<h4>Background</h4>Atopic dermatitis (AD) (or atopic eczema) is a chronic inflammatory skin condition that affects children and adults and has an important impact on quality of life. Topical corticosteroids (TCS) are the first-line therapy for this condition; however, they can be associated with significant adverse effects when used chronically. Tacrolimus ointment (in its 2 manufactured strengths of 0.1% and 0.03%) might be an alternative treatment. Tacrolimus, together with pimecrolimus, are d ...[more]

Project description:PurposeManagement of atopic dermatitis (AD) typically requires application of topical treatments, often multiple times a day. The cosmetic properties and burdensome application of these treatments can be detrimental to quality of life (QoL). Patients who achieve good disease control through use of systemic therapies may reduce the frequency and amount of topical applications, improving QoL. This study aimed to quantify the utility and disutility for topical AD treatment processes.MethodsSeven vignettes describing different skincare regimens for people with moderate-to-severe AD were developed with input from healthcare professionals. 484 respondents from the general population completed time trade-off items for each vignette. Utility values for each regimen, and disutilities associated with the impact of changes to skincare regimens, were calculated. Analysis of variance assessed differences between skincare regimens.ResultsAs skincare regimens increased in intensity (0.7968 for the most intense; 0.9999 for the least), utility values decreased. There were no statistically significant differences between skincare regimens followed by patients with good disease control (0.9862 to 0.9999); however, when compared to those involving topical corticosteroids and emollient combinations (0.7968 to 0.8835), significant differences were observed (p < 0.001). The largest disutilities (0.1521 to 0.1705) were between skincare regimens describing the use of topical corticosteroids plus emollient and those followed by patients with good disease control.ConclusionsThe application of topical treatments has a detrimental effect on QoL, which increases with the duration and frequency of applications. Further research is needed to investigate how health and process utilities interact and both can be integrated into medical decision-making.

Project description:ObjectiveTo determine the efficacy and tolerability of topical pimecrolimus and tacrolimus compared with other treatments for atopic dermatitis.DesignSystematic review and meta-analysis.Data sourcesElectronic searches of the Cochrane Library, Medline, and Embase.Study selectionRandomised controlled trials of topical pimecrolimus or tacrolimus reporting efficacy outcomes or tolerability.Data extractionEfficacyinvestigators' global assessment of response; patients' global assessment of response; proportions of patients with flares of atopic dermatitis; and improvements in quality of life. Tolerability: overall rates of withdrawal; withdrawal due to adverse events; and proportions of patients with burning of the skin and skin infections.Data synthesis4186 of 6897 participants in 25 randomised controlled trials received pimecrolimus or tacrolimus. Both drugs were significantly more effective than a vehicle control. Tacrolimus 0.1% was as effective as potent topical corticosteroids at three weeks and more effective than combined treatment with hydrocortisone butyrate 0.1% (potent used on trunk) plus hydrocortisone acetate 1% (weak used on face) at 12 weeks (number needed to treat (NNT) = 6). Tacrolimus 0.1% was also more effective than hydrocortisone acetate 1% (NNT = 4). In comparison, tacrolimus 0.03% was more effective than hydrocortisone acetate 1% (NNT = 5) but less effective than hydrocortisone butyrate 0.1% (NNT = -8). Direct comparisons of tacrolimus 0.03% and tacrolimus 0.1% consistently favoured the higher strength formulation, but efficacy differed significantly between the two strengths only after 12 weeks' treatment (rate ratio 0.80, 95% confidence interval 0.65 to 0.99). Pimecrolimus was far less effective than betamethasone valerate 0.1% (NNT = -3 at three weeks). Pimecrolimus and tacrolimus caused significantly more skin burning than topical corticosteroids. Rates of skin infections in any of the comparisons did not differ.ConclusionsBoth topical pimecrolimus and topical tacrolimus are more effective than placebo treatments for atopic dermatitis, but in the absence of studies that show long term safety gains, any advantage over topical corticosteroids is unclear. Topical tacrolimus is similar to potent topical corticosteroids and may have a place for long term use in patients with resistant atopic dermatitis on sites where side effects from topical corticosteroids might develop quickly. In the absence of key comparisons with mild corticosteroids, the clinical need for topical pimecrolimus is unclear. The usefulness of either treatment in patients who have failed to respond adequately to topical corticosteroids is also unclear.

