Screening for Wilson's disease in patients with liver diseases by serum ceruloplasmin. Diagnosis Role for Biochemical Assays and Kayser-Fleischer Rings in Diagnosis of Wilson's Disease. Diagnostic value of ceruloplasmin in the diagnosis of pediatric Wilson's disease. Serum ceruloplasmin levels in children with Wilsons disease , a total of 317 children were diagnosed as WD in GWCMC in last 11 years, 200 (63.1%) boys and 117 (36.9%) girls. Wilson's Disease -, Merle U, Schaefer M, Ferenci P, Stremmel W. Clinical presentation, diagnosis and long-term outcome of Wilson's disease: a cohort study. Mutational analysis of exon 8 and exon 14 of ATP7B gene in Bangladeshi children with Wilson disease. Prognosis for patients with Wilson disease is usually good, unless disease is advanced before treatment begins. Serum ceruloplasmin (normally 20 to 35 mg/dL [200 to 350 mg/L]) is usually low in Wilson disease but can be normal. These healthy children were partitioned into 16 age subgroups. Some copper is deposited around the rim of the cornea and edge of the iris, causing Kayser-Fleischer rings. o [teenager OR adolescent ], , MD, PhD, University of Arkansas for Medical Sciences, (See also Overview of Mineral Deficiency and Toxicity Overview of Minerals Six macrominerals are required by people in gram amounts. Muller T, Koppikar S, Taylor RM, et al. This cutoff value had the highest AUC value (0.99), a sensitivity of 97.0%, and a specificity of 96.1%. Four cations: Sodium, potassium, calcium, and magnesium Two accompanying anions: Chloride and phosphorus Daily requirements range from read more .). In terms of clinical phenotype, serum ceruloplasmin levels were significantly higher in the hepatic subtype than in the asymptomatic subtype. In all the screened patients, the diagnosis of WD was based on a Leipzig score of 4 or more (3). Sometimes the CNS symptoms are cognitive or psychiatric abnormalities. To overcome the diagnostic challenge, several clinical signs (Kayser-Fleischer rings, neurologic symptoms) and laboratory features (copper in serum, urine, liver; serum ceruloplasmin; genetic testing) are scored 0 (absent) to 2 (present) and the Leipzig score is calculated. The objective of this study was to determine the optimal cutoff value of serum ceruloplasmin levels for the diagnosis of WD in a large Chinese cohort and to identify factors associated with serum ceruloplasmin. Clinical manifestations of Wilson disease in organs other than the liver and brain. Epub 2022 Sep 9. An official website of the United States government. Cheng N, Wang H, Wu W, Yang R, Liu L, Han Y, et al.. (2008) 47:2089111. It has been reported that in the patients with acute liver failure, the conventional cutoff of serum ceruloplasmin level at 20mg/dL only provided a diagnostic sensitivity of 21% and specificity of 84% for WD [22, 25]. Other study reported that truncating mutations in the ATP7B gene are also associated with very low serum ceruloplasmin level and an early onset of WD [27]. This study aims to assess diagnostic value of serum ceruloplasmin level for WD in children up to age of 15years. The ROC curve suggested that the cutoff value of serum ceruloplasmin level of 16.85mg/dL gave the highest diagnostic accuracy for WD with elevated aminotransferases (Fig. The positive and negative predictive values were 80.8% and 98.7%, respectively. In addition, some studies observed lower serum ceruloplasmin levels in patients with R778L homozygous mutations than in patients without R778L mutations (21). government site. Screening consists of a slit-lamp examination and measurement of transaminase levels, serum copper and ceruloplasmin, and 24-hour urine copper excretion. Wilson disease is an autosomal recessive metabolic disorder in which impaired copper excretion causes copper to accumulate in the body. Measurement of serum ceruloplasmin level is the first step in screening for Wilson's disease (WD). In the present study, the ROC curve analyses showed the optimal cutoff value of serum ceruloplasmin is 16.85mg/dL, with a sensitivity of 95.9% and specificity of 93.6% for diagnosis of WD in children. Of 261 asymptomatic WD children, serum ceruloplasmin was significantly lower and the age at diagnosis was much younger while compared with 56 WD children with various clinical symptoms and signs (p<0.05, p<0.001). 