The global changing pattern of the oral manifestations of HIV

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.     

AIDS update. Oral manifestations and management

The acquired immunodeficiency syndrome (AIDS) pandemic continues to increase in magnitude and to plague the world. Dental professionals knowingly or unknowingly are involved in this pandemic because of the need to provide dental care without discrimination. Additionally, oral manifestations of human immunodeficiency virus (HIV) infection are common and often are major patient complaints as well as sometimes the first sign or symptom of HIV infection. Oral manifestations of HIV immunosuppression include opportunistic infections, autoimmune diseases, and malignancies. Therefore, the dental clinician has the opportunity to recognize and diagnose oral manifestations of HIV infection and to participate in patient management and counseling.     

Oral care of HIV infected patients: the knowledge and attitudes of Irish dentists.

As the numbers of people with HIV infection and AIDS increase, so will the contribution required from dental practitioners. A postal questionnaire survey was therefore conducted among dental practitioners in Ireland to determine their knowledge and attitudes towards HIV infection and the issues it raises for them. Although a majority of dentists were aware of the facts related to AIDS and the spread and oral manifestations of HIV infection, there were considerable gaps in their knowledge with regard to dental management. Only 41% were prepared to be engaged in continued care of HIV infected patients while contradicting opinions were expressed on the risk of HIV transmission in dentistry and attitudes towards HIV seropositive patients and staff. Further educational efforts on HIV infection and its implications in dentistry should be directed towards dentists in Ireland.     

Oral manifestations of HIV infection in 600 South African patients

Arendorf TM, Bredekamp B, Cloete CAC, Sauer G: Oral manifestations of HIV infection in 600 South African patients. J Oral Pathol Med 1998; 27: 176-9. C Munksgaard, 1998. Oral lesions associated with HIV infection, as classified by the EC-Clearinghouse on Oral Problems related to HIV infection and the WHO Collaborating Centre on Oral manifestations of the immunodeficiency virus, were studied in 600 consecutive HIV-infected patients in Cape Town, South Africa. One or more lesions were seen in 60.4% of cases. Combined candidal lesions were evident in 37.8%, hairy leukoplakia in 19.7% and combined gingival/periodontal lesions in 8.5% of patients seen. Lesions less commonly recorded include oral ulceration (2.9%) and Kaposi's sarcoma (1.5%). The clinical range of lesions seen is similar to those reported elsewhere, but socio-cultural differences allowed no reliable comparison. More than a quarter of our patients had oral soft tissue discomfort necessitating treatment; in 3.3% these were the presenting symptom. This indicates a potential major public health concern requiring education in recognition and appropriate referral and management.     

Oral manifestations among people living with HIV/AIDS in Tanzania

Background : This study aimed to determine the prevalence of various oral and peri‐oral manifestations in people living with HIV/AIDS in Tanzania. Methods : A cross sectional study. A total of 187 persons with HIV infection were recruited from non‐governmental organisations serving people living with HIV/AIDS, 16.6% were males and females 83.4%. Information on weight and height, as well as extra oral and intra oral examinations for different manifestations were gathered. Treatment and referral for special care were offered. Results : At least one oral lesion was present in 45% of the participants. Candidiasis (28.9%) and non‐tender lymphadenopathy (11.8%) were the most common lesions. Candidiasis occurred most frequently on lips/mucosa, and the tongue, and pseudomembranous candidiasis was the most frequent type. Candidiasis occurred with several other conditions and was statistically significantly associated with low body mass index (BMI). Conclusion : This community survey carried out in an African sub‐Saharan country showed that oral lesions are frequent among people living with HIV/AIDS. As emphasised by the World Health Organization Global Oral Health Programme, national HIV/AIDS programmes should incorporate oral health components.     

