Association of cutaneous and oral diseases in HIV-infected men

OBJECTIVES: Mucocutaneous diseases are common in patients infected with human immunodeficiency virus (HIV). To identify cutaneous diseases for which HIV-infected people are at high risk, we sought those that are strongly associated with specific HIV-related oral lesions and with progression of HIV disease.
DESIGN: A cross-sectional study of HIV-positive outpatients referred to a university stomatology clinic for diagnosis and treatment of oral diseases. Each subject underwent both complete oral and cutaneous examinations.
RESULTS: Among 55 men, with a median age of 41 years and a median CD4 cell count of 125/ju.l (range 0–950/pil), 93% had active oral diseases or conditions, including candidiasis, hairy leukoplakia, ulcers, Kaposi's sarcoma (KS), and xerostomia, and 95% had skin conditions, including onychomycosis, dermatophytosis, seborrheic dermatitis, KS, folliculitis, xerosis, and molluscum contagiosum. Seborrheic dermatitis, xerosis, skin KS, and molluscum contagiosum were associated with oral HIV-sentinel lesions (oral candidiasis, hairy leukoplakia, and KS), with low CD4 cell counts, and with AIDS.
CONCLUSION: Our results suggest that xerosis and seborrheic dermatitis may be early harbingers of HIV disease progression. Their roles as predictors warrant further study, based on their associations with low CD4 cell counts and AIDS and strong co-prevalence with one of the most common HIV-related oral lesions, oral candidiasis.     

Oral lesions as indicators of HIV infection among routine dental patients in Lagos, Nigeria

OBJECTIVES: To document the incidental oral lesions of human immunodeficiency virus (HIV) infection, the pattern and frequency of the lesions based on clinical presentation and oral manifestations in routine dental patients who tested positive in Nigeria. SUBJECTS AND METHODS: The study was conducted at the Oral Diagnosis/Oral Medicine clinic of the Lagos University Teaching Hospital, Lagos, Nigeria between May 2002 and April 2003. During this period, all patients with oral lesions suggestive of HIV/acquired immunodeficiency syndrome (AIDS) as described in the EEC-WHO Classification and diagnostic criteria of oral lesions of HIV were counseled and offered voluntary HIV testing. All the 35 patients who consented and tested positive were included in this study. RESULTS: Of a total of 700 patients 53 patients with oral lesions suggestive of HIV/AIDS were seen, thirty-eight (72%) consented to HIV screening, 15 patients (28%) refused. Thirty-five patients (92%), mean age 36 +/- 13 years were confirmed positive for HIV. Oral candidiasis was the commonest lesion seen (43%) the second common being Herpes zoster (23%). Other lesions seen included erythema multiforme in two (6%), facial palsy in two (6%) and oral hairy leukoplakia in one (3%). CONCLUSION: An oral mucosal lesion may be the presenting lesion of HIV/AIDS in routine patients attending the dental clinic. Oral health care workers should practice optimal infection control based on the Centers for Disease Control 'Standard Precautions' guidelines on infection control for all patients to minimize occupational transmission of HIV.     

Sensitivity, specificity, and positive predictive value of oral opportunistic infections in adults with HIV/AIDS as markers of immune suppression and viral burden

OBJECTIVES: The purpose of this study was to assess the use of human immunodeficiency virus (HIV)-related oral opportunistic infections as markers of immune suppression and viral burden in adults with HIV/acquired immunodeficiency syndrome (AIDS). METHODS: The population consisted of a single institution observational cohort involving 606 patients with HIV/AIDS with CD4 count data and 277 with plasma viral load measurements examined between 1995 and 1999 for the presence of oral manifestations of HIV. Sensitivity, specificity, positive predictive value (PPV), and negative predictive value is reported for the association of specific oral lesions and lesion sets with CD4 counts <200 cells/mm(3) and with plasma HIV RNA >/=20,000 copies/mL. RESULTS: Lesions with moderate-to-high PPVs for CD4 <200 cells/mm(3) were as follows: Kaposi's sarcoma (100%; P =.035), pseudomembranous candidiasis (82. 2%; P <.001), linear gingival erythema (70.0%; P =.015), hairy leukoplakia (66.3%; P <.001), angular cheilitis (60.0%; P =.128), and erythematous candidiasis (58.3%; P =.061). Necrotizing ulcerative periodontal diseases, HIV salivary gland disease, oral ulcers, and oral warts had PPVs below 50%. Concurrent infection with candidiasis and hairy leukoplakia had the highest PPV of 89.3%; P <. 001. PPVs for HIV RNA >/=20,000 copies/mL ranged from 27.3% to 100%, with significant association only for pseudomembranous candidiasis. CONCLUSIONS: Specific common oral lesions are strongly associated with immune suppression, as measured by CD4 cell counts, and are modestly associated with high viral burden, thus serving as potential clinical markers of HIV viremia and the consequent destruction of the immune system with progressive HIV disease.     

