HHS Vulnerability Disclosure, Help 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. Results Of 39 879 sudden deaths, 1027 occurred within seven days of exposure to an antibiotic and were matched to 3733 controls. "We wanted to see if this translated into a higher risk for sudden death in these patients," he said. Introduction. Go ahead and just cover him with some Bactrim. We included ciprofloxacin because of its clinical popularity, although it is typically used for more complicated infections and can predispose to sudden death by prolonging the QT interval.26 27 28 We excluded patients who received prescriptions for any other antibiotic in the 14 days preceding the index date, thereby restricting the analysis to patients with only one antibiotic prescription. Tradeoffs are truth. Antibiotic use and risk of sudden death within seven days. First published on February 2, 2015 / 3:49 PM. Careers. These findings indicate that intestinal bacteria contribute to folate metabolism and that colonic contents represent a substantial and natural source of folate. Unfortunately I suspect readers of your column like me are part of the choir so the task that remains is to convey these important messages to our non-choir colleagues in the medical community. 2015; Rossi et al. 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?). Please note: your email address is provided to the journal, which may use this information for marketing purposes. With more than 250 million prescriptions for ACE inhibitors and ARBs annually, and more than 20 million prescriptions for trimethoprim/sulfamethoxazole dispensed each year in the United States, chances are that the 2 will be prescribed together. We excluded cases that could not be matched to at least one control. I will be more in tune and reading your blog for sure. The cases were those who had sudden death and who received an outpatient prescription for either co-trimoxazole, amoxicillin, ciprofloxacin, norfloxacin, or nitrofurantoin within 7 days of death. 2014 Oct 30;349:g6196. The cause of death will likely be assumed to be of "natural causes" such as a heart attack. technical support for your product directly (links go to external sites): Thank you for your interest in spreading the word about The BMJ. We obtained physicians claims data from the Ontario health insurance plan database and identified patients with diabetes by using the Ontario diabetes database.21 We used the Ontario congestive heart failure database to identify people with heart failure.22 We identified sudden death from the vital statistics database, which contains the cause of death listed on individual death certificates.23 In Ontario, all death certificates are completed by the physician who last provided care to the patient, the patients family physician, or a coroner. The answer to that question has to do in part to shoddy research and in part to an economically self-serving framework for understanding human physiology that has since become institutionalized into medical dogma. We used SAS version 9.3 for all analyses and a two sided type 1 error rate of 0.05 as the threshold for statistical significance. These really should come as no surprise, but again and again they do. weight gain or loss. ACE inhibitors and ARBs are used a lot. Everyone I have dealt with at your firm has been very professional and courteous. Years later I was giving Cipro.With Cipro I had Ulnar nerve entrapment and muscle atrophy. They come with tradeoffs, and, the more drugs we use together in a patient, the more tradeoffs we should expect. The decreased risk for the seven day analysis may be spurious, given the relatively small sample size, and may reflect selection of patients, as nitrofurantoin is generally reserved for uncomplicated urinary tract infections. "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.". And be honest; did you know trimethoprim blocks the epithelial sodium channel (ENaC) in the distal nephron, thereby impairing potassium elimination? TORONTO, ON The risk of sudden death went up by more than a third in older patients taking ACE inhibitors or angiotensin-receptor blockers (ARBs) who were also put on the antibacterial agent. Clinical trials, case reports, and laboratory studies show that co-trimoxazole induced hyperkalemia can occur quickly and can cause life threatening arrhythmias, especially among patients receiving angiotensin converting enzyme inhibitors or angiotensin receptor blockers.13 15 16 19 33 34 Our previous research on this drug interaction showed a nearly sevenfold increased risk of hospital admission with hyperkalemia following co-trimoxazole treatment but no such risk with the same alternative antibiotics studied here.14 In the analysis presented here, we found no increased risk of sudden death with nitrofurantoin or norfloxacin. When appropriate, alternative antibiotics should be considered in such patients. The results were not appreciably different from our primary analyses (see web appendix). KEEP UP the GREAT work John! In reality, however, there are a number of serious side effects associated with it including: A review published in 2011, identified 925 papers on the adverse effects of trimethoprim and sulfamethoxazole through 2011. Considering that the vast number of medication adverse reactions are rarely identified much less published, almost 1000 papers published suggests something is going on with this medication. Because trimethoprim induced hyperkalemia may take longer to manifest clinically, we replicated our analyses using a 14 day period between antibiotic prescription and sudden death. Of these deaths, 1,110 occurred within seven days of a prescription for one of the study antibiotics, GeriPal reports. That is, how are Bactrim and other thiamine depleting drugs capable of provoking such a rapid decline into fulminant deficiency? 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. Podcast Addict (Those stakeholders are getting pissed I mean, dont trust computers? 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. Diabetic patients require special consideration, as many of them are especially prone to high potassium levels. The primary efficacy outcome was the time to the first event of the primary composite endpoint, which consisted of cardiovascular death, resuscitated sudden death, non-fatal myocardial. Within this group, we identified cases as patients who died of sudden death within 14 days after receiving a prescription for trimethoprim-sulfamethoxazole or one of the other study antibiotics (amoxicillin, ciprofloxacin, norfloxacin or nitrofurantoin). 1996; Magnusdottir et al. However, this applies equally to all the antibiotics we studied. Nevertheless, it was well known that Bactrim blocked folate, that folate was critical to human health, and that its deficiency could wreak havoc on health. MMM and DNJ obtained funding. Thank you. With the exception of co-trimoxazole, none of these is an independent risk factor for severe hyperkalemia. UTIs are one of the most common types of infections; at least one in two women and one in 10 men will experience a UTI in their lifetime. The risk was marginally higher at 14 days (adjusted odds ratio 1.54, 1.29 to 1.84). If ones diet is high in sugars, supplemented with coffee or tea, and/or if alcohol is consumed regularly, the path to thiamine deficiency is expedited. The researchers caution that limitations to this trial prevent a definitive answer. and transmitted securely. It has been shown that specific transporters in the colon actively absorb folate (Said 2013) and as such contribute to folate levels in peripheral tissues and the circulation (Aufreiter et al.

