Iatrogenic systemic botulism after intragastric botulinum neurotoxin injection: Case report.

BACKGROUND AND PURPOSE: The recent off-label use of botulinum neurotoxin (BoNT) for intragastric obesity treatment has led to 67 cases of systemic botulism in Türkiye, Germany, Austria and Switzerland. This case report highlights the potential risks and adverse effects associated with this treatment. CASE REPORT: A 36-year-old female presented to the emergency room with shortness of breath, fatigue, difficulty in eating and holding her head, constipation and double vision after receiving intragastric BoNT injection for obesity treatment. She had bilateral orbicularis oculi weakness, facial diplegia, weak tongue, masseter, neck and extremity muscles. Electromyography showed a presynaptic type neuromuscular junction disorder. The patient was admitted to the intensive care unit and administered botulinum heptavalent equine-derived antitoxin, but the medication had to be stopped due to a reaction. The patient was started on pyridostigmine for symptomatic treatment and was transferred to an inpatient clinic after minimal improvement. She was discharged after 7 days of follow-up. CONCLUSION: Clinicians should be cautious of the potential risks of intragastric BoNT injection for obesity treatment and consider systemic botulism as a potential adverse effect. Antitoxin treatment should be considered in clinically progressing patients despite negative botulinum toxin testing.

Safety and Clinical Outcomes of an Equine-derived Heptavalent Botulinum Antitoxin Treatment for Confirmed or Suspected Botulism in the United States.

BACKGROUND: Botulism is a rare, life-threatening paralytic illness. Botulism Antitoxin Heptavalent (A,B,C,D,E,F,G)-(Equine) (BAT) manufactured by Emergent BioSolutions Canada Inc is an equine-derived heptavalent botulinum antitoxin product indicated for the treatment of symptomatic botulism following documented or suspected exposure to botulinum neurotoxin serotypes A-G in adults and pediatric patients. BAT product was US-licensed in 2013. METHODS: In the United States, from October 2014 through July 2017, safety and clinical outcomes data were collected under a registry for patients treated with BAT product. RESULTS: Registry patients had a median age of 51 years (range, 32 days to 92 years). Among 162 patients, 7 (4.3%) experienced BAT product-related serious adverse events, including 1 (0.6%) report each of pneumonia, pneumonia aspiration, ventricular tachycardia, upper gastrointestinal hemorrhage, anaphylactic reaction, acute kidney injury, and acute myocardial infarction. Thirty-one (19.1%) patients had 41 BAT product-related adverse events. Six (3.7%) deaths were reported in the registry. All deaths were attributed to the underlying illness and were assessed as unlikely related to BAT product. Among 113 (69.8%) patients with a final diagnosis of botulism, those treated early (≤2 days) spent fewer days in the hospital (5 vs 15.5 days), in the intensive care unit (ICU) (4 vs 12 days), and on mechanical ventilation (6 vs 14.5 days) than those treated late (>2 days), respectively. CONCLUSIONS: BAT product was well tolerated in patients. Treatment with BAT product at ≤2 days of symptom onset was associated with shorter hospital and ICU stays, and shorter duration and need for mechanical ventilation, showing clinical benefit associated with early treatment.

Shot by a Gun Missed by a Provider.

BACKGROUND: Botulism is a paralytic disease caused by the neurotoxin produced by Clostridium botulinum. The majority of cases are due to ingestion or injection drug use. Wound botulism from traumatic injury is exceedingly rare, with only one to two cases reported each year in the United States. CASE REPORT: A 27-year-old man presented to the Emergency Department with diplopia, dysphagia, and progressive weakness 10 days after sustaining a gunshot wound to his right lower leg. He had been evaluated for the same complaints at a different facility the day prior and was discharged. His wound appeared well-healing, but a high suspicion for wound botulism led to rapid consultation with the state Poison Control Center and the Centers for Disease Control and Prevention. The patient developed worsening respiratory insufficiency and required mechanical ventilation. Expeditious treatment with equine heptavalent botulinum antitoxin resulted in significant recovery of strength in 4 days. Serum toxin bioassay tested positive for botulinum neurotoxin type A. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Wound botulism now accounts for the majority of adult botulism in the United States. It should be considered in any patient with signs of neuromuscular disease and a recent injury, even if the wound appears uninfected.

