A Propensity Score Matching Study on the Effect of OnabotulinumtoxinA Alone versus Short-Term Psychodynamic Psychotherapy Plus Drug-of-Choice as Preventive Therapy in Chronic Migraine: Effects and Predictive Factors. Eur Neurol 2022; 85:453-459. [PMID: 35772386 DOI: 10.1159/000525152] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/14/2021] [Accepted: 04/11/2022] [Indexed: 11/19/2022]
Abstract
OBJECTIVE The objective of this study was to test the superiority of multidisciplinary approach, that is, Short-Term Psychodynamic Psychotherapy (STPP) plus drug of choice, versus monotherapy, that is, OnabotulinumtoxinA (OnaBoNT-A). METHOD We consecutively recorded data from chronic migraine (CM) patients, with or without medication overuse headache (MOH), who underwent STPP or OnaBoNT-A, with a 3-month follow-up schedule. Headache days and analgesics intake were monitored as primary outcome measures. Propensity score matching (PSM) was used to eliminate discrepancies between groups. Discriminant function analysis (DFA) was used to pinpoint predictive factors associated with the clinical response. RESULTS 96 patients with CM (64% with MOH) were treated with STPP and 54 (59% with MOH) with OnaBoNT-A. At baseline, OnaBoNT-A patients had more failed preventive therapies, more years of illness and chronicity, and were older; STPP patients were more depressed and had a higher HIT-6. Both STPP and OnaBoNT-A patients showed a significant reduction of headache days (STPP: -14 vs. OnaBoNT-A:-14.3) and analgesics intake (STPP: -12,3 vs. OnaBoNT-A -13.5 pills/month), respectively. MOH diminished more in STPP, adherence was higher in OnaBoNT-A. Results were confirmed after PSM balancing of the groups for those variables that resulted as different (but age). CONCLUSION OnaBoNT-A monotherapy produced similar results to psychotherapy plus medication, after correcting for baseline differences.

Zandieh A, Cutrer FM. OnabotulinumtoxinA in chronic migraine: is the response dose dependent? BMC Neurol 2022; 22:218. [PMID: 35698027 PMCID: PMC9190093 DOI: 10.1186/s12883-022-02742-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/14/2021] [Accepted: 04/01/2022] [Indexed: 11/18/2022] Open
Abstract
Background OnabotulinumtoxinA has been widely used for control of chronic migraine. The aim of the current study was to evaluate the efficacy of different doses of the onabotulinumtoxinA therapy in patients with chronic migraine. Methods This is a retrospective paired comparison study on patients with chronic migraine who received at least 3 rounds of 150 units of onabotulinumtoxinA followed by at least 3 rounds of 200 units of onabotulinumtoxinA. The data from the patient-reported questionnaires about headache days, severe headache days and wearing off periods were reviewed. Results A total of 175 patients were included in this study. The headache days and severe headache days decreased from 13.62 ± 10.79 and 5.88 ± 6.73 to 11.02 ± 10.61and 4.01 ± 4.89 days, after increase in the onabotulinumtoxinA dose, respectively (P < 0.001 for both comparisons). The favorable effect of the 200 units compared to the 150 units of the onabotulinumtoxinA, was independent from the headache location and the duration of the onabotulinumtoxinA 150 units therapy; and persisted as patients continued to receive the higher dose of onabotulinumtoxinA. Increase in the onabotulinumtoxinA dose was also associated with a decreased wearing off period (P < 0.05). Conclusion We found that increase in the onabotulinumtoxinA is associated with fewer headache and severe headache days. Future randomized clinical trials are needed to confirm the dose-dependent response to onabotulinumtoxinA.

Abstract
OBJECTIVE To assess the impact of duration of antibiotic prophylaxis on incidence of UTI after intravesical OnabotulinumtoxinA (BTX) injection. METHODS A retrospective cohort study of patients with overactive bladder (OAB) who underwent office BTX injections from 2014-2020. UTI incidence within 30 days of BTX was compared between three durations of antibiotic prophylaxis: no antibiotic, single day, or multiple day course. Association of UTI with units of BTX, BMI, history of diabetes, immunosuppression, neurogenic OAB, chronic catheter, or recurrent UTI were investigated. RESULTS 290 patients and 896 cycles of BTX injections were included: 877 injections (97.7%) were women, with mean age 61.4 years (range 20-96; SD 13.3). No antibiotic prophylaxis was given to 112 (12.5%) patients, 595 (66%) received a single day, and 189 (21%) received a multiple day regimen (3-7 days). Overall incidence of UTI within 30 days was 11.4%. On multivariable logistic regression, use of any antibiotic prophylaxis was associated with a lower incidence of UTI (single OR 0.34; 95% CI 0.19-0.61; p<0.001; multiple OR 0.47; 95% CI 0.24-0.92; p=0.029), with no difference between single and multiple day regimens (OR 1.38; 95% CI 0.80-2.38; p=0.249). History of recurrent UTI (OR 3.77; 95% CI 2.23-6.39; p<0.001) and chronic suprapubic catheter (OR 2.88; 95% CI 1.04-7.95; p=0.041) were additional predictors. CONCLUSION A multiple day regimen of antibiotic prophylaxis was not more effective than a single day in preventing UTI for intravesical BTX injection. Use of any antibiotic prophylaxis was associated with a significantly lower incidence of UTI compared to no antibiotic.

