Precautions for Systemic Lupus Erythematosus (SLE)


Hello, doctor.
I would like to ask if the coin-shaped erythematous lesions of lupus on the skin will improve after taking quinine.
Additionally, should sunscreen be applied during winter and at night, and is it necessary to apply it when wearing long-sleeved clothing? Are there any dietary restrictions I should be aware of? Thank you.

Subacute Cutaneous Lupus Erythematosus (SCLE) is commonly seen in young women and can be triggered by sun exposure.
Approximately half of the patients may develop Systemic Lupus Erythematosus (SLE).
Diagnosis is primarily based on medical history and immunopathological skin biopsy results.
Treatment options include oral Hydroxychloroquine and topical corticosteroid ointments.
Improvement is typically observed after four months of treatment, while complete resolution varies from person to person.
Sunscreens cannot completely block sun exposure, so it is advisable to avoid direct sunlight.
Regarding dietary recommendations, there is currently no definitive conclusion or suggestion from the medical community.
A small number of physicians may recommend certain special diets, but these are considered adjuvant therapies, and it is important to continue taking prescribed medications regularly.

Discoid lupus erythematosus (DLE) is a chronic skin condition characterized by coin-shaped lesions that can appear on various parts of the body, particularly on sun-exposed areas. Managing DLE effectively requires a multifaceted approach, including medication, lifestyle modifications, and dietary considerations. Here are some essential tips for managing discoid lupus erythematosus:

1. Medication Management
The primary treatment for DLE often includes topical corticosteroids and antimalarial medications such as hydroxychloroquine (Plaquenil). Hydroxychloroquine is known to help reduce inflammation and prevent flare-ups. While some patients may experience improvement in their lesions within a few months, complete resolution can vary from person to person. It is crucial to adhere to the prescribed treatment regimen and maintain regular follow-ups with your healthcare provider to monitor the condition and adjust medications as necessary.


2. Sun Protection
Sun exposure can exacerbate DLE symptoms, making sun protection a critical component of management. Patients should apply a broad-spectrum sunscreen with an SPF of at least 30 daily, even in winter or on cloudy days. This includes applying sunscreen during the evening if you plan to be outdoors. Additionally, wearing protective clothing, such as long sleeves and wide-brimmed hats, can help shield the skin from harmful UV rays. Remember that even when wearing long sleeves, sunscreen should still be applied to exposed areas of skin.


3. Lifestyle Modifications
Maintaining a healthy lifestyle can significantly impact the management of DLE. This includes:
- Stress Management: Stress can trigger flare-ups, so incorporating stress-reducing activities such as yoga, meditation, or regular exercise can be beneficial.

- Regular Sleep Patterns: Aim for a consistent sleep schedule to help your body recover and manage inflammation.

- Avoiding Known Triggers: Identify and avoid any specific triggers that may worsen your condition, such as certain medications or environmental factors.


4. Dietary Considerations
While there is no specific diet proven to cure DLE, a balanced diet can support overall health and potentially reduce inflammation. Consider the following dietary tips:
- Anti-inflammatory Foods: Incorporate foods rich in omega-3 fatty acids (like fish, flaxseeds, and walnuts), fruits, vegetables, and whole grains. These foods may help reduce inflammation in the body.

- Hydration: Staying well-hydrated is essential for skin health. Aim to drink plenty of water throughout the day.

- Limit Processed Foods: Reducing the intake of processed foods, sugars, and trans fats may help manage inflammation and improve overall health.


5. Regular Monitoring and Follow-up
Regular check-ups with a dermatologist or rheumatologist are essential for monitoring the progression of DLE and adjusting treatment as needed. Blood tests may be conducted to assess for any systemic involvement or to monitor the effects of medications.


6. Educate Yourself
Understanding your condition can empower you to manage it more effectively. Stay informed about DLE, its symptoms, and treatment options. Joining support groups or forums can also provide valuable insights and emotional support from others experiencing similar challenges.

In conclusion, managing discoid lupus erythematosus involves a combination of medication, sun protection, lifestyle changes, and dietary considerations. By actively participating in your treatment plan and making informed choices, you can effectively manage your condition and improve your quality of life. Always consult with your healthcare provider before making any significant changes to your treatment or lifestyle.
