The analysis of auto‐antibodies against two types of type I interferons (IFN‐α2 and IFN‐ω) was performed using the ELISA test in 60 patients chronically infected by HIV who showed concomitant infections caused by mycobacterium tuberculosis or nontuberculosis mycobacterium or with active cytomegalovirus infections. Here, IFNA2 is linked to cytomegalovirus infection.
