RESUMEN

INTRODUCTION: Hypothyroidism is a common disorder, appearing mainly in women although less frequently found in women with polycystic ovary syndrome (PCOS). The objective was to test the hypothesis that hyperandrogenism might protect against hypothyroidism. MATERIAL AND METHODS: The data from three prospective follow-up studies (up to 21 years) and one register study were compared: women with PCOS (Rotterdam criteria), n = 25, women with Turner syndrome, n = 217, a random population sample of women, n = 315, and men, n = 95 (the WHO MONICA study). Findings were to be verified or rejected in all females, n = 553 716, from the same region. The proportion of hypothyroidism was calculated and thyroid peroxidase antibodies (TPO) in serum were measured. RESULTS: Hypothyroidism at >50 years of age was found in 8% of women with PCOS, 4% in men (PCOS vs. men; ns), 43% of women with Turner syndrome, irrespective of karyotype (p < 0.001 vs. PCOS), and in 17% of postmenopausal women in the population (p < 0.01 vs. PCOS). Elevated TPO were similar in PCOS and women and men in the population but higher in Turner syndrome. Hypothyroidism increased with age in all groups except PCOS women and men. In the register study, hypothyroidism was less common in women with PCOS >25 years (5.5%) than in women without PCOS (6.8%) from the same region (p < 0.01). CONCLUSIONS: Hypothyroidism was less frequently seen in women with PCOS and in men compared with women in the general population and among women with Turner syndrome. This was not explained by altered autoimmunity or the Y-chromosome. Androgens seem to protect against hypothyroidism.

RESUMEN

Turner syndrome (TS) is a genetic condition characterized by partial or complete monosomy X. A reduced life expectancy has been shown in TS, depending on an increased risk of aortic dissection, and ischemic heart disease. Studies covering the occurrence of psychiatric conditions are sparse within TS. Several case reports describe concomitant TS and neuropsychiatric abnormalities that may represent a pathogenetic link to genetics, as well as feature correlates of TS. The aim of this study was to determine the presence, and the frequency of psychiatric diagnosis in women with TS in a Swedish cohort followed during 25 years' time. Statistics from the entire female population in Sweden of corresponding age was used as reference. Data were retrieved from clinical examinations and validated from the National Board of Health and Welfare registries for women with TS (n = 487), aged 16 to 84 years, with respect to mental health disorders. The most common diagnoses in TS were mood and anxiety disorders. There was no increase in psychiatric diagnosis within the group with time, nor correlation to specific karyotype or somatic comorbidity as congenital heart disease and hypothyroidism, hormonal treatment, or childbirth. In addition, the frequency of psychiatric diagnosis in TS was lower than in the population-based data. Further investigations are needed in the view of the fact that women with Turner syndrome should not be burdened with more severe diagnoses.

RESUMEN

CONTEXT: Turner syndrome (TS) is the most common chromosomal aberration in women; it is the result of structural or numeric abnormalities in the X chromosome. Autoimmune hypothyroidism has been recognized as one of the more prominent disorders associated with TS. OBJECTIVE: This work aimed to study the prevalence of autoimmune diseases in TS. METHODS: A cross-sectional, longitudinal, 25-year follow-up study was conducted of patients from adult Turner centers at the University Hospitals, Sweden. During 1994 to 2020, a total of 503 women aged 16 to 71 years with TS were evaluated consecutively every fifth year according to national guidelines. A random population sample of women, n = 401, aged 25 to 44 years, from the World Health Organization Monitoring of Trends and Determinants for Cardiovascular Disease (MONICA) project served as controls. Serum thyrotropin, free thyroxine, vitamin B12, antithyroid peroxidase (anti-TPO), and antitransglutaminase antibodies were measured. RESULTS: Mean follow-up time (years) was 16 ± 7 for patients and 13 ± 1 for controls. From study start, the prevalence increased in TS for hypothyroidism 40% to 58%, vitamin B12 deficiency 5% to 12%, celiac disease 4% to 7%, positive anti-TPO 26% to 41%, and antitransglutaminase antibodies 6% to 8% (P < .0001 vs controls). Type 1 diabetes and Addison disease were rare. The only interrelationship was between hypothyroidism and vitamin B12 deficiency, both in TS and controls. No association between autoimmune disease and karyotype, antecedent growth hormone treatment, or ongoing estrogen hormone replacement, was seen in TS. CONCLUSION: In women with TS up to older than 80 years, more than half developed hypothyroidism, mainly autoimmune, during follow-up. Awareness of vitamin B12 deficiency and celiac disease throughout life is also recommended in women with TS.

