Wilson?s disease presenting as rapid eye movement sleep behavior disorder: a possible window to early treatment / Doença de Wilson apresentando-se com transtorno comportamental do sono REM: uma janela possível para instituição de tratamento precoce

Objective To describe characteristics of REM sleep behavior disorder in Wilson’s disease. Method Questionnaire-based interviews (patients and relatives), neurological examinations, two-week prospective dream-diary, video-polysomnography, transcranial sonography, MRI. Results Four Wilson’s disease cases with REM sleep behavior disorder were described; three had REM sleep behavior disorder as initial symptom. All showed mesencephalic tegmental/tectal sonographic hyperechogenicities and two presented ponto-mesencephalic tegmental MRI hyperintensities. Conclusion This first description of REM sleep behavior disorder in Wilson’s disease in literature documents REM sleep behavior disorder as a possible presenting symptom of Wilson’s disease and adds further evidence to the parallelism of Parkinson’s disease and Wilson’s disease in phenotype and brainstem topography, which ought to be further studied. REM sleep behavior disorder has prognostic relevance for neurodegeneration in α-synucleinopathies. In Wilson’s disease, usefulness of early diagnosis and treatment are already well established. REM sleep behavior disorder in Wilson’s disease offers a possible theoretical model for potential early treatment in this extrapyramidal and brainstem paradigm syndrome, previewing the possibility of neuroprotective treatment for REM sleep behavior disorder in “pre-clinical” Parkinson’s disease. .

Objetivo Descrever características do transtorno comportamental do sono REM (TCSR) na doença de Wilson (DW). Método Aplicação de entrevistas, vídeo-polissonografia, sonografia transcraniana (STC), ressonância magnética (RM), diário de sonhos. Resultados Descrevemos quatro casos de DW com TCSR. Três apresentaram o TCSR como primeira manifestação. Todos mostraram hiperecogenicidades mesencefálicas na STC, dois apresentaram hiperintensidades ponto-mesencefálicas na RM. Conclusão Esta é a primeira descrição do TCSR na DW. Relatamos o TCSR como um sintoma inicial da DW. Acrescentamos prova para o paralelismo entre a doença de Parkinson e DW, com relação aos fenótipos e localização das lesões cerebrais. Nas alfa-sinucleinopatias, o TCSR tem relevância prognóstica quanto à neurodegeneração. Na DW, já conhecemos a importância de diagnóstico e tratamento precoces. O TCSR na DW oferece um modelo para antecipar o tratamento desta síndrome de acometimento dos núcleos basais e tronco, vislumbrando a possibilidade de tratamento neuroprotetor para a fase “pré-clínica” da DP. .

Zinc-Induced Gastric Ulcer: Case Report on Two Patients with Wilson’s Disease.

Zinc has been developed as an effective and nontoxic therapy in Wilson’s disease. Zinc salts are generally well tolerated. Mild gastrointestinal discomfort is the major observed side effect and may be dependent on the zinc salt employed. Here, we report two Wilson’s disease patients who presented with severe gastric ulceration few months after beginning treatment with zinc acetate 50 mg three times a day. Our patients were not taking any ulcerogenic drugs and had no evidence of Helicobacter pylori infection. In both patients, zinc acetate was replaced by penicillamine and proton pump inhibitor therapy was initiated with complete resolution of gastrointestinal symptoms. To our knowledge, this is the first report of zinc acetate-induced gastric ulceration, which should be looked for in Wilson’s disease patients who develop abdominal discomfort while on this drug.

Tratamiento de la enfermedad de Wilson durante el embarazo: primer caso reportado en Cuba / Treatment of Wilson disease during pregnancy. First case reported in Cuba

Se presenta el primer caso en Cuba de una gestante con diagnóstico de enfermedad de Wilson atendida en la consulta integral para embarazadas del Policlínico Comunitario Docente Sur de Ciego de Ávila; se describe el tratamiento que se debe realizar en estas pacientes.

Wilson disease or hepatolenticular degeneration, is a copper metabolism disorder that is inherited by autosomal recessive form; its incidence at global level is 1 of each 30,000 inhabitants. The first case of a pregnant woman in Cuba with diagnosis of Wilson disease attended in the integral consultation for pregnant women from Community Polyclinic of the south area of Ciego de Avila; the treatment that is due to make in these patients is described.

