Differences in cardiovascular safety with non‐steroidal anti‐inflammatory drug therapy—A nationwide study in patients with osteoarthritis

Prostanoids in Cardiac and Vascular Remodeling

Prostanoids are biologically active lipids generated from arachidonic acid by the action of the COX (cyclooxygenase) isozymes. NSAIDs, which reduce the biosynthesis of prostanoids by inhibiting COX activity, are effective anti-inflammatory, antipyretic, and analgesic drugs. However, their use is limited by cardiovascular adverse effects, including myocardial infarction, stroke, hypertension, and heart failure. While it is well established that NSAIDs increase the risk of atherothrombotic events and hypertension by suppressing vasoprotective prostanoids, less is known about the link between NSAIDs and heart failure risk. Current evidence indicates that NSAIDs may increase the risk for heart failure by promoting adverse myocardial and vascular remodeling. Indeed, prostanoids play an important role in modulating structural and functional changes occurring in the myocardium and in the vasculature in response to physiological and pathological stimuli. This review will summarize current knowledge of the role of the different prostanoids in myocardial and vascular remodeling and explore how maladaptive remodeling can be counteracted by targeting specific prostanoids.

What is known about the health effects of non-steroidal anti-inflammatory drug (NSAID) use in marathon and ultraendurance running: a scoping review

This systematic scoping review aimed to understand the extent and scope of evidence on the health risks of non-steroidal anti-inflammatory drug (NSAID) use in marathon and ultraendurance running. NSAIDs are commonly consumed by runners to combat pain and inflammation; however, the health risks of consuming these drugs during marathon and ultrarunning events are currently not fully understood. Four databases (Cochrane Library, PubMed, MEDLINE and SPORTDiscus) were searched to identify articles focusing on running events of 26.2 miles or further, and they must have reported on the health risks of NSAID use. There was no restriction on the study design or the date of publication. Thirty studies were ultimately included: 4 randomised controlled trials, 1 cross-sectional study, 11 retrospective reviews, 4 case reports, 1 non-randomised control trial, and 9 prospective observational studies. The literature showed that potential health concerns of NSAID use could be split into five categories: electrolyte balance and hyponatraemia; acute kidney injury (AKI); gastrointestinal disturbances; oxidative stress, inflammation and muscle damage; other medical concerns. None of these sections had clear statistically significant links with NSAID use in ultraendurance running. However, potential links were shown, especially in AKI and electrolyte balance. This review suggests there is very limited evidence to show that NSAIDs have a negative impact on the health of ultrarunning athletes. Indications from a few non-randomised studies of a possible effect on kidney function need exploring with more high-quality research.

Older Adult-Onset of Inflammatory Bowel Diseases Is Associated With Higher Utilization of Analgesics: A Nationwide Cohort Study

INTRODUCTION

Patients with inflammatory bowel diseases (IBD) commonly require analgesic medications to treat pain, which may be associated with complications. We examined trends of analgesic use according to age at IBD onset.

METHODS

This nationwide cohort study included adults diagnosed with IBD between 1996 and 2021 in Denmark. Patients were stratified according to their age at IBD onset: 18-39 years (young adult), 40-59 years (adult), and older than 60 years (older adult). We examined the proportion of patients who received prescriptions for analgesic medications within 1 year after IBD diagnosis: strong opioids, tramadol, codeine, nonsteroidal anti-inflammatory drugs, and paracetamol. Multivariable logistic regression analysis was performed to examine the association between age at IBD onset and strong opioid prescriptions and the composite of strong opioid/tramadol/codeine prescriptions.

RESULTS

We identified 54,216 adults with IBD. Among them, 25,184 (46.5%) were young adults, 16,106 (29.7%) were adults, and 12,926 (23.8%) were older adults at IBD onset. Older adults most commonly received analgesic prescriptions of every class. Between 1996 and 2021, strong opioid, tramadol, and codeine prescriptions were stable, while paracetamol prescriptions increased and nonsteroidal anti-inflammatory drug prescriptions decreased. After multivariable logistic regression analysis, older adults had higher adjusted odds of receiving strong opioid prescriptions (adjusted odds ratio 1.95, 95% confidence interval 1.77-2.15) and the composite of strong opioid/tramadol/codeine prescriptions (adjusted odds ratio 1.93, 95% confidence interval 1.81-2.06) within 1 year after IBD diagnosis compared with adults.

