HIV-Infected Individuals Do Not Present Significant Differences regarding Periodontal Status: A Systematic Review and Meta-Analysis. Int J Dent 2024; 2024:5559610. [PMID: 39224190 PMCID: PMC11368558 DOI: 10.1155/2024/5559610] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/26/2024] [Revised: 07/18/2024] [Accepted: 07/25/2024] [Indexed: 09/04/2024] Open
Abstract
Objective To evaluate, through a systematic literature review, whether periodontal status in HIV-infected individuals is different from those non-HIV-infected. Materials and Methods A systematic search for published observational studies within six electronic databases and grey literature was conducted, PROSPERO database number CRD42020160062. Results from studies reporting clinical periodontal parameters: probing pocket depth, bleeding on probing, clinical attachment level, plaque index, and gingival index, in HIV- and non-HIV-infected individuals were reviewed. The quality of the assessment was evaluated according to the Joanna Briggs Institute Appraise Checklist. Results Twenty-three observational studies met the eligibility criteria and were included for analysis. The qualitative analysis indicated similarities in periodontal parameters within both groups, with no significant mean difference (MD) within both groups regarding clinical periodontal parameters; severe heterogeneity was also detected. Conclusions No significant differences were found in the periodontal profile of HIV-infected and non-HIV-infected individuals. However, the high heterogeneity among the studies calls for caution in interpreting these findings. Further investigations using standardized methods for periodontal evaluation are needed to clarify the association between HIV infection and periodontal conditions.

Abstract
BACKGROUND The study objectives were to determine tooth loss prevalence and to investigate the relationship between tooth loss and potential risk factors among adult dentate HIV+ patients on newer antiretroviral therapy (ART) regimens. METHODS Health records of 450 human immunodeficiency virus (HIV)-infected individuals were surveyed. Eighty-eight records of dentate HIV+ individuals with full-mouth periodontal charting and intra-oral periapical radiographs were identified. We collected data on demographics, systemic risk factors, oral health, and HIV disease measures. Caries exposure and alveolar bone loss (ABL) were radiographically assessed. RESULTS Eighty-eight percent of patients showed tooth loss. Patients with ABL ≥15% had a higher number of missing teeth (p < .01). Stepwise regression analyses indicated that tooth loss was positively associated with age (β = 0.45, p < .01) and ABL (β = 0.39, p < .01). By contrast number of years on ART was negatively associated with tooth loss (β = -0.28, p < .05). CONCLUSIONS Tooth loss remains prevalent among HIV+ patients, and periodontal disease is a significant contributor. The number of years on ART seem to improve oral health behavior and reduce tooth loss.

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
Mechanical reduction of infectious bacteria by using physical instruments is considered the principal therapeutic strategy for periodontal disease; addition of antibiotics is adjunctive. However, local antibiotic treatment, combined with conventional mechanical debridement, has recently been shown to be more effective in periodontitis subjects with type 2 diabetes. This suggests that some bacteria may invade the inflamed inner gingival epithelium, and mechanical debridement alone will be unable to reduce these bacteria completely. Therefore, we tried to establish infected organ culture models that mimic the inner gingival epithelium and aimed to see the effects of antibiotics in these established models. Mouse dorsal skin epithelia were isolated, and periodontal bacteria were injected into the epithelia. Infected epithelia were incubated with test antibiotics, and colony-forming ability was evaluated. Results indicated that effective antibiotics differed according to injected bacteria and the bacterial combinations tested. Overall, in organ culture model, the combination of amoxicillin or cefdinir and metronidazole compensate for the effects of less effective bacterial combinations on each other. This in vitro study would suggest effective periodontal treatment regimens, especially for severe periodontitis.

Abstract
BACKGROUND AND OBJECTIVE To compare the subgingival microbial diversity between non-HIV-infected and HIV-infected individuals with chronic periodontitis using denaturing gradient gel electrophoresis (DGGE). MATERIAL AND METHODS Thirty-two patients were selected: 11 were HIV-infected and 21 were non-HIV-infected, and all had chronic periodontitis. Periodontal measurements included probing depth, clinical attachment level, visible supragingival biofilm and bleeding on probing. Subgingival biofilm samples were collected from periodontal sites (50% with probing depth ≤ 4 mm and 50% with probing depth ≥ 5 mm) and whole-genomic-amplified DNA was obtained. The DNA samples were subjected to amplification of a 16S rRNA gene fragment using universal bacterial primers, followed by DGGE analysis of the amplified gene sequences. RESULTS The non-HIV-infected group presented higher mean full-mouth visible supragingival biofilm (p = 0.004), bleeding on probing (p = 0.006), probing depth (p < 0.001) and clinical attachment level (p = 0.001) in comparison with the HIV-infected group. DGGE analysis revealed 81 distinct bands from all 33 individuals. Banding profiles revealed a higher diversity of the bacterial communities in the subgingival biofilm of HIV-infected patients with chronic periodontitis. Moreover, cluster and principal component analyses demonstrated that the bacterial community profiles differed between these two conditions. High interindividual and intra-individual variability in banding profiles were observed for both groups. CONCLUSION HIV-infected patients with chronic periodontitis present greater subgingival microbial diversity. In addition, the bacterial communities associated with HIV-infected and non-HIV-infected individuals are different in structure.