Wilson's disease: an analysis of 28 Brazilian children

OBJECTIVES: Clinical-laboratory and evolutionary analysis of twenty-eight patients with Wilson's disease. METHODS: Twenty-eight children (twelve females and sixteen males) with Wilson's disease were evaluated retrospectively between 1987 and 2009, with a follow-up of 72 months (1 - 240 months). The clinical, laboratory, and histologic features at diagnosis were recorded at the end of the study. RESULTS: The median age at diagnosis was 11 years (2 - 18 years). Twelve patients were asymptomatic, seven had hepatitis symptoms, five had raised aminotransferase levels, three had hepatomegaly associated with neurological disorders, one had fulminant hepatitis with hemolytic anemia, and six patients presented with a Kayser-Fleischer ring. A histological analysis revealed that six children had chronic hepatitis, seven had cirrhosis, two had steatosis, one had portal fibrosis, and one had massive necrosis. The treatment consisted of D-penicillamine associated with pyridoxine for 26 patients. Adverse effects were observed in the other two patients: one presented with uncontrollable vomiting and the other demonstrated elastosis perforans serpiginosa. At the end of the study, all 26 treated patients were asymptomatic. Twenty-four of the patients were treated with D-penicillamine and pyridoxine, and two were treated with trientine and zinc sulfate. A liver transplant was performed in one patient with fulminant hepatitis, but the final patient died 48 hours after admission to the intensive care unit. CONCLUSIONS: Family screenings associated with early treatment are important in preventing Wilson's disease symptoms and potentially fatal disease progression. The study suggests that Wilson's disease must be ruled out in children older than two years presenting with abnormal levels of hepatic enzymes because of the heterogeneity of symptoms and the encouraging treatment results obtained so far.

Acquired hepatocerebral degeneration and hepatic encephalopathy: correlations and variety of clinical presentations in overt and subclinical liver disease / Degeneração hepatocerebral adquirida e encefalopatia hepática: correlações e variedade de apresentações clínicas na doença hepática evidente e subclínica

Acquired hepatocerebral degeneration (AHD) and hepatolenticular degeneration can have similar clinical presentations, but when a chronic liver disease and atypical motor findings coexist, the distinction between AHD and hepatic encephalopathy (HE) can be even more complicated. We describe three cases of AHD (two having HE) with different neuroimaging findings, distinct hepatic diseases and similar motor presentations, all presenting chronic arterial hypertension and weight loss before the disease manifestations. The diagnosis and physiopathology are commented upon and compared with previous reports. In conclusion, there are many correlations among HE, hepatolenticular degeneration and AHD, but the overlapping of AHD and HE could be more common depending on the clinical knowledge and diagnostic criteria adopted for each condition. Since AHD is not considered a priority that affects the liver transplant list, the prognosis in AHD patients remains poor, and flow interruption in portosystemic shunts must always be taken into account.

A degeneração hepatocerebral adquirida (AHD) e a degeneração hepatolenticular podem ter apresentações clínicas semelhantes, mas quando uma doença hepática crônica e achados motores atípicos coexistem, a distinção entre AHD e encefalopatia hepática (HE) pode ser ainda mais complicada. Descrevemos três casos de AHD (dois tendo HE) com diferentes achados em neuroimagem, doenças hepáticas distintas e apresentações motoras semelhantes, todos com hipertensão arterial e perda de peso antes das manifestações motoras. O diagnóstico e a fisiopatologia são comentados e comparados com relatos prévios. Concluímos que existem muitas correlações entre HE, degeneração hepatolenticular e AHD, mas a sobreposição de HE e AHD pode ser mais comum dependendo do conhecimento clínico e da acurácia dos critérios diagnósticos adotados para cada enfermidade. Como a AHD não é considerada prioridade na lista de transplante hepático, o prognóstico dos pacientes com AHD permanece ruim, e a interrupção do fluxo nos shunts portossistêmicos deve ser sempre considerada.

