Association of Non-Steroidal Anti-Inflammatory Drugs with Kidney Health in Ambulatory Older Adults

NSAID use in orthopedic surgery: A review of current evidence and clinical practice guidelines

Nonsteroidal anti-inflammatory drugs (NSAIDs) are a valuable class of medications for orthopedic surgeons and often play a pivotal role in pain control. However, there are many common stipulations resulting in avoidance of its use in the treatment of musculoskeletal disease. This review summarizes the mechanism of action of NSAIDs as well as provides an overview of commonly used NSAIDs and the differences between them. It provides a concise summary on the osseous effects of NSAIDs with regard to bone healing and heterotopic ossification. Most of all, it serves as a guide or reference for orthopedic providers when counseling patients on the risks and benefits of NSAID use, as it addresses the common stipulations encountered: "It irritates my stomach," "I have a history of bariatric surgery," "I'm already on a blood thinner," "I've had a heart attack," and "I've got kidney problems" and synthesizes both current research and society recommendations regarding safe use and avoidance of NSAIDs.

NSAID: Current limits to prescription

Non-steroidal anti-inflammatory drugs (NSAIDs) are commonly prescribed to alleviate pain and inflammation in conditions like arthritis, migraines, and post-operative recovery. Their mechanism involves inhibiting prostaglandins that contribute to inflammation. NSAIDs are categorized based on their structure, selectivity for COX-1 and COX-2 enzymes, and plasma half-life. They are effective in treating osteoarthritis, spondyloarthritis, and rheumatoid arthritis but might carry an elevated risk of adverse events. Despite their effectiveness, NSAIDs have limitations and risks that warrant cautious consideration. Extensive research has investigated their side effects, and this review aims to examine the current limitations of oral NSAID therapy, including safety profiles, specific scenarios where their use may not be appropriate, and gaps in knowledge. By critically evaluating these aspects, healthcare practitioners can make informed decisions about prescribing NSAIDs, optimizing patient outcomes while minimizing potential risks. This narrative review summarizes existing knowledge and underscores the importance of risk-benefit assessments in NSAID prescribing. Ultimately, the goal is to enhance the rational use of NSAIDs, maximizing benefits while mitigating adverse effects.

Linalool prevents kidney damage by inhibiting rifampicin-induced oxidative stress and apoptosis

Today, kidney diseases are increasing day by day and life quality is decreasing. In hospitalized patients of all ages, acute kidney injury (AKI) is commonly observed and associated with high rates of morbidity and mortality. Rifampicin (RF) or rifampin is an antibiotic drug from the rifamycin group with a bactericidal effect. RF causes acute kidney injury, often anemia, thrombocytopenia, liver damage and side effect such as cell death. RF causes tissue damage by means of oxidative stress and apoptosis. Thus, in this study, it was examined whether linalool (LN) which had antinociceptive, antimicrobial, antioxidant and anti-inflammatory effects, was beneficial for kidney damage in order to eliminate the side effects of RF. NGAL mRNA, creatinine (Cr), blood urea nitrogen (BUN), Caspase 9 (CAS-9) and nuclear factor-κB (NF-κB) levels increased in the group treated with RF compared to the control group, while the levels of albumin, uric acid and total protein were decreased in the RF-treated group. NGAL mRNA, BUN, Cr, CAS-9 and NF-κB levels decreased significantly in RF+LN administered rats, while it was observed that there was an increase in the levels of albumin, uric acid and total protein. From the results obtained, it was observed that LN was determined to be very effective in preventing tissue damage in kidneys caused by oxidative stress by RF.

Hydroxytriazenes incorporating sulphonamide derivatives: evaluation of antidiabetic, antioxidant, anti-inflammatory activities, and computational study

