RESUMEN
BACKGROUND: This study evaluated the presence of Epstein-Barr virus type 1 (EBV-1) DNA in patients living with HIV, before and after three different topical therapy protocols for oral hairy leukoplakia (OHL). METHODS: The sample consisted of five patients treated with topical solution of 25% podophyllin resin; six with 25% podophyllin resin plus 5% acyclovir cream; and four with 25% podophyllin resin plus 1% penciclovir cream. DNA was extracted from OHL scrapings and amplified by the PCR using specific primers for EBV-1 (EBNA-1). RESULTS: Clinical healing of OHL lesions was observed across all treatment groups over time. At baseline, EBNA-1 was detected in all OHL lesions. After treatment, OHL samples from three patients treated with 25% podophyllin resin plus 5% acyclovir cream and from one patient treated with 25% podophyllin resin plus 1% penciclovir cream exhibited negative EBNA-1 viral gene encoding. Despite the clinical resolution of OHL, 11 patients (73.3%) showed EBNA-1 positivity immediately after the lesion disappeared. Three patients (20%) treated with podophyllin resin displayed both EBNA-1 positivity and a recurrence of OHL, in contrast to no recurrence in the other two groups. CONCLUSIONS: These findings suggest potential associations between treatment formulations, EBNA-1 persistence, and the recurrence of OHL lesions.

OBJECTIVE: The aim of this study was to assess the prevalence of orofacial manifestations in a Brazilian cohort of people living with HIV/AIDS (PLWHIV) using long-term combined antiretroviral therapy (cART) and to correlate the presence of these manifestations with clinical and laboratory characteristics. STUDY DESIGN: A cross-sectional observational study evaluated 101 Brazilian PLWHIV. Demographic characteristics, medical history, and laboratory data were collected. Physical examination and measurement of stimulated salivary flow were performed. RESULTS: The study included 101 participants who were mainly male (61%) and White (73%), with an average age of 48 years, using long-term cART. The most common oral manifestations were facial lipoatrophy (33%), xerostomia (30%), and salivary gland enlargement (12%). Facial lipoatrophy was linked to a longer duration of cART use (P = .002), whereas hairy leukoplakia was linked to a detectable viral load (P = .031). The salivary flow of <0.7 mL/min was associated with an HIV infection time >20 years (P = .023). CONCLUSIONS: People living with HIV/AIDS who use cART often experience facial lipoatrophy, xerostomia, and bilateral enlargement of the parotid glands. Although opportunistic infections and malignant neoplasms are not frequent occurrences, they can still arise.

OBJECTIVES: This study aimed to assess the prevalence of oral lesions in patients living with HIV infection and their association with CD4 count, viral load, and antiretroviral therapy in patients with HIV. METHODS: A cross-sectional study was conducted on a sample of 161 patients attending the All the patients were examined for their oral lesions, current CD4 counts, type, and duration of the therapy. Data analyses were carried out using Chi-Square, Student T/Mann-Whitney, and logistic regression tests. RESULTS: Oral lesions were observed in 58.39% of patients with HIV. Periodontal disease with 78 (48.45%) or without mobility 79 (49.07%) was observed more frequently, followed by hyperpigmentation of oral mucosa 23 (14.29%), Linear Gingival Erythema (LGE) 15 (9.32%), candidiasis pseudomembranous 14 (8.70%). Oral Hairy Leukoplakia (OHL) was observed only in 3 (1.86%). A relationship between periodontal disease with dental mobility and smoking was found (p=0.04), as well duration of treatment (p=1.53e-3) and age (p=0.02). Hyperpigmentation was related to race (p=0.01) and smoking (p=1.30e-6). CD4 count, CD4:CD8 ratio, viral load, or type of treatment were not associated with oral lesions. Logistic regression showed that the duration of treatment has a protective effect on the periodontal disease with dental mobility (OR = 0.28 [-2.27 to -0.25]; p-value=0.03), independent of age or smoking. To hyperpigmentation, the best model included smoking (OR=8.47 [1.18-3.10], p= 1.31e-5), without race or type and duration of treatment. CONCLUSION: Among HIV patients undergoing antiretroviral treatment, oral lesions can be observed, predominantly periodontal disease. Pseudomembranous candidiasis and oral hairy leukoplakia were also observed. No relationship was found between associated oral manifestations in HIV patients and the start of the treatment, TCD4+ and TCD8+ cell count, TCD4:TCD8 ratio, or viral load. The data indicate that there is a protective effect of duration of treatment with relation to periodontal disease with mobility and that hyperpigmentation seems to be more related to smoking than type and duration of treatment. LEVEL OF EVIDENCE: Level 3 (OCEBM Levels of Evidence Working Group*. "The Oxford 2011 Levels of Evidence").

