Sydenham's chorea and schizophrenia: a case report.

The following is a case report of a patient with Sydenham's chorea who
later developed schizophrenia. Autopsy examination of this patient
revealed mineral deposits in the basal ganglia. The deposition of
minerals, especially iron, within subcortical brain structures has
been associated with dopaminergic abnormalities, schizophreniform
symptoms, and abnormal movement disorders. The psychosis these
patients experience is sometimes resistant to treatment with
traditional neuroleptics. A CT or MRI scan may prove useful in
screening those patients with Sydenham's chorea that develop psychotic
symptoms.

A case of hereditary ceruloplasmin deficiency with iron deposition in the brain
associated with chorea, dementia, diabetes mellitus and retinal pigmentation:
administration of fresh-frozen human plasma.

We report a familial case of hereditary ceruloplasmin deficiency (HCD)
showing an A-G transition in intron 6 of the ceruloplasmin gene.
Clinical features consisted of chorea, cerebellar ataxia, dementia,
diabetes mellitus, retinal pigmentation and iron deposition in the
liver and brain without copper overload in those organs. The patient's
children and siblings had similar laboratory results, but did not show
any neurological abnormalities. She was medicated for diabetes
mellitus at 43 years of age, and neurological signs appeared when she
was 52 years old. The laboratory findings were anemia, low
concentrations of iron and copper in serum and of copper in urine.
Ceruloplasmin was not detected in the serum. The iron and copper
contents in the liver were 3,580 and 10 microg/g wet tissue,
respectively. MRI of the brain showed iron deposition in the basal
ganglia, dentate nucleus and thalamus. This case did not show any
abnormal increase in copper in the blood and urine following
CuSO(4)5H(2)O oral overloading test. Following the intravenous
administration of commercially available fresh-frozen human plasma
(FFP) containing ceruloplasmin, the serum iron content increased for
several hours due to ferroxidase activity of ceruloplasmin. In the
liver, the iron content decreased more with the combined intravenous
administration of FFP and deferoxamine than with FFP administration
alone. Her neurological symptoms improved following repetitive FFP
treatment.
