Zhang J, Yan B, Shi X. Association of iron overload with infectious complications in liver transplant recipients: a systematic review and meta-analysis. J Int Med Res 2024; 52:3000605241232920. [PMID: 38518199 PMCID: PMC10960351 DOI: 10.1177/03000605241232920] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/27/2023] [Accepted: 01/29/2024] [Indexed: 03/24/2024] Open
Abstract
OBJECTIVE This study was performed to examine the possible association of iron overload with infectious complications and survival among liver transplant recipients. METHODS We conducted a systematic review and meta-analysis of studies published in the PubMed, Embase, Web of Science, and Cochrane Library databases up to September 2022. Hazard ratios (HRs) and 95% confidence intervals (CIs) were extracted to estimate the association of iron overload with infectious outcomes and overall survival after liver transplantation. RESULTS Eight studies involving 2817 recipients met the inclusion criteria. Iron overload was strongly associated with an increased risk of infection after liver transplantation (HR, 1.66; 95% CI, 1.03-2.68). An increase in the serum ferritin level was associated with an increased risk of infection after liver transplantation (HR, 1.44; 95% CI, 1.09-1.91). Iron overload was a significant predictor of worse overall survival (HR, 1.35; 95% CI, 1.11-1.64). In addition, a high serum ferritin level was significantly associated with an increased risk of death (HR, 1.34; 95% CI, 1.10-1.64). CONCLUSION Iron overload may be associated with a higher risk of infectious complications and a worse prognosis among liver transplant recipients.

Implications of anaemia and response to anaemia treatment on outcomes in patients with cirrhosis. JHEP Rep 2023; 5:100688. [PMID: 36926273 PMCID: PMC10011825 DOI: 10.1016/j.jhepr.2023.100688] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/03/2022] [Revised: 12/29/2022] [Accepted: 01/12/2023] [Indexed: 01/30/2023] Open
Abstract
Background & Aims Anaemia is frequently observed in patients with cirrhosis and was identified as a predictor of adverse outcomes, such as increased mortality and occurrence of acute-on-chronic liver failure. To date, the possible effects of iron supplementation on these adverse outcomes are not well described. We therefore aimed to assess the role of iron supplementation in patients with cirrhosis and its capability to improve prognosis. Methods Laboratory diagnostics were performed in consecutive outpatients with cirrhosis admitted between July 2018 and December 2019 to the University Hospital Essen. Associations with transplant-free survival were assessed in regression models. Results A total of 317 outpatients with cirrhosis were included, of whom 61 received a liver transplant (n = 19) or died (n = 42). In multivariate Cox regression analysis, male sex (hazard ratio [HR] = 3.33, 95% CI [1.59, 6.99], p = 0.001), model for end-stage liver disease score (HR = 1.19, 95% CI [1.11, 1.27], p <0.001) and the increase of haemoglobin levels within 6 months (ΔHb6) (HR = 0.72, 95% CI [0.63, 0.83], p <0.001) were associated with transplant-free survival. Regarding the prediction of haemoglobin increase, intake of rifaximin (beta = 0.50, SD beta = 0.19, p = 0.007) and iron supplementation (beta = 0.79, SD beta = 0.26, p = 0.003) were significant predictors in multivariate analysis. Conclusions An increase of haemoglobin levels is associated with improvement of transplant-free survival in patients with cirrhosis. Because the prediction of haemoglobin increase significantly depends on rifaximin and iron supplementation, application of these two medications can have an important impact on the outcome of these patients. Impact and implications Anaemia is very common in patients with cirrhosis and is known to be a predictor of negative outcomes, but little is known about the effect of iron substitution in these individuals. In our cohort, increase of haemoglobin levels improved transplant-free survival of patients with cirrhosis. The increase of haemoglobin levels was mainly induced by iron supplementation and was even stronger in the case of concomitant use of iron and rifaximin. Clinical trial registration UME-ID-10042.

Abstract
Iron deficiency (ID) is a common comorbidity in heart failure (HF). In these patients, intravenous iron administration can improve clinical outcomes and quality of life (QoL). However, data on ID are lacking in patients who have transitioned toward left ventricular assist device (LVAD) or heart transplantation (HTx). All patients who underwent LVAD (n = 84) surgery or HTx (n = 67) at our center between 2012 and 2019, aged ≥18 years with a follow-up of ≥3 months, were included. Retrospectively, the prevalence of ID up to 1 year preoperatively, and up to February 2020 postoperatively, as well as all iron administrations were assessed during this period. Iron status was assessed in 61% and 51% of the LVAD and HTx patients preoperatively, and 81% and 84%, respectively, postoperatively. Of these patients, 53% and 71% of the LVAD and HTx patients preoperatively were diagnosed with ID preoperatively, and 71% and 77%, respectively, postoperatively. ID was more frequently diagnosed >3 months postoperatively. Sixty-three percent of the LVAD (mostly intravenous) and 63% of the HTx patients (mostly oral) received iron administration. ID is highly prevalent pre- and post-LVAD and HTx. It is plausible that substitution can have similar QoL gains as in regular HF patients.

Abstract
OBJECTIVES Corticosteroid is first-line therapy in immune thrombocytopenia. However, nearly 30% of patients appear in steroid-resistance. Our research analyses the relevant indicators of patients and develops a risk prediction model to predict the poor response to steroid-therapy in ITP patients. METHODS We collected data from 111 ITP patients admitted to Xiamen University Zhongshan Hospital from 2013 to 2019 as the training cohort and 65 ITP patients during 2019-2020 as the external validation cohort. Screening significant factors(P < 0.05) in univariate analysis, and further identified to be independent variables in multivariable logistic regression analysis. Incorporated the significant risk factors in and presented them with a nomogram based on independent risk predictors. The nomogram was assessed by receiver operating characteristics curves and decision curve analysis. RESULTS We constructed a steroid-resistance prediction model based on the potential predictors including age, serum ferritin and expression of HBsAg. As a result, based on the area under the ROC curves, the training cohort (AUC: 0.718, 95% CI: 0.615-0.821) and the external validation cohort (AUC:0.799,95%CI:0.692-0.905), which displayed good discrimination. The decision curve showed that predicting the steroid-refractory risk in ITP patients using this nomogram with a range of the threshold probability between >16% and <70%. The nomogram appears good performance in predicting steroid-refractory ITP patients. CONCLUSION Prediction model shows that elder patients with a high level of ferritin and positive expression of HBsAg may appear a high possibility of steroid-resistance. For these patients, TPO-RAs can be considered to help patients to get better treatment effects and develop a better health-related quality of life.

