Evaluation of the therapeutic effect of Sacha inchi oil in atopic dermatitis mice

Atopic dermatitis (AD) is a prevalent inflammatory skin condition characterized by a multifaceted pathogenesis, which encompasses immune system signaling dysregulation, compromised skin barrier function, and genetic influencers. Sacha inchi (Plukenetia volubilis L.) oil (SIO) has demonstrated potent anti-inflammatory and antioxidant properties, however, the mechanism underlying the beneficial effects of SIO on AD remains unclear. This study aims to investigate the anti-AD effect of SIO and its possible molecular mechanism in mice with AD. The results demonstrated that SIO significantly reduced the degree of skin lesions and scratching, and improved the skin thickness and mast cell infiltration in AD mice. Furthermore, SIO significantly reduced the levels of immunoglobulin E, histamine and thymic stromal lymphopoietin in serum of AD mice. Additionally, it inhibited the expression of tumor necrosis factor-γ, interferon-γ, interleukin-2, interleukin-4, interleukin 1β and other inflammatory cytokines in the lesions skin of mice. The Western blotting analysis revealed that SIO exhibited an upregulatory effect on the protein expression of filaggrin and loricrin, while concurrently exerting inhibitory effects on the protein expression and phosphorylation levels of P38, ERK, NF-κB, and IκBα within their respective signaling pathways. Consequently, it can be inferred that SIO exerts a significant anti-atopic dermatitis effect by modulating the P38, ERK, NF-κB, and IκBα signaling pathways. This study contributes to expand the research and development potential of SIO, and provides novel insights and potential therapeutic strategies for AD treatment.

Development of an Emulgel for the Effective Treatment of Atopic Dermatitis: Biocompatibility and Clinical Investigation

Atopic dermatitis (AD) is a common dermatological disease affecting both children and adults. No drug-free emulgel has been developed and studied in vitro and in vivo for the treatment of AD. The aim of this study was to develop and assess the efficacy of a topical emulgel containing hyaluronic acid, glycerol, Calendula officinalis, Aloe vera, polyphenols and EGF for the concomitant treatment in patients with AD aged over 14. Objective skin barrier function parameters were included, such as transepidermal water loss (TEWL), skin temperature, pH, stratum corneum hydration, skin elasticity and erythema. The subjective opinion of the patients was determined including acceptability, absorption, comfort of use and tolerability, as well as the degree of improvement in patients' quality of life. We observed an improvement in the subjective parameters studied and statistically significant differences in the objective parameters. Specifically, we found an improvement in TEWL (p = 0.006), erythema (p = 0.008) and hydration (p < 0.001), parameters indicating an improvement in the epidermal barrier. One hundred per cent of patients were satisfied with the product. Therefore, these results suggest that the product may contribute to the treatment of AD.

Coconut allergy: Characteristics of reactions and diagnostic predictors in a pediatric tertiary care center

BACKGROUND

Little is known on the clinical manifestations of coconut allergy. Our knowledge to date is mainly based on case reports.

OBJECTIVE

To characterize the allergic reactions to coconut and suggest diagnostic cutoffs for specific immunoglobulin E (sIgE) and skin prick testing (SPT) to predict clinically reactive coconut allergy.

METHODS

Methods include retrospective chart review at an urban tertiary care center of patients with positive testing result for coconut. Probability curves were computed by logistic regression for SPT and coconut sIgE.

RESULTS

Of 275 records reviewed, 69 patients reported coconut reactions and 206 were sensitized only or nonallergic. The reactions occurred with breastfeeding (n = 2), contact (n = 10), or oral ingestion (n = 57). Approximately 50% of oral ingestion reactions were associated with mild/moderate anaphylaxis. Clinical reactivity vs sensitization was more common in topical coconut users (2-fold) (P = .02). Although not statistically significant, there was a trend toward more coconut allergy vs sensitization in Asian and African American patients. The probability of allergy with positive SPT result was approximately 50% and with sIgE was approximately 60%. At an SPT of 9 mm wheal or sIgE of 58 kU of allergen/L, there is a 95% probability of reaction. Cosensitization with tree nuts, legumes, and seeds was common. Macadamia nut had the strongest correlation with coconut (r = 0.81, P < .001, n = 101).

CONCLUSION

Although the rate of reactivity to coconut in sensitized individuals is low, half of the reactions from consumption met the criteria for anaphylaxis. Clinicians should be aware of the spectrum of reactions and diagnostic use of sIgE and SPT.

A survey in uncharted territory: A collaborative study to explore the approach to atopic dermatitis patient management in allopathy and naturopathy

BACKGROUND

Atopic dermatitis (AD) patients frequently use both conventional and complementary medicines for treatment. Allopathic and naturopathic providers may be unaware of each other's approach to AD diagnosis, skin care, and treatment, affecting patient and provider communication, patient safety, and potential for collaborative studies.

OBJECTIVE

To identify core commonalities and differences in allopathic and naturopathic approach to AD.

METHODS

Thirty allopathic and 21 naturopathic providers completed an 11-question free-text comment survey, covering patient education and evaluation, skin care, and treatment of AD. Qualitative content analysis detected key ideas and concepts, and word cloud analysis provided a quantitative visual representation of recurrent words in each group's responses.

RESULTS

All respondents indicated using similar physical features to diagnose AD. In both allopathic and naturopathic fields, the majority of providers did not perform routine testing for AD diagnosis. Skin care with moisturization and "soak-and-seal" bathing practices were routine in both fields. Naturopathic providers heavily emphasized the role of food and diet in AD pathogenesis, education, and management, while allopathic providers indicated little to no role for food and diet in AD. For treatment, allopathic providers favored topical steroids, phototherapy, and immunomodulators, whereas naturopathic providers recommended botanicals, supplements, and other complementary and alternative methods.

CONCLUSIONS

Providers should be aware of the differences between allopathic and naturopathic providers and their approach to AD management, particularly concerning the role of food and diet. There may be opportunities to harmonize skin care regimens for patients given similar approach in both fields, and to collaborate further on studies of diet in AD and treatments not yet effectively tested.

Common Neonatal Rashes

Skin eruptions are commonly encountered in the neonatal and infant period and can be a source of concern for providers and parents alike. We present a brief, clinically focused discussion on topics commonly encountered by the pediatrician with a focus on pearls of knowledge to help distinguish diseases from one another and from more serious conditions. We review miliaria, transient neonatal pustular melanosis, neonatal cephalic pustulosis, erythema toxicum neonatorum, diaper dermatitis, seborrheic dermatitis, and atopic dermatitis. Treatment strategies are also discussed. [Pediatr Ann. 2019;48(1):e16-e22.].

In this review, we summarize the treatments for AD and recommendations for their use.

Atopic dermatitis in Indian children: The influence of lower socioeconomic status

Atopic dermatitis (AD) is a chronic inflammatory condition afflicting children and adults. In developing countries like India, the scenario is slightly different from its western counterparts, where the disease has been commonly described. Despite running a milder course, AD still has a significant negative impact on the quality of life. Environmental factors have a great influence on pathogenesis. While the diagnosis has remained clinical, variations in minor clinical features have been observed worldwide. Many indigenous and herbal agents are used for its treatment in India, in addition to conventional therapies. Treatment modalities in India emphasize less costly therapies and family education. This contribution reviews the epidemiologic issues and therapeutic differences in the Indian population with AD, highlighting important nuances in the care of the Indian patient.
