Abstract
BACKGROUND Human Papillomavirus-32 (HPV-32) has traditionally been associated with focal-epithelial-hyperplasia (FEH). It is also present in 58% of oral warts of HIV-positive individuals whose prevalence is increasing. Current methods for the detection of HPV-32 are labor-intensive and insensitive so the goal of this work was to develop a highly sensitive and easy to use specific polymerase chain reaction (PCR) assay. MATERIALS AND METHODS An HPV-32 L1 specific PCR assay was developed and optimized. The sensitivity and specificity was compared to previous assays utilized for detection (PGMY and MY09/11 PCR with dot blot hybridization) using cloned HPV-32 L1, the closely related HPV-42 L1 as well as clinical samples (oral swabs and fluids from 89 HIV-positive subjects). RESULTS The HPV-32 specific PCR assay showed improved sensitivity to 5 copies of HPV-32 as compared to the PGMY PCR, MY09/11 PCR and dot blot which had a limit of detection of approximately 3,000 copies. Using the HPV-32 dot blot hybridization assay as the gold standard, the HPV-32 specific PCR assay has a sensitivity of 95.8% and 88.9% by sample and subject, respectively, and specificity was 87.8% and 58.8% by sample and subject, respectively. The low sensitivity is due to the HPV-32 specific PCR assays ability to detect more HPV-32 positive samples and may be the new gold standard. CONCLUSION Due to the ease, sensitivity, and specificity the HPV-32 specific PCR assay is superior to previous assays and is ideal for detection of HPV-32 in large cohorts. This assay provides an excellent tool to study the natural history of HPV-32 infection and the development of oral warts.

Abstract
Human immunodeficiency virus (HIV)-related cutaneous and anogenital disease in the highly active antiretroviral therapy (HAART) era presents challenging problems for dermatologists. Immune reconstitution-associated diseases (IRADs) are common and important consequences of HAART. Dermatologists should be aware of the cutaneous manifestations of IRAD. The prevalence of clinical human papillomavirus (HPV)-related disease is increased in HIV and does not appear to be diminished by HAART. Many patients on HAART are dogged by persistent cutaneous warts. Anogenital precancer is also common in HIV and may be burgeoning with HAART. Clinicians should be aware of the increased risk of cervical, penile and vulval/vaginal cancers in treated and untreated patients with HIV. The increase in HPV infection in HIV-infected individuals may be, at least partly, due to increased exposure to diverse HPV types, particularly high-risk types that might be able to persist for longer in anogenital regions. Alternatively, persistent/emergent HPV disease in HIV infection might represent persistent or modulated immunodysregulation after HAART and be viewed as a form of IRAD. The immunopathogenesis of HPV IRAD is fascinating and possibly determined by host genotype.

Abstract
As the highly active antiretroviral therapy (HAART) has transitioned human immunodeficiency virus (HIV) infection into a 'chronic disease' management strategy, there is growing evidence that infection with non-HIV pathogens in HIV+ patients may have important public health implications in undermining HAART success and acquired immunodeficiency syndrome progression. Several bacterial and host cell products during infections with non-HIV pathogens have shown the capacity to regulate HIV replication in latently infected cells. A high prevalence of oral infections caused by bacteria, viruses and fungi has been described in HIV+ patients, including periodontal disease. The oral cavity appears to be a site of HIV pathogenesis and potential reservoir for the disease as HIV RNA and DNA forms are present in saliva as well as in gingival crevicular fluid, and oral epithelial cells are susceptible to either cell free or cell-associated HIV infection. The clinical and biological bases of potential associations between chronic oral inflammatory disorders, such as periodontal disease, and exacerbation of HIV viraemia have received little attention. This review attempts to evaluate the current understanding of HIV reactivation as a result of co-infection and/or inflammation induced by non-HIV pathogens in HIV-infected patients, and presents a hypothetic model about the potential role of periodontitis as a global oral infection that potentially contributes to HIV recrudescence.

Abstract
The use of antiretroviral therapy (ART) to treat HIV infection, by restoring CD4+ cell count and immune function, is associated with significant reductions in morbidity and mortality. Soon after ART initiation, there is a rapid phase of restoration of pathogen-specific immunity. In certain patients, this results in inflammatory responses that may result in clinical deterioration known as 'the immune reconstitution inflammatory syndrome' (IRIS). IRIS may be targeted at viable infective antigens, dead or dying infective antigens, host antigens, tumour antigens and other antigens, giving rise to a heterogeneous range of clinical manifestations. The commonest forms of IRIS are associated with mycobacterial infections, fungi and herpes viruses. In most patients, ART should be continued and treatment for the associated condition optimized, and there is anecdotal evidence for the use of corticosteroids in patients who are severely affected. In this review, we discuss research relating to pathogenesis, the range of clinical manifestations, treatment options and prevention issues.

