To investigate the role of host susceptibility to HIV-1 infection, we studied subsequent seroconversion in 161 individuals, initially seronegative to HIV-1, who underwent skin testing for cutaneous anergy at an index visit within a prospective study of homosexual men. There were 23 seroconversions in these men by 45 months following the skin testing, yielding a crude rate of seroconversion of 14.3%. While results of purified protein derivative (PPD), Candida, and Trichophyton skin tests were not associated with subsequent course, anergy to dinitrochlorobenzene (DNCB) was predictive of subsequent seroconversion. Kaplan-Meier estimates for the risk of seroconversion during 45 months of follow-up in those men initially anergic and reactive to DNCB were 28.9 and 11.1%, respectively, yielding a relative risk of 2.6 (p = 0.006). The estimated relative risk was stable with adjustment by Cox regression for annual number of male sexual partners and frequency of receptive anal intercourse, and was not sensitive to various changes in the definition of seroconversion time and of eligibility criteria. These data suggest that an impaired host immune status may be associated with an increased risk of HIV-1 infection that is independent of risk of exposure to the virus, supporting earlier speculations that HIV-1 may itself be opportunistic. The notion of varying host susceptibility to infection, at least with regard to sexual transmission in homosexual men, may help to explain the frequent observation of individuals who have been repeatedly exposed to the virus and yet have remained uninfected.