[PMID: 35622543 PMCID: PMC9145697 DOI: 10.3390/toxins14050296] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/27/2022] [Revised: 04/18/2022] [Accepted: 04/20/2022] [Indexed: 11/16/2022] Open
Abstract
We aimed to provide insights on the role of the circadian time of administration in influencing the efficacy and tolerability/safety profile of OnabotulinumtoxinA (BoNTA) for chronic migraine (CM) prophylaxis. Methods: We retrospectively reviewed the medical files of BoNTA-naïve patients with CM who completed three consecutive cycles of treatment, according to the standard PREEMPT paradigm. Participants were classified to those scheduled to be treated in the morning hours from 8:00 to 12:00 (AM) or afternoon hours from 13:00 to 18:00 (PM). We then assessed and compared between groups the changes from baseline (T0—trimester before BoNTA’s first administration) to the period after its third administration (T3) in the following efficacy outcomes: (i) mean number of headache days/month, (ii) mean number of days/month with peak headache intensity of >4/10, (iii) mean number of days/month with consumption of any abortive treatment. Safety−tolerability was also compared between groups. Results: A total of 50 AM and 50 PM-treated patients were evaluated. The within-group analysis in both groups showed a significant decrease in all efficacy variables between T0 and T3. However, the between-group comparisons of all BoNTA-related efficacy outcomes at T3 vs. T0 documented comparable improvements between AM vs. PM-treated patients. Safety/tolerability was also similar between groups. Conclusions: We were not able to identify significant differences between patients treated in the AM vs. PM, so as to demonstrate that the circadian time of administration should be considered before initiating BoNTA in CM patients.

Abstract
PURPOSE OF REVIEW While most women with migraine improve during pregnancy, a subset may remain unchanged or even become more severe. Given the limited evidence for the use of prescription medications during pregnancy, many look to other treatment modalities. We seek to review complementary and integrative medicine, procedural interventions, and neurostimulation to empower women with safe and effective treatment options during pregnancy. RECENT FINDINGS Migraine treatment during pregnancy remains controversial. While evidence is limited, prospective and retrospective reviews, as well as clinical experience support the use of nutraceuticals, procedural interventions, and neurostimulation during pregnancy when the appropriate risks and benefits are weighed. Empowering patients with information on complementary and integrative medicine, as well as non-systemic and interventional treatments, may help to reduce anxiety and headache burden during pregnancy. Various nutraceuticals have shown promise for the preventive management of migraine. Non-systemic interventions such as trigger point injections and peripheral and sphenopalatine nerve blocks offer effective treatment options with minimal side-effects. Options for neurostimulation have expanded in recent years and may offer safe and effective non-pharmacologic options for the management of migraine. It is imperative that providers do not minimize migraine during pregnancy and become aware of the treatment modalities available to help guide women through this experience.

Abstract
INTRODUCTION AND HYPOTHESIS Dysfunctional voiding (DV) is not uncommon in women and is typically challenging to treat. This study retrospectively investigated the long-term treatment outcomes of DV women with different videourodynamics (VUDS) characteristics. METHODS Data of women with VUDS-proven DV (n = 302) were retrospectively analyzed. All patients at first received biofeedback pelvic floor muscle training and medications; urethral sphincter botulinum toxin A injection was administered after treatment failure. Long-term follow-up outcomes were graded by global response assessment (GRA) and objective responses of decrease of detrusor pressure (Pdet), increase in maximum flow rate (Qmax) and voiding efficiency (VE). The treatment outcomes were investigated among different VUDS subgroups. RESULTS Of 302 women, 165 (54.6%) had mid-urethral DV, 117 (38.7%) had distal urethral DV, and 20 (6.6%) had both bladder neck dysfunction (BND) and mid-urethral DV. A total of 170 (56.3%) patients were available for follow-up VUDS after treatment. Pdet was decreased in all three subgroups, but increase in Qmax and VE was only noted in the BND plus DV subgroup. Overall, 120 (70.6%) patients showed improvement (GRA ≥ 1), including 14 with BND plus DV (93.3%), 50 with mid-urethral DV (60.8%) and 56 with distal urethral DV (77.8%) (p = 0.044). All three subgroups showed significant reduction in bladder outlet obstruction index after treatment, with BND plus DV subgroup showing the greatest reduction. CONCLUSIONS Women with DV have different VUDS characteristics resulting from different pathophysiological mechanisms and treatment results. The VUDS characteristics may help predict treatment outcomes of female DV.