Abstract
AIM This study compared lactoferrin (LF) levels in the gingival crevicular fluid (GCF) and saliva between HIV-infected and noninfected patients with chronic periodontitis. METHODS For each subject, LF levels were analyzed in one shallow site (SS; PD ≤3 mm), one deep site (DS; PD >5 mm) and in resting whole saliva. Two groups, 28 HIV-infected and 10 noninfected, were selected. RESULTS Although the salivary LF levels were higher in HIV-infected than in noninfected individuals, especially in AIDS patients, this was not statistically significant (P > 0.05). Subgingival LF levels for SS and DS were lower among HIV-infected individuals, although AIDS patients showed the lowest levels. Age, smoking, gender, T CD4 lymphocytes levels and viral load did not influence subgingival LF levels, neither for SS nor for DP. Positive fungal culture was observed in 24 HIV-infected patients, but only observed in one in the control group. Overall, LF concentration was significantly higher in DS than SS, both in HIV-infected and noninfected individuals (P < 0.05) and salivary LF levels were always higher than GCF levels. CONCLUSION The data indicate that LF levels in the GCF and saliva are not different between HIV-infected and noninfected patients with chronic periodontitis.

Abstract
BACKGROUND This study investigates the association between detectable plasmatic human immunodeficiency virus (HIV) viral load (HVL) and high levels of periodontal- and non-periodontal-related microorganisms in the subgingival microbiota of individuals with HIV. METHODS Thirty-seven individuals with HIV were divided into two groups: 1) detectable HVL (n = 15); and 2) undetectable HVL (n = 22). Subgingival biofilm samples were obtained, and the levels of 35 microbial species were determined by the checkerboard DNA-DNA hybridization method. Periodontal clinical measures and laboratory and sociodemographic data were also registered. χ(2) test, Fisher exact test, and Mann-Whitney U test were used to compare groups. Multilevel ordinal regression models were used to test the association between HVL and the levels of 35 microbial species in subgingival biofilm, adjusted for confounders. RESULTS Of the 35 species studied, 11 (31.4%) showed higher mean levels in the detectable HVL group than undetectable HVL group (P <0.001). These species included Actinomyces naeslundii II, Actinomyces israelii, Actinomyces odontolyticus, Veillonella parvula, Capnocytophaga gingivalis, Eikenella corrodens, Campylobacter concisus, Porphyromonas gingivalis, Tannerella forsythia, Treponema denticola, and Candida albicans. Significant associations between detectable HVL and high levels of microorganisms, adjusted for confounders, were observed for A. naeslundii I, Actinomyces gerencseriae, C. gingivalis, E. corrodens, C. concisus, Prevotella nigrescens, T. forsythia, and Dialister pneumosintes. CONCLUSION Detectable plasmatic HVL in individuals with HIV was associated with elevated levels of known periodontal pathogens, such as P. nigrescens, T. forsythia, and E. corrodens, as well as C. concisus, C. gingivalis, and D. pneumosintes in the subgingival biofilm.

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
BACKGROUND A study undertaken in 1992-1993 identified that HIV-infected dental patients were substantially disadvantaged with regard to the social impact of their oral disease. The oral pain experienced by HIV-positive patients prior to the introduction of combination antiretroviral therapy (cART) was attributable to specific features of HIV-related periodontal disease and other oral manifestations of HIV such as candida infections and xerostomia. A repeat of this study in 2009-2010 provided additional information in the post-cART era. METHODS Data were collected from three sources: the 2009-2010 HIV-positive sample, the National Survey of Adult Oral Health (NSAOH) and the original 1992-1993 study. Collation of data was by clinical and radiographic oral examination. Information about the social impact of oral conditions was obtained from the Oral Health Impact Profile. RESULTS The caries experience of the 2009-2010 HIV-positive sample was improved with statistical significance for both mean DMFT and mean DT, while the presence of HIV-related periodontal disease still occurs. Statistically significant improvements were achieved for prevalence and severity of oral health related quality of life. CONCLUSIONS The need for timely access to oral health care with a focus on prevention is essential for HIV-positive individuals whose health is impacted by chronic disease, smoking and salivary hypofunction.

Abstract
BACKGROUND The purpose of the present study is to verify a possible association between herpesviruses and periodontal pathogens in individuals with human immunodeficiency virus (HIV) and periodontitis. METHODS Twenty-seven patients with HIV and chronic periodontitis and 23 patients with HIV and gingivitis were included in the study. Probing depth, clinical attachment loss, gingival index, and plaque index were recorded. Blood, saliva, and subgingival plaque were processed for viral and bacterial identification. Bacteria were identified by 16S rRNA-based polymerase chain reaction and viruses by the nested polymerase chain reaction. RESULTS For the chronic periodontitis group, Epstein-Barr (EBV)-1 (70.4%) and Tannerella forsythia (Tf) (51.8%) presented higher detection in subgingival plaque and saliva (81.5% and 40.7%, respectively) than in blood (22% and 0%, respectively) (P <0.005 and P <0.0001, respectively). Porphyromonas gingivalis (Pg) was more frequent in subgingival plaque (77.7%; P <0.0001). In the gingivitis group, Pg and human cytomegalovirus (HCMV) presented higher frequency in subgingival plaque (95.6% and 91.3%, respectively; P <0.0001 and P = 0.004). Tf and EBV-1 were detected more frequently in subgingival plaque (47.8% and 78.3%, respectively) and saliva (52.2% and 52.2%, respectively; P = 0.004 and P <0.005) than in blood. EBV-1, EBV-1-HCMV, and presence of different viruses presented an association with periodontitis in saliva. CONCLUSIONS No association was detected for herpesviruses and periodontal pathogens in patients who are HIV-positive with periodontitis. EBV-1 and coinfection (EBV-1-HCMV) were associated with patients who are HIV-positive with periodontitis.

