RESUMEN

Aim: The purpose of this study is to undertake an integrative literature review in order to determine the prevalence, etiology, and reactivation of oral HSV infection in patients receiving chemotherapy (CT). Methods: The study was carried out in the PubMed/MEDLINE, Embase, Virtual Health Library, and Scopus databases, using the descriptors "Herpes Simplex", "Viral Diseases", "Mouth", and "Antineoplastic Agents". Results: The findings suggest that HSV infection is widespread in this group of patients and can be severe. HSV infection is frequent in CT patients, and treatment should begin as soon as it is feasible, utilizing antivirals to avoid future difficulties, as patients are immunocompromised. Conclusion: It is critical for health professionals to be fully informed on the dangers and treatment choices available, with the most appropriate therapy for each circumstance. Furthermore, more recent research with acceptable methodological rigor is required to better quantify the prevalence of HSV in these patients.

RESUMEN

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.

RESUMEN

The role of the oral microbiota in the overall health and in systemic diseases has gained more importance in the recent years, mainly due to the systemic effects that are mediated by the chronic inflammation caused by oral diseases, such as periodontitis, through the microbial communities of the mouth. The chronic infection by the human immunodeficiency virus (HIV) interacts at the tissue level (e.g. gut, genital tract, brain) to create reservoirs; the modulation of the gut microbiota by HIV infection is a good example of these interactions. The purpose of the present review is to assess the state of knowledge on the oral microbiota (microbiome, mycobiome and virome) of HIV-infected patients in comparison to that of HIV-negative individuals and to discuss the reciprocal influence of HIV infection and oral microbiota in patients with periodontitis on the potential establishment of a viral gingival reservoir. The influence of different clinical and biological parameters are reviewed including age, immune and viral status, potent antiretroviral therapies, smoking, infection of the airway and viral coinfections, all factors that can modulate the oral microbiota during HIV infection. The analysis of the literature proposed in this review indicates that the comparisons of the available studies are difficult due to their great heterogeneity. However, some important findings emerge: (i) the oral microbiota is less influenced than that of the gut during HIV infection, although some recurrent changes in the microbiome are identified in many studies; (ii) severe immunosuppression is correlated with altered microbiota and potent antiretroviral therapies correct partially these modifications; (iii) periodontitis constitutes a major factor of dysbiosis, which is exacerbated in HIV-infected patients; its pathogenesis can be described as a reciprocal reinforcement of the two conditions, where the local dysbiosis present in the periodontal pocket leads to inflammation, bacterial translocation and destruction of the supporting tissues, which in turn enhances an inflammatory environment that perpetuates the periodontitis cycle. With the objective of curing viral reservoirs of HIV-infected patients in the future years, it appears important to develop further researches aimed at defining whether the inflamed gingiva can serve of viral reservoir in HIV-infected patients with periodontitis.

RESUMEN

OBJECTIVE: Lysosome-associated membrane protein 3 (LAMP3) misexpression in salivary gland epithelial cells plays a causal role in the development of salivary gland dysfunction and autoimmunity associated with Sjögren's disease (SjD). This study aimed to clarify how epithelial LAMP3 misexpression is induced in SjD. METHODS: To explore upstream signaling pathways associated with LAMP3 expression, we conducted multiple RNA sequencing analyses of minor salivary glands from patients with SjD, submandibular glands from a mouse model of SjD, and salivary gland epithelial cell lines. A hypothesis generated by the RNA sequencing analyses was further tested by in vitro and in vivo assays with gene manipulation. RESULTS: Transcriptome analysis suggested LAMP3 expression was associated with enhanced type I interferon (IFN) and IFNγ signaling pathways in patients with SjD. In vitro studies showed that type I IFN but not IFNγ stimulation could induce LAMP3 expression in salivary gland epithelial cells. Moreover, we discovered that LAMP3 overexpression could induce ectopic Toll-like receptor 7 (TLR-7) expression and type I IFN production in salivary gland epithelial cells both in vitro and in vivo. TLR-7 knockout mice did not develop any SjD-related symptoms following LAMP3 induction. CONCLUSION: Epithelial LAMP3 misexpression can be induced through enhanced type I IFN response in salivary glands. In addition, LAMP3 can promote type I IFN production via ectopic TLR-7 expression in salivary gland epithelial cells. This positive feedback loop can contribute to maintaining LAMP3 misexpression and amplifying type I IFN production in salivary glands, which plays an essential role in the pathophysiology of SjD.

