We report the case of a previously healthy woman in her 60s who presented to the emergency department with acute confusion, vomiting and fever. She was recently diagnosed with a urinary tract infection as an outpatient and had completed the fifth day of a 7-day course of treatment with nitrofurantoin. We maintained a wide differential diagnosis including infectious, metabolic, autoimmune and medication-related causes. She developed an acute normocytic anaemia in hospital with a haemoglobin drop from 121 g/L to 89 g/L. Further investigation revealed evidence of haemolysis with an elevated bilirubin, lactate dehydrogenase, reticulocyte count and decreased haptoglobin. She was worked up for both inherited and acquired causes of haemolysis and found to have glucose-6-phosphate dehydrogenase deficiency. Her presentation was thought to be secondary to nitrofurantoin-induced haemolysis and she recovered completely with conservative management through intravenous fluids and discontinuation of nitrofurantoin. Nitrofurantoin is recommended by both the Canadian and American Urological Association as a first-line antibiotic for uncomplicated urinary tract infections (UTIs),1 even though it only exerts bactericidal effects in the urine when reacting with susceptible bacteria at therapeutic doses.2 As a commonly prescribed antibiotic, clinicians should be aware of its broad side effect profile. Nitrofurantoin is frequently associated with nausea, vomiting, diarrhoea and loss of appetite.2 It has also been associated with severe adverse events such as pulmonary toxicity, hepatotoxicity and peripheral neuropathy. Haemolytic anaemia in individuals with glucose-6-phosphate dehydrogenase (G6PD) deficiency is another possible side effect, which may be easily overlooked, …","PeriodicalId":11277,"journal":{"name":"Drug and Therapeutics Bulletin","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139663077","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Acute cholestasis is one of the most common forms of hepatotoxicity induced by azathioprine. It usually begins during the first year of treatment, with most cases reported during the first month. We describe an uncommon case of DILI that occurred after 22 months of drug administration. A woman in her 50s was hospitalised because of jaundice and asthenia. She had been treated with azathioprine for myasthenia gravis during the last 2 years. Acute cholestatic injury was diagnosed. After ruling out most common causes of cholestasis, azathioprine was withdrawn and subsequent histological findings in liver biopsy were consistent with drug-induced cholestatic liver damage. After discontinuation of azathioprine, biochemical parameters progressively normalised and remarkable clinical improvement was achieved. With this report, we suggest that azathioprine should be considered among the causes of liver injury, despite long treatment duration. Drug-induced liver injury (DILI) is the most common cause of acute liver failure in high-income countries.1 Most cases are idiosyncratic and involve immune-mediated mechanisms which are independent of the dose used. In population-based studies, the incidence of DILI ranges between 13.9 and 19.1 cases per 100.000 people per year,1 a figure likely flawed by systematic under-reporting. Identification of the liable drug and its prompt discontinuation are critical to achieve patient recovery. Azathioprine is an immunosuppressive drug that works by inhibiting lymphocyte proliferation, thus limiting inflammatory and autoimmune responses. Azathioprine is a well-known cause of DILI, with an incidence of 1 case per 1103 users.2 Most cases of azathioprine-induced liver injury have been reported between the first month3 4 and the first year5–12 of treatment, while only a few cases of DILI have been described in long-term users of azathioprine.13 14 In the present …","PeriodicalId":11277,"journal":{"name":"Drug and Therapeutics Bulletin","volume":"24 1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139663219","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These will include cases that involve recently marketed drugs for which there is limited knowledge of adverse effects and cases that highlight unusual reactions to drugs that have been marketed for several years. We present a case of a young man who developed sudden deterioration in his physical and mental state whilst being treated as an inpatient for substance-induced psychosis. This deterioration was manifested by sudden disorientation, change in behaviour and visual hallucinations. It was only after excluding other potential causes that this presentation was attributed to the regular administration of procyclidine that was being used to counteract the extrapyramidal side effects from antipsychotics. The patient showed a dramatic improvement on stopping procyclidine. This case highlights the importance of awareness of rare adverse drug reactions and the resultant distressing effect for the patient himself. Antipsychotics are the mainstay of treatment of psychosis. They are well known for their extrapyramidal side effects (EPSEs) that greatly impact a patient’s well-being, including stiffness, tremor, difficulty eating and writing. Procyclidine is commonly prescribed to alleviate EPSEs. It does so by inhibiting the action of acetylcholine at the muscarinic receptor, hence minimising its excitatory effects.1 Reported side effects of procyclidine include most commonly drowsiness, dizziness, constipation, flushing, nausea, nervousness, blurred vision and dry mouth. Rarely, it is reported to cause abdominal pain, difficulty swallowing, urinary retention, weakness, chest pain, fainting, fever, tachycardia, arrhythmias, change in mental state (such as confusion, hallucinations, memory problems), mydriasis and visual changes.1 2 Being an anticholinergic, anticholinergic delirium is a possible, although rare, adverse effect of procyclidine.

These will include cases that involve recently marketed drugs for which there is limited knowledge of adverse effects and cases that highlight unusual reactions to drugs that have been marketed for several years. A woman in her mid-60s, without known liver disease, was admitted to the hospital with a partial malignant colonic obstruction. Over a 6-day course, she received a total of 13 g of intravenous acetaminophen not exceeding 4 g over a 24-hour period. She developed encephalopathy and an international normalised ratio of 6.1 meeting criteria for acute liver failure (ALF). She was treated with intravenous N-acetyl cysteine and other causes of liver failure were excluded. The patient was discharged with subsequent resolution of encephalopathy and improvement of her liver chemistries. Though ALF is rare, in countries where acetaminophen is readily available, almost 50% of ALF cases are acetaminophen-induced hepatotoxicity and most have been documented as oral ingestion of acetaminophen. We present a rare case of intravenous acetaminophen-induced ALF. Acute liver failure (ALF) is defined as new onset coagulopathy with international normalised ratio (INR) ≥1.5 and encephalopathy without pre-existing cirrhosis.1 Drug-induced liver injury (DILI) is the most common cause of ALF in the USA occurring at a rate of 20 cases per 100 000 persons.2 3 Of all DILI cases, acetaminophen-induced hepatotoxicity accounts for up to 46% of ALF cases.2 The two main aetiologies of acetaminophen overdoses are either intentional, often in context of suicide attempts, and unintentional overdoses, also known as therapeutic misadventures.3 4 Bower et al conducted a population-based surveillance for ALF that noted 55% of all acetaminophen-related ALF cases to be therapeutic misadventures.5 Current US Food and Drug Administration packaging …","PeriodicalId":11277,"journal":{"name":"Drug and Therapeutics Bulletin","volume":"4 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139656072","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
