ABSTRACT
Objective To investigate the clinical manifestations,diagnosis,treatment,and laboratory examination characteristics of 8 pemphigus patients with high titers of anti-desmoglein antibodies in remission. Methods A retrospective study was conducted for the pemphigus patients diagnosed and treated in the department of dermatology from January 2013 to September 2020.The patients should have the serum anti-desmoglein antibodies ≥150 U/ml in remission or the antibody levels dropped less than 20%(calculated based on the maximum detection limit of 150 U/ml)of their initial ones detected before treatment,and the clinical and laboratory data of patients eligible for the inclusion criteria were collected. Results Among the 134 pemphigus patients with available follow-up data during this period,a total of 8 patients met the criteria,with the follow-up period of 21-85 months and the remission duration of 18-70 months.They all received less than or equal to 10 mg/d prednisone and had high titers of anti-desmoglein antibodies.At their first visit,the number of patients with positive anti-desmoglein 1/desmoglein 3 antibodies was 7.Two patients still had high titers of anti-desmoglein 1 antibodies 19 months and 21 months after they achieved remission,and 5 patients had high titers of anti-desmoglein 3 antibodies in 18-70 months.There was one patient showing high titers of both antibodies,especially for anti-desmoglein 1 antibodies.This patient relapsed after 19 months' remission while other patients were still in clinical remission. Conclusions Some pemphigus patients showed persistent high titers of anti-desmoglein antibodies in remission.Anti-desmoglein 3 antibodies were more common to keep positive,while high titer of anti-desmoglein 1 antibodies was less observed.The high titer of anti-desmoglein 1 antibodies had a correlation with recurrence.For the pemphigus patients with long-term clinical remission but high antibody titer,the dosages of corticosteroids should be adjusted carefully according to their actual clinical manifestations and the positive antibody type.For the patients with high titer of anti-desmoglein 1 antibodies,the dosage reduction of corticosteroids should be appropriately slower.
