Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
PPP and GPP
Palmoplantar pustulosis (PPP) and Generalized pustular psoriasis (GPP) are rare chronic inflammatory skin diseases, characterized by repeated episodes of sterile pustules in several months or years, associated with erythrokeratodermia generally. Both two diseases are easy to cause skin rupture, leading to bleeding and pain.
