AbstractNewborn screening (NBS) aims toward early detection of treatable congenital disorders. From January 2008 through December 2017, 13,376 newborns were screened for congenital hypothyroidism (CH), congenital adrenal hyperplasia (CAH), and glucose-6-phosphate dehydrogenase (G6PD) deficiency at Sir Ganga Ram Hospital, India, by measuring G6PD activity, thyroid-stimulating hormone, and 17-hydroxyprogesterone on dried blood specimens. The birth prevalence of 1:2,000 for CH, 1:2,500 for CAH, and 1:125 for G6PD deficiency indicates the latter as the most prevalent. Performance evaluation of testing reveals a robust screening program with 100% sensitivity and >99% specificity. Hence, we recommend NBS for early diagnosis and treatment to prevent adverse outcomes.

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.

Abstract Purpose Newborn screening is the need of the hour in a developing country like India as there is paucity of data from studies conducted in government hospitals with large sample size. The purpose of the study is to estimate incidence rate and recall rates for five conditions screened in the neonatal period namely congenital hypothyroidism, congenital adrenal hyperplasia, glucose-6-phosphate dehydrogenase (G6PD) deficiency, galactosemia and phenyl ketonuria (PKU). Methods The study was conducted at VaniVilas Hospital attached to Bangalore Medical College and Research Institute. A retrospective analysis of the results of newborn screening programme during a 3-year period between January 2016 and December 2018 was done. There were 47 623 livebirths during this period out of which 41 027 babies were screened (coverage—86% of total livebirths). Heelprick samples after 48 h of life and prior to discharge were analysed by quantitative assessment. Neonates having positive screening results were recalled by telephonic call for repeat screening and confirmatory tests. Results G6PD deficiency was the most common disorder with an incidence of 1:414, followed by congenital hypothyroidism and Congenital Adrenal Hyperplasia with an incidence of 1:2735 and 1:4102, respectively. Galactosemia and PKU were found to be rare in our population. The overall average recall rate was 0.6% which meant that 24 normal newborns were recalled for testing for one confirmed case. The recall rate was relatively higher for galactosemia and G6PD deficiency which was at 0.25% each compared to the other conditions where it was below 0.05%. Conclusion The results of the study emphasize the need for universal newborn screening especially in all government hospitals with large birth cohorts.

Background. A newborn screening program (NSP) for congenital hypothyroidism (CH) was carried out in Guangxi in order to understand the incidence of CH and the factors interrelated to major types of CH in this region of China. Methods. During 2009 to 2013, data from 930 612 newborns attending NSP in Guangxi were collected. Patients were classified with either permanent CH (PCH) or transient CH (TCH) after 2 years of progressive study. Results. A total of 1210 patients were confirmed with CH with an incidence of 1/769, including 68 PCH and 126 TCH cases with incidences of 1/6673 and 1/3385, respectively. The frequency of thyroid stimulating hormone values greater than 5 mIU/L was 7.2%, which, based on WHO guidelines, suggests that the population was mildly iodine deficient. Conclusions. The incidence of CH was high in Guangxi. Approximately two thirds of CH patients were TCH, which may be due to a deficiency in iodine within the population.

Newborn screening is a successful program in many developed countries. In India, the benefits of dried blood spot screening have been recognized and that screening is slowly gaining traction. There are significant issues standing in the way of universal implementation of a newborn screening program in India: awareness, cost, advocacy, public policy, and politics. Three regional screening programs, Chandigarh, Goa, and Kerala could serve as models for other programs in India. The data for this commentary were based on personal experiences from managing public newborn screening programs, searches on PubMed and Google, and personal interactions with experts in the field. The overwhelming recommendation is to universally screen for congenital hypothyroidism in India, because it is easy and inexpensive to treat, with excellent outcomes. It would also be beneficial to consider screening universally for glucose-6-phosphate dehydrogenase deficiency due to its high incidence and ease of treatment. Finally, sickle cell disease should be screened in those areas in India where it is prevalent due to the costs associated with universal screening. Achieving universal screening is a challenge, and it is very difficult to predict when every baby born in India will be screened for at least congenital hypothyroidism.

Background: Iodine deficiency is associated with goiter and impaired brain function. Neonatal thyroid-stimulating hormone (TSH) screening for congenital hypothyroidism used as an indicator of the degree of iodine deficiency and of its control. An increased frequency of thyroid-stimulating hormone (TSH) measurements above 5 mIU/L in newborn screening corresponds to the impaired iodine status of the population. The aim: to estimate the iodine deficiency and the effectiveness of iodine prophylaxis in Krasnoyarsk territory, Republics of Tuva and Khakassia according the results of neonatal TSH_screening. Methods: An 18-year analysis was performed in 34,980 newborns participating in the national thyroid newborn screening program. The TSH concentration was measured in dry blood spots collected by heel stick on filter paper, 96 hours after birth, using DELFIA method. Results: According to the data of the congenital hypothyroidism screening the rate of TSH < 5 mU/1 was 11.8% in Krasnoyarsk territory (23.9% in 2000) and corresponded to mild iodine deficiency. In different regions of Krasnoyarsk territory the rate of TSH < 5 mU/1 in the newborn varied from 3.5% to 23.7%. The highest values were marked in the Arctic peninsula Taimyr, in cities Zheleznogorsk (nuclear facility) and Sosnovoborsk, in Irbeysky, Suchobuzimsky, Eniseysky, Tuchtetsky, Novoselovsky regions (20.9–23.7%). In the Republic of Khakasia the rate of TSH < 5 mU/1 was 12.5%. In the Republic of Tyva the rate of TSH < 5 mU/1 was – 6.6% (38.6% in 1997; 11.5% in 2000). These results indicate mild iodine deficiency. Conclusion: Our investigations show mild iodine deficiency in Central Siberia demanding continuous adequate iodine prevention. Additional assessment of the iodine intake in the regions with mild iodine deficiency is needed to prevent suboptimal cognitive and psychomotor outcomes.

To the Editor.— We recently have documented a relationship between serum α-fetoprotein (AFP) and congenital hypothyroidism (CH) in the newborn period. Previous studies in our laboratory and others had reported a relationship between elevated serum AFP and elevated thyroid-stimulating hormone (TSH)/low thyroxine T4 in newborns and infants in the first few months of life.1-4 The New York State Newborn Screening Program for CH routinely screens more than 300 000 specimens per year diagnosing 120 to 140 confirmed cases of CH annually.

BACKGROUND: The expanded newborn screening programme has now initiated worldwide. Many of the countries around the world made this programme mandatory. The effect of such screening system gives the advantage or betterment to the society as well as the nation.METHODS: Samples were collected from babies aged 48-72 hours by heel prick method in a filter paper provided by Bio-Rad. The written consent was taken from the parents before collecting the blood samples. Blood samples were assayed for TSH and17-OHP by Enzyme Immuno Assay (EIA), G-6-PD was estimated by colorimetric assay provided by Bio-Rad Laboratories, USA and Sickle Cell Disease by sickling testRESULTS: A total of 715 newborns were screened for TSH, G-6-PD, 17-OHP and Sickle cell disease. Out of which 1 neonate found abnormal (increased) thyroid stimulating hormone (1/715), and 8 neonates were G-6-PD deficient (8/715). We did not find any cases of congenital adrenal hyperplasia and sickle cell disease.CONCLUSIONS: In this study the prevalence of Congenital Hypothyroidism and Glucose-6-Phosphate dehydrogenase deficiency was found to be 1:715 and 1:89 respectively. No cases of congenital adrenal hyperplasia and sickle cell disease were found.
