Comparing the effects of proactive treatment with tacrolimus ointment and mometasone furoate on the epidermal barrier structure and ceramide levels of patients with atopic dermatitis

Efficacy and safety of self-made WenyangJianpi-qushi Decoction combined with mometasone furoate cream in the treatment of atopic dermatitis of spleen deficiency and dampness accumulation type

Introduction: This work was to explore the efficacy and safety of self-made WenyangJianpi-qushi Decoction plus mometasone furoate cream in atopic dermatitis (AD) of spleen deficiency and dampness accumulation type. Material and method: 120 patients with this kind of atopic dermatitis were grouped: The Observation group (disease health education + basic treatment + mometasone furoate cream + self-made Decoction) and The Control group (disease health education + basic treatment + mometasone furoate cream), 60 cases in each group. The SCORAD score, serum IgE level, peripheral blood eosinophils, adverse events, recurrence rate, and total effective rate after treatment were observed.Result: Through treatment, SCORAD score of the observation group (29.96 ± 2.88) was lower as against controls (36.04 ± 3.12), p < 0.05. Through treatment, the peripheral blood eosinophil count in the observation group was (311.26 ± 50.19) 106/L, which was lower than (582.71 ± 54.75) 106/L in controls; the serum lgE of the observation group was (712.44 ± 93.32) IU/mL, which was lower than the controls (890.12 ± 81.25) IU/mL, p < 0.05. The Observation group (56/60, 93.33%) demonstrated superior total effective rate to the controls (34/60, 56.67%); The recurrence rate of the observation group was 4/60 (6.67%), which was lower than the controls 16/60 (26.67%), p < 0.05.Conclusion: Self-made WenyangJianpi-qushi Decoction plus mometasone furoate cream to treat atopic dermatitis of spleen deficiency and dampness accumulation type has significant efficacy and good safety.

Topical treatments for atopic dermatitis (eczema): Systematic review and network meta-analysis of randomized trials

BACKGROUND

Atopic dermatitis (AD) is a common skin condition with multiple topical treatment options, but uncertain comparative effects.

OBJECTIVE

We sought to systematically synthesize the benefits and harms of AD prescription topical treatments.

METHODS

For the 2023 American Academy of Allergy, Asthma & Immunology and American College of Allergy, Asthma, and Immunology Joint Task Force on Practice Parameters AD guidelines, we searched MEDLINE, EMBASE, CENTRAL, CINAHL, LILACS, ICTRP, and GREAT databases to September 5, 2022, for randomized trials addressing AD topical treatments. Paired reviewers independently screened records, extracted data, and assessed risk of bias. Random-effects network meta-analyses addressed AD severity, itch, sleep, AD-related quality of life, flares, and harms. The Grading of Recommendations Assessment, Development and Evaluation approach informed certainty of evidence ratings. We classified topical corticosteroids (TCS) using 7 groups-group 1 being most potent. This review is registered in the Open Science Framework (https://osf.io/q5m6s).

RESULTS

The 219 included trials (43,123 patients) evaluated 68 interventions. With high-certainty evidence, pimecrolimus improved 6 of 7 outcomes-among the best for 2; high-dose tacrolimus (0.1%) improved 5-among the best for 2; low-dose tacrolimus (0.03%) improved 5-among the best for 1. With moderate- to high-certainty evidence, group 5 TCS improved 6-among the best for 3; group 4 TCS and delgocitinib improved 4-among the best for 2; ruxolitinib improved 4-among the best for 1; group 1 TCS improved 3-among the best for 2. These interventions did not increase harm. Crisaborole and difamilast were intermediately effective, but with uncertain harm. Topical antibiotics alone or in combination may be among the least effective. To maintain AD control, group 5 TCS were among the most effective, followed by tacrolimus and pimecrolimus.

CONCLUSIONS

For individuals with AD, pimecrolimus, tacrolimus, and moderate-potency TCS are among the most effective in improving and maintaining multiple AD outcomes. Topical antibiotics may be among the least effective.

The Pathogenic and Therapeutic Implications of Ceramide Abnormalities in Atopic Dermatitis

Ceramides play an essential role in forming a permeability barrier in the skin. Atopic dermatitis (AD) is a common chronic skin disease associated with skin barrier dysfunction and immunological abnormalities. In patients with AD, the amount and composition of ceramides in the stratum corneum are altered. This suggests that ceramide abnormalities are involved in the pathogenesis of AD. The mechanism underlying lipid abnormalities in AD has not yet been fully elucidated, but the involvement of Th2 and Th1 cytokines is implicated. Ceramide-dominant emollients have beneficial effects on skin barrier function; thus, they have been approved as an adjunctive barrier repair agent for AD. This review summarizes the current understanding of the mechanisms of ceramide abnormalities in AD. Furthermore, the potential therapeutic approaches for correcting ceramide abnormalities in AD are discussed.

Clinical, patient and estimated cost benefits of proactive management versus reactive management with calcipotriol/betamethasone dipropionate foam for the treatment of plaque psoriasis in Finland

BACKGROUND

Proactive management of plaque psoriasis with twice-weekly topical calcipotriol/betamethasone dipropionate (Cal/BD) foam has a demonstrated clinical benefit in preventing disease relapse compared to reactive management, where Cal/BD foam is only given as rescue therapy once-daily for four weeks after relapse. The impact of proactive management with Cal/BD foam on a wider range of clinical responses is not yet known, nor is its potential cost-effectiveness in the healthcare system of Finland.

METHODS

This study involved a post-hoc analysis exploring the clinical and patient-reported benefits of proactive versus reactive management with Cal/BD foam observed in the PSO-LONG trial (NCT02899962). A range of response criteria based on modified psoriasis area and severity index (mPASI) and dermatology life quality index (DLQI) were analyzed, and the cost-effectiveness of proactive versus reactive management was estimated in a Finnish healthcare setting.

RESULTS AND CONCLUSION

The analysis found a consistent clinical benefit of proactive management compared to reactive management on all response criteria, and a markedly lower cost-per-responder for the response criteria of mPASI 75, mPASI ≤ 2 and DLQ1 ≤ 1. The analysis was robust to sensitivity analyses on key inputs and demonstrates the cost and clinical benefits of proactive over reactive management of plaque psoriasis with Cal/BD foam in the Finnish healthcare setting.

Multi parametric biophysical assessment of treatment effects on xerotic skin

Background

Topical moisturizing products are widely used to alleviate the problems associated with xerotic skin. Their use affects many properties of the stratum corneum (SC) in a complex and interrelated manner. The range of measurement techniques available to the researcher has increased in recent years. However, few studies have looked for correlations between the different techniques for assessing how aspects of xerotic skin change over time as a result of topical moisturizer usage.

Objectives

A 3‐week in vivo study using an oil‐in‐water based moisturizing product and an untreated site was conducted to determine the clinical significance of and any correlations between a range of different approaches for the measurement of skin lipid content and also skin hydration and visual grading of dry skin.

Methods

A range of traditional and more recently developed skin measurement techniques have been used to examine a variety of SC properties in normal and xerotic skin during topical moisturizer usage.

Results

In vivo confocal Raman spectroscopy and analysis of SC lipids from tape strips both showed an increase in SC lipid level and organization after 3 weeks of moisturizer usage on xerotic skin. Hydration, measured both optically and electrically, also increased and skin barrier function improved, with strong correlations between the different measures of dryness being observed.

Conclusions

Strong correlations were observed between the skin measurements for lipid assessment and skin hydration with regard to the assessment of xerotic skin, providing valuable new information for future in vivo clinical research into dry and atopic skin.
