Popis: | Background: Individuals with Down syndrome (DS) are at an increased risk of developing thyroid disease, primarily autoimmune, with a lifetime prevalence ranging from 13% to 63%. Unfortunately, there are few studies systematically examining the frequency of thyroid disease in very young children. Aim of the study: The aim of the present study was to investigate the prevalence of different thyroid dysfunctions (TD) in a cohort of infants and children with DS and the growth parameters in subjects with normal versus abnormal thyroid function, followed for 3 years. Patients and methods: All children (n = 102; 48 males and 54 females, aged 2.3±3 years) with the diagnosis of DS who were seen at the General Pediatric Clinic of Hamad General Hospital in Doha (Qatar) from 2014 to 2018 were enrolled in our study. We recorded thyroid function and linear growth parameters [BMI, length/height SDS (Ht-SDS) and weight gain/day] and divided them into 3 groups according to their thyroid function. Group 1: (n = 36 subjects) with normal free T4 (FT4) and TSH; Group 2 (n = 44 subjects) with high TSH >5 and 12 mIU/L and/or FT4 1 year; n=55; mean age: 5.5±3.3 years) primary HT was detected in 7/55 (12.7%). Subclinical HT was diagnosed in 20/55 (36.4%) and positive thyroid antibodies were found in 26/55 (47.3%). Before treatment with L-thyroxine, using the CDC growth charts for DS, we found that the groups with high TSH (Groups 2 and 3) were significantly shorter and heavier compared to the group with normal TSH (Group 1). After treatment with L-thyroxine, the Ht-SDS and Wt-SDS did not differ between the two groups. The linear growth of those diagnosed early during the first year of life was compared to growth parameters of children who were diagnosed with thyroid dysfunction later in life. Conclusion: Our data provided more evidence to support the findings that L- thyroxine treatment can improve growth of infants and young DS children with high TSH (>5 mIU/L), especially in those with TSH >12 mIU/L.
