J Inherit Metab Dis 2021; 44:1099-1112. [PMID: 34286869 DOI: 10.1002/jimd.12418] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/05/2021] [Revised: 07/12/2021] [Accepted: 07/14/2021] [Indexed: 11/07/2022]
Abstract
Wilson disease (WD) is a rare genetic condition that results from a build-up of copper in the body. It requires life-long treatment and is mainly characterized by hepatic and neurological features. Copper accumulation has been reported to be related to the occurrence of heart disease, although little is known regarding this association. We have conducted a systematic review of the literature to document the association between WD and cardiac involvement. Thirty-two articles were retained. We also described three cases of sudden death. Cardiac manifestations in WD include cardiomyopathy (mainly left ventricular (LV) remodeling, hypertrophy, and LV diastolic dysfunction, and less frequently LV systolic dysfunction), increased levels of troponin, and/or brain natriuretic peptide, electrocardiogram (ECG) abnormalities, and rhythm or conduction abnormalities, which can be life-threatening. Dysautonomia has also been reported. The mechanism of cardiac damage in WD has not been elucidated. It may be the result of copper accumulation in the heart, and/or it could be due to a toxic effect of copper, resulting in the release of free oxygen radicals. Patients with signs and/or symptoms of cardiac involvement or who have cardiovascular risk factors should be examined by a cardiologist in addition to being assessed by their interdisciplinary treating team. Furthermore, ECG, cardiac biomarkers, echocardiography, and 24-hours or more of Holter monitoring at the diagnosis and/or during the follow-up of patients with WD need to be evaluated. Cardiac magnetic resonance imaging, although not always available, could also be a useful diagnostic tool, allowing assessment of the risk of ventricular arrhythmias and further guidance of the cardiac workup.

Abstract
Copper (Cu) is an essential micronutrient required for the activity of redox-active enzymes involved in critical metabolic reactions, signaling pathways, and biological functions. Transporters and chaperones control Cu ion levels and bioavailability to ensure proper subcellular and systemic Cu distribution. Intensive research has focused on understanding how mammalian cells maintain Cu homeostasis, and how molecular signals coordinate Cu acquisition and storage within organs. In humans, mutations of genes that regulate Cu homeostasis or facilitate interactions with Cu ions lead to numerous pathologic conditions. Malfunctions of the Cu+ -transporting ATPases ATP7A and ATP7B cause Menkes disease and Wilson disease, respectively. Additionally, defects in the mitochondrial and cellular distributions and homeostasis of Cu lead to severe neurodegenerative conditions, mitochondrial myopathies, and metabolic diseases. Cu has a dual nature in carcinogenesis as a promotor of tumor growth and an inducer of redox stress in cancer cells. Cu also plays role in cancer treatment as a component of drugs and a regulator of drug sensitivity and uptake. In this review, we provide an overview of the current knowledge of Cu metabolism and transport and its relation to various human pathologies.

Abstract
Background Several conditions represented mainly by movement disorders are associated with cardiac disease, which can be overlooked in clinical practice in the context of a prominent primary neurological disorder. Objectives To review neurological conditions that combine movement disorders and primary cardiac involvement. Methods A comprehensive and structured literature search following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses criteria was conducted to identify disorders combining movement disorders and cardiac disease. Results Some movement disorders are commonly or prominently associated with cardiac disease. Neurological and cardiac symptoms may share underlying physiopathological mechanisms in diseases, such as Friedreich's ataxia and Wilson's disease, and in certain metabolic disorders, including Refsum disease, Gaucher disease, a congenital disorder of glycosylation, or cerebrotendinous xanthomatosis. In certain conditions, such as Sydenham's chorea or dilated cardiomyopathy with ataxia syndrome (ATX-DNAJC19), heart involvement can present early in the course of disease, whereas in others such as Friedreich's ataxia or Refsum disease, cardiac symptoms tend to present in later stages. In another 68 acquired or inherited conditions, cardiac involvement or movement disorders are seldom reported. Conclusions As cardiac disease is part of the phenotypic spectrum of several movement disorders, heart involvement should be carefully investigated and increased awareness of this association encouraged as it may represent a leading cause of morbidity and mortality.

