Treatments for Mucopolysaccharidosis IVA (MPS IVA, also called Morquio syndrome type A) by enzyme replacement therapy (ERT) and hematopoietic stem cell transplantation (HSCT) are limited in efficacy depending on the age of initiation and clinical phenotype. Thus, this study aims to assess the effects of treatments on MPS IVA patients compared to untreated MPS IVA patients and an age-matched control group.

When the COVID-19 pandemic halted in-person instruction, educators, therapists, and parents faced unprecedented challenges as they sought to maintain the delivery of educational and therapeutic services. Without any kind of model, new methods of delivering special education and therapeutic services arose out of necessity: Educators and therapists faced the burden of learning in the moment. The abrupt transition to distance delivery presented a unique challenge for children with neurodegenerative conditions who require consistent and intensive instruction and treatment to maintain their fragile skills. This brief is designed for educators and therapists who play a critical role in protecting the neurocognitive function and quality of life of children with neurodegenerative conditions.

The current outbreak of the novel severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), causing coronavirus disease 2019 (COVID-19), has become a worldwide pandemic with high morbidity and mortality in individuals with chronic disorders.1 The pandemic introduced many unanticipated challenges for patients with chronic and rare diseases, such as Gaucher disease (GD).2 GD is the most common inborn error of metabolism, caused by biallelic glucosylceramidase beta (GBA) variants and affecting the recycling of cellular glycolipids; GD manifests as hepatosplenomegaly, thrombocytopenia, anaemia and bone disease.3

Scheduled enzyme replacement therapy (ERT) during COVID-19 has often been disrupted. This article considers the possibility of adverse outcomes caused by the disruption in the treatment of patients with lysosomal storage disorders. The full text of the article is available here.
The Sanfilippo Children’s Foundation is now accepting Expressions of Interest for their 2021 Grants Round.
– Wednesday 24 February: Grant round opens (Expression of Interest application forms will be made available on our website)
– Wednesday 24 March: Expression of Interest due
The Sanfilippo Children’s Foundation is particularly interested in three focus areas:
– halt disease progression through therapies such as enzyme replacement, gene therapy and cell therapy and strategies to enhance the effectiveness of such emerging therapies
– repair and reverse the cell damage caused by Sanfilippo Syndrome, which could include the application of neuroregeneration advances made for other neurodegenerative diseases
– improve quality of life through palliative care and symptom management specific to Sanfilippo Syndrome
More information about our research strategy and funding program can be found on our website: https://www.sanfilippo.org.au/research/research-funding-program
The purpose of the Sanfilippo Children’s Foundation is to drive research for a world without Sanfilippo Syndrome.
This will be achieved by:
- Funding research which might halt progression of the condition, reverse damage caused or improve quality of life for patients with the condition;
- Providing clear, accurate and up-to-date information to diagnosed families regarding the disease, therapeutic avenues and current research programs;
- Raising awareness of the disease amongst the community, including the medical profession;
- Advocating for improved outcomes for the Sanfilippo patient community;
- Improving the diagnosis path – more accurate and earlier diagnosis to enable appropriate treatment.
Researchers at the University of Gdańsk, Poland have conducted tests that show certain genes in the DNA of MPS patients render their cells less susceptible to COVID-19 infection than normal cells, though the typical – for storage diseases – narrowing of the respiratory tract and presence of thick mucous are still risk factors for infection.

Present and former LDN Members will present a series of studies and insights relating to lysosomal diseases at the 16th annual WORLDSymposium to be held from February 10-13, 2020 in Orlando, Florida. WORLDSymposium is designed to help researchers and clinicians to better manage and understand diagnostic options for patients with lysosomal diseases, identify areas requiring additional basic and clinical research, public policy and regulatory attention, and identify the latest findings in the natural history of lysosomal diseases.