Oral lesions associated with HIV/AIDS in HIV‐seropositive patients attending a counselling and treatment centre in Dar es Salaam

Objective: To assess the prevalences and patterns of oral lesions occurring in human immunodeficiency virus (HIV) and acquired immune deficiency syndrome (AIDS). Methods: A cross‐sectional study was conducted among 200 people living with HIV/AIDS (PlwHA) who regularly attended a counselling and treatment centre in Dar es Salaam, Tanzania. A questionnaire‐guided interview and clinical oral assessment were used. Strict confidentiality and adherence to ethical codes were observed. Results: The mean age of participants was 38.91 years (standard deviation: 10.424; mode: 35 years; median: 37.0 years; range: 15–76 years). Most participants (58.5%) were aware of predispositions towards the occurrence of oral lesions such as oral candidiasis (60.0%) in HIV/AIDS and most of these (72.0%) were aware that the lesions are treatable. Some participants reported occurrences of oral thrush (22.5%) and lip ulcerations (28.5%), although only 47.0% of these had sought medical advice. Examinations revealed that 29.0% of participants had at least one oral lesion associated with HIV/AIDS. Prevalences of the various types of lesion were: 11.5% for herpes simplex; 7.5% for oral candidiasis; 4.0% for oral hairy leukoplakia; 3.5% for Kaposi’s sarcoma; 1.5% for dry mouth; 0.5% for angular cheilitis, and 0.5% for acute necrotising ulcerative gingivitis. Herpes simplex and Kaposi’s sarcoma were more frequently observed in males (56.5% and 71.4%, respectively), whereas oral candidiasis and dry mouth were observed more often in females (86.7% and 66.7%, respectively) (χ² = 16.692, P = 0.016). Conclusions: Prevalences of oral lesions associated with HIV/AIDS in PlwHA and using antiretroviral therapy are persistent, of moderate intensity and vary according to individual immune status. These patients’ level of awareness about oral lesions was satisfactory, but formal medicodental lines of management were not prioritised. Contemporary protocol for the management of oral lesions should be understood and disseminated to the general public by dentists.     

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.     

Oral manifestations in HIV-positive adults from Northern Thailand

Eighty-seven HIV-infected patients in a provincial hospital in Northern Thailand were examined for oral manifestations of HIV disease and AIDS. The median age was 31.3 years. Seventy-four of the patients were women, 13 were men. 96.6% had a history of heterosexual transmission. Sixty-one patients were CDC-category A, 20 were category B and 6 were category C (AIDS). Thirty-eight percent of the patients revealed oral lesions; 23% had one oral lesion and 13.8% had two oral lesions. Common lesions were oral candidiasis (10.3% pseudomembranous candidiasis, 6.9% erythematous candidiasis and 3.4% both forms), oral hairy leukoplakia (11.5%) and exfoliative cheilitis (6.9%). Gingival linear erythema was seen in 8% of the patients; periodontal lesions and necrotising ulcerative gingivitis were not observed. Men were more commonly affected by oral manifestations than women (P < 0.004). The spectrum of oral lesions is comparable to other studies from the region, although most of these reported more men than women. Also, the degree of immunosuppression was more marked (AIDS).     

Oral manifestations in HIV/AIDS infected patients from India

OBJECTIVES: To assess types and prevalence of HIV-related oral lesions among HIV-infected individuals in south India and to correlate common oral findings with co-morbidities, gender, age and medication. SUBJECTS AND METHODS: One hundred and one patients with HIV infection or AIDS at infectious diseases units of Attavar Hospital, Mangalore, and medical wards of Kasturba Medical College, Manipal, were selected. Sociodemographic information was obtained using a structured questionnaire. Oral lesions were diagnosed according to the presumptive criteria of EEC-Clearinghouse Classification. Clinical history was retrieved from patient's medical records. RESULTS: Erythematous candidiasis (44.5%), melanotic hyperpigmentaion (34.6%) and xerostomia (29.7%) were among the most common oral manifestations. A significant association was found between oral candidiasis and advanced immunosuppression (P < 0.05). Oral hairy leukoplakia (OHL) was predominant in individuals <35 years (P < 0.05). Melanotic hyperpigmentation was significantly associated with highly active antiretroviral therapy (P < 0.05). OHL was more frequent in patients with HIV-associated tuberculosis. Linear gingival erythema was more predominant in females. CONCLUSIONS: Oral hairy leukoplakia showed a positive relationship with patients younger than 35 years. Oral candidiasis can act as a marker for immunosuppression. Angular cheilitis was predominant in the symptomatic stage.     

