RESUMEN
Pre-treatment host and viral factors may affect serum ferritin levels in patients with hepatitis C virus (HCV) infection. We delineated pre-treatment factors associated with hyperferritinemia in these patients. 1682 eligible patients underwent pre-treatment assessment for serum ferritin and various host/viral factors. Univariate and multivariate logistic regression analyses were conducted to evaluate factors associated with hyperferritinemia. Multivariate logistic regression analyses revealed that age > 50 years (adjusted odds ratio [OR]: 1.38 (95% confidence interval [CI] 1.09-1.74), p = 0.008), fibrosis stage ≥ F3 (adjusted OR: 1.36 (95% CI 1.04-1.77), p = 0.02), fibrosis index based on four parameters (FIB-4) > 3.25 (adjusted OR: 1.46 (95% CI 1.11-1.92), p = 0.01), presence of metabolic dysfunction-associated steatotic liver disease (MASLD) (adjusted OR: 1.43 (95% CI 1.21-1.76), p = 0.001), and alanine transaminase (ALT) > 2 folds upper limit of normal (ULN) (adjusted OR: 2.87 (95% CI 2.20-3.75), p < 0.001) were associated hyperferritinemia. The log10 value of HBV or HCV viral load was not associated with the log10 value of ferritin level (Spearman's rank correlation coefficient: - 0.025, p = 0.81 and 0.002, p = 0.92). In conclusion, host factors, rather than viral factors, are associated with hyperferritinemia in patients with HCV.

OBJECTIVE: The aim of this study was to assess the role of elevated serum ferritin levels in the onset, pathological progression and prognosis of nonalcoholic fatty liver disease. Nonalcoholic fatty liver disease has been rapidly increasing worldwide. Despite extensive research on the pathogenesis of nonalcoholic fatty liver disease, a lack of sufficient clinical research on the relationship between nonalcoholic fatty liver disease and serum ferritin levels remains. METHODS: We analysed 968 patients with type 2 diabetes mellitus who underwent liver ultrasound examination and had their serum ferritin levels measured. The presence of nonalcoholic fatty liver disease and advanced liver fibrosis was determined through abdominal ultrasound examination and the nonalcoholic fatty liver disease fibrosis score. RESULTS: Compared to that in the non-nonalcoholic fatty liver disease group, the presence of hyperferritinemia was significantly more common in the nonalcoholic fatty liver disease group (83.3 vs. 56.3%, p=0.005). When patients with nonalcoholic fatty liver disease were stratified by the nonalcoholic fatty liver disease fibrosis score, those with advanced liver fibrosis exhibited a higher prevalence of hyperferritinemia (56.3, 78.9, and 88.9% for none, simple steatosis, and advanced fibrosis, respectively; p for trend=0.002). In multivariate logistic regression, liver fibrosis was independently associated with hyperferritinemia (odds ratio [OR] 1.45; 95% confidence interval [CI] 1.18-2.02; p=0.014), and this association remained significant in male patients after adjusting for other risk factors (OR 2.66; 95% CI 1.43-5.48; p=0.026). CONCLUSION: Identifying nonalcoholic fatty liver disease patients at a risk of developing nonalcoholic steatohepatitis and advanced fibrosis is crucial for implementing timely interventions and improving patient outcomes. This study highlights the potential utility of serum ferritin levels as a serum biomarker for identifying nonalcoholic steatohepatitis patients and those at a risk of late-stage fibrosis, particularly in male patients with nonalcoholic fatty liver disease.

