Sulfamethoxazole also blocks folate metabolism, albeit at a different junction. The most common cause of sudden cardiac death in young people is this genetic condition that causes the heart muscle to grow too thick. Insufficient consumption and/or ingestion of pharmaceutical compounds that block intestinal thiamine transporters responsible for bringing thiamine into the cells, pose a serious health risk that includes death. Finally, we checked with two of the best drug interaction resources available on the web. Maurer agreed that doctors should avoid this particular drug combination, especially since it mainly affects vulnerable seniors. If people you love take multiple medications, this book might save their lives. The authors also implied that sudden death in those patients might be inappropriately attributed to something other than hyperkalemia, such as an underlying cardiovascular disease. Sudden death in these patients is likely to be misattributed to underlying cardiovascular disease, rather than hyperkalemia., Did you catch that last sentence? This fall the Canadian researchers closed the loop on this deadly drug interaction (BMJ, Oct. 30, 2014). We speculate that this association reflects sudden death from co-trimoxazole induced hyperkalemia in a vulnerable group of patients. Get browser notifications for breaking news, live events, and exclusive reporting. The laws of nature no longer hold true. This was by design, as blocking bacterial folate metabolism makes for a potent antibacterial, which also just so happens, makes it a viable chemotherapeutic. Chandler Marrs MS, MA, PhD spent the last dozen years in womens health research with a focus on steroid neuroendocrinology and mental health. Thiamine acts as a catalyst and cofactor to all of the enzymatic reactions that participate in oxidative metabolism yielding ATP (see figure 1) and is absolutely critical for glucose metabolism. The official journal of The Royal Pharmaceutical Society, International Journal of Pharmacy Practice, Journal of Pharmaceutical Health Services Research. Antibiotics arent supposed to cause multi-symptom, chronic illness. Of these, 11 968 people died suddenly and 328 of these died. Clipboard, Search History, and several other advanced features are temporarily unavailable. FOIA official website and that any information you provide is encrypted We found that use of co-trimoxazole was associated with an increased risk of sudden death in older patients taking angiotensin converting enzyme inhibitors or angiotensin receptor blockers. Norfloxacin, which has no known cardiac effects or interactions with spironolactone, was . For each patient, we defined a period of continuous drug use beginning with the first prescription after their 66th birthday and ending with death, discontinuation of treatment, or the end of the study period, whichever occurred first. Learn how your comment data is processed. These findings indicate that intestinal bacteria contribute to folate metabolism and that colonic contents represent a substantial and natural source of folate. ACE inhibitors and ARBs are used a lot. We're empowering you to make wise decisions about your own health, by providing you with essential health information about both medical and alternative treatment options. Thank you for writing this. Im typically somewhat deficient already due to hyperthyroidism and wondered why the sudden increase in symptoms. I had the rapid heart rate, insomnia , indigestion, and the worst still after finishing is my red gums, red and sore tongue. Fralick M, Macdonald EM, Gomes T, Antoniou T, Hollands S, Mamdani MM, Juurlink DN; Canadian Drug Safety and Effectiveness Research Network. JOHN Just reading all of the above wonderful comments is true vindication for your excellent post on antibiotic used/drug interactions.

And the potassium level of patients taking spironolactone is usually monitored by cardiologists to make sure it stays in the appropriate range. This had been only recently and accidently discovered and is clearly not common knowledge. The thickening makes it hard for the heart to pump blood and can cause fast heartbeats. Canadian Institutes of Health Research/Canada, NCI CPTC Antibody Characterization Program. They should only damage bacteria, while leaving eukaryotic cells unscathed, but they damage mitochondria too (of course they do, mitochondria are ancient bacterium Did anyone think that disrupting the process of DNA replication and reproduction in bacteria wouldnt mess up mitochondrial DNA?). Prescriptions disepensed in the community: England 2002-2012. On average, there have been between 6-7 million prescriptions of this drug written annually from 2007-2017, except for in 2015, where almost 12 million prescriptions were written. In this analysis, we excluded patients who received prescriptions for any other antibiotic in the 21 days preceding the index date. The results were not appreciably different from our primary analyses (see web appendix). What it means is that when an older person dies suddenly while taking co-trimoxazole while on a medication like lisinopril or valsartan, no one will figure out why. Antoniou, who is also a clinical epidemiologist at the non-profit Institute for Clinical Evaluative Sciences, was prompted to conduct his research after reading reports of high potassium levels associated with this particular drug interaction. The trimethoprim component of Bactrim binds to a critical enzyme in the metabolism of folate, called dihydrofolate reductase (DFT).

