Comparative Risk of Cardiovascular Outcomes Between Topical and Oral Nonselective NSAIDs in Taiwanese Patients With Rheumatoid Arthritis

Risk of cardiovascular diseases and gastrointestinal bleeding is comparable between celecoxib and non-selective non-steroidal anti-inflammatory drugs in patients with ankylosing spondylitis: a nationwide retrospective cohort study

OBJECTIVE

To compare the risk of cardiovascular disease (CVD) and gastrointestinal bleeding (GIB) between celecoxib and non-selective non-steroidal anti-inflammatory drugs (nsNSAIDs) in patients with ankylosing spondylitis (AS).

METHOD

In this nationwide retrospective cohort study using the Korean Health Insurance Review and Assessment database, adult AS patients who received newly prescribed non-steroidal anti-inflammatory drugs (NSAIDs) continuously for ≥ 30 days (celecoxib or nsNSAIDs) between 2013 and 2017 were evaluated. The co-primary outcomes were the occurrence of composite CVD events, including hospitalization for myocardial infarction, ischaemic heart disease, stroke, transient ischaemic attack, heart failure, and coronary revascularization; and composite GIB, including hospitalization for upper and lower GIB. Propensity score (PS) matching was used to correct for baseline differences between the celecoxib- and nsNSAID-treated groups.

RESULTS

We identified 3164 celecoxib-treated and 18924 nsNSAID-treated patients with AS. After 1:1 PS matching, 3047 patients with AS were assigned to each of the celecoxib- and nsNSAID-treated groups. The incidence of composite CVD and GIB was 18.2/1000 person-years and 6.5/1000 person-years in celecoxib-treated and 15.1/1000 person-years and 7.3/1000 person-years in nsNSAID-treated patients, respectively. Compared to the nsNSAID-treated group, the hazard ratios of composite CVD and GIB in the celecoxib-treated group were not significant, with values of 1.17 (p = 0.499) and 0.87 (p = 0.696), respectively. There were no significant differences in the risk of each component of the composite CVD and GIB between the two groups.

CONCLUSION

We did not find significant differences in the risks of CVD and GIB between celecoxib and nsNSAIDs in AS patients.

Acute Pain Management for the Older Adult

Treating older adults with acute pain in the emergency department is complicated. Undertreated pain can lead to delirium and functional decline. Conversely, common analgesics pose risks of serious drug-drug interactions and adverse drug events. In this review, we discuss issues essential to pain management in older adults including (1) assessing pain in the cognitively impaired, (2) review of analgesic medication classes, (3) principles of geriatric pharmacology, and (4) selecting an analgesic for an older adult with acute pain.

Prevalence of prescription medication use that can exacerbate heart failure among US adults with heart failure

INTRODUCTION

Heart failure (HF) affects more than 6 million adults in the United States, contributing to substantial morbidity, mortality, and health care costs. Despite advances in medical care, many medications can exacerbate HF, yet their prevalence of use remains unknown. This study examined the national use of prescription medications that could exacerbate HF in adults with self-reported HF.

METHODS

We analyzed data from US adults with self-reported HF in the National Health and Nutrition Examination Survey (NHANES) from 2011 to March 2020. Medications known to exacerbate HF, identified from HF guidelines, were documented through pill bottle reviews. Weighted estimates were used to calculate prevalence overall and by sex, race and ethnicity, and level of evidence for avoidance. Multivariable logistic regression models calculated adjusted odds ratios (aORs) and 95% confidence intervals (95% CIs) for the use of these high-risk medications by sex and race and ethnicity.

RESULTS

A total of 687 participants, representing 5.2 million U.S. adults with HF after applying sampling weights, were included (mean age, 66.1 [95% CI 64.9, 67.4] years; 50.4% female [95% CI 45.9%, 55.0%]). Overall, 14.5% (95% CI 10.4%, 19.5%; n = 92) of adults with HF were prescribed at least one medication known to exacerbate HF, with the most common being diltiazem, meloxicam, and ibuprofen. Use of these medications was not significantly different by sex nor by race and ethnicity. Of these medications, 21.7% (95% CI 10.7%, 38.8%) had level A evidence warning against use, and 78.3% (95% CI 61.2%, 89.3%) had B level evidence.

