[Glucose-6-phosphate dehydrogenase deficiency in children: a case report]
Insights
Glucose-6-phosphate dehydrogenase (G6PD) deficiency, the most common red blood cell enzyme disorder, can cause hemolytic crisis after fava bean ingestion. This case highlights the varied clinical presentations of G6PD deficiency, emphasizing its importance in diagnosing hemolytic anemia.
Area of Science:
- Hematology
- Genetics
- Pediatrics
Background:
- Glucose-6-phosphate dehydrogenase (G6PD) deficiency is the most prevalent red blood cell enzyme disorder globally.
- Reduced G6PD activity elevates red blood cell susceptibility to oxidative stress, triggered by factors like fava beans or certain medications.
- Clinical manifestations range from acute hemolysis and chronic hemolysis to neonatal hyperbilirubinemia and asymptomatic cases.
Observation:
- A 2-year-old boy experienced a severe hemolytic crisis following fava bean consumption.
- The child had a history of unexplained neonatal jaundice and required red blood cell transfusion due to anemia.
- No family history of hemolytic anemia or parental consanguinity was reported.
Findings:
- Qualitative G6PD testing confirmed enzyme deficiency in the patient.
- The clinical presentation, triggered by favism, led to acute hemolytic anemia.
- The case underscores the diagnostic challenge posed by G6PD deficiency's variable clinical spectrum.
Implications:
- G6PD deficiency diagnosis is crucial for managing hemolytic anemia across all age groups.
- Awareness of G6PD deficiency's diverse presentations is essential for timely and accurate diagnosis.
- Prompt identification and avoidance of triggers like fava beans can prevent severe hemolytic episodes.
Introduction:
Glucose-6-phosphate dehydrogenase deficiency (G6PD deficiency) is the most common red blood cell (RBC) enzyme disorder. The decrease as well as the absence of the enzyme increase RBC vulnerability to oxidative stress caused by exposure to certain medications or intake of fava beans. Among the most common clinical manifestations of this condition, acute hemolysis, chronic hemolysis, neonatal hyperbilirubinemia, and an asymptomatic form are observed.
Objective:
To analyze the case of a child who presented hemolytic crisis due to favism.
Case Report:
A 2 year and 7 month old boy with a history of hyperbilirubinemia during the newborn period with no apparent cause, no family history of hemolytic anemia or parental consanguinity. He presented a prolonged neonatal jaundice and severe anemia requiring RBC transfusion. An intake of fava beans 48 h prior to onset of symptoms was reported. G6PD qualitative determination was compatible with this enzyme deficiency.
Conclusion:
G6PD deficiency can be highly variable in its clinical presentation, so it is necessary to keep it in mind during the diagnosis of hemolytic anemia at any age.

Glucose Transporters
Facilitated diffusion-glucose transporters (GLUTs) are encoded by the solute-linked carrier (SLC) family 2, subfamily A gene family, or SLC2A. The 14 GLUT protein members are distributed into three classes:
Energy-requiring Steps of Glycolysis
Glycolysis: Preparatory Phase
Pharmacokinetics in Pediatric Patients: Drug Metabolism
Glucose Homeostasis: Regulation of Blood Glucose
During fasting, when blood glucose levels are low, the pancreas secretes glucagon. it...