Efficacy of Antitoxin Therapy in Treating Patients With Foodborne Botulism: A Systematic Review and Meta-analysis of Cases, 1923-2016.

Background: Botulism is a rare, potentially severe illness, often fatal if not appropriately treated. Data on treatment are sparse. We systematically evaluated the literature on botulinum antitoxin and other treatments. Methods: We conducted a systematic literature review of published articles in PubMed via Medline, Web of Science, Embase, Ovid, and Cumulative Index to Nursing and Allied Health Literature, and included all studies that reported on the clinical course and treatment for foodborne botulism. Articles were reviewed by 2 independent reviewers and independently abstracted for treatment type and toxin exposure. We conducted a meta-analysis on the effect of timing of antitoxin administration, antitoxin type, and toxin exposure type. Results: We identified 235 articles that met the inclusion criteria, published between 1923 and 2016. Study quality was variable. Few (27%) case series reported sufficient data for inclusion in meta-analysis. Reduced mortality was associated with any antitoxin treatment (odds ratio [OR], 0.16; 95% confidence interval [CI], .09-.30) and antitoxin treatment within 48 hours of illness onset (OR, 0.12; 95% CI, .03-.41). Data did not allow assessment of critical care impact, including ventilator support, on survival. Therapeutic agents other than antitoxin offered no clear benefit. Patient characteristics did not predict poor outcomes. We did not identify an interval beyond which antitoxin was not beneficial. Conclusions: Published studies on botulism treatment are relatively sparse and of low quality. Timely administration of antitoxin reduces mortality; despite appropriate treatment with antitoxin, some patients suffer respiratory failure. Prompt antitoxin administration and meticulous intensive care are essential for optimal outcome.

Pediatric Botulism and Use of Equine Botulinum Antitoxin in Children: A Systematic Review.

Background: Botulism manifests with cranial nerve palsies and flaccid paralysis in children and adults. Botulism must be rapidly identified and treated; however, clinical presentation and treatment outcomes of noninfant botulism in children are not well described. Methods: We searched 12 databases for peer-reviewed and non-peer-reviewed reports with primary data on botulism in children (persons <18 years of age) or botulinum antitoxin administration to children. Reports underwent title and abstract screening and full text review. For each case, patient demographic, clinical, and outcome data were abstracted. Results: Of 7065 reports identified, 184 met inclusion criteria and described 360 pediatric botulism cases (79% confirmed, 21% probable) that occurred during 1929-2015 in 34 countries. Fifty-three percent were male; age ranged from 4 months to 17 years (median, 10 years). The most commonly reported signs and symptoms were dysphagia (53%), dysarthria (39%), and generalized weakness (37%). Inpatient length of stay ranged from 1 to 425 days (median, 24 days); 14% of cases required intensive care unit admission; 25% reported mechanical ventilation. Eighty-three (23%) children died. Median interval from illness onset to death was 1 day (range, 0-260 days). Among patients who received antitoxin (n = 193), 23 (12%) reported an adverse event, including rash, fever, serum sickness, and anaphylaxis. Relative risk of death among patients treated with antitoxin compared with patients not treated with antitoxin was 0.24 (95% confidence interval, .14-.40; P < .0001). Conclusions: Dysphagia and dysarthria were the most commonly reported cranial nerve symptoms in children with botulism; generalized weakness was described more than paralysis. Children who received antitoxin had better survival; serious adverse events were rare. Most deaths occurred early in the clinical course; therefore, botulism in children should be identified and treated rapidly.

Safety and Improved Clinical Outcomes in Patients Treated With New Equine-Derived Heptavalent Botulinum Antitoxin.

