Abstract
Bisphosphonates are widely used for the prevention and treatment of osteoporosis. Nonsteroidal anti-inflammatory drugs (NSAIDs) are also widely used among the older population group at high risk of fractures. NSAIDs have been shown to impact on bone turnover, and a recent reanalysis of a clinical trial of clodronate found that NSAID use at baseline abrogated any effect of clodronate on either bone density (BMD) or fracture risk. To determine whether NSAIDs influence the efficacy of other bisphosphonates, we have reanalyzed our 6-year randomized controlled trial of zoledronate in 2000 osteopenic postmenopausal women. NSAID use was reported at baseline in 38% of the cohort and anytime use was reported by 65%. The evolution of the zoledronate effects on BMD were almost identical whether or not women were using NSAIDs at baseline and were significant in both subgroups at all BMD sites (p < 0.0001). The significant reduction in the risk of fracture in those allocated to zoledronate (p < 0.0001) showed no interaction with baseline use of NSAIDs (p = 0.33) nor with NSAID use at any time during the study (p = 0.28). The odds of fracture were significantly reduced in both NSAID users and nonusers. We conclude that the present analysis provides no support for the suggestion that NSAIDs interfere with the efficacy of potent bisphosphonates in terms of their effects on bone density or fracture. © 2023 The Authors.

Abstract
Nonsteroidal anti-inflammatory drugs (NSAIDs) and glucocorticoids (GCs) are often used to treat articular-skeletal disorders. The extended use of NSAIDs and GCs have adverse effects on bone metabolism, reducing bone quality and impairing fracture healing. In the present study, we used mouse pre-osteoblast cells MC3T3-E1 to demonstrate the effects of diclofenac (DF) and methylprednisolone (MP) on cell proliferation and gene expression. Cells were incubated with three doses of DF or MP: 0.5 µM, 5 µM, and 50 µM. MP decreased cell viability even after 24 h, but DF inhibited cell viability after only seven days of treatment. The cells were lysed after one, two, three, and seven days of treatment, and gene expression was analyzed by reverse transcription and quantitative PCR (RT-qPCR) assays. DF did not significantly affect the expression of the osteogenic marker genes. MP modified the expression of Osx, Runx, and Col1a1. We concluded that MP is a more potent inhibitor of mouse pre-osteoblast differentiation and viability than is DF. Our results suggest that prolonged DF treatment could be less harmful to osteoblasts than MP treatment.

Abstract
BACKGROUND Diclofenac and other NSAIDs are routinely used in the postoperative period. Their effect on fracture healing remains unclear and controversial. OBJECTIVE The primary outcome was to assess the potential cytotoxicity of clinically relevant concentrations of diclofenac on human osteoblasts. DESIGN Laboratory in vitro study. SETTING Institute of Physiology, Zurich, Center for Integrative Human Physiology, University of Zurich. MATERIALS Monolayers of human osteoblasts. INTERVENTIONS Exposure of human osteoblast monolayers to several concentrations of diclofenac, for different periods of time, with and without an artificially induced inflammatory process. MAIN OUTCOME MEASURES Cell count, cell viability, cell proliferation and apoptosis. RESULTS A concentration-mediated, time and exposure dependent cytotoxic effect of diclofenac-mediated apoptosis was observed. Stimulated inflammatory conditions seemed to reduce toxic effects. CONCLUSION Cytotoxic effects of diclofenac are exposure, time and concentration dependent. Simulating aspects of inflammatory conditions seems to increase resistance to diclofenac cytotoxicity, especially in the presence of higher concentration and longer exposure time.

Abstract
Objective.The autoinflammatory bone disorder chronic nonbacterial osteomyelitis (CNO) covers a wide clinical spectrum, ranging from mild self-limited presentations to chronically active or recurrent courses, which are then referred to as chronic recurrent multifocal osteomyelitis (CRMO). Little is known about treatment options and longterm outcomes. We investigated treatment responses and outcomes in children with CNO.Methods.A retrospective chart review was conducted in a tertiary referral center, covering 2004–2015. Disease activity was measured at 0, 3, 6, 12, and 24 months after treatment initiation, and at the last recorded visit.Results.Fifty-six patients with CNO were identified; 44 had multifocal CNO. Fifty percent of patients relapsed after a median of 2.4 years, and as few as 40% remained relapse-free after 5 years. Nonsteroidal antiinflammatory drugs were used as first-line treatment in 55 patients, inducing remission after 3 months in all individuals with relapse rates of 50% after 2 years. Further treatment included corticosteroids (n = 23), tumor necrosis factor-α (TNF-α) inhibitors (n = 7), and bisphosphonates (n = 8). While 47% of patients with CNO relapsed within 1 year after corticosteroid therapy, favorable outcomes were achieved with TNF-α inhibitors or bisphosphonates (pamidronate).Conclusion.CNO is a chronic disease with favorable outcomes within the first year, but high relapse rates in longterm followup. Particularly, patients with CRMO with long-lasting, uncontrolled inflammation were at risk for the development of arthritis. Our findings underscore the importance of a timely diagnosis and treatment initiation. Prospective studies are warranted to establish evidence-based diagnostic and therapeutic approaches to CNO.

