X-linked adrenoleukodystrophy (ALD) is a recent addition to the Recommended Uniform Screening Panel, prompting many states to begin screening newborns for the disorder. We provide California’s experience with ALD newborn screening, highlighting the clinical and epidemiological outcomes observed as well as program implementation challenges. In this retrospective cohort study, we examine ALD newborn screening results and clinical outcomes for 1,854,631 newborns whose specimens were received by the California Genetic Disease Screening Program from 16 February 2016 through 15 February 2020. In the first four years of ALD newborn screening in California, 355 newborns screened positive for ALD, including 147 (41%) with an ABCD1 variant of uncertain significance (VUS) and 95 males diagnosed with ALD. After modifying cutoffs, we observed an ALD birth prevalence of 1 in 14,397 males. Long-term follow-up identified 14 males with signs of adrenal involvement. This study adds to a growing body of literature reporting on outcomes of newborn screening for ALD and offering a glimpse of what other large newborn screening programs can expect when adding ALD to their screening panel.

Screening Strategies

Congenital hypothyroidism (CH) is the most common preventable cause of intellectual impairment or failure to thrive by early identification and treatment. In Japan, newborn screening programs for CH were introduced in 1979, and the clinical guidelines for newborn screening of CH were developed in 1998, revised in 2014, and are currently undergoing further revision. Newborn screening strategies are designed to detect the elevated levels of thyroid stimulating hormone (TSH) in most areas of Japan, although TSH and free thyroxine (FT4) are often measured simultaneously in some areas. Since 1987, in order not to observe the delayed rise in TSH, additional rescreening of premature neonates and low birth weight infants (<2000 g) at four weeks of life or when their body weight reaches 2500 g has been recommended, despite a normal initial newborn screening. Recently, the actual incidence of CH has doubled to approximately 1:2500 in Japan as in other countries. This increasing incidence is speculated to be mainly due to an increase in the number of mildly affected patients detected by the generalized lowering of TSH screening cutoffs and an increase in the number of preterm or low birth weight neonates at a higher risk of having CH than term infants.

IntroductionDecision making regarding national population-based prenatal and newborn screening policies is recognized to be highly challenging. This paper aims to describe the formalized collaboration that has been established between the Spanish National Public Health Screening Advisory Committee (PHSAC) and the Spanish Network of Health Technology Assessment (HTA) agencies to support the development of evidence- and consensus-based recommendations to support this process.MethodsIn-depth description and analysis of the strategic and methodological processes that have been implemented within the Spanish National Health System prenatal and newborn screening frameworks, with special emphasis on the role, actions, and responsibilities of HTA agencies.ResultsThe role of HTA agencies is threefold: (i) support the PHSAC by providing evidence on safety, effectiveness and cost/effectiveness of the screening tests/strategies, as well as contextualized information regarding costs, organizational, social, legal and ethical issues; (ii) collaborate with the PHSAC in the development of formal evidence- and consensus-based recommendations for defining population screening programs, when required; (iii) analyze real-world data that is generated by piloted programs. This paper will provide real-life examples of how these processes were implemented in practice, with a special focus on the development of the non-invasive prenatal testing (NIPT) policy. Recommendations for NIPT were developed by a multidisciplinary group based on the European network for Health Technology Assessment (EUnetHTA) rapid assessment report and the predictive models that were built using national statistics and other contextualized data.ConclusionsThe current work represents an innovative approach for prenatal and newborn screening policymaking, which are commonly difficult to evaluate due to the low quality of evidence and the confounding public health issues. The paper raises awareness regarding the importance of joint collaborations in areas where evidence is commonly insufficient for decision making.

AbstractNewborn screening comprises a paramount public health program seeking timely detection, diagnosis, and intervention for genetic disorders that may otherwise produce serious clinical consequences. Today newborn screening is part of the health care system of developed countries, whereas in India, newborn screening is still in the toddler stage.We searched PubMed with the keywords newborn screening for metabolic disorders, newborn screening in India, and congenital disorder in neonates, and selected publications that seem appropriate.In India, in spite of the high birth rate and high frequency of metabolic disorders, newborn screening programs are not part of the health care system. At Union Territory, Chandigarh in 2007, newborn screening was initiated and is currently ongoing for three disorders, that is, congenital hypothyroidism, congenital adrenal hyperplasia, and glucose-6-phosphate dehydrogenase (G6PD) deficiency. Prevalence of these disorders is found to be 1:1400 for congenital hypothyroidism, 1:6334 for congenital adrenal hyperplasia, and 1:80 for G6PD deficiency.Mandatory newborn screening for congenital hypothyroidism should be implemented in India, and other disorders can be added in the screening panel on the basis of region-wise prevalence. The objective of this review is to provide insight toward present scenario of newborn screening in India along with recommendations to combat the hurdles in the pathway of mandatory newborn screening.

