Levonorgestrel correlates with less weight gain than other progestins during hormonal replacement therapy in Turner Syndrome patients.

Turner Syndrome (TS) is associated with an increased risk of cardiovascular and metabolic complications. Furthermore, TS women need hormone replacement therapy (HRT), of which progestins can influence body weight. We aimed to analyze the metabolic and weight profile in a cohort of 111 TS women. They started receiving estrogen at 15.8 (±3.6) years old, with no change in hypertension, dysglycemia, and dyslipidemia incidence but with a tendency to increase overweight (p = 0.054). As the first used type of progestin, most had received cycles of 10 days per month of medroxyprogesterone (MPA) or levonorgestrel (LNG), then shifted to micronized progesterone (MP), which has currently become the most used one. By multiple linear regression analysis, we found that the prolonged use of MPA, LNG, or MP showed no metabolic change except for weight gain. The percentage of annual BMI increment was positive for all progestins used in TS women (MPA 2.2 ± 2.2; LNG 0.2 ± 1.2; and MP 2.2 ± 2.6 kg/m2), but LNG seemed to best prevent on weight gain over time (p < 0.05). In conclusion, metabolic comorbidities are prevalent in TS even before the HRT regimen, and LNG performed better on less weight gain than MPA and MP in our cohort of the TS population.

Stylohyoid Ligament Calcification: A Greater-Than-Expected Cause of Otalgia in Turner Syndrome.

CONTEXT: Otitis is common in patients with Turner syndrome (TS) and may be misdiagnosed in the presence of other causes of otalgia. OBJECTIVE: We hypothesized that stylohyoid ligament calcification (SLC), named Eagle syndrome (ES), is a common cause of otalgia in TS. DESIGN: Cohort of 1-year data collection. SETTING: We analyzed all consecutive women with Turner syndrome (TW). PATIENTS: Ninety-six TW and 55 age-paired normal control women (CW). INTERVENTION: Participants were asked about current or past otalgia and had bilateral tonsillar palatine palpated by the same physician. MAIN OUTCOME MEASURES: When otalgia or cervicalgia plus painful palatine tonsil palpation was positive, participants underwent facial X-ray or three-dimensional cranial CT. If SLC was >25 mm, ES was confirmed. RESULTS: Thirty-four TW (35%) had clinical signs and 27/34 (79%) had radiologically confirmed ES. Of the TW with confirmed ES (27/96; 28%), 14 (51.9%) were inadvertently treated for recurrent otitis as a presumed cause of otalgia. Eleven of the TW with ES (26.1%) were below age 21. There was no association with karyotype, age, body mass index, or growth hormone use. Ten CW (18.2%) complained of symptoms of ES, but only 4 (7.3%) were radiologically confirmed (CW vs TW, P < 0.01), and none were <21 years old. ES occurred more at younger ages in TW (P < 0.002). CONCLUSION: ES is more prevalent in TW than in controls and occurs at younger ages. ES must be assessed as a common comorbidity of TS at any age, especially during childhood, as a differential diagnosis of otalgia.