Abstract
In order to verify possible association between immune reconstitution inflammatory syndrome (IRIS) and oral manifestations (OMs), we selected AIDS patients who had low CD4 count before the initiation of highly active antiretroviral therapy (HAART) and who returned three months later for therapy evaluation. The oral lesions observed three months after the initiation of HAART were evaluated and associated with the type of antiretroviral therapy (ART), CD4 count and HIV-RNA load levels (before and three months after HAART initiation). A total of 105 patients matched the selected criteria. Immune reconstitution (IR) was identified in 35.2%. Among these patients, the mean CD4 cell count rose from 105.97 to 330.29 and the mean viral load dropped from 168.005 (log 5.22) to 21.852 (log 4.33). There was no significant difference in age (P = 0.78), sex (P = 0.41) or previous history of ART (P = 0.55) between IR and non-IR patients. In the IR group, the most common OM was parotid enlargement (57.14%) (P = 0.019), whereas in the non-IR group candidiasis (46.15%) was the most common OM. The results of our study suggest that the parotid gland enlargement found in the studied population might be an IRIS event, as it was found in patients with IR three months after the initiation of HAART.

Abstract
Human papillomavirus (HPV) infection is etiologically associated with a subset of oral cancers, and yet, the natural history of oral HPV infection remains unexplored. The feasibility of studying oral HPV natural history was evaluated by collecting oral rinse samples on 2 occasions at a 6-month interval from 136 HIV-positive and 63 HIV-negative participants. Cervical vaginal lavage samples were concurrently collected for comparison. HPV genomic DNA was detected in oral and cervical samples by consensus primer PCR and type-specified for 37 HPV types. The six-month cumulative prevalence of oral HPV infection was significantly less than for cervical infection (p < 0.0001). HIV-positive women were more likely than HIV-negative women to have an oral (33 vs. 15%, p = 0.016) or cervical (78 vs. 51%, p < 0.001) infection detected. Oral HPV infections detected at baseline were as likely as cervical infections to persist to 6 months among HIV-negative (60% vs. 51%, p = 0.70) and HIV-positive (55% vs. 63%, p = 0.27) women. Factors that independently elevated odds for oral HPV persistence differed from cervical infection and included current smoking (OR = 8, 95% CI = 1.3-53), age above 44 years (OR = 20, 95% CI = 4.1-83), CD4 < 500 (OR = 6, 95% CI = 1.1-26), use of HAART therapy (OR = 12, 95% CI = 1.0-156), and time on HAART therapy (trend p = 0.04). The rate of oral HPV infections newly detected at follow-up was significantly lower than cervical infection among HIV-positive (p < 0.001) and HIV-negative women (p < 0.001). Our study not only demonstrates that it is feasible to study the natural history of oral HPV infection with oral rinse sampling, but also indicates that oral and cervical HPV natural history may differ.

Abstract
OBJECTIVE To determine the prevalence of oral lesions associated with human immunodeficiency virus (HIV) in a population of dental patients and analyze its association with psycho-social variables and biological markers. STUDY DESIGN The dental charts of 415 dental patients consecutively treated between May and July 2005 in a dedicated HIV dental clinic were reviewed. Oral soft tissue examinations, psycho-social and medical variables were extracted and recorded for each patient. Ethnicity, gender, HIV treatment, peripheral CD(4) counts and tobacco usage were analyzed in correlation with oral lesions associated with HIV. RESULTS Fifty-five percent of all subjects had at least one oral lesion associated with HIV, with oral candidiasis, salivary gland enlargement and oral hairy leukoplakia being the most commonly observed conditions. Gender and ethnicity did not correlate with a higher prevalence in lesions. However, tobacco smoking correlated significantly with a higher prevalence of oral lesions, independent of CD(4) counts. CONCLUSIONS These findings suggest that oral lesions remain commonly observed morbidities among HIV-infected dental patients independent of gender and ethnicity and that tobacco usage is a major and often underestimated risk factor for those lesions.

