Immunolocalization of MUC1 in chronic plaque psoriasis.

Immunolocalization of MUC1 in chronic plaque psoriasis. J Immunoassay Immunochem. 2019 Jul 26;:1-13 Authors: Abdou AG, Farag AGA, Abdelaziz RA, Samaka RM, Nabil E, Ali M Abstract Psoriasis is a chronic skin inflammatory disease with immunological, hyperproliferative and angiogenic dysfunction. MUC1 is a molecular sensor and signal transductor that responds to external stimuli generating cellular responses, which include cell proliferation, growth, differentiation, migration, invasion, survival and secretion of growth factors, and cytokines. The current study aimed at evaluation of the possible role of MUC1 in the pathogenesis of psoriasis through its immunohistochemical localization in involved and uninvolved psoriatic skin compared to normal skin in addition of correlating MUC1 expression with the clinical and pathological parameters of psoriasis. The current study investigated 30 patients with psoriasis and 10 controls. MUC1 was expressed in epidermis in 30% of normal skin compared to 20% of uninvolved epidermis and 63.3% of involved epidermis of psoriatic skin. MUC1 was seen staining endothelial cells of capillaries and inflammatory cells in dermis in 10% of normal skin, 0% of uninvolved psoriasis, and 83.3% of involved psoriasis. Dermal expression of MUC1 in psoriasis was associated with mild to moderate degrees of epidermal acanthosis (p = .027). Intense MUC1 expression by psoriatic epidermis was associated with short disease duration (p = ...

Conclusions: The mapping algorithms reported in this paper can be used to predict the EQ-5D-5L utilities from the PDI; however, similar to other mapping studies in the literature it can only serve as the second-best approach to elicit utilities from disease-specific instruments.

We describe and analyze the molecular surface character of known binding epitopes for medications in these classes, showing that significant differences exist in epitope location, hydrophobicity, and charge. Some of these differences can be correlated with clinical data, but our analysis ultimately points to the need for more structural information to allow for a better understanding of the structure-function relationship of biologic therapies.

‚ÄčThe wrist is not commonly aspirated in the emergency department, but emergent arthrocentesis may be indicated for extreme or concerning cases, and tapping the wrist to determine the underlying pathology or relieve pain may be of great value. The synovial fluid from the joint space can be analyzed for crystals, infection, and blood. This information may help determine the overall plan and aid in decision-making and consultation. The ultimate treatment plan may include admission, intravenous antibiotics, multiple aspirations, and even surgical washout.A swollen, painful wrist that is hot to the touch is concerning for sep...

Conclusions The top positive and relevant allergens seen were in concordance with other reports from Australia and the rest of the world. Fragrances and medicaments are common allergens, and it is recommended that products used on anogenital skin be fragrance free. Testing patients own products is imperative.

AbstractOne of many hypotheses of psoriasis pathogenesis supposes an overexpression of heat shock proteins (Hsps) in different skin layers and systemic immunologic response to them. Hsp90 is one of the most abundant chaperone in eukaryotic cells. The number of studies concerning the role of Hsp90 and anti-Hsp90 antibodies in etiopathogenesis of various diseases is also constantly expanding. Still, there are not many reports concerning potential involvement of this Hsp family or anti-Hsp90 immunization in pathomechanism of psoriasis. The aim of the study was the estimation of anti-Hsp90 α and anti-Hsp90β IgG anti...
