Abavisani M, Keikha M. Global analysis on the mutations associated with multidrug-resistant urogenital mycoplasmas and ureaplasmas infection: a systematic review and meta-analysis. Ann Clin Microbiol Antimicrob 2023; 22:70. [PMID: 37563660 PMCID: PMC10416482 DOI: 10.1186/s12941-023-00627-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/04/2023] [Accepted: 08/03/2023] [Indexed: 08/12/2023] Open
Abstract
BACKGROUND The emergence of multidrug-resistant (MDR) strains of genital pathogens, notably Mycoplasma genitalium and Ureaplasma spp., constitutes a significant global threat today. The present study aimed to evaluate the prevalence and trend of changes in MDR mycoplasma and ureaplasma strains. METHODS An exhaustive search was performed across the ISI Web of Science, PubMed, Scopus, ScienceDirect, and Google Scholar databases to accumulate relevant studies without restrictions until April 2023. We used event rate and corresponding 95% confidence intervals to determine the frequency of resistance-related mutations and examine the trend of antibiotic resistance changes. RESULTS The data from 27 studies, including 24,662 patients across 14 countries, were evaluated. Out of the total studies, 20 focused on M. genitalium infections, and five on Ureaplasma spp. The frequency of resistance-associated mutations to macrolides, tetracyclines, and fluoroquinolones in clinical strains of M. genitalium was 43.5%, 13.1%, and 18.6%, respectively. The prevalence of M. genitalium strains with double resistance and MDR was 11.0% and 17.4%, respectively. The incidence of both double-drug-resistant and MDR strains was higher in the World Health Organization (WHO) Western Pacific Region than in European and American populations. For Ureaplasma strains, resistance-associated mutations to macrolides, tetracyclines, and fluoroquinolones were 40.8%, 25.7%, and 90.3%, respectively. The rate of antibiotic resistance was higher in the African population compared to the European and WHO Western Pacific Regions. The rate of MDR Ureaplasma infections was 13.2%, with a higher incidence in the African population compared to the WHO Western Pacific and European regions. CONCLUSION The proliferation and spread of MDR Mycoplasma and Ureaplasma strains present a significant public health challenge. The situation is indeed alarming, and the rising trend of MDR M. genitalium and MDR Ureaplasma infections suggests that therapies involving macrolides and fluoroquinolones may become less effective.

Abstract
Mycoplasma salivarium, an oral commensal organism, can cause severe invasive infections in immunocompromised individuals. Currently there is no treatment guidance for such infections. We performed antimicrobial susceptibility tests on 39 commensal and invasive M. salivarium isolates and investigated the mechanisms of antimicrobial resistance. Clindamycin was the most active agent [minimum inhibition concentration (MIC) range: 0.004–128 mg/L, MIC50 = 0.031 mg/L, MIC90 = 0.125 mg/ml], followed by tetracycline and levofloxacin. All isolates were resistant to erythromycin (MIC ≥4 mg/L) due to the presence of 2057A (Escherichia coli numbering) in 23S rRNA. Three isolates with elevated clindamycin MICs (≥8 mg/L) harbored A2058T/G mutations in 23S rRNA gene; four sequential isolates from one patient developed C2611T and A2059G mutations accompanying the increase of clindamycin MICs. Five isolates with elevated tetracycline MICs (≥4 mg/L) had mutations in 16S rRNA gene (A965G/T, G966T, or A967C/T) and one of them harbored TetM. Nine isolates with elevated levofloxacin MICs (≥4 mg/L) had one or more mutations in gyrA, gyrB, parC, or parE. Susceptibility breakpoints for clindamycin, tetracycline and levofloxacin were suggested to be ≤0.125, ≤2, and ≤2 mg/L, respectively. Antimicrobial resistance to any of the three agents (clindamycin, tetracycline, or levofloxacin) was documented in 12 (34.3%) non-duplicate isolates, of which 10 were invasive. Levofloxacin resistance was most frequent (25.7%). Multi-drug resistance was also observed (14.3%). This study demonstrates the frequent occurrence of antimicrobial resistance in M. salivarium, emphasizing the need for culture and susceptibility testing to guide antimicrobial therapy.

Abstract
Gingival enlargement may be a result of multifactorial etiology which includes local factors such as calculus, food lodgement, overhanging restorations, and overextended dentures as well as systemic conditions such as hormonal disturbances and blood dyscrasias. Acquired immune deficiency is a manifestation of immune disorder caused by a retrovirus Human Immunodeficiency Virus (HIV). The association of Acquired Immunodeficiency Syndrome or HIV with oral and periodontal lesions is highly significant. Seropositive patients usually present with periodontal diseases and atypical periodontal lesions. These clinical findings may prove to be a link for probing patients' systemic health. This case report describes one such case of a patient, unaware of HIV infection with localized gingival overgrowth, wherein detailed probing and investigation led to the diagnosis of underlying systemic condition as acquired immunodeficiency. Subsequently, antiretroviral therapy was started, and nonsurgical periodontal therapy was performed to resolve the gingival overgrowth.

