The Effect of NSAID on Serum Periostin

Low back pain (LBP) is one of the most prevalent musculoskeletal disorders worldwide and constitutes a major source of disability and socioeconomic burden. Intervertebral disc degeneration (IVDD) is recognized as one of the primary etiological contributors to LBP, and its prevalence increases substantially with age. The intervertebral disc (IVD) is a complex fibrocartilaginous structure composed of a central gelatinous nucleus pulposus (NP), a surrounding annulus fibrosus (AF), and superior and inferior cartilaginous endplates. The NP and AF cells synthesize a water-rich extracellular matrix (ECM) that confers the disc with its biomechanical properties, enabling load distribution and flexibility of the spinal column. Under physiological conditions, ECM homeostasis within the IVD is tightly regulated; however, various intrinsic and extrinsic stimuli can disrupt this balance and initiate the degenerative cascade. IVDD has been attributed to a multitude of factors, including aging, obesity, genetic predisposition, mechanical overload, degeneration of the multifidus and psoas muscles, osteoporosis, oxidative stress, and chronic low-grade inflammation. Dysfunction of NP and AF cells, compounded by excessive endplate metabolic activity, leads to progressive endplate calcification, loss of disc hydration, structural failure of the AF, and ultimately irreversible IVDD. Among these contributing factors, elevated oxidative stress and increased secretion of pro-inflammatory cytokines-s…