In other words, it was easier and more economically prudent not to question potential problems in the research or the assumptions driving said research than risk losing a useful and lucrative antibiotic. Its already 2015. Nowhere on the death certificate will it say, This patient died because of a drug interaction mistake.. Ciprofloxacin (adjusted OR 1.55, 95% CI 1.02-2.38) and nitrofurantoin (adjusted OR 1.70, 95% CI 1.03-2.79) were also associated with an increased risk of sudden death, although the risk with nitrofurantoin was not apparent in a sensitivity analysis. SH did the statistical analysis. In 2011, his team published their first study[2] demonstrating the risk of hospital admission resulting from hyperkalaemia in elderly patients taking spironolactone alongside trimethoprimsulfamethoxazole. However, many medical professionals are not aware of this effect of trimethoprim, Antoniou adds. Fralick M, et al. I was first diagnosed with severe osteoporosis when I was thirteen years old. "It's been well-known within the heart failure community that while spironolactone is a great drug, management and use of the drug has to be carefully monitored.". Mr. Zekowski is always on top of his game. The researchers examined cases of sudden death in those who received an outpatient prescription for co-trimoxazole, amoxicillin, ciprofloxacin, norfloxacin, or nitrofurantoin within seven days of death. Canadian Drug Safety and Effectiveness Research Network. There also may be an issue of confounding by indication, as we dont have any data on why these individuals were prescribed these antibiotics. Getting the dabigatran (Pradaxa) story right Correcting four common mistakes. All rights reserved, From Healthy to Barely Functioning After Taking Bactrim and Keflex, Thiamine Deficiency Causes Intracellular Potassium Wasting, by potently blocking both thiamine transporters, glucose-6-phosphate dehydrogenase (G6PD) deficiency, Delirium, gait disturbances and other CNS symptoms, Stephens Johnson Syndrome and toxic epidermal necrosis, lining of the skin and mucous membranes blisters and necrolyses, popular angiotensin enzyme inhibitors (ACE), potentially deadly interactions involving hyperkalemia, high potassium levels via its blockage of the sodium channels in the kidneys, The overall importance of these observations, metabolism of the branched chain amino acids, nor are our vitamin synthesis pathways sufficiently distinct from bacteria, large number of gut bacteria in comparison, regulates something called the mTOR receptor, downregulate mTOR and deregulate mitochondrial function. I have tolerated Z-paks following dental surgery, but I keep my fingers crossed when I take it. We were helping patients with effective dose ranges. This is an important question, because sudden death due to hyperkalemia in the pre-hospital setting is likely to be misattributed to intrinsic heart disease, particularly in older patients with existing cardiovascular disease or diabetes.17. Now, we have computers as close as our smart phones. The importance of our findings is underscored by the fact that co-trimoxazole is prescribed to millions of patients taking angiotensin converting enzyme inhibitors or angiotensin receptor blockers. angiotensin converting enzyme inhibitors (ACE-inhibitors) and angiotensin receptor blockers (ARBs). Neither trimethoprim nor sulfamethoxazole alone kill bacteria. The risk was marginally higher at 14 days (adjusted odds ratio 1.54, 1.29 to 1.84). Hormones Matter is run by CRM Health & Fitness, LLC. There are also limitations to this trial that prevent a definitive answer to what we are supposed to do clinically. A few weeks back we published a case story of young man who developed serious cardiac and neurological symptoms after beginning a course of two antibiotics, Bactrim and Keflex. He is very knowledgeable about the law and extremely professional. This study, published in the BMJ last year, included residents of Ontario, Canada, 66 and older and were treated with ACE-inhibitors or ARBs, GeriPal reports. inflammation of the alveoli of the lungs. In this kind of study, researchers would compare the risk of sudden death within seven days of starting co-trimoxazole with the risk in a control period of non co-trimoxazole use in the same patient. PMC Im lying awake as we speak due to these symptoms and stumbled across your article trying to figure out what was wrong. The overall importance of these observations relates to an expanded mechanism of action, whereby bactericidal antibiotics promote complex redox alterations that contribute to cellular damage and death, while also underlining a common evolutionary and developmental linkage between primordial bacteria and mitochondria (56,57). If you read Hormones Matter, like it, please help support it. It included residents of Ontario who were 66 years of age or older and were treated with an ACE-inhibitors or ARBs. Youll laugh, learn and maybe sing along. We identified prescription drug claims by using the Ontario drug benefit database, which includes prescriptions dispensed to all Ontarians