Abstract
With the advent of combined antiretroviral therapies, the face of HIV infection has changed dramatically from a disease with almost certain mortality from serious comorbidities, to a manageable chronic condition with an extended lifespan. In this paper we present the more recent investigations into the epidemiology, microbiology, and pathogenesis of periodontal diseases in patients with HIV, and the effects of combined antiretroviral therapies on the incidence and progression of these diseases both in adults and perinatally infected children. In addition, comparisons and potential interactions between the HIV-associated microbiome, host responses, and pathogenesis in the oral cavity with the gastrointestinal tract and other areas of the body are presented. Also, the effects of HIV and combined antiretroviral therapies on comorbidities such as hyposalivation, dementia, and osteoporosis on periodontal disease progression are discussed.

Abstract
BACKGROUND The effects of methamphetamine (MA) on caries have been well documented. Little, however, is known about its effects on the periodontium. The authors conducted this study to determine the prevalence and severity of periodontal disease in an urban population of HIV-positive MA users. METHODS This cross-sectional survey was conducted in one of the most populous urban areas of Los Angeles County, California, beset with high rates of MA use. Participants were recruited by a combination of street outreach methods, referral from drug treatment centers, and word of mouth. Participants were eligible if they were older than 18 years, spoke English or Spanish, used MA in the past 30 days, were willing to undergo a dental examination and psychosocial assessments, and were willing to provide a urine sample. Periodontal assessments were completed for 541 participants by 3 trained and calibrated dentists. RESULTS The prevalence and severity of periodontal disease were high in this population of HIV-positive and -negative MA users. Cigarette smoking and age were identified as risk factors. CONCLUSIONS The HIV-positive and -negative cohorts were remarkably similar, suggesting that their lifestyles contributed more to their destructive periodontal disease than their MA use. PRACTICAL IMPLICATIONS MA users are at high risk of developing destructive periodontal disease and badly broken-down teeth. Clinicians should plan accordingly for timely management of the patients' care, knowing that MA users have extensive periodontal and restorative treatment needs.

Abstract
We herein report the case of a 41-year-old Japanese man with well-controlled HIV who presented with diagnostically difficult acute necrotizing ulcerative gingivitis (ANUG). After diet-induced weight loss, he developed oral pain and disturbance of mouth opening, and was admitted to our hospital. Based on preconceptions of HIV-associated diseases, fluconazole was initiated for candidiasis. However, no improvement was seen and ANUG was finally diagnosed. This case suggests that physicians should consider ANUG in HIV-infected individuals when several risk factors are present, even if CD4+ T-lymphocyte counts have remained stable owing to long-term anti-retroviral therapy.

Abstract
The workshop addressed the following questions with respect to periodontal diseases and bacterial infections seen in HIV infection: (1) What is linear gingival erythema? Is it prevalent only in HIV disease? A crude Delphi technique was used to ascertain whether LGE existed, but a consensus could not be reached. It was agreed that a diagnosis of LGE should be considered only if the lesion persists after removal of plaque in the initial visit. (2) Do periodontal pockets contribute to viremia in HIV infection? At present, the data are not available to answer this question. (3) Do anti-viral drugs reach the sulcular fluid in significant concentrations? No one at the workshop was aware of data that could answer this question. (4) Does concurrent tuberculosis infection modify the oral manifestations of HIV infection? Though analysis of data from the developing countries does suggest an association between tuberculosis and oral candidiasis, more data and multivariate analysis considering immunosuppression as a confounding factor are necessary, for any conclusions to be derived. (5) What pathogens are involved in periodontal diseases in HIV infection? Periodontal disease may be initiated by conventional periodontal pathogens. But the progression and tissue destruction depend upon the presence of typical and atypical micro-organisms, including viruses, their by-products, increased secretion of potentially destructive inflammatory mediators, and overwhelming host response. (6) How can we diagnose the diseases seen in HIV infection? The answer can be obtained only with data from controlled and blinded studies. It is necessary to design collaborative multi-center longitudinal studies. The results obtained from such large sample sizes can contribute eventually to interpretation of the outcome.

Abstract
Introduction: Acquired Immuno Deficiency Syndrome (AIDS) is a condition in which the body becomes susceptible to a host of opportunistic infections. This syndrome is a culmination of infection with a lenti virus called Human Immunodeficiency Virus (HIV) particularly HIV 1. A cross section of the population including adults and children are affected by HIV infection with estimate of 36.1 million affected by the end of 2014. HIV infection affects the T lymphocytes especially cluster of differentiation 4 (CD4) count reducing it drastically jeopardizing the acquired immunity. The advent of Anti Retroviral Therapy (ART) has proved as a ray of hope, at least reducing the misery and suffering although not permanently. This study attempts to understand the prevalence of periodontal disease and other oral lesions, further examining their relationship with CD4 counts in the HIV seropositive patients on ART. Materials and Methods: A total of 72 HIV positive patients on ART reporting at ART centre at Raichur District hospital were screened in the study for periodontal status, oral manifestations. The latest CD4 count values were obtained from the hospital records. Results: The study showed a 36.11% of prevalence of periodontal disease; however no statistically significant association was seen with its relation to CD4 counts. Other oral manifestations were seen in 46% of patients with a high prevalence of Oral Candidiasis lesions and a positive association with CD 4 counts was seen. Conclusion: Under the limitations of this study no significant association was seen between CD4 counts and prevalence of periodontal disease however candiasis showed a stronger association. As HIV infection gradually becomes a chronic disease the features and course of chronic periodontal disease and other oral manifestations in HIV infected patients require more careful and extensive investigation.

