The ANOVA analysis revealed no statistical difference among the serum ferritin means for each diagnosis ( P = .31). A normal serum transferrin saturation (ideally fasting) usually excludes iron overload (where it is raised) and suggests a reactive cause for raised ferritin. Think of your body as a kitchen pantry. identify common and uncommon conditions that can be associated with hyperferritinemia. The conditions associated with more extreme hyperferritinaemia are poorly understood.

A ferritin test helps your doctor understand how much iron your body is storing.If a ferritin test reveals that your blood ferritin level is lower than normal, it indicates your body's iron stores are low and you have iron deficiency.If a ferritin test shows higher than normal levels, it could indicate that you have a condition that causes your body to store too much iron. This test measures the amount of ferritin in the blood. The ferritin test is a simple blood test. Serum ferritin greater than 1,000 mcg/L indicates the … Ferritin is the major iron storage molecule in glial cells, particularly in oligodendrocytes (Gerber & Connor, 1989). Hemoglobinopathy was seen in 1% of hyperferritinemia cases overall and in the adult population, but not in any of the cases of pediatric hyperferritinemia. Some pathology companies use different ways to measure ferritin and so the “normal levels” may change a little. Katie Sackett, DO, MS, Maros Cunderlik, Nishant Sahni, MD, MS, Anthony A. Killeen, MD, PhD, Andrew P. J. Olson, MD, Extreme Hyperferritinemia:  Causes and Impact on Diagnostic Reasoning, American Journal of Clinical Pathology, Volume 145, Issue 5, May 2016, Pages 646–650, https://doi.org/10.1093/ajcp/aqw053. Mullally Do not be persuaded to … Da der Serum Ferritin Spiegel aber proportional zu dem Eisenspeicher der Zellen ist, gilt ers als Hauptindikator für einen Eisenmangel oder eine Eisenüberladung des Körpers. The patient medical record charts were reviewed and the primary diagnosis was determined by the authors’ expert review. Patienten mit genetisch bedingter Eisenüberladung werden mit Aderlass behandelt, bei sekundärer Eisenüberladung kommt eine Chelationstherapie infrage. Elevations in serum ferritin have been observed in common conditions, including sepsis due to bacterial, fungal or viral sources, or iron overload due to hemochromatosis or chronic transfusions, or as a general marker of inflammation. Primary HLH affected 11% of the pediatric population and only 1% of the adult population (3% overall). Most studies of hyperferritinaemia have focused on serum ferritin greater than 1000 μg/L, often in ambulatory patients. Elinder ; Low levels of ferritin are indicative of iron deficiency, which causes anemia (a reduction in the number of oxygen-carrying red blood cells). 12,13 The approach to a patient with hyperferritinemia should encompass not only the rarer entities described above, but should also include the more common and seemingly mundane differentials of infection and iron overload. There were 269 values (0.4%) over 10,000 ng/mL in 86 unique patients ranging from 10,006 ng/mL to 143,931 ng/mL. 1 The normal range of serum ferritin is gender and age specific, 7 to 10 ng/mL for infants and 20 to 300 ng/mL for adults. Low levels of ferritin are seen in iron deficiency.The body uses iron to produce the hemoglobin that is critical for the red blood cells to carry oxygen to the tissues of the body. N Although iron is important for lots of processes in the body, too much iron over a long period of time can be dangerous and cause a lot of problems with the function of body organs. LG The mean age of patients in this subgroup was 46.6 years. The primary diagnosis associated with hyperferritinemia that displayed the widest range of ferritin values was hematologic malignancy, with a range from 10,036 ng/mL to 143,931 ng/mL Figure 1 and Table 2 . The University of Minnesota has a robust bone marrow transplantation program, and thus such diagnoses may be overrepresented compared to other populations. Hereditary hemochromatosis, the most common cause of iron overload, is also called "bronze diabetes" because a patient's skin may be slate-colored, and diabetes occurs in approximately 65 percent of patients. It thus helps store iron in the body. View Our Locations page to quickly find your nearest Haematologist. Meyron-Holtz Some people have very high levels of serum ferritin – greater than 1000 ug/l. PLC. Go to your doctor and tell him you want tests. Coffman Hayward Melbourne Haematology is a group of clinical and laboratory trained specialist haematologists based in Melbourne