The human epidermis has a characteristic lipidic composition in the stratum corneum, where ceramides play a crucial role in the skin barrier homeostasis and in water-holding capacity. Several skin diseases, such as atopic dermatitis and psoriasis, exhibit a dysfunction in the lipid barrier with altered ceramide levels and increased loss of transepidermal water. Glucocorticoids are normally employed in the therapeutical management of these pathologies. However, they have shown a poor safety profile and reduced treatment efficiency. The main objective of this review is to, within the framework of the limitations of the currently available therapeutical approaches, establish the relevance of nanocarriers as a safe and efficient delivery strategy for glucocorticoids and ceramides in the topical treatment of skin disorders with barrier impairment.

Background:Atopic dermatitis (AD) is a common chronic inflammatory skin disorder that induces several symptoms including pruritus and dryness, and is often associated with secondary cutaneous infections. AD is considered to be one of the most prevalent and studied skin diseases yet poorly understood, and its pathophysiology remains obscure. Even though other skin diseases (such as psoriasis) share the same pathologic factor -skin barrier defect - with atopic dermatitis, patients diagnosed with those diseases don't suffer infectious exacerbations like atopic patients do. Aim: Although many international researches have already discussed the relationship between staphylococcus aureus and AD, no studies about this subject in the Arabic region was documented. The aim of our study is to compare staphylococcus aureus colonization rates and densities between atopic dermatitis patients and non-atopic subjects, and to relate the colonization to the severity and duration of the disease. Materials and methods: This observational analytic study included 200 participants (99 diagnosed with atopic dermatitis and 101 control subjects without atopic dermatitis); nasal and skin swabs (lesional and non-lesional) were collected from patients, while nasal and only normal skin swabs were collected from controls. Positive swabs were assessed to determine the density of colonization. Results: 57.6% of patients had nasal colonization, 56.6% had lesional colonization and 30.3% had normal skin colonization. Nasal colonization rates and densities were higher in the patients group. We detected a correlation between colonization and severity of eczema, but no correlation between colonization and duration of the disease was detected. Conclusion: The high rates and densities of staphylococcus aureus colonization in lesional skin of atopic dermatitis patients point out the role of these organisms in the pathophysiology of the disease, put antibiotics on the treatment list of atopic dermatitis and explain infectious features in AD exacerbations.

Atopic dermatitis and psoriasis are common chronic dermatosis characterized by prolonged recurrent course. Depending on the severity of the disease topical and systemic treatment are applied. Keratoplastic agents play an important role in treatment of skin diseases. These agents include Naftalan Cream 30%, which significantly improves the skin condition. The results of treatment of 10 patients with atopic dermatitis and 10 patients with psoriasis vulgaris Naftalan cream 30% are presented.

Antimicrobial and immunomodulatory peptides (AMPs) are considered as the key players in the maintenance of skin barrier functions. Here, we developed a novel approach for the examination of AMPs in the outermost layer of the epidermis, namely stratum corneum (SC). The SC sample collection by tape stripping was coupled with detection by highly specific and sensitive parallel reaction monitoring (PRM)-based mass spectrometry. We found that hexane-free processing of SC samples produced higher protein yield compared to hexane-based extraction. Of the 18 investigated peptides, 9 could be detected either in healthy or in inflamed skin specimens. Regarding the amount of S100A8, LCN2, LACRT and LYZ significant topographical differences were described among gland poor (GP), sebaceous gland rich (SGR) and apocrine gland rich (AGR) healthy skin regions. We applied a minimally invasive, reproducible approach for sampling, which can be assessed for research and diagnostic purposes and for monitoring the effectiveness of therapies in skin diseases.

Atopic dermatitis (AD) is a chronic pruritic skin disorder affecting many people especially young children. It is a disease caused by the combination of genetic predisposition, immune dysregulation, and skin barrier defect. In recent years, emerging evidence suggests oxidative stress may play an important role in many skin diseases and skin aging, possibly including AD. In this review, we give an update on scientific progress linking oxidative stress to AD and discuss future treatment strategies for better disease control and improved quality of life for AD patients.
