[PMID: 37439364 DOI: 10.1111/1440-1681.13809] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/12/2023] [Revised: 06/13/2023] [Accepted: 06/19/2023] [Indexed: 07/14/2023]
Abstract
Atopic dermatitis (AD) is a chronic inflammatory skin condition with a high prevalence. Inflammation and oxidative stress are strongly associated with AD progression. Esculentoside A (EsA) inhibits inflammation and oxidative stress in various diseases. However, whether EsA mitigates AD by suppressing inflammation and oxidative stress remains unknown. A mouse model of AD was constructed by the induction of 1-chloro-2,4-dinitrochlorobenzene (DNCB). The mechanism of EsA and its effects on AD symptoms, pathology, inflammation and oxidative stress were investigated through histopathological staining, enzyme-linked immunosorbent assay, blood cells analysis, colorimetric measurement and western blot analysis. EsA improved the clinical symptoms and increased clinical skin scores in AD mice. Skin thickening of the epidermis and dermal tissues and the mast cell numbers in AD mice were reduced with the EsA treatment. EsA decreased the relative mRNA level of thymic stromal lymphopoietin, interleukin (IL)-4, IL-5 and IL-13; the serum concentrations of immunoglobulin E (IgE) and IL-6; and the numbers of white blood cells (WBC) and WBC subtypes, including basophil, lymphocytes, eosinophil, neutrophil and monocytes in DNCB-induced mice. DNCB caused higher levels of oxidative stress, which was reversed with the administration of EsA. Mechanically, EsA upregulated the expression of Nrf2 but downregulated the level of NLRP3 inflammasome in AD mice. The inhibitor of Nrf2 significantly recovered the EsA-induced changes in the NLRP3 inflammasome proteins in DNCB-treated mice. Therefore, EsA improved the clinical and pathological symptoms, inflammation and oxidative stress experienced by DNCB-induced mice and was involved in the inactivation of NLRP3 inflammasome by activating Nrf2.

Zhao S, Hwang A, Miller C, Lio P. Safety of topical medications in the management of paediatric atopic dermatitis: An updated systematic review. Br J Clin Pharmacol 2023; 89:2039-2065. [PMID: 37075252 DOI: 10.1111/bcp.15751] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/13/2023] [Revised: 03/08/2023] [Accepted: 03/28/2023] [Indexed: 04/21/2023] Open
Abstract
AIM New topical agents have been developed for the treatment of atopic dermatitis (AD) in recent years. This systematic review is intended to synthesize the clinical trial literature and concisely report the updated safety and adverse effects of topical medications used to treat atopic dermatitis in children. METHODS A systematic search of Cochrane Library, Embase, PubMed and ClinicalTrials.gov from inception to March 2022 was conducted for trials of topical medications used to treat AD in patients <18 years (PROSPERO #CRD42022315355). Included records were limited to English-language publications and studies of ≥3 weeks duration. Phase 1 studies and those that lacked separate paediatric safety reporting were excluded. RESULTS A total of 5005 records were screened; 75 records met inclusion criteria with 15 845 paediatric patients treated with tacrolimus, 12 851 treated with pimecrolimus, 3539 with topical corticosteroid (TCS), 700 with crisaborole and 202 with delgocitinib. Safety data was well reported in tacrolimus trials with the most frequently reported adverse events being burning sensation, pruritus and cutaneous infections. Two longitudinal cohort studies were included, one for tacrolimus and one for pimecrolimus, which found no significant increased risk of malignancy with topical calcineurin inhibitor (TCI) use in children. Skin atrophy was identified as an adverse event in TCS trials, which other medications did not. Systemic adverse events for the medications were largely common childhood ailments. CONCLUSION Data discussed here support the use of steroid-sparing medications (tacrolimus, pimecrolimus, crisaborole, delgocitinib) as safe options with minimal adverse events for managing paediatric AD, although a larger number of TCI studies reported burning and pruritus compared to TCS studies. TCS was the only medication class associated with reports of skin atrophy in this review. The tolerability of these adverse events should be considered when treating young children. This review was limited to English-language publications and the variable safety reporting of trial investigators. Many newer medications were not included due to pooled adult and paediatric safety data that did not meet inclusion criteria.

Abstract
BACKGROUND Tacrolimus ointment is a recently developed topical immunomodulator that has been approved for use in patients with vitiligo older than 2 years. Concern regarding potential systemic toxic effects has limited treatment options for children younger than 2 years. We wanted to determine whether topical tacrolimus therapy is safe and effective in patients with vitiligo younger than 2 years. METHODS The present 6-month clinical trial was conducted to evaluate the efficacy and safety of 0.03% tacrolimus in the treatment of vitiligo in children under 2 years of age. Meanwhile, serum and urine samples were collected, and liquid chromatography-mass spectrometry was performed to generate the serum and urine metabolic profile data of patients and healthy controls. RESULTS The overall response rate at the sixth month, which was defined by the degree of re-pigmentation, was 100%. As revealed by blood monitoring and metabolite detection 6 months later, there was no difference between the treatment group and the control group. There is no evidence that long-term topical application of 0.03% tacrolimus ointment will cause metabolite or other physical changes in the body. CONCLUSIONS Tacrolimus ointment appears to be effective and safe in the treatment of vitiligo in children younger than 2 year. TRIAL REGISTRATION http://www.chictr.org.cn identifier: ChiCTR 2100045920. IMPACT We first reported the efficacy and safety of topical application of 0.03% tacrolimus ointment in infants with vitiligo characterized by the metabolites. There is no evidence that long-term topical application of 0.03% tacrolimus ointment will cause metabolite or other physical changes in the body. This study provide evidence for the TCI treatment of infants with vitiligo.

