Evaluation of Scanoskin for the Assessment of Vitiligo

September 27, 2019 updated by: Chelsea and Westminster NHS Foundation Trust

Comparison of Scanoskin With Planimetry as an Objective Measure of Vitiligo.

The aim of this study is to establish whether the use of a special digital camera (SIAscopy) can provide an accurate and reliable measure of vitiligo which is at least equivalent to the current gold standard of planimetry. If so, SIAscopy could be used as an objective diagnostic and prognostic tool in the management of vitiligo patients within dermatology departments and allow a fair and accurate assessment of new potential treatments.

Detailed Description

Vitiligo is a common, disfiguring skin complaint which affects between 0.5 and 2% of the world population and which presents with de-pigmented patches of skin. Highly stigmatising it has a profound psychological impact on those affected and negatively impacts quality of life. Efficacy of current therapies which include topical steroids/calcineurin inhibitors and ultraviolet light are limited and new treatments are required. Numerous papers including the 2010 Cochrane review have highlighted the need for a consensus on outcome measures which could then facilitate meta-analyses and provide robust clinical recommendations. No standard method of measuring skin re-pigmentation has been identified to date and current best practice relies on clinician assessment and use of various non-standardised grading systems (of which there are over 40 none of which has been proven superior or accepted by the consensus of clinicians) and in addition are neither robust nor objective. Measurement of skin pigment levels can be achieved using portable devices such as Spectrophotometric Intracutaneous Analysis scope (SIAscope) using an imaging modality called ScanoskinTM. Unlike other digital methods reported in the literature, this has been validated as a quantitative measure of melanin content in the skin, it is portable, easy to use and not prohibitively expensive. The aim of this study is to determine if ScanoskinTM is equivalent to the current gold standard of planimetry (mainly used in research setting) for establishing extent of vitiligo. In addition the investigators want to assess whether it offers a more objective standardised measure of vitiligo compared with clinician assessment (current accepted best clinical practice) which could then be utilised to provide a meaningful assessment of new and existing treatment modalities. In addition the investigators will assess whether ScanoskinTM is able to identify subclinical disease which could affect clinical decisions regarding treatment strategies and also assess whether improvements in pigmentation correlate with patient satisfaction and quality of life scores.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 100 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

Study Population

All adult patients attending outpatient dermatology clinics at Chelsea & Westminster Hospital and diagnosed with vitiligo will be invited to take part in the study

Description

Inclusion Criteria:

  • Adult patients diagnosed with vitiligo (any form) by a Consultant Dermatologist/Specialist Dermatology trainee.
  • Who undergo any form of treatment or observation.
  • Informed consent for enrolment into the study.
  • Referred for assessment and treatment at Chelsea & Westminster Hospital Dermatology Department.

Exclusion Criteria:

  • Patients not consenting to participate.
  • Patients with insufficient English to comprehend the Patient Information Sheet (regrettably we are unable to offer translation services for this scope).
  • Patients without capacity to comprehend the Patient Information Sheet would be deemed unable to give informed consent and therefore not included.
  • Patients unable to undertake the imaging process for whatever reason.
  • Patients unable to attend for follow up assessment

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Comparison of Scanoskin with planimetry as an objective measure of vitiligo.
Time Frame: 3 years
Comparing planimetry to Scanoskin ability to work out surface area and percentage pigmentation of vitiligo lesions
3 years

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Determine whether Scanoskin can identify subclinical disease
Time Frame: 3 years
Taking standardised Scanoskin images of unaffected skin over time to determine if Scanoskin can pick up subclinical disease
3 years