BACKGROUND & AIMS: Hyperferritinemia reflects iron accumulation in the body and has been associated with metabolic disturbances and alcohol use, and is also a common finding in individuals diagnosed with liver disease. The major genetic regulator of iron metabolism is the HFE gene. METHODS: The aim of this this study was to investigate the association between serum ferritin and liver fibrosis using the enhanced liver fibrosis (ELF) test, and the association between ferritin and liver-related outcomes in a Finnish population-based cohort of 6194 individuals (45% male, mean [± standard deviation] age, 52.9 ± 14.9 years; body mass index 26.9 ± 4.7 kg/m2). The effects of HFE variants on these associations were also evaluated. RESULTS: Serum ferritin levels were significantly associated with liver fibrosis, as estimated by enhanced liver fibrosis (ELF) test in weighted linear regression analysis. Serum ferritin was significantly associated with both all liver-related outcomes (n = 92) and severe liver-related outcomes (n = 54) in weighted Cox regression analysis (hazard ratio [HR] per 1 SD, 1.11 [95% confidence interval (CI) 1.02-1.21]; p = 0.012 and HR 1.11 [95% CI 1.02-1.21]; p = 0.013, respectively). However, there was association neither between HFE risk variants and ELF test nor between HFE risk variants and liver-related outcomes. CONCLUSION: Serum ferritin levels were associated with liver fibrosis and incident liver disease, independent of HFE genotype in the general population. Furthermore, data demonstrated that metabolic disturbances and alcohol use were major risk factors for hyperferritinemia.

CONTEXT: There is limited data on the clinical significance of metabolic hyperferritinemia (MHF) based on the most recent consensus. OBJECTIVE: We aimed to validate the clinical outcomes of MHF in the general population and patients with biopsy-proven metabolic dysfunction-associated fatty liver disease (MAFLD). METHODS: The NHANES database and PERSONS cohort were included. MHF was defined as elevated serum ferritin with metabolic dysfunction (MD) and stratified into different grades according to ferritin (grade 1: 200 [females]/300 [males]-550â ng/mL; grade 2: 550-1000â ng/mL; grade 3: >1000â ng/mL). The clinical outcomes, including all-cause death, comorbidities, and liver histology, were compared between non-MHF and MHF in adjusted models. RESULTS: In NHANES, compared with non-MHF with MD, MHF was related to higher risks of advanced fibrosis (P = .036), elevated albumin-creatinine ratio (UACR, P = .001), and sarcopenia (P = .013). Although the association between all grades of MHF and mortality was insignificant (P = .122), grades 2/3 was associated with increased mortality (P = .029). When comparing with non-MHF without MD, the harmful effects of MHF were more significant in mortality (P < .001), elevated UACR (P < .001), cardiovascular disease (P = .028), and sarcopenia (P < .001). In the PERSONS cohort, MHF was associated with more advanced grades of steatosis (P < .001), lobular inflammation (P < .001), advanced fibrosis (P = .017), and more severe hepatocellular iron deposition (P < .001). CONCLUSION: Both in the general population and in at-risk individuals with MAFLD, MHF was related with poorer clinical outcomes.

INTRODUCTION: The distribution of causes of hyperferritinemia in international series is heterogeneous. Also, the association between ferritin and prognosis is controversial. This study aims to describe the diagnosis associated with hyperferritinemia in a retrospective cohort at an academic healthcare network in Chile. METHODS: A retrospective review of adult patients admitted to our academic medical center from June 2014 to February 2017 with ferritin ≥3,000 ng/mL. All patients were classified into nine diagnostic categories. Then, the association between ferritin level and disease category, as well as mortality, was evaluated. RESULTS: Ninety-nine patients were identified. The mean age was 50.8 ± 19.9 years, 54.5% were men. The most frequent categories were "inflammatory and autoimmune diseases" (21.2%) and "hematological malignancies" (19.2%). The average ferritin was 10,539 ± 13,016.9 ng/mL, while the higher mean was 16,707 ng/mL in the "inflammatory and autoimmune diseases" category. There was a statistically significant association between the ferritin value and age but not between ferritin and diagnostic categories. In the group over 50, hematologic neoplasms (19%) and infections (19%) were more frequent. In those under 50, inflammatory and autoimmune diseases were more frequent (26.8%). There was no association between the ferritin level and mortality at 1, 3, and 12 months. CONCLUSIONS: The most frequent categories were "inflammatory and autoimmune diseases" and "hematological malignancies", but ferritin level was similar in both. Further research could validate a prognostic role.