Abstract
BACKGROUND AND AIM Iron deficiency anemia (IDA)is the leading cause of anemia worldwide. Data on prevalence and clinical impact of anemia in cirrhosis are scarce. Aim was to report on the following:(i) prevalence of anemia and IDA in cirrhosis and (ii) its possible impact on clinical outcomes. METHODS Consecutive cirrhotic patients from a prospective registry study were included. Anemia was defined as hemoglobin concentration ≤ 12 g/dL. IDA was defined as Hb ≤ 12 g/dL + transferrin-saturation < 20%. Follow up for hepatic decompensation and mortality started with study inclusion and terminated in December 2017. A retrospective validation cohort of 1244 patients was used to validate our findings. RESULTS Two hundred forty-two patients with compensated (n = 53 [21.9%]) and decompensated (n = 189 [78.1%]) cirrhosis were included. Anemia was present in 128 patients (52.9%); of those, 63 (49.2%) had IDA. Prevalence of anemia increased with Child-Pugh Score (CPS; A: 26.5%, B: 59.2%, C: 69%; P < 0.001) and with decompensated cirrhosis(62.4% vs 18.8%, P < 0.001). Within anemic patients, a higher proportion of patients in CPS A/B vs C (73% vs 35%; P = 0.025) and in compensated cirrhosis (80% vs 46.6%; P = 0.043) were found with IDA. Model for End-Stage Liver Disease (MELD) scores were significantly lower in patients with IDA (14.4 vs 17.9 non-ID-anemia; P = 0.005). Similar results were found in the validation cohort: median MELD (16[8-28]non-IDA vs 12 [7-23] IDA; P < 0.001) and within anemic patients IDA was more common in patients with MELD <15 (58%) versus >15 (24%, P < 0.001). Anemia was associated with a significant risk for hepatic decompensation and/or mortality both in the validation (aSHR: 1.65, P = 0.008) and in the derivation cohort (aSHR: 2.11, P < 0.001) and an independent risk factor for hepatic decompensation and/or mortality in compensated patients (aHR: 4.91, P = 0.004). CONCLUSION Anemia is highly prevalent in cirrhosis. In compensated cirrhosis, CPS A/B, and low MELD, IDA seems to be the most likely reason for anemia. Furthermore, anemia is associated with a significant risk for hepatic decompensation or mortality during long-term follow up.

Abstract
Background Radiomics can be used to determine the prognosis of liver cancer, but it might vary among cancer types. This study aimed to explore the clinicopathological features, radiomics, and survival of patients with hepatocellular carcinoma (HCC), mass-type cholangiocarcinoma (MCC), and combined hepatocellular-cholangiocarcinoma (CHCC). Methods This was a retrospective cohort study of patients with primary liver cancer operated at the department of hepatobiliary surgery of the First Affiliated Hospital of Zhejiang University from 07/2013 to 11/2015. All patients underwent preoperative liver enhanced MRI scans and diffusion-weighted imaging (DWI). The radiomics characteristics of DWI and the enhanced equilibrium phase (EP) images were extracted. The mRMR (minimum redundancy maximum relevance) was applied to filter the parameters. Results There were 44 patients with MCC, 59 with HCC, and 33 with CHCC. Macrovascular invasion, tumor diameter, positive ferritin preoperatively, positive AFP preoperatively, positive CEA preoperatively, Correlation, Inverse Difference Moment, and Cluster Prominence in model A (DWI and clinicopathological parameters) were independently associated with overall survival (OS) (P<0.05). Lymphadenopathy, gender, positive ferritin preoperatively, positive AFP preoperatively, positive CEA preoperatively, Uniformity, and Cluster Prominence in model B (EP and clinicopathological parameters) were independently associated with OS (P<0.05). Macrovascular invasion, lymphadenopathy, gender, positive ferritin preoperatively, positive CEA preoperatively, Uniformity_EP, GLCMEnergy_DWI, and Cluster Prominence_EP in model C (image texture and clinicopathological parameters) were independently associated with OS (P<0.05). Those factors were used to construct three nomograms to predict OS. Conclusions Clinicopathological and radiomics features are independently associated with the OS of patients with primary liver cancer.

Abstract
BACKGROUND This systematic review was commissioned to identify new variables associated with transplant outcomes that are not currently collected by the Organ Procurement and Transplantation Network (OPTN). METHODS We identified 81 unique studies including 1 193 410 patients with median follow-up of 36 months posttransplant, reporting 108 unique risk factors. RESULTS Most risk factors (104) were recipient related; few (4) were donor related. Most risk factors were judged to be practical and feasible to routinely collect. Relative association measures were small to moderate for most risk factors (ranging between 1.0 and 2.0). The strongest relative association measure for a heart transplant outcome with a risk factor was 8.6 (recipient with the previous Fontan operation), for a kidney transplant 2.8 (sickle cell nephropathy as primary cause of end-stage renal disease), for a liver transplant 14.3 (recipient serum ferritin >500 µg/L), and for a lung transplant 6.3 (Burkholderia cepacia complex infection for 1 y or less). OPTN may consider some of these 108 variables for future collection to enhance transplant research and clinical care. CONCLUSIONS Evidence-based approaches can be used to determine variables collected in databases and registries. Several candidate variables have been identified for OPTN.

Abstract
Ethanol increases iron absorption. Therefore, increased amount of iron reaches the liver, and exerts pro-oxidant effects and stimulates ferritin synthesis and hepatic stellate cell activation, promoting fibrosis and inflammation. These mechanisms would theoretically support a role of ferritin as a marker of the transition to liver cirrhosis, and, consequently, as a prognostic factor, but there is controversy regarding its behavior in alcoholics. We analyzed among 238 severe alcoholics the prognostic value of iron, ferritin, transferrin, transferrin saturation index (TSI) and total iron binding capacity (TIBC), and the relationships of these variables with liver function, proinflammatory markers (C-reactive protein (CRP), interleukin (IL)-6, IL-8, and tumor necrosis factor α), and the presence of cirrhosis. Patients showed higher serum ferritin (Z = 2.50, p = 0.031) but lower transferrin (t(264) = 4.81, p < 0.001), TIBC (t(262) = 4.44, p < 0.001), and iron (Z = 3.19, p = 0.001) values compared with 32 age- and sex-matched controls. Ferritin was related to inflammatory cytokines such as IL-8 (ρ = 0.18, p = 0.012) and to IL-6 (ρ = 0.16, p = 0.016), but not to liver function. On the contrary, cirrhotics showed lower transferrin (t(234) = 4.77, p < 0.001) and TIBC (t(232) = 4.67, p < 0.001), but higher TSI (Z = 3.35, p < 0.001) than non-cirrhotics. Transferrin, TSI, and TIBC were related to liver function impairment (marked differences among the Child's groups regarding transferrin (KW (2) = 22.83, p < 0.001), TSI (KW (2) = 15.81, p < 0.001), and TIBC (KW (2) = 21.38, p < 0.001) but only weakly to inflammation (inverse relationships between IL-6 and total iron (ρ = - 0.16, p = 0.017), TIBC (ρ = - 0.20, p = 0.002), and transferrin (ρ = - 0.20, p = 0.003). In accordance, albumin, IL-6, alcohol quitting, and TSI, in this order, were independently related to mortality, but not ferritin or iron.

