Child Clinical Trial - Non-invasive Optical Detection of Iron Deficiency

Status Completed

Clinical Trial Summary

This study aims to evaluate a prototype device detecting zinc protoporphyrin-IX fluorescence non-invasively from the intact oral mucosa in children. The prototype device has shown high sensitivity and specificity in women after delivery for iron deficiency. Children are at increased risk for iron deficiency and prevention methods are not established jet. Zinc protoporphyrin-IX is an early indicator of iron deficiency and may be more sensitive than other established parameters. The prototype device is used to measure the erythrocyte zinc protoporphyrin-IX/heme ratio in children aged 9 months to 5 years. Children in this age are at increased risk for iron deficiency as they are growing rapidly and iron deficiency in this age may affect the neurodevelopment and immune system adversely. It is proposed that these effects cannot be rectified by iron supplementation in later years. The results from the non-invasive measurements are compared to reference measurements of the erythrocyte zinc protoporphyrin-IX/heme ratio from residual blood samples from the same patients and to other indicators of iron status, including hemoglobin, ferritin, serum iron, transferrin, transferrin saturation and soluble transferrin receptor.

Clinical Trial Description

This trial is a proof-of-concept study using a prototype fiber optic fluorometer to acquire autofluorescence spectra in children aged 9 months to 5 years and determine the erythrocyte zinc protoporphyrin-IX fluorescence intensity from these spectra. The non-invasively determined fluorescence spectra are evaluated to provide a quantitative measure of the erythrocyte zinc protoporphyrin-IX/heme concentration ratio. These values are primarily compared to an erythrocyte zinc protoporphyrin-IX determined by HPLC from residual blood samples from the same subjects and secondarily to erythrocyte zinc protoporphyrin-IX/heme ratios determined using a commercial hematofluorometer (AVIV, model 206d) and other indicators of iron status, including hemoglobin, ferritin, serum iron, transferrin, transferrin saturation and soluble transferrin receptor

This study could help to establish the non-invasive fluorescence measurement of zinc protoporphyrin-IX as a rapid, easy to use means for point-of-care screening for iron deficiency in resource-limited settings lacking laboratory infrastructure. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