aged 65 years or older. Pocket Casts When trimethoprim was originally discovered and yet still, medicine believed that bacteria were somehow entirely separate from the organism in which they resided. Because of my allergies I took a Penicillin test and I reacted. Of course, with each passing year I have become incrementally more cautious with everyone from infants to the elderly in hospitals or in public health settings. The authors have noted in previous work that cotrimoxazole combined with ACE/ARB drugs associated with a sevenfold increase in the risk of hospital admission for elevated potassium levels. Results Of 39 879 sudden deaths, 1027 occurred within seven days of exposure to an antibiotic and were matched to 3733 controls. Your email address will not be published. Ethical approval: This study was approved by the research ethics board of Sunnybrook Health Sciences Centre, Toronto, Ontario. For a more in-depth discussion on this paper, check out the editorial hereor this wonderful post on #NephJC. They noted then that: These findings support the notion of a potentially life-threatening drug interaction between trimethoprim and inhibitors of the renin-angiotensin aldosterone system.. This corresponds to approximately three sudden deaths within 14 days per 1000 co-trimoxazole prescriptions. A significant proportion of sudden deaths in the young are unexplained-no cause is identified either during life or at post-mortem. Before The BMJ 2011; 343:d5228. Over a 17-year period, almost 12,000 people died suddenly -- 349 of them within 14 days after taking either trimethoprim-sulfamethoxazole or another antibiotic. But the trimethoprim not the sulfamethoxazole can also elevate potassium levels and cause an interaction, he says. The finding of a threefold increased risk of death with cotrimoxazole over amoxicillin in older patients taking ACE inhibitors or ARBs teaches us to consider other antibiotics in these patients. weakness or heaviness of the legs. While it is impossible to rule out the Keflex in his sudden illnesses, as this drug too carries potentially serious side effects, or the combination of the two drugs, I would like to focus on Bactrim for this post, and specifically, its anti-folate and anti-thiamine properties. In the 1970s there were no computers for physicians or pharmacists to use to check for dangerous interactions and there were few references available to check out a possible problem. I am just so wary of medications these days. First published on February 2, 2015 / 3:49 PM. Thank you very much for your job . Objective To determine whether the prescription of co-trimoxazole with an angiotensin converting enzyme inhibitor or angiotensin receptor blocker is associated with sudden death. A Deadly Drug Interaction Often Ignored by Doctors and Pharm Joe Graedon is a pharmacologist who has dedicated his career to making drug information understandable to consumers. "Spironolactone is an old drug that's been around for decades, and has shown to greatly impact older adults with advanced heart failure," said Maurer, also a spokesman for the American College of Cardiology. Results Of 39 879 sudden deaths, 1027 occurred within seven days of exposure to an antibiotic and were matched to 3733 controls. These are among the most popular blood pressure drugs in the pharmacy. Nevertheless, folate deficiency is linked to immune system dysfunction, dermatological issues, cardiovascular dysregulation, and neurologic problems, including sensory neuropathies with axonal damage. Its about the approach to treating people with diseases. Thank you for pointing out to your patients and readers that many conditions are better treated by lifestyle changes. No human can possibly remember all the dangerous drug combinations. NHSBA, 2009. Interpretation: All told, folate is integral for healthy cell function and proliferation, mitochondrial respiration and epigenetic regulation. Many people think trimethoprimsulfamethoxazole [co-trimoxazole] is a fairly innocuous drug with not a lot of side effects, says Tony Antoniou, lead author on the study and a pharmacist at St Michaels Hospital in Toronto, Canada. More commonly, thiamine insufficiency is associated with a litany of dysautonomic syndromes, although it is not widely recognized as such. Co-trimoxazole and sudden death in patients receiving inhibitors of renin-angiotensin system: population-based study. When appropriate, it is prudent for clinicians to evaluate alternative antibiotic regimens, consider a decreased duration of treatment, or closely monitor serum potassium levels in this particular patient population. Be careful out there. An official website of the United States government. Ciprofloxacin (which can prolong the QT interval) and nitrofurantoin (which was associated with hyperkalemia in a prior study) were associated with excess sudden-death risks of borderline statistical significance (adjusted ORs, 1.6 and 1.7, respectively). Its down-regulation shifts towards catabolism resulting in muscle wasting. Interpretation: The antibiotic trimethoprim-sulfamethoxazole was