Abstract Diabetic nephropathy is the most common pathological disorder predisposing patients to end-stage renal disease. Considering the increasing prevalence of type 2 diabetes mellitus worldwide, novel therapeutic approaches are urgently needed. ONO-1301 is a novel sustained-release prostacyclin analog that inhibits thromboxane A2 synthase. Here we examined the therapeutic effects of the intermittent administration of slow-release ONO-1301 (SR-ONO) on diabetic nephropathy in obese type 2 diabetes mice, as well as its direct effects on mesangial cells. The subcutaneous injection of SR-ONO (3mg/kg) every 3 wks did not affect the obesity or hyperglycemia in the db/db obese mice used as a model of type 2 diabetes, but it significantly ameliorated their albuminuria, glomerular hypertrophy, glomerular accumulation of type IV collagen, and monocyte/macrophage infiltration, and also the increase of TGF-β1, α-smooth muscle actin (α-SMA) and MCP-1 compared to vehicle treatment. In cultured mouse mesangial cells, ONO-1301 concentration-dependently suppressed the increases in TGF-β, type IV collagen, α-SMA, MCP-1 and fibronectin induced by high ambient glucose, at least partly through prostacyclin (PGI2) receptor-mediated signaling. Taken together, these results suggest the potential therapeutic efficacy of the intermittent administration of SR-ONO against type 2 diabetic nephropathy, possibly through protective effects on mesangial cells.

Abstract Experimental studies have demonstrated the involvement of angiogenesis-related factors in the progression of chronic kidney disease (CKD). There have so far been no reports investigating the distribution and clinical roles of Vasohibin-1 (VASH-1), a negative feedback regulator of angiogenesis, in CKD. We recruited 54 Japanese CKD patients and 6 patients who had normal renal tissues excised due to localized renal cell carcinoma. We evaluated the correlations between the renal expression level of VASH-1 and the clinical/histological parameters. VASH-1 was observed in renal endothelial/mesangial cells, crescentic lesions and interstitial inflammatory cells. Significant positive correlations were observed between 1) crescent formation and the number of VASH-1+ cells in the glomerulus (r=0.48, p=0.001) or cortex (r=0.64, p<0.0001), 2) interstitial cell infiltration and the number of VASH-1+ cells in the cortex (r=0.34, p=0.02), 3) the glomerular VEGFR-2+ area and the number of VASH-1+ cells in the glomerulus (r=0.44, p=0.01) or medulla (r=0.63, p=0.01). These results suggest that the renal levels of VASH-1 may be affected by local inflammation, crescentic lesions and VEGFR-2.

Abstract <p>An unusual case is described in which an abdominal wall and thigh abscess was an initial symptom of ascending colon cancer. A 76-year-old woman was referred to our hospital for investigation of fever and abdominal and thigh swelling. Computed tomography revealed a right abdominal wall, retroperitoneal, psoas and thigh abscess formation suspected to be caused by colon perforation. Due to the patient's poor general condition, local drainage of the abscess was performed on the following day of hospitalization. Histological examination of necrotic tissues removed form the retroperitoneal cavity demonstrated adenocarcinoma of the colon. The patient subsequently underwent right hemicolectomy with lymph nodal dissection after 19 days of the drainage procedure and was transferred to another hospital on the 49th day following the second surgery.</p>
