چکیده

Objective Patients with Turner syndrome (TS) are at increased risk for metabolic disorders. We aimed to delineate the occurrence and evolution of metabolic comorbidities in TS patients and to determine whether these differ in 45,X monosomy and other karyotypes. Methods A longitudinal and cross-sectional retrospective cohort study was conducted in a tertiary pediatric endocrine unit during 1980-2016. Ninety-eight TS patients, 30 with 45,X monosomy were followed from childhood to early adulthood. Outcome measures included weight status, blood pressure (BP), glucose metabolism, and lipid profile. Results Longitudinal analysis showed a significant change in body mass index (BMI) percentiles over time [F(3,115) = 4.8, P = 0.003]. Age was associated with evolution of elevated BP [systolic BP: odds ratio (OR) = 0.91, P = 0.003; diastolic BP: OR = 0.93, P = 0.023], impaired glucose metabolism (HbA1c: OR = 1.08, P = 0.029; impaired glucose tolerance: OR = 1.12, P = 0.029), and abnormal lipid profile (cholesterol: OR = 1.06, P = 0.01; low-density lipoprotein cholesterol: OR = 1.07, P = 0.041; high-density lipoprotein cholesterol: OR = 1.07, P = 0.033). The occurrence of metabolic comorbidities was similar in 45,X monosomy and other karyotypes. Coexistence of multiple metabolic comorbidities was significantly higher in 45,X monosomy [F(1,72) = 4.81, P = 0.032]. BMI percentiles were positively correlated with metabolic comorbidities (occurrence and number) in each patient (r = 0.35, P = 0.002 and r = 0.383, P = 0.001, respectively). Conclusion Our longitudinal study provides unique insights into the evolution of weight gain and metabolic disorders from childhood to early adulthood in TS patients. Since overweight and increasing age aggravate the risk for metabolic comorbidities, careful surveillance is warranted to prevent and control obesity already from childhood. The more prominent clustering of metabolic comorbidities in 45,X monosomy underscores the importance of a more vigorous intervention in this group.

Turner Syndrome: A Unique Mosaic Case with 45,X/47,XX,+21/46,XX Cell Lines

We report an extremely rare case of Turner syndrome mosaicism in a 30-year-old woman. At least 100 metaphases were observed and analyzed through GTG banding with over 550 band resolutions observed. G-banded chromosome analysis revealed a mosaic female karyotype involving 3 different cell lines. One cell line (90% of the analyzed metaphases) presented monosomy X, while 6% of the cells showed tri...

Comparison of classical cytogenetics versus interphase FISH in diagnosis of mosaic form of Turner syndrome

 Abstract  Background: Mosaic form of turner syndrome that represented by two or more  cell lines in an affected individual, often has limitation for detection with classical  cytogenetic methods. The present study was carried out to compare the efficiency of  interphase Fluorescence In Situ Hybridisation (FISH) and cytogenetic techniques in  detection of mosaic form of turner syndrome.  Method...

Prevalence of cardiovascular malformations and association with karyotypes in Turner's syndrome.

The aim of the study was to establish the prevalence of cardiovascular malformations in females with Turner's syndrome and analyse possible associations with the various karyotypes. One hundred and seventy nine of 393 females who had Turner's syndrome diagnosed in Denmark were examined. Complete chromosome analysis was available in all cases.

Turner syndrome isochromosome karyotype correlates with decreased dental crown width.

The aim of this project was to study possible influences of Turner syndrome (TS) karyotype and the number of X chromosomes with intact short arm (p-arm) on dental crown width. Primary and permanent mesio-distal crown width was measured on plaster casts from 112 TS females. The influence on crown width of four karyotypes: 1. monosomy (45,X), 2. mosaic (45,X/46,XX), 3. isochromosome, and 4. other...
