Özet
Objectives: Glycogen storage disease type V is caused by the mutations in muscle glycogen phosphorylase gene. This is the first report which DL-3-hydroxybutyric acid was used in combination with modified Atkins diet for the treatment of a patient with glycogen storage disease type V and quadriceps femoris shear wave elastography was performed to evaluate the treatment efficacy. Case presentation: A 13-year-old girl was referred with fatigue and muscle cramps with exercise and there were no pathological findings in physical examination. Creatine kinase levels with 442 U/L. No phosphorylase enzyme activity was detected in muscle biopsy, a homozygous c.1A>G (p.M1V) pathogenic mutation was found in PYGM gene. She was started on DL-3-hydroxybutyric acid and modified Atkins diet at age 16. Her walking and stair climbing capacity increased, the need for rest during exercise decreased. The stiffness of the quadriceps femoris exhibited a reduction. Conclusions: DL-3-hydroxybutyric acid and modified Atkins diet may provide an alternative fuel and shear wave elastography may be useful in demonstrating treatment efficacy. More clinical and pre-clinical studies are obviously needed to reach more definite conclusions.
