Introduction. Studies have shown increased urine excretion of vitamin D-binding protein (VDBP) in patients with diabetic nephropathy (DN) resulting from postulated mechanisms linked to renal tubular damage. In this study, we evaluate the utility of VDBP clearance ratio as a novel determinant of glycemic status, DN, and other diabetes-associated complications.Methods. Levels of vitamin D, HbA1c, serum, urine concentrations of VDBP, and creatinine were measured in 309 subjects. The ratio of urine microalbumin to creatinine was determined to categorize subjects as normoalbuminuric (NAO), microalbuminuric (MIA), and macroalbuminuric (MAA). The VDBP clearance ratio was calculated.Results. Mean VDBP clearance ratios in NAO, MIA, and MAA were 0.7, 4, and 15, respectively. Significant positive correlations of VDBP clearance ratio were found with age, WC, SBP, DBP, TG, glucose, HbA1c, urine VDBP, urine microalbumin, and urine microalbumin/creatinine, and a significant negative correlation was found with the steady-state estimate of beta cell function (B%). Receiver operating curve (ROC) analyses of the use of VDBP clearance ratio for detection of albumin status shows a value of 0.81 for the area under the curve.Conclusions. The strong associations of VDBP clearance ratio with glycemic control and diabetes-associated complications suggest that this index could play a wider role in detection and/or pathogenesis and complications of diabetes.

AbstractThe role of vitamin D in innate and adaptive immunity is recently under investigation. In this study we explored the potential association of genetic variances in vitamin D pathway and infections in infancy. Τhis prospective case–control study included infants 0–24 months with infection and age-matched controls. The single nucleotide polymorphisms of vitamin D receptor (VDR) gene (BsmI, FokI, ApaI, TaqI), vitamin D binding protein (VDBP) (Gc gene, rs7041, rs4588) and CYP27B1 (rs10877012) were genotyped by polymerase chain reaction-restriction fragment length polymorphism. In total 132 infants were enrolled, of whom 40 with bacterial and 52 with viral infection, and 40 healthy controls. As compared to controls, ΤaqI was more frequent in infants with viral infection compared to controls (p = 0.03, OR 1.96, 95% CI 1.1–3.58). Moreover, Gc1F was more frequent in the control group compared to infants with viral infection (p = 0.007, OR 2.7, 95% CI 1.3–5.6). No significant differences were found regarding the genetic profile for VDR and VDBP in infants with bacterial infection compared to the controls and also regarding CYP27B1 (rs10877012) between the studied groups. Genotypic differences suggest that vitamin D pathway might be associated with the host immune response against viral infections in infancy.

Abstract Objectives There is no reliable and valid biomarker to identify Irritable bowel syndrome (IBS) and its subtypes. The aim of this study is to explore potential serum biomarkers that may be associated with IBS subtypes, particularly in the vitamin D pathway. Methods The study population comprised 75 IBS patients and 79 controls. Patients divided into IBS subtypes. Routine biochemical parameters, 25-OH-vitamin D, vitamin D binding protein (VDBP) and vitamin D receptor (VDR) serum levels were compared between IBS subtypes and controls. Factors related to IBS subtypes were examined by multivariate logistic regression analysis. Results Vitamin D levels were lower; VDBP and VDR were higher in all IBS patients than in controls (p<0.001; 0.047 and 0.029, respectively). According to logistic regression analysis, VDBP was a disease-related parameter as much as vitamin D in all IBS subtypes. C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR) were higher especially in diarrhea-dominant IBS (IBS-D) (p=0.041; 0.046) and vitamin B12 were significantly lower in constipation-dominant IBS (IBS-C) (p=0.001). Conclusions Increased VDBP levels were associated with all IBS subtypes. Patients, especially in IBS-D, had higher serum levels of VDBP, CRP and ESR. Vitamin B12 deficiency, which we consider as a result of the disease, was more common in IBS-C.
