Defective immune response to tetanus toxoid in hemodialysis patients and its association with diphtheria vaccination
1999
Abstract The incidence of infectious diseases is increased in patients with chronic renal failure. This is thought to be due to an impaired T cell stimulation by antigen presenting cells. Immunization programs are of great significance in the prevention of infections in immunocompromised individuals. However, the immune response to various vaccinations is impaired in patients with chronic renal failure. So far only few studies have focused on seroresponse to tetanus toxoid. Therefore we measured the levels of anti-tetanus toxoid antibodies in 71 hemodialysis patients with unknown vaccination history. The antibody levels were detected prior to and twelve months after a single “Td” or “Td–d–d” vaccination. Initially only 31 (44%) of the patients had a sufficient protection against tetanus. Of the unprotected patients 15 (38%) seroconverted after immunization, while 25 (63%) did not respond. We found a high association ( p