dedicated to provide comprehensive management of patients with haematological disorders. Ferritin levels >1,000 mcg/L in women and 1,500 mcg/L in men (five times the upper limit of normal) have been associated with AOSD. The average ferritin value for each diagnosis is displayed in the descending order along with the error bars indicating 95% confidence interval computed using normal distribution. B Some people have very high levels of serum ferritin – greater than 1000 ug/l. . AC Ferritin is a protein that carries iron around in the blood and can be used to measure the amount of iron in the body. To further characterize the cases of hyperferritinemia associated with liver disease, patients classified into this category were divided according to whether they had either an acute or a chronic hepatic disease. Average serum ferritin by condition. a The majority of conditions associated with hyperferritinemia were chronic transfusion, followed by hematologic malignancy, liver disease (acute and chronic), with 11% or less associated with solid malignancies, hemoglobinopathy, infections, HLH and diagnosis not determined. Physicians should claim only the credit commensurate with the extent of their participation in the activity. The test helps your doctor to understand whether your ferritin levels are low or normal. CE G The cause of the hyperferritinemia was unable to be determined in 6% of pediatric (and 1% in overall) cases Table 1 . The information presented in this fact sheet is intended as a general guide only. et al.  Ferritin is the iron storage protein. If the levels are low, it indicates iron deficiency or other diseases. et al.  Ferritin is found chiefly in the cytoplasm of cells of the reticuloendothelial system and is a constituent of normal human serum. . When your ferritin levels are higher than 1,000 ng/mL, you may have a very high buildup of iron in your body. Ferritin is the storage form of iron in the liver. High levels of ferritin can indicate an iron storage disorder, such as hemochromatosis, or a chronic disease process. Ferritin levels in the basal ganglia and the cortex closely match with the distribution of iron. Instead, common clinical conditions, including liver disease, iron overload and malignancy are much more likely in patients with hyperferritinemia. Copyright © 2021 American Society for Clinical Pathology. Allen Sahni The primary diagnosis in the majority of cases in both the pediatric and adult populations with hyperferritinemia was iron overload from chronic transfusions (35% total, 37% pediatric, 34% adult). Samuelsson-Horne Bacterial, viral and fungal infections displayed ranges from 11,300 ng/mL to 25,460 ng/mL, 14,037 ng/mL to 72,710 ng/mL and 18,349 (one patient), respectively. Henter of patients). One adult patient had hyperferritinemia associated with a Babesia infection, categorized as “Infection–Other,” and comprised 1% of the adult and overall population of this subset. Those with hyperferritinemia associated with liver disease showed a range from 10,877 ng/mL to 93,103 ng/mL. Ferritin is an intracellular iron storage protein and a marker of iron stores. These people will generally need some form of treatment for the high levels of ferritin. Upon completion of this activity you will be able to: describe ferritin’s normal physiologic function. infections, inflammatory conditions such as arthritis). High level of ferritin usually represents high level of iron, and it may has various causes. Methods: We identified conditions most associated with hyperferritinemia by identifying 65,536 serum ferritin levels at the University of Minnesota Hospital over a five-year period, with 86 values higher than 10,000 ng/mL. M . Solid malignancies were associated with hyperferritinemia in 2% of overall cases, 3% of adult cases, and none of the pediatric cases. The protein is produced by almost all living organisms, including archaea, bacteria, algae, higher plants, and animals. Results: The majority of cases in both populations with hyperferritinemia were due to chronic transfusion (35%), followed by liver disease (27%), and hematologic malignancy (16%). Kim The one patient with hyperferritinemia associated with a hemoglobinopathy had a ferritin value of 14,526 ng/mL. ... Ein Ferritinspiegel über 500 oder 1000 ng/ml ist schwerwiegend und weist auf eine abnormale Anhäufung von Eisen im Organismus hin. Unexplained serum ferritin values >1000 μg/L warrant referral for further investigation. .  The authors of this article and the planning committee members and staff have no relevant financial relationships with commercial interests to disclose.