[PMID: 32390704 PMCID: PMC7201152 DOI: 10.3748/wjg.v26.i16.1938] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/30/2019] [Revised: 03/30/2020] [Accepted: 04/16/2020] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Liver transplantation (LT) is the best treatment for patients with liver cancer or end stage cirrhosis, but it is still associated with a significant mortality. Therefore identifying factors associated with mortality could help improve patient management. The impact of iron metabolism, which could be a relevant therapeutic target, yield discrepant results in this setting. Previous studies suggest that increased serum ferritin is associated with higher mortality. Surprisingly iron deficiency which is a well described risk factor in critically ill patients has not been considered.
AIM To assess the impact of pre-transplant iron metabolism parameters on post-transplant survival.
METHODS From 2001 to 2011, 553 patients who underwent LT with iron metabolism parameters available at LT evaluation were included. Data were prospectively recorded at the time of evaluation and at the time of LT regarding donor and recipient. Serum ferritin (SF) and transferrin saturation (TS) were studied as continuous and categorical variable. Cox regression analysis was used to determine mortality risks factors. Follow-up data were obtained from the local and national database regarding causes of death.
RESULTS At the end of a 95-mo median follow-up, 196 patients were dead, 38 of them because of infections. In multivariate analysis, overall mortality was significantly associated with TS > 75% [HR: 1.73 (1.14; 2.63)], SF < 100 µg/L [HR: 1.62 (1.12; 2.35)], hepatocellular carcinoma [HR: 1.58 (1.15; 2.26)], estimated glomerular filtration rate (CKD EPI Cystatin C) [HR: 0.99 (0.98; 0.99)], and packed red blood cell transfusion [HR: 1.05 (1.03; 1.08)]. Kaplan Meier curves show that patients with low SF (< 100 µg/L) or high SF (> 400 µg/L) have lower survival rates at 36 mo than patients with normal SF (P = 0.008 and P = 0.016 respectively). Patients with TS higher than 75% had higher mortality at 12 mo (91.4% ± 1.4% vs 84.6% ± 3.1%, P = 0.039). TS > 75% was significantly associated with infection related death [HR: 3.06 (1.13; 8.23)].
CONCLUSION Our results show that iron metabolism imbalance (either deficiency or overload) is associated with post-transplant overall and infectious mortality. Impact of iron supplementation or depletion should be assessed in prospective study.

Abstract
PURPOSE OF THE STUDY Hepatocellular carcinoma (HCC) has tripled in incidence over the past 20 years and now ranks as the third leading cause of mortality attributed to cancer. Underlying pathophysiology is sustained hepatic inflammation which results in hepatocellular dysplasia and thus an environment prone to HCC. Considering the essential role of inflammation in the pathogenesis of HCC, we evaluated the prognostic utility of ferritin-transferrin ratio (FTR) in HCC. METHODS We retrospectively reviewed the electronic medical records of patients with HCC (diagnosed on radiographic criteria and/or biopsy) from 2000 through 2015. We collected data regarding the patient demographics, laboratory investigations at the time of HCC diagnosis and prior to the initiation of treatment. Overall survival was calculated from the time of diagnosis, cases were censored at the date of last follow-up, if date of death was not known. Kaplan-Meier curves were estimated to evaluate the prognostic significance of FTR. Receiver operating characteristics (ROC) curve was plotted for FTR to predict mortality and identify cut-off value by optimized Youden's index. RESULTS Among the 176 patients identified by initial screening, 116 patients were eventually included for analysis. Overall median survival was 11.9 months. FTR, of note, was significantly lower in alive (6.9, p < 0.001). In univariate analysis, alfa-fetoprotein (AFP), aspartate aminotransferase (AST), serum ferritin (SF), transferrin (TFS), and FTR were significantly associated with mortality. On multivariate analysis for mortality, FTR, AFP, and epidemiologic factors predictive of mortality including male gender and advanced HCC were significant. CONCLUSION The ferritin-transferrin ratio (FTR), calculated at the time of HCC diagnosis could predict mortality in our cohort of patients. With an optimal cut-off of 7.7 for FTR were stratified into high- and low-risk groups. The hazard ratio between the two groups was 2.36 (p < 0.003). Future studies with longitudinal follow-up of FTR at intervals and important time points (e.g., perioperative) might provide more insights to its prognostic value.

Abstract
BACKGROUND Disturbances in iron regulation have been described in diverse chronic liver diseases other than hereditary haemochromatosis, and iron toxicity may worsen liver injury and outcome. AIMS To describe manifestations and consequences of iron dysregulation in chronic liver diseases apart from hereditary haemochromatosis and to encourage investigations that clarify pathogenic mechanisms, define risk thresholds for iron toxicity, and direct management METHODS: English abstracts were identified in PubMed by multiple search terms. Full length articles were selected for review, and secondary and tertiary bibliographies were developed. RESULTS Hyperferritinemia is present in 4%-65% of patients with non-alcoholic fatty liver disease, autoimmune hepatitis, chronic viral hepatitis, or alcoholic liver disease, and hepatic iron content is increased in 11%-52%. Heterozygosity for the C282Y mutation is present in 17%-48%, but this has not uniformly distinguished patients with adverse outcomes. An inappropriately low serum hepcidin level has characterised most chronic liver diseases with the exception of non-alcoholic fatty liver disease, and the finding has been associated mainly with suppression of transcriptional activity of the hepcidin gene. Iron overload has been associated with oxidative stress, advanced fibrosis and decreased survival, and promising therapies beyond phlebotomy and oral iron chelation have included hepcidin agonists. CONCLUSIONS Iron dysregulation is common in chronic liver diseases other than hereditary haemochromatosis, and has been associated with liver toxicity and poor prognosis. Further evaluation of iron overload as a co-morbid factor should identify the key pathogenic disturbances, establish the risk threshold for iron toxicity, and promote molecular interventions.

Abstract
Background & aims Hepatic iron accumulation can accelerate liver injury in patients with various chronic liver diseases and lead to hepatocarcinogenesis. We elucidated the impact of serum levels of ferritin on the prognosis of hepatocellular carcinoma (HCC) after radiofrequency ablation (RFA) in a large cohort. Methods We retrospectively analyzed 578 treatment-naïve HCC patients who underwent RFA. We divided our cohort into four groups by the quartile points of serum ferritin level: G1 (≤55 ng/mL, n = 148), G2 (56–130 ng/mL, n = 142), G3 (131–243 ng/mL, n = 144) and G4 (≥244 ng/mL, n = 144). We analyzed the recurrence and survival of patients using the Kaplan–Meier method. We also evaluated pathological iron deposition among patients with a solitary tumor smaller than 2 cm. Results The cumulative rates of overall recurrence and survival at 5 years were 81.6% and 66.3%, respectively. The serum levels of ferritin were correlated with pathological iron deposition. There were no significant differences in recurrence and survival rates according to serum levels of ferritin and pathological hepatic iron deposition. Conclusions Serum levels of ferritin do not affect the prognosis of HCC patients undergoing RFA.

Abstract
Patients with cirrhosis frequently present with high serum ferritin and low transferrin concentrations, reflecting impaired liver function and inflammation. Recent studies have shown that transferrin and its saturation with iron are Model for End-Stage Liver Disease-independent predictors of mortality in patients with acute-on-chronic liver failure or decompensated cirrhosis. The aim of this study was to evaluate the prognostic utility of serum iron parameters in relation to markers of liver function and immune activation. Clinical, demographic, and biochemical data were retrospectively analyzed from a cohort of 1255 consecutive patients with cirrhosis (age ≥ 18 years) who presented from August 1, 2004 until December 31, 2014 at the University Hospital of Innsbruck. Patients with malignancies at diagnosis including hepatocellular carcinoma were excluded. Survival analysis was carried out by Cox regression by using baseline laboratory parameters, and findings were validated in an independent patient cohort. During a median follow-up of 2.4 years, 193 deaths occurred and 254 patients underwent liver transplantation. In patients with transferrin < 180 mg/dL, 3-month, 1-year, and 5-year transplant-free survival estimates were significantly lower (91.7%, 79.0%, and 30.5%) when compared with the group of patients with transferrin ≥ 180 mg/dL (98.9%, 95.5%, and 68.0%, P < 0.001). Transferrin predicted transplant-free survival independently of Model for End-Stage Liver Disease-sodium (MELD-Na) and C-reactive protein (CRP) in multivariate regression analysis including all patients. When patients with alcoholic or nonalcoholic fatty liver disease were excluded, transferrin was in addition an albumin-independent predictor of transplant-free survival. In conclusion, the association of transferrin with transplant-free survival is independent of MELD-Na score and CRP. In patients without fatty liver disease, transferrin also predicts survival independently of albumin. Liver Transplantation 24 343-351 2018 AASLD.

