United Arab Emirates National Newborn Screening Programme: an evaluation 1998-2000

Area of Science:

• Public Health
• Pediatrics
• Genetics

Background:

• Newborn screening is crucial for early detection of metabolic and endocrine disorders.
• The United Arab Emirates (UAE) National Newborn Screening Programme aims to identify conditions like phenylketonuria (PKU) and congenital hypothyroidism (CH).

Purpose of the Study:

• To evaluate the UAE National Newborn Screening Programme's performance against international standards.
• Key indicators assessed include coverage, timeliness, and specimen quality.
• Specific disease detection rates for PKU and CH were calculated.

Main Methods:

• Comparison of programme indicators (age at sampling, recall, treatment initiation, specimen delivery, lab results) with international benchmarks.
• Calculation of recall rate, sensitivity, specificity, and positive predictive values for PKU and CH.
• Diagnostic investigations included thyroid function tests, PKU amino acid analysis, and biopterin defect testing.

Main Results:

• Over 138,000 neonates were screened in the 6 years prior to December 2000.
• Relative incidence rates were 1:1570 for congenital hypothyroidism (CH) and 1:20,050 for classic phenylketonuria (PKU).
• Programme coverage, timeliness, and specimen quality were assessed against global standards.

Conclusions:

• The UAE National Newborn Screening Programme demonstrates effective performance in terms of coverage and timeliness.
• The programme successfully identifies critical conditions like CH and PKU, enabling timely intervention.
• Findings support the programme's alignment with international standards for newborn health surveillance.