Abstract
PURPOSE Although the hepatic and neurological consequences of Wilson's disease (WD) have been investigated in detail, its cardiac involvement remains little studied. Our aim was to investigate potential cardiac differences in strain (ST) and strain rate (STR) echocardiography in adult WD patients compared with controls. METHODS We included 30 patients with WD and a control group of 26 sex and age matched healthy adults. None of the subjects in either group had cardiac complaint. WD patients were clinically evaluated by a neurologist and undergone cranial magnetic resonance imaging. They were then divided into two groups according to the presence (NW) or absence (non-NW) of neurological involvement. Standard and advanced speckle tracking echocardiographic evaluations were performed in each group according to guidelines. RESULTS Left ventricular (LV) systolic and diastolic diameters and wall thickness measurements were within normal limits and did not differ significantly between the groups (P > .05). Neither atrial peak longitudinal and circumferential ST variables nor LV global and longitudinal ST and STR variables showed significant differences between the NW, the non-NW, and the control group (P > .05). CONCLUSION Our echocardiographic study showed no detectable difference between adult WD patients with or without neurological involvement and healthy subjects.

Abstract
BACKGROUND This study evaluated cardiac function using tissue Doppler echocardiography and assessed electrocardiographic findings in children diagnosed with Wilson's disease. METHOD Asymptomatic patients with a diagnosis of Wilson's disease (n = 43) were compared to healthy controls (n = 37) that were age and gender matched. RESULTS The standard electrocardiographic and conventional echocardiographic examinations were similar in both groups. The left ventricular ejection fraction, shortening fraction, and diastolic function were not significantly different between the two groups. The Tei index for mitral lateral, mitral septal, tricuspid lateral, tricuspid septal, and inter-ventricular septum on tissue Doppler echocardiography was higher in the patient group, yet it did not reach statistical significance. Mitral lateral and septal systolic annular velocity values were significantly lower in the patient group when compared to the control group (p = 0.02 and 0.04, respectively). Also, mitral lateral and septal isovolumetric contraction time values were higher in the patient group (p = 0.04). Although the left ventricular values were not significantly different, relative left ventricular wall thickness was higher in the patient group when compared to the control group, and concentric remodelling in the left ventricle was found in 7 (16%) of 42 patients. QT interval (p = 0.02) and P-wave dispersion values (p = 0.04) were significantly higher in the patient group compared to the control group, and these tend to predict arrhythmias. CONCLUSION Our study based on the tissue Doppler echocardiography assessment indicated a subclinical systolic, rather than diastolic, dysfunction in the myocardium with increased QT interval and P-wave dispersion, despite the young age of the patients and short disease duration.

Abstract
INTRODUCTION Wilson's disease (WD) is a rare genetic disorder that leads to impairments in copper metabolism. Patients principally exhibit liver and neuropsychiatric symptoms, but because copper also accumulates in all body organs, other (typically milder) clinical symptoms can occur. To date, cardiac involvement has not been thoroughly investigated in patients with WD. This study aimed to evaluate heart structure and function in patients with WD with commonly available diagnostic methods. MATERIAL AND METHODS We compared 125 WD patients with an age- and sex-matched control group. Patients with WD were grouped according to their dominant symptoms - neurologic or hepatic. All subjects underwent clinical, electrocardiographic (ECG), and echocardiographic examinations. RESULTS All subjects had sinus rhythm on electrocardiography. The only ECG parameter that differed between patients with WD and the control group was the QRS prolongation (92.0 vs. 86.4 ms; p < 0.05). On echocardiography patients with WD exhibited more hypertrophy in the left ventricle than controls (posterior wall in diastole: 1.0 vs. 0.93; p < 0.01) and the left ventricle hypertrophy was more pronounced in the neurologic than in the hepatic subgroup (1.05 vs. 0.96 cm; p < 0.01). Left ventricular systolic function was similar in the WD and the control group (ejection fraction: 67.5% vs. 67.7%). On tissue Doppler echocardiography patients with WD demonstrated slowing of myocardial relaxation, which was more evident in the neurologic group. CONCLUSIONS Heart involvement in WD was manifested mainly by mild left ventricular hypertrophy and subclinical changes in diastolic function, particularly in the patients with the neurologic form of disease.