associated with an increased risk of sudden death among older patients taking spironolactone. Taken together, however, the combination yields potent bactericidal effects. WHO model list of essential medicines. We have previously shown that the use of trimethoprim-sulfamethoxazole in patients receiving spironolactone increased the risk of hospital admission with hyperkalemia more than 12-fold relative to amoxicillin. What are you thinking? Diabetic patients require special consideration, as many of them are especially prone to high potassium levels. Characteristics of cases and controls. Social connections impact our health in profound ways, whether it, Do we need an RCT to establish the worth of, Two weeks ago on the GeriPal podcast we talked about, Psychedelics are having a moment. Young healthy patients have organ reserve. And the researchers did not know why the individuals had been prescribed the antibiotics.But the results point toward greater caution in prescribing Bactrim to those taking ACE-inhibitors and ARBs, and closer monitoring of potassium levels in those patients. Drug interactions are the Achilles heel of the medical profession. Indeed, bacterial folate synthesis genes are ubiquitous across the gastrointestinal tract, 13% of which, contain all of the required for complete de novo folate synthesis and almost 40% have the genetic capacity to synthesize folates in the presence of PABA, the upstream intermediate blocked by the sulfamethoxazole component of Bactrim. The study authors also found evidence of an interaction between spironolactone and the antibiotic ciprofloxacin (brand names Cetraxal, Cipro), which increased by half a person's risk of sudden death, Antoniou said. We used amoxicillin as the reference exposure because it is not an independent risk factor for hyperkalemia and is not associated with torsades de pointes. This inhibits the reduction of folate into cofactors necessary for DNA synthesis. Ciprofloxacin can prolong the QT interval and cause torsades de pointes in susceptible patients.27 28 35 36 37 Ciprofloxacin induced QT prolongation occurs early in the course of treatment and generally resolves when treatment is stopped;25 37 this may explain why the effect was attenuated in the 14 day analysis. Every drug which works to effect positive change can have potentially disastrous results when poorly selected or administered during a vulnerable period of time for a particular patient. 2009; Lakoff et al. As a structural analog to PABA, sulfamethoxazole binds to and blocks a key enzyme in the folate pathway (dihydropteroate synthetase) thereby inhibiting the conversion of PABA and downstream metabolites critical for folate synthesis and metabolism. Notes on Folate Carriers, Anti-Folate Medications, and Thiamine Deficiency, With Thiamine Paradox Symptoms Patience Is Key. Each case was matched with up to four controls on age, sex, presence of kidney disease, and diabetes. How can it hurt?. Although we had no information on indications for antibiotic use, we used a disease risk index to adjust for potential predictors of sudden death. Thank you for the thoughtful and insightful post! His symptoms immediately reminded me of beriberi induced by an acute thiamine deficiency. 2013. Antibiotic use and risk of sudden death within seven days. My phone calls were always returned quickly and all of my questions were answered in a thorough manner. Its absence or insufficiency thus, derails downstream functions associated the conversion of food into ATP in each of the substrate pathways, glucose, protein, and fats, creating a biological energy deficiency that imperils human health. One warned that potassium levels may increase and therefore should be monitored. No endorsement by ICES or the Ontario MOHLTC is intended or should be inferred. Antoniou T, Gomes T, Mamdani MM, Yao Z, Hellings C, Garg AX, Weir MA, Juurlink DN. DNJ is the guarantor. Of the more than 1.5 million patients included in the study, nearly 40,000 died suddenly after beginning oral antibiotic treatment. Did you also note that the authors said millions of patients receive this antibiotic in combination with ARBs or ACE inhibitors? However, the sudden death of a young nonathlete is no less tragic. The interaction can lead to dangerously high levels of potassium (hyperkalemia) in the body, which in turn can trigger fatal heart rhythm abnormalities. But the researchers did not have any data on serum potassium concentrations. The antibiotic trimethoprim-sulfamethoxazole was associated with an increased risk of sudden death among older patients taking spironolactone. Automated systems check on interactions before a doctor can finalize a prescription and before a pharmacist can dispense it. A few years back, I had a confirmed UTI (P. mirabilis). "We want to make sure pharmacists and physicians are aware of this interaction, but I don't think it's on the radar that this is something that can happen.". We examined whether this drug combination is associated with an increased risk of sudden death, a consequence of severe hyperkalemia. Thank you so much