The age, mean age of disease onset, psoriasis area and severity index (PASI) score and number of tryptase-positive mast cells in the upper dermis in Köbner-positive and -negative groups of psoriatic patients
| Tryptase-positive mast cells at different time-points (cells/mm2) | ||||||||
|---|---|---|---|---|---|---|---|---|
| Age | Age of onset | PASI score | 0 days | 2 h | 1 day | 3 days | 7 days | |
| Köbner-positive (n = 8) | 46 ± 15 | 25 ± 14 | 8·3 ± 4·4 | 149 ± 85 (n = 8) | 157 ± 75 (n = 5) | 161 ± 141 (n = 3) | 95 ± 47 (n = 5) | 127 ± 13 (n = 3) |
| Köbner-negative (n = 10) | 54 ± 15 | 40 ± 17 | 6·7 ± 5·0 | 145 ± 122 (n = 10) | 173 ± 59 (n = 4) | 107 ± 49 (n = 6) | 97 ± 13 (n = 3) | 107 ± 36 (n = 6) |
The results are expressed as the mean ± standard deviation. Statistically no significant changes were observed within or between Köbner groups (paired and unpaired t-test).