Abstract
BACKGROUND Clinical presentations of Wilson's disease (WD) in childhood ranges from asymptomatic liver disease to cirrhosis or acute liver failure, whereas neurological and psychiatric symptoms are rare. The basic diagnostic approach includes serum ceruloplasmin and 24-hour urinary copper excretion. Final diagnosis of WD can be established using a diagnostic scoring system based on symptoms, biochemical tests assessing copper metabolism, and molecular analysis of mutations in the ATP7B gene. Pharmacological treatment is life-long and aims at removal of copper excess by chelating agents as D-penicillamine, trientine, or inhibition of intestinal copper absorption with zinc salts. Acute liver failure often requires liver transplantation. This publication aims to provide recommendations for diagnosis, treatment, and follow-up of WD in children. METHODS Questions addressing the diagnosis, treatment, and follow-up of WD in children were formulated by a core group of ESPGHAN members. A systematic literature search on WD using MEDLINE, EMBASE, Cochrane Database from 1990 to 2016 was performed focusing on prospective and retrospective studies in children. Quality of evidence was assessed according to the GRADE system. Expert opinion supported recommendations where the evidence was regarded as weak. The ESPGHAN core group and ESPGHAN Hepatology Committee members voted on each recommendation, using the nominal voting technique.

Abstract
In their clinical practice, physicians can face heart diseases (chronic or acute heart failure) affecting the liver and liver diseases affecting the heart. Systemic diseases can also affect both heart and liver. Therefore, it is crucial in clinical practice to identify complex interactions between heart and liver, in order to provide the best treatment for both. In this review, we sought to summarize principal evidence explaining the mechanisms and supporting the existence of this complicate cross-talk between heart and liver. Hepatic involvement after heart failure, its pathophysiology, clinical presentation (congestive and ischemic hepatopathy), laboratory and echocardiographic prognostic markers are discussed; likewise, hepatic diseases influencing cardiac function (cirrhotic cardiomyopathy). Several clinical conditions (congenital, metabolic and infectious causes) possibly affecting simultaneously liver and heart have been also discussed. Cardiovascular drug therapy may present important side effects on the liver and hepato-biliary drug therapy on heart and vessels; post-transplantation immunosuppressive drugs may show reciprocal cardio-hepatotoxicity. A heart-liver axis is drafted by inflammatory reactants from the heart and the liver, and liver acts a source of energy substrates for the heart.

Abstract
Wilson's disease is a well-characterized disorder known to cause liver and brain disease due to abnormal copper deposition. Data regarding copper infiltration of the heart is conflicting, and the risk of heart disease has not been well described. We aimed to determine whether Wilson's disease is associated with cardiac myopathy, clinically evident in the atria as atrial fibrillation (AF) and in the ventricles as heart failure (HF). We longitudinally assessed 14.3 million patients in the California Healthcare Cost and Utilization Project database from 2005 through 2009 for diagnoses of Wilson's disease, AF, HF, and covariates using International Classification of Diseases-9th Edition codes. Cirrhosis and appendicitis diagnoses were assessed for positive and negative validation, respectively. We identified 463 patients with Wilson's disease. As expected in validation analyses, patients with Wilson's disease had a threefold greater risk of cirrhosis (hazard ratio [HR] 2.85, 95% confidence interval [CI] 2.81 to 2.90, p <0.0001) and no increased risk of appendicitis (HR 0.24, 95% CI 0.04 to 1.71, p = 0.16). Patients with Wilson's disease exhibited a 29% higher risk of AF after adjusting for age, gender, race, income, hypertension, diabetes, renal disease, hyperlipidemia, obesity, coronary disease, and obstructive sleep apnea (HR 1.29, 95% CI 1.15 to 1.45, p <0.0001). After adjusting for the same covariates, patients with Wilson's disease had a 55% higher risk of incident HF (HR 1.55, 95% CI 1.41 to 1.71, p <0.0001). Patients with Wilson's disease have an increased risk of AF and HF, supporting the need for careful surveillance for heart disease. These findings also suggest that the role of copper metabolism in heart disease should be more broadly investigated.

