INITIAL ASSESSMENT FINDINGS IN PATIENTS WITH CONFIRMED WILSON’S DISEASE

Bacground. The optimization of Wilson’s disease (WD) diagnosis is one of the most disputable problem. Objective. The retrospective study of initial assessment findings under clinical suspicion for WD in 102 patients with the confirmed diagnosis. Material and methods. The results of laboratory tests and Kaiser-Fleischer rings (KF rings) identification under clinical suspicion for WD in 102 patients with the confirmed diagnosis. Results. At stage I, 17 patients (16.7%; 95% CI 10.7–25.1) were defined as having clinically definitive WD based on the combination of low serum ceruloplasmin and KF rings, 4 patients (3.9%; 95% CI 1.5–9.7) – based on the drop of ceruloplasmin level. After stage II, involving 24-hour urinary copper excretion evaluation, the rate of definitive diagnosis of WD reached 24,5% (95% CI 17.2 33.7). After stage III (genotyping for carriage of ATP7B gene mutations) – 56.9% (95% CI 47.2–66.0). Serum free copper increase was found in 54.9% (95% CI 41.4 67.7) of cases. Conclusions. Under clinical suspicion for WD, initial structured ophthalmological, laboratory and molecular-genetic assessment ensured the diagnosis of WD only in 56.9% (95% CI 56.9; 47.2–66.1). Frequent detection of serum free copper increase (54.9%, 95% CI 41.4 67.7) allows to use this test due to its greater availability as compared with 24-hour urinary copper excretion evaluation in WD diagnostics.

Correlation Factors and a Predictive Model of Serum Ceruloplasmin Normalized Wilson’s Disease

Background: The false increase of ceruloplasmin (Cp) in some Wilson’s disease (WD) patients, which overlaps with those in non-WD liver disease patients, decrease the diagnostic accuracy. The aims of our study was to understand the factors affecting WD patients’ Cp normalization, and develop a model using routine predictors to identify WD patients with ambiguous serum Cp.Results: The mixed effects model analysis which executed in longitudinal study revealed that the WD patients’ Cp normalization were significantly associated with the copper burden and liver function indexes, like urinary copper treated with dimercaptopropansulfonate sodium (P=0.000), aspartate aminotransferase (P=0.011), γ-glutamyltransferase (P=0.000), albumin (P=0.000). Multivariate logistic regression analysis in case-control study showed age (P=0.000) and serum creatine (P=0.000) were independent risk factors associated with WD. Based on their regression coefficients, a simplified WD index was derived: 0.001 × age [yr] × Creatine [umol/L]. The AUC value of WD index in total cohort were 0.923 (P=0.000). At a WD index cutoff value of ≤ 1.9 and ≤ 2.5, the positive and negtive predictive value are 88.2% and 89.9% for WD, respectively.Conclusions: The increase of serum Cp in WD patients is related to their excessive copper burden and hepatic injury, common tests can effectively foretell those WD patients with nearly normal serum Cp from other liver injury patients.

FOUR DIFFERENT PRESENTATIONS OF WILSON’S DISEASE IN ONE FAMILY

Wilson’s disease (WD) is an important differential to consider in any child presenting with hepatic, neurological or ophthalmological manifestations of the disease. We report here 4 individuals of the same family: 2 paediatric and 2 adult patients with a spectrum of manifestations of the disease presenting to Pak Emirates Military Hospital and Combined Military Hospital Rawalpindi, Rawalpindi, from January 2019 and September 2020. The index case had neuro-wilson; the brother was diagnosed preemptively during screening; the father being completely asymptomatic despite markedly raised 24 hours urinary copper levels; and the paternal uncle being diagnosed after many years of manifesting hepatic symptoms. The purpose of this publication is to sensitize the readers to the usage of scoring tools such as the Leipzig score, the importance of regular follow-up and family screening of hereditary diseases. We would also like to highlight the possibility of missed diagnosis with serum Copper levels (S.Copper) which were within normal limits (WNL) in all 4 of our patients; and Serumceruloplasmin (S.ceruloplasmin) levels which were within normal limits in 3\4 of these patients, that are often used as screening tools for WD.

Recurrent acute pancreatitis in a Wilson disease patient: an unusual association

Background Wilson’s disease is a multisystem disorder with predominant clinical symptoms depending on the site of copper deposition in the body. Hepatic presentation is usually seen in the younger age group. And pancreatitis is rarely associated with Wilson’s disease. To the best of our knowledge, recurrent acute pancreatitis as a presenting manifestation in a WD patient has not been mentioned before in the literature. Case presentation We report a 17-year-old boy who presented with recurrent acute pancreatitis and subsequently developed deranged liver enzymes and ascites. Work up for the cause of recurrent acute pancreatitis was normal. Low ceruloplasmin (0.07 mg/dL), high 24-h urinary copper excretion (576 μg/day), and dry copper content in the liver (270 μg/g) clinched the diagnosis of Wilson’s disease. The patient was started on a low-copper diet and D-penicillamine therapy resulting in an improvement in symptoms and no further recurrence of pancreatitis. Conclusion The possibility of Wilson’s disease should be considered in young patients with recurrent acute pancreatitis, who have a protracted and obscure disease course.

