Abstract:
OBJECTIVE:To investigate the prevalence rate of hypothyroidism in children with β-thalassemia major (β-TM) and its risk factors.
METHODS:A total of 86 children with β-TM treated and followed up in the Department of Pediatrics of the Fifth Affiliated Hospital of Sun Yat-Sen University, Zhuhai Municipal Maternal and Child Health Care Hospital from August 2018 to August 2020 were enrolled. The clinical data of the children were analyzed to investigate the prevalence rate of hypothyroidism in children with β-thalassemia major (β-TM) and its risk factors.
RESULTS:The prevalence rate of hypothyroidism in children with β-TM in Zhuhai area was 17.4%. The level of serum ferritin(SF) (4948.27±1225.33 μg/L) in hypothyroidism children was significantly increased(t=10.273，P<0.05). The prevalence rate of hypothyroidism was significantly higher in β-TM children(age ≥10 years old, SF ≥2 500 μg/L and irregular iron removal) (P<0.05). Logistic regression result showed that age ≥10 years old was the independent risk factor affecting the increasing of hypothyroidism rate in the children. The levels of SF(3880.60±1269.17 μg/L), TSH(4.43±1.52 mIU/L) and the prevalence rate of hypothyroidism(37.14%)(P<0.05) were higher for the children in irregular iron removal group.
CONCLUSION:The prevalence rate of hypothyroidism in children with β-TM in Zhuhai area is high, and it is related to the age ≥10 years old, SF ≥2 500 μg/L and irregular iron removal of the children.
