Severe Botulism after Intragastric Botulinum Toxin-A Injection: A Case Series

Intragastric botulismus toxin-A (BoNT-A) is one of the new approaches in the treatment of obesity. We aimed to contribute to the literature by presenting the clinical features, laboratory findings and treatment responses of iatrogenic botulism cases due to intragastric BoNT-A administered in our clinic. All detailed medical information was obtained by accessing the medical records of the patients who were hospitalized and followed up and treated between September 2022 and December 2022, and the diagnosis of A.05.1 Botulism was entered according to ICD-10, and whose clinical findings were compatible with botulism disease and who underwent intragastric BoNT-A application beforehand. These records were obtained by examining this information. 10 patients who developed botulism after intragastric BoNT-A application between 01/09/2022 and 28/02/2023 were followed up in our clinic. All of the patients were women. The mean age was 35. The mean hospital stay was 9 days. Only 1 of our cases required intensive care. Good response to treatment was accepted as a complete or near-complete improvement in the clinical findings of the patients and all of them had a good response to treatment. Intragastric BoNT-A administration is a procedure that requires careful indication with a profit/loss calculation considering the potential side effects. In addition, attention should be paid to dilution rates and dose amounts.

Botulinum Toxin-A for the Treatment of Voiding Dysfunction: Our Initial Experience

Objective: Evaluation of Botulinum Toxin-A (BTX-A) as an alternative treatment option in patients whom previous treatments were failed. Methods: Between March 2005 and September 2006, a total 19 patients;16 patients with overactive bladder (5 neurologic, 11 idiopathic), 2 with nocturnal enuresis, 1 with interstitial cystitis, intravesical BTX-A injection was applied. Except one patient, 18 patients with a median age 46 (20 - 80) were registered to the study. Patients were examined at postoperative 3 weeks and 6 months with ICIQ-SF (International Consultation on Incontinence Questionnaire-Short Form) and satisfaction forms used in our clinic. Results: The median follow-up time was 16 months (6 - 18). When evaluated according to diagnosis, symptoms were improved 100% in neurologic overactive bladder (5/5), 80% in idiopathic overactivity (8/10), 50% in nocturnal enuresis (1/2). In one patient with interstitial cystitis there was no improvement. Median efficiency time of BTX-A treatment was 6 months (1 - 17). At 3 weeks and 6 months after the treatment, ICIQ-SF score was decreased to 3.6 and 7.5 respectively from preoperative level of 18.7. Quality of life scores at preoperative, 3 week and 6 months were 9.7, 2.7 and 4.3 respectively. Except 3 patients with overactive neurologic bladder because of spinal cord injury, symptoms of patients with pollacuria and nocturia decreased at 3. week. Even if these rates increased at 6 months they still were significantly less than preoperative status. The spinal cord injured 3 patients had clean intermittent catheterization per 1 hour and had urinary incontinence between the catheterizations preoperatively, however at 3 weeks and 6 months the intervals of catheterisations was 4 hours and 3 hours respectively and also the urinary incontinance between the catheterisations improved. At patient satisfactions, 78% of patients declared that they were pleased and underwent the procedure again and will recommend it to their relatives with similar problems. One patient had a complication as tansient weakness on her legs. Conclusion: BTX-A injections provide an alternative treatment before surgery at overactive bladder especially for those who doesn’t response to medical treatment or cannot use antimuscarinics because of their side effects. Further studies with a greater number of patients are needed for determining the effectiveness of BTX-A on patients with voiding dysfunctions.

Botulinum toxin type A in treating early-stage patients with small-angle acute acquired comitant esotropia

