Post-vaccination adverse reactions have been reported with varying symptoms and severity owing to research and production time pressures during the coronavirus disease 2019 (COVID-19) pandemic. In this article, we report a rare case of Guillain–Barré syndrome (GBS) in a patient with COVID-19 with acute respiratory distress syndrome (ARDS) after receiving Sinopharm's Vero Cell vaccine (China). The patient who was initially negative for COVID-19 was diagnosed with GBS based on paralysis that developed from the lower extremities to the upper extremities, as confirmed by cytoalbuminologic dissociation in the cerebrospinal fluid. The patient's condition worsened with ARDS caused by COVID-19 infection during the hospital stay, and SpO 2 decreased to 83% while receiving oxygen through a non-rebreather mask (15 l/min) on day 6. The patient was treated with standard therapy for severe COVID-19, invasive mechanical ventilation, and five cycles of therapeutic plasma exchange (TPE) with 5% albumin replacement on day 11 due to severe progression. The patient was weaned off the ventilator on day 28, discharged on day 42, and was completely healthy after 6 months without any neurological sequelae until now. Our report showed the potential of TPE for GBS treatment in critically ill patients with COVID-19 after COVID-19 vaccination.

Since the first case of Guillain-Barré syndrome (GBS)-associated SARS-CoV-2 (COVID-19) infection reported in 2020, a series of cases have been published in some countries. In this case report, we present a young patient with GBS, whose clinical and laboratory data were appropriate for the diagnosis of GBS due to COVID-19 infection. Neurological examination revealed the muscular weakness of lower limbs with Medical Research Council (MRC) scale of 2/5 associated with diminished reflexes. Laboratory studies showed the positive nasal swab RT-PCR test for COVID-19, leukopenia, increased ferritin and LDH levels, normal electrolyte and liver and kidney function, and normal chest X-ray. The result of cerebrospinal fluid showed the albuminocytologic dissociation. The patient was treated with remdesivir, dexamethasone, anticoagulation, and therapeutic plasma exchange (TPE). Patient's muscle weakness was significantly improved after 1 week of admission. He was discharged at 23rd days of hospitalization and followed-up in the out-patients department.

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic has been an alarming situation worldwide for the past 2 years. The symptoms of coronavirus disease 2019 (COVID-19) are not only confined to the respiratory system but also affect a multitude of organ systems. Bradycardia associated with Guillain-Barré syndrome (GBS) is a rare autonomic and peripheral neurological complication of COVID-19. In this case report, we present the case of a 26-year-old man diagnosed with bradycardia associated with GBS after contracting COVID-19. Initially, this patient had the classical symptoms of COVID-19 and was hospitalized in the intensive care unit (ICU) for acute respiratory distress syndrome (ARDS). Then, he developed weakness in the lower extremities, diminished tendon reflexes, a loss of sensation without sphincter muscle disorders, and bradycardia. His bradycardia did not respond to atropine. The patient was treated concurrently with a high-flow nasal cannula, systemic corticosteroids, anticoagulation, and therapeutic plasma exchange (TPE) for COVID-19-induced ARDS, bradycardia, and GBS. His ARDS and bradycardia improved after the first cycle of TPE and medical treatment. After three cycles of TPE, the patient progressively recovered his muscle strength in the lower limbs and regained peripheral sensation. He was discharged from the hospital in stable condition after 4 weeks of hospitalization and was followed up after 6 months for cardiorespiratory and neurological complications. This case report elucidates the potential difficulties and challenges that physicians may encounter in diagnosing and treating COVID-19-induced bradycardia and GBS during the pandemic outbreak. However, the patient outcomes with the treatment combining the conventional treatment with therapeutic plasma exchange seem to be optimistic.
