Oral lesions and conditions associated with human immunodeficiency virus infection in 300 south Indian patients

BACKGROUND: Human immunodeficiency virus infection/acquired immunodeficiency syndrome (HIV/AIDS) is a major health problem in India. The National AIDS Control Organisation (NACO) of India reports a seropositivity of 25.03 per thousand for the whole country, as of October 1999. In spite of this high prevalence there are very few reports of oral lesions and conditions in Indian HIV/AIDS patients, which are important in early diagnosis and management of these patients. OBJECTIVE AND SETTING: The present report describes the oral lesions in 300 HIV positive symptomatic patients presenting to us at RAGAS-YRG CARE, a non-governmental organisation in Chennai, South India, over a period of 9 months in 1998. METHOD: Lesions were diagnosed on clinical appearance using international criteria. RESULTS: Of the 300 patients 89% had acquired the infection through heterosexual contact. There were 205 males and 95 females, aged from 7 months to 72 years. Forty-seven percent of the patients were in the age group 21-30 years. CD4 counts were ascertained for 105 patients, 64 (62%) had CD4 counts < or = 200. A total of 217 (72%) of the 300 patients had some oral lesion when examined. Gingivitis (47%) and pseudomembranous candidiasis (33%) were the most common oral lesions. The other oral lesions seen were oral mucosal pigmentation (23%), erythematous candidiasis (14%), periodontitis (9%), angular cheilitis (8%), oral ulcers (3%), oral hairy leukoplakia (3%), hyperplastic candidiasis (1%), oral submucous fibrosis (2%) and one case of leukoplakia. CONCLUSIONS: Oral lesions occur commonly in HIV infection. A comprehensive oral examination may not only suggest HIV disease but may also be useful in monitoring the disease progression. This is a cost-effective procedure, which may be useful in screening large populations in developing countries like India.     

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.     

The prevalence of AIDS-associated oral lesions in a cohort of patients with hemophilia

Oral and perioral lesions have been widely reported in homosexual males and intravenous drug abusers who are seropositive for the human immunodeficiency virus (HIV) or have acquired immunodeficiency syndrome (AIDS). Several case reports have also noted some AIDS-associated lesions among persons with hemophilia, but the prevalence of these lesions in hemophilia populations is not known. This study investigated the prevalence of oral and perioral lesions in a cohort of patients receiving care at a hemophilia treatment center. In a sample of 32 patients with a factor VIII deficiency and 5 patients with a factor IX deficiency who underwent oral examinations, more than 80% were HIV seropositive. Cervical lymphadenopathy was present in more than half of the patients who were HIV seropositive but was absent in those who were HIV seronegative. Intraoral AIDS-associated lesions were present only in patients for whom a diagnosis of AIDS had been made, indicating that oral lesions among persons with hemophilia who are HIV seropositive may be less prevalent than among homosexual males or intravenous drug abusers who are HIV seropositive.     

Common oral opportunistic infections in Human Immunodeficiency Virus infection/Acquired Immunodeficiency Syndrome: Changing epidemiology; diagnostic criteria and methods; management protocols

There were 36.9 million in the world living with human immunodeficiency virus (HIV) infection/acquired immunodeficiency syndrome (AIDS) as of 2017, and new infections have seen a reduction by 18% since 2010. But this rate of decline is not sufficient for the goal of eradication of AIDS by 2030. Only 21.7  million people infected with HIV have accesses to antiretroviral therapy, with the rest at risk of the potential complications of HIV infection. It has been shown that oral lesions are diagnostic and prognostic of HIV infection, and many oral opportunistic infections continue to be a major problem, particularly in developing countries. It is therefore important that dental surgeons be aware and updated to recognize and manage the oral effects of HIV infection/AIDS. This chapter describes the classification, diagnosis, and management of oral lesions in these patients, based on our current understanding of the infection. This review also discusses the standardization of diagnosis of oral lesions in HIV infection/AIDS patients, immune reconstitution inflammatory syndrome case definition, and the research priorities formulated at the 7th World Workshop on Oral Health and Disease in AIDS.     

