Clinical Characteristics and Prognostic Factors of Children with Guillain-Barré Syndrome

Comparison of Clinical Features, Short-Term Outcome of Guillain-Barré Syndrome Between Adults and Children: A Retrospective Study in Vietnam

BACKGROUND

Despite extensive research on Guillain-Barré syndrome (GBS) in adults and children, there is a lack of comparison regarding short-term outcomes in various age groups. Our study aims to elucidate the differences in clinical features and short-term outcomes in Vietnam.

METHODS

After retrospective data collection, we compared clinical features in patients with GBS aged ≤16 years at Children's Hospital 2 and aged >16 years at University Medical Center Ho Chi Minh City from 2017 to 2021. A positive short-term outcome was recorded if patients had a GBS Disability Score of 0 to 2 at hospital discharge.

RESULTS

We analyzed 109 adults (58.7% males; mean age 50.6 ± 17.7) and 111 children (58.6% males; mean age 7.2 ± 4.9). Comparable antecedent infection and immunization incidence in both groups were observed (35.8% vs 45.9%, P > 0.05). Pain and sensory disturbance were the most common onset symptom in adults (57.8%), whereas lower limb weakness predominated in children (61.3%). Ophthalmoplegia (18.3% vs 5.4%), pain, sensory disturbance (85.3% vs 67.6%), ataxia (33.0% vs 15.3%) were more prevalent in adults (P < 0.05). The axonal subtype was prominent in both adults (51.4%) and children (53.2%). Patients were classified into: classic GBS (49.5% and 68.5%), GBS variants (11.0% and 15.3%), classic Miller Fisher syndrome (MFS) (1.8% and 1.8%), MFS variants (2.8% and 0%), and GBS/MFS overlap (34.9% and 14.4%). Short-term outcomes did not significantly differ based on age.

CONCLUSIONS

Age-related variations in clinical features were observed, but adults and children exhibited similar short-term functional outcomes.

The characteristics of Guillain-Barre syndrome in children in pre-COVID-19 and during the COVID-19 pandemic: A cross-sectional study

Background and Aims

In the pathophysiology of Guillain-Barre syndrome (GBS), inflammation and immunity are believed to play a key role. The neutrophil-lymphocyte ratio (NLR), monocyte-lymphocyte ratio (MLR), and platelet-lymphocyte ratio (PLR) have been recently identified as potential markers of inflammation or immunity. This study aimed to investigate whether NLR, MLR, and PLR are associated with GBS characteristics in children. We also assessed the impact of the COVID-19 pandemic on the characteristics of GBS in Iran.

Methods

In this retrospective cross-sectional study, we reviewed the records of all 150 children diagnosed with GBS in the Children's Medical Center hospital affiliated with Tehran University of Medical Sciences (TUMS) from March 2017 until March 2022. The TUMS research ethics committee approved the study (Ethics code: IR.TUMS.CHMC.REC.1399.125). Patients' data including gender, age, clinical symptoms, laboratory findings, and electrodiagnostic study results were collected and analyzed.

Results

This study involved 150 children, comprising 93 boys and 57 girls, with an average age of 7.53 ± 3.75 years. The analysis demonstrated that the number of hospitalization days increased with an increase in NLR (p = 0.025). Moreover, patients with abnormal electrodiagnostic study patterns had a higher risk of intensive care unit (ICU) admission (p: 0.027), although according to binary logistic regression, respiratory failure at admission time was the only significant factor increasing the risk of ICU admission (p = 0.035). The study also found that the pandemic has resulted in a shift from acute inflammatory demyelinating polyneuropathy to acute motor axonal neuropathy as the most common EMG-NCV pattern in our patients (p < 0.001).

Conclusion

We found that higher NLR was associated with a longer hospitalization duration and could potentially distinguish between severe and mild cases of GBS. We have also shown that the COVID-19 pandemic has changed our patients' most frequent electromyography and nerve conduction velocity (EMG-NCV) patterns.

Pediatric Guillain-Barré Syndrome in a Resource Limited Setting: Clinical Features, Diagnostic and Management Challenges, and Hospital Outcome

Background

Guillain-Barré syndrome (GBS) is an acute immune-mediated peripheral neuropathy with a highly variable clinical course and outcome. There remain diagnostic and treatment challenges in resource limited settings. This study aimed to describe the clinical presentation, diagnostic and management challenges, and hospital outcome of children with GBS in southern Ethiopia.