Its a good post about another antibiotic to avoid and I appreciate the warning. Canadian Drug Safety and Effectiveness Research Network. We used administrative data and did not have access to serum potassium or creatinine concentrations, adherence to treatment, non-prescription drug use, and other risk factors for sudden death. Most of the patients who died were. We closely follow guidance from the World Wide Web Consortium. Trimethoprim is given to kill bacteria but it also acts like amiloride, (a potassium-sparing diuretic) in the kidney. Converging lines of evidence support the notion that terminal hyperkalemia may explain our findings. Bactericidal antibiotics, as a class of drugs and irrespective of specific mechanisms of action, fundamentally and sometimes irrevocably, damage mitochondria. In contrast, we observed no increased risk of sudden death with the other antibiotics (table 3). 2015 Canadian Medical Association or its licensors. 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. inflammation of the alveoli of the lungs. Now consider older patients with lifestyle diseases, such as obesity, heart failure, diabetes and high blood pressure, conditions that impair organ function. I did not. 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. Thiamine is, after all, in most enriched and fortified foods. That means it is likely to be ignored by many health professionals. These are among the most popular blood pressure drugs in the pharmacy. Dear Doctor, I would like to express the deepest gratitude to you for writing and updating this website. All Rights Reserved.

Google Podcasts 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. Did you also note that the authors said millions of patients receive this antibiotic in combination with ARBs or ACE inhibitors? Although we used a validated algorithm to define sudden death,25 some degree of outcome misclassification is likely. Folate deficiency during pregnancy is associated with serious neurodevelopment aberrations including neural tube defects like spina bifida and thus Bactrim should be strongly contraindicated for pregnant women, but at least one small study found that 3.2% of the pregnant women sampled were prescribed Bactrim. The results showed that, in this specific patient population, 3 of every 1000 individuals taking either ACE inhibitors or ARBs who then begin treatment with trimethoprim/sulfamethoxazole will die suddenly within 7 to 14 days. I just finished a five day course of 800mg bactrim DS for a uti. At doses used in clinical practice (typically 80-160 mg twice daily), trimethoprim blocks the epithelial sodium channel (ENaC) in the distal nephron, impairing renal potassium elimination.11 12 Approximately 80% of patients receiving co-trimoxazole develop increases in serum potassium concentrations of at least 0.36 mEq/L and 6% develop frank hyperkalemia (potassium >5.4 mEq/L).13, We have previously shown that the use of co-trimoxazole with angiotensin converting enzyme inhibitors or angiotensin receptor blockers results in an almost sevenfold increase in the risk of hyperkalemia related hospital admission relative to amoxicillin.14 Case reports show that this drug interaction can cause life threatening hyperkalemia,15 16 but whether it can increase the risk of sudden death in clinical practice is unknown. CastBox Trimethoprim was among the drugs tested and found to potently block both thiamine transporters. But the researchers did not have any data on serum potassium concentrations. She has published and presented several articles on her findings. But as Ive learned more and more about pharmacology, Im amazed that we dont see more major drug interactions and side effects in folks who take multiple medications. 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. We suggest that, when clinically appropriate, clinicians either choose alternate antibiotics or limit the dose and duration of co-trimoxazole treatment. The blockade of the metabolism and uptake of these two critical nutrients is key to understanding the spectrum of adverse events associated with it, particularly those not directly induced by the sodium channel blockade that causes hyperkalemia. A similar question, how then, even after cessation of the drug do these individuals develop unremitting health issues indicative of longstanding thiamine deficiency? 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.

Additional demographic information came from the registered persons database, a registry of all Ontario residents with publically funded health insurance. In a case-control study of more than 1.6 million patients over 17 years, researchers from Canada found that cotrimoxazole was associated with a three-fold increased risk of sudden death when used in older patients (age > 66) taking angiotensin converting enzyme (ACE) inhibitors or angiotensin receptor blockers (ARBs). Your email address will not be published. But, I have so many great articles published in 2014 that I need to post about! In this population based study spanning 17 years, we found that co-trimoxazole was associated with sudden death in outpatients receiving angiotensin converting enzyme inhibitors or angiotensin receptor blockers. It is a structural analog of the vitamin-like compound para-aminobenzoic acid (PABA) found in several foods and involved in the metabolism of folic acid. The prescribing of co-trimoxazole with angiotensin converting enzyme (ACE) inhibitors or angiotensin receptor blockers (ARBs) results in a sevenfold increase in the risk of hospital admission with hyperkalemia relative to amoxicillin, Case reports have shown that this drug interaction can cause life threatening hyperkalemia, In older patients receiving ACE inhibitors or ARBs, co-trimoxazole was associated with an increased risk of sudden death; this may reflect sudden death from unrecognized severe hyperkalemia, When patients receiving ACE inhibitors or ARBs require an antibiotic, clinicians should either select antibiotics that do not contain trimethoprim or limit the dose and duration of trimethoprim based therapies, while closely monitoring the serum potassium concentration.