OBJECTIVE: To assess the oral shedding and viremia of Epstein-Barr virus (EBV) in HIV-positive patients and their relationship with oral hairy leukoplakia (OHL). METHODOLOGY: A total of 94 HIV-positive patients were included in the study, in which blood and saliva samples were collected for EBV quantification. Data on gender, age, time of HIV seropositivity, combined antiretroviral therapy (cART), CD4+ T-cell counts, and HIV viral load were collected. OHL diagnosis was based on histopathological examination and EBV in situ hybridization. RESULTS: The EBV load in the 94 HIV-positive patients was higher in saliva than in blood (2.4 and 1.6, respectively), and there was a positive correlation between EBV oral shedding and viremia (p = 0.001). Twenty (21.27%) patients had OHL and also a higher EBV load in saliva (mean log10 = 3.11) compared to those who had no OHL (p = 0.045). Presence of OHL was only associated with age (p = 0.030). CONCLUSION: In HIV-positive patients, the presence of OHL was associated with EBV oral shedding but not with viremia, regardless of the amount of circulating CD4+ T cells.

Oral manifestations are common findings in human immunodeficiency virus (HIV) infected patients and frequently influence the overall health. Oral hairy leukoplakia (OHL) is strongly associated with HIV infection demonstrating its relationship with the individual's immune status and progression of immunosuppression. This study aims to retrospectively evaluate OHL in HIV patients, analyzing its incidence, demographic aspects and possible changes in clinical and epidemiological profile of the disease over 17 years. The records of 1600 HIV-infected patients were reviewed. The data were correlated and analyzed, considering HIV exposure category, age, gender, harmful habits, CD4 level, use and type of antiretroviral. OHL was observed in 215 (13.4%) patients. Most were men in the fourth decade of life, 171 (79.5%) and 112 (52,1%) respectively, but an increase in the incidence of OHL among female patients and those in the fifth decade of life was observed. Tobacco smoking was the most frequent harmful habit reported by 114 (68%) patients. OHL occurred mostly in patients with CD4 counts between 200 and 500 cells/mm3 35 (55.5%). The lower incidence of OHL was found among patients using at least one non-nucleoside reverse transcriptase inhibitor (NNRTI). OHL is related to CD4 count, use of ARVT and tobacco smoking and is also more prevalent in men in the fourth decade of life. These characteristics were recognized in absolute values, but when verifying the behavior over the years we noticed that the incidence of OHL is decreasing and its epidemiological characteristics changing.

Introdução: As lesões bucais e peribucais são comuns nos pacientes infectados pelo vírus HIV e podem representar os primeiros sinais da doença, antes mesmo das manifestações sistêmicas. Objetivo: Este estudo objetivou estimar a prevalência de manifestações bucais em indivíduos soropositivos para o HIV, considerando aspectos sociodemográficos, imunológicos e terapêuticos. Material e Método: Foi realizado um estudo de natureza clínico-epidemiológica transversal, entre outubro de 2007 e abril de 2008, com amostra composta por 40 pacientes. Utilizou-se a técnica de observação direta intensiva por meio de exame clínico apropriado. Os dados foram registrados em fichas pré-elaboradas e analisados por estatística descritiva e inferencial. Resultado: Verificou-se a prevalência do gênero feminino (52,5%), na faixa etária de 40 a 49 anos (45%). O tratamento com antirretrovirais foi constatado em 85,0% dos casos, sendo todos com terapia de alta potência (HAART). Observou-se que 52,5% dos pacientes apresentaram a contagem de linfócitos TCD4+ acima de 500cél/mm³ e 50,0% apresentaram carga viral indetectável. A prevalência das manifestações bucais foi 42,5%, sendo a mais expressiva a candidose pseudomembranosa (19,23%), seguida da periodontite úlcero-necrosante (15,38%), da leucoplasia pilosa (11,54%) e da queilite angular (11,54%). Não foi verificada associação entre manifestações bucais e carga viral (p=0,1268), nem com o número de células T CD4 (p=0,3458). Conclusão: A prevalência de algumas manifestações bucais associadas à infecção pelo HIV ainda é alta, sendo a candidose pseudomembranosa a infecção mais prevalente, principalmente entre pessoas com baixo nível ...
Introduction: The oral and perioral lesions are common in patients infected with HIV, and may represent the first signs of the disease, even before the systemic manifestations. Objective : This study aimed to estimate the prevalence of oral manifestations in HIV seropositive individuals, considering the aspects socio-demographic, immunological and therapeutic. Material and Method: Was performed nature study clinical-epidemiological transverse, between October 2007 to April 2008, with a sample of 40 patients. Was used the technique of intensive direct observation through appropriate clinical exam. Data were recorded on data sheets pre-prepared and analyzed by descriptive and inferential statistics. Result: There was a prevalence of females (52.5%), aged 40-49 years (45%). Treatment with antiretroviral drugs was found in 85.0% of cases, all being with high power therapy (HAART). It was observed that 52.5% of patients had a TCD4+ lymphocyte count above 500cél/mm ³ and 50.0% had an undetectable viral load. The prevalence of oral manifestations was 42.5%, the most significant for pseudomembranous candidiasis (19.23%), followed necrotizing ulcerative periodontitis (15.38%), hairy leukoplakia (11.54%) and angular cheilitis (11.54%). No association was observed between oral lesions and viral load (p=0.1268) nor the TCD4 cell count (p=0.3458). Conclusion: Prevalence of some oral manifestations associated with HIV infection is still high, with pseudomembranous candidiasis infection more prevalent, mainly among people with low education levels and longer HIV infection, independent of the therapy and immune status of the patient. .