CONCLUSION

Over one-seventh of U.S. adults with HF were likely to have been prescribed medications that could exacerbate the condition, underscoring the need to optimize care. Reducing high-risk medication use may mitigate HF exacerbations and improve outcomes in this vulnerable population.

Clinical Practice Guidelines for Topical NSAIDs in the Treatment of Sports Injuries

Topical nonsteroidal anti-inflammatory drugs (NSAIDs) are commonly used to treat sports injuries, but evidence-based medical guidance for their standardized and rational use is lacking. This guideline working group identified clinically important issues, obtained the full opinions of patients and clinical staff, and discussed them with the expert group. Based on evidence from the literature, the "clinical practice guidelines for topical NSAIDs in the treatment of sports injuries" were formulated following the methods and principles of international guidelines. According to these guidelines, 7 clinical concerns were ultimately selected, and 22 recommendations were formed. These included the status, indications, contraindications, efficacy, combined application, use in special populations, adverse reactions, and countermeasures of topical NSAIDs in the treatment of sports injuries. The purpose of these guidelines is to provide evidence-based recommendations for practitioners in the fields of orthopedics, sports medicine, rehabilitation medicine, and sports science, as well as other fields, in the treatment of sports injuries to promote more standardized and rational use of topical NSAIDs.

Insights from pharmacovigilance and pharmacodynamics on cardiovascular safety signals of NSAIDs

Background and Aim

Non-steroidal anti-inflammatory drugs (NSAIDs) are commonly used to treat fever, pain, and inflammation. Concerns regarding their cardiovascular safety have been raised. However, the underlying mechanism behind these events remains unknown. We aim to investigate the cardiovascular safety signals and receptor mechanisms of NSAIDs, employing a comprehensive approach that integrates pharmacovigilance and pharmacodynamics.

Methods

This study utilized a pharmacovigilance-pharmacodynamic approach to evaluate the cardiovascular safety of NSAIDs and explore potential receptor mechanisms involved. Data were analyzed using the OpenVigil 2.1 web application, which grants access to the FDA Adverse Event Reporting System (FAERS) database, in conjunction with the BindingDB database, which provides target information on the pharmacodynamic properties of NSAIDs. Disproportionality analysis employing the Empirical Bayes Geometric Mean (EBGM) and Reporting Odds Ratio (ROR) methods was conducted to identify signals for reporting cardiovascular-related adverse drug events (ADEs) associated with 13 NSAIDs. This analysis encompassed three System Organ Classes (SOCs) associated with the cardiovascular system: blood and lymphatic system disorders, cardiac disorders, and vascular disorders. The primary targets were identified through the receptor-NSAID interaction network. Ordinary least squares (OLS) regression models explored the relationship between pharmacovigilance signals and receptor occupancy rate.

Results

A total of 201,231 reports of cardiovascular-related ADEs were identified among the 13 NSAIDs. Dizziness, anemia, and hypertension were the most frequently reported Preferred Terms (PTs). Overall, nimesulide and parecoxib exhibited the strongest signal strengths of ADEs at SOC levels related to the cardiovascular system. On the other hand, our data presented naproxen and diclofenac as drugs of comparatively low signal strength. Cyclooxygenase-1 (COX-1) and cyclooxygenase-2 (COX-2) were identified as central targets. OLS regression analysis revealed that the normalized occupancy rate for either COX-1 or COX-2 was significantly inversely correlated with the log-transformed signal measures for blood and lymphatic system disorders and vascular disorders, and positively correlated with cardiac disorders and vascular disorders, respectively. This suggests that higher COX-2 receptor occupancy is associated with an increased cardiovascular risk from NSAIDs.

Conclusion

Cardiovascular safety of NSAIDs may depend on pharmacodynamic properties, specifically, the percentage of the occupied cyclooxygenase isoenzymes. More studies are needed to explore these relations and improve the prescription process.

Safety of Oral and Topical Nonsteroidal Anti-Inflammatory Drugs

Nonsteroidal anti-inflammatory drugs (NSAIDs) are frequently used to manage mild to moderate pain. While limited use is appropriate for many patients, there are safety concerns with use in certain patient populations or with long-term use of these agents. Topical NSAIDs may provide analgesic benefits while decreasing the overall risks of adverse effects. This article will review safety information for both oral and topical NSAIDs.

