Clinical recommendations for treatment of atopic dermatitis (AD) in Africa and the Middle East

Type of treatment Recommendation Merits Drawbacks
Emollients and moisturizers

• Emollients should be the mainstay of treatment

• Should be applied at least 5 times/day (acute) or 3 times/day (maintenance)

• Improve skin barrier function and symptoms [16, 70]

• Reduce need for prescription anti-inflammatory therapies [16, 71]

• Generally affordable treatment option [16, 72]

• Insufficient for moderate to severe cases [16, 18]

• Greasiness/smell of moisturizer, frequent application, and adverse reactions may lead to poor adherence [72]

• Specialized emollients and prescription emollient devices can be costly [16, 20]

Topical corticosteroids (TCSs) • Should be applied 2 times/day for 7 days (acute); then 1 time/day for 7 days or twice weekly (maintenance)

• Recommended first-line anti-inflammatory therapy [16, 1820]

• Effective with satisfactory safety profile when used as directed [16, 73, 74]

• Low cost for prescription therapy with several generic options [74, 75]

• Potential for long-term local side effects such as skin atrophy and systemic side effects such as HPA axis suppression merits routine monitoring [74]

• Limited use in children [74]

• Potential for hypopigmentation in patients with skin of color [74]

Topical calcineurin inhibitors (TCIs) • Should be applied 2 times/day for 1 month (acute); then 2 times/week (maintenance)

• Effective for short- and long-term treatment of mild to severe AD in adults and children [16, 7679]

• Steroid sparing; reduces need for TCS when used for long-term, proactive prevention of flares [80]

• Useful for sensitive areas (face, genitals, skin folds) [16, 20]

• Higher cost prescription therapy [75]

• Local tolerability issues (stinging/burning) may require patient counseling to prevent nonadherence [16, 18]

• Limited in combination with phototherapy as sun exposure should be avoided during TCI treatment [81, 82]

• FDA boxed warning for cancerogenesis [81, 82]

Topical PDE4 inhibitors

• Crisaborole ointment, 2%, should be applied 2 times/day

• Maintenance algorithm is not yet defined

• Effective treatment for mild to moderate AD in children and adults ≥ 2 years of age [83] with satisfactory short- and long-term safety profile [83, 84]

• Cost-effectiveness unestablished [85]

• Limited real-word effectiveness, head-to-head comparative efficacy, and safety data available [20]

• Local tolerability events including application site pain among most common treatment-related adverse events in pivotal [83] and long-term safety trials [84]

• Currently approved only in USA [24]

Systemic therapies

• Sedating antihistamines at bedtime; nonsedating antihistamines during the day if necessary

• Systemic immunosuppressants (methotrexate, cyclosporine, azathioprine) or biologics as second- or third-line therapies

• Antihistamines: widely available with low side effect profile (second-generation H1 antagonists) [86]

• Systemic immunosuppressants: effective in moderate to severe cases [73, 87, 88]

• Biologics: dupilumab effective in moderate to severe cases [89]

• Antihistamines: efficacy in AD unproven [90], recently associated with ADHD symptoms in children with AD [91]

• Systemic immunosuppressants: limited long-term use [17, 73]; pronounced side effect profile necessitates close monitoring [17, 73]

• Biologics: very cost intensive [92]; some are investigational and lack long-term safety and efficacy data in AD [17, 18, 21]; dupilumab approved only in USA [25], Europe [25], Canada [26], and Japan [27]

Other

• UV phototherapy if unresponsive to topical therapies

• Education regarding appropriate skin care

• Avoidance of triggers (e.g., scented soaps)

• Behavioral modifications and patient education: cost effective with good efficacy [21, 23]

• UV phototherapy: effective with good side effect profile [93]

• UV therapy: high costs (machine and maintenance) [20, 93]; requires patient access to a phototherapy center and frequent visits [20, 93]; limited long-term use and use in hairy/intertriginous areas [93]
