ABSTRACT

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.

ABSTRACT

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").

ABSTRACT

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.

ABSTRACT

OBJECTIVE: Oral hairy leukoplakia (OHL) is a benign Epstein-Barr virus infection typically presenting as a white lesion on the lateral border of the tongue. Historically, OHL was described in patients who are severely immunocompromised, such as those with HIV/AIDS and organ transplant patients. OHL is increasingly seen in patients who are not severely immunocompromised. This study reviews 45 cases of OHL in a single institution and characterizes the clinical features of these relatively immunocompetent patients. STUDY DESIGN: Retrospective study. RESULTS: There were 45 cases with 23 male patients (51.1%) and a median age of 64 (range, 24-100 years). The lateral/ventral tongue was the affected site in 41 cases (91.1%), and 5 cases presented bilaterally. A review of the medical history and medications showed the most common conditions were hypertension (53.3%), hyperlipidemia (42.2%), and chronic respiratory conditions (33.3%); 8 patients (17.8%) had diabetes mellitus, and 1 had rheumatoid arthritis. Eleven cases (24.4%) reported no underlying medical conditions or history of medications. The most frequently reported medications included antihypertensive drugs (21.0%), steroid inhalers (14.6%), and cholesterol-lowering drugs (11.0%). CONCLUSIONS: OHL is not exclusively seen in profoundly immunocompromised patients. Localized immunosuppression (from steroid inhalers) and immunosenescence (aging) are possible contributing factors.

ABSTRACT

Oral hairy leukoplakia (OHL) is an Epstein-Barr virus (EBV) related lesion seen in severely immunocompromised patients especially, those with concomitant human immunodeficiency virus (HIV) infection. It has been rarely reported in immunocompetent patients. OHL most often presents on the lateral border of the tongue as an asymptomatic, white, and corrugated plaque that does not rub off. With Institutional Review Board (IRB) approval, the University of Florida Oral & Maxillofacial Pathology Biopsy Service archives spanning 1994-2020 were queried. All cases of OHL affecting immunocompetent patients were identified. Data related to age, gender, clinical presentation, results of Epstein-Barr virus in situ hybridization (EBER-ISH), and periodic acid-Schiff (PAS)-fungus stains were recorded. Medical history and histology of all cases were reviewed for confirmation of diagnosis. A total of 11 cases were identified, the majority of which were males (63.6%) with a mean age of 62 years. All patients were Caucasian. Lesions entirely were located on the lateral borders of the tongue. OHL should not be considered pathognomonic for HIV infection and should be included in the differential diagnoses of keratotic lesions affecting the lateral border of tongue even in immunocompetent elderly patients. The etiology of OHL in this group of patients is not clearly understood.

ABSTRACT

We present three cases of oral hairy leukoplakia (OHL) in whom the diagnosis was established by EBV DNA detection in whole saliva. Three HIV-infected patients came to the Oral Medicine Clinic with similar chief complaints of asymptomatic white lesions on the tongue. All patients were diagnosed with suspected OHL and oral thrush also in the first patient. A multiplex PCR DNA microarray was performed to detect EBV DNA in saliva collected by spitting method. All saliva samples showed positive results for EBV DNA, and the definitive diagnosis of OHL was made. Resolution of lesions was found at 1- to 2-month follow-up after treatment with application of acyclovir 5% cream 5 times daily. Additionally, anti-fungal treatment was given to the first patient and anti-retroviral treatment to the first and second patients. EBV is mostly transmitted by asymptomatic shedding into saliva. Therefore, the detection of salivary EBV DNA is useful in establishing a definitive diagnosis of OHL allowing more effective treatment for both HIV-infected patients receiving ART and treatment-naïve patients at any CD4 + count.

ABSTRACT

The significance of the oral manifestations of HIV has been widely recognised since the start of the epidemic. It is estimated that more than 38 million people are living with HIV currently, with more than a third presenting with oral manifestations. Access to optimum clinical management and effective treatment in resource-rich countries has led to a remarkable decrease in some of the oral manifestations in the HIV population but this is not mirrored in developing countries, where most HIV-positive patients reside. In this paper, a review of the literature since the start of the HIV infection in different parts of the world is presented to highlight the current significance of the oral conditions in this population. Oral candidiasis was repeatedly reported as the most encountered oral manifestation of HIV in different countries, including in studies on groups on anti-retroviral therapy. Over time salivary gland disease was reported less in developed countries but was encountered more in developing countries. There is evidence to show that the prevalence of oral warts increased with the establishment of anti-retroviral therapy. A review of the worldwide prevalence of HIV-related oral conditions indicates that except for oral hairy leucoplakia, the prevalence of all other nine commonly reported oral conditions remained the same or increased over time. Oral opportunistic infections in HIV-infected patients are an ongoing clinical burden mainly in developing countries. Maintaining research in the subject and improving access to HIV treatment will help address the oral health inequalities around the world.

