Postoperative intravenous parecoxib sodium followed by oral celecoxib post total knee arthroplasty in osteoarthritis patients (PIPFORCE): a multicentre, double-blind, randomised, placebo-controlled trial.

ABSTRACT: OBJECTIVES:To evaluate the morphine-sparing effects of the sequential treatment versus placebo in subjects undergoing total knee arthroplasty (TKA), the effects on pain relief, inflammation control and functional rehabilitation after TKA and safety. DESIGN:Double-blind, pragmatic, randomised, placebo-controlled trial. SETTING:Four tertiary hospitals in China. PARTICIPANTS:246 consecutive patients who underwent elective unilateral TKA because of osteoarthritis (OA). INTERVENTIONS:Patients were randomised 1:1 to the parecoxib/celecoxib group or the control group. The patients in the parecoxib/celecoxib group were supplied sequential treatment with intravenous parecoxib 40?mg (every 12 hours) for the first 3 days after surgery, followed by oral celecoxib 200?mg (every 12 hours) for up to 6 weeks. The patients in the control group were supplied with the corresponding placebo under the same instructions. PRIMARY AND SECONDARY OUTCOME MEASURES:The primary endpoint was the cumulative opioid consumption at 2 weeks post operation (intention-to-treat analysis). Secondary endpoints included the Knee Society Score, patient-reported outcomes and the cumulative opioid consumption. RESULTS:The cumulative opioid consumption at 2 weeks was significantly smaller in the parecoxib/celecoxib group than in the control group (median difference, 57.31 (95% CI 34.66 to 110.33)). The parecoxib/celecoxib group achieving superior Knee Society Scores and EQ-5D scores and greater Visual Analogue Scale score reduction during 6 weeks. Interleukin 6, erythrocyte sedation rate and C-reactive protein levels were reduced at 72?hours, 2 weeks and 4 weeks and prostaglandin E2 levels were reduced at 48?hours and 72?hours in the parecoxib/celecoxib group compared with the placebo group. The occurrence of adverse events (AEs) was significantly lower in the parecoxib/celecoxib group. CONCLUSIONS:The sequential intravenous parecoxib followed by oral celecoxib regimen reduces morphine consumption, achieves better pain control and functional recovery and leads to less AEs than placebo after TKA for OA.

Project description:INTRODUCTION:Total knee arthroplasty (TKA) has been regarded as a most painful orthopaedic surgery. Although many surgeons sequentially use parecoxib and celecoxib as a routine strategy for postoperative pain control after TKA, high quality evidence is still lacking to prove the effect of this sequential regimen, especially at the medium-term follow-up. The purpose of this study, therefore, is to evaluate efficacy and safety of postoperative intravenous parecoxib sodium followed by oral celecoxib in patients with osteoarthritis (OA) undergoing TKA. The hypothesis is that compared to placebo with opioids as rescue treatment, sequential use of parecoxib and celecoxib can achieve less morphine consumption over the postoperative 2?weeks, as well as better pain control, quicker functional recovery in the postoperative 6?weeks and less opioid-related adverse events during the 12-week recovery phase. METHODS AND ANALYSIS:This study is designed as a multicentre, randomised, double-blind, parallel-group and placebo-controlled trial. The target sample size is 246. All participants who meet the study inclusion and exclusion criteria will be randomly assigned in a 1:1 ratio to either the parecoxib/celecoxib group or placebo group. The randomisation and allocation will be study site based. The study will consist of three phases: an initial screening phase; a 6-week double-blind treatment phase; and a 6-week follow-up phase. The primary end point is cumulative opioid consumption during 2?weeks postoperation. Secondary end points consist of the postoperative visual analogue scale score, knee joint function, quality of life, local skin temperature, erythrocyte sedimentation rate, C reactive protein, cytokines and blood coagulation parameters. Safety end points will be monitored too. ETHICS AND DISSEMINATION:Ethics approval for this study has been obtained from the Ethics Committee, Peking Union Medical College Hospital, China (Protocol number: S-572) Study results will be available as published manuscripts and presentations at national and international meetings. TRIAL REGISTRATION NUMBER:NCT02198924.

Project description:Arthrofibrosis is characterized by excessive extracellular matrix (ECM) deposition that results in restricted joint motion after total knee arthroplasty (TKA). Current surgical and pharmacologic treatment options are limited. Therefore, an in vitro model for joint myofibroblastogenesis is valuable to investigate the arthrofibrotic process and identify diagnostic biomarkers and treatment options. In this study, we obtained intraoperative posterior capsule (PC), quadriceps tendon (QT), and suprapatellar pouch (SP) tissue from knees of four patients undergoing primary TKA for osteoarthritis and characterized primary outgrowth cells from these tissues in the absence and presence of transforming growth factor beta 1 (TGFβ1), a pro-myofibroblastic cytokine. Light microscopy of knee outgrowth cells revealed spindle-shaped cells while immunofluorescence (IF) established staining for the fibroblast-specific antigen TE-7 and Vimentin, which are characteristics of fibroblasts. These fibroblasts differentiate readily into myofibroblasts as highlighted by enhanced alpha smooth muscle actin (ACTA2) mRNA and protein expression and increased collagen mRNA (i.e., collagen type 1 (COL1A1) and collagen type 3 (COL3A1)) expression and collagenous matrix deposition in the presence of TGFβ1. Of note, these studies also revealed that knee-derived fibroblasts are more sensitive to TGFβ1-mediated myofibroblastogenesis than adipose-derived mesenchymal stem cells. Importantly, while outgrowth fibroblasts isolated from four patients and three anatomical regions exhibit similar gene expression profiles, these knee fibroblasts form a unique gene expression cluster within the fibroblast niche as revealed by RNA-sequencing analysis. In conclusion, our study provides a fibroblast/myofibroblast model of outgrowth knee cells derived from patients undergoing primary TKA that can be employed to assess myofibroblast-related processes and test novel pharmacological strategies in vitro for arthrofibrosis.