Abstract
The introduction of highly active antiretroviral therapy (HAART) has decreased the incidence and prevalence of several oral manifestations such as oral candidiasis, hairy leukoplakia, and Kaposi's sarcoma in HIV-infected patients. Regarding periodontal disease the findings are not clear. This disease represents a group of chronic oral diseases characterized by infection and inflammation of the periodontal tissues. These tissues surround the teeth and provide periodontal protection (the gingival tissue) and periodontal support (periodontal ligament, root cementum, alveolar bone). Clinical, immunological, and microbiological aspects of these diseases, such as linear gingival erythema (LGE), necrotizing periodontal diseases (NPD) (necrotizing ulcerative gingivitis [NUG], necrotizing ulcerative periodontitis [NUP] and necrotizing stomatitis), and chronic periodontitis, have been widely studied in HIV-infected individuals, but without providing conclusive results. The purpose of this review was to contribute to a better overall understanding of the probable impact of HIV-infection on the characteristics of periodontal infections.

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
The effect of HIV infection on the prevalence and the rate of progression of chronic periodontitis is not clear. The aim of this study was to compare parameters associated with the severity of chronic periodontitis in terms of periodontal probing depths, gingival recession, plaque indexes, and bleeding indexes of HIV-seropositive subjects and healthy age-matched control subjects, and of HIV-seropositive subjects on highly active antiretroviral therapy and those not receiving such treatment. Two cohorts of subjects with chronic periodontitis were recruited for this study over a period of six months. There were 30 HIV-seropositive subjects, and 30 control subjects. Periodontal probing depths, gingival marginal recession, plaque indexes, and bleeding indexes were compared by HIV serostatus, the use of highly active antiretroviral therapy, and CD4+ T-cell counts. All participants were black persons between the age of 18 and 45 and were of a similar socioeconomic status and age. The results of this study indicate that chronic periodontitis in HIV-seropositive subjects is similar in terms of mean periodontal probing depth, gingival marginal recession, plaque index, and bleeding index to that in healthy age-matched control subjects, and a low CD4+ T-cell count does not appear to be a risk factor for increased severity of chronic periodontitis.

Abstract
Primary infection of oral epithelial cells by HIV-1, if it occurs, could promote systemic infection. Most primary systemic infections are associated with R5-type HIV-1 targeting the R5-specific coreceptor CCR5, which is not usually expressed on oral keratinocytes. Because coinfection with other microbes has been suggested to modulate cellular infection by HIV-1, we hypothesized that oral keratinocytes may up-regulate CCR5 in response to the oral endogenous pathogen Porphyromonas gingivalis by cysteine-protease (gingipains) activation of the protease-activated receptors (PARs) or LPS signaling through the TLRs. The OKF6/TERT-2-immortalized normal human oral keratinocyte line expressed CXCR4, whereas CCR5 was not detectable. When exposed to P. gingivalis ATCC 33277, TERT-2 cells induced greater time-dependent expression of CCR5-specific mRNA and surface coreceptors than CXCR4. By comparing arg- (Rgp) and lys-gingipain (Kgp) mutants, a mutant deficient in both proteases, and the action of trypsin, P. gingivalis Rgp was strongly suggested to cleave PAR-1 and PAR-2 to up-regulate CCR5. CCR5 was also slightly up-regulated by an isogenic gingipain-deficient mutant, suggesting the presence of a nongingipain-mediated mechanism. Purified P. gingivalis LPS also up-regulated CCR5. Blocking TLR2 and TLR4 receptors with Abs attenuated induction of CCR5, suggesting LPS signaling through TLRs. P. gingivalis, therefore, selectively up-regulated CCR5 by two independent signaling pathways, Rgp acting on PAR-1 and PAR-2, and LPS on TLR2 and TLR4. By inducing CCR5 expression, P. gingivalis coinfection could promote selective R5-type HIV-1 infection of oral keratinocytes.

Abstract
Gingival crevicular fluid (GCF), a serum transudate or inflammatory exudate, can be collected from the gingival crevice surrounding the teeth. As such, the fluid reflects the constituents of serum, the cellular response in the periodontium, and contributions from the gingival crevice. The study of GCF has focused on defining the pathophysiology of periodontal disease, and identification of a potential diagnostic test for active periodontitis. The majority of markers that have been identified as potential candidates for such a test are measures of inflammation (i.e., prostaglandin E2 (PGE2), neutrophil elastase, and the lysosomal enzyme beta-glucuronidase). Further, analysis of inflammatory markers in GCF may assist in defining how certain systemic disorders (e.g., diabetes mellitus) can modify periodontal disease, and how periodontal disease/periodontal inflammation can influence certain systemic disorders (i.e., cardiovascular/cerebrovascular diseases). Methodological concerns related to the collection and analysis of GCF are important factors that need to be considered when studying GCF. Practical concerns argue against the widespread clinical application of GCF as an adjunct to periodontal diagnosis. Rather, analysis of GCF-derived mediators in saliva may serve as a means of rapid screening for periodontal disease.

