The clinical characteristics and short-term prognosis in elderly patients with Guillain-Barré syndrome

Three-year follow-up outcomes of adult patients with Guillain-Barré Syndrome after rehabilitation

Background

Guillain-Barré syndrome (GBS), the most common cause of acute paralytic neuropathy, covers a number of recognizably different variants. We aimed to evaluate the clinical characteristics of the patients with GBS and the outcome results of the patients after rehabilitation.

Methods

We enrolled 24 adult patients with GBS and evaluated their demographic characteristics, signs, complications, functional levels, and residual symptoms at admission, discharge, and during the 1st and 3rd-year follow-up visits. Functional Independence Scale (FIM), Functional Ambulation Scale (FAS), Hughes functional grading scale, Six-Minute Walking Test (6MWT), and Fatigue Severity Scale (FSS) were used for patient evaluation.

Results

In this study, patients with a mean age of 47.29 ± 16.2 years (40% female) were hospitalized for an average of 28.91 ± 25.6 days. The predominant symptoms experienced by these patients were fatigue (100%), neuropathic pain (70.8%), joint pain (54.2%), and autonomic dysfunction (50%). Significant changes were observed in FIM, Hughes functional grading scale, FAS, 6MWT, and MRC score at admission, discharge, and 1st/3rd-year follow-ups (p=0.000, p=0.000, p=0.000, p=0.001, p=0.000, respectively). Fatigue and Hughes score increased significantly with age (p=0.019, r=0.475; p=0.041, r=0.419, respectively). Negative correlations were found between age and FAS, 6MWT, and MRC score at 1st-year follow-up (p=0.025, r=-0.456; p=0.027, r=-0.450; p=0.008, r=-0.528). FSS was above 4 before admission and in 53.1% at 3rd-year follow-up, correlating negatively with 6MWT and MRC sum score. GBS clinical types showed no significant differences.

Conclusion

Rehabilitation improves functional improvement in GBS patients, with long-term benefits observed. However, residual symptoms such as fatigue and neuropathic pain may persist despite functional improvement. These findings highlight the importance of incorporating rehabilitation into the management of GBS and addressing residual symptoms to improve patient outcomes.

Characteristics of Guillain-Barré syndrome in super-elderly individuals

BACKGROUND

Japan has the world's largest super-aging population, and the number of elderly patients with various diseases is increasing. Herein, we reported the characteristics of super-elderly patients, aged over 80 years, with Guillain-Barré syndrome (GBS), a typical neuroimmune disease.

METHODS

During the period 2019-2021, 74 patients over the age of 80 years diagnosed with GBS at Kindai university were analyzed as the super-elderly group patients. The control group comprised 74 consecutive patients aged < 79 years, under the same conditions. GBS was diagnosed using Brighton diagnostic criteria. Electrophysiology was assessed using the Ho criteria.

RESULTS

The mean age was 83.5 years in the super-elderly group and 51.7 years in the control group. Prior infection was recognized in 50% of cases in the super-elderly group and 77% of cases in the control group with fewer cases in the super-elderly group. The mean number of days until peak symptom presentation was longer in the super-elderly group. The percentage who required a ventilator was significantly higher among the super-elderly group than among the control group. Hughes functional grading scale was more severe in the super-elderly group. Electrophysiological examination revealed the demyelinating form was particularly common in the super-elderly group. Intravenous immunoglobulin was the most common treatment in both the groups, with no difference in efficacy.

CONCLUSIONS

Super-elderly onset GBS tends to be severe, therefore it is important to diagnose and treat appropriately, even in the absence of prior episodes of infection.

Clinical Features and Outcome of the Guillain–Barre Syndrome: A Single-Center 11-Year Experience

Background

Clinical presentation, electrophysiological subtype, and outcome of the Guillain–Barre' Syndrome (GBS) may differ between patients from different geographical regions. This study aims to assess clinical–neurophysiological features of an adult, Italian GBS cohort over 11 years.

Methods

Retrospective (from 1 January 2011 to 31 December 2021) analysis was carried out on patients admitted to the Siena University Hospital who fulfilled the GBS diagnostic criteria. Demographic data, clinical characteristics, treatment, need of mechanical ventilation (MV), laboratory and electrophysiological tests, preceding infections/vaccination/other conditions, and comorbidities were collected for each patient.

