The Impact of SARS-CoV-2 Pandemic Lockdown on a Botulinum Toxin Outpatient Clinic in Germany.

Botulinum neurotoxin type A (BoNT/A) injections have to be administered repeatedly to achieve a rather stable, high level of improvement. This study aimed to take a look at changes in the daily routine of a BoNT/A outpatient clinic due to the SARS-CoV-2 pandemic lockdown, analyze the impact of SARS-CoV-2-induced re-injection delay on outcomes in patients with cervical dystonia (CD) (n = 36) and four other disease entities (n = 58), and study the influence of covariables, including previous injections and doses. For the present observational study, the first 100 patients who were scheduled to have an appointment between April 20 and May 18 during the partial lockdown and also had been treated regularly before the lockdown were recruited. Clinical and demographical characteristics and treatment-related data from the previous visits were extracted from charts. Time delay, symptom severity assessment, and TSUI score (if applicable) were gathered at the first coronavirus pandemic lockdown emergency visit for each patient. Of the 94 patients who could come to the clinic, 48 reported a delay and 44 reported worsening during the delay. Delays ranged from 1 to 63 days, the mean delay was 23 days, and the mean worsening was 26% compared to the previous visit. A significant correlation was found between the duration of the delay and the patient's rating of worsening (PwP). In CD patients, the physician´s rating of CD worsening by the TSUI score (ATUSI-PTSUI) was significantly correlated with general worsening (DwP) and the TSUI at the last visit (PTSUI). A small delay of a few weeks led to a similar worsening of symptoms in CD and all other disease entities and to relapse on a higher level of severity. This relapse can only be compensated by continuous treatment up to at least 1 year until patients reach the same level of treatment efficacy as that before the SARS-CoV-2 pandemic.

A risk-stratified approach toward safely resuming OnabotulinumtoxinA injections based on dosing and ambulatory status in pediatric patients with cerebral palsy during the Coronavirus pandemic of 2019 (COVID-19).

PURPOSE: After the onset of the Coronavirus pandemic of 2019-2020 (COVID-19), physicians who inject OnabotulinumtoxinA (BoNT-A) were left with determining risks and benefits in pediatric patients with cerebral palsy. Many of these patients have pre-existing conditions that make them more prone to COVID-19 symptoms, and this susceptibility potentially increases after BoNT-A injections. METHODS: A retrospective chart review of 500 patients identified 256 pediatric patients with cerebral palsy who received an intramuscular BoNT-A injection to determine relative doses used for each Gross Motor Functional Classification Score (GMFCS). Data regarding age, weight, GMFCS, BoNT-A total body dosage, and inpatient hospitalizations for 6 months post-injection were collected. Differences between GMFCS levels were analyzed using one-way analysis of variance testing. Inpatient hospitalizations were recorded and assessed using relative risk to determine the population risk of hospitalization in the setting of initiating injections during the COVID-19 pandemic. RESULTS: Based on GMFCS level, patients who were GMFCS I or II received fewer units of BoNT-A medication per kilogram of body weight compared to GMFCS III-V (p< 0.0005, F= 25.38). There was no statistically significant difference in frequency or time to hospitalization when comparing patients receiving BoNT-A compared to a control group. CONCLUSIONS: Resumption of BoNT-A injections during the time of COVID-19 requires a systematic approach based on risks and potential benefits. Data from this analysis does not show increased risk for patients who received injections historically; however, recommendations for resumption of injections has not previously been proposed in the setting of a pandemic. In this manuscript, a tiered approach to considerations for injections was proposed. Botulinum toxin type A injections have a history of improving spasticity in the pediatric patient with cerebral palsy. Ensuring appropriate selection of patients for injection with BoNT-A during this pandemic is increasingly important.

Botulinum toxin therapy in the SARS-CoV-2 pandemic: patient perceptions from a German cohort.

The SARS-CoV-2 virus pandemic has provoked drastic countermeasures including shutdowns of public services. We wanted to describe the effects of a 6 week shutdown of a large German botulinum toxin (BT) outpatient clinics on patients and their well-being. 45 patients (age 61.9 ± 9.8 years, 29 females, 16 males) receiving BT therapy (319.3 ± 201.9MU-equivalent, treatment duration 8.3 ± 5.5 years) were surveyed with a standardised questionnaire. The shutdown delayed BT therapy by 6.6 ± 2.3 weeks. 93% of the patients noticed increased muscle cramps and 82% increased pain reducing their quality of life by 40.2 ± 19.5%. For 23 patients with cervical dystonia this reduction was 41.1 ± 18.3%, for 3 patients with blepharospasm 33.3 ± 15.3%, for 9 patients with spasticity 37.8 ± 15.6%, for 4 patients with pain conditions 37.4 ± 35.7% and for 3 patients with hemifacial spasm 27.5 ± 17.1%. After the shutdown 66% of patients perceived BT therapy as more important than before, 32% perceived it as unchanged. For all patients long-term availability of BT therapy was very important or important. 98% of the patients perceived the shutdown as inadequate and felt their patient rights not respected. The shutdown confirmed the considerable burden of disease caused by dystonia, spasticity, hemifacial spasm and various pain conditions and the importance of BT therapy to treat them. Any shutdown severely affects these patients and needs to be avoided.

Delay in OnabotulinumtoxinA Treatment During the COVID-19 Pandemic-Perspectives from a Virus Hotspot.

The COVID-19 pandemic has undoubtedly changed our practice of medicine. With our collective resources and attention focused on caring for those afflicted with the disease, other medical conditions have temporarily but understandably faced constraint. For migraine patients who often require in-person visits for infusions and procedures, this has become particularly challenging. Here, we share our experience in navigating this exigency amidst a local surge of COVID-19.