METHODS A total of 172 subjects were distributed into two HIV-seropositive groups (37 chronic periodontitis [H+CP+] and 35 periodontally healthy [H+CP-] individuals) and two HIV-seronegative groups (49 chronic periodontitis [H-CP+] and 51 periodontally healthy [H-CP-] subjects). Subgingival samples were collected from six sites with the deepest probing depth in the periodontitis groups and six random sites in the groups with periodontal health. All HIV-infected patients had undergone highly active antiretroviral therapy (HAART) for at least 2 years. The presence and levels of 33 bacterial species were detected by DNA probes and the checkerboard method. Kruskal-Wallis and Mann-Whitney tests were used to seek for significant differences among and between groups. RESULTS H-CP+ patients showed significantly more periodontal destruction and inflammation than H+CP+ patients, whereas H+CP- subjects presented a greater percentage of sites with bleeding than H-CP- subjects (P <0.01). Patients who were HIV seronegative showed higher prevalence and levels of most bacterial species than HIV seropositive patients. Periodontal pathogens including Tannerella forsythensis, Porphyromonas gingivalis, Prevotella nigrescens, Eubacterium nodatum, Fusobacterium nucleatum, and Selenomonas noxia were more frequently detected in H-CP+ subjects compared to H+CP+ and controls. In contrast, Enterococcus faecalis and Acinetobacter baumannii were more commonly found in HIV-infected than in non-HIV-infected subjects (P <0.05). CONCLUSION Putative periodontal pathogens are more prevalent in the subgingival microbiota of HIV-seronegative patients with chronic periodontitis, whereas species not usually associated with periodontitis are detected in higher frequency in HIV-seropositive subjects under HAART.

Abstract
Enterotoxigenic Bacteroides fragilis (ETBF) strains are associated with diarrhea disease in farm animals and young children. In this study, the bft gene subtyping from ETBF strains recovered from one immunodeficient and two immunocompetent children with diarrhea were determined. Thirteen ETBF strains were isolated and by using a multiplex-PCR their bft subtypes were determined. All 13 ETBF strains harbored the bft-1 subtype and by AP-PCR they were clustered in the same group I. This study shows that ETBF strains can be present in acute diarrhea and that bft-1 subtype is often present in these organisms. However, further studies are needed to evaluate the role of this bft-1 subtype in the pathogenesis of diarrhea.

Abstract
BACKGROUND Controversial data regarding the association between immunosuppression and prevalence/ severity of periodontal diseases in HIV infection have been reported. Thus, the aim of this study was to test the hypothesis that lower T CD4 lymphocyte levels are not related to a higher prevalence of chronic periodontitis in HIV-infected Brazilians undergoing highly active anti-retroviral therapy (HAART). METHODS Sixty-four HIV-infected patients under HAART were classified as having chronic periodontitis; i.e., > or = three sites with probing depth (PD) and/or clinical attachment level (CAL) > or = 5 mm or periodontal healthy (no sites with PD > 3 mm and/or CAL > 4 mm). All subjects received conventional periodontal therapy. Bleeding on probing, plaque accumulation, PD, and CAL were registered at six sites/tooth at baseline and 4 months after therapy. Epidemiological features and levels of T CD4 lymphocytes were obtained from medical records. Significance of differences in periodontal clinical parameters within and between groups were determined using Wilcoxon signed-rank and Mann-Whitney or independent sample t tests. Associations between T CD4 levels and clinical parameters were determined using the chi square test. RESULTS Sixty-one percent of the HIV-infected patients represented AIDS cases, although 69% of them were periodontally healthy. The overall T CD4 lymphocyte mean levels was 333 +/- 254 cells/mm3 and viral load was 12,815 +/- 24,607 copies/mm3. Yet the prevalence of chronic periodontitis was relatively low (36%). In addition, patients with periodontitis presented a moderate disease (mean PD = 2.2 +/- 0.10; mean CAL = 2.6 +/- 0.13) and responded successfully to periodontal therapy. These subjects showed higher levels of T CD4 cells, but lower counts of neutrophils than periodontally healthy patients. Among periodontally healthy and chronic periodontitis patients, 41.7% and 22.9%, respectively, had low levels of T CD4 lymphocytes. No significant differences between periodontal status and epidemiological and immunological parameters were observed. CONCLUSION Based on these results, the hypothesis that lower T CD4 lymphocyte levels are not associated with higher prevalence of chronic periodontitis in HIV-infected Brazilians under HAART cannot be rejected.

Abstract
The prevalence of subgingival Candida species was studied in 52 human immunodeficiency virus (HIV)-positive and 42 HIV-negative children. Candida was cultured from 22 (42.3%) and 3 (7.1%) HIV-infected and control children, respectively. C. albicans was the most common Candida species isolated from HIV-infected children, followed by C. dubliniensis, C. glabrata, and C. tropicalis. In the HIV-positive group, the prevalence of Candida isolation was significantly higher in children who presented with low CD4(+)-T-lymphocyte counts, elevated viral loads, and gingivitis.

