Abstract
Allergic contact dermatitis (ACD) is a common inflammatory skin disease that, especially when the condition becomes chronic, has a high impact on the quality of life and represents a significant disease burden. ACD represents a type IV delayed-type hypersensitivity reaction that is triggered by contact with an allergen in previously sensitized individuals through the activation of allergen-specific T cells. In the acute phase, it is characterized by eczematous dermatitis, which presents with erythema, edema, vesicles, scaling, and intense itch. Non-eczematous clinical forms are also described (lichenoid, bullous, and lymphomatosis). Lichenification is the most common clinical picture in the chronic phase if the culprit allergen is not found or eliminated. ACD can be associated with both occupational and non-occupational exposure to allergens, representing approximately 90% of occupational skin disorders along with irritant contact dermatitis. Patch testing with suspected allergens is required for a diagnosis. Metals, especially nickel, fragrance mix, isothiazolinones, and para-phenylenediamine, are the most commonly positive allergens in patients patch tested for suspected ACD. The treatment goal is to avoid contact with the culprit agent and use topical and/or systemic corticosteroid therapy.

Mawson AR. Understanding health disparities affecting people of West Central African descent in the United States: An evolutionary perspective. Evol Appl 2023; 16:963-978. [PMID: 37216026 PMCID: PMC10197229 DOI: 10.1111/eva.13549] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/28/2022] [Revised: 03/19/2023] [Accepted: 04/02/2023] [Indexed: 05/24/2023] Open
Abstract
Human populations adapting to diverse aspects of their environment such as climate and pathogens leave signatures of genetic variation. This principle may apply to people of West Central African descent in the United States, who are at increased risk of certain chronic conditions and diseases compared to their European counterparts. Less well known is that they are also at reduced risk of other diseases. While discriminatory practices in the United States continue to affect access to and the quality of healthcare, the health disparities affecting African Americans may also be due in part to evolutionary adaptations to the original environment of sub-Saharan Africa, which involved continuous exposure to the vectors of potentially lethal endemic tropical diseases. Evidence is presented that these organisms selectively absorb vitamin A from the host, and its use in parasite reproduction contributes to the signs and symptoms of the respective diseases. These evolutionary adaptations included (1) sequestering vitamin A away from the liver to other organs, to reduce accessibility to the invaders; and (2) reducing the metabolism and catabolism of vitamin A (vA), causing it to accumulate to subtoxic concentrations and weaken the organisms, thereby reducing the risk of severe disease. However, in the environment of North America, lacking vA-absorbing parasites and with a mainly dairy-based diet that is high in vA, this combination of factors is hypothesized to lead to the accumulation of vA and to increased sensitivity to vA as a toxin, which contribute to the health disparities affecting African Americans. vA toxicity is linked to numerous acute and chronic conditions via mitochondrial dysfunction and apoptosis. Subject to testing, the hypothesis suggests that the adoption of traditional or modified West Central African-style diets that are low in vA and high in vA-absorbing fiber hold promise for disease prevention and treatment, and as a population-based strategy for health maintenance and longevity.

Abstract
Introduction: Acne vulgaris is a widespread skin disease. Topical therapy is a standard treatment for mild to moderate acne. Given the complex pathophysiology of acne, various agents with complementary action are nowadays frequently combined to increase the efficacy of therapy.Area covered: This review focus on safety profile of topical agents used for the treatment of acne vulgaris, including topical retinoids, benzyl peroxide, azelaic acid, topical antibiotic, and combined agents. Data from clinical trials but also metanalyses, systematic reviews, and other secondary analyses are presented.Expert opinion: In general, topical agents used for acne vulgaris have a favorable safety profile. The most commonly reported AEs were associated with local skin irritation, usually mild to moderate in intensity, intermittent, and rarely led to the cessation of therapy. Irritative potential seems to be highest for BPO and topical retinoids. Due to the possibility of development of Cutibacterium acnes resistance, topical antibiotics should not be used in monotherapy but as a part of combination therapy. In female adolescent and adults of childbearing potential, topical retinoids should be used with caution, because they are contraindicated in pregnant females (FDA Pregnancy category) C (adapalene, tretinoin) and X (tazarotene).

