Novel multispectral imaging to predict disease progression in pediatric morphea

Area of Science:

• Dermatology
• Medical Imaging
• Pediatrics

Background:

• Morphea (localized scleroderma) is a progressive, debilitating inflammatory skin disorder.
• Infrared thermography often yields false positive results for morphea.
• Accurate prediction of disease progression is crucial for effective management.

Purpose of the Study:

• To evaluate multispectral imaging's ability to predict disease progression in pediatric morphea.
• To compare multispectral imaging findings with clinical assessments.

Main Methods:

• 17 children with morphea underwent multispectral imaging using an Antera™ 3D camera.
• Clinical data were collected using the Localized Scleroderma Assessment Tool (LoSCAT).
• Hemoglobin gradients between affected and unaffected skin were correlated with disease progression over 3-month follow-ups.

Main Results:

• A significantly higher hemoglobin gradient was observed in children with morphea progression (average differential 0.3) compared to those without (average differential 0.08).
• Multispectral imaging achieved 90% sensitivity and 100% specificity in detecting progression using a 0.18 hemoglobin gradient cutoff.
• The study included children aged 6-18 years, predominantly female and white, with linear or plaque morphea.

Conclusions:

• Multispectral imaging shows promise as a novel, accurate tool for predicting pediatric morphea progression.
• It can serve as an adjunct to clinical assessment in managing localized scleroderma.
• Further research is recommended to compare its performance with thermography.