Patterns of oral manifestation of HIV/AIDS among 225 Nigerian patients

Objective:  The purpose of this study was to determine the prevalence of the oral manifestations of HIV/AIDS and to correlate the prevalence of these lesions with the stages of the disease in the Ife-Ijesa zone, Nigeria. No comprehensive data were available for correlating it with the staging of HIV/AIDS in this region.
Subjects:  The pattern of oral HIV lesions as classified by the EC-Clearinghouse was studied in 225 confirmed consecutive HIV-infected patients in this zone.
Methods:  Clinical dental examinations were conducted under natural daylight on all consenting HIV patients, sitting in an upright chair, using dental mirrors and probes.
Results:  The prevalence of oral HIV lesions was 84.0%, with lesions ranging in number from one to six. The commonest HIV lesion was pseudo-membranous candidiasis (43.1%) followed by erythematous candidiasis (28.9%), angular cheilitis (28.9%), linear gingival erythema (24.0%) and ulcerations (8.9%). Lesions less commonly found were oral hairy leukoplakia (1.3%) and salivary gland swellings (1.3%). Heterosexual intercourse was the most common mode of transmission (94.7%) and HIV-1 (96.9%) the most prevalent pathogen among the study population. The majority of the patients were in the WHO clinical stage III (59.1%) and presented late.
Conclusions:  The prevalence of oral HIV lesions in the present study was high.     

Oral lesions in HIV-positive dental patients--one more argument for tobacco smoking cessation

OBJECTIVE: To determine the prevalence of oral lesions associated with human immunodeficiency virus (HIV) in a population of dental patients and analyze its association with psycho-social variables and biological markers. STUDY DESIGN: The dental charts of 415 dental patients consecutively treated between May and July 2005 in a dedicated HIV dental clinic were reviewed. Oral soft tissue examinations, psycho-social and medical variables were extracted and recorded for each patient. Ethnicity, gender, HIV treatment, peripheral CD(4) counts and tobacco usage were analyzed in correlation with oral lesions associated with HIV. RESULTS: Fifty-five percent of all subjects had at least one oral lesion associated with HIV, with oral candidiasis, salivary gland enlargement and oral hairy leukoplakia being the most commonly observed conditions. Gender and ethnicity did not correlate with a higher prevalence in lesions. However, tobacco smoking correlated significantly with a higher prevalence of oral lesions, independent of CD(4) counts. CONCLUSIONS: These findings suggest that oral lesions remain commonly observed morbidities among HIV-infected dental patients independent of gender and ethnicity and that tobacco usage is a major and often underestimated risk factor for those lesions.     

HIV-associated oral lesions; immunologic, virologic and salivary parameters

There are numerous reports of oral lesions in HIV-infected individuals. However, few correlate the oral lesions with laboratory parameters. This study examined oral candidiasis and hairy leukoplakia, the two most common HIV-associated oral lesions, in relation to T-cell counts, p24 core antigen levels and salivary flow rates. Oral mucosal examinations, immunologic and virologic studies and stimulated whole and parotid saliva flow rates were conducted on 135 (HIV+ = 102, HIV- = 33) homosexual or bisexual men. Results indicate that, among HIV-infected subjects, the odds of having oral candidiasis is 6 times (95% CI = 0.6-56.6) greater for subjects with T4 counts between 200-399 per mm3, and 23 times (95% CI = 2.8-193.0) greater for subjects with T4 counts less than 200/mm3 compared to subjects with T4 counts of 400/mm3 or greater. Subjects had an equal likelihood of having hairy leukoplakia at different levels of immunocompetence. The prevalence of oral candidiasis and hairy leukoplakia was higher among subjects with infectious virus in their serum, but was only statistically significant for hairy leukoplakia (p = 0.01).     

