Clinical care of adult Turner syndrome--new aspects.

Turner syndrome (TS) is characterized by numerous medical challenges during adolescence and adulthood. Puberty has to be induced in most cases, and female sex hormone replacement therapy (HRT) should continue during adult years. These issues are normally dealt with by the paediatrician, but once a TS female enters adulthood it is less clear who should be the primary care giver. Morbidity and mortality is increased, especially due to the risk of dissection of the aorta and other cardiovascular diseases, as well as the risk of type 2 diabetes, hypertension, osteoporosis, thyroid disease and other diseases. The proper dose of HRT with female sex steroids has not been established, and, likewise, benefits and/or drawbacks from HRT have not been thoroughly evaluated. The transition period from paediatric to adult care seems to be especially vulnerable and the proper framework for transition has not yet been established. Likewise, no framework is in place for continuous follow-up during adult years in many countries. Today, most treatment recommendations are based on expert opinion and are unfortunately not evidence based, although more areas, such as growth hormone and oxandrolone treatment for increasing height, are becoming well founded. Osteoporosis, diabetes, both type 1 and 2, hypothyroidism, obesity and a host of other endocrine diseases and conditions are seen more frequently in TS. Prevention, intervention and proper treatment is only just being recognized. Hypertension is frequent and can be a forerunner of cardiovascular disease. The description of adult life with TS has been broadened and medical, social and psychological aspects are being added at a compelling pace. Proper care during adulthood should be studied and a framework for care should be in place, since most morbidity potentially is amenable to intervention. In summary, TS is a condition associated with a number of diseases and conditions which need the attention of a multi-disciplinary team during adulthood.
