Mucosal Vaccination

Approximately 9 out of 10 adults have some form of periodontal disease, an infection-induced inflammatory disease of the tooth-supporting tissues. The initial form, gingivitis, often remains asymptomatic, but this can evolve into periodontitis, which is typically associated with halitosis, oral pain or discomfort, and tooth loss. Furthermore, periodontitis may contribute to systemic disorders like cardiovascular disease and type 2 diabetes mellitus. Control options remain nonspecific, time-consuming, and costly; largely relying on the removal of dental plaque and calculus by mechanical debridement. However, while dental plaque bacteria trigger periodontal disease, it is the host-specific inflammatory response that acts as main driver of tissue destruction and disease progression. Therefore, periodontal disease control should aim to alter the host’s inflammatory response as well as to reduce the bacterial triggers. Vaccines may provide a potent adjunct to mechanical debridement for periodontal disease prevention and treatment. However, the immunopathogenic complexity and polymicrobial aspect of PD appear to complicate the development of periodontal vaccines. Moreover, a successful periodontal vaccine should induce protective immunity in the oral cavity, which proves difficult with traditional vaccination methods. Recent advances in mucosal vaccination may bridge the gap in periodontal vaccine development. In this review, we offer a comprehensive overview of mucosal vaccination strategies to induce protective immunity in the oral cavity for periodontal disease control. Furthermore, we highlight the need for additional research with appropriate and clinically relevant animal models. Finally, we discuss several opportunities in periodontal vaccine development such as multivalency, vaccine formulations, and delivery systems.

This comprehensive review of the literature aimed to investigate the interplay between the oral microbiome, oral cavity conditions, and host immune response in Diabetes mellitus (DM). Moreover, this review also aimed to investigate how DM related risk factors, such as advanced age, hyperglycemia, hyperlipidemia, obesity, hypertension and polycystic ovary syndrome (PCOS), act in promoting or modifying specific mechanisms that could potentially perpetuate both altered systemic and oral conditions. We found that poorly controlled glycemic index may exert a negative effect on the immune system of affected individuals, leading to a deficient immune response or to an exacerbation of the inflammatory response exacerbating DM-related complications. Hyperglycemia induces alterations in the oral microbiome since poor glycemic control is associated with increased levels and frequencies of periodontal pathogens in the subgingival biofilm of individuals with DM. A bidirectional relationship between periodontal diseases and DM has been suggested: DM patients may have an exaggerated inflammatory response, poor repair and bone resorption that aggravates periodontal disease whereas the increased levels of systemic pro-inflammatory mediators found in individuals affected with periodontal disease exacerbates insulin resistance. SARS-CoV-2 infection may represent an aggravating factor for individuals with DM. Individuals with DM tend to have low salivary flow and a high prevalence of xerostomia, but the association between prevalence/experience of dental caries and DM is still unclear. DM has also been associated to the development of lesions in the oral mucosa, especially potentially malignant ones and those associated with fungal infections. Obesity plays an important role in the induction and progression of DM. Co-affected obese and DM individuals tend to present worse oral health conditions. A decrease in HDL and, an increase in triglycerides bloodstream levels seem to be associated with an increase on the load of periodontopathogens on oral cavity. Moreover, DM may increase the likelihood of halitosis. Prevalence of impaired taste perception and impaired smell recognition tend to be greater in DM patients. An important interplay among oral cavity microbiome, DM, obesity and hypertension has been proposed as the reduction of nitrate into nitrite, in addition to contribute to lowering of blood pressure, reduces oxidative stress and increases insulin secretion, being these effects desirable for the control of obesity and DM. Women with PCOS tend to present a distinct oral microbial composition and an elevated systemic response to selective members of this microbial community, but the association between oral microbiome, PCOS are DM is still unknown. The results of the studies presented in this review suggest the interplay among the oral microbiome, oral cavity conditions, host immune response and DM and some of the DM associated risk factors exist. DM individuals need to be encouraged and motivated for an adequate oral health care. In addition, these results show the importance of adopting multidisciplinary management of DM and of strengthening physicians-dentists relationship focusing on both systemic and on oral cavity conditions of DM patients.