Abstract
AIM To describe and compare the predominant bacterial and fungal species associated with gingivitis, periodontitis, and linear gingival erythema (LGE), in HIV positive subjects with different immune status. METHODS Viral loads and CD4 levels determined HIV disease status. From pooled subgingival plaque, 16S and 18S rDNA were cloned and sequenced to determine species identity. RESULTS One hundred and nine bacterial species were identified from 14 subjects. Nearly half of the species were not cultivable. Notably, the classical putative periodontal pathogens, Treponema denticola, Porphyromonas gingivalis and Tannerella forsythia were below the limit of detection and were not detected. Species of Gemella, Dialister, Streptococcus and Veillonella were predominant. In one HIV positive subject with periodontitis and low viral load, Gemella morbillorum, a known opportunistic pathogen, constituted 84% of the clones. Saccharomyces cerevisiae was the only fungal species detected in an LGE subject and in periodontitis subjects with high viral loads. In periodontitis patients with low viral loads, Candida albicans was predominant, while S. cerevisiae was only a minor component. CONCLUSION These case studies suggest that other bacterial species, rather than the classical periodontal pathogens, may be involved in periodontal diseases of subjects with HIV. These data are indicative of opportunistic infections in a highly susceptible immunocompromised host.

Abstract
AIMS To review the literature related to the analytical epidemiology of periodontitis generated over the past decade. This review does not deal with descriptive epidemiologic studies of the prevalence, extent and severity of periodontitis with respect to global geography, but focuses exclusively on analytical epidemiology issues, including the challenges posed by the use of different case definitions across studies, current theories and models of disease progression, and risk factors associated with the onset and progression of periodontitis. METHODS Relevant publications in the English language were identified after Medline and PubMed database searches. FINDINGS AND CONCLUSIONS There is a conspicuous lack of uniformity in the definition of periodontitis used in epidemiologic studies, and findings from different research groups are not readily interpretable. There is a lack of studies that specifically address the distinction between factors responsible for the onset of periodontitis versus those affecting its progression. Colonization by specific bacteria at high levels, smoking, and poorly controlled diabetes have been established as risk factors for periodontitis, while a number of putative factors, including specific gene polymorphisms, have been identified in association studies. There is a clear need for longitudinal prospective studies that address hypotheses emerging from the cross-sectional data and include established risk factors as covariates along with new exposures of interest. Intervention studies, fulfilling the "targeting" step of the risk assessment process, are particularly warranted. Obvious candidates in this context are studies of the efficacy of elimination of specific bacterial species and of smoking cessation interventions as an alternative to the traditional broad anti-plaque approach in the prevention and control of periodontitis. Ideally, such studies should have a randomized-controlled trial design.

Abstract
The purpose of this review was to evaluate the evidence supporting the hypothesis that viral infection plays a role in the development of periodontitis. An involvement in periodontal diseases has been suspected specifically for human immunodeficiency virus (HIV) and herpes viruses. An association has been demonstrated between HIV infection and some distinct forms of periodontal infection, i.e. necrotizing lesions. Furthermore, reports of increased prevalence and severity of chronic periodontitis in HIV-positive subjects suggests that HIV infection predispose to chronic periodontitis. Several studies, most of them from the same research group, have demonstrated an association of herpesviruses with periodontal disease. Viral DNA have been detected in gingival tissue, gingival cervicular fluid (GCF) and subgingival plaque from periodontaly diseased sites. In addition markers of herpesviral activation have been demonstrated in the GCF from periodontal lesions. Active human cytomegalovirus (HCMV) replication in periodontal sites may suggest that HCMV re-activation triggers periodontal disease activity. Concerns regarding sampling, methods and interpretation cast doubts on the role of viruses as causes of periodontal disease.

Abstract
BACKGROUND Necrotizing ulcerative periodontitis (NUP) is a painful and potentially debilitating affliction that affects about 2% to 6% of HIV-positive subjects. NUP may be caused by specific microorganisms that are presently unknown or by microbial species not usually thought to cause periodontal infections. The purpose of this study was to define the bacterial species associated with NUP in HIV-positive patients. METHODS 16S rRNA bacterial genes of DNA isolated from subgingival plaque of 8 HIV-positive subjects with NUP were amplified by polymerase chain reaction (PCR) and cloned into Escherichia coli. The sequences of cloned inserts were used to determine species identity or closest relatives by comparison with known sequences. The microbial profiles in subgingival plaque of subjects with NUP, chronic periodontitis, and periodontal health were compared using a battery of over 200 oligonucleotide probes in a PCR-based, reverse-capture, checkerboard DNA-DNA hybridization assay. RESULTS Sequence analysis of over 400 clones revealed 108 species; 65 were "uncultivable" phylotypes, of which 26 were novel to NUP subjects. Species or phylotypes most commonly detected were Bulleidia extructa, Dialister, Fusobacterium, Selenomonas, Peptostreptococcus, Veillonella, and the phylum TM7. Based on sequence analysis and checkerboard analysis, NUP did not possess the classical periodontal pathogens such as Porphyromonas gingivalis. Otherwise, the microbial profiles of NUP and periodontitis had many similarities. The microbial profiles of subgingival plaque from periodontally healthy subjects were different and less complex in comparison to the profiles of both disease groups. CONCLUSIONS Certain species appear to be associated with health and periodontal diseases. The putative pathogens associated with periodontal disease in HIV-negative subjects are not associated with NUP in HIV-positive subjects.