Abstract
OBJECTIVE Chronic migraine encephalalgia (CME) with concomitant temporomandibular disorder (TMD) is a serious illness with limited effective treatment options. This study explores the effectiveness of onabotulinumtoxinA (BtxA) as an adjunct therapeutic to TMJ arthroscopy in the relief of CME. METHODS A retrospective cohort study of patients receiving TMJ arthroscopy, with or without BtxA injections for CME, was conducted. Variables assessed include pain using a visual analog scale (VAS), maximal incisal opening (MIO), muscle soreness, and headache frequency and duration. RESULTS Sixty patients (44 BtxA, 16 Control), consisting of 56 (93.3%) females, met inclusion criteria. A significant reduction in pain is reported with patients receiving BtxA (p < 0.0001) on VAS as compared to Control group. BtxA treatment also significantly reduced headache frequency and duration (p < 0.05). CONCLUSION These results support the use of adjunctive BtxA treatment with arthroscopy for the treatment of CME in the context of TMD.

Abstract
OBJECTIVE The increasing wealth of clinical data may become unmanageable for a physician to assimilate into optimal decision-making without assistance. Utilizing a novel machine learning (ML) approach, we sought to develop algorithms to predict patient outcomes following the overactive bladder treatments OnabotulinumtoxinA (OBTX-A) injection and sacral neuromodulation (SNM). MATERIALS AND METHODS ROSETTA datasets for overactive bladder patients randomized to OBTX-A or SNM were obtained. Novel ML algorithms, using reproducing kernel techniques were developed and tasked to predict outcomes including treatment response and decrease in urge urinary incontinence episodes in both the OBTX-A and SNM cohorts, in validation and test sets. Blinded expert urologists also predicted outcomes. Receiver operating characteristic curves were generated and AUCs calculated for comparison to lines of ignorance and the expert urologists' predictions. RESULTS Trained algorithms demonstrated outstanding accuracy in predicting treatment response (OBTX-A: AUC 0.95; SNM: 0.88). Algorithms accurately predicted mean decrease in urge urinary incontinence episodes (MSE < 0.15) in OBTX-A and SNM. Algorithms were superior to human experts in response prediction for OBTX-A, and noninferior to human experts in response prediction for SNM. CONCLUSIONS Novel ML algorithms were accurate, superior to expert urologists in predicting OBTX-A outcomes, and noninferior to expert urologists in predicting SNM outcomes. Some aspects of the physician-patient interaction are subtle and uncomputable, and thus ML may complement, but not supplant, a physician's judgment.

Abstract
INTRODUCTION AND HYPOTHESIS The association between overactive bladder (OAB) syndrome and sexual dysfunction is well documented. Intra-detrusor onabotulinumtoxinA (Botox) has proven to be effective treatment for OAB syndrome. Our aim was to examine the impact of intravesical Botox injection on sexual function in patients with OAB, by systematically reviewing the literature. METHODS We reviewed the literature for studies that reported a change in sexual function after Botox treatment in patients suffering from OAB. This review was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement using pre-agreed keywords, from database inception to December 2020. Statistical analyses were performed using Review Manager (RevMan; v.5.4). RESULTS Initial results yielded 455 citations. Seven articles met our inclusion criteria. One article was double-reported, leaving 6 studies in the systematic review. Three observational before-and-after studies used the Female Sexual Function Index (FSFI) with sufficient information, and therefore were included in our meta-analysis. The pooled number of participants in all studies was 119 patients. In the meta-analysis, there was significant improvement in the following domains of the FSFI after Botox injection; desire (mean difference (MD) -0.51, p = 0.02), arousal (MD -0.86, p = 0.02), lubrication (MD -0.57, p = 0.03), orgasm (MD -0.65, p = 0.0003) and satisfaction (MD -0.46, p = 0.05). Pain was the only domain that did not show improvement (MD -0.07, p = 0.79). The total FSFI score was reported in 88 patients (two studies) showing significant improvement (MD -0.77, p = 0.006). CONCLUSIONS We report a systematic review of the effect of Botox treatment on sexual function in patients with OAB. Although studies are small, the results indicate a positive effect in patients with OAB.

Abstract
INTRODUCTION AND HYPOTHESIS We hypothesized that patients with refractory overactive bladder (rOAB) have similar improvement with percutaneous tibial nerve stimulation (PTNS) and OnabotulinumtoxinA (BTX). METHODS This multicenter cohort study compared BTX and PTNS in women with rOAB. Baseline information included Overactive Bladder Questionnaire (OABq) short form, Urinary Distress Inventory-6 (UDI-6), and voiding diary. Primary outcome was cure, defined as "very much better" or "much better" on the Patient Global Impression of Improvement (PGII) AND a reduction in OABq symptom severity scale (SSS) ≥10 at 3 months after treatment. Assuming 80% power to detect a ten-point difference in OABq-SSS, 80 participants were required per group. RESULTS A total of 150 patients were enrolled; 97 completed 3 months of therapy and were included. At baseline, BTX patients had more detrusor overactivity (70% vs 40%, p = 0.025), urgency incontinence (UUI; OABq-SSS#6 4 vs 3, p = 0.02, SSS 65 vs 56, p = 0.04), but similar health-related quality of life (HRQL 49 vs 54, p = 0.28), voids (7 vs 8, p = 0.13), and UUI episodes (2 vs 2, p = 1.0). At 3 months, cure rates were similar: BTX 50% vs PTNS 44.2% (p = 0.56). Both groups had improved SSS (-37 vs -29, p = 0.08) and HRQL (31 vs 24, p = 0.14). Patients receiving BTX had a greater improvement in urgency (ΔOABq-SSS#2-3 vs -2; p = 0.02) and UUI (ΔOABq-SSS#6-2 vs -1; p = 0.02). No characteristics were predictive of cure. CONCLUSIONS BTX resulted in significantly greater improvement in urgency and UUI than PTNS, but no difference in success based on PGII and OABq-SSS, which may be due to a lack of power.