DISCUSSION

In this nationwide cohort, older adults most commonly received analgesic prescriptions within 1 year after IBD diagnosis. Additional research is needed to examine the etiology and sequelae of increased analgesic prescribing to this demographic.

Effects of Analgesics on Self-Reported Physical Function and Walking Ability in People With Hip or Knee Osteoarthritis: A Systematic Review and Meta-Analysis

OBJECTIVE

Hip and knee osteoarthritis are among the leading causes of global disability, and one of the main aims of the management is to improve physical function. The objective of this review was to investigate the effect of analgesics on physical function (self-reported physical function and walking ability).

METHODS

A systematic review and meta-analysis of the findings were performed. Randomized controlled trials investigating the effect of analgesics on self-reported physical function and walking ability were included. Analgesics were orally administered acetaminophen, nonsteroidal antiinflammatory drugs (NSAIDs), or opioids. Data were pooled in a random-effects model, and the standardized mean difference (SMD) with 95% CI was calculated (SMDs: 0.2-0.4 = small, 0.5-0.7 = medium, and ≥0.8 = large effect sizes). The quality of the evidence was evaluated according to the Grading of Recommendations Assessment, Development, and Evaluation approach.

RESULTS

A total of 1454 studies were identified, of which 33 were included. On self-reported physical function, the results showed low- to moderate-quality evidence for a small beneficial effect of acetaminophen (SMD = -0.13 [95% CI = -0.26 to 0.00]), NSAIDs (SMD = -0.32 [95% CI = -0.37 to -0.27]), or opioids (SMD = -0.20 [95% CI = -0.32 to -0.09]). There was moderate-quality evidence for a small effect of NSAIDs on pain during walking (SMD = -0.34 [95% CI = -0.45 to -0.23]).

CONCLUSION

In people with hip or knee osteoarthritis, there was low- to moderate-quality evidence for small beneficial effects of analgesics on physical function and walking ability.

IMPACT

Analgesics may improve physical function by reducing pain during exercise and walking.

Treating Geriatric Sports Injury Among Pickleball Players: A Narrative Review of an Exercise Craze Among Seniors

The sudden and enormous popularity of pickleball has included a surprising and large contingent of geriatric players. Similar to tennis and badminton, pickleball is a game with a short learning curve that offers low-impact cardiovascular benefits. Unlike tennis, most injuries in pickleball are sustained by older rather than younger players. In fact, pickleball-related injuries increase with increasing age. Such injuries include strains, sprains, joint pain, falls, and fractures. The most affected joints are the wrists, shoulders, knees, and ankles. Clinicians can advise their older pickleball patients on strategies and tips to minimize the risk of injury. This may be particularly important because many older individuals playing pickleball today were previously sedentary. Older people may be attracted to pickleball because it is an inclusive sport with a high socialization factor. Nevertheless, pickleball can deliver an excellent cardiovascular workout and it may be an example of a successful way to promote exercise among older people and those who resist exercise.

Effects of Resveratrol Co-Administration on Celecoxib Disposition and Pharmacokinetics in Healthy Volunteers

The objective of the current study was to investigate the effects of resveratrol (RSV), a natural herbal remedy used as an adjacent anti-inflammatory supplement on, the pharmacokinetics of celecoxib in healthy male volunteers. Twelve healthy human participants were involved in two-period open-labeled trial. Celecoxib (200 mg) was given as a single oral dose under fasting conditions as a control phase. Afterward, RSV (500 mg) commenced as a single oral dose for ten days as a treatment phase. Blood samples were collected during the control and treatment phases and analyzed using the validated High-performance liquid chromatography (HPLC) method. RSV pre-exposure significantly increased the area under the curve (AUC0-24), peak plasma concentration (Cmax), absorption rate constant (ka), and prolongated half-life (t1/2), along with a decrease in elimination rate constant (ke). Meanwhile, the volume of distribution (Vd/F) and apparent total body clearance (CL/F) were significantly decreased for celecoxib. There was no significant change in the time it takes for celecoxib to reach the maximum concentration (tmax) was observed. The obtained results suggested the presence of a beneficial pharmacokinetic interaction between RSV and celecoxib. Consequently, combining resveratrol as an herbal remedy and celecoxib as an anti-inflammatory drug may synergistically reduce inflammation and osteoarthritis with minimal side effects.

Prevalence of Nonsteroidal Antiinflammatory Drugs Prescribed for Osteoarthritis: A Systematic Review and Meta-Analysis of Observational Studies

OBJECTIVE

Our systematic review aimed to investigate the proportion of participants with osteoarthritis who were prescribed nonsteroidal antiinflammatory drugs (NSAIDs) by their health care provider.

