Although Graves disease is most common among women in their 20s and childhood-onset cases account for less than 5% of all cases of Graves disease, they account for the majority of hyperthyroidism in children. We report here a retrospective review of data on pediatric patients with Graves' disease who visited our hospital for the first time at the time of their initial examination. Methods We analyzed 21 pediatric patients with Graves disease who visited our hospital between November 2004 and January 2022. The electronic medical records of 21 patients were retrospectively reviewed for sex, age, height SD score, weight SD score, underlying disease, blood test results, and treatment initiation. Results There were 17 girls and 4 boys. The median age was 11 years and 5 months. Symptoms such as fever, feverishness, palpitations, weight loss, hyperactivity, and irritability were observed in 5 of the patients. Four patients had symptoms related to academic performance, such as low grades and poor concentration. Median physical findings were height SD score 0.62 (N=21), weight SD score 0.06 (N=21), and body mass index -4.4%. Two patients had bronchial asthma and atopic dermatitis, and one had myasthenia gravis and trisomy21 as underlying diseases. One patient was considered to have attention deficit hyperactivity disorder and was receiving antipsychotic medication. The median blood test values at the first visit were ALP 857 U/L (N=19), total cholesterol level 122 mg/dL (N=19), fT3 14.31 pg/mL (N=21), fT4 4.60 ng/dL (N=21), thyroid stimulating antibody 668 % (N=7), TSH receptor antibody 16.6 IU/L (N=20 TSH was less than sensitive in all cases. Nineteen patients received thiamazole. Fourteen patients received propranolol. Five patients received inorganic iodine. Five patients received inorganic iodine, starting at a median of 0.926 mg/kg/day of body weight. Discussion As with adults, females were more common. The symptoms were similar to those of attention deficit hyperactivity disorder, and thus warranted attention. Symptoms related to poor academic performance were also considered important. Anti-thyroglobulin antibodies and anti-TPO antibodies were also detected, suggesting that we should be careful about the possibility of the disease progressing to Hashimoto's disease.
