NSAIDs in CKD: Are They Safe?
Baker, M, Perazella, MA
American journal of kidney diseases : the official journal of the National Kidney Foundation. 2020;(4):546-557
Abstract
The management of pain in patients with chronic kidney disease (CKD) is challenging for many reasons. These patients have increased susceptibility to adverse drug effects due to altered drug metabolism and excretion, and there are limited safety data for use in this population despite a high pain burden. Nonsteroidal anti-inflammatory drugs (NSAIDs) have long been regarded as dangerous for use in patients with CKD because of their risk for nephrotoxicity and thus alternative classes of analgesics, including opioids, have become more commonly used for pain control in this population. Given the well-established risks that opioids and other analgesics pose, further characterization of the risk posed by NSAIDs in patients with CKD is warranted. NSAID use has been associated with acute kidney injury, progressive loss of glomerular filtration rate in CKD, electrolyte derangements, and hypervolemia with worsening of heart failure and hypertension. The risk for these nephrotoxicity syndromes is modified by many comorbid conditions, risk factors, and characteristics of use, and in patients with CKD, the risk differs between levels of glomerular filtration rate. In this review, we offer recommendations for the cautious use of NSAIDs in the CKD population after careful consideration of these risk factors on an individualized basis.

Clark, CCT, Ghaedi, E, Arab, A, Pourmasoumi, M, Hadi, A
Diabetes & metabolic syndrome. 2019;(5):2819-2825
Abstract
OBJECTIVE Our objective was to perform a systematic review and meta-analysis on randomized controlled trials (RCTs) assessing the effect of curcumin on serum adiponectin concentration. METHODS We searched PubMed/Medline, Scopus, ISI Web of Science, Cochrane Library, and Google scholar databases up to April 2019. RCTs conducted among human adults studied the effects of curcumin on serum adiponectin concentrations as an outcome variable was included. The weighted mean differences (WMD) and standard deviations (SD) of change in serum adiponectin levels were calculated. The random effects model was used for deriving a summary of mean estimates with their corresponding SDs. RESULTS Out of 313 records, 6 trials that enrolled 652 subjects were included. The pooled results showed that curcumin supplementation significantly increased adiponectin concentrations in comparison with placebo (WMD: 0.82 Hedges' g; 95% confidence interval (CI): 0.33 to 1.30, P˂0.001). Greater effects on adiponectin were observed in trials lasting ≤10 weeks (WMD: 1.05 Hedges' g; 95% CI: 0.64 to 1.45, P˂0.001). CONCLUSION Curcumin significantly improves adiponectin concentrations. However, due to some limitations in this study, further studies are needed to reach a definitive conclusion about the effect of curcumin on the levels of adiponectin.

Phytotherapy research : PTR. 2017;(4):657-662
Abstract
Vitamin E is an important lipid-soluble antioxidant. The aim of the present study was to investigate the effect of curcumin on serum vitamin E levels in subjects with metabolic syndrome (MetS). A total of 120 subjects aged 18-65 years old with MetS were recruited in this study according to the International Diabetic Federation Criteria. Included subjects were randomized into three groups: subjects receiving lecithinized curcumin (1 g/day equivalent to 200-mg pure curcumin per day) for a period of 6 weeks )n = 40), patients receiving unformulated curcumin (1 g/day) for a period of 6 weeks )n = 40) and a control group receiving placebo for the same period (n = 40). Vitamin E was determined in all patients before and after the intervention using high-performance liquid chromatography method. Results showed that curcumin has no improving effect on serum levels of vitamin E (p > 0.05). There were significant differences between pre-trial and post-trial levels of vitamin E/low-density lipoprotein cholesterol ratio (p < 0.05), vitamin E/high-density lipoprotein cholesterol ratio (p < 0.05), vitamin E/total cholesterol ratio (p < 0.01) and vitamin E/triglyceride ratio (p < 0.05) between the three groups of the study. Results of the present study did not suggest any improving effect of curcumin supplementation on serum vitamin E concentrations in subjects with MetS. Copyright © 2017 John Wiley & Sons, Ltd.

Beneficial action of resveratrol: How and why?
Diaz-Gerevini, GT, Repossi, G, Dain, A, Tarres, MC, Das, UN, Eynard, AR
Nutrition (Burbank, Los Angeles County, Calif.). 2016;(2):174-8
Abstract
Flavonoid resveratrol modulates the transcription factor NF-κB; inhibits the cytochrome P450 isoenzyme CYP1 A1; suppresses the expression and activity of cyclooxygenase enzymes; and modulates Fas/Fas-ligand-mediated apoptosis, p53, mammalian target of rapamycin, and cyclins and various phosphodiesterases. This increases the cytosolic cAMP that activates Epac1/CaMKKβ/AMPK/SIRT1/PGC-1α pathway, which in turn facilitates increased oxidation of fatty acids, mitochondrial biogenesis, mitochondrial respiration, and gluconeogenesis. Resveratrol triggers apoptosis of activated T cells and suppresses tumor necrosis factor-α, interluekin-17 (IL-17), and other proinflammatory molecules, and thus is of benefit in autoimmune diseases. In addition, resveratrol inhibits expression of hypoxia-inducible factor-1α and vascular endothelial growth factor, explaining its effective action against cancer. Brain-derived neurotrophic factor (BDNF) that is involved in the pathogenesis of obesity, type 2 diabetes mellitus, and metabolic syndrome is also altered in depression, schizophrenia, bipolar disorder, and autism. We noted that BDNF protects against cytotoxic actions of alloxan, streptozotocin, and benzo(a)pyrene. Resveratrol prevents bisphenol A-induced autism, type 2 diabetes mellitus, and metabolic syndrome, suggesting that it may augment BDNF synthesis and action. We also observed that BDNF levels are low in type 2 diabetes mellitus and that BDNF enhances production of antiinflammatory lipid, lipoxin A4, whose levels are low in diabetes mellitus. Thus, resveratrol may augment production of lipoxin A4. Resveratrol alters gut microbiota and influences stem cell proliferation and differentiation. These pleiotropic actions of resveratrol may explain the multitude of its actions and benefits.

