Standardized multidisciplinary evaluation yields significant previously undiagnosed morbidity in adult women with Turner syndrome.

Context: Besides short stature and gonadal dysgenesis, Turner syndrome (TS) is associated with various abnormalities. Adults with TS have a reduced life expectancy, mainly related to structural abnormalities of the heart and aorta, and an increased risk of atherosclerosis.

Objective: Our objective was to investigate the yield of an initial standardized multidisciplinary screening in adult TS patients.

Design And Setting: This was an observational study at a multidisciplinary care unit for adult women with TS.

Participants: Participants were adult women with TS (n = 150). Mean age was 31.0 ± 10.4 yr, with 47% karyotype 45,X.

Interventions: All women were consulted by an endocrinologist, a gynecologist, a cardiologist, an otorhinolaryngologist, and when indicated, a psychologist. The screening included magnetic resonance imaging of the heart and aorta, echocardiography, electrocardiogram, dual-energy x-ray absorptiometry, renal ultrasound, audiogram, and laboratory investigations according to international expert recommendations.

Main Outcome Measures: New diagnoses and prevalence of TS-associated morbidity were evaluated.

Results: Thirty percent of patients currently lacked medical follow-up, and 15% lacked estrogen replacement therapy in the recent last years. The following disorders were newly diagnosed: bicuspid aortic valve (n = 13), coarctation of the aorta (n = 9), elongation of the transverse aortic arch (n = 27), dilation of the aorta (n = 34), osteoporosis (n = 8), osteopenia (n = 56), renal abnormalities (n = 7), subclinical hypothyroidism (n = 33), celiac disease (n = 3), glucose intolerance (n = 12), dyslipidemia (n = 52), hypertension (n = 39), and hearing loss warranting a hearing aid (n = 8). Psychological consultation was needed in 23 cases.

Conclusions: Standardized multidisciplinary evaluation of adult women with TS as advocated by expert opinion is effective and identifies significant morbidity. Girls with TS benefit from a careful transition to ongoing adult medical care.
