Detailed Description

IgG4-related disease (IgG4-RD) is a chronic autoimmune disease with a relapsing-remitting course. For patients in remission, glucocorticoid (GC) and immunosuppressant are used to be maintained for a long time in fear of disease flare. Long-term GC and immunosuppressant could bring a lot of side-effects and economic burden. Whether and when patients with stable disease should withdraw GC or immunosuppressant? How about the relapse risk respectively? What are the risk factors for disease flare? All the above remain unclear. The aim of this study is to explore the relapse risk after GC or immunosuppressant withdrawal in IgG4-RD patients with stable disease and to establish a predictive model for risk stratification. Meanwhile the investigators aim to testify the effects of immunosuppressant in preventing IgG4-RD relapse. This study is a prospective cohort clinical trial.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.