Abstract
OBJECTIVE The aim of this study was to determine the subgingival microbiota of HIV-infected patients with chronic periodontitis and different T CD4 lymphocyte levels under HAART. STUDY DESIGN 64 HIV+ patients (mean age 34.5 +/- 7.3; 75% males) were distributed into Group I: chronic periodontitis (> or = 3 sites with probing pocket depth (PPD) and/or clinical attachment level (CAL) > or = 5 mm); and Group II: periodontal health (no sites with PPD > 3 mm and/or CAL > 4 mm). All subjects received conventional periodontal therapy. Periodontal clinical parameters were evaluated at 6 sites/tooth in all teeth at baseline and 4 months after therapy. The levels of T CD4 were obtained from the patient's medical record. Subgingival plaque samples were taken from the 6 sites with the largest pocket depth in each subject of Group I, and 6 randomly selected sites in subjects of Group II. The presence of 22 subgingival species was determined using the checkerboard DNA-DNA hybridization method. Significant microbiological differences within and among groups were sought using Wilcoxon signed-rank and Mann-Whitney tests, respectively. Relationships between T CD4 levels and microbiological parameters were determined using Kruskal-Wallis test. RESULTS Sixty-one percent of the HIV-infected patients represented AIDS cases, although 69% of them were periodontally healthy. The T CD4 lymphocyte mean level was 333 cells/mm3 and viral load was 12,815 +/- 24,607 copies/mm3. Yet, the prevalence of chronic periodontitis was relatively low (36%). Several periodontal pathogens, in particular T. forsythensis (P < .05), were more prevalent in HIV-positive patients with periodontitis than in HIV-positive subjects with periodontal health. Most of the species decreased in frequency after therapy, particularly P. gingivalis (P < .05). E. faecalis and F. nucleatum were significantly more prevalent in the subgingival microbiota of patients with chronic periodontitis and lower levels of T CD4 (P < .05), while beneficial species tended to be more frequently detected in individuals with T CD4 counts over 500 cells/mm3. CONCLUSION The subgingival microbiota of HIV-infected patients with chronic periodontitis include a high prevalence of classical periodontal pathogens observed in non-infected individuals. Furthermore, the severe immunosuppression seems to favor the colonization by these species, as well as by species not commonly found in the subgingival microbiota.

Abstract
Selective immunoglobulin A (IgA) deficiency is the most common of the primary immunodeficiencies with a frequency of 1/300-1/3000, depending on the screened population. As secretory IgA (SIgA) has a protective role in mucosal surfaces from invasion of microorganisms, it is thought that IgA-deficient subjects are susceptible to periodontal diseases and oral manifestations. Previous studies show contradictory results, concerning the involvement of the individuals' periodontium with IgA deficiency. The aim of this study was to investigate and compare the oral manifestations in IgA-deficient subjects with controls. Eleven selective IgA-deficient subjects aged 3-18 years with serum IgA levels <10 mg dl(-1) and 11 age-sex-matched healthy children as the controls entered the study. Oral mucosal investigation, dental caries, plaque accumulation and periodontal status were assessed. Serum immunoglobulin levels were measured by single radial immunodiffusion (SRID) method. Saliva immunoglobulins and secretory component levels were measured by enzyme linked immunosorbent assay (ELISA) methods. IgA-deficient patients had serum and saliva IgA levels less than 10 mg dl(-1) and 10 microg ml(-1), respectively, but other serum immunoglobulin levels were normal and saliva immunoglobulin M (IgM) levels were increased, compared with controls. There were no significant differences in oral manifestations between IgA-deficient subjects and controls, which may be a result of compensatory increase of saliva IgM or other non-immunological defence factors in saliva. Thus, it is not necessary to evaluate IgA and SIgA in all the patients with oral and dental lesions and it is thought that it is better to investigate other factors.

Abstract
BACKGROUND Periodontal disease has been previously associated with human immunodeficiency virus (HIV) infection, and HIV infection has been considered a modifier of periodontal disease. The aim of this study was to report the prevalence and severity of periodontal disease in a population of HIV-positive individuals and to investigate the association between clinical periodontal indices and the stage of HIV disease, as expressed by CD4 cell counts. METHODS Thirty-nine male HIV-positive patients were recruited and a medical history was taken. To evaluate periodontal disease, probing depth (PD), attachment level loss (AL), bleeding index (BI), and modified gingival index (MGI) were recorded. Associations between the above indices and CD4 counts were examined. RESULTS Immunocompromised patients (with CD4 cell counts < 200 cells/microl) showed significantly lower BI and fewer sites with PD and AL > 4 mm compared to patients with CD4 cell counts > 200 cells/microl. When patients with CD4 counts < 500 cells/microl were considered alone, a correlation was observed between CD4 cell counts and BI (r2 = 0.1617, P = 0.0463), MGI (r2 = 0.2123, P = 0.0204), and number of sites with AL > 4 mm (r2 = 0.1469, P = 0.056). CONCLUSIONS Severely immunocompromised HIV-positive patients showed less severe gingival inflammation than expected. Patients with CD4 cell counts > 500 cells/microl showed no association between CD4 cell count and periodontal indices.

Abstract
BACKGROUND We previously reported an increased rate of progression of periodontal disease over an 18-month period in human immunodeficiency virus (HIV)-positive subjects compared to controls. The mechanism for disease progression and rapid tissue loss was unknown. Data on the microbiological studies failed to show any significant difference in the microbial characteristics of the periodontal lesions in HIV-positive patients compared to HIV-negative controls. Immunological analysis had identified neutrophils as an important component of the host defense against periodontal infection, especially against rapid tissue loss. Serum IgG reactivities to periodontal pathogens in HIV-positive patients with periodontitis were reduced. Other data provided circumstantial evidence to suggest that IgG subclass (IgG2) specific antibody might assist bacterial clearing in periodontal infection. The aim of the current study was to examine the specific IgG subclass antibody response to a panel of periodontopathic organisms: Actinobacillus actinomycetemcomitans (Aa), Porphyromonas gingivalis (Pg), Prevotella Intermedia (Pi), Fusobacterium nucleatum (Fn), Campylobacter rectus (Cr), and Bacteroides forsythus (Bf) in HIV-positive patients compared to HIV-negative controls. METHODS Sera from 120 HIV-positive patients (40 periodontitis, 69 gingivitis, and 11 no oral diseases) were tested for IgG subclass specific antibody response to the above listed 6 organisms using enzyme-linked immunosorbent assay. Data were compared with those obtained from 40 HIV-negative control subjects (35 periodontitis, 2 gingivitis, and 3 no oral diseases). RESULTS In the HIV-positive group, a consistently high response rate was found in IgG1 to all the bacteria tested. In addition, high levels of IgG3 and IgG4 to Pg and IgG1 and IgG2 to Pi were also present. However, no significant difference was detected among the periodontitis, gingivitis, and no oral disease subgroups. When the periodontitis patients from the HIV-positive group were compared to the HIV-negative group, no difference in the antibody levels and response rates was noted. CONCLUSION We conclude that in HIV-positive patients, the specific IgG subclass antibody response to periodontopathic organisms was similar to that of HIV-negative subjects.