RESUMEN

OBJECTIVES: To evaluate the accuracy of major salivary gland ultrasonography (SGUS) in relation to minor salivary gland biopsy (mSGB) in the diagnosis of Sjögren's syndrome (SS). METHODS: A systematic review and meta-analysis were performed. Ten databases were searched to identify studies that compared the accuracy of SGUS and mSGB. The risk of bias was assessed, data were extracted, and univariate and bivariate random-effects meta-analyses were done. RESULTS: A total of 5000 records were identified; 13 studies were included in the qualitative synthesis and 10 in the quantitative synthesis. The first meta-analysis found a sensitivity of 0.86 (95% CI: 0.74-0.92) and specificity of 0.87 (95% CI: 0.81-0.92) for the predictive value of SGUS scoring in relation to the result of mSGB. In the second meta-analysis, mSGB showed higher sensitivity and specificity than SGUS. Sensitivity was 0.80 (95% CI: 0.74-0.85) for mSGB and 0.71 (95% CI: 0.58-0.81) for SGUS, and specificity was 0.94 (95% CI: 0.87-0.97) for mSGB and 0.89 (95% CI: 0.82-0.94) for SGUS. CONCLUSIONS: The diagnostic accuracy of SGUS was similar to that of mSGB. SGUS is an effective diagnostic test that shows good sensitivity and high specificity, in addition to being a good tool for prognosis and for avoiding unnecessary biopsies. More studies using similar methodologies are needed to assess the accuracy of SGUS in predicting the result of mSGB. Our results will contribute to decision-making for the implementation of SGUS as a diagnostic tool for SS, considering the advantages of this method.

RESUMEN

OBJECTIVE: To evaluate the efficacy of topical tacrolimus offered on a custom tray to treat desquamative gingivitis (DG). STUDY DESIGN: Eighteen patients with symptomatic DG related to oral lichen planus (OLP) or mucous membrane pemphigoid (MMP) were selected, of which 13 completed the study. Periodontal treatment was followed by the fabrication of a custom silicone tray to apply a tacrolimus gel formulation (0.1%). Clinical evaluation (complaint of pain and burning - visual analog scale from 0 to 10; and the presence of erythema, desquamation, vesicle/blister, erosion, ulcer, and bleeding) was performed by the same examiner on day 1, and every 15 days for 90 days. RESULTS: Total remission was found in 4 patients (30.76%). Partial remission was found in 69.24% of the patients, classified with an excellent (30.76%), good (30.76%), and regular (7.69%) recovery, respectively. There was a reduction of about 60% in pain and 65% in burning sensation complaints. Wilcoxon test revealed significant differences between pre- and post-treatment pain and burning sensation symptoms (P < .01). CONCLUSION: Topical application of 0.1% tacrolimus gel was effective in the treatment of DG in controlling pain and burning sensation, leading to the clinical remission of gingival lesions in patients with OLP and MMP.

RESUMEN

OBJECTIVE: to analyze the prevalence of ideal cardiovascular health (CVH) in the Brazilian adult population based on the 2019 National Health Survey. METHODS: this was a population-based cross-sectional study (n = 77,494); prevalence and respective 95% confidence intervals (95%CI) of ideal CVH (seven metrics achieved simultaneously) and by individual metrics (four behavioral and three biological metrics), as defined by the American Heart Association, were estimated. RESULTS: only 0.5% (95%CI 0.4;0.6) of the study population presented ideal CVH, with higher prevalence among those with higher level of education (1.3%; 95%CI 0.9;1.6) and residents in urban areas (0.6%; 95%CI 0.5;0.7); the prevalence of behavioral and biological metrics was 0.7% (95%CI 0.6;0.8) and 63.3% (95%CI 62.7;63.9) respectively. CONCLUSION: the prevalence of ideal CVH was very low, highlighting the need for public policies aimed at promotion, surveillance and CVH care in the Brazilian adult population.

