“A lot of people are either being diagnosed or self-diagnosing (with MCAS), I would say somewhat inappropriately, without any actual evidence of mast cell activation. We’re seeing it more and more commonly.”​

– Dr. Tim Olynych

On this episode of The Allergist, Dr. Mariam Hanna teams up with Dr. Timothy Olynych, a clinical immunologist and allergist and PhD in mast cells, to unravel the mystery of mast cell activation syndrome (MCAS). This elusive condition requires some serious detective work, with clues scattered across a complex array of symptoms that don’t always add up. Together, they crack the case on how to spot MCAS in its various disguises and offer a roadmap for managing this puzzling disorder.

In this episode:

  • Understanding Mast Cell Activation Syndrome: MCAS is a complex condition characterized by a constellation of symptoms rather than one clear diagnostic feature. Dr. Olynych highlights why it’s often confused with other conditions, making diagnosis a challenge for clinicians.
  • The Role of Tryptase Testing: Learn how tryptase testing is crucial in diagnosing MCAS, especially when levels spike during symptom flares, though normal levels don’t always rule out MCAS.
  • Common Misconceptions and Comorbidities: Dr. Olynych addresses the frequent confusion between MCAS and conditions like POTS and Ehlers-Danlos syndrome.
  • Treatment Approaches: Dr. Olynych outlines a treatment approach that mirrors how chronic spontaneous urticaria is managed, using H1 and H2 blockers and mast cell stabilizers like cromolyn sodium.
  • Patient Care Beyond the Allergist’s Office: This episode highlights the importance of a multidisciplinary approach to MCAS, including when to refer patients to other specialists.

Join us as we dig deeper into the enigma of mast cell activation syndrome, uncovering practical clues and actionable insights for healthcare providers eager to crack the case on this complex and often misunderstood condition.
