MedicalResearch.com: What is the background for this study?

Response: Non-steroidal anti-inflammatory drugs (NSAIDs) are widely used and have in previous studies been associated with an increased risk of cardiovascular adverse events, such as myocardial infarction and heart failure. Cardiac arrest is the ultimate adverse event; however, no research exists of the association between cardiac arrest and use of NSAIDs, which we aimed to assess in this study.

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: People with back pain are usually told by their health care practitioners to take analgesic medications to relieve their pain. But our previous research published in the BMJ showed that paracetamol does not have a measurable impact on patient’s symptoms. This resulted in recent changes in guidelines’ recommendations. The 2017 National Institute for Health and Care Excellence (NICE) guidelines/UK no longer recommend paracetamol as a stand-alone intervention for back pain.

So now non-steroidal anti-inflammatory drugs (NSAIDs) are recommended as the analgesic of first choice. However, our results show that compared to placebo, commonly used NSAIDs, such as Ibuprofen (e.g. Nurofen) and Diclofenac (e.g. Voltaren), provide only small benefits for people with back pain while increasing the risk of gastrointestinal adverse effects by 2.5 times.

MedicalResearch.com: What are the main findings?

Response: The ductus arteriosus, a fetal blood vessel that limits blood flow through the lungs, normally closes shortly after birth. However, the ductus often remains open in premature infants, leading to patent ductus arteriosus (PDA). Infants with PDA are more likely to die or develop bronchopulmonary dysplasia (BPD), the major chronic lung disease of preterm infants. Nonsteroidal Anti-inflammatory Drug (NSAID) treatment has been shown to close PDAs in preterm infants and NSAID treatment of PDA is common. However, it has never been shown that PDA closure with NSAIDs leads to decreased mortality or improved long-term respiratory outcomes. NSAID closure of PDA has become increasingly controversial in recent years since NSAID treatment has been associated with acute renal injury. Also, these medications are expensive, with the usual three-dose treatment course costing well over $1000 per patient. Due to these controversies, the likelihood of a preterm infant with PDA being treated with NSAIDs varies by clinician and institution and has decreased over time.
Meta-analyses of randomized trials that investigated NSAID (indomethacin and/or ibuprofen) treatment for PDA closure in preterm infants did not show a benefit. However, they were principally designed only to study whether the ductus itself closed following treatment and not to determine if there was an improvement in mortality risk or in respiratory outcomes following NSAID treatment.
Given the difficulty of conducting randomized trials in preterm infants and the urgent need for practicing clinician’s to know whether treatment of PDA in all preterm infants is beneficial, we used a study design that incorporated the naturally occurring practice variation in NSAID treatment for PDA as a mechanism to reduce the risk of biases that are commonly found in non-randomized investigations. This is based on the premise that if NSAID treatment for PDA in preterm infants is truly effective, we should expect to see improved mortality and respiratory outcomes in instances when clinician preference-based NSAID administration rates are higher.

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: There is a significant amount of data to suggest that long-term, regular use of nonsteroidal anti-inflammatory drugs (NSAIDS; examples include aspirin and ibuprofen) are associated with reduced risks of several cancers. Although the data across studies are inconsistent, one such candidate is endometrial cancer, which is the most common gynecologic cancer. There is good evidence that the use of these medications is associated with improved prognosis among patients diagnosed with colon cancer. Despite the importance of inflammation in endometrial cancer progression, very few have examined whether use of NSAIDs is associated with risk of death or recurrence from the disease. The study we published is the first of its kind to examine NSAID use comprehensively and in a study of over 4,000 patients.

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: We know drugs like ibuprofen, called ‘non-steroidal anti-inflammatory drugs’ cause an increase in the risk of heart attacks. These side effects cause very real concerns for the many millions of people who rely on them. They are also the reason why there are no new drugs in this class and why they have been withdrawn (2011) for use as a preventative treatment for colon cancer. Previous research from our group suggests that L-arginine supplements may prevent the cardiovascular side effects caused by these drugs. Our findings here suggest that a particular formulations of ibuprofen, called ibuprofen arginate, which is already available in many parts of the world, can act like an L-arginine supplement and that this could potentially protect the cardiovascular system.