Cognitive Impairment In Stable Wilson Disease Across Phenotype.

Background: In Wilson disease (WD), mutations in the gene encoding the ATP7B copper transport protein causes accumulation of copper especially in liver and brain. WD typically presents with hepatic and/or neuropsychiatric symptoms. Impaired cognition is a well-described feature in patients neurological WD, while the reports on cognition in hepatic WD patients are fewer and less conclusive. We examined cognition in a cohort of WD patients with both phenotypes. Methods: In this cross-sectional pilot study, we investigated cognition in 28 stable Danish WD patients by portosystemic encephalopathy (PSE) and continuous reaction time (CRT) tests. Half of the patients were female and median age was 35.5 years (IQR 24.5). The phenotype was hepatic in 14 (50%), neurologic in 10 (36%) and mixed in 4 4 (14%). The duration of treatment was >2 year in all patients, and the condition stable as judged by urinary copper excretion, liver enzymes, and clinical assessment.Results: In total, 16 (57%) patients performed worse than normal in the PSE and/or CRT tests. The two tests correlated (rho=0.60, p=0.0007) with each other, but neither correlated with phenotype, MELD-, Child-Pugh score, 24h-U-Cu, or treatment type.Conclusion: Measurable cognitive impairment was present in more than half of the stable WD patients independent of phenotype. Thus, our data questions the existence of a purely hepatic phenotype.

Wilson’s Disease Presenting in Late Adult Life

Wilson’s disease (WD) is an autosomal recessive disease affecting the copper metabolism resulting in various clinical presentations. Diagnosis includes the presence of low serum copper and ceruloplasmin concentrations, increased urinary copper excretion, and/or increased hepatic copper concentrations. Yet, genetic testing remains diagnostic. Management includes copper chelating agents and liver transplant in advance cases. We report a case of WD presenting with liver function impairment in late adult life and started on treatment. Therefore, early diagnosis and treatment of WD can prevent related complications.

Value of Kayser-Fleischer ring as a diagnostic tool for Wilson’s disease in children

The Kayser-Fleischer(K-F) ring is the hallmark of Wilson’s disease (WD). In most adults or older children, the diagnosis of Wilson’s disease may be made easily when K-Frings and low ceruloplasmin levels are present. In this study presence of K-F ring has been evaluated among children with liver disease in Bangladesh to improve the management of Chronic liver disease due to WD and reduce complications. This cross-sectional study was carried out at the Department of Paediatric Gastroenterology and Nutrition, BSMMU, Dhaka on 60 children presented with liver disease. Thirty children over three years of age considered as cases (Group-I) and thirty children with non- Wilsonian liver disease as control (Group-II). Slit lamp examination for K-F ring and twenty-four hour urinary copper excretion after giving one gram d-penicillamine 12-hour apart were done in each patient. The efficacy of K-F ring was studied. Mean age of WD patients was 8.9± 2.78 years, with a male female ratio of 1.3: 1. There was significant low level of serum ceruloplasmin in 93.33% of cases (p<.001). After penicillamine challenge, 24-hour urinary copper excretion was found significantly higher in patients with WD (median 3626.5±1698 μg/24h, range 1262- 195000) than non-Wilsonian liver disease (median 450±278.09 μg/24-h, range 47- 2062 μg/24h), (p<.001). K-F ring was found in 15 (50%) patients, absent in all patients of non-Wilsonian liver disease group and the difference was statistically significant (p<.001). Evaluation of Kayser-Fleischer ring is still a very essential diagnostic tool and is a non-invasive, affordable way to assist in the diagnosis of a potentially fatal disease.

Histopathology of Wilson Disease

Wilson Disease (WD) is a genetic metabolic disease of copper metabolism. The implicated gene is ATP7B, encodes a P-type ATPase which transports copper. The resultant defective metabolism of copper results in copper accumulation in multiple tissues especially liver, eye and central nervous system. WD occurs worldwide, usually between 5 and 35 years; a wider age range is also reported. Clinical presentations are diverse and include combinations of hepatic, neurological, ophthalmic and psychiatric manifestations. Other organs or tissues may also be affected. Biochemical abnormalities such as serum ceruloplasmin and 24-h urinary copper excretion are important for the diagnosis but are not always abnormal in WD. The liver histopathology has several different patterns from mild nonspecific changes to acute fulminant hepatitis and cirrhosis. Copper histochemistry is helpful in diagnosis. Genetic testing is another diagnostic tool. It is important to diagnose WD because it is fatal when overlooked, curable when diagnosed. The diagnosis should be keep in mind at all ages in patients with hepatic disease, neurological disease, or psychiatric symptoms.
