Abstract Background Anemia is a severe complication of chronic kidney disease (CKD) that is seen in more than 80% of patients with impaired renal function. Although there are many mechanisms involved in the pathogenesis of anemia of renal disease, the primary cause is the inadequate production of erythropoietin by the damaged kidneys. Aim of the work to assess hepcidin level in non dialysis patients (CKD stage 4 &5) treated from Hepatitis C virus and its relation to iron parameters. Patients and Methods This study was conducted on 20 CKD patients (stage 4 and 5) treated from hepatitis C virus. All candidates included in this study subjected to careful history taking, full clinical examination and investigations (including complete blood count, renal chemistry, HCVAb, serum iron, total iron binding capacity, TSAT%, ferritin and hsCRP. Serum hepcidin was analyzed by ELISA technique. Results Serum hepcidin was 26.35±7.26; 40% in stage III, 37.8% in stage IV and 22.2% in stage V. There was statistically significant difference between GFR stages according to Hb., Drug intake ACE inhibitor/ARB, Plt., Creatinine, BUN, Iron, TIBC, Ferritin, T SAT%, CRP and Serum Hepcidin. We showed significant correlations between serum hepcidin and TIC, Iron, TIBC, Ferritin and TSAT%. Conclusion Median hepcidin value is elevated in nondialysis CKD patients due to increased inflammation and decreased clearance of hepcidin. Furthermore, iron status modifies serum hepcidin level and its association with Hb. Increased hepcidin level leads to iron-restricted erythropoiesis and recombinant human EPO (rhEPO) resistance by inhibiting iron absorption from gut and iron recycling from macrophages. Hence, elevated hepcidin can predict need for parenteral iron to overcome hepcidin-mediated iron-restricted erythropoiesis and need for relatively higher rhEPO doses to suppress hepcidin.

Abstract Background Anemia is a severe complication of chronic kidney disease (CKD) that is seen in more than 80% of patients with impaired renal function. Hepcidin, an acute phase reactant protein produced in the liver, is a key regulator of iron homeostasis. Aim of the Work to assess hepcidin level in 45 non-dialysis patients (CKD stage IV and V with negative virology) and its relation to iron parameters. Patients and Methods A cross sectional study was conducted at Nasser Institute for Treatment and Research on 45 patients with chronic kidney disease stage IV and V. All patients included in this study were subjected to the following: Careful history taking, full clinical examination and proper laboratory investigations. Results A statistically significant difference was found between CKD stage 4 and stage 5 according to Hb., iron, TIBC, Frerretin, serum and CRP. Also, there was a significant positive correlation of serum hepcidin with serum ferretin and hsCRP, while Hb and iron were significantly negatively correlated with hepcidin. We found statistically significant decrease in Hb level, serum Iron level, and TIBC in CKD stage 5 less than stage 4. We found statistically significant increase in Hepcidin level, serum ferritin, and hsCRP in CKD stage 5 more than stage 4. We found statistically significant Positive correlation between serum hepcidin with serum ferretin among patients with CKD stage 4 and 5. We found statistically significant Positive correlation between serum hepcidin with hsCRP among patients with CKD stage 4 and 5. We found statistically significant negative correlation between serum hepcidin with Hb among patients with CKD stage 4 and 5. A statistically significant Positive correlation between serum hepcidin with serum Iron among patients with CKD stage 4 and 5. Also we reported a statistically non-significant negative correlation between serum hepcidin and TIBC. Conclusion Elevated hepcidin can predict the need for parenteral iron to overcome hepcidin-mediated iron-restricted erythropoiesis and need for relatively higher rhEPO doses to suppress hepcidin in CKD patients with negative viral markers.

Reticulocyte hemoglobin equivalent (RET-He) represents hemoglobin content in reticulocyte. Reticulocyte hemoglobin equivalent test can be used to asses iron status of chronic kidney disease (CKD). Iron deficiency happens in 40% CKD and could lead to anemia manifestation. Level of RET-He gives real-time assesment of iron availability for hemoglobin production and the level will getting lower when iron storage for erythropoiesis decreasing. Reticulocyte hemoglobin equivalent is more stabil than feritin and transferin saturation in assessing iron status. Aim of this study is to determine RET-He level in patients with CKD stage IV and V. This study is  a cross sectional descripstive study. Subjects were 96 CKD stage IV and V patients that met inclusion and exclusion criterias. Subjects conducted blood tests at Central Laboratory Installation Dr. M. Djamil Hospital Padang from July to September 2020. Examination of RET-He level was analyzed by Sysmex XN-1000 flowcytometry fluorescense method. Data was presented in frequency distribution table. The RET-He level below cutoff (<29,2 pg) indicates the need for iron suplementation therapy for CKD stage IV and V patients. Samples with RET-He level below cutoff were 48 (50%) and 48 (50%) were above cutoff.

