Five patients with glycogen storage disease type I (GSD-I) were evaluated for a bleeding diathesis and subsequently were given an infusion of 1-deamino-8-D-arginine vasopressin (DDAVP). Although platelet counts were normal or slightly elevated, the baseline template bleeding times were prolonged in four of the patients. Prothrombin times and activated partial thromboplastin times were normal, while ADP- and epinephrine-induced platelet aggregations were absent in the three patients tested. Ristocetin- and collagen-induced platelet aggregations were abnormal. Laurell and immunoradiometric determinations of the factor VIII-related antigen (vWf antigen) were decreased. Glyoxyl agarose gel electrophoresis of the patients' plasma revealed abnormal multimer patterns in four of the five patients. After the DDAVP infusion the platelet aggregation abnormalities persisted; however, the bleeding time and the von Willebrand antigen and activity corrected. We conclude that GSD-Ia patients may have a metabolically acquired form of von Willebrand's syndrome as well as an acquired intrinsic platelet defect, and that DDAVP may be useful in the management of bleeding in these patients.

Glycogen storage disease type IV (GSD-IV) is a rare autosomal recessive disease caused by deficient glycogen branching enzyme (GBE). We report a 15-month-old female patient with GSD-IV who exhibited an abdominal distension and failure to thrive for 9 months. The patient showed hepatosplenomegaly with massive ascites. The laboratory findings showed abnormal liver functions including prolongation of prothrombin time and partial thromboplastin time. The light microscopic and electron microscopic findings of the liver biopsy specimen were consistent with GSD-IV. Measurement of glycogen quantity in the red blood cells showed increased storage of glycogen in the patient and interestingly, in her mother. The GBE activity of the patient's red blood cells was undetectable. The patient's ascites, general condition, and laboratory findings have been improved with supportive treatment with diuretics and a low dose of prednisolone.
