Background: The complement system is part of the immune system in acute coronary syndrome (ACS). Adiponectin has anti-atherogenic and anti-inflammatory properties. Adiponectin and C1q form a protein complex in blood, and serum C1q binding adiponectin (C1q-APN) can be measured. We investigated the comparative evaluation of serum C1q-APN levels in males with ACS, stable angina pectoris (SAP) versus controls.Methods: The study subjects were 138 Japanese patients who underwent diagnostic coronary angiography. Blood total adiponectin (Total-APN), C1q-APN and C1q were measured by enzyme-linked immunosorbent assays. Patients were divided into three groups according to the clinical condition: ACS (n = 78), SAP (n = 41) or normal coronary (NC, n = 19) groups.Results: Serum C1q levels were significantly higher in the ACS group (54.9±1.2 μg/mL) than in the NC group (48.0±2.5 μg/mL). Although serum Total-APN levels were significantly lower in the SAP and ACS groups, compared with the NC group (7.0±0.5, 7.2±0.3, 10.6±2.0 μg/mL, respectively), serum C1q-APN levels were significantly higher in the ACS group than in the NC and SAP groups (112.1±4.1, 66.3±4.4, 65.7±2.9 units/mL, respectively).Conclusions: Patients with ACS had higher serum C1q-APN levels.Trial Registration: UMIN000002997. © 2014 Kishida et al.; licensee BioMed Central Ltd.

Gastric Cancer | Year: 2016

Background: Pylorus-preserving gastrectomy (PPG) is increasingly being used to treat early gastric cancer in the middle third of the stomach, with the hope of ameliorating postoperative dysfunction and improving quality of life (QOL). We evaluated symptoms of postgastrectomy syndrome (PGS) and QOL by means of a newly developed integrated questionnaire, the Postgastrectomy Syndrome Assessment Scale-45 (PGSAS-45), and compared PPG with Billroth-I distal gastrectomy (DGBI). Methods: The PGSAS-45 consists of 45 items, including items from the SF-8 and GSRS instruments, as well as 22 newly selected items. It was designed to assess the severity of PGS and the living status and QOL of gastrectomized patients. The nationwide PGSAS surveillance study enrolled 2,368 gastric cancer patients who underwent various types of gastrectomy. In this study we analyzed 313 PPG patients and 909 DGBI patients. Results: Body weight loss was −6.9 % in the PPG group and −7.9 % in the DGBI group (P = 0.052). The PPG group scored better on the diarrhea subscale (PPG; 1.8 vs. DGBI; 2.1, P < 0.0001), dumping subscale (1.8 vs. 2.0, P = 0.003), and frequency of additional meals (1.8 vs. 1.9, P = 0.034). Multiple regression analysis revealed that age and the preservation of the celiac branch of the vagus nerve were independent factors predicting diarrhea and dumping. Conclusions: It has been suggested that PPG is superior to DGBI for ameliorating PGS. Preservation of the celiac branch of the vagus nerve is recommended to reduce postoperative disorders regardless of the reconstruction method used. © 2015, The International Gastric Cancer Association and The Japanese Gastric Cancer Association.

Context: Proprotein convertase subtilisin/kexin 9 (PCSK9) is known to be a good target to decrease LDL cholesterol (LDL-C) and two forms of PCSK9, mature and furin-cleaved PCSK9, circulate in blood. However, it has not been clarified whether and how the levels of each PCSK9 are affected by LDL-apheresis (LDL-A) treatment, a standard therapy in patients with severe forms of familial hypercholesterolemia (FH). Objective: Our objective was to investigate the differences in LDL-A-induced reduction of mature and furin-cleaved PCSK9 between homozygous and heterozygous FH, and between dextran sulfate (DS) cellulose adsorption and double membrane (DM) columns and to clarify the mechanism of their removal. Design: A sandwich ELISA to measure two forms of PCSK9s using monoclonal antibodies was developed. Using the ELISA, PCSK9 levels were quantified before and after LDL-A with DS columns in 7 homozygous and 11 heterozygous FH patients. A crossover study between the two column types was performed. The profiles of PCSK9s were analyzed after fractionation by gel filtration chromatography. Immunoprecipitation of apolipoprotein B (apoB) in FH plasma was performed. Results: Both mature and furin-cleaved PCSK9s were significantly decreased by 55-56% in FH homozygotes after a single LDL-A treatment with DS columns, and by 46-48% or 48-56% in FH heterozygotes after treatment with DS orDMcolumns. The reduction ratios of LDL-C were strongly correlated with that of PCSK9 in both FH homozygotes and heterozygotes. In addition, more than 80% of plasma PCSK9s were in the apoB-deficient fraction and a significant portion of mature PCSK9 was bound to apoB, as shown by immunoprecipitation. Conclusions: Both mature and furin-cleaved PCSK9s were removed by LDL-A in homozygous and heterozygousFHeitherbybindingtoapoBorbyothermechanisms.TheELISAmethodtomeasureboth forms of plasma PCSK9 would be useful for investigating physiological or pathological roles of PCSK9. © 2015 by the Endocrine Society.

Two cases of unilateral synchronous occurrence of renal pelvic urothelial carcinoma and renal cell carcinoma are presented. Case 1: A 70-year-old woman presented with macroscopic hematuria. Retroperitoneoscopic nephroureterectomy was performed under the diagnosis of renal pelvic carcinoma. Pathological diagnosis was not only renal pelvic urothelial carcinoma but also renal cell carcinoma 1.5 × 0.5 mm in diameter. Case 2: A 79-year-old man with hormonal therapy for prostate cancer complained of macroscopic hematuria. Right nephroureterectomy was performed under the diagnosis of right renal pelvic carcinoma and right renal cell carcinoma. Pathological findings were the same as preoperative diagnosis. To our knowledge, 21 cases of unilateral synchronous occurrence of renal pelvic urothelial carcinoma and renal cell carcinoma have been reported in the Japanese literature including our cases and the clinical features are reviewed.

Diabetology and Metabolic Syndrome | Year: 2014

Background: Adiponectin plays a role as a positive contributor to the stabilization of atherosclerotic plaques. Circulating total adiponectin (Total-APN) levels associates with the number of coronary vessels in men with coronary artery disease (CAD). We recently reported that adiponectin binds to C1q in human blood, and serum C1q-binding adiponectin (C1q-APN) /Total-APN levels are associated with CAD in type 2 diabetic subjects. The present study investigated the relationship between circulating C1q-APN levels and the number of angiographic coronary artery vessel in male subjects. Methods. The study subjects were 53 male Japanese patients who underwent diagnostic coronary angiography. Blood total adiponectin (Total-APN), high-molecular weight adiponectin (HMW-APN), C1q-APN and C1q were measured by enzyme-linked immunosorbent assays. Results: Serum C1q-APN/Total-APN ratio significantly increased in subjects with single and multi-vessel coronary diseases (p = 0.029 for trend, the Kruskal-Wallis test). However, serum Total-APN, HMW-APN, C1q-APN and C1q levels did not correlate with number of diseased coronary vessels. Conclusion: Serum C1q-APN/Total-APN ratio progressively increases in men with single and multi-vessel coronary disease. © 2014 Kishida et al.; licensee BioMed Central Ltd.