ABSTRACT

OBJECTIVE: To review the existing research literature on the paradigm that the oral lesions could be an indicator of the disease severity with the objective of documenting the current status of research, highlighting its major findings. MATERIAL AND METHODS: Publications were identified through a careful search, of which a majority focused on oral lesions as an indicator for HIV progression. A PubMed journal search of 10 years OF period publication (2009-2019) for "oral lesion, oral manifestation, indicator, HIV and HIV-associated" was performed and analysed. Various research methods were included within the study criteria including clinical study, clinical trial, comparative study and randomised control trial. RESULTS: A total 33 studies were obtained and analysed, including cohort study, cross-sectional study, case-control study, clinical trial, retrospective observational analysis study, prospective observational study and randomised control trial. The most common oral lesions found in the studies were Kaposi sarcoma (KS), followed by oral candidiasis, periodontitis, necrotising ulcerative gingivitis (NUG), necrotising ulcerative periodontitis (NUP) and oral hairy leucoplakia (OHL). The early diagnosis and accurate treatment plan were very important to indicate the disease severity related to HIV infection. CONCLUSION: Oral lesions reported in 39% articles and could be an indicator of HIV disease severity due to its effects on decreased cluster-differentiated (CD4+) T-cell count and increased viral load.

ABSTRACT

We report a case of atypical oral hairy leukoplakia (OHL) in a 9-year-old immunocompetent girl treated with fluticasone propionate nasal spray for allergic rhinitis. The OHL in childhood is uncommon and should be included in a differential diagnosis of white lesions in the oral mucosa.

ABSTRACT

BACKGROUND: Because of reduced mortality, patients with HIV are living longer and presenting with chronic diseases. Little is known about racial differences in dermatologic conditions associated with HIV infection. OBJECTIVE: This study examines associated dermatologic conditions in a large population of patients with HIV at a tertiary care center with a diverse patient population. METHODS: Cross-sectional study of patients with HIV seen between July 14, 2013, and July 14, 2018, in a tertiary health care system. The burden of HIV-related dermatologic conditions was collected by using medical records. Patients with HIV were compared with control individuals of the same race, and significance was assessed using the chi-square test. A Bonferroni correction was performed to control for multiple hypothesis testing. RESULTS: The study population (N = 4679) was 64.7% male and 69% African American, with 88.7% of patients receiving antiretroviral therapy. African American patients with HIV had a greater risk of oral hairy leukoplakia (odds ratio [OR], 64.49), herpes zoster (OR, 9.27), prurigo nodularis (OR, 8.80), and squamous cell carcinoma (OR, 5.72). LIMITATIONS: Our data describe patients seen by 1 health care system. CONCLUSIONS: African American patients with HIV may be at increased risk for pruritic disorders compared with race-matched control individuals and white patients with HIV.

ABSTRACT

BACKGROUND: Oral hairy leukoplakia (OHL) is caused by the Epstein-Barr virus (EBV) and usually presents in patients with human immunodeficiency virus (HIV) infection and systemic immunosuppression. It is rarely seen in patients who are immunocompetent. It is clinically characterised as an asymptomatic, soft, white and corrugated lesion that cannot be scraped from the surface it adheres to. METHODS: Immunocompetent patients with OHL attending Bristol Dental Hospital within the last 6 months were identified. EBV infection was demonstrated using EBV in situ hybridization. Clinical features and medical history were determined by reviewing medical records. CASE REPORT: Four cases of OHL in immunocompetent individuals were identified. All lesions were located on the lateral borders of the tongue. DISCUSSION: OHL should be considered as a differential diagnosis for white patches on the lateral borders of the tongue in apparently healthy immunocompetent patients, even when they do not have a typical corrugated appearance. OHL should no longer be regarded as pathognomonic for HIV infection or systemic immunosuppression.