Background: Botulism is a rare, life-threatening paralytic illness. Equine-derived heptavalent botulinum antitoxin (HBAT), the only currently available treatment for noninfant botulism in the United States, was licensed in 2013. No reports have systematically examined safety and clinical benefit of HBAT among botulism patients. Methods: From March 2010 through March 2013, we collected data prospectively and through medical record reviews of patients with confirmed or suspected botulism who were treated with HBAT under an expanded-access Investigational New Drug program. Results: Among 249 HBAT-treated patients, 1 (<1%) child experienced an HBAT-related serious adverse event (hemodynamic instability characterized by bradycardia, tachycardia, and asystole); 22 (9%) patients experienced 38 nonserious adverse events reported by physicians to be HBAT related. Twelve (5%) deaths occurred; all were determined to be likely unrelated to HBAT. Among 104 (42%) patients with confirmed botulism, those treated early (≤2 days) spent fewer days in the hospital (median, 15 vs 25 days; P < .01) and intensive care (10 vs 17 days; P = .04) than those treated later. Improvements in any botulism sign/symptom were detected a median of 2.4 days and in muscle strength a median of 4.8 days after HBAT. Conclusions: HBAT was safe and provided clinical benefit in treated patients. HBAT administration within 2 days of symptom onset was associated with shorter hospital and intensive care stays. These results highlight the importance of maintaining clinical suspicion for botulism among patients presenting with paralytic illness to facilitate early HBAT treatment before laboratory confirmation might be available. Clinical consultation and, if indicated, HBAT release, are available to clinicians 24/7 through their state health department in conjunction with CDC.

Workgroup Report by the Joint Task Force Involving American Academy of Allergy, Asthma & Immunology (AAAAI); Food Allergy, Anaphylaxis, Dermatology and Drug Allergy (FADDA) (Adverse Reactions to Foods Committee and Adverse Reactions to Drugs, Biologicals, and Latex Committee); and the Centers for Disease Control and Prevention Botulism Clinical Treatment Guidelines Workgroup-Allergic Reactions to Botulinum Antitoxin: A Systematic Review.

Background: Naturally occurring botulism is rare, but a large number of cases could result from unintentional or intentional contamination of a commercial food. Despeciated, equine-derived, heptavalent botulinum antitoxin (HBAT) is licensed in the United States. Timely treatment reduces morbidity and mortality, but concerns that botulinum antitoxin can induce anaphylaxis exist. We sought to quantify the allergy risk of botulinum antitoxin treatment and the usefulness of skin testing to assess this risk. Methods: We conducted a systematic review of (1) allergic reactions to botulinum antitoxin and (2) the predictive value of skin testing (ST) before botulinum antitoxin administration. We searched 5 scientific literature databases, reviewed articles' references, and obtained data from the HBAT manufacturer and from the Centers for Disease Control and Prevention. Anaphylaxis incidence was determined for HBAT and previously employed botulinum antitoxins. We calculated the positive predictive value (PPV) and negative predictive value (NPV) of ST for anaphylaxis related to HBAT and other botulinum antitoxins. Results: Seven articles were included. Anaphylaxis incidence was 1.64% (5/305 patients) for HBAT and 1.16% (8/687 patients) for all other botulinum antitoxins (relative risk, 1.41 [95% confidence interval, .47-4.27]; P = .5). Observed values for both PPV and NPV for HBAT-ST (33 patients) were 100%. Observed PPVs and NPVs of ST for other botulinum antitoxins (302 patients) were 0-56% and 50%-100%, respectively. There were no reports of fatal anaphylaxis. Conclusions: Considering the <2 % rate of anaphylaxis, fatal outcomes, modest predictive value of ST, resource requirements for ST, and the benefits of early treatment, data do not support delaying HBAT administration to perform ST in a mass botulinum toxin exposure. Anaphylactic reactions may occur among 1%-2% of botulinum antitoxin recipients and will require epinephrine and antihistamine treatment and, possibly, intensive care.

Botulism During Pregnancy and the Postpartum Period: A Systematic Review.

Background: Maternal and fetal outcomes associated with botulism and botulinum antitoxin use during pregnancy and the postpartum period have not been systematically reviewed. Methods: We searched Global Health, Cochrane Library, Cumulative Index to Nursing and Allied Health Literature, Scopus, and Medline databases from inception to May 2015 for studies published on botulism or botulinum antitoxin use during pregnancy and the postpartum period, as well as the Centers for Disease Control and Prevention National Botulism Surveillance database. Our search identified 4517 citations. Results: Sixteen cases of botulism during pregnancy (11 in the third trimester) and 1 case during the postpartum period were identified. Ten cases were associated with confirmed or likely foodborne exposure; 2 cases were attributed to wound contamination related to heroin use, and the source of 5 cases was unknown. Eleven women with botulism had progressive neurologic deterioration and respiratory failure, requiring intensive care unit admission. Four women had adverse outcomes, including 2 deaths and 2 women who remained in a persistent vegetative state. No neonatal losses or cases of congenital botulism were reported. Among the 12 cases that reported neonatal data, 6 neonates were born preterm. No adverse maternal or neonatal events were identified as associated with botulinum antitoxin therapy among 11 patients who received it. Conclusions: Our review of 17 cases of botulism in pregnant/postpartum women found that more than half required ventilator support, 2 women died, and 6 infants were born prematurely. A high level of clinical suspicion is key for early diagnosis and treatment of botulism. Care of pregnant women or new mothers with botulism can include preparation for possible intubation.

