Abstract
Human immunodeficiency virus (HIV) supresses immune system, primarily cell-mediated immunity. Cluster of differentiation 4 (CD4) cell count, viral load, and oral lesions are the most important laboratory parameters to evaluate the evolution of acquired immunodeficiency syndrome. The present study aims to determine the incidence of HIV-related oral lesions with CD4 cell count and viral load in Yunnan, China.A cross-sectional study was conducted from December 2007 to December 2009, in 1812 HIV positive patients from Department of Infectious Diseases in Kunming Third People's Hospital. CD4, CD8, and viral load data were collected and analyzed statistically using SPSS 11.3.Out of 1812 HIV positive patients, 929 (51.27%) were associated with 1 or more oral lesions. The most common oral lesions observed were Candida Pseudomembranous (13.75%), Candida erythematous (10.93%), Oral hairy leukoplakia (7.95%), Aphthous ulcer (6.18%), Herpes simplex infection (5.58%). In most patients with oral lesions, the CD4 cell count was < 200/μL. The incidence of oral lesions was lower when CD4 count was > 200/μL and with undetectable (P < .01) HIV viral load. Almost no oral lesions was observed when CD4 count > 500/μL (P < .01). With highly active antiretroviral therapy, reduction in HIV-related oral lesions was observed especially in Candida erythematous, Candida Pseudomembranous, Oral hairy leukoplakia, and Aphthous ulcer.The higher incidence of oral lesions with lower CD4 count (<200/μL) in HIV-infected patients indicated importance of CD4 cell count in identifying disease progression.

Abstract
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.

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
Human Immunodeficiency Virus (HIV) transmission through genital and rectal mucosa has led to intensive study of mucosal immune responses to HIV and to the development of a vaccine administered locally. However, HIV transmission through the oral mucosa is a rare event. The oral mucosa represents a physical barrier and contains immunological elements to prevent the invasion of pathogenic organisms. This particular defense differs between micro-compartments represented by the salivary glands, oral mucosa, and palatine tonsils. Secretory immunity of the salivary glands, unique features of cellular structure in the oral mucosa and palatine tonsils, the high rate of oral blood flow, and innate factors in saliva may all contribute to the resistance to HIV/Simian Immunodeficiency Virus (SIV) oral mucosal infection. In the early stage of HIV infection, humoral and cellular immunity and innate immune functions in oral mucosa are maintained. However, these particular immune responses may all be impaired as a result of chronic HIV infection. A better understanding of oral mucosal immune mechanisms should lead to improved prevention of viral and bacterial infections, particularly in immunocompromised persons with Acquired Immune Deficiency Syndrome (AIDS), and to the development of a novel strategy for a mucosal AIDS vaccine, as well as vaccines to combat other oral diseases, such as dental caries and periodontal diseases.

Abstract
HIV infection is a major global health problem affecting developing and developed countries alike. Oral lesions that are associated with this disease are important, since they affect the quality of life of the patient and are useful markers of disease progression and immunosuppression. Oral lesions in HIV infection have been well-documented in developed countries, but there are fewer reports on oral lesions from developing countries. Oral candidiasis is the most common opportunistic infection seen in all continents. Kaposi’s sarcoma has been reported only from Africa and Latin America, while histoplasmosis and penicilliosis were reported in patients with advanced disease from Thailand. HIV-associated salivary gland disease has a high prevalence in Africa and Latin America, especially in the pediatric group. It is clear that there are considerable regional variations in the oral manifestations of HIV infection, depending both on the populations studied and on the clinical expertise available, among other factors. Well-designed and -documented studies are necessary for the correct assessment of the nature and magnitude of the problem in developing countries, if oral health measures are to be effectively formulated for the HIV-infected.

Abstract
Candida species present both as commensals and opportunistic pathogens of the oral cavity. For decades, it has enthralled the clinicians to investigate its pathogenicity and to improvise newer therapeutic regimens based on the updated molecular research. Candida is readily isolated from the oral cavity, but simple carriage does not predictably result in development of an infection. Whether it remains as a commensal, or transmutes into a pathogen, is usually determined by pre-existing or associated variations in the host immune system. The candida infections may range from non-life threatening superficial mucocutaneous disorders to invasive disseminated disease involving multiple organs. In fact, with the increase in number of AIDS cases, there is a resurgence of less common forms of oral candida infections. The treatment after confirmation of the diagnosis should include recognizing and eliminating the underlying causes such as ill-fitting oral appliances, history of medications (antibiotics, corticosteroids, etc.), immunological and endocrine disorders, nutritional deficiency states and prolonged hospitalization. Treatment with appropriate topical antifungal agents such as amphotericin, nystatin, or miconazole usually resolves the symptoms of superficial infection. Occasionally, administration of systemic antifungal agents may be necessary in immunocompromised patients, the selection of which should be based upon history of recent azole exposure, a history of intolerance to an antifungal agent, the dominant Candida species and current susceptibility data.