AIM:To investigate botulinum toxin A(BTXA)efficacy on small-angle(≤25Δ)acute acquired concomitant esotropia(AACE)in early-stage patients.METHODS:The electronic medical record data of AACE patients during March 2019 and June 2023 were collected in this retrospective and hospital-based cohort study.A total of 72 small-angle AACE patients received BTXA extraocular muscle injection.Patients were grouped by onset-to-treatment time(Group A:≤6mo,Group B:>6mo).Deviation of esotropia,eye alignment and stereopsis were analyzed at the period of pre/post-injection(1wk,1,3,and 6mo).Orthophoria rate at 6mo(horizontal deviation<10Δand binocular single vision)were considered as outcome index.RESULTS:There were no significant baseline differences(P>0.05)between two groups except onset-to-treatment time(2mo vs 11mo,P<0.001).Higher orthophoria rates were in Group A at last follow-up(94.74%vs 73.53%,P=0.013).Post-BTXA deviations of two groups at 1mo showed no difference(P>0.05);while in 3 and 6mo Group A was significantly smaller than group B(all P<0.001).No statistically significant differences were observed among all post-BTXA deviations of near and distance in Group A.In Group B,deviation at 3mo(near:2Δvs 0,P<0.001;distance:4Δvs 0,P<0.001)and 6mo(near:6Δvs 0,P<0.001;distance:6Δvs 0,P<0.001)was significant increased compared to deviation at 1wk after treatment.Group A showed better stereopsis recovery in last follow-up compared to Group B(80″vs 200″,P=0.002).Both groups obtained improved stereopsis after treatment(Group A:80″vs 300″,P<0.001;Group B:200″vs 300″,P=0.037).CONCLUSION:BTXA is effective for AACE with small deviation(≤25Δ)in early stage.Delayed treatment(>6mo)may reduce BTXA efficacy.Early BTXA intervention benefits long-term eye alignment and stereopsis recovery.

Botulinum toxin type A-targeted SPP1 contributes to neuropathic pain by the activation of microglia pyroptosis

BACKGROUND Neuropathic pain(NP)is the primary symptom of various neurological condi-tions.Patients with NP often experience mood disorders,particularly depression and anxiety,that can severely affect their normal lives.Microglial cells are as-sociated with NP.Excessive inflammatory responses,especially the secretion of large amounts of pro-inflammatory cytokines,ultimately lead to neuroinflam-mation.Microglial pyroptosis is a newly discovered form of inflammatory cell death associated with immune responses and inflammation-related diseases of the central nervous system.METHODS Two models,an in vitro lipopolysaccharide(LPS)-stimulated microglial cell model and a selective nerve injury model using BTX-A and SPP1 knockdown treatments,were used.Key proteins in the pyroptosis signaling pathway,NLRP3-GSDMD,were assessed using western blotting,real-time quantitative polymerase chain reaction,and immunofluorescence.Inflammatory factors[interleukin(IL)-6,IL-1β,and tumor necrosis factor(TNF)-α]were assessed using enzyme-linked immuno-sorbent assay.We also evaluated microglial cell proliferation and apoptosis.Furthermore,we measured pain sensation by assessing the delayed hind paw withdrawal latency using thermal stimulation.RESULTS The expression levels of ACS and GSDMD-N and the mRNA expression of TNF-α,IL-6,and IL-1βwere enhanced in LPS-treated microglia.Furthermore,SPP1 expression was also induced in LPS-treated microglia.Notably,BTX-A inhibited SPP1 mRNA and protein expression in the LPS-treated microglia.Additionally,depletion of SPP1 or BTX-A inhibited cell viability and induced apoptosis in LPS-treated microglia,whereas co-treatment with BTX-A enhanced the effect of SPP1 short hairpin(sh)RNA in LPS-treated microglia.Finally,SPP1 depletion or BTX-A treatment reduced the levels of GSDMD-N,NLPRP3,and ASC and suppressed the production of inflammatory factors.CONCLUSION Notably,BTX-A therapy and SPP1 shRNA enhance microglial proliferation and apoptosis and inhibit microglial death.It improves pain perception and inhibits microglial activation in rats with selective nerve pain.

Dermal thickness,rather than drug concentration and injection speed,influences the effective area of botulinum toxin type A in the dermis

Background:Recently,microbotulinum,a new technique that involves injecting botulinum toxin type A(BoNTA)microdroplets into superficial cutaneous tissue,has gained popularity.The precise distribution of BoNTA in the targeted area profoundly affects outcomes.Many factors may influence the effective area of BoNTA in the dermis.This study aimed to determine the dermal distribution properties of BoNTA to guide microbotulinum injection.Methods:Ten healthy males aged 18–65 years without BoNTA treatment in the previous year were recruited to receive intradermal injections in the chest and back.Ultrasound was used to ensure the intradermal delivery of injections and measure the dermal thickness.The minor iodine starch test was performed at baseline and 3 days,7 days,21 days,1 month,and 2 months after treatment.Results:All participants received intradermal injections.The dermis was thinner on the chest(thickness,0.20±0.03 cm)than on the back(thickness,0.39±0.07 cm)(P<0.05).An injection in the thicker dermis had a significantly smaller effective area at every follow-up visit.The drug concentration did not affect the effective area except at 3 days after treatment.Injection speed did not influence the effective area at any follow-up visits.Conclusion:An injection in a thicker dermis leads to a smaller effective area for intradermal injections.When the BoNTA dose is the same,the drug concentration and injection speed do not matter.

