AB  - Chronic kidney disease (CKD) is a global health concern affecting approximately one billion individuals worldwide. End-stage kidney disease (ESKD), the most severe form of CKD, is
often accompanied by anemia. Peritoneal dialysis (PD), a common treatment for ESKD, utilizes the
peritoneum for solute transfer but is associated with complications including protein loss, including
transferrin (Tf) a key protein involved in iron transport. This study investigated Tf characteristics in
ESKD patients compared to healthy individuals using lectin microarray, spectroscopic techniques and immunocytochemical analysis to assess Tf interaction with transferrin receptors (TfRs). ESKD patients exhibited altered Tf glycosylation patterns, evidenced by significant changes in lectin reactivity compared to healthy controls. However, structural analyses revealed no significant differences in the Tf secondary or tertiary structures between the two groups. A functional analysis demonstrated comparable Tf-TfR interaction in both PD and healthy samples. Despite significant alterations in Tf glycosylation, structural integrity and Tf-TfR interaction remained preserved in PD patients. These findings suggest that while glycosylation changes may influence iron metabolism, they do not impair Tf function. The study highlights the importance of a glucose-free dialysis solutions in managing anemia exacerbation in PD patients with poorly controlled anemia, potentially offering a targeted therapeutic approach to improve patient outcomes.

AB  - As we already reported, fibrinogen fucosylation emerged as a prognostic marker of peritoneal
membrane function in end-stage renal disease (ESRD) patients on peritoneal dialysis. After a
follow-up period of 18 months, we estimated the ability of employed lectins, as well as other biochemical
parameters, to serve as mortality predictors in these patients. Following a univariate Cox
regression analysis, ferritin, urea clearance, residual diuresis, hyperglycemia, and an increase in the
signal intensity obtained with Galanthus nivalis lectin (GNL) emerged as potential mortality predictors,
but additional multivariate Cox regression analysis pointed only to glucose concentration
and GNL as mortality predictors. Higher signal intensity obtained with GNL in patients that died
suggested the importance of paucimannosidic/highly mannosidic N-glycan structures on fibrinogen
as factors that are related to unwanted cardiovascular events and all-cause mortality and can possibly
be seen as a prediction tool. Altered glycan structures composed of mannose residues are expected
to affect the reactivity of mannosylated glycoproteins with mannose-binding lectin and possibly
the entire cascade of events linked to this lectin. Since patients with ESRD are prone to cardiovascular
complications and the formation of atherosclerotic plaques, one can hypothesize that fibrinogen
with increasingly exposed mannose residues may contribute to the unwanted events.