Cardiovascular disease in patients with systemic autoimmune diseases: The relationship between self-perceived risk and actual risk

INTRODUCTION

Autoimmune diseases are known to be associated with an elevated risk of cardiovascular diseases; however, there exists a lack of awareness regarding this increased risk among patients.

OBJECTIVE

This study aimed to assess the prevalence of cardiovascular risk factors and events in various systemic autoimmune diseases, including Systemic Sclerosis (SSc), Systemic Lupus Erythematosus (SLE), Rheumatoid Arthritis (RA), and Sjögren's syndrome (SS), matched by age, sex, and disease duration. Additionally, the study aimed to evaluate the perceived and actual risks of cardiovascular disease among patients.

METHODS

A cross-sectional self-reported survey on the patient's perspective of cardiovascular risk was conducted between January and June 2023. Sociodemographic and clinical data, including disease activity, were collected through medical records and questionnaires. Traditional cardiovascular risk factors and events were assessed, alongside the perceived cardiovascular risk. The SCORE calculation and Charlson Comorbidity Index (CCI) were employed for cardiovascular risk assessment.

RESULTS

Survey responses from 180 patients (45 patients each with SSc, SLE, RA, and SS) with systemic autoimmune diseases revealed that 20% perceived a low risk, 23% perceived neither lower nor higher, and 56% perceived a higher risk of developing cardiovascular diseases in the next ten years. Only 45% agreed that their autoimmune disease could increase the risk of a heart attack, even in the absence of other risk factors, and 46.7% were unaware that NSAIDs pose a cardiovascular risk. An association between cardiovascular risk measured by SCORE, comorbidities, and risk perception was observed in RA, SSc, and SS patients, with no association found in SLE patients (p=0.27). Except for SS patients (p=0.02), no association between CCI and disease activity level was found. Regarding the influence of age, working status, and education in CVD risk perception, an association between CVD risk perception and age was observed (p=0.01), with patients over 40 years exhibiting a higher perception of CVD risk. No differences were found regarding working status (p=0.19) nor education level (p=0.06).

CONCLUSIONS

Patients with SS, RA, and SSc displayed a heightened perception of cardiovascular risk, correlating with their actual risk and preexisting comorbidities. However, patients exhibited unawareness of certain cardiovascular risk behaviors. This underscores the need for tailored education programs on cardiovascular risk for autoimmune disease patients, to be implemented at the time of diagnosis and during follow-up in outpatient clinics.

Natural sporopollenin microcapsules: biological evaluation and application in regulating hepatic toxicity of diclofenac sodium in vivo

Diclofenac sodium (DIC) is a pain reliever and anti-nociceptive medication. Significant limitations of DIC treatment stem from its adverse effects. This study investigates the feasibility of using natural Lycopodium clavatum sporopollenin (LCS) microcapsules loaded with DIC to mitigate the hepatotoxicity associated with DIC treatment. In addition, LCS microcapsules were tracked in the blood, stomach, small intestine, and feces of rats to demonstrate their morphological integrity and uptake behavior. Four groups (6 per group) of adult male albino rats were administered normal saline (control), empty LCS (30 mg kg-1), plain DIC (10 mg kg-1), and DIC-loaded LCS (40 mg kg-1) orally for seven consecutive days. The first comprehensive histological examination of the rat stomach demonstrated the robustness and bioadhesion ability of LCS under severe conditions. The findings suggested that these versatile microcapsules are unlikely to be digested in the gastrointestinal tract (GIT). The administration of DIC-loaded LCS was found to play a potential protective role in regulating DIC-induced substantially increased serum levels of transaminases, alkaline phosphatase, total bilirubin, and pro-inflammatory cytokines. In addition, DIC-loaded LCS restored the antioxidant enzymes, DNA damage, and liver histological architecture abnormalities caused by DIC. Microencapsulation of DIC into pollen-derived biomaterials could be employed as an efficient platform with enough safety coverage on rat liver, pending further clinical studies.

Non-steroidal anti-inflammatory drugs in chronic kidney disease and risk of acute adverse kidney events according to route of administration

BACKGROUND

Topical non-steroidal anti-inflammatory drugs (NSAIDs) have lower risks for cardiovascular disease and gastrointestinal adverse effects compared to oral NSAIDs, but there are little data regarding their kidney risks in chronic kidney disease (CKD). We evaluated the risk of adverse acute kidney outcomes in CKD according to route of NSAID administration.

