Comparison Study of Psoriasis Severity Assessment Tools
- Registration Number
- NCT02655705
- Lead Sponsor
- Seoul National University Hospital
- Brief Summary
This study evaluates the performance of objective psoriasis severity assessment tool compared with a subjective assessment tool for the assessment of the improvement of psoriasis after oral cyclosporine A or methotrexate treatment.
- Detailed Description
Patients with moderate-to-severe psoriasis were randomly assigned to treatment for 16 weeks with either cyclosporine A (20 patients; male 200 mg/day, female 150 mg/day) or methotrexate (20 patients; initial dose with 10 mg/week, increased up to 15 mg/week). The primary outcome was to compare the difference between the conventional subjective Psoriasis Area and Severity Index (PASI) and the objective PASI by using Colorimeter at 2, 4, 8, 12, and 16 weeks of treatment. The secondary outcome was differences between cyclosporine and methotrexate for treatment of psoriasis, evaluating clinical efficacy and side effects.

Group Intervention Description Cyclosporine A Cyclosporine A Cyclosporine 200 mg/day (male) and 150 mg/day (female) orally, divided twice daily for 16 weeks Methotrexate Methotrexate Methotrexate was started with 10 mg/week orally as a single dose, increasing 2.5 mg every 2 weeks up to 15 mg/week maintenance dose
- Primary Outcome Measures
Name Time Method Psoriasis Area and Severity Index (PASI) and Objective PASI (oPASI) change over time up to 16 weeks PASI scores and oPASI scores are carried out on every visit. One dermatologist rates a PASI score. A oPASI score is obtained from oPASI formula using Colorimeter parameters L\*, a\* and b\* values.
oPASI = 0.1×oPSI (head)×Area (head) + 0.3×oPSI (trunk)×Area (trunk) +0.2×oPSI (arm)×Area (arm) + 0.4×oPSI (leg)×Area (leg)
oPSI = 0.05 x L\* - 2.5 x tan-1 (b\*/a\*) + 5
PASI range is 0 to 72 score. oPSI range is 1.073 to 10 score.
- Secondary Outcome Measures
Name Time Method Number of participants with abnormal laboratory values and/or adverse events that are related to treatment Screening, 4, and 12 weeks Laboratory tests are performed at screening, 4, and 12 weeks. Patients are checked hemoglobin, hematocrit, white blood cell, platelet, aspartate aminotransferase, alanine aminotransferase, blood urea nitrogen, creatinine, c-reactive protein, and erythrocyte sedimentation. All patients are asked treatment-related adverse events on every visit.
Proportion of patients achieving 75% and 90% PASI improvement on every visit up to 16 weeks Investigators evaluate proportions of patients showing at least 75% and 90% improvement from baseline in PASI.