Project description:Objective: To review the efficacy and safety of crisaborole and its place in therapy for the management of mild to moderate atopic dermatitis (AD). Data Sources: A literature search of PubMed (data inception to February 2019) was performed using the search terms crisaborole and atopic dermatitis. Supplementary sources included the Journal of the American Academy of Dermatology Guidelines of Care for the Management of Atopic Dermatitis, clinicaltrials.gov data, manufacturer prescribing information, and article bibliographies. Study Selection and Data Extraction: Relevant English-language studies and those conducted in humans were considered and reviewed. Abstracts from clinical trials and drug reviews were reviewed. Phases I, II, III, and long-term safety studies were included. Data Synthesis: Data from multiple clinical trials have demonstrated the effectiveness and safety of crisaborole topical ointment. Patients treated with crisaborole experienced improvement in AD symptoms based on improvement in the Investigator’s Static Global Assessment and the AD Severity Index scores. Crisaborole has a limited adverse event profile and low systemic absorption. Relevance to Patient Care and Clinical Practice: Crisaborole is the first topical phosphodiesterase 4 inhibitor indicated for the treatment of mild to moderate AD. Its place in therapy is along with topical calcineurin inhibitors as a second-line option for patients who are recalcitrant to or unable to use topical corticosteroids. Conclusions: Crisaborole is a safe and efficacious second-line option for the treatment of mild to moderate AD in patients 2 years of age and older.

Project description:BACKGROUND:Skin barrier dysfunction plays a key role in atopic dermatitis (AD). This impairment is related to altered composition and metabolism of epidermal sphingolipids and a deficiency of ceramides. Glycosaminoglycans (GAGs), and especially hyaluronic acid, could be useful in the management of AD. This study aimed to evaluate the effects of a novel topical treatment consisting of sphingolipids and GAGs extracts in dogs with AD. This formulation is different from previously tested products because the sphingolipid extract contained high amounts of sphingomyelin, a precursor of ceramides, and this has been shown to enhance endogenous synthesis of ceramides and to increase lamellar-related structures in vitro. Thus, it was hypothesized that this formulation could improve clinical disease and skin barrier function in patients with AD. RESULTS:Twelve house dust mite (HDM) allergic atopic beagle dogs were randomized into two groups: control (n = 6; no treatment) or treatment (n = 6; topical sphingolipids and GAGs twice weekly for 8 weeks). Dogs were challenged with allergen twice weekly and the severity of dermatitis was scored using the canine atopic dermatitis and extent severity index (CADESI-03) once weekly. Skin barrier function (measurement of transepidermal water loss) and severity of pruritus (both pruritus visual analog scale [PVAS] and pruritus timed episodes) were assessed at 0, 4 and 8 weeks of treatment. Assessments were done by personnel unaware of group allocation. Complete blood count, serum biochemistry and stratum corneum (SC) lipidomics analyses were done at baseline and at week 8. Compared to baseline, significant increases in CADESI (P = 0.0003) and PVAS (P = 0.041) were observed only in the control group, and SC polyunsaturated fatty acids increased significantly only with treatment (P = 0.039). Compared to control, treatment group had a significantly lower CADESI after 1 week (P = 0.0078) and a significantly lower PVAS after 8 weeks (P = 0.0448). Treatment was well tolerated. CONCLUSIONS:In this study in dogs with AD, a new topical formulation containing sphingomyelin-rich sphingolipids plus GAGs extracts attenuated the clinical worsening induced by HDM, supporting its use in atopic patients, either as an adjunctive treatment or used as monotherapy in certain cases.

