Current Status of Newborn Bloodspot Screening Worldwide 2024: A Comprehensive Review of Recent Activities (2020-2023). Int J Neonatal Screen 2024; 10:38. [PMID: 38920845 PMCID: PMC11203842 DOI: 10.3390/ijns10020038] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/06/2024] [Revised: 03/28/2024] [Accepted: 03/28/2024] [Indexed: 06/27/2024] Open
Abstract
Newborn bloodspot screening (NBS) began in the early 1960s based on the work of Dr. Robert "Bob" Guthrie in Buffalo, NY, USA. His development of a screening test for phenylketonuria on blood absorbed onto a special filter paper and transported to a remote testing laboratory began it all. Expansion of NBS to large numbers of asymptomatic congenital conditions flourishes in many settings while it has not yet been realized in others. The need for NBS as an efficient and effective public health prevention strategy that contributes to lowered morbidity and mortality wherever it is sustained is well known in the medical field but not necessarily by political policy makers. Acknowledging the value of national NBS reports published in 2007, the authors collaborated to create a worldwide NBS update in 2015. In a continuing attempt to review the progress of NBS globally, and to move towards a more harmonized and equitable screening system, we have updated our 2015 report with information available at the beginning of 2024. Reports on sub-Saharan Africa and the Caribbean, missing in 2015, have been included. Tables popular in the previous report have been updated with an eye towards harmonized comparisons. To emphasize areas needing attention globally, we have used regional tables containing similar listings of conditions screened, numbers of screening laboratories, and time at which specimen collection is recommended. Discussions are limited to bloodspot screening.

[PMID: 37539282 PMCID: PMC10393755 DOI: 10.1016/j.heliyon.2023.e18437] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/08/2023] [Revised: 07/12/2023] [Accepted: 07/18/2023] [Indexed: 08/05/2023] Open
Abstract
Background Glucose-6-phosphate dehydrogenase (G6PD) deficiency is a genetic disorder caused by a structural abnormality in the enzyme. G6PD deficiency is most prevalent among African, Asian, and Mediterranean people. This study aimed to investigate how prevalent G6PD deficiency is in African neonates with jaundice. Methods The public sources, such as PubMed, Science Direct, Google Scholar, and Africa Journal Online were searched for articles that reported the prevalence of G6PD deficiency published before March 21st, 2022. The Joanna Briggs Institute's (JBI) critical assessment checklist was used to evaluate the quality of individual studies. STATA-17 was used to do the statistical analysis. The pooled prevalence of G6PD deficiency in neonates with jaundice in Africa was calculated using a forest plot and a random effects model. I2 statistics and Galbraith plots were used to assess heterogeneity. Publication bias was assessed using a funnel plot and Egger's statistical test. Results Ten studies involving 1555 neonates with jaundice were involved in the study. G6PD deficiency was prevalent in 24.60% of African neonates with jaundice (95% CI:12.47-36.74) with considerable heterogeneity (I2 = 100%). Nigerian neonates with jaundice had the highest G6PD deficiency (49.67%), whereas South Africans had the lowest (3.14%). Conclusion G6PD deficiency has been implicated in a significant portion of African neonates with jaundice, notwithstanding the need for greater research on predisposing variables from other countries. Therefore, it should be thought of performing screening and diagnostic laboratory tests for G6PD deficiency.

Performance of a Commercial Multiplex Allele-Specific Polymerase Chain Reaction Kit to Genotype African-Type Glucose-6-Phosphate Dehydrogenase Deficiency. Am J Trop Med Hyg 2023; 108:449-455. [PMID: 36535256 PMCID: PMC9896312 DOI: 10.4269/ajtmh.21-1081] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/12/2021] [Accepted: 02/03/2022] [Indexed: 12/23/2022] Open
Abstract
8-Aminoquinoline antimalarial drugs (primaquine, tafenoquine) are required for complete cure of Plasmodium vivax malaria, but they are contraindicated in patients with glucose-6-phosphate dehydrogenase (G6PD) deficiency. In the absence of spectrophotometry, which is a gold standard for measuring G6PD activity, G6PD genotyping is one of the alternatives to establish a database and distribution map of G6PD enzyme deficiency in Mauritania, which has become a new epicenter of P. vivax malaria in West Africa. The aim of our study was to assess the performance of multiplex allele-specific polymerase chain reaction (PCR) (African-type Diaplex C™ G6PD kit) against PCR-restriction fragment length polymorphism and sequencing. Of 146 mutations associated with G6PD A- genotypes in 177 blood samples from Mauritanian patients, all but two samples were identified correctly using multiplex allele-specific PCR (100% sensitivity and 99% specificity; "almost perfect agreement" between allele-specific PCR and PCR-restriction fragment length polymorphism/sequencing, with a kappa coefficient of 0.977). Despite a suboptimal PCR protocol for dried blood spots and the inability of the commercial assay to predict unequivocally the G6PD enzyme level in heterozygous females, the African-type Diaplex C™ G6PD genotyping kit seemed to be a valuable screening tool for male subjects and for research purposes in resource-limited countries where spectrophotometer and DNA sequencing are not available.

