    • Esophageal atresia with or without tracheoesophageal fistula (EA/TEF) is the most common congenital malformation of the upper digestive tract. This study represents the first genome-wide association study (GWAS) to identify risk loci for EA/TEF. We used a European case-control sample comprising 764 EA/TEF patients and 5,778 controls and observed genome-wide significant associations at three loci. On chromosome 10q21 within the gene CTNNA3 (p = 2.11 × 10−8; odds ratio [OR] = 3.94; 95% confidence interval [CI], 3.10–5.00), on chromosome 16q24 next to the FOX gene cluster (p = 2.25 × 10−10; OR = 1.47; 95% CI, 1.38–1.55) and on chromosome 17q12 next to the gene HNF1B (p = 3.35 × 10−16; OR = 1.75; 95% CI, 1.64–1.87). We next carried out an esophageal/tracheal transcriptome profiling in rat embryos at four selected embryonic time points. Based on these data and on already published data, the implicated genes at all three GWAS loci are promising candidates for EA/TEF development. We also analyzed the genetic EA/TEF architecture beyond the single marker level, which revealed an estimated single-nucleotide polymorphism (SNP)-based heritability of around 37% ± 14% standard deviation. In addition, we examined the polygenicity of EA/TEF and found that EA/TEF is less polygenic than other complex genetic diseases. In conclusion, the results of our study contribute to a better understanding on the underlying genetic architecture of ET/TEF with the identification of three risk loci and candidate genes. © 2022 The Authors

  • A genome-wide association study with tissue transcriptomics identifies genetic drivers for classic bladder exstrophy
  • 2022
  • Ingår i: Communications biology. - : Springer Science and Business Media LLC. - 2399-3642. ; 5:1, s. 1203-
  • Tidskriftsartikel (refereegranskat)abstract
    • Classic bladder exstrophy represents the most severe end of all human congenital anomalies of the kidney and urinary tract and is associated with bladder cancer susceptibility. Previous genetic studies identified one locus to be involved in classic bladder exstrophy, but were limited to a restrict number of cohort. Here we show the largest classic bladder exstrophy genome-wide association analysis to date where we identify eight genome-wide significant loci, seven of which are novel. In these regions reside ten coding and four non-coding genes. Among the coding genes is EFNA1, strongly expressed in mouse embryonic genital tubercle, urethra, and primitive bladder. Re-sequence of EFNA1 in the investigated classic bladder exstrophy cohort of our study displays an enrichment of rare protein altering variants. We show that all coding genes are expressed and/or significantly regulated in both mouse and human embryonic developmental bladder stages. Furthermore, nine of the coding genes residing in the regions of genome-wide significance are differentially expressed in bladder cancers. Our data suggest genetic drivers for classic bladder exstrophy, as well as a possible role for these drivers to relevant bladder cancer susceptibility.

  • Establishment of a condition-specific quality-of-life questionnaire for children born with esophageal atresia aged 2-7 across 14 countries
  • 2023

    • BackgroundEsophageal atresia (EA) is a rare congenital anomaly characterized by a discontinuity of the esophagus. Following surgical repair, survival rates have improved dramatically the past decenniums and today exceed 90%, but the children commonly present with esophageal and respiratory morbidity. In 2018, a condition-specific quality-of-life questionnaire for children with esophageal atresia (EA) aged 2-7 in Sweden-Germany was finalized (The EA-QOL questionnaire). The study aim was to describe the evaluation of the new translations across 12 new countries in Europe, Asia, Africa, Central-and North America.MethodsFollowing forward-backward translation into the new languages, the 17-item EA-QOL questionnaire was tested in cognitive debriefing interviews with parents of children with EA aged 2-7. Parents rated if each item was easy to understand (clarity) and sensitive to answer (interference with personal integrity). They could skip responding to a non-applicable/problematic item and give open comments. Predefined psychometric criteria were used; item clarity >= 80%/item sensitive to answer <= 20%/item feasibility <= 5% missing item responses. The decision to modify the translation was based on native expert, patient stakeholder, and instrument developer review, and the need for harmonization between translations.ResultsSimilar to findings in the Swedish-German cognitive debriefing, the cross-cultural analysis of input from 116 parents from 12 new countries (4-14 parents, median 9 parents/country) showed that all items in the EA-QOL questionnaire fulfilled the criteria for item clarity >= 80% and sensitive to answer (ranging from 1%-4.5%), although results varied between countries. Four items had missing responses between 5.2% and 13.4%, three within the same domain and were in line with parents' explanations. Poor translations and feasibility were improved.ConclusionsBased on parent input, the collaboration between native experts, patient stakeholders, and instrument developers, a linguistic version of the EA-QOL questionnaire for children aged 2-7 for use in and across 14 countries has been established. These efforts have set the conditions for a cross-cultural field test of the EA-QOL questionnaire and will open the doors for a new chapter in outcome research, registries, and clinical practice concerning children with EA. In the long-term, this will help increase knowledge of the disease's burden, promote patient-centeredness, exchange of information between nations, and strengthen evidence-based treatments for children born with EA.

