All reported GBS cases (n = 72) except two were symptomatic for COVID-19 with various severity. Most common manifestations of COVID-19 included fever (73.6%, 53/72), cough (72.2%, 52/72), dyspnea and/or pneumonia (63.8%, 46/72), hypo-/ageusia (22.2%, 16/72), hypo-/anosmia (20.8%, 15/72), and diarrhea (18.1%, 13/72). One of the two asymptomatic subjects never developed fever, respiratory symptoms, or pneumonia [10], whereas the other patient showed an asymptomatic pneumonia at chest computed tomography (CT) [12]. In all but six patients with available data [22, 24, 36, 44, 45, 52], SARS-CoV-2 RT-PCR with naso- or oropharyngeal swab or fecal exam was positive at first or following tests. Nevertheless, these six patients tested positive at SARS-CoV-2 serology. In four patients, the laboratory exam for the diagnostic confirmation was not specified [20, 40]. Typical “ground glass” aspects at chest-CT or similar findings at CT, Magnetic Resonance Imaging (MRI) or X-ray compatible with COVID-19 interstitial pneumonia were reported in 40 cases. The detailed therapies for COVID-19 are described in Table 1.