Abstract
Glucose-6-phosphate dehydrogenase (G6PD) deficiency caused by genetic variants in the G6PD gene, constitutes the most common enzymopathy worldwide, affecting approximately 5% of the global population. While carriers are mostly asymptomatic, they are at substantial risk of acute hemolytic anemia upon certain infections or exposure to various medications. As such, information about G6PD activity status in a given patient can constitute an important parameter to guide clinical decision-making. Here, we leveraged whole genome sequencing data from 142,069 unrelated individuals across seven human populations to provide a global comprehensive map of G6PD variability. By integrating established functional classifications with stringent computational predictions using 13 partly orthogonal algorithms for uncharacterized and novel variants, we reveal the large extent of ethnogeographic variability in G6PD deficiency and highlight its population-specific genetic composition. Overall, estimated disease prevalence in males ranged between 12.2% in Africans, 2.7-3.5% across Asia and 2.1% in Middle Easterners to < 0.3% in Europeans, Finnish and Amish. In Africans, the major deficient alleles were A-202A/376 G (minor allele frequency 11.6%) and A-968 C/376 G (0.5%). In contrast, G6PD deficiency in Middle Easterners was primarily due to the Mediterranean allele (1.3%) and the population-specific Cairo variant (0.4%). In South Asia, the most prevalent deficient alleles were Mediterranean (1.7%), Kerala (1.1%), Gond (0.9%) and Orissa (0.2%), whereas in East Asian populations the Canton (1.1%), Kaiping (0.7%) and Viangchan (0.3%) variants were predominant. Combined, our analyses provide a large dataset of G6PD variability across major ethnogeographic groups and can instruct population-specific genotyping strategies to optimize genetically guided therapeutic interventions.

Assessment of CareStart G6PD rapid diagnostic test and CareStart G6PD biosensor in Mauritania. Infect Dis Poverty 2021; 10:105. [PMID: 34353361 PMCID: PMC8340529 DOI: 10.1186/s40249-021-00889-2] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/19/2021] [Accepted: 07/19/2021] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND The elimination of Plasmodium vivax malaria requires 8-aminoquinolines, which are contraindicated in patients with glucose-6-phosphate dehydrogenase (G6PD) deficiency due to the risk of acute haemolytic anaemia. Several point-of-care devices have been developed to detect G6PD deficiency. The objective of the present study was to evaluate the performance of two of these devices against G6PD genotypes in Mauritania. METHODS Outpatients were screened for G6PD deficiency using CareStart™ rapid diagnostic test (RDT) and CareStart™ G6PD biosensor in Nouakchott, Mauritania, in 2019-2020. African-type and Mediterranean-type G6PD genotypes commonly observed in Africa were determined by polymerase chain reaction-restriction fragment length polymorphism and sequencing. Qualitative variables were compared using Fisher's exact test. RESULTS Of 323 patients (74 males and 249 females), 5 males and 2 homozygous females had the African-type A- genotype: A-(202) in 3 males and 2 females and G6PD A-(968) in 2 males. Among heterozygous females, 13 carried G6PD A-(202), 12 G6PD A-(968), and 3 G6PD A-(542) variants. None had the Mediterranean-type G6PD genotype. Eight had a positive G6PD RDT result, including all 7 hemizygous males and homozygous females with A- or A-A- (0.12 to 2.34 IU/g haemoglobin, according to G6PD biosensor), but RDT performed poorly (sensitivity, 11.1% at the cut-off level of < 30%) and yielded many false negative tests. Thirty-seven (50.0%) males and 141 (56.6%) females were anaemic. The adjusted median values of G6PD activity were 5.72 and 5.34 IU/g haemoglobin in non-anaemic males (n = 35) and non-anaemic males and females (n = 130) with normal G6PD genotypes using G6PD biosensor, respectively. Based on the adjusted median of 5.34 IU/g haemoglobin, the performance of G6PD biosensor against genotyping was as follows: at 30% cut-off, the sensitivity and specificity were 85.7% and 91.7%, respectively, and at 80% cut-off, the sensitivity was 100% while the specificity was 64.9%. CONCLUSIONS Although this pilot study supports the utility of biosensor to screen for G6PD deficiency in patients, further investigation in parallel with spectrophotometry is required to promote and validate a more extensive use of this point-of-care device in areas where P. vivax is highly prevalent in Mauritania.
