Antimicrobial photodynamic therapy in the nonsurgical treatment of periodontitis in patients with HIV infection: a systematic review and meta-analysis. Lasers Med Sci 2024; 39:155. [PMID: 38865020 DOI: 10.1007/s10103-024-04087-y] [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: 08/29/2023] [Accepted: 05/15/2024] [Indexed: 06/13/2024]
Abstract
The aim of this systematic review and meta-analysis (SRM) was to evaluate the effectiveness of the adjunctive use of antimicrobial photodynamic therapy (aPDT) in non-surgical periodontal treatment (NSPT) in subjects with Human Immunodeficiency Virus (HIV) and periodontitis. This SRM was registered in PROSPERO (CRD42023410180) and followed the guidelines of PRISMA 2020. Searches were performed in different electronic databases. Risk of bias was performed using the Cochrane Risk of Bias tool (RoB 2.0) for randomized clinical trials (RCT). Meta-analysis was performed using Rev Man software. The mean difference (MD) measure of effect was calculated, the random effect model was applied with a 95% confidence interval, and heterogeneity was tested by the I2 index. The certainty of the evidence was rated using GRADE. A total of 1118 records were screened, and four studies were included. There was a greater reduction in the microbial load of periodontopathogens after NSPT with aPDT. Meta-analysis showed that probing depth (post 3 and 6 months) and clinical attachment loss (post 6 months) were lower for the aPDT-treated group than the NSPT alone: MD -0.39 [-0.74; -0.05], p = 0.02; MD -0.70 [-0.99; -0.41], p < 0.0001; MD -0.84 [-1,34; -0.34], p = 0.0001, respectively. Overall, the studies had a low risk of bias and, the certainty of evidence was rated as moderate. It is suggested that aPDT is a promising adjuvant therapy, showing efficacy in the reduction of the microbial load and in some clinical parameters of individuals with periodontitis and HIV.

Abstract
Stenotrophomonas maltophilia (S. maltophilia) is an intrinsically drug-resistant and biofilm-forming bacteria causing infections in immunocompromised humans. This study reports the isolation of five S. maltophilia strains from saliva and gingival crevicular fluid (GCF) of AIDS patients with periodontitis in São Paulo, Brazil, showing resistance to ceftazidime, strong biofilm formation capacity and a close genetic relationship. The presence of S. maltophilia strains in saliva and CGF of patients with AIDS and periodontitis is a concern for the presence and persistence of intrinsically resistant bacteria in the oral environment, enhancing the risk for the development of severe infections in immunocompromised patients.

Abstract
BACKGROUND Following HIV-1 infection and antiretroviral therapy, the development of periodontal disease was shown to be favored. However, the influence of HIV-1 infection on the periodontal microbiota after nonsurgical periodontal debridement (NSPD) needs a broad comprehension. This work aimed to compare the subgingival microbiological content of HIV-infected and control patients with periodontitis undergoing NSPD. METHODS The bacterial profile of subgingival biofilm samples of HIV-1-infected (n = 18) and control (n = 14) patients with periodontitis was assessed using 16S rRNA gene sequencing. The samples were collected at baseline, 30 and 90 days after NSPD. The taxonomic analysis of gingival microbiota was performed using a ribosomal RNA database. The microbiota content was evaluated in the light of CD4 cell count and viral load. RESULTS Both HIV and control groups showed similar stages and grades of periodontitis. At baseline, the HIV group showed higher alpha diversity for both healthy (HS) and periodontal sites (PS). Streptococcus, Fusobacterium, Veillonella and Prevotella were the predominant bacterial genera. A low abundance of periodontopathogenic bacteria was observed, and the NSPD induced shifts in the subgingival biofilm of HIV-infected patients, leading to a microbiota similar to that of control patients. CONCLUSION Different subgingival microbiota profiles were identified - a less diverse microbiota was found in HIV-1-infected patients, in contrast to a more diverse microbiota in control patients. NSPD caused changes in the microbiota of both groups, with a greater impact on the HIV group, leading to a decrease in alpha diversity, and produced a positive impact on the serological immune markers in HIV-1-infected patients. Control of periodontitis should be included as part of an oral primary care, providing the oral health benefits and better control of HIV-1 infection. This article is protected by copyright.

Abstract
BACKGROUND Despite combined antiretroviral therapy (cART), total cure of immunodeficiency virus type 1 (HIV-1) infection remains elusive. Chronic periodontitis (CP) is strongly associated with HIV-1 infection. This condition is characterized by an intense inflammatory infiltrate mainly constituted of immune cells which in turn may be a valuable source of HIV-1 reactivation. This study aimed to determine if gingival tissue could act as a reservoir for HIV-1. METHODS Twelve HIV-1-infected patients with CP and 12 controls (no HIV-1-infection and no CP) were evaluated in a cross-sectional study. RNA viral load and interleukin (IL) levels were determined in blood plasma and saliva. Histological sections of gingival tissue were stained with fluorescent antibodies against p24 antigen and different cellular biomarkers. RESULTS In 6 of the 12 patients, HIV RNA load was detected, despite cART; in three of them, expression of viral RNA was also detected in saliva. The levels of IL-2, IL-6 and IL-12 were higher in blood and saliva of HIV-infected patients with CP than controls. HIV-1 p24 antigen was detected by Immunostaining in gingival biopsies of 10 of the 12 patients but in no control. Immune markers for T cells and antigen-presenting cells were also identified in most patients and some controls. CONCLUSION These preliminary data showing the detection of HIV-1 p24 antigen in the gingival biopsies of a significant part of HIV-1 infected patients with CP under cART together with the presence of immune cells, plead for the existence of a HIV-1 reservoir in the gingival tissue of this population.

