Newborn screening and diagnosis of mucopolysaccharidoses.
Mucopolysaccharidoses (MPS) are caused by deficiency of lysosomal enzyme activities needed to degrade glycosaminoglycans (GAGs), which are long unbranched polysaccharides consisting of repeating disaccharides. GAGs include: chondroitin sulfate (CS), dermatan sulfate (DS), heparan sulfate (HS), keratan sulfate (KS), and hyaluronan. Their catabolism may be blocked singly or in combination dependi...
متن کاملTherapy for the mucopolysaccharidoses.
Better understanding of disease pathophysiology, improved supportive care and availability of disease-specific treatments for some of the mucopolysaccharidosis (MPS) disorders have greatly improved the outlook for patients with MPS disorders. Optimal management of these multisystemic disorders involves a multidisciplinary team and regular, comprehensive follow-up. Enzyme replacement therapy (ER...
متن کاملDimethylmethylene blue-based spectrophotometry of glycosaminoglycans in untreated urine: a rapid screening procedure for mucopolysaccharidoses.
Glycosaminoglycans (GAGs) are measured in urine to screen for mucopolysaccharidoses. Other assay procedures are only qualitative (spot tests), can give false-negative results (spot tests, turbidity tests), or are relatively laborious (uronic acid-carbazole test). The present spectrophotometric procedure, based on the color reaction with dimethylmethylene blue (DMB), can be performed directly on...
متن کاملScreening for Chlamydia trachomatis among Infertile Women Using PCR Method
Background & objectives: Chlamydia trachomatis is a gram negative bacterium and chlamydia infection, as a curable infection, is one of the most common sexually transmitted diseases (STD). With regard to the essential role of chlamydia in infertility, the study of the prevalence of asymptomatic cases is precious. The aim of this study was to determine of the prevalence of chlamydia trachomatis...
متن کاملThe spot test is not a reliable screening procedure for mucopolysaccharidoses.
To check the reliability of the Ames MPS paper spot test, which is based on the Azure A dye, we sent a series of urine samples to three laboratories where the spot test is part of the metabolic screening for mucopolysaccharidoses. In these laboratories false-negative results ranged between 19% and 35% and false-positive results ranged between 12% and 29% of all samples submitted. In contrast, t...
