Title Diabetes Does Not Explain It All
Creator Skidd, Philip M; Joseph F. Rizzo III, M.D.; Eichler, Florian S; Cestari, Dean M
Subject Adult polyglucosan body disease; Glycogen branching enzyme 1; Optic atrophy
Presenting Symptom A 62 year-old male referred for a six month history of progressive, painless, vision loss.
History Systemic hypertension, type II diabetes mellitus, hypercholesteremia, anxiety and depression.
Clinical On our examination his, best corrected visual acuity was 20/40 OU, and he was able to identify 2/8 color plates OU. Pupils were normal without an RAPD. Humphrey visual fields showed a fairly congruous right homonymous hemianopsia. The optic nerves were pale with an enlarged cup-to-disc ratio of 0.7 OU. A brain MRI showed global atrophy of the cerebrum, cerebellum, brainstem, upper cervical cord, with extensive confluent periventricular and subcortical disease, without enhancement. On further questioning, he revealed a history of erectile dysfunction and bladder urgency dating back at least ten years. He then developed progressive difficulties with gait, and balance. He denied cognitive deterioration and attributed any slowing in his cognition to normal aging.
Neuroimaging MRI
Pathology Genetic testing for the glycogen branching enzyme 1 (GBE1) detected a heterozygous mutation, and a functional enzymatic activity assay confirmed dysfunction of glycogen branching enzyme 1.
Disease/Diagnosis Adult polyglucosan body disease (APBD)
Treatment Trihetanoin
