title: Herpes zoster and the stage and prognosis of HIV-1 infection.
abstract: OBJECTIVE
  To examine the incidence of herpes zoster in HIV-1 infection. To assess the prognostic significance of the occurrence of herpes zoster and progression to AIDS or death
  
  
  METHODS
  146 homosexually active men with known times of HIV-1 seroconversion were identified through the Sydney AIDS Prospective Study and the clinic records of a private medical practice with large caseload of HIV infected homosexual men. Medical records were reviewed for a history of herpes zoster, CD4+ lymphocyte counts, and HIV-1 disease status. Cox's proportional hazards model was used to determine whether herpes zoster predicted progression to AIDS or death.
  
  
  RESULTS
  After a mean follow up of 54 months, 30 men (20%) had an episode of herpes zoster and three of these men had one recurrence. The overall incidence of herpes zoster was 44.4 episodes per 1000 person years (95% CI 30.0-63.5). Herpes zoster was not found to be a marker of deteriorating immune functions as measured by CD4+ lymphocyte counts. CD4+ counts did not differ significantly between those with and without zoster at 1 year (551 v 572.10(6)/1, p = 0.79), 2 years (451 v 557, p = 0.11), and 3 years (424 v 481, p = 0.50) following HIV-1 seroconversion. There was no statistically significant difference in progression to AIDS (RR = 1.89, 95% CI 0.80-4.46, p = 0.15) or death (RR = 0.90, 95% CI 0.31-2.65, p = 0.85) from HIV-1 sero-conversion in those who did and those who did not develop herpes zoster.
  
  
  CONCLUSIONS
  The incidence of herpes zoster was consistent with the findings of other studies. There was no association between the occurrence of herpes zoster and progression of HIV-1 disease.