8600 Rockville Pike (2003) 23:13942. Wilson disease with hepatic presentation in an eight-month-old boy. The most common etiologies of false positivity in the present study were non-WD hepatitis, liver failure, nephrotic syndrome, and heterozygous relatives. WebWilson disease is a rare genetic condition that occurs when your body accumulates too much copper, especially in the liver and brain. Therefore, the use of low reference limit for serum ceruloplasmin may lead to unacceptably high numbers of false-positives, which may trigger further investigations and overtreatments. 8600 Rockville Pike Our results were consistent with previous reports, indicating that serum ceruloplasmin is not suitable for newborn screening [7, 1618]. Molecular studies of ceruloplasmin deficiency The KruskalWallis test and the post hoc test were used to compare differences among three or more groups. However, the lower reference limit varies with assay methodologies and the individuals in the included studies. Through a literature review, we found that five studies evaluated the thresholds of ceruloplasmin, which ranged from 0.14 to 0.19 g/L. A position paper by the hepatology committee of the European society for paediatric gastroenterology, hepatology and nutrition. It is interesting to find healthy boys had significantly higher level of serum ceruloplasmin than the girls, so did in asymptomatic WD patients (Fig. All patients who underwent a serum ceruloplasmin test from 1 January 2016 to 2 September 2019 in the First Affiliated Hospital of Anhui University of Chinese Medicine were eligible for this study. Murillo O, Collantes M, Gazquez C, Moreno D, Hernandez-Alcoceba R, Barberia M, Ecay M, Tamarit B, Douar A, Ferrer V, Combal JP, Peuelas I, Bnichou B, Gonzalez-Aseguinolaza G. Mol Ther Methods Clin Dev. After 1 to 5 years of therapy, lower dose maintenance drug therapy can be considered. A total of 6 (1.9%) in 317 WD patients had normal value of serum ceruloplasmin>20mg/dL, all of whom were asymptomatic (6/261, 2.3%). Epub 2014 Mar 20. The mean level of serum ceruloplasmin in these healthy controls was 30.77.8mg/dL. Effect of clinical phenotypes on serum ceruloplasmin levels of patients with WD. Ferenci et al. All non-WD patients had serum ceruloplasmin level>20mg/dL, with the mean level of serum ceruloplasmin (28.611.8mg/dL) much higher than that in WD patients (p<0.001), but lower than healthy controls (p<0.001). Cross-reactivity may occur in people with penicillin allergy. 1). Serum ceruloplasmin levels in WD children carrying R778L mutation, *Represents statistical significance of serum ceruloplasmin between WD children with and without R778L, p value<0.05. Age and gender specific pediatric reference intervals for aldolase, amylase, ceruloplasmin, creatine kinase, pancreatic amylase, prealbumin, and uric acid. Serum ceruloplasmin level was measured in 154 patients with non-WD diseases, including acute liver failure, viral hepatitis and nephrotic syndrome. The impaired transport decreases copper secretion into the bile, thus causing the copper overload and resultant accumulation in the liver, which begins at birth. Hepatic fibrosis develops, ultimately causing cirrhosis. WebYou may need a ceruloplasmin test if you have a family history of Wilson's disease. proposed a conventional diagnostic scoring system for WD, including low serum ceruloplasmin levels, elevated urinary copper excretion, KF ring, liver copper content and genetic findings [2]. Suspect the disorder in people with a family history of the disorder or unexplained hepatic, neurologic, or psychiatric abnormalities (including elevated transaminase levels). Yellowish skin or eyes . Sezer OB, Perk P, Honut F, Kse SK, zcay F. Is it necessary to re-evaluate diagnostic criteria for Wilson disease in children? These results confirm that a ceruloplasmin level <0.20 g/L is unsuitable as the optimal cutoff value for the diagnosis of WD. Zinc acetate 50 mg orally 3 times a day can reduce intestinal copper absorption, thus preventing reaccumulation of copper in patients who cannot tolerate penicillamine or trientine or who have neurologic symptoms that do not respond to the other drugs. and transmitted securely. Early and presymptomatic detection of Wilson's disease at the mandatory 3-year-old medical health care examination in Hokkaido Prefecture with the use of a novel automated urinary ceruloplasmin assay. Unable to load