OBJECTIVE: To establish a definitive diagnosis of oral hairy leukoplakia (OHL) by in situ hybridization for Epstein-Barr virus (EBV) detection with liquid-based cytology (LBC), using the ThinPrep® Pap Test, and to compare its efficacy with the traditional method of performing biopsy. METHODS: Thirty-three individuals divided into three groups were included in this study. Group 1 consisted of 15 human immunodeficiency virus (HIV)-positive patients with a clinical and histopathological diagnosis of OHL on the lateral border of the tongue. Group 2 consisted of 10 HIV-positive individuals with neither OHL nor other oral lesions. Group 3 consisted of 10 immunocompetent HIV-negative individuals with neither OHL nor other oral lesions. For each patient from the three groups, exfoliative LBC was performed on the lateral border of the tongue using ThinPrep. For the patients from group 1, a 6-mm-diameter punch biopsy was obtained from the same anatomic site as the brush collection to confirm the diagnosis of OHL by histopathology with in situ hybridization. Slides were prepared for morphological cellular analysis using Papanicolaou (Pap) staining, and for EBV detection using in situ hybridization. RESULTS: Thirteen of the 15 patients from group 1 were confirmed on punch biopsy as OHL, providing the gold standard for the study. The sensitivity of LBC followed by a Pap-stained smear was 62% and the specificity was 90%. The sensitivity of LBC followed by in situ hybridization was 100% and the specificity was 100%. CONCLUSIONS: Exfoliative LBC associated with EBV in situ hybridization is a simple, effective and non-invasive diagnostic tool for OHL.

AIM: The purpose of this study was to compare gender differences in the prevalence of oral lesions in HIV-infected Brazilian adults. METHODOLOGY: A retrospective study was conducted of medical records from HIV/AIDS patients from 1993 to 2004. Oral lesions were only included in this study if definitively diagnosed through microscopic analysis, therapeutic test or according to EC-Clearing house criteria. RESULTS: A total of 750 men and 237 women were included in the study. Statistically significant differences were observed only for oral hairy leukoplakia, Kaposi sarcoma and lymphadenopathy (P < 0.01). However, a model of logistic regression showed that only oral hairy leukoplakia presented a significant association with gender and males had a significantly likelihood (four times higher than females) of presenting with this oral manifestation [OR 4.3 (95% CI: 1.39-13.36)]. CONCLUSION: These data shows that oral manifestations are less prevalent in females than in males, particularly oral hairy leukoplakia.

Oral lesions are common in human immunodeficiency virus (HIV)-infected patients, which may indicate impairment of the patient's general health status, and, in many cases, the oral lesions are the first sign of an HIV infection. Oral hairy leukoplakia (OHL) is a benign lesion of the oral mucosa related to Epstein-Barr virus (EBV) observed in HIV-positive individuals. The aim of this study was to report the contribution of oral cytopathology in the investigation of the HIV/AIDS status of patients as well as in the clinical and subclinical identification of OHL. Three patients were referred to the Oral Medicine Clinic in 2010. The patients were submitted to oral examination, and scrapes of the tongue were obtained. The Papanicolaou staining technique was used, and cytopathological analysis showed nuclear changes corresponding to cytopathic effects of EBV epithelial infection and candidiasis. The final diagnosis was OHL and candidiasis. Based on cytopathological diagnosis, an HIV serologic test was requested which revealed positive HIV serology. None of the patients was aware of their HIV serological status, and thus the cytopathology, by identifying OHL, contributed to the early diagnosis of HIV/AIDS. Cytopathology should be used as a routine procedure and it may be the method of choice for clinical and subclinical OHL diagnosis.