METHODS

Electronic databases were searched for observational studies reporting NSAID prescribing to participants with diagnosed osteoarthritis of any region. Risk of bias was assessed using a tool designed for observational studies measuring prevalence. Random and fixed-effects meta-analysis was used. Meta-regression investigated study-level factors associated with prescribing. The overall evidence quality was assessed using Grading of Recommendations Assessment, Development, and Evaluation criteria.

RESULTS

Fifty-one studies were included, published between 1989 and 2022, with 6,494,509 participants. The mean age of participants was 64.7 years (95% confidence interval [95% CI] 62.4, 67.0; n = 34 studies). Most studies were from Europe and Central Asia (n = 23 studies), and North America (n = 12 studies). Most studies were judged to be at low risk of bias (75%). Heterogeneity was eliminated when removing studies with a high risk of bias, to give a pooled estimate of NSAIDs prescribing to participants with osteoarthritis of 43.8% (95% CI 36.8, 51.1; moderate quality of evidence). Meta-regression determined that prescribing was associated with year (decreased prescribing over time; P = 0.05) and geographic region (P = 0.03; higher in Europe and Central Asia and in South Asia than in North America) but not with clinical setting.

CONCLUSION

Data from over 6.4 million participants with osteoarthritis between 1989 and 2022 indicate that NSAID prescribing has decreased over time and that prescribing differs between geographic locations.

Recommendations for the Use of Nonsteroidal Anti-inflammatory Drugs and Cardiovascular Disease Risk: Decades Later, Any New Lessons Learned?

Nonsteroidal anti-inflammatory drugs (NSAIDs) are among the most prescribed pharmacologic therapies worldwide due to their therapeutic analgesic efficacy and relative tolerability. In the past several decades, various cardiovascular (CV) adverse events have emerged regarding both traditional NSAIDs (tNSAIDs) and cyclo-oxygenase 2 (COX-2) selective (coxibs). This review will provide an updated report on the CV risk profile of NSAIDs, focusing on several of the larger clinical trials, meta-analyses, and registry studies. We aim to provide rheumatologists with a framework for NSAID use in the context of rheumatologic chronic pain management. Recent findings: In patients with and without CV diseases, the use of NSAIDs, both tNSAIDs and coxibs, is associated with an increased risk of adverse CV events, myocardial infarction, heart failure, and cerebrovascular events. These CV risks have increased within weeks of coxib use and higher doses of tNSAIDs. The risk of adverse CV events is heterogenous across NSAIDs; naproxen and low-dose ibuprofen appear to have lower increased CV risk among NSAIDs. A variation in CV risk is associated with multiple factors, including NSAID class, COX-2 selectivity, treatment dose and duration, and baseline patient risk. Summary: Many important questions remain regarding the safety of NSAIDs and whether the culmination of research performed could inform us whether specific patient subtypes or NSAID class may have a more favorable profile. tNSAIDs such as naproxen and low-dose ibuprofen may have a lower CV risk profile, while coxibs have a more favorable GI risk profile. In general, any NSAID can be optimized if used at the lowest effective dose for the shortest amount of time, especially among individuals with increased CV risk.

Cyclooxygenase-2 activates EGFR-ERK1/2 pathway via PGE2-mediated ADAM-17 signaling in testosterone-induced benign prostatic hyperplasia

OBJECTIVE AND DESIGN

Prostatic inflammation is the driving force in benign prostatic hyperplasia (BPH). This work investigated the potential modulatory effect of COX-2 inhibition on ADAM-17/EGFR/ERK1/2 axis.

MATERIALS OR SUBJECTS

Adult male Wistar rats were used.

TREATMENT

Celecoxib (10 and 20 mg/kg; i.p.) was injected i.p. daily for three weeks. Testosterone (TST) (3 mg/kg; s.c.) was used to induce BPH.

METHODS

Prostatic inflammation and hyperplasia were assessed by organ weight and histopathology. Inflammatory mediators were measured using ELISA technique. Protein analysis was performed using western blotting and immunohistochemistry. Gene expression analysis was performed using qRT-PCR. Statistical analyses included one-way ANOVA and Tukey's multiple comparison test.

