Three cases of pigmented cosmetic dermatitis‐like eruptions associated with primary Sjögren's syndrome or anti‐SSA antibody 下载免费PDF全文

Pigmented cosmetic dermatitis‐like (Riehl's melanosis‐like) pigmentation was reported in three of 27 patients with primary Sjögren's syndrome. But case reports of such eruptions are rare. We describe three cases of such eruptions associated with primary Sjögren's syndrome or anti‐SSA antibody and possible associations with specific types of human leukocyte antigen (HLA) and infiltrating lymphocytes. These middle‐aged Japanese women had reticular facial pigmentation and histopathological examination revealed interface dermatitis, melanophages, and dense lymphocytic infiltration around hair follicles and sweat ducts. HLA typing revealed common antigenic equivalents or genetic typing of HLA‐A2, DR52, DPA1(02:02) and DPB1(05:01). Immunohistochemical staining revealed major subsets of T cells to be CD8 and CD45RO. Some Foxp3‐ and few IL17‐positive cells were found in strong contrast to the major CD4 subset of infiltrated T cells in annular erythema associated with Sjögren's syndrome. Apparently, our patients' pigmentation represented a specific etiology associated with primary Sjögren's syndrome or anti‐SSA antibody. 相似文献

5-Hydroxytryptamine (5-HT) released from colonic mucosal enterochromaffin (EC) cells is a major signaling molecule, which participates in the pathophysiological regulation of colonic functions in gut disorder including irritable bowel syndrome (IBS), but the endogenous modulator system for the 5-HT release is not yet well elucidated. Our in vitro studies in guinea-pig colon have indicated that the cascade pathway of neuronal tachykinergic NK3 receptors and NK2 receptors on peptide YY (PYY)-containing endocrine L cells represents an endogenous modulator system for 5-HT release from EC cells and that melatonin, endogenous tachykinins and PYY play important roles in modulation of the release of 5-HT from EC cells via the endogenous NK2/NK3 receptor cascade system. This review aims at examining the potential role of the endogenous tachykinergic NK2/NK3 receptor cascade system controlling the release of 5-HT from EC cells, with special attention being paid to the pathophysiology of gut disorders including IBS. 相似文献
