Infant lung function and early skin barrier impairment in the development of asthma at age 3 years.

BACKGROUND: Largely unexplored, we investigated if lower lung function, impaired skin barrier function by transepidermal water loss (TEWL), eczema, and filaggrin (FLG) mutations in infancy were associated with asthma in early childhood. METHODS: From the factorially designed randomized controlled intervention study PreventADALL, we evaluated 1337/2394 children from all randomization groups with information on asthma at age 3 years, and at age 3 months either lung function, TEWL, eczema, and/or FLG mutations. Lower lung function was defined as the time to peak tidal expiratory flow to expiratory time (tPTEF /tE ) <0.25, and skin barrier impairment as a high TEWL >9.50 g/m2 /h. Eczema was clinically observed, and DNA genotyped for FLG mutations. Asthma was defined as asthma-like symptoms (≥3 episodes of bronchial obstruction) between age 2-3 years as well as a history of doctor-diagnosed asthma and/or asthma medication use. Associations were analyzed in logistic regression models, presented with adjusted ORs (aOR) and 95% confidence intervals (CI). RESULTS: Lower lung function and skin barrier impairment were associated with asthma in general; aOR (95% CI) 5.4 (2.1, 13.7) and 1.6 (1.1, 2.5), while eczema and FLG mutations were associated with asthma in children with atopic dermatitis or allergic sensitization only. Stratifying for sex, the risk of asthma was only increased in boys with lower lung function; aOR (95% CI) 7.7 (2.5, 23.6), and in girls with FLG mutations; aOR (95% CI) 3.5 (1.5, 8.2). CONCLUSION: Lower lung function and impaired skin barrier function in infancy may increase the risk of asthma at age 3 years.

The impact of diagnosed fetal anomaly, diagnostic severity and prognostic ambiguity on parental depression and traumatic stress: a prospective longitudinal cohort study.

INTRODUCTION: The detection of a fetal anomaly during routine obstetric ultrasound is a potentially traumatic experience. The aim of this study is to examine longitudinally the impact of diagnosis of fetal anomaly on symptoms of depression and traumatic stress among mothers and fathers, and to examine how variations in psychological adjustment relate to diagnostic severity and prognostic ambiguity. MATERIAL AND METHODS: In this prospective observational study conducted at a tertiary perinatal referral center, 81 mothers and 69 fathers with ultrasound findings of fetal anomaly completed the Edinburgh Postnatal Depression Scale (EPDS) and Impact of Events Scale (IES) at four time points in pregnancy (T1-T4) and 6 weeks after birth (T5). We compared this with depression and traumatic stress in a sample of non-affected parents (n = 110 mothers, 98 fathers). RESULTS: Linear mixed effects models indicated that parents who received a diagnosis of fetal anomaly experienced higher levels of depression and traumatic stress over time, compared with non-affected parents. Depression: mean difference mothers = 4.46 ± 0.47, fathers = 2.80 ± 0.42. Traumatic stress: mean difference mothers = 20.04 ± 2.13, fathers = 12.66 ± 1.74. Parents with a more severe diagnosis experienced elevated symptoms compared with parents with a less severe diagnosis. Among mothers, prognostic ambiguity and changes in the anticipated diagnosis after birth were also associated with increased distress, regardless of whether the change was for the better or worse. CONCLUSIONS: Diagnosis of fetal anomaly increases risk of depression and traumatic stress in expectant mothers and fathers, both acutely and over time.

Paternal psychological response after ultrasonographic detection of structural fetal anomalies with a comparison to maternal response: a cohort study.

BACKGROUND: In Norway almost all pregnant women attend one routine ultrasound examination. Detection of fetal structural anomalies triggers psychological stress responses in the women affected. Despite the frequent use of ultrasound examination in pregnancy, little attention has been devoted to the psychological response of the expectant father following the detection of fetal anomalies. This is important for later fatherhood and the psychological interaction within the couple. We aimed to describe paternal psychological responses shortly after detection of structural fetal anomalies by ultrasonography, and to compare paternal and maternal responses within the same couple. METHODS: A prospective observational study was performed at a tertiary referral centre for fetal medicine. Pregnant women with a structural fetal anomaly detected by ultrasound and their partners (study group,n=155) and 100 with normal ultrasound findings (comparison group) were included shortly after sonographic examination (inclusion period: May 2006-February 2009). Gestational age was >12 weeks. We used psychometric questionnaires to assess self-reported social dysfunction, health perception, and psychological distress (intrusion, avoidance, arousal, anxiety, and depression): Impact of Event Scale. General Health Questionnaire and Edinburgh Postnatal Depression Scale. Fetal anomalies were classified according to severity and diagnostic or prognostic ambiguity at the time of assessment. RESULTS: Median (range) gestational age at inclusion in the study and comparison group was 19 (12-38) and 19 (13-22) weeks, respectively. Men and women in the study group had significantly higher levels of psychological distress than men and women in the comparison group on all psychometric endpoints. The lowest level of distress in the study group was associated with the least severe anomalies with no diagnostic or prognostic ambiguity (p < 0.033). Men had lower scores than women on all psychometric outcome variables. The correlation in distress scores between men and women was high in the fetal anomaly group (p < 0.001), but non-significant in the comparison group. CONCLUSION: Severity of the anomaly including ambiguity significantly influenced paternal response. Men reported lower scores on all psychometric outcomes than women. This knowledge may facilitate support for both expectant parents to reduce strain within the family after detectionof a fetal anomaly.
