Chronic Obstructive Pulmonary Disease (COPD) is a chronic inflammatory airway disease punctuated by exacerbations (AECOPD). Subjects with frequent AECOPD, defined by having at least two exacerbations per year, experience accelerated loss of lung function, deterioration in quality of life and increase in mortality. Fibroblast growth factor (FGF)23, a hormone associated with systemic inflammation and altered metabolism is elevated in COPD. However, associations between FGF23 and AECOPD are unknown. In this cross-sectional study, individuals with COPD were enrolled between June 2016 and December 2016. Plasma samples were analyzed for intact FGF23 levels. Logistic regression analyses were used to measure associations between clinical variables, FGF23, and the frequent exacerbator phenotype. Our results showed that FGF23 levels were higher in frequent exacerbators as compared to patients without frequent exacerbations. FGF23 was also independently associated with frequent exacerbations (OR 1.02; 95%CI 1.004–1.04; p = 0.017), after adjusting for age, lung function, smoking, and oxygen use. In summary, FGF23 was associated with the frequent exacerbator phenotype and correlated with number of exacerbations recorded retrospectively and prospectively. Further studies are needed to explore the role of FGF 23 as a possible biomarker for AECOPD to better understand the pathobiology of COPD and to help develop therapeutic targets.

Fibroblast Growth Factor-23 and Hypophosphatemia in Chronic Obstructive Pulmonary Disease PatientsImpaired serum phosphate levels may contribute to respiratory muscle weakness that further negatively impacts Chronic Obstructive Pulmonary Disease (COPD) patients. Recently, Fibroblast Growth Factor 23 (FGF-23) has been shown to play an important role in the regulation of body phosphate. The current study includes 2 groups: 70 COPD patients and 34 control subjects. Blood samples were taken for a panel of routine lab tests. FGF-23 was measured using a commercially available ELISA kit. Plasma FGF-23 levels were significantly higher in the patient group compared to the control group (P=0.000). Tubular maximum absorption of phosphate was significantly reduced in COPD patients compared to the control group (P=0.04). Plasma FGF-23 negatively correlated with FEV1 and serum albumin. Elevated plasma FGF-23 levels found in COPD patients correlated with disease severity and may represent an additional factor causing low serum phosphate.

Measured Volume

Introduction: Volume overload is a known risk factor for cardiovascular disease and stroke in hemodialysis patients. The use of fibroblast growth factor 23 (FGF23) as a volume overload marker has been validated in multiple studies. Objectives: This is a prospective cross-sectional study considering the association between FGF23 and bioimpedance-measured volume overload in hemodialysis patients. Patients and Methods: Bioimpedance analysis was performed on 43 hemodialysis patients at the end of hemodialysis to evaluate the remaining volume overload and serum FGF23 was measured before hemodialysis. Results: The results indicated no significant correlation between mean serum FGF23 levels and volume overload in hemodialysis patients (P=0.824). Conclusion: Although this study did not show any association between volume overload and FGF23, further studies are needed to define the role of FGF23 as a volume overload marker.

The Relationship

The relationship between soluble Klotho (s-Klotho) levels, fibroblast growth factor 23 (FGF23) levels, and albuminuria in patients with diabetic chronic kidney disease (CKD) remains unclear. A total of 109 patients with type 2 diabetes (mean age 61.63±9.77 years), at the outpatient clinic of the Antalya Research and Training Hospital Nephrology Unit between January and June 2014, as well as 32 healthy controls (mean age 49.53±7.32 years) were enrolled for this cross-sectional study. Patients were classified into three groups according to their urinary albumin creatinine ratio (UACR), normoalbuminuria (UACR<30 mg/g), microalbuminuria (UACR 30–300 mg/g), and macroalbuminuria (UACR>300 mg/g). The blood was analyzed for FGF23, s-Klotho, parathyroid hormone (PTH), P, Ca, creatinine, and 25-hydroxyvitamin D3 (25hD) levels. Creatinine, s-Klotho, FGF23, and PTH levels were significantly higher and 25hD levels were significantly lower in the patient group than in the healthy controls (p<0.001). Between the groups according to UACR, 1-way analysis of variance revealed statistically significant differences for creatinine (p<0.001), 25hD (p<0.001), PTH (p=0.002), Ca (p=0.002), and albumin levels (p<0.001). A statistically significant positive correlation was found between s-Klotho and FGF23 (r=0.768; p=0.001), and between FGF23 levels and UACR (r=0.768; p=0.001). In conclusion, the results of the present study suggest that s-Klotho levels are significantly elevated in patients with diabetes and s-Klotho levels decreased with increasing albumin excretion in our patients despite a reduction in estimated glomerular filtration rate.

Abstract Introduction It is believed that fibroblast growth factor 23 (FGF23) can become an early biomarker of chronic kidney disease progression. Data on FGF23 age dependency are inconsistent. We present the results of the cross-sectional study concerning FGF23 levels in healthy Polish children. Material and methods This study was conducted in 121 children aged 0–18 years. Kidney function and intact FGF23 levels in serum were assessed. Differences between age groups and according to gender were analysed. Results The difference in FGF23 between age groups and according to gender was statistically insignificant. In the youngest and the oldest group, a trend to higher FGF23 levels was observed. FGF23 level in girls tended to be higher than boys, apart from the age group between 1 and 4 years. There was a negative correlation between eGFR and FGF23 (r = −0.26, p < 0.05) – strong in girls (r = −0.38, p < 0.05), but not in boys. In each age group, we found no significant correlation between eGFR and FGF23. Conclusions Our study supports the evidence that the FGF23 level in paediatric population is not age or sex dependent. The results can serve as a reference point under clinical conditions and for other studies on the topic.

Advanced glycation end products (AGEs) may induce cardiac remodeling in kidney disease by promoting fibroblast growth factor 23 (FGF-23) expression. Since AGEs are increased in diabetes mellitus (DM), our first aim was to evaluate the existence of any potential association between AGEs, FGF-23, inflammation, and increased cardiovascular risk in DM patients on dialysis (CKD-G5D). Secondarily, we explored the potential role of the soluble receptor for AGEs (sRAGE) as a marker of heart failure. Levels of glycated albumin (GA), sRAGE, c-terminal FGF-23 (cFGF-23), brain natriuretic peptide (BNP), and inflammatory mediators were compared between DM and non-DM CKD-G5D patients. The levels of sRAGE, cFGF-23, BNP, and proinflammatory markers were over the ranges of normality in both DM and non-DM groups. Only GA and sRAGE levels were increased in DM compared to non-DM patients. Plasma levels of sRAGE and CRP were the only independent predictors of BNP concentration. In conclusion, in DM CKD-G5D patients, sRAGE appeared to be a marker of cardiac remodeling. Indeed, its increase could be a potential protective mechanism against the increased risk of cardiovascular complications related to AGEs and inflammation. The causal relationship between sRAGE and cardiovascular risk in these patients needs to be further confirmed by mechanistic studies.
