How can I manage atopic dermatitis and hypothyroidism at 34?

Question

Hello doctor,

I am 34 years old and have had atopic dermatitis since I was a teenager, but over the past year, it has become completely uncontrollable. I work in healthcare, and the constant hand washing and glove use have caused my hands to crack and bleed during every shift.

My dermatologist started me on Dupilumab injections four months ago. Although there has been some improvement, the involvement of my hands is still very severe. My SCORAD index was 58 at my last assessment, which my doctor said falls within the severe range.

I was also recently diagnosed with hypothyroidism, and my TSH level is 8.9. My endocrinologist believes the thyroid issue may be worsening my skin condition.

The problem is that the hospital is now questioning my fitness for clinical duties because of the infection risk from the cracks and wounds on my hands.

I also have not slept properly for weeks because of severe itching at night. I am wondering whether atopic dermatitis can become this resistant to biologic therapy and whether there is anything else I could try alongside the injections.

Additionally, I have developed symptoms of conjunctivitis, which my optometrist believes may be related to the atopic dermatitis.

Please help.

Thank you.

Hello,

Welcome to icliniq.com.

Thank you so much for sharing your concern with me.

Based on your description, you appear to have severe, chronic atopic dermatitis with significant occupational hand involvement, which is unfortunately common among healthcare workers due to frequent hand washing, disinfectant exposure, and prolonged glove use.

A SCORAD (SCORing Atopic Dermatitis) score of 58 falls within the severe disease range, and persistent symptoms despite biologic therapy can occur in a subset of patients. Dupilumab is currently one of the most effective biologic treatments for moderate-to-severe atopic dermatitis, but improvement may continue gradually over six to 12 months, and some patients experience only a partial response, particularly in the hands and feet, which tend to be more treatment-resistant areas.

Because of this, additional therapies are often used alongside biologics, and persistent hand eczema after four months does not necessarily indicate treatment failure. In your situation, repeated hand hygiene and glove occlusion may also be causing irritant contact dermatitis on top of atopic dermatitis, which can worsen fissuring and bleeding.

Helpful measures may include using alcohol-based hand rubs instead of soap when appropriate to reduce barrier damage, applying thick fragrance-free emollients immediately after hand hygiene, wearing cotton glove liners under nitrile gloves to reduce sweat and irritation, applying barrier repair creams containing ceramides several times daily, and using petrolatum-based ointments overnight with cotton gloves.

For persistent hand involvement despite Dupilumab, dermatologists may consider short courses of high-potency topical corticosteroids during flares, topical calcineurin inhibitors such as Tacrolimus for maintenance therapy, topical JAK (Janus Kinase) inhibitors like Ruxolitinib where available, wet-wrap therapy during severe flares, or narrowband UVB (ultraviolet B) phototherapy in refractory cases.

In certain resistant situations, systemic treatments such as Upadacitinib or Abrocitinib may be considered if biologic therapy does not achieve adequate control, though this decision must be individualized by your dermatologist.

Your recently diagnosed hypothyroidism may also be contributing, as uncontrolled hypothyroidism can cause significant skin dryness and impaired barrier function, potentially aggravating eczema; optimizing thyroid hormone replacement with your endocrinologist may therefore help improve skin hydration and recovery.

The conjunctivitis symptoms you described are also notable, as eye inflammation can occur in people with atopic disease and is a recognized side effect of Dupilumab; evaluation by an ophthalmologist is recommended, as treatment may include lubricating drops or anti-inflammatory therapy depending on severity.

Cracked hands can increase the risk of secondary bacterial infection, particularly with Staphylococcus aureus, so if fissures are severe, temporary modified duties or reduced wet-work exposure may help the skin barrier heal.

Because you are also experiencing significant nighttime itching and sleep disruption, your physician may consider options such as sedating antihistamines at night, intensive moisturization before sleep, and short-term anti-inflammatory therapy during active flares.

It would be important to follow up with your dermatologist if the hand fissures remain severe after about six months of Dupilumab therapy, if you develop signs of infection such as pus, warmth, or increasing pain, if the eye symptoms worsen, or if occupational exposures continue to significantly aggravate your condition.

I hope this helps you.

Thank you.
