Assessment of cerulein effects on serum bile acids concentration in liver disease. Comparison with the test meal

Twenty-four liver patients and seven healthy subjects underwent the enzymatic-fluorimetric assay of total serum bile acids during fasting and after a hyperlipidic meal, both alone and with the intramuscular administration of 0.3 microgram/kg of cerulein. A third test with cerulein alone was carried out on the control group and on 12 liver patients. The liver patients were divided into two groups; those with moderate and severe liver disease, according to the degree of liver function impairment and the clinical data. The best discriminant efficiency was observed in the test with the meal alone, even if, in the liver patients, the meal with cerulein caused a greater percentual increase of serum bile acids. After taking into account the most significant correlations between serum bile acids and liver function tests, the addition of cerulein to the meal may be recommended for liver patients with previous cholecystectomy or gallbladder pathology.