Results

A total of 84 patients (51 men, median age of 61 years), were identified. GBS subtype was classified as acute inflammatory demyelinating polyneuropathy (AIDP) in the 66.6% of patients, acute motor/sensory axonal neuropathy (AMAN/AMSAN) in 20.2%, and the Miller Fisher syndrome in 5 (5.9%). Flu syndrome and gastrointestinal infection were the most common preceding conditions. In total, five (5.9%) subjects had concomitant cytomegalovirus (CMV) infection. Cranial nerve involvement occurred in 34.5% of subjects. Differences between the axonal and AIDP forms of GBS concerned the presence of anti-ganglioside antibodies. In total, seven (8.33%) patients required MV.

Discussion

The epidemiological and clinical characteristics of GBS in different countries are constantly evolving, especially in relation to environmental changes. This study provides updated clinical-epidemiological information in an Italian cohort.

Old age and multiple comorbidity are associated with delayed diagnosis of Guillain-Barre syndrome

To assess whether older age and presence of comorbidities were associated with a delayed diagnosis of Guillain-Barré syndrome (GBS). The medical records of 140 patients diagnosed with GBS at Severance Hospital from March 2011 to December 2020 were retrospectively reviewed. Comorbidity profiles were assessed using the Charlson comorbidity index (CCI). The age-adjusted CCI (ACCI) score was calculated, which further incorporated the effect of age. Patients were classified into the early diagnosis group (diagnosis duration ≤ 14 days) and late diagnosis group (diagnosis duration > 14 days). Clinical features and comorbidity profiles were compared between the two groups. The cumulative incidence of diagnosis was compared between the low and high ACCI groups. Age was significantly higher in the late diagnosis group (61.8 ± 15.0 years) than in the early diagnosis group (49.1 ± 18.4, p = 0.001). The CCI score was higher in the late diagnosis group (≥ 3 in 26.1%) than in the early diagnosis group (≥ 3 in 5.1%, p = 0.01). The ACCI score demonstrated a positive correlation with the diagnosis duration (β = 1.636, p < 0.001), indicating that the diagnosis was delayed in patients with a higher ACCI score. The duration from onset to diagnosis was longer in the high ACCI group than in the low ACCI group (log-rank test, p < 0.001). The diagnosis duration was significantly longer, especially in patients with malignancy and cardiovascular diseases. Delayed diagnosis of GBS is associated with older age and multiple comorbidities. Diagnostic delay was significant in patients with malignancies and cardiovascular diseases. Early suspicion of GBS is required in these patients.

Regional Differences of Guillain-Barré Syndrome in China: From South to North

Background

The epidemiological features of Guillain-Barré syndrome (GBS) were different in different areas; a comparison of the disease was needed to identify the variation and prognosis. We compare the epidemiological features of GBS in different areas in China.

Method

A total of 1,191 patients were included. Information was collected in patients diagnosed with GBS and its variants in middle and south China, and then retrospectively reviewed. The patients were divided into four different regions: East China (n = 441), Center China (n = 566), South China (n = 77), and Southwest China (n = 107). These subregions are mainly divided by climate and geographical location. These data were compared with data from a study in East China (Shandong, n = 150) and Northeast China (Changchun, n = 750).

Results

Patients from the south and southwest China were younger than other regions (P = 0.000). A summer peak and an autumn peak were found in northern China, but more patients in winter and spring days in other areas (P = 0.000). Upper respiratory tract infection (URTI) was the preceding event of GBS patients in all regions but rarer in central China (P = 0.001). The proportion of axonal subtype was higher in central and southwest China than in other regions (P = 0.001). Patients in southwest China were more served at nadir and have the longest hospital stay (P = 0.003 and P = 0.000).

Conclusion

The difference between seasonal variation and preceding events was found in different regions in China; clinical features differ among regions in China.

Prognostic Factors in Elderly Patients With Guillain-Barré Syndrome: Does Age Matter?

Introduction

Twenty to 40% of Guillain Barré syndrome (GBS) patients will not be able to walk independently despite effective treatment. Older patients carry additional risks for worse outcomes.

Methods

A single center, ambispective cohort study was performed. Only subjects ≥18 years with a 3-month follow-up were included. Elderly patients were considered as a whole if ≥ 60 years. Demographics, CSF and nerve conduction studies were compared. A binomial logistic regression and Kaplan-Meier analyses were carried out to estimate good prognosis (Hugues ≤2) at 3-month follow-up.