Abstract
BACKGROUND & AIMS Serum ferritin and transferrin have been identified as prognostic markers in patients with chronic diseases. In this study, we investigated if these parameters can predict outcome in patients with acute liver failure. METHODS A total of 102 consecutive patients with acute liver failure were retrospectively analysed. The patients were grouped by outcome: spontaneous recovery vs liver transplantation and/or death or survival vs death. Routine laboratory parameters, transferrin and ferritin concentrations in serum, and anthropomorphic data collected on admission were analysed. RESULTS Non-spontaneously recovering patients had higher ferritin (12 252±25 791 vs 4434.4±9027.2 μg/L; P<.05) and lower transferrin levels (140.4±66.7 vs 206.9±65.8 mg/dL; P<.05) than spontaneously recovering patients. Similarly non-survivors exhibited higher serum ferritin and lower transferrin than non-transplanted survivors. Patients with severe hepatic inflammation (A3) had higher ferritin levels compared to patients with mild-moderate inflammation (A1-2) (5280±5094 vs 2361±2737 μg/L; P=.025). ROC analysis of single parameters was performed in non-transplanted patients, resulting in an area under the curve, sensitivity and specificity of 0.812%, 83.3%, and 77.1% for age, 0.871%, 84.1% and 75% for transferrin and 0.802%, 91.7% and 62.9% for ferritin. A model incorporating age, MELD and transferrin had the best predictive value with an area under the curve of 0.947, a sensitivity of 100% and corresponding specificity of 77.8%. CONCLUSIONS High ferritin and low transferrin levels are associated with worse outcome in patients with acute liver failure. A model incorporating age, MELD score and transferrin outperformed MELD score for 90-day overall survival of non-transplanted patients.

Hyperferritinemia and hypergammaglobulinemia predict the treatment response to standard therapy in autoimmune hepatitis. PLoS One 2017; 12:e0179074.

Abstract
Autoimmune hepatitis (AIH) is a chronic hepatitis with an increasing incidence. The majority of patients require life-long immunosuppression and incomplete treatment response is associated with a disease progression. An abnormal iron homeostasis or hyperferritinemia is associated with worse outcome in other chronic liver diseases and after liver transplantation. We assessed the capacity of baseline parameters including the iron status to predict the treatment response upon standard therapy in 109 patients with untreated AIH type 1 (AIH-1) in a retrospective single center study. Thereby, a hyperferritinemia (> 2.09 times upper limit of normal; Odds ratio (OR) = 8.82; 95% confidence interval (CI): 2.25–34.52) and lower immunoglobulins (<1.89 times upper limit of normal; OR = 6.78; CI: 1.87–24.59) at baseline were independently associated with the achievement of complete biochemical remission upon standard therapy. The predictive value increased when both variables were combined to a single treatment response score, when the cohort was randomly split into a training (area under the curve (AUC) = 0.749; CI 0.635–0.863) and internal validation cohort (AUC = 0.741; CI 0.558–0.924). Patients with a low treatment response score (<1) had significantly higher cumulative remission rates in the training (p<0.001) and the validation cohort (p = 0.024). The baseline hyperferritinemia was accompanied by a high serum iron, elevated transferrin saturations and mild hepatic iron depositions in the majority of patients. However, the abnormal iron status was quickly reversible under therapy. Mechanistically, the iron parameters were not stringently related to a hepatocellular damage. Ferritin rather seems deregulated from the master regulator hepcidin, which was down regulated, potentially mediated by the elevated hepatocyte growth factor. In conclusion, baseline levels of serum ferritin and immunoglobulins, which are part of the diagnostic work-up of AIH, can be used to predict the treatment response upon standard therapy in AIH-1, although confirmation from larger multicenter studies is pending.

Abstract
BACKGROUND & AIMS Iron represents an essential, but potentially harmful micronutrient, whose regulation has been associated with poor outcome in liver disease. Its homeostasis is tightly linked to oxidative stress, bacterial infections and systemic inflammation. To study the prognostic short-term significance of iron parameters in a cohort study of patients with decompensation of cirrhosis at risk of acute-on-chronic liver failure (ACLF). METHODS Ferritin, transferrin, iron, transferrin saturation (TSAT) and hepcidin were determined in sera from 292 German patients hospitalized for decompensation of cirrhosis with ascites, of which 78 (27%) had ACLF. Short-term mortality was prospectively assessed 30 and 90 days after inclusion. RESULTS Transferrin concentrations were significantly lower, whereas ferritin and TSAT were higher in patients with ACLF compared to patients without ACLF (P≤.006). Transferrin, TSAT and ferritin differentially correlated with the severity of organ failure, active alcoholism and surrogates of systemic inflammation and macrophage activation. As compared with survivors, 30-day non-survivors displayed lower serum transferrin (P=.0003) and higher TSAT (P=.003), whereas 90-day non-survivors presented with higher ferritin (P=.03) and lower transferrin (P=.02). Lower transferrin (continuous or dichotomized at 87 mg/dL) and consecutively higher TSAT (continuous or dichotomized >41%) indicated increased mortality within 30 days and remained significant after adjustment for organ failure and inflammation in multivariate regression models and across subgroups of patients. CONCLUSION Among the investigated indicators of iron metabolism, serum transferrin concentration was the best indicator of organ failure and an independent predictor of short-term mortality at 30 days.

Abstract
Introduction: Nonalcoholic fatty liver disease (NAFLD) is raising prevalence among children, and adolescence population in developed and developing countries as a major public health concern. The present study aims to determine the relationship between serum ferritin level and transient elastography findings in patients suffering from NAFLD. Materials and Methods: The demographic and biochemical profile of included individuals such as body mass index, age, level of serum transaminases, fasting blood sugar, lipid profile, and serum ferritin level were determined and a transient elastography was performed for all of them. Results: The mean serum ferritin level among men with mild and advanced liver stiffness was 154 ± 97 and 244 ± 214, respectively (P < 0.001), which showed a meaningful relationship. These figures among female patients with mild and advanced liver stiffness included 79 ± 91 and 161 ± 103, respectively (P = 0.003) and again revealed a significant relationship. The cutoff values of ferritin with 90% accuracy for differentiation of mild from advanced liver stiffness among male and female patients were determined as 255 ng/ml and 135 ng/ml, respectively. These cutoff values for ruling out of advanced liver stiffness with 90% accuracy among both sexes were 72.5 ng/ml and 65.5 ng/ml, respectively. Conclusion: The finding of this study revealed a significant relationship between serum ferritin level and liver stiffness among NAFLD patients, and if these results repeated in further investigations, it could be advisable to measure serum ferritin level for predicting possibility of advanced liver fibrosis.