These are heady times for newborn screening. Articles in the medical literature and speakers at grand rounds urge us to test babies for disorders, including cystic fibrosis,1 biotinidase deficiency,2 and medium-chain acyl coenzyme A dehydrogenase deficiency.3 States are expanding the batteries of tests they perform. My own state of Tennessee just began testing neonates for galactosemia this year. And this is no doubt just the beginning. New techniques are being developed that will make it possible to look for a host of genetic characteristics using microscopic amounts of blood. We soon may be able to discern many conditions and characteristics of our children.

Overwhelming Evidence

In Reply.— Wyatt makes two points regarding the vulnerability of newborn screening programs but only one, in my opinion, has serious implications. With regard to the first, that the pitfalls might be used as an excuse to curtail screening programs seems unlikely. The overwhelming evidence accumulated from all programs involved in neonatal screening indicates that despite the occasional missed case, without such programs, the damage to children and their families would have been incalculable. Faced with this evidence few would have the temerity to attempt to discredit the value of screening programs or limit their involvement in health care.

Maternal Thyroid

Congenital hypothyroidism (CH) represents one of the most common preventable causes of mental retardation. The fetal hypothalamic-pituitary-thyroid axis begins to function by midgestation and is mature in the term infant at delivery. If fetal hypothyroidism develops, untoward effects may be demonstrated in certain organ systems, including the central nervous system and skeleton. However, most infants with CH appear normal at birth. Recent data suggest that the hypothyroid fetus is protected to a certain extent by placental transfer of maternal thyroid hormone; serum thyroxine (T4) levels in the cord blood of athyroid fetuses approximate one third of maternal levels.1 In addition, studies in animal models of hypothyroidism demonstrate increased levels of brain iodothyronine deiodinase, the enzyme which converts T4 to triiodothyronine (T3). In the hypothyroid fetus, this increased enzyme acting on T4 of maternal origin is sufficient to produce near normal fetal brain T3 concentrations.2 Thus, it appears that early detection and treatment of congenital hypothyroidism should have the potential to completely reverse the effects of fetal hypothyroidism in all but the most severe cases, for example, athyreotic infants born to mothers with thyroid problems resulting in inadequate placental transfer of maternal thyroid hormone. Since the development of pilot screening programs for CH in Quebec and Pittsburgh in 1974,3 newborn screening for CH has become routine in essentially all developed countries of the world and is under development in Eastern Europe, South America, Asia, and Africa. In North America it is estimated that more than 5 million newborns are screened, with approximately 1400 infants with congenital hypothyroidism detected annually.

Current Screening

These newborn screening fact sheets were developed by the Committee on Genetics of the American Academy of Pediatrics (AAP) with considerable assistance and consultation from many individuals. It is hoped that the information contained in these fact sheets will assist the pediatrician in understanding the individual tests, their characteristics, and their strengths and weaknesses. Newborn screening is an individual function of each state; therefore, screening programs are not uniform throughout the United States (Table). Because the test results can affect children and parents in a variety of ways, there are special concerns about how states make decisions to adopt new tests and how they evaluate their current screening panels. Currently, many states are examining their practices. The informatiion in the fact sheets was not designed to advocate specific newborn screening tests but to assist pediatricians in evaluating policies and procedures and in developing appropriate positions based on the needs of their patients and their geographic regions.

Overall Mortality

Newborn screening for sickle cell disease has been recommended as a method of decreasing patient mortality. However, its effectiveness in accomplishing this has not been reliably measured. To help determine the effectiveness, 10 years of experience in newborn screening have been summarized. The effects of early patient enrollment in a comprehensive treatment program on long-term morbidity and mortality are reported. From 1975 to 1985, 84,663 newborns were screened regardless of race or ethnic background. Bart's hemoglobin was present in 5%, hemoglobin AS in 2.6%, and hemoglobin AC in 0.75%. Excluding Bart's, approximately 3.6% of all newborns were carriers for hemoglobinopathy. Sickle cell disease occurred in 1:951 births (58 hemoglobin SS, 25 hemoglobin FSC, three hemoglobin S-β+-thalassemia, and three hemoglobin S-β°-thalassemia). In addition, one in every 4,233 newborns had a clinically significant thalassemia syndrome (eight hemoglobin FE, ten hemoglobin F only, two hemoglobin H). Compared with other newborn screening programs in California, (congenital hypothyroidism, 1:3,849; phenylketonuria 1:22,474, galactosemia 1:74,103), hemoglobinopathies are the most prevalent congenital disease. Eighty-one newborns with sickle cell disease were followed for 7.2 years. Patients experienced 513 hospitalizations, including 13 episodes of sepsis with or without meningitis and ten acute sequestration crises. The overall mortality rate for patients with sickle cell anemia diagnosed in the newborn period was 1.8%. In comparison, the clinical course of 64 patients with sickle cell anemia diagnosed after 3 months of age and followed for an average of 9.4 years was analyzed. Five of these patients died. In two of these, sickle cell anemia was diagnosed at the time of the death. Overall mortality rate in this group was 8%. In summary, the data indicate that newborn screening, when coupled with extensive follow-up and education, will significantly decrease patient mortality.