Cancer risk with topical calcineurin inhibitors, pimecrolimus and tacrolimus, for atopic dermatitis: a systematic review and meta-analysis. THE LANCET. CHILD & ADOLESCENT HEALTH 2023; 7:13-25. [PMID: 36370744 DOI: 10.1016/s2352-4642(22)00283-8] [Citation(s) in RCA: 17] [Impact Index Per Article: 17.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/03/2022] [Revised: 09/22/2022] [Accepted: 09/23/2022] [Indexed: 11/11/2022]
Abstract
BACKGROUND Atopic dermatitis is a prevalent condition in children and can be effectively managed with medications such as topical calcineurin inhibitors (pimecrolimus or tacrolimus). A key unresolved safety concern is whether use of topical calcineurin inhibitors is associated with cancer. We systematically reviewed the risk of cancer in patients with atopic dermatitis exposed to topical calcineurin inhibitors. METHODS As part of the 2022 American Academy of Allergy, Asthma and Immunology and American College of Allergy, Asthma and Immunology Joint Task Force on Practice Parameters atopic dermatitis guidelines, we searched MEDLINE, Embase, the Latin American and Caribbean Health Sciences Literature database, the Índice Bibliográfico Espanhol de Ciências da Saúde database, the Global Resource of Eczema Trials database, WHO's International Clinical Trials Registry Platform, the US Food and Drug Administration database, the European Medicines Agency database, company registers, and relevant citations from inception to June 6, 2022. We included randomised controlled trials and comparative and non-comparative non-randomised studies in any language addressing cancer risk in patients with atopic dermatitis using topical calcineurin inhibitors. We excluded split-body studies and studies with less than 3 weeks of follow-up. Paired reviewers independently screened records, extracted data, and assessed risk of bias in duplicate. We used Bayesian models to estimate the probability for cancer due to topical calcineurin inhibitor exposure and the GRADE approach to determine the certainty of the evidence. Patients, advocacy groups, and care providers set a priori thresholds of important effects. This study is registered with Open Science Framework, https://osf.io/v4bfc. FINDINGS We identified and analysed 110 unique studies (52 randomised controlled trials and 69 non-randomised studies [11 were non-randomised study extensions of randomised controlled trials]) including 3·4 million patients followed up for a mean of 11 months (range 0·7-120). The absolute risk of any cancer with topical calcineurin inhibitor exposure was not different from controls (absolute risk 4·70 per 1000 with topical calcineurin inhibitors vs 4·56 per 1000 without; odds ratio 1·03 [95% credible interval 0·94-1·11]; moderate certainty). For all age groups and using data from observational studies and randomised controlled trials, the use of pimecrolimus (OR 1·05 [95% credible interval 0·94-1·15]) or tacrolimus (0·99 [0·89-1·09]) is likely to have had little to no association with cancer compared with no topical calcineurin inhibitor exposure. For pimecrolimus versus tacrolimus, the finding was similar (0·95 [95% credible interval 0·83-1·07]). Findings were similar in infants, children, and adults, and robust to trial sequential, subgroup, and sensitivity analyses. INTERPRETATION Among individuals with atopic dermatitis, moderate-certainty evidence shows that topical calcineurin inhibitors do not increase the risk of cancer. These findings support the safe use of topical calcineurin inhibitors in the optimal treatment of patients with atopic dermatitis.

Abstract
Introduction Atopic dermatitis (AD) is a chronic, pruritic, inflammatory skin disease with rising prevalence. Topical corticosteroids (TCS) are recommended as first-line therapy for patients with AD in China; however, corticophobia is a widespread concern, which can manifest as noncompliance: in a previous Chinese study, almost all parents whose children had AD were very concerned about the side effects of TCS and, as a result, nearly half did not use it in the event of recurrence. We propose a TCS-sparing treatment algorithm for the management of infants, children, adolescents, and adults with mild-to-moderate AD, to guide clinical practice in China. Methods A panel of eight experts in AD from China and one expert from Germany formed to develop a practical algorithm for the management of mild-to-moderate AD, focusing on pimecrolimus. Results Irrespective of body location, all patients with mild AD (including acute flares) and infants with moderate AD should apply the topical calcineurin inhibitor (TCI) pimecrolimus twice daily to the affected area until symptoms disappear. For children, adolescents, and adults with moderate AD, pimecrolimus should be applied twice daily to sensitive skin areas, and a TCI (either pimecrolimus or tacrolimus) should be applied twice daily to other body locations. Short-term administration of TCS, followed by TCI twice daily, is recommended for most patients with moderate AD experiencing acute flares, regardless of lesion site. Emollients should be used regularly. Conclusions The algorithm presented intends to simplify treatment of AD in China and guide clinical decision-making.

PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2021; 91:153708. [PMID: 34455178 DOI: 10.1016/j.phymed.2021.153708] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/18/2021] [Revised: 08/09/2021] [Accepted: 08/10/2021] [Indexed: 06/13/2023]
Abstract
PURPOSE Rosa davurica Pall., is mainly distributed in Korea, Japan, northeastern China, southeastern Siberia, and eastern Asia. It has been extensively used to treat various kinds of diseases by reason of the significant antioxidant, antiviral and anti-inflammatory activities. However, the pharmacological mechanism of Rosa davurica Pall. in atopic dermatitis (AD) is still ill defined and poorly understood. This study was to examine the anti-inflammatory effects and its mechanism on AD of Rosa davurica Pall. leaves (RDL). METHODS To evaluate the therapeutic potential of RDL against AD, we have investigated the effects of RDL on the inflammatory reactions and the productions of inflammatory chemokines and cytokines that were induced by tumor necrosis factor-α (TNF-α)/interferon-γ (IFN-γ) in HaCaT cells. Futhermore, we examined the effects of RDL on the signaling pathways of mitogen-activated protein kinase (MAPK) and nuclear factor-kappa B (NF-κB). For the in-vivo studies, RDL extract was topically applied to the dinitrochlorobenzene (DNCB)-induced AD mice, then its therapeutic effect was evaluated physiologically and morphologically. RESULTS After the stimulation of HaCaT cells with TNF-α/IFN-γ, RDL considerably reduced the release of inflammatory mediators such as nitric oxide (NO), PEG2 and other cytokines. RDL also reduced the phosphorylations of MAPK and NF-κB in TNF-α/IFN-γ-stimulated HaCaT cells. In vivo topical application of RDL to DNCB-induced AD mice significantly reduced the dorsal skin and ear thickness, clinical dermatitis severity, and mast cells. Treatment with RDL also markedly decreased the levels of serum IgE, IL-6 and the number of WBCs in the blood. CONCLUSION Our studies indicate that RDL inhibits the AD-like skin lesions by modulating skin inflammation. Consequently, these results suggest that RDL may be served as a possible alternative therapeutic treatment for skin disorder such as AD.

