N2 - Glycosaminoglycans in urine from patients representing the major different mucopolysaccharidoses were separated and measured by use of a procedure that requires only 2 mL of urine. The compounds were resolved by two-dimensional electrophoresis on cellulose acetate plates and made visible by staining with Alcian Blue. They were identified by co-migration with standard glycosaminoglycans, by digestion with specific glycosidases, and by specific degradation with HNO 2. They were quantitated by comparing the absorbance of eluates of the stained spots to appropriate standard curves for each glycosaminoglycan. This study revealed additional findings. About half of the patients excreted small amounts of heparin. Further, the keratan sulfate in samples from ...

Mucopolysaccharidoses (MPS) are the group of lysosomal storage disorders caused by deficiencies of enzymes involved in the stepwise degradation of glycosaminoglycans. To identify brain pathology common for neurological MPS, we conducted a comprehensive analysis of brain cortex tissues from post-mortem autopsy materials of eight patients affected with MPS I, II, IIIA, IIIC, and IIID, and age-matched controls. Frozen brain tissues were analyzed for the abundance of glycosaminoglycans (heparan, dermatan, and keratan sulfates) by LC-MS/MS, glycosphingolipids by normal phase HPLC, and presence of inflammatory cytokines interleukin-6 (IL-6) and tumor necrosis factor superfamily member 10 (TNFSF10) by Western blotting. Fixed tissues were stained for the markers for microgliosis, astrogliosis, misfolded proteins, impaired autophagy, and GM2ganglioside. Our results demonstrate that increase of heparan sulfate, decrease of keratan sulfate, and storage of simple  monosialogangliosides 2 and 3 (GM2 and GM3) as

Mucopolysaccharidoses (MPS) are rare, inherited lysosomal storage disorders characterized by progressive multiorgan involvement. Previous studies on incidence and prevalence of MPS mainly focused on countries other than the United States (US), showing considerable variation by country. This study aimed to identify MPS incidence and prevalence in the US at a national and state level to guide clinicians and policy makers. This retrospective study examined all diagnosed cases of MPS from 1995 to 2015 in the US using the National MPS Society database records. Data included year of birth, patient geographic location, and MPS variant type. US population information was obtained from the National Center for Health Statistics. The incidence and prevalence rates were calculated for each disease. Incidence rates were calculated for each state. We obtained information from 789 MPS patients during a 20-year period. Incidence of MPS in the US was found to be 0.98 per 100,000 live births. Prevalence was found to be 2

The resulting intracellular accumulation of GAGs leads to widespread tissue and organ dysfunction. In addition to somatic signs and symptoms, patients with MPS can present with neurological manifestations such as cognitive decline, behavioral problems (e.g. hyperactivity and aggressiveness), sleep disturbances, and/or epilepsy. These are associated with significant abnormalities of the central nervous system (CNS), including white and gray matter lesions, brain atrophy, ventriculomegaly, and spinal cord compression. In order to effectively manage ...

Mucopolysaccharidoses are a group of metabolic disorders characterized by the accumulation of GAGs (glycosaminoglycans, or mucopolysaccharides) due to the impaired functions of lysosomal enzymes. It is the mucopolysaccharides which help in building bones, cartilage, skin, tendons, corneas, and the fluid responsible for lubricating joints.

Mucopolysaccharides are long molecular chains of sugar. They are used by the body in the building of connective tissues. They must also be broken down and reused by the body. Children with MPS are unable to produce one of the enzymes essential to this task. Mucopolysaccharide diseases (or Mucopolysaccharidosis or MPS) are genetic diseases caused by recessive genes. There are seven Mucopolysaccharide (MPS) disorders. They are referred to as MPS I-VII but many of them go by the name of the doctor who first described the condition as well. Hunter syndrome, Hurler syndrome, Scheie syndrome, Sanfilippo syndrome, Maroteaux-Lamy syndrome, and Morquio disease are all Mucopolysaccharide diseases.

