Development of Health-Related Quality of Life Instruments for Young Children With Disorders of Sex Development (DSD) and Their Parents.
Ontology highlight
ABSTRACT: Objective
Research in disorders of sex development (DSD) is hindered by a lack of standardized measures sensitive to the experiences of affected children and families. We developed and evaluated parent proxy (children 2-6 years) and parent self-report (children ≤6 years) health-related quality of life (HRQoL) instruments for DSD.Methods
Items were derived from focus groups and open-ended interviews. Clarity and comprehensiveness were assessed with cognitive interviews. Psychometric properties were examined in a field survey of 94 families.Results
Measures demonstrated adequate to good psychometrics, including internal consistency, test-retest reliability, convergent validity, and ability to detect known-group differences. Parents reported greatest stress on Early Experiences , Surgery , and Future Concerns scales.Conclusions
These instruments identify patients' and families' needs, monitor health and quality of life status, and can evaluate clinical interventions. Findings highlight the need for improved psychosocial support during the diagnostic period, better parent-provider communication, and shared decision-making. HRQoL measures are needed for older youth.

Project description:dsd-LIFE is a comprehensive cross-sectional clinical outcome study of individuals with disorders/differences of sex development (DSD). This study focuses on various rare genetic conditions characterized by impaired gonadal or adrenal functionality.The study aims to assess quality of life (QoL) as a measure of psychosocial adaptation, psychosexual and mental health aspects as major outcomes. Health status and functioning, medical and surgical therapies, participants' views on health care, psychological and social support, sociodemographic factors and their interrelations will be investigated as factors associated with the outcomes. In addition, ethical considerations in the field of DSD are addressed and previous experiences with health care were gathered. One thousand and forty participants with different DSD conditions were recruited by 14 study centres in 6 European countries (France, Germany, the Netherlands, Poland, Sweden and the United Kingdom) from February 2014 until September 2015. The conditions included were: Turner syndrome (n = 301); 45,X0/46,XY conditions (n = 45); Klinefelter syndrome (n = 218); 47,XYY (n = 1); 46,XY gonadal dysgenesis/ovotestes (n = 63); complete androgen insensitivity (CAIS) (n = 71); partial androgen insensitivity (PAIS) (n = 35) and androgen synthesis disorders (n = 20); severe hypospadias (n = 25); other or non-classified 46,XY DSD (n = 8); 46,XX congenital adrenal hyperplasia (CAH) (n = 226); 46,XX gonadal dysgenesis/ovotestis (n = 21); and 46,XX in males (n = 6). For an add-on study, 121 46,XY male-assigned individuals with CAH due to 21-hydroxylase deficiency were recruited. Mean age of participants' was 32.4 (+/- 13.6 years).Participation was high in conditions not commonly described as DSD, such as Turner and Klinefelter syndromes or CAH. Recruitment of individuals with XY DSD conditions proved to be more difficult. The data collection of PROs resulted in high data quality. Within medical and physical examination data, more missings and/or inaccurate data were found than expected. The European dsd-LIFE study recruited and evaluated the largest cross-sectional sample of individuals with different conditions classified under the term DSD. The data from this large sample will provide a sufficient basis for evidence-based recommendations for improvement of clinical care of individuals affected by a DSD condition.German Clinical Trials Register DRKS00006072 .

Project description:Although many next-generation sequencing platforms are being created around the world, implementation is facing multiple hurdles. A strong hurdle to the full adherence of clinical teams to the Disorders of Sex Development Translational Research Network (DSD-TRN) guidelines for standardization of reporting and practice is the current lack of integration of the standardized clinical forms into the various electronic medical records at different sites. Time allocated to research is also limited. In spite of these hurdles, genetic information for half the enrolled patients is already available in the DSD-TRN registry, and early results demonstrate the value of such an infrastructure.

