Objective: Iron deficiency (ID) is a frequent complication in end stage renal insufficiency. These patients have to be diagnosed and treated to reduce the prevalence of anemia. Functional iron deficiency (FID) is a situation that can disrupt biochemical iron tests and mask an eventual association with ID. In this study, we tried to prove the ability of extended parameters of red cells and reticulocytes to diagnose ID without being influenced by FID. Design and methods: 164 chronic hemodialysis patients (CHP) in end stage renal disease were enrolled. Research parameters of red cells and reticulocytes determined on ADVIA 2120i were studied in the diagnosis of ID associated or not with chronic inflammation. Results: Parameters such as corpuscular hemoglobin of mature red cells (CHm), corpuscular hemoglobin of reticulocytes (CHr), cellular concentration of hemoglobin in mature red cells (CHCMm), cellular concentration of hemoglobin in reticulocytes (CHCMr) and percentage of microcytic and hypochromic red cells (HYMI) showed a high sensitivity to diagnose ID. However, the distinction of combined iron deficiency (CID) from other entities was not possible with all parameters. In chronic inflammatory states, the decrease of CHm, CHCMm and CHCMr with the rise of percentage hypochromic mature red cells (HYPOm) and reticulocytes (HYPOr) is in favor of CID. So, determination of inflammatory state is needed to complete research parameters of blood count in CHP. Conclusion: Extended erythrocyte and reticulocyte parameters can be useful to check iron status in CHP.

Hemodialysis is the most used renal replacement therapy for children in Morocco. The objective of this study was to determine the prevalence of patients who started hemodialysis in childhood and study their characteristics and specificities of their care. For this we conducted a multicentric descriptive cross-sectional study of all chronic hemodialysis patients who started dialysis in pediatric age, in hemodialysis centers in four of the sixteen regions of Morocco. We collected 2066 patients undergoing dialysis in 39 hemodialysis centers; from these, only 72 patients (3.48%) started hemodialysis in childhood. The average age of patients was 20.64 ± 6.5 years with a sex ratio of 1.9. Duration of dialysis was 78.2 ± 56 months. The cause of end stage renal disease was urological abnormalities in 18% of cases and glomerulopathy in 12.5% of cases; however, it remains unknown in half of the patients. Over 18 years, 74% of patients are without profession, it is active in 13% of cases, and pursuing studies are only in 13% of cases. Patients under 5 years and those with a low weight are rarely taken care of in chronic hemodialysis with little individualization of prescription. Greater attention should be paid to renal transplantation that is desired by the majority of these patients (92%).

Background: While COVID-19 in chronic hemodialysis patients has high mortality and the pandemic will not end in the near future, effective follow up strategies should be implemented for these patients. Surgeries have been triaged according to their level of urgencies and arteriovenous fistula (AVF) operations were among elective surgeries. This study aimed to analyze the effect of vascular access on the outcomes of hemodialysis patients who had COVID-19. Methods: One hundred four hemodialysis patients who had COVID-19 were retrospectively analyzed. Seventy-two of them had AVF as the vascular access while 32 of them had tunneled catheters. Inflammatory markers and outcomes of patients with AVFs and catheters were compared. A logistic regression analysis was performed in order to define factors that contribute to better outcomes in hemodialysis patients. Results: COVID-19 had high mortality rate in hemodialysis patients (36.5%). Patients with catheters have higher peak ferritin levels ( p = 0.02) and longer hospital stay ( p = 0.00). Having AVF as the vascular access (OR = 3.36; 95% CI: 1.05–10.72; p = 0.041) and using medium cut-off dialyzers (OR = 7.99; 95% CI: 1.53–41.65; p = 0.014) were related to higher survival of the patients. COVID severity was inversely proportional to the survival ( p = 0.000) Conclusions: AVFs contribute to higher survival of hemodialysis patients with COVID-19. Even in the pandemic era, end stage renal disease patients should be given the opportunity to have their vascular access properly created.

SummaryActivated platelets may engage in dynamic interplay with other blood cells. We examined the evidence for platelet activation and the formation of platelet-erythrocyte aggregates in chronic hemodialysis patients. Circulating activated platelets (P-selectin/CD63-positive platelets) were higher than normal controls (p <0.001) and further increased during hemodialysis sessions, the increase being higher when patients were dialyzed with cellulosic than with synthetic membranes. We found direct evidence of uremic platelet-erythrocyte adherence in vitro and increased levels of circulating platelet-erythrocyte aggregates in dialysis patients, which represents a new observation in uremia. Platelet-erythrocyte aggregates were subject to further increase during hemodialysis, and again higher levels were found with cellulosic than synthetic membranes. This phenomenon was reproduced in vitro by both ADP and PAF, but not by either complement factor C3a or by heparin concentrations corresponding to those used for clinical hemodialysis. We conclude that platelet-erythrocyte aggregates occur in hemodialysis patients probably owing to a primary platelet activation mechanism.

