Summary

This study follows 5,000 people with common inflammatory skin conditions—like eczema, psoriasis, and hidradenitis suppurativa—over up to 17 years to see how their disease severity changes. Researchers will collect medical history, treatments, and symptom scores to identify factors that lead to better or worse outcomes. The goal is to understand the natural course of these diseases and what predicts a severe or mild future.