Herston campus The University of Queensland

Medical Research: What is the background for this study?

Dr. Pandeya: Basal cell carcinoma (BCC) is the most common cancer. Although BCC is curable and has low mortality, its high occurrence in the population causes significant healthcare and financial burdens to the community. Hence exploring preventive strategies for this cancer is important in reducing the burden. To date few chemopreventives for BCC have been identified.

In many cancer cells, inflammatory biomarkers such as cyclooxygenase-2 (COX-2) and its product prostaglandin E2 are increased and basal cell carcinoma is no exception. Anti-inflammatory drugs, suppressing COX-2 activity, have been shown to reduce the risk of various cancers including squamous cell carcinoma of the skin, so they also have a potential to prevent BCC. But to date research evidence on the benefit of aspirin and other nonsteroidal anti-inflammatory drugs (NSAIDs) on basal cell carcinoma has been inconsistent. So we reviewed and synthesized all published epidemiological studies on NSAIDs and BCC to combine results and estimate the overall pooled effect.

Medical Research: What are the main findings?

Dr. Pandeya: After thorough evaluation, we identified eleven studies that were relevant and pooling showed a 10% reduction in risk of BCC among those using any kind of NSAIDs. Aspirin and non-aspirin NSAIDs analysed separately suggested a reduced risk of basal cell carcinoma, but were not statistically significant likely due to lack of power. Our research found strongest risk reduction of BCC by the use of NSAIDs among those with either a history of skin cancers or high prevalence of actinic keratosis.

MedicalResearch: What is the background for this study?

Response: This study is a systematic review of all randomised evidence published up to January 2015 on the effectiveness and safety of non-steroidal inflamatory drugs (NSAIDs) used to treat primary dysmenorrhoea (period pain). It includes 80 randomised controlled trials (total 5820 participants), which compare 20 different NSAIDs versus placebo, other NSAIDs or paracetamol.

The review was prepared by researchers from the Cochrane Collaboration, which is a global independent network of contributors (37,000 from more than 130 countries) who gather and summarize the best evidence from research to produce credible, accessible health information that is free from commercial sponsorship and other conflicts of interest.

Medical Research: What is the background for this study? What are the main findings?

Response: Antidepressants and NSAIDs are each thought to increase the risk of abnormal bleeding.  However, previous studies found neither antidepressants nor NSAIDs alone to be associated with an increased risk of intracranial haemorrhage.  Our research found that combined use of NSADIs in antidepressant users showed the increased relative risk of intracranial haemorrhage risk within the initial 30-days of combined use.

NSAIDS May Be Helpful In Bladder Cancer Prevention

James Scheiman, M.D. Professor of Gastroenterology University of Michigan Medical SchoolMedicalResearch.com Interview with:
James Scheiman, M.D.
Professor of Gastroenterology
University of Michigan Medical School

Medical Research: What is the background for this study? What are the main findings?

Dr. Scheiman: Using aspirin or other nsaids to reduce the risk of many cancers has been an active area of investigation. This study demonstrates in an animal model that a commonly used nsaid (naproxen) reduces bladder tumor development, while the concomitant use of an acid blocking drug– which has been shown in many clinical studies to reduce the ulcers and bleeding associated with nsaids in humans – is also effective. Naproxen has been shown to reduce colon polyps and skin cancers in animal models as well, so this broad effect demonstrates a novel strategy to test in clinical trials.

Medical Research: What should clinicians and patients take away from your report?

Dr. Scheiman: The study shows that using two commonly used classes of drugs together (one which, the proton pump inhibitor, can mitigate the adverse GI side effects of the other without affecting the cancer-reducing effect) may have value to reduce the risk of a number of common cancers. This idea needs to be studied in a clinical trial.

