Interleukin (IL)-34 has recently been identified as an alternative ligand for colonystimulating factor-1 receptor and plays an important role in osteoclastogenesis. The aim of this study was to assess and compare IL-34 levels in gingival crevicular fluid (GCF) and plasma in obese individuals in the presence or absence of periodontal disease and to determine whether they showed a correlation with disease severity. Forty patients aged between 25 and 40 yr were enrolled and categorized into 4 groups: 10 non-obese patients with healthy periodontium (Group I); 10 obese patients with healthy periodontium (Group II); 10 non-obese patients with chronic periodontitis (Group III); and 10 obese patients with chronic periodontitis (Group IV). Demographic variables such as age and body mass index score were recorded and assessed, together with clinical periodontal parameters such as the gingival index, probing pocket depth, and clinical attachment level scores in all groups. The GCF and plasma levels of IL-34 were quantified using enzyme-linked immunosorbent assay. The results showed that the mean IL-34 concentrations in GCF or plasma were highest in Group IV, followed by Group III, Group II, and Group I, with the difference among them being statistically significant (p<0.05). These results suggest that obese individuals with periodontitis have higher GCF and plasma IL-34 levels than non-obese individuals with healthy periodontium. This suggests IL-34 as a potential inflammatory marker of periodontal disease and obesity.

Interleukin-34 (IL-34), an alternative ligand for macrophage colony-stimulating factor receptor, plays an important role in osteoclastogenesis. The aim of this study was to analyze the effect of smoking on IL-34 levels in gingival crevicular fluid (GCF) and plasma in individuals with healthy periodontium and chronic generalized periodontitis (CP). A total of 60 individuals ranging in age from 25 to 55 years were enrolled in the study. The participants were divided into 4 groups: Group A, 30 samples (15 GCF and 15 plasma) obtained from 15 non-smokers with healthy periodontium; Group B, 30 samples (15 GCF and 15 plasma) from 15 smokers with healthy periodontium; Group C, 30 samples (15 GCF and 15 plasma) from 15 non-smokers with CP; and Group D, 30 samples (15 GCF and 15 plasma) from 15 smokers with CP. The Gingival Index and probing depth scores, together with the Clinical Attachment Level, were assessed in each group as clinical periodontal parameters. Levels of IL-34 in GCF and plasma were quantified using enzyme linked immunosorbent assay. The results showed that the mean IL-34 concentrations in GCF and plasma were highest in Group D, followed by Group C, Group B, and Group A, and the difference among them was statistically significant (p<0.05). The relatively elevated IL-34 levels observed here in smokers with CP suggest that this cytokine offers a potential inflammatory marker of periodontal disease in smokers.
