Gastric Cancer and Paraneoplastic Pemphigus

Paraneoplastic pemphigus is a relatively rare but significant acquired autoimmune mucocutaneous disorder that is characterised by diffuse erythema, painful blistering and sores of the skin and mucus membranes. The underlying pathogenesis is believed to be triggered by altered immune system in response to underlying neoplasm. The manifestations can predate, occur at the same time or after the diagnosis of cancer. Associations with gastric cancer have only been reported twice. A 78-year-old lady presented with a month’s history of extensive skin lesions that started off as bullous lesions and biopsy revealed bullous pemphigus. Endoscopy for anemia revealed gastric cancer. This case reinforced the need to consider underlying malignancy in elderly patient with new onset dermatological presentation.     

Localized Kaposi''s sarcoma in a patient with pemphigus vulgaris

We report the case of a patient with a 13-year history of pemphigus vulgaris (PV) treated with immunosuppressive agents, prednisone and mycophenolate mofetil who had developed lesions of Kaposi's sarcoma (KS) on a sole plaque of PV that had been previously treated with intralesional injections of steroids. The lesions were surgically removed and polymerase chain reaction (PCR) demonstrated human herpesvirus-8 (HHV-8) DNA. There were neither recurrences nor later dissemination of KS following gradual decrease of the immunosuppressive therapy. We suggest that the treatment with intralesional steroids may have influenced the local reactivation of a latent infection of the virus, determining the appearance of this localized KS.     

Effects of chimeric molecule of recombinant Dsg3EC1-2 with toxin PE40 on T and B lymphocytes in Pemphigus Vulgaris

Objective:To observe the effects of the recombinant chimeric toxin Dsg3EC1-2PE40 on T and B lymphocytes isolated from Pemphigus Vulgaris (PV) patients to further study its biological therapeutic function for PV. Methods :Recombinant chimeric toxin Dsg3EC1-2PE40 was first identified, expressed and purified, and then its effects on T and B lymphocytes of PV patients in vitro were detected and quantified by ELISPOT assay and MTT assay. Results :The purity of the expressed protein Dsg3EC1-2PE40 was up to 80%. In ELISPOT assay, with Dsg3EC1-2PE40, the overall number of B cells that produce anti-Dsg3 antibodies among PV patients was only about 60% of the comparable number with Dsg3EC1-2. The proliferation of T cells of PV patients was inhibited markedly by Dsg3EC1-2PE40. There was significant difference between the different groups with Dsg3EC1-2PE40 and Dsg3EC1-2. Conclusion:The recombinant chimeric toxin Dsg3EC1-2PE40 decrease the number of B cells that produce anti-Dsg3 antibodies in PV patients and can inhibit or kill T cells of PV patients in vitro.

大鼠下丘脑室旁核及其邻近区域至室管膜的传出联系

用20只Wistar大鼠以PHA—L免疫组织化学顺行追踪技术研究了下丘脑室旁核及其邻近区域对脑室系统室管膜的传出联系。在脑室系统某些部位的室管膜层或其下方见有丰富的标记纤维并见许多膨结和终末膨突。这些纤维似乎参与形成室管膜上、下丛,构成脑—脑脊液神经体液回路的重要环节。

Ungewöhnliche Strahlenreaktion nach Röntgenweichstrahltherapie bei einer Patientin mit Pemphigus vulgaris

Zusammenfassung Bei einer 71j?hrigen Frau trat nach R?ntgenweichstrahltherapie an der Nase (Gesamtdosis 28 Gy, Gewebehalbwerttiefe 10,5–11,5 mm) eine ausgepr?gte Strahlenerosion auf. Diese zeigte 5 Wochen nach Ende der Bestrahlung noch keine Tendenz zur Abheilung. Ursache dieses ungew?hnlichen Verlaufes war ein gleichzeitig bestehender Pemphigus vulgaris. Dieser hatte sich nach der Strahlentherapie, vermutlich als Folge einer Freisetzung epidermaler Antigene, verschlimmert. Da? der Pemphigus in diesem Fall durch die Bestrahlung ausgel?st wurde – wie mehrfach in der Literatur berichtet – ist unwahrscheinlich, aber nicht sicher auszuschlie?en. Eingegangen am 11. April 1994 Angenommen am 10. Juni 1994     

A case of pemphigus vulgaris possibly triggered by quinolones

Pemphigus vulgaris is an autoimmune blistering disorder in which both genetic and environmental factors, mainly drugs, are thought to play a part in its aetiopathogenesis. Although some drugs that contain thiol groups, such as D-penicillamine and captopril, and non-thiol drugs, such as cephalosporin, have been reported to trigger or induce pemphigus, there are no previous reports regarding the influence of quinolones in triggering this disease. Here we present a case of pemphigus possibly triggered by quinolones.     

Pemphigus Vulgaris Associated with Autoimmune Hemolytic Anemia and Elevated TNFα

A 76-year-old female was admitted with many bullae and erythema on her trunk and extremities. A biopsy specimen showed significant intercellular edema in the lower epidermis and eosinophilic infiltration into the dermis and the epidermis. Immunofluorescent staining revealed the deposition of IgG in the intercellular area of her prickle cells. From these histologic findings and the typical clinical features, we diagnosed her as having pemphigus vulgaris. Examination of her blood revealed that she also suffered from autoimmune hemolytic anemia. Despite intensive treatment with prednisolone, she finally died. This case is of interest because of its rarity and the TNFα detected significantly in the blister fluid of this patient.
