Working Diagnoses
• Chronic Hepatitis C Infection
• Thrombocytopenia
UNITED STATES
DEPARTMENT OF VETERANS AFFAIRS
Further work-up
• Imaging studies of the abdomen were obtained,
including MRI with contrast, which demonstrated:
• Liver cirrhosis
• Portal hypertension
• Splenomegaly, splenic varices, splenorenal shunt
• Gastroesophageal varices
• Iron deposition
• Esophago-gastro-duodenoscopy was performed as a
part of staging, and demonstrated large esophageal and
gastric varices with portal gastropathy.
UNITED STATES

Pathology
Liver Biopsy:
• Cirrhosis with mild chronic hepatitis
• 2+ iron deposition in hepatocytes
• Mild steatosis
Batts-Ludwig Grading Classification System:
• Portal/Periportal activity: 2 of 4 (mild piecemeal necrosis)
• Lobular activity: 2 of 4 (mild lobular inflammation)
• Stage: 4 of 4 (cirrhosis)
• Hereditary Hemachromatosis DNA: negative for allele
UNITED STATES

Treatment Course
• Nadolol was continued for primary esophageal variceal
hemorrhage prophylaxis.
• Citalopram was initiated for the treatment of depression.
• Immunizations for hepatitis B, seasonal influenza and
pneumococcus were administered.
UNITED STATES
DEPARTMENT OF VETERANS AFFAIRS
Treatment Course
• Treatment with recombinant human IL-11 (rHuIL-11)
was initiated to improve thrombocytopenia prior to
treatment with pegylated interferon and ribavirin.
• rHuIL-11 is a thrombopoietic growth factor that
stimulates platelet production independent of the
thrombopoietin receptor.
UNITED STATES
DEPARTMENT OF VETERANS AFFAIRS
Treatment Course
• After week 4 of rHuIL-11 therapy, the patient
developed dyspnea and lower extremity edema.
• A chest x-ray was performed and was normal.
• Spironolactone was started with resolution of the
patient’s symptoms.
• After week 8, the patient remained
thrombocytopenic, with platelet counts < 60,000.
• rHuIL-11 discontinued and patient was referred
to NYU for further evaluation.
UNITED STATES
DEPARTMENT OF VETERANS AFFAIRS
Treatment Course
• The patient was referred for screening and was
enrolled in the ENABLE trial of Eltrombopag.
• Eltrombopag is a non-peptide thrombopoietin (TPO)
mimetic that binds and activates the TPO receptor to
stimulate increased platelet production.
• During the study, the patient’s platelet values
increased from 51,000 to 136,000/mL.
• Treatment with peg-interferon and ribavirin was
initiated for treatment of chronic hepatitis C.
