Acute Hemolytic Crises with Fulminant
Liver Failure in Wilson’s Disease
• Rare presentation of Wilson’s disease
• Prompt liver transplantation is crucial to
survival
• Low alkaline phosphatase and uric acid : are
clues
• Coomb’s Negative Hemolytic anemia and liver
failure: a diagnostic pointer

• A 40 yr Male is brought to ER with hypotension, N/V
and diarrhea

• FH: Father: CHF and DM
• SH: Drinks 4-6 beers/day + 3 martinis x many years,
mechanic , married. No illicit drugs or smoking h/o.
Lives in Galveston, TX

Heent: Sclera- icteric, Conj -pink
• Chest: Clear
• COR: RRR
• Abdo: hepatomegaly+
• Ext: pedal edema• Skin: bullous skin lesions-purpuric, nonblanching.

Vibrio vulnificus
• V. vulnificus is concentrated in ocean filter
feeders: oysters and clams
• Primary Sepsis/septicemia: Acquired from
ingestion of raw shellfish
• Wound Infection: rapidly progressive ,
associated with exposure to estuarine waters
• Growth of the bacterium is exponential when
Fe saturation is > 70%
Vibrio vulnificus Primary Sepsis
Risk Factors
• Hereditary Hemochromatosis: 12% of patients
• Alcoholic cirrhosis: 31-43% of patients
• Underlying liver diseases including cirrhosis
and chronic hepatitis : 24-31% of patients
• Alcohol abuse without documented liver
disease: 12-27% of patients
• Chronic diseases: DM, RA, thalasemmia major,
Chr renal failure and lymphoma: 7-8% of
patients
Vibrio vulnificus Primary Sepsis
• 1/3 present in shock or become hypotensive
within 12 hrs of admission
• Thrombocytopenia and DIC is common
• A serious illness:
-Among all reported foodborne infections in
the US, it is associated with highest case
fatality rate (39%)
-Case fatality rate > 90% when hypotensive at
presentation
Case #3
• 58 y/o Caucasian female referred for > 3 year h/o
elevated liver enzymes
• C/O fatigue, RUQ abdo pain
• Past Medical History
– Obesity (BMI:40), DM, hyperlipidemia, HTN, back
pain, arthritis, depression
• No alcohol history
• FH: Mother died from cirrhosis/NAFLD
• Meds:
– Lipitor, Motrin, Effexor, Norvasc , Metformin

NAFLD
• Prevalence increasing
• Distinction between simple fatty liver and NASH with
moderate to advanced fibrosis is important
• Non-invasive testing may assist in triaging patients
for liver biopsy
• Therapeutic options remain focused on improving
insulin resistance
– Heart healthy, low processed carbohydrate diet to produce
deficit of 500-1000 cal/day
– Exercise, as adjunct to diet, focusing on aerobic activity for
30 minutes/day

NASH - Pharmacologic options
• Most evidence-based data : glitazones
• Glitazones improve : certainly steatosis and ALT,
inflammation and liver cell injury but not fibrosis
• The relationship between hepatic and metabolic
improvement need to be better understood
• Hepatoprotectants need to be developed
• Phase II studies with biochemical end-points are
needed
• Individualized therapy and integrative approaches with
diet and lifestyle modifications need to be optimized