MPS III, like the other MPS conditions, was initially diagnosed by the individual having certain physical signs and symptoms. It was later discovered that the physical symptoms associated with Sanfilippo syndrome could be caused by a deficiency in one of four enzymes. MPS III is in the early 2000s subdivided into four groups, labeled A through D, based on the specific enzyme that is deficient. All four of these enzymes are involved in breaking down the same GAG, heparan sulfate. Heparan sulfate is mainly found in the central nervous system and accumulates in the brain when it cannot be broken down because one of those four enzymes is deficient or missing. MPS III is a variable condition, with symptoms beginning to appear between two and six years of age. Because of the accumulation of heparan sulfate in the central nervous system (CNS), the CNS is severely affected. In MPS III, signs that the CNS is degenerating usually become evident between six and ten years of age. Many children with MPS III ...

Presented by the National MPS Society and the University of Minnesota Division of Clinical Behavioral Neuroscience, designed for doctoral-level psychologists, trainees, and psychometrists seeing MPS patients in clinical trials, this comprehensive course will provide a robust understanding and increased site readiness in response to the growing number of MPS trials.

The MPS share many clinical features, although in variable degrees. These include a chronic and progressive course, multisystem involvement, organomegaly, dysostosis multiplex, and abnormal facies. Hearing, vision, airway, cardiovascular function, and joint mobility may be affected. Profound mental retardation is characteristic of MPS IH (Hurler syndrome), the severe form of MPS II (Hunter syndrome), and all subtypes of the MPS III (Sanfilippo syndrome), but normal intellect may be retained in other MPS. The bony lesions of MPS IV (Morquio syndrome) are specific to that disorder. There is clinical similarity between different enzyme deficiencies, and, conversely, a wide spectrum of clinical severity within any one enzyme deficiency. Supportive management-with particular attention to respiratory and cardiovascular complications, loss of hearing and vision, communicating hydrocephalus, and spinal cord compression-can greatly improve the quality of life for patients and their families.. ...

Approximately 85% of individuals with Mucopolysaccharidosis (MPS) type I, II, or VI report weekly pain and 50-60% have significant limitations in their activities of daily living due to MPS related musculoskeletal disease despite treatment with enzyme replacement therapy (ERT). Thus there is a critical need to identify additional therapies to alleviate the burden of musculoskeletal disease in order to improve the health and quality of life of individuals with MPS. However, disease progression needs to be quantified to be able to determine efficacy of new therapies. This study is a multi-institutional, 5-year, longitudinal study of musculoskeletal disease in MPS. The objective is to quantitatively describe the progression of skeletal disease and identify biomarkers that either predict disease severity or could be used as therapeutic targets in individuals with MPS I, II, and VI. A database of standardized measurements of musculoskeletal disease in MPS will allow the field to efficiently move ...

Lysosomes are cells recycling and waste disposal system. It contains a battery of enzymes (acid hydrolases) that degrade a wide variety of macromolecules and cellular debris into reusable forms. In so doing lysosomes play a vital role in maintaining cellular homeostasis. The broad goal of our research is to understand the role of this fascinating organelle in human health and diseases. We use various methods ranging from molecular biology, cell biology, protein biochemistry to genomic and proteomic tools to address our research problems. Current research in our laboratory is focused on two major areas: 1. To investigate the pathogenesis of mucopolysaccharidoses, a group of genetic disorders caused by deficiency of one of the eleven lysosomal enzymes required for stepwise degradation of glycosaminoglycans (GAGs). Widespread lysosomal accumulation of undegraded or partially degraded GAGs results in cellular and multiple organ dysfunctions leading to premature death in most cases. The genetic ...

In Sanfilippo syndrome, mucopolysaccharides are stored primar ily in the nerve system. There are four different enzyme deficiencies that cause Sanfilippo syndrome and hence the syndrome is classified as type A, B, C or D.. Type A is considered the most severe form, type B consists of both a milder and more severe form, and type C is considered to lie between types A and B in severity. Type D is very uncommon. The children are born healthy and develop normally up to between 2 and 6 years of age, after which developmental disorders, such as delayed speech and language development, and autistic traits appear.. Extreme hyperactivity is common. Thereafter, a progressive deter ioration occurs. Gradually mental retardation becomes apparent. In the next phase, balance worsens, as well as the ability to walk and mental capabilities. Epilepsy may occur. Skeletal deformities and stiffness of the joints may occur. Respiratory tract infections are common. Ear infections may cause hear ing impairments. ...