Pharmacokinetics and Biodistribution of Tacrolimus after Topical Administration: Implications for Vascularized Composite Allotransplantation. Pharm Res 2020; 37:222.

Abstract
AIM The high doses of oral tacrolimus (TAC) (1,2) necessary to prevent acute rejection (AR) after vascularized composite allotransplantation (VCA) are associated with systemic adverse effects. The skin is the most antigenic tissue in VCA and the primary target of AR. However, the short-term use of topical TAC (Protopic®), as an off-label adjunct to oral TAC, to treat AR episodes pro re nata (PRN), has yielded inconsistent results. There is lack of data on the pharmacokinetics and tissue distribution of topical TAC in VCA, that hampers our understanding of the reasons for unreliable efficacy. Toward this goal, we evaluated the ability of topical TAC to achieve high local tissue concentrations at the site of application with low systemic concentrations. MATERIALS AND METHODS We assessed the pharmacokinetics and tissue distribution of topical TAC (Protopic®, 0.03%) after single or repeated topical application in comparison to those after systemic delivery in rats. Animals received a single topical application of TAC ointment (Group 1) or an intravenous (IV) injection of TAC (Group 2) at a dose of 0.5 mg/kg. In another experiment, animals received daily topical application of TAC ointment (Group 3), or daily intraperitoneal (IP) injection of TAC (Group 4) at a dose of 0.5 mg/kg for 7 days. TAC concentrations in blood and tissues were analyzed by Liquid Chromatography-Mass Spectrometry (LC/MS-MS). RESULTS Following single topical administration, TAC was absorbed slowly with a Tmax of 4 h and an absolute bioavailability of 11%. The concentrations of TAC in skin and muscle were several folds higher than whole blood concentrations. Systemic levels remained subtherapeutic (< 3 ng/ml) with repeated once daily applications. CONCLUSION Topical application of TAC ointment (Protopic®, 0.03%) at a dose of 0.5 mg/kg/day provided high concentrations in the local tissues with low systemic exposure. Repeated topical administration of TAC is well tolerated with no local or systemic adverse effects. This study confirms the feasibility of topical application of TAC for site specific graft immunosuppression and enables future applications in VCA.

Abstract
Background: Tacrolimus is a new type immunosuppressant. The aim of this study was to evaluate the effectiveness of topical tacrolimus 0.1% ointment at 2 different frequencies in treating patients with exfoliative cheilitis.Methods: A total of 40 patients with exfoliative cheilitis were randomly divided into the QD group receiving topical tacrolimus 0.1% ointment once a day or the QOD group receiving topical tacrolimus 0.1% ointment once-two-day. Patients were also applied wet dressing of saline twice a day. The effectiveness of treatment was defined as the percentage of improvement in signs or symptoms.Results: 37 patients completed the 2-week treatment. And, a full set was analyzed. The effectiveness of topical tacrolimus 0.1% ointment for relief in objective sign and subjective symptom was 50% and 67.5%% in the QD group, respectively. For the QOD group, the effectiveness of sign and symptom relief was 50% and 73.5%. There was no significant difference of effectiveness between application topical tacrolimus once a day and once 2 days.Conclusion: Our data suggested that application of topical tacrolimus 0.1% ointment once a day and once 2 days had similar clinical effectiveness for sign and symptom relief in patients with exfoliative cheilitis.

Abstract
Twelve new resorcylic acid lactones (RALs) including three new 16-membered RALs (1a, 1b and 2), eight new 14-membered RALs (3-10), and one new 12-membered RAL (11), along with five known 14-membered RALs (12-16), were identified from the fermentation of the soil-derived fungus Ilyonectria sp. sb65. Their structures were established by detailed analyses of 1D and 2D NMR, HRESIMS, and X-ray diffraction crystallography. All new compounds were evaluated for their cytotoxic effects against three human cancer cell lines, along with their potential as TRAIL sensitizers in TRAIL-resistant A549 human lung adenocarcinoma cells and their in vitro immunosuppressive effects against ConA-induced T-cell and LPS-induced B-cell proliferation.

Abstract
AIM We collected evidence and safety data for topical tacrolimus in small children with atopic dermatitis (AD) and compared the usage with topical corticosteroid. METHODS This was an interim analysis of 75 patients (55% female) at 1 year of an ongoing 3-year randomised open-label comparative follow-up study of topical tacrolimus vs corticosteroid treatment. One- to three-year-old children with moderate-to-severe eczema referred to the Skin and Allergy Hospital in Helsinki, Finland, were enrolled. RESULTS Efficacy parameters, the Eczema Area and Severity Index (EASI), Investigator's Global Assessment (IGA), transepidermal water loss (TEWL), eczema area, serum total immunoglobulin E (IgE) and the blood eosinophil count, showed improvement in both groups during the study. However, patients with signs of early sensitisation at baseline (elevated serum total IgE, elevated eosinophil count, positive prick tests or specific IgEs to aero or food allergens) had statistically significantly lower TEWL at the eczema site and a smaller eczema area at 12 months in the tacrolimus group. No severe adverse effects were seen during the treatment. CONCLUSION Children with AD and signs of early sensitisation appeared to benefit more from early tacrolimus than corticosteroid treatment. Small children may need stronger but nevertheless safe ointment options when treating moderate-to-severe AD.

Abstract
Atopic dermatitis (AD) is the most common pediatric chronic inflammatory skin disease in North America, often involving complex treatment regimens and impairing the quality of life of affected children and their families. Two topical calcineurin inhibitors (TCIs) have been available for the treatment of AD in pediatric patients for more than 15 years, and they continue to represent an important steroid-sparing option for the management of AD. Despite the large body of evidence and extensive clinical experience with these agents, there remain concerns among parents and clinicians regarding the long-term safety of this class of therapy, particularly with respect to the boxed warning about the potential risk of lymphoma and malignancy associated with TCIs. Concerns about burning or stinging with initial applications are also common. This review examines the literature on the clinical effectiveness of TCIs, with a focus on the pivotal research that supports the efficacy of these agents, and the reassuring body of evidence supporting their long-term safety in pediatric patients. Practical recommendations for maximizing the utility of TCIs in pediatric patients, including discussion points to address with parents, are offered.

