Why is my daughter’s, 26, dermatitis worsening in pregnancy?

Hello,

Welcome to icliniq.com.

I can understand your concern.

This is a tough situation because pregnancy itself can worsen atopic dermatitis in some women and limit what medicines can be safely used. From what you describe, widespread eczema, bleeding from scratching, loss of sleep, facial swelling – it is clearly severe and affecting her quality of life, plus stress is pushing her blood pressure up, which is another concern in pregnancy. Hydrocortisone alone is too weak for such extensive flare-ups.

The probable cause is that underlying chronic atopic dermatitis flared up during pregnancy due to immune-hormonal changes.

Investigations to be done are as follows:

• Blood pressure monitoring closely (since stress plus pregnancy leads to risk of preeclampsia).

• Dermatology input for severity scoring.

• CBC (complete blood count), liver/kidney tests if systemic treatment is considered.

Differential diagnosis is as follows:

• Polymorphic eruption of pregnancy (less likely with her long history).

• Allergic contact dermatitis.

• Psoriasis flare.

The probable diagnosis is a severe atopic dermatitis flare in pregnancy.

The treatment plan is as follows:

• Topical steroids: Medium-potency steroids in limited courses are considered safe in pregnancy, especially if applied in a thin layer and not over a large body area. Hydrocortisone may be insufficient; OB and dermatologist can agree on moderate-potency ones (like mometasone) for short bursts.

• Moisturizers: thick emollients (petrolatum, paraffin-based) multiple times a day, fragrance-free only.

• Antihistamines: certain non-sedating antihistamines (like Loratadine, Cetirizine) are considered safe in pregnancy and may reduce itch. Sedating ones (like Chlorpheniramine) can sometimes help at night for sleep.

• UVB (ultra-violet) phototherapy is actually safe in pregnancy and effective for severe eczema – worth discussing if available.

• Tacrolimus/Pimecrolimus: limited data in pregnancy, generally avoided unless very localized and resistant, but not first line.

• Oral steroids: short course in extreme flare may be used if benefit outweighs risk, but always under obstetrician supervision.

• Stress/mental health: counseling, relaxation, support, since itching plus appearance is causing distress.

I would recommend she see her OB and dermatologist together, a combination approach. Please update if her BP (blood pressure) is persistently high, since eczema stress plus pregnancy hypertension risk needs close monitoring. If her skin is worsening despite topical measures, narrowband UVB therapy could be a safe next step.

Preventive measures are as follows:

Avoid hot showers, stick to lukewarm water, pat dry (not rub), and apply emollient right after bathing. Cotton clothing only. Avoid strong detergents, fragrances, and known personal triggers. Sleep hygiene to reduce the itching cycle at night.

I hope this helps.

Kindly follow up if you have more concerns.

Thank you.
