Summary

Story summary

Researchers aim to identify early markers for psoriatic arthritis (PsA) to prevent joint damage after psoriasis onset.
Key biomarkers include HLA-B27 and high-sensitivity C-reactive protein (CRP), indicating PsA risk levels.
The PRESTO tool assesses clinical features to predict PsA risk over one to five years, with moderate accuracy.
Obesity is a significant risk factor.
Psoriasis treatments may reduce PsA incidence by enabling earlier intervention.