Abstract
BACKGROUND The advent of highly active antiretroviral therapy (HAART) has changed the scenario of human immunodeficiency virus (HIV) infection. HIV patients in India have now access to generic HAART and this is the first report describing oral lesions in patients on HAART from our country. METHODS Oral lesions were studied in HIV seropositive patients (n = 50 on HAART and n = 50 not on HAART) attending a tertiary HIV referral care centre in India and patients on HAART were followed up. RESULTS There was a difference in the occurrence of oral candidiasis (OC) between HAART and non-HAART participants (8%, 24%; P < 0.05). Pseudomembranous candidiasis was 4% and 18% in HAART and non-HAART groups respectively (P < 0.05). In patients with CD4 count <or=200, OC was 5.6% in the HAART group and 39.1% in the non-HAART group (P < 0.05). Among patients with CD4 count >200, pigmentation was 43.8% in the HAART group and 14.8% in the non-HAART group (P < 0.05). CONCLUSION The prevalence of OC in patients who had access to HAART was less when compared with those who did not have access to HAART.

Abstract
HPV infection of both the genital tract and oral cavity of HIV+ men and women is increased. HPV-related pathology is also increased in the HIV+ individuals, usually with further increases seen for those HIV+ individuals with lower CD4 cell counts. Fortunately, the rates of cervical cancer and anal cancer are relatively low and not related to CD4 cell count. Treatment of the HIV+ individual with HPV-related disease is challenging and requires close long-term follow-up to prevent recurrent disease. The mechanism of how HPV and HIV interact is still not known but is more likely to be linked to immune suppression rather than a direct interaction between viruses. The newly developed HPV vaccines will likely have a significant impact on HPV-related disease in immunocompetent individuals. It remains to be seen what impact these vaccine will have on the immune depressed.

Abstract
The immune reconstitution inflammatory syndrome (IRIS) represents a diverse range of immunopathologic reactions resulting in clinical deterioration that may occur as immune function is partially restored in HIV-infected patients receiving highly active antiretroviral therapy. Approximately half of IRIS events are dermatologic, and dermatologic IRIS is described in relation to a wide range of conditions, the commonest being herpes zoster and herpes simplex. Most cases of IRIS result in mild and moderate symptoms, but non-dermatologic manifestations related to IRIS have resulted in death. This article covers certain general issues related to IRIS and then focuses on the spectrum of dermatologic manifestations.

Abstract
BACKGROUND The aim of the study was to compare the prevalence and types of HIV-related oral lesions between children and adult Tanzanian patients on HAART with those not on HAART and to relate the occurrence of the lesions with anti-HIV drug regimen, clinical stage of HIV disease and CD4+ cell count. METHODS Participants were 532 HIV infected patients, 51 children and 481 adults, 165 males and 367 females. Children were aged 2-17 years and adults 18 and 67 years. Participants were recruited consecutively at the Muhimbili National Hospital (MNH) HIV clinic from October 2004 to September 2005. Investigations included; interviews, physical examinations, HIV testing and enumeration of CD4+ T cells. RESULTS A total of 237 HIV-associated oral lesions were observed in 210 (39.5%) patients. Oral candidiasis was the commonest (23.5%), followed by mucosal hyperpigmentation (4.7%). There was a significant difference in the occurrence of oral candidiasis (chi2 = 4.31; df = 1; p = 0.03) and parotid enlargement (chi2 = 36.5; df = 1; p = 0.04) between children and adults. Adult patients who were on HAART had a significantly lower risk of; oral lesions (OR = 0.32; 95% CI = 0.22-0.47; p = 0.005), oral candidiasis (OR = 0.28; 95% CI = 0.18-0.44; p = 0.003) and oral hairy leukoplakia (OR = 0.18; 95% CI = 0.04-0.85; p = 0.03). There was no significant reduction in occurrence of oral lesions in children on HAART (OR = 0.35; 95% CI = 0.11-1.14; p = 0.15). There was also a significant association between the presence of oral lesions and CD4+ cell count < 200 cell/mm3 (chi2 = 52.4; df = 2; p = 0.006) and with WHO clinical stage (chi2 = 121; df = 3; p = 0.008). Oral lesions were also associated with tobacco smoking (chi2 = 8.17; df = 2; p = 0.04). CONCLUSION Adult patients receiving HAART had a significantly lower prevalence of oral lesions, particularly oral candidiasis and oral hairy leukoplakia. There was no significant change in occurrence of oral lesions in children receiving HAART. The occurrence of oral lesions, in both HAART and non-HAART patients, correlated with WHO clinical staging and CD4+ less than 200 cells/mm3.

