Hyperlipidemia and presence of thyroid autoantibodies in girls with Turner's syndrome or mosaic variance.

OBJECTIVE

The investigation of differences in the medical status between girls with Turner's syndrome or mosaic variance and healthy girls of the same age. In addition, the existence of differences between those persons with full Turner's syndrome and those with mosaic variance were examined. The influence of the treatment was also of concern because a number of the subjects in the study group were being treated with hormones (estrogen and progestin). Investigation concerned cardiovascular abnormalities, bone age, and lipid and hormonal profiles of the participating persons.

PARTICIPANTS

Girls came to the hospital with problems in their menstrual cycles. Genetic control (karyotyping) took place. Each patient with symptoms of Turner's syndrome or mosaic variance was included in the study group. Every third patient with no symptoms of the syndromes and near the same age were included in the control group.

METHODS

Stratification was made according to the body mass index of the participating persons. Nonparametric tests were used for the analysis.

RESULTS

Differences were detected in the levels of cholesterol, low-density lipoproteins (LDLs), high-density lipoproteins (HDLs), and triglycerides, and were increased in the study group. Presence of thyroid autoantibodies, antithyreo-globulin-antibodies (AASTs) and antimicrosomatic antibodies (AASMs), was observed in the study group. In addition, differences were observed in HDL levels between persons with full Turner's syndrome and those with mosaic variance. Finally, significant difference was observed in the level of triglycerides and in the presence of AASTs and AASMs in treated and untreated persons with mosaic variance.

CONCLUSIONS

Metabolic, genetic, eating or autoimmune mechanisms are suspected.
