Outcome Measures
Primary Outcomes (1)
Contraction Rate
The contraction rate is measured as lymphatic vessel contractions/min in the dominant lymphatic vessel efferent to the injection site using the MultiSpectral Imaging System (MSImager) that captures real time movies. The MSImager software analyses the signal intensity to determine the contraction rate.

Study Arms (2)
Developmental arm - Healthy or rheumatoid arthritis subjects
EXPERIMENTALSubjects in the developmental arm will have a minimum of two study visits to determine the optimal conditions for visualizing lymphatic transport in the upper extremities. Concentrations of 0.1 mg/ml of Indocyanine Green (ICG) will be injected intradermally into the web spaces of the hands in both upper extremities. Multispectral video and still images will be recorded using the MultiSpectral Imaging System (MSImager). An ultrasound of the upper extremities may be performed after the ICG fluorescence is observed. The exam will help identify the location of the lymphatic vessels and nodes in the areas fluoresced.
Clearance arm - Healthy individuals
EXPERIMENTALSubjects in the clearance arm will have an initial study visit that involves injections of 0.1 mg/ml of Indocyanine Green (ICG) intradermally into the web spaces of the hands in both upper extremities. Multispectral video and still images will be recorded using the MultiSpectral Imaging System (MSImager). Follow up imaging sessions will occur weekly for three weeks for a minimum of four study visits total.
Interventions
A trained physician will inject 0.1 ml of Indocyanine Green into the web spaces of the hands in both upper extremities. Subjects may have up to five study visits to confirm feasibility, safety, and reproducibility.
Once the Indocyanine Green is injected, the contrast is expected to fluoresce underneath the MultiSpectral Imaging System. Multispectral video and still images will be recorded at the study visits.
Eligibility Criteria
You may qualify if:
- Ability to provide written informed consent
- Subjects can be either gender but must be at least 18 years old.
- Rheumatoid arthritis subjects may fulfill 2010 American College of Rheumatology criteria.
- Active rheumatoid arthritis subjects, with at least 2 tender or swollen joints.
- Subjects participating in the clearance arm of the study must not have ICG injections for at least 10 weeks.
You may not qualify if:
- Individuals with active systemic disorders or inflammatory conditions other than rheumatoid arthritis, (such as chronic infections with hepatitis B, hepatitis C or HIV) that would confound the study results.
- Known sensitivity to iodine because of residual iodide in Indocyanine Green
- Pregnant women should not participate.
