1 Introduction Provide an overview of Wilson's Disease, its significance, and prevalence. 2 Objectives Discuss the main goals and aims of improving diagnosis and treatment methods for Wilson's Disease. Agenda Key Points for Advancements in Diagnosis and Treatment of Wilson's Disease Healthcare
Copper in Ferroprotein Copper is a vital element in ferroprotein, influencing iron metabolism and melanin synthesis. Diverse Functional Roles Copper contributes to energy production, neurotransmitter synthesis, and central nervous system function . Dietary Copper Sources Key dietary sources of copper encompass shellfish , liver, nuts, legumes,beans , and organ meats . Introduction to Wilson’s Disease Unveiling the Role of Copper and Dietary Sources Copper Role & Dietary Sources
1 Definition Wilson's disease is a rare genetic disorder that leads to copper accumulation in various organs, primarily the liver and brain. 2 Pathogenesis The disease is caused by mutations in the ATP7B gene, which impairs copper transport, resulting in its toxic buildup. 3 Clinical Picture Patients may present with liver disease, neurological symptoms, psychiatric manifestations, or a combination of these. 4 Diagnostics Diagnosis involves blood tests for copper levels, genetic testing for ATP7B mutations, liver biopsy, and imaging studies. OBJECTIVES Understanding the Core Aspects of Wilson's Disease Core Concepts
ATP7B Gene Mutations Autosomal recessive mutations occur in the ATP7B gene on chromosome 13 . DEFECTIVE ATP7B Protein Mutations lead to a defective ATP7B protein, reducing copper incorporation into apoceruloplasmin. Impact on Serum Copper Levels Reduced biliary copper excretion causes elevated free serum copper, leading to its accumulation in various organs. Pathogenesis of Wilson’s Disease Understanding the Genetic Basis and Copper Metabolism Genetic Basis & Copper Metabolism
1 Jaundice Yellowing of the skin and eyes due to bilirubin build-up. 2 Hepatomegaly Enlargement of the liver beyond its normal size. 3 Edema Swelling caused by fluid retention, usually in the legs. 4 Ascites Abnormal accumulation of fluid in the abdominal cavity. 🦠 Which initially Considered of viral hepatitis and cirrhosis , and the diagnostics take place for .

Kayser -Fleischer Ring Approximately 95% of patients with neurologic signs exhibit the characteristic Kayser-Fleischer ring, contrasting with around 65% in those presenting with hepatic symptoms. Sun flower cataract Presence is not common like KfR but feature in the ocular presentation of Wilson's disease, aiding in diagnosis alongside the Kayser-Fleischer ring. Visual Impairment Visual impairment may occur due to cataracts or retinal degeneration in individuals with Wilson's disease, highlighting the impact of copper accumulation on ocular health.

Tremor or Choreiform Movements Abnormal Gait Uncoordinated Handwriting Clinical Picture: Neuro Presentation Neurological Symptoms of Wilson's Disease Symptoms Overview
Personality Changes Common symptoms are characterized by alterations in personality, such as irritability, anger outbursts, and poor self-control. 1 Depression Patients often experience symptoms of depression, which can manifest as persistent feelings of sadness, hopelessness, and loss of interest in activities. 2 Anxiety Anxiety is prevalent among individuals with Wilson's Disease and can present as excessive worry, restlessness, and feelings of tension. 3 Clinical Picture: Psychiatric Presentation Understanding Psychiatric Symptoms in Wilson's Disease Psychiatric Symptoms