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
AIM The aim of the present study was to investigate the long-term results of periodontal supportive therapy in HIV-seropositive and HIV-seronegative patients. MATERIAL AND METHODS Baseline examination of 18 HIV-seropositive patients (14 males and four females, median age of 29.7 years) revealed the following periodontal diagnoses: eight patients with linear gingival erythema, four patients with necrotizing periodontitis, five patients with conventional gingivitis and one patient with chronic periodontitis. In the HIV-seronegative group, out of 16 patients (12 males and four females, median age 35.5 years), one patient presented with conventional gingivitis and 15 patients with chronic periodontitis. Periodontal therapy and maintenance care consisted of supra- and subgingival removal of plaque and calculus and instruction in oral hygiene. Based on the individual patient's needs, the mechanical therapy was repeated. RESULTS In the test group, the mean maintenance period was 22.7 +/- 9.4 months (range 11.0-37.4) and in the control group, 48.9 +/- 32.0 months (range 9.3-110.8). In the test group, the mean PlI (1.1 +/- 0.8) remained at the same level (1.1 +/- 0.5; p = 0.73, Wilcoxon sign rank test, p < 0.05) throughout the observation period, the mean GI was reduced from 1.6 +/- 0.5 to 1.4 +/- 0.4 (p = 0.18), the mean PPD was reduced from 2.9 +/- 0.3 to 2.8 +/- 0.2 (p = 0.15) and the mean PAL (3.1 +/- 0.5) remained unaltered as well (3.1 +/- 0.4; p = 0.83). None of these differences was statistically significant. In the control group, PPD (3.0 +/- 0.4) and PAL (3.0 +/- 0.5) were significantly reduced: PPD = 2.7 +/- 0.2 (p = 0.0003) and PAL = 2.9 +/- 0.5 (p = 0.0034). CONCLUSION In HIV-seropositive patients, attachment level can be maintained. However, oral hygiene and compliance are the key factors for this.

Abstract
BACKGROUND, AIMS The aims of this study were to investigate the prevalence of periodontitis, the prevalence of black-pigmented anaerobes and the genotypes of Porphyromonas gingivalis and Prevotella intermedia present in HIV-infected and control subjects in a heterosexual Thai population. METHOD 50 AIDS patients and 50 control subjects were included in the study. Their periodontal condition was examined by assessment of bleeding on probing, attachment loss and probing depth, and presence of erythema around 6 teeth (16, 21, 24, 36, 41, 44). Subgingival plaque was collected from the mesiobuccal sites of these teeth and was cultured anaerobically for black-pigmented bacteria. Species were characterised using biochemical profiles and total protein profiles. Genotyping of each isolate was performed using PCR techniques. RESULTS There was little clinical evidence of HIV-associated periodontitis in the HIV-positive subjects and no difference was found in the prevalence or genotype distribution of black-pigmented anaerobes between HIV-infected and control subjects. CONCLUSIONS These data suggest lack of severe periodontal destruction due to HIV-infection in Thailand and that these subjects are not colonised by more numerous or characteristic clones of certain putative periodontal pathogens.

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
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
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
Three vertically HIV-infected children showed, in addition to oral candidiasis, HIV-gingivitis, which healed on antimycotic treatment. The intense linear gingival erythema of a fourth child was also clinically evaluated as a possible form of erythematous oral candidiasis. Direct microscopic examination of material from the gingival lesions of the latter disclosed yeast cells and hyphae. Subsequent culture, biochemical and serological tests identified the yeast as Candida dubliniensis. As the patient was on long-term prophylaxis with fluconazole, ketoconazole was administered and led to a good clinical response. This is the first report implicating this new Candida species as a pathogen in linear gingival erythema in a HIV-positive individual. The case reports presented provide evidence that linear gingival erythema may be of candidal origin. Further clinical and laboratory observations are required to establish whether this condition constitutes a variant of erythematous candidiasis associated with paediatric HIV infection.

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
Serum samples were obtained from 44 HIV-seropositive (HIV+) and 37 HIV-seronegative (HIV-) persons that were grouped according to periodontal status. Serum IgG and IgA reactivities towards Streptococcus mutans, Actinobacillus actinomycetemcomitans, Porphyromonas gingivalis. Prevotella intermedia, Prevotella nigrescens and Fusobacterium nucleatum were measured by means of ELISA. HIV+ persons with chronic marginal periodontitis showed significantly lower IgG reactivities to the periodontal pathogens A. actinomycetemcomitans, P. gingivalis, P. intermedia and F. nucleatum as compared with their HIV- counterparts (p < 0.05). Specific serum IgA reactivities were similar in the two periodontitis groups, except for P. nigrescens where the HIV+ group with chronic marginal periodontitis had lower values than their systemically healthy counterparts (p < 0.05). The results indicate that HIV infection affects the humoral serum immune responses against bacteria in dental plaque; the depressed antibody responses may contribute to the increased susceptibility for periodontal infections in HIV-infected patients.