Long Term Effectiveness and Safety of Intracavernosal Botulinum Toxin A as an Add-on Therapy to Phosphosdiesterase Type 5 Inhibitors or Prostaglandin E1 Injections for Erectile Dysfunction. J Sex Med 2022; 19:83-89. [PMID: 34937674 DOI: 10.1016/j.jsxm.2021.10.011] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/30/2021] [Revised: 10/29/2021] [Accepted: 10/31/2021] [Indexed: 01/23/2023]
Abstract
BACKGROUND Some evidence suggests that intracavernosal botulinum toxin A (BTX-A IC) injections administered in addition to phosphodiesterase type 5 inhibitors (PDE5-Is) or prostaglandin E1 intracavernosal injections (PGE1 ICI) could effectively treat erectile dysfunction (ED) in non-responders, or insufficient responders to these pharmacologic treatments. AIM To determine the long-term effectiveness and safety of combined treatment involving a single injection of BTX-A IC as an add on therapy to PDE5-Is or PGE1-ICI for the treatment of ED of different etiologies. METHODS A retrospective, uncontrolled, single center study was conducted. Data from 123 consecutive patients with ED who were insufficient responders to PDE5-Is or PGE1-ICI and who received onabotulinumtoxinA 100 U, abobotulinumtoxinA 250 U or 500 U IC as an add on to their current pharmacologic treatment were analyzed. All analyses were exploratory. Qualitative data were compared using the Fisher's exact test. Univariate and multivariate analysis were performed using logistic regression with Odds Ratios (OR). Only variables with P < .05 in the univariate analysis were selected for multivariate analysis. RESULTS The minimally clinically important difference (relative to baseline severity of ED) in the International Index of Erectile Function-Erectile function domain (IIEF-EF) score was achieved in 50% of patients at 34 (27-42) days and in 41% at 5.9 (3.9 - 8.1) months following BTX-A IC in combination with PDE5-Is or PGE1 ICI. The severity of ED influenced response to BTX-A IC according to the multivariate analysis (OR = 0.3, IC(95%]) = (0.16 - 0.56). Neither being post prostatectomy nor the type of BTX-A affected the response. Effectiveness tended to decrease more over time with abobotulinumtoxinA 250 U than 500 U.The only side-effects were mild penile pain on injection (n = 1) and mild penile pain for 3 days following injection (n = 1); no systemic effects were reported. CLINICAL IMPLICATIONS BTX-A IC (all types) administered as an add on to registered pharmacologic treatments improved erectile function for at least 6 months in 41% of patients with ED of varying etiologies, and was safe. STRENGTHS & LIMITATIONS A relatively large cohort of patients with ED was included, with a long follow-up period, however the study was retrospective, and uncontrolled. CONCLUSION This study provides preliminary evidence that BTX-A IC administered as an add-on therapy for ED that is insufficiently responsive to standard therapy is effective for at least 6 months, and is safe. Randomized clinical trials are now needed to fully confirm these results.

Abstract
INTRODUCTION Migraine is mostly a female disorder because of its lower prevalence in men. Less than 20% of patients included in the available studies on migraine treatments are men; hence, the evidence on migraine treatments might not apply to men. The aims of the present study were to provide reliable information on the effectiveness of onabotulinumtoxinA (BT-A) for chronic migraine in men and to compare clinical benefits between men and women. METHODS We performed a pooled patient-level gender-specific analysis of real-life data on BT-A for chronic migraine of patients followed-up to 9 months. We reported the 50% responder rates during each BT-A cycle, defined as percentage of reduction in monthly headache days (MHDs) compared to baseline, along with 75% and 30% responder rates. We also reported the mean decrease in MHDs and in days of acute medication use (DAMs) during each BT-A cycle as compared to baseline. We also evaluated the reasons for stopping the treatment within the third cycle. RESULTS We included an overall cohort of 2879 patients, 522 of whom (18.1%) were men. In men, 50% responder rates were 27.7% during the first BT-A cycle, 29.2% during the second, and 35.6% during the third cycle; in women, the corresponding rates were 26.6%, 33.5%, and 41.0%. In the overall cohort, responder rates did not differ between men and women during the first two cycles; during the third cycle, the distribution was different (P < 0.001) mostly because of higher rates of treatment stopping and non-responders in men. In the propensity score matched cohort, the trend was maintained but lost its statistical significance. Both men and women had a significant decrease in MHDs and in DAMs with BT-A treatment (P < 0.001). There were no gender differences in those changes with the only exception of MHD decrease which, during the third cycle, was lower in men than in women (7.4 vs 8.2 days, P = 0.016 in the overall cohort and 9.1 vs 12.5 days, P = 0.009 in the propensity score matched cohort). At the end of follow-up, 152 men and 485 women stopped BT-A treatment (29.1% vs 20.6%; P < 0.001). The relative proportion of patients stopping treatment because of inadequate response (less than 30% decrease in MHDs from baseline) was higher in men than in women (42.8% vs 39.6%), while the proportion of patients stopping because of adverse events was higher in women than in men (5.6% vs 0%; P = 0.031). CONCLUSIONS Our pooled analysis suggests that the response to BT-A is significant in both men and women with a small gender difference in favor of women. Men tended to stop the treatment more frequently than women. We emphasize the need for more gender-specific data on migraine treatments from randomized controlled trials and observational studies.