Abstract
Bowenoid papulosis (BP) is a condition triggered by human papillomavirus infection and characterized by the development of 1 or more warty lesions, usually in the anogenital region. Although the oral cavity has been known to host several types of warts, thus far only 4 cases of BP have been reported in this anatomic site. We describe a 42-year-old male with AIDS who presented with numerous papillary lesions of the labial mucosa and vermilion. Biopsy yielded a diagnosis of BP. Treatment of the condition consisted of intralesional and subcutaneous injections of interferon-alpha followed by topical application of imiquimod 5% cream. Neither regimen resulted in resolution of the lesions. To our knowledge, this represents the first case of BP arising in the oral mucosa of an HIV-infected individual.

Abstract
BACKGROUND Prevalence of human papillomavirus (HPV)-associated oral condylomas has reportedly increased in HIV-infected individuals since the introduction of highly active antiretroviral therapy (HAART). The relationships between HIV therapy regimen, overall health, and subclinical oral HPV have not been examined. GOAL To determine oral HPV genotype prevalence and the impact of HAART and health in the HIV+ population. STUDY An L1 consensus-primer polymerase chain reaction and linear array assay were used to examine the prevalence of 27 HPV genotypes in saliva of 98 HIV+ individuals. Risk assessment variables were compared to oral HPV status. RESULTS Oral HPV was detected in 37% of HIV+ African American individuals. Caucasians were at greater risk of oral HPV infection than African Americans. Markers of advanced HIV disease did not predict HPV status. Therapy status was associated with HPV detection.

Abstract
HIV infection affects residents of all countries of the world, but the greater majority of affected individuals reside in the developing world. In the past decade there have been substantial changes in the management of HIV disease, particularly the introduction of highly active antiretroviral therapy (HAART). Such agents have reduced significantly the morbidity and mortality associated with HIV disease, however, they are not available for most HIV-infected individuals in the developing world. There is now considerable understanding of the molecular epidemiology, transmission and therapy of the common opportunistic oral infections of HIV disease, and as a consequence of improved anti-HIV strategies, the frequency and severity of oral disease associated with HIV infection have reduced considerably, although HAART may predispose to human papilloma virus infection of the mouth and potentially increase the risk of later oral squamous cell carcinoma. Despite advances in clinical care the majority of individuals with HIV disease worldwide will continue to develop oral disease, as they are resident in the developing world and do not have ready access to even simple therapies.

Abstract
In the last 10 years, interesting results have been reported concerning the impact of highly active antiretroviral therapy (HAART) on the changing pattern of organ‐specific manifestations of HIV‐1 infection. There has been a clear step‐wise reduction in the incidence of several opportunistic infections (OIs), particularly Pneumocystis carinii pneumonia, whereas a nonsignificant reduction in incidence has been observed for other organ‐specific diseases, including invasive cervical cancer and Hodgkin disease. In addition, several organ‐specific manifestations, including HIV‐associated nephropathy, wasting syndrome and cardiomiopathy, are a direct consequence of damage by HIV‐1, and so HAART may have a therapeutic effect in improving or preventing these manifestations. Finally, the introduction of HAART has seen the emergence of several complications, termed immune reconstitution inflammatory syndrome, which includes OIs such as cytomegalovirus vitritis, Mycobacterium avium complex lymphadenitis, paradoxical responses to treatment for tuberculosis, and exacerbation of cryptococcosis. Because not all HIV‐1 organ‐specific manifestations are decreasing in the HAART era, this review will analyse the influence of HAART on several organ‐specific manifestations, and in particular OIs related to several organs, cerebral disorders and HIV‐1‐related neoplasia.

Abstract
BACKGROUND Oral warts, caused by human papillomavirus (HPV), and oral hairy leukoplakia (OHL) caused by Epstein-Barr virus (EBV), are common oral manifestations in HIV-infected persons. Although both conditions occur most often with reduced blood CD4+ T-cell numbers, oral warts and OHL rarely occur simultaneously, suggesting that dysfunctions in other secondary local immune parameters are also involved. The present study evaluated tissue-associated proinflammatory and T-helper cytokine and chemokine mRNA expression and the presence of T cells in each lesion. METHODS Biopsies were taken from lesion-positive and adjacent lesion-negative sites of HIV+ persons with oral warts or OHL and lesion-negative sites from HIV+ persons who were oral HPV or EBV DNA-positive (matched controls). Cytokine/chemokine mRNA expression was quantified by real-time polymerase chain reaction. CD3, CD4, and CD8 cells were identified by immunohistochemistry. RESULTS No differences were detected in tissue-associated cytokine/chemokine mRNA expression in warts or OHL when compared to lesion-negative sites. Immunohistochemical analysis of T cells showed CD8+ cells exclusively, but few cells were present in either lesion. No differences were detected between lesion-positive and -negative control sites of each pathologic condition. CONCLUSION Little evidence was found for local immune reactivity to either oral warts and OHL, suggesting that CD4+ T cells are a primary host defense against both oral warts and OHL, but with nonimmune factors potentially responsible for the divergent prevalence of each.

