Abstract
BACKGROUND
Isolated hemolysis or hemolytic anemia and 5-oxoprolinuria are 2 distinct medical conditions in the clinical spectrum associated with glutathione synthetase deficiency.
CLINICAL OBSERVATION
A 1-day-old female baby presented with anemia and respiratory distress. Her hemoglobin level was 9.5 g/dL and the total serum bilirubin level was 5.6 mg/dL. Metabolic acidosis was detected in her blood gas analysis. Metabolic acidosis recurred despite treatment and further investigation was required. Her 5-oxoproline level was 3815 mmol/mol creatinine in urine organic acid analysis, and a homozygous mutation [p.R125H (c.374G>A)] was found in the glutathione synthetase gene.
CONCLUSIONS
GSD has been observed in very few patients and is rarely considered in the differential diagnosis of hemolytic anemia in newborns.
