Abstract
In our study, 136/268 individuals were long-term CMV seropositive and 19 seroconverted during follow-up (seroconversion rate: 0.56%/year). CMV-specific antibody levels increased slightly over time. However, we did not find an association between duration of CMV infection and CMV-specific antibody levels at study endpoint. No clear association between duration of CMV infection and the size and function of the memory T-cell pool was observed. Elevated CMV-specific antibody levels were associated with the prevalence of cardiovascular disease but not with frailty. Age at CMV seroconversion was positively associated with CMV-specific antibody levels, memory CD4+ T-cell numbers and frailty.
