Studio della funzionalità respiratoria in soggetti con sindrome di Turner

The aim of this study is to evaluate the pulmonary function in subjects with diagnosis of Turner Syndrome, in charge at the Syndromology Ward of the Paediatric Clinic of S.Orsola-Malpighi hospital. There are very few datas about lung function in patients with Turner syndrome's genotype and phenotype in medical literature. Since the thorax of these subjects have peculiar anatomic shape (as “shield” or “overturned triangle”), we presupposed that these subjects could have also a peculiar respiratory function. Moreover we look for the possibility of correlation between pulmonary function and estroprogestinic replacement therapy and/or growth hormone (GH) replacement therapy. Material and methods: we studied 48 patients, with diagnosis of Turner Syndrome; they all made spirometry voluntarily and, when capable, also plethismografy. Results: - the parametres of pulmonary function are a little higher of the predicted values for age and sex but they are a little lower if they're corrected for each patient's ideal high and weight: so we can conclude that in Turner Syndrme subjects pulmonary function is normal; -there's not a statistically significant correlation between pulmonary function and GH therapy; -there's not a statistically significant correlation between GH therapy's length and pulmonary function except for Total Lung Capacity which increases with the number of years of GH therapy; - there's not a statistically significant correlation between pulmonary function and estroprogestinic replacement herapy.
