In addition to visible symptoms, people with psoriasis may suffer from poor self-image and social isolation, and even feelings of depression, such as sadness and despair. PASI may be calculated before and after a treatment period to determine efficacy; for example, a PASI 75 correlates to a 75 percent improvement in signs and symptoms of psoriasis. The cytokine network model proposes activation of immunocytes by, for example, infections, medications and trauma, triggering a cascade of cytokines, chemokines and growth factors (Nickoloff 1999). There was a strong correlation between the percentage change in DLQI from baseline to week 10 and the PASI scores (Feldman et al 2005). Biologic systemic therapy for moderate-to-severe psoriasis: A review.

Psoriasis is a long-lasting autoimmune disease characterized by patches of abnormal skin. Diagnosis is typically based on the signs and symptoms. PASI assesses the severity of lesions and the area affected and combines these two factors into a single score from 0 (no disease) to 72 (maximal disease). PUVA is highly effective in the treatment of psoriasis with resolution of skin lesions in over 85 of patients after 20 to 30 treatments combining drug use and ultraviolet A irradiation. 3 mg/kg or more per week, intravenous Emab produced significant clinical and histological improvement in psoriasis, which correlated with sustained serum Emab levels and T-cell CD11a saturation and down-modulation. Patients treated with apremilast showed improvement in signs and symptoms of psoriatic arthritis, including tender and swollen joints and physical function, compared to placebo. Skin and nail signs of psoriasis were assessed using the psoriasis area and severity index (PASI) and nail psoriasis severity index (NAPSI), respectively. Infliximab is effective in both an induction and maintenance regimen for the treatment of moderate-to-severe psoriasis, with a high percentage of patients achieving sustained PASI 75 and PASI 90 improvement through 1 year.

PASI correlates to the physician’s assessment of psoriasis symptoms including redness of lesions, thickness of lesions, scaliness of lesions and extent of disease. Each parameter is graded from 0-4, 0 refers to no disease and 4 to severe involvement. The dermatology-specific DLQI was highly correlated to clinical endpoints at baseline and at Week 12, and was the most responsive PRO to changes in endpoints. HRQoL correlate with improvements in clinical manifestations of the disease.


Sample Closet. Correlation coefficients were calculated at baseline, week 12, and change from baseline to week 12 between the PSD weekly itching, pain, and scaling scores and the PASI and IGA mod 2011 scores. The study also showed that percent change in PASI score was a significant predictor of PSA response. PASI 90 provides greater symptom response as measured by the PSD than PASI 75, concluded the researchers. 3 of the signs (erythema, scaling, and plaque elevation) was significantly higher for DFD-01 than AugBD at day 4 and 15 (P. Overexpression of IL-12 and IL-23 has been documented in psoriasis lesions, and the levels of these cytokines may correlate with disease severity. IL-18 in patients with active psoriasis and correlation with disease severity.