Abstract
Objectives The authors have conducted a systematic review of oral manifestations of HIV from studies conducted in Asia to establish the characteristics and prevalence of individual oral manifestations in Asia, and to assess the direction of future research studies on oral manifestations of HIV in Asia. Material and Methods The electronic retrieval systems and databases searched for relevant articles were PubMed [MEDLINE], EBSCO, and EMBASE. The search was for limited articles published in English or with an English abstract and articles published during the period January 1995 to August 2014. The authors reached a final overall sample of 39 studies that were conducted in Asia. Results The median population size among all studies was 312.7 patients. Oral candidiasis [OC] was the most common oral manifestation [37.7%] in studies conducted in Asia. The overall prevalence of oral hairy leukoplakia and melanotic hyperpigmentation was computed to be 10.1% and 22.8% respectively. Thailand and India are primarily countries with maximum research on oral manifestations. Conclusions The research on oral manifestations of HIV in Asia has to upgrade to more interventional and therapeutic studies rather than the contemporary cross- sectional epidemiological descriptive studies. The authors have given suggestions and future directions for the implementation of clinical research of oral manifestations in HIV patients. Key words:Oral manifestations, HIV/AIDS, Asia, Systematic review.

Abstract
Fungal infections in humans occur as a result of defects in the immune system. An increasing emergence in oral Candidal and non-Candidal fungal infections is evident in the past decade owing to the rise in the immunodeficient and immunocompromised population globally. Oral Candidal infection usually involves a compromised host and the compromise may be local or systemic. Local compromising factors include decreased salivation, poor oral hygiene, wearing dentures among others while systemic factors include diabetes mellitus, nutritional deficiency, HIV infection/AIDS and others. Oral candidiasis is generally a localized infection and rarely appears as a systemic fungal disease whereas oral non-Candidal fungal infections are usually signs of disseminated disease. Some of the non-Candidal fungi that were once considered exotic and geographically restricted are now seen worldwide, beyond their natural habitat, probably attributed to globalization and travels. Currently infections from these fungi are more prevalent than before and they may present either as primary oral lesions or as oral manifestations of systemic mycoses. This review discusses the various predisposing factors, clinical presentations, clinical differential diagnosis, diagnosis and management of oral candidiasis, as well as briefly highlights upon a few of the more exotic non-Candidal fungi that infect the oral mucosa.

Abstract
Objective: This study was designed to compare the microbiological features of angular cheilitis (AC) in human immunodeficiency virus (HIV) seropositive and HIV seronegative individuals, in a group of south Indians. Materials and Methods: Swabs from oral commissures of 46 patients were obtained and inoculated on to Sabouraud's dextrose agar (SDA) supplemented with chloramphenicol, blood agar (BA) and MacConkey's agar (MCA) plates and cultured. α-hemolytic Streptococci, Staphylococcus albus, Staphylococcus aureus, Candida species, Klebsiella species and Pseudomonas species were cultured. Candidal colonies were further speciated by the conventional biotyping technique. Results: In AC of HIV seropositive patients Candida albicans and Staphylococcus aureus were more prevalent than that in HIV seronegative patients. Incidentally in patients with CD4 cell count less than 200 there was an increase in the incidence of Candidal and Staphylococcus aureus colonization when compared to patients with CD4 cell count higher than 200. Conclusion: The present study suggests a definite difference in the microbial flora of AC in HIV seropositive patients than that of HIV seronegative population.