RESUMEN

STUDY QUESTION: Do women with Turner karyotype have increased mortality and morbidity in the years after childbirth? SUMMARY ANSWER: No mortality occurred during pregnancy and follow-up in women with Turner karyotype, but a higher rate of circulatory and endocrine diseases and a high risk of aortic aneurysm were confirmed. WHAT IS KNOWN ALREADY: Pregnancies in women with Turner karyotype are high-risk pregnancies with an increased risk of maternal mortality from aortic dissection and morbidity from hypertensive disorders. STUDY DESIGN, SIZE, DURATION: A retrospective Swedish population-based registry study of 124 women with Turner karyotype born between 1957 and 1987 and who gave birth between 1973 and 2010. Women with Turner karyotype without childbirth (n = 378) were selected as controls. A second control group consisted of women from the Swedish Medical Birth Register (MBR) (n = 1230) matched for maternal age, number of children and year of birth of the first child. PARTICIPANTS/MATERIALS, SETTING AND METHODS: Women with Turner karyotype were identified in the Swedish Genetic Turner Register. Data were obtained by using the unique personal identification number with cross linkage to the Swedish MBR, the Cause of Death Register, the National Patient Register and the Swedish Cancer Register. Hazard ratio (HR) with 95% confidence interval (CI) was used in the analysis of morbidity. MAIN RESULTS AND THE ROLE OF CHANCE: No mortality occurred in women with Turner karyotype and childbirth. Diseases of the circulatory system occurred more often in women with Turner syndrome under the age of 40 years compared with the MBR control group (HR 4.59; 95% CI 2.75-7.66) but was similar at or above the age of 40 years. Morbidity from circulatory diseases was increased before pregnancy (HR 3.83; 95% CI 1.02-14.43) and during pregnancy or within 1 year after (HR 5.78; 95% CI 1.94-17.24), but was similar after 1 or more years after delivery (HR 1.91; 95% CI 0.74-4.96). Aortic aneurysm occurred in 11/502 (2.2%) women with Turner karyotype and in three women (2.4%) during pregnancy. The long-term follow-up showed that aortic dissection was a common cause of death in young women with Turner karyotype without childbirth. A thorough cardiac evaluation before pregnancy in women with Turner karyotype is of utmost importance. LIMITATIONS, REASONS FOR CAUTION: Although this was a population-based registry study performed over a period of more than 20 years, a much longer follow-up and larger series are needed to assess rare events. The study also lacks information on phenotype and mode of conception in women with Turner karyotype. Women who gave birth probably represent a selection of healthier women with Turner karyotype. WIDER IMPLICATIONS OF THE FINDINGS: The high risk of aortic aneurysm in young women with Turner karyotype is in agreement with the literature.

