Clinical Trial Summary

This study is being done to learn how many children and young adults who come to pediatric rheumatology clinics may have mucopolysaccharidosis (MPS). The study tests for 4 of the types of MPS: I, II, IVA, and VI. This can help researchers decide whether to create a screening program for MPS at pediatric rheumatology clinics. This study is being done in rheumatology clinics because the first symptoms of MPS are often joint problems such as stiff joints, and rheumatologists may be the first doctors that a patient with MPS visits. The study will also evaluate the utility of dried blood spot testing for MPS.

Description:

MPS, or mucopolysaccharidosis (mew-co-paw-lee-sack-a-rid-o-sis), disorders are a group of rare inherited diseases that affect about 1 in every 25,000 people in the United States. There are 7 MPS disorders: MPS I (Hurler, Hurler-Scheie, and Scheie syndromes), II (Hunter syndrome), III (Sanfilippo syndrome), IV (Morquio syndrome), VI (Maroteaux-Lamy syndrome), VII (Sly syndrome), and IX (no other name). In people who have MPS, the body cannot break down certain materials in the body's cells. These materials then build up in the cells, causing problems such as stiff joints, misshapen bones, curled hands and reduced hand function, frequent ear infections, vision and hearing problems, "thickened" facial features, and heart problems. Getting access to diagnosis and treatment can help make MPS easier to manage; but unfortunately, people with MPS may go undiagnosed for many years.

This study is being done to learn how many children and young adults who come to pediatric rheumatology clinics may have mucopolysaccharidosis (MPS). The study tests for 4 of the types of MPS: I, II, IVA, and VI. This can help researchers decide whether to create a screening program for MPS at pediatric rheumatology clinics. This study is being done in rheumatology clinics because the first symptoms of MPS are often joint problems such as stiff joints, and rheumatologists may be the first doctors that a patient with MPS visits.

The study will use dried blood spot (DBS) testing to screen for these types of MPS. It will also use a survey to evaluate the utility and convenience of dried blood spot testing for MPS.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Incidence of previously unrecognized MPS I, II, IVA, and VI in children presenting to pediatric rheumatology, hand, or skeletal dysplasia clinics	Each patient is screened for MPS I, II, IVA, and VI after enrolling in the study. The results for all patients will be pooled when the study is completed (expected completion approx. 18 months after the study begins).	At study completion (approximately 18 months after the beginning of the study)	No
Secondary	Utility of DBS testing to screen for MPS in pediatric patients	For the secondary endpoint (utility of DBS testing), the following data will be collected: ease of taking and sending the DBS sample; number of errors of sample taking; adverse events (if any) associated with blood sampling by finger prick or venipuncture (for subjects over one year of age; choose whichever method is most convenient) or heel prick (for subjects under one year of age); and comfort of patients and/or their parents with the test.; Study personnel who performed DBS testing will also be asked to complete a brief survey about the utility of DBS testing.	At study completion (approximately 18 months after the beginning of the study)	Yes
