Oral Manifestations Associated with HIV/AIDS Patients

Oral and oropharyngeal mucosal lesions: clinical-epidemiological study of patients attended at a reference center for infectious diseases

OBJECTIVE

To determine the prevalence, epidemiological profile, and clinical characteristics of Oral or Oropharyngeal Mucosal Lesions (OOPML) in patients attended at the Otorhinolaryngology Service of the Evandro Chagas National Institute of Infectious Diseases (INI-FIOCRUZ) from 2005 to 2017.

METHODS

Statistical analysis of descriptive data from medical records (gender, age, education level, skin color, origin, smoking, alcoholism, HIV co-infection, time of disease evolution, first symptom, and OOPML location) was performed.

RESULTS

Of 7551 patients attended at the service, 620 (8.2%) were included in the study. OOPML were classified into developmental anomalies (n = 3), infectious diseases (non-granulomatous n = 220; granulomatous n = 155), autoimmune diseases (n = 24), neoplasms (benign n = 13; malignant, n = 103), and unclassified epithelial/soft tissue diseases (n = 102). OOPML of infectious diseases (60.5%) and neoplasms (18.7%) were the most frequent. The predominant demographics of patients with OOPML were: males (63.5%), white (53.5%), and those in the fifth to sixth decades of life (43.3%). Local pain (18.1%) and odynophagia (15%) were the most reported first symptoms, and the most frequent OOPML sites were the palatine tonsil (28.5%), hard palate (22.7%), and tongue (20.3%). The median evolution time was three months.

CONCLUSIONS

Infectious OOPML were the most frequent, as expected in a reference center for infectious diseases, and thus, they are likely to be less frequent in general care and/or dental services. Underreporting of OOPML is possible, as oral/oropharyngeal examination is often not included in the routine medical examination. Oral cavity/oropharynx examination should be performed by specialists, such as dentists and otorhinolaryngologists, who have the expertise in identifying OOPML, even in incipient/asymptomatic cases. Given the numerous diseases in which OOPML can present, diagnosis could be facilitated by multidisciplinary teams, potentially enabling the early treatment of diseases, and thus, reduce morbidity and improve prognosis. The use of standardized medical records for oral/oropharyngeal systematic examination could provide relevant tools for differential diagnoses and information for new clinical-epidemiological studies.

Human immunodeficiency virus and oral microbiota: mutual influence on the establishment of a viral gingival reservoir in individuals under antiretroviral therapy

The role of the oral microbiota in the overall health and in systemic diseases has gained more importance in the recent years, mainly due to the systemic effects that are mediated by the chronic inflammation caused by oral diseases, such as periodontitis, through the microbial communities of the mouth. The chronic infection by the human immunodeficiency virus (HIV) interacts at the tissue level (e.g. gut, genital tract, brain) to create reservoirs; the modulation of the gut microbiota by HIV infection is a good example of these interactions. The purpose of the present review is to assess the state of knowledge on the oral microbiota (microbiome, mycobiome and virome) of HIV-infected patients in comparison to that of HIV-negative individuals and to discuss the reciprocal influence of HIV infection and oral microbiota in patients with periodontitis on the potential establishment of a viral gingival reservoir. The influence of different clinical and biological parameters are reviewed including age, immune and viral status, potent antiretroviral therapies, smoking, infection of the airway and viral coinfections, all factors that can modulate the oral microbiota during HIV infection. The analysis of the literature proposed in this review indicates that the comparisons of the available studies are difficult due to their great heterogeneity. However, some important findings emerge: (i) the oral microbiota is less influenced than that of the gut during HIV infection, although some recurrent changes in the microbiome are identified in many studies; (ii) severe immunosuppression is correlated with altered microbiota and potent antiretroviral therapies correct partially these modifications; (iii) periodontitis constitutes a major factor of dysbiosis, which is exacerbated in HIV-infected patients; its pathogenesis can be described as a reciprocal reinforcement of the two conditions, where the local dysbiosis present in the periodontal pocket leads to inflammation, bacterial translocation and destruction of the supporting tissues, which in turn enhances an inflammatory environment that perpetuates the periodontitis cycle. With the objective of curing viral reservoirs of HIV-infected patients in the future years, it appears important to develop further researches aimed at defining whether the inflamed gingiva can serve of viral reservoir in HIV-infected patients with periodontitis.