[PMID: 34523107 PMCID: PMC8586057 DOI: 10.1007/s40122-021-00316-2] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/05/2021] [Accepted: 09/01/2021] [Indexed: 11/06/2022] Open
Abstract
INTRODUCTION OnabotulinumtoxinA (OBT-A) is one of the most studied prophylactic treatments for chronic migraine. Large clinical trials, and now real-world studies, continue to provide evidence to support the use of OBT-A as an effective treatment to manage chronic migraine. The objective of this study was to explore patient experience and perception of prophylactic treatment with OBT-A for chronic migraine. METHODS Data were collected using semi-structured interviews using open-ended questions to uncover rich descriptive data on patient experiences. Interviews were transcribed and analysed using NVivo data analysis software to code and identify themes across the dataset. Three patient groups were included in the analysis: (1) patients who were receiving continued OBT-A treatment; (2) patients who discontinued OBT-A treatment; (3) patients who were recommended for OBT-A treatment but did not proceed. RESULTS For patients who received at least one OBT-A treatment, four main themes emerged, which described patients' expectations, experiences, and feelings towards their treatment decisions. Two main themes emerged that were common to patients, who had discontinued their treatment and those, who were recommended for OBT-A treatment but did not proceed, which were identified as potential barriers to initiate or continue prophylactic treatment with OBT-A. CONCLUSION Understanding patients' perspective is an important part of clinical practice and may impact on decision-making. Qualitative data can provide a more holistic view of patient care and treatment insights that may not be evaluated during a clinical trial. This study revealed potential barriers to treatment that can inform future policy and practice.

Abstract
INTRODUCTION The safety and efficacy of both abobotulinumtoxinA and onabotulinumtoxinA for upper limb spasticity are well established, but head-to-head comparisons are lacking. METHODS DIRECTION is an international, randomized, double-blind, crossover study comparing the safety and efficacy of abobotulinumtoxinA with onabotulinumtoxinA in the management of upper limb spasticity at doses at or near maximum recommended in product labelling. Participants (18-75 years) will be randomized (1:1) to either one cycle of abobotulinumtoxinA (900U) followed by onabotulinumtoxinA (360U) or vice versa. To maintain blinding, a fixed volume (3.6 ml) will be injected into the target upper limb muscles (four wrist and finger flexors and biceps brachii). The second treatment cycle will begin at Week 12 if retreatment criteria are fulfilled, and if not, they will be reassessed every 4 weeks until they meet retreatment parameters. PLANNED OUTCOMES The primary hypothesis is that there is comparable safety between products; non-inferiority will be tested based on treatment-emergent adverse event (TEAE) rates from injection to Week 12. A secondary hypothesis is that abobotulinumtoxinA has longer duration of effect than onabotulinumtoxinA. This hypothesis will be tested with secondary efficacy endpoints, including injection cycle duration, Modified Ashworth Scale, Disability Assessment Scale and Physician Global Assessment.

Abstract
Botulinum neurotoxins (BoNTs) are proteins produced by bacteria of the Clostridium family. Upon oral ingestion, BoNT causes the neuroparalytic syndrome botulism. There are seven serotypes of BoNT (serotypes A-G); BoNT-A and BoNT-B are the botulinum toxin serotypes utilized for therapeutic applications. Treatment with BoNT injections is used to manage chronic medical conditions across multiple indications. As with other biologic drugs, immunogenicity after long-term treatment with BoNT formulations may occur, and repeated use can elicit antibody formation leading to clinical nonresponsiveness. Thus, approaching BoNT treatment of chronic conditions with therapeutic formulations that minimize stimulating the host immune response while balancing patient responsiveness to therapy is ideal. Immunogenicity is a clinical limitation in many settings that use biologic drugs for treatment, and clinically relevant immunogenicity reduction has been achieved through engineering smaller protein constructs and reducing unnecessary formulation components. A similar approach has influenced the evolution of BoNT formulations. Three BoNT-A products and one BoNT-B product have been approved by the Food and Drug Administration (FDA) for therapeutic use: onabotulinumtoxinA, abobotulinumtoxinA, incobotulinumtoxinA, and rimabotulinumtoxinB; a fourth BoNT-A product, daxibotulinumtoxinA, is currently under regulatory review. Additionally, prabotulinumtoxinA is a BoNT-A product that has been approved for aesthetic indications but not therapeutic use. Here, we discuss the preclinical and clinical immunogenicity data that exist within the scientific literature and provide a perspective for considering immunogenicity as a key factor in choice of BoNT formulation.