RESUMEN

BACKGROUND: Women with Turner syndrome (TS) have an increased risk of aortic dissection. The current recommended cutoff to prevent aortic dissection in TS is an aortic size index (ASI) of ≥2.5 cm/m2. This study estimated which aortic size had the best predictive value for the risk of aortic dissection, and whether adjusting for body size improved risk prediction. METHODS: A prospective, observational study in Sweden, of women with TS, n = 400, all evaluated with echocardiography of the aorta and data on medical history for up to 25 years. Receiver operating characteristic (ROC) curves, sensitivity and specificity were calculated for the absolute ascending aortic diameter (AAD), ascending ASI and TS specific z-score. RESULTS: There were 12 patients (3%) with aortic dissection. ROC curves demonstrated that absolute AAD and TS specific z-score were superior to ascending ASI in predicting aortic dissection. The best cutoff for absolute AAD was 3.3 cm and 2.12 for the TS specific z-score, respectively, with a sensitivity of 92% for both. The ascending ASI cutoff of 2.5 cm/m2 had a sensitivity of 17% only. Subgroup analyses in women with an aortic diameter ≥ 3.3 cm could not demonstrate any association between karyotype, aortic coarctation, bicuspid aortic valve, BMI, antihypertensive medication, previous growth hormone therapy or ongoing estrogen replacement treatment and aortic dissection. All models failed to predict a dissection in a pregnant woman. CONCLUSIONS: In Turner syndrome, absolute AAD and TS-specific z-score were more reliable predictors for aortic dissection than ASI. Care should be taken before and during pregnancy.

RESUMEN

STUDY QUESTION: In a transgender population referred for fertility consultation, which factors influence the decision to cryopreserve oocytes and sperm? SUMMARY ANSWER: Previous hormonal treatment, gender affirmation surgery and sexual orientation were associated with the decision to undergo fertility preservation and transgender women underwent fertility preservation more frequently than transgender men. WHAT IS KNOWN ALREADY: It is well-known internationally that fertility preservation and fertility treatment are increasingly requested by transgender men and women. Factors affecting their decisions as well as treatment differences between transgender women and transgender men have been reported, but many studies have had low participation rates and small sample sizes. STUDY DESIGN SIZE DURATION: This retrospective cohort study, conducted during 2013-2018, included 78 transgender women (assigned male at birth and referred for sperm cryopreservation) and 164 transgender men (assigned female at birth referred for oocyte cryopreservation). PARTICIPANTS/MATERIALS SETTING METHODS: In 2013, the previous requirement for sterilization before completion of a legal gender change was removed in Sweden. All fertile-aged transgender men and transgender women referred to a tertiary care centre for consultation concerning fertility preservation, fertility treatment or hysterectomy were identified from administrative systems. Demographic, medical and treatment data were extracted from electronic medical records and from an ART database. Logistic regression was applied to analyse factors affecting the decision to cryopreserve gametes among transgender men and transgender women. MAIN RESULTS AND THE ROLE OF CHANCE: A majority of transgender men (69.5%) and transgender women (82%), wanted to become parents. Fertility preservation was less frequent in transgender men than in transgender women (26.2% versus 75.6%, respectively). No individuals among those primarily referred for hysterectomy opted for cryopreservation of oocytes. Among transgender men, young age, no previous hormonal treatment and stating homosexual orientation were independent factors associated with the decision to cryopreserve oocytes. Among transgender women, the decision to undergo gender affirmation surgery and stating heterosexual orientation were independent factors associated with a decision to refrain from fertility preservation. Fertility treatments, using IUI or IVF with donor sperm, were mainly performed in partners of transgender men. Ten live births were reported in the group of transgender men and two for transgender women. LIMITATIONS REASONS FOR CAUTION: The main limitation is the retrospective nature of the study, with missing data for many variables. The short study period and the study population being too young to permit observation of long-term outcomes of fertility preservation and fertility treatments are reasons for caution. WIDER IMPLICATIONS OF THE FINDINGS: Our results confirm that fertility preservation has been requested by transgender people since the change in Swedish legislation in 2013. Information about aspects of fertility early in the transition process is important, since hormonal and surgical treatments may have a large impact on the decision to undergo fertility preservation. It is important to train fertility clinic staff to identify and handle the specific obstacles, as well as address the need for information and support that transgender people may have when planning for fertility preservation, fertility treatment and pregnancy. STUDY FUNDING/COMPETING INTERESTS: This research was supported by a grant from the Swedish state, under the ALF agreement between the Swedish government and the county councils (ALFGBG-720291), and by Hjalmar Svensson's Research Foundation. None of the authors has any conflict of interest to declare. TRIAL REGISTRATION NUMBER: N/A.

