Article Abstract
Psoriasis is a common, chronic dermatological disorder. Inflammatory cells assemble in epidermis in the early stage of acute psoriasis. Accumulation of neutrophils at the site of inflammation depends on the expression of adhesion molecules. A variety of stimuli--mediators or selectins can active CD11b/CD18 molecules on the neutrophils surface. The aim of our study was expression of CD11b/CD18 molecules without and after stimulation by fMLP (formyl-Met-Leu-Phe) in patients with psoriasis vulgaris treated by PUVA. Expression of beta2-integrins was estimated with MFI (mean fluorescence intensity). Neutrophils in patient with acute psoriasis showed an increase in CD11b/CD18 expression. It means about an activation of neutrophils and particular role of those molecules in granulocyte adhesion to epidermis in psoriasis.
Systemic lupus erythematosus (SLE) is the prototype of an autoimmune disease with various manifestations in the skin and several other organs. Subacute cutaneous lupus erythematosus may present with annular and psoriasiform lesions. There have been case reports of pustular lesions in SLE.

is a plant widely cultivated for food and medicinal purposes. species have been reported as anti-inflammatory, antibacterial, anxiolytic, and antinephritic agents. This study aimed to evaluate the anti-inflammatory potential of the ethanolic extract (EE) from the aerial parts of and its most promising fraction in models of acute and chronic inflammation, including a psoriasis-like mouse model.
Case Presentation: A female patient with a known history of pustular psoriasis presented with sub-acute development of diffuse erythema and scaling of the skin with areas of exfoliation consistent with erythroderma. She was ill appearing and required admission and aggressive treatment with steroid-impregnated wet dressings, topical emollients, analgesics, and systemic immunosuppressants.
Discussion: Erythroderma is a dermatologic emergency characterized by diffuse erythema and scaling spanning greater than 90% of skin surfaces and is associated with a mortality rate as high as 64%.
Generalized pustular psoriasis (GPP) is a severe autoinflammatory keratinization disease (AiKD) characterized by acute flares of widespread sterile pustules and high fever. GPP is potentially life-threatening. Recently clarified genetic predisposing factors for GPP suggest that the excessive activation of innate immune pathways in the skin, including of interleukin (IL)-1 and IL-36 signaling, plays a significant role in the GPP pathogenesis.
Low-dose methotrexate has been proposed as therapy for patients with severely disabling psoriasis and psoriatic arthritis. However, it can be associated with severe toxicity, such as pancytopenia, characterized by anemia (hemoglobin level <13 g/dL in men), thrombocytopenia (platelet count <150 × 109/L), and neutropenia or agranulocytosis (neutrophil count <1.5 × 109/L and 0.
