Psoriasis, a chronic inflammatory skin condition, can present unique challenges during pregnancy. Managing psoriasis while ensuring the safety of both mother and fetus requires careful consideration and a tailored approach. This article explores the impact of pregnancy on psoriasis and discusses safe treatment options for expectant mothers.

Impact of Pregnancy on Psoriasis

Pregnancy can have varying effects on psoriasis symptoms. While some women experience improvement in their condition , others may see their symptoms worsen or remain unchanged. The hormonal changes during pregnancy can influence the immune system , potentially affecting psoriasis severity.

Potential Improvements

Approximately 40-60% of women report improvement in their psoriasis during pregnancy. This improvement is often attributed to the increase in estrogen and progesterone levels, which can have anti-inflammatory effects.

Possible Exacerbations

For some women, pregnancy may trigger psoriasis flares or worsen existing symptoms. This can be due to hormonal fluctuations, stress, or changes in treatment regimens. It's important to note that postpartum flares are common, affecting up to 65% of women with psoriasis.

Considerations for Psoriasis Management During Pregnancy

Managing psoriasis during pregnancy requires balancing the need for symptom control with the safety of the developing fetus. Several factors should be considered:

1. Disease Severity : The extent and severity of psoriasis will influence treatment decisions.
2. Trimester : Some treatments may be safer in certain trimesters than others.
3. Previous Treatment Response : Understanding which treatments have been effective in the past can guide decision-making.
4. Potential Risks : All treatments should be evaluated for their potential risks to the fetus.

Safe Treatment Options

Topical Treatments

Topical treatments are generally considered the safest option for managing psoriasis during pregnancy. These include:

• Emollients : Moisturizers are safe and can help manage mild symptoms.
• Low to Moderate Potency Corticosteroids : These can be used in limited amounts under medical supervision.
• Calcipotriene : A vitamin D analog that may be used cautiously in small amounts.

Phototherapy

Narrowband UVB phototherapy is considered safe during pregnancy and can be an effective option for managing moderate to severe psoriasis.

Systemic Treatments

Most systemic treatments are avoided during pregnancy due to potential risks to the fetus. However, in severe cases where the benefits outweigh the risks, certain options may be considered:

• Cyclosporine : May be used in severe cases under close medical supervision.
• Biologics : Limited data is available, but some biologics may be considered in specific situations.

Treatments to Avoid

Certain psoriasis treatments should be avoided during pregnancy due to known risks:

• Methotrexate : This medication is contraindicated during pregnancy and should be discontinued at least three months before conception.
• Retinoids : Both oral and topical retinoids are teratogenic and must be avoided.
• PUVA : Psoralen plus UVA therapy is not recommended due to potential risks.

Preconception Planning

For women with psoriasis planning to become pregnant, preconception planning is crucial. This may involve:

1. Discussing treatment options with healthcare providers
2. Transitioning to pregnancy-safe treatments
3. Optimizing psoriasis control before conception

Postpartum Considerations

After delivery, many women experience psoriasis flares. Treatment options may need to be reevaluated, especially for women who plan to breastfeed. Some treatments that were avoided during pregnancy may be reintroduced postpartum.

Conclusion

Managing psoriasis during pregnancy requires a careful balance between controlling symptoms and ensuring fetal safety. A personalized approach, developed in consultation with healthcare providers, is essential. By understanding the available options and potential risks, expectant mothers with psoriasis can make informed decisions about their treatment plan.