Project description:BackgroundThere is a paucity of tools that can be used in routine clinical practice to assess the psychosocial impact of Disorders/Differences of Sex Development (DSD) on parents and children.ObjectiveTo evaluate the use of short Parent Self-Report and Parent Proxy-Report questionnaires that can be used in the outpatient setting.MethodsPreviously validated DSD-specific and generic items were combined to develop a Parent Self-Report questionnaire and a Parent Proxy-Report questionnaire for children under 7?years. Of 111 children approached at one tertiary paediatric hospital, the parents of 95 children (86%) with DSD or other Endocrine conditions completed these questionnaires.ResultsQuestionnaires took under 10?min to complete and were found to be easy to understand. Compared to reference, fathers of children with DSD reported less stress associated with Clinic Visits (p?=?0.02) and managing their child's Medication (p?=?0.04). However, parents of children with either DSD or other Endocrine conditions reported more symptoms of Depression (p?=?0.03). Mothers of children with DSD reported greater Future Concerns in relation to their child's condition (median SDS -?0.28; range?-?2.14, 1.73) than mothers of children with other Endocrine conditions (SDS 1.17; -?2.00, 1.73) (p?=?0.02). Similarly, fathers of children with DSD expressed greater Future Concerns (median SDS -1.60; -?4.21, 1.00) than fathers of children with other Endocrine conditions (SDS 0.48; -?2.13, 1.52) (p?=?0.04).ConclusionDSD was associated with greater parental concerns over the child's future than other Endocrine conditions. Brief parent-report tools in DSD can be routinely used in the outpatient setting to assess and monitor parent and patient needs.

Project description:OBJECTIVE:The knowledge about health status in adults with disorder of sex development (DSD) is scarce. DESIGN AND METHODS:A cross-sectional observational study in 14 European tertiary centers recruited 1040 participants (717 females, 311 males, 12 others) with DSD. Mean age was 32.4?±?13.6 year (range 16-75). The cohort was divided into: Turner (n?=?301), Klinefelter (n?=?224), XY-DSD (n?=?222), XX-DSD (excluding congenital adrenal hyperplasia (CAH) and 46,XX males) (n?=?21), 46,XX-CAH (n?=?226) and 45,X/46,XY (n?=?45). Perceived and objective health statuses were measured and compared to European control data. RESULTS:In DSD, fair to very good general health was reported by 91.4% and only 8.6% reported (very) bad general health (controls 94.0% and 6.0%, P?<?0.0001). Longstanding health issues other than DSD and feeling limited in daily life were reported in 51.0% and 38.6%, respectively (controls 24.5% and 13.8%, P?<?0.0001 both). Any disorder except DSD was present in 84.3% (controls 24.6%, P?<?0.0001). Males reported worse health than females. In the subgroup analysis, Klinefelter and 46,XX-DSD patients reported bad general health in 15.7% and 16.7%, respectively (Turner 3.2% and CAH 7.4%). Comorbidities were prevalent in all DSD subgroups but Klinefelter and Turner were most affected. Early diagnosis of DSD and a healthy lifestyle were associated with less comorbidities. CONCLUSIONS:Overall, general health appeared to be good but a number of medical problems were reported, especially in Klinefelter and Turner. Early diagnosis of DSD and a healthy lifestyle seemed to be important. Lifelong follow-up at specialized centers is necessary.

Project description:BackgroundThis cross-sectional study assessed both family and individual quality of life (QOL), and their association with self-esteem, optimism, chronic psychological stress, anxiety, and depression in parents of children with chronic conditions.MethodsParents of children with Down syndrome (DS), autistic spectrum disorder (ASD), cerebral palsy (CP), diabetes mellitus type 1 (DMT1), and parents of children without chronic diseases with typical development (TD) were included. Multivariate linear regression analysis was used to assess parental characteristics associated with the domains of individual and family QOL.ResultsCompared to the parents of TD children, parents of children with ASD and DS were more likely to report reduced family QOL in all domains, while parents of children with DMT1 had lower parental perception. Self-esteem was positively associated with all domains of individual QOL, while optimism was associated with the overall individual QOL perception and health. Higher stress perception was negatively associated with most of the domains of individual and family QOL.ConclusionsThis study confirmed that parents of children with chronic conditions are more likely to have lower perception of both individual and family QOL, which were associated with self-esteem, chronic stress, anxiety, and depression. Interventions should focus not only on the child with a chronic condition but on parents too.

