Association of Elevated C-Reactive Protein with Severe Periodontitis in Hypertensive Patients in Lagos, Nigeria: A Pilot Study

Association between periodontal inflamed surface area and systemic inflammatory biomarkers among pre-dialysis chronic kidney disease patients

Background

Several studies have shown an association between chronic kidney disease (CKD) and periodontitis. However, only few studies have quantified the burden of periodontal inflammation in pre-dialysis CKD patients. The aim of this study was to determine the association between periodontal inflamed surface area (PISA) and systemic inflammatory biomarkers among pre-dialysis CKD patients.

Materials and Methods

120 pre-dialysis CKD participants were recruited into this study. 60 participants constituted Group A (those with periodontitis) while 60 participants constituted Group B (those without periodontitis). Full periodontal examination was carried out in the participants for the estimation of PISA. Blood samples also collected to determine levels of high sensitivity C-reactive protein (hsCRP) and interleukin-6 (IL-6) in all participants. Independent t-test was used to compare means of PISA, hsCRP and IL-6 levels in the two groups. Pearson correlation analysis was used to determine association between PISA and (hsCRP and IL-6).

Results

The mean value of hsCRP was significantly higher in Group A compared to Group B (3.41 mg/L vs. 2.18 mg/L). PISA moderately correlated with hsCRP (r = 0.4, P < 0.01) in both groups. hsCRP also moderately correlated with IL-6 (r = 0.6, P < 0.001) in both groups.

Conclusion

This study demonstrates that there was an association between PISA and hsCRP. Increased hsCRP level in Group A revealed the inflammatory burden imposed by periodontitis.

Periodontitis Severity Grading Scale and C-Reactive Protein: A Possible Relation

Background C-reactive protein (CRP) is the first acute-phase protein and is an exceptional investigative marker for local and systemic inflammation. The periodontitis severity grading scale (PSGS) indicates the extent of periodontal inflammation. Therefore, the aim of the study was to explore the correlation between the markers of systemic and periodontal inflammation as assessed by CRP and the PSGS in participants with periodontitis. Materials and methods The present study enrolled 85 systemically healthy participants with periodontitis. PSGS and CRP levels were measured in each participant. Descriptive and inferential statistics were applied for analysis. Results The PSGS scores ranged from 24 to 213, and the CRP levels ranged from 0.5 to 3.23 mg/l. This shows a positive correlation between the periodontal scale and CRP. A nonsignificant (p-value > 0.05) correlation exists between age and CRP score, and a significant association was seen between gender and severity of periodontitis with p-value < 0.02. A highly significant association between gender and CRP score was found with p-value < 0.001. Conclusion The level of serum CRP dramatically increased with the severity of periodontitis. The results of this study point to a highly significant correlation between markers of systemic and periodontal inflammation, as well as a strength of association between the two markers.

Relationship between high CRP and cytokines in Saudi old people with dental caries in alkharj Region, Saudi Arabia

Objective

Dental caries is one of the most common problems of the oral cavity which is frequently observed in older people. The aim of this study is to evaluate serum C-reactive proteins (CRP) levels and to identify the correlation between dental caries and CRP levels.

Methodology

The study included 12 aged patients with an average age of 65-years; the patients were diagnosed with dental caries and did not have clinical history of heart diseases, rheumatoid arthritis or any other infection. The control group consisted of 10 healthy donors with an average age of 60-years. The CRP level of positive samples was measured by using CRP Enzyme-linked immunosorbent assay-ELISA Kit.

Results

The currents study showed that only 5 out of 12 patients were CRP positive.

Conclusions

Because of study limitations, it is early to conclude of close relationship between serum CRP and dental caries from the findings of this study; however, this study will give a clearer picture to understand the relationship between serum CRP, inflammatory cytokines and dental caries.
