Aim To describe a spectrum of intracerebral large artery disease in Aicardi-Goutières syndrome (AGS) associated with mutations in the AGS5 gene SAMHD1. Method We used clinical and radiological description and molecular analysis. Results Five individuals (three males, two females) were identified as having biallelic mutations in SAMHD1 and a cerebral arteriopathy in association with peripheral vessel involvement resulting in chilblains and ischaemic ulceration. The cerebral vasculopathy was primarily occlusive in three patients (with terminal carotid occlusion and basal collaterals reminiscent of moyamoya syndrome) and aneurysmal in two. Three of the five patients experienced intracerebral haemorrhage, which was fatal in two individuals. Post-mortem examination of one patient suggested that the arteriopathy was inflammatory in origin. Interpretation Mutations in SAMHD1 are associated with a cerebral vasculopathy which is likely to have an inflammatory aetiology. A similar disease has not been observed in patients with mutations in AGS1 to AGS4, suggesting a particular role for SAMHD1 in vascular homeostasis. Our report raises important questions about the management of patients with mutations in SAMHD1. [ABSTRACT FROM AUTHOR]

The present controlled study aims to evaluate topiramate (TPM) effect on total cholesterol (TC), high-density lipoprotein (HDL), low-density lipoprotein, very low-density lipoprotein, apolipoproteins A1, B and lipoprotein (a). Seventy patients in evolving age suffering from various types of epilepsy, treated with TPM, (age range: 6 months–22 years) were evaluated before and after 12 months of treatment and compared with 110 sex- and age-matched subjects. At baseline, no significant difference was present between controls and children treated with TPM. After a year, the BMI did not show significant change in adults and remained into respective growth curve. No significant difference in lipids and lipoproteins neither between first and second evaluation nor between patients and controls was found. Some intra-group variation has been noticed: whilst controls maintained similar levels, the 70 patients on TPM monotherapy showed a slight decrease in TC, triglycerides and HDL. These fluctuations, however, occurred in the normal range so neither dietary nor pharmacological treatment of hyperlipidaemia after a year of TPM was necessary. [ABSTRACT FROM AUTHOR]

The aim of the present study was to assess serum lipid levels before and after treatment with oxcarbazepine (OXC) in children with epilepsy. We measured total cholesterol (TC), triglycerides (TGs) and high-density lipoprotein cholesterol (HDL-C) in 28 patients whereas only TC levels in 11 patients, during baseline period and at 3 months after the beginning of therapy with OXC. During baseline period, median values were: 4.38 mmol/l (IQR = 4.12–5.03) for TC levels, 1.72 mmol/l (IQR = 1.42–2.01) for HDL-C levels and 1.54 mmol/l (IQR = 1.29–1.96) for TGs levels. At 3 months, median values were: 4.38 mmol/l (4.10–4.95) for TC levels ( P < 0.05), 1.57 mmol/l (1.34–1.93) for HDL-C levels ( P < 0.005) and 1.8 mmol/l (1.23–2.34) for TGs levels ( P < 0.05). Median serum lipid levels remained in the normal range, despite an increasing-trend at 3 months of treatment with OXC. Further studies are necessary to confirm these results. [ABSTRACT FROM AUTHOR]

In this review, we trace the origins and follow the development of mitochondrial medicine from the premolecular era (1962-1988) based on clinical clues, muscle morphology, and biochemistry into the molecular era that started in 1988 and is still advancing at a brisk pace. We have tried to stress conceptual advances, such as endosymbiosis, uniparental inheritance, intergenomic signaling and its defects, and mitochondrial dynamics. We hope that this historical review also provides an update on mitochondrial medicine, although we fully realize that the speed of progress in this area makes any such endeavor akin to writing on water., ((c) 2010 Wiley-Liss, Inc.)