High serum ferritin is associated with worse outcome of patients with decompensated cirrhosis. Ann Gastroenterol 2016; 30:217-224. [PMID: 28243043 PMCID: PMC5320035 DOI: 10.20524/aog.2016.0112] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/11/2016] [Accepted: 11/08/2016] [Indexed: 12/16/2022] Open
Abstract
BACKGROUND Studies in patients with decompensated cirrhosis showed a correlation between serum ferritin levels and patients' prognosis. Besides, red blood cell distribution width (RDW) and mean platelet volume (MPV) have been associated with the severity of hepatic function. The aim of this study was to evaluate the prognostic impact of serum ferritin and RDW/MPV in the outcome [survival, death, or liver transplantation (LT)] of patients with stable decompensated cirrhosis. METHODS Consecutive adult patients with stable decompensated cirrhosis admitted to our department between September 2010 and February 2016 were included. Serum ferritin, RDW and MPV were recorded in every patient. They were followed up and their outcome (alive, death, or LT) was evaluated. RESULTS 192 consecutive patients with stable decompensated cirrhosis (142 men, age 54.2±12 years); at the end of follow up [12 (range: 1-64) months] 62 patients remained alive and 130 died or underwent LT. In multivariate analysis, serum ferritin (HR 1.001, 95%CI 1.00-1.002, P=0.005) and GFR (HR 0.96, 95%CI 0.92-0.99, P=0.035) were the only independent factors significantly associated with the outcome. Ferritin had low discriminative ability (AUC: 0.61) to the outcome yielding a sensitivity and specificity of 85.3% and 44.2%, respectively, at the best cut-off point (>55 ng/mL), while patients with ferritin >55 ng/mL (n=145) had a worse outcome compared to those with ferritin ≤55 ng/mL (n=47) (log rank P=0.001). RDW and MPV were not associated with the outcome. CONCLUSION High serum ferritin, but not RDW/MPV, is associated with worse outcome in patients with established decompensated cirrhosis. However, further studies are needed to elucidate better this issue.

Abstract
BACKGROUND & AIMS High levels of ferritin in patients with non-alcoholic fatty liver disease (NAFLD) are associated with significant fibrosis and higher NAFLD activity score (NAS). It is unclear if this association has an impact on mortality. We investigated if high levels of ferritin, with or without iron overload, were associated with an increased mortality in NAFLD. METHODS We included 222 patients between 1979 and 2009 with biopsy-proven NAFLD and available serum ferritin concentrations. The cohort was divided into 'high' (n = 89) and 'normal' (n = 133) ferritin values, using a cut-point of 350 μg/L in males, and 150 μg/L in females, and stratified upon iron overload status. Data on mortality were obtained from a national, population-based register. Poisson regression was used to estimate hazard ratios for mortality. The estimates were adjusted for age at biopsy, sex, smoking, BMI, diabetes, hypertension, cardiovascular disease and fibrosis stage at the time of biopsy. RESULTS The median follow-up time was 15.6 years (range: 0.5-34.2). Patients with high ferritin had more advanced fibrosis and higher NAS than patients with normal ferritin (P < 0.05). Fifteen years after diagnosis, and after adjusting for confounders, the high-ferritin group showed an increasingly higher mortality that was statistically significant (Hazard ratio = 1.10 per year, 95% Confidence interval 1.01-1.21, P < 0.05). There was no difference in mortality between patients with different iron overload patterns. CONCLUSIONS High levels of ferritin are associated with a long-term increased risk of death.

Abstract
AIM To elucidate the impact of the serum ferritin level, a surrogate indicator of hepatic iron accumulation, on hepatocarcinogenesis in chronic hepatitis C patients. METHODS Serum ferritin was measured in 487 chronic hepatitis C patients without history of hepatocellular carcinoma (HCC) after excluding patients in phlebotomy, those with overt chronic gastrointestinal bleeding and those who achieved sustained virological response before enrollment. Patients were divided into four groups (G1-G4) by quartile points of serum ferritin, with sexes separated. RESULTS The serum ferritin level was positively correlated with total bilirubin, aspartate aminotransferase, alanine aminotransferase (ALT), γ-glutamyltransferase, hemoglobin and AFP, and inversely correlated with prothrombin activity in both sexes. A significant difference in HCC incidence was observed only in male patients; the incidence was higher in G1 (≤80 ng/mL, n = 54) and G4 (≥323 ng/mL, n = 54) compared with that of G2 (81-160 ng/mL, n = 54) and G3 (161-322 ng/mL, n = 52). The spline curve indicating the relationship between the hazard ratio and serum ferritin level took the form of a J-shape for male patients. In multivariate analysis, G1 and G4 showed higher incidence of HCC among men with a hazard ratio of 2.19 (95% confidence interval, 1.02-4.70; P = 0.045) compared with G2 and G3, together with older age, lower serum albumin and ALT above the normal upper limit. CONCLUSION The serum ferritin level is an independent risk factor for HCC development in male patients with chronic hepatitis C when the level is extremely high or low.

Abstract
Donor organs for transplantations are a scarce commodity; therefore, allocation systems are needed that guarantee an ethically acceptable distribution to patients on the waiting list (equal treatment and fairness) but also take the probability of survival of the transplant in each recipient into consideration. In this article the allocation systems for lung, liver, kidney and pancreas transplants are presented.For lung transplantations an allocation system based on the lung allocation score (LAS) is currently used. The LAS predicts the probability of survival on the waiting list and the survival rate following transplantation. Organs with a limited range of utilization are distributed in a so-called mini-match procedure.For post-mortem kidney and pancreas transplantations a relatively complex but transparent allocation system has been created in which patients are subdivided into groups, each of which has its own allocation rules. The allocation is principally carried out according to criteria of fairness of distribution and according to the prospects of success. The probability of a mismatch also plays a role. The urgency is important for children and for patients who do not have the possibility of dialysis. Combined pancreas and kidney transplantations have priority over kidney transplantations alone.The criterion for the urgency of liver transplantation in Germany is currently the model for end-stage liver disease (MELD), which aims to reduce the waiting list mortality and to prioritize transplantations for those most in need. Because the system insufficiently describes the priority of transplantation for patients with tumors or genetic liver diseases, there is an additional set of rules for so-called standard exceptions.

Abstract
BACKGROUND Decompensated liver cirrhosis is an important cause of mortality worldwide. Various modifiable and non-modifiable factors are involved in the pathogenesis of cirrhosis and its complications. This study was aimed to evaluate the association of iron overload and disease severity in patients of liver cirrhosis and its association with HFE gene mutation. METHODS Forty-nine patients with decompensated liver cirrhosis were recruited. Clinical and laboratory parameters were compared in patients with and without iron overload. C282Y and H63D gene mutation analysis was performed in all patients with iron overload. RESULTS Iron overload was found in 20 (40.82%) patients. A significant positive correlation of transferrin saturation with Child-Turcotte-Pugh (CTP) score (r = 0.705, p < 0.001) and model for end-stage liver disease (MELD) score (r = 0.668, p < 0.001) was found. Transferrin saturation was also independently associated with high CTP and MELD score on multivariate analysis. Mortality over 3 months was significantly more common in iron-overloaded patients (p = 0.028). C282Y homozygosity or C282Y/H63D compound heterozygosity was not found in any of the patients with iron overload. CONCLUSION Iron overload was significantly associated with disease severity and reduced survival in patients of decompensated liver cirrhosis.