Abstract
BACKGROUND Mast cells are a prominent cell type in the gingival infiltrate in periodontitis. In this study we examined the expression by gingival mast cells of matrix metalloproteinases, MMP-1, MMP-2, MMP-8 and the tissue inhibitors of metalloproteinases, TIMP-1 and TIMP-2. METHODS Gingival specimens from 12 human immunodeficiency virus-negative (HIV-) and 15 HIV-positive (HIV+) patients with chronic marginal periodontitis (CMP), and from 10 HIV- and four HIV+ controls with clinically healthy gingiva (HG) were examined after double immunofluorescence staining for mast cell tryptase, combined with antibodies for MMP-1, MMP-2, MMP-8 or their inhibitors TIMP-1 and TIMP-2. RESULTS In the HIV+CMP, HIV+HG and HIV-CMP groups, all mast cells expressed MMP-1 and MMP-8, whereas a smaller proportion (40-60%) in the HIV-HG controls displayed such staining. The former groups also displayed a significantly higher proportion (39-64%) of mast cells expressing MMP-2 as compared with the HIV-HG group (21-31%). All groups displayed similar proportions of TIMP-1 expressing mast cells (86-100%), whereas significantly increased proportions of TIMP-2+ mast cells were seen in the HIV+CMP, HIV+HG and HIV-CMP groups (18-25%) as compared with the HIV-HG group (8-13%). Mast cells were the cell type that most prominently expressed MMP-1 and MMP-8. MMP-2 expression was also strong in mast cells, but was also similarly expressed in other cell types. CONCLUSION The chronically inflamed periodontal lesions in the present study appeared with little evidence of mast cell degranulation. The results show, however, that mast cells in inflamed gingiva have the potential to degrade extracellular matrix if appropriately triggered.

Abstract
Oral manifestations of HIV infection are sometimes the first sign of the disease and often indicate its progression to acquired immune deficiency syndrome (AIDS), thus it is important for health professionals (physicians and dentist) to possess adequate knowledge of these lesions. Improvements in antiretroviral treatments, especially with the incorporation of HAART therapy, have produced a gradual reduction in the prevalence of HIV-associated oral lesions. On the other hand, the increased life expectancy of HIV-positive patients has led to their greater presence at our clinics, implying the need for continuous updating in the diagnosis and treatment of these processes. Using the consensus classification (EEC-Clearinghouse, 1993) we reviewed the diagnostic criteria and current treatment protocols for the different HIV infection related oral lesions in both adults and children.

Abstract
During the past decade, a large number of new drugs for treating HIV and its complications have been developed. The increasingly sophisticated use of these drugs in combination has led to a marked reduction in HIV-related morbidity and mortality in countries where they are available. HIV/AIDS patients receiving treatment are now expected to live into old age. The beneficial effect of HIV treatment has resulted in an expanding population of persons living with HIV/AIDS who will need the care of an HIV specialist because of the complexity of the treatment regimens and the rapidly changing HIV/AIDS knowledge base. However, this growing and aging population will also benefit from the care of a primary care physician. The primary care generalist is in the best position to recognize and diagnose HIV infection, evaluate HIV risk in his or her patient population, and help prevent HIV infection in persons at risk. In patients known to be infected, the primary care generalist will be best able to manage hyperlipidemia, diabetes, cardiovascular disease, and other disorders of an aging population with an increased risk of these and other conditions. Patients with HIV infection frequently accumulate a large number of specialist physicians, and the unique ability of the primary care physician to monitor their care and act as a knowledgeable patient advocate is a great benefit to the patient.

Abstract
With the advent of newer pharmacological approaches to the treatment of human immunodeficiency virus (HIV) infection, the incidence and progression of both atypical and conventional periodontal diseases are changing. The incidence of necrotizing periodontitis and gingival diseases of fungal origin appears to be on the decline as a result of these therapies that have led to increased life spans for HIV patients. However, in cases where these therapies lose their effectiveness and HIV patients relapse into an immunosuppressed state, these conditions may recur. Recent evidence has shown that HIV patients with more conventional periodontal diseases such as chronic periodontitis may have increased attachment loss and gingival recession when compared to their HIV-negative counterparts. This pattern of loss of periodontal support may be due in part to a diffuse invasion of opportunistic bacterial infections, viruses, and fungi into the gingival tissue, leading to a more elevated and more diffuse destructive inflammatory response in the periodontal soft and hard tissues. While the accepted approaches to treating the spectrum of periodontal diseases in HIV patients remain essentially unchanged over the past 15 years, the impact of newer systemic therapies on patient immunocompetence may influence treatment decisions.