Abstract
Individuals in Tanzania who have limited access to medical and dental treatment provide an opportunity to study the natural association between periodontal condition and HIV infection and the stage of infection. 119 HIV-infected adult individuals and 73 individuals with AIDS from the AIDS Clinical Trial Clinic at Muhimbili Medical Centre (MMC) in Dar-es-Salaam participated as cases. Mean age was 35.3 and 35.1 years, respectively. 156 individuals with a mean age of 28.3 years, confirmed as HIV-seronegative, served as controls. There were no significant differences in bleeding on probing, pocket formation or attachment loss among the HIV-seronegative individuals, HIV-seropositive and AIDS patients. We applied multiple logistic regression to calculate odds ratios for presence of periodontal conditions adjusting for age, gender and DMFT. Our odds ratios did not reveal any significant associations between bleeding on probing, pocket formation or attachment loss with regard to lymphocyte and CD4+ T-cell counts among the HIV-infected individuals and AIDS patients. When associations were investigated with regard to HIV-serostatus (HIV-seronegative, HIV-seropositive or AIDS), our adjusted odds ratios were insignificant, too. In fact, most odds ratios were close to 1. Thus, our study supports recent views that the presence, extent and severity of periodontal disease among HIV-infected individuals, may be less that hitherto thought.

Abstract
A review of periodontal disease as a manifestation of HIV infection suggests a shift in emphasis over the past 5 years. Initially the focus was on newly described forms of periodontal disease (i.e., HIV-associated gingivitis or linear gingival erythema (LGE); HIV-associated periodontitis or necrotizing ulcerative periodontitis (NUP). While the clinical definition of LGE varies from study to study, an association between LGE and Candida infection has been described. Furthermore, the prevalence of NUP is quite low and this disorder is associated with severe immunosuppression. In contrast, the focus today is on the accelerated rate of chronic adult periodontitis occurring in seropositive patients. While the organisms that characterize adult periodontitis in seronegative individuals are present in subgingival plaque from seropositive individuals, reports suggest that atypical pathogens are also present (i.e., Mycoplasma salivarium, Enterobacter cloacae). Recent studies from our laboratory have identified a novel strain of Clostridium isolated from the subgingival plaque of injecting drug users that has pathologic potential. This organism, however, was found in both seropositive and seronegative individuals in this cohort, suggesting an association with lifestyle rather than serostatus. In addition, data has been published examining the local host response in periodontitis in seropositive individuals. Distinctly elevated levels of IgG in gingival crevicular fluid (GCF) have been observed in seropositive patients. Furthermore, data from our laboratory examining inflammatory mediators in GCF (polymorphonuclear leukocyte lysosomal enzyme beta-glucuronidase and the pro-inflammatory cytokine interleukin-1 beta) suggests an altered response in patients with HIV infection. The alteration manifests as the absence of the expected strong correlation between polymorphonuclear leukocyte activity in the gingival crevice and clinical measures of existing periodontal disease, as well as elevated levels of interleukin-1 beta in sites with deeper probing depths. Therefore, it can be concluded that the progression of periodontal disease in the presence of HIV infection is dependent upon the immunologic competency of the host as well as the local inflammatory response to typical and atypical subgingival microorganisms.

Abstract
Gingival crevicular fluid (GCF) levels of the polymorphonuclear leukocyte (PMN) lysosomal enzyme beta-glucuronidase (beta G), the pro-inflammatory cytokine interleukin 1 beta (IL-1 beta), and immunoglobulins (IgA, IgG, and IgM) were examined in 16 HIV seropositive (HIV+) and 10 HIV seronegative (HIV-) injecting drug users (IDU). Each subject received a periodontal examination including assessment of probing depth, attachment level, bleeding on probing, and plaque and calculus accumulation. GCF was collected from the mesial surfaces of premolar and molar teeth using filter paper strips. Although HIV+ subjects had a significantly lower number of peripheral blood CD4+ T cells/mm3 compared to HIV- subjects, there were no significant differences in mean probing depth, percentage of sites exhibiting bleeding on probing, or plaque and calculus accumulation between HIV- and HIV+ subjects. When the GCF components were analyzed, we found no significant differences between HIV- and HIV+ subjects in GCF levels of beta G, IL-1 beta, IgA or IgM, but GCF levels of IgG were significantly increased in HIV+ subjects. When sites were categorized by probing depth, no differences in the levels of beta G, IgA, IgG, and IgM existed between sites with probing depth < or = 3 mm compared to sites with probing depth > or = 4 mm in both HIV- and HIV+ IDU. However, levels of IL-1 beta in GCF were increased in the deeper sites (> or = 4 mm) in HIV+ IDU when compared to sites with PD < or = 3 mm. Analyzing GCF constituents in relation to the CD4 cell number, no differences were found between subjects with < or = 400 or > 400 CD4 cells/mm3 with respect to the levels of IL-1 beta, IgG, and IgM. However, the level beta G was significantly decreased in the HIV+ IDU with < or = 400 CD4 cells when compared to those with > 400 CD4 cells/mm3, while levels of IgA were significantly higher in HIV+ subjects with < or = 400 CD4 cells/mm3. Our results suggest that levels of IgG, and in immunodeficient subjects IgA were increased in GCF of HIV+ IDU while decreased levels of beta G were found in immunodeficient HIV+ IDU. These findings may be local manifestations of systemic alterations and suggest that analysis of GCF may provide insight into the immune and inflammatory responses of HIV-infected individuals to periodontal microorganisms.

