Case Report: Disseminated Herpes Simplex Virus Complicated By Hemophagocytic Lymphohistiocytosis In A Neonate, Nicholas Tadros, Nihal Godiwala Jan 2025

Case Report: Disseminated Herpes Simplex Virus Complicated By Hemophagocytic Lymphohistiocytosis In A Neonate, Nicholas Tadros, Nihal Godiwala

School of Medicine Faculty Publications

Neonatal herpes simplex virus (HSV) infection carries a high mortality rate due to its potential to cause disseminated disease involving multiple organ systems, which can rapidly progress to shock and death if not promptly treated. In rare cases, neonates may mount an uncontrolled inflammatory response leading to hemophagocytic lymphohistiocytosis (HLH), a severe hyperinflammatory syndrome. We present a case of neonatal HSV infection complicated by HLH, highlighting the challenges of managing both conditions concurrently. Our therapeutic approach demonstrated a reduction in systemic inflammation and viral load; however, despite these efforts, the patient developed multiorgan failure and ultimately died from the initial …

Management of bleeding in persons with hemophilia and inhibitors involves treatment with bypassing agents, including recombinant activated factor VII (rFVIIa). Two rFVIIa products are commercially approved for use in the United States and the European Union. Eptacog alfa and eptacog beta share the same amino acid sequence but differ in posttranslational modifications. Although rFVIIa has been used to manage bleeding in persons with hemophilia and inhibitors for over 30 years, its mechanisms of action is still being studied. In vitro and in vivo studies have suggested that rFVIIa could promote hemostasis by (1) increasing tissue factor-dependent activation of factor (F)X …


Tissue Kallikrein 1 Cleaves Complement Factor C3 And Activates The Alternative Complement Pathway, Sarah E. Sartain, Andrew Yee, Paula Jacobi Jan 2025

Tissue Kallikrein 1 Cleaves Complement Factor C3 And Activates The Alternative Complement Pathway, Sarah E. Sartain, Andrew Yee, Paula Jacobi

Research Data

Hematopoietic stem cell transplant-associated thrombotic microangiopathy (HSCT-TMA), characterized by microvascular endothelial damage and severe renal injury, negatively affects HSCT survivorship with high mortality and long-term renal morbidity. After HSCT, innate immunity and inflammation are often dysregulated. The alternative complement pathway (AP) of the innate immune system is overactivated in HSCT-TMA, but the mechanisms of its initiation are poorly described. Complement component C3 of the AP can be cleaved by proteases outside of the AP. Because mRNA expression of tissue kallikrein 1 (KLK1), an inflammatory serine protease that produces kinins, has been found to be markedly elevated in the renal endothelium …

Objectives: Sickle cell disease (SCD) is associated with several cardiovascular adverse events. Corrected QT (QTc) interval prolongation is one of the potential life-threatening complications that predispose patients to sudden cardiac death. This study aims to assess the prevalence of electrocardiogram (ECG) changes and to investigate risk factors associated with increased propensity of QTc prolongation. Methods: This study utilized data from the Cooperative Study of Sickle Cell Disease Cardiac Ancillary Study. QT intervals were corrected using the Bazett formula, and prolongation was defined using sex-specific thresholds. The study population included African American patients with steady-state SCD across four clinical centers located …

Delayed hemolytic transfusion reaction (DHTR) poses a significant challenge in patients receiving blood transfusions. This case report highlights the complexities of managing DHTR in a newly diagnosed chronic myelomonocytic leukemia (CMML) patient with clinically significant JKa and little c antibodies during induction chemotherapy. A 46-year-old woman with CMML-2 who presented for induction chemotherapy was found to have hemolytic anemia. Due to presence of JKa and little c antibodies, she required intensive monitoring and supportive care measures. The coexistence of JKa and little c antibodies complicates transfusion management and chemotherapy tolerance in CMML patients.

Patients with chronic lymphocytic leukemia (CLL) respond well to initial treatment with the B-cell lymphoma 2 (BCL2) inhibitor venetoclax. Upon relapse, they often retain sensitivity to BCL2 targeting, but durability of response remains a concern. We hypothesize that targeting both BCL2 and B-cell lymphoma-extra large (BCLXL) will be a successful strategy to treat CLL, including for patients who relapse on venetoclax. To test this hypothesis, we conducted a pre-clinical investigation of LP-118, a highly potent inhibitor of BCL2 with moderate BCLXL inhibition to minimize platelet toxicity. This study demonstrated that LP-118 induces efficient BAK activation, cytochrome C release, and apoptosis …

