Assumptions of the study: Turner syndrome is a rare congenital disorder, one of the characteristic clinical features of which is primary hypogonadism, for which hormone replacement therapy is indicated, continuing at least until the physiological age of menopause. Aim of the study: Evaluate the safety and effect on metabolic and bone parameters of estradiol valerate and dienogest therapy in patients with Turner syndrome. Materials and methods: Anthropometric data and data relating to lipid and carbohydrate profiles and associated pathologies were collected from a sample of 21 patients who had reached puberty. The parameters were measured from the moment of admission to the Endocrinology Unit of the University Hospital of Padua (T0), after 12 months (T1), after 24 months (T2), and at the last follow-up (T3). All patients were evaluated with lumbar and femoral bone densitometry at baseline, and some also at follow-up at least 24 months later. Quantitative measurements were reported as medians and interquartile ranges [IQR]. Paired data were compared using a signed Wilcoxon rank test; a Bonferroni correction was applied in the case of multiple comparisons. The significance threshold was set at p<0.05. Results: Of the patients studied, 57% had X chromosome monosomy, while the remaining 43% had various types of mosaicism involving the sex chromosomes. After a median follow-up of 6 years, no statistically significant changes were found in weight, blood pressure, or metabolic profile parameters, and no patients developed insulin resistance, significant transaminase abnormalities, or thromboembolic events. Densitometry values in the femoral and lumbar regions were also substantially stable. Of the 21 initial patients, 7 (33%) discontinued treatment during follow-up (median treatment duration 5 years) for various reasons, the most common of which was unsatisfactory control of bleeding. Conclusions: This study has demonstrated, for the first time, the safety and neutral effect on anthropometric, metabolic, and densitometric parameters of hormone replacement therapy based on estradiol valerate and dienogest in patients with Turner syndrome.
Presupposti dello studio: La sindrome di Turner è una patologia congenita rara, di cui uno dei tratti clinici caratteristici è la presenza di un ipogonadismo primario, per il quale è indicata la terapia ormonale sostitutiva protratta almeno fino all’età fisiologica della menopausa. Scopo dello studio: Valutare la sicurezza e l’effetto sui parametri metabolici ed ossei della terapia con estradiolo valerato e dienogest nelle pazienti con sindrome di Turner. Materiali e metodi: Sono stati raccolti i dati antropometrici e relativi al profilo lipidico, glucidico e delle patologie associate in un campione di 21 pazienti a pubertà avviata. I parametri sono stati misurati a partire dal momento della presa in carico presso la UOC di Endocrinologia dell’Azienda Ospedale Università di Padova (T0), dopo 12 mesi (T1), dopo 24 mesi (T2) e all’ultimo follow-up (T3). Tutte le pazienti sono state valutate con densitometria ossea lombare e femorale al basale e alcune anche in follow-up ad almeno 24 mesi di distanza. Le misure quantitative sono state riportate come mediane e range interquartile [IQR]. Il confronto tra dati appaiati è avvenuto per dati quantitativi con un test di Wilcoxon dei ranghi con segno; è stata applicata una correzione secondo Bonferroni in caso di confronti multipli. La soglia di significatività è stata settata a p<0.05. Risultati: Delle pazienti oggetto di studio, il 57% presenta monosomia del cromosoma X, mentre le restanti 43% presentano mosaicismi di vario tipo coinvolgenti i cromosomi sessuali. Dopo un follow-up mediano di 6 anni, non sono state riscontrate variazioni statisticamente significative nel peso, nella pressione arteriosa e nei parametri relativi al profilo metabolico, nessuna paziente ha sviluppato insulinoresistenza, alterazione significativa delle transaminasi, o eventi tromboembolici. Anche i valori della densitometria, nei distretti femorale e lombare, sono risultati sostanzialmente stabili. Delle 21 pazienti iniziali, 7 (33%) hanno sospeso il trattamento in corso di follow-up (durata mediana del trattamento 5 anni) per vari motivi, dei quali il più ricorrente è il non soddisfacente controllo dei sanguinamenti. Conclusioni: Attraverso questo studio è stata evidenziata, per la prima volta, la sicurezza e l’effetto neutro sui parametri antropometrici, metabolici e densitometrici della terapia ormonale sostitutiva a base di estradiolo valerato e dienogest nelle pazienti con sindrome di Turner.