The existent investigation deals with synthesis, characterization, computational analysis, and biological activities of some hydroxytriazene derivatives containing sulphonamide moiety. The compounds were screened for antidiabetic, antioxidant, and anti-inflammatory activities. The antidiabetic activity was assessed using α-glucosidase and α-amylase inhibition assays with IC₅₀ values ranging from 32.0 to 759.13 μg/mL and 157.77 to 340.47 μg/mL while standard drug acarbose showed IC₅₀ values 12.21 and 69.74 μg/mL, respectively. The antioxidant activity was evaluated using DPPH and ABTS radical scavenging assays with IC₅₀ value ranging from 54.01 to 912.66 μg/mL and 33.22 to 128.11 μg/mL, and standard drug ascorbic acid showed IC₅₀ values 29.12 μg/mL and 69.13 μg/mL, respectively. Anti-inflammatory activity was investigated using the carrageenan-induced paw edema method, where percentage inhibition was up to 93.0 and 98.57 for 2 h and 4 h, respectively, and all the compounds were found to exhibit excellent anti-inflammatory activity. Moreover, prediction of activity spectra for substance and molecular docking were also performed. The PASS prediction hypothesized the potential of the compounds for anti-inflammatory activity, and docking results suggested the best binding pose for compounds 1b and 2b with the least energy value from which compounds can be considered as potent COX-2 inhibitors. Furthermore, possible interactions between hydroxytriazene analogues and the targets of antioxidant NADPH oxidase and antidiabetic human maltase-glucoamylase enzyme have been identified. The HOMO and LUMO analysis revealed charge transfer within the compounds. These findings suggested that the synthesized compounds can be potential agents for the treatment of diabetes and inflammation.

Aspartate aminotransferase/alanine aminotransferase ratio was associated with type 2 diabetic peripheral neuropathy in a Chinese population: A cross-sectional study

OBJECTIVE

Despite previous research that focused on aspartate aminotransferase/alanine aminotransferase ratio (AAR) as predictors of type 2 diabetes mellitus (T2DM) and cardiovascular disease, there has been limited research evaluating the association between AAR and diabetic microvascular complications. This study aimed to investigate the association of AAR with diabetic peripheral neuropathy (DPN).

METHODS

A total of 1562 hospitalized patients with T2DM were divided into four groups according to AAR quartiles. The relationship between AAR and DPN and related parameters was explored by the Spearman correlation coefficients, multivariable logistic regression analysis, and receiver operating characteristic (ROC) curves.

RESULTS

Patients with higher AAR quartiles had higher levels of vibration perception threshold (VPT) and presence of DPN, and AAR was positively associated with VPT and presence of DPN independent of sex, age, body mass index, and diabetic duration (P<0.01 or P<0.05). Moreover, AAR remained significantly associated with a higher odds ratio (OR) of DPN (OR 2.413, 95% confidence interval [CI] 1.081-5.386, P<0.05) after multivariate adjustment. Additionally, the risk of presence of DPN increased progressively as AAR quartiles increased (all P for trend <0.01) in both male and female subjects, and the highest quartile of AAR of male and female subjects was respectively associated with 107.3% (95% CI: 1.386-3.101; P<0.01) and 136.8% (95% CI: 1.550-3.618; P<0.01) increased odds of DPN compared with the lower quartiles. Last, the analysis of receiver operating characteristic curves revealed that the best cutoff values for AAR to predict the presence of DPN were 0.906 (sensitivity: 70.3%; specificity: 49.2%; and area under the curve [AUC]: 0.618) and 1.402 (sensitivity: 38%; specificity: 81.9%; and AUC: 0.600) in male and female subjects, respectively.

CONCLUSIONS

These findings suggest that the high AAR may be associated with the presence of DPN in Chinese patients with T2DM, and may be used as an additional indicator of risk of DPN.

Correlation between perioperative parecoxib use and postoperative acute kidney injury in patients undergoing radical mastectomy: a retrospective cohort analysis

Background

Non-steroidal anti-inflammatory drugs (NSAIDs) are among the most widely prescribed drugs worldwide. However, the effect of NSAIDS on postoperative renal function is still unclear. Few studies have assessed the effects of parecoxib on renal function. Our aim is to investigate a correlation between parecoxib and the presence or absence of AKI postoperatively after a breast cancer surgery operation.

Methods

This was a retrospective cohort study that we performed on our hospitalized database. From January 2012 to August 2021, 3542 female patients undergoing radical mastectomy were enrolled, all data including the patients' information and laboratory results were obtained from electronic medical system. The main outcome was the incidence of AKI postoperatively. AKI was defined in accordance with the KDIGO criteria. Study groups were treated with or without parecoxib. Univariable and multivariable logistic regression analyses were performed.

