Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- Livskvalitet var inte relaterad till längd, karyotyp eller hormonbehandling men påverkades negativt av social isolering, osteoporos och dålig balans vid Turners syndrom. Det är viktigt med en aktiv livsstil redan från barnsben för att få enbra muskel- och balansfunktion och därigenom en god livskvalitet.

- 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.

- Hearing loss, auricular anomalies and middle ear infections are common findings in many genetic disorders, but the mechanisms have remained unknown. We studied ear and hearing problems in Turner's syndrome (TS) in relation to the degree of X chromosome loss (i.e. degree of mosaicism) and growth. One hundred and nineteen girls and women with TS were studied regarding audiometry, fluorescent in situ hybridisation, serum concentration of insulin-like growth factor-1 (IGF-1) and body height. It was found that sensorineural hearing loss and occurrence of auricular anomalies were significantly increased the greater the proportion of 45,X cells in a particular individual (P<0.05 and P<0.001, respectively). Middle ear infections and sensorineural hearing loss were negatively correlated with IGF-1 (P<0.05 and P<0.001, respectively). Hearing correlated positively with height (P<0.01) and IGF-1 independently of age (P<0.05). Height correlated positively with IGF-1 (P<0.001). Auricular malformations, middle ear infections and hearing impairment in TS were interpreted as due to growth disturbances during development. A new hypothesis on the pathophysiology of external, middle and inner ear disorders due to a delayed cell cycle caused by chromosomal aberrations per se and not only to the specific X chromosome deletion is presented.

- Hearing and balance deteriorate, and fracture incidence increases with age, especially in women. The aim of the present study was to investigate whether impaired hearing and body balance are stronger predictors of fractures than bone mass. Between 1995 and 1997, 80 women, aged 50 to 70 years, with primary osteoporosis, taking menopausal hormone therapy, mainly for menopausal symptoms, participated in a double-blind, randomized, placebo-controlled study of treatment with growth hormone versus placebo. All women received calcium 750 mg and vitamin D 400 U daily. They were then examined yearly until 2007 and followed up by registers until 2020. Hearing was assessed by audiometry. Body balance and fine motor function were tested according to the Bruininks-Oseretsky test. Bone properties were measured with DXA. Data on fractures were derived from the Gothenburg Hospital register. Over the 25-year follow-up, 50 women (63%) sustained 104 fractures, most often related to accidental falls. Thoracic and lumbar spine fractures were most common (36%). Other fractures occurred in the pelvis (14%), humerus (14%), hip (11%), and wrist (10%). Hearing impairment at baseline, measured as pure tone average-high (p = 0.007), pure tone average-mid (p = 0.003), and speech-recognition score (p = 0.025), was associated with a subsequent first fracture, as were worse body balance (p = 0.004), upper limb coordination (p = 0.044), and higher running-speed agility (p = 0.012). After adjustment for age and BMD, pure tone average-high (p = 0.036), pure tone average-mid (p = 0.028), and body balance (p = 0.039) were still significantly associated with incident fractures. Bone mineral content, BMD, and treatment at baseline were not associated with subsequent fracture. In conclusion, hearing and body balance at baseline exceeded initial BMD in predicting incident fractures in osteoporotic women regardless of treatment during 25-year follow-up. (c) 2021 The Authors.

- High-frequency hearing loss and S-Ca, but not hormones related to bone structure and strength, or lifestyle factors, predicted incident fractures during 17 years of follow-up in women up to 97 years of age. Introduction The fracture risk increases and inner ear function deteriorates with increasing age. The aim of this study was to investigate whether hearing loss was of greater importance than bone-regulating hormones for the risk of fracture in elderly women. Methods In 1997, a random population sample of 63-82-year-old women, n = 552, underwent a physical examination, audiometry and blood sampling for analyses of serum albumin-adjusted calcium (S-Ca), parathyroid hormone (PTH), 25(OH) vitamin D and insulin-like growth factor-1 (IGF-1). Data on medication, lifestyle, previous fractures, hearing, vision and dizziness were obtained using questionnaires. Data on subsequent fractures were retrieved, and censored at death, through December 2013. Results In 1997, 228 women (41%) reported a previous fracture, most commonly of the wrist (18%). During the following 17 years, 323 fractures occurred in 207 women (38%). Hip fractures were the most frequent, in 96 women (17%). In a Cox regression analysis adjusted for age and previous fractures, hearing loss, reflected by a high pure tone average >= 59 dB, almost doubled the risk of a subsequent fracture (hazard ratio (HR) 1.81, 95% CI 1.25; 2.61, p = 0.002). S-Ca (HR 1.21 (1.02; 1.44) p = 0.028) also predicted future fractures, whereas PTH, IGF-1, 25(OH) vitamin D, hormone replacement therapy, smoking, degree of physical activity, impaired vision and dizziness did not. Conclusion Hearing loss and higher S-Ca, but not bone-regulating hormones, medication or lifestyle factors predicted incident fractures, mainly caused by falling, during 17 years of follow-up in women up to 97 years of age.

- 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.

- 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.

- 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. STUDY FUNDING/COMPETING INTEREST(S): No conflicts of interest exist. The study has been supported by grants from the Gothenburg Medical Society, the Medical Care executive Board of the Region Västra Götaland, grants from the ALF agreement at the Sahlgrenska University Hospital, the Hjalmar Svensson foundation, the Swedish Board of Health and Welfare, the Swedish Heart Lung Foundation and the Swedish Council for Working Life and Social Research. TRIAL REGISTRATION NUMBER: None.

- Context: Women with Turner syndrome (TS) have high risk of cardiovascular complications and hypertensive disorders. Few studies have analyzed obstetric outcome in women with TS. Objective: This study compared obstetric outcome in women with TS karyotype with women in the general population. Design: The Swedish Genetic Turner Register was cross-linked with the Swedish Medical Birth Register between 1973 and 2007. Obstetric outcome in singletons was compared with a reference group of 56,000 women from the general population. Obstetric outcome in twins was described separately. Results: A total of 202 singletons and three sets of twins were born to 115 women with a TS karyotype that was unknown in 52% at time of pregnancy. At first delivery, TS women of singletons were older than controls (median 30 vs. 26 yr, P < 0.0001). Preeclampsia occurred in 6.3 vs. 3.0% (P = 0.07). Aortic dissection occurred in one woman. Compared with the general population, the gestational age was shorter in children born by TS women (-6.4 d, P = 0.0067), and median birth weight was lower (-208 g, P = 0.0012), but sd scores for weight and length at birth were similar. The cesarean section rate was 35.6% in TS women and 11.8% in controls (P < 0.0001). There was no difference in birth defects in children of TS women as compared with controls. Conclusions: Obstetric outcomes in women with a TS karyotype were mostly favorable. Singletons of TS women had shorter gestational age, but similar size at birth, adjusted for gestational age and sex. Birth defects did not differ between TS and controls.
