Vimizim® was licensed as an ERT in 2014 in the EU and approved for use in MPS IVA in the UK in 2015. The treatment has led to overall less physical deterioration leading to reduced disability and some people benefiting from increased energy levels
ERT is currently available for many of the MPS diseases MPS I, MPS II, MPS IVA, MPS VI and MPS VII and Fabry. Hematopoietic Stem Cell Transplantation (HSCT) There are a number of possible sources of blood stem cells, these include the bone marrow, peripheral blood and umbilical cord blood Evaluation and management of individuals with MPS IVA are best undertaken by multiple specialists, coordinated by a physician specializing in the care of persons with complex medical problems. Physiatrists, physical therapists, and occupational therapists help optimize mobility and autonomy
Enzyme replacement therapy (ERT) is approved in the United States, European Union, and several other countries for patients with MPS I, MPS II, MPS IVA, MPS VI, and MPS VII (table 1) [ 1 ]. Indications vary across the MPS, but generally ERT is used in patients with moderate-to-severe disease or clinical complications IVA patients treated with HSCT, and HSCT for MPS IVA have demonstrated the improvement of pulmonary function, the activity of daily living, bone mineral density, cardiovascular involvement, and laxity of joints, and the reduction of the number of the surgical interventions [22-25] Vimizim is a type of enzyme replacement therapy (ERT). It was approved by the Food and Drug Administration (FDA) for the treatment of mucopolysaccharidosis (MPS) IVA. The FDA found Vimizim both safe and effective in treating people over 5 years of age with this disorder. While ERT is a safe therapy Mucopolysaccharidosis type IVA (MPS IVA, or Morquio syndrome type A) is an inherited metabolic lysosomal disease caused by the deficiency of the N-acetylglucosamine-6-sulfate sulfatase enzyme. The deficiency of this enzyme accumulates the specific glycosaminoglycans (GAG), keratan sulfate, and chondroitin-6-sulfate mainly in bone, cartilage, and its extracellular matrix Treatment guidelines for rare diseases are often scarce and difficult to find. Despite the lack of uniformity, general guidelines for orphan disease management are critical for fair and effective patient care, particularly when preemptive treatment leads to better patient outcomes, as is the case with mucopolysaccharidoses (MPS) (see Fig. 1 for MPS management strategy)
