Our goal in using dual induction therapy is to bring the kidney transplant recipient closer (through more effectively timed lymphodepletion) to an optimally immunosuppressed state. Here, we report long-term results of a prospective randomized trial comparing (Group I,N=100) rATG/Dac (3 rATG, 2 Dac doses) vs. (Group II,N=100) rATG/Alemtuzumab(C1H) (1 dose each), using reduced tacrolimus dosing, EC-MPS, and early corticosteroid withdrawal. Lower EC-MPS dosing was targeted in Group II to avoid severe leukopenia...

OBJECTIVES: Optimal procedures for adjuvant treatment and post-surgical surveillance of resected non-small-cell lung cancer remain under discussion. Pathological features are the main determinant of follow-up therapy but have limited ability to identify patients at risk of recurrence. Increasingly, molecular markers are incorporated into clinical decision-making, including measures of tumor growth. The CCP score is a quantitative, molecular measure of proliferation derived from the RNA expression of 31 cell cycle genes and a component of the molecular prognostic score (mPS)...

Mucopolysaccharidosis (MPS) and Mucolipidosis (ML) share common phenotypes (coarse facial features, organomegaly, dysostosis multiplex) despite having different molecular basis. Thus, they pose great diagnostic challenge to treating clinicians. Differentiating between the two conditions requires a battery of tests from screening to molecular diagnosis. Besides discussing differential diagnosis of MPS like features with negative urinary Glycosaminoglycans (GAG), the authors also discuss the utility of p-nitrocatechol sulphate based chemical test as an important screening tool, besides establishing molecular basis in index case...

BACKGROUND: Many rare diseases of childhood are life-threatening and chronically debilitating, so living with a rare disease is an on-going challenge for patients and their families. MPS is one of a range of rare inherited metabolic disorders (IMDs) that come under category 3 of life-limiting conditions, where there is no curative treatment available at present. Although the study of rare diseases is increasingly novel, and of clinical importance to the population, the lack of empirical data in the field to support policy and strategy development is a compelling argument for further research to be sought...

BACKGROUND: Mucopolysaccharidoses (MPS) are a group of inborn errors of metabolism that are progressive and usually result in irreversible skeletal, visceral, and/or brain damage, highlighting a need for early diagnosis. METHODS: This pilot study analyzed 2862 dried blood spots (DBS) from newborns and 14 DBS from newborn patients with MPS (MPS I, n = 7; MPS II, n = 2; MPS III, n = 5). Disaccharides were produced from polymer GAGs by digestion with chondroitinase B, heparitinase, and keratanase II...

Mucolipidosis II (Inclusion cell or I-cell disease) is an autosomal recessive lysosomal storage disorder clinically comparable to the mucopolysaccharidoses (MPS), characterized by progressive respiratory and neurologic deterioration. Sleep problems, especially obstructive sleep apnea (OSA) and disrupted sleep architecture, are observed in other lysosomal storage diseases but have not been described in mucolipidosis II. We report the progression of polysomnographic abnormalities in a child with mucolipidosis II, demonstrated by worsening sleep-related hypoventilation, OSA, and sleep state fragmentation despite advancing PAP therapy...

Mucopolysaccharidosis (MPS) is an inherited metabolic disease and a member of the group of lysosomal storage disorders. Its hallmark is a deficiency of lysosomal enzymes involved in the degradation of mucopolysaccharides, also known as glycosaminoglycans (GAGs). The products of GAG degradation accumulate within lysosomes and in the extracellular space, thereby interfering with the degradation of other macromolecules. This process leads to chronic degeneration of cells, which in turn affects multiple organs and systems...

Current treatment options for MPS I have limited effects on some organs, including the skeletal system. In MPS animal models pentosan polysulphate (PPS) reduces the concentrations of glycosaminoglycans (GAGs) in tissues and body fluids and improves cartilaginous and osseous pathologies. The goals of this study were to investigate primarily the safety and secondary the clinical effects, concerning mobility and pain, of PPS treatment in MPS I patients. Four MPS I-Hurler-Scheie/-Scheie patients aged 35.6 ± 6...

Mucopolysaccharidoses (MPSs) are a group of disorders resulting from primary defects in lysosomal enzymes involved in the degradation of glycosaminoglycans (GAGs). Depending on the specific enzyme defect, the catabolism of one or more GAGs is blocked leading to accumulation in tissues and biological fluids. GAG measurements are important for high-risk screening, diagnosis, monitoring treatment efficacy, and patient follow up. The dimethylmethylene blue (DMB) spectrophotometric method commonly used in most biochemical genetics laboratories relies on a non-specific total GAG analysis which has led to false positive results, and even false negative results (mainly for MPS III and IV patients)...

We investigated the efficacy of allogeneic hematopoietic stem cell transplantation (alloHSCT) in pediatric patients with mucopolysaccharidosis (MPS). A retrospective analysis of transplantation data from 34 cases of MPS from the China Children Transplant Group, treated between December 2004 and September 2015, was conducted. Among the 34 cases, 12 cases were type I, 12 were type II, 4 were type IV, 4 were type VI, and 2 were of an unknown type. The median age at transplantation was 3.75 years (range, 1 to 7 years); the median follow-up time was 14 months (range, 2 to 119 months)...