A cluster of three cases of botulism due to Clostridium baratii type F, France, August 2015.

A cluster of three cases of food-borne botulism due to Clostridium baratii type F occurred in France in August 2015. All cases required respiratory assistance. Consumption of a Bolognese sauce at the same restaurant was the likely source of contamination. Clostridium baratii was isolated both from stool specimens from the three patients and ground meat used to prepare the sauce. This is the second episode reported in France caused by this rare pathogen.

Delayed Antitoxin Treatment of Two Adult Patients with Botulism after Cosmetic Injection of Botulinum Type A Toxin.

BACKGROUND: Injection of botulinum toxin type A for cosmetic purposes is common. It is believed to be safe, but adverse reactions have been reported, including dysphagia, generalized paralysis, respiratory depression, and death caused by focal injection of the toxin. Early administration of antitoxin in patients with adverse reactions is the mainstay of management, but the time window for its clinical efficacy is not well defined. CASE REPORTS: Two female adult patients with clinical botulism after botulinum toxin type A injection are described. Both patients had received intramuscular injection of botulinum toxin type A in their calves at beauty shops for cosmetic reasons. They developed clinical botulism about 3 days postinjection. They presented late to the emergency department. Monovalent type A botulinum antitoxin was administered 7 and 9 days from symptom onset, respectively. Both patients showed clinical improvement after the antitoxin treatment. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Patients may present to the emergency department with systemic effects of botulinum toxin type A after cosmetic injection. Clinical efficacy of botulinum antitoxin treatment was observed in two patients who were given the drug 7 and 9 days after the occurrence of symptoms of botulism after cosmetic injection of botulinum toxin type A. It may be worthwhile to commence antitoxin treatment even if patients present late.

Early diagnosis and treatment in a child with foodborne botulism.

INTRODUCTION: Foodborne botulism is a neuroparalytic disease caused by ingestion of food contaminated with botulinum toxins. Despite rare the mortality rate is high if untreated. Diagnosis of botulism is still a challenge for clinician, due to the variability of clinical manifestations and disease course. We report on a child with type B botulin intoxication who was early diagnosed and treated underlining that clinical suspicion is crucial to start prompt treatment. CASE PRESENTATION: An 11-year-old boy presented with bilateral ptosis and mydriasis, dry mouth, difficulty in swallowing, dysphonia, urine retention and constipation. Clear sensorium and no fever were observed. Immediately the suspicion of botulism was risen and botulinum antitoxin was administered. 3 days later serum and rectal samples tested positive for Clostridium botulinum. The patient completely recovered when discharged from hospital. DISCUSSION: Foodborne botulism is still possible in developed countries. The confirmation test of botulism requires some days. To avoid long delays between intoxication and diagnosis prompt clinical suspicion is thus crucial. The outcome depends on rapid implementation of appropriate management with intensive respiratory care and antitoxin administration.

[Clostridia: toxin masters. Botulism: from botox to sausages?]. / Clostridia: maîtres en toxines. Le botulisme: du botox au saucisson?

Clostridia are ubiquitous Gram-positive bacteria whose toxins are responsible for serious diseases. In this article we report a case of foodborne botulism we have recently managed. Moreover, we briefly describe the major clinical syndromes caused by different species of Clostridium (except for C. difficile infections, as this subject has been previously extensively reviewed in this journal). Botulism causes a flaccid paralysis starting with cranial nerves. Administration of botulism anti-toxin should be rapidly considered as soon as botulism is suspected, as prognosis is largely dependent on timely treatment; alerting the public health authorities is equally important. In Switzerland botulinum antitoxin can be obtained from the pharmacy of the Swiss Army.

Infant botulism due to C. butyricum type E toxin: a novel environmental association with pet terrapins.