Dental lesions: Diagnosis and treatment

Oral health care has been an integral part of the care of patients with HIV infection and AIDS since the disease was first identified in the early eighties. The spectrum of HIV-associated opportunistic diseases occurring in the oral cavity propelled dental health care providers to the forefront of patient care. Infection control issues soon became important in oral health care for patients infected with HIV, and for the first decade these two issues overshadowed the concerns about appropriate management of the dental needs of HIV-infected patients. Several concerns need to be considered in the management of dental care for patients infected with HIV. These include decreased salivary flow and increased sugar intake, prevention and management of routine inflammatory gingival and periodontal disease as well as the atypical forms of gingival and periodontal disease associated with HIV infection (linear gingival erythema [LGE], necrotizing ulcerative gingivitis [NUG] and necrotizing ulcerative periodontitis [NUP]). Finally, although reports of complications secondary to dental treatment of HIV-infected individuals are rare, it is important to consider those factors related to the medical status of HIV-infected patients which may interfere with oral health care These include potential bleeding problems related to thrombocytopenia and disease or medication related liver abnormalities, increased risk of local infection particularly in patients with severe neutropenia and adverse effects of multiple medications taken by HIV patients. Prevention and management of dental and periodontal disease in HIV-infected individuals is important to self esteem, quality of life and maintenance of adequate nutritional intake. Oral health care continues to be an important component of overall health care for HIV-infected patients.     

Fungal infections associated with HIV infection

Oral candidiasis is perhaps the commonest infection seen in HIV disease. The aim of this workshop was to provide a sketch of the multifarious aspects of the disease from a global perspective. To this end the panellists addressed issues such as the virulence of Candida , emergence of antifungal resistance, management of candidiasis and other exotic, oral mycotic diseases. An all-pervasive theme was the dramatic differences in the management of fungal infections consequential to the availability (or the lack) of anti-HIV drugs in the developed and the developing world. Further, the social stigmata associated with the HIV disease in many developing regions in Africa and Asia appears to modify the therapeutic strategies. Additionally, the lesser-known regional variations in the disease manifestations and therapeutic approaches were stark. Further work is direly needed to address these issues.     

Oral research and dental treatment in HIV infection.

In June 1991, practicing, research, and academic dentists attended a symposium on oral research and dental treatment in HIV infection at Guy's Hospital in London, England. Oral lesions in HIV infection were classified as strongly associated, probably associated, and possibly associated with HIV infection. A speaker stressed that those strongly associated with HIV infection should be of the most interest to general dental practitioners. Another speaker said that chronic erythematous candidiasis has emerged as an oral infection strongly associated with HIV infection in addition to pseudomembranous candidiasis. A dentist mentioned hairy leukoplakia as a new condition strongly associated with HIV infection. Other HIV associated periodontal disease included gingivitis, necrotizing gingivitis, and periodontitis. A speaker noted that AZT increases longevity of AIDS patients and the drugs dideoxyinosine and dideooxycytidine are being tested. Another dentist spoke about the issue of HIV infected dentists citing the example of the dentist in Florida who infected 5 patients. Other speakers addressed the cases and needs of asymptomatic HIV infected people. A survey of dentists showed that only 33% of dentists would provide dental care to HIV infected people and only 20% would if the patients had AIDS. A dentist addressed the problem of a lack of data on prevention and treatment of oral lesions since their etiology and pathogenesis were unknown. Other presentations focused on research on antibodies and DNA probes in reference to saliva and subgingival flora. The symposium revealed the ran ge and depth of research going on in British schools on oral manifestations of HIV infection.     

Oral manifestations of HIV infection in infants: a review article

The vast majority of children with HIV infection present oral manifestations among the first signs of illness. These lesions are not produced directly by the virus, but are manifestations associated with HIV infection, and are not pathognomic of the infection itself. Some of these oral lesions have a prognostic value with regard to progression of the infection and the appearance of AIDS; independently of other, more commonly used markers. The essential risk factors that influence the development of such oral manifestations are the low number of CD4+ lymphocytes, xerostomia, and the lack of anti-retroviral therapy. Opportunist infections, such as mycoses -- including pseudomembranous oral candidiasis, are found with higher frequency; followed by the herpetic viral infections. The oral lesions that appear in infected children differ in prevalence from those found in seropositive adults, some, such as parotid hypertrophy, present more exclusively in children, others, such as periodontal bacterial infections and Kaposi's Sarcoma, are lesions that predominate in the adult HIV-infected population. Given the current impact of the pandemic caused by HIV, it is the responsibility of dental professionals to prevent, detect, treat and control the oral lesions in those patients infected with HIV. All of which will be reflected in a reduction in transmission, lower mortality and greater long-term survival for infected children.     