Abstract
OBJECTIVES Several types of HIV-related oral mucosal conditions have been reported to occur during the course of HIV disease progression. Of these, few may be manifested as 'white' lesions and many are noticeable to the patient. This paper examines the relationships between social, behavioral and medical aspects of HIV infection and reporting an occurrence of oral white patches (OWP) by HIV-infected patients. METHODS The subjects are participants in all three interviews in the HIV Cost and Services Utilization Study (HCSUS). The subjects were selected using a three-stage probability sampling design. The multivariate analysis is based on 2109 subjects with nonmissing binary outcome variable for all three waves representing a national sample of 214 000 individuals. The multivariate model was fitted using generalized estimating equations (GEE) by implementing the XTGEE command in STATA. RESULTS We estimate that 75 000 persons (35%) reported at least one incident of OWP, of these 14 000 reported having OWP during all three interviews, and that the rate of reporting declined over the three HCSUS waves. The multivariate analysis showed seven variables that were significant predictors of at least one report of OWP. CONCLUSIONS Compared with persons on HAART therapy, patients on other regimens or taking no antiviral medications were 23-46% more likely to report an incident of OWP. Compared with whites, African Americans were 32% less likely to report OWP, while current smokers were 62% more likely than nonsmokers. Being diagnosed with AIDS and having CD4 counts less than 500 significantly increased the likelihood of reporting OWP.

Abstract
This longitudinal study examines perceived unmet dental need in a nationally representative probability sample of HIV-infected persons in medical care. A logistic regression analysis modeled the relationship between unmet need and explanatory variables. We estimate that 40% of HIV/AIDS patients report an unmet need associated with being male, being unemployed, injecting drugs, being heterosexual, lacking dental insurance, and having less education. Disparities in unmet need are related to socioeconomic status rather than to disease stage or ethnicity.

Abstract
OBJECTIVE Study the prevalence of potentially pathogenic microorganisms in saliva of HIV-positive women in the Women's Interagency HIV Study. STUDY DESIGN 157 HIV-positive and 31 HIV-negative women were studied. At baseline and every 6 months over 4 years, information was collected on socioeconomic and educational status, oral and systemic health, including HIV markers and antiretroviral therapy, and frequency of professional oral care utilization. Bacterial and yeast pathogenic isolates from stimulated whole saliva were tentatively identified using standard methodologies. RESULTS The prevalence of microorganisms in stimulated saliva of HIV-positive women was not significantly different from that of HIV-negative women. In HIV-positive women, highly active antiretroviral therapy (HAART) was independently and significantly associated with the presence of a variety of salivary bacterial species. HAART increased the risk for recovering Fusobacterium species (P < .001), enteric gram-negative rods (P < .05), Peptostreptococcus micros (P < .05), Campylobacter species (P < .0001), Eubacterium species (P < .001), and Tannerella forsythia (P < .01). In contrast, HAART led to decreased recovery rate of yeasts (Candida albicans and Candida dubliniensis) (P < .0001). CONCLUSION The present findings suggest that the institution of HAART promotes an increasingly pathogenic salivary microbiota, at least temporarily. Similar findings have been reported for various nonoral microbial ecosystems.

Abstract
Some individuals who initiate highly active antiretroviral therapy (HAART) develop new or worsening opportunistic infections or malignancies despite improvements in surrogate markers of HIV-1 infection. These events of paradoxical clinical worsening, also known as immune reconstitution syndromes (IRS), are increased in individuals with prior opportunistic infections or low CD4+ T-cell nadirs. They are thought to result from reconstitution of the immune system's ability to recognize pathogens or tumor antigens that were previously present, but clinically asymptomatic. There is no consensus regarding the diagnostic criteria or pathogenesis of IRS. Knowledge of their presentation and treatment is largely based on case reports. With the introduction of HAART into resource-limited settings, it is likely that significantly more and distinct forms of IRS will be observed. Prospective studies of the incidence and treatment of IRS in multiple settings are critical to better understand their pathogenesis and optimal management.