Project description:OBJECTIVES:Severe to profound hearing loss is associated with worse health-related quality of life (HRQoL), reflecting the wide-ranging effects of deafness on spoken language, cognition, and social/behavioral development. However, there are currently no cochlear implant (CI)-specific HRQoL measures that were developed using the Food and Drug Administration Guidance on patient-reported outcomes. This study developed the first HRQoL instruments (CI-QoL) for children with CIs, ages 6 to 12, and a parent-proxy measure for this age group. DESIGN:Two phases of instrument development were conducted. Phase 1 consisted of a literature review yielding a conceptual framework and discussion guides to elicit information from stakeholder focus groups at CI clinics in Miami and Philadelphia (n = 30; e.g., physicians, speech pathologists). During phase 2, open-ended interviews were conducted with 21 parent-child dyads (M child age = 9.1 years) recruited from these two clinics. Interviews were transcribed, followed by content analysis in NVivo to identify the most frequent and difficult themes. Items were then derived from these themes to form the initial draft instruments. A multimodal approach was used to create the child-report version (i.e., pictorial representations, audio recording of items, written text above the drawings) to maximize comprehension and ease of responding. Both measures were developed to be administered electronically on a tablet device. In phase 3, a new set of parent-child dyads (n = 20; child age M = 9.2 years) completed a cognitive testing protocol to ensure clarity, ease of use, and comprehensiveness. Cognitive testing led to revisions and finalization of the instruments. RESULTS:The final self-report measure contained 33 items across eight domains: Noisy Environments, Academic Functioning, Child Acceptance, Oral Communication, Social Functioning, Fatigue, Emotional Functioning, and Device Management. The final parent-proxy measure included 42 items on nine scales: the same eight scales that appear on the child version, with the addition of Behavior Problems. Correlations between child and parent reports on each scale ranged from r = 0.08 to 0.48. CONCLUSIONS:CI-specific HRQoL instruments have now been developed for school-age children with CIs, with an accompanying parent-proxy version. After a psychometric validation, these CI-specific measures will enable us to track long-term outcomes, evaluate the efficacy of interventions to improve CI use (e.g., single versus bilateral implantation, AV therapy, maternal sensitivity training), and provide a profile of the "whole child's" functioning to facilitate care.

Project description:BACKGROUND: The German Network of Disorders of Sex Development (DSD)/Intersexuality carried out a large scale clinical evaluation study on quality of life, gender identity, treatment satisfaction, coping, and problems associated with diagnoses and therapies in individuals with disorders of sex development (DSD). DSD are a heterogeneous group of various genetic disorders of sex determination or sex differentiation, all of which are rare conditions. In about half of all cases the molecular genetic diagnosis is unknown and diagnosis rests on clinical features. METHODS AND DESIGN: The multi-centre clinical evaluation study includes short-term follow-up in some and cross-sectional assessments in all age and diagnostic groups fitting the criteria of DSD. Recruitment was from January 2005 until December 2007 in whole Germany and, additionally, in 2007 in Austria and German-speaking Switzerland. The study consists of a psychosocial inquiry for children, adolescents and their parents, and adults with standardized instruments and the collection of DSD-specific medical data by the attending physician. The main goal was the description of clinical outcomes and the health-care situation of individuals with DSD using a broad generic definition of DSD including all conditions with a mismatch of chromosomal, gonadal and phenotypical sex. 439 children and adolescents, their parents and adults with DSD participated. DISCUSSION: The clinical evaluation study represents the most comprehensive study in this clinical field. The paper discusses the study protocol, the data management and data quality as well as the classification used, and it describes the study population. Given the lack of large datasets in rare conditions such as DSD and often biased results from small scale clinical case series, the study aims to generate concrete hypotheses for evidence-based guidelines, which should be tested in further studies.

