A Five-Year-Old Boy with GAII Administered with High-Dose Riboflavin: A Case Report
Inborn errors of metabolism can cause a number of morbidities and mortality in pediatric population. Glutaric aciduria II (GAII) or multiple acyl-CoA dehydrogenase deficiency (MADD) is an ultra-rare (i.e. <1:50 000) disorder of mitochondrial fatty acid oxidation (FAO) and amino acid metabolism. It is inherited in an autosomal recessive manner. Congenital deficiency of electron transfer flavoproteins and ETF dehydrogenase genes cause an illness that combines the features of impaired fatty acid oxidation and impaired oxidation of several aminoacides. Newborn screening (NBS) using tandem mass spectrometry (MS/MS) permits detection of neonates with glutaricaciduria-Type II.
We reported a five-year-old boy with muscle weakness of lower limb and inability to walk (myopathy), seizure due to hypoglycemia (as a result of prolonged fasting), hepatomegaly and rhabdomyolysis that treated with high dose riboflavin and he is well in follow up.
Early diagnosis of mild cases and treatment with high dose riboflavin may have better prognosis.
