This work was carried out onA10bshteraalctthy volunteers who served as a control group (Gl). and 50 patients with chronic renal failure. The uremic patientswere divided into 5 groups, each consisted of 10 patients. Group 2 (G2) comprised patients with negativeHBsAg. Group 3 (G3) comprised patients treated with conservative measures who are chronic healthy carrier forHBsAg. Group 4 (G4) comprisedpatients treatedwith conservativemeasures who suffered fromchronic active hepatitis due to HBV infection. Group 5 (G5) comprised diaiyzed patients who are chronic healthy carrier forHBsAg. Group 6 (G6) comprised diaiyzed pa tientswho suffered fromchronic active hepatitis due to BVinfection. The following laboratory investigations were performed to all sub jects: complete blood picture, counting ofT-lymphocytes, HBsAg, blood urea, serumcreatinine, serumbilirubin and serumtransaminases.Diagno sis of chronic active hepatitiswas confirmed by liver biopsy. Our study showed that chronic renal failure as well as haemodialysis decreased significantly bc^x total lymphocytic count and absolute T-cell count., |