Abstract
The serum ferritin (SF) concentration is a widely available and objective laboratory parameter. SF is also widely recognized as an acute-phase reactant. The purpose of the present study was to identify the chronological changes in the recipient's SF concentration during liver transplantation (LT) and to clarify factors having an effect on the recipient's intraoperative SF level. In addition, the study retrospectively evaluated the usefulness of measuring SF during LT. Ninety-eight pediatric recipients were retrospectively analyzed. The data were analyzed and compared according to the SF level in the recipient. Patients were classified into 2 groups based on the intraoperative peak SF levels of ≤ 1000 ng/mL (low-SF group) or >1000 ng/mL (high-SF group). The SF value increased dramatically after reperfusion and fell to normal levels within the early postoperative period. The warm ischemia time (WIT) was significantly longer in the high-SF group (47.0 versus 58.5 minutes; P = 0.003). In addition, a significant positive correlation was observed between the peak SF value and WIT (r = 0.35; P < 0.001). There were significant positive correlations between the peak SF value and the donors' preoperative laboratory data, including transaminases, cholinesterase, hemoglobin, transferrin saturation, and SF, of which SF showed the strongest positive correlation (r = 0.74; P < 0.001). The multivariate analysis revealed that WIT and donor's SF level were a significant risk factor for high SF level in the recipient (P = 0.007 and 0.02, respectively). In conclusion, the SF measurement can suggest the degree of ischemia/reperfusion injury (IRI). A high SF level in the donor is associated with the risk of further acute reactions, such as IRI, in the recipient.

Abstract
BACKGROUND/AIMS Iron overload is an increasingly recognized phenomenon in nonhemochromatosis cirrhosis. To evaluate the relationship between iron overload and liver insufficiency and portal hypertension. PATIENTS AND METHODS Cirrhotics with hepatic hemodynamic and ferritin measurement (within 30 d) were included. Exclusion criteria were malignancy (except hepatocellular carcinoma Milan-in), severe chronic obstructive pulmonary disease, acute events in the previous 2 weeks, immunosuppression, transjugular intrahepatic portosystemic shunt or portal vein thrombosis, and end-stage renal disease. Patients were followed-up until death or liver transplant. Univariate and multivariate analysis were used. RESULTS Fifty-one patients were included (male 61%; median age 57 y; interquartile range, 47 to 66 y); Child-Pugh A 11/B 25/C 15). A positive correlation was observed between ferritin and markers of inflammation (C-reactive protein: r=0.273, P=0.06 and aspartate aminotransferase: r=0.302, P=0.035). No correlation between ferritin and hepatic venous pressure gradient was seen. Negative correlations were observed between ferritin and circulatory dysfunction (mean arterial pressure: r=-0.360, P=0.014 and serum sodium: r=-0.419, P=0.002). In contrast, associations to markers of liver failure such as international normalized ratio (r=0.333, P=0.005), bilirubin (r=0.378, P=0.007), albumin (r=-0.265, P=0.082), model for end-stage liver disease (r=0.293, P=0.041), and Child-Pugh score (r=0.392, P=0.009) were observed. No differences in survival according to ferritin was detected. CONCLUSIONS In patients with cirrhosis, serum ferritin levels are associated with markers of liver insufficiency, inflammation, and circulatory dysfunction but not portal hypertension.

Abstract
Obesity is a rapidly growing health problem and is paralleled by a multitude of comorbidities, including nonalcoholic fatty liver disease (NAFLD). NAFLD has become the most common chronic liver disease in both adults and children. The current understanding of NAFLD is still fragmentary. While simple steatosis is characterized by the interplay between excessive free fatty acid accumulation and hepatic insulin resistance, the progression to NASH has been related to oxidative stress and a proinflammatory state with dysbalanced adipokine, cytokine levels, and endotoxin-mediated immune response. In addition, oxidative stress has been suggested to play a central role for the sequelae leading to NASH. Trace elements are critical in regulatory, immunologic, and antioxidant functions resulting in protection against inflammation and peroxidation and consequently against the known comorbidities of obesity. Disruptions of the metal detoxification processes located in the liver are plausibly related to NAFLD development via oxidative stress. Perturbations of iron and copper (Cu) homeostasis have been shown to contribute to the pathogenesis of NAFLD. This review presents current data from pediatric studies. In addition, data from adult studies are summarized where clinical relevance may be extrapolated to pediatric obesity and NAFLD.

Abstract
AIM The aims of the study were to determine the levels of serum ferritin which predict fibrosis in Indian patients with nonalcoholic fatty liver disease (NAFLD) and to establish correlation between Fibroscan values and serum ferritin levels. METHODS The clinical, biochemical, radiologic, and histological findings of consecutive adult NAFLD patients accessed at a tertiary care center over a 3-year period were analyzed. Those with concurrent liver diseases were excluded. Fifty-five of 250 NAFLD patients with fatty liver on ultrasound and raised enzymes (>40 IU/L) underwent liver biopsy. Patients were stratified into two groups based on their histological stage steatosis (with or without inflammation) but no fibrosis and nonalcoholic steatohepatitis (NASH) with fibrosis/cirrhosis. Serum ferritin levels were measured at the same time as getting liver biopsy. Fibroscan was carried out in each of these patients. These were compared with 50 age- and sex-matched controls with normal ultrasound, liver enzymes, and no history of alcohol. Student's t test was used as the test for significance. RESULTS Fifty-five NAFLD patients diagnosed on ultrasound and with raised enzymes underwent biopsy. Steatosis (with or without inflammation, but no fibrosis/ballooning) was seen in 35 patients, fibrosis/ballooning in 14 patients, and cirrhosis in 6 patients. Mean ferritin levels in groups with nonalcoholic fatty liver (NAFL) and nonalcoholic steatohepatitis (NASH) were 39.4 and 72.7 ng/mL, respectively (p < 0.001). The mean ferritin levels in NAFLD and controls were 51.2 and 35.2 ng/mL, respectively (p < 0.05). The area under the curve (AUC) of serum ferritin at value 48.0 ng/mL was 0.779. The coefficient of correlation between Fibroscan and serum ferritin levels was 0.9864 while that with alanine transaminase and aspartate aminotransferase was 0.69. Serum ferritin at the cutoff of 48 ng/mL differentiated significantly patients with fibrosis and higher Fibroscan levels. CONCLUSION Serum ferritin was low in Indian individuals, and levels even within apparently normal range indicated fibrosis and cirrhosis. A cutoff level of 48.0 IU/mL distinguished fibrosis in NAFLD. Fibroscan correlated well with serum ferritin levels.

