What history needs to be extracted in a patient with Systemic Lupus Erythematosus (SLE), considering demographics, symptoms, past medical history, and previous treatments?

• Antinuclear antibody (ANA): Titer and pattern 2, 5.

Complement Levels

• C3 and C4: Document previous low levels indicating active disease 1.

Routine Laboratory Abnormalities

• Anemia: Hemoglobin levels and type (hemolytic vs. chronic disease) 1.
• Thrombocytopenia: Platelet counts 1.
• Leukopenia: White blood cell counts 2.
• Elevated creatinine: Renal function trends 1.
• Proteinuria: Quantification (24-hour urine or spot protein/creatinine ratio) 1.

Treatment History

Current and Past Medications

• Antimalarials: Hydroxychloroquine or chloroquine dosage and duration 1, 6.

• Remission periods: Duration and maintenance therapy 2.
• Drug toxicity: Specific adverse effects from each medication 3.
• Ophthalmologic screening: Retinal examination results for hydroxychloroquine toxicity 6.

Cardiovascular Risk Factor Assessment
