Cardiorespiratory performance capacity and airway microbiome in patients following primary repair of esophageal atresia.

ABSTRACT:

Background

Patients following repair of an esophageal atresia (EA) or tracheoesophageal fistula (TEF) carry an increased risk of long-term cardiopulmonary malaise. The role of the airway microbiome in EA/TEF patients remains unclear.

Methods

All EA/TEF patients treated between 1980 and 2010 were invited to a prospective clinical examination, spirometry, and spiroergometry. The airway microbiome was determined from deep induced sputum by 16 S rRNA gene sequencing. The results were compared to a healthy age- and sex-matched control group.

Results

Nineteen EA/TEF patients with a mean age of 24.7 ± 7 years and 19 age- and sex-matched controls were included. EA/TEF patients showed a significantly lower muscle mass, lower maximum vital capacity (VC_max), and higher rates of restrictive ventilation disorders. Spiroergometry revealed a significantly lower relative performance capacity and lower peak VO₂ in EA/TEF patients. Alpha- and beta-diversity of the airway microbiome did not differ significantly between the two groups. Linear discriminant effect size analysis revealed significantly enriched species of Prevotella_uncultured, Streptococcus_anginosus, Prevotella_7_Prevotella_enoeca, and Mogibacterium_timidum.

Conclusion

EA/TEF patients frequently suffer from restrictive ventilation disorders and impaired cardiopulmonary function associated with minor alterations of the airway microbiome. Long-term examinations of EA/TEF patients seem to be necessary in order to detect impaired cardiopulmonary function.

Impact

The key messages of the present study are a significantly decreased VC_max and exercise performance, as well as airway microbiome differences in EA/TEF patients. This study is the first to present parameters of lung function and exercise performance in combination with airway microbiome analysis with a mean follow-up of 24 years in EA/TEF patients. Prospective, long-term studies are needed to unravel possible interactions between alterations of the airway microbiome and impaired pulmonary function in EA/TEF patients.

Project description:BackgroundChildren with long-gap esophageal atresia (LGEA) risk living with aerodigestive morbidity and mental health difficulties. No previous study has investigated their experiences of schooling, despite the importance of schools in children's development, learning and social relationships. We aimed to describe experiences of schooling in children with LGEA in Sweden in comparison with children with EA who had primary anastomosis.MethodChildren with LGEA aged 3-17 were recruited nationwide in Sweden. One parent completed a survey on their child's school-based supports (according to definitions from the Swedish National Agency for Education), school absence, school satisfaction, school functioning (PedsQL 4.0), mental health (Strength and Difficulties Questionnaire) and current symptomatology. School data were compared between 26 children with LGEA to that from 95 children with EA who had PA, a hypothesized milder affected group. Mental health level was determined using validated norms; abnormal ≥ 90 percentile. Data were analyzed using descriptives, correlation and Mann-Whitney-U test. Significance level was p < 0.05.ResultsFormal school-based support was reported in 17 (65.4%) children with LGEA and concerned support with nutritional intake (60%), education (50%) and medical/special health needs (35%). The prevalence of school-based support was significantly higher compared to children with PA overall (36.8%, p = 0.013) and regarding nutritional intake support (20%, p < 0.001). In children with LGEA, school-based support was related to low birth weight (p = 0.036), young child age (p = 0.014), height ≤ -2SD for age/sex (p = 0.024) and an increased number of aerodigestive symptoms (p < 0.05). All children with LGEA who had abnormal mental health scores had school-based support, except for one child. Nine children with LGEA (36%) had school absence ≥ 1times/month the past year, more frequently because of colds/airway infections (p = 0.045) and GI-specific problems compared to PA (p = 0.003). School functioning scores were not significantly different from children with PA (p = 0.34) but correlated negatively with school-based support (< 0.001) and school absence (p = 0.002). One parent out of 26 reported their child's school satisfaction as "not good".ConclusionsChildren with LGEA commonly receive school-based support, reflecting multifaceted daily needs and disease severity. School absence is frequent and related to poorer school functioning. Future research focusing on academic achievement in children with EA is needed.