your collection due to an error, Unable to load your delegates due to an error. Moreover, the significance of many mutations that occur in the ATP7B gene is undetermined (5). Age specific reference value of serum ceruloplasmin level was analyzed (Table (Table11 and Fig. Overall, the optimal cutoff of 0.13 g/L provided both higher specificity and accuracy than the conventional cutoff level of 0.20 g/L. Wilsons disease (WD) is an autosomal recessive disorder of copper metabolism caused by mutations in the ATP7B gene [1]. Accessibility Liver biopsy results will show high copper content. See this image and copyright information in PMC. In our previous study, we have noticed that serum ceruloplasmin level is decreased in the majority of WD children [15]. Copper diffuses out of the liver into the blood, then into other tissues. suggested that WD should be highly suspected with serum ceruloplasmin level<10mg/dl in children [7]. We divided the derivation and validation cohorts based on the time point of 30 August 2016. (3) proposed a scoring system for the diagnosis of WD (Leipzig score) that was based on a combination of clinical manifestations, laboratory tests, and genetic analysis. The objective of this study was to determine the optimal cutoff value of serum ceruloplasmin levels for the diagnosis of WD in a large Chinese cohort and identify factors associated with serum ceruloplasmin. Hepatic or neurologic symptoms develop. With respect to the age of symptom onset, the serum ceruloplasmin level was lower in early-onset patients and higher in late-onset patients. WebThe diagnosis of Wilson disease is made by relatively simple tests. The optimal threshold of serum ceruloplasmin in the diagnosis of Wilson's disease: a large hospital-based study. Garca-Villarreal L, Hernndez-Ortega A, Snchez-Monteagudo A, et al. In patients with clinical features suggestive of Wilson disease (eg, abnormal liver tests combined with neurologic symptoms), we start by obtaining liver biochemical tests, a complete blood count, serum ceruloplasmin and copper levels, an ocular slit-lamp examination (or optical tomography), and a 24-hour urinary copper excretion. Conventionally, serum ceruloplasmin levels below the lower reference limit (0. Age and gender difference of serum ceruloplasmin remain controversy. Composition of controls group in validation cohort and their serum ceruloplasmin levels. 24-hour urine copper test. The cutoff value of serum ceruloplasmin level at 16.8mg/dL may provide the highest accuracy for diagnosis of WD. Socha et al. Methods: All data generated or analyzed during this study are available from the corresponding author on reasonable request. diagnosis Steindl P, Ferenci P, Dienes HP, et al. Federal government websites often end in .gov or .mil. MeSH Background: When a cutoff value of 0.13 g/L was used in the validation cohort, 197 patients with WD and 105 controls were correctly identified, with a sensitivity of 97.0%, a specificity of 95.5%, and an accuracy of 96.5%. Diagnosis is based on a low serum ceruloplasmin level, high urinary excretion of copper, and sometimes liver biopsy results. EASL Clinical Practice Guidelines: Wilson's disease. Diagnosis and phenotypic classification of Wilson disease. National Library of Medicine WD patients with R778L homozygotes exhibited lower levels of serum ceruloplasmin than the patients without R778L (p<0.05). sharing sensitive information, make sure youre on a federal Your body needs a small amount of copper from food to stay healthy, but without treatment, Wilson disease can lead to high copper levels that cause life-threatening organ damage. Kim JW, Kim JH, Seo JK, et al. Consistent with the reports from other studies from China and South Korea, our findings indicates that decreased level of serum ceruloplasmin is strongly reflecting the abnormality of copper metabolism and the potential diagnosis of WD [6, 12]. Therefore, it is important to establish the age and gender specific reference of serum ceruloplasmin levels in healthy children, and evaluate the diagnostic criteria of serum ceruloplasmin level for WD during early childhood. For asymptomatic siblings of index patients, mutation analysis is the most reliable approach. WebDiagnosis may be difficult and often involves a combination of blood tests, urine tests and a liver biopsy. Korman J, Volenberg I, Balko J, et