Abstract
The aim of this study was to assess the prevalence of oral lesions in infectious-contagious diseases patients being treated in the University Hospital of the Federal University of Pará, northern Brazil. One hundred seven patients with infectious diseases were clinically investigated for oral lesions at the University Hospital of Pará, northern Brazil. From total sample, most patients were men (65.7%) with a mean age of 45.4 years. About prevalence of systemic diseases, tuberculosis was the most frequent illness, followed by AIDS, hepatitis types B and C, leishmaniasis, and meningitis. Analyzing oral manifestations, periodontal diseases and candidiasis were the most prevalent diseases in both genders, followed by recurrent aphthous ulcers, saburral tongue, simplex herpes, and squamous cell carcinoma. Of all 107 patients, only 10 males and 6 females did not present any oral manifestation. There was no statistical difference between genders with any systemic condition (P>0.05). The great prevalence of oral manifestations in hospitalized patients with systemic disorder emphasizes the need of integral dental care in this context, aiming at a multidisciplinary approach of patients. Therefore, presence of some oral conditions, such as candidiasis, should be an alert to different systemic conditions, once in assistance with physicians; dentists can influence the early diagnosis and treatment.

Abstract
Since the early 1990's, the death rate from AIDS among adults has declined in most developed countries, largely because of newer antiretroviral therapies and improved access to these therapies. In addition, from 2006 to 2011, the total number of new cases of HIV infection worldwide has declined somewhat and has remained relatively constant. Nevertheless, because of the large numbers of existing and new cases of HIV infection, the dental practitioner and other healthcare practitioners will still be required to treat oral and periodontal conditions unique to HIV/AIDS as well as conventional periodontal diseases in HIV-infected adults and children. The oral and periodontal conditions most closely associated with HIV infection include oral candidiasis, oral hairy leukoplakia, Kaposi's sarcoma, salivary gland diseases, oral warts, other oral viral infections, linear gingival erythema and necrotizing gingival and periodontal diseases. While the incidence and prevalence of these oral lesions and conditions appear to be declining, in part because of antiretroviral therapy, dental and healthcare practitioners will need to continue to diagnose and treat the more conventional periodontal diseases in these HIV-infected populations. Finding low-cost and easily accessible and acceptable diagnostic and treatment approaches for both the microbiological and the inflammatory aspects of periodontal diseases in these populations are of particular importance, as the systemic spread of the local microbiota and inflammatory products of periodontal diseases may have adverse effects on both the progression of HIV infection and the effectiveness of antiretroviral therapy approaches. Developing and assessing low-cost and accessible diagnostic and treatment approaches to periodontal diseases, particularly in developing countries, will require an internationally coordinated effort to design and conduct standardized clinical trials.

Abstract
Objectives: To study the prevalence of oral manifestations in HIV-infected patients and to correlate oral manifestations with age, gender, severity, and clinical staging. Materials and Methods: Fifty patients of either sex diagnosed as HIV positive were included in the study. The data obtained were analyzed statistically using Fisher's exact test and Chi-square test. Results: Among the 50 HIV-infected patients, oral manifestations were found in 40 (80.0%) patients. Thirty (60%) patients were seen in the age range between 31 and 65 years, and 29 (58%) patients were females. Majority of the patients [26 (52%)] were in the clinical staging C, of whom 23 (88.5%) were with manifestations with significant statistical value (P < 0.05). Patients with CD4 count less than 200 had manifestations in 22 (88%) patients. Correlation between reduction in CD4 count and presence of manifestations was significant (P < 0.05). Twenty-eight (80%) patients without antiretroviral therapy (ART) reported with manifestations. Correlation between ART and presence of manifestations was not significant (P = 1.00). Interpretation and Conclusion: Oral manifestations are the indicators for the disease progression. Clinical stage C and lower CD4 count may be useful predictors for HIV, with greater prevalence of oral manifestations.

Abstract
Human Immunodeficiency Virus (HIV)-related oral lesions can be used as markers of the immune status. The present cross-sectional study was conducted to identify the oral manifestations in HIV-infected individuals and their association with reduced Cluster of Differentiation 4 (CD4) count. The study population included known HIV-positive patients. A detailed case history of 399 HIV-positive patients was obtained and general examination was carried out. Diagnosis of oral lesions was done based on presumptive criteria of EEC Clearinghouse, 1993. The CD4 count was determined in 369 patients and correlated with oral manifestations. The prevalence of oral lesions was found to be 76.70% (n = 306). Oral candidiasis (157 (39.3%)) was the most common oral lesion associated with HIV infection. Amongst various forms of oral candidiasis, erythematous candidiasis (122 (39.3%)) outnumbered the other forms. The mean CD4 count of patients with oral lesions (207 cells/mm(3)) was less than in patients without oral lesions (291 cells/mm(3)) (P = 0.002). Oral candidiasis was found to be significantly correlated to a reduced CD4 cell count below 200 cells/mm(3) (P = 0.000; Odds ratio = 3.1; 95% Confidence interval 1.9-4.9) with good sensitivity, best specificity and positive predictive value. Oral manifestations may be used as an alternative to CD4 count at field-based settings to diagnose the immune compromised status of HIV-infected individuals.