Abstract
Wilson disease (WD) is an inherited disorder mainly of hepatocellular copper disposition, due to dysfunction of the Wilson ATPase, a P1B-ATPase encoded by the gene ATP7B. In children, as in older age brackets, clinical disease is highly diverse. Although hepatic disease is the common presentation in children/adolescents, neurologic, psychiatric, and hematologic clinical presentations do occur. Very young children may have clinically evident liver disease due to WD. Early diagnosis, preferably when the child/adolescent is asymptomatic, is most likely to result in near-normal longevity with generally good health so long as the patient tolerates effective medication, is adherent to the lifelong treatment regimen, and has consistent access to the medication. Apart from a lively index of clinical suspicion on the part of physicians, biochemical tests including liver tests, serum ceruloplasmin, and basal 24-hour urinary copper excretion and genotype determination are key to diagnosis. Oral chelation treatment remains central to medical management, although zinc appears to be an attractive option for the presymptomatic child. Pediatric patients presenting with Wilsonian fulminant hepatic failure must be differentiated from those with decompensated cirrhosis, since the latter may respond to intensive medical interventions and not require liver transplantation. Recently identified WD-mimic disorders reveal important aspects of WD pathogenesis.

Abstract
Wilson disease (WD) is a rare disorder of copper metabolism that presents mainly with hepatic and neuropsychiatric features. Copper accumulates not only in the liver and brain, but also in other organs. Liver injury can also be the cause of secondary impairment of other tissues. Therefore, the clinical manifestation of WD may be renal, cardiac, skin, osteoarticular, or endocrinologic and include other organ disturbances. Renal abnormalities include tubular dysfunction (e.g., renal tubular acidosis, aminoaciduria) and nephrolithiasis. Bone demineralization is a common manifestation in patients with WD. Cardiac injury may include arrhythmia, cardiomyopathy, and autonomic dysfunction. Different endocrine system manifestations, such as infertility or repeated miscarriages, growth and puberty disturbances, and hypoparathyroidism, are observed. Other important clinical aspects of WD include pancreas involvement, immunologic abnormalities, the presence of lipomas, and skin changes. Although other organ involvement is not common in WD and usually not severe, delayed diagnosis may lead to irreversible changes in organs and tissues. Therefore, awareness of other possible WD presentations is important in the differential diagnosis of WD.