ABSTRACT

The purpose of the present study paper was to review the reported prevalence of the oral manifestations of HIV (OM-HIV) worldwide since 1980, and to determine the global variation in its prevalence over time. PubMed, Scopus, Embase and Google Scholar were searched. The filter "English" was used. The timeframe searched was 1980- 2015. The PRISMA flow chart was used. Data were extracted using the Joanna Briggs Institute standardized data extraction form and transferred to SPSS version 22 for analysis. The systematic review of 97 studies (70 low bias risk) showed that the prevalence of OM-HIV continue to be significant in developing countries. Globally and through all the decades, oral candidiasis remained the most commonly encountered OM-HIV, including among patients on antiretroviral therapy (ART) (26.2%). Hairy leukoplakia was more prevalent in Europe and America compared with Africa and Asia. Oral warts were reported more often in studies on patients receiving ART. Interestingly, salivary gland disease decreased in the developed world and increased in developing countries over time. Despite the changing pattern of these conditions over time, there is no evidence that the OM-HIV have become of less significance globally. Maintaining the drive for high-quality research in the subject will have an impact on less developed countries to help address oral health inequalities.

ABSTRACT

OBJECTIVE: We report here the 10-year experience with oral hairy leukoplakia (OHL) at the Division of Oral and Maxillofacial Pathology at the University of North Carolina at Chapel Hill, NC, USA. STUDY DESIGN: All the associated hematoxylin and eosin and Epstein-Barr virus encoding region in situ hybridization slides of OHL cases between January 1, 2008, and February 1, 2017, were retrieved and reviewed. Collected demographic characteristics, clinical presentation, medical and social histories were reviewed and reported. RESULTS: Six OHL cases with confirmed in situ hybridization showed predilection for the lateral tongue. The study included 3 females and 3 males (mean age 50.5 years; age range 29-70 years). One patient had known HIV-positive status before biopsy was performed. Three patients had reported a history of heavy smoking. Other medical conditions reported were history of breast cancer, a long history of corticosteroid inhaler use for asthma treatment, high cholesterol, diabetes, and hypertension. CONCLUSIONS: The findings of this study indicate the need to include OHL as a potential entity in the differential diagnosis of leukoplakic tongue lesions, regardless of the patient's HIV status. In addition, the presence of OHL in the patient requires investigation of various explanations for EBV infection, including immunosuppression caused by HIV infection or chronic steroid use.

ABSTRACT

OBJECTIVES: Oral hairy leukoplakia (OHL) is caused by Epstein-Barr virus (EBV) and is often associated with HIV and other immunosuppressive conditions. It is rare in HIV-negative patients, but has been reported in patients who use immune-modulating medications (e.g., cyclosporine). The objectives of this study were to determine the occurrence of OHL in HIV-negative patients and report Langerhans cell counts in these lesions. STUDY DESIGN: A series of 7 new cases of OHL among HIV-negative patients is described. Langerhans cells were counted using an immunoperoxidase stain for CD1a and light microscopy. RESULTS: The 7 patients were male, ranging in age from 26 to 69 years. Clinically, all lesions were diagnosed as leukoplakia on the lateral border of the tongue. Microscopic examination revealed hyperparakeratosis and candidiasis in some cases, acanthosis and a band-like zone with clearing of cells in the upper spinous layer, which were EBV-positive by in-situ hybridization. There was a significant decrease in Langerhans cell counts in OHL patients. CONCLUSION: OHL can occur in HIV-negative patients.

ABSTRACT

Epstein-Barr virus (EBV) is a ubiquitous gamma-herpesvirus that establishes a lifelong persistent infection in the oral cavity and is intermittently shed in the saliva. EBV exhibits a biphasic life cycle, supported by its dual tropism for B lymphocytes and epithelial cells, which allows the virus to be transmitted within oral lymphoid tissues. While infection is often benign, EBV is associated with a number of lymphomas and carcinomas that arise in the oral cavity and at other anatomical sites. Incomplete association of EBV in cancer has questioned if EBV is merely a passenger or a driver of the tumorigenic process. However, the ability of EBV to immortalize B cells and its prevalence in a subset of cancers has implicated EBV as a carcinogenic cofactor in cellular contexts where the viral life cycle is altered. In many cases, EBV likely acts as an agent of tumor progression rather than tumor initiation, conferring malignant phenotypes observed in EBV-positive cancers. Given that the oral cavity serves as the main site of EBV residence and transmission, here we review the prevalence of EBV in oral malignancies and the mechanisms by which EBV acts as an agent of tumor progression.