If the ferritin is low, this often means the body is low in iron. Development and dissemination of the national strategic action plan for reducing inappropriate polypharmacy in older Australians. et al.  This was followed by liver disease (27% total, 11% pediatric, 31% adult), and hematologic malignancies (16% total, 21% pediatric, 15% adult). , et al.  Conclusions: Although this supports the relationship between extreme hyperferritinemia and HLH, it maintains that the positive predictive value of hyperferritinemia for HLH is quite low, and one should consider more common explanations before suspecting HLH. Ferritin is a blood cell protein that contains iron. 11 While a high index of suspicion is necessary to avoid missing rare diagnoses, care must be taken to avoid overtesting and overdiagnosis of HLH based on serum ferritin levels alone. With Institutional Review Board (IRB) approval, all serum ferritin values measured at the University of Minnesota Medical Center laboratory between February 1, 2007, and February 23, 2012, were imported from the medical records system database into a Microsoft Excel data file for further analysis. Unexplained serum ferritin values >1000 μg/L warrant referral for further investigation. A First, this was a retrospective chart review study, and diagnoses were drawn from clinical documentation and may be subject to error. In humans, it acts as a buffer against iron deficiency and iron overload. Of those with acute liver disease associated with hyperferritinemia, 11% overall (nine patients) had acute liver disease, with 10% (seven) being adults, and 11% (two) being children. My ferritin reached 800 and I have had countless problems from it being stored around the body. Moore Primary HLH displayed a range from 10,214 ng/mL to 33,000 ng/mL, while sHLH ranged from 10,548 ng/mL to 27,880 ng/mL. GidgetD 07/14/2010. Söder Bennett 7 Despite the fact that HLH is rare and multiple recent articles have suggested that the positive predictive value of extreme hyperferritemia is poor, clinicians still have a reflexive association between extreme hyperferritinemia (levels >10,000 ng/mL) and HLH in their diagnostic reasoning. et al.  Our primary aim was to determine the primary clinical cause of extreme hyperferritinemia in a tertiary care population over a five-year period. Objectives: Hyperferritinemia can be a result of inflammation, infection, chronic iron overload, or other uncommon pathologies including hemophagocytic lymphohistiocytosis (HLH). Elevated ferritin is also observed in acute and chronic liver disease, chronic renal failure, and in … Measurement of ferritin in blood helps know the iron levels. The diagnostic criteria for HLH must include five of these eight findings: hyperferritinemia, fever, splenomegaly, bicytopenia, elevated triglycerides and/or decreased fibrinogen, hemophagocytosis identified (usually in a bone marrow, liver or lymph node specimen), decreased or absent NK cell function, and increased soluble IL-2 receptor. In the adult population, sHLH comprised 7% of cases of hyperferritinemia (6% of all subjects), but was not seen in any of the hyperferritinemia cases in children. . C The distribution of ferritin values across ranges is shown in Table 3 . 1. It has a molecular weight of ≥ 440000 daltons, depending upon the iron content, and consists of a protein shell (apoferritin) of 24 subunits and an iron core containing an average of approx. HLH, hemophagocytic lymphohistiocytosis. et al.  KN Some pathology companies use different ways to measure ferritin and so the “normal levels” may change a little. et al.  The number of iron atoms/ferritin cage is said to average 1000–1500 normally, 73 governed more by iron availability than anything else, with a maximum of 4500 iron atoms normally being quoted (e.g., ref. , Suspected adult-onset Still's disease (AOSD)- an increase in serum ferritin level may be suggestive of AOSD. name the eight diagnostic criteria used to identify hemophagocytic lymphohistiocytosis. I started donating blood in January 2013. Increased levels of serum ferritin may occur for a number of reasons. 90–92, and attained for iron overload conditions or when loaded artificially in vitro). There is a historical association between extreme hyperferritinemia and HLH, but in reality HLH is associated with a minority of hyperferritinemic states. This is usually related to a condition called. EG Ferritin is a molecule that has many roles, ranging from the binding and storage of iron to contributing to inflammation, cell signaling and immune function. A ferritin test measures the amount of a blood protein called ferritin, which stores iron. My ferritin count was 1300 ug/l, AST 56, ALT 64, and blood pressure (BP) 130/90 with medications. The concentration of ferritin is directly proportional to the total iron stores in the body, resulting in serum ferritin concentrations becoming a common diagnostic tool … JI Today, June 1, 2015 ferritin count is 246, BP is 115/75, HDL/LDL all within range; heaven knows who my blood helped, but they are out there. OBJECTIVE —A high prevalence of diabetes has been reported in patients with hepatitis C virus (HCV) infection. S The percentage of total patients who had hyperferritinemia associated with viral, bacterial, or fungal infections (2%, 3%, and 1%, respectively) is likely consistent with other populations. et al.  