This week we’ve invited Dr. Lauren Henderson of Boston Children’s Hospital to discuss what Macrophage Activation Syndrome (MAS) is, how to diagnose it and which medications are used to treat it. Dr. Henderson also explains her efforts to partner with healthcare professionals in other fields (who may use a different name for MAS) seeking to understand what treatments they use when confronted with MAS and to establish a formalized process in evaluating and treating these patients together.