RESUMEN

OBJECTIVE: Fractures are related to falling. Turner syndrome (TS) is associated with hypogonadism, osteoporosis and fractures and has been considered as a syndrome of early ageing. The aim was to study whether fine motor function (FM) and body balance (BB) were impaired and related to genotype, fractures, metabolic variables and hearing. DESIGN: Cross-sectional study. PATIENTS: TS women, n = 75, mean age 30 years (range 16-59) and treated with oestrogen hormone replacement therapy (HRT) at the out-patient clinic, Sahlgrenska University Hospital, Göteborg, Sweden, and 31 healthy controls, mean age 37 years (range 24-63). MEASUREMENTS: Six FM and eight BB tests with open and closed eyes, respectively, were done. Bone mineral density was estimated with Dual energy X-ray Absorptiometry. Presence/absence of fractures was noted, blood samples were taken and audiometry was done in the TS women. RESULTS: TS women had poorer FM (27.4 +/- 6.0 vs. 32.8 +/- 2.2; P < 0.0001) and BB (28.0 +/- 8.1 vs. 34.7 +/- 2.4; P < 0.0001) than controls. FM was poorer in TS women with hearing aids compared to those without (P < 0.05). FM and BB were negatively correlated with age, waist : hip ratio and positively correlated with hearing, and bone mineral density, and BB was negatively correlated with physical activity in TS women. BB correlated negatively with age in controls. FM, BB and hearing function were poorer in 45,X, nonmosaics, than in 45,X/46,XX, mosaics. CONCLUSIONS: FM and BB were poorer in adult TS women on HRT than in controls. Higher age, hearing impairment, osteoporosis, abdominal obesity, a sedentary lifestyle and the TS per se were strong determinants, and mosaicism mitigated both fine motor function and BB in TS.

RESUMEN

BACKGROUND: The aim was to investigate if there were any differences in the degree of mosaicism between the left- and right-hand sides of the buccal mucosa in women with Turner syndrome. METHODS: Buccal smears were taken on the left- and right-hand sides at the same time for genetic analyses with fluorescence in situ hybridization in women with Turner syndrome, n = 20; 10 with and 10 without mosaicism based on the blood karyotype, and one control. A difference in the degree of mosaicism ≥5% between the sides was considered as an actual difference and <5% as equivalent. RESULTS: Of 20, 10 (50%) had ≥ 5% difference in the degree of mosaicism between the left- and right-hand sides of the buccal mucosa. The mean difference was 9.1% and the median was 4.5%, range 1%-38%. The control with ordinary female karyotype had no side difference. CONCLUSION: There was an intraorganic mosaicism of the buccal mucosa with a side difference in the degree of mosaicism of up to 38% in women with Turner syndrome. When mosaicism is strongly suspected, but not confirmed by the blood karyotype, it is recommended that buccal smears from both sides of the oral cavity should be analyzed.

RESUMEN

CONTEXT: The factors that affect the health-related quality of life (HRQoL) of women with Turner syndrome (TS) are controversial. OBJECTIVE: The aim was to describe the HRQoL of women with TS with a focus on how given GH treatment and comorbidity influence HRQoL in adulthood and to compare HRQoL of women with TS with that of women in the general population. DESIGN: Longitudinal cohort study, up to 20 years. SETTING: The Turner Center at the Section for Endocrinology and Department of Reproductive Medicine at Sahlgrenska University Hospital, Gothenburg, Sweden. PARTICIPANTS: Women with TS (n = 200), age range 16 to 78 years, were included consecutively and monitored every fifth year between 1995 and 2018. Women from the World Health Organization MONItoring of trends and determinants for CArdiovascular disease project were used as reference populations. INTERVENTIONS AND MAIN OUTCOME MEASURES: HRQoL was measured using the Psychological General Well-Being index and the Nottingham Health Profile. Associations with somatic variables were assessed using longitudinal linear regression models. RESULTS: HRQoL was not associated with GH treatment in TS in spite of a mean 5.7 cm taller height. HRQoL was only associated with height per se in one of 13 subscales (P < 0.01). HRQoL was negatively affected by higher age, higher age at diagnosis, and hearing impairment in TS. Women with TS reported a similar HRQoL to the reference population. CONCLUSIONS: No association between previous GH treatment and HRQoL was found during the up to 20 years of follow-up in women with TS. HRQoL of women with TS and the reference population was similar.