METHODS

Retrospective cohort study of adults with CKD (eGFR less than 60 ml/min/1.73 m²) who received prescriptions between 2015 and 2017 from a major healthcare cluster in Singapore. The adverse acute kidney outcomes were acute kidney injury (AKI) and need for nephrology specialist consult within 30 days.

RESULTS

Among 6298 adults with CKD (mean age 72.1 ± 13.3 years and eGFR 41.9 ± 12.2 ml/min/1.73 m²), systemic and topical NSAIDs were prescribed in 16.7% and 32.0%, respectively. Incident AKI (any severity), KDIGO Stage 2 or 3 AKI, and need for nephrology specialist consult occurred in 16.7%, 2.6%, and 10.6% of the study cohort, respectively. After adjusting for age, diabetes, recent cardiovascular hospitalization, baseline eGFR, RAAS blocker and diuretic, systemic NSAIDs, and topical NSAIDs, compared with the no-NSAID group, were independently associated with incident AKI [adjusted OR 1.77 (95% CI 1.46-2.15) and 1.38 (1.18-1.63), respectively]. Moderate and severe AKI (adjusted OR 1.68, 95% CI 1.09-2.58, p = 0.02) and need for nephrology consults (adjusted OR 1.41, 95% CI 1.09-1.82, p = 0.008) were also increased in systemic NSAIDs.

CONCLUSION

Among adults with CKD, both systemic and topical NSAIDs were independently associated with acute adverse kidney outcomes.

Multidisciplinary Guidelines for the Rational Use of Topical Non-Steroidal Anti-Inflammatory Drugs for Musculoskeletal Pain (2022)

(1) Background: Topical non-steroidal anti-inflammatory drugs (NSAIDs) are one of the primary drugs for treating musculoskeletal pain. However, there are currently no evidence-based recommendations about drug selection, drug administration, drug interactions, and use in special populations or other pharmacology-related content of such medications. To this end, the Chinese Pharmaceutical Association Hospital Pharmacy Professional Committee developed multidisciplinary guidelines on using topical NSAIDs to treat musculoskeletal pain. (2) Methods: The guidelines development process followed the World Health Organization guideline development handbook, the GRADE methodology, and the statement of Reporting Items for Practice Guidelines in Healthcare. The guideline panel used the Delphi method to identify six clinical questions to be addressed in the guidelines. An independent systematic review team conducted a systematic search and integration of evidence. (3) Results: Based on the balance between the benefits and harms of an intervention, the quality of the evidence, patient preferences and values, and resource utilization, the guideline panel developed 11 recommendations and nine expert consensuses on using topical NSAIDs to treat acute and chronic musculoskeletal pain. (4) Conclusions: Based on the effectiveness and overall safety of topical NSAIDs, we recommend patients with musculoskeletal pain use topical NSAIDs and suggest high-risk patients use topical NSAIDs, such as those with other diseases or receiving other concurrent treatments. The evidenced-based guidelines on topical NSAIDs for musculoskeletal pain incorporated a pharmacist perspective. The guidelines have the potential to facilitate the rational use of topical NSAIDs. The guideline panel will monitor the relevant evidence and update the recommendations accordingly.

Comparison of glucocorticoids and painkiller prescribed days between rheumatoid arthritis patients receiving early and late treatment with a biological agent via a population-based cohort study

