The accurate diagnosis of oral lesions in human immunodeficiency virus infection. Impact on medical staging

Oral Lesions of HIV Disease and HAART in Industrialized Countries

The epidemiology of HIV-related oral disease in industrialized nations has evolved following the initial manifestations described in 1982. Studies from both the Americas and Europe report a decreased frequency of HIV-related oral manifestations of 10–50% following the introduction of HAART (highly active antiretroviral therapy). Evidence suggests that HAART plays an important role in controlling the occurrence of oral candidosis. The effect of HAART on reducing the incidence of oral lesions, other than oral candidosis, does not appear as significant, possibly as a result of low lesion prevalence in industrialized countries. In contrast to other oral manifestations of HIV, an increased prevalence of oral warts in patients on HAART has been reported from the USA and the UK. HIV-related salivary gland disease may show a trend of rising prevalence in the USA and Europe. The re-emergence of HIV-related oral disease may be indicative of failing therapy. A range of orofacial iatrogenic consequences of HAART has been reported, and it is often difficult to distinguish between true HIV-related oral disease manifestations and the adverse effects of HAART. A possible association between an increased risk of oral squamous cell carcinoma and HIV infection has been suggested by at least three epidemiological studies, with reference to the lip and tongue. These substantial and intensive research efforts directed toward enhancing knowledge regarding the orofacial consequences of HIV infection in the industrialized nations require dissemination in the wider health care environment.

Dental anxiety and the use of oral health services among people attending two HIV primary care clinics in Miami

OBJECTIVES

We examined factors associated with dental anxiety among a sample of HIV primary care patients and investigated the independent association of dental anxiety with oral health care.

METHODS

Cross-sectional data were collected in 2010 from 444 patients attending two HIV primary care clinics in Miami-Dade County, Florida. Corah Dental Anxiety Scores and use of oral health-care services were obtained from all HIV-positive patients in the survey.

RESULTS

The prevalence of moderate to severe dental anxiety in this sample was 37.8%, while 7.9% of the sample was characterized with severe dental anxiety. The adjusted odds of having severe dental anxiety were 3.962 times greater for females than for males (95% confidence interval [CI] 1.688, 9.130). After controlling for age, ethnicity, gender, education, access to dental care, and HIV primary clinic experience, participants with severe dental anxiety had 69.3% lower adjusted odds of using oral health-care services within the past 12 months (vs. longer than 12 months ago) compared with participants with less-than-severe dental anxiety (adjusted odds ratio = 0.307, 95% CI 0.127, 0.742).

CONCLUSION

A sizable number of patients living with HIV have anxiety associated with obtaining needed dental care. Routine screening for dental anxiety and counseling to reduce dental anxiety are supported by this study as a means of addressing the impact of dental anxiety on the use of oral health services among HIV-positive individuals.

A comparison of unmet needs for dental and medical care among persons with HIV infection receiving care in the United States

OBJECTIVE

Oral health conditions associated with HIV disease are frequently more severe than those of the general population, making access to both dental and medical care important. Using the domains specified in the Behavioral Model of Health Services Use, this paper examines the correlates of unmet needs for dental and medical care in a nationally representative sample of patients with HIV.

METHODS

This investigation is a cross-sectional study using baseline data from the HIV Cost and Services Utilization Study (HCSUS), the first nationally representative study of persons in care for HIV. Using probability-based techniques, 4,042 people were randomly selected in January 1996, and 2,864 (71%) completed a structured interview that included questions on unmet needs for dental and medical care. Regression analysis was used to identify variables associated with having unmet needs for dental care only, medical care only, and both medical and dental care.

RESULTS

Of the estimated 230,900 people in treatment for HIV in the United States, approximately 58,000 had unmet medical or dental needs based on self-reported data. Unmet dental needs were more than twice as prevalent as unmet medical needs (32,900 vs 14,300), and 11,600 people were estimated to have both types of unmet needs. Multinomial logit regression showed that persons with low income had increased odds of reporting unmet needs for both dental and medical care. The uninsured and those insured by Medicaid without dental benefits had more than three times the odds of having unmet needs for both types of care than did the privately insured.

CONCLUSIONS

To serve both the dental and medical needs of diverse populations affected by HIV disease, greater coordination of services is needed. In addition, state insurance programs for people with HIV should consider the feasibility of expanding their benefit structure to include dental care benefits.

Prevalence of HIV-1 and oral lesions in pregnant women in rural Malawi

OBJECTIVE

Whether oral lesions were associated with human immunodeficiency virus-type 1 (HIV-1) status in a cohort of pregnant Malawian women was studied.

STUDY DESIGN

Six hundred thirty-eight women participated in a randomized prospective study at 3 prenatal clinics in a rural area of southern Malawi. Oral examinations, followed by collection of oral fluid specimens with an HIV-1 oral specimen collection device, were performed. The specimens were tested for antibodies against HIV-1.