Project description:ObjectivesTo compare the efficacy and safety of chondroitin sulfate plus glucosamine hydrochloride (CS+GH) versus celecoxib in patients with knee osteoarthritis and severe pain.MethodsDouble-blind Multicentre Osteoarthritis interVEntion trial with SYSADOA (MOVES) conducted in France, Germany, Poland and Spain evaluating treatment with CS+GH versus celecoxib in 606 patients with Kellgren and Lawrence grades 2-3 knee osteoarthritis and moderate-to-severe pain (Western Ontario and McMaster osteoarthritis index (WOMAC) score ?301; 0-500 scale). Patients were randomised to receive 400 mg CS plus 500 mg GH three times a day or 200 mg celecoxib every day for 6 months. The primary outcome was the mean decrease in WOMAC pain from baseline to 6 months. Secondary outcomes included WOMAC function and stiffness, visual analogue scale for pain, presence of joint swelling/effusion, rescue medication consumption, Outcome Measures in Rheumatology Clinical Trials and Osteoarthritis Research Society International (OMERACT-OARSI) criteria and EuroQoL-5D.ResultsThe adjusted mean change (95% CI) in WOMAC pain was -185.7 (-200.3 to -171.1) (50.1% decrease) with CS+GH and -186.8 (-201.7 to -171.9) (50.2% decrease) with celecoxib, meeting the non-inferiority margin of -40: -1.11 (-22.0 to 19.8; p=0.92). All sensitivity analyses were consistent with that result. At 6 months, 79.7% of patients in the combination group and 79.2% in the celecoxib group fulfilled OMERACT-OARSI criteria. Both groups elicited a reduction >50% in the presence of joint swelling; a similar reduction was seen for effusion. No differences were observed for the other secondary outcomes. Adverse events were low and similarly distributed between groups.ConclusionsCS+GH has comparable efficacy to celecoxib in reducing pain, stiffness, functional limitation and joint swelling/effusion after 6 months in patients with painful knee osteoarthritis, with a good safety profile.Trial registration numberNCT01425853.

Project description:In osteoarthritis (OA) treatment, although chondroitin sulfate (CS) was found in a number of studies using radiography to have a structure-modifying effect, to date CS use is still under debate. A clinical study using quantitative magnetic resonance imaging (qMRI) is therefore of the utmost importance. Here we report data from a 24-month, randomised, double-blind, double-dummy, controlled, comparative exploratory study of knee OA. The primary endpoint was to determine the effect of CS 1200 mg/day versus celecoxib 200 mg/day on cartilage volume loss (CVL) in the lateral compartment over time as measured by qMRI. Secondary endpoints included assessment of the OA structural changes and signs and symptoms of OA.qMRI was performed at baseline and at 12 and 24 months. CVL, bone marrow lesion size, and synovial thickness were evaluated using qMRI. The primary statistical analysis was carried out on the modified intention-to-treat (mITT) population (n?=?138) using chi-squared, Fisher's exact, Wilcoxon Mann-Whitney, and Student's t tests and analysis of covariance. Analyses were also conducted on the according-to-protocol (ATP; n?=?120) population.In the adjusted mITT analysis, compared with celecoxib treatment, patients treated with CS had a significant reduced CVL at 24 months in the medial compartment (celecoxib -8.1 %?±?4.2, CS -6.3 %?±?3.2; p?=?0.018) and medial condyle (-7.7 %?±?4.7, -5.5 %?±?3.9; p?=?0.008); no significant effect was seen in the lateral compartment. In the ATP population, CS reduced CVL in the medial compartment at 12 months (celecoxib -5.6 %?±?3.0, CS -4.5 %?±?2.6; p?=?0.049) and 24 months (celecoxib -8.4 %?±?4.2, CS -6.6 %?±?3.3; p?=?0.021), and in the medial condyle at 24 months (celocoxib -8.1 %?±?4.7, CS -5.7 %?±?4.0; p?=?0.010). A trend towards a statistically reduced synovial thickness (celecoxib +17.96?±?33.73 mm, CS -0.66?±?22.72 mm; p?=?0.076) in the medial suprapatellar bursa was observed in CS patients. Both groups experienced a marked reduction in the incidence of patients with joint swelling/effusion and in symptoms over time. Data showed similar good safety profiles including cardiovascular adverse events for both drugs.This study demonstrated, for the first time in a 2-year randomised controlled trial using qMRI, the superiority of CS over celecoxib at reducing CVL in knee OA patients.ClinicalTrials.gov NCT01354145 .
