Tidsramme |
|---|---|---|
|
PDUS
Tidsramme: Baseline, Week 2, Month 3
|
30 joints will be evaluated using a 0 to 3 point scale for each joint and the sum of these represents PDUS.
The Power Doppler Synovitis Score (PDUS) ranges from 0 to 90.
Scores of 0 indicate the least amount of inflammation of the joint while scores of 3 indicate the most amount of inflammation.
A higher value of the total score for PDUS represents more severe disease level.

Baseline, Week 2, Month 3
|
|
GSUS
Tidsramme: Baseline, Week 2, Month 3
|
30 joints will be evaluated using a 0 to 3 point scale for each joint and the sum of these represents GSUS.
The grey scale synovial hypertrophy score (GSUS) ranges from 0 to 90.
Scores of 0 indicate the least amount of inflammation of the joint while scores of 3 indicate the most amount of inflammation.
A higher value of the total score for GSUS represents more severe disease level.
|
Baseline, Week 2, Month 3
|
|
CDAI
Tidsramme: Baseline, Week 2, Month 3
|
CDAI was derived as the sum of the following: tender joint count (TJC), swollen joint count (SJC), participant global assessment (PGA) of disease activity, and physician assessment of disease activity.
TJC and SJC were taken as the number of tender and swollen joints, respectively, out of 28 assessed joints.
PGA and physician assessment of disease activity were scored 0-100 millimeters (mm) and rounded to the nearest centimeter (cm) on a visual analog scale (VAS), where higher scores indicate greater perceived disease activity.
The total CDAI score range was 0-76, where higher scores indicate increased disease activity.

DAS28/ESR
Tidsramme: Baseline, Week 2, Month 3
|
TJC and SJC were taken as the number of tender and swollen joints, respectively, out of 28 assessed joints.
Patient Global Assessment of disease activity was scored 0-100 millimeters (mm) and rounded to the nearest centimeter (cm) on a visual analog scale (VAS), where higher scores indicate greater perceived disease activity.
ESR lab value were included in the total calculation.
The scale being used is called the Disease Activity Score for 28 Joints (DAS28) using the Erythrocyte Sedimentation Rate (ESR) in the calculation.The scale ranges from 0 to 9.4, where higher values represent a higher disease activity.The complete formula to calculate DAS28/ESR is 0.56*sqrt(TJC) + (0.28*sqrt(SJC)) + (0.7*ln(ESR)) + (0.014*Patient Global*10).

MBDA
Tidsramme: Baseline, Week 2, Month 3
|
The multi-biomarker disease activity (MBDA) blood test assesses RA disease activity.
An algorithm of 12 markers is used to characterize RA disease activity on a scale of 1-100, where a score of 100 represents the highest level of disease activity present.
