Dear Colleague:

Are you treating patients with any of these conditions?

  • HIV
  • Hepatitis C
  • Lyme disease
  • Eosinophilic esophagitis

I encourage you to tell your patients about research studies for these and other infectious and inflammatory diseases being conducted by the National Institute of Allergy and Infectious Diseases (NIAID) at the National Institutes of Health (NIH) campus in Bethesda, Maryland.

Clinical studies are vital to developing new treatments that ease human suffering and save lives. Eligible study participants will receive study-related medical exams and medications at no cost, and they may be compensated for their time. NIH is easily accessible by Metrorail.

For more information, please visit or call
1-800-411-1222 (TTY: 1-866-411-1010, se habla Español).

Thank you for your consideration.