Abstract
The topical calcineurin inhibitors (TCIs), tacrolimus (Protopic) and pimecrolimus (Elidel), were approved in the early 2000s and were widely used as a nonsteroid treatment for atopic dermatitis (AD) in adult and pediatric populations. In 2005, the addition of a boxed warning was mandated for TCIs based on a potential risk of malignancy, and there was subsequently a substantial decline in their use. Since then, evidence has mounted to support the safety of this class of medications and suggests that the increased risk of malignancy remains theoretical. This review aims to dispel some of the common myths surrounding the safety of TCIs by evaluating the key evidence regarding their safety and tolerability in adult and pediatric populations. Four major themes are addressed in a practical question-and-answer format: the risk of harm associated with TCIs including common and serious adverse events; warnings and precautions for their use including the risk of systemic absorption, immunosuppression, and malignancy; the comparative safety of TCIs; and suggestions for counselling patients about the risk of harm with TCIs. Based on the available evidence, international professional dermatological organizations and regulatory authorities have concluded that the benefits of TCIs outweigh their potential risks when used in the appropriate patient populations for the recommended duration of time.

Abstract
BACKGROUND Treatment of atopic dermatitis and psoriasis in children is difficult due to lack of standardized treatment guidelines and few FDA-approved treatment options. Treatments approved for adults may be used off-label in pediatric patients. OBJECTIVE This review evaluates the topical and oral treatment options available, including off-label uses, and provides a basic therapeutic guideline for pediatric atopic dermatitis and psoriasis. METHODS A PubMed review of topical and systemic treatments for pediatric psoriasis and atopic dermatitis with information regarding age, efficacy, dosing, contra-indications, adverse events, and off-label treatments. RESULTS The search identified seven topical and five systemic treatments that are routinely employed to treat pediatric atopic dermatitis and psoriasis. LIMITATIONS Standardized guidelines regarding treatment choice, dosing, and long-term safety are scarce. Reviews may be subject to ascertainment bias. CONCLUSIONS Current treatment guidelines are based on clinical experience and expert advice with few treatments officially approved for atopic dermatitis and psoriasis in children.

Abstract
Atopic dermatitis (AD) is a frequent skin complication that is caused by unknown reasons. KHU-ATO-JIN-D (KAJD) is a new drug aimed at AD composed of a mixture of extracts from six plants known to have anti-inflammatory and antiallergic effects. This study investigated whether KAJD alleviates 2,4-dinitrochlorobenzene (DNCB)-induced AD in BALB/c mice and several immune cell types. We applied KAJD to DNCB-induced AD-like skin lesions in BALB/c mice, phorbol myristate acetate/ionomycin-stimulated human mast cells (HMC-1), and lipopolysaccharide (LPS)-stimulated macrophages and splenocytes. Histological, ELISA, PCR, and Western blot experiments were performed. The application of KAJD significantly attenuated the lesion severity and skin thickness and inhibited the infiltration of inflammatory cells, mast cells, and CD4+ T cells into the sensitized skin of mice. Reduced leukocyte numbers and proinflammatory cytokine and IgE levels were also observed in the sera of KAJD-treated mice. Moreover, in vitro studies demonstrated that KAJD treatment reduced the LPS-induced expression of proinflammatory cytokines and nitric oxide (NO) production in RAW 264.7 cells. The regulation of IL-4 and IL-6 mRNA and MAPK pathways was also detected in agonist-induced isolated splenocytes and HMC-1 cells by the addition of KAJD. Taken together, our results demonstrate that KAJD inhibits the development of DNCB-induced AD in BALB/c mice and in several immune cell types, suggesting that KAJD might be a useful therapeutic drug for the treatment of AD.

Abstract
Kaposiform hemangioendothelioma (KHE) and tufted angioma (TA) are rare infiltrative vascular tumors. Currently, no standard treatment regimens exist for KHE/TA. The purpose of our study was to evaluate the efficacy and safety of topical application of tacrolimus for superficial KHE/TA. We examined six patients with superficial KHE/TA. All patients were treated with tacrolimus 0.1% ointment twice daily for at least 12 months. The response rate was 100%, including three nearly complete remissions. Only one patient experienced local pruritus during treatment. The data constituted an intriguing rationale for clinical trials of topical tacrolimus in the treatment of superficial KHE/TA.

Abstract
This study is aimed to further investigate the anti-atopic dermatitis (AD) activities of dehydroxymethylepoxyquinomicin (DHMEQ) ointment and compare its effect with that of tacrolimus ointment based on the previous study that DHMEQ improves AD-like lesions. AD were induced by 2,4-dinitroclilorobenzene/oxazolone (DNCB/OX) repeatedly on the ears of BABL/C mice while medical tape was additionally used to disrupt stratum corneum in order to exacerbate the lesions. The mice were randomly divided into groups, which are normal, vehicle, DHMEQ (0.1%) and tacrolimus (0.1%). Those in the last two groups were externally applied with DHMEQ ointment and tacrolimus ointment, respectively. The results showed that both of them significantly improved dermatitis symptoms of DNCB/OX-induced AD-like lesions, such as redness, itching, weeping, scaling and thickening of the skin, while reducing epidermis thickness, dermis thickness and the number of mast cells as well, which were examined histopathologically. In contrast with DHMEQ, tacrolimus led to a significant decrease in body weight after long-term application. Both DHMEQ and tacrolimus suppress DNCB-induced increase of serum total IgE and attenuate expression of inflammatory factors IL-4, IL-6, IL-13, IL-1β and interferon (IFN)-γ in the disrupted ear tissues. On the other hand, the mice applied with tacrolimus became obviously irritable, jumping up and down, and inflammatory exudation on the lesioned-skin surface of the mice was remarkably observed. Contrary to the side effects made by tacrolimus, DHMEQ didn't cause any adverse stimulus response. As a conclusion, DHMEQ is safer, milder and more suitable for long-term use than tacrolimus for the treatment of AD-like lesions.