Oral manifestations associated with human immunodeficiency virus infection in a Spanish population

A study was made of the oral manifestations in 396 patients with human immunodeficiency virus (HIV) infection. The following risk groups were established: intravenous drug users (79.5%), homosexuals (7.8%), homosexual intravenous drug users (3.3%). heterosexuals (8.1%) and hemophiliacs/transfusion patients (1.3%). The oral lesions, in decreasing order of frequency, were: periodontal disease (78.28%). candidiasis (65.65%). hairy leukoplakia (16.16%). herpes simplex virus lesions (5.30%), Kaposi's sarcoma (2.27%), recurrent aphthous ulceration (RAS) (1.01%), lichen planus (0.5%), non-Hodgkin's lymphoma (0.25%). tuberculous lesion of the tongue (0.25%) and ulcerations of uncertain etiology (0.25%). Attention is drawn to the greater predominance of these lesions in patients with CD4 values of less than 200/mm³, compared with those who have higher lymphocyte counts.     

Oral manifestations of HIV infection in 75 Dutch patients

Seventy-five consecutive HIV-infected patients, including 33 AIDS cases were examined. One or more oral mucosal lesions were observed in 57 (76%); candidiasis was the most common finding (52%). Others included hairy leukoplakia (16%), periodontal disease (16%) and Kaposi's sarcoma (4%). Diversity of study design and methods allowed no reliable comparison with other reports.     

Oral manifestations of AIDS: an overview

Infection with the human immunodeficiency virus (HIV) may cause a variety of oral lesions, such as candidiasis, periodontal disease, hairy leukoplakia, Kaposi's sarcoma and a number of miscellaneous lesions and conditions. One hundred HIV-infected patients, including AIDS patients, referred to a University Hospital in Amsterdam, were examined orally. Most patients were initially seen by the Department of Internal Medicine, the oral examination by a well-trained dentist being part of the routine screening of all HIV-infected patients. In 80 per cent of all patients one or more HIV-related lesions of the oral mucosa was recorded. In 6 per cent of those patients the oral lesion was the first manifestation of the HIV infection. Hairy leukoplakia was observed in 15 per cent of all patients. Candidiasis proved to be the most common oral disease. In patients with full-blown AIDS the pseudomembranous form of candidiasis was the most common one, while in HIV-infected patients the erythematous type prevailed. These results emphasize the role of the dentist in making an early diagnosis of HIV infection.     

Ability of HIV/AIDS patients to self-diagnose oral opportunistic infections

OBJECTIVES: To assess the accuracy of HIV/AIDS patients' self-diagnosis of common HIV-related oral opportunistic infections. METHODS: 245 HIV/AIDS patients were interviewed regarding the current presence of oral candidiasis (OC), oral hairy leukoplakia (OHL), and oral ulcers prior to an oral examination by an oral medicine trained dentist examiner. Sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) are reported for the patient's oral lesion diagnosis compared to the dentist's diagnosis based on established presumptive clinical criteria as the gold standard. RESULTS: Self-diagnosis accuracy was greatest for pseudomembraneous OC (PPV 42.9%; NPV 93.5%), followed by oral ulcers (PPV 35.7%; NPV 98.3%) and OHL (PPV 23.5%; NPV 86.4%). Past experience with the lesion improved diagnostic accuracy, and bothersome symptoms accompanying the lesion had significant impact only for pseudomembraneous OC and oral ulcers. CONCLUSIONS: Moderate accuracy of patient self-assessment of oral lesions, with tendency to under rather than over report lesion presence, supports the use of patient self-assessment of these lesions to augment clinician diagnosis in clinical trials. Additionally, HIV/AIDS patients are unlikely to believe they have active OC that would lead to on-demand antifungal use, unless they have had prior experience with the lesion or it is at least moderately bothersome.     

Oral lesions in Mexican HIV-infected patients

One hundred and twenty-five HIV-infected patients, of whom 49 (39%) were at early stages of the infection (CDC-II & III) and 76 (61%) in CDC IV, were prospectively examined. In 100 (80%) one or more oral mucosal lesions were observed; candidiasis (51%) and hairy leukoplakia (43%) were the commonest. Erythematous candidiasis was more often seen (35%) than the pseudomembranous type (16%), and appeared with the higher values at early than later stages. The prevalence of hairy leukoplakia, oral hyperpigmentation and xerostomia were incremented in groups CDC-IV. Pseudomembranous candidiasis and exfoliative cheilitis increased significantly with severity of disease. Our study demonstrates that oral alterations associated to HIV are a frequent finding, both at early (76%) and late (83%) stages of the infection in Mexican patients.     