Abstract
Background: Oral lesions are common among Human Immuno deficiency Virus (HIV)-positive patients. The pattern of oral features in these persons may differ in separate settings. Aims: To find out the spectrum of oral manifestations among a section of seropositive individuals attending the antiretroviral therapy (ART) centre of a referral hospital. Materials and Methods: A total of three hundred and twenty-one newly diagnosed seropositive patients were enrolled in this study. Of these, ninety-four patients who demonstrated lesions related to the oral cavity were examined intra-orally by a clinician. HIV testing was done with ELISA and CD4 counts were measured with the help of fluorescence activated cell sorter (FACS) system. Results: Fifty-four respondents presented exclusively with oral lesions. Candidiasis patients were the largest group (38.30%). Conclusion: HIV disease presents a plethora of oral manifestations, which provide valuable diagnostic and prognostic information.

Abstract
PURPOSE The purpose of this study is to review the Chinese-language medical and dental literature from 1982 to 2008 on oral manifestations (OMs) of patients with HIV/AIDS for introducing the spectrum of OMs of the patients in China. MATERIALS AND METHODS All data were extracted from 18 references which had used diagnostic criteria for HIV/AIDS. Four of the references had used the EC-Clearinghouse classification for oral lesions in HIV infection. The feasible overall rate and 95% confidence interval (95%CI) of the data on OMs were calculated. RESULTS Risk group analysis revealed that, of 203 patients, 64.3% were men and 35.7% were women (age range, 5 months to 64 years; mean age in three studies, 34.0, 34.3, and 36.1 years). Of these patients, 22.2% were infected by sexual contacts, 11.8% by intravenous drug use (IDU), 59.6% by blood or its products, 2.9% by mother to child transmission, and 3.4% were unclear. In 203 patients, oral candidiasis (OC) was the most common lesion (66%, 95%CI = 59.48-72.52%), followed by herpes simplex (HS) (22.2%, 95%CI = 16.48-27.92%), ulcerative stomatitis (14.8%, 95%CI = 9.92-19.68%), salivary gland disease (11.3%, 95%CI = 6.94-15.66%), oral hairy leukoplakia (OHL) (9.8%, 95%CI = 5.71-13.89%), necrotizing gingivitis (5.9%, 95%CI = 2.66-9.14%), Kaposi's sarcoma (2.9%, 95%CI = 0.59-5.21%), other malignant tumors (2.9%, 95%CI = 0.59-5.21%), and linear gingival erythema (2.0%, 95%CI = 0.07-3.93%). CONCLUSIONS The spectrum of OMs reported from China is similar to that described in the international literature. Present data are useful to supplement international resources of HIV/AIDS research.

Abstract
The purpose of this study was to evaluate the prevalence of oral lesions in HIV-positive patients attending the Specialized Service for Infectious-contagious Diseases and Parasitoses of the Health Secretariat of the State of Pará (URE-DIPE/SESPA), in the city of Belém, PA, Brazil. A total of 79 HIV-positive patients (53 males and 26 females) were examined. Clinical and epidemiological evaluations were done by correlating the lesions with gender, race, chronological age, risk behavior and prevailing immune status (CD4+ cells count). Lesion location and the presence of associated factors, such as alcohol use, smoking and denture wearing, were quantified individually for each type of lesion using a diagnostic pattern based on the clinical aspects. Approximately 47% of the patients (n=37) presented some type of oral lesion. Candidiasis (28%) and periodontal disease (28%) were the most common, followed by cervical-facial lymphadenopathy (17.5%). Other lesions observed were hairy leukoplakia, melanin hyperpigmentation, ulcerative stomatitis (aphthous), herpes simplex, frictional keratosis and pyogenic granuloma. This analysis presented some relevance as to the statistical data. Concerning CD4+ cells, most lesions manifested with the reduction of the CD count. There were a larger number of HIV-positive female heterosexual patients. Alcohol and/or smoking were strongly associated with the occurrence of hairy leukoplakia in these patients. Candidiasis and periodontal disease were the most common oro-regional clinical manifestations in the patients.