Patient communication protocols for sexually transmitted infections: A systematic review

AIMS

We conducted a systematic review of post-test communication protocols and observational studies regarding counseling for a positive sexually transmitted infection (STI) result and also discuss the role of dental specialist (e.g., oral medicine) in this sense.

METHODS AND RESULTS

The search process followed the parameters of PRISMA 2020 guidelines. MEDLINE/PubMed, Web of Science, Scopus, EMBASE, and LILACS were consulted with a specific search strategy for each one. Additionally, the references of the included studies, grey literature, and experts were consulted. Four protocols and 18 observational studies were included in this systematic review, published between 1997 and 2022 in the Americas and Europe. The communication protocols emphasized the importance of conducting personal and private discussions with patients to address their fears and questions. Among the observational studies, 56% indicated that post-test counseling was either ineffective or absent. Furthermore, 22% of the studies used telephone communication to deliver results to patients.

CONCLUSIONS

Our study showed that the communication process of a positive STI result affects the patients in several aspects, as treatment adherence and their relationship with the community. Nevertheless, this process of STI post-test communication seems to be flawed, which brings potential negative effects to patients.

Vitamin D deficiency and oral candidiasis in patients with HIV infection: A case‒control study

BACKGROUND

Oral candidiasis is a common opportunistic infection in patients with human immunodeficiency virus (HIV). In addition, most of these patients suffer from vitamin D deficiency. This study aimed to investigate the association between vitamin D levels and oral candidiasis in patients with HIV infection.

METHODS

This case‒control study was conducted on HIV-infected patients. Cases were patients with oral candidiasis diagnosed based on physical examinations. Controls were age- and sex-matched individuals without oral candidiasis. The levels of 25-OH vitamin D and other laboratory markers (CD4 count and viral load) were compared between the case and control groups.

RESULTS

A total of 104 cases and 102 controls were included in the study. The cases had significantly lower 25-OH vitamin D3 levels (MD = 33.86 ng/mL, 95% CI= (31.85, 35.87), P < 0.001) and CD4 counts (MD = 267.48 cells/mm3, 95% CI= (189.55, 345.41), P < 0.001) than the controls. In addition, viral load was significantly higher in cases than in controls (MD = 7.03 × 105 copies/mL, 95% CI= (4.46 × 105, 9.61 × 105), P < 0.001). The multivariate logistic regression analysis revealed that educational status (OR = 0.032, 95% CI= (0.002, 0.100), P < 0.001), current HAART (OR = 0.005, 95% CI= (0.001, 0.014), P < 0.001), history of oral candidiasis (OR = 20.114, 95% CI= (18.135, 21.957), P < 0.001), CD4 count (OR = 0.004, 95% CI= (0.001, 0.006), P < 0.001), viral load (OR = 12.181, 95% CI= (1.108, 133.392), P < 0.001), and vitamin D level (OR = 0.011, 95% CI= (0.008, 0.015), P < 0.001) were significantly associated with the risk of developing oral candidiasis.

CONCLUSIONS

Based on the findings, most patients with HIV infection suffer from vitamin D deficiency, especially those with oral candidiasis. Hypovitaminosis D was significantly associated with an increased risk of oral candidiasis. Thus, vitamin D supplementation may assist HIV-positive patients in improving their oral health and preventing oral candidiasis.

HIV-Related Oral Mucosa Lesions: A Cross-Sectional Study on a Cohort of Italian Patients

BACKGROUND

Human immunodeficiency virus (HIV) infection can be associated with oral mucosal diseases, including oral candidiasis and HPV infection, which are putative indicators of the immune status.

AIM AND METHODS

This retrospective cross-sectional study was aimed at assessing the prevalence of HIV-related oral mucosal lesions in a cohort of Italian HIV+ patients regularly attending the Clinics of Infectious Diseases.

RESULTS

One hundred seventy-seven (n = 177) patients were enrolled and 30 (16.9%) of them showed HIV-related diseases of the oral mucosa. They were mainly found in male patients over 35 years old, undergoing Combination Antiretroviral Therapy (cART), and with CD4+ count < 500/µL. Oral candidiasis was the most common HIV-related oral lesion. No significant correlations could be detected between the prevalence of HPV infection and other clinical parameters (lymphocyte count, cART treatment and viral load).