RESUMEN

Hydroxychloroquine (HCQ) is a lysosomotropic agent that is commonly used for treating Sjögren's disease (SjD). However, its efficacy is controversial because of the divergent response to the drug among patients. In a subgroup of SjD patients, lysosome-associated membrane protein 3 (LAMP3) is elevated in expression in the salivary glands and promotes lysosomal dysregulation and lysosome-dependent apoptotic cell death. In this study, chloroquine (CQ) and its derivative HCQ were tested for their ability to prevent LAMP3-induced apoptosis, in vitro and on a mouse model of SjD. In addition, efficacy of HCQ treatment was retrospectively compared between high LAMP3 mRNA expression in minor salivary glands and those with LAMP3 mRNA levels comparable with healthy controls. Study results show that CQ treatment stabilized the lysosomal membrane in LAMP3-overexpressing cells via deactivation of cathepsin B, resulting in decreased apoptotic cell death. In mice with established SjD-like phenotype, HCQ treatment also significantly decreased apoptotic cell death and ameliorated salivary gland hypofunction. Retrospective analysis of SjD patients found that HCQ tended to be more effective in improving disease activity index, symptom severity and hypergammaglobulinemia in patients with high LAMP3 expression compared those with normal LAMP3 expression. Taken together, these findings suggested that by determining salivary gland LAMP3 mRNA level, a patient's response to HCQ treatment could be predicted. This finding may provide a novel strategy for guiding the development of more personalized medicine for SjD.

RESUMEN

BACKGROUND: Periodontitis (PDT) has gained attention in the literature with the increase in life expectancy of people living with HIV on combined antiretroviral therapy (cART). Thus, the search for inflammatory biomarkers could be useful to understand the pathophysiology of chronic oral diseases in the cART era. OBJECTIVE: The aim of this study was to evaluate the impact of non-surgical periodontal therapy (NSPT) on clinical parameters of PDT, Candida spp. count and expression of lactoferrin (LF) and histatin (HST) in saliva and gingival crevicular fluid (GCF) of HIV-infected patients. METHODS: Bleeding index (BI), probing depth (PD), clinical attachment level (CAL), colonyforming units (CFUs) of Candida spp, and LF and HST levels were measured in saliva and GCF of both groups at three different times: baseline (before treatment), and 30 and 90 days after the NSPT. Clinical, mycological and immunoenzymatic analyses were also performed. RESULTS: Twenty-two HIV-infected patients and 25 non-HIV-infected patients with PDT participated in the study. NSPT was effective in improving periodontal clinical parameters, including ≤ 4 sites with PD ≤ 5mm and BI ≤ 10%. Significant change in oral Candida spp. count occurred neither between the two groups nor after NSPT. And the salivary and GCF levels of LF and HST were not influenced by the NSPT; by contrast, except for salivary LF, HST and LF were shown to exhibit significantly higher levels in HIV-infected than in non-HIV-infected patients. CONCLUSION: NSPT was effective in improving periodontal disease parameters in HIV-infected patients, but did not affect LF and HST expression in saliva and GCF of HIV-infected patients.

RESUMEN

Focal dermal hypoplasia (FDH), also known as Goltz syndrome, consists of an unusual genodermatosis that affects tissues of ectodermal and mesodermal origin and various organs and systems, especially skin, bones, eyes, and oral cavity. While systemic manifestations of FDH have been well documented, the oral manifestations have not been extensively discussed. We present a 22-year-old female patient with history of FDH that showed a variety of systemic and oral manifestations. FDH was diagnosed at birth based on cutaneous alterations. Extra and intraoral examination showed facial asymmetry, lip and perioral atrophy, upper lip papilloma, malocclusion, enamel hypoplasia, and gingival hyperplasia. Mucosal lesions, periodontal diseases, and malocclusion were treated by oral surgery, periodontal therapy and orthodontic treatment, respectively. Although FDH is an uncommon syndrome, health professionals should be aware of its systemic and oral manifestations to establish an early diagnosis and adequate treatment.

RESUMEN

BACKGROUND: Sjögren Syndrome (SS) is a systemic autoimmune disease with a wide spectrum of manifestations that can lead to misdiagnosis. This study describes and compares demographic, clinical, serological, and histopathological data from subjects with SS and non-Sjögren Syndrome (NSS). It also details specific features within the primary SS (pSS) and secondary SS (sSS) groups identifying sub-groups. METHODS: The sample included individuals referred to an academic medical center in Brazil for investigation of SS from 2012 to 2020. Patients were retrospectively classified as primary SS (pSS), secondary SS (sSS), or NSS, based on the American-European Consensus Group criteria (AECG-2002), after multi-professional clinical and laboratory evaluation. RESULTS: A total of 676 individuals were screened and 510 (75.4%) completed the assessments; 198 patients were classified as pSS, 149 as sSS, and 163 as NSS. Symptoms and glandular dysfunction tests were similar in the groups. Concerning pSS, extraglandular manifestations were present in 59% of patients; the elderly had more dry symptoms and peripheral neurological disorders; and 2.5% developed non-Hodgkin lymphoma. In sSS, each overlap promoted distinct clinical and laboratory variants. Several alternative diagnoses were identified as a cause of sicca complex in NSS group. CONCLUSIONS: The diagnosis of SS remains a challenge behind dryness. Up to 31% of the suspected cases had other conditions associated to the symptoms. Histopathological analysis of LSG and SSa determined the diagnostic. Aging in pSS and overlap disease in sSS were responsible for distinct phenotypes and characteristic sub-groups in SS.

