TAFRO syndrome is rare, and its pathophysiology remains unclear. We herein report the case of a 66-year-old man who presented at our emergency department with epigastric pain. Contrast-enhanced computed tomography (CT) showed high-density retroperitoneal panniculus with contrast enhancement. He was treated initially with a protease inhibitor and hydration, to little effect. Anasarca, thrombocytopenia, and renal dysfunction developed gradually, and TAFRO syndrome was diagnosed. He was treated successfully with prednisolone and cyclophosphamide, and subsequent CT findings showed improvement. Abnormal CT findings of the retroperitoneum may indicate the early stages of TAFRO syndrome before the presentation of typical ascites.

The C57BL/6J-Daruma mouse is an animal model of obesity derived from the original genetically obese ICR-Daruma mouse by transfer of the phenotype into the C57BL/6J background by backcrossing into the C57BL/6J strain. Although, like the original ICR-Daruma mouse model, both male and female C57BL/6J-Daruma mice develop obesity, the latter strain shows sex differences in several phenotypes. A sex difference in plasma insulin levels was especially notable in C57BL/6J-Daruma mice; only males showed hyperinsulinemia. Orchiectomy suppressed this hyperinsulinemia completely, whereas testosterone supplementation restored it. Glucose administration increased the plasma glucose level in both male and female Daruma mice to a greater extent than in wild-type control mice. Orchiectomy, but not ovariectomy, decreased the plasma glucose level to that seen in wild-type controls. On the other hand, this effect of orchiectomy was abrogated by testosterone supplementation. The expression of mRNAs for several genes related to insulin resistance was significantly changed in white adipose tissue and liver of C57BL/6J-Daruma mice, especially males, as early as 4 weeks of age. The present results suggest that testosterone may be involved in the hyperinsulinemia shown by male C57BL/6J-Daruma mice and that this strain may be an appropriate animal model for examining the relationship between obesity and sex hormones.

Although cigarette smoking is a recognized cause of acute eosinophilic pneumonia (AEP), and an increase in eosinophils in the lung is a common occurrence in AEP, early-phase neutrophilia in AEP is not well understood. We describe three cases of cigarette smoke (menthol type)-induced AEP with neutrophilia in the lungs or blood. Increased in-vitro production of the neutrophil chemoattractant interleukin (IL)-8 by human bronchial epithelial cells (HBECs) was correlated with neutrophilia. We suggest that IL-8 released from HBECs is involved in neutrophilia in the lung in AEP, and is newly recognized as an important factor in the early phase of AEP development.(Internal Medicine 42: 839-845, 2003)