Oral presentation of histoplasmosis in an immunocompetent patient: a diagnostic challenge

Histoplasmosis is a rare systemic fungal infection, primarily affecting the pulmonary system. Oral lesions are usually a manifestation of the disseminated form of the disease and most frequently observed in severely immunocompromised patients, such as those with advanced human immunodeficiency virus infection and/or frank acquired immune deficiency syndrome. The clinical presentation of the oral lesions may be difficult to distinguish from oral squamous cell carcinoma. The histopathological features are usually characteristic, but occasionally the organisms are scanty and not readily identified, which can preclude obtaining the correct diagnosis and ensuring appropriate management. Histoplasmosis is an unusual and rare cause of chronic non‐healing ulceration in the oral cavity. A case of histoplasmosis involving the oral cavity in an immunocompetent patient is reported, which was not recognized, resulting in the inappropriate management of the condition.     

A case series of acquired immunodeficiency syndrome patients with initial neoplastic diagnoses of intraoral Kaposi's sarcoma

BACKGROUND: Oral Kaposi's sarcoma (KS) may represent the initial clinical manifestation of immunosuppression in human immunodeficiency virus disease. This article reviews the treatment provided to these patients and the outcome of the disease and provides the opportunity to assess the impact of improvements in the medical therapy of acquired immunodeficiency syndrome on disease outcome. METHODS: A tumor registry was examined to identify patients in whom oral KS was the first neoplastic diagnosis. RESULTS AND CONCLUSIONS: Thirty-seven cases of oral KS representing 1.9% of all cases of KS were identified as the first malignant diagnosis in patients with acquired immunodeficiency syndrome. Patients with oral KS have limited survival; the cause of death is either infection or malignancy. In our study, the palate was the most common site of primary involvement in the oral cavity. Recently diagnosed patients remained alive longer than those diagnosed earlier, and the patients with the most recently diagnosed cases were alive at the completion of the study, suggesting that medical management of human immunodeficiency virus has improved with new therapies.     

Oral manifestations of HIV/AIDS in clients attending TASO clinics in Uganda

The objective of the study is to establish the prevalence of oral manifestations and their influence on oral functions. A total of 514 subjects aged 18 to 58 years (mean 42 years) were randomly recruited from five The AIDS Support Organization (TASO) clinics in Uganda. They were clinically examined for oral lesions under field conditions by four trained dentists based on World Health Organization criteria. Women constituted 74.5% of the study population. Oral manifestations were recorded in 72% of the subjects, out of which 70% had candidiasis of pseudomembranous, erythematous, and angular cheilitis variants. Non-Hodgkin’s lymphoma, atypical ulcers, necrotizing periodontitis, and hairy leucoplakia were least frequently observed in the subjects. Of those who had oral lesions (n = 370), 68.4% had some form of discomfort in the mouth. Tooth brushing, chewing, and swallowing were frequently associated with discomfort. Reported forms of discomfort were dry mouth, increased salivation, and burning sensation especially on taking salty and spicy foods or acidic drinks. Only 8.5% (n = 44) of the subjects were taking medications specifically for oral lesions, which included antifungal, antiviral, and antibacterial agents. None of the subjects were on antiretroviral therapy. Oral lesions associated with human immunodeficiency virus/acquired immunodeficiency syndrome in TASO clients is a major public health problem requiring education in recognition and appropriate management.     

AIDS and the oral cavity. Epidemiology and clinical oral manifestations of human immune deficiency virus infection: a review

Since the first patients with acquired immune deficiency syndrome (AIDS) were seen in 1981, the disease has been recognized as an epidemic, now considered a major health threat. This article reviews, on the basis of the literature and personal observations of 120 human immune deficiency virus (HIV) infected patients, some aspects of the HIV (HTLV III/LAV) infection with emphasis on epidemiology and clinical aspects. The clinical oral manifestations include 5 groups of lesions: fungal infections, bacterial infections, viral infections, neoplasms and lesions of unknown etiology. In total, these 5 groups comprise 34 different lesions of the oral cavity.     

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.     

Frequency of oral manifestations in children infected with human immunodeficiency virus.

