About the researcher:

Member of Feinstein Institute for Medical Research


Autoimmune & Musculoskeletal Disease

Dr. Meggan Mackay is a rheumatologist whose primary interests are in systemic lupus erythematosus,rheumatoid arthritis, Scleroderma and vasculitis.  Dr. Mackay graduated from 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 received a Master of Science from the Clinical Research Training Program at the Albert Einstein College of Medicine.

Before 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 further 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 increased expertise in lupus. They have experience in designing and running clinical trials as well as in other types of research studies. The Center for Autoimmune Disease is composed of investigators in basic science and clinical medicine and the collaborative efforts between basic both have resulted in the Center’s unique ability to study autoimmune disease using innovative methods.

The Center for Autoimmune Disease focuses its research on Systemic Lupus Erythematosus and rheumatoid arthritis in addition to other autoimmune diseases. We have established several clinics in St. Albans, Manhattan, Queens, the  Bronx and Long Island (Garden City and at The Feinstein Institute in Manhasset) and are dedicated to caring for all patients regardless of reimbursement. All patients are encouraged to partake in clinical research efforts. Involvement in research can be a powerful means for patients to become more educated 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; Clinical Trials, Observational Studies and Translational Studies.

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

Observational Studies gathers information on patient as they are followed regularly in the clinics and do not involve new medications or procedures. These studies help determine how things like environment, age, gender, 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.

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)