High-grade B-cell lymphoma not otherwise specified (HGBCL, NOS) has overlapping morphological and genetic features with diffuse large B-cell lymphoma (DLBCL) and Burkitt lymphoma (BL), leading to uncertainty in its diagnosis and clinical management. Using functional genomic approaches, we previously characterized HGBCL and NOS, that demonstrate gene expression profiling (GEP), and genetic signatures similar to BL. Herein, we characterize distinct HGBCL, NOS, cohort (n = 55) in adults (n = 45) and in children (n = 10), and compared the GEP, genomic DNA copy number (CN), and mutational spectrum with de novo DLBCL (n = 85) and BL (n = 52). …

Despite the burden of chronic pain in sickle cell disease (SCD), nonpharmacological approaches remain limited. This multisite, randomized trial compared digital cognitive behavioral therapy (CBT) with a digital pain/SCD education program ("Education") for managing pain and related symptoms. Participants were recruited virtually from seven SCD centers and community organizations in the United States. Adults (aged ≥18 years) with SCD-related chronic pain and/or daily opioid use were assigned to receive either CBT or Education for 12 weeks. Both groups used an app with interactive chatbot lessons and received personalized health coach support. The primary outcome was the change in pain interference …


Transplant-Associated Tma: The Conundrum Of Diagnosis And Treatment, Ang Li, Sarah E Sartain Dec 2024

Transplant-Associated Tma: The Conundrum Of Diagnosis And Treatment, Ang Li, Sarah E Sartain

Faculty, Staff and Students Publications

Transplant-associated thrombotic microangiopathy (TA-TMA) after hematopoietic cell transplantation is characterized by microangiopathic hemolytic anemia (MAHA) with persistent schistocytosis, elevated markers of hemolysis, thrombocytopenia, and microvascular thrombosis leading to ischemic injuries in the kidneys and other organs. The initial evaluation of the disease requires confirmation of non-immune MAHA and careful examination of known secondary causes of TMA. Due to increased likelihood of long-term renal failure and overall mortality, a rapid diagnosis and treatment of the underlying trigger is needed. However, the diagnostic criteria proposed to define TA-TMA remain insufficient. sC5b9, the soluble form of the membrane attack complex of the terminal …

Faculty, Staff and Student Publications

The ongoing development of molecularly targeted therapies in addition to the new standard of care combination of azacitidine and venetoclax (AZA-VEN) has transformed the prognostic outlook for older, transplant-ineligible patients with acute myeloid leukemia (AML). While conventional treatments, such as standard anthracycline and cytarabine- based chemotherapy or hypomethylating agent (HMA) monotherapy, are associated with a generally poor prognosis in this patient population, the use of these novel regimens can result in long-lasting, durable remissions in select patient subgroups. Furthermore, the simultaneous discovery of resistance mechanisms to targeted therapies and AZA-VEN has enabled the identification of patient subgroups with inferior outcomes, …

Acquired hemophilia A (AHA) is an autoimmune bleeding disorder that is caused by factor VIII (FVIII) autoantibodies with high morbidity and mortality due to bleeding and complications from immunosuppression (IST). To address the real-world implications of the FVIII mimetic antibody, emicizumab, and the role of IST, we retrospectively collected de-identified data on 62 patients with AHA who were treated off-label with emicizumab for a median of 10 weeks at 12 US-based hemophilia treatment centers. Most patients (95.2%) had acute bleeding at diagnosis, and 62.9% had partial or no control of bleeds despite the use of hemostatic agents at the time …

Cardeza Foundation for Hematologic Research

Current guidelines for treating vaccine-induced immune thrombotic thrombocytopenia (VITT) recommend nonheparin anticoagulants and IV immunoglobulin (IVIg). However, the efficacy of these treatments remains uncertain due to case studies involving small patient numbers, confounding factors (eg, concurrent treatments), and a lack of animal studies. A recent study proposed danaparoid and heparin as potential VITT therapies because of their ability to disrupt VITT IgG-platelet factor 4 (PF4) binding. Here, we examined the effects of various anticoagulants (including unfractionated [UF] heparin, danaparoid, bivalirudin, fondaparinux, and argatroban), IVIg, and the FcγRIIa receptor-blocking antibody, IV.3. Our investigation focused on VITT IgG-PF4 binding, platelet activation, thrombocytopenia, …

Acquired hemophilia is a condition characterized by the unexpected onset of severe bleeding due to an issue with coagulation factors. Typically, this disorder results from the production of autoantibodies against the Factor VIII coagulation factor. Although acquired hemophilia is an extremely rare condition, with an annual incidence of just 1.5 cases per million, it is crucial to recognize and understand it. This is because diagnosing this disorder is intricate, and if left undiagnosed and untreated, it can lead to high levels of morbidity and mortality. This case stands out as the condition typically targets older adults, with around 80% of …
