Low Serum Levels of Prealbumin, Retinol Binding Protein, and Retinol Are Frequent in Adult Type 1 Diabetic Patients.

ABSTRACT: Aim. To determine the serum prealbumin (PA), retinol binding protein (RBP), and retinol levels in adult patients with type 1 diabetes (T1D) and to analyze some factors related to those levels. Methods. A total of 93 patients (47 women) were studied. Age, gender, BMI, duration of diabetes, chronic complications, HbA1c, lipid profile, creatinine, albumin, PA, RBP, and retinol were recorded. High and low parameter groups were compared by Mann-Whitney U and ?² tests. Correlation between parameters was analyzed by Spearman's test. Odds of low levels were analyzed by univariate logistic regression and included in the multivariate analysis when significant. Results. 49.5%, 48.4%, and 30.1% of patients displayed serum PA, RBP, and retinol levels below normal values, respectively. A high correlation (Rho > 0.8) between PA, RBP, and retinol serum levels was found. Patients presenting low levels of any of them were predominantly women, normal-weighted, and with lower levels of triglycerides and serum creatinine. No differences in age, macrovascular complications, duration of diabetes, or HbA1c values were observed when comparing low and normal parameter groups. Conclusion. Low serum levels of PA, RBP, and retinol are frequent in T1D adult patients. This alteration is influenced by female sex and serum creatinine and triglyceride levels.

Project description:BackgroundThe interplay between the novel adipokine retinol-binding protein-4 (RBP4) and coronary artery disease (CAD) is still obscure. We investigated the relationship between RBP4 levels and the presence and severity of angiographically proven CAD and determined its possible role in acute myocardial infarction (AMI).Methods305 individuals with angiographically proven CAD (CAD-patients), were classified into 2 subgroups: 1) acute myocardial infarction (AMI, n = 141), and 2) stable angina (SA, n = 164). Ninety-one age- and sex-matched individuals without CAD, but with at least 2 classical cardiovascular risk factors, served as controls (non-CAD group). RBP4 serum levels were measured at hospital admission and were analyzed in relation to the coronary severity stenosis, assessed by the Gensini-score and the number of coronary narrowed vessels. Other clinical parameters, including insulin levels, HOMA-IR, hsCRP, glycaemic and lipid profile, and left-ventricular ejection fraction were also assessed.ResultsSerum RBP4 levels were significantly elevated in patients with CAD compared to non-CAD patients (39.29 ± 11.72 mg/L vs. 24.83 ± 11.27 mg/L, p < 0.001). We did not observe a significant difference in RBP4 levels between AMI and SA subgroups (p = 0.734). Logistic regression analysis revealed an independent association of CAD presence with serum RBP4 (β = 0.163, p = 0.006), and hsCRP (β = 0.122, p = 0.022) levels, in the whole study group. Among variables, hsCRP (β = 0.220), HDL (β = -0.150), and RBP4 (β = 0.297), correlated in both univariate and multivariate analysis with CAD severity (R2 = 0.422, p < 0.001). Similarly, RBP4 concentrations increased with the number of coronary narrowed vessels (p < 0.05).ConclusionPatients with CAD, both SA and AMI, showed elevated RBP4 serum levels. Notably, increased RBP4 concentration seemed to independently correlate with CAD severity, but no with AMI.Trial registrationThe ClinicalTrials.gov Identifier is: NCT00636766.

Project description:Background/aim:Malnutrition is an important and commonly seen prognostic factor in patients with cirrhosis. The diagnosis of malnutrition in cirrhosis patients may be challenging, and an easily measured and widely usable marker is lacking. Prealbumin, however, is an easily measured marker. In the current study we measured prealbumin levels in cirrhotic patients with no clinically apparent malnutrition and used it as a malnutrition marker. Another aim of this study was to evaluate the effect of nutritional support on patient with low prealbumin levels. Materials and methods:Fifty-two patients with Child A and Child B cirrhosis were selected for the study. Prealbumin levels were studied, and Child and MELD scores were calculated. Patients with prealbumin levels ?180 mg/L were considered to have malnutrition, and two different types of nutritional products were given to these patients. The patients given nutritional support were investigated a month later, and parameters were compared. Results:According to the prealbumin threshold of 180 mg/L, malnutrition frequencies were 59.3% for Child A and 95% for Child B cirrhosis. After the provision of nutritional support statistically significant improvements in albumin and INR levels were detected. In addition, the MELD score decreased; however, it was not statistically significant (P: 0.088). A statistically significant decrease in the MELD score was only obtained in patients with Child B cirrhosis (P: 0.033). When the oral replacement therapies were investigated separately, a statistically significant decrease in MELD scores was detected with product 1 (P: 0.043). Conclusion:Prealbumin can be used as an easily measured parameter for earlier detection of malnutrition in patients with cirrhosis and without clinically apparent malnutrition. Oral nutritional support, especially with products containing relatively high carbohydrate levels and low protein, may have a favorable effect on MELD scores.