CONCLUSIONS

HIV-related oral mucosal diseases can correlate with immunosuppression. Early diagnosis and management of oral lesions in HIV+ patients should be part of the regular follow-up, from a multidisciplinary perspective of collaboration between oral medicine and infectious disease specialists, in an attempt to reduce morbidity due to oral lesions and modulate antiretroviral therapy according to the patient's immune status.

The Association Between Oral Mucosal Lesions and Oral Health-Related Quality of Life Using the Validated Indonesian Version of OHIP-14 Among People Living with HIV/AIDS

Background

Oral mucosal lesions in human immunodeficiency virus (HIV) and acquired immunodeficiency syndrome (AIDS) patients, posing a concern for healthcare professionals, impact their oral health-related quality of life (OHRQoL). This study aimed to evaluate the association between oral mucosal lesions and OHRQoL as measured by the validated Indonesian version of the oral health impact profile-14 questionnaire (OHIP-14) among people living with HIV/AIDS (PLWHA).

Methods

A cross-sectional study was conducted at the Central Referral Hospital in West Java, Indonesia. The validity of OHIP-14 was evaluated in 30 PLWHA using inter-item corrected correlation, while reliability was assessed through Cronbach's alpha and kappa coefficient agreement. Subsequently, a consecutive sample of 110 PLWHA self-completed the validated Indonesian version of OHIP-14 and underwent an oral examination. The association between oral mucosal lesions and OHRQoL was analyzed using the chi-squared test.

Results

The validity test of the OHIP-14 questionnaire produced a rcount > 0.189, meaning that all question items were valid and could be used to describe OHRQoL. The reliability test of the OHIP-14 questionnaire produced a Cronbach's alpha value of 0.960 (> 0.7), which means that overall, the OHIP-14 questionnaire is reliable and feasible to be used to assess OHRQoL. Among the 110 enrolled participants, 61.8% were female and 38.2% were male, with the mean age 23.5 years old, the majority of them (59.1%) had been taking antiretrovirals (ARV), and (81.5%) had good QoL. There was a statistically significant relationship between oral lesions and quality of life (p<0.05), particularly acute pseudomembranous candidiasis, angular cheilitis, recurrent intraoral herpes, and Stevens-Johnson syndrome.

Conclusion

This study indicated a significant association between oral mucosal lesions and OHRQoL in PLWHA. The successfully validated Indonesian version of the OHIP-14 questionnaire serves as a reliable and effective tool for assessing OHRQoL among PLWHA.

Evaluation of Knowledge and Attitude of Dental Hygienists and Dental Assistants Regarding People Living with HIV/AIDS and HIV-Associated Oral and Periodontal Lesions in Jeddah, Saudi Arabia

BACKGROUND

Oral manifestations serve as important indicators of human immunodeficiency virus (HIV) infection, and dental healthcare practitioners play a pivotal role in preventing and managing HIV. This study aims to assess and compare the knowledge and attitude of dental assistants and dental hygienists concerning people with HIV/acquired Immunodeficiency syndrome (AIDS) patients in Jeddah province of Saudi Arabia.

MATERIALS AND METHODS

This cross-sectional survey enrolled 160 dental hygienists and assistants practicing in Jeddah. Data was collected using a pretested, self-administered questionnaire comprising 50 questions that investigated knowledge about HIV/AIDS, awareness of HIV-associated oral and periodontal lesions, understanding of HIV transmission routes, and attitudes toward people with AIDS.

RESULTS

In the study, 120 (75.0%) participants correctly recognized that individuals with HIV may appear healthy, while 123 (76.9%) participants admitted that HIV carriers have lower resistance to other diseases. Additionally, 126 (78.8%) participants confirmed an association between the virus and oral lesions, and 137 (85.6%) participants were aware of HIV transmission through blood. Moreover, 150 (93.7%) participants expressed their willingness to support, treat, and assist patients with AIDS, while only 10 (6.3%) participants expressed unwillingness. Notably, no statistically significant differences were found between dental assistants and hygienists in their knowledge and attitudes toward HIV/AIDS and people with AIDS.

CONCLUSION

This study demonstrated that dental hygienists and assistants possess good general knowledge regarding HIV/AIDS and are well-informed about the disease's transmission routes. Moreover, a significant majority endorses the importance of treating and supporting AIDS patients.

