FABP7 and psoriasis: As FABP-7 did not correlate directly with skin lesion severity in general, but was significantly increased in most diseased subjects, we might conclude that psoriasis severity does not influence the risk of NDs in psoriatic patients with the mild or moderate form, but patients with severe psoriasis might be at higher risk of NDs development and FABP-7 might serve as a potential indicator of it.