Medical Diagnostics Innovations Diagnostics Advancements in Diagnostic Techniques for Wilson's Disease 1 FIRST TO ORDER LFTs 24-hours urinary copper slit- lamp examination Serum ceruloplasmin THEN YOU CAN COSIDER FBC Liver biopsy MRI brain NCC DNA test for mutation
Routine laboratory Studies Diagnostics: Biochemical/Laboratory Findings Exploring Essential Laboratory Tests for Wilson's Disease Diagnosis Diagnostic Insights Liver function test : ( AST and ALT ) Increase transaminases in 40-60% Bilirubin Elevated in approximately 12% Coobes-teast (for hemolytic anemia ) Negative coombes test Low albumin and prolonged INR In acute or chronic liver faliure
↓ Serum ceruloplasmin (< 20 mg per dl ) ↑ 24-hour urine copper excretion(>100 micrograms) Optional ↓ Total serum copper ↑ Free serum copper Diagnostics: Copper Metabolism Studies Identifying Key Diagnostic Markers for Wilson's Disease Diagnostic Markers Must be in a copper free container Useful also in follow up of chelting agents Can be increase in inflammations as in acute stage Not measured before 6 months aged child (usually low in infant )
The presence of Kayser-Fleischer rings supports the suspicion of Wilson's Disease but their absence does not rule out the diagnosis . Diagnostic significance 2 Conduct a slit-lamp examination by a skilled professional to identify Kayser-Fleischer rings accurately . Kayser-Fleischer rings examination 1 Diagnostics: Kayser-Fleischer Rings Detection and Implications Diagnostic Insights
Liver Biopsy Consider liver biopsy if initial tests yield inconclusive results. Positive copper staining observed, although sensitivity may be low . More than 250microgram per gram dry wight of tissue is consistent with Wilson Hepatic Copper Concentration Levels exceeding 250 mcg/g (dry weight) suggest the presence of Wilson disease. Genetic Testing Recommended for screening first-degree relatives of Wilson disease patients or when initial diagnostic tests are inconclusive.

Diagnostic Score Proposal As diagnostic score was suggested by the working party at the 8th Leipzig, 2001, incorporating all available tests. International Meeting on Wilson's Disease n Diagnostic Score Proposal Ceruloplasmin level is not reliable single test as well as Kyser -fleshing ring may not be present as in many hepatic dominant presentation so * Acmbination of tests is needed Diagnostics: Diagnostic Score Advancements in Diagnosis via Diagnostic Score Diagnosis Advancements

Increased Metallothionein Synthesis Zinc acetate enhances metallothionein synthesis, which reduces the absorption of dietary copper. Beneficial for Specific Patient Groups Particularly valuable for young, presymptomatic patients, pregnant patients, and for maintenance therapy. Treatment: Reduction of Copper Absorption Effectiveness of Zinc Acetate (Galzin) Therapy Therapeutic Efficacy
Advanced Stages Requirement Liver transplant is considered for advanced Wilson's disease stages that do not respond to medical treatments . Delayed Diagnosis Consequence In cases of delayed Wilson's disease diagnosis, where hepatic damage is irreversible, liver transplantation becomes necessary . Therapy Unresponsiveness When patients with Wilson's disease are unresponsive to medical therapy, liver transplantation may be the next viable option. Compliance and Hepatic Damage Poor patient compliance leading to severe hepatic damage may prompt the need for liver transplantation in Wilson's disease .

Consider Wilson's Disease Wilson’s Disease should be considered in individuals with liver abnormalities or neurological movement disorders of uncertain cause . Combined Symptoms Alert The disease must be considered in patients with unexplained liver disease combined with neurological or neuropsychiatric disorders . Diagnostic Evidence A low serum ceruloplasmin level is indicative of Wilson's Disease and should be taken as evidence for diagnosis . ( guid you for furthure evaluation ) Typical Biochemical Finding Stronge suggestive ceruloplasmin level is 5m per dL but below 20mg is low and need furthure evaluation Key Recommendations Essential Guidelines for Diagnosing Wilson's Disease Diagnostic Guidelines
Genetic Disorder Impacting Copper Metabolism Wilson’s Disease is a genetic disorder with an impact on copper metabolism within the body. Significance of Early Diagnosis and Treatment Early diagnosis and timely treatment are critical to prevent irreversible damage caused by Wilson's Disease.