Oro-facial manifestations of HIV infections

Oral manifestations in HIV infected individuals are common and may occur as mycotic, bacterial or viral infections neoplasms or manifestations of unknown etiology. Some of the oral manifestations may be of importance in early diagnosis of HIV infection. In particular, oral candidiasis occurring as pseudomembranous, erythematous and hyperplastic types should be considered. Oral hairy leukoplakia, pathognomonic for an HIV infection, has been considered to represent a probable diagnostic marker for the development of AIDS. HIV gingivitis and periodontitis are of particular significance. Early and correct diagnosis of HIV-associated manifestations are of importance to the patient as well as to the dentist who should take adequate protection measures.     

HIV-associated periodontitis complicated by necrotizing stomatitis

This report describes a case of HIV-associated periodontitis complicated by necrotizing stomatitis in a homosexual male patient with AIDS. Necrotizing stomatitis is a rapidly progressive ulcerative and necrotic infection that causes massive destruction of the oral tissues and underlying bone. Like HIV periodontitis, it appears to be related to the immune suppression caused by human immunodeficiency virus (HIV) infection; importantly, it may be life threatening. In this case, initial resolution resulted from local debridement in association with metronidazole therapy. Long-term clinical management consisted of monthly professional prophylaxis, good oral hygiene, and daily rinses with chlorhexidine. This case suggests that progressive oral necrotizing infection should be recognized as one element in the spectrum of oral manifestations of HIV infection.     

Oral fungal and bacterial infections in HIV-infected individuals: an overview in Africa

Oral opportunistic infections developing secondary to human immunodeficiency virus (HIV) infection have been reported from the early days of the epidemic and have been classified by both the EC-Clearinghouse and the World Health Organisation (WHO). Among the fungal infections, oral candidiasis, presenting in African HIV-infected patients has been sporadically documented. We review the literature with respect to candidal carriage, oral candidiasis prevalence and the predictive value of oral candidiasis for a diagnosis of underlying HIV disease in African HIV-infected patients. The use of oral candidiasis as a marker of disease progression, the species of yeasts isolated from the oral cavity in Africa and the resistance of the yeasts to antifungal agents and treatment regimens are discussed. Orofacial lesions as manifestations of the systemic mycoses are rarely seen in isolation and few cases are reported in the literature from Africa. In spite of the high incidence of noma, tuberculosis, chronic osteomyelitis and syphilis in Africa, surprisingly there have been very few reported cases of the oral manifestations of these diseases in HIV-positive individuals. Orofacial disease in HIV-infected patients is associated with marked morbidity, which is compounded by malnutrition. The authors indicate specific research areas, initially directed at the most effective management strategies, which would complete data in this important area.     

Avoiding malpractice for nondental conditions. The example of human immunodeficiency virus

BACKGROUND: Dentists are legally liable for failing to recognize medical conditions that they identify while providing dental care and for failing to refer patients for follow-up care and testing. This article suggests ways to avoid liability using human immunodeficiency virus, or HIV, infection as an example. TYPES OF LITERATURE REVIEWED: The authors conducted a review of the legal literature to determine circumstances that would cause dentists to have legal liability for failing to recognize a medical problem. The authors also conducted a review of the dental literature to identify the most common signs of HIV infection that dentists might see in practice. RESULTS: The legal literature indicates that dentists can be held liable for failing to recognize medical problems, including HIV and acquired immunodeficiency syndrome. The dental literature shows that there are multiple signs and symptoms that indicate the potential for HIV infection to be the underlying cause of many oral diseases. PRACTICE IMPLICATIONS: Dentists should be familiar with the most common oral manifestations of medical conditions that are likely to be identified in the dental office, including those associated with HIV infection. They must recognize medical conditions and arrange for appropriate referral to avoid liability.     

