Novel outbreaks with COVID-19 can cause multiple systemic manifestations, including autoimmune disease. Among all the infections, respiratory complications are the most apparent symptoms. Guillain-Barre syndrome (GBS) is an acute immune-mediated polyradiculoneuropathy often related to previous infectious exposure. GBS emerged as a potentially severe complication of coronavirus disease 2019 (COVID-19) since its declaration as a global pandemic. We report the first case of COVID-19-induced acute motor axonal neuropathy variant of Guillain-Barre syndrome (GBS) from New York, USA. Our patient was a 66-year-old woman who had recently tested positive for COVID-19 and presented with bilateral upper and lower extremity weakness. Electromyogram studies showed acute demyelinating polyradiculoneuropathy. She was diagnosed with an acute motor axonal neuropathy variant of GBS. She was successfully treated with intravenous immunoglobulins (IVIGs) with marked improvement. In six months, she regained her strength back to normal. Whether GBS incidence in COVID-positive patients is based on molecular mimicry or anti-ganglioside antibodies is unclear. Physicians should be aware of GBS as a potentially serious complication associated with COVID-19. Further investigations and trials should be conducted better to understand the mechanism of GBS in patients of COVID-19.

On December 31, 2019, a novel coronavirus (COVID-19) was detected in Wuhan City, Hubei Province of the People's Republic of China [1] . COVID-19 is a new beta coronavirus, which acts via fusion with the angiotensin-converting enzyme 2 (ACE2) receptor [2] . COVID-19 viruses are emerging as a multisystem and autoimmune disease [3] . The first series of patients reported in December 2019 were typically diagnosed with a pneumonia-like presentation. The most common clinical symptoms were fever, cough, dyspnea, myalgia, headache, and diarrhea [4] . It can invariably affect the multisystem organs and trigger the autoimmune phenomenon [3, 4] . Several neurological manifestations have been associated with this disease. These manifestations involved both the central and peripheral nervous systems [5] .

There are emerging cases of COVID-19-induced neuropathy and Guillain-Barre syndrome (GBS) reported worldwide [6] . That correlation can be considered a direct effect of the virus on the nervous system or postinfectious immune-mediated response. GBS is acute immune-mediated polyneuropathy with several variant forms. GBS is marked by ascending motor impairment, mild to severe sensory disturbances, cranial nerve involvement, autonomic symptoms, and muscle or radicular pain. It is thought to be due to the molecular mimicry phenomenon, usually preceding infection best understood with Campylobacter jejuni related GBS. The most associated organisms are Campylobacter jejuni, cytomegalovirus, Epstein-Barr virus, human immunodeficiency virus (HIV), and Zika virus. This report describes GBS symptoms in one infected patient with COVID-19, seen for the first time in New York, USA. the neurological exam. On chest examination, she had bilateral rhonchi with decreased air entry. She denied the use of cigarettes, alcohol, or other recreational drugs. Later in the ICU, she developed severe respiratory distress and worsening hypoxia despite maximum oxygen support and had to be intubated. Her chest X-ray and chest computed tomography (CT) show bilateral diffuse patchy infiltrates compatible with COVID-19 pneumonia, as shown in Figure 1 . She had elevated inflammatory markers, including white blood cells, Creactive protein, lactate dehydrogenase, ferritin, and D-dimer. Her initial laboratory investigations are mentioned in Table 1 . Her COVID-19 was treated with dexamethasone 6 mg twice a day for 10 days and broad-spectrum antibiotics to cover bacterial pathogens. Remdesivir and baricitinib were not given due to transaminitis present at admission. 

The hospital course was complicated by septic shock requiring multiple vasopressors, vaginal bleeding, and shock liver with multi-drug resistant (MDR) Acinetobacter and Pseudomonas pneumonia and persistently elevated D-dimer. She eventually developed acute respiratory distress syndrome (ARDS) and was placed on low positive end-expiratory pressure (PEEP) and high FiO2 as per the ARDS protocol. She failed multiple weaning trials from the ventilator and underwent a tracheostomy and percutaneous endoscopic gastrostomy (PEG) placement.

Later in the hospital course, she developed bilateral upper and lower extremity weakness, predominantly upper extremities. On exam, power in bilateral upper extremities was 0/5, right lower extremity was 3/5, and left lower extremity was 2/5. The sensory sensation was intact in all four extremities. The patient was suspected of having critical illness myopathy. Computed tomography (CT) scan and magnetic resonance imaging (MRI) of the head showed no evidence of acute intracranial hemorrhage, mass effect, midline shift, or recent infarct, as shown in Figure 2 . CT cervical spine showed degenerative spondylosis with moderate to severe central canal stenosis from the C4/5 through C6/7 levels. Neurology was consulted, and electromyography (EMG) was requested. Family members declined lumbar puncture and cerebrospinal fluid (CSF) analysis. Anti-GQ1b ganglioside antibody was negative at <1:100.

