OBJECTIVE The knowledge of the molecular basis of the Phenylketonuria (PKU, MIM# 261600) in different countries provides relevant information for undertaking specific and rational mutation detection strategies in each population and for the implementation of adequate dietary and cofactor treatment. There are no data available in Moroccan population. (More)
The study objective was to determine if Ramadan fasting was safe in patients with type 2 diabetes mellitus (T2D), based upon a determination of the effect of fasting on a broad range of physiological and clinical parameters, including markers of glycemic control and blood pressure. The study was carried out in Ramadan 1422 (December 2001-January 2002) at(More)
The J774.1 macrophage cell line was used as a tool to investigate the influence of selenium on macrophage function. In vitro selenium supplementation enhanced phagocytosis, degranulation by the release of beta-glucuronidase after N-formyl-methionyl-leucyl-phenylalanine (FMLP) or cytochalasin B, and the production of superoxide anion after phorbol myristate(More)
The oculo-cerebro-renal syndrome of Lowe is a rare X-linked disorder, caused by the inositol biphosphate 5-phosphatase deficiency, localized to the Golgi complex. Several mutations were reported in patient's OCRL gene leading to enzyme deficiency. We report a Moroccan case of OCRL syndrome of Lowe with a neo mutation in exon 10. The patient aged of 19(More)
BACKGROUND Familial hypercholesterolemia (FH) is an autosomal dominant disorder caused by mutations in the low-density lipoprotein receptor (LDLR), apolipoprotein B (APOB) and proprotein convertase subtilisin/kexin type 9 (PCSK9) genes. Until now, molecular data concerning FH in Morocco is still limited. To gain more information in this field and to assess(More)
BACKGROUND Congenital adrenal hyperplasia (CAH) is an autosomal recessive disease most often due to steroid 21-hydroxylase deficiency (21OHD). The incidence of the CYP21A2 gene mutations in 21OHD has been extensively studied in recent years. The p.Q318X mutation presents an ethnic-specific distribution with a higher prevalence (40%) in Tunisia. METHODS A(More)
Congenital nephrogenic diabetes insipidus is a rare, hereditary in nature, characterized by an inability of the kidney to concentrate urine, secondary to the manifold resistance to the action of vasopressin. X-linked forms of transmission (90%) are expressed in boys, from the neonatal period in general, by polyuria and polydipsia. Symptomatology in(More)
We report in this paper the case of female patient, hypertriglyceridemia associated with milky serum and hyperglycemia have been the alarm signal of a lupus-associated pancreatitis, the confirmation of this entity was done with elevated rate of serum lipase activity. It is about a 33 years age female. She has as unique antecedent a lupus diagnosed on(More)
A specific and sensitive method for the determination of unconjugated dehydroepiandrosterone in plasma is described. After extraction and purification of the extracts on a Celite column, the iodomethyldimethylsilyl ether derivative of dehydroepiandrosterone was isolated on an aluminium oxide column and assayed by gas chromatography with electron-capture(More)
