Flow cytometric analysis of skin blister fluid induced by mosquito bites in a patient with chronic active Epstein-Barr virus infection

金沢大学医薬保健研究域医学系In chronic active Epstein-Barr virus (EBV) infection (CAEBV), ectopic EBV infection has been described in T or natural killer (NK) cells. NK cell-type infection (NK-CAEBV) is characterized by large granular lymphocytosis, high IgE levels and unusual reactions to mosquito bites, including severe local skin reactions, fever and liver dysfunction. However, the mechanisms underlying these reactions remain undetermined. Herein, we describe a patient with NK-CAEBV whose blister fluid after mosquito bites was analyzed. The patient exhibited significant increases in the percentage of CD56+ NK cells in the fluid compared with a simple mosquito allergy, in which the majority of infiltrated cells were CD203c+ cells, indicating basophils and/or mast cells. His fluid also contained CD203c+ cells, and his circulating basophils were activated by mosquito extracts in vitro. These results suggest that CD203c+ cells as well as NK cells may play pathogenic roles in the severe skin reactions to mosquito bites in NK-CAEBV. © 2009 The Japanese Society of Hematology.出版者に照会中.2010年12月より全文公開予定

Reactive peripheral blood plasmacytosis in a patient with acute hepatitis A

金沢大学附属病院小児科Reactive plasmacytosis is a transient expansion of plasma cell progenitors and precursors. This rare condition has been reported to occur mainly in infections and tumors. We describe a case of acute hepatitis A presenting with marked peripheral blood plasmacytosis. Plasma cells made up 27.5% of the mononuclear cells and had the immunophenotype CD10-CD19 +CD20-CD21-CD23-CD34 -CD38++HLA-DR+. Although the level of interleukin 6 was not increased, the presence of activated T-cells with an inverted CD4/CD8 ratio and high levels of soluble interleukin 2 receptor and neopterin indicated a marked immune response to acute hepatitis A. The patient\u27s plasma cells had almost disappeared from the blood by hospital day 16. This report may represent the first described case of reactive peripheral blood plasmacytosis in acute hepatitis A. © 2007 The Japanese Society of Hematology

Prevention of hypoglycemia by intermittent-scanning continuous glucose monitoring device combined with structured education in patients with type 1 diabetes mellitus : A randomized, crossover trial

Aims: We conducted a randomized, crossover trial to compare intermittent-scanning continuous glucose monitoring (isCGM) device with structured education (Intervention) to self-monitoring of blood glucose (SMBG) (Control) in the reduction of time below range. Methods: This crossover trial involved 104 adults with type 1 diabetes mellitus (T1DM) using multiple daily injections. Participants were randomly allocated to either sequence Intervention/Control or sequence Control/Intervention. During the Intervention period which lasted 84 days, participants used the first-generation FreeStyle Libre (Abbott Diabetes Care, Alameda, CA, USA) and received structured education on how to prevent hypoglycemia based on the trend arrow and by frequent sensor scanning (≥10 times a day). Confirmatory SMBG was conducted before dosing insulin. The Control period lasted 84 days. The primary endpoint was the decrease in the time below range (TBR; <70 mg/dL). Results: The time below range was significantly reduced in the Intervention arm compared to the Control arm (2.42 ± 1.68 h/day [10.1 %±7.0 %] vs 3.10 ± 2.28 h/day [12.9 %±9.5 %], P = 0.012). The ratio of high-risk participants with low blood glucose index >5 was significantly reduced (8.6 % vs 23.7 %, P < 0.001). Conclusions: The use of isCGM combined with structured education significantly reduced the time below range in patients with T1DM
