Which gycogen storage disease is it (Type 1: Von Gierke, type 2: Pompe, type 3 Cori, or type 5: McArdle)
5-month-old girl presented with shortness of breath
and progressive muscle weakness 1 month before hospitalization.
On physical examination, she was extremely
floppy, had mild congestion of the pharyngeal wall, macroglossia,
coarse breath sounds with rhonchi over both
lung fields, regular heart beat with apical systolic murmur,
hepatomegaly, and grade 4 muscle power of the extremities.
The liver, heart, and muscle enzyme levels were
elevated: SGOT, 288 U/L; SGPT, 194 U/L; creatine kinase
(CK), 998 U/L (CK-MB, 72 U/L); and lactic dehydrogenase
(LDH), 762 U/L (LDH1:LDH2, 1.65). The specific
enzyme assay for acid maltase was not performed. Results
of other laboratory studies were normal. The chest X-ray
film showed cardiomegaly with infiltration of both upper
lung fields. Electrocardiography showed a diffuse enlarged
QRS complex, short PR interval, and left ventricular hypertrophy.
Echocardiography displayed hypertrophy of
the ventricular septum and walls, poor myocardial contractility,
and mild mitral regurgitation
