Systemic Lupus Erythematosus: What Every Clinician Needs to Know

Area of Science:

• Rheumatology and Immunology
• Autoimmune Diseases
• Systemic Lupus Erythematosus (SLE) Pathobiology

Background:

• SLE disproportionately affects women of reproductive age, causing significant morbidity and mortality.
• Despite advances, SLE patients face risks of kidney failure, cardiovascular disease, infection, and pregnancy complications.
• Primary care clinicians are crucial for early SLE recognition, evaluation, and comorbidity management.

Purpose of the Study:

• To link SLE pathobiology to current therapies and outline a practical diagnostic and management approach.
• To emphasize a treat-to-target strategy for low disease activity or remission with minimal glucocorticoid use.
• To guide clinicians in managing SLE manifestations, comorbidities, and reproductive health.

Main Methods:

• Comprehensive literature review linking SLE pathobiology (immune tolerance loss, immune complex injury, type I interferon) to therapies.
• Outlined a diagnostic approach focusing on pattern recognition, antinuclear antibody testing, and rheumatology referral.
• Organ-based sections detail screening, direct management, and urgent referral for SLE manifestations and comorbidities.

Main Results:

• Highlights the distinction between SLE disease activity and cumulative damage.
• Advocates for hydroxychloroquine as foundation therapy and a glucocorticoid-sparing approach.
• Emphasizes aggressive prevention of cardiovascular and bone disease in SLE patients.

Conclusions:

• Structured collaboration between rheumatology and non-rheumatology clinicians is vital for improving SLE outcomes.
• A treat-to-target strategy focused on remission and minimal glucocorticoid exposure is recommended.
• Comprehensive management including comorbidity control and reproductive health is essential for SLE patients.