Abstract
OBJECTIVE This study aimed to evaluate strain and strain rate echocardiography in children with Wilson's disease to detect early cardiac dysfunction. METHODS In this study, 21 patients with Wilson's disease and a control group of 20 age- and gender-matched healthy children were included. All the patients and the control group were evaluated with two-dimensional (2D) and colour-coded conventional transthoracic echocardiography by the same paediatric cardiologist using the same echocardiography machine (Vivid E9, GE Healthcare, Norway) in standard precordial positions, according to the American Society of Echocardiography recommendations. 2D strain and strain rate echocardiography were performed after the ECG probes of the echocardiography machine were adjusted for ECG monitoring. Longitudinal, transverse and radial strain, and strain rate were assessed from six basal and six mid-ventricular segments of the left ventricle, as recommended by the American Society of Echocardiography. RESULTS Left ventricular wall thickness, systolic and diastolic diameters, left ventricular diameters normalised to body surface area, end-systolic and end-diastolic volumes, cardiac output and cardiac index values were within normal limits and statistically similar in the patient and control groups (p > 0.05). Global strain and strain rate: the patient group had a statistically significant lower peak A longitudinal velocity of the left basal point and peak E longitudinal velocity of the left basal (VAbasR) point, and higher global peak A longitudinal/circumferential strain rate (GSRa) compared to the corresponding values of the control group (p < 0.05). Radial strain and strain rate: end-systolic rotation [ROT (ES)] was statistically significantly lower in the patient group (p < 0.05). Longitudinal strain and strain rate: end-systolic longitudinal strain [SLSC (ES)] and positive peak transverse strain (STSR peak P) were statistically significantly lower in the patient group (p < 0.05). Segmental analysis showed that rotational strain measurement of the anterior and lateral segments of the patient group were statistically significantly lower than the corresponding values of the control group (p < 0.05). Segmental analysis showed statistically significantly lower values of endsystolic longitudinal strain [STSR (ES)] of the basal lateral (p < 0.05) and end-systolic longitudinal strain [SLSC (ES)] of the basal septal segment (p < 0.05) in the patient group. End-systolic longitudinal strain [SLSC (ES)] and positive peak transverse strain (STSR peak P) were statistically significantly lower in the patient group (p < 0.05). Segmental analysis showed statistically significantly lower values of endsystolic longitudinal strain [SLSC (ES)] of the mid-anterior and basal anterior segments (p < 0.05), end-systolic longitudinal strain [STSR (ES)] measurements of the posterior and mid-posterior segments, end-systolic longitudinal displacement [DLDC (ES)] of the basal posterior, mid-posterior and mid-antero-septal segments in the patient group. CONCLUSION Cardiac arrhythmias, cardiomyopathy and sudden cardiac death are rare complications but may be seen in children with Wilson's disease due to copper accumulation in the heart tissue. Strain and strain rate echocardiography is a relatively new and useful echocardiographic technique to evaluate cardiac function and cardiac deformation abnormalities. Our study showed that despite normal systolic function, patients with Wilson's disease showed diastolic dysfunction and regional deformation abnormalities, especially rotational strain and strain rate abnormalities.

PATIENTS AND METHODS A total of 32 diabetic and 18 healthy children were enrolled. Spectral Doppler analysis and tissue Doppler measurements were performed by conventional echocardiography. The 24-h ambulatory BP and serum BNP levels were measured. RESULTS Analysis of ambulatory blood pressure monitoring (ABPM) recordings showed that median daytime diastolic BP load were significantly higher in diabetic patients compared to controls [12.35 (4.23-27.23) vs. 2.5 (0-8.7), p = 0.007]. Patients with elevated daytime systolic and diastolic BP loads had significantly higher BNP values compared to patients with normal BP load (31.4 ± 24.36 vs. 11.84 ± 11.25 pg/mL, p = 0.03 and 23.21 ± 15.12 vs. 12.12 ± 14.65 pg/mL, p = 0.03, respectively). Isovolemic contraction time (47.43 ± 7.84 vs. 42.27 ± 7.47, p = 0.045), isovolemic relaxation time (68.84 ± 10.43 vs. 58.77 ± 10.02, p = 0.02), and myocardial performance index (0.45 ± 0.10 vs. 0.37 ± 0.09, p = 0.02) as determined by tissue Doppler echocardiography were significantly high in diabetic patients compared to that of control cases. Ratio of mitral peak early diastolic flow velocity (E) to peak early diastolic myocardial velocities by tissue Doppler echocardiography (E') was also higher in patients with elevated daytime systolic BP load (E/E', 6.71 ± 1.97 vs. 4.91 ± 1.02, p = 0.04). CONCLUSION Elevated BP loads detected by 24-h ambulatory BP measurements in children with type 1 diabetes are associated with increased BNP levels and abnormal tissue Doppler echocardiography indices, indicating early stage cardiac dysfunction.