RESULTS

Testosterone-treated rats had a marked increase in COX-2, prostate weight, and index. Moreover, TST-induced COX-2 was inferred from cytoskeletal changes and was attributable to the overexpression of PGE2, NF-κB (p65), and IL-6. COX-2-derived PGE2 increased the activity of ADAM-17, TGF-α, and TNF-α. Consequently, EGFR-ERK1/2 pathway was over-activated, disrupting anti-apoptotic Bcl-2, cyclin D1, and pro-apoptotic Bax. Celecoxib reversed these effects.

CONCLUSION

COX-2 stimulates the ERK1/2 pathway via PGE2-ADAM-17-catalyzed shedding of TGF-α in testosterone-induced BPH. The results indicate a functional correlation between inflammation and hyperplasia in BPH.

Lessons from 20 years with COX-2 inhibitors: Importance of dose-response considerations and fair play in comparative trials

Nonsteroidal anti-inflammatory drugs (NSAIDs) inhibit the enzyme cyclooxygenase (COX), which forms prostaglandins involved in pain and inflammation. COX inhibitors have analgesic and anti-inflammatory effects, but also increase risks for gastrointestinal ulcers, bleeding, and renal and cardiovascular adverse events. Identification of two isoforms of COX, COX-1 and COX-2, led to the development of selective COX-2 inhibitors, which were launched as having fewer gastrointestinal side effects since gastroprotective prostaglandins produced via COX-1 are spared. The balance between COX-1 mediated prothrombotic thromboxane and COX-2 mediated antithrombotic prostacyclin is important for thrombotic risk. An increased risk of suffering myocardial infarction and death with COX-2 inhibitor treatment is well established from clinical trials and observational research. Rofecoxib (Vioxx) was withdrawn from the market for this reason, but the equally COX-2 selective etoricoxib has replaced it in Europe but not in the United States. The "traditional" NSAID diclofenac is as COX-2 selective as celecoxib and increases cardiovascular risk dose dependently. COX inhibitor dosages should be lower in osteoarthritis than in rheumatoid arthritis. Randomized trials comparing COX-2 inhibitors with NSAIDs have exaggerated their gastrointestinal benefits by using maximal NSAID doses regardless of indication, and/or hidden the cardiovascular risk by comparing with COX-2 selective diclofenac instead of low-dose ibuprofen or naproxen. Observational studies show increased cardiovascular risks within weeks of treatment with COX-2 inhibitors and high doses of NSAIDs other than naproxen, which is the safest alternative. COX inhibitors are symptomatic drugs that should be used intermittently at the lowest effective dosage, especially among individuals with an increased cardiovascular risk.

Low-Dose NSAIDs Efficacy in Orthopedic Applications

Non-steroidal anti-inflammatory drugs (NSAIDs) [cyclooxygenase-1 (COX-1) and cyclooxygenase-2 (COX-2) inhibitors] and COXIBs (the COX-2 selective inhibitors) may induce several potentially severe and life-threatening issues especially in elderly patients. The use of low-dose NSAIDs is associated with lower risk of side effects compared to the standard dosage. Low-dose NSAIDs could minimize the side effects of these drugs while maintaining their clinical efficacy and effectiveness. The present study evaluates the effectiveness and safety of low-dose NSAIDs in musculoskeletal applications.

The Patient-Centered Approach in Rheumatologic Painful Diseases: A Narrative Review

A patient-centric approach to pain control represents a paradigm shift in analgesia and one that is both easy to endorse but challenging to execute. As pain mechanisms become increasingly elucidated, the understanding of pain has changed to encompass its complexities. Multiple types and mechanisms of pain have been described, and pain must be seen through the subjective experience of the patient. Earlier descriptions of pain based on intensity are one-dimensional and do not fully encompass the experience of pain. Thus, treating rheumatology patients or any patient in pain requires an understanding of the primary or secondary nature of the pain, underlying conditions, and patient factors such as anxiety, depression, fearfulness, and catastrophizing, all of which can shape and change the nature of the pain. Further, it is important to manage patient expectations concerning chronic pain as complete pain relief may not be possible, but a Patient Acceptable Symptomatic State (PASS) may serve. Functional goals are often more meaningful to patients than pain scores. Pharmacologic therapy for pain must consider side effects as well as analgesia. Patient-centered pain control requires a focus on wellness and disease prevention, personalized care plans, education, support for self-care, and may involve coordination across disciplines to help the patient meet personally meaningful objectives. While patient-centric care has become a buzzword in modern medicine, it is extremely relevant and may be very beneficial to pain patients.