Abstract
Kaposi sarcoma (KS) is a multicentric angioproliferative disorder characterized by spindle cell proliferation, neo-angiogenesis, inflammation, and edema. Human herpesvirus (HHV)-8, a gamma-herpesvirus, is a critical factor, but is not alone sufficient for the initiation of KS. Other cofactors such as human immunodeficiency virus (HIV), host-derived cytokines, chemokines, and growth factors are required for the development of KS. Whether HIV-associated KS is a reactive hyperplastic inflammatory lesion or a true neoplasm is still controversial. It is likely that HIV-associated KS begins as a reactive disorder that in some cases progresses to a monoclonal, an oligoclonal, and a polyclonal neoplasm.

Abstract
OBJECTIVES To assess types and prevalence of HIV-related oral lesions among HIV-infected individuals in south India and to correlate common oral findings with co-morbidities, gender, age and medication. SUBJECTS AND METHODS One hundred and one patients with HIV infection or AIDS at infectious diseases units of Attavar Hospital, Mangalore, and medical wards of Kasturba Medical College, Manipal, were selected. Sociodemographic information was obtained using a structured questionnaire. Oral lesions were diagnosed according to the presumptive criteria of EEC-Clearinghouse Classification. Clinical history was retrieved from patient's medical records. RESULTS Erythematous candidiasis (44.5%), melanotic hyperpigmentaion (34.6%) and xerostomia (29.7%) were among the most common oral manifestations. A significant association was found between oral candidiasis and advanced immunosuppression (P < 0.05). Oral hairy leukoplakia (OHL) was predominant in individuals <35 years (P < 0.05). Melanotic hyperpigmentation was significantly associated with highly active antiretroviral therapy (P < 0.05). OHL was more frequent in patients with HIV-associated tuberculosis. Linear gingival erythema was more predominant in females. CONCLUSIONS Oral hairy leukoplakia showed a positive relationship with patients younger than 35 years. Oral candidiasis can act as a marker for immunosuppression. Angular cheilitis was predominant in the symptomatic stage.

Abstract
Although human immundeficiency virus (HIV) infection is endemic in Southeast Asia, data on oral mycotic flora in this disease in Asians are sparse. The aim of this study was to determine the prevalence of Candida species in HIV-infected Cambodians with oral candidosis, unexposed (group 1) and exposed to antimycotics (group 2) and a healthy population (group 3). In 161 HIV patients with oral candidosis (group 1: 121 pts; group 2: 40 pts) and in 81 controls (group 3) swab samples of tongue and palate were obtained. Oral candidosis was detected in 100 and 70% of groups 1 and 2 respectively. Candida spp. were isolated from 91 and 100% of groups 1 and 2, respectively, and from 79% of controls. Candida albicans was the most common, with non-albicans species such as C. tropicalis and C. krusei being notable. Our data indicate that variants of oral candidal infections in HIV disease are similar to those seen in the pre-HAART era. The particularly high rate of C. krusei isolation in all groups is noteworthy.

Abstract
HIV (ie, HIV-1) epidemics in Asia show great diversity, both in severity and timing. But epidemics in Asia are far from over and several countries including China, Indonesia, and Vietnam have growing epidemics. Several factors affect the rate and magnitude of growth of HIV prevalence, but two of the most important are the size of the sex worker population and the frequency with which commercial sex occurs. In view of the present state of knowledge, even countries with low prevalence of infection might still have epidemics affecting a small percentage of the population. Once HIV infection has become established, growing needs for care and treatment are unavoidable and even the so-called prevention-successful countries of Thailand and Cambodia are seeing burgeoning care needs. The manifestations of HIV disease in the region are discussed with the aim of identifying key issues in medical management and care of HIV/AIDS. In particular, issues relevant to developing appropriate highly active antiretroviral treatment programmes in the region are discussed. Although access to antiretroviral therapy is increasing globally, making it work effectively while simultaneously expanding prevention programmes to stem the flow of new infections remains a real challenge in Asia. Genuine political interest and commitment are essential foundations for success, demanding advocacy at all levels to drive policy, mobilise sufficient resources, and take effective action.