RESUMEN

BMP6 is a central cytokine in the induction of Sjögren's syndrome-associated (SS-associated) secretory hypofunction. However, the upstream initiation leading to the production of this cytokine in SS is unknown. In this study, RNA ISH on salivary gland sections taken from patients with SS indicated monocytic lineage cells as a cellular source of BMP6. RNA-Seq data on human salivary glands suggested that TLR4 signaling was an upstream regulator of BMP6, which was confirmed by in vitro cell assays and single-cell transcriptomics of human PBMCs. Further investigation showed that HSP70 was an endogenous natural TLR4 ligand that stimulated BMP6 expression in SS. Release of HSP70 from epithelial cells could be triggered by overexpression of lysosome-associated membrane protein 3 (LAMP3), a protein also associated with SS in several transcriptome studies. In vitro studies supported the idea that HSP70 was released as a result of lysosomal exocytosis initiated by LAMP3 expression, and reverse transcription PCR on RNA from minor salivary glands of patients with SS confirmed a positive correlation between BMP6 and LAMP3 expression. BMP6 expression could be experimentally induced in mice by overexpression of LAMP3, which developed an SS-like phenotype. The newly identified LAMP3/HSP70/BMP6 axis provided an etiological model for SS gland dysfunction and autoimmunity.

RESUMEN

BACKGROUND: Following human immunodeficiency virus-1 (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 non-surgical periodontal debridement (NSPD) needs a broad comprehension. This work aimed to compare the subgingival microbiological content of patients infected with HIV-1 and controls (non-infected) with periodontitis undergoing NSPD. METHODS: The bacterial profile of subgingival biofilm samples of patients with HIV-1 (n = 18) and controls (n = 14) 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 and periodontal sites. 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 patients with HIV-1, leading to a microbiota similar to that of controls. CONCLUSIONS: Different subgingival microbiota profiles were identified-a less diverse microbiota was found in patients infected with HIV-1, in contrast to a more diverse microbiota in controls. 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 patients infected with HIV-1. 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.

RESUMEN

Good communication between clinicians and pathologists is a vital element in the diagnostic process, and poor communication can adversely affect patient care. There is a lack of research about communication in diagnostic oral and maxillofacial pathology. This narrative review explores different aspects of the quality of communication between clinicians and oral pathologists, with a focus on the diagnosis of oral and maxillofacial diseases. An electronic search was carried out in MEDLINE through the PubMed, Scopus, and Embase databases up to April 2021. No studies reporting communication, its adequacy or the required skills between clinicians and pathologists in oral diagnosis were found. According to studies published in medicine, strategies for improving communication skills include clinician-pathologist collaboration; a well-formatted, clear and thorough report; training in communication skills; and patient-centered care. Further studies evaluating the current practices and quality in oral and maxillofacial pathology are required to identify barriers and encourage optimal communication to facilitate diagnosis, as well as patient safety.

RESUMEN

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 patients with HIV-1 and 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 six 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 patients with HIVand CP than controls. HIV-1 p24 antigen was detected by immunostaining in gingival biopsies of 10 of the 12 patients but in no controls. 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 patients with HIV-1 and 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.

This narrative review explores different aspects of the quality of communication between clinicians and oral pathologists, with a focus on the diagnosis of oral and maxillofacial diseases. An electronic search was carried out in MEDLINE through the PubMed, Scopus, and Embase databases up to April 2021. No studies reporting communication, its adequacy or the required skills between clinicians and pathologists in oral diagnosis were found. According to studies published in medicine, strategies for improving communication skills include clinician-pathologist collaboration; a well-formatted, clear and thorough report; training in communication skills; and patient-centered care. Further studies evaluating the current practices and quality in oral and maxillofacial pathology are required to identify barriers and encourage optimal communication to facilitate diagnosis, as well as patient safety.
