Primary Outcome Measures

Outcome Measures in Rheumatoid Arthritis Clinical Trials (OMERACT) Rheumatoid Arthritis Magnetic Resonance Imaging Scoring System (RAMRIS) Synovitis Score
Extension and degree of synovitis in wrist according to RAMRIS score developed by OMERACT. Synovitis is an area in synovial compartment that shows above normal post-gadolinium enhancement of a thickness greater than width of normal synovium. Synovitis is assessed in 3 wrist regions (distal radioulnar joint; radiocarpal joint; intercarpal and carpometacarpal joints) and in each metacarpophalangeal (MCP) joint. 1st carpometacarpal joint and 1st MCP joint are not scored. Score 0 is normal, and 1-3 (mild, moderate, severe) are by thirds of the presumed maximum volume of enhancing tissue in the synovial compartment. Total synovitis score=the sum of the individual scores (3 wrist regions [range 0-9] or 4 MCP joints [range 0-12]) for an overall range of 0-21, where 0=no damage and maximum score [9, 12, or 21]=most severe damage. Change in synovitis = Follow-up synovitis score - baseline score.
OMERACT RAMRIS Bone Edema Score
Extension and degree of bone edema in the wrist according to the RAMRIS score developed by OMERACT. Bone edema is a lesion within the trabecular bone, with ill-defined margins and signal characteristics consistent with increased water content. Each bone (wrists: carpal bones, distal radius, distal ulna, metacarpal bases; MCP joints: metacarpal heads, phalangeal bases) is scored separately. The scale of 0-3 was based on the proportion of bone with edema, as follows: 0=no edema; 1=1 percent (%) to 33% of bone was edematous; 2 = 34%-66% of bone was edematous; and 3= 67%-100% of bone was edematous. Total bone edema score=sum of the individual scores for an overall range of 0-69, where 0=no edema and 69=most severe edema. Change in bone edema = follow-up bone edema score - baseline score.
OMERACT RAMRIS Erosion Score
MRI bone erosion measures a sharply marginated bone lesion, with correct juxta-articular localization and typical signal characteristics, which is visible in 2 planes with a cortical break seen in at least 1 plane. Each bone (wrists: carpal bones, distal radius, distal ulna, metacarpal bases; MCP joints: metacarpal heads, phalangeal bases) scored separately. Scale is 0-10 based on proportion of eroded bone compared to assessed bone volume (0=no erosion; 1=1%-10% of bone eroded; 2=11%-20%, etc). For long bones, assessed bone volume is from articular surface (or best estimated position if absent) to depth of 1 centimeter (cm); in carpal bones it is the whole bone. Total erosion score=sum of individual scores for an overall range of 0-230, where 0=no erosion and 230=most severe erosion. Change in erosion=Follow-up erosion score - baseline score.
Early Enhancement Rate (REE)
A low cost, low field dedicated extremity MRI unit was used, which is specifically designed for the examination of peripheral joints. In addition to the standard OMERACT-RAMRIS scoring system, additional data were elaborated by using "dynamic" MRI, i.e. Contrast-Enhanced Dynamic MRI (DCE-MRI). This method evaluates the diffusion of the contrast mean in a series of very short sequences thus providing a diffusion curve which is proportionate to the extent of inflammation in the synovial membrane. Numerical parameters used with this method are the slope in the initial phase (rate of early enhancement - REE) and its "steady state" condition (relative enhancement - RE). REE per second during the first 55 seconds was calculated according to the formula REE55 = (S55-S0)/(S0x55)x100%. The REE shows the slope of the curve of contrast uptake tangential to the α angle and is steeper if inflammation is higher.
Relative Enhancement (RE) Score
A low cost, low field dedicated extremity MRI unit was used, which is specifically designed for the examination of peripheral joints. In addition to the standard OMERACT-RAMRIS scoring system, additional data were elaborated by using "dynamic" MRI (DCE-MRI). This method evaluates the diffusion of the contrast mean in a series of very short sequences thus providing a diffusion curve which is proportionate to the extent of inflammation in the synovial membrane. Numerical parameters used with this method are the slope in the initial phase (REE) and its "steady state" condition (RE).