Abstract
FK506 (tacrolimus) is an immunosuppressant widely used as an ointment in the treatment of atopic dermatitis. However, local application of FK506 can evoke burning sensations in atopic dermatitis patients, and its mechanisms are unknown. In this study, we found that FK506 activates transient receptor potential ankyrin 1 (TRPA1) channels. In Ca2+-imaging experiments, increases in intracellular Ca2+ concentrations ([Ca2+]i) by FK506 were observed in HEK293T cells expressing hTRPA1 or hTRPM8. FK506-induced currents were observed in HEK293T cells expressing hTRPA1 or mTRPA1, but less or not at all in cells expressing hTRPV1 or hTRPM8 using a patch-clamp technique. FK506 also evoked single-channel opening of hTRPA1 in an inside-out configuration. FK506-induced [Ca2+]i increases were also observed in TRPA1-expressing mouse primary sensory neurons. Furthermore, injection of FK506 evoked licking or biting behaviors and these behaviors were almost abolished in TRPA1 knockout mice. These results indicate that FK506 might cause pain sensations through TRPA1 activation.

Abstract
INTRODUCTION Atopic dermatitis (AD) is perhaps the most common inflammatory skin disorder worldwide, with an increasing incidence in developed countries. The mainstay treatment for patients with AD is topical therapies, which are used not only by the mild patients but also by the moderate-to-severe patients, in conjunction with systemic treatment. While topical steroids and calcineurin antagonists are widely used, these are associated with long-term cutaneous adverse effects (AEs) or a black box warning, preventing their chronic use. Areas covered: The aim of this review is to provide a comprehensive overview of new and upcoming topical therapies currently in development and undergoing clinical trials, as well as their safety and efficacy profiles, and discuss current topicals used in the management of AD. Expert opinion: AD is a heterogeneous disease with complex pathophysiology. Treatments available to date for AD provide disease control; however, patients struggle to find an optimized therapeutic regimen they may use long term and without severe effects. Novel therapies are currently under investigation, with the hope of shifting the paradigm of AD management from symptom control to disease eradication.

Abstract
INTRODUCTION Treatment guidelines endorse a variety of strategies for atopic dermatitis (AD) which may vary from published data and clinical practice patterns. The objective of this review was to quantify the volume of available medical literature supporting pediatric AD treatments and compare these patterns to those recommended by published guidelines and/or clinical practice patterns. METHODS Searches of Embase (2005-2016) and abstracts from selected meetings (2014-2016) related to AD treatment in patients younger than 17 years of age yielded references that were assessed by study design, primary treatment, age groups, and AD severity. RESULTS Published literature partially supports clinical guidelines, with emollients and topical medications being the most investigated. There were disproportionately more publications for topical calcineurin inhibitors (TCI) compared with topical corticosteroids (TCS); however, the search interval may have biased the results toward treatments approved near the beginning of the time frame. In contrast, publications documenting clinical practice patterns reflect greater use of emollients and TCS (over TCI), as well as systemic corticosteroids. Data is relatively limited for long-term and combination treatment, treatment of severe AD, and patients younger than 2 years of age, and completely lacking for systemic corticosteroids. CONCLUSION This scoping review demonstrates that available medical literature largely supports published guidelines for topical therapy; however, clinical practice patterns are less aligned. There is a lack of data for older, more frequently used generic treatments, including oral antihistamines, oral antibiotics, and systemic corticosteroids. Overall, literature is lacking for long-term treatment, treatment for patients younger than 2 years of age, and for systemic treatment for severe disease. FUNDING Regeneron Pharmaceuticals Inc.

Abstract
Atopic dermatitis is one of the most common skin disorders in the developed world, affecting up to 20% of children and 1% to 3% of adults. This review concisely explains the pathophysiology and epidemiology of atopic dermatitis, as well as potential challenges facing its successful treatment. Furthermore, mainstay topical treatment modalities are evaluated, such as emollients, topical corticosteroids, and topical calcineurin inhibitors. The use of topical corticosteroids and topical calcineurin inhibitors in combination is discussed, as studies have indicated encouraging results. The proactive use of topical corticosteroids and topical calcineurin inhibitors is also investigated, in order to bring attention to a new possibility in long-term management of atopic dermatitis. Last, new and upcoming topical medications are described, including Janus kinase inhibitors, phosphodiesterase-4 inhibitors, and benvitimod. Although topical corticosteroids and topical calcineurin inhibitors can be very effective in the treatment of atopic dermatitis, it is important that practitioners are aware of mechanistically unique and new treatments for patients for whom more traditional topical therapies have failed. Overall, this review article hopes to serve as a comprehensive overview of currently available topical treatments for atopic dermatitis, while shedding light on new treatments coming in the future.

Abstract
Forsythia suspensa (F. suspensa) is a traditional medicine for treatment of inflammation. In this study, we evaluated the therapeutic effects of an ethanol extract from F. suspensa fruits on atopic dermatitis both in vivo and in vitro. We investigated the inhibitory effects of F. suspensa extract on the development of atopic dermatitis-like skin lesions in an NC/Nga mouse model exposed to Dermatophagoides farinae crude extract. Topical application of F. suspensa extract to the mice attenuated the atopic dermatitis symptoms, including increased dermatitis severity score, ear thickness, infiltration of inflammatory cells in the skin lesions, serum levels of IgE, TNF-α, and histamine, and expression of chemokines, cytokines, and adhesion molecules in ear tissue. In addition, F. suspensa extract inhibited the production of chemokines in TNF-α/IFN-γ-activated human keratinocytes. High-performance liquid chromatography analysis of FSE revealed the presence of four chemical constituents (forsythiaside, phillyrin, pinoresinol, and phylligenin). These compounds inhibited the production of chemokines in TNF-α/IFN-γ-activated human keratinocytes. These results suggest that the F. suspensa might be a useful candidate for treating allergic skin inflammatory disorders.

Abstract
This review presents the results of international and Russian clinical studies conducted to assess the efficacy and safety of topical calcineurin inhibitors (TCIs) for the treatment of atopic dermatitis. The main mechanisms of action of TCIs are described. The authors demonstrate the advantages of Tacrolimus belonging to the TCI group. Due to the hydrophilic drug form and pharmacoeconomic index promoting compliance with treatment, it is possible to consider the new drug Tacropic (0.1% and 0.03% Tacrolimus ointments) as the optimum topical drug for the treatment of moderate to severe and severe forms of atopic dermatitis in adults and children.

