NEW YORK,?Sept. 18, 2020?/PRNewswire/ --?Thanks to the generous support of donors, Hospital for Special Surgery (HSS) has announced the funding of nine grants for projects related to the study of COVID-19. These projects reflect the institution's expertise in basic, translational and clinical research, and clinical care. Over?$500,000?has been awarded so far. HSS is the world's largest academic medical center specialized in musculoskeletal health, spanning orthopedics, rheumatology and related disciplines. The HSS Research Institute maintains 20 laboratories dedicated to solving debilitating orthopedic and rheumatic conditions such as arthritis, bone and soft tissue injuries, autoimmune diseases, and musculoskeletal pain and deformities. There, more than 300 dedicated personnel focus on tissue repair, improving surgical outcomes, autoimmunity and inflammation, genomics, new treatments, and precision medicine. "HSS has a long history of contributing to the collective base of clinical and basic science knowledge?and finding healthcare solutions for complex conditions," said?Louis A. Shapiro, President and CEO, HSS. "We're proud that through the joint efforts of our institution and philanthropic support, we will have the ability to make a strong impact on this growing and vital area of research." "As experts in inflammatory disorders and in the development of interventions for overactive immune responses, the clinicians and researchers at HSS are well-positioned to investigate many of the adverse effects of COVID-19," says?Lionel B. Ivashkiv, MD, Chief Scientific Officer at the HSS Research Institute. "This includes studying the causes of these adverse effects as well as how to prevent and treat them." What follows are descriptions?of the first group of funded projects in basic/translational research: Activation of pDCs by SARS-CoV-2 and Its Impact on Macrophage Response Principal Investigator:?Franck Barrat, PhD
Co-Investigator:?Marie-Dominique Ah Kioon, PhD This project will study cell types that are responsible for cytokine storm syndrome ? the hyperactive immune response seen in people with COVID-19 ? by looking at how certain immune cells are activated by SARS-CoV-2. Research in mice infected with SARS-CoV, a coronavirus similar to the one that causes COVID-19, has suggested that plasmacytoid dendritic cell precursors (pDCs) are key to the immune response to infection. These pDCs activate macrophages, which in turn secrete cytokines. In the SARS-CoV research, depletion of pDCs appeared to protect the mice from lethal lung injury. Using blood samples from donors, the investigators will study the pathway by which pDCs activate macrophages and look at ways to therapeutically block that process. The Use of CDK7 Inhibitors to Target COVID-19?Associated Cytokine Storm Principal Investigator:?Inez Rogatsky, PhD
Co-Investigators:?Steven Josefowicz, PhD, and?Robert P. Fisher, MD, PhD This pilot project will assess the ability of cyclin-dependent kinase?(CDK) 7 inhibitors to stop the progression of the cytokine storm in people with COVID-19. This research will focus particularly on a step in RNA Polymerase II (Pol II) dynamics that is responsible for activating more than 75% of inflammation-relevant genes. CDK7 is known to play an important role in Pol II. Targeting this kinase may ultimately show promise in developing potential drugs. This research will be done using donor blood as well as blood from COVID-19 patients. Mechanisms of Cytokine Storm in Patients with COVID-19 Principal Investigator:?Mary K. Crow, MD
Co-Investigators:?Mikhail Olferiev, MD, and?Lionel B. Ivashkiv, MD The objectives of this study are to describe the process of the cytokine storm in people with COVID-19 and to identify biologic predictors of a favorable outcome in patients with severe cases of the disease. The project aims to characterize immune cell populations seen in COVID-19 patients who experience cytokine storm and compare them to those patients who do not, to compare the immune response before and after patients are given the anti-inflammatory drug anakinra, and to identify measures that suggest patients are more likely to decline and eventually require mechanical ventilation. The research will employ blood samples from HSS patients who are being treated for COVID-19 at New York?Presbyterian Hospital and who meet certain other qualifications. What follows are descriptions of the first group of funded projects in the areas of clinical and health outcomes research: Response to and Recovery from TKA in Patients with Antibodies to SARS-CoV-2 Principal Investigator:?Miguel Otero, PhD
Co-Investigators:?Meghan Kirksey, MD, PhD, and?Peter K. Sculco, MD It is unknown if people who have been exposed to COVID-19 may be at higher risk of experiencing an abnormal immune response following surgery, resulting in poor outcomes. This study will evaluate the response to and recovery from total knee arthroplasty (TKA) in people who have antibodies to COVID-19 ? a marker of exposure. This study will include both patients who have COVID-19 antibodies and those who don't, to act as controls. Patients will be followed for six weeks after surgery and evaluated for the presence of certain immune markers in the blood, as well as symptoms of inflammation including pain and stiffness in the joint. SARS-CoV-2 Exposure and the Role of Vitamin D Among Hospital Employees Principal Investigator:?Emily M. Stein, MD, MS
