Moya moya syndrome in a child with pyruvate kinase deficiency and combined prothrombotic factors
A 13-year-old Greek girl with pyruvate kinase deficiency and moya moya
angiographic pattern is reported. She also had raised serum lipoprotein
(a) concentration and was homozygous for the C677T mutation of the
methylenetetrahydrofolate reductase gene. She presented with neonatal
onset of anemia, hemolytic and aplastic crises, especially during
infections, stroke, and also progressive motor and mental deterioration.
A digital cranial angiography at 13 years revealed the typical
angiographic findings of moya moya angiopathy. This is likely the first
patient with pyruvate kinase deficiency and moya moya syndrome and also
the combination of elevated serum lipoprotein (a) concentration and the
C677T mutation of the methylenetetrahydrofolate reductase gene to be
reported. In patients with pyruvate kinase deficiency and moya moya
syndrome, a search for raised serum lipoprotein (a) concentrations and
the C677T mutation of the methylenetetrahydrofolate reductase gene
should be considered
Effect of sodium valproate monotherapy on serum uric acid concentrations in ambulatory epileptic children: A prospective long-term study
Purpose: Hyperuricemia has been shown to be related to cardiovascular
morbidity and mortality. There is controversial data about the effect of
sodium valproate (VPA) monotherapy on serum uric acid concentrations.
The purpose of this study was to investigate by a long-term, prospective
method, whether treatment with VPA monotherapy may alter serum uric acid
concentrations and liver function tests in ambulatory epileptic
children.
Material and methods: Serum uric acid concentrations were determined in
28 ambulatory epileptic children before and at 6, 12 and 24 months of
VPA monotherapy. Serum concentrations of biochemical markers of liver
and renal function, such as alanine aminotransferase (ALT), aspartate
aminotransferase (AST), lactate dehydrogenase (LDH),
gamma-glutamyltransferase (gamma-GT) and creatinine (Cr) were also
measured before and at 6, 12 and 24 months of VPA monotherapy. Serum VPA
concentrations remained within the therapeutic range (50-100 mg/L)
during the period of study.
Results: No statistically significant changes in serum Uric acid
concentrations were found at 6, 12 or 24 months of treatment. Serum ALT
concentrations were significantly increased at 6 and 12 months of
treatment, AST concentrations at 6 and 12 months of treatment and LDH
concentrations at 12 months of treatment.
Conclusions: VPA monotherapy does not have a significant effect on serum
uric acid concentrations in ambulatory epileptic children. Further
studies are needed to definitively address whether it would be useful
for physicians to routinely check for elevated serum uric acid levels in
children treated with VPA. (C) 2006 European Paediatric Neurology
