ABSTRACT
The B.C of our study was to assess the level of IgA and transferrin of patients with liver cirrhosis to determine the relation between liver cirrhosis and IgA/transferrin ratio. The study involved 32 subjects classified into patients without liver cirrhosis [n=12], and patients with liver cirrhosis [n=10] as well as a group of normal healthy subjects [n=10] for comparison. In all of these subjects, serum alanine [ALT] and aspartate [AST] aminotransferase activity as well as serum IgA and transferrin level were determined. Our results revealed that the mean values of both ALT and AST activities were significantly high in both groups of patients without liver cirrhosis and with liver cirrhosis [P<0.05], although the activity of both enzymes was relatively higher in patients with liver cirrhosis than in those without liver cirrhosis. Furthermore, the amount of IgA immunoglobulin showed very highly significant decreased values in patients without liver cirrhosis while very highly significant increased values were obtained in cirrhotic patients as compared to their corresponding values in normal group. The concentration of serum transferrin showed insignificant values in cases without liver cirrhosis whereas these values showed moderately significant decreased level in cases of liver cirrhosis. It is of interest that the values of IgA/transferrin ratio, although showed insignificant values in patients without liver cirrhosis these values were significantly high in cirrhotic patients. In addition, it has been found that in liver cirrhotic patients the mean values of IgA/transferrin ratio were nearly 2.5 times as compared to the ratios in normal or non-cirrhotic patients. From the present study, the determination of IgA and transferrin in serum or plasma may open up a very simple and safe way for the early detection of latent cirrhosis. IgA/transferrin>2.5 ratio was found to be significantly increased in latent cirrhosis as compared to patients without cirrhosis or normal subjects. This value can be considered as an indicator of latent cirrhosis in children associated with liver diseases