Salivary biochemical parameters in people living with HIV on ART and dental caries: a cross-sectional study in Monastir, Tunisia

BACKGROUND

Studies regarding salivary biochemical parameters and dental caries in adult people living with HIV/AIDS (PLWHA) are scanty.

AIM

To investigate salivary biochemical parameters and dental caries in adult PLWHA who are on antiretroviral therapy (ART) and compare the findings with people negative for HIV infection.

METHODS

The study included 50 HIV positive individuals as a test group (TG) and 50 HIV negative individuals as a control group (CG). Dental examination was performed according to WHO guidelines to assess DMFT. Digital panoramic radiographs were taken to detect additional infectious foci. Non-stimulated saliva was collected between 9 and 12 a. m for 5 min to evaluate 18 biochemical parameters and salivary flow rate (SFR). Parametric and non parametric tests were used according to data distribution. The level of significance was set at p < 0.05%.

RESULTS

Patients' mean ages and M/F sex ratios for TG and CG were 38.80 ± 9.69 y/o. vs. 37.98 ± 13.47 y/o. and 3.54 vs. 2.33, respectively. Higher means of decayed teeth were recorded in TG, 4.47 ± 3.00 vs. 3.88 ± 2.81 in CG with no significant difference (p = 0.41). Means of filled teeth were significantly lower in TG 2.38 ± 2.16 vs. 4.16 ± 3.35 in CG (p = 0.01), respectively. No statistical significant difference was noted in DMFT indices between the 2 groups (8.04 ± 6.90 vs. 8.52 ± 6.24, p = 0.71). The following salivary parameters were significantly lower in TG compared to CG, respectively: mean SFR 0.44 ± 0.18 ml/min vs. 0.61 ± 0.26 ml/min; median levels of sodium and chlorides, 4 mmol/L and 13.5 mmol/L vs. 9 mmol/L and 19 mmol/L (p < 0.001) and uric acid, 103.50 mmol/L vs. 163 (p = 0.009). However, higher median levels were recorded with calcium, 1.09 mmol/L vs. 0.54 (p < 0.001) and sIgA 23 mg/dl vs. 5 mg/dl (p < 0.001). In TG, a positive correlation was found between DC, potassium, urea, and chlorides (p < 0.05). Salivary renal and hepatic biomarkers were comparable between the two groups.

CONCLUSIONS

PLWHA have shown an alteration in some salivary parameters, more decayed teeth and less filled teeth. Preventive measures should be implemented to lower dental caries and enhance accessibility to oral care services. In addition, saliva can be utilized to monitor oral and general health status among PLWHA on ART.

Immune indices and oral health in patients infected with the human immunodeficiency virus

BACKGROUND

The human immunodeficiency virus (HIV) is the causative agent of acquired immunodeficiency syndrome (AIDS). During the incubation period of AIDS, oral manifestations may precede systemic symptoms; therefore, it is vitally important to explore the relationship between HIV and oral health and other indicators. This study aimed to further assess the correlation between demographic risk factors, the dental health of HIV-infected patients, and the correlation of oral health indicators with CD4+ T-cell counts (CTCCs) and HIV viral loads (HIV-VLs).

METHODS

Demographic data on 108 HIV-infected patients were first recorded by questionnaire from March 2016 to November 2018. Patients' dental health and oral lesions were assessed by a dental specialist; in addition, they were tested for CTCCs and HIV-VLs by flow cytometry and NucliSENS EasyQ® HIV-1 virometer. Finally, the links between CTCC, HIV-VL, and the dental health (including oral lesions) of the patients were analyzed.

RESULTS

We found that age, marital status, and body mass index (BMI) were relevant to the patient's dental health (P < 0.05) and that their oral hygiene was relevant to their dental health (P < 0.05). However, HIV-VL was not directly related to periodontal/dental clinical indicators (P > 0.05). We discovered that the oral lesions in HIV-infected patients were related to decreased CTCCs and increased HIV-VLs (P < 0.05).

CONCLUSIONS

We concluded that HIV-infected patients with severely impaired immune function tend to have poor dental health. Moreover, the prevalence of oral lesions was negatively correlated with CTCC and positively correlated with HIV-VL.

