Abstract Background To assess the association between plasma retinol-binding protein 4 (RBP4) levels both in the first trimester and second trimester and risk of gestational diabetes mellitus (GDM). Methods Plasma RBP4 levels and insulin were measured among 135 GDM cases and 135 controls nested within the Peking University Birth Cohort in Tongzhou. Multivariable linear regression analysis was conducted to assess the influence of RBP4 levels on insulin resistance. Conditional logistic regression models were used to compute the odds ratio (OR) and 95% confidence interval (CI) between RBP4 levels and risk of GDM. Results The GDM cases had significantly higher levels of RBP4 in the first trimester than controls (medians: 18.0 μg/L vs 14.4 μg/L; P < 0.05). Plasma RBP4 concentrations in the first and second trimester were associated with fasting insulin, homeostasis model assessment for insulin resistance (HOMA-IR), and the quantitative insulin sensitivity check index (QUICKI) in the second trimester (all P < 0.001). With adjustment for diet, physical activity, and other risk factors for GDM, the risk of GDM increased with every 1-log μg/L increment of RBP4 levels, and the OR (95% CI) was 3.12 (1.08–9.04) for RBP4 in the first trimester and 3.38 (1.03–11.08) for RBP4 in the second trimester. Conclusions Plasma RBP4 levels both in the first trimester and second trimester were dose-dependently associated with increased risk of GDM.

<b><i>Background:</i></b> Arteriovenous fistula (AVF) is the most common vascular access for patients undergoing hemodialysis (HD). Neointimal hyperplasia (NIH) might be a potential mechanism of AVF dysfunction. Retinol-binding protein 4 (RBP4) may play an important role in the pathogenesis of NIH. The aim of this study was to investigate whether AVF dysfunction is associated with serum concentrations of RBP4 in HD subjects. <b><i>Methods:</i></b> A cohort of 65 Chinese patients undergoing maintenance HD was recruited between November 2017 and June 2019. The serum concentrations of RBP4 of each patient were measured with the ELISA method. Multivariate logistic regression was used to analyze data on demographics, biochemical parameters, and serum RBP4 level to predict AVF dysfunction events. The cutoff for serum RBP4 level was derived from the highest score obtained on the Youden index. Survival data were analyzed with the Cox proportional hazards regression analysis and Kaplan-Meier method. <b><i>Results:</i></b> Higher serum RBP4 level was observed in patients with AVF dysfunction compared to those without AVF dysfunction events (174.3 vs. 168.4 mg/L, <i>p</i> = 0.001). The prevalence of AVF dysfunction events was greatly higher among the high RBP4 group (37.5 vs. 4.88%, <i>p</i> = 0.001). In univariate analysis, serum RBP4 level was statistically significantly associated with the risk of AVF dysfunction (OR = 1.015, 95% CI 1.002–1.030, <i>p</i> = 0.030). In multivariate analysis, each 1.0 mg/L increase in RBP4 level was associated with a 1.023-fold-increased risk of AVF dysfunction (95% CI for OR: 1.002–1.045; <i>p</i> = 0.032). The Kaplan-Meier survival analysis indicated that the incidence of AVF dysfunction events in the high RBP4 group was significantly higher than that in the low-RBP4 group (<i>p</i> = 0.0007). Multivariate Cox regressions demonstrated that RBP4 was an independent risk factor for AVF dysfunction events in HD patients (HR = 1.015, 95% CI 1.001–1.028, <i>p</i> = 0.033). <b><i>Conclusions:</i></b> HD patients with higher serum RBP4 concentrations had a relevant higher incidence of arteriovenous dysfunction events. Serum RBP4 level was an independent risk factor for AVF dysfunction events in HD patients.

Aim and purpose: Progressive stroke (PS) lacks effective treatment measures and leads to serious disability or death. Retinol binding protein 4 (RBP4) could be closely associated with acute ischemic stroke(AIS). We aimed to explore plasma RBP4 as a biomarker for detecting the progression in patients with AIS. Methods: Participants of this retrospective study were 234 patients with AIS within the 48 h onset of disease. The primary endpoint was to ascertain if there was PS through the National Institute of Health stroke scale (NIHSS), early prognosis was confirmed through the modified Rankin scale score (mRS) at discharge or 14 days after the onset of stroke, and determine the significance of demographic characteristics and clinical data . Results: In this study, 43 of 234 patients demonstrated PS. . The level of plasma RBP4 in patients with progressive stroke was significantly lower (29 mg/L, 22.60－40.38 mg/L) than that without progression (38.70 mg/L, 27.28－46.40 mg/L, P = 0.003). In patients with lower plasma RBP4, he proportion of patients with progression (c2 = 9.63, P = 0.008) and with mRS scores ≥2 (c2 = 6.73, P = 0.035) were significantly higher Multivariate logistic regression analysis showed that a lower RBP4 level on admission was an independent risk factor for progressive stroke during hospitalization with an OR value of 2.70 (P = 0.03, 95% CI: 1.12－6.52). Conclusion: A low plasma RBP4 level on admission could be an independent risk factor of PS during hospitalization.