Abstract
Human papilloma virus (HPV) causes focal infections of epithelial layers in skin and mucosa. HIV-infected patients on highly active antiretroviral therapy (HAART) appear to be at increased risk of developing HPV-induced oral warts. To identify the mechanisms that allow long-term infection of oral epithelial cells in these patients, we used a combination of laser-dissection microscopy (LDM) and highly sensitive and quantitative, non-biased, two-step multiplex real-time RT-PCR to study pathogen-induced alterations of specific tissue subcompartments. Expression of 166 genes was compared in three distinct epithelial and subepithelial compartments isolated from biopsies of normal mucosa from HIV-infected and non-infected patients and of HPV32-induced oral warts from HIV-infected patients. In contrast to the underlying HIV infection and/or HAART, which did not significantly elaborate tissue substructure-specific effects, changes in oral warts were strongly tissue substructure-specific. HPV 32 seems to establish infection by selectively enhancing epithelial cell growth and differentiation in the stratum spinosum and to evade the immune system by actively suppressing inflammatory responses in adjacent underlying tissues. With this highly sensitive and quantitative method tissue-specific expression of hundreds of genes can be studied simultaneously in a few cells. Because of its large dynamic measurement range it could also become a method of choice to confirm and better quantify results obtained by microarray analysis.

Abstract
The possibility of increases in both oral and anogenital pathologic conditions due to human papillomavirus (HPV) in patients infected with the human immunodeficiency virus (HIV) is of concern and is the focus of numerous current research studies. HIV-infected women are at higher risk for cervical HPV detection, for infection with high-oncogenic-risk types of HPV, for persistent HPV infection, for cervical cytologic abnormalities, and for cervical intraepithelial neoplasms. HIV-infected men are at increased risk for anal HPV infection, for anal infection with high oncogenic-risk types of HPV, for persistent anal HPV infection, and for anal intraepithelial defects. Recent studies have shown an increased risk of oral warts in HIV-infected individuals despite treatment with highly active antiretroviral therapy (HAART). Oral HPV infection rates have not declined since the initiation of HAART, and evidence suggests that the rates may have actually increased in white HIV-infected males.

Abstract
Suppression of HIV replication by highly active antiretroviral therapy (HAART) often restores protective pathogen-specific immune responses, but in some patients the restored immune response is immunopathological and causes disease [immune restoration disease (IRD)]. Infections by mycobacteria, cryptococci, herpesviruses, hepatitis B and C virus, and JC virus are the most common pathogens associated with infectious IRD. Sarcoid IRD and autoimmune IRD occur less commonly. Infectious IRD presenting during the first 3 months of therapy appears to reflect an immune response against an active (often quiescent) infection by opportunistic pathogens whereas late IRD may result from an immune response against the antigens of non-viable pathogens. Data on the immunopathogenesis of IRD is limited but it suggests that immunopathogenic mechanisms are determined by the pathogen. For example, mycobacterial IRD is associated with delayed-type hypersensitivity responses to mycobacterial antigens whereas there is evidence of a CD8 T-cell response in herpesvirus IRD. Furthermore, the association of different cytokine gene polymorphisms with mycobacterial or herpesvirus IRD provides evidence of different pathogenic mechanisms as well as indicating a genetic susceptibility to IRD. Differentiation of IRD from an opportunistic infection is important because IRD indicates a successful, albeit undesirable, effect of HAART. It is also important to differentiate IRD from drug toxicity to avoid unnecessary cessation of HAART. The management of IRD often requires the use of anti-microbial and/or anti-inflammatory therapy. Investigation of strategies to prevent IRD is a priority, particularly in developing countries, and requires the development of risk assessment methods and diagnostic criteria.

Abstract
Human papillomavirus (HPV) infections play an important role in the pathogenesis of anogenital cancer and its precursors. HIV-infected individuals exhibit a high prevalence of HPV DNA. Several studies have further shown that HIV-infected individuals have an increased prevalence of squamous intraepithelial lesions (SIL) of the cervix, vulva and anus. The incidence of invasive cervical cancer is also elevated in HIV-positive women as well as that of anal cancer in HIV-positive women and men. Given the relationship between HIV-induced immunosuppression and HPV-associated disease, treatment with highly active antiretroviral therapy (HAART) has the potential, through immune reconstitution of the host, to alter the natural history of HPV infection and SIL. However, data on the impact of HAART on HPV disease are sparse and mixed results have been reported.