Project description:Topical agents that are currently available for the treatment of atopic dermatitis may represent a valid approach in the management of mild or mild-moderate cases, whereas they are often supplemented with systemic therapies for handling more complex or unresponsive cases. The most used compounds include topical corticosteroids and calcineurin inhibitors, although their use might be burdened by side effects, poor response, and low patient compliance. Consequently, new innovative drugs with higher efficacy and safety both in the short and long term need to be integrated into clinical practice. A deeper understanding of the complex pathogenesis of the disease has led to identifying new therapeutic targets and to the development of innovative therapeutics. This narrative review aims to collect data on selected promising topical drugs that are in an advanced stage of development.

Project description:Background: Atopic dermatitis (AD) aetiology is not exactly identified, but it is characterized by pruritic skin reactions with elevation in the levels of inflammatory markers. Despite the fact that Corticosteroids are the mainstay therapy in the management of AD, they have many local and systemic adverse effects. Objective: The aim of this study is to evaluate the efficacy and safety of topical tacrolimus ointment in comparison to topical hydrocortisone cream in the management of the AD of children diagnosed with AD. Patients and Methods: This study was conducted on 200 children with AD. They were simply randomized into two groups, the tacrolimus group treated with 0.03% topical tacrolimus ointment and the hydrocortisone group treated with 1% hydrocortisone cream twice daily during the 3 weeks study period. Results: At the end of the study, both the tacrolimus and hydrocortisone groups showed a significant decline in the mean serum level of IL-10, IL-17, and IL-23 (p < 0.05) when compared to their baseline levels. However, the tacrolimus group showed a more significant decrease (p < 0.05) in the mean serum level of IL-10, IL-17, and IL-23 as compared to the hydrocortisone group [Mean differences = 1.600, 95% CI: 0.9858-2.214; 1.300, 95% CI: 1.086-1.514 and 4.200, 95% CI: 3.321-5.079]. Moreover, the median mEASI decreased similarly from 32 to 21 in the tacrolimus group and from 30 to 22 in the hydrocortisone group (p > 0.05) [Median difference = -2.000, 95% CI: -2.651 to -1.349; Median difference = 1.000, 95% CI: 0.3489-1.651]. Mild to moderate transient stinging and erythema were the main adverse effects that showed higher incidence in the tacrolimus group than in the hydrocortisone group (p < 0.05). In most cases, they resolved within 3-4 days. Besides, tacrolimus ointment did not cause skin atrophy as compared to the hydrocortisone group (p < 0.05). Conclusion: Tacrolimus ointment is more beneficial than hydrocortisone cream in managing AD in children in terms of lowering the inflammatory markers, however, there is no difference on the dermatitis severity scale. Moreover, tacrolimus is safer with a better side effect profile compared to hydrocortisone. Trial Registration: The trial is registered at ClinicalTrials.gov (CT.gov identifier: NCT05324618).

Project description:Atopic dermatitis (AD) is a common skin disease involving important immune mechanisms. There is an unmet need for a treatment for this condition. Herein, we focused on elucidating the role of Bi2-xMnxO3 nanospheres (BM) in alleviating skin inflammation in AD-like C57BL/6 mice. The BM was fabricated via sacrificial templates and its biosafety was systematically evaluated. The BM was applied topically to skin lesions of AD-like C57BL/6 mice. The phenotypic and histological changes in the skin were examined carefully. The responses of barrier proteins, inflammatory cytokines and cells to BM were evaluated in HaCaT cells and AD mouse models. The data demonstrated that BM treatment alleviated the AD phenotypes and decreased the level of inflammatory factors, while increasing the expression of the barrier proteins filaggrin/involucrin in the skin. BM effectively reduced the expression of phosphorylated STAT6, which in turn reduced the expression of GATA3, and further decreased the differentiation ratio of Th2 cells, thereby reducing the expression of IL-4. In conclusion, topical drug therapy with BM provides a safe and effective treatment modality for AD by reducing IL-4 and increasing barrier proteins.

