Çebi et al. Cytokine and TFH Activity in MG than those in the treated group, whereas the Tfh1 cells were decreased compared with those in the controls. The relevance of CXCR5 and PD-1 in the pathogenesis of AChR-MG was also suggested by the increased presence of these molecules on mature CD4 single-positive thymocytes from the thymic samples. The study provides further evidence for the importance of IL-21, IL-17A, IL-4, and IL-10 in AChR-MG. Disease-related CD4 + T cells are identified mainly as PD-1 + or ICOS + with or without CXCR5, resembling cTfh cells in the circulation or probably in the thymus. AChR-MG and SN-MG seem to have some similar characteristics. IS treatment has distinctive effects on cytokine expression.
Complete regression of primary OALs without recurrence was observed in about one-third of eyes after systemic rituximab monotherapy. Adjunctive radiotherapy was required in remaining two-thirds of the cases to achieve complete response. Thus, considering the balance between high rate of local control and potential ocular complications of radiotherapy, systemic rituximab can be considered as a first-line therapeutic option in the management of primary OAL.
A case report of simultaneous presentation of chronic neutrophilic leukemia and multiple myeloma (IgG kappa) in a 71-year-old male is described. The patient showed mature neutrophilic leukocytosis, hepatosplenomegaly, high neutrophil alkaline phosphatase score, hyperuricemia, neutrophils with toxic granulation and Döhle bodies, absence of Philadelphia chromosome and of the bcr-abl fusion gene. Moreover, a monoclonal IgG kappa paraproteinemia (36.93 g l(-1)) was detected. Bence-Jones proteinuria was 3.84 g l(-1). The bone marrow was grossly hypercellular with marked myeloid hyperplasia and aggregates of plasma cells. The patient died of severe bronchopneumonia after the transformation of chronic neutrophilic leukemia to acute myelomonocytic leukemia, 1.5 years following diagnosis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