Doença de Wilson (degeneração hepatolenticular): revisão bibliográfica e relato de caso / Wilson’s disease (hepatolenticular degeneration): revision and case report

Este estudo faz, inicialmente, revisão dos aspectos mais atuais referentes a conceito, quadro clínico, diagnóstico e tratamento do distúrbio metabólico do cobre, definido como doença de Wilson. E relata o caso clínico de um jovem acometido de uma sequência de sintomas superpostos de origem gastrintestinal, neurológico e psiquiátrico. Pela multiplicidade e gravidade dos sintomas, teve o diagnóstico final de transtorno psicótico agudo polimórfico, com intensa inibição psicomotora. A partir de uma análise integrada dos exames já solicitados, suspeitou-se de um distúrbio metabólico de origem hereditária ou adquirida que justificasse simultaneamente os sintomas. O distúrbio da excreção do cobre, doença de Wilson, veio justificar toda a sintomatologia referida e foi confirmado a partir da dosagem sanguínea baixa de ceruloplasmina e da presença dos anéis de Kaiser-Fleischer na córnea do paciente.

It will be initially revised by the authors the most actual aspects of the concept, clinical situation, diagnosis and treatment concerning to a metabolic disturbance of the copper, Wilson?s disease. Afterwards it will be described the clinical case of a young man attacked of a sequence of superposed symptoms of gastrintestinal, neurological and psychiatric origin. For the multiplicity and gravity of the symptoms acute polimórfico with intense psicomotora inhibition had the final diagnosis of "psychotic Upheaval". Starting from an integrated analysis of the exams, it was suspected about a metabolic disturbance of hereditary or acquired origin that justify all the symptoms simultaneously. The disturbance of the excretion of copper, Wilson's disease, came to justify all the referred symptomatology and it was confirmed by the decrease sanguine dosage of ceruloplasmin, the presence of rings of Kayser-Fleischer in the córnea of the patient and of neurological lesion at the magnetic nuclear ressonance. The diagnosis of Wilson's disease in patients with simultaneous digestive (hepática cirrhosis), neurological and inexplicable psychiatric disturbances will always have to be faneed because the precocious treatment will mainly prevent serious and permanent organic damages for the liver and brain. The specific treatment was initiated and the maintenance of exactly has provoked significant improvements and a gradual new outbreak of the symptoms reintegrating the patient the family and the society.

Doença de Wilson em crianças e adolescentes: diagnóstico e tratamento / Wilson's disease in children and adolescents: diagnosis and treatment

OBJETIVO: Descrever as formas de apresentação, as alterações laboratoriais ao diagnóstico e o tratamento de crianças e adolescentes com doença de Wilson. MÉTODOS: Estudo descritivo e retrospectivo de 17 crianças e adolescentes com doença de Wilson atendidos no Ambulatório de Hepatologia Pediátrica do Hospital das Clínicas da Universidade Federal de Minas Gerais no período de 1985 a 2008. Os dados foram coletados dos prontuários e durante as consultas ambulatoriais. RESULTADOS: A idade ao diagnóstico variou de 2,8 a 15,1 anos, com média de 8,8±0,9 anos. A forma de apresentação predominante foi hepática (53 por cento), seguida por assintomáticos provenientes de triagem familiar. O anel de Kayser-Fleischer foi encontrado em 41 por cento dos pacientes. A ceruloplasmina encontrava-se alterada em 15/17 pacientes e o cobre urinário variou de 24 a 1000mcg/24h (mediana: 184mcg/24h). O tratamento instituído foi a D-penicilamina. Observaram-se efeitos colaterais em cinco crianças, sem necessidade de interrupção ou troca da medicação. As respostas clínica e laboratorial, com níveis normais de aminotransferases, foram evidenciadas em 14 pacientes após mediana de 10,7 meses de tratamento. Três crianças morreram (uma por hepatite fulminante e duas com complicações da insuficiência hepática grave), apesar do tratamento. CONCLUSÕES: A doença de Wilson é rara na faixa etária pediátrica. A forma de apresentação predominante é a hepática. Seu diagnóstico se baseia principalmente em dosagem de ceruloplasmina baixa, cobre livre e cobre em urina de 24 horas elevados, mas exige alto grau de suspeição. Apresenta boa resposta e tolerância ao tratamento medicamentoso.