Comparison between early biologics treatment and late biologics treatment of rheumatoid arthritis (RA) patients in decreasing prescription days of glucocorticoids and painkillers by using the Taiwan National Health Insurance Research database from January 1, 1997 to December 31, 2013. We defined early use of biologics as biologics prescribed within 2.24 years after the RA diagnosis, and the late use of biologics was defined as those prescribed after 2.24 years of the RA diagnosis. These definitions are based on previous studies defining early arthritis as arthritis within 2 years of diagnosis, while we needed another 3 months for application biologics here in Taiwan, which equals a total of 2.24 years. Among the 821 patients, 410 patients (50%) were classified in the Early group, and the other 411 patients (50%) were classified in the Late group. The use of any of these 3 types of medication, including steroids, disease modifying antirhuematic drugs, and nonsteroid anti-inflammatory drug (NSAID) was changed significantly after biologics treatment. Comparing between before and after biologics treatment, oral medication was significantly tapered (all P < .0001). The results show that men are 1.81 times more likely than women to taper oral glucocorticoids and NSAIDs. Younger age (<45) patients are 1.91 times more likely to taper steroids and NSAIDs than those aged over 65 years old. Both gender and age were found to be independent factors that could decrease days of prescription of both steroids and NSAIDs in early use of biologics agents. This study indicates that younger patients only need short-term (2.53 ± 1.92 years, P = .03) and early treatment with biologics (within 2.24 years of diagnosis of RA), just in order to taper steroids and NSAIDs to less than 50% compared to the steroids and NSAIDs doses before biologics treatment.

Does coprescribing nonsteroidal anti-inflammatory drugs and oral anticoagulants increase the risk of major bleeding, stroke and systemic embolism?

AIMS

To examine the risk of gastrointestinal (GI) bleeding, major bleeding, stroke and systemic embolism associated with prescribing nonsteroidal anti-inflammatory drugs (NSAIDs) to adults receiving oral anticoagulant (OAC) therapy.

METHODS

We conducted a population-based cohort study in adults receiving OAC therapy using linked primary care (Clinical Practice Research Datalink GOLD) and hospital (Hospital Episodes Statistics) electronic health records. We used cause-specific Cox regression models with time-dependent NSAID treatment in a propensity score matched population to estimate the increased risk of GI bleeding, stroke, major bleeding and systemic embolism associated with NSAID use.

RESULTS

The matched cohort contained 3177 patients with OAC therapy alone and 3177 with at least 1 concomitant NSAID prescription. Compared with OAC therapy alone, concomitant prescription of NSAIDs with OACs was associated with increased risk of GI bleeding (hazard ratio [HR] 3.01, 95% confidence interval [CI] 1.63 to 5.55), stroke (HR 2.71, 95% CI 1.48 to 4.96) and major bleeding (HR 2.77, 95% CI 1.84 to 4.19). The association with systemic embolism did not reach statistical significance (HR 3.02, 95% CI 0.82 to 11.07). Sensitivity analyses indicated that the results were robust to changes in exclusion criteria and the choice of potential confounding variables.

CONCLUSION

When OACs are coprescribed with NSAIDs, the risk of adverse bleeding events increases and, simultaneously, the protective effect of OACs to prevent strokes reduces. There is a need for interventions that reduce hazardous prescribing of NSAIDs in people receiving OAC therapy.

Expert consensus of the Chinese Association for the Study of Pain on pain treatment with the transdermal patch

Chronic pain lasting more than 3 mo, or even several years can lead to disability. Treating chronic pain safely and effectively is a critical challenge faced by clinicians. Because administration of analgesics through oral, intravenous or intramuscular routes is not satisfactory, research toward percutaneous delivery has gained interest. The transdermal patch is one such percutaneous delivery system that can deliver drugs through the skin and capillaries at a certain rate to achieve a systemic or local therapeutic effect in the affected area. It has many advantages including ease of administration and hepatic first pass metabolism avoidance as well as controlling drug delivery, which reduces the dose frequency and side effects. If not required, then the patch can be removed from the skin immediately. The scopolamine patch was the first transdermal patch to be approved for the treatment of motion sickness by the Food and Drug Administration in 1979. From then on, the transdermal patch has been widely used to treat many diseases. To date, no guidelines or consensus are available on the use of analgesic drugs through transdermal delivery. The pain branch of the Chinese Medical Association, after meeting and discussing with experts and based on clinical evidence, developed a consensus for promoting and regulating standard use of transdermal patches containing analgesic drugs.

Comprehensive Review of Topical Analgesics for Chronic Pain

PURPOSE OF REVIEW

Topical analgesics are a non-opioid option for the treatment of chronic pain conditions including neuropathic pain, musculoskeletal pain, and osteoarthritis. There are many topical medications available; however their efficacy is variable. This article reviews the various topical analgesics, their mechanisms of action, and their efficacy.