Lysosomal storage disorders (LSDs) is a term used to describe a group of diseases caused by a defect in lysosome enzymes. Lysosomes act as the recycling center of each cell, breaking down unwanted materials into simple waste products. The lack of certain lysosomal enzymes causes a buildup of waste products in many cells of the body.. The clinical symptoms depend on the cells and tissues that use the deficient enzyme and if any working amount of enzyme is present. The types of LSDs are named for the substance that builds up in the cells.. Mucopolysaccharidoses (MPS) disorders are the most common (1 in 25,000 births) of the LSDs. There are more than 40 known types, including those known by the common names listed below:. ...

In the present study, we examined BBB integrity in various brain structures of post-mortem tissues from two patients, one with MPS III A and one with MPS III D. We determined not only substantial structural BBB impairment in both cases, but also functional CNS barrier damage, which may have implications for disease pathogenesis. These new findings should be considered as a basis for determining the role of vascular dysfunction in MPS III and, specifically, are supportive of targeting the BBB for treatment development..

The MPS Family of Diseases. There is a continuous process in the body of replacing used materials and breaking them down for disposal. Children born with Mucopolysaccharide or MPS are unable to produce one of the enzymes essential for this process. Used materials cannot be broken down and remain stored in the cells of the body.. Babies born with one of the nine forms of MPS may show no sign of the disease, but as more and more cells become damaged by the storage of used material, symptoms begin to appear. Sadly the MPS family of disease is progressive which lead to an increase in symptoms and the problems they create as the years go by.. Sanfilippo Syndrome. Sanfilippo Syndrome is one of nine mucopolysaccharide diseases. Also known as MPS lll, it takes its name from Dr. Sanfilippo who was one of the doctors who first described the condition in 1963. MPS III is subdivided into 4 similar subtypes. Sophie suffers from the particular subtype MPS III B.. How does the disease progress?. Children begin ...

HSGAG and CSGAG modified proteoglycans first begin with a consensus Ser-Gly/Ala-X-Gly motif in the core protein. Construction of a tetrasaccharide linker that consists of -GlcAβ1-3Galβ1-3Galβ1-4Xylβ1-O-(Ser)-, where xylosyltransferase, β4-galactosyl transferase (GalTI),β3-galactosyl transferase (GalT-II), and β3-GlcA transferase (GlcAT-I) transfer the four monosaccharides, begins synthesis of the GAG modified protein. The first modification of the tetrasaccharide linker determines whether the HSGAGs or CSGAGs will be added. Addition of a GlcNAc promotes the addition of HSGAGs while addition of GalNAc to the tetrasaccharide linker promotes CSGAG development.[5] GlcNAcT-I transfers GlcNAc to the tetrasaccahride linker, which is distinct from glycosyltransferase GlcNAcT-II, the enzyme that is utilized to build HSGAGs. EXTL2 and EXTL3, two genes in the EXT tumor suppressor family, have been shown to have GlcNAcT-I activity. Conversely, GalNAc is transferred to the linker by the enzyme GalNAcT ...

To help you understand more on rare diseases, here are some Q&A about RARE DISEASES. What is a rare disease?. Briefly speaking, rare diseases suggest diseases with low prevalence. Well known rare diseases include Phenylketonuria, Thalassemia, Osteogenesis Imperfecta, Mucopolysaccharidoses, Spinal Muscular Atrophy and so on. The number of patients may vary from one disease to another, which means some diseases may have bigger population over the others. Moreover, there have been only several cases of certain rare diseases in the world and those are hardly understood.. How do rare diseases occur?. Most rare diseases are result of genetic defects, and are often described as congenital diseases, meaning they are present at birth. However, some rare diseases have infantile and late onset and therefore, we do not think they should be classified as congenital condition. Genetic defects are sometimes caused by sporadic mutation or by inheritance. However, causes of certain rare diseases still remain ...

