To monitor inflammation and infection, the levels of several biomarkers, such as C-reactive protein (CRP), procalcitonin (PCT), and interleukin-6 (IL-6), appear to be associated with the presence of inflammatory processes and the severity of CS, not only in plasma but also in serous body fluids such as pulmonary edema [3]. The gene discussed is IL6; the disease is Cowden syndrome 1.