OBJECTIVE: The main objective of this study was to investigate the frequency of oral manifestations in children with acquired immunodeficiency syndrome. It also attempted to correlate the presence of lesions with the patient's degree of immunosuppression, as measured by the T4/T8 ratio. METHOD AND MATERIALS: Oral examinations were performed in 51 children with acquired immunodeficiency syndrome for a 2-year period. A questionnaire used in this investigation was based on the children's classification proposed by the Centers for Disease Control in 1987. The children's T4/T8 ratios were obtained from their medical files. RESULTS: Pseudomembranous candidiasis was the most common lesion, found in 21.57% of the children. Salivary gland disease was present in 19.61% of patients. Erythematous candidiasis was observed in 5.88%, and linear gingival erythema and oral hairy leukoplakia were both observed in 1.96% of children. Children with a T4/T8 ratio < 0.5 were more prone to development of pseudomembranous candidiasis. CONCLUSION: Pseudomembranous candidiasis was the most common type of oral lesion in human immunodeficiency virus-positive children with acquired immunodeficiency syndrome. There was a relationship between the frequency of oral manifestations and the patient's T4/T8 ratio.     

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.     

Changing dentists' knowledge, attitudes, and behaviors relating to AIDS: a controlled educational intervention

The efficacy of an educational intervention designed to improve dentists' knowledge, attitudes, and behaviors about acquired immune deficiency syndrome (AIDS) was tested. The intervention had three components: computerized feedback comparing participants' own knowledge, attitudes, and behaviors with those of fellow participants and with an ideal; periodic bulletins; and telephone conference calls with experts. The group receiving the educational package had better scores than a control group on outcomes of willingness to treat persons with AIDS; identification of human immunodeficiency virus lesions; knowledge of AIDS; and completeness of both intraoral and extraoral examinations. It was concluded that intervention is one approach to increasing dentists' positive response to the AIDS epidemic.     

Oral mucosal ulceration due to cytomegalovirus associated with human immunodeficiency virus infection. Case report and brief review

Reports of oral lesions associated with cytomegalovirus (CMV) infection in human immunodeficiency virus (HIV) infected patients are uncommon¹. In this article a case of CMV infection associated with oral mucosal ulceration and a brief review of the subject is presented. Establishing the cause of ulceration is important in determining a definitive diagnosis and prescribing appropriate therapy. It is important to recognize that CMV associated oral mucosal ulceration may be the initial manifestation of human immunodeficiency virus (HIV) infection.     

Oral malignancies in HIV disease: changes in disease presentation, increasing understanding of molecular pathogenesis, and current management

Infection with human immunodeficiency virus (HIV) and progression to acquired immune deficiency syndrome (AIDS) are associated with a vide variety of morbidities. Local and systemic diseases can develop in association with HIV infection and may manifest themselves as malignancies of the oropharynx. Advances in HIV management, fueled by increasing understanding of molecular pathogenesis, have resulted in marked changes in the prevalence of oral malignant disease. This paper discusses recent trends in the presentation and treatment of malignancies related to HIV and AIDS with an emphasis on malignancies seen in the oral cavity.     

The effect of antiretroviral therapy on the prevalence of oral manifestations in HIV-infected patients: A UK study

OBJECTIVE: The purpose of this study was to compare the prevalence of oral manifestations in human immunodeficiency virus (HIV)-infected patients on monotherapy, dual therapy, or triple therapy with the prevalence of those not on antiretroviral therapy (ART). STUDY DESIGN: A cross-sectional study of the oral manifestations of HIV was carried out on 284 HIV-infected patients, 89 of whom were undergoing ART (12 on monotherapy, 41 on dual therapy, and 36 on triple therapy) and 195 who were not undergoing ART. Oral manifestations were recorded by using established presumptive clinical criteria. Chi-square statistical tests and separate bivariate analyses were conducted by using the Spearman rank correlation to describe the relationship between the prevalence of oral lesions and ART. RESULTS: The detection of oral manifestations was significantly decreased in subjects on dual therapy and subjects on triple therapy in comparison with patients on monotherapy (P <.05) and those on no ART regimen (P =.014). Oral manifestations were also significantly increased, with CD4 counts <200 cells/mm(3) and a viral load >3000 copies/mL (P <.001). CONCLUSIONS: Compared with the non-ART group, subjects on combination ART had significantly fewer HIV-related oral manifestations-probably as a result of an expression of their reconstituted immune system.     

