Leonard Calabrese, D.O.
R.J. Fasenmyer Chair of Clinical Immunology

Maintaining a Healthy Immune System

Dear Friends and Patients,

           The following document is a monograph written by Dr. Leonard Calabrese, one of the most important teachers, clinicians and researchers in rheumatology and immunology today. This title was written for patient’s that see Dr. Calabrese at the Cleveland Clinic. He believes as I do that it is not just medications that make the difference in health, but what the patient does to maintain a healthy lifestyle combined with an accurate diagnosis and appropriate medication management. Dr. Calabrese generously gave me permission to reproduce his excellent patient manual to share with patients at our clinic as well. I urge you to make good use of it. You will be glad you did.


If you are not a patient of ours and are experiencing symptoms that are undiagnosed and/or uncontrolled, you might have an autoimmune disease. Ask your primary care for a referral to our clinic where we will do a complete investigation of your symptoms through clinical examination and the latest diagnostic testing. 

Wishing you good health,
W Richard Horn, NP