Project description:The retinoic acid receptor-related orphan receptors RORα and RORγ are critical for the functions of specific subsets of T cells and innate lymphoid cells, which are key drivers of inflammatory disease in barrier tissues. Here, we investigate the anti-inflammatory potential of SR1001, a synthetic RORα/γ inverse agonist, in mouse models of atopic dermatitis and acute irritant dermatitis. Topical treatment with SR1001 reduces epidermal and dermal features of MC903-induced atopic dermatitis-like disease and suppresses the production of type 2 cytokines and other inflammatory mediators in lesional skin. In the epidermis, SR1001 treatment blocks MC903-induced expression of TSLP and reverses impaired keratinocyte differentiation. SR1001 is also effective in alleviating acute dermatitis triggered by 12-O-tetradecanoylphorbol-13-acetate. Overall, our results suggest that RORα/γ are important therapeutic targets for cutaneous inflammation and suggest topical usage of inhibitory ligands as an approach to treating skin diseases of inflammatory etiology.

Project description:The skin produces cortisol by itself and regulates its own proliferation and differentiation. There is a possibility that topical corticosteroids (TCSs) influence the cortisol homeostasis in the skin.The author described the density and distribution of cortisol and its parties in the epidermis after application of topical steroids immunohistologically.The forearm skin was biopsied before and after 2 weeks' application of clobetasol propionate 0.05% two times a day in one healthy volunteer. The biopsied skin was stained immunohistologically by ant-MLN64, StAR, CPY11A1, cortisol, HSD11B1, HSD11B2, glucocorticoid receptor alpha, glucocorticoid receptor beta (GRB), and mineralocorticoid receptor (MCR) antibodies. The skin biopsy was performed similarly in 19 adult patients with atopic dermatitis who had used TCS for a considerable period. They were 4 TCS present users (TCS+), 12 TCS nonusers with skin manifestation on the biopsied site (TCS-E+) and 3 TCS nonusers without skin manifestation on the biopsied site (TCS-E-).The staining density increased during TCS application in MLN64, cortisol and HSD11B2 in a healthy volunteer. The staining density was stronger in HSD11B2 of the basal layer and MCR of the spinous layer in the TCS-E+ patients than in the TCS+ and TCS-E- patients. The staining density was weaker in MLN64 of the basal and granular layers, HSD11B1 of the basal layer and GRB of the whole layer in the TCS-E+ patients than in the TCS+ and TCS-E- patients.The hypertrophy of the epidermis and insufficient keratinization recognized in the TCS-E+ patients might be caused by the decreased cortisol synthesis regulated by MLN64 and the increased cortisol inactivation by HSD11B2. Decreased GRB and increased MCR might enhance the reactivity of cortisol in the keratinocytes.

Project description:The underlying pathology of atopic dermatitis (AD) includes impaired skin barrier function, susceptibility to Staphylococcus aureus skin infection, immune dysregulation, and cutaneous dysbiosis. Our recent investigation into the potential role of Gram-negative skin bacteria in AD revealed that isolates of one particular commensal, Roseomonas mucosa, collected from healthy volunteers (HVs) improved outcomes in mouse and cell culture models of AD. In contrast, isolates of R. mucosa from patients with AD worsened outcomes in these models. These preclinical results suggested that interventions targeting the microbiome could provide therapeutic benefit for patients with AD. As a first test of this hypothesis in humans, 10 adult and 5 pediatric patients were enrolled in an open-label phase I/II safety and activity trial (the Beginning Assessment of Cutaneous Treatment Efficacy for Roseomonas in Atopic Dermatitis trial; BACTERiAD I/II). Treatment with R. mucosa was associated with significant decreases in measures of disease severity, topical steroid requirement, and S. aureus burden. There were no adverse events or treatment complications. We additionally evaluated differentiating bacterial metabolites and topical exposures that may contribute to the skin dysbiosis associated with AD and/or influence future microbiome-based treatments. These early results support continued evaluation of R. mucosa therapy with a placebo-controlled trial.
