Tolerability and outcomes with rollout of tixagevimab-cilgavimab in patients with common variable immunodeficiency.

Background: Tixagevimab-cilgavimab is a combination of 2 mAbs against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). In December 2021, the Food and Drug Administration issued Emergency Use Authorization for intramuscular injection of tixagevimab-cilgavimab for prophylaxis against SARS-CoV-2 in immunocompromised patients. Shortly thereafter, our clinic distributed tixagevimab-cilgavimab to patients with common variable immunodeficiency. Objective: We sought to evaluate the effectiveness and tolerability of tixagevimab-cilgavimab in a common variable immunodeficiency clinic. Methods: A retrospective chart review from February 1, 2022, to August 1, 2022, of 47 patients with common variable immunodeficiency who were offered tixagevimab-cilgavimab was carried out. Comparative outcomes of treatment and nontreatment groups examined the occurrence of SARS-CoV-2 infection, severity of SARS-CoV-2 infection, and other non-SARS-CoV-2 infections. Results: Seventy percent of the patients were female; mean age was 49 years. Twenty-three patients received tixagevimab-cilgavimab, and 24 did not receive prophylaxis. In the tixagevimab-cilgavimab group, all were vaccinated for SARS-CoV-2 and 22 were receiving immunoglobulin replacement. One patient was infected with SARS-CoV-2, no patients required emergency care, and 7 patients had non-SARS-CoV-2 infection. In the cohort that did not receive prophylaxis, 21 were vaccinated, and all received immunoglobulin replacement. Two patients tested positive for SARS-CoV-2, 1 patient required emergency care due to SARS-CoV-2 disease severity, and 4 patients had a non-SARS-CoV-2 infection. None of the results showed statistical significance. Conclusions: Although there is evidence that tixagevimab-cilgavimab can be protective against SARS-CoV-2 in immunocompromised individuals, our data suggest that this benefit may be blunted in patients with common variable immunodeficiency on immunoglobulin replacement. The additional benefit of tixagevimab-cilgavimab in immunocompromised patients already receiving replacement therapy requires further exploration.

Use of Integrative, Complementary, and Alternative Medicine in Children with Epilepsy: A Global Scoping Review.

(1) Background: Epilepsy is one of the most common chronic neurological disorders in childhood. Complementary and alternative medicine (CAM) use is highly prevalent in patients with epilepsy. Despite CAM's widespread and increasing popularity, its prevalence, forms, perceived benefits, and potential risks in pediatric epilepsy are rarely explored. (2) Methods: We performed a scoping review of the available literature on the use of CAM in pediatric epilepsy. (3) Results: Overall, global cross-sectional studies showed a variable degree of CAM usage among children with epilepsy, ranging from 13 to 44% in prevalence. Popular types of CAMs reported were supplements, cannabis products, aromatherapy, herbal remedies, dietary therapy, massage therapy, and prayer. Families often report that CAM is effective, although there are limited objective measures of this. Potential risks lie in the use of CAM, such as herbal remedies, and/or unregulated, contaminated, or unpurified products. Studies also underscored inadequate patient-physician discussions regarding CAM. (4) Conclusions: A better understanding of this topic would aid clinicians in guiding patients/families on the use of CAM. Further studies on the efficacy of the different types of CAM used, as well as potential side effects and drug interactions are needed.