Abstract
Nonsteroidal anti-inflammatory drugs (NSAIDs) are commonly used in bone tissue repair treatment for their pharmacological action. The objective of this study was to determine the effect of aspirin, on osteoblast growth, using MG63 cell line as osteoblast model. MTT spectrophotometry results showed that 20, 100, and 1000 μM aspirin doses have an inhibitory effect on growth. Cell cycle analysis revealed that aspirin doses of 100 and 1000 μM arrest the cell cycle in phase GO/G1. Parallel apoptosis/necrosis studies showed no changes in comparison to control cells after treatment with 1 or 10 μM aspirin but a significantly increased percentage of cells in apoptosis at doses of 20, 100, and 1000 μM. We highlight that treatment of osteoblast-like cells with 1000 μM aspirin increased not only the percentage of cells in apoptosis but also the percentage of necrotic cells, which was not observed in aspirin treatments at lower doses.

Abstract
AIM To examine the effects of acetaminophen (paracetamol), a nonsteroidal anti-inflammatory drug (NSAID), on different cellular and functional parameters of the human osteosarcoma cell line MG63. METHODS Flow cytometry was used to study proliferation, antigenic profile, and phagocytic activity, and radioimmunoassay was used to determine osteocalcin synthesis as a cell differentiation marker. RESULTS Short-term treatment with therapeutic doses of paracetamol(5 or 25 μmol/L) reduced cell proliferation, osteocalcin synthesis, and phagocyte activity, and increased the expression of antigens involved in antigen presentation to T lymphocytes (CD80, CD86, HLA-DR). CONCLUSION These findings suggest that paracetamol activates the osteoblast, inducing its immunogenic action to the detriment of its bone formation capacity.

Abstract
INTRODUCTION Non-steroidal anti-inflammatory drug (NSAID) is well known to significantly delay fracture healing. Results from in vitro studies implicate an impairment of osteoblast proliferation due to NSAIDs during the initial stages of healing. We studied whether diclofenac, a non-selective NSAID, also impairs appearance of osteoblasts in vivo during the early phase of healing (at 10 days). MATERIALS AND METHODS Two defects (Ø 1.1 mm) were drilled within distal femurs of 20 male Wistar rats. Ten rats received diclofenac continuously; the other obtained a placebo until sacrificing at 10 days. Osteoblast proliferation was assessed by cell counting using light microscopy, and bone mineral density (BMD) was measured using pQCT. RESULTS Osteoblast counts from the centre of bone defect were significantly reduced in the diclofenac group (median 73.5 +/- 8.4 cells/grid) compared to animals fed with placebo (median 171.5 +/- 13.9 cells/grid). BMD within the defect showed a significant reduction after diclofenac administration (median 111.5 +/- 9.3 mg/cm(3)) compared to the placebo group (median 177 +/- 45.4 mg/cm(3)). CONCLUSION The reduced appearance of osteoblasts in vivo implicates an inhibiting effect of diclofenac on osteoblasts at a very early level of bone healing. The inhibition of proliferation and migration of osteoblasts, or differentiation from progenitor cells, is implicated in the delay of fracture healing after NSAID application.

Abstract
INTRODUCTION Potential adverse effects of nonsteroidal anti-inflammatory drugs (NSAIDs) on bone metabolism and fracture healing are contradictive to their wide application in post-traumatic treatment. Our objective was to investigate changes to periosteal callus formation with respect to NSAID and central analgesic drug application. Our hypothesis was that callus formation is delayed in animals treated with the non-specific NSAID diclofenac. MATERIALS AND METHODS The left tibia of forty male Wistar rats were osteotomized, stabilized with a Kirschner wire, and randomized into four groups of ten animals. Group 1 received a placebo, group 2 received the central analgesic tramadol (20 mg/kg per day) throughout the study, and groups 3 and 4 were treated with sodium diclofenac (5 mg/kg per day). Group 3 received diclofenac for seven days, followed by placebo until sacrifice (short-term), while group 4 animals received diclofenac for the full period (long-term). Animals were sacrificed 21 days after osteotomy. RESULTS Under light microscopy, all osteotomies healed successfully and independently of the drug treatment. Histomorphometry revealed delayed callus maturation in long-term diclofenac treated animals, with significantly higher amounts of cartilage and less bone, particularly in the outermost region of periosteal callus. Short-term NSAID and tramadol application did not significantly alter callus differentiation. CONCLUSION Callus maturation in vivo was impaired after long-term application of diclofenac which corresponds to the in vitro findings of a dose-dependent effect of NSAIDs on osteoblast proliferation.
