Bacground/Aim. Hepcidin may play a pathogenetic role in iron metobolism disorders. The aim of this study was to determine the correlation between hepcidin concentration and parameters of iron metabolism in patients with different stage of chronic kidney disease (CKD). Methods. The study involved 104 patients with CKD: 64 on hemodialysis (HD) and 40 patients in pre-dialysis stadium (pre-HD) with adequate erythropoetin therapy and iron supplementation. The HD group was divided in four subgroups according to the level of serum ferritin (up to 100; 100-199; 200-499 and over 500 ng/mL). Parameters of anemia, iron status, inflamation and hepcidin level were evaluated. Results. The HD patients had a significantly lower eritrocyte count, erythrocytes indexes, hemoglobin and transferrin saturation and significantly higher iron, ferritin, hepcidin and total iron binding capacity (TIBC). The HD subgroups up to 199 ng/mL of serum feritin had lower high-sensitivity Creactive protein (hsCRP), iron and higher unbuffered iron binding capacity (UIBC), transferrin saturation and TIBC compared to the HD subgroups over 200 ng/mL. The lowest and the highest ferritin subgroups had the highest hepcidin level and it showed significant correlation with ferritin. Conclusion. Hepcidin may serve as a marker for better diagnosing and monitoring anemia and iron metabolism disorders in CKD.

The aim of the study is to investigate the diagnostic and prognostic value of integrated assessment of iron metabolism parameters in patients with spontaneous supratentorial intracerebral haemorrhage in acute period. Materials and methods. This prospective cohort study included 88 patients with spontaneous supratentorial intracerebral haemorrhage during the course of conservative treatment. Diagnosis was made based on the findings of clinical and neuro-imaging investigations. On the 1st day of the hospital admission fasting blood samples were taken. Levels of ferritin, hepcidin, iron, total iron binding capacity, unsaturated iron binding capacity and transferrin saturation were detected. Early neurological deterioration and unfavourable outcome of acute period of spontaneous supratentorial intracerebral haemorrhage as grading 4-6 scores by modified Rankin scale on the 21st day of the disease were chosen as clinical endpoints. Lethal outcome and unfavourable functional outcome were also recorded. Results. Three profile types of evaluated iron metabolism parameters were identified based on the cluster analysis in the patients with intracerebral haemorrhage. It has been found out the profile types with initial higher levels of serum hepcidin and ferritin in blood together with lower serum iron concentration (type II and particularly type III) are associated with more severe cerebral structures damage and increased risk of early clinical deterioration (relative risk (95% confidence interval) = 6,01 (1,54–24,86), р=0,0120) and unfavourable functional outcome of the disease (relative risk (95% confidence interval) = 4,45 (2,25–8,80), р˂0,0001). Conclusion. Profile type of serum hepcidin, ferritin and iron concentrations together with transferrin saturation in the patients with spontaneous supratentorial intracerebral haemorrhage on the 1st day of hospital admission is the informative integrated marker for short-term prognosis during the course of conservative treatment.

