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  - Human serum tansferrin (hsTf) is a major circulatory protein crucial for the
transport/metabolism of Fe3+ ions. By sequestering and delivering ferric ions to target
tissues/cells hsTf maintains redox homeostasis. Oxidative stress (OS), one of the hallmarks
of (patho)physiological conditions, alters protein structure and function. The main role of
hsTf hinges on specific interaction with cellular Tf receptor (TfR) while other interactions
contribute to diverse functions. The aim of this study was to profile interacting partners of
hsTf in the samples of serum coming from patients diagnosed with a wide range of
pathological conditions with underlying OS status. Anti-hsTf pull-down samples were
analysed using mass spectrometry. Data went through analysis by appropriate
bioinformatic tools. Results reveal differences in expression of hsTf interacting proteins in
sample groups of patients suffering from kidney insufficiency subjected to dialysis
treatment (peritoneal-PD or hemo-HD) also with patients with gestational diabetes
compared to respective healthy sample groups. Colorectal cancer stage T3 versus T2 stage
shows an inverse distribution of expression profiles in comparison to healthy samples.
Most prominent differences are seen in hsTf interacting partners involved in the
complement and coagulation cascades and cholesterol metabolic pathways, suggesting a
multifaceted role of hsTf in these processes throughout the course of the disease.

AB  - In previous publications, we pointed out the importance of mannosylation of fibrinogen for the development of cardiovascular complications and fucosylation as a predictor of peritoneal membrane dysfunction in patients on peritoneal dialysis (PD). After a follow-up period of 30 months from the onset of the COVID-19 pandemic, we evaluated the significance of 1,25-dihydroxyvitamin D3 (calcitriol) therapy, primary disease, biochemical and hematologic analyzes, and previously performed glycan analysis by lectin-based microarray as predictors of mortality in this patient group. After univariate Cox regression analysis, diabetes mellitus (DM) and calcitriol therapy were found to be potential predictors of mortality. Additional multivariate Cox regression analysis confirmed that only DM was a predictor of mortality. Nevertheless, the use of calcitriol in therapy significantly reduced mortality in this patient group, as shown by the Kaplan–Meier survival curve. The presence of DM as a concomitant disease proved to be a strong predictor of fatal outcome in PD patients infected with SARS-CoV-2. This is the first study to indicate the importance and beneficial effect of calcitriol therapy on survival in PD patients with COVID-19 infection. In addition, this study points to the possibility that adverse thrombogenic events observed in PD patients during the pandemic may be caused by aberrant fibrinogen glycosylation.

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.
