Objective: To review the complex interactions and processes in systemic lupus erythematosus (SLE).

Data Sources: Brief review of the important literature in peer-reviewed journals.

Study Selection: Studies on the clinical and immunologic features, pathogenesis, epidemiology, laboratory evaluation, and treatment of SLE are included in this review.

Results: SLE may include a variety of disease entities, such as isolated cutaneous lupus, undifferentiated connective tissue disease, mixed connective tissue disease, and drug-induced lupus. There are many ongoing clinical trials in SLE patients of therapeutics with different mechanisms of cellular action, such as classic immunosuppression, cell depletion, antigen-specific immunomodulation, and targeting of antigen-nonspecific, immune-activating molecules. New immune cell-targeted therapies are now available that are specifically designed to block cellular pathways involved in disease pathogenesis.

Conclusion: The practicing physician should understand the immunology, pathogenesis, laboratory evaluation, and updated treatment options when diagnosing SLE in their clinic or daily practice.

Fatigue is prevalent in immune-mediated inflammatory and neurodegenerative diseases, yet its assessment relies largely on patient-reported outcomes, which capture perception but not fluctuations over time. Wearable sensors, like inertial measurement units (IMUs), offer a way to monitor daily activities and evaluate functional capacity. This study investigates the relationship between sit-to-stand and stand-to-sit transitions and self-reported physical and mental fatigue in participants with Parkinson's, Huntington's, rheumatoid arthritis, systemic lupus erythematosus, primary Sjögren's syndrome and inflammatory bowel disease.

Objective: Glucocorticoid (GC) tapering and withdrawal to reduce damage represents a key aspect of the European Alliance of Associations for Rheumatology (EULAR) SLE recommendations. However, optimal strategies for relapse-free GC cessation remain ill-defined. We characterised clinical predictors and their combined effect on flares in patients with SLE who discontinued GC.

Objective: Traditional initial treatment regimens for lupus nephritis (LN) used oral glucocorticoids (GC) in starting doses up to 1.0 mg/kg/day prednisone equivalent with or without a preceding intravenous methylprednisolone pulse. More recent management guidelines recommend lower starting oral GC doses following intravenous pulse therapy.

Objective: Both belimumab and telitacicept are recognised blockers for B lymphocyte activation, both of which have been approved as add-on therapies for SLE in China. The aim of this study is to compare the efficacy of rituximab (RTX) followed by belimumab or telitacicept in a real-world cohort.

Methods: A total of 49 refractory lupus nephritis patients were enrolled from four independent centres, subsequently categorised into two treatment groups: belimumab group (n=35) and telitacicept group (n=14) based on their treatment following RTX.

Dose effect of corticosteroids on peripheral lymphocyte profiles in patients with systemic lupus erythematosus.

Clin Rheumatol

January 2025

Department of Rheumatology and Immunology, Peking University People's Hospital, 11 Xizhimen South Street, Beijing, 100044, China.

Objective: To investigate the dose effect of methylprednisolone (MP) on peripheral lymphocyte profiles in patients with systemic lupus erythematosus (SLE). This study investigated the impact of varied MP doses on peripheral lymphocyte subtypes in SLE patients.

Methods: We conducted a prospective study involving 51 SLE patients, categorized into four groups (40 mg/day, 80 mg/day, 500 mg/day, and 1000 mg/day) based on the administered MP dosage during hospitalization.
