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.

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.

Retinol-binding protein 4 (RBP4) is a plasma protein involved in retinol transportation, and recent evidence in rodents suggests that RBP4 is also a metabolic regulator that modifies insulin sensitivity. To assess how RBP4 levels are regulated in ruminants, we determined the RBP4 concentrations in bovine plasma and milk using Western blot analysis. Plasma RBP4 levels in non-pregnant non-lactating (control) cows were around 45 μg/ml, which were sustained during 60-h fasting, but decreased significantly 4 h after lipopolysaccharide (LPS) administration. Basal plasma retinol concentration was around 30 μg/dl, but this decreased to approximately one-third and one-half of these values during fasting and 8 h after LPS challenge, respectively. Plasma RBP4 and retinol levels in cows 3–6 d before parturition were comparable to those of the controls. However, on the day of parturition both were significantly decreased and had returned to basal levels by two weeks after calving. Interestingly, RBP4 was clearly detected in colostrum (16·4±5·6 μg/ml) but was only faintly detected in milk from cows at 7 d and 15 d after calving. Retinol concentrations in colostrum were almost 10-fold higher than those in plasma, while those in milk were comparable to those in plasma. These results suggest that RBP4 and retinol levels are independently regulated under physiological and pathophysiological conditions and that RBP4, like retinol, is transferred from maternal stores to calves through colostrum.