Abstract
BACKGROUND Many clinicians have concerns about the safety of atopic dermatitis (AD) treatments, particularly in children requiring long-term daily maintenance therapy. Topical corticosteroids (TCS) have been widely used for >5 decades. Long-term TCS monotherapy has been associated with adverse cutaneous effects including atrophy, rebound flares, and increased percutaneous absorption with potential for adverse systemic effects. Topical calcineurin inhibitors (TCIs), tacrolimus and pimecrolimus, available for 1-2 decades, are not associated with atrophy or increased percutaneous absorption after prolonged use and have much lower potential for systemic effects. However, since 2006 TCIs have carried a controversial Boxed Warning based on a theoretical risk of malignancy (eg, skin and lymphoma) that has limited TCI use for standard-of-care maintenance therapy. METHODS A comparative systematic search of PubMed was done for long-term (≥12 week) clinical trials of TCS or TCI treatment in patients <12 years with AD. Citations were reviewed for inclusion based on MeSH terms, abstracts, and relevant article text. Studies were excluded if they did not encompass subjects <12 years, or were <12 weeks' duration, retrospective, meta-analyses, or limited to anecdotal case reports. RESULTS Of 27 trials meeting criteria, 21 included 5825 pediatric patients treated with TCIs, and 6 included 1999 patients treated with TCS. TCS studies were limited to low- to mid-potency products, and all but one study lacked a vehicle control. Eight TCI studies were vehicle-controlled, and safety data were well reported, with ≤5 % of patients reporting discontinuation due to adverse effects (DAEs). Cutaneous and systemic adverse events (AEs) were similar in TCI and vehicle groups, with no reports of lymphoma. Safety data in TCS trials were less well reported. DAE incidence was addressed in just 2 trials, and systemic and cutaneous AEs were mostly unreported. CONCLUSIONS Data supporting long-term use of TCIs are robust, documenting safety and efficacy, while data supporting long-term TCS use are limited to low- to mid-potency products. Our review identifies a lack of information on the safety of commonly prescribed, long-term monotherapy with mid- to high-potency TCS in pediatric AD, and supports standard-of-care maintenance therapy with TCIs and intermittent use of low- to mid-potency TCS for flares.

Abstract
Tacrolimus (TAC), a non-steroidal anti-inflammatory and immunosuppressive agent, is used for the treatment of atopic dermatitis (AD) and skin immune diseases. TAC-loaded topical hydrogel formulations composed of carbomer, carnosine, transcutol P (diethylene glycol monoethyl ether) and humectant were prepared. For comparison, TAC-loaded topical cream-type formulations were also prepared and commercially available TAC ointment was used as a reference. A drug release study in vitro revealed that the total amount of TAC released from hydrogels over 24 h was approximately 30 times greater than that for the reference formulation. Compared to the reference ointment and creams, carbomer gel formulations showed higher skin permeation and retention of TAC (significantly different at p < 0.05), especially those with more than 10% of transcutol P. Therefore, carbomer gel formulations with sufficient levels of transcutol P are good candidates for skin delivery of TAC and have potential as therapeutic agents for the treatment of AD or immune skin disorders.

Abstract
Atopic eczema (AE) is a chronic, inflammatory skin disorder which usually develops in early childhood. In spite of intensive investigations, the causes of AE remain unclear, but are likely to be multifactorial in nature. Environmental factors or genetic-environmental interactions seem to play a key role in disease progression. Among various measures of AE managment, cutaneous hydration, which improves barrier function and relieve itchiness, may be helpful to reduce the need for topical steroid use and therefore should be used as a basic treatment. Avoiding aggravating factors is also a basic treatment of AE. Standard medical treatment with a pharmacologic approach may be necessary if basic treatment fails to control symptoms satisfactorily. Recently, more attention is given to a proactive therapeutic by regular intermittent application of low potency steroids or topical calcineurin inhibitors to prevent new flares. Furthermore, various targeted biologics are being introduced for AE control and are proposed as promising therapies. This paper provides a summary of the recent literature on the manangement of AE and a treatment guideline.

Abstract
Psoriasis is a potentially debilitating inflammatory dermatosis affecting 0.2%-4.8% of the population worldwide causing a significant occupational, personal or psychosocial morbidity to these patients for life. The basic aim of psoriasis therapy is to control the disease to maximum possible extent and improve the patient’s quality of life. Management of triggers for flare-ups, lifestyle modifications, and dietary supplements are often recommended. Intermittent or rotational therapy with frequent alterations in treatment options is usually needed to reduce toxicity of anti-psoriatic drugs in the absence of safer alternatives. Currently, several biological agents categorized as either T-cell targeted (e.g., Alefacept, Efalizumab) or cytokine modulating (e.g., Adalimumab, Infliximab, Etanercept) are available for treating severe psoriasis. However, their high cost is often precluding for most patients. The usefulness of systemic (methotrexate, cyclosporine, acitretin or several other therapeutic agents) or topical (tar, anthralin, corticosteroids or calcipotriol ointments, phototherapy with or without psoralens) therapies has been well established for the management of psoriasis. The literature is also replete with benefits of less used non-standard and unconventional treatment modalities (hydroxycarbamide, azathioprine, leflunomide, mycophenolate mofetil, isotretinoin, fumarates, topical calcineurin inhibitors, peroxisome proliferator-activated receptors agonists, statins, sulfasalazine, pentoxifylline, colchicine, grenz ray therapy, excimer laser, climatotherapy and balneophototherapy, peritoneal dialysis, tonsillectomy, ichthyotherapy, etc.). These can be used alternatively to treat psoriasis patients who have mild/minimal lesions, are intolerant to conventional drugs, have developed side effects or achieved recommended cumulative dose, where comorbidities pose unusual therapeutic challenges, or may be as intermittent, rotational or combination treatment alternatives.

Abstract
Broussonetia kazinoki Siebold. (B. kazinoki) has long been used in the manufacture of paper in Asian countries. Although B. kazinoki leaves (BK) have been employed in dermatological therapy, use of BK has not been tested in patients with atopic dermatitis (AD). Using Nc/Nga mice, which are genetically predisposed to develop AD-like skin lesions, we confirmed the efficacy of BK in AD treatment. BK extract was applied topically to Dermatophagoides farinae-induced AD-like lesions in Nc/Nga mice, and the effects were assessed both clinically and by measuring skin thickness on the back and ears. We measured the effects of BK extract on plasma levels of IgE and IL-4. We also measured the ability of BK extract to inhibit the secretion of hTARC in HaCaT cells after stimulation by TNF-α and IFN-γ. We found that BK extract significantly reduced ear and dorsal skin thickness and the clinical signs of AD, as well as significantly down-regulating the plasma levels of IgE and IL-4 (p<0.01 for each comparison). Moreover, 500 μg/mL of BK extract inhibited hTARC secretion in HaCaT cells by activated TNF-α/IFN-γ by about 87%. These findings suggest that topical application of BK extract has excellent potential in the treatment of AD.