Efficacy and tolerability of short contact therapy with tretinoin, clindamycin, and glycolic acid gel in acne: A randomized, controlled, assessor-blinded two-center trial: The MASCOTTE study. Dermatol Ther 2021; 34:e14724. [PMID: 33377285 DOI: 10.1111/dth.14724] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/25/2020] [Revised: 12/18/2020] [Accepted: 12/22/2020] [Indexed: 11/30/2022]
Abstract
Retinoids and antibiotics topical treatments are commonly used as first line therapy in mild to moderate acne. However, irritant contact dermatitis is a common side effect of topical retinoids. A strategy to increase local tolerability is the "short contact therapy" (SCT) approach, consisting in the application of the product with the complete removal after 30 to 60 minutes using a non-aggressive cleanser. A gel containing tretinoin 0.02%, clindamycin 0.8%, and glycolic acid 4% in polyvinyl alcohol (MP-gel) has shown to be effective as monotherapy in mild to moderate acne with a tolerability profile similar to other topical retinoids. So far, no trials have been performed with this gel comparing the tolerability profile of SCT with standard application therapy (SAT). We conducted a 2-center randomized parallel groups, controlled, assessor-blinded study, comparing MP-gel applied as SCT in comparison with MP-gel used as SAT (The "MASCOTTE" trial). Forty-six subjects (nine men and 37 women, mean age 23 ± 4 years, range 18-31 years) with mild-to-moderate acne were enrolled, after their written informed consent in a randomized, parallel groups controlled, assessor-blinded 8-week trial. Twenty-three were assigned to MP-gel once daily (evening application) using the SCT approach (ie, complete removal of product after 1 hour using a gentle cleanser), and 23 were randomized to the SAT approach with the same gel. The primary endpoint was the evolution of the tolerability score (TS) assessed evaluating four items: erythema, dryness, stinging, and burning, using a 4-point score scale (from 0: no symptom to 3: severe symptom). Secondary endpoints were the evolution of global acne grading system (GAGS) score (range: from 0 to >39) and the investigator global assessment (IGA of acne severity) score (range from 0 to 4). TS was evaluated at 2, 4, and 8 weeks. GAGS and IGA scores were evaluated at baseline and at week eight. At week eight, an efficacy global score (EGS) (from 1: no efficacy to 4: very good efficacy) and a tolerability global score (TGS) (from 1: very low tolerability to 3: very good tolerability) evaluation were also done. All the evaluations were performed by an investigator unaware of treatment groups allocation (SCT or SAT). Thirty-eight subjects (83%) completed the 8-week treatment period. Eight subjects (two in the SCT group and six in the SAT group) dropped out prematurely due to low skin tolerability. In the SCT the TS at week two was 1.3 ± 1.7, in the SAT group TS was significantly higher (3.1 ± 1.7) (P = .028). TS was significantly lower in SCT group vs SAT also at weeks four and eight (P = .01; ANOVA test). The GAGS score at baseline was 19 ± 7 in the SCT group and 23 ± 4 in the SAT group (NS). At week 8 the GAGS score in SCT was significantly reduced to 8.5 ± 2.8 (-55%) (P = .001 vs baseline) and was also significantly lower in comparison with SAT group (8.5 vs 15; P = .0054). The IGA scores at baseline were 1.9 ± 0.6 in SCT and 2.4 ± 0.7 in SAT group. At week eight, in comparison with baseline values IGA score was reduced significantly by 48% in SCT and by 30% in SAT. EGS and TGS were significantly higher (better clinical efficacy and better tolerability) in SCT in comparison with SAT (3.6 ± 0.5 and 2.9 ± 0.3 vs 2.7 ± 0.6 and 1.5 ± 0.7; respectively). This tretinoin, clindamycin, glycolic acid gel, applied as SCT, has shown a better skin tolerability and at least a comparable clinical efficacy in comparison with the standard application modality in the treatment of mild-to-moderate acne. The SCT therefore could be an effective treatment strategy which could improve subjects' compliance and adherence.

Abstract
BACKGROUND Retinoic acid (RA)-induced dermatitis is the most frequent side-effect limiting its widespread use. However, the exact mechanisms triggering dermatitis are not fully understood, including the role of skin mast cells. The newly discovered Mas-related G-protein-coupled receptor-X2 (MRGPRX2) in mast cells mediates pseudoallergic drug reactions in several types of dermatitis. A possible contribution of MRGPRX2 to contact dermatitis induced by RA has hitherto not been examined. OBJECTIVES To investigate whether all-trans-RA (ATRA) activates mast cells via MRGPRX2/MrgprB2 (the mouse orthologue), contributing to the pathogenesis of retinoid-induced dermatitis. METHODS Wild-type (WT) and MrgprB2-/- mice were treated with topical ATRA to observe local inflammation and mast cell degranulation in vivo by the use of haematoxylin and eosin and immunofluorescence staining. Release of histamine and release of β-hexosaminidase were measured and calcium influx was detected in Laboratory of Allergic Disease 2 (LAD2) cells with specific knockdown targeting MRGPRX2 by small interfering RNA (siRNA) and in primary cells from MrgprB2-/- mice. RESULTS As compared with WT mice, MrgprB2-/- mice showed resistance to ATRA-triggered contact dermatitis and local inflammatory reactions in the paws. ATRA activated mast cells via the MrgprB2 pathway in murine cells, and via the MRGPRX2 pathway in human mast cells. CONCLUSIONS ATRA-induced dermatitis could be achieved by activating mast cells via MRGPRX2/MrgprB2, which may provide a potential therapy target to reduce the side-effect.

Abstract
Topical drugs have been used successfully to treat acne for decades. This review discusses the use, efficacy, and safety of options available via prescription. Topical antibiotics, dapsone, benzyl peroxide, azelaic acid, and topical retinoids are included. Topical antibiotics should not be used as monotherapy but rather be combined with other agents to avoid resistant Propionibacterium acnes strains. Benzoyl peroxide is effective in preventing bacteria resistance. Topical retinoids address primarily the comedonal but also the inflammatory lesions of acne. Azelaic acid is useful in treating acne lesions and for lightening postinflammatory hyperpigmentation that may accompany inflammatory acne lesions. Combinations of agents that address different aspects of acne pathogenesis may offer higher benefit to acne patients.