Abstract
PURPOSE OF REVIEW Human papillomavirus (HPV) has been strongly implicated in the pathogenesis of cervical intraepithelial neoplasia (CIN) and cervical cancer. Women who are positive for the human immunodeficiency virus (HIV) have been shown to be at increased risk for cervicovaginal HPV infection and CIN, and cervical cancer is an acquired immunodeficiency syndrome-defining illness. The purpose of this review is to summarize recent studies of cervical HPV infection and CIN in HIV-positive women and to describe the effect of highly active antiretroviral therapy (HAART) on the course of CIN. RELEVANT FINDINGS HIV-positive women have a higher prevalence of cervical HPV infection than HIV-negative women, and HPV infection is more persistent in the HIV-positive population. The incidence of high-grade CIN is increased in HIV-positive women. HAART has not been shown to affect HPV detection, and data on its effect on the natural history of CIN are mixed. Some studies show no effect of HAART on the natural history of CIN, and others show a statistically significant but modest beneficial effect. SUMMARY Cervical HPV infection and CIN are clearly increased in HIV-positive women when compared with risk-matched HIV-negative women. HAART appears to have limited ability to clear HPV infection and induce regression of CIN in HIV-positive women. Combined with the high prevalence of cervical HPV infection and CIN, current data suggest that CIN should be aggressively sought and treated in HIV-positive women, including those who have responded well to HAART with good HIV viral load suppression and increasing CD4+ levels.

Abstract
Much has been learned about HIV disease during its first 20 years of existence in North America. The virus can now be successfully suppressed by HAART therapy, yet complete viral eradication from the body has not been demonstrated, and HIV transmissions continue to occur at an alarming rate. With support of the immune system, many HIV-infected patients will avoid oral and systemic opportunistic illnesses (or at least significantly prolong their time to onset). The number of HIV-infected patients under dental care is expected to increase in the future. Thus, dentists are fortunate that oral health care can be provided safely in the community setting for all but the very sickest of AIDS patients.

Abstract
The prevalence of cellular immunodeficiency has increased due to rising use of immunosuppressive therapies and the pandemic spread of HIV infection. More recently, the introduction of highly active antiretroviral therapy (HAART) in HIV has led to significant immune reconstitution, even in patients with previously long-lasting secondary immunodeficiency. HAART reduces morbidity and mortality in HIV infection and also changes the clinical course of prevalent subclinical opportunistic infections or autoimmune diseases. Atypical inflammatory disorders develop after initiation of HAART and have been summarized as "immune reconstitution syndrome," "immune restoration disease," and "immune restoration inflammatory syndrome." However, diagnostic criteria and standards of therapy are yet to be defined. The awareness for these diseases is of increasing importance from a clinical point of view. This review summarizes the variety of immunoreconstitution disorders and describes possible diagnostic pitfalls. We also propose possible therapeutic options.

Abstract
In developing countries, the variations in the clinical spectrum of human immunodeficiency virus (HIV)-related oral lesions over time, and the possible effects of antiretroviral therapy, have not been described. In this study we evaluate the clinical spectrum of oral lesions in a series of HIV-infected patients when first examined at the acquired immunodeficiency syndrome (AIDS) clinic of a tertiary care institution in Mexico City, Mexico, and the changes observed over 12 years. All HIV-infected adult patients had an oral examination performed by specialists in oral pathology and medicine who used established clinical diagnostic criteria for oral lesions. Four periods were defined according to the evolving pattern of antiretroviral use: the first 2 were before the introduction of highly active antiretroviral therapy (HAART) and the last 2 were during more established use of HAART. For the statistical analysis the chi-square test for contingency tables and the chi-square test for trend were utilized. For dimensional variables, except age, the Kruskal-Wallis or Mann-Whitney rank sum tests were used when applicable and trend was tested with the Spearman correlation coefficient. Age was tested through analysis of variance (ANOVA) and linear regression analysis. Alpha value was set at p = 0.05 for each test. In the 12-year study, 1,000 HIV-infected patients were included (87.9% male). At the baseline examination, oral lesions strongly associated with HIV were present in 47.1% of HIV-infected patients. Oral candidosis (31.6%), hairy leukoplakia (22.6%), erythematous candidosis (21.0%), and pseudomembranous candidosis (15.8%) were the most frequent lesions. Oral Kaposi sarcoma (2.3%), HIV-associated periodontal disease (1.7%), and oral non-Hodgkin lymphoma (0.1%) were less frequent. HIV-related oral lesions decreased systematically-by half during the course of the 4 study periods (p < 0.001). Except for Kaposi sarcoma, all oral lesions strongly associated with HIV showed a trend to decrease significantly during the study period. No apparent variation in the occurrence of salivary gland disease or human papillomavirus-associated oral lesions was found. A significant trend to a lower prevalence was observed in the group of patients who were already taking antiretroviral therapy, non-HAART and HAART (p < 0.001 and p = 0.004, respectively). Only a discrete reduction, barely significant, was noted among untreated patients (p = 0.060). By Period IV (1999-2001), those who received HAART showed the lowest prevalence of oral lesions strongly associated with HIV (p < 0.001). Patients with oral lesions strongly associated with HIV had significantly lower median CD4+ counts and higher viral loads than those without oral lesions strongly associated with HIV (p < 0.001 and p = 0.005, respectively). When CD4+ counts were correlated with prevalence of oral candidosis, a consistently negative association was found; this association prevailed even after the study group was partitioned according to period. In this selected cohort of 1,000 patients with HIV infection, the clinical spectrum of HIV-related oral lesions has changed over the 12-year study, with a decreased prevalence of most oral lesions. Our findings probably represent improvements in medical care of HIV-infected persons, earlier detection of HIV-infected patients at the AIDS clinic, the increasing use of prophylactic drugs to prevent secondary AIDS-related opportunistic infections, and, perhaps most important, the availability of potent antiretroviral therapy in recent years, since the introduction of HAART.

