About the Investigator

Dr. Meggan Mackay is a rheumatologist whose primary interests are in systemic lupus erythematosus, rheumatoid arthritis, Scleroderma and vasculitis.  Dr. Mackay is a graduate of New York Medical College where she was awarded the New York Medical College Trustee Scholarship for Academic Excellence and was a junior inductee into the Alpha Omega Alpha Honor Society. She obtained a Master of Science from the Clinical Research Training Program at the Albert Einstein College of Medicine.

Prior to her arrival at the Feinstein Institute, Dr. Mackay had been on the faculty at Columbia University Medical Center and the Albert Einstein College of Medicine where she was the Associate Director of Medicine at Jacobi Medical Center.  At Einstein she was awarded the Davidoff Teaching Award and the Harry Gordon Award for Outstanding Clinical Teaching. She has worked extensively with the Arthritis Foundation, the SLE Foundation and the Lupus Alliance to promote community awareness and education about lupus, rheumatoid arthritis and other rheumatologic diseases.

Research Focus

Dr. Meggan Mackay and Dr. Cynthia Aranow are co-directors of the Clinical Trials Unit under their chairperson, Dr. Betty Diamond. Both Drs. Mackay and Aranow are specialists in Rheumatology with additional expertise in lupus. They have extensive experience in running and designing clinical trials as well as in other types of research studies. The Center for Autoimmune, Musculoskeletal and Hematopoietic Diseases is comprised of investigators in basic science and clinical medicine and the collaborative efforts between basic scientists and clinical investigators has resulted in the Center’s unique ability to study autoimmune disease using innovative methods.

The Center for Autoimmune, Musculoskeletal and Hematopoietic Diseases focuses its research efforts on Systemic Lupus Erythematosus and rheumatoid arthritis in addition to other autoimmune diseases. We have established several clinics in St. Albans, Queens, the Bronx, Manhattan and Long Island (Garden City and at The Feinstein Institute in Manhasset) and are committed to caring for all patients regardless of reimbursement. All patients are encouraged to participate in clinical research efforts. Involvement in research can be a powerful means for patients to learn more about their disease and know that they are contributing to the fight for a cure. Clinical research does not always mean testing new medications; there are three kinds of clinical research; Observational Studies, Translational Studies and Clinical Trials.

Observational Studies collect information on patient as they are followed regularly in the clinics and do not involve new medications or invasive procedures. These studies help determine how things like gender, age, environment, medications and ethnicity may affect outcomes of patients with autoimmune disease. All information collected in these studies is coded so that it is difficult for information to be linked directly to an individual patient and patient confidentiality is preserved.

Translational Studies use blood, urine or tissue samples combined with clinical information from patients to study abnormalities in the immune system, discover how they contribute to autoimmune disease and identify targets for the development of new therapies. These types of studies can also include genetic testing to help understand why some individuals are at higher risk for developing autoimmune disease than others.

Clinical Trials are studies that are designed to test new medications or existing medications that have already been approved for a different disease.

Research projects currently ongoing in the Clinical Trials Unit include observational studies of brain involvement in lupus, many translational studies of immune dysfunction in Lupus and Rheumatoid Arthritis and many clinical trials of new medications for Lupus, Rheumatoid Arthritis and Scleroderma. We are happy to see any patients diagnosed with autoimmune disease or those who have been told they may have one of these diseases.

Although we specialize in adult medicine, adolescent and pediatric patients are welcome! Please call our Feinstein Lupus Hotline with any questions or to schedule an appointment: 1-877-33 LUPUS (1-877-335-8787)