Abstract
Group A beta-hemolytic streptococcus cause most vulvovaginal infections seen in prepubertal girls. Bacterial vaginosis is a common cause of abnormal vaginal discharge in women of childbearing age but is rare in children. Data are insufficient to suggest that bacterial vaginosis is an exclusively sexually transmitted disease. We report a 10-year-old girl with no history or suspicion of sexual abuse who developed bacterial vaginosis in the context of a lichen sclerosus being treated with tacrolimus ointment. Secondary bacterial infection in lichen sclerosus is uncommon. We speculate that the immunosuppressive effect of topical tacrolimus could have triggered the infection.

Abstract
Despite the increasing use of topical tacrolimus, there is little information about its effect on skin wound healing. To determine effects on acute cutaneous wound healing, two full-thickness skin wounds were imparted on the backs of 45 hairless mice, which were then divided into vehicle-, topical tacrolimus- and topical steroid-treated group. Each drug was topically applied once daily. The wound area was assessed by using dermoscopic images every two days after wounding. At 3, 7 and 11 days after wounding, 10 wounds in each group were collected for semi-quantitative analysis of histological features including re-epithelialization, polymorphonuclear leucocytes, fibroblasts and collagen. We also checked the mRNA expression levels of EGF, TGF-β, TNF-α and IL-1α. While topical application of clobetasol propionate was found to delay re-epithelialization and infiltration of polymorphonuclear leucocyte, topical treatment with tacrolimus showed patterns similar to that of the vehicle. In the tacrolimus-treated group, mRNA expression levels of IL-1α and TGF-β were slightly decreased, while the others were similar with the vehicle-treated group. Unlike steroid, topical tacrolimus, therefore, did not disturb the wound healing process in a murine skin wound model.

Abstract
Topical calcineurin inhibitors (TCIs), commercially available since 2000–2001, are the first and only topical medications approved for chronic treatment of atopic dermatitis (AD) in pediatric patients and remain a welcomed alternative to topical corticosteroids. In January 2006, the US Food and Drug Administration (FDA) issued a boxed warning requirement based on a theoretical risk of malignancy (including lymphoma) with TCI use. However, in the years since, analyses of epidemiologic and clinical data have failed to demonstrate a causal relationship between TCI use and malignancy or lymphoma risk, especially for pimecrolimus cream. In fact, the observed number of malignancies and lymphomas observed both in post-marketing surveillance and reported to the FDA using its adverse events reporting system is much lower among TCI-exposed patients than the expected number for the general population. Furthermore, among children enrolled in post-marketing pediatric registry studies for both tacrolimus and pimecrolimus followed for up to 5.5 years [10,724 patient-years (PY)] or 6.5 years (16,219 PY), respectively, the observed number of malignancies and lymphomas is very low and similar to the number expected for a sample of similar size in the general population. In addition to reporting these comparative malignancy and lymphoma data, this article provides a historical overview of the boxed warning requirement and critically evaluates the preclinical, clinical, and epidemiological evidence that has thus far failed to substantiate a relationship between TCI use and malignancy. The authors also provide practical clinical advice for optimizing AD management and patient care in the context of the boxed warning.

Abstract
We examined whether Angelicae Dahuricae Radix (AR) suppresses the development of atopic dermatitis (AD)-like skin lesions induced by Dermatophagoides farinae in NC/Nga mice. To investigate the effect of AR, we measured the AD severity score, measured plasma levels of IgE and histamine, and performed histological analysis in NC/Nga mice. We also confirmed the anti-inflammatory effects of AR by measuring TARC/CCL17 production from LPS-treated RAW 264.7 cells and mRNA levels of TARC and MDC/CCL22 in TNF-α/IFN-γ-treated HaCaT cells. 10 mg/day of AR extract was applied for 4 weeks to NC/Nga mice. Both the AR extract and 0.1% tacrolimus suppressed the development of AD-like skin lesions and reduced dermatitis scores of the back and ear skin. AR extracts caused an inhibition of histological changes induced by repeated application of D. farinae and a reduction of IgE and histamine levels in plasma (P < 0.05). Furthermore, NO production in LPS-treated RAW 264.7 cells was diminished in a dose-dependent manner, and hTARC production and TARC and MDC mRNA levels in TNF-α/IFN-γ-treated HaCaT cells were diminished by AR. The inhibitory effect of AR on NO, TARC and MDC production may be associated with the suppression of AD-like skin lesions in D. farinae-induced NC/Nga mice.

Abstract
AIMS To examine the efficacy of tacrolimus ophthalmic suspension 0.1% in treating severe allergic conjunctivitis. METHODS This was a multicenter, randomized, double-masked, placebo-controlled clinical trial. Fifty-six patients with severe allergic conjunctivitis in whom topical antiallergic agents and corticosteroids had been ineffective were randomized to tacrolimus or placebo treatment. Patients were treated either with tacrolimus or placebo twice-daily for 4 weeks. Severity of objective signs in palpebral and bulbar conjunctiva, limbus, and corneal involvement was assessed using 4 grades. Seven subjective symptoms were evaluated by visual analog scale (VAS) assessment. The primary efficacy endpoint was change in the total score of objective signs at the end of treatment. The secondary efficacy endpoints included change in the score for each objective sign and change in the VAS for each subjective symptom. Safety was assessed based on the severity and the incidence of adverse events. RESULTS Mean change from baseline in total score for objective signs was significantly greater in the tacrolimus (-5.6 + or - 5.1) than in the placebo group (-0.1 + or - 4.5; P < 0.001). Tacrolimus significantly improved giant papillae (P = 0.001) and corneal involvement (P = 0.005). Five subjective symptoms (itching, discharge, hyperemia, lacrimation, and foreign body sensation) were significantly better in the tacrolimus than in the placebo group. The most frequent treatment-related adverse event in the tacrolimus group was mild ocular irritation upon topical instillation, which was well-tolerated. CONCLUSION Tacrolimus ophthalmic suspension 0.1% is effective in treating severe allergic conjunctivitis.