Abstract
BACKGROUND We examined the efficacy and tolerability of calcitonin gene-related peptide-targeted monoclonal antibodies (CGRP-targeted mAbs) as add-on therapy for patients with chronic migraine (CM) undergoing treatment with onabotulinumtoxinA (onabot) who require additional preventive therapy. METHODS We reviewed medical records of patients with CM receiving treatment with onabot who were subsequently prescribed a CGRP-targeted mAb medication. The primary outcome was the change in number of monthly headache days (MHDs) reported. Secondary outcomes were change in headache pain severity, discontinuation due to lack of tolerability, and severe adverse events. RESULTS Of 153 patients, 111 (72.5%) reported a decrease in either MHDs or headache pain severity, with documentation of MHDs in 66 patients. Among these 66 patients, the average number of MHDs before initiation of onabot treatment was 25.7. After onabot treatment, an average decrease of 10.9 MHDs was reported (P < 0.001). After the addition of a CGRP-targeted mAb medication, patients experienced a further decrease of 5.7 MHDs (P < 0.001). With combined therapy, patients reported a total decrease of 16.6 MHDs (P < 0.001). Adverse effects occurred in 13 patients (8.5%) after addition of the CGRP-targeted mAb and included constipation, injection site reaction, and fatigue. No serious adverse events were reported. CONCLUSION Adding a CGRP-targeted mAb to onabot in patients with CM was associated with further reductions in MHDs without major tolerability issues across a range of mAbs. This retrospective review supports the conduct of a well-designed double-blind study adding a CGRP-targeted mAb or placebo to onabot.

Abstract
CONTEXT Individuals with spinal cord injury (SCI) suffering from autonomic dysreflexia (AD) due to neurogenic detrusor overactivity (NDO) can effectively be treated with intradetrusor onabotulinumtoxinA. We present a complex case to highlight the treatment's potential limitations to ameliorate AD and improve lower urinary tract (LUT) function in this population. FINDINGS A 46-year old man, who was relying on an indwelling urethral catheter for bladder emptying due to severely impaired hand function following a SCI (C5, AIS B) sustained 30 years ago, underwent intradetrusor onabotulinumtoxinA injections for treatment of refractory NDO and associated AD. Although LUT function slightly improved (i.e. cystometric capacity increased while detrusor pressure was reduced), severe bladder-related AD persisted post-treatment. CONCLUSIONS This case raises awareness of serious considerations when treating NDO-related AD in individuals with longstanding neurogenic LUT dysfunction and compromised dexterity following SCI. Given the limited improvement in LUT function and persisting bladder-related AD following treatment, urinary diversion as advocated in the wider literature should be considered to protect an individual's urinary tract from further deterioration and thus eliminate bladder-related AD consequences long-term. Early treatment and management of NDO and AD is crucial to minimize complications associated with these two major health risks in this population.

Abstract
BACKGROUND OnabotulinumtoxinA is a novel therapeutic intervention whose mechanism of action is believed to modify the negative facial feedback, thus abating symptoms of depression. This putative new antidepressant agent offers minimal systemic side effects and negligible risk of pharmacological interactions. We set out to examine the evidence for the use of onabotulinumtoxinA in major depression. METHODS A systematic search of the literature identified double-blind randomised controlled trials (RCTs) investigating the use of onabotulinumtoxinA in the treatment of major depression versus placebo. Data, reported according to the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA), was combined in meta-analyses (PROSPERO registration ID: CRD42020183538). RESULTS The search identified five RCTs (four double-blind) comparing onabotulinumtoxinA to placebo. OnabotulinumtoxinA was more effective than placebo when administered within the 20-40 IU dose range in double-blind RCTs. The analysis was free of publication bias and significantly heterogeneous. Meta-regression analyses indicated that onabotulinumtoxinA was more efficacious in women and in higher doses in female patients and less effective with polypharmacy, especially when an increasing number of antidepressants were prescribed. The effectiveness of onabotulinumtoxinA was higher in more recently published double-blind RCTs. CONCLUSION The meta-analysis supports the efficacy of the intervention with the results being highly heterogeneous across studies. In view of the heterogeneity of the findings and the significant moderators of benefit (sex, year of study completion and the interaction between sex and dose), more research is required to better understand the role of onabotulinumtoxinA in the treatment of depression.