NSAIDS After Heart Attack Increase Risk of Bleeding and Further Heart Attacks

MedicalResearch.com: What is the background for this study?

Dr. Olsen: The question addressed in the study was: Do people who have had a myocardial infarction (heart attack) and are who taking drugs (known as antithrombotics) to reduce their risk of further heart attacks have an increased risk of serious bleeding, especially gastrointestinal bleeding, and of further heart attacks if they also take painkillers known as non-steroidal anti-inflammatory drugs (NSAIDs)?

We found that taking NSAIDs, even for periods of under one week (3-4 days for bleeding), was associated with increased risks of both bleeding and of further heart attacks.

Background: People who have suffered a heart attack are prescribed medicines afterwards to reduce their risk of another one. The medicines usually include two ’antithrombotic drugs’ which make platelets in the blood less sticky – the two most commonly used drugs are aspirin and clopidogrel. A side effect of antithrombotic treatment is that the drugs increase bleeding risk.

Non-steroidal anti-inflammatory drugs (NSAIDs) are used to treat pain and inflammation. They are very effective and are among the most widely used drugs in the world. Some NSAIDs can be bought across the counter without a prescription, for example, ibuprofen. NSAIDs have side effects too. All of them increase the risk of bleeding, especially gastro-intestinal bleeding arising from damage (ulcers) caused to the gut lining. Some NSAIDs, for example diclofenac, are also associated with a small increase in the risk of heart attack – this risk matters most for people already at risk of a heart attack. The medical advice is for these patients to avoid NSAIDs and for their doctors to avoid prescribing them if possible.

But pain is a common problem and very distressing for people – so in practice, NSAIDs are used quite often by patients who have had a heart attack. If NSAIDs are to be taken by heart attack patients, then it is important that both they and their doctors know the risks so that they can weigh up the benefits and downsides and make an informed decision.

What this study did: This was a cohort study that included everyone in Denmark aged 30 years or older who had had a first heart attack and who was taking antithrombotic medicines. Using hospital and dispensing registries, we examined patients who had suffered serious bleeding (causing admission to hospital and/or death) or who had another heart attack or cardiac event to see if they had been prescribed NSAIDs or not.

Dr. Olsen: The study findings: In this study of over 60,000 patients in Denmark taking antithrombotic medicines, one third of them had at least one prescription for NSAIDs, commonly ibuprofen or diclofenac, dispensed over a median study time of 3.5 years. In the same period, 8.5% (5,288 patients or 1 in 12 of the study group) had a gastrointestinal bleed (of whom 799 or 15% died) and 30% (18,568; 1 in 3) had a new cardiac event, mostly heart attack. While these events happened to patients who were prescribed NSAIDs and also to patients were not prescribed NSAIDs, we found that the risk of bleeding was doubled when patients were taking NSAIDs compared with not taking them. The risk occurred within 3 days of starting a NSAID. The risk of a cardiac event (mainly heart attack) was increased by 40% when taking NSAIDs compared with not taking them and also occurred within days of starting a NSAID.

In other words, the NSAIDs appeared 1) to increase the bleeding risk already existing with antithrombotics and 2) to diminish the cardiac protection that antithrombotics provided.

Limitations: This is just one study, although it is a big one. It was a ’real-life’ observational study not a randomised controlled clinical trial. More studies are needed to confirm what we have found.

MedicalResearch:  Why is this important information for patients and doctors to know?

Dr. Olsen: NSAIDs were used a lot by the patients in this study – pain is a common problem and can cause great suffering. There has been a tendency to think that short-term use of NSAIDs is safe – our study suggests this in not the case and that even a few days of use is associated with increased risks of both bleeding and cardiac events, mainly heart attacks. People may be happy to take these risks to have relief from pain but it is very important that they aware of the risks and can make an informed decision about taking NSAIDs for pain relief.
