Background and objectives: This study investigated whether the slope of estimated GFR is different between nonproteinuric subjects with and without diabetes, and what clinical factors are associated with the GFR slope.

Design, setting, participants, & measurements: An observational cohort study was performed in 923 subjects, and the predictive value of baseline variables on the GFR slope was investigated.

Results: On the basis of the median 3-yr follow-up and 7 measurements of GFR, GFR slope (%/yr, median and interquartile range) was significantly larger in subjects with diabetes (–2.39 (–4.86 to 0.15), n = 729) than in those without diabetes (–1.02 (–4.28 to 1.37), n = 194), and this difference remained significant with or without presence of hypertension. After adjustments for confounding factors, predictors of GFR decline were found to be baseline high values of glycosylated hemoglobin A1C (HbA1C), GFR, systolic blood pressure, and low plasma total protein in subjects with diabetes, whereas only the latter two were significant in subjects without diabetes. In subjects with diabetes, the high GFR was accounted for by high HbA1C at baseline, and the predictors of GFR decline differed between those with and without hypertension, or with high and low baseline GFR. Any combination of the predictors showed increased risk for GFR decline.

Conclusions: GFR slope is substantially affected by multiple factors at various stages. The degree of chronic hyperglycemia is likely to play a crucial role in elevating GFR and accelerating the decline in patients with type 2 diabetes even from the normoalbuminuric stage.

Association of sulphatide with influenza A virus (IAV) haemagglutinin (HA) delivered to the cell surface promotes progeny virus production. However, it is not known whether there is direct binding of HA to sulphatide. In this study, we found that recombinant HA, which was produced by a baculovirus protein expression system from the HA gene of A/duck/HK/313/4/78 (H5N3), bound to sulphatide in a dose-dependent manner and that the binding was inhibited by a specific antibody. Our results indicate that the recombinant HA is useful for elucidation of the binding domain of HA with sulphatide and for the development of new anti-IAV agents.

Chromatin-remodeling factor ISWI is a microtubule-associated protein that contributes to chromosome segregation by stabilizing microtubules during anaphase.