Abstract: Generally, chronic kidney disease (CKD) is associated with anemia due to decrease of erythropoietin that plays an important role in erythropoiesis. We reported a patient, 61-year-old male, suffered from chronic hemodialysis kidney disease with coinfection of viral hepatitis C, albeit, had normal hemoglobin and erythropoietin levels. The patient was diagnosed as CKD in March 2014 with laboratory results, as follows: hemoglobin (Hb) 9.9 g/dl; ureum 223 mg/dl; creatinine 7.5 mg/dl, and was confirmed with ultrasonography. The patient underwent hemodialysis and was treated with erythropoiesis stimulating agent (ESA) for the first time in April 2014. The last ESA was given in June 2015 and the laboratory results were serum iron 61 µg/dl, total iron binding capacity (TIBC) 173 µg/dl, ferritin 1431 ng/ml, and the qualitative anti HCV test was reactive. Afterwards, the patient was not treated with ESA anymore since his Hb level was normal without ESA or blood transfusion. Moreover, the erythropoietin (EPO) level was tested in December 2018 resulted within normal level. Until now, the patient is still undergoing hemodialysis without ESA or transfusion. This is a rare condition, and there is still no certain pathophysiology to explain. It is assumed that the mechanism is related to hepatitis C infection that stimulates the hepatocyte regeneration, therefore, the cells produce endogen erythropoietin resulting in increased Hb level.Keywords: chronic kidney disease (CKD), erythropoietin and hemoglobin level Abstrak: Umumnya penyakit ginjal kronik (PGK) disertai dengan anemia akibat penurunan eritropoietin yang berperan penting dalam proses eritropoiesis. Kami melaporkan kasus seorang laki-laki 61 tahun dengan PGK hemodialisis disertai ko-infeksi hepatitis C namun dengan kadar hemoglobin dan eritropoietin normal. Pasien dinyatakan PGK sejak Maret 2014 dengan kadar hemoglobin (Hb) 9,9 g/dL; ureum 223 mg/dl; kreatinin 7,5 mg/dl, dan didukung oleh hasil ultrasonografi. Pasien diberikan hemodialisis dan terapi ESA pertama kali pada bulan April 2014. Terapi ESA terakhir diberikan pada bulan Juni 2015 dengan hasil serum iron 61 µg/dl, total iron binding capacity (TIBC) 173 µg/dl, feritin 1431 ng/ml, dan anti HCV kualitatif reaktif, Setelah itu pasien tidak mendapat terapi ESA lagi karena pada pemeriksaan laboratorium ditemukan kadar hemoglobin normal tanpa terapi ESA atau transfusi darah. Pemeriksaan kadar eritropoietin (EPO) pada bulan Desember 2018 mendapatkan hasil 16 mIU/ml (nilai normal 2,6-18,5 mIU/ml). Hingga saat ini pasien masih rutin menjalani hemodialisis dan tidak pernah mendapat terapi ESA atau transfusi darah. Keadaan tersebut jarang ditemukan, dan tidak ada patofisologi yang pasti untuk menjelaskan penyebab keadaan tersebut. Mekanisme keadaan ini dikaitkan dengan infeksi hepatitis C yang merangsang regenerasi hepatosit, sehingga sel-sel tersebut menghasilkan hormon ertiropoietin endogen, dengan hasil akhir ialah peningkatan hemoglobin.Kata kunci: penyakit ginjal kronik (PGK), kadar eritropoietin dan hemoglobin

Background: Literature data indicate the benefit of magnesium (Mg) supplementation. The aim of this study was to examine the effect of short-term Mg supplementation on iron status in healthy female participants. Methods: One hundred healthy female students of the University of Belgrade - Faculty of Pharmacy participated in the study during eleven intervention days. Students ingested Mg preparations with the same dose of the active substance. The analysis included the measurement of serum iron, unsaturated iron binding capacity (UIBC), total iron binding capacity (TIBC), total Mg (tMg), ionized Mg (iMg), complete blood count, met-, carboxy- and oxy-haemoglobin (metHgb, COHgb, O2Hgb). Transferrin concentrations and the percentage of transferrin saturation (SAT) were calculated manually. The association among the analyzed biochemical parameters was examined using polynomial regression. A principal component analysis (PCA) was used for the evaluation of interdependence between the analyzed parameters. Results: A statistically significant trend for change in O2Hgb (%) by tertiles of iMg concentrations was found (P = 0.029). Serum tMg reached a significant positive correlation with the SAT at concentration levels greater than 0.9 mmol/L, after 11 days of intervention (R2=0.116). Ionized Mg in a concentration higher than 0.6 mmol/L is positively correlated with SAT and serum Fe (R2=0.214; 0.199, respectively). PCA revealed variability of 64.7% for two axes after 11 days. Conclusions: Mg supplementation leads to an improvement in certain iron status parameters even in individuals with optimal levels of these indices. However, caution should be exercised when supplementing Mg, and laboratory monitoring of the interaction is required.