RECENT FINDINGS

Studies have found topical NSAIDs are useful in treating acute musculoskeletal pain syndromes (strains and sprains) and show some efficacy in treating hand and knee osteoarthritis (Derry et al. Cochrane Database Syst Rev 5:CD008609, 2017). Topical capsaicin 8% has been shown to be efficacious in the treatment of postherpetic neuralgia, painful diabetic peripheral neuropathy, and HIV-neuropathy (Derry et al. Cochrane Database Syst Rev 1:CD007393, 2017). Topical lidocaine has been widely studied and found to reduce pain in patients with postherpetic neuralgia (Knezevic et al. Pain Manag 7:537-58, 2017). Although many other topical analgesics are available, there is limited data to support the efficacy of other agents. Topical analgesics are a relatively benign treatment for chronic pain conditions including neuropathic pain, musculoskeletal, and myofascial pain. There is evidence to support the use of topical NSAIDs, high concentration topical capsaicin, and topical lidocaine for various painful conditions.

Short-Course Systemic and Topical Non-Steroidal Anti-Inflammatory Drugs: Impact on Adverse Renal Events in Older Adults with Co-Morbid Disease

BACKGROUND

Prolonged systemic non-steroidal anti-inflammatory drugs (NSAIDs) have been associated with adverse renal outcomes among older adults. However, there is scant data regarding the renal safety of topical and short-course systemic NSAIDs. We aimed to evaluate the risk of acute adverse renal outcomes among older adults prescribed topical and short-term systemic NSAIDs.

METHODS

We conducted a retrospective cohort study of all older adults, age 60 years and above, who received prescriptions between July 2015 and December 2017 from the largest tertiary hospital and a major public primary care institution in Singapore. Data from 6 months before until 30 days after the first prescription were retrieved from electronic medical records. The primary outcome was the incidence of acute kidney injury (serum creatinine increased >26.5 µmol/L or >50% from baseline) and/or hyperkalemia within 30 days. A multi-variate analysis taking into account age, sex, co-morbidities, baseline-estimated glomerular filtration rate and serum potassium, NSAID route of administration, and concurrent renin-angiotensin-aldosterone system blocker and diuretic prescription was performed to evaluate factors associated with the primary outcome.

RESULTS

We identified 12,773 older adults with incident prescriptions: 3982 (31.2%) received short-course systemic NSAIDs, 3784 (29.6%) received topical NSAIDs, and 5007 (39.2%) did not receive any NSAID. Both short-course systemic NSAIDs (adjusted odds ratio [OR] 1.59, 95% confidence interval [CI] 1.41-1.80, p < 0.001) and topical NSAIDs (adjusted OR 1.48, 95% CI 1.31-1.67, p < 0.001), compared with the no-NSAID group, were independently associated with the primary outcome. Among older adults with co-morbid conditions and prescribed NSAIDs, topical NSAIDs had a reduced odds of 30-day incident acute kidney injury and/or hyperkalemia in diabetes mellitus (adjusted OR 0.78, 95% CI 0.65-1.06, p = 0.007), chronic kidney disease (adjusted OR 0.74, 95% CI 0.60-0.90, p = 0.003), and cardiovascular disease (adjusted OR 0.54, 95% CI 0.37-0.79, p < 0.001), compared with short-course systemic NSAIDs.

CONCLUSIONS

NSAIDs increased the risk of acute adverse renal events. Topical NSAIDs, compared with short-course systemic NSAIDs, were associated with a reduced incidence of acute kidney injury and/or hyperkalemia among older adults with additional risk factors.

Pain management in hidradenitis suppurativa and a proposed treatment algorithm

Pain contributes substantially to reduced quality of life in individuals living with hidradenitis suppurativa (HS). Although improved understanding of HS pathogenesis and treatment has resulted in improved evidence-based HS management guidelines, comprehensive pain management guidelines have yet to be developed. Few HS-specific data exist to guide pharmacologic analgesia; however, recognizing HS pain as either acute or chronic and predominantly nociceptive (aching and gnawing pain due to tissue damage) versus neuropathic (burning-type pain due to somatosensory nervous system dysfunction) provides a conceptual framework for applying outside pain management practices to HS management. This article incorporates the best available evidence from the HS and pain literature to propose an HS pain algorithm that integrates psychological, pharmacologic, and complementary and alternative treatment modalities.