Results

In our study, about 5.76% experienced AKI. The incidence rate of postoperative AKI (3.49%) within 7 days in the parecoxib group was lower than that in the control group (6.00%, P = 0.05). Compared to the control group, the AKI’s incidence was reduced by 49% (OR = 0.46; 95%CI 0.27–0.97) in parecoxib group in multivariable logistic regression analysis. There was a reduction in the incidence of postoperative AKI in other three subgroups: preoperative eGFR < 90 mL/min·1.73/m2 (OR = 0.52; 95%CI 0.27–0.97), blood loss < 1000 ml (OR = 0.48; 95%CI 0.24–0.96) and non-diabetes (OR = 0.51; 95%CI 0.26–0.98).

Conclusions

Parecoxib was associated with incidence of postoperative acute kidney injury.

Toxic nephropathy: Adverse renal effects caused by drugs

This is a brief overview of toxic nephropathy, which is an increasingly recognised problem with the continual introduction of new drugs and novel drug modalities, especially in oncology, and the risks associated with polypharmacy in many patients; although it is important to remember that it may not always be caused by a drug. It is also important to note that several possibly harmful drugs are now available without prescription ('over-the-counter') and can be purchased easily over the internet, including some poorly characterised herbal remedies. Knowing exactly what our patients are taking as medication is not always easy and patients often fail to mention drugs that may not have been prescribed by a doctor or recommended by a pharmacist. Moreover, patients with several comorbidities often require care from more than one doctor in other specialties, which can also lead to drug prescribing in isolation. This article will summarise some key aspects of drug nephrotoxicity and provide a few clinical pointers to consider, bearing in mind that there is rarely any antidote available, and effective treatment relies on early detection, prompt drug withdrawal, and supportive care. This short review is intended only as a primer to highlight some of the more practical aspects of toxic nephropathy; its content is based on a lecture delivered during the 2021 European Congress of Internal Medicine.

Relative risks of adverse events among older adults receiving opioids versus NSAIDs after hospital discharge: A nationwide cohort study

BACKGROUND

Although analgesics are initiated on hospital discharge in millions of adults each year, studies quantifying the risks of opioids and nonsteroidal anti-inflammatory drugs (NSAIDs) among older adults during this transition are limited. We sought to determine the incidence and risk of post-discharge adverse events among older adults with an opioid claim in the week after hospital discharge, compared to those with NSAID claims only.

METHODS AND FINDINGS

We performed a retrospective cohort study using a national sample of Medicare beneficiaries age 65 and older, hospitalized in United States hospitals in 2016. We excluded beneficiaries admitted from or discharged to a facility. We derived a propensity score that included over 100 factors potentially related to the choice of analgesic, including demographics, diagnoses, surgeries, and medication coadministrations. Using 3:1 propensity matching, beneficiaries with an opioid claim in the week after hospital discharge (with or without NSAID claims) were matched to beneficiaries with an NSAID claim only. Primary outcomes included death, healthcare utilization (emergency department [ED] visits and rehospitalization), and a composite of known adverse effects of opioids or NSAIDs (fall/fracture, delirium, nausea/vomiting, complications of slowed colonic motility, acute renal failure, and gastritis/duodenitis) within 30 days of discharge. After propensity matching, there were 13,385 beneficiaries in the opioid cohort and 4,677 in the NSAID cohort (mean age: 74 years, 57% female). Beneficiaries receiving opioids had a higher incidence of death (1.8% versus 1.1%; relative risk [RR] 1.7 [1.3 to 2.3], p < 0.001, number needed to harm [NNH] 125), healthcare utilization (19.0% versus 17.4%; RR 1.1 [1.02 to 1.2], p = 0.02, NNH 59), and any potential adverse effect (25.2% versus 21.3%; RR 1.2 [1.1 to 1.3], p < 0.001, NNH 26), compared to those with an NSAID claim only. Specifically, they had higher relative risk of fall/fracture (4.5% versus 3.4%; RR 1.3 [1.1 to 1.6], p = 0.002), nausea/vomiting (9.2% versus 7.3%; RR 1.3 [1.1 to 1.4], p < 0.001), and slowed colonic motility (8.0% versus 6.2%; RR 1.3 [1.1 to 1.4], p < 0.001). Risks of delirium, acute renal failure, and gastritis/duodenitis did not differ between groups. The main limitation of our study is the observational nature of the data and possibility of residual confounding.

CONCLUSIONS

Older adults filling an opioid prescription in the week after hospital discharge were at higher risk for mortality and other post-discharge adverse outcomes compared to those filling an NSAID prescription only.