Formal assessment of cognitive functions in patients with MPS III poses several major challenges. Hyperactive behavior, anxiety and aggressive behavior are a predominant symptom in MPS III [1, 21]. Concurrent concentration problems [1], present in the majority of patients with MPS III, further complicate testing and assignments requiring longer instructions proved to be difficult for most patients. A test such as the BSID-II, which consists of many separate short tasks, was found to be the most suitable for these easily distracted patients. The more recently developed BSID-III appears to be even more suitable for testing this group of patients a s it consists of five distinct scales of development (Cognitive, Language, Motor, Social Emotional and Adaptive Behavior Scale), while the BSID-II consists of three scales (Mental, Motor and Behavior Scales). However, this test was not validated in Dutch at the time of this study.. Twenty-three percent of the tested patients showed a significant ...

Human beta-glucuronidase deficiency mucopolysaccharidosis: identification of cross-reactive antigen in cultured fibroblasts of deficient patients by enzyme immu

Hunter syndrome, or mucopolysaccharidosis type II (MPS II), is a member of a group of inherited metabolic disorders collectively termed mucopolysaccharidoses (MPSs). The MPSs are caused by a deficiency of lysosomal enzymes required for the degradation of mucopolysaccharides or glycosaminoglycans (GAGs).

The dimethylmethylene blue assay for sulphated glycosaminoglycans has found wide acceptance as a quick and simple method of measuring the sulphated glycosaminoglycan content of tissues and fluids. The available assay methods have lacked specificity for sulphated glycosaminoglycans in the presence of other polyanions, however, and have not discriminated between the different sulphated glycosaminoglycans. We now describe a modified form of the dimethylmethylene blue assay that has improved specificity for sulphated glycos-aminoglycans, and we show that in conjunction with specific polysaccharidases, the dimethylmethylene blue assay can be used to quantitate individual sulphated glycosaminoglycans ...

Mucopolysaccharidoses (MPS) are rare genetic diseases caused by the deficiency of one of the lysosomal enzymes involved in the glycosaminoglycan (GAG) breakdown pathway. This metabolic block leads to the accumulation of GAG in various organs and tissues of the affected patients, resulting in a multisystemic clinical picture, sometimes including cognitive impairment. Until the beginning of the XXI century, treatment was mainly supportive. Bone marrow transplantation improved the natural course of the disease in some types of MPS, but the morbidity and mortality restricted its use to selected cases. The identification of the genes involved, the new molecular biology tools and the availability of animal models made it possible to develop specific enzyme replacement therapies (ERT) for these diseases. At present, a great number of Brazilian medical centers from all regions of the country have experience with ERT for MPS I, II, and VI, acquired not only through patient treatment but also in clinical ...

The concept of enzyme replacement therapy for lysosomal storage diseases was enunciated by de Duve in 1964. However, much cell biology had to be learned before lysosomal enzymes could be developed into pharmaceuticals. A model system, consisting of cultured skin fibroblasts from patients with mucopolysaccharidoses (MPS), showed that their defective glycosaminoglycan catabolism could be corrected by factors derived from cells of a different genotype. The corrective factors were identified as lysosomal enzymes with a special feature, or recognition signal, that would permit efficient uptake. As the recognition signal was absent from a number of lysosomal enzymes secreted by fibroblasts from patients with I-cell disease (a monogenic disorder), it was postulated to be a post-translational modification of the lysosomal enzymes. It was subsequently shown to be a carbohydrate and identified as mannose-6-phosphate (M6P), which was recognized by ubiquitous M6P receptors. A second model system was the clearance,

OBJECTIVES. Glycosaminoglycans (GAGs) are mucopolysaccharides (heparan, dermatan and chondroitin sulphates and hyaluronic acid), which can be found in different tissues of the body. In urinary tract, GAGs allow the formation of a layer of water/urine in the surface of the mucosa, protecting and also facilitating the elimination of bacteria during micturition. In women and cats, alteration of GAGs layer as well as reduction of urinary excretion of GAGs is mentioned in interstitial cystitis (IC). In dogs, low concentrations of urinary GAGs seem to be associated with recurrence of urinary infections and urolithiasis. Disorders of GAGs degradation and presence of large amount in urine can be observed in mucopolysaccharidosis. Most of GAGs laboratorial colorimetric methods reported develop in acid pH solution with DMB (colorant), but in this condition, DMB can also react with other urinary proteins. Jong (1992) mentioned a modified method, in which DMB reacts only with GAGs, forming a steady complex, ...