Abstract
BACKGROUND The author describes the use of lasers to palliate the oral manifestations of the human immunodeficiency virus, or HIV, infection. He discusses the advantages to both patients and dentists, but he does not address the use of lasers as a modality to treat or cure HIV infection. CASE DESCRIPTION Many oral manifestations of HIV infection can be used as markers for degree of immunosuppression. These manifestations may be treated with antibiotics, analgesics and antineoplastics, which may interact and interfere with antiviral agents used to treat the disease and possibly may exacerbate it. The author describes laser palliation of the oral manifestations of three HIV-positive patients. CLINICAL IMPLICATIONS Dentists will see more patients living longer with HIV as the disease becomes more treatable. Lasers have been shown to be effective instruments in palliation of oral manifestations of HIV infection.

Abstract
BACKGROUND HIV infection increases susceptibility for marginal periodontitis, with horizontal and rapid loss of periodontal soft tissues and alveolar bone. OBJECTIVES To examine whether numbers, distribution and some properties of mast cells, neutrophils and macrophages are normal in chronically inflamed gingiva of HIV-positive patients. METHODS Gingival biopsies were stained for mast cell tryptase and chymase, neutrophil elastase, CD68, human transforming growth factor beta(1), HLA-DR, Fc gamma RI, Fc gamma RII and Fc gamma RIII and calprotectin. RESULTS Patients at all stages of HIV infection showed radically increased numbers of mast cells and neutrophils throughout the connective tissue, and of macrophages below the oral gingival epithelium (P < 0.05). CONCLUSION HIV infection is associated with increased numbers of mast cells, macrophages and neutrophils in the chronic periodontal lesion. This may predispose for tissue destruction through the release of inflammatory mediators and effector molecules. The unusually heavy cell infiltrate throughout the gingival connective tissue may contribute to the diverging pattern of periodontal tissue loss in HIV-positive patients.

Abstract
BACKGROUND Manifestations of immunosuppression may take the form of opportunistic infection, and neoplasia. While this paper has focused on gingival and periodontal manifestations. these tissues cannot be evaluated in isolation. The presence of involvement of other oral tissues such as the cheek or tongue with manifestations associated with HIV such as hairy leukoplakia, Kaposi's sarcoma at these sites, and candidiasis in addition to periodontal manifestations may further increase the clincal suspicion of underlying immunosuppression and/or progression of the immunosuppressive state. DISCUSSION The periodontist plays an essential r le in identifying the periodontal status of an individual and has an important r le to play in early recognition of signs and symptoms of HIV disease or progression of the medical condition. CONCLUSION Only through such recognition can appropriate definitive diagnostic testing be conducted, and appropriate therapeutic intervention for the oral condition and the systemic condition be considered.

Abstract
The oral cavity is rarely reported to be a site of human immunodeficiency virus (HIV) transmission, despite detectable virus in saliva and relatively frequent prevalence of periodontal disease in HIV-infected persons yielding increased excretion of mononuclear-cell-enriched gingival fluid. To search for possible sources of HIV in saliva, and using the polymerase chain-reaction technique, we sought the presence and shedding patterns of proviral HIV-1 DNA in gingival crevicular fluid in a group of patients previously determined as HIV-1-seropositive. Periodontal status at the collection sites was monitored by several clinical parameters, including Plaque Index, Gingival Index, probing depth, and clinical attachment loss. Gingival crevicular fluid samples were collected by means of paper points. Proviral HIV-1 DNA was detected in the gingival fluid of 17 out of 35 HIV-1-infected patients. Its detection correlated significantly with higher plasma HIV-1 RNA viral load (p = 0.03) and not with peripheral blood CD4+ cell count, the presence of blood in gingival fluid, or oral lesions. There was a significant correlation between clinical attachment loss at the sites of fluid collection and plasma HIV-1 RNA viral load (p = 0.002), and borderline correlation between the latter and probing depth (p = 0.54) in the group of patients harboring proviral HIV-1 DNA in gingival crevicular fluid. The results of our study suggest that mononuclear cells present in gingival crevicular fluid and harboring proviral HIV-1 DNA could represent a potential source of HIV-1 in the presence or absence of local bleeding, especially in persons with advanced HIV infection and increased loss of clinical attachment.

Abstract
OBJECTIVES To determine the relationship of immunosuppression with measures of probing pocket depth (PPD), recession (REC), and clinical attachment level (CAL) in an HIV-infected population from North Carolina (NC), a state in the southeastern United States (USA). DESIGN Cross-sectional study of HIV-infected adults (n = 326) treated at the University of North Carolina Hospitals. Clinical medical record review and sociodemographic interview data were collected. Median age of study participants was 37 years (range 19-67). Males comprised 78% and Blacks 60%. Analyses were limited to those who were dentate (n = 316). MAIN OUTCOME MEASURES Main outcomes were cases vs non-cases of notable PPD, REC, and CAL. Immunosuppression measured by CD4+ cell count microL was the exposure of interest. RESULTS Defined cases of PPD (n = 148) were 2.6 (95% CI = 1.3, 5.3) times less likely to occur at CD4+ cells < 200 than non-cases, whereas, cases of REC (n = 94) were 2.8 (95% CI = 1.2, 6.6) times more likely to occur at that level of severe immunosuppression, controlling for confounders. CONCLUSION Sub-groups of persons with HIV experience a high burden of periodontitis where notable severity and extent of PPD, CAL, and REC were clearly evident at different stages of immunosuppression.

