Initial studied about role of anti ANA and dsDNA on the patients of scleroderma

ABSTRACT

42 patients were diagnosed as scleroderma and treated at Bach Mai Hospital in three years (1991-1993). 90.47% was female, the age ranged from 18 to 63 years. The control group consisted of 20 healthy normal persons. Results: the rate of anti dsDNA positive with serum 1/10 was 30.95%; the rate of anti ANA positive with serum 1/40 was 71.42% in the patients with scleroderma. In the control group, there is no person who had anti dsDNA positive with serum 1/10. The rate of anti ANA positive with serum 1/40 is 10%. Positive anti dsDNA rate is not high (30.95%). There is no case of scleroderma which had negative anti ANA but positive anti dsDNA in the patients group. The appearance of anti dsDNA and anti ANA with digestive and cardiovascular disorder had a high rate. Anti ANA is more valuable in following the nephroinjuries in the scleroderma than dsDNA