Initial analgesic prescriptions for osteoarthritis in the United Kingdom, 2000–2016

Objectives

To examine trends in the initial prescription of commonly-prescribed analgesics and patient- as well as practice-level factors related to their selection in incident OA.

Methods

Patients consulting with incident clinical OA between 2000–2016 were identified within The Health Improvement Network in the United Kingdom (UK) general practice. Excluded were patients who had history of cancer or were prescribed the analgesics of interest within 6 months before diagnosis of OA. Initial analgesic prescription included oral non-selective NSAID, oral selective cyclooxygenase-2 inhibitor, topical NSAID, paracetamol, topical salicylate or oral/transdermal opioid within 1 month after OA diagnosis.

Results

∼44% of patients with incident OA (n = 125 696) were prescribed one of these analgesics. Incidence of oral NSAID prescriptions decreased whereas other analgesic prescriptions, including oral opioid prescriptions, increased (all P-for-trend &lt; 0.001). Patients with a history of gastrointestinal disease were more likely to receive topical NSAIDs, paracetamol or oral/transdermal opioids. Only 38% of patients with history of gastrointestinal disease and 21% of patients without it had co-prescription of gastroprotective agent with oral NSAIDs. Oral/transdermal opioid prescription was higher among the elderly (≥65 years), women, obesity, current smoker, and patients with gastrointestinal, cardiovascular or chronic kidney disease. Prescription of oral opioids increased with social deprivation (P-for-trend &lt; 0.05) and was highest in Scotland, whereas transdermal opioid prescription was highest in Northern Ireland (all P-for-homogeneity-test &lt; 0.05).

Conclusion

The initial prescription pattern of analgesics for OA has changed over time in the UK. Co-prescription of gastroprotective agents with oral NSAIDs remains suboptimal, even among those with prior gastrointestinal disease.

Topical Diclofenac, an Efficacious Treatment for Osteoarthritis: A Narrative Review

Multiple head-to-head trials have demonstrated that topical nonsteroidal anti-inflammatory drugs (NSAIDs), including topical diclofenac, provide at least equivalent analgesia, improvement in physical function, and reduction of stiffness compared with oral NSAIDs in osteoarthritis and have fewer systemic adverse events. While efficacy of topical diclofenac in osteoarthritis is well established, understanding of the time to onset of action, duration of effect, and the minimum effective concentration is limited. Factors likely to influence these parameters include drug penetration and localization. Diclofenac concentrations in the joint tissues are likely to be more relevant than plasma concentrations. However, although diclofenac penetrates and is retained in these "effect compartments" at the site of inflammation and drug activity, no specific minimum effective concentration of diclofenac in plasma or synovial tissue has been identified. Recent evidence suggests that a reduction in inflammatory markers may be a better predictor of efficacy than plasma concentrations. This narrative review explores existing evidence in these areas and identifies the gaps where further research is needed. Based on our findings, topical NSAIDs such as diclofenac should be considered as a guideline-supported, generally well-tolerated, and effective first-line treatment option for knee and hand OA, especially for older patients and those who have comorbid conditions and/or risk factors for various systemic (gastrointestinal, hepatic, renal, or cardiovascular) adverse events associated with oral NSAIDs, particularly at high doses and with long-term use.

Frailty Predicts an Increased Risk of End-Stage Renal Disease with Risk Competition by Mortality among 165,461 Diabetic Kidney Disease Patients

To examine the effect of frailty on diabetic kidney disease patients’ risk of progression to end-stage renal disease (ESRD), mortality, and adverse episodes, as whether frailty modifies their risk of developing ESRD and other adverse outcomes remains unclear. We identified 165,461 DKD patients from the Longitudinal Cohort of Diabetes Patients in Taiwan (n=840,000) between 2004 and 2010, classifying them into those without frailty or with 1, 2 and ≥3 frailty components based on a modified version of FRAIL scale. Using Cox proportional hazard regression analysis, we examined the long-term risk of developing ESRD along with their risk of mortality, supplemented by a competing risk analysis against mortality. Among all participants, 66.2% (n=109,586), 27.2% (n=44,986), 5.9% (n=9,799), and 0.7% (n=1090) patients did not have or had 1, 2, and ≥3 frailty components, respectively. After a 4.1-year follow-up, 4.2% patients developed ESRD and 18.5% died. Cox proportional hazard modeling revealed that patients with 1, 2, and ≥3 frailty components had increased risks of developing ESRD (for 1, 2, and ≥3 components, hazard ratio [HR] 1.13, 1.18, and 1.2, respectively) and mortality (HR 1.25, 1.41, and 1.34, respectively), with. 9% and 16% risk elevations for ESRD and mortality per component increase. Competing risk analysis showed that frailty-induced ESRD risk was attenuated partially by mortality in those with moderate frailty. The receipt of palliative care did not attenuate this risk. Frailty increased the risk of ESRD based on a dose-response relationship among DKD patients with risk competition by mortality.

