Lin HC, Kasi N, Quiros JA. Alpha1-Antitrypsin Deficiency: Transition of Care for the Child With AAT Deficiency into Adulthood. Curr Pediatr Rev 2019; 15:53-61. [PMID: 30421678 PMCID: PMC6696823 DOI: 10.2174/1573396314666181113094517] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/27/2018] [Revised: 10/02/2018] [Accepted: 11/06/2018] [Indexed: 11/22/2022]
Abstract
IMPORTANCE Alpha1-antitrypsin (AAT) deficiency is a common, but an underdiagnosed genetic condition, affecting 1 in 1500 individuals. It can present insidiously with liver disease in children. Although clinical practice guidelines exist for the management of AAT deficiency, especially with regards to pulmonary involvement, there are no published recommendations that specifically relate to the management of the liver disease and monitoring for lung disease associated with this condition, particularly in children. OBJECTIVE To review the literature on the management of AAT deficiency-associated liver disease in adults and children. EVIDENCE REVIEW A systematic search for articles indexed in PubMed and published was undertaken. Some earlier selected landmark references were included in the review. Search terms included: "alpha1-antitrypsin deficiency"; "liver disease"; "end-stage liver disease"; "liver transplantation" and "preventative management". Recommendations for the management of children with suspected or confirmed AAT deficiency were made according to the Strength of Recommendation Taxonomy scale. FINDINGS Liver complications arising from AAT deficiency result from the accumulation of mutated AAT protein within hepatocytes. Liver disease occurs in 10% of children, manifested by cholestasis, pruritus, poor feeding, hepatomegaly, and splenomegaly, but the presentation is highly variable. A diagnostic test for AAT deficiency is recommended for these children. Baseline liver function tests should be obtained to assess for liver involvement; however, the only curative treatment for AAT deficiency-associated liver disease is organ transplantation. Conclusion and Relevance: There should be a greater vigilance for AAT deficiency testing among pediatricians. Diagnosis should prompt assessment of liver involvement. Children with AATdeficiency- associated liver disease should be referred to a liver specialist and monitored throughout their lifetimes for the symptoms of AAT-deficiency-related pulmonary involvement.

Lim Q, McGill BC, Quinn VF, Tucker KM, Mizrahi D, Patenaude AF, Warby M, Cohn RJ, Wakefield CE. Parents' attitudes toward genetic testing of children for health conditions: A systematic review. Clin Genet 2017; 92:569-578. [PMID: 28170090 DOI: 10.1111/cge.12989] [Citation(s) in RCA: 28] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/04/2016] [Revised: 01/31/2017] [Accepted: 02/01/2017] [Indexed: 12/13/2022]
Abstract
This review assessed parents' attitudes toward childhood genetic testing for health conditions, with a focus on perceived advantages and disadvantages. We also evaluated the factors that influence parents' attitudes toward childhood genetic testing. We searched Medline, Medline In-Process, EMBASE, PsycINFO, Social Work Abstracts and CINAHL. We screened 945 abstracts and identified 21 studies representing the views of 3934 parents. Parents reported largely positive attitudes toward childhood genetic testing across different genetic tests with varying medical utility. Parents perceived a range of advantages and disadvantages of childhood genetic testing. Childhood genetic testing was viewed by most as beneficial. Parents' education level, genetic status, sex and sociodemographic status were associated with reported attitudes. This yielded some conflicting findings, indicating the need for further research. Genetic counseling remains essential to support this population in making well-informed decisions. Targeted interventions tailored to specific families with different sociodemographic characteristics may be useful. Further research on the long-term impact of childhood genetic testing on families is warranted.

Genetic testing of children for predisposition to mood disorders: anticipating the clinical issues. J Genet Couns 2014; 23:566-77. [PMID: 24651919 PMCID: PMC4090807 DOI: 10.1007/s10897-014-9710-y] [Citation(s) in RCA: 9] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/30/2013] [Accepted: 03/05/2014] [Indexed: 12/02/2022]
Abstract
Large-scale sequencing information may provide a basis for genetic tests for predisposition to common disorders. In this study, participants in the Coriell Personalized Medicine Collaborative (N = 53) with a personal and/or family history of Major Depressive Disorder or Bipolar Disorder were interviewed based on the Health Belief Model around hypothetical intention to test one’s children for probability of developing a mood disorder. Most participants (87 %) were interested in a hypothetical test for children that had high (“90 %”) positive predictive value, while 51 % of participants remained interested in a modestly predictive test (“20 %”). Interest was driven by beliefs about effects of test results on parenting behaviors and on discrimination. Most participants favored testing before adolescence (64 %), and were reluctant to share results with asymptomatic children before adulthood. Participants anticipated both positive and negative effects of testing on parental treatment and on children’s self-esteem. Further investigation will determine whether these findings will generalize to other complex disorders for which early intervention is possible but not clearly demonstrated to improve outcomes. More information is also needed about the effects of childhood genetic testing and sharing of results on parent–child relationships, and about the role of the child in the decision-making process.

Nicholls SG, Southern KW. Parental decision-making and acceptance of newborn bloodspot screening: an exploratory study. PLoS One 2013; 8:e79441. [PMID: 24265771 PMCID: PMC3827133 DOI: 10.1371/journal.pone.0079441] [Citation(s) in RCA: 17] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/19/2013] [Accepted: 09/23/2013] [Indexed: 01/28/2023] Open
Abstract
Objective Newborn bloodspot screening is an internationally established public health measure. Despite this, there is a paucity of information relating to the decision-making process that parents go through when accepting newborn screening. This is important as screening panels are expanding; potentially leading to an increasing amount of complex information. This study sought to understand the factors that influence parental decisions and roles they play in the decision-making process. Patients and Methods Qualitative thematic evaluation of semi structured interviews with parents whose children had recently undergone newborn screening in the Merseyside and Cheshire region of England, UK. Results Eighteen interviews with first time parents (n = 12) and those with previous children (n = 6). Seven factors were identified as being either explicitly or implicitly related to parental decision-making: Experience, Attitudes to medicine, Information-seeking behaviour, Perceived knowledge, Attitudes to screening, and Perceived choice, all of which ultimately impact on Perceived decisional quality. Conclusions These results indicate that while content is important, other contextual factors such as personal experience, perceived choice, and general attitudes toward medicine, are also highly influential. In particular, relationships with key healthcare professionals are central to information collection, attitudes toward screening, and the level of deliberation that is invested in decisions to accept newborn bloodspot screening.