The electrodiagnostic study revealed sensorimotor axonal multifocal peripheral neuropathy predominantly affecting upper extremities, as shown in Tables 2-4 . EMG reported reduced amplitude in the right median, ulnar, and peroneal motor compound muscle action potential (CMAP) with normal distal latencies and conduction velocities, absent right radial and medial sensory nerve action potentials (SNAP), normal F-wave latency in the right ulnar, peroneal and tibial. There was likely some degree of cervical radiculopathy on MRI, as shown in Figure 3 . However, the absent sensory responses pointed to a component of neuropathy.

There also appeared to be sural sparing, which can be seen in Guillain-Barré syndrome (GBS), as shown in Tables 2-4 

The patient was discharged to a nursing home for rehabilitation purposes. Three months after the postdischarge patient was successfully liberated from the ventilator and was placed on home oxygen. The patient's neurological signs and symptoms improved significantly over time. The patient did not have any short or long-term treatment complications from intravenous immunoglobulins.

Sars-CoV-2 is one of the types of coronaviruses that causes severe lung infection. While the primary presentation of COVID-19 is respiratory, neurological manifestations and complications are increasing [5] . Guillain-Barre syndrome (GBS) is emerging as a relevant disease that may appear in COVID-19 patients. Sars-CoV-2 mechanism of action is believed to be accessing angiotensin-converting enzyme 2 (ACE2) receptors [2] . ACE2 receptors are present in large numbers in the lung, gastrointestinal tract, cardiomyocytes, urothelial cells, and proximal tubular cells, affecting these systems. The nervous systems, including neurons and glial cells, also express ACE2 receptors, making it a potential target of Sars-CoV-2 [7] .

The first reported case of COVID-induced GBS was from Wuhan, China, which refers to a woman who presented with acute lower extremity weakness and areflexia after four days of returning to Shanghai from Wuhan progressed over three days to the arms without any systemic symptoms. Italy has also reported six patients with GBS [3] . All presented with acute onset of upper and lower extremity weakness, distal paresthesia's, and sensory deficits 3-10 days after experiencing cough, anosmia, ageusia, and sore throat [8] .

GBS is an immune-mediated disorder; molecular mimicry and production of anti-ganglioside antibodies are considered one of the mechanisms of autoimmune disorder that plays an important role [9] . The mechanism of GBS formation in patients infected with COVID-19 has not yet been investigated. Studies on coronaviruses have been shown that neurophilic and neuroinvasive characteristics are present [10] . Although no studies have been directly performed about COVID-19, the arrangement of SARS is very similar to that of COVID-19. One hypothesis shines a light on COVID-19 stimulation of inflammatory cells and the production of various inflammatory cytokines, resulting in the initiation of immune-mediated processes [11] . Our patient had anti-GQ1b ganglioside antibody negative. The rest of the ganglioside panel was not available. Before the COVID-19 pandemic, it was rare to have a negative ganglioside antibody panel for GBS.

There was only one case report with GM1 ganglioside antibody and COVID-19-related GBS [12] . Our case adds to the previously published literature review showing most COVID-19-induced GBS were ganglioside antibody negative pointing towards a different target protein [12] .

GBS presents as progressive ascending weakness of limbs and reduced or loss of deep tendon reflexes. The protein concentration is markedly increased with normal white blood cells on CSF analysis. GBS usually precedes a virus or bacterial infection. The symptoms usually peak within four weeks. Our patient was also noted to develop bilateral upper and lower extremities weakness almost two weeks post-COVID diagnosis. Electromyography (EMG) was also suggestive of GBS. The patient's weakness improved after receiving intravenous immune globulin (IVIG). The axonal variant of GBS takes time to recover due to the nature of the injury but in this case, due to early and prompt IVIG treatment the patient recovered quickly. Months later, the patient was liberated from the ventilator and continued home oxygen. It is crucial to follow longterm sequelae to assess the extent of improvement after receiving intravenous immune globulin. Further investigations and trials should be conducted to better understand the mechanism of GBS in patients of COVID-19. Regarding GBS, clinicians should keep a high suspicion of patients who present with paresthesia and trouble moving after COVID-19 infection [13] .

Physicians should be aware of GBS as a rare complication associated with COVID-19. All patients with neurological deficits with sensory, motor, or autonomic symptoms should be screened for GBS. GBS is an emerging and relevant neurological disease in COVID-19 patients. Its pathophysiology and both clinical and electrophysiological characteristics remain to be further studied. Early diagnosis and management can improve clinical outcomes. Keeping in view the course of the presentation of GBS, therapy with IVIG should be considered along with antiviral treatment to prevent grave complications. It is yet to be confirmed if GBS in COVID patients is caused by an immune response due to molecular mimicry or the production of antiganglioside antibodies. More and more studies are needed to fully understand the nature of COVID-19induced neuropathies and GBS and treatment outcomes. Longitudinal follow-ups are equally essential to comprehend long-term sequelae and outcomes fully.