Dysregulated iron homeostasis is strongly associated with multiorgan failure and early mortality in acute-on-chronic liver failure. Hepatology 2015; 61:1306-20. [PMID: 25475192 DOI: 10.1002/hep.27636] [Citation(s) in RCA: 57] [Impact Index Per Article: 6.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/22/2014] [Revised: 10/22/2014] [Accepted: 11/20/2014] [Indexed: 12/11/2022]
Abstract
UNLABELLED Acute-on-chronic liver failure (ACLF) is an ailment with high incidence of multiorgan failure (MOF) and consequent mortality. Dysregulated iron homeostasis and macrophage dysfunction are linked to increased incidence of MOF. We investigated whether a panel of circulating iron-regulating proteins are associated with development of MOF and can predict 15- or 30-day mortality in ACLF patients. One hundred twenty patients with ACLF, 20 patients with compensated cirrhosis, and 20 healthy controls were studied. Relative protein expression profiling was performed in the derivative cohort and confirmed in the validation cohort. A panel of iron regulators and indices were determined. Multiparametric flow cytometry for quantitation of labile iron pool (LIP) was performed. Validation studies confirmed lower serum transferrin (Tf) and ceruloplasmin levels in ACLF and ACLF-MOF, compared to patients with cirrhosis and controls (P < 0.01). Serum iron and ferritin levels were markedly elevated (P < 0.001; P < 0.05) and hepcidin levels were lower (P < 0.001) in ACLF patients with MOF than those without and other groups (P < 0.001). Percentage Tf saturation (%SAT) was higher in ACLF-MOF (39.2%; P < 0.001) and correlated with poor outcome (hazard ratio: 6.970; P < 0.01). Intracellular LIP indices were significantly elevated in the subsets of circulating macrophages in ACLF-MOF, compared to other groups (P < 0.01). Whereas expression of iron-regulatory genes was markedly down-regulated, genes related to endoplasmic reticulum stress, apoptosis, and inflammation were up-regulated in ACLF patients, compared to patients with cirrhosis. Severe dysregulation of autophagy mechanisms was also observed in the former. CONCLUSIONS Iron metabolism and transport are severely deranged in ACLF patients and more so in those with MOF. %SAT, circulating hepcidin, and LIP in macrophages correlate with disease severity and %SAT could be used for early prognostication in ACLF patients.

Abstract
Elevated iron stores as indicated by hyperferritinemia with normal or mildly elevated transferrin saturation and mostly mild hepatic iron deposition are a characteristic finding in subjects with non-alcoholic fatty liver disease (NAFLD). Excess iron is observed in approximately one third of NAFLD patients and is commonly referred to as the “dysmetabolic iron overload syndrome”. Clinical evidence suggests that elevated body iron stores aggravate the clinical course of NAFLD with regard to liver-related and extrahepatic disease complications which relates to the fact that excess iron catalyses the formation of toxic hydroxyl-radicals subsequently resulting in cellular damage. Iron removal improves insulin sensitivity, delays the onset of type 2 diabetes mellitus, improves pathologic liver function tests and likewise ameliorates NAFLD histology. Several mechanisms contribute to pathologic iron accumulation in NAFLD. These include impaired iron export from hepatocytes and mesenchymal Kupffer cells as a consequence of imbalances in the concentrations of iron regulatory factors, such as hepcidin, cytokines, copper or other dietary factors. This review summarizes the knowledge about iron homeostasis in NAFLD and the rationale for its therapeutic implications.

Abstract
Recipient's iron status is an important determinant of clinical outcome in transplantation medicine. This review addresses iron metabolism in solid organ transplantation, where the role of iron as a mediator of ischemia-reperfusion injury, as an immune-modulatory element, and as a determinant of organ and graft function is discussed. Although iron chelators reduce ischemia-reperfusion injury in cell and animal models, these benefits have not yet been implemented into clinical practice. Iron deficiency and iron overload are associated with reduced immune activation, whose molecular mechanisms are reviewed in detail. Furthermore, iron overload and hyperferritinemia are associated with poor prognosis in end-stage organ failure in patients awaiting kidney, or liver transplantation. This negative prognostic impact of iron overload appears to persist after transplantation, which highlights the need for optimizing iron management before and after solid organ transplantation. In contrast, iron deficiency and anemia are also associated with poor prognosis in patients with end-stage heart failure. Intravenous iron supplementation should be managed carefully because parenterally induced iron overload could persist after successful transplantation. In conclusion, current evidence shows that iron overload and iron deficiency are important risk factors before and after solid organ transplantation. Iron status should therefore be actively managed in patients on the waiting list and after transplantation.

Abstract
BACKGROUND & AIMS Serum ferritin is a known marker of hepatic necro-inflammation and has been studied to predict 1 year mortality and post-transplant survival in decompensated cirrhotics. However, there are no studies evaluating ferritin as a predictor of early mortality. We investigated whether serum ferritin levels could predict 15 day and 30 day mortality in patients with decompensated cirrhosis. METHODS 318 patients with decompensated cirrhosis were included. RESULTS Patients of decompensated cirrhosis [257 males, mean age of 51 [±13]years, were followed for a median of 31 days. Serum ferritin levels were significantly different between survivors and non-survivors [p<0.001] and showed significant correlation with MELD score [p<0.001], CTP score [p<0.001], leucocyte counts [TLC] [p<0.001], serum sodium [p<0.001], ACLF grades [p=0.005], spontaneous bacterial peritonitis [SBP] [p=0.02], hepatic encephalopathy [HE] [p<0.001] and hepatorenal syndrome [HRS] [p=0.012]. Serum ferritin, etiology, MELD, HE, CTP score, sodium, TLC, and ACLF grades were significant predictors of mortality on univariate analysis. Ferritin [p=0.04, HR 1.66 95% CI (1.02-2.73)] was a significant predictor of early mortality on multivariate analysis along with HE [p=0.006, HR 3.47 95% CI (2.13-8.41)] (Model 1), TLC [p=0.02, HR 1.81 95% CI (1.06-3.07)] (Model 2), ACLF grades [p=0.018, HR 2.013,95% CI (1.126-3.60)], and CTP score [p<0.0001, HR 1.36 95% CI (1.17-1.59)] (Model 3). CONCLUSION Serum ferritin levels correlate with severity of hepatic decompensation and are associated with early liver related death independent of the MELD score in hospitalized patients with decompensated cirrhosis. This could also have a potential therapeutic implication.

The association of pretransplant ferritin level with waiting list and post-transplant survival. Does ferritin actually predict outcome? Transpl Int 2014; 26:1070-9.

Abstract
Recent data suggest an association of serum ferritin (SF) with waiting list (WL) and postliver transplant (LT) outcomes. To assess the predictive capacity of SF on pre- and post-LT outcomes, and to identify whether recipient or donor liver siderosis is associated with post-LT survival; a retrospective analysis of 1079 patients assessed for first LT, 2000-2007 was performed. Iron deposition in the liver tissue was assessed using a semi-quantitative grading system. Median age was 54 (18-82) years and 67% were male. Seventeen per cent had hepatocellular carcinoma (HCC). Median Model for End-stage Liver Disease MELD score was 14 (6-40), ferritin was 174 μg/l (4-4597) with 36.5% had a SF ≥ μg/l. Age (OR = 1.028) and MELD score (OR = 1.158) were independently associated with WL mortality (P < 0.001), whilst SF was not (P = NS). Age (OR = 1.018), HCC (OR = 1.542) and cold ischemia time (CIT) ≥ 10 h (OR = 1.418) were independently associated with post-LT survival (P < 0.05). Explant siderosis grade <2 was seen in 376 (71.7%) patients. Patients with explant siderosis grade ≥ 2 had inferior 12-month post-LT survival (P = 0.030). Presence of graft siderosis (15.8% of patients) was not associated with survival. In conclusion, we found a limited role for SF as a prognostic indicator for pre- or post-transplant survival.