AIMS: To quantify and compare the expression of Langerhans cells (LCs) in the tongue mucosa of AIDS patients with different opportunistic infections, and from acquired immune deficiency syndrome (AIDS) and non-AIDS patients with normal tongues, using autopsy material. METHODS AND RESULTS: Human leucocyte antigen D-related (HLA-DR), CD1a and CD83 antibodies were used to identify and quantify LCs by immunohistochemistry in tongue tissue of 40 AIDS patients (10 with lingual candidiasis, 10 with lingual herpes, 10 with oral hairy leukoplakia and 10 with no lesions) and 23 tongues from human immunodeficiency virus (HIV)-negative control patients. Quantification was performed by means of conventional morphometry in four different regions (anterior, middle, posterior and lateral) of the tongue. The results were expressed as positive cells per area of epithelium. The AIDS patients presented a lower density of CD1a(+) cells (P < 0.001), HLA-DR (P < 0.003) and CD83 (P < 0.001) in all regions of the tongue compared to the non-AIDS control group. However, no differences in any of the markers were found when AIDS patients with different opportunistic infections were compared with AIDS patients without tongue infection. CONCLUSIONS: Advanced stage AIDS patients showed a depletion of LCs in the tongue mucosa. HIV infection induces cytopathic changes in LCs, contributing to their depletion regardless of the presence of oral infections.

We estimated the prevalence of oral lesions associated with human immunodeficiency virus (HIV-OLs) before and during the antiretroviral therapy (ART) era. The first period was 1997, when many patients received two types of antiretroviral (ARV) drugs. The second study period was 2004 through 2008, when all patients were treated with ART (a combination of two or three classes of drugs, including protease inhibitors). A total of 148 and 388 seropositive participants were examined in 1997 and 2004-2008, respectively. The evaluation consisted of anamnesis and physical examination. The prevalence of HIV-OLs decreased between 1997 (60.1%) and 2004-2008 (29.9%). The HIV-OL responsible for the greatest reduction in prevalence between the two periods was oral candidiasis, of which erythematous candidiasis was the clinical form that decreased most, followed by pseudomembranous candidiasis. In conclusion, we observed a significant reduction in HIV-OLs, which was closely associated with the use of ART. In addition, among patients with a clinical diagnosis of AIDS, we confirmed a significant reduction in HIV-OL prevalence between 1997 and 2004-2008.

Oral hairy leukoplakia (OHL) is commonly found in individuals infected with HIV and represents the most frequent oral manifestation. The purpose of this study was to detect the presence of Human Papillomavirus (HPV) and Epstein Barr Virus (EBV) in OHL of HIV+ Venezuelan patients. We evaluated 21 HIV+ adult patients with clinically present OHL lesions: 11 under antiretroviral therapy, 10 without therapy, and 10 oral mucosal samples as controls. Nested-PCR was used to detect EBV and HPV infection. The INNO-LiPA HPV Genotyping v2 was applied to determine the HPV genotype. The EBV genome was found in 16/21 (76%) of the HIV+ patients with OHL. No difference was observed in EBV+ and EBV- patients related to antiretroviral therapy viral load and CD4+ Tcell coant. HPV-DNA was observed in 7/21 HIV positive cases (33%). The HPV genotypes detected were: 6, 11, 31, 33, 52, and 56/74. The most frequently HPV found was genotype 6 in 7/7, while two cases were HPV-11 and two HPV-52. Of the positive cases, 5/7 (71%) presented co-infection with more than one HPV genotype and 4/7 (57%) had HPV coinfection with high and low risk types. No case was EBV or HPV positive in the control group. In this study, a higher EBV prevalence was observed in OHL-HIV+ patients, confirming the etiologic role in this entity. A considerable number of cases were positive for HPV infection, and many patients presented coinfection with more than one HPV genotype as well as the presence of high oncogenic risk HPV in OHL.