Abstract
AIM To determine the prevalence of dental and oral lesions, as well as treatment need, in a group of HIV sero-positive Brazilians. In addition, to test the association between oral manifestation of HIV infection and age, sex, mode of transmission and drug therapy. METHOD All HIV seropositive patients attending a dedicated dental clinic in Recife were invited to participate in the study. They were all examined by one trained and calibrated examiner and interviewed by one trained interviewer. RESULTS 161 of 204 patients (78.9%) agreed to participate in this study. Most of the participants were male (76%), had acquired HIV sexually (74.5%), and were taking some form of antiretroviral therapy (70.8%). 33.5% had one or more oral manifestation of HIV. Candidiasis was the most common (28.6%), followed by hairy leukoplakia (9.3%), Kaposi sarcoma (2.5%), ulceration (2.5%), herpes simplex (1.2%), papiloma (0.6%), and 4.4% had periodontal disease. Only 1.2% reported xerostomia. There were no differences in the prevalence of oral manifestations of HIV infection between age groups, sexes, modes of transmission and types of drug therapy (P>0.05). The mean DMF-T score was 19 (SD 8) and 78.9% needed some form of dental treatment. CONCLUSIONS While the prevalence of oral manifestations of HIV/AIDS was low in this sample of HIV seropositive Brazilians, dental status was poor and need for dental treatment was high.

Abstract
OBJECTIVES To assess prevalence and variations in the oral manifestations of HIV in HIV-infected subjects in southern Thailand (a new HIV epidemic) and northern Thailand (a mature epidemic), and the association with age, sex, risk behaviours, CD4 count and medication used. SUBJECTS AND METHODS A total of 102 and 135 HIV-infected individuals were enrolled in northern and southern hospitals, respectively. Oral and haematological examination was performed after sociodemographic interview of the patients. Clinical history was retrieved from patients' medical records. RESULTS Oral candidiasis (OC, 55%), oral hairy leucoplakia (OHL, 21%) and HIV-associated-periodontal disease (14%) were among the most common oral lesions in southern Thailand. OHL (38%), OC (25%), HIV-associated-periodontal disease (15%) were the three most common lesions in the north. A significant association was found between any oral lesion, OC, particularly the pseudomembranous type (PC), and CD4 < 200 cells mm(-3) at both sites. A negative relationship was found between systemic antifungal treatment and OC including PC and erythematous candidiasis (EC) in the southern data. OHL showed a positive relationship with male sex and a negative relationship with antiretroviral treatment in the northern site. Younger age and being a current smoker were positively associated with oral lesions in the southern group. CONCLUSION OC, particularly PC, could be useful as a marker for immunosuppression, particularly where CD4 count cannot be determined routinely. Antifungal treatment is of benefit in the subjects who cannot afford highly active antiretroviral therapy (HAART).

Abstract
OBJECTIVE To document the prevalence, age and gender distribution and clinical features of HIV/AIDS orofacial lesions in patients referred to the two largest Oral and Maxillofacial specialist centers in Harare, Zimbabwe, and compare the findings with those from other parts of the world. DESIGN Descriptive study. SETTING Oral and Maxillofacial Surgical Clinics at specialist referral hospitals; Harare Central Hospital and Parirenyatwa Government Hospital, Harare, Zimbabwe. SUBJECTS A total of 7800 consecutive patients referred for various orofacial conditions were examined. From this group, 156 patients with orofacial lesions of or suggestive of HIV/AIDS were further interviewed and examined by the oral and maxillofacial surgeon in charge of the clinics. METHODS Head, neck and oral examinations were carried out. Oral examination was carried out using mouth mirror and dental light in a dental chair. HIV/AIDS orofacial lesions were recorded and diagnosed using the EC Clearing House Criteria on Oral Problems related to HIV Infection (1993). RESULTS There were 79 males and 77 females. Male:female ratio 1:1; age range 1-56 years; candidiasis (55.1%) was the most common lesion with the pseudomembranous type (55.8%) predominating. High prevalences of Kaposi's sarcoma (18.6%), salivary gland disease (12.2%) and cancrum oris (3.8%) were noted. Heterosexual contact and mother to child transmissions appear to be the mode of transmission. CONCLUSION The spectrum of orofacial lesions is similar to that in other countries. This study shows a high prevalence of candidiasis, Kaposi's sarcoma, salivary gland disease, non-Hodgkin's lymphoma, cancrum oris and rampant caries.

