Abstract: Objective To investigate the clinical manifestations, latency, ADR monitoring,and treatment of adverse reactions related to anti-thyroid drugs(ATD)and the clinical effect of 131 I replacement therapy so as to provide individualized treatment for patients with hyperthyroidism and reference for safer ATD treatment. Methods The clinical data on 119 patients with hyperthyroidism hospitalized due to ADT-induced ADR between June 1, 2017 to May 31, 2019 was retrospectively analyzed. Patients' age, gender, involved organs and systems, types and clinical manifestations of ADR, incubation of ADR, treatments and treatment outcomes were statistically analyzed. The clinical efficacy of 131I in these patients was also evaluated. Results 79% of the patients developed ADR within one month of medication. ADR occurred as shortly as one day after medication manifested by rashes and myalgia and as late as two years after medication, with leucopenia as the symptom. The highest incidence of ADRs was attributed to the hepatobiliary system damage (MMI 52.78%, PTU 66.67%), blood system damage (MMI 30.56%, PTU 41.67%), and skin and accessory system damage (MMI 19.44%,PTU 8.33%). After 131I was applied to these patients, the difference in indicators of serum TSH, T3 and T4 was statistically significant (P<0.05).The effective rate of treatment was as high as 93.2%, and there was some chance of long-term hypothyroidism. Conclusion Drugs should be rationally selected according to the characteristics of different ATD treatments. Blood routine indexes, liver function, thyroid function and other indicators should be checked regularly during the treatment to prevent ADRs and ensure the safe use of drugs for patients. 131I treatment has significant efficacy and is quite safe in patients with hyperthyroidism who develop adverse reactions to ATD treatment.
