Systemic lupus erythematosus

Overview

Board takeaway: Review active organ disease, immune suppression, cytopenias, and antithrombotic treatment before invasive dental care.

What is systemic lupus erythematosus?

Systemic lupus erythematosus (SLE) is a relapsing autoimmune disease affecting multiple organs. Childhood-onset disease can be substantial. Fever, fatigue, weight loss, arthritis, photosensitivity, malar or discoid rash, and oral or nasal ulcers may occur; no single finding defines the whole disease.

Which systemic features of lupus change dental risk?

• Blood: anemia, leukopenia, or thrombocytopenia can alter infection and bleeding risk.
• Kidneys: nephritis, hypertension, and impaired renal function affect drug selection and dosing.
• Heart and vessels: pericarditis, valvular disease, or thrombosis may require specific assessment.
• Neurology: seizures or neuropsychiatric disease can affect communication and emergency planning.
• Treatment: immune suppression, glucocorticoid exposure, and prescribed anticoagulants require review.

What oral findings can occur in lupus?

Often painless palatal ulcers, buccal or tongue lesions, discoid changes, aphthous ulcers, and cheilitis may occur. Secondary salivary dysfunction can produce dry mouth, burning, and increased caries risk. Persistent or atypical lesions require evaluation for infection and other diagnoses; not every ulcer is a flare.

How should dental treatment be planned for lupus?

Assess disease activity and consult rheumatology for relevant organ involvement or invasive procedures. Obtain clinically indicated blood counts and a bleeding plan. Coordinate renal dosing, immune suppression, and any established adrenal-insufficiency plan. Use gentle hygiene and fluoride prevention; address oral discomfort so brushing and nutrition remain feasible. Significant systemic illness may require deferral of elective care.

Does lupus require endocarditis prophylaxis or special light precautions?

Lupus or Libman–Sacks valvulitis alone does not automatically meet cardiac endocarditis-prophylaxis criteria. Determine any qualifying valve prosthesis, prior infective endocarditis, or other indication; immune-risk decisions are individualized with the medical team. For documented photosensitivity, avoid relevant ultraviolet exposure and discuss needed accommodations rather than assuming ordinary dental lighting triggers every patient.

What treatment and prognosis apply to lupus?

Therapy is chosen for disease activity and organs involved, often including hydroxychloroquine, glucocorticoids, and steroid-sparing agents. Long-term outcomes depend on renal, vascular, neurologic, and treatment-related complications. Stable disease permits care with an appropriate individualized plan.
