Introduction: The influence of growth hormone (GH) treatment on amino acids (AAs) profile in patients with Turner syndrome (TS) was investigated.
Material and methods: The study group included girls with TS: treated with GH (GH+) and girls with no GH treatment (GH-). The control group consisted of healthy girls. Free plasma AAs were measured by the LC/MS/MS.
Results: The plasma concentrations of glutamine, threonine were significantly higher in group GH+ than in group GH- (p < 0.05). In group GH- the values of glutamine, alanine, isoleucine, glutamic acid were significantly different than in the control (p < 0.05-p < 0.008).
Conclusion: AAs profile in girls with TS might be characteristic for the disease but also depends on GH treatment.
