Abstract
Background: Children born with a history of Intra-Uterine Growth Retardation (IUGR) may be susceptible for reduced growth velocity and growth deficiency. The causes of GH/IGF-1 resistance are unknown. Klinefelter syndrome is characterized by excessive growth, resulting from hypogonadism, open bone age and a prolonged growth.
Objectives: The case of a 6-year-old boy with Klinefelter syndrome born with IUGR and deep growth deficiency was studied.
A case report: A 6-year-old boy with birth weight 2300 g born of term in 38 Hbd is presented. The cariotype was 47XXY. The phenotype was typical for a child with IUGR. GH in the clonidin test was 37.4 microIU/ml, IGF-1 -- 111 ng/ml. Increased IGF-1 level from 178.1 ng/ml to 360.9 ng/ml was founded in the IGF-1 generation test.
Conclusions: The cause of growth deficiency in this case could be GH/IGF-1 resistance.