for this information. A standardized difference less than 0.1 indicates good balance between cases and controls for a given covariate.31 We used conditional logistic regression to estimate the odds ratio and 95% confidence interval for the association between sudden death and recent antibiotic use. By binding DHT, dihydrofolic acid (DHF) and then tetrahydrofolic acid (THF) are blocked. This is addition to a spectrum of neuropsychiatric manifestations from depression to dementia that are associated with this critical nutrient. inflammation . We speculate that this association reflects sudden death from co-trimoxazole induced hyperkalemia in a vulnerable group of patients. BMJ. I do not understand why this is not more well known. No one wants to pay much for this kind of preventive care, so you essentially donate your time and energy to do this. It is prescribed for everything from acne and UTIs to prophylactic treatments associated with HIV. An interaction between the commonly prescribed antibiotic co-trimoxazole and blood pressure drugs such as lisinopril or valsartan can cause sudden death. Of the 1,601,542 patients in the study treated with either anACE-inhibitoror ARB, 39,879died suddenly. CastBox We do not capture any email address. Heart rhythm disorders. 2013. The mTOR pathway regulates the balance between protein anabolism and catabolism critical for cell growth and division. In a previous publication by the authors of this study, there was a seven sevenfold increase in the risk of hyperkalemia induced hospital admissions inACE-inhibitors and ARBusers taking trimethoprim-sulfamethoxazole compared with those exposed toother antibiotics. Thiamine is, after all, in most enriched and fortified foods. TA is supported by a new investigator award from the Canadian Institute for Health Research and Ontario HIV Treatment Network. When trimethoprim was present, folate to DFT was not reduced, even when extra folic acid was added to the media. For each case, we randomly selected up to four controls from the same cohort, matched on age (within 1 year), sex, and the presence or absence of kidney disease and diabetes, recognized risk factors for hyperkalemia and sudden death.29 30 Each control could serve as a control only once, although they were eligible to become a case at a later date. From this perspective, it is not inconceivable that a significant portion of the population is thiamine insufficient, if not outright deficient. KEEP UP the GREAT work John!

These efforts are ongoing. So is the QT prolonging potential of Bactrim caused by its ability to promote hyperkalemia? RSS, We invite the brightest minds in geriatrics, hospice, and palliative care to talk about the topics that you care most about, ranging from recently published research in the field to controversies that keep us up at night. Importantly, ciprofloxacin also tends to be used in patients with more severe or complicated urinary tract infections.38 Whether QT prolongation, severity of illness, or different indications explain the risk associated with ciprofloxacin is unclear. it has been demonstrated that major classes of bactericidal antibiotics, irrespective of their drug-target interactions, induce a common oxidative damage cellular death pathway in bacteria, leading to the production of lethal reactive oxygen species (ROS) (412) via disruption of the tricarboxylic acid (TCA) cycle and electron transport chain. Our Firm Brochure Video Vault FAQS Recently In The News Press Releases Locations New York Attorneys Long Island Attorneys MeSH In 2006, Long Island University awarded him an honorary doctorate as one of the country's leading drug experts for the consumer.. Thanks for a great post, and for helping me to feel less like a dinosaur. In Canada, the drug is generally prescribed as trimethoprimsulfamethoxazole, whereas in the UK, trimethoprim is typically prescribed on its own. The trouble is, physicians and pharmacists often ignore and override drug interaction alerts, especially those they deem relatively unimportant. Ciprofloxacin and nitrofurantoin were also associated with an increased risk of death (adjusted OR 1.55, 95% CI 1.02-2.38; and adjusted OR 1.70, 95% CI 1.03-2.79, respectively), although the risk with nitrofurantoin was not apparent in a sensitivity analysis. I am now, In using a fictitious example, the mother of a football playing athlete takes an interest in, Dr. Marrs and I became aware of the symptoms and some of the laboratory results in, Over recent years, a number of new diets have become popular among health conscious individuals. The PubMed wordmark and PubMed logo are registered trademarks of the U.S. Department of Health and Human Services (HHS). During the 17 year study period, we identified 1 601 542 patients treated with either an angiotensin converting enzyme inhibitor or angiotensin receptor blocker. These databases are routinely used to conduct population based studies of drug safety, including the consequences of drug-drug interactions.6 7 14 24 We linked them in an anonymous fashion by using encrypted health card numbers.