Methods

A retrospective chart review of children aged ≤14 years who were admitted with a diagnosis of GBS to Hawassa University Comprehensive Specialized Hospital from 2017 to 2021 was done. Medical records of 102 children who fulfilled the Brighton Criteria for GBS were reviewed, and data on demographic, clinical characteristics, investigation findings, treatment, and outcome were collected. Logistic regression analysis was done to determine factors associated with mortality.

Results

The mean age of the study subjects was 7.25±3.91 years and 63.7% were male. Antecedent event was present in 48% of the cases, and the most common triggering factor was upper respiratory tract infection (63.8%). The mean Hughes disability score was 4.23±0.54, 4.48±0.71, and 4.03±0.86 at admission, nadir and discharge from hospital, respectively. Cranial nerve involvement was present in 27.5% of patients and bulbar palsy was the most common finding. Dysautonomia was observed in 57.8% of the participants. Sixty-three patients (61.8%) needed ICU care but only 43 of them (68.3%) were admitted to ICU. Similarly, 31 patients (30.4%) required respiratory support but only 24 of them (77.4%) were on mechanical ventilator. No patient had nerve conduction study. Only 5.9% of patients received IVIG. Thirteen patients (12.7%) died of GBS and the presence of respiratory failure was the only determinant of mortality [AOR = 11.40 (95% CI: 1.818, 71.52), p = 0.009].

Conclusion

There is a gap in the diagnosis and management of children with GBS; and mortality from the disease is higher than reports from other settings.

Role of the Neutrophil to Lymphocyte Ratio in Guillain Barré Syndrome: A Systematic Review and Meta-Analysis

In this study, we conducted a systematic review and meta-analysis regarding the role of the neutrophil to lymphocyte ratio (NLR) in Guillain Barré syndrome (GBS). The most recent update to the search was on July 18, 2022, through the databases of Web of Science, PubMed, Embase, and Scopus. The Newcastle-Ottawa scale was used for quality assessment of included studies. Finally, 14 studies were included in the review, and among them, ten studies were included in the meta-analysis. Our results showed that NLR levels were significantly increased in the patients with GBS compared with healthy controls (SMD = 1.05; 95%CI = 0.59 to 1.50, P < 0.001). After treatment, NLR levels were decreased to the extent that they became similar to healthy controls (SMD = -0.03, 95%CI = -0.29 to 0.22, P = 0.204). Moreover, NLR was a stable predictor of outcome or response to treatment in such patients (SMD = 1.01, 95%CI = 0.65 to 1.37, P < 0.001); the higher the NLR, the worse the outcome. In addition, patients who underwent mechanical ventilation had higher levels of NLR compared to those who did not (SMD = 0.93, 95%CI = 0.05 to 1.82, P = 0.03). However, NLR levels were not different among distinct GBS subtypes, so it could not distinguish among them. In conclusion, our analysis indicates that the NLR levels are highly elevated in patients with GBS. Therefore, the NLR has the potential to be used as a biomarker to inform diagnosis, prognosis, or treatment responses in GBS, and future studies are warranted.

A novel prognostic system based on clinical and laboratory parameters for childhood Guillain-Barre syndrome

AIM

To develop a score based on clinical and laboratory parameters in acute-phase of GBS to predict outcome at 6 months.

METHODS

Clinical and laboratory assessment at admission including blood neutrophil-to-lymphocyte ratio (NLR), pre and post-immunotherapy serum albumin was prospectively performed in pediatric-GBS cases at a tertiary-care hospital over 1 year. Clinical features and laboratory test results were compared between children with complete (Hughes Disability Score; HDS ≤ 1) and incomplete recovery (HDS > 1) at 6 months from onset, using univariate and multivariate analysis. Area-under-receiver-operating-characteristic-curve (AUC) of predictors of prognosis and their optimal cutoffs were assessed.

RESULTS

Forty-six patients were enrolled (mean age 69.1 ± 35.2 months; male 57.6%). Factors on admission that independently predicted poor-outcome at 6 months were older age, feeble voice, lower NLR and lower post-immunotherapy serum albumin. AUCs and optimal cutoffs of NLR and post-immunotherapy serum albumin for predicting disability at 6 months were 0.729, 0.781 and ≤ 1.65, ≤ 34.5 g/L, respectively. AUCs of clinical parameters such as older age and feeble voice were 0.749 and 0.713 respectively. King GBS outcomescore including all predictors had maximum AUC of 0.971 (95% CI 0.921-1.02). The score at cutoff ≥ 3 demonstrated excellent sensitivity (92.3%) and specificity (96.7%) to determine poor outcome.

CONCLUSIONS

This new prognostic system may be beneficial in recognising children-at-risk of poor prognosis who may benefit from additional treatment.
