Cytomegalovirus antigen-specific T cell immune responses in patients with autoimmune diseases under different cytomegalovirus infection status

[...]small sample size limited the analysis of factors affecting the CMV antigen-specific T cell immune response. [...]our study could not infer the causal relationship between CMV antigen-specific T cell immune responses and the occurrence of active CMV infection. [...]in patients with autoimmune diseases, lower CMV antigen-specific T-cell immune response was related to active CMV infection including either CMV viremia or CMV disease.