Clinical Assessment and Management in Improving the Quality of Life of HIV/AIDS Patients with Oral Candidiasis: A Case Series

Introduction

Oral candidiasis is the most prevalent opportunistic infection in patients with human immunodeficiency virus (HIV) or acquired immunodeficiency syndrome (AIDS), impacting their quality of life. This report aims to emphasize the importance of clinical assessment and management of HIV/AIDS patients with oral candidiasis to improve their quality of life.

Case

Five male patients, aged between 32 and 71 years, came to the HIV clinic and complained of white plaques in their mouths and painful swallowing. The World Health Organization's (WHO) clinical staging of all patients was 4. Three patients had not yet received antiretroviral therapy (ART), and their total lymphocyte counts (TLC) of <1.170 cells/mm3. Two patients had dropped out of ART with CD4 counts were <40 cells/mm3. The body mass index of two patients was underweight, while the others were normal. The oral hygiene index simplified (OHI-S) of the patients was fair to poor. The quality of life assessment using the oral health impact profile 14 (OHIP-14) questionnaires before therapy showed values from 6-20. Clinical examination defined the diagnosis as oral candidiasis, exfoliative cheilitis, oral hairy leukoplakia, and a cytomegalovirus-related ulcer.

Case Management

The patients were treated with fluconazole, 0.2% chlorhexidine gluconate mouthwash, 2% miconazole cream, diphenhydramine, and multivitamins. The oral lesions were improved within 14 days to a month of treatment, and OHIP-14 scores were significantly reduced (0-3).

Conclusion

Clinical assessment is important in managing HIV/AIDS patients with oral candidiasis, which improves the patient's quality of life. Therefore, routine clinical assessment and management of HIV/AIDS patients are strongly recommended.

Influence of HIV infection on cognition and overall intelligence in HIV-infected individuals: advances and perspectives

It is now well understood that HIV-positive individuals, even those under effective ART, tend to develop a spectrum of cognitive, motor, and/or mood conditions which are contemporarily referred to as HIV-associated neurocognitive disorder (HAND), and which is directly related to HIV-1 infection and HIV-1 replication in the central nervous system (CNS). As HAND is known to induce difficulties associated with attention, concentration, and memory, it is thus legitimate and pertinent to speculate upon the possibility that HIV infection may well influence human cognition and intelligence. We therefore propose herein to review the concept of intelligence, the concept of cells of intelligence, the influence of HIV on these particular cells, and the evidence pointing to differences in observed intelligence quotient (IQ) scores between HIV-positive and HIV-negative individuals. Additionally, cumulative research evidence continues to draw attention to the influence of the gut on human intelligence. Up to now, although it is known that HIV infection profoundly alters both the composition and diversity of the gut microbiota and the structural integrity of the gut, the influence of the gut on intelligence in the context of HIV infection remains poorly described. As such, we also provide herein a review of the different ways in which HIV may influence human intelligence via the gut-brain axis. Finally, we provide a discourse on perspectives related to HIV and human intelligence which may assist in generating more robust evidence with respect to this issue in future studies. Our aim is to provide insightful knowledge for the identification of novel areas of investigation, in order to reveal and explain some of the enigmas related to HIV infection.

Oral health outcomes in an HIV cohort with comorbidities- implementation roadmap for a longitudinal prospective observational study

BACKGROUND

Long-term antiretroviral therapy (ART) perpetually suppresses HIV load and has dramatically altered the prognosis of HIV infection, such that HIV is now regarded as a chronic disease. Side effects of ART in Patients With HIV (PWH), has introduced new challenges including "metabolic" (systemic) and oral complications. Furthermore, inflammation persists despite great viral load suppression and normal levels of CD4+ cell count. The impact of ART on the spectrum of oral diseases among PWH is often overlooked relative to other systemic complications. There is paucity of data on oral complications associated with ART use in PWH. This is in part due to limited prospective longitudinal studies designed to better understand the range of oral abnormalities observed in PWH on ART.

METHODS

We describe here the study design, including processes associated with subject recruitment and retention, study visit planning, oral health assessments, bio-specimen collection and preprocessing procedures, and data management and statistical plan.

DISCUSSION

We present a procedural roadmap that could be modelled to assess the extent and progression of oral diseases associated with ART in PWH. We also highlight the rigors and challenges associated with our ongoing participant recruitment and retention. A rigorous prospective longitudinal study requires proper planning and execution. A great benefit is that large data sets are collected and biospecimen repository can be used to answer more questions in future studies including genetic, microbiome and metabolome-based studies.