Abstract
Oral candidiasis is the most common opportunistic infection in individuals infected with the human immunodeficiency virus. Though Candida albicans is the major aetiological agent, non-albicans species such Candida tropicalis are now emerging as important agents of such infection. The Candida cell surface hydrophobicity (CSH) is considered a critical factor contributing to its colonization potential and virulence. It is also known that brief exposure to sub-cidal concentrations of antifungal agents is a likely scenario in the oral environment where the administered drugs are diluted continuously due to the flushing action of saliva. Hence the objective of the present study was to compare the CSH of 10 isolates each of C. albicans and C. tropicalis from HIV-infected individuals following brief exposure (1 hour) of isolates to sub-therapeutic concentrations of nystatin, amphotericin B, ketoconazole, fluconazole and 5-flurocytosine. The CSH was assessed by a previously described biphasic aqueous-hydrocarbon assay. The mean percentage reduction of CSH of C. albicans following brief exposure to nystatin, amphotericin B, ketoconazole, fluconazole and 5-flurocytosine was 27.33 (p < 0.001), 21.34 (p < 0.05), 11.74 (p > 0.05), 18.4 (p > 0.05) and 14.64 (p > 0.05) respectively. The mean percentage reduction of CSH of C. tropicalis following brief exposure to nystatin, amphotericin B, ketoconazole, fluconazole and 5-flurocytosine was 33.81 (p < 0.01), 28.88 (p < 0.01), 12.6 (p > 0.05), 21.53 (p > 0.05) and 17.68 (p > 0.05) respectively. A significant interspecies variation in CSH was observed for nystatin and amphoterecin B. Overall the results reveal that the CSH of C. albicans is affected to a significantly lesser degree compared with C. tropicalis when exposed to the antifungals. These data further illustrate another mode of action of antifungals on Candida leading to a reduction in the CSH and thereby the yeast adherence to host tissues.

Abstract
OBJECTIVES An International Workshop addressed the prevalence and classification of HIV/ AIDS associated oral lesions. DESIGN Five questions provided the framework for discussion and literature review. What is the prevalence of oral lesions in children and adults? Should the accepted classification of HIV-related oral lesions be modified in the light of recent findings? Why is there a gender difference in the prevalence of oral lesions in developed and developing countries? Are there unusual lesions present in developing countries? Is there any association between modes of transmission and the prevalence of oral lesions? RESULTS Workshop discussion emphasized the urgent need for assistance in the development of expertise to obtain accurate global prevalence data for HIV-associated oral lesions. Oral candidiasis has been consistently reported as the most prevalent HIV-associated oral lesion in all ages. Penicilliosis marneffei, a newly described fungal infection, has emerged in South-east Asia. Oral hairy leukoplakia and Kaposi's sarcoma appear to be associated with male gender and male-to-male HIV transmission risk behaviours. These lesions occur only rarely in children. CONCLUSIONS Additional prevalence data are needed from developing countries prior to substantially altering the 1993 ECC/WHO Classification of oral lesions associated with adult HIV infection. The workshop confirmed current oral disease diagnostic criteria.

Abstract
HIV infection has spread rapidly within developing countries since it was first recognized in the early 1980s. The purpose of this paper is to review the prevalence of oral lesions associated with HIV infection (oral HIV) in the developing world, and to identify additional factors that may complicate the presentation of these lesions. Direct comparison of regional and local prevalence studies within Africa, India and Thailand is speculative because there are few reports available. Furthermore, inherent differences in study design, data collection, standardization and calibration of health workers make any inferences inconclusive. Additional prevalence studies of oral HIV lesions associated with systemic disease or social conditions, such as poverty or malnutrition, are needed. In order to provide a basis for the diagnosis and treatment of HIV-associated oral lesions in the developing world, it is important to recognize any confounding factors that may impact on their presentation and management. Elucidation of these various factors may provide a basis for treatment within the developing and developed world.