Abstract
OBJECTIVE Oral warts arising in human immunodeficiency virus (HIV) infection occasionally show marked epithelial dysplasia. However, anecdotal evidence suggests that they do not progress to oral squamous cell carcinoma (SCC). Therefore, we evaluated lesions for expression of proteins (tenascin-C, beta6 integrin, and matrix metalloproteinase-1[MMP1]) that have been identified as important in the invasive phase of oral SCC. STUDY DESIGN Twenty-two oral dysplastic warts from 22 patients and 5 oral SCCs were stained for human papillomavirus (HPV) antigen, proliferation protein Ki-67, tenascin-C, beta6, and MMP1 by immunohistochemical methods. For comparison, 5 nondysplastic warts each from HIV-positive and HIV-negative patients and 5 normal mucosa specimens were included. Sections were semiquantitatively assessed, and results were compared. Because MMP1 was the lowest or least expressed interface protein, MMP1 mRNA was quantitatively assessed from formalin-fixed paraffin-embedded tissue in selected cases with quantitative reverse transcription-polymerase chain reaction. RESULTS Twenty of 22 dysplastic warts stained positive for human papillomavirus common antigen, and all warts showed high proliferative fractions similar to SCCs. Tenascin-C and beta6 were variably expressed by the dysplastic warts but were consistently expressed at high levels in the SCCs. MMP1 protein levels were negative or low in 20 of 22 in dysplastic warts, but were elevated in 4 of 5 SCCs. MMP1 mRNA analysis indicated that message was low in 4 dysplastic warts and also suggested that protein translation was incomplete in 3 of the warts. CONCLUSION We conclude that invasion-associated proteins are underexpressed in oral dysplastic warts in HIV-positive men. However, until these patients are followed for extended periods, the risk of development of SCC from oral dysplastic warts remains unknown.

Abstract
In this study we developed a highly reproducible intracranial murine model of cryptococcosis. Mice (Balb/c, 5-7 weeks old) were challenged intracranially and treated with intermediate (30 mg/kg) or high (90 mg/kg) dose fluconazole, and amphotericin B (0.75 mg/kg), administered singly or in combination with flucytosine (100 mg/kg). Survival and brain CFU analyses were performed. Effect of fluconazole prophylaxis was also determined. Our data show that the developed model mimics clinical signs of cryptococcal meningitis. In single treatment, fluconazole (30 mg/kg) was more efficacious than amphotericin B or flucytosine (P < 0.0001). Combination treatment led to significantly increased anticryptococcal activity, which was highest for high dose fluconazole + flucytosine (P < 0.0001). However, no significant difference was observed between high dose fluconazole treatment with and without flucytosine (P >0.05). Fluconazole prophylaxis led to a significant decrease in brain CFU. In conclusion, high dose fluconazole administered post-infection, or as prophylaxis, may be highly efficacious in the treatment and prevention of meningoencephalitis.

Abstract
The HIV family replicate in and are shed from the mouth. Oral sexual practices potentially contribute to the overall extent of HIV transmission, particularly if high-risk practices are not restricted. Herpesviruses and papillomaviruses that appear in the oral cavity can determine oral HIV replication. The mechanisms probably include heterologous transactivation, enhanced expression of HIV receptors and co-receptors in target cells, release of cytokines and chemokines, and production of superantigens. Oral diseases peculiar to, or more common in, the HIV-infected patient further predispose to heightened oral HIV replication and trafficking. Defining the mechanisms by which oral viruses interact with HIV in the co-infected host should permit intervention measures against oral HIV transmission to be more precisely targeted.
