“…50 In addition, some topical retinoids also have direct antiinflammatory activity. 43,51,52 At present, 3 topical retinoids (tretinoin, adapalene, and tazarotene) are available by prescription in the United States. Each is available in a variety of formulations and concentrations (Table 4).…”

Evidence-Based Recommendations for the Diagnosis and Treatment of Pediatric Acne

et al. 2013

INTRODUCTION: Acne vulgaris is one of the most common skin conditions in children and adolescents. The presentation, differential diagnosis, and association of acne with systemic pathology differs by age of presentation. Current acknowledged guidelines for the diagnosis and management of pediatric acne are lacking, and there are variations in management across the spectrum of primary and specialty care. The American Acne and Rosacea Society convened a panel of pediatric dermatologists, pediatricians, and dermatologists with expertise in acne to develop recommendations for the management of pediatric acne and evidence-based treatment algorithms. METHODS: Ten major topic areas in the diagnosis and treatment of pediatric acne were identified. A thorough literature search was performed and articles identified, reviewed, and assessed for evidence grading. Each topic area was assigned to 2 expert reviewers who developed and presented summaries and recommendations for critique and editing. Furthermore, the Strength of Recommendation Taxonomy, including ratings for the strength of recommendation for a body of evidence, was used throughout for the consensus recommendations for the evaluation and management of pediatric acne. Practical evidence-based treatment algorithms also were developed. RESULTS: Recommendations were put forth regarding the classification, diagnosis, evaluation, and management of pediatric acne, based on age and pubertal status. Treatment considerations include the use of over-the-counter products, topical benzoyl peroxide, topical retinoids, topical antibiotics, oral antibiotics, hormonal therapy, and isotretinoin. Simplified treatment algorithms and recommendations are presented in detail for adolescent, preadolescent, infantile, and neonatal acne. Other considerations, including psychosocial effects of acne, adherence to treatment regimens, and the role of diet and acne, also are discussed. CONCLUSIONS: These expert recommendations by the American Acne and Rosacea Society as reviewed and endorsed by the American Academy of Pediatrics constitute the first detailed, evidence-based clinical guidelines for the management of pediatric acne including issues of special concern when treating pediatric patients.

“…Adapalene Has Anti-Inflammatory Activity Additional pharmacological activity for adapalene was obtained in model systems de signed to evaluate the anti-inflammatory ac tivity of substances [17], The topical anti inflammatory activity of adapalene tested in vivo was found to be moderate to strong and comparable with reference substances, such as betamethasone 17-valerate and indomethacin, and in general to be largely superior to the reference retinoids tested. A single topical application of arachidonic acid to the ears of mice induces an inflammation attributable to both lipoxygenase and cyclo-oxygenase prod ucts.…”

Adapalene, a New Chemical Entity with Retinoid Activity

Adapalene is a novel chemical entity which, in terms of pharmacology, behaves similar to tretinoin, but is chemically and photochemically stable. It has a particular selectivity profile for the known nuclear retinoic acid receptors with low affinity for RARΑ and no transactivating potential for RXRΑ. This receptor profile could imply that adapalene, in contrast to tretinoin, affects the terminal differentiation pathway of epidermal cells rather than their proliferation. Furthermore, adapalene does not bind to members of the cellular retinoic acid binding protein family. Adapalene has comedolytic activity in the topical rhino mouse model. It exerts a moderate-to-potent anti-inflammatory effect in a series of in vitro and in vivo models. In comparative clinical studies involving 72 acne patients, the efficacy of adapalene was comparable, if not superior, to tretinoin, but adapalene was better tolerated. The data reviewed in this paper indicate that adapalene should be particularly beneficial in the treatment of acne.

“…The number of acne lesions was reduced by between 49 and 62%. The comparison of tretinoin microsphere formulation demonstrated a similar efficacy but lower irritative potential of adapalene [30, 31, 32, 33]. …”

During the last 20 years, the number of topical and systemic drugs for the treatment of acne vulgaris has been enriched. Topical drugs on the one hand have been newly discovered or further developments of already available agents such as in the group of retinoids or galenic formulation have improved efficacy or local tolerance. Topical retinoids are a mainstay in acne treatment since 1962. All-trans retinoic acid was the first and is still in use. Its irritative potential has led to the new galenics, i.e. incorporation in microsponges and in propolyomers, which increased the tolerability significantly. The isomer of tretinoin, isotretinoin, has the same clinical efficacy, but also a lower irritancy. A real breakthrough was adapalene, a retinoid-like agent, with a different retinoid receptor-binding profile, but in addition to the same clinical efficacy on inflammatory and non-inflammatory acne lesions compared to tretinoin, a better tolerability and, therefore, compliance. Unfortunately, over the past years topical retinoids have been less used in inflammatory acne than they should be, taking the the mechanisms of action into account. Topical antimicrobials, in particular topical antibiotics, should be used less often than in the past and only for short periods to avoid the development of resistances. It seems better to combine those agents with topical retinoids, with BPO or with azelaic acid to enhance the efficacy and slow down the development of resistance. BPO is still the gold standard for papular-pustular acne of mild-to-moderate type in concentrations of 2–5%. Azelaic acid is an alternative with efficacy on the comedo and is antibacterial without development of resistances. Finally, the physical removal by electrocautery or CO₂ laser of multiple densely packed closed comedones, macrocomedones and microcysts is necessary to enhance the efficacy of topical comedolytic agents and to speed up the therapeutic results. Photodynamic therapy has not yet been proven efficacious in controlled studies. Blue and red light can probably be used in association with local agents but enhancement of the irritative potential of topical and systemic agents has to be considered.