al. If the score is 4, the diagnosis of Wilson disease is very likely. In unclear cases (eg, elevated transaminases, no Kayser-Fleischer rings, indeterminate values for ceruloplasmin and urinary copper), the diagnosis is made by doing a liver biopsy to measure hepatic copper concentration. (A), Effect of common ATP7B genotypes on serum ceruloplasmin levels of patients with WD., MeSH The impaired transport also interferes with incorporation of copper into the copper protein ceruloplasmin, thus decreasing serum levels of ceruloplasmin. The conventional ceruloplasmin cutoff of <0.20 g/L was used, and WD was diagnosed in 1,275 patients, with a sensitivity of 99.8%, a specificity of 69.5%, and an accuracy of 81.9%. FOIA A low ceruloplasmin level in a patient with a Kayser-Fleischer ring is diagnostic. Ceruloplasmin (2012) 56:67185. Genomic DNA was extracted from peripheral blood samples. Diagnosis and phenotypic classification of Wilson disease. All authors reviewed and agreed to publication of the final version of the manuscript. DF Box and whisker plots show the values of serum ceruloplasmin in all WD and non-WD patients (D), the patients with acute liver failure and the patients (E) with elevated aminotransferases (F). In 1952, Scheinberg and Gitlin first reported that serum ceruloplasmin is deficient in patients with WD (7). With the application of Ferenci scoring system, WD can be identified and diagnosed easily when the patients present with typical symptoms. Spectrum of ATP7B mutations and genotype-phenotype correlation in large-scale Chinese patients with Wilson Disease, Mutation analysis of the ATP7B gene and genotype-phenotype correlation in Chinese patients with Wilson disease.

Unable to load your collection due to an error, Unable to load your delegates due to an error. It is controversial for optimal cutoff value of serum ceruloplasmin levels for diagnosis of WD, which is from 11.5mg/dL to 20mg/dL [913, 25]. Therefore, as the second part of our study, we identified factors associated with serum ceruloplasmin. Rarely, these rings occur in other liver disorders (eg, biliary atresia, primary biliary cirrhosis), but ceruloplasmin levels should be unaffected. Age specific difference of serum ceruloplasmin level in WD patients was analyzed (Table (Table11 and Fig. If levels are equivocal, measuring urinary copper excretion after penicillamine is given (penicillamine provocation test) may confirm the diagnosis; this test is not usually done in adults because cutoff values are not well-established. Moreover, no significant difference was detected in ceruloplasmin levels in WD patients with or without KF rings (6). Please enable it to take advantage of the complete set of features! Merle U, Weiss KH, Eisenbach C, et al. 8600 Rockville Pike Statistical analyses were performed using SPSS (version 25; SPSS Inc., Chicago, IL, USA) and GraphPad Prism (version 7.0; GraphPad Software, La Jolla, California, USA). 81973825, 81903895, and 82205076), Collaborative Innovation Project of Anhui Colleges and Universities (No. Trientine hydrochloride, also a chelating drug, is an alternative treatment to penicillamine. ceruloplasmin However, the lower reference limit varies with assay methodologies and the individuals in the included studies. (11) recommended that each laboratory should establish a cutoff value of serum ceruloplasmin levels for the diagnosis of WD according to the local population, rather than using the lower reference limit. Socha P, Janczyk W, Dhawan A, et al. Dong Y, Wang RM, Yang GM, Yu H, Xu WQ, Xie JJ, Zhang Y, Chen YC, Ni W, Wu ZY. Diagnosis 2015. 10.1136/gut.2005.087262 FOIA Serum ceruloplasmin levels were significantly lower in the patients with WD (0.029 g/L, IQR 0.016~0.052) than in the heterozygous relatives (0.153 g/L, IQR 0.130~0.182) and non-WD patients with liver dysfunction (0.242 g/L, IQR 0.196~0.288), neurological deficits (0.225 g/L, IQR 0.188~0.266), and other diseases (0.246 g/L, IQR 0.206~0.292; Figure 1A). (20) discovered that higher serum ceruloplasmin levels indicated a greater possibility of the hepatic subtype, while lower serum ceruloplasmin levels were associated with the neurological subtype. Wiernicka A, Ddalski M, Jaczyk W, et al. Clin Gastroenterol Hepatol. The ratio of male to female in WD patients was 1.7:1. WebKey Points. Unauthorized use of these marks is strictly prohibited.

