What is the recommended treatment for severe hand dermatitis?

Treatment of Severe Hand Dermatitis

For severe hand dermatitis, escalate immediately to clobetasol propionate 0.05% (super-high-potency topical corticosteroid) applied twice daily for up to 2 consecutive weeks, combined with aggressive moisturization using the "soak and smear" technique nightly. 1, 2

Immediate Pharmacologic Management

High-Potency Topical Corticosteroids

• Apply clobetasol propionate 0.05% cream, ointment, or gel twice daily to affected areas for severe hand dermatitis that has failed lower-potency steroids 1, 2
• Limit treatment to 2 consecutive weeks maximum and do not exceed 50g per week, as this is a super-high-potency corticosteroid 2
• If no improvement occurs within 2 weeks, reassess the diagnosis and consider alternative etiologies 2
• Do not use occlusive dressings with clobetasol 2

Critical Adjunctive Moisturization Protocol

• Implement the "soak and smear" technique nightly: soak hands in plain lukewarm water for 20 minutes, immediately apply moisturizer to damp skin, then apply topical steroid to affected areas 1
• Apply moisturizer immediately after every hand washing using two fingertip units for adequate coverage 3, 1
• Continue this regimen for up to 2 weeks 3

Mandatory Trigger Identification and Avoidance

Eliminate Irritants

• Avoid hot water, dish detergents, frequent hand washing with harsh soaps, and disinfectant wipes 1
• Use lukewarm or cool water only for hand washing 3
• Pat hands dry gently rather than rubbing 3

Allergen Assessment

• Refer to dermatology for patch testing if allergic contact dermatitis is suspected, as this fundamentally changes management 3, 1
• For glove-related allergic contact dermatitis, switch to accelerator-free gloves (neoprene or nitrile) 3, 1

Second-Line Therapies for Recalcitrant Cases

When to Escalate Beyond Topical Steroids

• Consider advanced treatment when hand dermatitis does not improve after 6 weeks of appropriate treatment 3, 1
• Recalcitrant cases require escalation to phototherapy or systemic agents 3

Phototherapy Options

• PUVA or narrow-band UVB phototherapy should be considered for cases failing topical corticosteroids 1, 4
• Local PUVA may lead to improvement compared to narrow-band UVB, though adverse events (mainly erythema) occur more frequently with UVB 4

Systemic Immunosuppressive Therapy

• Oral cyclosporin 3 mg/kg/day probably improves both investigator-rated and participant-rated symptom control compared to topical betamethasone after 6 weeks 4
• Monitor for adverse events including dizziness, which occurs in approximately 68% of patients on cyclosporin 4

Oral Retinoid Therapy

• Alitretinoin 30 mg daily is highly effective for severe chronic hand eczema, with a number needed to treat of 4 for investigator-rated symptom control 4
• Alitretinoin 10 mg daily is also effective but less so than the 30 mg dose (NNTB 11 versus 4) 4
• Headache is a common adverse event, particularly with the 30 mg dose 4
• Assess outcomes between 48-72 weeks of treatment 4

Critical Monitoring and Safety Considerations

Corticosteroid-Related Precautions

• Monitor for skin atrophy, striae, or secondary infection during high-potency topical steroid treatment 1
• High-potency steroids should be limited to 12 weeks maximum; super-high-potency steroids (like clobetasol) should be limited to 2-3 weeks 1, 2
• Never apply high-potency topical steroids to the face, groin, axillae, or genital regions due to increased absorption and atrophy risk 1
• Prolonged topical steroid use can paradoxically damage the skin barrier 3

Occupational Modifications

• For healthcare workers, use water-based moisturizers under gloves (oil-based products break down latex and rubber) 3, 1
• Latex, vinyl, and nitrile gloves resist breakdown from ethanol or isopropyl alcohol 3
• Never apply gloves when hands are still wet from hand washing or sanitizer 3, 1

Common Pitfalls to Avoid

• Do not use very hot water for hand washing, as this damages the skin barrier 1
• Do not make unsupervised repeat prescriptions of potent topical corticosteroids without regular clinical review 1
• Do not use superglue to seal inflammatory or healing fissures 3
• Do not increase duration of glove occlusion without underlying moisturizer application 3

Mandatory Dermatology Referral Criteria

• Suspected allergic contact dermatitis requiring patch testing 3, 1
• No improvement after 6 weeks of appropriate first-line treatment 1
• Change in baseline hand dermatitis pattern or severity 3, 1
• Need for systemic therapy consideration 3