RESULTS

Sixty-one oral lesions were found in 60 participants. While traditional HIV-1 associated lesions were rare, benign migratory glossitis was unexpectedly common (6%). Oral hairy leukoplakia was significantly more common among women who were HIV-1 positive than among women who were HIV-1 negative. An HIV-1 prevalence rate of 21.8% was estimated among the women, with the highest rate of HIV-1 infection (34.1%) among women aged 25 to 29 years.

CONCLUSION

Stratifying lesions showed a small number of oral hairy leukoplakia to be markers for HIV-1. A high seroprevalence was found in this rural cohort, but there were unexpectedly few oral lesions. The relatively few oral lesions diagnosed may indicate a recent infection with HIV.

Occurrence of oral lesions in relation to clinical and immunological status among HIV-infected adult Tanzanians

OBJECTIVE

To determine the association, if any, between the presence of oral lesions and clinical and immunological status of untreated HIV-infected adults in Tanzania.

DESIGN

A cross-sectional study.

SETTING

AIDS Clinical Trial Clinic (ATCC) at Muhimbili Medical Centre in Dar-es-Salaam, Tanzania.

SUBJECTS

192 HIV-infected individuals not receiving treatment; 156 individuals confirmed to be HIV-seronegative acted as a control group.

METHODS

Examination of oral structures, determination of HIV serostatus, clinical status, and peripheral CD4+ T cell and total lymphocyte counts.

MAIN OUTCOME MEASURE

Presence of oral lesions.

RESULTS

Intra-oral lesions were seen among 7.7% of the HIV-seronegative, 10.4% of the HIV-seropositive and 36.8% of the AIDS groups, respectively. Enlarged parotid glands were seen in 20% of the AIDS patients, 11.9% of the HIV-seropositives, and 5.1% of the HIV seronegatives. Enlargement of submandibular salivary glands was seen in 29.6% of the AIDS patients, 31.3% of the HIV-seropositives compared with 14.7% among the HIV-seronegatives. Multiple regression analysis was used to calculate adjusted odds ratio (OR) for presence of oral lesions. OR for an intra-oral lesion was 1.6 (95% CI = 0.5; 5.0) among the HIV-seropositives and 8.2 (95% CI = 3.5; 19.7) among the AIDS patients using the HIV-seronegatives as reference. OR for an intra-oral lesion was 0.9 (95% CI = 0.3; 2.9) in HIV-infected patients with peripheral CD4+ T cell count of between 200-500 cells mm-3 and 2.7 (95% CI = 0.9; 7.7) in patients with less than 200 cells mm-3. OR for an intra-oral lesion was 0.4 (95% CI = 0.2; 0.9) for patients with peripheral total lymphocyte counts of between 1000-2000 cells mm-3 and 0.9 (95 CI = 0.4; 2.0) for patients with less than 1000 cells mm-3.

CONCLUSION

The association of oral lesions with the clinical stage of HIV infection and to a lesser extent peripheral CD4+ T cell count does suggest that these lesions could be used as additional markers of immunosuppression and AIDS.

Oral examination: a screening tool for HIV infection?

OBJECTIVE

To estimate the predictive values for HIV infection of diagnosis of oral manifestations of the infection.

METHOD

Prevalence of oral manifestations was compared in cross sectional blinded clinical examinations of homosexual men attending a genitourinary medicine clinic. Data were extrapolated to populations in England and Wales based on estimates of the prevalence of HIV infection.

RESULTS

Data were analysed for 572 HIV infected and non-infected men (312 and 260 respectively). Positive predictive values for erythematous candidiasis, hairy leucoplakia and pseudomembranous candidiasis were greater than 0.96 at the genitourinary medicine clinic and are estimated to be greater than 0.72 among homosexual men in London.

CONCLUSIONS

Clinical diagnoses of mucosal lesions alone are poor predictors of HIV infection but are useful when used in conjunction with a social history to establish if there are risk factors for infection.

Sentinels and signposts: the epidemiology and significance of the oral manifestations of HIV disease

A large number of studies attest to the frequency of oral disease in those with HIV infection. Most show that hairy leukoplakia and pseudomembranous candidiasis are the commonest lesions in those with HIV infection and AIDS, with higher prevalence and incidence rates correlating with falling CD4 counts and disease progression. HIV-infected individuals with oral candidiasis or hairy leukoplakia progress to AIDS more rapidly than matched controls without these lesions. Oral candidiasis and hairy leukoplakia increase with time since seroconversion. On the other hand, parotid enlargement in children appears to be associated with slower progression to AIDS. As a consequence of these and other observations, oral lesions are widely included in natural history studies, staging and classification schemes for HIV infection. In addition to their role in the diagnosis of HIV infection and as indicators of the progression of HIV disease, oral lesions are used as clinical correlates of CD4 counts and as criteria for entry into clinical trials.
