Item IVIG Delays Onset in a Mouse Model of Gerstmann-Sträussler-Scheinker Disease(Springer Nature, 2019-04) Gu, Huiying; Kirchhein, Yvonne; Zhu, Timothy; Zhao, Gang; Peng, Hongjun; Du, Eileen; Liu, Junyi; Mastrianni, James A.; Farlow, Martin R.; Dodel, Richard; Du, Yansheng; Neurology, School of MedicineOur previous studies showed that intravenous immunoglobulin (IVIG) contained anti-Aβ autoantibodies that might be able to treat Alzheimer's disease (AD). Recently, we identified and characterized naturally occurring autoantibodies against PrP from IVIG. Although autoantibodies in IVIG blocked PrP fibril formation and PrP neurotoxicity in vitro, it remained unknown whether IVIG could reduce amyloid plaque pathology in vivo and be used to effectively treat animals with prion diseases. In this study, we used Gerstmann-Sträussler-Scheinker (GSS)-Tg (PrP-A116V) transgenic mice to test IVIG efficacy since amyloid plaque formation played an important role in GSS pathogenesis. Here, we provided strong evidence that demonstrates how IVIG could significantly delay disease onset, elongate survival, and improve clinical phenotype in Tg (PrP-A116V) mice. Additionally, in treated animals, IVIG could markedly inhibit PrP amyloid plaque formation and attenuate neuronal apoptosis at the age of 120 days in mice. Our results indicate that IVIG may be a potential, effective therapeutic treatment for GSS and other prion diseases.Item The Kawasaki Disease Comparative Effectiveness (KIDCARE) trial: A phase III, randomized trial of second intravenous immunoglobulin versus infliximab for resistant Kawasaki disease(Elsevier, 2019-04) Roberts, Samantha C.; Jain, Sonia; Tremoulet, Adriana H.; Kim, Katherine K.; Burns, Jane C.; Anand, Vikram; Anderson, Marsha; Ang, Jocelyn; Ansusinha, Emily; Arditi, Moshe; Ashouri, Negar; Bartlett, Allison; Chatterjee, Archana; DeBiasi, Roberta; Dekker, Cornelia; DeZure, Chandani; Didion, Lisa; Dominguez, Samuel; El Feghaly, Rana; Erdem, Guliz; Halasa, Natasha; Harahsheh, Ashraf; Jackson, Mary Anne; Jaggi, Preeti; Jain, Supriya; Jone, Pei-Ni; Kaushik, Neeru; Kurio, Gregory; Lillian, Anna; Lloyd, David; Manaloor, John; McNelis, Amy; Michalik, David E.; Newburger, Jane; Newcomer, Charles; Perkins, Tiffany; Portman, Michael; Romero, Jose; Ronis, Tova; Rowley, Anne; Schneider, Kathryn; Schuster, Jennifer; Sexson Tejtel, S. Kristen; Sharma, Kavita; Simonsen, Kari; Szmuszkovicz, Jacqueline; Truong, Dongngan; Wood, James; Yeh, Sylvia; Pediatrics, School of MedicineBackground Although intravenous immunoglobulin (IVIG) is effective therapy for Kawasaki disease (KD), the most common cause of acquired heart disease in children, 10–20% of patients are IVIG-resistant and require additional therapy. This group has an increased risk of coronary artery aneurysms (CAA) and there has been no adequately powered, randomized clinical trial in a multi-ethnic population to determine the optimal therapy for IVIG-resistant patients. Objectives The primary outcome is duration of fever in IVIG-resistant patients randomized to treatment with either infliximab or a second IVIG infusion. Secondary outcomes include comparison of inflammatory markers, duration of hospitalization, and coronary artery outcome. An exploratory aim records parent-reported outcomes including signs, symptoms and treatment experience. Methods The KIDCARE trial is a 30-site randomized Phase III comparative effectiveness trial in KD patients with fever ≥36 h after the completion of their first IVIG treatment. Eligible patients will be randomized to receive either a second dose of IVIG (2 g/kg) or infliximab (10 mg/kg). Subjects with persistent or recrudescent fever at 24 h following completion of the first study treatment will cross-over to the other treatment arm. Subjects will exit the study after their first outpatient visit (5–18 days following last study treatment). The parent-reported outcomes, collected daily during hospitalization and at home, will be compared by study arm. Conclusion This trial will contribute to the management of IVIG-resistant patients by establishing the relative efficacy of a second dose of IVIG compared to infliximab and will provide data regarding the patient/parent experience of these treatments.Item Multisystem inflammatory syndrome in adults: A case in a previously healthy adult(Wiley, 2021-10) Motzkus, Christine A.; Whitaker, Nash; Lommel, Jennifer; Pettit, Nicholas; Emergency Medicine, School of MedicineA 25-year-old previously healthy female presented to the emergency department (ED) with 5 days of rash, fevers, shortness of breath, and generalized weakness. She had presented to another ED 4 days previously and noted that her rash had improved, but her other symptoms were worsening. She had recovered from COVID-19, confirmed by positive antigen test 5 weeks prior. On ED arrival, she was afebrile and persistently tachycardic to a rate of 120 beats per minute, despite aggressive fluid resuscitation with 3L of IV crystalloid. She was found to have a troponin elevated to 0.06 ng/mL in addition to a d-dimer elevated to 1.42 mcg/mL FEU. She was admitted to the hospital where she developed hypotension requiring vasopressor support and was admitted to the intensive care unit (ICU). A transthoracic echocardiogram revealed a newly reduced ejection fraction of 31%. She was diagnosed with multisystem inflammatory syndrome in adults (MIS-A). The patient received intravenous immunoglobulin and methylprednisolone 60 mg Q12 hours while admitted. She was discharged on hospital day 3 with a prednisone taper and is currently doing well at her most recent follow-up with infectious disease.
