Miss Meenakshi, a 9 year old girl, 2nd order child born of a second-degree consanguineous marriage from Madurai, Tamil Nadu presented with complaints of progressive yellowish discoloration of the eyes and dark urine for 6 months, gradual abdominal distension with fullness of the flanks for 4 months, easy bruising and recurrent nosebleeds for 2 months, and deteriorating school performance with hand tremors for 1 month.

HOPI

The history is dated back to 6 months ago when the mother first noticed mild yellowish discoloration of the whites of both eyes (icterus).

• Jaundice:
  • First noticed 6 months ago, insidious in onset, fluctuating in intensity from pale lemon-yellow to deep mustard-yellow.
  • Associated with dark, high-colored urine that stains undergarments yellow Points to conjugated hyperbilirubinemia from hepatic parenchymal dysfunction and impaired biliary excretion.
  • Stools have remained normally colored (brown/yellow); no chalky or acholic stools.
  • Mild pruritus over the past 2 months, worse at night.
• Abdominal Distension (Ascites & Portal Hypertension):
  • Progressive increase in abdominal girth noticed over the last 4 months.
  • Child outgrew her skirts; abdomen became visibly rounded and protuberant with prominent blue veins across the upper tummy.
  • Mother noted dragging discomfort and heaviness in the left upper abdomen (splenomegaly) Reflects congestive splenomegaly secondary to elevated portal venous pressure.
  • Bilateral pitting pedal edema developed over the past 3 weeks, worse towards the evening.
• Bleeding Diathesis:
  • Since 2 months ago, mother noticed spontaneous purplish bruises (ecchymoses) over the shins and forearms without significant trauma.
  • Recurrent episodes of self-limiting epistaxis (3 episodes in the past month) and bleeding from gums while brushing teeth Dual etiology: impaired hepatic synthesis of vitamin K-dependent clotting factors (II, VII, IX, X) and platelet sequestration in an enlarged spleen (hypersplenism).
• Neurological & School Difficulties (Wilson Extrapyramidal Features):
  • Over the past 4-6 weeks, the school teacher reported a sharp deterioration in her academic performance.
  • Her handwriting became shaky, irregular, and progressively illegible (micrographia/tremor).
  • Mother observed coarse tremors in both hands when reaching for a glass of water, and noted that the child occasionally slurs her words and drools saliva while sleeping Classic manifestation of copper accumulation in the basal ganglia (putamen and globus pallidus), pathognomonic of neurologic Wilson disease.
• Negative History:
  • No history of vomiting blood (hematemesis) or passing black, tarry, foul-smelling stools (melena) Indicates that esophageal/gastric varices have not yet bled.
  • No history of day-night sleep reversal, inappropriate behavior, confusion, or flapping tremor Rules out overt hepatic encephalopathy (West Haven Grade 2 or higher).
  • No history of fever with diffuse abdominal pain, rebound tenderness, or chills Rules out spontaneous bacterial peritonitis (SBP).
  • No history of blood transfusions, native herbal medication, IV cannulations, or jaundice in the neonatal period.

Past History

• No prior history of acute hepatitis, blood transfusions, or major surgeries.
• No history of chronic diarrhea, steatorrhea, or recurrent chest infections (rules out cystic fibrosis).

Family history

• Born of a second-degree consanguineous marriage (parents are maternal first cousins).
• Father 38 years, farmer; mother 34 years, homemaker; both asymptomatic.
• Sibling Death: An elder brother died at 11 years of age with acute fulminant jaundice, ascites, and severe hemolytic anemia (Coombs-negative hemolytic crisis in undiagnosed Wilson disease).
• Younger brother (5 years old) is currently asymptomatic but has never been screened.

Immunization history

Summary of History

Miss Meenakshi, a 9-year-old girl, 2nd order child born of consanguineous marriage from Madurai with a family history of sibling death from fulminant jaundice, presented with a 6-month history of fluctuating icterus and dark urine, progressive abdominal distension with ascites for 4 months, easy bruising and epistaxis for 2 months, and deteriorating handwriting with tremors and academic decline for 1 month, without hematemesis, melena, or overt encephalopathy.

I would like to think of a Decompensated Chronic Liver Disease with Portal Hypertension and Cirrhosis, most likely secondary to Wilson Disease (Hepatolenticular Degeneration) with both hepatic and early extrapyramidal neurological involvement, complicated by hypersplenism and coagulopathy.