Detection of HIV in the dental pulp of a patient with AIDS

Dental pulp tissue from a patient with acquired immune deficiency syndrome (AIDS) was examined to determine the presence of the human immunodeficiency virus (HIV). The results found a high concentration of proviral HIV DNA.     

HIV and AIDS--the ethical dilemma central to many issues in HIV/AIDS revolves around individual good versus societal good.

Using patient advocacy as a point of departure, there are three possible ethical options where the human immunodeficiency virus/acquired immune deficiency syndrome (HIV/AIDS) is concerned: a 'strict advocacy' approach, a 'moderate advocacy' approach and a 'no advocacy' approach. In South Africa, a 'moderate advocacy' approach is favoured in general.     

Oral manifestations of recently described viral infections, including AIDS.

Oral viral diseases secondary to human immunodeficiency virus-1 infection are not commonly observed, except for Epstein-Barr virus infection. For the most part, members of the herpes virus group and the human papilloma viruses are involved. With the introduction of techniques like the polymerase chain reaction, the level of detection has been changed considerably. However, the application of these techniques may also result in difficulties of interpretation, such as is the case with the detection of human papilloma virus in human immunodeficiency virus-associated Kaposi's sarcoma, as recently described. The possible association of "new" viruses with well-known diseases such as Sj?gren's syndrome or Paget's disease are of great interest; but the etiologic role of these particles in the disease process has yet to be determined (Scully, in Millard and Mason, eds. Perspectives on 1988 World Workshop on Oral Medicine. YearBook Publishing, 1989, pp 179-182). Oral manifestations in the course of human immunodeficiency virus disease and acquired immunodeficiency syndrome are numerous and have long been considered important for clinical diagnostic reasons. The present review is focused on viral diseases with oral manifestations associated with human immunodeficiency virus infection as well as with some "new" viral diseases that may also produce orofacial symptoms.     

Effect of PI-HAART on the prevalence of oral lesions in HIV-1 infected patients. A Greek study

OBJECTIVE: To investigate the association between the prevalence of oral lesions and highly active antiretroviral therapy (HAART) including a protease inhibitor (PI). DESIGN: Prospective study. PATIENTS AND METHODS: Ninety-five consecutive patients, attending an AIDS Unit, in Greece entered the study. Fourty-four patients were receiving PI- HAART, 14 patients were on double antiretroviral therapy, and 37 patients were not receiving antiretroviral therapy at the time of oral examination. Oral lesions were diagnosed by established presumptive clinical criteria. MAIN OUTCOME MEASURES: Oral lesions were scored. CD4 counts and viral load were determined and related to the prevalence of oral lesions. RESULTS: Oral lesions, and specifically oral candidiasis, were significantly reduced (P < 0.001) in patients receiving PI-HAART. Oral lesions were significantly increased in patients with CD4 counts <200 cells microl(-1) and viral load >20,000 copies ml(-1) (P < 0.001). The percentage of patients, with lesions on PI-HAART, and with CD4 < 200 and viral load >20,000 was 1.5 times lower (37.5%vs 58.8%, P < 0.001) than that of patients not receiving antiretroviral therapy, but with similar immune and viremic status. CONCLUSIONS: Oral lesions were significantly reduced in patients on PI-HAART. A direct anticandidal effect of PI was suggestive and seemed to have accounted, beyond the HAART-related immune reconstitution, for the reduction of candidiasis and all other oral lesions.     

Oral lesions mimicking hairy leukoplakia: a diagnostic dilemma

Oral hairy leukoplakia is seen in immunosuppressed persons infected with the human immunodeficiency virus and is a predictor of the development of acquired immunodeficiency syndrome in that population. Over the past 3 years we have seen 16 examples of a lesion that histologically resembles hairy leukoplakia but is found in patients who are not in risk groups for acquired immunodeficiency syndrome. All these specimens tested negative for Epstein-Barr virus DNA and for human papillomavirus antigen. Sera from five of the 16 patients were tested for antibodies to human immunodeficiency virus, and all results were negative. These findings suggest that the diagnosis of hairy leukoplakia cannot be based on histologic criteria alone but should be verified by DNA in situ hybridization for Epstein-Barr virus.
