MSUD and PKU require lifetime management hence, regular monitoring of amino acid levels is needed to achieve good metabolic control. Ideally, plasma amino acid analysis (PLAA) is used to monitor concentrations but is expensive and not widely available in local laboratories. The newborn screening program in the Philippines uses dried blood spot (DBS) analysis as an alternative where only trained healthcare providers are allowed to perform the collection at selected facilities.

Article Synopsis
  • Hereditary tyrosinemia type I (HT1) is a serious genetic condition that can lead to liver and kidney failure, and can affect the nervous system, but it can be detected early through newborn screening.
  • A study focused on 16 Filipino patients diagnosed with HT1 between 2014 and 2022 found that the average age for starting treatment was just under a month old, with specific biochemical markers like high tyrosine levels indicating the disorder.
  • The most common symptoms observed included issues with blood clotting, elevated alpha fetoprotein levels, and anemia, while the predominant genetic variant found among patients was the homozygous c.122T>C p.Leu41Pro mutation.

In a country where elective termination of pregnancy is not an option, the question arises as to the relevance of this testing, even among health professionals.

Maple syrup urine disease (MSUD) is a rare inborn error of metabolism resulting from a deficiency in the branched-chain alpha-ketoacid dehydrogenase complex. MSUD has been reported to be the most common inborn error of metabolism in the Philippines. We described all patients with maple syrup urine disease patients diagnosed through newborn screening during its first 2 years of implementation and the challenges encountered during their medical management.
