Inflammation mediated Osteoclastogenesis and bone resorption markers in Periodontitis subjects with and without type...

Periodontitis and type2 diabetes are chronic inflammatory diseases resulting in osteoclastogenesis and bone loss. This study investigated the effect of type2 diabetes in inflammation mediated osteoclastogenesis invitro along with bone resorption markers in subjects with and without periodontitis.

Whole blood samples were collected from periodontitis subjects with (n = 30) or without T2D (n = 30) and healthy subjects (n = 30). Isolated PBMCs were cultured to study osteoclastogenesis pathways invitro. The prime markers of RANKL signalling pathway, including TRAF6, cFos, NFATc1 and cathepsin K, were analysed by immunoblotting. Serum interleukin 6 (IL6), C- terminal telopeptide of Type I collagen (CTx), tartrate resistant acid phosphatase 5b (TRAP5b) and alkaline phosphatase (ALP) were estimated in all groups.

Our results showed that cultured PBMCs from periodontitis and T2D subjects demonstrated a higher number of TRAP positive cells compared to subjects without T2D. IL6, CTx and TRAP5b levels were significantly elevated in T2D with periodontitis, compared to normal subjects with or without periodontitis.

This study provides insights on inflammation mediated bone remodelling T2D in periodontitis leading to alveolar bone loss. Understanding this molecular mechanism might provide future translational potential and therapeutic interventions for the osteoclast-related pathological bone diseases such as chronic periodontitis, enabling prevention of tooth loss.
