That retrospective study used the administrative health records, spanning 18 years, of more than 200,000 patients prescribed spironolactone. Thank you for bringing attention to the dangers of cotrimoxazole. We conduct ongoing accessibility reviews and remediate any functionality issues. Did you also note that the authors said millions of patients receive this antibiotic in combination with ARBs or ACE inhibitors? After just a few days on Bactrim I started experiencing rapid heart rate, hyperventilation-type symptoms, numbness and insomnia. Although I did not spend any time covering Keflex, the second drug prescribed to this individual, I would like to note that it too damages mitochondria, albeit by different mechanisms. Compared with amoxicillin, trimethoprim-sulfamethoxazole was associated with a more than twofold increase in the risk of sudden death (adjusted OR 2.46, 95% confidence interval [CI] 1.55-3.90). 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. Results Of 39 879 sudden deaths, 1027 occurred within seven days of exposure to an antibiotic and were matched to 3733 controls. Trimethoprim was among the drugs tested and found to potently block both thiamine transporters. In sum, it has become compellingly apparent that eukaryotic cells and complex organ systems cannot survive without the synergistic complex interactions of competent enteric bacteria and evolutionarily fashioned mitochondria, but go ahead and just cover him with some Bactrim. 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. Folate, or vitamin B9 is essential for DNA synthesis and repair. 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. The cases and controls were very different (the sudden-death cases were more likely to have heart failure, renal failure, and more co-morbidities). Given the large number of gut bacteria in comparison to eukaryotic cells, which also contain evolutionary derived mitochondria (mitochondria are believed to originate from bacteria and as such share similar enzymes and metabolic pathways with them), it would seem that the blockade of these critical nutrient pathways while effectively antibacterial, may also, induce unintended harm. Bactrim is also sold under the names: Septra, Sulfatrim, Septrin, Apo-Sulfatrim, SMZ-TMP and cotrimoxazole. This was only recently discovered by accident. Bicycle, Scooter, and Electric Bike Accidents, Cerebral Palsy Malpractice Injury Lawsuits, Stevens Johnson Syndrome (SJS) Disease Injury Lawyers, Clergy Sexual Abuse Lawyers | Priest Abuse Attorneys, Pennsylvania Sexual Abuse Lawsuit Lawyers, Sudden Death in Those Taking Bactrim Along with ACE Inhibitors or ARBs, Bicycle, Scooter, and Electric Bike Accident, Stevens Johnson Syndrome (SJS) Disease Injury. As such, it is critically important during reproduction for all organisms from bacteria to human. HHS Vulnerability Disclosure, Help MF drafted the manuscript, which was critically revised for important intellectual content by all authors. The thickening makes it hard for the heart to pump blood and can cause fast heartbeats. unsteadiness, trembling, or other problems with muscle control or coordination. Of the 1,601,542 patients in this cohort treated with either anACE-inhibitoror ARB, 39,879died suddenly. Thiamine is, after all, in most enriched and fortified foods. Thank you for writing this. It is prescribed for everything from acne and UTIs to prophylactic treatments associated with HIV. 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. Nowhere on the death certificate will it say, This patient died because of a drug interaction mistake.. Careers. Prescriptions disepensed in the community: England 2002-2012. We will be forever grateful to all for the help they provided. More commonly, thiamine insufficiency is associated with a litany of dysautonomic syndromes, although it is not widely recognized as such. In the primary analysis, co-trimoxazole was associated with a significantly increased risk of sudden death within seven days relative to amoxicillin (unadjusted odds ratio 1.83, 95% confidence interval 1.50 to 2.24), and this result persisted after adjustment using the disease risk index (1.38, 1.09 to 1.76). Although trimethoprim inhibits dihydrofolate reductase in bacteria, it is estimated that an approximately 50,000 times increased concentration of the drug is required to inhibit the human form of this enzyme.. How many of those 250 million ACE/ARB prescriptions could have been avoided if exercise was seen asa medicine,or if elderly patients had been deprescribed? In this analysis, we again observed an increased risk of sudden death with co-trimoxazole relative to amoxicillin (adjusted odds ratio 1.54, 1.29 to 1.84). Trimethoprim-induced hyperkalemia: An analysis of reported cases. The question one must ask is how presumably healthy individuals develop thiamine insufficiency upon the usage of drugs like Bactrim. Importantly, bacterial synthesis of folate and other B vitamins, represents a critical pathway not only for nutrient availability of the human host, but for managing the vast microbial ecosystems in a manner favorable to host survival. 