Adult metachromatic leukodystrophy: disorganized schizophrenia-like symptoms and postpartum depression in 2 sisters.

We describe the cases of 2 sisters with adult metachromatic leukodystrophy (MLD). Whereas one sister presented with disorganized schizophrenia-like symptoms as the initial manifestation of MLD, the other remained symptom free except for a 4-week period of postpartum depression. In both patients, there was some residual activity of leukocyte arylsulfatase A (1.7% and 5.5% of normal), and a marked increase in urinary sulfatides was present, as measured by tandem mass spectrometry. An arylsulfatase A pseudodeficiency was therefore excluded. The most common mutations of the adult phenotype, Ile-179-Ser and Pro-426-Leu, were not found. In the literature, only 1 case of adult MLD manifesting as disorganized schizophrenia-like symptoms has been described, whereas postpartum depression has been so far unknown as a presenting symptom of MLD.

Angiotensin-converting enzyme gene polymorphism as a cardiovascular risk factor in children.

A family history of cardiovascular disease predicts cardiovascular risk in the next generation, which is either the result of inherited traits or certain living habits in some families. The aim of our study was to evaluate both variables and particularly the role of one of the possible genetic risk factors - angiotensin-converting enzyme (ACE) gene polymorphism. History and anthropometric and biochemical parameters, ACE gene polymorphism and carotid wall thickness - intima media thickness (IMT) were studied in two groups of children: in children whose parents had a stroke before the age of 45 years and in children without a positive family history. The preliminary results of the present study failed to confirm our hypothesis that ACE gene polymorphism is a cardiovascular risk factor in children of parents with premature stroke.
