individuals show varying degrees of memory and cognitive deficiency (NeuroHIV), a phenomenon of accelerated brain aging. HIV protein transactivator of transcription (TAT) has been well-accepted as a risk factor contributing to NeuroHIV through dysregulating microglia (Mg) functions. Previous studies have demonstrated that HIV-TAT can affect lipid metabolism, immune responses, autophagy, and senescence in rodent Mg. However, due to the significant species differences between rodent and human Mg (hMg), it is essential to take caution when interpreting the results obtained from rodent models into human conditions. For the …

Pharmacy and Wellness Review

Between 1.6 and 5.1% of the United States population have experienced anaphylaxis, a severe allergic reaction.1 Anaphylaxis occurs when someone is exposed to an allergen, most commonly foods, medications, and insect venom. Epinephrine is the first-line agent for anaphylaxis treatment, and it is critical to administer this medication immediately after the onset of anaphylactic symptoms to prevent worsening that could lead to death. Epinephrine, more commonly known as EpiPen® or Auvi-Q®, has historically only been available as an intramuscular (IM) injection. Many people are afraid, anxious, or uneducated on how to properly give someone an IM injection, causing anaphylaxis treatment …

Systemic lupus erythematosus (SLE) is an autoimmune disease that more commonly affects African American people, although it is seen in people of all racial backgrounds. This condition is characterized by a dysregulated immune response resulting in widespread inflammation. Clinical manifestations caused by this inflammation include arthritis, anemia, cutaneous rashes, pleuritis, and nephritis. Treatment for SLE aims to reduce disease activity and maintain a state of low inflammation. In this regard, numerous treatments are used, such as hydroxychloroquine, glucocorticoids, and non-glucocorticoid immunosuppressants such as methotrexate. Related to these drugs resulting in significant adverse effects and being ineffective in controlling SLE symptoms …

Differences In Igg Afucosylation Between Groups With And Without Carotid Atherosclerosis, Cuihong Tian, Xingang Li, Hongxia Zhang, Jieyi He, Yan Zhou, Manshu Song, Peixuan Yang, Xuerui Tan

Research outputs 2022 to 2026

Background: A previous study demonstrated that N-glycosylation profiles of IgG are associated with subclinical atherosclerosis in a British population. However, the generalisability of this finding to other ethnic groups remains to be investigated, and it has yet to account for additional traditional atherosclerotic risk factors. The present study, thus, aims to explore IgG N-glycosylation profiles in Han Chinese with atherosclerosis, and their potential role in atherosclerosis, while controlling for traditional atherosclerotic risk factors. Methods: Data of this case-control study were obtained from an established umbrella Health Examination Cohort Study (registration number: ChiCTR2100048740). The investigation was conducted at the Health Care …

Oscillometry Changes Reflect Clinically Meaningful Improvement After Bronchial Thermoplasty For Uncontrolled Asthma: A Case Report, Niranjan Setty, Alice Crawford, Brooke Kyle, Dhaval Thakkar, Rajesh Thomas, John Blakey

Research outputs 2022 to 2026

Asthma is a highly prevalent but heterogenous condition. Uncontrolled disease is relatively common and may be due to ongoing inflammation and/or persisting bronchial hyper-reactivity. Bronchial thermoplasty has been in use for many years but optimal case selection and post-procedure assessment remain uncertain. We present a case of a gentleman in his 50s with lifelong asthma who experienced a persistent loss of control following influenza A in 2017. Despite multidisciplinary assessment and guideline-based escalation of therapy, he had persisting symptoms. In the context of his atopy, he was trialled unsuccessfully on dupilumab. Bronchial thermoplasty (BT) was undertaken with good clinical benefit. …

Crosstalk Between Cytokines And Igg N-Glycosylation: Bidirectional Effects And Relevance To Clinical Innovation For Inflammatory Diseases, Zhixian Chen, Xiaojia Xu, Manshu Song, Ling Lin

Research outputs 2022 to 2026

The crosstalk between cytokines and immunoglobulin G (IgG) N-glycosylation forms a bidirectional regulatory network that significantly impacts inflammation and immune function. This review examines how various cytokines, both pro- and anti-inflammatory, modulate IgG N-glycosylation, shaping antibody activity and influencing inflammatory responses. In addition, we explore how altered IgG N-glycosylation patterns affect cytokine production and immune signaling, either promoting or reducing inflammation. Through a comprehensive analysis of current studies, this review underscores the dynamic relationship between cytokines and IgG N-glycosylation. These insights enhance our understanding of the mechanisms underlying inflammatory diseases and contribute to improved strategies for disease prevention, diagnosis, monitoring, …