The aim of this study is to assess the association of periodontal disease and COVID 19. Coronavirus have been announced pandemic along the globe by the WHO, which have severely affected every countries healthcare framework and health care profession­als globally. Due to this pandemic every individual facing severe problems both economically and emotionally. The similarity seen on inflammatory response pathway shows there is a potential relationship between COVID-19 and Periodontitis are related. Considering the relationship, significant importance should be given to maintain periodontal health, maintaining careful and good oral hygiene in the COVID-19 situation. There is also chance of feasibility that periodontal disease can be susceptible for an individual’s COVID-19 unfavourable outcomes. This relationship shows the interrelation among periodontal disease and COVID-19 and between the cytokine relationship which advices in improving hygiene in oral cavity during this COVID situation. And it is found individuals with periodontal disease have high risk of getting COVID associated unfavourable consequences.

This study evaluated the effectiveness of a newly developed dental hygiene chew for dogs, with and without a natural antimicrobial additive, compared with a reference diet. Efficacy was determined by measuring the severity of gingivitis and the accumulation of dental plaque and calculus in dogs after 4-weeks of being fed the different dietary regimens. Dogs fed a single daily dental chew had significantly less gingivitis (P = 0.02), plaque (P = 0.0004), and calculus (P = 0.0001) compared with dogs in the control group that were fed an identical diet but received no chews. The inclusion of the antimicrobial agent did not improve the efficacy of the product. The dental hygiene chews tested in this study have potential to help reduce the incidence of periodontal disease in dogs.

The article deals the results of searches on the prevalence, etiological factors and pathogenic mechanisms of certain dental diseases in cats. The analysis of literary data of domestic and foreign scientists testifies, that among dental diseases in cats the largest group consists of periodontal diseases. The changed type of feeding, the imbalance of the ration, the lack of complete self-cleaning of the teeth lead to a decrease in the immunobiological reactivity of the organism. Incorrect bite, deformation of the teeth, parodontopathy, etc. cause an animal's discomfort, cause complications in the cardiovascular, respiratory and other systems. Periodontopathies are registered, for the most part, in adult cats. The etiological factors of periodontal diseases are local and general. The starting mechanism of the inflammatory process in the peritoneal tissues is a violation of the ratio of various associations of microorganisms, the balance of which depends on the presence of dental plaque and dental stone. The results of research of many scientists testify that periodontal diseases are accompanied by complicated and profound disorders at the morphological level, as well as systemic changes in metabolic, biochemical, immunological and endocrine reactions. In the absence of prevention, untimely diagnosis of periodontal disease and the treatment of dental sick cats irreversible changes in the dental system of animals are developed. Diseases of the oral cavity in cats is one of the main causes of loss of teeth, the emergence of deformations, the formation of chronic foci beyond the oral cavity and the development of various forms of somatic pathology. Therefore, to prevent the development of periodontal disease and their complications in cats it is necessary to develop effective measures for the prevention of diseases of the parolont, and for stomatologically sick animals - methods of treatment with the use of new medicinal substances.

SUMMARY Schistosomiasis, caused by trematode blood flukes of the genus Schistosoma, is recognized as the most important human helminth infection in terms of morbidity and mortality. Infection follows direct contact with freshwater harboring free-swimming larval (cercaria) forms of the parasite. Despite the existence of the highly effective antischistosome drug praziquantel (PZQ), schistosomiasis is spreading into new areas, and although it is the cornerstone of current control programs, PZQ chemotherapy does have limitations. In particular, mass treatment does not prevent reinfection. Furthermore, there is increasing concern about the development of parasite resistance to PZQ. Consequently, vaccine strategies represent an essential component for the future control of schistosomiasis as an adjunct to chemotherapy. An improved understanding of the immune response to schistosome infection, both in animal models and in humans, suggests that development of a vaccine may be possible. This review considers aspects of antischistosome protective immunity that are important in the context of vaccine development. The current status in the development of vaccines against the African (Schistosoma mansoni and S. haematobium) and Asian (S. japonicum) schistosomes is then discussed, as are new approaches that may improve the efficacy of available vaccines and aid in the identification of new targets for immune attack.