Summary

Miss Meenakshi, a 9-year-old girl, born of second-degree consanguineous parents from Madurai with a positive family history of sibling death from jaundice, presented with a 6-month history of fluctuating icterus, dark urine, progressive abdominal distension, splenomegaly, recurrent epistaxis, and bilateral hand tremors with academic decline for 1 month. Physical examination reveals bilateral golden-brown Kayser-Fleischer (KF) rings, stigmata of chronic liver disease (spider nevi, palmar erythema, leuconychia), a shrunken nodular liver (span 6.5 cm), massive splenomegaly (5.5 cm), moderate ascites with caput medusae collaterals, and extrapyramidal signs (wing-beating tremor, cogwheel rigidity, dysarthria), without active variceal bleeding or overt hepatic encephalopathy.

The clinical presentation is definitive for Decompensated Chronic Liver Disease (Cirrhosis) with Portal Hypertension, Splenomegaly, and Extrapyramidal Neurological Involvement secondary to Wilson Disease (Hepatolenticular Degeneration), Child-Turcotte-Pugh Class B/C.

Differential Diagnosis

Disease	Points IN FAVOR	Points AGAINST
Wilson Disease (Hepatolenticular Degeneration)	Age >5 years, consanguinity, sibling death, combined hepatic cirrhosis + portal hypertension + bilateral KF rings + wing-beating tremor + shrunken liver	Primary Diagnosis
Autoimmune Hepatitis (AIH Type 1 or 2)	Young female, insidious jaundice, cirrhosis, portal hypertension, hypergammaglobulinemia	Absence of KF rings, lacks extrapyramidal tremors, does not explain sibling death from acute hemolysis
Extrahepatic Portal Venous Obstruction (EHPVO)	Massive splenomegaly, portal hypertension, abdominal collaterals, normal cognitive function	Liver is normal (not shrunken/nodular) in EHPVO, jaundice is rare, stigmata of CLD absent, KF rings absent
Chronic Viral Hepatitis (Hepatitis B / C)	Cirrhosis, portal hypertension, ascites	Immunized against Hep B, no transfusion history, does not account for KF rings or neurologic manifestations
Alpha-1 Antitrypsin Deficiency	Cirrhosis, hepatosplenomegaly, portal hypertension	Lacks extrapyramidal features, no pulmonary emphysema, KF rings absent
Glycogen Storage Disease Type IV (Amylopectinosis)	Early onset cirrhosis, splenomegaly	Presents in infancy/early childhood with severe failure to thrive and death by 3-5 years; lacks ocular and basal ganglia signs

1. Wilson Disease Confirmatory Testing (Leipzig Score)

• Slit-Lamp Biomicroscopy: Positive bilateral Kayser-Fleischer (KF) rings (2 points on Leipzig score).
• Serum Ceruloplasmin: Markedly reduced ($<10\text{ mg/dL}$, normal $20-40\text{ mg/dL}$; 2 points on Leipzig score).
• 24-Hour Urinary Copper Excretion: Markedly elevated ($>100\text{ mcg/24 hours}$, normal $<40\text{ mcg/24 hours}$; 2 points).
• Total Leipzig Score: $>4\text{ points}$ (establishes a Definite Diagnosis of Wilson Disease without requiring invasive liver biopsy).
• Molecular Genetic Testing: ATP7B gene mutation analysis (identifies homozygous or compound heterozygous mutations).
• Neuroimaging (Brain MRI): T2-weighted MRI brain shows hyperintensity in the lenticular nuclei, putamen, and the classical "Face of the Giant Panda" sign in the midbrain tegmentum.

2. Hepatic Synthetic Function & Hypersplenism Workup

• Liver Function Tests (LFT):
  • Total Bilirubin: $4.6\text{ mg/dL}$; Direct Bilirubin: $3.2\text{ mg/dL}$.
  • AST ($146\text{ U/L}$) and ALT ($88\text{ U/L}$) — characteristic AST > ALT ratio $>2.0$ typical of Wilson cirrhosis.
  • Alkaline Phosphatase (ALP): Disproportionately low or normal ($98\text{ U/L}$) — highly characteristic of Wilson disease (copper displaces zinc cofactor in ALP).
  • Serum Albumin: $2.4\text{ g/dL}$ (severe hypoalbuminemia).
• Coagulation Profile: Prothrombin Time (PT) $22.5\text{ seconds}$ (Control 12s), INR 1.9 (unresponsive to parenteral Vitamin K).
• Complete Blood Count (Hypersplenism):
  • Hb $8.2\text{ g/dL}$ (normocytic normochromic, Coombs-negative hemolytic component).
  • Total Leukocyte Count: $3,100/\mu\text{L}$ (leukopenia).
  • Platelet Count: $58,000/\mu\text{L}$ (thrombocytopenia secondary to splenic sequestration).

