pemphigus vulgaris activity score and assessment of convergent validity.

چکیده
pemphigus is a rare autoimmune blistering disease with different phenotypes. the evaluation of therapeutic interventions requires a reliable, valid and feasible to use measurement. however, there is no gold standard to measure the disease activity in clinical trials. in this study we aimed to introduce the pemphigus vulgaris activity score (pvas) measurement and to assess the convergent validity with the experts' opinion of disease activity. in pvas scoring, the distribution of pemphigus vulgaris antigen expression in different anatomical regions is taking in to account with special consideration of the healing process. pvas is a 0-18 scale, based on the extent of mucocutaneous involvement, type of lesion and the presence of nikolsky's sign. the sum of the scores of total number of lesions, number of different anatomic regions involvement and nikolsky's sign is weighted by the type of lesion. in the present study, pvas was assessed in 50 patients diagnosed with pemphigus vulgaris by one dermatologist. independently, five blinded experts scored all the patients through physician's global assessment (pga). the convergent validity with experts' opinion was assessed. the spearman coefficient of correlation showed the acceptable value of 0.751 (95%ci: 0.534- 0.876). pvas is a valid, objective and simple-to-use scoring measurement. it showed a good correlation with pga of pemphigus disease activity in iranian patients with pemphigus vulgaris.

INTRODUCTION Pemphigus vulgaris (PV) is a chronic, autoimmune, vesiculobullous disease.

This also precludes conduct of a meta-analysis. METHODS English-language publications describing treatment ...
متن کاملcorrelation of pemphigus vulgaris antibody titers by indirect immunofluorescence with activity of disease based on pemphigus area and activity score (paas)
indirect immunofluorescence (iif) has been used to identify and measure autoantibody levels in pemphigus vulgaris but data about relationship between clinical severity of disease and antibody titers by iif have been conflicting. we conducted this cross-sectional study to correlate the severity of oral and/or cutaneous involvement in patients with pemphigus vulgaris based on pemphigus area and a...
