Estimation of Pentraxin 3 and Levels in Patients with Rheumatoid Arthritis and Periodontitis- An Observational Study.

INTRODUCTION

Periodontal diseases are inflammatory in nature involving interplay between the bacterial plaque and the micro-organisms, with the response of the host playing a pivotal role in either attenuating or eliminating the disease. Rheumatoid Arthritis (RA) is also a chronic inflammatory disease which shares common risk factors with periodontitis. and Pentraxin 3 (an acute inflammatory protein) have been observed to be associated with both the diseases.

AIM

This study was done to determine if there was any association between and Pentraxin 3 levels in patients with RA and Chronic Periodontitis in comparison with Healthy controls.

MATERIALS AND METHODS

This observational study was conducted on 90 subjects (42 Males and 48 Females) aged between 30-60 years. The subjects were selected from the out patient ward of a tertiary referral care hospital. The selected subjects were equally divided into three groups. Group I: Comprising of 30 patients with RA and chronic periodontitis who were in turn, subdivided into Group I- A (n=15) -Patients just diagnosed with RA and Group I- B (n=15) Patients under medications for more than three months. Group II: Patients with Chronic Periodontitis (n=30) and Group III: Healthy Controls (n=30) Intergroup comparison for continuous data was done by One-way analysis of variance test followed by Bonferroni's post-hoc test. Intragroup comparison for continuous data was done by paired t-test.

RESULTS

Intergroup comparison between Group I and Group II did not show any statistical difference pertaining to the clinical parameters except for the Gingival Index (GI) which was found to be higher in Group II (Mean= 2.07) when compared to Group I (Mean=1.59). Intragroup comparison between Group IA and Group IB was statistically significant for GI, Plaque Index (PI), and Clinical Attachment Levels (CAL). Intragroup comparison between Group I-A and Group I-B showed that both and Pentraxin 3 Levels were higher in Group I- A.

CONCLUSION

In this study, it was observed that there was a positive association between and Pentraxin 3 levels in patients with rheumatoid arthritis and periodontitis.