Co-Investigators:?Theresa T. Lu, MD, PhD;?Andy O. Miller, MD;?Jeri Nieves, PhD; and?Alana Serota, MD It is unknown if people with vitamin D deficiency may be more likely to become infected with COVID-19. This study will investigate vitamin D status and associated immune markers as risk factors for COVID-19 infection in a cohort of healthcare workers. Healthcare workers are at higher risk of contracting COVID-19 than the general population, making them a good group to study. Vitamin D is critical for immune function and is known to be protective against respiratory-tract infection and tuberculosis. This prospective, observational study will follow healthcare workers at HSS and at other healthcare facilities for one year, to determine whether levels of vitamin D and certain immune cells in the blood make someone more susceptible to COVID-19 infection. Association of Immunomodulatory Medication Use and Social Determinants of Health with COVID-19 Infection in Systemic Rheumatic Disease Patients in?New York City Principal Investigator:?Medha Barbhaiya, MD, MPH
Co-Investigators from HSS:?Lisa Mandl, MD, MPH;?Catherine MacLean, MD, PhD;?Vinicius Antao, MD, PhD;?Jane Salmon, MD; and?Mayu Sasaki, MPH
Other Co-Investigators:?Candace Feldman, MD, MPH (of Brigham and Women's Hospital);?Debra D'Angelo, MS (of Weill Cornell Medicine) Using data from the INSIGHT Clinical Research Network, a central repository containing longitudinal electronic health data for residents of?New York City, investigators will assemble a cohort of patients being treated with immunomodulatory medications for rheumatic disease. This patient population will then be used to study the effect of these medications on COVID-19 incidence and outcomes. Retrospective data will be used to evaluate the incidence and severity of COVID-19 in these patients. Patients will also be studied prospectively to determine whether there's a relationship between COVID-19 infection and future rheumatic disease as well as to study connections between infection and future psycho-social issues. Assessment of Surgical Outcomes in the COVID-19 Pandemic Era Principal Investigator:?Andy O. Miller, MD
Co-Investigators:?Scott A. Rodeo, MD,?and?Mark Fontana, PhD Investigators will implement a patient registry to evaluate how COVID-19 affects outcomes and complication rates after orthopedic surgery. This registry, along with COVID-19 screening procedures, will provide the tools to address specific research questions. Among these questions are determining the incidence of current and prior infection among the HSS surgical population, the clinical features associated with current and prior infections in this patient population, and whether COVID-19 status affects short-term complication rates. What follows is a description of an integrated multidisciplinary study being undertaken jointly by the Adult Reconstruction and Joint Replacement?(ARJR) Perioperative Research Group, Anesthesiology and Rheumatology: Prediction and Prevention of Postoperative Blood Clots in COVID-19 Patients Principal Investigators:?Friedrich Boettner, MD;?Kethy M. Jules-Elysee, MD;?Lisa A. Mandl, MD, MPH Co-Investigators:?ARJR surgeons:?Alejandro Gonzalez Della Valle, MD;?Jason Blevins, MD;?David J. Mayman, MD;?Peter K. Sculco, MD;?Geoffrey H. Westrich, MD?and?Thomas P. Sculco, MD
Medicine/Rheumatology:?Medha Barbhaiya, MD, MPH;?Doruk Erkan, MD, MPH;?Deanna Jannat-Khah, DrPH
Pathology:?Thomas W. Bauer, MD, PhD
Anesthesiology:?Stavros G. Memtsoudis, MD, PhD, MBA;?Alexandra Sideris, PhD
ARJR:?Amethia Joseph, MHA;?Ethan Krell, MS
Weill?Cornell Medicine:?Raymond David Pastore, MD Recent literature suggests that one of the major complications seen in people with COVID-19 is thrombosis (the formation of blood clots) due to endothelial dysfunction, persistent inflammation and potentially antiphospholipid antibodies. As?elective surgeries resume, those with prior exposure to SARS-CoV-2 will inevitably present for treatment, and some may have perioperative management considerations related to their risk of deep-vein thrombosis. This project will use, a noninvasive device that can determine clotting risks, to investigate whether people who have had COVID-19 have a more dysfunctional endothelium preoperatively and at 24 hours after surgery. The investigators will measure antiphospholipid antibodies and inflammatory markers, and evaluate the prevalence of asymptomatic post-operative deep-vein thrombosis in people who undergo TKR and have SARS-CoV-2 antibodies. COVID-19 Translational Research Core at HSS Principal Investigator:?Theresa Lu, MD, PhD?
Co-Investigators:?Jessica Andre?s-Bergo?s, PhD;?Miguel Otero, PhD?and?Emily M. Stein, MD, MS The COVID-19 Translational Research Core (TRC) was designed to fill critical gaps in the resources needed to promote the broad range of COVID-19?related clinical and translational research at HSS.