The online version contains supplementary material available at 10.1186/s12876-022-02186-0. Therefore, some studies have attempted to determine the cutoff value of serum ceruloplasmin levels for the diagnosis of WD based on the local population. ceruloplasmin Clinical presentations of Wilson disease. In Wilson disease, 24-hour urinary copper excretion (normally, 30 mcg/day) is usually > 100 mcg/day. As a library, NLM provides access to scientific literature. Heterozygous group (n=21) included unaffected siblings carrying one pathogenic mutation in the ATP7B gene. Korman JD, Volenberg I, Balko J, Webster J, Schiodt FV, Squires RH Jr, et al.. The https:// ensures that you are connecting to the Among the heterozygous patients, the patients with PAV/PAV had higher serum ceruloplasmin levels than those with PTV/PAV. Copper gets deposited in different organs, and the spectrum of clinical manifestations varies from progressive hepatic damage and neurological deterioration to atypical cardiac and osteoarticular involvement (2). Clifford SM, Bunker AM, Jacobsen JR, et al. 2018 Dec;42(6):512-520. doi: 10.1016/j.clinre.2018.03.007. Disclaimer. Recently, a systematic review of the use of the ceruloplasmin test for the diagnosis of WD indicated key biases in participant selection and reference standards, which indicate that the cutoff used for ceruloplasmin requires external validation (17). eCollection 2022. However, it is a cumbersome and costly test. It is most destructive to the brain but also damages the kidneys and reproductive organs and causes hemolytic anemia. Serum ceruloplasmin levels were measured in 317 WD patients, 21 heterozygotes, 372 healthy control children and 154 non-WD patients with other liver diseases. Wilsons disease (WD) is a rare autosomal recessive disorder of hepatocellular copper deposition. Schonfeld EA, Brown RS., Jr Genetic testing in liver disease: what to order, in whom, and when. However, false-negative results may occur because of a sampling error (due to large variations in copper concentrations in the liver) or fulminant hepatitis (causing necrosis that releases large amounts of copper). Merle U, Eisenbach C, Weiss KH, Tuma S, Stremmel W. Serum ceruloplasmin oxidase activity is a sensitive and highly specific diagnostic marker for Wilson's disease, Biomarkers for diagnosis of Wilson's disease. http://creativecommons.org/licenses/by/4.0/, http://creativecommons.org/publicdomain/zero/1.0/. The optimal cutoff of the serum ceruloplasmin level for separating patients with WD from other participants was 0.13 g/L, as determined by ROC analysis. There was no significant gender difference of serum ceruloplasmin among 317 WD patients and inside each age subgroup (Fig. WH, TW, LT, YulY, NQ, and HX were responsible for sample collection and identifying clinical information. None of WD patients with acute liver failure had serum ceruloplasmin level>20mg/dL. Further studies demonstrated that low serum ceruloplasmin levels provided strong evidence for the diagnosis of WD, so the measurement of serum ceruloplasmin levels was recommended as the first step in screening for WD (8, 9). Hahn S. Population screening for Wilson's disease. Serum ceruloplasmin level is typically decreased in most of WD patients, but not in all of them. In addition, some studies have sought to evaluate whether serum ceruloplasmin levels are associated with a particular phenotype/genotype of the disease. The ROC curve has been used to investigate the optimal cutoff value of serum ceruloplasmin for early diagnosis of WD. 2014 Jul;8(5):513-20. doi: 10.1586/17474124.2014.899898. 20 g/L) is considered a diagnostic cutoff point for Wilson's disease (WD). sharing sensitive information, make sure youre on a federal Careers.