OBJECTIVE: The aim of this study was to present a new topical treatment protocol for oral hairy leukoplakia (OHL), consisting of a 25% podophyllin resin with a 1% penciclovir cream (PP), and to compare this topical treatment protocol's efficacy with that of 2 other topical treatment protocols: a 25% podophyllin resin (P) and a 25% podophyllin resin with a 5% acyclovir cream (PA). STUDY DESIGN: Forty-two human immunodeficiency virus-positive patients with 69 OHL lesions were randomly treated using P, PA, or PP (14 patients in each topical treatment protocol). Clinical healing was determined when the white plaque could no longer be seen in the primary location of the lesion. Topical treatment performance was evaluated by clinical healing within each week of topical treatment protocol as well as by the recurrence of the lesion. Statistical survival analysis was performed using a Cox proportional hazards model. RESULTS: Approximately 55% of the patients presented with clinical healing of OHL within 7-8 weeks of each topical treatment protocol. After the sixth week, the PA treatment protocol presented a faster clinical healing rate of OHL. Recurrence was observed in 3 and 7 OHL lesions treated with P and PP treatment protocols, respectively. CONCLUSIONS: The PP treatment protocol proved to be effective; however, the PA treatment protocol was more effective in the clinical healing rate for OHL than P and PP after the sixth week of treatment, and no recurrent OHL was observed in the PA treatment group.

Oral hairy leukoplakia (OHL) is commonly found in individuals infected with HIV, and represents the most frequent oral manifestation. The purpose of this study was to detect the presence of Human Papillomavirus (HPV) and Epstein Barr Virus (EBV) in OHL of HIV+ Venezuelan patients. We evaluated 21 HIV+ adult patients with clinically present OHL lesions: 11 under antiretroviral therapy, 10 without therapy, and 10 oral mucosal samples as controls. Nested-PCR was used to detect EBV and HPV infection. The INNO-LiPA HPV Genotyping v2 was applied to determine the HPV genotype. The EBV genome was found in 16/21 (76%) of the HIV+ patients with OHL. No difference was observed in EBV+ and EBV- patients related to antiretroviral therapy viral load and CD4+ T cell count. HPV-DNA was observed in 7/21 HIV positive cases (33%). The HPV genotypes detected were: 6, 11, 31, 33, 52, and 56/74. The most frequently HPV found was genotype 6 in 7/7, while two cases were HPV-11 and two HPV-52. Of the positive cases, 5/7 (71%) presented co-infection with more than one HPV genotype and 4/7 (57%) had HPV coinfection with high and low risk types. No case was EBV or HPV positive in the control group. In this study, a higher EBV prevalence was observed in OHL-HIV+ patients, confirming the etiologic role in this entity. A considerable number of cases were positive for HPV infection, and many patients presented coinfection with more than one HPV genotype as well as the presence of high oncogenic risk HPV in OHL.
El proposito del presente estudio fue detectar la presencia de virus papiloma humano (VPH) y Epstein Barr (VEB) en Leucoplasia Vellosa Oral (LVO) de pacientes VIH positivos. Se evaluaron 21 pacientes adultos VIH positivos con lesiones clinicas presentes de LVO y 10 casos controles de mucosa sana. Para el diagnostico molecular de VPH y EBV se utilizo Nested PCR. La determinacion de los genotipos se realizo mediante el kit HPV INNO-LiPA genotyping v2. La presencia de genoma de VEB se demostro en un alto porcentaje (76%) en 16/21 de los pacientes VIH positivos con LVO. No se observo relacion entre los pacientes VEB+ y VEBcon el uso de terapia antirretroviral, la carga viral y el contaje de celulas T CD4+. Se demostro la presencia de ADN-VPH en 7/21 (8%) de los casos VIH positivos. Los genotipos de VPH detectados fueron 6, 11, 31, 33, 52, 56/74. El genotipo 6 fue el mas frecuentemente observado en 7/7, dos casos fueron VPH 11 y dos VPH 52. De los casos positivos 5/7 (71%) presentaron coinfeccion con mas de un genotipo de VPH y en 4/7 (57%) se evidencio coinfeccion con tipos de alto y bajo riesgo oncogenico. En el presente estudio se observo una alta prevalencia de VEB en pacientes VIH positivos con LVO, confirmando el papel etiologico en esta entidad. Un considerable numero de casos fueron positivos para VPH. Se observo la presencia de coinfeccion con mas de un tipo viral, asi como la presencia de VPH de alto riesgo.