Oral manifestations and dental status in paediatric HIV infection

Objective . To describe the incidence and prevalence of oral manifestations of HIV infection in a population of perinatally infected children.
Design . Retrospective and prospective study of a cohort of perinatally HIV-infected children.
Setting. Community hospital and community-based paediatric clinic.
Sample and methods . Forty perinatally HIV-infected children with a median age of 12 months were eligible and selected for the study, which included a medical chart review from birth and prospective follow-up. Each child was examined quarterly for oral manifestations, tooth eruption, and for 27 children, caries and periodontal status.
Results . The incidence of pseudomembranous candidiasis was 43% (95% CI, 27–58%) within 6 months of birth. Oral candidiasis (defined as pseudomembranous or erythematous) was positively associated with low CD4 counts and the occurrence of plaque. Children with low CD4 counts were also found to have fewer teeth than children with high CD4 counts, after adjusting for age.
Conclusions . Oral manifestations are common in paediatric HIV infection and are possible predictors of HIV disease progression. Primary care of HIV-infected children should include periodic oral examinations to monitor their HIV disease progression and to alleviate symptoms associated with oral opportunistic infections.     

Oral health in Australian HIV patients since the advent of combination antiretroviral therapy

Background: The introduction of combination antiretroviral therapy (cART) for the treatment of human immunodeficiency virus (HIV) has resulted in changes to the oral health of infected individuals. Little data are available describing prevalence and severity of oral manifestations in a post cART cohort of HIV positive patients. Methods: A retrospective case note analysis was performed at the Special Needs Unit (SNU), Adelaide Dental Hospital with emphasis on identifying the prevalence of HIV related oral manifestations (OM). A total of 498 (474 males: 24 females) HIV positive individuals were identified who had attended SNU for dental care between 2001 and 2008. Results: There were significant differences observed in the prevalence of oral manifestations between cART and non‐cART groups, and also in comparison to a previous pilot study. Individuals taking cART therapy tended to present with more evidence of linear gingival erythema, angular cheilitis, human papilloma virus associated squamous papillomas and xerostomia. Conclusions: The widespread adoption of cART in the treatment of HIV has altered the oral health profile of these individuals. These findings provide information on the incidence of oral conditions and demonstrate the need to identify and address oral health needs for people living with HIV.     

The third decade of HIV/AIDS: a brief epidemiologic update for dentistry

Dental professionals currently entering the dental workforce are witness to a significantly different set of oral health issues with HIV than those encountered when the epidemic began. Populations at risk for infection have changed over time and, in Canada, the United States, and the rest of the world, higher proportions of minorities and women have become infected. Medication regimens that help manage HIV as a more chronic disease have affected its presentation, its frequency and, perhaps, the significance of its oral manifestations. These medications may provoke comorbidities that challenge medical and dental disease management and health promotion. The dental office may become a site for rapid testing for HIV. The complexity of HIV infection and treatment behooves all health care professionals to be aware of developments in the prevention and epidemiology of HIV infection, and in oral health care for patients who are HIV-positive.     

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.     

PL10Oral manifestations of orogenital bacterial infections

Orogenital sex in the last decades has become a common sexual practice (fellatio and cunnilingus) between both heterosexual and homosexual individuals. Consequently, several sexually transmitted diseases (STDs) including bacterial infections, are a persistent problem in Europe and throughout the world, despite vigorous efforts in prevention and people education. The last two decades, HIV infection, revived the interest of the medical community and the people for the sexually transmitted diseases. Many of these bacterial infections present predominantly with characteristic oral signs and symptoms. As a result, it is imperative for the oral physician (stomatologist) to keep abreast of the latest updates in the behavior and to be aware of the whole spectrum of clinical manifestations of these diseases. Orogenital bacterial infections may be divided into two major categories: (i) Common including syphilis and gonorrhoea and (ii) Rare, including chlamydia trachomatis infection and tropical sexually transmitted infections (chancroid, donovanosis, lymphogranuloma venereum). Syphilis is the leader of sexually transmitted diseases and has been of great interest in the past and today and has played a central role in medicine for several decades. The oral lesions of syphilis (primary secondary and tertiary stages) have a broad spectrum of manifestations, which mimic a lot of other oral lesions. The recent incidence data, the oral manifestations, the laboratory tests and treatment of both categories of these diseases will be discussed, as the increased practice of oral sex has become a more important potential route of transmission for oral and genital bacterial pathogens. Stomatologists and Dentists, frequently evaluate oral mucosal manifestations and thus play an important role in the diagnosis and treatment of many of highly infectious sexually transmitted infections.