We describe two cases of infant botulism due to Clostridium butyricum producing botulinum type E neurotoxin (BoNT/E) and a previously unreported environmental source. The infants presented at age 11 days with poor feeding and lethargy, hypotonia, dilated pupils and absent reflexes. Faecal samples were positive for C. butyricum BoNT/E. The infants recovered after treatment including botulism immune globulin intravenous (BIG-IV). C. butyricum BoNT/E was isolated from water from tanks housing pet 'yellow-bellied' terrapins (Trachemys scripta scripta): in case A the terrapins were in the infant's home; in case B a relative fed the terrapin prior to holding and feeding the infant when both visited another relative. C. butyricum isolates from the infants and the respective terrapin tank waters were indistinguishable by molecular typing. Review of a case of C. butyricum BoNT/E botulism in the UK found that there was a pet terrapin where the infant was living. It is concluded that the C. butyricum-producing BoNT type E in these cases of infant botulism most likely originated from pet terrapins. These findings reinforce public health advice that reptiles, including terrapins, are not suitable pets for children aged <5 years, and highlight the importance of hand washing after handling these pets.

Emergency department identification and critical care management of a Utah prison botulism outbreak.

STUDY OBJECTIVE: We report botulism poisoning at a state prison after ingestion of homemade wine (pruno). METHODS: This is an observational case series with data collected retrospectively by chart review. All suspected exposures were referred to a single hospital in October 2011. RESULTS: Twelve prisoners consumed pruno, a homemade alcoholic beverage made from a mixture of ingredients in prison environments. Four drank pruno made without potato and did not develop botulism. Eight drank pruno made with potato, became symptomatic, and were hospitalized. Presenting symptoms included dysphagia, diplopia, dysarthria, and weakness. The median time to symptom onset was 54.5 hours (interquartile range [IQR] 49-88 hours) postingestion. All 8 patients received botulinum antitoxin a median of 12 hours post-emergency department admission (IQR 8.9-18.8 hours). Seven of 8 patients had positive stool samples for type A botulinum toxin. The 3 most severely affected patients had respiratory failure and were intubated 43, 64, and 68 hours postingestion. Their maximal inspiratory force values were -5, -15, and -30 cm H2O. Their forced vital capacity values were 0.91, 2.1, and 2.2 L, whereas the 5 nonintubated patients had median maximal inspiratory force of -60 cm H2O (IQR -60 to -55) and forced vital capacity of 4.5 L (IQR 3.7-4.9). Electromyography abnormalities were observed in 1 of the nonintubated and 2 of the intubated patients. CONCLUSION: A pruno-associated botulism outbreak resulted in respiratory failure and abnormal pulmonary parameters in the most affected patients. Electromyography abnormalities were observed in the majority of intubated patients. Potato in the pruno recipe was associated with botulism.

Chronic botulism in a Saxony dairy farm: sources, predisposing factors, development of the disease and treatment possibilities.

The aim of this study is to investigate Clostridium botulinum at a Saxony dairy farm with 159 cows and 18 heifers. The animals exhibited clinical symptoms of chronic botulism. To determine the source of the infection, feces, blood, organs, and gastrointestinal fluids of dead or euthanized cows; as well as soil, water, silage and manure were tested for C. botulinum spores and BoNTs using ELISA. BoNT/C and C. botulinum type C were detected in 53% and 3% of tested animals, respectively, while BoNT/D and C. botulinum type D were detected in 18% of the animals. C. botulinum also was detected in organs, gastrointestinal fluids, drinking water and manure. To evaluate possible treatments, animals were given Jerusalem artichoke syrup (JAS), Botulism vaccine (formalinised aluminum hydroxide gel adsorbed toxoid of C. botulinum types C and D) or a suspension of Enterococcus faecalis. After four weeks treatment with JAS, BoNT/C and C. botulinum type C were not detected in feces. In contrast, BoNT/D and C. botulinum type D were not significantly influenced by the JAS treatment. Vaccination with botulism vaccine and the E. faecalis suspension significantly decreased BoNT/D and C. botulinum type D. A significant increase of Enterococci was detected in animals treated with E. faecalis. Interestingly, there was a negative correlation between the detection of both BoNT and C. botulinum with the concentration of Enterococci in feces. Although C. botulinum C and D antibodies increased significantly (p < 0.0001) after vaccination with the botulism vaccine, the reduction of C. botulinum and BoNT in feces did not result in recovery of the animals because they were deficient of trace elements [manganese (Mn), cobalt (Co), copper (Cu) and selenium (Se)]. Animals treated with trace elements recovered. It appears that intestinal microbiota dysbiosis and trace element deficiency could explain the extensive emergence of chronic Botulism.