Abstract
In this cross-sectional study, we assessed the in vitro interleukin-2 (IL-2) producing capacity of peripheral blood mononuclear cells (PBMC) and lymphocytes from patients with different forms of periodontitis. 45 patients (12 with localised early onset periodontitis (LEOP), 20 with generalised early onset periodontitis (GEOP), and 13 with adult periodontitis (AP), and 20 periodontally healthy subjects (HS), participated in this study. PBMC and lymphocytes were isolated from the subjects and their cells were stimulated with an anti-CD3 monoclonal antibody (anti-CD3 MoAb) and the secreted IL-2 levels in the culture were bioassayed. No significant differences could be found in IL-2 producing activity of PBMC between the patients and HS group. There was wide interindividual variation and high and low "IL-2 producers" were noted. We found a LEOP patient who was a high producer of IL-2 (> mean + 8 SD) and 2 LEOP patients and a HS who were low producers of IL-2 (< mean - 1.5 SD) with their lymphocytes. Incidentally, the HS became a LEOP patient during 2 years after this study. The low IL-2 producing activity of their PBMC and lymphocytes against anti-CD3 MoAb could not be overcome by stimulation with phorbol myristate acetate and ionomycin. Thus, we found high and low IL-2 producing capacity by PBMC and lymphocytes in certain subjects and these subjects may be useful models in assessing the role of systemic IL-2 productivity associated with their progression of periodontal disease.

Abstract
OBJECTIVE Human immunodeficiency virus (HIV)-seropositive patients have frequently severe gingival inflammation and/or attachment loss. In addition many infectious diseases affect their periodontium with varying clinical manifestations. Matrix metalloproteinases seem to play a key role in physiological periodontal remodelling and pathological tissue destruction. The aim of the present study was to characterize the presence, molecular forms, cellular sources, activities, and relative amounts of fibroblast-type (matrix metalloproteinase [MMP]-1) and neutrophil (MMP-8) collagenases, as well as their potential activator stromelysin-I (MMP-3) and myeloperoxidase in saliva of HIV-seropositive patients at different phases of HIV-infection. HIV-seronegative, healthy, age-matched patients served as controls. PATIENTS AND METHODS Saliva samples were characterized by Western blotting using antibodies specific for MMP-1, MMP-3 and MMP-8. Interstitial collagenase activities were measured using quantitative sodium dodecyl sulfate (SDS)-polyacrylamide gel electrophoresis/laser densitometry assay. Myeloperoxidase was analysed using quantitative dot blotting. RESULTS Clinical and microbiological evaluation of HIV-seropositive patients' periodontium showed the presence of putative periodontopathogens ie Actinobacillus actinomycetemcomitans (Aa), Porphyromonas gingivalis (Pg), Prevotella intermedia (Pi), Peptostreptococcus micros (Psm) and Campylobacter rectus (Cr) in their periodontal pockets. The amount of Candida increased with the severity of HIV-infection. Clinical and microbiological findings of HIV-seropositive patients suggested that they have a tendency to develop periodontal disease. Interstitial collagenase activities were found to be increased in saliva of different phases of HIV-infected patients compared to the controls. Independent of the phase of HIV-infection saliva samples contained pro- and active forms of MMP-1, -3 and -8 using Western blotting. Saliva samples from healthy controls were found to contain hardly any immunoreactivities for MMP-1 or MMP-8, but considerable amounts of MMP-3 were detected. Quantitative dot blotting demonstrated increased amounts of myeloperoxidase in HIV-patients' saliva relative to controls. CONCLUSION The present results showed increased amounts of MMP-1, -3, -8 and myeloperoxidase in HIV-patients' saliva. MMP-1 and -8 may have been activated by MMP-3 and/or oxidants generated by myeloperoxidase. The increased amounts of MMPs and myeloperoxidase may reflect and directly participate in HIV-infection associated periodontitis.

Abstract
The presence of systemic disease in patients requiring periodontal therapy creates challenges for management. Alteration of treatment plans, with emphasis on physician consultation and preventive periodontal care, is frequently needed to minimize the impact of periodontal disease on the systemic condition. Conversely, detection and treatment of systemic disorders may impact upon the status of the periodontium and the success of periodontal therapy. The goal of holistic patient management is facilitated by a free flow of information between the patients and their medical and dental health care providers.

Abstract
HIV-1-associated periodontal diseases have been reported in the literature for several years. Criteria for the diagnosis of these diseases have not been universally accepted, although there are numerous papers describing the clinical entity. These case reports provide clinical and radiographic evidence of a type of periodontal disease with bone and soft tissue destruction which differentiates it from "conventional" periodontal diseases found in both HIV-1-infected patients and those not infected by the virus. It is important, from both diagnostic and therapeutic aspects, for clinicians to be able to make this distinction. The appropriate use of clinical and radiographic findings is extremely helpful in the diagnosis, particularly in the case of defining HIV-1 necrotizing ulcerative periodontitis (NUP). Whether the patterns of gingival changes and bone loss described in these case reports are specific to HIV-1-seropositive persons or rather represent severe immunosuppression requires further investigation.

