Condition(s) targeted: X-linked Hypohidrotic Ectodermal Dysplasia; Hypohidrotic Ectodermal Dysplasia
Phase: N/A
Status: Completed

Summary
The study proposes to enroll male subjects affected by Hypohidrotic Ectodermal Dysplasia
(XLHED). The sweat duct images will be acquired with a CE marked skin-imaging device and the
sweat rate will be measured using a CE marked pilocarpine iontophoresis and collection
system. The technologies for both imaging of sweat ducts and the measurement of maximal
sweat rate have been used safely and without adverse events in our prior studies involving
HED/XLHED subjects. Furthermore, this study will assess the feasibility of developing a
non-invasive screening tool that will enable detection of clinical signs of XLHED based on
an analysis of a two dimensional frontal photograph.
Clinical Details
Official title: Evaluation of Phenotypic and Genetic Properties in Male Subjects Affected By Hypohidrotic Ectodermal Dysplasia (ECP-012)
Study design: N/A
Primary outcome: Collecting demographic and clinical status information in XLHED affected males and unaffected male siblings using a medical questionnaire and clinical photographsAssess the feasibility of developing a non-invasive newborn screening tool, which will enable detection of clinical symptoms of HED/XLHED at birth, based on an analysis of a two dimensional photograph
Secondary outcome: The secondary objective of this descriptive study is to use skin assessment techniques to characterize skin properties in male subjects affected by XLHED compared with unaffected male sibling controls, including determination of the number of sweat ducts
Detailed description:
The study proposes to enroll male subjects affected by XLHED (determined by genetic testing
and restricted to age > 1 yr). The sweat duct images will be acquired with a CE marked
skin-imaging device and the sweat rate will be measured using a CE marked pilocarpine
iontophoresis and collection system. The technologies for both imaging of sweat ducts and
the measurement of maximal sweat rate have been used safely and without adverse events in
our prior studies involving HED/XLHED subjects. Furthermore, this study will assess the
feasibility of developing a non-invasive screening tool that will enable detection of
clinical signs of XLHED based on an analysis of a two dimensional frontal photograph.
Eligibility
Minimum age: 1 Year.
Maximum age: N/A.
Gender(s): Male.
Criteria:
Inclusion Criteria:
Subjects must meet all of the following criteria to be enrolled in this study.
- Attending the 2012 Spanish Association for those Affected by Ectodermal Dysplasia
Annual Reunion;
- One year of age or greater;
- Conform to one of the following requirements for providing informed consent/assent:
- If more than 18 years of age, subjects must provide signed informed consent;
- If less than 18 years of age and it is determined that the subject is capable of
providing assent, both the assent of the subject and consent of the parent(s) or
guardian of that subject must be granted. Under this condition, both parents of
the subject should give their permission, unless 1 parent is deceased, unknown,
incompetent, or not available;
- If the subject is incapable of providing assent, the consent of the parent(s) or
guardian of the subject must be granted. Under this condition, both parents
should give their consent, unless 1 parent is deceased, unknown, incompetent, or
not available.
- Can provide documentation of genetic testing results positive for an EDA gene
mutation /deletion;
- As described in Section 3. 2 above, subjects must meet one of the following criteria:
- Documented diagnosis of XLHED confirmed via genetic testing;
- Unaffected male controls.
Exclusion Criteria:
- Known hypersensitivity to pilocarpine or pilocarpine-like muscarinic agonists;
- Presence of pacemakers;
- Subjects who are not able or are not willing to comply with the procedures of this
protocol;
- Subjects with any major medical problem that will prevent them from participating in
this study.
