Lysosomes and mucopolysaccharidoses

Therapy 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...

Musculoskeletal manifestations of mucopolysaccharidoses.

The mucopolysaccharidoses (MPSs) are a heterogeneous group of inherited metabolic disorders caused by enzyme deficiencies that lead to progressive lysosomal storage of glycosaminoglycans. Musculoskeletal manifestations are common across all forms of MPS and are often apparent early in the disease course. Diagnostic delays occur frequently in these patients, especially those with more attenuated...

Diagnosis of the mucopolysaccharidoses.

The mucopolysaccharidoses (MPSs) often present a diagnostic challenge, particularly for patients who have more slowly progressive disease phenotypes, as early disease manifestations can be subtle or non-specific. However, certain types of bone and joint involvement should always prompt consideration of an MPS diagnosis, such as early joint involvement without classic inflammatory features or er...

Replacement therapy in the mucopolysaccharidoses.

Radiologic and neuroradiologic findings in the mucopolysaccharidoses.

The mucopolysaccharidoses (MPS) represent a group of inheritable, clinically heterogeneous lysosomal storage disorders, in which progressive accumulation of glycosaminoglycans (GAGs) can affect organs and tissues all over the body. The current paper discusses the skeletal X-ray and neuroimaging findings in MPS patients, and the imaging techniques that can be used for diagnosing and monitoring a...