Introdução: Pacientes com imunosupressão pela infecção do HIV (Human Immunodefi ciency Vírus) freqüentemente desenvolvem lesões de boca como a leucoplasia pilosa (LP). LP é uma lesão quase que exclusivamente observada em indivíduos infectados pelo HIV que apresentam uma baixa contagem de linfócitos T CD4. LP é assintomática e aparece como placa branca na borda lateral da língua, de superfície plana, corrugada ou pilosa e não removível quando raspada. A etiologia da LP é relacionada ao vírus Epstein-Barr, que pode ser identificado através de técnicas de microscopia eletrônica, hibridização "in situ", imunoistoquímica e reação em cadeia da polimerase. A citologia esfoliativa é uma boa opção para o diagnóstico da LP, por ser um método simples, confiável, seguro, não invasivo e não traumático. O tratamento da LP é recomendado para eliminar as pilosidades, restaurar o conforto do paciente, re-estabelecer as características normais da língua e eliminar nichos de bactérias, vírus e fungos desencadeadores de outras doenças da boca. Os tratamentos propostos na literatura para LP incluem cirurgia, terapia anti viral sistêmica e a terapia tópica. Objetivo: Realizar uma revisão de literatura sobre as opções de tratamento para a LP. Conclusão: A terapia tópica tem sido a mais recomendada, por ser de fácil aplicação, pouco invasiva, de baixo custo, com poucos efeitos colaterais e, principalmente, para eliminar as pilosidades e EBV, para restabelecer as características normais da língua sem desenvolvimento de resistência aos vírus e para eliminar nichos bacterianos e fúngicos. Indicações clínicas para esse tratamento devem incluir sintomas associados à lesão ou um desejo do paciente, por razões estéticas de eliminar a lesão.
Introduction: Patients with immunosupression caused by the human immunodeficiency virus (HIV) infection frequently develop oral lesions such as oral hairy leukoplakia (OHL). OHL is a lesion almost exclusively observed in HIV-infected individuals, who present low T CD4 lymphocyte count. OHL is asymptomatic and appears as a white plaque on the lateral border of the tongue, with fl at, corrugated or hairy surface, which is not detachable when scraped. The etiology of OHL is related to Epstein-Barr virus, which may be detected by electron microscopy, in situ hybridization, immunohistochemistry, and polymerase chain reaction techniques. Exfoliative cytology is a good option for the diagnosis of OHL, for being a simple, reliable, safe, noninvasive and non-traumatic method. The treatment of OHL is recommended to eliminate the filiform structures on lesion surface, provide comfort to the patient, re-establish the normal characteristics of the tongue and eliminate possible niches for bacteria, viruses and fungi that may cause other oral diseases. The treatments proposed in the literature for OHL include surgery, anti viral systemic therapy and topical therapy. Objective: This paper presents a literature review about the treatment options for OHL. Conclusion: Topical therapy has been the most recommended because it is easy to apply, is a low-invasive and low-cost procedure, and has few side effects. It is mainly indicated for removing the filiform structures on lesion surface, eradicating the Epstein-Barr virus, reestablishing the normal characteristics of the tongue without developing resistance to the virus, and eliminating bacterial and fungal niches. Clinical indications for this treatment should include symptoms associated with the lesion or the patient's desire of eliminating the lesion for esthetic reasons.

PURPOSE: To determine the prevalence of Epstein Barr virus (EBV) in oral hairy leukoplakia lesions (OHL) in HIV+ Venezuelan patients. MATERIAL AND METHOD: In this case study, we evaluated 21 HIV+ adult patients with clinically present OHL lesions, 11 who were undergoing antiretroviral therapy, 10 who were not undergoing therapy and 10 HIV-negative adult patients with hyperkeratotic oral mucosal lesions. All of the subjects were assessed at the Infectious Disease Center, Faculty of Dentistry, Central University of Venezuela, and were clinically examined to detect oral mucosal lesions with the confirmed histopathologic diagnosis. Nested-PCR was used to determine the EBV infection and the latent membrane protein-1 (LMP-1) expression by immunohistochemistry. RESULTS: Of the subjects, 16/21 (76%) of the HIV+/AIDS patients tested positive for EBV, whereas 5/10 (50%) of the HIV-negative subjects tested positive for EBV. CONCLUSIONS: In the present study, a higher EBV prevalence was observed in HIV-positive patients when compared to HIV-negative patients without oral hairy leukoplakia, confirming the etiologic role in this entity. The LMP-1 in OHL patients who were both HIV+ and EBV+ was highly expressed (60%) at the epithelial basal cells. No association between the alcohol and tobacco consumption was observed among the EBV-positive cases.