Project description:BACKGROUND: Parents of children with chronic conditions are known to be at risk of impairment in their quality of life (QoL). Studies considering other chronic conditions proposed diverse factors to have an impact on the parent's QoL. So far, there has been little research on parents who have a child with phenylketonuria (PKU). This study was designed to evaluate the parental quality of life (PQoL) of parents of children and adolescents who have PKU and identify possible predictors of PQoL. METHODS: In this cross-sectional study 89 parents completed self-report measures of PQoL, family stress, social support, and parental coping. To determine the impact of these potential predictors on PQoL, regression and mediation analyses were performed. RESULTS: Most parents coped well with their children's metabolic disorder. Family stress (??=?-0.42; p?<?0.001) and perceived social support (??=?0.33; p?=?0.001) were proven to be the most powerful predictors, accounting together for 45% of the variance of PQoL. Social support mediated the association between family stress and PQoL. CONCLUSIONS: The current study indicates that parents of younger children are an especially vulnerable group. Members of health-care teams should be able to identify and empower vulnerable parents to seek and maintain social support.

Project description:In contrast to disorders of sexual differentiation caused by lack of androgen production or inhibited androgen action, defects affecting development of the bipotent genital anlagen have rarely been investigated in humans. We have previously documented that the transcription factor FOXF2 is highly expressed in human foreskin. Moreover, Foxf2 knockout mice present with cleft palate in combination with hypoplasia of the genital tubercle. We hypothesized that humans with disorders of sex development (DSD) in combination with cleft palate could have mutations in the FOXF2 gene. Eighteen children with DSD and cleft palate were identified in the Lübeck DSD database (about 1,500 entries). Genomic DNA sequence analysis of the FOXF2 gene was performed and compared with 10 normal female and 10 normal male controls, respectively. Two heterozygous DNA sequence variations were solely present in one single patient each but in none of the 20 normal controls: a duplication of GCC (c.97GCC[9]+[10]) resulting in an extra alanine within exon 1 and a 25*G>A substitution in the 3'-untranslated region. Two patients carried a c.262G>A sequence variation predicting for an Ala88Thr exchange which was also detected in 2 normal controls. Two silent mutations, c.1272C>T (Ser424Ser) and c.1284T>C (Tyr428Tyr), respectively, occurred in the coding region of exon 2, again in both patients and normal controls. In conclusion, the majority of the detected sequence alterations were polymorphisms without obvious functional relevance. However, it cannot be excluded that the 2 unique DNA sequence alterations could have affected FOXF2 on the mRNA or protein level thus contributing to the observed disturbances in genital and palate development.

Project description:Both otoacoustic emissions (OAEs) and auditory evoked potentials (AEPs) are sexually dimorphic, and both are believed to be influenced by prenatal androgen exposure. OAEs and AEPs were collected from people affected by 1 of 3 categories of disorders of sex development (DSD) - (1) women with complete androgen insensitivity syndrome (CAIS); (2) women with congenital adrenal hyperplasia (CAH); and (3) individuals with 46,XY DSD including prenatal androgen exposure who developed a male gender despite initial rearing as females (men with DSD). Gender identity (GI) and role (GR) were measured both retrospectively and at the time of study participation, using standardized questionnaires. The main objective of this study was to determine if patterns of OAEs and AEPs correlate with gender in people affected by DSD and in controls. A second objective was to assess if OAE and AEP patterns differed according to degrees of prenatal androgen exposure across groups. Control males, men with DSD, and women with CAH produced fewer spontaneous OAEs (SOAEs) - the male-typical pattern - than control females and women with CAIS. Additionally, the number of SOAEs produced correlated with gender development across all groups tested. Although some sex differences in AEPs were observed between control males and females, AEP measures did not correlate with gender development, nor did they vary according to degrees of prenatal androgen exposure, among people with DSD. Thus, OAEs, but not AEPs, may prove useful as bioassays for assessing early brain exposure to androgens and predicting gender development in people with DSD.
