Allergic contact dermatitis is very common and may be complicated by secondary infections. Chronic lymphoedema is a potentially debilitating condition, which may occur due to secondary infections or the dermatitis itself. The problem of chronic lymphoedema following allergic contact dermatitis has been infrequently reported. We report a case of a 47-year-old woman with severe allergic contact d...
Introduction: Allergic contact dermatitis is a skin disease representing a type IV immunological reaction, also known as a delayed reaction, according to Gell and Coombs’ classification. It results from hypersensitivity to contact allergens and manifests itself as allergic contact dermatitis skin lesions. This clinical problem mainly affects adults and can be of occupational or non-occupational...
Contact sensitization is common and affects up to 20% of the general population. The clinical manifestation of contact sensitization is allergic contact dermatitis. This is a clinical expression that is sometimes difficult to distinguish from other types of dermatitis, for example irritant and atopic dermatitis. Several studies have examined the pathogenesis and severity of allergic contact der...
Recent US studies have presented case series of patient with allergic contact dermatitis (ACD) allegedly caused by formaldehyde in clothes treated with durable-press chemical finishes (DPCF), which are known formaldehyde releasers. However, the amounts of formaldehyde released by modern DPCF are thought to be well below the levels previously estimated to be able to elicit ACD. The objectives of...
Allergic contact dermatitis (ACD) remains a leading skin disease in many countries. In this study, we investigated the preventive effect of Piper nigrum fruit extract (PFE) on trimellitic anhydride (TMA)-induced dermatitis and its potential mechanism of action. Oral administration of PFE and prednisolone (PS) significantly suppressed TMA-induced increases in ear, epidermal thickness, and infilt...
Systemic contact dermatitis (SCD), better termed systemically reactivated allergic contact dermatitis, is a type of contact hypersensitivity reaction in which ingestion or other systemic exposure to a contact allergen occurs in an already sensitized person. Although the initial sensitizing exposure is usually by topical application, re-exposure by the oral, intravenous or inhalation routes can ...
Allergic contact dermatitis (ACD) is a skin disease with complex pathophysiology. It well established that epidermal-resident memory CD8+ T (CD8+ TRM) cells are responsible for the rapid flare-up reaction and production of IFNγ IL-17A seen after challenge allergens. Nevertheless, pathways kick off their effector functions unclear. Junctional adhesion molecule-like protein (JAML) was recently de...
Contact dermatitis is a common inflammatory skin condition characterized by erythematous and pruritic skin lesions that occur after contact with a foreign substance. There are two forms of contact dermatitis: irritant and allergic. Irritant contact dermatitis is caused by the non-immune-modulated irritation of the skin by a substance, leading to skin changes. Allergic contact dermatitis is a de...
The anti-allergic mechanism of heat-killed Lactobacillus acidophilus strain L-92 has not been fully investigated. Recent studies have reported that CD4(+)CD25(+)Foxp3(+) (forkhead box P3) T regulatory (Treg) cells play important roles in controlling allergic diseases. Hence, we examined the effect of orally administered L-92 on CD4(+)CD25(+)Foxp3(+) cell populations. BALB/c mice were supplement...
Extending the classical concept considering an imbalance exclusively of T helper(h) 1 and Th2 cells on the bottom of many inflammatory diseases, Th17 cells were recently described. Today, there is sufficient experimental evidence to classify psoriasis and allergic contact dermatitis (ACD) amongst other inflammatory skin disorders as IL-17 associated diseases. In several human studies, T-cell-cl...