2007b). Results: To avoid the potential confounding effects of changes in antibiotic selection and prescribing practices over time, controls were assigned exactly the same index date as cases. "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.". Our Firm Brochure Video Vault FAQS Recently In The News Press Releases Locations New York Attorneys Long Island Attorneys Results: Of the 11968 patients who died of sudden death while receiving spironolactone, we identified 328 whose death occurred within 14 days after antibiotic exposure. Now we dont really know if there is a causal relationship between use of trimethoprim-sulfamethoxazole and sudden death, and we can only speculate on what may be the reasons behind the association. Each case was matched with up to four controls on age, sex, chronic kidney disease, and diabetes. document.getElementById( "ak_js_1" ).setAttribute( "value", ( new Date() ).getTime() ); This site uses Akismet to reduce spam. This is addition to a spectrum of neuropsychiatric manifestations from depression to dementia that are associated with this critical nutrient. However, with this new study, we wanted to bring awareness about a drug interaction which causes dangerously high potassium levels that some physicians and pharmacists may not be aware of, he says. inflammation . 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. The Canadian researchers reported that many of the patients they were tracking died suddenly within one to two weeks of starting this combination. If you are unable to import citations, please contact Trimethoprim-sulfamethoxazole is frequently prescribed for urinary tract infections, with more than 20 million prescriptions written every year in the United States for a variety of infections, the researchers said in background information. Main outcome measure Odds ratio for the association between sudden death and exposure to each antibiotic relative to amoxicillin, after adjustment for predictors of sudden death according to a disease risk index. However, we dont have any data on serum potassium concentrations. Those who got the combo were almost seven times more likely to be hospitalized for problems due to high potassium compared to people taking different antibiotics (Archives of Internal Medicine, June 28, 2010). Lessons to be had. Of the 1,601,542 patients in the study treated with either anACE-inhibitoror ARB, 39,879died suddenly. Canadian Institutes of Health Research/Canada, NCI CPTC Antibody Characterization Program. Pocket Casts Within the cohort of patients receiving an angiotensin converting enzyme inhibitor or angiotensin receptor blocker, we defined case patients as those who died suddenly by using an approach validated previously (positive predictive value 87%).25 This definition was validated using linked Medicaid databases and death certificates to identify international classification of disease (ICD) codes consistent with sudden death (that is, sudden death, conduction disorders, dysrhythmias). Thank you so much for this article. There is a global crisis of antibiotic resistance, and urinary tract infections (UTIs) may be the canary in the coal mine. I am running out to pick up some vitamins asap. No endorsement by ICES or the Ontario MOHLTC is intended or should be inferred. An interaction between the commonly prescribed antibiotic co-trimoxazole and blood pressure drugs such as lisinopril or valsartan can cause sudden death. PMC Sigh. Before However, this applies equally to all the antibiotics we studied. I just finished a five day course of 800mg bactrim DS for a uti. So at a very minimum, Ill keep a closer eye on those potassium levels. I much prefer deprescribing. Bactericidal antibiotics, as a class of drugs and irrespective of specific mechanisms of action, fundamentally and sometimes irrevocably, damage mitochondria. But short-sighted physicians (and others), who dont look at multi-symptom, chronic illness as a possible effect of a class of antibiotics (FQs are chemo drugs masquerading as antibiotics) think that they have a better safety record than sulfa drugs. Enthusiasm is brimming. Remember, in order to get to usable folate THF, we need the DFT enzyme to work. In addition to blocking folate metabolism, the trimethoprim component of Bactrim also blocks thiamine uptake. Although, the spironolactone + Bactrim > sudden death relationship is studied typically only in the elderly, both drugs are increasingly common in adolescents and young women and may account for a good percentage of the adverse events in these populations that are considered idiopathic. When clinically appropriate, alternative antibiotics should be considered in these patients. I had never taken ACE/ARBs. It was an impossible task. Methods: of sudden death using a disease risk index. 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. 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. Please enable it to take advantage of the complete set of features! I was first diagnosed with severe osteoporosis when I was thirteen years old. When appropriate, alternative antibiotics should be considered in such patients. Each of the two drugs that make up Bactrim block microbial folate synthesis precipitating complete folate deprivation in bacteria, capable of resulting in folate deficiency non-bacterial cells. For a more in-depth discussion on this paper, check out the editorial hereor this wonderful post on #NephJC. Dear Doctor, I would like to express the deepest gratitude to you for writing and updating this website. I can hardly eat ! Here is a link to the full article in the British Medical Journal. Control patients were required to be alive at the index date and, like cases, received one of the study antibiotics in the seven days preceding the index date. The longer I practice medicine, the more nervous I get about medications, especially when patients are already on other drugs for chronic diseases. 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. Yes, I would like to support Hormones Matter. Mitochondrial ATP is requisite for cell functioning globally, as such decrements to ATP affect every organ and tissue in the body, but are most damaging where a consistent supply of ATP is requisite for survival in the heart and the brain. 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. 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.