Abstract
BACKGROUND High viral load is currently considered to be one of the main indicators of the progression of HIV-induced immunodepression, but few studies have analysed its relationship to the presence of oral candidiasis (OC). The aim of this cross-sectional study is to analyse the relationship between viral load, total CD4 lymphocyte count, and percentage of CD4 lymphocytes to the occurrence of OC. METHODS The present cross-sectional study included 156 HIV-infected patients seen at a clinic for sexually transmitted diseases and HIV. We assessed the presence or absence of OC, and microbiological samples were obtained from the palatine mucosa and dorsal tongue for a smear stained with KOH (potassium hydroxide) and culture on Sabouraud's dextrose agar in all patients. Viral load was determined by quantification of viral RNA in peripheral blood with a minimum detectable level of 500 RNA copies/ml. CD4+ counts/CD4+ percentage were categorized as <200/<14%, 200-499/14-28%, and >500/>29%, and HIV viral loads were categorized as <500, 500-10,000, >10,000 copies/ml. RESULTS Thirty-eight percent (37.8%) of the patients had OC. Patients with CD4+ lymphocyte counts below 200 x 10(6)/l and CD4+ percentages below 14% showed a significantly higher frequency of OC (57.9% and 48.0%, respectively). Patients with a viral load over 10,000 copies/ml also had OC more frequently (44.8%). In the multiple logistic regression analysis, OC showed a statistically significant association with high viral load [>10,000 vs <500, odds ratio (OR)=11.4], low percentage of CD4+ lymphocytes (<14% vs >28%, OR=5), and injection drug use (IDU vs heterosexual transmission, OR=10.2). In HIV-infected patients, high viral load was associated with more frequent OC, regardless of CD4+ lymphocyte level. CONCLUSIONS These findings suggest that oral candidiasis could be a useful clinical marker of patients with high viral load. In view of these results, emphasis should be placed on the importance of systematic examination of the oral cavity in all medical follow-up examinations of HIV-infected patients.

Abstract
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.

Abstract
A range of oral mucosal and periodontal lesions is associated with HIV infection and HIV disease progression. These are often symptomatic and require treatment in themselves, and also have a diagnostic and prognostic role in the management of the underlying HIV disease. These lesions have been broadly divided into: (a) those strongly associated with HIV such as oral candidoses, oral hairy leukoplakia and Kaposi's sarcoma; (b) those less strongly associated such as swellings of the major salivary glands; and (c) those least commonly associated such as recurrent aphthous ulcers. Overall the prevalence and severity of these lesions inversely correlate with the level of immunosuppression. With the passage of time, there has been improved understanding of the disease pathogenesis resulting in the development of new drugs to combat this infection. Medication has changed from monotherapy to current triple combination therapy (Highly Active Anti-Retroviral Therapy). This review looks at the impact of changing therapy on the prevalence of the various oral lesions associated with HIV. It finds a decrease in the prevalence of the oral lesions in the era of combination therapy as compared to earlier periods. It also shows a change in the types of lesions which predominate with those previously placed amongst the strongly associated lesions no longer being predominant in the era of combination therapy where such treatment is available.

Abstract
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.

Abstract
A total of 32 HIV-infected, predominantly ethnic Chinese individuals from Hong Kong were examined for oral mucosal lesions over a period of 1 year. The commonest oral lesion found was minor aphthous ulceration (27.4%), while xerostomia (17.8%), ulceration NOS (not otherwise specified; 12.3%), hairy leukoplakia (11.0%) and erythematous candidiasis (6.9%) were less frequent; Kaposi's sarcoma was notable for its absence. When the relationship between the number of oral lesions with age, risk group, medication taken, CDC staging and CD4+ count of the study group was investigated, a significantly higher number of oral lesions was associated with use of AZT, homosexuals and CDC stage IV; in contrast, a smaller number of lesions was found in those on antiparasitics and multivitamins (all P<0.05). When compared with studies from other parts of the world, the frequency of oral lesions appeared to be less common in the current study group. However, due to a lack of similar studies from the Asian region, especially in ethnic Chinese, it is not clear whether this difference could be attributed to racial, social or geographic factors.

Abstract
A cross-sectional analysis was conducted in Mexico City from September 1989 to March 1996, to determine the prevalence of HIV-related oral manifestations by gender and route of HIV transmission. The diagnosis of HIV-associated oral lesions was based on preestablished criteria. For the statistical analysis chi-squared and Fisher's exact tests were used where appropriate. Odds ratios were calculated as estimates of the relative risks. Control of confounding factors was performed by logistic regression models. Oral lesions were present in 75% of 436 HIV+ patients. Hairy leukoplakia, erythematous and pseudomembranous candidosis, angular cheilitis and oral ulcers were frequently found. Patients who contracted HIV through blood transfusion were more likely to present erythematous candidosis (P=0.005) than subjects who acquired HIV through sexual transmission. Oral ulcers were seen only in men (P=0.02) and in individuals who contracted HIV through sexual transmission (P=0.02). This study brings valuable data in regard to differences in the type and prevalence of HIV-related oral lesions by gender and the risk categories analysed, particularly blood transfusion.