[Familial occurrence of botulism - a case report]. / Familiarni vyskyt botulismu - kazuistika.

Botulism, a life-threatening condition, is very rare in the Czech Republic. Since 1960, a total of 155 cases have been reported; between 2010 and 2012, not a single case was identified. This is a case report of familiar occurrence of botulism following consumption of home-made pork and liver pâté in three family members admitted to the Department of Infectious, Tropical and Parasitic Diseases, Na Bulovce Hospital in Prague in May 2013. The neurological symptoms were dominated by diplopia and dysarthria. After administration of an antitoxin, all patients recovered. Given the poor availability of the antitoxin, a decision was made following this small family epidemic to have an emergency reserve of life-saving anti-infective drugs for the Czech Republic in the Toxicological Information Center in Prague.

Standardization of the Japanese National Standard, Equine Botulinum Antitoxin Type A, and Factors Affecting Standardization.

Equine botulinum antitoxin is one of the most popular countermeasures for human botulism. The unitage of the antitoxin product is defined according to national minimum requirement or pharmacopoeia in each country by referring to national standard antitoxins for four types (A, B, E, and F). With the expected depletion of the national standard antitoxins, replacement national standard antitoxins are produced and standardized through collaboration of the National Control Laboratory and other participants, including manufacturer(s). Therefore, Japanese National Standard Botulinum Antitoxin Type A, Equine, was replaced according to the results of a collaborative study involving the National Institute of Infectious Diseases and KM Biologics Co., Ltd. The unitage of the replacement material was determined through mouse neutralization tests, which involved toxin-antitoxin mixture injection at pH 7.0. Potency value of 440 units/vial was obtained. However, the Japanese Minimum Requirement for Biological Products was revised, and the neutralization reactions were repeated at pH 6.0, for which considerably different potency value (656 units/vial) and survival profile of mice were obtained. In September 2021, the replacement material, Japanese National Standard Botulinum Antitoxin Type A, Equine, lot 2, was established with potency value of 656 Units/vial. The impact of pH-dependent change in potency on antitoxin quality control is discussed.

Foodborne botulism outbreak with potential new management options.

OBJECTIVES: To shed some light on a potential therapeutic modality that may facilitate resolution of botulism symptoms, namely 3,4-diaminopyridine (3,4-DAP). METHODS: In Riyadh, Saudi Arabia, we recently encountered a foodborne botulism outbreak that, luckily, was discovered early. In Prince Sultan Military Medical city, we admitted, during a period of approximately 3 weeks, 15 probable cases, 2 of which were excluded due to more likely alternative diagnoses. We report in this case series 13 highly suspected cases of botulism that we encountered during the outbreak. RESULTS: A total of 12 out of 13 patients required intensive care unit (ICU) admission, one of which required intubation. Symptoms included cranial nerve palsies, gastrointestinal symptoms, limb and respiratory muscle weakness. Patients showed clinical improvement when received botulinum antitoxin and 3,4-DAP if given early in the course of the disease. CONCLUSION: Early admisntration of 3,4-DAP may facilitate recovery and prevent disease progression. Larger prospective trials should be carried out to confirm that.

Non-invasive diagnosis of diaphragmatic paralysis in botulism using ultrasound.

This case study explores foodborne botulism, a severe illness caused by botulinum neurotoxin-contaminated food. It leads to bilateral descending paralysis, involving the diaphragm. We highlight diaphragmatic ultrasound as a non-invasive diagnostic tool. A 50-year-old obese male developed diplopia and weakness after consuming contaminated food, rapidly progressing to severe symptoms. Mechanical ventilation became necessary due to respiratory failure. Diaphragmatic ultrasound confirmed bilateral diaphragm paralysis despite early antitoxin treatment. The patient experienced complications, requiring tracheostomy and rehabilitation. After five months, he fully recovered diaphragmatic function. This study underscores botulism's life-threatening nature and the vital role of supportive care. Diaphragmatic ultrasound is a safe and effective method for assessing diaphragmatic function in such cases, obviating ionizing radiation exposure. We recommend its routine use for evaluating botulism-induced paralysis.
