ABSTRACT
Serum Caffeine clearance determination is a useful method to evaluate the severity of liver disease and predict short-term survival of cirrhotic patients. Caffeine concentrations correlated well with the score indicating the sufficiency of the organ according to Child- Turcotte classification score. It offers another choice for the quantitative measurement of liver functional reservoir. Study is designed to find out the relationship of Caffeine elimination and child's classification in groups of patients with liver cirrhosis. Cross sectional Study. The study was conducted at the Medical Ward of Services Hospital Lahore from July 2004 to December 2004. Forty patients with liver cirrhosis with age range 40-55 years and 20 aged matched normal healthy volunteers were enrolled in this study. Patients were taken from the medical ward of Services Hospital Lahore. After an overnight fast, the first blood sample was collected at 8 a.m., immediately followed by an oral administration of 200 mg Caffeine. Subsequent samples of venous blood were obtained at 8.30 a.m., 9 a.m., 11 a.m., 2 p.m. and 5 p.m. The Caffeine clearance was determined by reversed-phase high pressure liquid chromatography using a Phenomenex Gemini C18 column using a wavelength of 273 nm. [Jaundice presented with highest frequency distribution and percentages. This was followed with ascities, edema. Family history of hepatitis/jaundice and anemia. Ultrasonographic findings showed that in 50% of the patients. Other 50% of patients have normal and shrunken liver]. Caffeine concentration in child class A was significantly decreased at base line [P<0.001], 3 hours [P<0.05], 6 hour [P<0.001] and 9 hour [P<0.001] as compared to the controls. In child class B the Caffeine concentration was significantly to the controls. On the other hand in child class C the Caffeine concentration was remaining same as in their controls. Caffeine clearance could provide a practical assessment of hepatic function in cirrhotic patients. Our data emphasize the value of the child-Turcotte or child-Pugh classification in assessing the severity of liver cirrhosis in a simple and less time-consuming way than using quantitative liver function tests