Abstract
Periodontitis is a chronic inflammatory disease with a complex underlying immunopathology. Cytokines, as molecular mediators of inflammation, play a role in all stages of disease progression. T helper 17 (Th17) cells are thought to play a role in periodontitis. Th17 cell development and maintenance requires a pro-inflammatory cytokine milieu, with many of the cytokines implicated in the pathogenesis of periodontitis. Serum and saliva are easily accessible biofluids which can represent the systemic and local environment to promote the development of Th17 cells. Here we review human clinical studies that investigate IL-1β, IL-4, IL-6, IL-10, IL-17A, IL-17F, IL-21, IL-22, IL-23, IL-25, IL-31, IL-33, IFN-γ, sCD40L and TNF-α in serum and saliva in periodontitis. We highlight their putative role in the pathogenesis of periodontitis and place them within a wider context of animal and other clinical studies.

Abstract
OBJECTIVES Research has shown inconsistent patterns of patients' HIV serostatus disclosure to their dentists. Common barriers to disclosure have included confidentiality concerns, fear of treatment refusal, and discrimination. This study evaluated the prevalence of HIV serostatus disclosure to the dentist, whether the frequency of dental care utilization is associated with disclosure, and reasons for nondisclosure among women living with HIV. METHODS We administered a cross-sectional oral health survey to 1,526 women living with HIV in the Women's Interagency HIV Study including questions regarding HIV serostatus disclosure to dentists. Logistic regression models were used to analyze the association between dental care utilization (at least annually versus less than annually) and HIV serostatus disclosure to dentists. RESULTS Overall, 83 percent of women reported that they disclosed their HIV serostatus to their dentist. The most common reasons for nondisclosure were: a) the dentist did not ask, b) believing that the dentist did not need to know, and c) not having a consistent dentist. In the multivariable logistic regression model, at least annual dental care utilization, compared to less than annual, led to a 59 percent reduction in the odds of HIV nondisclosure to the dentist. DISCUSSION Study findings highlight that dentists who see their patients infrequently should consider methods for overcoming barriers to HIV nondisclosure and the possibility that their patient's HIV serostatus is undisclosed. Educating women living with HIV about how disclosure to dentists is a critical component of their dental assessment and treatment, and how preventive dental treatment can improve overall health outcomes, is important.

Abstract
Peroxisome proliferator activated receptor γ (PPARγ) is a member of the nuclear receptor family of transcription factors, which involved in inflammation regulating and bone remodeling. Rare studies explored the effects of PPARγ on mineralization and differentiation in cementoblasts. To explore the potential approaches to repair the damaged periodontal tissues especially for cementum, the present study aims to investigate the effects and the regulating mechanism of PPARγ on mineralization and differentiation in cementoblasts. Murine cementoblast cell lines (OCCM-30) were cultured in basic medium for 24 hours/48 hours or in mineralization medium for 3/7/10 days, respectively at addition of dimethyl sulphoxide, rosiglitazone (PPARγ agonist), GW9662 (PPARγ antagonist), lithium chloride (LiCl), tumor necrosis factor-α (TNF-α), or respective combination. Expression of mineralization genes alkaline phosphatase (ALP), runt related transcription factors 2 (RUNX2), and osteocalcin (OCN) were detected by quantitative real-time polymerase chain reaction or/and Western blot. ALP staining and alizarin red staining were used to evaluate the mineralization in OCCM-30 cells. The change of β-catenin expression and translocation in cytoplasm/nucleus was analyzed by Western blot and immunofluorescence. The results showed that PPARγ agonist rosiglitazone improved the expression of ALP, RUNX2, and OCN, deepened ALP staining, increased mineralized nodules formation, and decreased β-catenin expression in the nucleus. LiCl, an activator of the Wnt signaling pathway, inhibited the expression of mineralization genes and reversed the upregulated expression of mineralization genes resulted from rosiglitazone. Under inflammatory microenvironment, rosiglitazone not only suppressed the expression of interleukin-1β caused by TNF-α, but improved the expression of mineralization genes in OCCM-30 cells. In conclusion, PPARγ could promote mineralization and differentiation in cementoblasts via inhibiting the Wnt/β-catenin signaling pathway, which would shed new light on the treatment of periodontitis and periodontal tissue regeneration.
