Matched Pre- and Post-Therapeutic Plasma Exchange Soluble Mesothelin Levels. Soluble mesothelin (sMSLN) levels were evaluated in 15 patients before and after one plasma volume of therapeutic plasma exchange (TPE). After TPE, sMSLN levels were consistently reduced (p = 0.031) with an average decrease of 43.6% or 15.4 ng/mL.