Abstract
Oral lesions are important in the clinical spectrum of HIV/AIDS, arousing suspicion of acute seroconversion illness (aphthous ulceration and candidiasis), suggesting HIV infection in the undiagnosed individual (candidiasis, hairy leukoplakia, Kaposi's sarcoma, necrotizing ulcerative gingivitis), indicating clinical disease progression and predicting development of AIDS (candidiasis, hairy leukoplakia), and marking immune suppression in HIV-infected individuals (candidiasis, hairy leukoplakia, necrotizing periodontal disease, Kaposi's sarcoma, long-standing herpes infection, major aphthous ulcers). In addition, oral lesions are included in staging systems for HIV disease progression and as entry criteria or endpoints in clinical trials of antiretroviral drugs. Recognition and management of these oral conditions is important for the health and quality of life of the individual with HIV/AIDS. In keeping with this, the U.S. Department of Health Services Clinical Practice Guideline for Evaluation and Management of Early HIV Infection includes recommendations that an oral examination, emphasizing oral mucosal surfaces, be conducted by the primary care provider at each visit, a dental examination by a dentist should be done at least two times a year, and patients should be informed of the importance of oral care and educated about common HIV-related oral lesions and associated symptoms.

Abstract
Necrotizing periodontal diseases are unique in their clinical presentation and course. Data suggest that the etiology and pathogenesis of necrotizing periodontal diseases may also be distinctive from other periodontal diseases. Necrotizing ulcerative gingivitis (NUG) is a type of necrotizing periodontal disease in which the necrosis is limited to the gingival tissues. Three specific clinical characteristics must be present to diagnose NUG, pain (usually of rapid onset) interdental necrosis, and bleeding. Epidemiological and prospective clinical studies have found an altered ability to cope with psychological stress, immunosuppression, and tobacco use to be strongly associated with the onset of NUG.

Abstract
BACKGROUND Current medical care for patients infected with the human immunodeficiency virus type 1, or HIV-1, involves monitoring laboratory assays for CD4+ lymphocyte cell count and plasma viral load. TYPES OF STUDIES REVIEWED The authors reviewed recent medical and dental studies that contribute to our current understanding of these immunologic and viral markers and their relevance to systemic and oral health. RESULTS Dramatic reduction in plasma viral load resulting from more potent antiretroviral drug combinations is the goal of medical management for HIV. These protease inhibitor-containing regimens, although complex, expensive and associated with substantial side effects, have decreased the morbidity and mortality associated with HIV in the United States. Although reduction in viral load can result in increases in CD4+ counts, which restores some level of immune competence, a cure for AIDS has not yet been found. CLINICAL IMPLICATIONS Patients with low CD4+ cell counts (and often high viral loads) are more likely to develop destructive periodontal infections and other oral manifestations of HIV. Partial recovery of the immune system after viral load reduction may affect both the prognosis and oral disease experience of these patients.

Abstract
Selected periodontopathic bacteria were sought in 20 HIV-infected English patients and eight noninfected control subjects with similar periodontal status, using highly specific DNA probes. Actinobacillus actinomycetemcomitans (A. a), Porphyromonas gingivalis, Campylobacter rectus, Prevotella intermedia, and Fusobacterium nucleatum were more frequently detected and were found at higher levels in HIV-infected individuals than in controls. Significantly increased levels of Treponema denticola but, in contrast, lower levels of Eikenella corrodens were found in nonbleeding sites of HIV-infected patients compared with controls. The results of the present investigation on English patients suggest a periodontopathogenic role for A. a, P. gingivalis and C. rectus, and possibly P. intermedia and are in general accord with most previously reported data from the United States. Longitudinal studies are now required to determine more precisely the association between periodontopathic microflora, immune competence and periodontal health and disease in HIV-infected persons.

Abstract
The aims of this study were to assess types and prevalence of HIV-related oral lesions and to correlate these lesions to the main laboratory parameters such as CD4+ cell count and plasma HIV-RNA. The study population consisted of 104 consecutive HIV+ patients living in Sicily (M=67, 64.4%; F=37, 35.6%; median age=35 years). CD4+ cell count and viral load were measured within 24 h of oral examination. Data were managed and analysed by Epi-Info 6.0. HIV-related oral lesions, as classified by the EC-Clearinghouse, were diagnosed in 35.6% of patients: these were of the Strongly Associated (SA) type in 22.1%, the Less Common Associated (LCA) type in 12.5%, and the Lesions Seen in HIV Infection (LS) type in 3.8%. CD4+ cell counts <200 x 10(6)/l were significantly associated only with SA lesions (P=0.03); median values of CD4+ cell count were also significantly correlated (P=0.02). Viral load, expressed both by median values of copies/ml (P=0.0001) and log10 copies/ml (P=0.0003), was significantly associated only with SA lesions. Treatment failure was significantly correlated to SA lesions (P=0.04). Besides the confirmed correlation with CD4 depletion, the strong association with a high level of viral load could make SA oral lesions a useful tool for identifying progression of HIV infection and could be of value in monitoring antiretroviral therapy.