Identification of the causal relationship between sleep quality, insomnia, and oral ulcers

BACKGROUND

Multiple epidemiological studies have posited a potential association between sleep quality and the risk of oral diseases, yet the resulting conclusions have remained contentious, and the presence of a causal link remains equivocal. In this study, we aimed to investigate the causal relationship between sleep duration, insomnia, and common oral diseases.

METHODS

We utilized genetic correlation and two-sample Mendelian randomization analyses based on summary statistics from genome-wide association studies of sleep duration (N = 460,099), insomnia (N = 462,341), mouth ulcer (N = 385,026), oral cavity cancer (N = 4,151), and periodontal disease (N = 527,652).

RESULTS

Our results revealed a negative genetic correlation between sleep duration and mouth ulcer (genetic correlation: -0.09, P = 0.007), while a positive genetic correlation between insomnia and mouth ulcer was observed (genetic correlation: 0.18, P = 2.51E-06). Furthermore, we demonstrated that longer sleep duration is significantly associated with a reduced risk of mouth ulcers (OR: 0.67, 95% CI: 0.54-0.83, P = 2.84E-04), whereas insomnia is nominally associated with an increased risk of mouth ulcers (OR: 1.40, 95% CI: 1.01-1.95, P = 0.044). In contrast, no significant association was detected between sleep quality and periodontal disease or oral cavity cancer.

CONCLUSIONS

This work provides robust evidence to support the notion that enhanced sleep quality may confer a decreased risk of oral ulcers, thereby bearing considerable clinical relevance.

Therapeutic Potential of Cannabis: A Comprehensive Review of Current and Future Applications

Historically, cannabis has been valued for its pain-relieving, anti-inflammatory, and calming properties. Ancient civilizations like the Egyptians, Greeks, and Chinese medicines recognized their therapeutic potential. The discovery of the endocannabinoid system, which interacts with cannabis phytoconstituents, has scientifically explained how cannabis affects the human immune system, including the central nervous system (CNS). This review explores the evolving world of cannabis-based treatments, spotlighting its diverse applications. By researching current research and clinical studies, we probe into how cannabinoids like Δ9-tetrahydrocannabinol (THC) and cannabidiol (CBD) help to manage conditions ranging from chronic pain, persistent inflammation, cancer, inflammatory bowel disease, and neurological disorders to even viral diseases such as Human Immunodeficiency virus (HIV), SARS-CoV-2. and the emerging monkeypox. The long-term recreational use of cannabis can develop into cannabis use disorder (CUD), and therefore, understanding the factors contributing to the development and maintenance of cannabis addiction, including genetic predisposition, neurobiological mechanisms, and environmental influences, will be timely. Shedding light on the adverse impacts of CUD underscores the importance of early intervention, effective treatment approaches, and public health initiatives to address this complex issue in an evolving landscape of cannabis policies and perceptions.

Molecular Pathogenesis of Human Immunodeficiency Virus-Associated Disease of Oropharyngeal Mucosal Epithelium

The oropharyngeal mucosal epithelia have a polarized organization, which is critical for maintaining a highly efficient barrier as well as innate immune functions. In human immunodeficiency virus (HIV)/acquired immune deficiency syndrome (AIDS) disease, the barrier and innate immune functions of the oral mucosa are impaired via a number of mechanisms. The goal of this review was to discuss the molecular mechanisms of HIV/AIDS-associated changes in the oropharyngeal mucosa and their role in promoting HIV transmission and disease pathogenesis, notably the development of opportunistic infections, including human cytomegalovirus, herpes simplex virus, and Epstein-Barr virus. In addition, the significance of adult and newborn/infant oral mucosa in HIV resistance and transmission was analyzed. HIV/AIDS-associated changes in the oropharyngeal mucosal epithelium and their role in promoting human papillomavirus-positive and negative neoplastic malignancy are also discussed.

A Review of Basic Knowledge of HIV Infection for Orthodontic Management of HIV Patients

Human immunodeficiency virus (HIV) is a retrovirus that causes an infection affecting immunity-providing white blood cells. The HIV pandemic is far from over and is a major socio-economical burden. As there is no cure yet, prevention of new infections is the major path to control the infection. There is a low chance of orthodontic procedures carrying a risk of HIV infection transmission. It is important to have knowledge about the disease to effectively and safely treat known or unknown patients with HIV.