Abstract
This study aimed to assess oral health status and the social impact of oral conditions among dental patients with HIV infection in comparison with general dental patients receiving public-funded care in Adelaide, South Australia. DMFT and CPITN indices were recorded by one dentist at a clinic for HIV dental patients. The data were compared with information from an existing survey of general dental patients. Social impact was assessed using the Oral Health Impact Profile questionnaire and responses from HIV dental patients were compared with responses from a telephone interview survey of Adelaide residents. HIV patients were aged 21 to 49 years (median = 34), 90.7 percent were male and 29.6 percent had stage 4 HIV infection. Oral candida was present among 32.0 percent, hairy leukoplakia among 24.1 percent, HIV gingivitis among 18.5 percent, and HIV periodontitis among 33.3 percent. The DMFT index and its components did not differ significantly between HIV and general dental patients, while CPITN scores were lower among HIV patients (p = 0.01). However social impact among HIV patients was frequent: 64.6 percent reported toothache, 43.7 percent avoided foods, and 16.7 percent avoided going out because of dental problems. HIV patients reported significantly greater levels of social impact than the Adelaide sample (p < 0.01). Patients to this clinic frequently presented with severe and disabling oral conditions which were not adequately captured using standard clinical indices.

Abstract
This study was performed to determine the type of periodontal pathology found in a group of HIV+ patients and its relation to serum levels of CD4. The sample consisted of 101 individuals: intravenous drug users (84%), homosexuals (7%), and heterosexuals (10%). Each patient was examined clinically and radiographically. Periodontal clinical parameters included gingival index and probing depth and loss of attachment on four sites per tooth. Severity of disease was defined as the most severe lesion found: gingivitis, or early, moderate, or advanced periodontitis. CD4 counts were determined on 64 of these patients. Associations between severity of the disease and gender and CD4 counts were analyzed using the Mantel Haenszel chi square test, while associations between severity and age and CD4/CD8 ratio were analyzed using the Kruskal-Wallis test. No disease was found in 14.8% of the sample, gingivitis was found in 21.8%, early periodontitis in 43.6%, moderate periodontitis in 10.9%, and advanced periodontitis in 8.9%. Linear gingival erythema (LGE) was seen in 17.8% of all patients and necrotizing periodontitis (NUP) in 4.9%. No statistically significant differences were observed between the severity of the disease and CD4 counts.

Abstract
Periodontal status was evaluated in two cohorts participating in a study of the natural history of human immunodeficiency virus (HIV) infection. One cohort consisted of 77 seropositive and 44 seronegative homosexual men, and the other cohort was comprised of 44 seropositive and 39 seronegative parenteral drug users (PDU). No differences were observed between seropositive and seronegative individuals within a cohort in terms of clinical periodontal parameters (percent of sites with > or = 4 mm probing depth, percent of sites exhibiting bleeding on probing, mean oral hygiene index). The PDU displayed more existing periodontal disease than the homosexual men. Periodontal disease in the seropositive individuals in both cohorts was not strictly related to the number of CD4+ lymphocytes. Linear gingival erythema (LGE), defined as an erythematous band of at least 2 mm extending between adjacent papilla, was observed in all 4 groups. Seropositive homosexual men displayed more LGE than seronegative homosexual men (16.6% vs. 11.4%) and seronegative PDU displayed more LGE than seropositive PDU (38.5% vs. 29.5%), but neither difference was significant. LGE tended to be related to reduced numbers of CD4+ lymphocytes, but this relationship did not reach statistical significance. A statistically-significant relationship was found between the presence of intraoral candidiasis and LGE in seropositive homosexual men: 42.9% of these subjects with candidiasis had LGE, while only 12.7% of the subjects without candidiasis had LGE (P < .05). For the seropositive PDU, 35.3% of the individuals with candidiasis had LGE and 25.9% of the subjects without candidiasis displayed LGE, but the difference was not statistically significant.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Our understanding of important stages in the pathogenesis of the human polyomavirus BK virus (BKV) and JC virus (JCV) infections is limited. In this context, nasopharyngeal aspirates from 201 children with respiratory diseases and saliva from 60 human immunodeficiency virus type 1-infected adults and 10 healthy adult controls were collected and analyzed for the presence of BKV and JCV DNA by PCR. Neither BKV nor JCV DNA was detected in the saliva specimens. We demonstrated BKV DNA, but no infectious BKV, in 2 of 201 nasopharyngeal aspirates. Each sample contained one unique rearranged noncoding control region variant of BKV. The results indicate that (i) BKV and JCV are not regularly associated with respiratory infections in children requiring hospitalization, (ii) nasopharyngeal cells are not an important site for primary replication of human polyomavirus BKV and JCV, and (iii) the salivary glands and oropharyngeal cells seem not to be involved in BKV and JCV persistence. We propose that for the polyomaviruses BKV and JCV the alimentary tract should be considered as a portal of entrance to the human organism.

Abstract
BACKGROUND Oral lesions are common findings in HIV-related disease, but little is known about their significance in predicting immune suppression among a representative group of HIV-infected persons. METHODS Oral examinations were performed on 454 patients who came to an outpatient dental clinic for dental care. CD4+ cell counts were obtained within 2 months of the examination. RESULTS In persons with a specific lesion and a CD4+ cell count below 200 cells/mm3 the corresponding mean CD4+ cell counts and predictive values were 149.5 cells/mm3 and 69.9% for candidiasis, 143.3 cells/mm3 and 70.1% for oral hairy leukoplakia, 126.0 cells/mm3 and 69.4% for xerostomia, 51.8 cells/mm3 and 95.1% for necrotizing ulcerative periodontitis, 98.7 cells/mm3 and 87.0% for long-standing herpes simplex virus infections, 66.6 cells/mm3 and 93.6% for Kaposi's sarcoma, and 33.7 cells/mm3 and 100% for major aphthous ulcers. The mean CD4+ cell count declined with increased numbers of different concurrent lesions. CONCLUSION The presence of specific oral manifestations and the number of different concurrent intraoral lesions among HIV-infected persons are associated with severe immune suppression and AIDS. Oral examinations are an essential component for early recognition of disease progression and comprehensive evaluation of HIV-infected patients.