Abstract
BACKGROUND The worldwide incidence rates of hepatocellular carcinoma (HCC) vary widely. Some countries like India have a low incidence despite having a large burden of chronic hepatitis B (HBV) and C virus (HCV) infection. We hypothesized that long-term iron deficiency could attenuate the hepatic inflammation and lead to a lower incidence of HCC in India than expected. METHODS We evaluated the association of serum ferritin levels and HCC in Indian patients with HBV- or HCV-related chronic liver disease (CLD) using a case-control study design. We enrolled 141 patients with HCC (cases) and 240 patients having chronic HBV or HCV infection-related CLD (controls). Study participants were grouped on the basis of ferritin values into low-normal, high-normal, and high subgroups. RESULTS Mean ferritin values were higher in cases as compared to controls (425.8 vs. 135.6 ng/mL, p = 0.000). A significant dose-response effect for serum ferritin levels and HCC was seen with an odds ratio (95 % confidence interval) of 3.0 (1.6-5.9, p = 0.001) for subjects with high-normal ferritin levels and 8.2 (4.1-16.5, p = 0.000) for subjects with high ferritin levels in a multivariate model. Other significant independent risk factors in the multivariate model included older age, male gender, alcohol and tobacco use, elevated alanine aminotransferase, higher family income, and coffee drinking. CONCLUSION We found an independent association between serum ferritin levels and HCC in patients with CLD of viral etiology. Further prospective studies are needed to confirm the hypothesis that iron deficiency protects against HCC in CLD.

Abstract
The metabolic syndrome (MetS) affects iron homeostasis in a many-faceted fashion. On the one side, hyperferritinaemia with normal or mildly elevated transferrin saturation is observed in approximately one-third of patients with non-alcoholic fatty liver disease (NAFLD) or the MetS. This constellation has been named the 'dysmetabolic iron overload syndrome (DIOS)'. Current evidence suggests that elevated body iron stores exert a detrimental effect on the clinical course of obesity-related conditions and that iron removal improves insulin sensitivity and delays the onset of T2DM. On the other side, iron deficiency is a frequent finding in more progressed stages of obesity. The mechanisms underlying the DIOS and obesity-related iron deficiency appear strikingly similar as elevated hepcidin concentrations, low expression of duodenal ferroportin (FPN) and impaired iron absorption are found in both conditions. This review summarizes the current knowledge about the dysregulation of iron homeostasis in the MetS and particularly in its hepatic manifestation NAFLD.

Abstract
BACKGROUND/AIMS Liver biopsy is considered a gold standard for fibrosis staging, but it has a high risk of morbidity. Therefore, there is an interest in developing noninvasive markers for the prediction of liver fibrosis stages. METHODS Hyaluronic acid, ferritin, N-acetyl-β-D-glucosaminidase, β-glucuronidase, glucosamine, aspartate transaminase, and alanine transaminase were assayed in 210 individuals with chronic hepatitis C infection. Statistical analysis was carried out by logistic regression and receiver-operating characteristic curves. RESULTS The best linear combination of only significant blood markers was used for the determination of the fibrosis discriminant score; score=[1.64 (numerical constant)-0.002×hyaluronic acid (pg/l)-2.68×β-glucuronidase (µmol/ml/min)-0.026×glucosamine (µg/dl)-0.001×ferritin-0.033 (ng/ml)×aspartate transaminase/alanine transaminase]. The selected fibrosis discriminant score function correctly classified 81% of patients with severe liver fibrosis at a discriminant cut-off score=0.55 (i.e. less than 0.55 indicated mild liver fibrosis and greater than 0.55 indicated severe liver fibrosis), with a sensitivity of 100% and a specificity of 73%. CONCLUSION A simple fibrosis index can be useful to select hepatitis C virus-infected patients with a very low risk of significant fibrosis in whom the protocol of liver biopsies may be avoided.

Abstract
BACKGROUND Serum hepcidin concentration is potentially affected by inflammation and iron stores in chronic liver disease (CLD), but little is known about the relationship between hepcidin and the degree of hepatic fibrosis. We investigated the potential role of serum hepcidin as a biomarker of advanced liver disease. METHODS Serum hepcidin was measured in 332 adults with CLD of varying aetiologies, 45 healthy and 50 non-liver disease patient controls. Liver biopsy data were available for 228 CLD subjects. RESULTS Hepcidin was decreased in CLD patients compared with non-liver disease patient controls (P < 0.0001) but not healthy controls, and was lowest in those with cirrhosis (P < 0.0001). Serum hepcidin correlated with hepatic hepcidin mRNA expression in 91 biopsy samples available for genetic analysis (r = 0.68, P < 0.0001). Hepcidin also correlated positively with serum ferritin concentration, transferrin saturation, ALT, serum albumin and haemoglobin, but negatively with serum bilirubin. The hepcidin:ferritin ratio was significantly lower in CLD subjects compared with healthy and disease controls, and decreased with each increase in the stage of fibrosis and siderosis. The hepcidin:ferritin ratio was associated with progressive fibrosis on linear regression, and a value of less than 0.1 was independently associated with cirrhosis on logistic regression analyses (OR 5.54, P < 0.001). Receiver operating characteristic analysis showed the hepcidin:ferritin ratio was able to distinguish between F0 and F4 stages of fibrosis (area under receiver operating characteristic curve = 0.86). CONCLUSIONS The hepcidin:ferritin ratio is reduced in relation to increasing fibrosis in CLD and the use of this ratio may have potential future diagnostic implications as a marker of cirrhosis.

Abstract
UNLABELLED Serum ferritin (SF) levels are commonly elevated in patients with nonalcoholic fatty liver disease (NAFLD) because of systemic inflammation, increased iron stores, or both. The aim of this study was to examine the relationship between elevated SF and NAFLD severity. Demographic, clinical, histologic, laboratory, and anthropometric data were analyzed in 628 adult patients with NAFLD (age, ≥ 18 years) with biopsy-proven NAFLD and an SF measurement within 6 months of their liver biopsy. A threshold SF >1.5 × upper limit of normal (ULN) (i.e., >300 ng/mL in women and >450 ng/mL in men) was significantly associated with male sex, elevated serum alanine aminotransferase, aspartate aminotransferase, iron, transferrin-iron saturation, iron stain grade, and decreased platelets (P < 0.01). Histologic features of NAFLD were more severe among patients with SF >1.5 × ULN, including steatosis, fibrosis, hepatocellular ballooning, and diagnosis of NASH (P < 0.026). On multiple regression analysis, SF >1.5 × ULN was independently associated with advanced hepatic fibrosis (odds ratio [OR], 1.66; 95% confidence interval [CI], 1.05-2.62; P = 0.028) and increased NAFLD Activity Score (NAS) (OR, 1.99; 95% CI, 1.06-3.75; P = 0.033). CONCLUSIONS A SF >1.5 × ULN is associated with hepatic iron deposition, a diagnosis of NASH, and worsened histologic activity and is an independent predictor of advanced hepatic fibrosis among patients with NAFLD. Furthermore, elevated SF is independently associated with higher NAS, even among patients without hepatic iron deposition. We conclude that SF is useful to identify NAFLD patients at risk for NASH and advanced fibrosis.