RESUMEN

OBJECTIVE: The general aim was to meet the need for empirical comparative studies of health-related quality of life (HRQoL) assessment instruments, by evaluating and comparing the psychometric properties and results of three different, widely used, generic HRQoL instruments in a population sample. The specific aims were to evaluate the subscales of the different instruments that measure the same domain and to assess the association between the HRQoL measures and a single-item self-rated health scale. DESIGN: An observational cross-sectional study. SETTING: A population-based sample from Gothenburg, Sweden, was studied in 2008 in the WHO MONItoring of trends and determinants for CArdiovascular disease. PARTICIPANTS: A total of 414 subjects were included, 77% women, age range 39-78 years. INTERVENTIONS: The Nottingham Health Profile (NHP), the Short Form-36 questionnaire (SF-36), the Psychological General Well-Being Index (PGWB) and a self-rated health scale were used. OUTCOME MEASURES: Scores were analysed for their psychometric properties, internal consistency (Cronbach's α), construct validity (Spearman's rank correlations and R2 coefficients) and discriminative ability for the presence of self-rated ill-health. RESULTS: PGWB and SF-36 had higher Cronbach's α scores than NHP. All correlations calculated between the subscales that were conceptually similar were significant (p<0.01). All subscales could differentiate the presence of self-rated ill-health according to the self-rated health scale (p<0.001). The self-rated health scale correlated strongly with all of the three HRQoL instruments used. CONCLUSIONS: There was a high concordance between the instruments within each domain that was conceptually similar. All three HRQoL instruments (PGWB, SF-36 and NHP) could discriminate the presence of self-rated ill-health. The simple and quick self-rated health scale correlated strongly with the more time-consuming PGWB, SF-36 and NHP. The result supports the existence of a strong association between the self-rated health scale and HRQoL in the general population.

RESUMEN

OBJECTIVES: To study the prevalence and incidence of elevated liver enzymes and their relationship with body weight, metabolic factors and other diseases in Turner syndrome (TS). DESIGN: Five-year follow-up. PATIENTS: Women with TS (n = 218, mean age 33 +/- 13, range 16-71 years) from outpatient clinics at university hospitals in Sweden. MEASUREMENTS: Fasting blood samples for aspartate (AST) and alanine aminotransferase (ALT), bilirubin, alkaline phosphatase (ALP), gamma-glutamyl transferase (GT), viral hepatitis serology and hepatic auto-antibodies, vitamin B12, blood glucose, lipids and hormones. RESULTS: Seventy-nine subjects (36%) had one or more liver enzyme levels higher than the reference level, the most prevalent being GT. Karyotype 45,X was present in 51% of all TS women and in 48% of those with elevated liver enzymes. Body weight, body mass index (BMI), total cholesterol, triglycerides, and apolipoproteins A and B at start were higher in TS women with elevated liver enzymes than in TS women with normal levels. At 5 years, AST, ALT and GT were increased and another 23% of patients had developed elevated liver enzymes, that is, 59% in total (36% + 23%), while in 6%, the elevated liver enzymes had been normalized and all 6% also had lowered cholesterol levels. Multivariate analysis showed that GT was correlated with total cholesterol; P = 0.0032 at start and P = 0.0005 at 5 years, independently of other factors. Liver biopsy in six TS women showed one cholangitis, one hepatitis C, two steatosis and two normal biopsies. Withdrawal of oestrogen substitution did not influence the liver enzymes. CONCLUSIONS: Pathological liver enzymes were common in TS women, with a prevalence of 36% at 33 years of age, an annual incidence over 5 years of 3.4%. There was no relation to karyotype, alcohol, viral hepatitis, E(2) or autoimmunity, but a connection with total serum cholesterol.

