Systemic Lupus Erythematosus (SLE)

Condition: Systemic Lupus Erythematosus (SLE)

 

Brief Overview: Systemic lupus erythematosus is a chronic autoimmune disease that can affect multiple organ systems, including the skin, joints, kidneys, brain, heart, and lungs. It is characterized by periods of remission and flare-ups, with a wide range of clinical manifestations.

 

Prevalence: SLE affects approximately 20-150 per 100,000 individuals, with a higher prevalence in women of childbearing age and certain ethnic groups, such as African Americans, Hispanics, and Asians.

 

Etiology: The exact cause is unknown but involves genetic, hormonal, and environmental factors that trigger an abnormal immune response, leading to widespread inflammation and tissue damage.

 

Risk Factors:
•    Female sex (9:1 female-to-male ratio)
•    Age (commonly diagnosed between 15-45 years)
•    Genetic predisposition (e.g., HLA-DR2, HLA-DR3)
•    Environmental triggers (e.g., UV light, infections, certain medications)
•    Hormonal influences (e.g., estrogen)

 

Commonly Associated Conditions:
•    Antiphospholipid syndrome
•    Rheumatoid arthritis
•    Sjögren’s syndrome
•    Raynaud’s phenomenon
•    Cardiovascular disease

 

Common Medications:
•    Nonsteroidal anti-inflammatory drugs (NSAIDs) for mild symptoms
•    Corticosteroids for controlling flares
•    Hydroxychloroquine (a disease-modifying antirheumatic drug)
•    Immunosuppressants (e.g., azathioprine, methotrexate, mycophenolate mofetil)
•    Biologic agents (e.g., belimumab)

 

Common Labs, Imaging, and Tests:
•    Antinuclear antibody (ANA) test (most sensitive test for SLE)
•    Anti-dsDNA and anti-Smith antibodies (specific for SLE)
•    Complement levels (C3, C4) to monitor disease activity
•    Urinalysis to detect proteinuria or hematuria (kidney involvement)
•    Imaging (e.g., chest X-ray, echocardiography) for organ involvement

 

Common Symptoms:
•    Fatigue
•    Joint pain and swelling
•    Skin rashes, including the characteristic butterfly rash (malar rash)
•    Photosensitivity
•    Fever
•    Oral or nasal ulcers
•    Hair loss (alopecia)
•    Raynaud’s phenomenon

 

Common Treatments:
•    Hydroxychloroquine to manage symptoms and reduce flares
•    Corticosteroids for acute inflammation
•    Immunosuppressants for severe or refractory cases
•    Lifestyle modifications (e.g., sun protection)

 

Physical Findings:
•    Malar rash (erythematous rash on the cheeks and nose)
•    Discoid lesions
•    Joint tenderness or swelling (non-erosive arthritis)
•    Pericardial or pleural rubs in cases of serositis
•    Edema in nephritis

 

Potential Complications and Contraindications:
•    Lupus nephritis leading to renal failure
•    Cardiovascular disease (e.g., pericarditis, myocarditis)
•    Neurological involvement (e.g., seizures, psychosis)
•    Contraindications for immunosuppressants in active infections

 

General Health and Lifestyle Guidance:
•    Avoid excessive sun exposure and use broad-spectrum sunscreen
•    Maintain a healthy diet and exercise regularly to reduce cardiovascular risk
•    Adhere to prescribed medications and attend regular follow-ups
•    Monitor for signs of organ involvement or new symptoms

 

Suggested Questions to Ask Patients:
•    Have you noticed any patterns or triggers for your symptoms?
•    Do you experience unusual sensitivity to sunlight?
•    Have you had any symptoms such as chest pain, shortness of breath, or blood in your urine?

 

Suggested Talking Points:
•    Explain the chronic nature of lupus and the importance of monitoring for flares.
•    Emphasize that effective treatments can manage symptoms and improve quality of life.
•    Discuss the need for routine lab tests to monitor disease activity and organ function.
•    Reassure patients that with proper care, complications can be minimized.
•    Eat a whole foods diet. Make sure to eat foods high in omega 3 such as wild caught salmon. Add turmeric to foods.
