Pediatric patients with chronic liver disease may have Minimal Hepatic Encephalopathy(MHE)which can cause changes in behavior,intelligence and neurological function.By utilizing cognitive and developmental testing we will determine if patients have MHE. If so, we will trial 3 months of blinded placebo or Lactulose treatment followed by a washout period with no treatment. At this time patients are re-tested and then begin another three month period switching to the opposite treatment of first 3 months.Final cognitive/developmental testing will determine if Lactulose treatment has any effect on MHE.

Condition Intervention Phase
Minimal Hepatic Encephalopathy Drug: Lactulose Drug: placebo Phase 2

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Crossover Assignment
Masking: Triple (Participant, Care Provider, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: Improvement of Cognitive Function and Healthcare -Related Quality of Life After Lactulose Treatment in Children With Chronic Liver Disease

Further study details as provided by Indiana University:

Primary Outcome Measures:
  • Incidence of Minimal Hepatic Encephalopathy (MHE) in Children With Cirrhosis [ Time Frame: baseline ]
    failure of one cognitive function test indicates presence of MHE

Secondary Outcome Measures:
  • Health Related Quality of Life (HRQOL) [ Time Frame: baseline ]
    HRQOL administered to parents prior to treatment

  • Effeccts of Lactulose Treatment on MHE as Measaured by Cognitive Function [ Time Frame: before and after each treatment period ]
    MHE as measured by failure of one or more cognitive test

Enrollment: 16
Study Start Date: January 2009
Study Completion Date: November 2010
Primary Completion Date: November 2010 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Lactulose
3 months of Lactulose therapy based on pt. weight
Drug: Lactulose
1.5cc/kg/day po for three months
Placebo Comparator: placebo
1.5 ml/kg day po of sugar water placebo for three months

Detailed Description:
In addition ,serum ammonia levels will be obtained at beginning of study,post-washout and at end of study to evaluate Lactulose effect on serum ammonia.
