RESUMEN
OBJECTIVE:To investigate the clinical characteristics and rules of allergic reaction caused by anti-copper treat-ment with Sodium dimercaptoproane sulfonate(DMPS)injection,and to provide reference for diagnosis,treatment and monitoring of drug-induced allergic reaction. METHODS:By using retrospective analysis,allergic reaction reports of DMPS injection were se-lected from our hospital during Jan. 2013-Dec. 2015 were analyzed statistically. RESULTS:A total of 131 cases of allergic reaction were reported. The average age of the patients was(23.26±9.63)years old,mainly concentrated on 10-39 years old(87.79%). Al-lergic reaction mainly occurred in the first and second courses of treatment,accounting for 71.76%. For systems-organs involved, skin and its appendages disorders had the highest proportion (85.90%),being mainly the lesion of limbs (27.45%) and body (22.22%) involved;followed by systemic damage (12.33%). Clinical manifestations of systemic impairment were mainly fever, with rash or itching at the same time frequently. 131 patients had good outcome after treatment. The symptoms of 115 patients (87.79%)disappeared in 7 d. Serious cases accounted for 25.19%. The proportion of drug allergy history,the rate of anti-copper treatment failure with allergy prevention or desensitization therapy,and symptom duration in patients with severe ADR were higher or longer than that in general ADR cases,the difference was statistically significant(P<0.05). CONCLUSIONS:The allergic reac-tion of DMPS injection increased the difficulty of anti-copper treatment. ADR monitoring should be strengthened in the process of using DMPS,specially for the history of allergies and the first,second treatment courses of patients.