RESUMEN

Turner syndrome (TS) is caused by a sex chromosome aberration. The aim was to study the prevalence and incidence of thyroid disease in adults with TS. Women with TS (n = 91; mean age, 37.7 +/- 11 yr) were compared with an age-matched female random population sample (n = 228). At baseline, 15 (16%) TS women were treated for hypothyroidism, and elevated serum TSH was found in another eight (9%). As a result, hypothyroidism was more common in women with TS (25%) than in controls (2%; P < 0.0001). Serum free T4 was lower (P = 0.02), and serum TSH was higher (P < 0.0001) in TS women than in age-matched controls. Of all TS women with hypothyroidism, 10 (43%) had an elevated thyroid peroxidase antibody titer vs. 15 (22%) of those without hypothyroidism (P < 0.05), evenly distributed between the karyotype 45,X and mosaicism. A high body mass index, but not a family history or blood lipids, was associated with hypothyroidism in TS. After the 5-yr follow-up, an additional 11 (16%) developed hypothyroidism, of whom four (36%) had elevated thyroid peroxidase. Altogether, 34 (37%) TS women had hypothyroidism after the 5-yr follow-up. Autoimmune hypothyroidism was common, with an annual incidence of 3.2% in TS. Thyroid function should be checked regularly in TS.

RESUMEN

In the normal population, loss of one of the sex chromosomes leading to monosomy (45,X) is a part of the aging process. In Turner syndrome (TS), the classic karyotype 45,X is found in up to 50% at birth, and others have a second cell line; mosaicism. The aim was to study if the chromosomal pattern in TS women changes over time. Fluorescence in situ hybridization was performed on buccal smear cells obtained twice, 10 years apart, from 42 women with TS aged 26-66 years (mean±standard deviation: 42.0±11.6). DNA probes specific for chromosomes X (DXZ1) and Y (DYZ3) were used and >100 cells were analyzed/patient. Nineteen women had monosomy (45,X) (<10% 46,XX), nine had 45,X/46,XX mosaicism, and 14 had iso, ring, or a marker chromosome at baseline. At 10 years, the percentage of diploid cells had increased in 29 of 42 women (69%), with an average increase of 5.7±13.0%. There was a positive correlation between age and % change in diploid 46,XX or 46,XY cells (r=0.38, p=0.023). This new finding might have relevance for the life expectancy in TS.

RESUMEN

Pregnancies occurred in 57 (12%) of 482 Swedish women with Turner syndrome with a liveborn rate of 54% in 124 pregnancies. Spontaneous pregnancies occurred in 40%, mainly in women with 45,X/46,XX mosaicism, and oocyte donation in 53% where miscarriages were less frequent, odds ratio = 0.43 (95% confidence interval 0.17-1.04).

RESUMEN

CONTEXT: GH and/or oxandrolone are used to promote growth in Turner syndrome (TS). OBJECTIVE: The aim of this study was to compare quality of life (QoL) in TS women with controls and determine the impact of growth promoting therapy on QoL in TS women. DESIGN: This was a cross-sectional, case-control study. SETTING: The study was conducted at an outpatient clinic at Sahlgrenska University Hospital, Göteborg, Sweden. PATIENTS: PATIENTS included 111 TS women (age range 18-59 yr) and 111 randomly selected, age-matched women (25-54 yr) from the World Health Organization Monitoring Trends and Determinants for Cardiovascular Disease project (Göteborg, Sweden) served as controls. MAIN OUTCOME MEASURES: QoL was estimated by the Psychological General Well-Being scale (anxiety, depressed mood, positive well-being, self-control, general health and vitality) and the Nottingham Health Profile (physical mobility, pain, sleep, energy, social isolation, and emotional reactions). RESULTS: TS women reported more social isolation than controls (P < 0.001). After age adjustment, significantly less pain (<0.05) was reported attributable to GH treatment within TS. No significant difference in any other subscales used could be shown. In TS, QoL was negatively affected by higher current age and age at diagnosis and positively affected by better body balance, fine motor function, and higher bone mineral density. CONCLUSIONS: Social isolation was more commonly reported in the whole TS cohort than in the population. Except for less pain, no significant impact on QoL attributable to GH treatment could be found, despite the mean +5.1 cm final height.

