Mucopolysaccharidosis (MPS) type II (MPS II; Hunter syndrome) is a rare, X-linked disease caused by a deficiency of the lysosomal enzyme iduronate-2-sulfatase (I2S) and occurs almost exclusively in boys, with an incidence of approximately 1.3 per 100,000 live male births.1 Early identification of MPS II is challenging because some initial features, such as chronic runny nose, otitis media, and hernias, are commonly seen in the general population. As a result, even though the signs and symptoms of MPS II typically appear early in childhood, the diagnosis may lag behind by several years.

The primary objective of this international multi-center study is to evaluate the positive screening rate of MPS II subjects by screening a high-risk male pediatric population who have had or are scheduled for 1 or more specific ENT surgical procedures (adenoidectomy and/or tonsillectomy and/or tympanostomy) and who have a previously repaired or present evidence of an inguinal and/or umbilical hernia.

Enrollment: 160
Study Start Date: March 2014
Estimated Study Completion Date: September 2018
Estimated Primary Completion Date: August 2018 (Final data collection date for primary outcome measure)
Analysis population
All subjects enrolled in the study who meet the eligibility criteria

Detailed Description:
With evidence-based information from MPS registries regarding the types of surgical interventions that are most prevalent in MPS, this screening study is expected to provide the understanding of the role pediatric ENT surgeons can play in identifying young children with MPS.

Ages Eligible for Study:   up to 7 Years   (Child)
Sexes Eligible for Study:   Male
Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample
Study Population
Males of any ethnic background or race, <7 years of age or under, who have had or are scheduled for adenoidectomy and/or tonsillectomy and/or tympanostomy (alone or in combination), will be enrolled. In addition, the subjects must have previous surgical repair or presence of inguinal and/or umbilical hernia.

Inclusion Criteria:

Each subject must meet the following criteria to be enrolled in this study:

  1. The subject is male.
  2. The subject is <7 years of age.
  3. The subject has had or is scheduled for ENT surgery for any of the following, alone or in combination: adenoidectomy, tonsillectomy, and tympanostomy.
  4. The subject has record of previous surgical repair or presence of inguinal and/or umbilical hernia.
  5. The subject's parent(s) or the subject's legally authorized representative(s) has provided written informed consent that has been approved by the Institutional Review Board/Independent Ethics Committee (IRB/IEC).

Exclusion Criteria:

Subjects who meet any of the following criteria will be excluded from the study:

  1. The subject has a current confirmed diagnosis of any MPS disorder.
  2. The subject was born prematurely (defined as born before 37 weeks gestation).
  3. The subject has received a blood transfusion within the past 6 weeks.
  4. The subject has received a bone marrow transplant.
