The impacts of adrenoleukodystrophy newborn screening on the evaluation of adrenal dysfunction in male children: An integrative literature review.

PROBLEM: Adrenoleukodystrophy (ALD) is an x-linked genetic condition with a high risk of adrenal dysfunction recommended for newborn screening. This review aims to critically appraise and synthesize existing literature identifying the impacts of ALD newborn screening in the United States on the evaluation and treatment of adrenal dysfunction in male children.

ELIGIBILITYCRITERIA: An integrative literature review was conducted using the Embase, PubMed, and CINAHL databases. English-language primary source studies published in the past decade and seminal studies were included.

SAMPLE: Twenty primary sources met the inclusion criteria, including five seminal studies.

RESULTS

Three major themes emerged from the review: 1) prevention of adrenal crisis, 2) unexpected outcomes, and 3) ethical impacts.

CONCLUSIONS

ALD screening increases disease identification. Serial adrenal evaluation prevents adrenal crisis and death; data is needed to establish predictive outcomes in ALD prognosis. Disease incidence and prognosis will become more apparent as states increasingly add ALD screening to their newborn panel.

IMPLICATIONS FOR PRACTICE: Clinicians need awareness of ALD newborn screening and state screening protocols. Families first learning of ALD through newborn screening results will require education, support, and timely referrals for appropriate care.