Cardiovascular safety of non-steroidal anti-inflammatory drugs in chronic inflammatory rheumatic diseases

Rheumatic diseases (RD), such as rheumatoid arthritis, systemic lupus erythematosus, ankylosing spondylitis, psoriatic arthritis, vasculitis, gout are associated with increase in cardiovascular morbidity and mortality. The main causes of increased cardiovascular risk are inflammatory heart and vascular lesions, accelerated progression of atherosclerosis and side effects of drug therapy. Non-steroidal anti-inflammatory drugs (NSAIDs) are widely used in clinical practice and are on the list of the most prescribed medications. It is known that NSAIDs have a negative effect on the cardiovascular system (CVS). However NSAIDs may decrease the intensity of inflammation, which is an independent risk risk factor for CVS pathology. Therefore in patients with RD it is theoretically possible to reduce the severity of cardiovascular side effects when using NSAIDs. The article discusses the issues of NSAID's cardiovascular safety, the molecular mechanisms underlying the negative effect of them on CVS, critically evaluated the results of main studies concerning the cardiovascular safety of NSAIDs in chronic inflammatory diseases.

Both pre-frailty and frailty increase healthcare utilization and adverse health outcomes in patients with type 2 diabetes mellitus

Background

Diabetes mellitus (DM) correlates with accelerated aging and earlier appearance of geriatric phenotypes, including frailty. However, whether pre-frailty or frailty predicts greater healthcare utilization in diabetes patients is unclear.

Methods

From the Longitudinal Cohort of Diabetes Patients in Taiwan (n = 840,000) between 2004 and 2010, we identified 560,795 patients with incident type 2 DM, categorized into patients without frailty, or with 1, 2 (pre-frail) and ≥ 3 frailty components, based on FRAIL scale (Fatigue, Resistance, Ambulation, Illness, and body weight Loss). We examined their long-term mortality, cardiovascular risk, all-cause hospitalization, and intensive care unit (ICU) admission.

Results

Among all participants (56.4 ± 13.8 year-old, 46.1% female, and 84.8% community-dwelling), 77.8% (n = 436,521), 19.2% (n = 107,757), 2.7% (n = 15,101), and 0.3% (n = 1416) patients did not have or had 1, 2 (pre-frail), and ≥ 3 frailty components (frail), respectively, with Fatigue and Illness being the most common components. After 3.14 years of follow-up, 7.8% patients died, whereas 36.6% and 9.1% experienced hospitalization and ICU stay, respectively. Cox proportional hazard modeling discovered that patients with 1, 2 (pre-frail), and ≥ 3 frailty components (frail) had an increased risk of mortality (for 1, 2, and ≥ 3 components, hazard ratio [HR] 1.05, 1.13, and 1.25; 95% confidence interval [CI] 1.02–1.07, 1.08–1.17, and 1.15–1.36, respectively), cardiovascular events (HR 1.05, 1.15, and 1.13; 95% CI 1.02–1.07, 1.1–1.2, and 1.01–1.25, respectively), hospitalization (HR 1.06, 1.16, and 1.25; 95% CI 1.05–1.07, 1.14–1.19, and 1.18–1.33, respectively), and ICU admission (HR 1.05, 1.13, and 1.17; 95% CI 1.03–1.07, 1.08–1.14, and 1.06–1.28, respectively) compared to non-frail ones. Approximately 6–7% risk elevation in mortality and healthcare utilization was noted for every frailty component increase.

Conclusion

Pre-frailty and frailty increased the risk of mortality and cardiovascular events, and entailed greater healthcare utilization in patients with type 2 DM.