Clinical effect of botulinum toxin type A combined with autologous fat grafting in patients with nasolabial fold depression

BACKGROUND Nasolabial fold(NLF)depression can affect the facial appearance of patients to some extent and increase their psychological burdens.In recent years,autologous fat grafting(AFG)combined with botulinum toxin A(BTX-A)injection(AFG+BTX-A injection)has been gradually applied in the treatment of patients with NLF depression.Although studies have been conducted on the efficacy and safety of AFG+BTX-A injection in treating NLF depression,the experimental design,observational indicators,and sample enrollment criteria vary remarkably,making it difficult to draw convincing and consistent conclusions.Thus,further relevant research is warranted.AIM To assess the esthetic improvement,efficacy,and safety of AFG+BTX-A injections in patients with NLF depression.METHODS This study included 60 patients with NLF depression who were treated in our hospital from February 2019 to April 2021.These patients were categorized into control(n=30)and observation(n=30)groups.The observation group received AFG+BTX-A injection,whereas the control group underwent AFG only.All patients were evaluated using the wrinkle severity rating scale(WSRS)and global aesthetic improvement scale.The compactness of facial contours,skin evaluation indexes,adverse reactions,and satisfaction of the two groups were evaluated 3 months postoperatively.RESULTS The WSRS scores of the observation group at 1,3,and 6 months postoperatively were lower than those of the control group(P<0.05).Three months postoperatively,facial fine lines and pores showed obvious improvement and the skin index score was higher in the observation group than in the control group(P<0.05).The compactness of facial contours was better in the observation group than in the control group(P<0.05).In addition,no remarkable differences were noted in the incidence of postoperative adverse reactions such as facial stiffness,facial asymmetry,facial bruising,and facial concavity inequality(P>0.05).CONCLUSION AFG+BTX-A injection is a highly safe,cost-effective,effective,and long-lasting treatment for NLF depression with high esthetic value,which should be promoted in the future.

Botulinum toxin type A injection combined with biofeedback in the treatment of spastic pelvic floor syndrome

BACKGROUND Spastic pelvic floor syndrome(SPFS)is a refractory pelvic floor disease characterized by abnormal(uncoordinated)contractions of the external anal sphincter and puborectalis muscle during defecation,resulting in rectal emptation and obstructive constipation.The clinical manifestations of SPFS are mainly characterized by difficult defecation,often accompanied by a sense of anal blockage and drooping.Manual defecation is usually needed during defecation.From physical examination,it is commonly observed that the patient's anal muscle tension is high,and it is difficult or even impossible to enter with his fingers.AIM To investigate the characteristics of anorectal pressure and botulinum toxin A injection combined with biofeedback in treating pelvic floor muscle spasm syndrome.METHODS Retrospective analysis of 50 patients diagnosed with pelvic floor spasm syndrome.All patients underwent pelvic floor surface electromyography assessment,anorectal dynamics examination,botulinum toxin type A injection 100 U intramuscular injection,and two cycles of biofeedback therapy.RESULTS After the botulinum toxin A injection combined with two cycles of biofeedback therapy,the patient's postoperative resting and systolic blood pressure were significantly lower than before surgery(P<0.05).Moreover,the electromyography index of the patients in the resting stage and post-resting stages was significantly lower than before surgery(P<0.05).CONCLUSION Botulinum toxin A injection combined with biofeedback can significantly reduce pelvic floor muscle tension in treating pelvic floor muscle spasm syndrome.Anorectal manometry is an effective method to evaluate the efficacy of treatment objectively.However,randomized controlled trials are needed.