4'-Ethynyl-2-fluoro-2'-deoxyadenosine (EFdA) is the most potent nucleoside analog inhibitor of HIV reverse transcriptase (RT). It retains a 3'-OH yet acts as a chain-terminating agent by diminishing translocation from the pretranslocation nucleotide-binding site (N site) to the posttranslocation primer-binding site (P site). Also, facile misincorporation of EFdA-monophosphate (MP) results in difficult-to-extend mismatched primers. To understand the high potency and unusual inhibition mechanism of EFdA, we solved RT crystal structures (resolutions from 2...

Keratan sulfate (KS) is commonly elevated in urine samples from patients with mucopolysaccharidosis type IVA (MPS IVA) and is considered pathognomonic for the condition. Recently, a new method has been described by Martell et al. to detect and measure urinary KS utilizing LC-MS/MS. As a part of the validation of this method in our laboratory, we studied the sensitivity and specificity of elevated urine KS levels using 25 samples from 15 MPS IVA patients, and 138 samples from 102 patients with other lysosomal storage disorders, including MPS I (n = 9), MPS II (n = 13), MPS III (n = 23), MPS VI (n = 7), beta-galactosidase deficiency (n = 7), mucolipidosis (ML) type II, II/III and III (n = 51), alpha-mannosidosis (n = 11), fucosidosis (n = 4), sialidosis (n = 5), Pompe disease (n = 3), aspartylglucosaminuria (n = 4), and galactosialidosis (n = 1)...

Several different lysosomal storage diseases, mainly mucopolysaccharidosis (MPS) type I, II, and VI, are complicated by severe obstruction of the upper airways, tracheobronchial malacia, and/or stenosis of the lower airways. Although enzyme replacement therapies (ERTs) are available, the impact of these on tracheobronchial alterations has not been reported. By extending the life expectancy of MPS patients with ERTs, airway problems may become more prevalent at advanced ages. These airway abnormalities can result in severe, potentially fatal, difficulties during anesthetic procedures...

Myofascial pain syndrome (MPS) is a leading cause of chronic musculoskeletal pain. However, its neurobiological mechanisms are not entirely elucidated. Given the complex interaction between the networks involved in pain process, our approach, to providing insights into the neural mechanisms of pain, was to investigate the relationship between neurophysiological, neurochemical and clinical outcomes such as corticospinal excitability. Recent evidence has demonstrated that three neural systems are affected in chronic pain: (i) motor corticospinal system; (ii) internal descending pain modulation system; and (iii) the system regulating neuroplasticity...

BACKGROUND: Amniotic fluid glycosaminoglycan estimation is a useful marker in fetuses affected with mucopolysaccharidoses (MPS). Although known for long, it is not widely used in the prenatal diagnosis. With the availability of more reliable analytical testing and knowledge of normal levels at specific gestations, amniotic fluid glycosaminoglycan at 16-22weeks of gestation can be a useful biomarker in the prenatal diagnosis of MPS. METHODS: Forty-one women with normal pregnancies were tested for glycosaminoglycan levels in the amniotic fluid and 8 pregnancies with known family history of MPS were tested by sulphated glycosaminoglycan assay...

Lysosomal Storage Disorders (LSDs) are a group of metabolic syndromes, each one due to the deficit of one lysosomal enzyme. Many LSDs affect most of the organ systems and overall about 75% of the patients present neurological impairment. Enzyme Replacement Therapy, although determining some systemic clinical improvements, is ineffective on the CNS disease, due to enzymes' inability to cross the blood-brain barrier (BBB). With the aim to deliver the therapeutic enzymes across the BBB, we here assayed biodegradable and biocompatible PLGA-nanoparticles (NPs) in two murine models for LSDs, Mucopolysaccharidosis type I and II (MPS I and MPS II)...

Maximizing anabolic responses to feeding and exercise is crucial for muscle maintenance and adaptation to exercise training. We hypothesized that enriching a protein drink with leucine would improve anabolic responses to resistance exercise (RE: 6 × 8 knee-extension repetitions at 75% of 1-RM) in both young and older adults. Groups (n = 9) of young (24 ± 6 y, BMI 23 ± 2 kg m(-2)) and older men (70 ± 5 y, BMI 25 ± 2 kg m(-2)) were randomized to either: (i) RE followed by Slim-Fast Optima (SFO 10 g PRO; 24 g CHO) with 4...

With the introduction and discharge of thousands of new micropollutants (MPs) every year, traditional water and wastewater treatment plants may be incapable of tackling them all. With their low concentrations and diversity in nature, MP removal encounters numerous challenges. Although some MPs are effectively eliminated via conventional treatment methods, most of them can easily escape and are retained in the discharged effluent. Therefore, advanced methods such as (i) adsorption, (ii) oxidation and advanced oxidation processes (O3 and O3-based advanced oxidation processes, UV/H2O2), (iii) membrane processes, and (iv) membrane bioreactors, become an inevitable approach...
