HIV-1 infection is increasing more rapidly among heterosexual women. Relatively
limited information is available on HIV-related oral pathoses in these individuals.
To gain insight into the type and occurrence of oral lesions in this population, 25
HIV-^1 infected women including asymptomatic, symptomatic and AIDS patients
were examined clinically and sampled for detection of oral yeast and characteriza-
tion of their subgingival microbial flora. Sixty percent of the subjects were Afri-
can-American, with 80% infected via heterosexual contact. Oral candidiasis was
the most common nonperiodontal oral lesion, observed in 44% of the patients. Oral
yeast was cultured from all women with candidiasis and 76% of the total subjects.
Oral hairy leukoplakia was clinically diagnosed in 16% of the subjects. Clinically
mild to moderate gingivitis and periodontitis were observed in 84% and 52% of the
patients, respectively. Candidiasis and the presence of cultivable yeast were ob-
served in patients with low, intermediate, and high CD4'*" T lymphocyte numbers.
Plaque samples were collected from each subject and enumerated by predominant
cultivable methods, selective media and microscopy. No differences were detected
in the microflora associated with seropositive women with existing periodontitis
relative to those without periodontitis or to seronegative women with periodontitis.
Candidiasis was the most notable oral clitiical manifestation in the HIV-1-infected
women and may be a useful chnical indicator of early immune dysfunction medi-
ated by HIV-1.

The World Health Organization has pre-
dicted that, by the year 2000, 30-40 mil-
lion individuals tliroughout the world
will have been infected with HIV and
almost half of those will be women (60).
Cases of AIDS among women of repro-
ductive age has increased substantially
since 1981 and represents one of the
fastest-growing groups with AIDS in
the United States (6). As a result of the
revised case definition for AIDS among
adolescents and adults (7), the number
of HIV-1-seropositive women recog-
nized as having AIDS i^ increasing fur-
ther, with the highest median rate of in-
fection among black women (14, 61). In
Florida, sexual activity with multiple
partners, illicit drug use, lack of access
to health care, and socioeconomic dis-
advantage were reported to be associ-
ated with the increase in female AIDS
(12). Cumulatively, women account for
15% of all reported Florida AIDS cases
versus 10% in other states combined.
Black women account for 72% of re-
ported AIDS cases in Florida females
yet comprise only 14% of the female
population (12). In 1988, the death rate
for black women (10.3 per 100,000)
was 9 times that for white women (1.2
per 100,000) (9). There is an urgent
need for information regarding the man-
ifestations of HIV-1 infection in the pre-
dotninantly minority female popula-
tion, particularly in light of reports of
gender-related differences in disease
symptoms and progression (4, 19, 32)
and the incidence of certain opportunis-
tic infections, including esophageal can-
didiasis (11, 23).
There have been numerous reports to
date regarding oral manifestations of
HIV-1 infection, primarily in male pop-
ulations. Such oral lesions include oral
candidiasis, gingivitis and periodonti-
tis, hairy leukoplakia, other viral infec-
tions (herpes simplex virus, cytomega-
lovirus, human papiiioma virus), apht-
hous ulcers, thrombocytopenia purpura,
salivary gland disease and oral Kaposi's
sarcoma, lymphomas, and squamous
cell carcinomas (3, 18, 24, 30, 33). HIV-
1-infected individuals often demon-
strate oral manifestations as their first
sign of disease (33), with oral candidia-
sis being the most common presenting
sign (20). The identification of oral le-
