The aim of the current study was to compare changes in serum biomarkers, including inflammatory mediators, signaling molecules, growth factors and markers of bone turnover after a single intravenous infusion of 5 mg zoledronic acid (ZA, a long-acting bisphosphonate; n = 20) or placebo (n = 20) among patients with Modic changes (MC) and chronic low back pain in a randomized controlled design. The MCs were classified into M1, predominating M1, predominating M2, and M2. We measured the serum concentrations of 39 biomarkers at baseline, and one month and one year after treatment. After Benjamini–Hochberg (B–H) correction, we observed significant differences in three biomarkers over one year: Interferon-γ-inducible protein (IP-10) had risen in the ZA group (p = 0.005), whereas alkaline phosphatase (AFOS) and intact procollagen I N-terminal propeptide (iPINP) had significantly decreased in the ZA group, but had not changed in the placebo group (p < 0.001 for both). Change in iPINP correlated with change in the volume of all MC and M1 lesions. ZA downregulated bone turnover markers as expected and, surprisingly, increased the chemokine IP-10 relative to placebo treatment. This adds to our knowledge of the effects of ZA on MC and the biomarkers that signal this process.

Paget’s disease of the bone (PDB) or osteitis deformans is a chronic metabolic bone disorder, characterized by focal increase in bone resorption, followed by a rapid and abnormal bone repair with a disorganized and excessive bone formation, leading to pain, bone deformities and, eventually, fractures. Although the exact etiology of the disease remains controversial, genetic background and environmental factors (viral infections) are typically involved in the complex pathobiology pathways of PDB. The diagnosis of PDB, subsequent classification in disease subtype (monostotic or polyostotic), activity and severity, and complications (fracture, deformities, osteoarthritis, secondary development of tumors, hearing loss, neural compression, high output congestive cardiac failure) are usually made using a sequence of a blood tests (biochemical markers of bone turnover, especially elevated serum alkaline phosphatase) and imaging (x-ray or bone scan). Bisphosphonates are widely used for the management aiming to reduce bone turnover, promote healing of osteolytic lesions and improve bone pain. We report the case of a polyostotic Paget’s disease of bone as an unusual case of low back pain.
