OBJECTIVES: Limited data are available regarding the occurrence and the extent of cardiac rhythm disturbances in patients with COVID-19 treated with Remdesivir. METHODS: We present a case series of 52 patients who underwent daily electrocardiogram (ECG) examination after Remdesivir administration. RESULTS: Compared to baseline, a significant heart rate reduction was observed after initiation of Remdesivir; however, no case of severe bradycardia or arrhythmias leading to significant clinical complications or Remdesivir discontinuation occurred. Heart rate reduction was proportional to baseline heart rate values (r=0.75, p<0.001). By multivariate analysis, a less severe clinical presentation of Covid-19 (beta=0.47, p<0.01) was related to lower heart rate levels observed after Remdesivir administration. CONCLUSIONS: Despite a significant reduction in heart rate observed after Remdesivir administration, no severe cardiovascular toxicity was observed in Covid-19 patients, even in the case of cardiovascular comorbidities.

The aim of this study is to describe the features, the outcomes, and the clinical issues related to Remdesivir administration of a cohort of 220 patients (pts) with COVID-19 hospitalized throughout the last two pandemic waves in Italy. One hundred and nine pts were enrolled from 1 September 2020, to 28 February 2021 (Group A) and 111 from 1 March to 30 September 2021 (Group B). Notably, no differences were reported between the two groups neither in the timing of hospitalization. nor in the timing of Remdesivir administration from symptoms onset. Remarkably, a higher proportion of pts with severe COVID-19 was observed in Group B (25% vs. 10%, p < 0.001). At univariate and multivariate analysis, rather than the timing of Remdesivir administration, age, presence of coexisting conditions, D-dimers, and O2 flow at admission correlated positively to progression to non-invasive ventilation, especially for patients in Group B. However, the rate of admission in the Intensive Care Unit and/or death was comparable in the two groups (7% vs. 4%). Negligible variations in serum GOT, GPT, GGT, and eGFR levels were detected. A mean reduction in heart rate was noticed within the first three days of antiviral treatment (p < 0.001). Low rate of ICU admission, high rate of clinical recovery, and good drug safety were observed in COVID-19 patients treated with Remdesivir during two diverse pandemic waves.

Post-infectious/immune mediated effects of COVID-19 infection include descriptions of Guillain-Barré syndrome (GBS) in patients usually with respiratory failure and after 1-2 weeks from the onset of viral illness. Asymptomatic cases for COVID-19 infection were rarely described. Herein, we studied a 62-year-old patient with progressive weakness of lower extremities, rapidly evolving to a severe, flaccid tetraplegia and dysphagia. Neurological symptoms weren't preceded by fever or pulmonary symptoms. Because of laboratory test abnormalities (thrombocytopenia, lymphocytopenia, high inflammation indexes), the patient underwent to nasopharyngeal swab, resulted positive for SARS-CoV-2 on RT-PCR assay; cerebrospinal fluid (CSF) was negative for SARS-CoV-2. The clinical (severe symmetric distal upper and lower limbs weakness, grade 0/5; decreased proprioceptive sensitivity and hypoesthesia involving the four limbs; loss of deep tendon reflexes), electrophysiological (prevailing axonal polyradiculoneuritis) and CSF features (albumino-cytological dissociation) disclosed the GBS diagnosis (level 1 of diagnostic certainty according to the Brighton criteria). The patient received plasma exchange and immunoglobulin, and, at 4 weeks after treatment and physical therapy, the patient had moderate improvement (weakness at lower and upper extremities was grade 2/5 and 3/5, respectively). Neurologists and clinicians should be aware of the possible link between neurological symptoms and COVID-19 infection, not only after viral prodrome and pulmonary symptoms, but also without COVID-19 symptoms.