Efficacy and safety of onabotulinumtoxinA in patients with overactive bladder: subgroup analyses by sex and by serum prostate-specific antigen levels in men from a randomized controlled trial. Int Urol Nephrol 2021; 53:2243-2250. [PMID: 34292493 PMCID: PMC8494701 DOI: 10.1007/s11255-021-02962-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/18/2021] [Accepted: 07/13/2021] [Indexed: 11/29/2022]
Abstract
Purpose We aimed to assess onabotulinumtoxinA treatment outcomes by sex in patients with overactive bladder (OAB) and then explore the impact of serum prostate-specific antigen (PSA) levels in men. Methods Patients inadequately managed with OAB medications were randomized to receive single-dose onabotulinumtoxinA (100 U) or placebo intravesical injection in a phase III trial in Japan. We performed subgroup analyses by sex and post-hoc subgroup analyses using male PSA categories. Results In women (n = 186), onabotulinumtoxinA demonstrated statistically significant and clinically relevant improvements in all urinary symptoms at Week 12. In men with lower PSA (< 1.5 ng/mL, n = 40), onabotulinumtoxinA also showed numerically greater reductions in urinary symptom frequency than placebo; the between-group differences (onabotulinumtoxinA minus placebo) in change from baseline in the average daily number at Week 12 for urinary incontinence (UI), urgency UI, micturition, urgency, and nocturia were − 1.43, − 1.79, − 2.81, − 2.45, and − 0.32 episodes, respectively. In men with higher PSA (≥ 1.5 ng/mL, n = 22), onabotulinumtoxinA did not reduce urinary symptom frequency. Some patients treated with onabotulinumtoxinA showed elevated post-void residual urine volume at Week 2 (≥ 200 mL): 4 of 91 women, none of the men with lower PSA and 3 of 11 men with higher PSA. Conclusions OnabotulinumtoxinA was efficacious and well tolerated in women and in men with lower PSA levels. Given our post-hoc subgroup analyses which suggested that onabotulinumtoxinA treatment is a good treatment option for OAB males with lower PSA levels, future studies having prostate volume data with larger sample size are warranted to verify our findings.

Abstract
There is no available data on the journey of dystonia patients once referred to a tertiary center to undergo deep brain stimulation (DBS). We hypothesized that some patients might be incorrectly diagnosed while others might decline the procedure or experience significant benefit with switching to a different botulinum neurotoxin (BoNT). This is a single-center, retrospective study of dystonia patients who were referred to the DBS program between January 2014 and December 2018. We collected data on the surgical decision as well as factors influencing this decision. Sixty-seven patients were included (30 males, mean age: 48.3 ± 20.1 years, disease duration: 16.9 ± 15.3 years). Thirty-three (49%) patients underwent DBS. Four (6%) patients were awaiting the procedure while the remaining 30 patients (45%) did not undergo DBS. Reasons for DBS decline were patient refusal (17, 53%), functional dystonia (6, 20%), and successful use of AbobotulinumtoxinA (3, 10%) in patients who had failed other BoNTs. Our study highlights the importance of structured patient education to increase acceptance of DBS, as well as careful patient evaluation, particularly with respect to functional dystonia. Finally, changing BoNT formulation might be beneficial in some patients.

Abstract
OBJECTIVE To determine whether erenumab is effective and safe in refractory chronic migraine with medication overuse headache. METHODS In this prospective, multicentric, real-life study, chronic migraine with medication overuse headache patients who received erenumab were recruited. Study inclusion was limited to patients who previously failed onabotulinumtoxinA in addition to at least three other pharmacological commonly used migraine preventive medication classes. RESULTS Of 396 patients who received erenumab, 38% (n = 149) met inclusion criteria. After 3 months, 51% (n = 76) and 20% (n = 30) patients achieved ≥ 50% and ≥ 75% reduction in monthly headache days, respectively. Monthly pain medications intake decreased from 46.1 ± 35.3 to 16.8 ± 13.9 (p < 0.001), while monthly headache days decreased from 25.4 ± 5.4 to 14.1 ± 8.6 (p < 0.001). Increasing efficacy of erenumab over the study period was observed. Allodynia was a negative predictive factor of erenumab response (odds ratio = 0.47; p = 0.03). Clinical conversion to episodic migraine with no medication overuse was observed in 64% (n = 96) patients. No serious adverse events were observed. CONCLUSIONS Erenumab reduced significantly migraine frequency and pain medication intake in refractory chronic migraine with MOH patients.

Abstract
Background Chronic migraine (CM) is associated with substantial economic burden. Real-world data suggests that onabotulinumtoxinA treatment for CM reduces healthcare resource utilisation (HRU) and related costs. Methods REPOSE was a 2-year prospective, multicentre, non-interventional, observational study to describe the real-world use of onabotulinumtoxinA in adult patients with CM. This analysis examined the impact of onabotulinumtoxinA on HRU. Patients received onabotulinumtoxinA treatment approximately every 12 weeks according to their physicians’ discretion, guided by the summary of product characteristics (SPC) and PREEMPT injection paradigm. HRU outcome measures were collected at baseline and all administration visits and included headache-related hospitalizations and healthcare professional (HCP) visits. Health economic data, including family doctor and specialist visits, inpatient treatment for headache, acupuncture, technical diagnostics, use of nonpharmacologic remedies, and work productivity were also collected for patients enrolled at German study centres. Results Overall, 641 patients were enrolled at 78 study centres across 7 countries (Germany, UK, Italy, Spain, Norway, Sweden, and Russia), 633 received ≥1 onabotulinumtoxinA dose, and 128 completed the 2-year study. Patients were, on average, aged 45 years, 85% were female, and 60% (n = 377) were from Germany. At the end of the 2-year observation period, significantly fewer patients reported headache-related hospitalizations (p < 0.02) and HCP visits (p < 0.001) within the past 3 months than in the 3 months before baseline. In the German population, reductions were observed across all health services at all follow-up visits compared with baseline. The percentage of patients who saw a family doctor decreased from 41.7% at baseline to 13.5% at administration visit 8 and visits to a medical specialist decreased from 61.7% to 5.2% of patients. Inpatient acute treatment and technical diagnostics declined from 6.4% and 19.7% of patients at baseline to 0.0% and 1.0% at administration 8, respectively. The use of nonpharmacologic remedies and medication for the acute treatment of migraine also decreased with continued onabotulinumtoxinA treatment. Work incapacity, disability, absenteeism, and impaired performance at school/work improved with onabotulinumtoxinA treatment for CM over the 2-year observation period. Conclusions Real-world evidence from REPOSE demonstrates that onabotulinumtoxinA treatment is associated with decreased HRU and supports the long-term benefits associated with the use of onabotulinumtoxinA for CM in clinical practice. Trial registration NCT01686581. Name of registry: ClinicalTrials.gov. URL of registry: Date of retrospective registration: September 18, 2012. Date of enrolment of first patient: July 23, 2012.