Results

From 130 patients recruited, 27.6% were elderly adults. They had a more severe disease, higher mEGOS and more cranial nerve involvement. Age ≥70 years, invasive mechanical ventilation and axonal subtype, portrayed an unfavorable 3-month outcome. Further analysis demonstrated an earlier recovery in independent walk at 3 months for patients <70 years.

Conclusions

Elderly patients with GBS have a more severe disease at admission and encounter worse prognosis at 3-month follow-up, especially those above 70 years.

Guillain-Barre syndrome during COVID-19 pandemic: an overview of the reports

Similar to severe acute respiratory syndrome coronavirus (SARS-CoV) and Middle East respiratory syndrome coronavirus (MERS-CoV), the coronavirus disease 2019 (COVID-19) has neurological symptoms. COVID-19 patients have such clinical symptoms as headache, vomiting, nausea, dizziness, myalgia, anosmia, ageusia, and disorder of consciousness. These symptoms confirm that the nervous system is involved in the COVID-19 infection. Guillain-Barré syndrome (GBS) is a heterogeneous disorder which often follows a viral infection. According to the assessment case reports from the beginning of the COVID-19 infection so far, it is possible that GBS is linked to the COVID-19 infection. It seems that paying attention to the neurological effects of COVID-19 is necessary.

Electrophysiological Subtypes and Prognostic Factors of Guillain-Barre Syndrome in Northern China

Objectives: To assess the epidemiology of different electrophysiological subtypes of Guillain-Barre syndrome (GBS) and investigate the factors affecting the prognosis of the acute motor axonal neuropathy (AMAN) subtype in northern China.

Methods: According to the National Institute of Neurological Disorders and Stroke diagnostic criteria for GBS, 104 consecutive GBS patients were recruited from the Department of Neurology of the Second Hospital of Hebei Medical University, China from 2014 to 2018.

Results: Based on nerve conduction studies (NCSs), AMAN was the most common subtype in Northern China, accounting for 58 patients (55.8%). AMAN patients had significantly higher prevalence of antecedent diarrhea, longer duration of hospitalization, and slightly slower recovery than those with acute inflammatory demyelinating polyneuropathy (AIDP), but there was no statistical difference in disease severity or short-term prognosis between AMAN and AIDP. Based on multivariate regression analysis, AMAN patients with antecedent diarrhea (OR = 0.16, 95% CI: 0.03–0.756, p = 0.021) or conduction blocks (CBs) (OR = 0.033, 95% CI: 0.001–0.787, p = 0.035) had dramatically better short-term prognosis. Decreased compound action potential with distal stimulation (dCMAP) amplitude was associated with significant slower speed of recovery(OR = 8.31, 95% CI: 2.55–27.10, p = 0.02).

Conclusion: AMAN is still the most common subtype of GBS in northern China. A decline in dCMAP amplitude is predictive factor of a slow recovery and poor outcome of GBS. Diarrhea and CBs may be the factors for better short-term prognosis in AMAN patients in Northern China.

Clinical Profile, Functional Outcome, and Mortality of Guillain-Barre Syndrome: A Five-Year Tertiary Care Experience from Nepal

Introduction

Guillain-Barre syndrome is the most common cause of acute flaccid paralysis in the adult population. It occurs at the rate of 0.34 to 4 per 100000 individuals. This study was conducted to determine the clinicoepidemiological profile and outcome of the patients with Guillain-Barre syndrome.

Materials and Methods

We conducted a retrospective study of patients with Guillain-Barre syndrome, presented at B.P. Koirala Institute of Health Sciences, a tertiary care centre in eastern Nepal, from January 2013 to December 2017. All patients diagnosed with Guillain-Barre syndrome were included in this study. The handwritten case record files of the study population were retrieved from medical record section of the institute.

Results

Of 31 patients with Guillain-Barre syndrome, the mean age of patients was 17±12 years. The most common presenting symptom of study population was ascending paralysis (93.5%). Respiratory failure requiring mechanical ventilation occurred in 16.1%. The common variants are AIDP and AMAN. Respiratory tract infection (29%) was the most common antecedent event. The in-hospital mortality of Guillain-Barre syndrome was 6.45%.

Conclusion

Guillain-Barre syndrome is commonly seen in the young population. The most common symptom of Guillain-Barre syndrome was ascending paralysis. The in-hospital mortality rate of patients with GBS was 6.45%.
