What are Mast Cells?
Mast cells are a type of white blood cell that is found in tissue throughout the body. These specialized cells play an important role in a healthy immune system, allowing the body to fight bacterial, viral, and parasitic infections.
What is Mast Cell Activation Syndrome (MCAS)?
Mast cell activation syndrome (MCAS) is a disorder of the mast cells that causes them to release an overabundance of mediators. This release is often in response to non-life-threatening conditions.
Diagnosing MCAS
Diagnosing MCAS comes with a variety of different challenges. In most cases, patients see their physicians when they are not experiencing symptoms or in the middle of an episode. The chemicals released by the mast cells only circulate in the body for a short time, making laboratory diagnosis difficult to obtain.
Treatment of MCAS
The goal of initial treatment for MCAS is two-fold. The immediate goal is to address and improve symptoms and quality of life. Secondly, the initial treatment works as a diagnostic tool.
Common MCAS Comorbidities
Studies on MCAS have found correlations with many other medical conditions. In many cases, it is unclear whether the MCAS predates the other conditions or if the other conditions triggered the MCAS. Some common comorbidities seen with MCAS include:
MCAS and Long COVID
Many Long COVID patients are also being diagnosed with MCAS. However, it is unknown currently if the SARS-CoV-2 virus triggers mast cell dysfunction or if an underlying mast cell dysfunction contributes to the development of Long COVID.