Abstract
Atopic dermatitis (AD) is the most common skin disease in children, and its prevalence is increasing. It is a chronic disorder, characterized by intermittent flares and phases of remission. Treatment regimens often require multiple therapies. These can vary between patients, and in an individual patient, depending on the state of disease. The traditional treatment for AD flares is topical corticosteroids, which are fast acting and effective for relief of symptoms, but may cause adverse effects, including those resulting from systemic absorption, particularly in children. Topical calcineurin inhibitors (TCIs) are alternative treatments for AD. Tacrolimus ointment, a TCI, is approved for patients aged 2 years and older. Multiple studies have shown that tacrolimus is effective for short-term relief of symptoms in pediatric patients with AD. Long-term trials have demonstrated that the effectiveness of tacrolimus is maintained for up to 4 years in children. Additional studies have revealed that long-term intermittent use of tacrolimus as part of maintenance therapy can prevent AD flares. Tacrolimus has a low potential for systemic accumulation, and analysis of long-term studies indicates that it has a good safety profile. Treatment with tacrolimus, alone or in combination with topical corticosteroids for acute flares, may be a useful option for long-term management of AD in pediatric patients.

Abstract
In this article there were regarded the most frequent side effects that appear in the patients who have been treated with topical tacrolimus, and the association between topical tacrolimus and the development of tumors is unfolded. The irritation in the site of application of the tacrolimus can manifiest as pruritus, sensation of burning and/or eritema located to the area of the application. It is the most frequent side effect, independently of the duration of the study. The cutaneous infections, especially the viral ones, tend to be more numerous in patients with atopic dermatitis that receive topic tacrolimus. After reviewing the medical literature one concludes that nowadays there doesn t exist scientific evidence of an increase of skin cancer, lymphomas or systemic immunosuppression in those patients that use or have used topical tacrolimus. Nevertheless, it is not possible to exclude the possibility that there appear cutaneous and/or systemic long-term side effects.

Abstract
Topical treatment with tacrolimus is more effective than the placebo and the low potency corticosteroids in the treatment of atopic dermatitis (AD) in both adults and children while it has a similar potency as some topical corticosteroids of medium potency. Since it was put on the market, more evidence has been accumulating to make our previous statements and it has been demonstrated to have greater effectivity than topical pimecrolimus and oral cyclosporine. It is a safe drug and its side effects are of little importance. Specifically no side effects have been demonstrated due to its systemic absorption nor has there been any increase in skin infections. The most frequent side effect is burning sensation or increased pruritus in the area where the product is applied. It is more frequent if the lesions treated are very acute and is generally transitory, not causing the treatment to be discontinued. Furthermore, with the current information, it cannot be associated to an increase of any type of neoplasms.

Abstract
Objective: To evaluate the available treatment options for pediatric atopic dermatitis, Data Sources: A literature review was performed in MEDLINE (1950-February 2010) using the key word atopic dermatitis. The references identified were evaluated in comparative treatment. The references included in this review were limited to studies conducted in children less than 18 years of age and written in the English language. Study Selection and Data Extraction: All of the literature retrieved that was published within the last 5 years (2005-2010) was included in this review. Other pertinent articles published prior to 2005 were also included. Data Synthesis: Atopic dermatitis is a chronic inflammatory skin disorder that usually begins during infancy. Potential causes include irritants such as soap and detergents, food allergens, contact allergens, and skin infections. Emollients, moisturizing agents that inhibit water loss and provide a protective coating, are recommended in all patients with atopic dermatitis. Additionally, emollients may reduce the need to use topical corticosteroids. Patients receiving desanide 0.05% plus an emollient achieved significant reductions in severity scores compared to those receiving desonide 0.05% as monotherapy (80% vs 70%; p < 0.01). Topical calcineurin inhibitors are not recommended as first-line therapy in pediatric patients with atopic dermatitis; however, their use in children above 2 years of age who fail to respond to topical corticosteroids may be considered. Conclusions: Emollients are recommended in pediatric patients with a diagnosis of atopic dermatitis regardless of symptoms. Topical corticosteroids reduce the inflammation and pruritus associated with atopic dermatitis and are available in several formulations and strengths. Calcineurin inhibitors may be an alternative in children older than 2 years of age who do not respond to topical corticosteroids,

Abstract
Tacrolimus 0.03% ointment is licensed for second-line treatment of children with atopic dermatitis (AD). Although data are available from clinical trials, no study has enrolled only second-line patients. This double-blind, non-inferiority study compared tacrolimus 0.03% and fluticasone 0.005% ointments in children with moderate-to-severe AD, who had responded insufficiently to conventional therapies. Children (aged 2-15 yr) were randomized to tacrolimus ointment (n = 240) or fluticasone ointment (n = 239), twice daily until clearance or for a maximum of 3 wk and, if lesions remained, once daily for up to 3 wk further. Primary end-point was week 3 response rate (improvement of >or=60% in modified Eczema Area and Severity Index and not withdrawn for lack of efficacy). Secondary end-points included pruritus and sleep quality, global assessment of clinical response, incidence of new flares and safety. Response rates were 86.3% with tacrolimus ointment and 91.5% with fluticasone. Lower limit of the 95% confidence interval was -11.8%, exceeding the non-inferiority limit of -15% and meeting the primary end-point. Moderate or better improvement on the physicians' global assessment occurred in 93.6% and 92.4% of patients in the tacrolimus ointment and fluticasone arms, respectively, while median pruritus scores improved by 84.0% and 91.5%. Sleep quality improved by approximately 92% in both treatment arms. After day 21, new flare-up occurred in 5.5% and 11.3% of patients receiving tacrolimus ointment and fluticasone, respectively; mean times to new flares were 6.5 +/- 5.0 and 8.6 +/- 5.2 days. Adverse events were similar between the two arms, with the exception of application-site skin burning sensation in the tacrolimus ointment group. In conclusion, efficacy of tacrolimus 0.03% ointment as second-line treatment was not inferior to that of fluticasone 0.005% ointment, with similar benefits on global disease improvement and quality of sleep.