OBJECTIVE: To describe clinical symptoms, laboratory findings at diagnosis and treatment of children and adolescents with Wilson's disease. METHODS: This is a descriptive and retrospective study of a series of 17 children and adolescents with Wilson's disease, assited at the Pediatric Hepatology Ambulatory of the Hospital das Clínicas of Universidade Federal de Minas Gerais, Brazil, from 1985 to 2008. Data were collected by revision of medical charts and during clinical follow-up. RESULTS: Patients were 2.8 to 15.1 years old, with a mean age of 8.8±0.9 years. The disease main presentation was hepatic (53 percent), followed by the asymptomatic form, diagnosed by family screening. The Kayser-Fleischer ring was observed in 41 percent of the patients. The ceruloplasmin was altered in 15 out of 17 patients, and the urinary copper varied from 24 to 1000mcg/24h (median: 184mcg/24h). The treatment was stablished with D-penicillamine in all cases. Slight side effects were observed in five children, with no need to interrupt or change medication. Clinical and laboratory responses to treatment, with normalization of aminotransferases levels, were shown in 14 patients after a median of 10.7 months. Although treated, three patients died (one due to fulminant hepatitis and two due to severe hepatic failure). CONCLUSIONS: Wilson's disease is rare in the pediatric group. In children, the main presentation is the liver disease. The diagnosis can be established by reduced ceruloplasmin levels and elevated copper excretion in the 24-hour urine, but it demands high suspicion level. There are good tolerance and response to medical treatment.

Doença de Wilson em crianças e adolescentes: como fazer diagnóstico precoce / Wilson's disease in children and adolescent: a key to an early diagnosis

A doença de Wilson é uma desordem autossômica recessiva do metabolismo do cobre, que leva à impregnação desse metal em diversos tecidos como o fígado, cérebro, córnea e rins. Tem prevalência de 1:40.000 e evolui de forma progressiva e fatal se não tratada. Seu diagnóstico depende de suspeição clínica e exames laboratoriais, podendo ser difícil nos pacientes assintomáticos ou com insuficiência hepática grave. A tríade clássica de apresentação é hepática, neurológica e oftalmológica. Na criança, a forma de apresentação mais comum é a hepática (aguda ou crônica). Os critérios diagnósticos são baseados na presença de ceruloplasmina baixa, cobre em urina de 24 horas e cobre livre elevados e avaliação oftalmológica à procura do anel de Kayser-Fleischer. O tratamento medicamentoso deve ser instituído o quanto antes, de forma a evitaremse as lesões teciduais do excesso de cobre, daí a grande importância do diagnóstico precoce. A droga de escolha é a D-penicilamina, mas é necessário o monitoramento de seus possíveis efeitos colaterais e eventuais pioras do quadro neuropsiquiátrico. Existem outras drogas, como a trientina, tetratiomolibdato e o zinco, que também têm efeito na redução do cobre orgânico. (AU)

Wilson disease is an authossomal recessive disorder of copper metabolism that leads to the impregnation of the metal in different tissues such as the liver, brain, cornea and kidneys. There is a prevalence of 1:40,000 and evolution is progressive and fatal if untreated. The diagnosis depends on clinical suspicion and laboratory tests, and may be difficult in situations such as the asymptomatic patients or with severe liver insufficiency. The classic triad presentation is the hepatic, neurological and ophthalmologic disease. In children, the most common is the hepatic (acute or chronic). The diagnosis criteria are based on the presence of low ceruloplasmine, elevated copper in 24-hour urine and high seric copper and ophthalmologic evaluation in search of Kayser Fleischer ring. The medication treatment must be established as soon as possible so as to prevent tissue lesions due to copper excess, hence the great importance of early diagnosis. The drug choice is the D-penicilamin, with careful monitoring of side effects and attention for occasional worsening of the neuropsychiatric state. There are other drugs as trientine, tetratiomolibdato and zinc that also have an effect on the reduction of organic copper. (AU)

Neurological and other manifestations of Wilson disease; 1998-2005

Wilson disease [WD] is an inherited copper metabolism dysfunction disease characterized by cirrhosis and CNS findings. Wilson disease is important because it is fatal not recognized and treated. Our Goa of study is to investigate the clinical signs and symptoms, lab results and other relevant matters in our patients in order to obtain a better understanding of this potentially lethal disease in our country. We have evaluated 21 cases of children with Wilson disease who were referred to Loghman and Imam Hussein Hospital between years 1998-2005. The mean age of our patients was 9 years. The presenting symptom was ascites and extremity edema in 6[28.5%] patients, behavioral changes or neurological signs in 5[24%] simultaneous Ascites and icter in 9[43%] patients and in one patient the presenting manifestation was hemolytic anemia [4.8%]. One of our patients died because of fulminant hepatitis in the course of admission [4.8%]. We showed in this study that Wilson disease can be presented by a manifold symptom in children and adolescence. Having a good concept of these symptoms in high clinical suspicious are required to diagnose this potentially lethal disease at the proper time in order to decrease the potential adverse effects of the disease especially the neuropsychiatric damages significantly

