Gastro-colic Fistula-associated Hypersplenism Causes Pancytopenia in a Patient with Crohn's Disease: A Case Report.
A 24-year-old woman was admitted to our hospital due to abdominal pain and a high fever. She was diagnosed with ileocolonic Crohn's disease (CD), complicated with a gastro-colic fistula and splenomegaly. After initial treatment with an infliximab-biosimilar, all blood cell line counts markedly decreased. ⋯ Thus, her pancytopenia was deemed to have likely been caused by hypersplenism. Surgery was performed, and clinical remission was maintained without pancytopenia. This is the first report of a CD patient with pancytopenia caused by hypersplenism that was triggered by gastro-colic fistula-associated splenic vein obstruction.

Eosinophils are important effector cells in airway inflammation, as pleiotropy and heterogeneity can be linked to various pathophysiologies in asthma and chronic obstructive pulmonary disease (COPD). Sputum eosinophils can reflect the heterogeneity of airway inflammation, and owing to their traits, blood eosinophils can be a surrogate and potential biomarker for managing both conditions. ⋯ Thus, there is growing interest in the use of blood eosinophils for the management of these diseases. Compiling recent evidence, we herein review the significance of measuring blood eosinophils in asthma and COPD.

Objective The severity of Clostridioides difficile infection (CDI) is an important prognostic factor. The "MN criteria," proposed in Japan in 2017, attempted to remedy the shortfalls in the reported guidelines proposed globally to determine CDI severity. We therefore assessed the accuracy of the MN criteria and validated the important factors associated with predicting CDI severity. ⋯ Results The screening of the fulminant cases and classification of the non-fulminant cases into mild/moderate and severe/super severe cases resulted in a sensitivity of 1.00 and a specificity of 0.89. Univariate and multivariate analyses revealed a significant association of the serum albumin (Alb) level as well as white blood cell (WBC) count with clinical events. Conclusion The findings provide evidence supporting the accuracy of the MN criteria in predicting CDI severity and show that the Alb and WBC are important variables in predicting CDI severity.

Objective To investigate the pathogenesis of Philadelphia (Ph)-positive acute lymphocytic leukemia (ALL), we established a lymphoblastoid cell line. Methods Bone marrow cells from a patient with Ph-positive ALL were enriched by Ficoll-Hypaque centrifugation and cultured in medium with fetal calf serum. ⋯ Furthermore, the cells were positive for CD13 and CD33 in addition to CD19, CD22 and CD79a antigens. Conclusion This unique cell line is expected to be a valuable tool for understanding the pathogenesis of Ph-positive ALL.

Most cases of liver dysfunction in pregnancy are pregnancy-related, but the onset of systemic autoimmune diseases is also differentiated. A 24-year-old woman presented with liver dysfunction at 28 weeks' gestation with suspected autoimmune hepatitis and started taking ursodeoxycholic acid. ⋯ Since the patient had major symptoms during the puerperium, she was diagnosed with adult-onset Still's disease. When encountering a patient with liver dysfunction during pregnancy, we should also consider the onset of autoimmune diseases.