3. Imaging & Endoscopy

• Abdominal Doppler Ultrasonography:
  • Shrunken, nodular liver parenchyma with caudate lobe hypertrophy.
  • Splenomegaly (bipolar length 14.2 cm).
  • Portal vein dilated ($11.5\text{ mm}$) with reduced, hepatofugal flow velocity; recanalized umbilical vein; moderate free ascites.
• Upper Gastrointestinal Endoscopy:
  • Reveals Grade 3 Esophageal Varices with red wale markings and mild portal hypertensive gastropathy.

Management Plan

1. Specific Copper Chelation & Decoppering Therapy

• Initial Chelating Phase (Decoppering):
  • D-Penicillamine: First-line chelator. Start low at $5-10\text{ mg/kg/day}$ to prevent paradoxical neurological worsening, then titrate weekly up to $20\text{ mg/kg/day}$ divided into two doses (administered strictly 1 hour before or 2 hours after meals).
  • Co-prescription: Oral Pyridoxine (Vitamin B6) at $25-50\text{ mg/day}$ (penicillamine is a pyridoxine antagonist).
  • Alternative: Trientine hydrochloride ($20\text{ mg/kg/day}$) if penicillamine adverse effects occur (rash, fever, proteinuria, bone marrow suppression).
• Maintenance Therapy / Induction of Intestinal Blockade:
  • Oral Zinc (Zinc Acetate / Gluconate): $50\text{ mg}$ elemental zinc three times daily (for children $>5$ years).
  • Zinc induces intestinal enterocyte metallothionein, which binds copper and prevents systemic absorption; must be spaced at least 1-2 hours apart from chelators.
• Strict Dietary Copper Restriction: Prohibit copper-rich foods: organ meats, shellfish, mushrooms, nuts, cocoa, chocolates, and unpurified water from copper vessels.

2. Management of Portal Hypertension & Variceal Bleed Prophylaxis

• Primary Prophylaxis of Variceal Hemorrhage:
  • Endoscopic Variceal Ligation (EVL / Banding): Perform elective banding of high-risk Grade 3 esophageal varices every 2-4 weeks until variceal eradication is achieved.
  • Non-Selective Beta-Blocker: Oral Propranolol starting at $0.5-1.0\text{ mg/kg/day}$ divided bid, titrating up to achieve a $20-25\%$ reduction in baseline resting heart rate (reduces portal venous inflow and HVPG).

3. Ascites & Fluid Management

• Dietary Sodium Restriction: Limit sodium intake to $<2\text{ g/day}$ ($<1-2\text{ mEq/kg/day}$).
• Dual Diuretic Therapy:
  • Oral Spironolactone at $2-4\text{ mg/kg/day}$ (aldosterone antagonist) combined with oral Furosemide at $1-2\text{ mg/kg/day}$ (maintaining standard 100:40 mg ratio to preserve serum potassium balance).
  • Monitor daily body weight (target weight loss $0.5\text{ kg/day}$).

4. Hepatic Encephalopathy Prophylaxis

• Oral Lactulose: Administer $0.5-1.0\text{ mL/kg/dose}$ two to three times daily, titrated to achieve 2 to 3 soft, acidic stools per day (promotes trapping of toxic ammonia as non-absorbable ammonium $NH_4^+$).
• Oral Rifaximin: $200\text{ mg}$ bid to reduce urease-producing gut bacterial flora.

5. Definitive Therapy & Family Screening

• Liver Transplantation Evaluation: Calculate Pediatric End-Stage Liver Disease (PELD) / Child-Pugh Score / Revised King's Wilson Index ($>11$ points predicts 100% mortality without transplantation). Living-Donor Liver Transplantation (LDLT) is curative for decompensated cirrhotic end-stage disease.
• Mandatory Screening of Relatives: Immediate screening of the 5-year-old younger brother with slit-lamp exam, LFT, serum ceruloplasmin, 24-hr urine copper, and ATP7B genetic testing (presymptomatic detection allows prevention of organ damage with oral zinc).
