Variations in anti-CMV antibody affinity have been studied in 106 renal transplant patients. Maturation of immune response has been followed during two years after transplantation evaluating antibody affinity by ELISA before and after urea denaturation treatment. In primary infections while the antibody titer rises, the resistance to denaturing treatment rises as well, indicating an increased antibody affinity. In patients already seropositive at transplantation, the increase of antibody affinity has also been found: comparing the affinity index (AI) at transplantation and one year later, only 16.5% of patients showed an AI value between 80 and 100 at transplantation, whereas after one year 62.3% of patients reached such AI values (p = 0.0001).

Abstract

Variations in anti-CMV antibody affinity have been studied in 106 renal transplant patients. Maturation of immune response has been followed during two years after transplantation evaluating antibody affinity by ELISA before and after urea denaturation treatment. In primary infections while the antibody titer rises, the resistance to denaturing treatment rises as well, indicating an increased antibody affinity. In patients already seropositive at transplantation, the increase of antibody affinity has also been found: comparing the affinity index (AI) at transplantation and one year later, only 16.5% of patients showed an AI value between 80 and 100 at transplantation, whereas after one year 62.3% of patients reached such AI values (p = 0.0001).
