G6PD Deficiency and Priapism: Is There a Link Between the Two Entities?

Area of Science:

• Biochemistry
• Hematology
• Urology

Background:

• Glucose 6 phosphate dehydrogenase (G6PD) is a vital enzyme for cellular survival, particularly in red blood cells (RBCs).
• G6PD is the sole source of nicotinamide adenine dinucleotide phosphate (NADPH) in RBCs, essential for combating oxidative stress.
• G6PD deficiency is primarily known for causing hemolytic anemia due to impaired defense against reactive oxygen species.

Observation:

• This report details a rare case of priapism.
• Priapism is a prolonged erection unrelated to sexual stimulation.
• All other potential causes of priapism were systematically ruled out in this patient.

Findings:

• The presented case links G6PD deficiency to priapism as a rare complication.
• This association is uncommon and not widely documented in medical literature.
• The underlying mechanism connecting G6PD deficiency to priapism requires further investigation.

Implications:

• This case expands the known clinical spectrum of G6PD deficiency.
• Recognizing priapism as a potential G6PD deficiency complication is crucial for diagnosis.
• Further research is needed to elucidate the pathophysiology and guide clinical management.