The correlation of the length of time undergoing hemodialysis with the levels of hemoglobin, hematocrit, serum iron and total iron binding capacity in patients with chronic kidney disease at RSUD Prof. Dr. W. Z. Johannes Kupang. People with chronic kidney disease who are performing Hemodialysis suffer from anemia. Blood loss during the hemodialysis process is affected by frequent blood sampling for laboratory tests. To diagnose the occurrence of iron deficiency, anemia laboratory tests such as complete blood, serum iron (SI), TIBC, transferrin saturation, and serum ferritin can be conducted. The objective of this study is to determine the correlation between the length of undergoing Hemodialysis with the levels of Hemoglobin, Hematocrit, Serum Iron, and Total Iron Binding Capacity (TIBC) in patients with chronic kidney disease in RSUD Prof. Dr.W. Z Johannes Kupang. This study employed an anon-reactive research design or unobtrusive research based on secondary data derived from medical record records at RSUD Prof. Dr.W. Johannes in August - September 2019 on 92 hemodialysis patients who met the inclusion criteria. The collected data were calculated with the SPSS application, while the correlation analysis between variables was performed by administering a linear regression analysis test. Ninety-two (92) respondents were obtained by employing the purposive sampling technique. The majority of patients with chronic kidney disease undergoing Hemodialysis were men (57.6%) with ages 39 - 59 years (63.0%), and the majority of patients undergoing Hemodialysis in patients with chronic kidney failure (CKD) were <12 months (41.3%). It was discovered that there was no relationship between the length of Hemodialysis with hemoglobin, hematocrit, serum iron, and total iron-binding capacity levels in patients with chronic kidney disease (CKD).

Anemia, the common feature of Chronic Kidney Disease (CKD), is a multifactorial process due to disordered erythropoiesis and iron homeostasis. Determining the cause of anemia is important for adequate management. A bone marrow biopsy using Prussian Blue as the gold standard for diagnosis is invasive and more complicated to perform. Reticulocytes-Hemoglobin (Ret-He) a new parameter that indicates the hemoglobin content in reticulocytes is faster, easier, and less expensive. This study aimed to analyze the Ret-He in determining the iron status in patients with CKD. A cross-sectional study was held in the Clinical Pathology Laboratory of Dr. Wahidin Sudirohusodo Hospital Makassar during April-August 2016. Forty-five (45) samples were tested for iron serum (Fe), Total Iron Binding Capacity (TIBC), and Complete Blood Count (CBC) ordered by the physician. Reticulocytes-Hemoglobin was tested using the whole blood. Subjects were around the age of 19-71 years, no significant difference was found between numbers of males and females (46.6% and 53.3%). Hemoglobin median was 8 (5.0-15) g/dL, Fe 50 (6-177) U/mL, TIBC 183 (73-379), Transferrin Saturation (Tsat) 25 (5-95)%. Spearman correlation test method showed significant correlations between Ret-He and iron serum r=0.533, p <0.001, Ret-He and TIBC r=0.321 p=0.031 Ret-He and transferrin saturation r=0.416 p=0.019. The Mann-Whitney method showed no significant difference of Ret-He in both groups (Tsat <20% and >20%). There were significant correlations between Ret-He and iron, Ret-He and TIBC, Ret-He and transferrin saturation. A further study using larger samples is suggested to consider factors affecting the result of Ret-He.

Trypanosomiasis is one of the common parasitic diseases, which infects the dromedary camels and decreases the numbers of these animals in Iraq. To get the best knowledge of the changes of iron status in camels infected with trypanosomiasis, in an attempt to take advantage of these variables as markers for infection, we designed this study. The current study conducted in blood sample collection from155 dromedary camels, 33 were infected (21.29%), according to the status of infection with Trypanosoma evansi that depends on blood smear examination as a golden test. Results denote significant differences of infection ratio by sex and age, from total of 132 male tested, 29 (21.96%) infected, distributed into 12 (%41.37) of age ≤ 2 years and 17 (58.62) of ≥ 2 years. From 23 female tested, 4 (17.39%) were infected at age ≤ 2 years. Furthermore, the results of this study demonstrated significant (p˂0.05) decrease in total serum iron, transferrin saturation, ferritin, whereas increased in total iron binding capacity and unsaturated iron binding capacity in the infected male and female camels with different age. Analyzed data of iron status parameters denoted that the cutoff point test between sensitivity (97) and specificity (100) for serum iron is (≤67.26), for transferrin saturation is (≤17.23) between the sensitivity and specificity (100) and (≥378.66), for total iron binding capacity between the sensitivity and specificity (93.9 and 96.7) respectively. Also, the cutoff point test between the sensitivity (100) and specificity (96.7) for unsaturated iron binding capacity is (≥301.27) and ferritin concentration has a cutoff point is (≤ 249.88) for the sensitivity (100) and specificity (99.2). It could be concluded from what was stated in the results of the current study, that the measurement of the concentration of serum ferritin could be considered as a good marker for the T. evansi infection

