The Vasculitis and Rare Disease Clinic at Washington University School of Medicine is a leading center for the management and treatment of rare autoimmune diseases. Under the expert leadership of Colin Diffie, MD, and Aisha Shaikh, MD, our clinic has experienced remarkable growth since its establishment in 2017. We pride ourselves in serving a diverse range of patients with rare autoimmune conditions, including ANCA associated vasculitis and even esoteric diseases that have yet to be named or fully understood.

At our clinic, we prioritize collaboration and comprehensive care. Our esteemed vasculitis team holds regular case review conferences, where we discuss and strategize the management of complex cases. We work closely with world-class partners in various specialties such as pulmonary, ENT, ophthalmology, dermatology, nephrology, and others to ensure that our patients receive customized treatment.

The Vasculitis and Rare Disease Clinic specializes in the diagnosis and management of various conditions, including but not limited to:

  • Granulomatosis with Polyangiitis
  • Microscopic Polyangiitis
  • Eosinophilic Granulomatosis with Polyangiitis
  • Takayasu’s Arteritis
  • Leukocytoclastic Vasculitis
  • Giant Cell Arteritis
  • All variants of small, medium, and large vessel vasculitis
  • Polymyalgia Rheumatica

We are dedicated to advancing our understanding and treatment of rare autoimmune diseases through ongoing research and collaboration. Our goal is to provide our patients with the highest quality of care and support as we continue to expand our expertise in the field of vasculitis and rare diseases.

The vasculitis team will be joined by a new faculty member Dr. Andrew Jones in 2024. Dr. Jones is currently a 3rd year rheumatology fellow in our rheumatology division with focused training on management of vasculitis patients.
