Eczema And COVID-19: 5 Practical Strategies To Prevent Flares

The COVID-19 pandemic reshaped daily life, profoundly impacting those with chronic skin conditions like eczema, also known as atopic dermatitis (AD). While the virus itself did not drastically alter infection severity in most eczema patients, pandemic measures such as frequent handwashing, mask-wearing, and stress triggered widespread skin flare-ups. This article delves into research-backed findings on how COVID-19 intersected with eczema, offering practical strategies for management and prevention.

Understanding Eczema in the Pandemic Context

Eczema involves an overactive immune response leading to inflamed, itchy skin, distinct from a compromised immune system. Studies confirm that individuals with eczema face no elevated risk of severe COVID-19 outcomes compared to the general population, as their immunity is hyperactive rather than deficient. However, real-world data from large cohorts revealed higher odds of contracting the virus among eczema patients (odds ratio 1.532), possibly due to behavioral or environmental factors.

During lockdowns, mixed effects emerged: some patients reported better control from reduced exposure to triggers like allergens and sweat, enhanced skincare routines, and treatment adherence. Continuation of biologics like dupilumab correlated with disease improvement in adolescents and adults. Conversely, disruptions in healthcare access led to flares in others, particularly those discontinuing therapies.

Skin Flares Triggered by Pandemic Habits

Frequent handwashing and sanitizer use damaged the skin barrier, exacerbating eczema. Research showed increased transepidermal water loss in AD patients after sanitizer exposure, worsening dryness and irritation. Face masks, essential for protection, caused facial flares; daily wear over 6 hours linked to adverse skin reactions in those with preexisting conditions.

• Hand hygiene impact: Soap and sanitizers stripped natural oils, leading to higher flare frequency.
• Mask-related issues: Friction and occlusion promoted perioral dermatitis and eczema worsening.
• Stress and isolation: Psychological strain from lockdowns amplified symptoms via cortisol-driven inflammation.

In Italy, Eczema Area and Severity Index (EASI) scores rose significantly during initial lockdowns, from 2.42 to 5.10 in one month. Hospital admissions for eczema dipped overall due to infection fears, though severity increased among those seeking care.

COVID-19 Infection and Eczema Symptoms

Direct COVID-19 infection rarely worsened eczema severity scores like EASI or SCORAD. However, severe cases with dyspnea saw new skin lesions and itching in up to 36% of patients, potentially from elevated IL-13 levels mirroring eczema pathways. Long-term, post-COVID effects included exacerbations of preexisting eczema alongside urticaria and telogen effluvium.

A retrospective study of over 24,000 AD patients found elevated infection risk, modulated by comorbidities and treatments. Dupilumab users had lower odds than corticosteroid recipients, suggesting biologics may offer protective effects without immunosuppression risks.

Guidelines for Managing Eczema Therapies

Expert bodies like the International Eczema Council advise continuing systemic treatments unless active COVID-19 infection occurs. For immunosuppressed patients, monitor for early symptoms and prioritize emollients post-handwashing to prevent hand eczema. In confirmed cases, temporary dose reductions may be considered, balancing against uncontrolled disease risks like asthma exacerbation.

Key recommendations include:

• Evaluate risks/benefits individually, factoring age and comorbidities.
• Maintain social distancing and hygiene with moisturizer follow-up.
• Avoid abrupt discontinuation of biologics like dupilumab.

Practical Strategies to Minimize Flares

To safeguard skin during respiratory pandemics, adopt these evidence-based habits:

1. Moisturize proactively: Apply fragrance-free emollients immediately after washing with lukewarm water.
2. Choose gentle products: Opt for soap-free cleansers to preserve barrier function.
3. Select quality masks: Use soft, cotton-lined options changed frequently to reduce irritation.
4. Manage stress: Incorporate mindfulness or exercise to curb flare-inducing hormones.
5. Sustain treatments: Consult dermatologists virtually for refills and adjustments.

These steps helped many maintain control despite challenges.

Long-Term Lessons and Skin Health Outlook

Three years post-initial waves, skin manifestations evolved; early pandemic rashes like pernio waned with variants like Omicron. Eczema patients benefited from telemedicine, reducing exposure while ensuring care continuity. Future preparedness involves robust home management plans and awareness of how public health measures interact with chronic skin diseases.

Global prevalence studies during COVID-19 underscored steady eczema rates, unaffected by the virus but influenced by lifestyle shifts. Ongoing research emphasizes tailored prevention for at-risk groups, including those with comorbidities.
