||Patients with Fanconi anemia (FA) and other inherited bone marrow failure syndromes (IBMFS) have extremely high risks of squamous cell head and neck, and gynecologic carcinomas. In the general population, these sites are often associated with infection with human papillomaviruses (HPV), particularly HPV16 and HPV18. Our objectives were to measure the levels of HPV antibodies in unvaccinated patients, and to determine whether these patients developed and maintained similar levels of antibodies as those observed in healthy women, following vaccination with the currently licensed HPV L1 virus-like particles (VLP) vaccines. We measured anti-HPV IgG antibody levels in sera from patients using an HPV16 or HPV18 L1 VLP enzyme-linked immunoabsorbent assay. Most unvaccinated patients did not have detectable antibody levels, except for a few women above age 25. Both FA and other IBMFS patients developed antibody levels following vaccination that were similar to those previously described in healthy women, and those levels appeared to be sustained out to 5 years after immunization. Thus, antibody responses to the HPV L1 VLP vaccine in patients with FA and other IBMFS appeared to be similar to the responses reported in the general population, implying potential efficacy against future infections with the HPV types contained in the vaccine.
