Systemic Lupus Erythematosus: Primary Care Approach to Diagnosis and Management

Area of Science:

• Immunology
• Rheumatology
• Internal Medicine

Background:

• Systemic lupus erythematosus (SLE) is a chronic autoimmune disease with diverse systemic manifestations.
• Family physicians play a vital role in the early detection, management, and monitoring of SLE patients.
• Understanding SLE's broad impact on skin, joints, kidneys, and other organs is essential for primary care.

Purpose of the Study:

• To outline the role of family physicians in managing systemic lupus erythematosus.
• To emphasize the importance of early diagnosis and appropriate patient referral.
• To highlight key diagnostic criteria and cornerstone treatments for SLE.

Main Methods:

• Review of the American College of Rheumatology's 11 classification criteria for SLE diagnosis.
• Discussion of diagnostic specificity (95%) and sensitivity (85%) with ≥4 criteria met.
• Outline of treatment strategies including hydroxychloroquine, glucocorticoids, and immunosuppressants based on disease severity.

Main Results:

• Meeting ≥4 of the 11 ACR criteria allows for SLE diagnosis with high specificity and sensitivity.
• Hydroxychloroquine is foundational for reducing SLE flares and constitutional symptoms.
• Low-dose glucocorticoids manage most SLE manifestations, while immunosuppressants are reserved for severe cases.

Conclusions:

• Family physicians should be adept at recognizing SLE manifestations for timely diagnosis and management.
• Patients with mild SLE can be managed in primary care, while severe or complicated cases require rheumatologist referral.
• Collaborative care between family physicians and rheumatologists is paramount for optimal chronic disease management and preventive health in SLE patients.