Ulceration and a White Lesion of the Tongue in a Male HIV Positive Patient: A Journey on the Avenue of Differential Diagnoses in Search of a Solution

Oral lesions are early indicator of immunosuppression, leading to HIV new diagnoses. The type of oral lesions can reveal opportunistic diseases that are correlated with the severity of immune depletion. Highly active antiretroviral therapy decreases the incidence of opportunistic oral infections, whereas a large variety of lesions are frequently experienced in people with HIV. Overlapping pathogenic mechanisms and multiple contributing etiologies are related to unusual, atypical oral lesions that are challenging in the clinical practice. We present a rare case of eosinophilic granuloma of the tongue in an older male HIV patient with severe immunosuppression due to the failure of antiretroviral treatment. Differential diagnoses considered squamous carcinoma, lymphoma, viral, fungal or bacterial infections and autoimmune disorders, as well as the influence of HIV immune disfunctions or the influence of cannabidiol use. The histopathologic and immunohistochemistry examination clarified the inflammatory reactive benign substrate of the lesion, although future survey of the oral lesions is essential.

Case Series of HIV-Associated Oral Lesions Among Antiretroviral-Naive Patients During the COVID-19 Pandemic

Introduction

The coronavirus disease 2019 (COVID-19) pandemic has a serious impact on HIV-infected individuals due to limited access to treatment services. This report aimed to describe four cases of oral lesions in HIV-infected antiretroviral-naive patients found during the COVID-19 pandemic.

Case

Four patients, males, with an age ranged from 29 to 53 years, came to Oral Medicine Department with chief complaints of lesions on their mouth. They had postponed their visit to healthcare services due to limited access during pandemic. Three patients had just been diagnosed with HIV and had not yet received anti-retrovirus, while 1 patient had not yet been detected with HIV. From the clinical examination and laboratory findings, we diagnosed the lesions with mucous patches, chronic atrophic candidiasis, angular cheilitis, necrotizing ulcerative gingivitis, linear gingival erythema, cytomegalovirus-associated ulcers, and oral hairy leukoplakia.

Case Management

We gave chlorhexidine gluconate 0.2% mouthwash for mucous patches, nystatin oral suspension for chronic atrophic candidiasis, miconazole cream 2% for angular cheilitis, debridement with hydrogen peroxide 1.5% and rinsed with normal saline for necrotizing ulcerative gingivitis, and diphenhydramine hydrochloride and 0.2% chlorhexidine gluconate for CMV ulcers. All patients showed good clinical improvement after the treatments.

Conclusion

Oral lesions are still commonly found in HIV-infected patients during COVID-19 pandemic. Dentists remain to have a crucial role in the early diagnosis and treatment of HIV-associated oral lesions during COVID-19 pandemic that will have an impact on HIV treatments, also in implementing the Bali Declaration on oral health in HIV/AIDS 2019 to support UNAIDS goal to end AIDS by 2030.

Factors Associated with Periodontitis in Patients with and without HIV

Purpose

The aim of this study was to compare clinical periodontal conditions in HIV-positive people on HAART with an HIV-negative group, in addition to investigating factors associated with periodontitis in the entire sample.

Methods

This was a cross-sectional study. Data were collected by oral clinical examination for the diagnosis of periodontitis, review of medical records, and application of a questionnaire containing personal data, deleterious habits, and oral hygiene habits for the other variables. The results were analyzed by Pearson's χ ² test and Student's t-test. A logistic regression model was constructed for the multivariate analysis and periodontitis was defined as a dependent variable. The analysis was performed on the entire sample (HIV+ and HIV-) and also on the group consisting of only people living with HIV.

Results

Individuals older than 43 years old and with HIV were more likely to develop moderate and severe periodontitis (47.80 and 4.84 times, respectively). When analyzing only HIV+, in addition to age (OR = 2.795; CI = 1.080-7.233), the use of nonnucleoside reverse transcriptase inhibitors (NNRTIs) (OR = 2.841; CI = 1.135-7.112) was also associated with moderate and severe periodontitis.

Conclusion

It was possible to observe a higher prevalence of periodontitis among individuals with HIV, showing an association between the virus, advanced age, and moderate or severe periodontitis.