Having a liver condition can promote the accumulation of ferritin, but also high ferritin can cause harm to the liver. Percentage of Conditions Associated With Hyperferritinemia a. HLH, hemophagocytic lymphohistiocytosis. M The clinical significance of extreme hyperferritinaemia has come under scrutiny with the increasing recognition of haemophagocytic lymphohistiocytosis (HLH) in adults. , Centers for Disease Control and Prevention. Overall, bacterial, fungal, and viral infections accounted for 3%, 1% and 2% of overall cases, respectively. Data are given as percent (No. Ferritin isn’t the same thing as iron. Based on the authors’ review, diagnoses were classified into the following categories: “Chronic Transfusion,” “Liver Disease,” “Malignancy—Hematologic,” “Malignancy–Solid,” “Hemoglobinopathy,” “Infection—Bacterial,” “Infection—Fungal,” “Infection–Viral,” “Infection—Other,” “Primary HLH,” “Secondary HLH,” “Macrophage Activation Syndrome,” and “Diagnosis Not Determined.” HLH-2004 criteria as defined by Henter et al 7 were used for the determination of HLH diagnosis. Bacterial, fungal, and viral infections were associated with hyperferritinemia in adults in 3%, 1%, and 0%, respectively; in children, 5% of cases were associated with bacterial infection, 11% with viral infections, and no cases were associated with fungal infection. Aricó MB Serum ferritin of <1,000 ng/mL at diagnosis remains an important diagnostic test to identify patients with a low risk of advanced hepatic fibrosis and should be used routinely as part of the initial diagnostic evaluation. Anticoagulation - Rivaroxaban (Xarelto®) or apixaban (Eliquis®), Bone Marrow Biopsy - Post Procedure Instruction, Hereditary Haemorrhagic Telangiectasia (HHT), Peri-operative management of anticoagulation, Fatigue Severity Scale (FSS) - Questionnaire, Idiopathic Thrombocytopenia Purpura (ITP) in Children, Idiopathic Thrombocytopenia Purpura (ITP) in Adults, MGUS (monoclonal gammopathy of undetermined significance), Anticoagulation - Being on long-term anticoagulation medication rivaroxaban (Xarelto®) or apixaban (Eliquis®), Iron Infusion with ferric carboxymaltose (FCM), Anticoagulation (Blood thinning) in Pregnancy, Below Knee DVT - Calf vein thrombosis (Distal deep vein thrombosis (DVT), Peri-operative management of anticoagulation (blood thinning), Increased levels may also be seen in problems with the liver (hepatitis), Excessive alcohol can also increase the levels of serum ferritin, A major cause of raised serum ferritin is when there is too much iron in the body. Hyperferritinemia associated with solid malignancy displayed a range from 13,613 ng/mL to 14,754 ng/mL. Extreme hyperferritinemia (defined as a ferritin level >10,000 ng/mL) often triggers a thought process that includes many rare and serious differential diagnoses such as HLH, while more common disorders are dismissed. Olson . Patients were categorized as adult if their age was greater than 18 years on the date of the ferritin value measurement. , 5,6. In addition, there may be local institutional and epidemiological characteristics that make the data less generalizable: for example, the one case of hyperferritinemia associated with a Babesia infection may be less geographically generalizable, as this parasite is more endemic in geographic locations such as the Midwest and Northeast. Pediatric patients comprised 22% of this population, and adults, 78%. . These tests try and find a reason why the serum ferritin is high and then treatment, if necessary, can be arranged. In patients with … Consider HFE mutation screen for hereditary haemochromatosis in individuals with elevated ferritin and a raised transferrin saturation >45%. CE For a female the normal level is 15 – 200 ug/l. JA MA This activity qualifies as an American Board of Pathology Maintenance of Certification Part II Self-Assessment Module. Classically, a very limited differential diagnosis has been considered for patients with such extreme hyperferritemia, including sepsis, infection (especially fungal), and iron overload, and rare causes such as hemophagocytic lymphohistocytosis (HLH). C  The ASCP is accredited by the Accreditation Council for Continuing Medical Education to provide continuing medical education for physicians. Melbourne Haematology currently has over 30 Haematologists practicising in over 20 locations throughout Melbourne and surrounding suburbs including Geelong. Aricò 4 HLH is an uncommon disorder that affects approximately 1:50,000 patients per year. Patients who had hyperferritinemia associated with chronic transfusions (30 in total) had serum ferritin values that fell in the lower half of the hyperferritinemic range (<59,000 ng/mL), while the remaining diagnoses displayed a wider range of ferritin values. Also your ferritin levels need to be monitored serially and if found to be raised persistantly above 1000 (which suggests a liver damage is inevitable), than phlebotomy is … Erhöhtes Ferritin bedeutet einen Überschuss dieses Proteins, das der Eisenspeicherung dient, im Körper. Liegt dieses über dem alters- und geschlechtsspezifischen Normwert, ist das Ferritin zu hoch. Patients with hyperferritinemia associated with a hematologic malignancy displayed not only the widest range of serum ferritin values (10,036 ng/mL to 143,931 ng/mL), but also boasted the highest ferritin values, with the two ranges that were greater than 100,000 ng/mL. Also known simply as a "ferritin test" or a "serum ferritin level," the test has been available since the 1970s. Treatment of HLH often involves administration of cytotoxic chemotherapy, and thus a high diagnostic threshold must be used, given the potential for side effects and complications stemming from treatment. Campigotto A number of blood tests and an ultrasound to look at the liver are usually needed in people who have high serum ferritin. APJ This blood test indirectly provides information about whether there is too much or too little iron available in your body. While there is interest in iron reduction therapy for cancer risk reduction,3 improvement of insulin sensitivity in metabolic syndrome4 and management of fatty liver disease not responding to lifestyle changes,5 the Australian Red Cross Blood Service Therapeutic Venesection program is currently restricted to patients meeting the criteria listed in Table 1, and who also meet the general eligibility criteria for volunteer blood donation.
