Jf. Hilton et al., DEVELOPMENT OF ORAL LESIONS IN HUMAN IMMUNODEFICIENCY VIRUS-INFECTED TRANSFUSION RECIPIENTS AND HEMOPHILIACS, American journal of epidemiology, 145(2), 1997, pp. 164-174
The authors used multivariate repeated-measures transition models to i
dentify risk factors for two oral lesions related to human immunodefic
iency virus (HIV)-candidiasis and hairy leukoplakia-in 152 HIV-infecte
d blood transfusion recipients and hemophiliacs. Subjects were examine
d for occurrences of these lesions every 6 months from July 1985 throu
gh March 1993, yielding 1,076 study visits, It was found that, after a
djustment for the CD4:CD8 T-lymphocyte ratio, patients with a history
of candidiasis in the previous 18 months were at high risk of lesion r
ecurrence. This risk increased with the number of prior episodes and w
ith the recency of the episode(s). A history of hairy leukoplakia was
less predictive of persistence of that lesion after adjustment for sig
nificant risk factors (including candidiasis and use of antifungal age
nts at the current examination, a low CD4:CD8 cell ratio, and age less
than 40 years). The authors also found a high coprevalence of candidi
asis and hairy leukoplakia in these subjects. These results suggest th
at HIV-infected patients with oral candidiasis should be carefully mon
itored for subsequent episodes over the next 12-18 months, and patient
s with either oral candidiasis or hairy leukoplakia and a low CD4:CD8
cell ratio should be carefully examined for the other type of lesion a
s well.
