Guillain-Barré Syndrome After Cardiopulmonary Bypass

Guillain-Barre syndrome after coronary artery bypass graft surgery: a case report and literature review

Background

Guillain-Barre syndrome (GBS) is an acute polyradiculoneuropathy, often preceded by an infection. Rarely, it is preceded by a surgical procedure. Most of the postsurgical GBS cases are reported with the neurosurgical, gastrointestinal, orthopedic, and cardiac procedures. GBS is rarely reported after a coronary artery bypass grafting (CABG). To date, only 12 cases have been reported in the literature. Our case is 13th in number and the first case from Pakistan.

Case presentation

We report a case of a 54-year-old man presented with acute flaccid quadriparesis and areflexia after a CABG procedure. He was subsequently diagnosed with an acute inflammatory demyelinating polyneuropathy (AIDP) variant of GBS and underwent five sessions of plasmapheresis. His weakness improved and could ambulate unassisted on follow-up visits.

Conclusion

GBS is a potentially treatable condition if timely diagnosed and managed. It should be considered in every patient presenting with an acute-onset weakness after surgery.

Guillain-Barré syndrome after aortic, tricuspid, and mitral valve surgery

Guillain-Barré syndrome incidence within 8 weeks of a surgical procedure appears to be more common than previously thought. GBS following open-heart surgery is exceedingly rare, perhaps underdiagnosed or underreported given surveillance data incidence. Clinicians should be keenly aware of this association and quickly consider a GBS diagnosis.

Trauma-Related Guillain-Barré Syndrome: Systematic Review of an Emerging Concept

Guillain-Barré syndrome (GBS) is mainly associated with preceding exposure to an infectious agent, although the precise pathogenic mechanisms and causes remain unknown. Increasing evidence indicates an association between trauma-related factors and GBS. Here, we performed a systematic review, summarized the current scientific literature related to the onset of GBS associated with trauma, and explored the possible pathogenesis. A literature search of various electronic databases was performed up to May 2020 to identify studies reporting diverse trauma-related triggers of GBS. Data were extracted, summarized descriptively, and evaluated with respect to possible mechanisms. In total, 100 publications, including 136 cases and 6 case series involving GBS triggered by injury, surgery, intracranial hemorrhage, and heatstroke, met our eligibility criteria. The median age of the patients was 53 [interquartile range (IQR) 45-63] years, and 72.1% of the patients were male. The median number of days between the trigger to onset of GBS symptoms was 9 (IQR 6.5-13). Overall, 121 patients (89.0%) developed post-injury/surgical GBS, whereas 13 (9.6%) and 2 (1.5%) patients had preexisting spontaneous intracranial hemorrhage and heatstroke, respectively. The main locations of injury or surgeries preceding GBS were the spine and brain. Based on available evidence, we highlight possible mechanisms of GBS induced by these triggers. Moreover, we propose the concept of "trauma-related GBS" as a new research direction, which may help uncover more pathogenic mechanisms than previously considered for typical GBS triggered by infection or vaccination.

Surgery and risk of Guillain-Barré syndrome: A French nationwide epidemiologic study

OBJECTIVE

To assess the association between Guillain-Barré syndrome (GBS) and recent surgery based on French nationwide data.

METHODS

Data were extracted from the French health administrative databases (SNIIRAM/PMSI). All patients hospitalized for GBS between 2009 and 2014 were identified by ICD-10 code G61.0 as main diagnosis. Patients previously hospitalized for GBS in 2006, 2007, and 2008 were excluded. Surgical procedures were identified from the hospital database. Hospitalizations for surgery with no infection diagnosis code entered during the hospital stay were also identified. The association between GBS and a recent surgical procedure was estimated using a case-crossover design. Case and referent windows were defined as 1-60 days and 366-425 days before GBS hospitalization, respectively. Analyses were adjusted for previous episodes of gastroenteritis and respiratory tract infection, identified by drug dispensing data.

RESULTS

Of the 8,364 GBS cases included, 175 and 257 patients had undergone a surgical procedure in the referent and case windows, respectively (adjusted odds ratio [OR] = 1.53, 95% confidence interval [CI]: 1.25-1.88). A slightly weaker association was observed for surgical procedures with no identified infection during the hospitalization (OR = 1.40, 95% CI: 1.12-1.73). Regarding the type of surgery, only surgical procedures on bones and digestive organs were significantly associated with GBS (OR and 95% CI = 2.78 [1.68-4.60] and 2.36 [1.32-4.21], respectively).

CONCLUSION

In this large nationwide epidemiologic study, GBS was moderately associated with any type of recent surgery and was more strongly associated with bone and digestive organ surgery.

Increased incidence of Guillain-Barré syndrome after surgery

BACKGROUND AND PURPOSE

Antecedent surgery has been described to trigger Guillain-Barré syndrome (GBS), but its evidence is poor and based on case reports only.

METHODS

We performed a retrospective analysis of 63 patients with GBS admitted to the University Hospital Basel and University Children's Hospital Basel from January 2005 to December 2010. We calculated and compared the incidences of post-surgical and non-exposed patients with GBS in the study population and those reported previously in literature.

RESULTS

Six of 63 (9.5%) GBS cases had had a surgery within 6 weeks prior to GBS. The relative risk of developing GBS during the 6-week period after surgery is 13.1 times higher than the normal incidence in the study population (95% confidence interval: 5.68, 30.3; P ≤ 0.0001), suggesting an attributable risk of 4.1 cases per 100, 000 surgeries. In addition, the incidence of post-surgical GBS is significantly higher than influenza vaccine-associated GBS in the study population (P = 0.01) as well as in comparison with previous reported vaccine-associated GBS (P ≤ 0.0001) and background incidences (P ≤ 0.0001).

CONCLUSION

Surgery must be considered to be a potential risk factor for developing GBS.