Clinicopathologic findings in 35 children with Wilson disease

Wilson disease is a rare autosomal recessive disorder of copper metabolism. Wilson disease is the most common metabolic cause of fulminant hepatic failure in children over the age years. The aim of this study was to find the major clinical and pathologic findings of Wilson disease in children in Tehran. This retrospective study was carried out in the Mofid children's hospital. Thirty five patients suffering from Wilson disease were studied. Ceruloplasmin level below 20 mg/dl and urinary copper excretion level above 100 micro g/24hr were considered as the inclusion criteria. Of the patients, 20 cases were males and 15 were females with average age of 9 years. The most patients were in 8-9 and 10-11 years age group with 37% and 20%, respectively. Hepatic invoIvement was confirmed in 100% of patients. Jaundice was seen in 20 patients [57%], abdominal enlargement together in 20 patients [57%], and encephalopathy in 9 patients [26%]. Serum copper was reduced in 100% and low-serum ceroluplasmin in 100%, increased urinary copper excretion in%97, increased AST and ALT in 100%, increased PT was in 94% patients, anemia was found in 100%, leucopenia in 14%, and thrombocytopenia was seen in 71% of patients. In this study, 37% of patients had neurological symptoms such as tremor, ataxia, difficulty in speech and delayed education. 32 patients had undergone ophthalmic examination and 62% showed KF ring in their ophtalmoscopy. According to this study, hepatic and neurologic involvement is the most consistent finding in the Wilson disease. Most patient were in the age's group of 8-9 and 10-11

[Wilson's disease in children - about 21 cases]

Wilson's disease is a familial affection, described the first time in 1912, which has an autosomic recessive transmission. It is characterized by an association of hepatic cirrhosis and neurologic manifestations caused by tissular accumulation of copper. To show clinical, genetic, diagnostic, therapeutic particularities and outcomes of this disease, we carried out a retrospective study concerning three pediatric departments in the Center of Tunisia [Kairouan, Farhat Hached and Sahloul hospitals]. We have collected 21 cases during a period of 17 years [from January 1983 to december 2000]. The finding's age of the disease ranges from 5 to 13 years [mean age 8 years and 9 months]. The sex ratio is 1,1. Consanguinity is found in 90% of cases. Finding circumstances are dominated by edematous and ascitic syndrome [28%] and by hepatomegaly [57.14%] a jaundice [19,5%], a pallor [9.52] and neurologic disorders [19% of cases]. A hepatic cytolysis was found in 38% and a decrease of prothrombin rate in 61% of cases. The ceruloplasmin concentration is lower than 200 mg/1 in 80% and a decrease in the blood rate of copper in 75% of cases. The urinary rate of copper was measured only in 9 patients; it was increased in 8 cases. The therapy consisted in D penicillamin in the first line. Outcome was marked by 3 cases of death. 18 patients are followed up and they are treated by D penicilamin

Doença de Wilson: diagnóstico clínico e sinais das "faces do panda" à ressonância magnética. Relato de caso / Wilson's disease: clinical diagnosis and \"faces of panda\" signs in magnetic resonance imaging. Case report

Homem de 25 anos de idade foi internado com sintomatologia polimorfa típica das afecções dos gânglios da base, associada a manifestações psiquiátricas. Fez uso de periciazina; no entanto, a suspensão do medicamento não melhorou a sintomatologia. Foi estabelecido o diagnóstico de doença de Wilson pela visualização do anel de Kayser-Fleischer através de exame com lâmpada de fenda e pelos exames laboratoriais que mostraram diminuição da ceruloplasmina plasmática e aumento de excreção de cobre urinário. A ressonância magnética, ponderada em T2, em cortes axiais do mesencéfalo e ponte, evidenciou imagens das "faces do panda".

Neurologic deterioration in a child with Wilson's disease on penicillamine therapy.

Penicillamine is the standard therapy for Wilson's disease in children. We report an 8-year-old-girl with liver disease due to Wilson's disease who developed extrapyramidal symptoms following administration of penicillamine. Symptoms resolved within 20 hours of stopping the drug but recurred within 24 hours when gradually increasing small doses were recommenced.