RESUMEN

The aim of this study was to describe marital status, sexual history, and sexual functioning in a group of women with Turner syndrome, and to compare the results with general Swedish population data. The sample consists of 57 women over 18 years of age. Data were collected from an interview, and using two self-report questionnaires: the McCoy Sexual Rating Scale and the Relationship Rating Scale (RS). Compared to population data, the women with Turner syndrome were less likely to have a partner and had had their sexual debut later. Single women differed more from the general population than did women with a partner, regarding sexual desire and sexual activity. Several women with a partner reported sexual problems, but unanimously reported being satisfied with their sex life and partner relationship. The level of sexual desire in women with Turner syndrome is discussed in relation to Levine's model of human sexual desire, where psychological and social motivational factors are considered in addition to a biologically based sexual drive (Levine, 1992).

RESUMEN

OBJECTIVE: To study genotype-phenotype correlations in Turner syndrome (TS) regarding body composition, cardiovascular risk factors, stigmata and age at diagnosis vs. degree of mosaicism estimated as the percentage of 45,X and 46,XX cells. METHODS: One hundred and twenty-six TS women, mean age 31 years, were examined by three specialists, who reported stigmata independent of each other. Dual energy X-ray absorptiometry (DXA) was used to measure bone mineral density (BMD). The karyotype was blinded. Fluorescence in situ hybridization (FISH) was performed on buccal cells. A random population sample served as controls. RESULTS: Forty-four per cent exhibited a 45,X karyotype and 56% a second-cell line, while 27% of all had a 45,X/46,XX mosaicism. Five 45,X cases with a conventional karyotype were 45,X/46,XX mosaic according to FISH. At diagnosis, 45,X cases were younger (P < 0.05) and had more stigmata per person (P < 0.01) than the mosaics. TS with marker chromosome X or Y, iso or ring, did not differ from 45,X in this aspect. The mosaics had higher BMD and SHBG and lower total cholesterol and FSH than TS with 45,X and did not differ compared with controls in terms of body mass index (BMI), waist/hip ratio, BMD, blood pressure, cholesterol, triglycerides, SHBG, diabetes or osteoporosis. The number of stigmata correlated positively to BMI, waist/hip ratio, cholesterol and %45,X and inversely to height and %46,XX according to FISH. CONCLUSIONS: Mosaicism seems to mitigate the TS phenotype and the cardiovascular risk factor profile. Mosaics were diagnosed 8 years later than 45,X cases. This emphasizes the necessity for a stricter genotype categorization not only in the clinic but also in research on TS than previously adopted.

RESUMEN

PURPOSE: To present a case involving pregnancies in a Turner woman with Y-chromosome mosaicism. METHOD: A descriptive case report of a single patient. RESULTS: A 39-year-old woman was admitted to the endocrine clinic due to fatigue and premature menopause. She had tried in-vitro fertilization and oocyte donation twice without pregnancies but became spontaneously pregnant at age 36 and 37 and delivered two girls. During the seventh month of the second pregnancy, a dissecting aortic aneurysm, a coarctation, and subsequently a pheochromocytoma were detected and repaired. Hypothyroidism developed. Turner syndrome was diagnosed. Fluorescence in situ hybridization (FISH) analysis of lymphocytes revealed 31% XY cells and 4% XYY cells, while 66% of buccal cells had an XY constitution. Oophorectomy revealed no malignancy. FISH revealed 54% XY cells in the left gonad and 38% XY cells in the right. CONCLUSION: Turner syndrome should be suspected in women with aortic dissection, in general, but especially in those with additional features such as horseshoe kidney, coarctation, and infertility.
