CRP and psoriasis: Furthermore, a study concluded that cases with moderate-to-severe plaque-type psoriasis had active systemic inflammation, which was demonstrated by increased CRP, and its values were correlated with skin disease severity, while another study highlighted that CRP may be considered as a useful marker of psoriasis severity, which could also be used to monitor psoriasis and its treatment; psoriatic arthritis can also show elevated hsCRP, as seen in various studies, yet further data about its utility as a biomarker in this condition are limited [717,718,719].