Botulinum toxin type A for treating chronic low back pain:A double blinded randomized control study

BACKGROUND Low back pain(LBP)is a prevalent issue that orthopedic surgeons frequently address in the outpatient setting.LBP can arise from various causes,with stiffness in the paraspinal muscles being a notable contributor.The administration of Botulinum toxin type A(BoNT-A)has been found to alleviate back pain by relaxing these stiff muscles.While BoNT-A is approved for use in numerous conditions,a limited number of randomized clinical trials(RCTs)validate its efficacy specifically for treating LBP.AIM To study the safety and the efficacy of BoNT-A in minimizing pain and improving functional outcomes in patients of chronic LBP(CLBP).METHODS In this RCT,adults aged 18-60 years with mechanical LBP persisting for at least six months were enrolled.Participants were allocated to either the Drug group,receiving 200 Ipsen Units(2 mL)of BoNT-A,or the Control group,which received a 2 mL placebo.Over a 2-month follow-up period,both groups were assessed using the Visual Analog Scale(VAS)for pain intensity and the Oswestry Disability Index(ODI)for disability at the start and conclusion of the study.A decrease in pain by 50%was deemed clinically significant.RESULTS The study followed 40 patients for two months,with 20 in each group.A clinically significant reduction in pain was observed in 36 participants.There was a statistically significant decrease in both VAS and ODI scores in the groups at the end of two months.Nonetheless,when comparing the mean score changes,only the reduction in ODI scores(15 in the placebo group vs 16.5 in the drug group,clinically insignificant)was statistically significant(P=0.012),whereas the change in mean VAS scores was not significant(P=0.45).CONCLUSION The study concludes that BoNT-A does not offer a short-term advantage over placebo in reducing pain or improving LBP scores in CLBP patients.

Prospective observational study to assess the validity of the functional disability score in patients with blepharospasm,hemifacial spasm and synkinesis treated with botulinum toxin injection

Background:Benign essential blepharospasm(BEB),aberrant facial nerve degeneration and hemifacial spasm(HFS)are all examples dystonia which,though not life-threatening,can have a significant impact on patient quality of life.The need for reliable self-rating surveys to monitor functional disability is fundamental.The Blepharospasm Disability Index(BSDI)is already a widely utilised and validated selfrating score for blepharospasm whilst the functional disability score(FDS)requires further validation.The principle aim of this study is to repeat validation of the FDS against the BSDI,which has been validated by several groups since its original description but only in patients with BEB.Methods:A randomised blinded prospective cohort study was conducted at a single unit on 38 patients with BEB,aberrant facial nerve degeneration and HFS.Patients were blinded to complete the FDS followed by the BSDI or the BSDI followed by the FDS with a 30-minute interval.Results:Both the FDS and BSDI were found to be reliable with high internal consistency and test-retest reliability.Both scales were also found to be moderately correlated with the Jankovic disease severity score.Conclusions:This study is the first to use the FDS as a rating scale in patients with HFS and aberrant facial nerve degeneration.It is also the first study to formally validate the FDS as an acceptable rating scale for patients with dystonia and in particular it provides validation for its use in patients with HFS and aberrant facial nerve degeneration.

Systematic evaluation of the efficacy and safety of botulinum toxin type A in the treatment of spastic cerebral palsy

Background:Botulinum toxin type A(BTX-A)is a neuromuscular blocking agent.BTX-A inhibits acetylcholine release,causes neuromuscular transmission impairment,and decreases muscle spasms.Objective:To explore the efficacy and safety of BTX-A injection in the treatment of spastic cerebral palsy through systematic evaluation and to provide a reference for the clinical use of BTX-A.Methods:We used“Cerebral palsy”and“BTX-A”as the subject terms and used a combination of subject terms and free words for the search.We searched 7 databases,including CNKI,Wanfang,VIP,Sinomed,PubMed,Embase,and Web of science.Based on the inclusion and exclusion criteria,we screened the articles by reading their titles,abstracts,and full texts and finally included relevant literature for systematic evaluation.Result:A total of 93 papers were systematically evaluated,revealing that BTX-A injection treatment can effectively reduce muscle tone,increase joint mobility,improve gait and motor posture,and enhance gross motor movements in patients with spastic cerebral palsy.The benefits of BTX-A treatment can be sustained for 3–6 months,with motor ability improvement lasting up to 1 year.Combining BTX-A treatment with rehabilitation or external fixation therapy can enhance its efficacy.However,the effectiveness of BTX-A treatment is influenced by several factors,such as the dosage,number of injections,and patient age.Adverse reactions to BTX-A treatment are typically mild and can be relieved within 1–2 weeks.Conclusion:BTX-A injection is relatively safe but reversible.
