Dental plaque microbial profiles of children from Khartoum, Sudan, with congenital heart defects

Comparative Clinical Study on Periodontal Health Status and Early Diagnosis of Periodontal Diseases Quantified through Clinical Periodontal Indices on a Group of Children and Adolescents with and without Cardiovascular Diseases

It is well known that bacterial plaque is the main etiological factor that causes the appearance of periodontal diseases and carious disease. Periodontal diseases can affect children and adolescents and are manifested in the form of gingivitis, but also the early form of chronic periodontitis as well as aggressive marginal periodontitis associated with local or general factors. Early periodontitis is frequently undiagnosed by clinicians due to a lack of knowledge of the specific symptoms. Certain systemic diseases, such as cardiovascular diseases, can create favorable conditions for the appearance and progression of severe manifestations of periodontal disease; also, recent research highlights that individuals with periodontal disease present an increased risk of developing cardiovascular diseases. Children with congenital or acquired cardiovascular diseases are at increased risk for complications resulting from the growth of microorganisms in the oral cavity, presenting a risk of infective endocarditis. The specific aim was to highlight the existing differences between the periodontal health of children with cardiovascular diseases and that of children without these diseases. The analyzed group included 124 patients, represented by children and adolescents, aged between 7 and 17 years, who were divided into four subgroups depending on the presence or absence of cardiovascular diseases and periodontal disease. A specialized clinical examination was performed for each patient, and periodontal clinical parameters were quantified (plaque index, gingival bleeding index, gingival index, community periodontal index of treatment needs) and associated with the diagnosis of general condition. Patients diagnosed with periodontal disease underwent specialized treatment and were called to a control visit 3 months after treatment. Statistical analysis showed significant differences between subgroups with much higher values of clinical parameters for patients with cardiovascular disease. Also, the response to the treatment was better in the case of patients in the control subgroup without cardiovascular diseases. The present study highlighted the interaction of three factors in the progression of periodontal diseases: subgingival microbiota, immune system response and environmental factors.

The Bacterial Oral Microbiome in Children with Congenital Heart Disease: An Extensive Review

Children with congenital heart disease have poorer oral health compared with healthy children. Oral diseases, such as dental caries and gingivitis, are associated with the oral microbiome. The objective of this review was to find evidence of differences in the bacterial colonization of the oral cavity of children with congenital heart disease (CHD) versus healthy children. A literature review was conducted according to predetermined criteria, including the need for controlled clinical trials. Half of the 14 studies that met the inclusion criteria reported significant differences in bacterial colonization in children with congenital heart disease. A variety of influencing factors were discussed. There is some evidence for alterations in the oral microflora as a result of physiopathological and treatment-related factors in children with CHD, but additional research is required to validate these findings.

Congenital Heart Diseases and Periodontal Diseases—Is There a Link?

An understanding in the field of periodontal medicine explains the fact that the oral cavity serves as a niche for numerous pathogenic microorganisms. When these microorganisms or their by-products disseminate to the various parts of the body, they are capable of triggering diseases characterized by an altered host immune-inflammatory response in the anatomically distinct organ. This mechanism is reported in the propagation of cardiovascular diseases with respect to periodontal medicine. Abundant amount of literature suggests an association between atherosclerotic cardiovascular disease and periodontal diseases. However, there is very less data available to highlight the association between periodontal disease and non-atherosclerotic cardiovascular disease, such as congenital anomalies of the heart. This review outlines the relationship between periodontal diseases and congenital heart diseases and also helps us understand whether the presence of periodontal disease can worsen the preexisting congenital cardiac disease.

Dental caries prevalence in children with congenital heart disease - a systematic review

AIM

Poor oral health is related with bacteraemia that may lead to endocarditis in children with congenital heart disease (CHD). The aim of this study was to conduct a systematic literature review to compare caries prevalence in children (<18 years of age) with CHD with healthy children.

MATERIAL AND METHODS

A literature search of studies from two online databases (Pubmed (MEDLINE) and Scopus) published from January 2000 to October 2019 using Medical subject heading terms Congenital Heart Disease, Congenital Heart Defect, and Caries was done, and manual search from the reference lists of selected publications. PICO (Patient/Population, Intervention, Comparison group, and Outcome) criteria was applied. Quality of the publications was assessed with the modified Newcastle-Ottawa scale.

RESULTS

The search resulted in 151 articles of which nine fulfilled the inclusion criteria. Caries prevalence was significantly higher in children with CHD compared to healthy children in three out of nine studies. Information on predisposing background factors was limited but difference in caries prevalence was not attributed to SES. The quality of the studies varied.

CONCLUSIONS

Although evidence is limited, the current literature indicates that children with CHD experience a higher caries prevalence compared to healthy children.

Perioperative infections in congenital heart disease

BACKGROUND

Perioperative infections have significant consequences for children with congenital heart disease (CHD), which can manifest as acute or chronic infection followed by poor growth and progressive cardiac failure. The consequences include delayed or higher-risk surgery, and increased postoperative morbidity and mortality.

METHODS

A systematic search for studies evaluating the burden and interventions to reduce perioperative infections in children with CHD was undertaken using PubMed.

RESULTS

Limited studies conducted in low- to middle-income countries demonstrated the large burden of perioperative infections among children with CHD. Most studies focussed on infections after surgery. Few studies evaluated strategies to prevent preoperative infection or the impact of infection on decision-making around the timing of surgery. Children with CHD have multiple risk factors for infections including delayed presentation, inadequate treatment of cardiac failure, and poor nutrition.

CONCLUSIONS

The burden of perioperative infections is high among children with CHD, and studies evaluating the effectiveness of interventions to reduce these infections are lacking. As good nutrition, early corrective surgery, and measures to reduce nosocomial infection are likely to play a role, practical steps can be taken to make surgery safer.
