Blood samples for FGF-23 were obtained
from a subgroup of 8 patients from one satellite dialysis centre. Middle- (β2-microglobulin and FGF-23) and small-molecule removal were compared as reduction ratios for each compound. Paired t-tests were performed for statistical analysis. Results: β2-microglobulin concentrations fell more with HDF than with conventional HD (HD 66.44%, HDF15L 76.48%, HDF25L 82.05%, p < 0.0001 for all comparisons between each modality). FGF-23 testing is currently in progress. No significant changes were observed in small molecule clearance (K+, PO4−, urea). Conclusions: Consistent with previous reports, HDF with higher convection volumes produces the greatest fall in β2-microglobulin concentrations. This and other middle molecule removal may contribute
to the mortality benefits offered by HDF compared Navitoclax with https://www.selleckchem.com/products/CAL-101.html conventional HD.

But a lot of serum proteins are theoretically removed along with the elimination of middle-large molecules. Since total complement hemolytic activity (CH50) can be closely related to nutrition status and represents early turn-over complement components, we evaluated the association of CH50 and nutrition status after the transition to on-line HDF from HD. Methods: Twenty patients who had transited from HD to on-line HDF in December 2012 were enrolled. We evaluated blood samples three times at 0 month, 3 months and 9 months after the transition, and collected the yearly number of administration. Results: All patients were divided into two groups; group A (n = 10)
significantly increased in CH50 at 9 months after the transition and group B (n = 10) significantly decreased. Serum urea nitrogen (SUN), serum creatinine (sCre) and total cholesterol (T-chol) in group B at 0 month were significantly lower than in group A. SUN, sCre, T-chol, LDL-cholesterol, urea acid (UA), potassium check (K), serum total protein (TP) and serum albumin (Alb) in group B at 9 months after the transition were significantly lower than in group A. In group A, TP significantly increased toward 9 months after the transition. In group B, TP, Alb, UA and HDL-cholesterol significantly decreased toward 9 months after the transition. Additionally, CH50 had already significantly increased toward 3 months after the transition in group A. On the other hand, in group B, CH50 showed no change until 3 months after the transition but significantly decreased after that.