Abstract
Cardiovascular disease (CVD) has been the number one cause of death in the U.S. for 114 of the last 115 years. Risk factors for prostate cancer have primarily mirrored risk proven risk factors for CVD, especially aggressive disease. Obesity, dyslipidemia, glucose intolerance, metabolic syndrome, unhealthy dietary habits or caloric excess, lack of physical activity, and inflammation are just some of these shared risk factors. The evidence also suggests proven CVD preventive measures are identical to prostate cancer preventive measures, especially in regard to aggressive disease. Thus, apart from lifestyle measures that can encourage optimal heart and prostate health there are potentially several dietary supplements that need to be avoided in healthy men because they may also increase the risk of prostate cancer. However, there are also several low-cost, generic, safe in the appropriate individuals, and naturally derived agents that could reduce prostate cancer risk, and these can be discussed and remembered utilizing the acronym S.A.M. (statins, aspirin, and/or metformin).

Puig, L, Strohal, R, Fuiman, J, Pedersen, R, Szumski, A, Koenig, AS, Robertson, D, Drexel, H
The Journal of dermatological treatment. 2014;(6):470-81
Abstract
OBJECTIVE To assess cardiometabolic biomarkers in patients with psoriasis before and after etanercept treatment. METHODS Patients with moderate-to-severe plaque psoriasis were randomized to etanercept 50 mg once or twice weekly, double-blinded. Cardiometabolic biomarkers were assessed at baseline and after 12 weeks of treatment (n = 273). RESULTS At baseline, 42% of patients had metabolic syndrome. Etanercept was not associated with any clinically relevant adverse effects on cardiometabolic biomarkers. In the once-weekly subgroup, significant mean percentage changes from baseline (p < 0.05) were observed for the quantitative insulin-sensitivity check index (QUICKI; -2.2%), apolipoprotein (Apo) A1 (3.2%), Apo B:Apo A1 ratio (-3.5%), leptin (8.6%) and high-sensitivity C-reactive protein (hsCRP) (-65.5%); and in the twice-weekly subgroup for plasma insulin (15.9%), QUICKI (-2.7%), high-density lipoprotein cholesterol (HDL-C; 2.9%), apolipoprotein (Apo) A1 (2.8%), Apo B:Apo A1 (-4.6%) and hsCRP (-74.4%). CONCLUSION Metabolic syndrome was common in these patients with moderate-to-severe psoriasis. Etanercept treatment may provide some potentially favorable modulation of insulin sensitivity, HDL-C, Apo A1 and Apo B:Apo A1 ratio.

Topical therapies in the management of chronic pain.
Stanos, SP, Galluzzi, KE
Postgraduate medicine. 2013;(4 Suppl 1):25-33
Abstract
Chronic pain, whether localized or generalized, is a widespread, often debilitating condition affecting > 25% of adults in the United States. Oral agents are the cornerstone of chronic pain treatment, but their use may be limited in certain patients, particularly the elderly. Topical therapies offer advantages over systemically administered medications, including the requirement of a lower total systemic daily dose for patients to achieve pain relief, site-specific drug delivery, and avoidance of first-pass metabolism, major drug interactions, infections, and systemic side effects. Several types of topical agents have been shown to be useful in the treatment of patients with chronic pain. Both capsaicin and topical diclofenac have been shown to be effective in the treatment of patients with chronic soft-tissue pain. In patients with hand and knee osteoarthritis (OA), the American College of Rheumatology generally recommends oral treatments (acetaminophen, oral nonsteroidal anti-inflammatory drugs [NSAIDs], tramadol, and intra-articular corticosteroids) and topical NSAIDs equally, favoring topical agents only for patients who have pre-existing gastrointestinal risk or are aged ≥ 75 years. Topical NSAIDs have been shown to provide relief superior to that of placebo and comparable to that of oral ibuprofen. Similarly, ketoprofen gel has been shown to be superior to placebo and similar to oral celecoxib in reducing pain in patients with knee OA. Different formulations of topical diclofenac (including the diclofenac hydroxyethyl pyrrolidine patch, diclofenac sodium gel, and diclofenac sodium topical solution 1.5% w/w with dimethyl sulfoxide USP) have been shown to be superior to placebo and comparable to oral diclofenac in the treatment of patients with pain due to knee OA, with a lower incidence of gastrointestinal complaints than with the oral formulation. In patients with neuropathic pain, topical forms of both capsaicin and lidocaine have been shown to be useful in the treatment of postherpetic neuralgia and diabetic peripheral neuropathic pain. Lidocaine has also demonstrated efficacy in relieving patient pain due to complex regional pain syndrome and may be useful in the treatment of patients with neuropathic pain who have cancer, although clinical trial results have not been consistent. Data suggest that topical therapies may offer a safe, well-tolerated, and effective alternative to systemic therapies in the treatment of patients with chronic, localized musculoskeletal and neuropathic pain.
