fluvoxamine and Autism-Spectrum-Disorder

The ongoing coronavirus disease 2019 (COVID-19) pandemic caused by the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) accelerates the discovery of prophylactic and therapeutic drugs for persons infected with the virus. Drug repurposing for the COVID-19 pandemic has received particular attention. Increasing clinical data suggest that antidepressant use in early-stage subjects with COVID-19 might be associated with a reduced risk of intubation or death. Among the antidepressants, fluvoxamine is the most attractive drug for mild to moderate subjects with COVID-19. In this article, we review the mechanisms of action (i.e., serotonin transporter, sigma-1 receptor, and acid sphingomyelinase) of fluvoxamine for COVID-19. Furthermore, we discuss a possible link between maternal COVID-19 infection and a risk for neuropsychiatric disorders (i.e., autism spectrum disorder and schizophrenia) in offspring.

Autism spectrum disorder (ASD) is characterized by impaired social communication and restricted repetitive behaviors and interests. There are no FDA-approved medications for these core symptoms, and there are limited data regarding pharmacological management of ASD in adults. Here, the literature was reviewed in an effort to develop an algorithm for pharmacological management of core symptoms of ASD in adults. The literature search was conducted using PubMed. It was very difficult to distil a plausible algorithm from these data. Not included in this review are behavioral strategies, which are first-line. For instances when medication is being considered for management of core ASD symptoms in adults, the authors suggest starting with fluvoxamine as first-line, with possible consideration of a second SSRI trial if there is an inadequate or no response to fluvoxamine. The next step, if there is comorbid irritability, is to consider a second-generation antipsychotic. If there is no comorbid irritability, in the final step of the tentative algorithm, there are possible augmenting agents: propranolol, memantine, d-cycloserine, and oxytocin. Management of the symptoms of ASD requires a comprehensive treatment approach, and treatment planning must be individualized. Treatment of core ASD symptoms is not always desired. Further studies are needed to develop a stronger evidence base to support pharmacological management of core symptoms.
