Psoriasis is a chronic autoimmune-related skin disease. Its treatment goals are to relieve symptoms, control inflammatory responses, prevent the spread of skin lesions, and improve patients' quality of life. Treatment strategies should be individualized based on the patient's age, disease stage, severity of symptoms, and comorbidities.
Modern medicine has developed various treatment approaches, including topical medications, oral drugs, biologics, and phototherapy. Treatment plans often adopt a stepwise strategy, starting with local therapy and escalating treatment intensity if the initial response is inadequate. Regular assessment of efficacy and monitoring for potential side effects are necessary throughout the treatment process to ensure safety and effectiveness.
Options for psoriasis treatment can be divided into three main categories: topical therapy, systemic therapy, and phototherapy, as detailed below:
Topical drugs are fundamental in psoriasis treatment, commonly including:
When topical treatments are insufficient, physicians may prescribe oral drugs:
This class of drugs targets specific immune mediators, suitable for moderate to severe patients:
Narrowband UVB therapy suppresses epidermal hyperproliferation using specific wavelengths of ultraviolet light, typically requiring 2-3 sessions per week. The 308 nm monochromatic laser targets localized lesions, suitable for scalp or extremity involvement. PUVA therapy combines oral or topical photosensitizers with UVA exposure but requires caution due to potential increased skin cancer risk with long-term use.
Localized occlusion therapy can enhance drug absorption, and hydrogen sulfide mineral water in hot springs may provide relief for some patients. Traditional Chinese medicine formulations for clearing heat and detoxification may assist symptom relief but should be used under medical supervision to avoid drug interactions.
Lifestyle modifications are crucial for controlling the disease:
Dietary adjustments are not primary treatments but a low-inflammatory diet (such as the Mediterranean diet) may help reduce systemic inflammation. Monitoring vitamin D intake is also important, as excessive supplementation could affect metabolic balance.
Current research focuses on precision medicine and new targets:
Minimally invasive methods such as transdermal electrical stimulation and stem cell therapy are still in clinical trials and may become new options in the future. Research on immune checkpoint modulators also shows potential applications.
Inhibitors targeting the IL-17/IL-22 axis are in phase III clinical trials, expected to improve efficacy and reduce drug resistance. Epigenetic regulation techniques may restore abnormal DNA methylation, fundamentally modulating inflammatory responses.
The following situations warrant immediate medical consultation:
If there is no improvement after two weeks of self-treatment or signs of skin infection (such as ulceration or pus), seek evaluation by a dermatologist immediately. Severe cases (such as erythrodermic or arthropathic psoriasis) must be managed by a specialized team. Regular follow-up examinations, including liver and kidney function tests and hematological monitoring, are essential to ensure treatment safety. Patient education programs can improve adherence, and joining support groups may provide psychological support.
When choosing a treatment plan, it is important to balance efficacy and side effects. Biologics may require regular blood monitoring, while topical ointments should be used cautiously to avoid skin irritation. Regular follow-up with your doctor to assess disease progression and adjusting the plan based on symptom severity and lifestyle is recommended. Discussing the safety of long-term medication use is also essential.
What specific benefits does daily moisturizing provide in alleviating psoriasis symptoms?Moisturizing enhances skin barrier function, reducing scaling and itching. Use fragrance-free, low-irritant lotions or ointments, applying within 3 minutes after bathing for best results. For severely cracked areas, medicated creams can be used, but follow medical advice to avoid overuse of corticosteroids.
Can dietary adjustments truly improve the frequency of psoriasis flare-ups?While no specific "psoriasis diet" has been proven to cure the condition, anti-inflammatory diets (such as the Mediterranean diet) may reduce inflammatory responses. Some patients find that dairy products or alcohol can trigger flare-ups, but individual responses vary. Keeping a food diary and consulting with a nutritionist can help tailor dietary changes.
Why do psoriasis symptoms often worsen in winter, and how should this be managed?Dry air and lack of sunlight can exacerbate skin cracking and inflammation. During winter, using humidifiers to maintain humidity at 40-60%, supplementing UVB phototherapy, and strengthening skin hydration after cleansing are recommended. If symptoms suddenly worsen, seek medical attention promptly and avoid increasing medication doses without consultation.
Are natural therapies such as herbal medicine or fish oil supplements effective for treatment?Some studies suggest that omega-3 fish oil may help reduce inflammation, but effects vary among individuals and high doses (about 3-6 grams/day) are often required. Herbal remedies should be used cautiously, as some ingredients may interact with Western medications. It is advisable to try alternative therapies under medical supervision to avoid delays in standard treatment that could worsen symptoms.