Abstract
Background There is currently a wide therapeutic arsenal for migraine patients, without a single first-line preventive drug and we choose the different available alternatives taking into account comorbidities, national guidelines, previous treatments and personal experiences. Our objective was to evaluate the differences in the use of migraine treatments between neurologists from different countries. Methods This is a multi-centre observational study carried out by neurologists from specialized headache units in seven countries, retrospective with consecutive inclusion of all patients presenting with a migraine diagnosis, over a period of three months. Results A total of 734 patients were recruited but only 600 were considered in the analysis in order to homogenize the patient cohorts from countries: 200 Spain (ES), 100 Italy (IT), 85 Russia (RUS), 80 Germany (DE), 60 Portugal (PT), 45 Poland (PL) and 30 Australia (AU). 85.4 % of patients were women with a mean age of 42.6 ± 11.8 years. Considering previous and current preventive treatment, the order of use was: antidepressants (69.3 %), antiepileptic drugs (54.7 %), beta-blockers and antihypertensive drugs (49.7 %), OnabotulinumtoxinA (44.0 %) and others (36.2 %). Statistically significant differences were found between all pharmacological classes: antidepressants were commonly used in all countries, with the exception of Poland (AU: 76.7 %, IT: 71.0 %, DE: 60.0 %, PL: 31.1 %, PT: 71.7 %, RUS: 70.6 %, ES: 78.5 %; p < 0.0001); antiepileptic drugs were more frequently prescribed in Portugal, Australia and Spain (AU: 73.3 %, IT: 40.0 %, DE: 37.5 %, PL: 48.9 %, PT: 85.0 %, RUS: 29.4 % and ES: 69.0 %; p < 0.0001); beta-blockers and antihypertensive drugs were frequently used in all countries except Italy (AU: 60.0 %, IT: 14.0 %, DE: 53.8 %, PL: 48.9 %, PT: 68.3 %, RUS: 49.4 % and ES: 59.0 %; p < 0.0001); BTX-A were predominately used in Spain, Italy and Australia (AU:56.7 %, IT:58.0 %, DE:20.0 %, PL: 42.2 %, PT: 26.7 %, RUS: 24.7 % and ES: 58.5 %; p < 0.0001) and others were most frequently used in Poland (AU: 0.0 %, IT: 19.0 %, DE: 42.5 %, PL: 95.6 %, PT: 31.7 %, RUS: 3.5 % and ES: 49.5 %; p < 0.0001). If only patients without comorbidities are considered (200/600), statistically differences between countries persist in all preventive treatments. Conclusions There is heterogeneity in the choice of preventive treatment between different countries. Prospective comparative studies of the different oral and subcutaneous alternatives would help to create a global therapeutic algorithm that would guarantee the best option for our patients.

Abstract
OBJECTIVE Linear headache has been recently described as an episodic or chronic unilateral pain distributed along a fixed linear trajectory, which combines some characteristics of epicrania fugax and nummular headache. The aim of this study was to describe the clinical characteristics and therapeutic response of a series of 16 new patients. DESIGN This is an observational study with a series of cases. SETTING The study period encompassed June 2014 to June 2019. Demographic, clinical, and therapeutic response data were recorded. METHODS We included all consecutive patients who presented pain with the following characteristics: sharply contoured, fixed in size and shape, with linear shape, without movement along a trajectory, and not circumscribed to the territory of any nerve. RESULTS Twelve patients were women, and four were men. The mean age at onset was 40.1 years. Pain was described as pressing in seven patients, burning in five, and electric or stabbing in two each. Symptomatic treatment had been used by 13 patients (81.2%), with analgesics being the most frequent treatment used. Thirteen patients received preventive treatment. The response to oral medications and anesthetic blockade was insufficient. OnabotulinumtoxinA was used in six cases, with an optimal (>75%) response observed in half. CONCLUSION Linear headache appears to be a distinct headache syndrome from epicrania fugax or nummular headache. Preventive treatment is often required. The drug with the best response was onabotulinumtoxinA.
