Trial summary

The skin of pre-term neonates is not fully developed and often leads to trans-epidermal water loss, trouble regulating temperature, and increased risk of skin wounds. Current treatment decisions are based on subjective, qualitative assessments of the skin. Read more about this study

About this study

Official title: Characterization of Pre-Term Neonatal Skin by Diffuse Reflectance Spectroscopy Pilot Study

The skin of pre-term neonates is not fully developed and often leads to trans-epidermal water loss, trouble regulating temperature, and increased risk of skin wounds. Current treatment decisions are based on subjective, qualitative assessments of the skin. The purpose of this pilot study is to evaluate the utility of non-invasive optical spectroscopy methods to collect key biological information from neonatal skin, including skin maturity, blood oxygenation, and bilirubin content. Parents of pre-term neonatal subjects (n=44) will be recruited for consent to participate, and spectral measurements will be made with a diffuse reflectance spectrometer(DRS) device previously approved by the University of Arkansas for Medical Sciences Institutional Review Board. The spectral data will be analyzed to extract parameters related to tissue light scattering, oxy-and deoxy-hemoglobin, melanin, and bilirubin. The system will be validated by comparing extracted spectra with expected literature values and directly correlating the measured bilirubin levels with readouts from the current University of Arkansas for Medical Sciences practice standard: Philip's BiliChek. The long-term goal is to develop and use non-invasive optical readouts to predict and monitor skin dysfunction in the Neonatal Intensive Care Unit (NICU).

Read the detailed description

This is a cross-sectional, pilot study to characterize the response of neonatal premature skin to DRS when excited with a white light source, and provide a baseline of how the collected spectra change with the maturation of the epidermal layer in the weeks to term gestation after birth. DRS spectra and BiliChek measurements will be performed on the study population admitted to the Neonatal Intensive Care Unit. The pilot data will be used to evaluate whether Diffuse Reflectance Spectroscopy spectra can be used to extract optical information on skin maturity as well as hemoglobin, melanin, and bilirubin concentrations. The investigators will extract spectra for each chromophore and the relative concentration from the Diffuse Reflectance Spectroscopy measurements. Extracted Diffuse Reflectance Spectroscopy spectra will be compared to published absorbance spectra for each chromophore. The criteria for success will be a high, positive correlation (r ≥ 0.85) between the extracted Diffuse Reflectance Spectroscopy bilirubin concentration and BiliChek-derived concentration.

The following coded data will also be collected to investigate correlations with the Diffuse Reflectance Spectroscopy spectra: blood oxygen saturation, weight, ethnicity, corrected age, gestational age, sex, most recent complete blood count (if available, or partial count if not), most recent chemistry levels, lipids, liver profile, and blood gas (all if available). BiliChek measurements of bilirubin content will be compared to the extracted bilirubin contribution measured from the Diffuse Reflectance Spectroscopy spectra using linear regression and assessed using Pearson's correlation coefficient.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Bilirubin Concentration From Non-invasive Diffuse Reflectance Spectroscopy (DRS) vs BiliChek

    Number of participants with premature skin assessed with Diffuse Reflectance Spectroscopy, comparing bilirubin concentration levels/readings produced by DRS system with readouts from the current UAMS practice standard (Philip's BiliChek) using a linear regression and a Pearson's correlation coefficient assessment.

    Measured: 15 Minutes

Secondary outcomes (3)
  1. Hemoglobin Readings From Diffuse Reflectance Spectroscopy (DRS) Spectra Compared With Expected Values

    Compare hemoglobin readings from the DRS system's extracted spectra with expected values by gestational age, race, ethnicity, and sex using a linear regression and a Pearson's correlation coefficient assessment.

    Measured: approximately one day per subject

  2. Melanin Readings From Diffuse Reflectance Spectroscopy (DRS) Spectra Compared With Expected Values

    Compare melanin readings from the DRS system's extracted spectra with expected values by gestational age, race, ethnicity, and sex using a linear regression and a Pearson's correlation coefficient assessment.

    Measured: approximately one day per subject

  3. Bilirubin Readings From Diffuse Reflectance Spectroscopy (DRS) Spectra Compared With Expected Values

    Compare bilirubin readings from the DRS system's extracted spectra with expected values by gestational age, race, ethnicity, and sex using a linear regression and a Pearson's correlation coefficient assessment.

    Measured: approximately one day per subject
