Prevalence Rate and Risk Factors of Hypothyroidism in Children with Beta Thalassemia Major in Zhuhai Area / 中国实验血液学杂志

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.

Significance of Platelet Parameters in Children with Kawasaki Disease in Diagnosis and Prognosis / 实用儿科临床杂志

Objective To explore the diagnostic and prognostic significances of platelet parameters changes in Kawasaki disease(KD).Methods The platelet total(PLT),mean platelet volume(MPV),platelet distribution width(PDW)and plateletcrit(PCT)were measured in 23 cases of KD on acute febrile phase and early recovery phase.It was compared with 33 cases suffered from other febrile diseases during the same period and in similar ages.Each KD child should accept the cardiology ultrasonic examination.Results The level of PLT,PCT increased in KD patients.It was more significant in early recover period than in acute febrile period(P0.05).PLT negatively correlated with MPV,PDW(r=0.358,0.268 Pa0.05).Conclusions The changes of platelet parameter play a very important role in diagnosis of KD.But it still can not be certain that whether the changes can help us estimate the variety of the patients condition and prognosis of KD children.It requires further study.