BACKGROUND: An Arteriovenous fistula (AVF) is a creation of the natural blood vessels. It is a “gate of life” for the patients on hemodialysis. AIM: The study aimed to analyze the predictors for primary failure of AVF such as gender, age, number and location of AVF, and primary renal disease in patients with chronic kidney disease (CKD) stage 4/5.MATERIAL AND METHODS: The medical records of 178 created arteriovenous fistulae in patients with CKD stage 4/5, were retrospectively studied. Primary failure of AVF was defined as thrombosis or inability for cannulation of AVF within 3 months. Adequate maturation of AVF was defined as successful cannulation of AVF treatment and blood flow of > 600 ml/min.RESULTS: The mean age of the patients was 59.75 ± 14.65 years, and 65.16% (116/178) were men. Adequate maturation of AVF was achieved in 83.71% (149/178). Primary failure of AVF occurred in 16.29% (29/178) of the created fistulae, while 10.11% (18/178) had early thrombosis. The distal arteriovenous fistulae were significantly more frequently created in male patients (51 vs 18; p = 0.015). The female patients were significantly older than the male patients (63.27 vs 57.86 years; p = 0.018). CONCLUSION: Male gender was associated with better maturation of AVF. The age, number and location of AVF, and primary renal disease in patients with CKD stage 4/5 were not associated with primary failure of AVF.

Background: Increases in measured inulin clearance, measured creatinine clearance, and estimated glomerular filtration rate (eGFR) have been observed with bardoxolone methyl in 7 studies enrolling approximately 2,600 patients with type 2 diabetes (T2D) and chronic kidney disease (CKD). The largest of these studies was Bardoxolone Methyl Evaluation in Patients with Chronic Kidney Disease and Type 2 Diabetes (BEACON), a multinational, randomized, double-blind, placebo-controlled phase 3 trial which enrolled patients with T2D and CKD stage 4. The BEACON trial was terminated after preliminary analyses showed that patients randomized to bardoxolone methyl experienced significantly higher rates of heart failure events. We performed post-hoc analyses to characterize changes in kidney function induced by bardoxolone methyl. Methods: Patients in ­BEACON (n = 2,185) were randomized 1: 1 to receive once-daily bardoxolone methyl (20 mg) or placebo. We compared the effects of bardoxolone methyl and placebo on a post-hoc composite renal endpoint consisting of ≥30% decline from baseline in eGFR, eGFR <15 mL/min/1.73 m2, and end-stage renal disease (ESRD) events (provision of dialysis or kidney transplantation). Results: Consistent with prior studies, patients randomized to bardoxolone methyl experienced mean increases in eGFR that were sustained through study week 48. Moreover, increases in eGFR from baseline were sustained 4 weeks after cessation of treatment. Patients randomized to bardoxolone methyl were significantly less likely to experience the composite renal endpoint (hazards ratio 0.48 [95% CI 0.36–0.64]; p < 0.0001). Conclusions: Bardoxolone methyl preserves kidney function and may delay the onset of ESRD in patients with T2D and stage 4 CKD.

Abstract Background Lithium-induced nephropathy is a known long-term complication, sometimes limiting the use of lithium as mood stabilizer. The aim of this study is to establish the incidence of chronic kidney disease and the rate of decline of renal function in patients using lithium and to identify risk factors. Methods We selected 1012 patients treated with lithium from the laboratory database of the Antes Centre for Mental Health Care spanning a period from 2000 to 2015. Serum lithium and creatinine concentrations were retrieved and eGFR was calculated using the 4-variable CKD-EPI formula. We calculated the incidence of renal insufficiency and the rate of decline. We compared patients with and without chronic kidney disease (CKD) stage 3 regarding duration of lithium exposure. Results Incidence of chronic kidney disease was 0.012 cases per exposed patient-year. Average decline of eGFR was 1.8 ml/min/year in patients who developed chronic kidney disease stage 3. Incidence of chronic kidney disease stage 4 was only 0.0004 per patient year. No cases of end stage renal disease were found in this cohort. Odds of reaching chronic kidney disease stage 3 were increased with longer duration of lithium exposure. Conclusions The use of lithium seems to be related to a higher incidence of chronic kidney disease. Longer duration of lithium exposure significantly increased the risk of renal failure.