Abstract
OBJECTIVE Antimicrobial mouthrinses may represent a valid alternative to topical antifungal agents. However, the action of antimicrobials could be affected by the different ingredients incorporated into mouthrinse products. The purpose of the present study was to investigate the in vitro antifungal and fungicidal activities of antimicrobials alone. STUDY DESIGN A broth macrodilution method was used to determine the minimum inhibitory concentration of 4 antimicrobial agents against Candida species. Minimum fungicidal concentration was also determined. RESULTS All antimicrobials showed antifungal activity against all tested organisms, but cetylpyridinium chloride received significantly lower minimum inhibitory concentrations (P < .005). Cetylpyridinium chloride also showed a greater fungicidal activity than chlorhexidine digluconate and hexetidine (P< .005), whereas sanguinarine chloride appeared to be less fungicidal against most of the isolates tested. CONCLUSIONS These findings suggest that cetylpyridinium chloride may be used as a topical antifungal agent. Clinical trials are now required to assess its value in the management of oral candidosis.

Abstract
Periodontal manifestations of human immunodeficiency virus (HIV) infection were first described in 1987. Initially, the lesions receiving attention were HIV-associated gingivitis (now known as linear gingival erythema [LGE]) and HIV-associated periodontitis (now known as necrotizing ulcerative periodontitis [NUP]). The true prevalence of LGE was difficult to determine due to variable diagnostic criteria. Recently, LGE has been associated with intraoral Candida infection. The prevalence of NUP is low (< or = 5%), and this lesion is associated with pronounced immunosuppression. Current focus on the periodontal manifestations of HIV infection centers on rapid progression of chronic adult periodontitis in HIV+ patients. Attempts to identify the pathogenesis of the increased progression of periodontitis have not proven successful. For example, analysis of subgingival plaque for the presence of bacterial pathogens has failed to detect differences between HIV+ and HIV- patients. Recently our laboratory has identified alterations in the host response in the gingival crevice of HIV+ patients. Comparing HIV+ and HIV- injecting drug users (IDU), levels of the proinflammatory cytokine interleukin-1 beta (IL-1 beta) in gingival crevicular fluid (GCF) were slightly elevated at sites with a probing depth of 1 to 3 mm. At deeper sites (> or = 4 mm), total IL-1 beta in GCF was significantly greater in HIV+ individuals. Using the lysosomal acid glycohydrolase beta-glucuronidase (beta G) as a measure of the influx of polymorphonuclear leukocytes (PMN) into the gingival crevice, our data indicated a significant correlation of total beta G in GCF and probing depth in the HIV-IDU (r = 76; P = .02). This result was similar to what we have observed in other studies. In contrast, for HIV+ subjects, total beta G was not associated with probing depth (r = .20; NS). These data suggest that HIV+ patients have altered regulation of PMN recruitment into the gingival crevice. We have begun to investigate the conditions under which subgingival Candida may contribute total periodontal lesions in HIV+ individuals. Candida from subgingival sites has been cultured in HIV+ individuals. Subgingival Candida was distinct from Candida isolated from tongue and buccal mucosal surfaces (as indicated by genomic fingerprinting). We hypothesize the absence of adequate priming of PMN by HIV+ patients. This may be due to a reduced Th1 lymphocyte response. The inability of HIV+ individuals to adequately prime PMN may allow Candida to colonize the subgingival environment. In that milieu, it may act directly or in concert with subgingival bacterial pathogens, or as a cofactor (by inducing production of proinflammatory cytokines) to increase the occurrence of periodontal attachment loss.

Abstract
This report describes a case of rapidly progressive periodontal tissue breakdown and bone loss in an HIV-infected markedly immunosuppressed homosexual male. Within 6 months of initial presentation with a necrotizing ulcerative gingivitis, the lesion extended to a necrotizing ulcerative stomatitis involving the surrounding periodontium and palatal mucosa. With only partial compliance to local debridement, chlorhexidine oral rinses, and systemic metronidazole therapy, alveolar bone loss resulted in tooth mobility necessitating extraction of 2 involved teeth. This case illustrates the continuum of necrotizing ulcerative infections of the periodontium in the severely immunosuppressed patient. The implications of these oral manifestations of HIV infection are discussed.

Abstract
A large number of studies attest to the frequency of oral disease in those with HIV infection. Most show that hairy leukoplakia and pseudomembranous candidiasis are the commonest lesions in those with HIV infection and AIDS, with higher prevalence and incidence rates correlating with falling CD4 counts and disease progression. HIV-infected individuals with oral candidiasis or hairy leukoplakia progress to AIDS more rapidly than matched controls without these lesions. Oral candidiasis and hairy leukoplakia increase with time since seroconversion. On the other hand, parotid enlargement in children appears to be associated with slower progression to AIDS. As a consequence of these and other observations, oral lesions are widely included in natural history studies, staging and classification schemes for HIV infection. In addition to their role in the diagnosis of HIV infection and as indicators of the progression of HIV disease, oral lesions are used as clinical correlates of CD4 counts and as criteria for entry into clinical trials.