The magnitude of chronic renal disease is enormous, as the prevalence of kidney failure is rising. Anaemia is a common complication of chronic kidney disease (CKD) that develops early in its course and becomes increasingly severe as the disease progresses. The aim is to evaluate the serum level of iron, Total Iron Binding Capacity (TIBC), transferrin saturation and ferritin in chronic kidney disease population in Zaria and control subjects. This study was conducted at ABUTH Zaria were 125 patients in various stages of CKD who presented at the nephrology clinic and equal number of apparently healthy age and sex matched controls were recruited. The mean (SD) age of patient and controls were 48 (14) years. These were made up of 53.6% males, and 46.4% females. Mean values of serum creatinine significantly higher in the patients (<0.0001). There was no significant difference in the mean values of iron (p=0.32) and TIBC (p=1.29) in both study groups. The patients had a significantly (p˂0.0001) higher mean value for ferritin and TSAT than the control group. There were higher serum creatinine and ferritin values in males than in females while higher serum TIBC, estimated creatinine clearance and iron were observed in females than males. Serum creatinine, ferritin and estimated creatinine clearance of male patients were found to be significantly higher with p-value of 0.002, 0.000 and 0.028 respectively than that of female patients. No significant differences were noted in serum levels of iron, TIBC and TSAT. Serum creatinine, ferritin and TSAT were found to be significantly elevated in CKD patients while serum Iron and TIBC were not.

Background Abnormalities of iron metabolism in pregnancy pose risks for maternal and fetal health. Robust reference intervals for iron metabolism indices have not been established in a pregnant Chinese population. The purpose of this study was to derive reference intervals for indices of iron metabolism during pregnancy in a Chinese population. Methods A total of 360 healthy pregnant women were recruited and divided into three groups of 120 by gestational age: first trimester (1–13 weeks), second trimester (14–27 weeks) and third trimester (≥28 weeks). An additional 120 healthy non-pregnant women were recruited as the non-pregnant control group. Serum ferritin was measured by electrochemiluminescence immunoassay. Serum iron and total iron-binding capacity were measured by a direct bathophenanthroline method. Transferrin saturation value was calculated with formula TS = SI/TIBC. The reference intervals were established using a non-parametric method. Results In first and second trimesters (combined), the reference intervals for serum ferritin, serum iron, total iron-binding capacity and transferrin saturation are 14.7–184.3 mg/L, 14.50–33.45 µmol/L, 36.53–68.81 µmol/L and 19.04–64.76%, respectively. In the third trimester, the reference intervals for serum ferritin, serum iron, total iron-binding capacity and transferrin saturation are 7.2–122.2 mg/L, 5.83–21.52 µmol/L, 49.40–122.76 µmol/L and 8.22–52.75%, respectively. Conclusion The reference intervals for iron metabolism indices for healthy pregnant Chinese women were established in accordance with CLSI C28-A3 guidelines. This will be a valuable tool for clinical practice and research.

Abstract After a brief review of physiological iron metabolism, we describe diagnostic tests for iron status and iron deficiency anemia in patients without chronic kidney disease (CKD) or inflammation. Thereafter we review the dysregulation of iron metabolism in CKD. Specific emphasis is placed on the role of the ‘inflammatory’ state that develops with the progression of CKD. It invokes changes in iron metabolism that are the exact opposite of those occurring during pure iron deficiency. As a result, transferrin saturation (TSAT) becomes a poorer index of iron availability to the bone marrow and serum ferritin no longer represents iron that can be used during erythropoiesis. We argue that serum iron may provide more information to guide iron therapy than TSAT. In other words, the emphasis on TSAT is misplaced. With the development of a number of hypoxia-inducible factor prolyl hydroxylase inhibitors, which restore iron metabolism toward the ‘physiologic state’, the iron indices indicating sufficient iron availability to avoid functional iron deficiency during therapy of CKD-associated anemia are likely to change. We summarize these changes in the section ‘A peek into things to come!’, citing the available data.
