GIP_HUMAN[22-51] is a new proatherogenic peptide identified by native plasma peptidomics.

We recently established a new plasma peptidomic technique and comprehensively identified a large number of low-molecular weight and low-abundance native peptides using a single drop of human plasma. To discover a novel polypeptide that potently modulates the cardiovascular system, we performed a bioinformatics analysis of the large-scale identification results, sequentially synthesized the selected peptide sequences, tested their biological activities, and identified a 30-amino-acid proatherogenic peptide, GIP_HUMAN[22-51], as a potent proatherosclerotic peptide hormone. GIP_HUMAN[22-51] has a common precursor with the glucose-dependent insulinotropic polypeptide (GIP) and is located immediately N-terminal to GIP.

Hemodialysis-Related Glycemic Disarray Proven by Continuous Glucose Monitoring; Glycemic Markers and Hypoglycemia.

Objective: There is a high risk of asymptomatic hypoglycemia associated with hemodialysis (HD) using glucose-free dialysate; therefore, the inclusion of glucose in the dialysate is believed to prevent intradialytic hypoglycemia. However, the exact glycemic fluctuation profiles and frequency of asymptomatic hypoglycemia using dialysates containing >100 mg/dL glucose have not been determined.

Research Design And Methods: We evaluated the glycemic profiles of 98 patients, 68 of whom were men, with type 2 diabetes undergoing HD (HbA 6.

Tolvaptan alleviates excessive fluid retention of nephrotic diabetic renal failure unresponsive to furosemide.

Patients with diabetic nephropathy develop nephrotic syndrome and may show limited response to conventional therapy. They often require earlier initiation of renal replacement therapy because they become refractory to diuretics, and experience excessive fluid retention. We aimed to investigate the efficacy of tolvaptan, an oral arginine vasopressin type 2 receptor antagonist, in a case series of 14 severe diabetic renal failure patients who were severely refractory to maximal doses of furosemide and had excessive fluid retention despite preserved cardiac function and residual renal function.

Distinct biomarker roles for HbA and glycated albumin in patients with type 2 diabetes on hemodialysis.

Aims: HbA and glycated albumin (GA) are used to monitor glycemia, but their accuracy to represent glycemic profiles in hemodialysis remains controversial.

Methods: Continuous glucose monitoring in 97 patients with type 2 diabetes (41 on hemodialysis [HD] and 56 without nephropathy) was analyzed to evaluate whether HbA and/or GA serve as appropriate glycemic profile markers.

Results: The average glucose significantly correlated with HbA in both HD group and group without nephropathy (r=0.

A very rare case of primary meningococcal arthritis in an adult male.

We report here a very rare case of primary meningococcal arthritis of the knee joint without clinical features associated with meningococcemia, meningitis, or meningococcal complications. The patient suffered from diabetes mellitus and had experienced two episodes of joint trauma. Intravenous infusion of ampicillin/sulbactam for 18 consecutive days was successful.

Physiological fluctuations of human plasma total salusin-β, an endogenous parasympathomimetic/proatherosclerotic peptide.

Salusin-β is an endogenous bioactive peptide that systemically exerts acute parasympathomimetic hemodynamic actions and locally induces atherogenesis. Due to its unique physicochemical characteristics to immediately adhere to all types of plastic and glassware, its plasma concentrations have only been successfully determined very recently. Using a total of 50 healthy adults (median age 28 years, range 24-57 years), we evaluated whether circulating salusin-β levels are affected by the autonomic nervous functions.