Oral manifestations in 45 HIV-positive children from Northern Thailand

Forty-five Northern Thai children with HIV infection or AIDS were examined for oral manifestations. Of these children, 51.1% (n=23) were asymptomatic (category N), 48.9% were mildly, moderately or severely symptomatic (category A, B, C) and 48.9% (n=22) revealed oral lesions. Eleven patients (24.4%) showed one oral lesion, eight (17.8%) had two and three (6.6%) had three oral lesions. Erythematous candidiasis was the most common lesion (17.8%). Oral hairy leukoplakia was seen in 6.7% (n=3). Geographic tongue, not usually considered to be associated with HIV infection, was seen in 6.7% (n=3). Only 15 patients (33.3%) received antiretroviral therapy (ART). Comparison of patients with or without ART did not show differences in the prevalence of oral lesions. More studies in Thai HIV-infected children are needed to reveal the prevalence of oral manifestations, as well as for the predictive value of the most common or specific oral manifestations.

(A3) HIV Phenotypes, oral lesions, and management of HIV-related disease

Workshop participants discussed: the role of HIV subtypes in disease; the treatment of oral candidiasis; the relationship between and among viral load, CD4+ counts, oral candidiasis and oral hairy leukoplakia, pigmentation; and the development of a reliable oral index to predict disease progression. Regarding HIV, the literature revealed that Type I (HIV-I), in particular group M, is involved in the majority (90%) of documented infections, and groups N and O to a lesser extent. Viral envelope diversity led to the subclassification of the virus into nine subtypes, or clades-A-D, F-H, J, and K-each dominating in different geographical areas. HIV-2, currently occurring mostly in West Africa, appears to be less virulent. No evidence could be produced of any direct impact of type, subtype, or clade on oral lesions, and participants believed that further research is not feasible. Oral candidiasis in patients from resource-poor countries should be prevented. When the condition does occur, it should be treated until all clinical symptoms disappear. Oral rinsing with an antimicrobial agent was suggested to prevent recurrence of the condition, to reduce cost, and to prevent the development of antifungal resistance. Lawsone methyl ether, isolated from a plant (Rhinacanthus nasutus leaves) in Thailand, is a cost-effective mouthrinse with potent antifungal activity. Evidence from a carefully designed prospective longitudinal study on a Mexican cohort of HIV/AIDS patients, not receiving anti-retroviral treatment, revealed that the onset of oral candidiasis and oral hairy leukoplakia was heralded by a sustained reduction of CD4+, with an associated sharp increase in viral load. Analysis of the data obtained from a large cohort of HIV/AIDS patients in India could not establish a systemic or local cause of oral melanin pigmentation. A possible explanation was a dysfunctional immune system that increased melanin production. However, longitudinal studies may contribute to a better understanding of this phenomenon. Finally, a development plan was presented that could provide a reliable prediction of disease progression. To be useful in developing countries, the index should be independent of costly blood counts and viral load.     

Oral manifestations in 101 Cambodians with HIV and AIDS.

BACKGROUND: The HIV/AIDS epidemic in Cambodia has become a major problem in the last 7-8 years, mainly because in this formerly war-stricken country the socioeconomic situation is only slowly improving. Since only very few studies have been published to date on the oral health status of Cambodian HIV/AIDS patients, it was the purpose of the present investigation to study oral manifestations in Cambodian patients with HIV disease. METHODS: One hundred one Cambodian patients with HIV infection or AIDS were examined for the presence of oral manifestations in one medical center in Phomh Penh, Cambodia. RESULTS: Sixty-three men and 38 women with a median age of 32 years were examined (age range 7.5-63.5 years). Of these patients, 42.6% were smokers, 46.5% of men were heavy drinkers and 90.5% of men were promiscuous compared with 5.3% of women. The most frequent AIDS-defining diseases were wasting syndrome (54.5%), Pneumocystis carinii pneumonia (PcP) (19.8%) and tuberculosis (18.8%). Puritic papular eruption, a common cutaneous manifestation in HIV-infected patients, was seen in 17.8% of patients. Candida-associated infections of the oral cavity were most common. Among the patients, 52.5% revealed pseudomembranous candidiasis and 35.6% had bilateral hairy leukoplakia. Only 10% of patients had no oral lesions. Also common were necrotising ulcerative gingivo-periodontal diseases (27.7%). CONCLUSION: The general health status of 101 Cambodian patients with HIV infection and AIDS was poor, and they demonstrated a large number of oral manifestations. Antiretroviral therapy is presently not available and only a fraction of patients receives antimycotic treatment (25.7%). HIV infection and the AIDS epidemic in Cambodia have become a serious problem and patients urgently need adequate diagnosis and antiretroviral therapies.