    • Background Measuring health-related quality of life (QoL) after surgery is essential for decision making by patients, surgeons, and payers. The aim of this consensus conference was twofold. First, it was to determine for which diseases endoscopic surgery results in better postoperative QoL than open surgery. Second, it was to recommend QoL instruments for clinical research. Methods An expert panel selected 12 conditions in which QoL and endoscopic surgery are important. For each condition, studies comparing endoscopic and open surgery in terms of QoL were identified. The expert panel reached consensus on the relative benefits of endoscopic surgery and recommended generic and disease-specific QoL instruments for use in clinical research. Results Randomized trials indicate that QoL improves earlier after endoscopic than open surgery for gastroesophageal reflux disease (GERD), cholecystolithiasis, colorectal cancer, inguinal hernia, obesity (gastric bypass), and uterine disorders that require hysterectomy. For spleen, prostate, malignant kidney, benign colorectal, and benign non-GERD esophageal diseases, evidence from nonrandomized trials supports the use of laparoscopic surgery. However, many studies failed to collect long-term results, used nonvalidated questionnaires, or measured QoL components only incompletely. The following QoL instruments can be recommended: for benign esophageal and gallbladder disease, the GIQLI or the QOLRAD together with SF-36 or the PGWB; for obesity surgery, the IWQOL-Lite with the SF-36; for colorectal cancer, the FACT-C or the EORTC QLQ-C30/CR38; for inguinal and renal surgery, the VAS for pain with the SF-36 (or the EORTC QLQ-C30 in case of malignancy); and after hysterectomy, the SF-36 together with an evaluation of urinary and sexual function. Conclusions Laparoscopic surgery provides better postoperative QoL in many clinical situations. Researchers would improve the quality of future studies by using validated QoL instruments such as those recommended here.

  • Clinical Factors Affecting Condition-Specific Quality-of-Life Domains in Pediatric Patients after Repair of Esophageal Atresia: The Swedish-German EA-QOL Study
  • 2020
  • Ingår i: European Journal of Pediatric Surgery. - : Georg Thieme Verlag KG. - 0939-7248 .- 1439-359X. ; 30:1, s. 96-103

    • Introduction We aimed to identify clinical factors affecting condition-specific health related quality of life (HRQOL) domains in children born with esophageal atresia (EA). This can facilitate preventive care to risk groups of HRQOL impairments. Materials and Methods A total of 124 Swedish and German families of EA children answered the validated EA-QOL questionnaires (response rate 68%), for evaluation of three HRQOL domains in children 2 to 7 years old (53 parents) and four HRQOL domains in children 8 to 17 years old (62 children/71 parents). Clinical data were collected through medical records and a questionnaire. Statistics included between-group analysis, univariable and stepwise multivariable regression analysis, p < 0.05. Results Between 2 to 7 years, no primary anastomosis ( p = 0.022) and female gender ( p = 0.026) predicted worse scores related to "physical health and treatment," and gastrostomy insertion related to "eating" ( p = 0.0001), and "social isolation and stress" ( p = 0.001). Between 8 to 17 years, no primary anastomosis (child report), prematurity, esophageal dilatation (parent report) predicted poor HRQOL related to "eating" ( p < 0.05), associated anomalies to "body perception" ( p = 0.031, parent report), female gender ( p = 0.018, child report) and severe EA ( p = 0.011 child report, p = 0.004 parent report) to "social relationships," and severe EA predicted worse "health and well-being" scores ( p = 0.004, parent report). An increased number of digestive symptoms (difficulty swallowing food, heartburn, and vomiting), lowered all EA-QOL domain scores in both age groups ( p < 0.001). An increased number of respiratory problems (cough, wheezing, airway infections. breathlessness, and chest tightness), lowered scores in two HRQOL domains among children 2 to 7 years ( p < 0.05). Conclusion Impairments within condition-specific HRQOL domains in EA children are found in congenital and surgical subgroups, and notably related to digestive symptoms throughout childhood.

  • Factors of family impact in a Swedish-German cohort of children born with esophageal atresia
  • 2022
  • Ingår i: Orphanet Journal of Rare Diseases. - : Springer Science and Business Media LLC. - 1750-1172. ; 17:1
  • Tidskriftsartikel (refereegranskat)abstract
    • Background After repair of esophageal atresia (EA), childhood survivors commonly present with digestive and respiratory morbidity, and around 55% have associated anomalies. Although it is known that these problems can reduce health-related quality of life in children with EA, less is understood about the impact on the family. We aimed to identify factors related to family impact in children with EA. Methods One parent each of a child with EA (2-18 years) in 180 families from Sweden and Germany answered the PedsQL (TM) Family Impact Module as the dependent variable. The independent variables were the child's parent-reported health-related quality of life as measured by PedsQL (TM) 4.0, current symptoms, school situation, and parent/family characteristics together with child clinical data from the medical records. Results Stepwise multivariable regression analysis showed a multifactorial model of the total family impact scores (R-2 = 0.60), with independent factors being the child's overall generic health-related quality of life, school-absence >= 1/month, severe tracheomalacia, a family receiving carer's allowance, and a parent with no university/college education, p < 0.05. Logistic regression analysis showed that an increased number of symptoms in the child the preceding 4 weeks lowered the family impact scores; however, the child's feeding (R-2 = 0.35) and digestive symptoms (R-2 = 0.25) explained more in the variation of scores than the child's respiratory symptoms (R-2 = 0.09), p < 0.0001. Conclusions Family functioning may be a contributing factor to the maintenance of child health. The study findings suggest multifactorial explanations to family impact in children with EA, which are essential when optimizing the support to these families in clinical and psychosocial practice. Future research should explore experiences of family impact from all family members' perspectives and multicenter studies are warranted to understand better the effectiveness of psychosocial-educational interventions to families of children with EA.
