Overview

The coronavirus (COVID-19) pandemic originated in Wuhan (China) on December 2019.Although respiratory complications are more common, neurological manifestations are also increasingly reported. Guillain-Barre syndrome is preceded by upper respiratory infection or gastrointestinal illness. In June 2020,the very first case of COVID-19 associated Guillain-barre syndrome in the United States was reported. The polyneuropathy in Guillain–Barre syndrome is believed to be due to cross-immunity against epitopes of peripheral nerve components that it shares with the epitopes on the cell surface of bacteria that produces an antecedent infection. If left untreated, COVID-19 associated GBS may cause respiratory failure. The classic clinical manifestations of Guillain-Barre syndrome is progressive, ascending, symmetrical flaccid limbs paralysis.

Historical Perspective

  • In northern Italy five patients developed Guillain–Barré syndrome after the onset of coronavirus disease 2019 (Covid-19) from February 28 through March 21, 2020.[2]
  • In June 2020,the very first case of COVID-19 associated Guillain-barre syndrome in the United States was reported.[3]

Classification

  • There is no established system for the classification of COVID-19 associated Guillain-Barre Syndrome .
  • Guillain-Barre Syndrome its self may be classified into various subtypes: Demyelinating polyneuropathy (67.4%), acute axonal neuropathy (7.0%), Miller Fisher syndrome (7.0%), Bickerstaff brainstem encephalitis (7.0%), pharyngo-cervical-brachial variant (4.7%), and polyneuritis cranialis (4.7%).[4]

Epidemiology and Demographic

  • Five cases of Guillain-Barre syndrome (GBS) in patients with COVID-19 has been reported in three hospitals in Northern Italy from February 28 through March 21, 2020.Four of these patients had a positive nasopharyngeal swab for SARS-CoV-2 at the onset of the neurologic syndrome, and one had a negative nasopharyngeal swab and negative bronchoalveolar lavage but subsequently he developed a positive serologic test for the virus [2].
  • The first official case of Guillain-Barre syndrome (GBS) associated in patients with COVID-19 in the United States has been reported by neurologists from Allegheny General Hospital in Pittsburgh, Pennsylvania in June,2020.The patient was a 54-year-old man who was transferred to Allegheny General Hospital after developing ascending limb weakness and numbness that followed symptoms of a respiratory infection.The man reported that his wife was tested positive for COVID-19 infection and that his symptoms started soon after her illness.Later he also tested positive for COVID-19.[24]
  • Another case of Guillain–Barre syndrome with COVID-19 has been reported in Iran[25].
  • One case of Guillain–Barre syndrome with COVID-19 was reported in the UK.The patient was a 49-year-old man of South Asian descent with no medical history and reported a 3-week history of shortness of breath, headache and cough.He came to emergency department with worsening cough and distal lower limb paraesthesia during the previous week, resulting in difficulty mobilising.[26]
  • There was also one case of SARS-CoV-2 infection associated Guillain-Barre syndrome in a child.The patient was an eleven year old boy who presented with typical features of GBS.The diagnosis of the SARS-CoV-2 infection was confirmed by oropharyngeal swab on reverse transcription polymerase chain reaction assay.[27]
  • Familial occurrence of Guillain-Barré syndrome after COVID-19 infection has also been reported.2 members of a family affected by COVID-19 presented with ascending paresthesia with the final diagnosis of Guillain-Barre syndrome.The patient was a 38-year-old man who presented with a history of ascending paresthesia and bilateral facial droop for 5 days before admission and was treated with a diagnosis of Guillain-Barre syndrome, his 14-year-old daughter also presented with a history of progressive paresthesia and weakness. Similar to her father, the paraclinical evaluations were consistent with Guillain-Barre syndrome.[28]

Risk Factors

Screening

Natural History, Complications, and Prognosis

  • If left untreated, COVID-19 associated GBS may cause respiratory failure.
  • Among the five Italian patients of Covid-19 associated GBS two patients had poor outcome including ICU admission due to respiratory failure,they remained in intensive care after 4 weeks of treatment ;two patients had mild improvement and receiving physical therapy, and one was discharged walking independently.[29][2]
  • The only US patient with COVID-19 associated GBS briefly required mechanical ventilation and was successfully weaned after receiving a course of Intravenous Immunoglobulin.[3]

Primary Prevention

  • The disease itself is associated with COVID-19 infection and it is believed that preventing the spread of the infection itself is the most promising primary prevention strategy at the moment.
  • There have been rigorous efforts in order to develop a vaccine for novel coronavirus and several vaccines are in the later phases of trials.[35]
  • According to the CDC, the measures to prevent the spread the COVID-19 infection include:[36]
    • Frequent handwashing with soap and water for at least 20 seconds or using a alcohol based hand sanitizer with at least 60% alcohol.
    • Staying at least 6 feet (about 2 arms’ length) from other people who do not live with you.
    • Covering your mouth and nose with a cloth face cover when around others and covering sneezes and coughs.
    • Cleaning and disinfecting.

Secondary Prevention