Clinical Efficacy and Safety of Thai Herbal Formulation-6 in the Treatment of Symptomatic Osteoarthritis of the Knee: A Randomized-Controlled Trial

Background

Osteoarthritis of the knee is the most common form of arthritis. Identifying effective and safe herbal formulations that are locally available is viewed as a priority for sustainable development in a region. This study aimed to evaluate the efficacy and safety of Thai herbal formulation-6 (THF-6) in comparison with oral diclofenac in patients with moderate-to-severe osteoarthritis of the knee.

Methods

This randomized, double-blind, active-controlled, noninferiority trial randomly assigned patients with osteoarthritis of the knee to receive either THF-6 or diclofenac for four weeks. The primary outcome measure was the change from baseline in knee pain as measured by a 100 mm visual analog scale (VAS). Secondary outcome measures included knee stiffness, a stair climb test, the Knee Injury and Osteoarthritis Outcome Score, and safety parameters. Outcomes were assessed on a biweekly basis. Modified intention-to-treat (MITT) and perprotocol (PP) analyses were applied.

Results

A total of 200 patients were enrolled of whom 175 (87.5%) were included in the MITT analysis and 153 (76.5%) in the PP analysis. The mean change in VAS pain did not differ between the two groups, and the upper limit of the two-sided 95% confidence interval (CI) for comparison between the two groups was within the prespecified margin of 10 mm for noninferiority (MITT analysis: mean difference = 0.86, 95% CI = -4.39 to 6.10, p=0.748; PP analysis: mean difference = 1.98, 95% CI = -3.61 to 7.56, p=0.486). Significant improvement was observed in all the efficacy parameters in both groups. Dyspepsia was the most common adverse event: 23 patients in the THF-6 group and 28 in the diclofenac group (p=0.417).

Conclusions

THF-6 offers an alternative to oral diclofenac for the short-term treatment of osteoarthritis of the knee. It was shown to be noninferior to oral diclofenac in relieving knee pain. This trial is registered with ChiCTR-IPR-15007213.

[Pain treatment in old age: special features and recommendations]

BACKGROUND

For geriatric patients with chronic pain, a comprehensive well-coordinated pain management is pivotal to ensure the best possible pain relief and to minimize as far as possible preventable negative side effects of treatment.

OBJECTIVE

Description of the difficulties in pain management of geriatric patients with respect to general basic rules that are worth paying attention to and presentation of pharmacological and non-pharmacological treatment options.

METHODS

This article describes the special features of pain management in older patients and gives recommendations on the use of analgesics and potential drug interactions in geriatric patients with organ dysfunction. Furthermore, individual substance groups are described with respect to their use in geriatric patients based on the recent literature.

CONCLUSION

The aim of an individualized pain treatment in older and multimorbid patients is the relief of pain to an appropriate level, preservation of mobility, self-reliance and autonomy of each individual. The ability to participate in social activities as well as improvement in the quality of life need to be the focus of pharmacological and non-pharmacological treatment.

Naproxen in the environment: its occurrence, toxicity to nontarget organisms and biodegradation

This article summarizes the current knowledge about the presence of naproxen in the environment, its toxicity to nontarget organisms and the microbial degradation of this drug. Currently, naproxen has been detected in all types of water, including drinking water and groundwater. The concentrations that have been observed ranged from ng/L to μg/L. These concentrations, although low, may have a negative effect of long-term exposure on nontarget organisms, especially when naproxen is mixed with other drugs. The biological decomposition of naproxen is performed by fungi, algae and bacteria, but the only well-described pathway for its complete degradation is the degradation of naproxen by Bacillus thuringiensis B1(2015b). The key intermediates that appear during the degradation of naproxen by this strain are O-desmethylnaproxen and salicylate. This latter is then cleaved by 1,2-salicylate dioxygenase or is hydroxylated to gentisate or catechol. These intermediates can be cleaved by the appropriate dioxygenases, and the resulting products are incorporated into the central metabolism. KEY POINTS: •High consumption of naproxen is reflected in its presence in the environment. •Prolonged exposure of nontargeted organisms to naproxen can cause adverse effects. •Naproxen biodegradation occurs mainly through desmethylnaproxen as a key intermediate.

Editorial Commentary: The Curious Incident of the Bone in the Soft Tissue: Is Heterotopic Ossification After Hip Arthroscopy an Interesting Finding or Is It a Complication?

