ABSTRACT
Objective To investigate the application value of ELISA for detecting the serum anti desmoglein (Dsg) 1 and Dsg 3 in the diagnosis and treatment of pemphigus .Methods Forty‐seven patients with pemphigus in our hospital from January to De‐cember 2014 were selected as the observation group and contemporaneous 52 patients with excluding pemphigus were selected as the control group .The Dsg antibodies were detected by using indirect immunofluorescence method and Dsg 1 and Dsg3 were deter‐mined by ELISA ;their correlation with pemphigus characteristics was analyzed .Results The sensitivity and specificity of ELISA for detecting anti‐Dsg antibodies were 95 .74% and 92 .31% respectively ,while which of IIF were 93 .62% and 86 .54% respective‐ly ,showing no statistically significant difference between the two test methods (P>0 .05) .In 30 cases of pemphigus vulgaris ,16 ca‐ses (16/30) were positive Dsg1 and Dsg 3 ,8 cases of pemphigus erythematosus and 5 cases pemphigus foliaceus were positive Dsg1 only ,and 2 cases of pemphigus vegetans were both positive Dsgl and Dsg3 .The Dsgl and Dsg3 titers of pemphigus vulgaris and pemphigus vegetans were 130 .85 ± 86 and 112 .30 ± 85 .05 ,respectively ,and the disease activity score was (5 .10 ± 1 .86) points ,the correlation coefficient(r)=0 .476(P=0 .008) ,r=0 .816(P=0 .001) ,respectively .The Dsgl titer of pemphigus erythematosus and pemphigus foliaceus were 142 .59 ± 78 .52 ,and the disease activity score was (2 .77 ± 0 .92) points(r=0 .800 ,P=0 .001) .Conclu‐sion ELISA for detecting Dsg1 and Dsg3 has high sensitivity and specificity ,and is conducive to the diagnosis of pemphigus and e‐valuation of disease severity .
