The role of phosphodiesterase 4 in the pathophysiology of atopic dermatitis and the perspective for its inhibition.

Atopic dermatitis (AD) is a highly prevalent, chronic inflammatory skin disease that affects children and adults. The pathophysiology of AD is complex and involves skin barrier and immune dysfunction. Many immune cytokine pathways are amplified in AD, including T helper (Th) 2, Th22, Th17 and Th1. Current treatment guidelines recommend topical medications as initial therapy; however, until recentl...

Systemic medications are often required for severe atopic dermatitis (AD) refractory to topical therapies. Biologic medications are a recent advancement in the field and a comparison to traditional systemic approaches would be beneficial.

Irritant Contact Dermatitis.

Contact dermatitis accounts for 95% of occupational skin disorders. Irritant contact dermatitis (ICD) is often caused by cumulative exposure to weak irritants, accounting for 80% of all cases of contact dermatitis. ICD can co-exist with atopic dermatitis (AD) and allergic contact dermatitis (ACD). Patients with AD and ACD may have a lower inflammatory threshold for developing ICD. Therefore, it ne...

Serum amyloid A levels in the blood of patients with atopic dermatitis and cutaneous T-cell lymphoma.

Serum amyloid A (SAA) is an acute phase protein, which activates immune cells and induces cytokines and chemokine. SAA levels in blood have been reported to be elevated in case of inflammation, infections, neoplasia and tissue injury. In this study, we examined SAA levels in the blood of patients with atopic dermatitis (AD) and cutaneous T-cell lymphoma (CTCL). SAA levels in sera of AD patients, t...

Vesicular hand dermatitis.

Vesicular hand dermatitis is a type of eczema involving the fingers, hands, and sometimes the feet. It is common in primary care, requiring prompt treatment to prevent chronicity. The cause is often unknown, making the condition challenging to treat. Management consists of avoiding irritants and using emollients and topical corticosteroids.

Fas/FasL pathway and cytokines in keratinocytes in atopic dermatitis - Manipulation by the electromagnetic field.

Atopic dermatitis (AD) is one of the most frequent skin diseases. Changes of the keratinocytes functionality play a major role in the development of AD. For example, activation of the Fas (CD95)/FasL (CD178) pathway in AD does not lead to extensive apoptosis in skin. Binding of the Fas receptor to its protein ligand-FasL, which are present on the (AD)-modified keratinocytes, should result in the s...

Exposure to Environmental Tobacco Smoke and Prevalence of Atopic Dermatitis among Adolescents in Kuwait.

This study aimed to (i) assess the prevalence of exposure to environmental tobacco smoke (ETS) at homes, (ii) assess the prevalence of atopic dermatitis and (iii) evaluate the association between ETS exposure and atopic dermatitis status among adolescents.

Mexican consensus on the diagnosis and treatment of atopic dermatitis in adolescents and adults.

The diagnostic approaches and therapeutic strategies of atopic dermatitis (AD) are generally inconsistent among physicians and health institutions.

Analysis of the Association of Polymorphisms rs5743708 in TLR2 and rs4986790 in TLR4 with Atopic Dermatitis Risk.

We carried out a meta-analysis to assess whether Toll-like receptor 2 (TLR2) rs5743708 and Toll-like receptor 4 (TLR4) rs4986790 polymorphisms are associated with the risk of atopic dermatitis.

Stellera chamaejasme and Its Main Compound Luteolin 7-O-Glucoside Alleviates Skin Lesions in Oxazolone- and 2,4-Dinitrochlorobenzene-Stimulated Murine Models of Atopic Dermatitis.

The aim of this study was to determine whether and its major component, luteolin 7--glucoside, have a preventive effect on the development of atopic dermatitis in oxazolone-treated BALB/c mice and 2,4-dinitrochlorobenzene-treated hairless mice. The epicutaneous applicatio...

Patch Testing Pearls.

Dermatitis is one of the most common illnesses encountered by healthcare providers and the causes are numerous. Contact dermatitis is the form of dermatitis resulting from contact with the environment, and it may be either irritant or allergic in nature. Patch testing has been the gold standard for diagnosis of allergic contact dermatitis since its formal description over 100 years ago by Jadasso...

Staphylococcus aureus from atopic dermatitis skin accumulates in the lysosomes of keratinocytes with induction of IL-1α secretion via TLR9.

Staphylococcus aureus (S. aureus) is frequently detected in the skin of patients with atopic dermatitis (AD), and involved in the flare of AD. There are some evidence specific strains of S. aureus affect the severity of AD. However, the mechanism of predominant colonization and the aggravation of dermatitis by certain strains of S. aureus in the patients with AD are still unknown.
