Type 2 diabetes is a progressive disease characterized by insulin resistance and insulin secretory dysfunction. In this study, we assessed the factors contributing to an insulin secretory defect in type 2 diabetes patients. ⋯ The duration of diabetes, a low BMI, genetic factors, and the presence of microangiopathy may be associated with β-cell dysfunction in diabetic patients. The observations in this study suggest that obese subjects showed a rapid decline in the β-cell function despite an initial high CPR response. Environmental factors causing insulin resistance and glucotoxicity may therefore be involved in progressive β-cell failure.

The goals of this study were to assess the efficacy and tolerability of pirfenidone in patients with idiopathic pulmonary fibrosis (IPF) and to identify predictors of tolerability to pirfenidone. ⋯ We found that pirfenidone was better tolerated in patients with milder disease symptoms, as indicated by their baseline CPI, %FVC and %DLCO, and that patients in the tolerant group could benefit from the use of pirfenidone.

Prevalence and Associated Factors of Uraemic Pruritus in Continuous Ambulatory Peritoneal Dialysis Patients.
Uraemic pruritus is a distressing symptom that has a negative impact on the quality of life for dialysis patients. The pathophysiology of pruritus in peritoneal dialysis (PD) patients is still poorly understood. The present study aims to investigate the prevalence and related risk factors of pruritus in continuous ambulatory peritoneal dialysis (CAPD) patients. ⋯ The prevalence of uraemic pruritus was 65.2% in CAPD patients. Sleep disorder, depression, longer vintage, and a higher iPTH level were independent associated factors for pruritus in CAPD patients.

This study was designed to determine the SYNTAX score under different fasting plasma glucose (FPG) states in Chinese patients undergoing coronary angiography, particularly subjects with impaired FPG. ⋯ Chinese subjects with impaired FPG have a significantly elevated risk of having an intermediate or high SYNTAX score, indicating a risk of severe coronary artery lesions. Subjects with known or previously unknown T2DM may have severe coronary artery lesions. These findings suggest the importance of achieving better glycemic control in order to prevent coronary atherosclerosis and improve the cardiovascular prognosis.

Uromodulin-associated kidney disease (UAKD) is an autosomal dominant disease caused by a mutation in the uromodulin (UMOD) gene, leading to end-stage renal disease. We herein report the case of a family with UAKD caused by a novel mutation (C135G) in the UMOD gene. ⋯ Her father, grandfather and paternal aunt had received maintenance hemodialysis therapy since their 40's. This case underscores the importance of performing genetic testing in young patients even in cases involving only moderate abnormalities in the kidney function.
