Results

Seventeen AD patients were assigned randomly. Four patients dropped out of. The eruption area and SCORAD score were significantly decreased in theCTP group. TEWL levels were improved in the CTP group. Skin hydration tended to elevate, but did not reach statistical significant.In blood samples, a significantly reduction in the TARC level was seen only CTP group. The levels of serum LDH and IgE were not changed in either group. In the control group, eosinophil counts were increased compared to baseline.

Baseline Characteristics

Atopic dermatitis patients with mild to moderate disease.

Participant flow

Patients were allowed to use their daily topical products, except on one upper arm.
Eligible patients were assigned randomly under double-blind conditions to receive either a CTP product or normal collagen which does not contain CTP.
Peptides were administered orally for 12 weeks.
