Plasma Exchange With Standard Glucocorticoids
Plasma Exchange: Plasma exchange is a procedure whereby blood is taken from the body and separated by a machine into blood cells and plasma, which is the liquid part of blood. The plasma is discarded and the blood cells are returned to the body with a plasma substitute. Glucocorticoids: During the study, a standard glucocorticoids dose regimen will be compared to a reduced glucocorticoids dose regimen. All subjects' patients will receive the same glucocorticoids dose for the first two weeks then will follow a standard regimen.
Plasma Exchange With Reduced Glucocorticoids
Plasma Exchange: Plasma exchange is a procedure whereby blood is taken from the body and separated by a machine into blood cells and plasma, which is the liquid part of blood. The plasma is discarded and the blood cells are returned to the body with a plasma substitute. Glucocorticoids: During the study, a standard glucocorticoids dose regimen will be compared to a reduced glucocorticoids dose regimen. All subjects' patients will receive the same glucocorticoids dose for the first two weeks then the dose will decrease to a reduced regimen.
No Plasma Exchange With Standard Glucocorticoids
Participants in this arm do not undergo plasma exchange. Glucocorticoids: During the study, a standard glucocorticoids dose regimen will be compared to a reduced glucocorticoids dose regimen. All subjects' patients will receive the same glucocorticoids dose for the first two weeks then follow a standard regimen.
No Plasma Exchange With Reduced Glucocorticoid
Participants in this arm do not undergo plasma exchange. All subjects' received the same glucocorticoids dose for the first two weeks, then the dose was decreased following a reduced glucocorticoid dose regimen.

EuroQoL-5 Dimensions consist of 2 elements: the EQ-5D descriptive system and the EQ visual analogue scale (EQ VAS). The EQ-5D descriptive system comprised of following 5 dimensions: 1.Mobility, 2.Self-Care, 3.Usual Activities, 4.Pain/Discomfort and 5.Anxiety/Depression. Each of these 5 dimensions has 5 levels: 1: no problems; 2: slight problems; 3: moderate problems; 4: severe problems; 5: Unable to do. The digits for each of 5 dimensions were combined in a 5-digit number describing the participant's health state: e.g. state 11111 indicates no problem on any of the 5 dimensions. Health state index scores generally range from less than 0 (where 0 is a health state equivalent to death; negative values are valued as worse than death) to 1 (perfect health), with higher scores indicating higher health utility.