Heterotopic ossification (HO) following hip arthroscopy is a common finding. Naproxen and celecoxib have both been found to decrease the incidence of HO. Whether this makes a clinical difference to outcomes is unclear at this time. A critical weighing of risks and benefits with regard to HO prophylaxis is warranted. Although the authors will personally continue to use nonsteroidal anti-inflammatory drugs for HO prophylaxis, it is up to the discerning reader to draw her/his own conclusion.

Ibuprofen Safety at the Golden Anniversary: Are all NSAIDs the Same? A Narrative Review

Ibuprofen first came to market about 50 years ago and rapidly moved to over-the-counter (OTC) sales. In April 2019, the National Agency for the Safety of Medicines and Health Products (ANSM) of France issued a warning for NSAID uses by patients with infectious diseases based on an analysis of 20 years of real-world safety data on ibuprofen and ketoprofen. Nevertheless, ibuprofen remains a mainstay in the analgesic armamentarium and with numerous randomized clinical trials, head-to-head studies, and decades of clinical experience. The authors offer a review of the safety of ibuprofen and how it may differ from other NSAIDs. Ibuprofen is associated with certain well-known gastrointestinal adverse effects that are related to dose and patient population. Among nonsteroidal anti-inflammatory drugs (NSAIDs), ibuprofen has a comparatively low risk of cardiovascular adverse effects. It has been associated with renal and hepatic adverse effects, which appear to depend on dose, concomitant medications, and patient population. The association of ibuprofen with infections is more complex in that it confers risk in some situations but benefits in others, the latter in cystic fibrosis. Emerging interest in the literature is providing evidence of the role of ibuprofen as a possible endocrine disrupter as well as its potential antiproliferative effects for cancer cells. Taken altogether, ibuprofen has a favorable safety profile and is an effective analgesic for many acute and chronic pain conditions, although it-like other NSAIDs-is not without risk. After 50 years, evidence is still emerging about ibuprofen and its unique safety profile among NSAIDs. FUNDING: The Rapid Service Fee was funded by Abbott Established Pharmaceuticals Division (EPD).

OARSI guidelines for the non-surgical management of knee, hip, and polyarticular osteoarthritis

OBJECTIVE

To update and expand upon prior Osteoarthritis Research Society International (OARSI) guidelines by developing patient-focused treatment recommendations for individuals with Knee, Hip, and Polyarticular osteoarthritis (OA) that are derived from expert consensus and based on objective review of high-quality meta-analytic data.

METHODS

We sought evidence for 60 unique interventions. A systematic search of all relevant databases was conducted from inception through July 2018. After abstract and full-text screening by two independent reviewers, eligible studies were matched to PICO questions. Data were extracted and meta-analyses were conducted using RevMan software. Grading of Recommendations Assessment, Development, and Evaluation (GRADE) Evidence Profiles were compiled using the GRADEpro web application. Voting for Core Treatments took place first. Four subsequent voting sessions took place via anonymous online survey, during which Panel members were tasked with voting to produce recommendations for all joint locations and comorbidity classes. We designated non-Core treatments to Level 1A, 1B, 2, 3, 4A, 4B, or 5, based on the percentage of votes in favor, in addition to the strength of the recommendation.

RESULTS

Core Treatments for Knee OA included arthritis education and structured land-based exercise programs with or without dietary weight management. Core Treatments for Hip and Polyarticular OA included arthritis education and structured land-based exercise programs. Topical non-steroidal anti-inflammatory drugs (NSAIDs) were strongly recommended for individuals with Knee OA (Level 1A). For individuals with gastrointestinal comorbidities, COX-2 inhibitors were Level 1B and NSAIDs with proton pump inhibitors Level 2. For individuals with cardiovascular comorbidities or frailty, use of any oral NSAID was not recommended. Intra-articular (IA) corticosteroids, IA hyaluronic acid, and aquatic exercise were Level 1B/Level 2 treatments for Knee OA, dependent upon comorbidity status, but were not recommended for individuals with Hip or Polyarticular OA. The use of Acetaminophen/Paracetamol (APAP) was conditionally not recommended (Level 4A and 4B), and the use of oral and transdermal opioids was strongly not recommended (Level 5). A treatment algorithm was constructed in order to guide clinical decision-making for a variety of patient profiles, using recommended treatments as input for each decision node.

CONCLUSION

These guidelines offer comprehensive and patient-centered treatment profiles for individuals with Knee, Hip, and Polyarticular OA. The treatment algorithm will facilitate individualized treatment decisions regarding the management of OA.