Secondary Outcome Measures

Ritchie Articular Index Scores
The Ritchie Articular Index is a graded assessment of tenderness in 26 joint regions. The sum of the grades of tenderness (0=not tender, 1=tender, 2=tender and causes wince, and 3 tender, causes wince and effort to withdraw) elicited by applying firm pressure over the joint margin of articular joints (such as shoulders, elbow, wrists, hips). The scores ranged from 0 (no tenderness) to 78 (most severe tenderness).
Health Assessment Questionnaire - Disability Index (HAQ-DI) Score
The Stanford HAQ-DI is a participant-reported questionnaire specific for rheumatoid arthritis (RA). It consist of 20 items referring to eight component sets: dressing/grooming, arising, eating, walking, hygiene, reach, grip, and activities. Each item within a domain was scored on a 4-point Likert scale from 0 to 3: 0 = no difficulty; 1 = some difficulty; 2 = much difficulty; 3 = unable to do. The highest score reported by the participant for a domain determined the score for that domain. The overall disability index is computed as the sum of domain scores and divided by the number of domains answered. Total possible score range 0-3 where 0 = least difficulty and 3 = extreme difficulty.
Patient's Global Assessment of Pain
The participant's assessment of their current level of pain on a 0 to 100 millimeter (mm) horizontal VAS. The left-hand extreme of the line was described as "no pain" and the right-hand as "unbearable pain". The participant was asked to mark the line corresponding to their current level of pain and the distance from the left edge was recorded.
DAS28 Score
DAS28 calculated from the number of swollen joints and tender joints using the 28-joints count, the erythrocyte sedimentation rate (ESR) (millimeters per hour [mm/hr]) and Patient's Global Assessment of Disease Activity (participant-rated arthritis activity assessment) with transformed scores ranging 0 to 10; higher scores indicated greater affectation due to disease activity. A DAS28 score of less than or equal to (≤) 3.2 = low disease activity, a DAS28 score of >3.2 to 5.1 = moderate to high disease activity.
Erythrocyte Sedimentation Rate (ESR)
ESR was determined using the Westergren method. ESR measures how fast red blood cells (erythrocytes) fall to the bottom of a fine glass tube that is filled with the participant's blood. The higher the sedimentation rate the greater the inflammation.
C-Reactive Protein (CRP)
CRP measured by milligrams per deciliter (mg/dL). High levels of CRP are indicators of active inflammation.
Anti-Cyclic Citrullinated Peptide (Anti-CCP) Autoantibodies Count
Anti-CCP autoantibodies count measured by units per milliliter (U/mL). The anti-CCP autoantibodies bind antigenic determinants that contain the unusual amino acid citrulline. The anti-CCP antibody is a highly specific diagnostic test of RA (though with variable sensitivity) and a marker of joint damage with high prognostic significance.
Rheumatoid Factor (RF) Immunoglobulin M (IgM) Concentrations
RF IgM concentrations measured by international units per milliliter (IU/mL). RF is an antibody reacting against the fragment, crystallizable (Fc) region of IgG. Quantitative measurements have shown a prognostic value in distinguishing between progressive and non-progressive disease in early RA, a correlation with radiologically determined joint damage, and relation with clinical improvement after disease-modifying anti-rheumatic treatment.
Total Immunoglobulin (Ig) Concentrations
Total Ig concentrations as measured by milligrams per milliliter (mg/mL).
Hematocrit Concentration (%)
Percentage of Total B-lymphocytes
Concentration of all B-lymphocytes subtypes was assessed.
Erosion Score - Right Hand
The erosion score per joint of the hands can range from 0 to 5. Erosions were scored 1 if they were discrete but clearly present, and 2 or 3 if they were larger, depending on the surface area of the joint involved. A score of 3 was given if the erosion was large and extended over the imaginary middle of the bone. A score of 5 was given if a complete collapse of the joint was present or if the full surface of the joint was affected. In each joint, individual erosions were summed up to a maximum of 5. The maximal erosion score for each hand was thus 80, considering the 16 areas for erosions per hand.
Erosion Score - Left Hand
The erosion score per joint of the hands can range from 0 to 5. Erosions were scored 1 if they were discrete but clearly present, and 2 or 3 if they were larger, depending on the surface area of the joint involved. A score of 3 was given if the erosion was large and extended over the imaginary middle of the bone. A score of 5 was given if a complete collapse of the joint was present or if the full surface of the joint was affected. In each joint, individual erosions were summed up to a maximum of 5. The maximal erosion score for each hand was thus 80, considering the 16 areas for erosions per hand.
Joint Space Narrowing - Right Hand
Joint space narrowing and joint subluxation or luxation are combined in a single score with a range of 0 to 4. A normal joint space was scored 0. A score of 2 was allowed to a focal narrowing of the joint or to a joint space not sufficiently narrowed to be scored 2. The score of 1 was not to be used when the reader was unsure whether there was joint space narrowing. A generalized narrowing leaving more than 50% of the original joint space present was scored 2. A generalized narrowing leaving less than 50% of the original joint space present was scored 3, and a subluxation of a joint was also scored 3. A bony ankylosis or a complete luxation of the joint was scored 4. A total of 13 joints were evaluated for narrowing and the scores were summed (13 times [x] 4 [maximum per joint]). Each sum was normalized to a scale of 0 (best possible outcome) to 100 (worst possible outcome).
Joint Space Narrowing - Left Hand
Joint space narrowing and joint subluxation or luxation are combined in a single score with a range of 0 to 4. A normal joint space was scored 0. A score of 2 was allowed to a focal narrowing of the joint or to a joint space not sufficiently narrowed to be scored 2.

Each sum was normalized to a scale of 0 (best possible outcome) to 100 (worst possible outcome).
X-Rays: Right Hand Total Score
Right hand total scores as measured by X-rays examining erosion and joint space narrowing. Total score was calculated as the sum of the erosion score and the joint space narrowing score and scores ranged from 0 (best possible outcome) to 180 (worst possible outcome).
X-Rays: Left Hand Total Score
Left hand total scores as measured by X-rays examining erosion and joint space narrowing. Total score was calculated as the sum of the erosion score and the joint space narrowing score and ranged from 0 (best possible outcome) to 180 (worst possible outcome).
