Abstract Immunosuppressive agents are generally administered to treat kidney diseases. However, it is unclear whether renal stem/progenitor cells are directly affected by the immunosuppressive agents. We used normal rat kidney cells, ureteric bud cells and rat kidney stem/progenitor cells in this study. Mizoribine (MZR), cyclophosphamide (CPA) and cyclosporine (CyA) were added to the culture media of these cells. We evaluated the effects of these immunosuppressive agents on cell proliferation using an electrical cell-substrate impedance sensing system (ECIS) and their effects on the process of renal regeneration using the ischemia-reperfusion (I/R) injury rat model. The ECIS data showed that proliferation of each of the 3 types of cells was significantly suppressed by MZR. MZR treatment enhanced renal tubular injury in ischemia-reperfusion (I/R) injured rats, and significantly decreased levels of M-phase cells and Nestin-positive cells. These results suggested that MZR inhibits the cell cycle of renal stem/progenitor cells;thus, physicians should take note that MZR might affect not only inflammation but also renal regeneration.

Abstract The link between lifestyle modification and changes in both proteinuria and estimated glomerular filtration rates (eGFRs) was evaluated in Japanese subjects with proteinuria who were not taking medications. We used data from 51 men (35.8±10.0 years) and 74 women (38.0±11.0 years) with proteinuria at baseline and a 1-year follow up. eGFR was defined by a new equation developed specifically for Japanese subjects. Subjects were given advice for dietary and lifestyle improvement at the initial appointment. At the 1-year follow up, eGFR was increased in both sexes, but not at significant levels. (men:p=0.7709, women:p=0.2180). Proteinuria was also improved in many subjects. A decrease in proteinuria may be associated with improving eGFR in Japanese.

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 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 In recent years, many researchers have emphasized the importance of metabolic syndrome based on its increasing prevalence and its adverse prognosis due to associated chronic vascular complications. Upstream of a cluster of metabolic and vascular disorders is the accumulation of visceral adipose tissue, which plays a central role in the pathophysiology. In the accumulation of adipose tissues, cell cycle regulation is tightly linked to cellular processes such as proliferation, hypertrophy and apoptosis. In addition, various cell cycle abnormalities have also been observed in other tissues, such as kidneys and the cardiovascular system, and they are critically involved in the progression of disease. Here, we discuss cell cycle abnormalities in metabolic syndrome in various tissues. Furthermore, we describe the role of nuclear receptors in cell growth and survival, and glucose and lipid metabolism in the whole body. Therapeutic strategies for modulating various cell cycles in metabolic disorders by targeting nuclear receptors may overcome obesity and its chronic vascular complications in the future.

Abstract Angiotensin receptor blockers (ARBs) are the first-line antihypertensive agents. In clinical practice, it is often difficult to achieve the recommended blood pressure level by ARBs in their ordinal dosages alone. This study examined the practical efficacy of a combination therapy of ARB with thiazide diuretics for lowering morning home blood pressure (MHBP) in comparison to high-dose ARB therapy in patients with morning hypertension administered an ordinal dosage of ARB. This study was performed in a prospective, randomized, open-labeled and blind-endpoint fashion. Patients were considered to have morning hypertension when their self-measured systolic MHBPs were 135mmHg or higher, irrespective of their diastolic MHBP and office blood pressures (OBPs). Forty-eight outpatients with morning hypertension receiving the ordinal dosage of ARB were given either losartan/hydrochlorothiazide (n=26) or high-dose ARB (n=22) in place of their previously prescribed ARB. No change in any medication was permitted during this period. Decreases of both systolic and diastolic MHBP after 3 months of treatment were significantly greater in the losartan/hydrochlorothiazide group than in the high-dose ARB group (p<0.05, respectively). The ratio of adverse events was somewhat high (23.1% in the losartan/hydrochlorothiazide group, 9.1% in the high-dose ARB group, respectively). However, there were no significant differences in any particular adverse event between groups. This study suggested losartan/hydrochlorothiazide might be superior to high-dose ARB for reducing morning home blood pressure.

Abstract  Public education programs about chronic kidney disease (CKD) have been performed in Okayama, Japan for the past 10 years. The present study investigated the perception of CKD in a general population in Okayama. In October and November 2015, a questionnaire survey was distributed by 12 medical centers in five medical districts in Okayama prefecture. A total of 7,022 respondents who underwent their physical checkup at these centers answered the questionnaire. In response to a questionnaire item asking about the respondent's familiarity with the term "CKD," only 4% of the respondents answered "know it well" and 10% answered "unfamiliar." In contrast, in response to a questionnaire item asking about the respondent's familiarity with "chronic kidney disease," 27% answered "know it well" and 38% answered "unfamiliar." The leading avenue by which the respondents learned about CKD/chronic kidney disease was television, followed by newspapers, magazines, and a family doctor or nurse. The leading component which the respondents considered essential for the diagnosis of CKD/chronic kidney disease was proteinuria. A stratified analysis demonstrated a higher recognition of “CKD" or “chronic kidney disease" in the medical districts in northern Okayama prefecture compared to southern Okayama prefecture. These results indicated that the awareness of CKD in Okayama prefecture is still inadequate. Many people did not appear to realize that the term “CKD" represents "chronic kidney disease". Further continuous public education efforts are required to enlighten people about CKD/chronic kidney disease.

Abstract The aim of this study was to clarify the factors associated with the remission and/or regression of microalbuminuria in Japanese patients with type 2 diabetes mellitus. We retrospectively analyzed the data of 130 patients with type 2 diabetes mellitus with microalbuminuria for 2-6 years (3.39±1.31 years). Remission was defined as improving from microalbuminuria to normoalbuminuria using the albumin/creatinine ratio (ACR), and regression of microalbuminuria was defined as a decrease in ACR of 50% or more from baseline. Progression of microalbuminuria was defined as progressing from microalbuminuria to overt proteinuria during the follow-up period. Among 130 patients with type 2 diabetes mellitus with microalbuminuria, 57 and 13 patients were defined as having remission and regression, respectively, while 26 patients progressed to overt proteinuria. Sex (female), higher HDL cholesterol and lower HbA1c were determinant factors associated with remission/regression of microalbuminuria by logistic regression analysis. Lower systolic blood pressure (SBP) was also correlated with remission/regression, but not at a significant level. These results suggest that proper control of blood glucose, BP and lipid profiles may be associated with remission and/or regression of type 2 diabetes mellitus with microalbuminuria in clinical practice.