Background/Aims: Depression is common in patients with end-stage renal disease (ESRD) on hemodialysis (HD). Although, depression is associated with mortality, the effect of depression on in-hospital outcomes has not been studied as yet. Methods: We analyzed the National Inpatient Sample for trends and outcomes of hospitalizations with depression in patients with ESRD. Results: The proportion of ESRD hospitalizations with depression doubled from 2005 to 2013 (5.01-11.78%). Hospitalized patients on HD with depression were younger (60.47 vs. 62.70 years, p < 0.0001), female (56.93 vs. 47.81%, p < 0.0001), white (44.92 vs. 34.01%, p < 0.0001), and had higher proportion of comorbidities. However, there was a statistically significant lower risk of mortality in HD patients within the top 5 reasons for admissions. Conclusion: There were significant differences in demographics and comorbidities for hospitalized HD patients with depression. Depression was associated with an increased rate of adverse effects in discharged patients, and decreased in-hospital mortality.

BACKGROUND: Anemia is one of the most common complications in end-stage renal disease (ESRD) patients. Hepcidin is a hormone that regulates iron homeostasis in patients with ESRD. Carnitine deficiency is commonly seen in hemodialysis (HD) patients. AIM: This study aimed to investigate the relationship between hepcidin and inflammatory and other anemia markers in children with ESRD and to evaluate the association of carnitine deficiency with anemia in these patients. SUBJECTS AND METHODS: Thirty pediatric patients with ESRD undergoing HD, and thirty healthy, age- and sex-matched children served as controls were included in the study. Serum levels hepcidin, iron status, high-sensitivity C-reactive protein, and total carnitine were measured. RESULTS: Statistically significant increases in serum levels of hepcidin (100.7 ± 0.99 ng\ml vs. 77.43 ± 0.8 ng\ml, p = 0.000), was found in HD children as compared to healthy controls. Statistically significant increase in serum levels of hs-CRP (3.94 ± 0.19 mg/l vs. 1.36 ± 0.07 mg/l, p = 0.04) was found in HD children as compared to healthy controls. However, serum levels of carnitine (29.59 ± 2.46 μmol/L vs. 36 ± 2.39 μmol/L, p = 0.000) showed statistically significant decreases in HD children as compared to healthy controls positive correlation was found between hepcidin and hs-CRP (r = 0.059, p = 0.042). Furthermore, a positive correlation was present between serum carnitine levels and serum iron levels (r = 0.651, p = 0.042). CONCLUSION: Serum hepcidin may be a more useful biomarker of functional iron deficiency in children on HD. The efficacy of carnitine treatment for children on HD with carnitine deficiency and its effect on anemia needs to be studied.

Background: Due to the premium rate of Chronic Kidney Disease, we have increased our knowledge with respect to diagnosis and treatment of Bone Mineral Disease (BMD) in End- Stage Renal Disease (ESRD). Currently, various treatment options are available. The medication used for Secondary Hyper-Parathyroidism gives promising results in the regulation of Ca, P and Parathormone levels, improving the quality of life. The aim of the present study was to investigate the relation of cinacalcet administration to not only parathormone, Ca and P but also to anemia parameters such as hematocrit and hemoglobin. Materials and Methods: retrospective observational study was conducted in a Chronic Hemodialysis Unit. One-hundred ESRD patients were recruited for twenty-four months and were evaluated on a monthly rate. Biochemical parameters were related to medication prescribed and the prognostic value was estimated. Cinacalcet was administered to 43 out of 100 patients in a dose of 30-120 mg. Results: Significant differences were observed in PTH, Ca and P levels with respect to Cinacalcet administration. Ca levels appeared to be higher at 30mg as compared to 60mg cinacalcet. Furthermore, a decreasing age-dependent pattern was observed with respect to cinacalcet dosage. A positive correlation was observed between Dry Weight (DW) and cinacalcet dose. Finally, a positive correlation between Hematocrit and Hemoglobin and cinacalcet was manifested. Conclusions: Cinacalcet, is a potential cardiovascular and bone protective agent, which is approved for use in ESRD patients to assist SHPT. A novel information was obtained from this study, regarding the improvement of the control of anemia.

AbstractCohort studies often provide a large array of data on study participants. The techniques of statistical learning can allow an efficient way to analyze large datasets in order to uncover previously unknown, clinically relevant predictors of morbidity or mortality. We applied a combination of elastic net penalized Cox regression and stability selection with the aim of identifying novel predictors of mortality in a cohort of prevalent hemodialysis patients. In our analysis we included 475 patients from the “rISk strAtification in end-stage Renal disease” (ISAR) study, who we split into derivation and confirmation cohorts. A wide array of examinations was available for study participants, resulting in over a hundred potential predictors. In the selection approach many of the well established predictors were retrieved in the derivation cohort. Additionally, the serum levels of IL-12p70 and AST were selected as mortality predictors and confirmed in the withheld subgroup. High IL-12p70 levels were specifically prognostic of infection-related mortality. In summary, we demonstrate an approach how statistical learning can be applied to a cohort study to derive novel hypotheses in a data-driven way. Our results suggest a novel role of IL-12p70 in infection-related mortality, while AST is a promising additional biomarker in patients undergoing hemodialysis.
