Introduction: The liver and central nervous system are the usual targets of Wilson's disease, an inherited disorder of copper metabolism. Severe hemolytic anemia is an unusual complication of Wilson's disease.
Exegesis: We report two cases of Wilson's disease revealed by acute intravascular hemolytic anemia associated with liver failure. Blood smear analysis showed stippled red cells in one case; hemolytic anemia improved within a few weeks in both patients but progressive liver failure required transplantation in the other. Hemolysis probably results from the toxic effect of free serum copper on erythrocyte membrane.
Conclusion: Diagnosis of Wilson's disease must be considered in case of acute hemolytic anemia associated with liver failure in young adults.

Background: Wilson's disease (WD) is a rare metabolic disorder of copper accumulation in organs such as liver, brain, and cornea. Diagnoses and treatments are challenging in settings, where advanced diagnostic tests are unavailable, copper chelating agents are frequently scarce, healthcare professionals lack disease awareness, and medical follow-ups are limited. Prompt diagnoses and treatments help prevent complications, improve patients' quality of life, and ensure a normal life expectancy.

As a structural and catalytic cofactor, copper is involved in many biological pathways and is required for the biochemistry of all living organisms. However, excess intracellular copper can induce cell death due to its potential to catalyze the generation of reactive oxygen species, thus copper homeostasis is strictly regulated. And the deficiency or accumulation of intracellular copper is connected with various pathological conditions.

An intriguing aspect of restrictive cardiomyopathies (RCM) is the microbiome role in the natural history of the disease. These cardiomyopathies are often difficult to diagnose and so result in significant morbidity and mortality. The human microbiome, composed of billions of microorganisms, influences various physiological and pathological processes, including cardiovascular health.

Metabolic abnormalities associated with liver disease have a significant impact on the risk and prognosis of cholecystitis. However, the underlying mechanism remains to be elucidated. Here, we investigated this issue using Wilson's disease (WD) as a model, which is a genetic disorder characterized by impaired mitochondrial function and copper metabolism.

Background & Aim: Twenty-four-hour urinary copper excretion (24 h-UCE) is the standard diagnostic tool for dose adjustments in maintenance therapy in Wilson disease (WD) patients. Guidelines lack data if both variants of 24 h-UCE measurement (with or without 48 h of treatment interruption) are equally interpretable.
Methods: Eighty-four patients with a confirmed diagnosis of WD treated with chelators (50% of patients with D-Penicillamine and 50% with trientine) and with pairwise 24-h-UCE values on-therapy and off-therapy were included in the analysis.