The past decades demonstrated that saliva and its components represent a remarkable diagnosis fluid with valuable clinical uses for both oral and systemic diseases. At the same time it is well established that oxidative stress is involved in a wide number of pathologies, including periodontitis. The specific aim of the present study which included 50 subjects is to determine if saliva can be used in clinical settings to correlate oxidative stress and tissue destruction markers with the severity of periodontal disease. An important oxidative stress marker - 8-hydroxydesoxyguanosine (8-OHdG) and a collagen degradation marker - beta-crosslaps (b-CTX) were quantified in both saliva and gingival crevicular fluid (GCF) using ELISA kits and were found to be significantly increased in the chronic periodontitis group when compared to respective controls (p[0.05). At the same time positive correlations were observed between whole saliva and gingival crevicular fluid (p[0.05). Significant correlations were also determined between GCF and salivary markers and clinical parameters of periodontal disease. Present results demonstrate that saliva and its components can successfully be used in clinical settings and represents a reliable tool for assessing periodontal disease severity.

Over the past several decades, studies have demonstrated the existence of bi-directional relationships between periodontal disease and systemic conditions. Periodontitis is a polymicrobial and multifactorial disease involving both host and environmental factors. Tissue destruction is primarily associated with hyperresponsiveness of the host resulting in release of inflammatory mediators. Pro-inflammatory cytokines play a major role in bacterial stimulation and tissue destruction. In addition, these cytokines are thought to underlie the associations between periodontitis and systemic conditions. Current research suggests that increased release of cytokines from host cells, referred to as the cytokine storm, is associated with disease progression in patients with coronavirus disease 2019 (COVID-19). An intersection between periodontitis and pulmonary disease is biologically plausible. Hence, we reviewed the evidence linking COVID-19, cytokines, and periodontal disease. Plaque control is essential to prevent exchange of bacteria between the mouth and the lungs, reducing the risk of lung disease. Understanding these associations may help identify individuals at high risk and deliver appropriate care at early stages.

Background:A close association between periodontal disease and Ankylosing spondylitis (AS) has long been specualted. Both diseases are characterized by dysregulation of the host inflammatory response, leading to further destruction of soft and hard connective tissue with there being evidence of increased levels of TNF-α and various interleukins in both patients of AS and periodontitis.Objectives:The aim of this systematic review was to appraise the available literature exploring the relationship between AS and periodontal disease.Methods:We searched Medline & Embase databases (from their inception till October 2019) using appropriate combinations of following search items with limits ‘(English, Human)’; Ankylosing spondylitis, spondyloarthritis, spondyloarthropathies, spondyloarthritides, spinal disease, musculoskeletal disease, Rheumatic disease AND periodontitis, periodontal disease, periodontoses, parodontoses, chronic periodontitis, gum disease, gingivitis, oral health, dental health, plaque index, bleeding on probing, probing pocket depth, clinical attachment loss. This search was supplemented by the manual search of bibliographies of articles selected and conferences proceedings of EULAR. Only be reviews, observational study of cross-sectional, cohort or case control type on adult patients with AS were selected. Data was extracted from a predesigned proforma. A close association between periodontal disease and Ankylosing spondylitis (AS) has long been specualted. Both diseases are characterized by dysregulation of the host inflammatory response, leading to further destruction of soft and hard connective tissue with there being evidence of increased levels of TNF-α and various interleukins in both patients of AS and periodontitis.Results:A total number of 984 articles were identified and 12 were selcted for detailed appraisal (Figure 1, PRISMA flow chart). They were all case control studies. The prevalence of periodontitis ranged from 38% to 88% in patients with AS whereas in the control group from 26% to 71 % in controls. Out of 12 studies, two showed significant changes in Plaque Index (PI), two studies showed altered Pocket Probing Depth (PPD), three showed significant increased in Clinical Attachment Loss (CAL) and increased Bleeding On Probing (BOP) was seen in 2 studies. In 7 studies, periodontitis was seen in a significant number of patients with AS (P<0.05). All studies reported that the prevalence of periodontal disease in AS patients was higher as compared to non-AS patients.Conclusion:Our systematic review found an association between AS and periodontal disease. Patients with AS show higher prevalence of periodontitis and a poor oral hygiene as compared to healthy controls. At practice level, this systematic review underscores the need for a collaboration between dentists and rheumatologist.Disclosure of Interests:None declared
