Systemic Lupus Erythematosus
Conditions
Brief summary
The study aims to explore the therapeutic value and mechanism of Interleukin-2 on children with rheumatic diseases (Systemic Lupus Erythematosus, Primary Sjögren Syndrome, Juvenile Idiopathic Arthritis).
Detailed description
The investigators designed a single center, open-label, prospective study that routinely administered low-dose IL-2 therapy to monitor the improvement of clinical and laboratory parameters to explore its efficacy and to observe changes in immune cell subsets and cytokines. Methods: Patients were divided into two groups. One received standard therapy, while another one administrate with low-does IL-2 plus standard therapy.
Interventions
DRUGIL-2
Patients were received low dose recombinant human Interleukin-2

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change in steroid dose and immunosuppressor dose at 1 year compared to control group | 1 year | The average daily doses of steroid and immunosuppressor per square meter was recorded |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| The Immunologic Impact of IL-2 Treatment | 1 month,3 month,6 month,1 year | Laboratory measures were detected, including, C3, C4 and anti-dsDNA titres. |
| Immunological Responses | 1 month,3 month,6 month,1 year | Enumeration of the number of subjects with a change in the absolute number of immune cells and serum cytokines in the peripheral blood |
| Change from baseline in SELENA SLEDAI Score | 1 month,3 month,6 month,1 year | Assessment version of the SLE Disease Activity Index (SELENA-SLEDAI) change. The higher the score represent the worse of the disease. The total score ranges from 0 to 105 points. |
| Change from baseline in EULAR SS disease activity index | 1 month,3 month,6 month,1 year | Low-activity (ESSDAI\<5),moderate-activity (5≤ESSDAI≤13) ,high-activity (ESSDAI≥14) levels. |
| Incidence of adverse drug reactions | up to 1 year | Adverse events includes injection site reactions, influenza-like symptoms, infection, fever, tumor, cardiovascular event，drug-induced liver and kidney damage. |
