Intravenous immunoglobulins versus plasmapheresis in older patients with Guillain-Barre syndrome

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.

Guillain-Barré syndrome in the elderly: clinical, electrophysiological, therapeutic and outcome features

There are few papers devoted to geriatric Guillain-Barré (GBS) and many related issues remain unanswered. OBJECTIVE: To describe clinical, electrophysiological and therapeutic features in this age. METHOD: Clinico-epidemiological data and therapy of GBS patients older than 60 years were reviewed. Hughes scores were used to quantify neurological deficit and define outcome. RESULTS: Among 18 patients (mean age 64.8 years), 9 had evident prodrome and 80% noticed initially sensory-motor deficit. Demyelinating GBS was found in 8 and axonal in 6 subjects. There was one Miller-Fisher and 3 unclassified cases. Plasmapheresis (PFX) was single therapy in 12 patients and intravenous immunoglobulin (IVIg) in 2. Disability scores just before therapy were similar in both groups, so as short and long term outcome. CONCLUSION: Axonal GBS seems to be more frequent in the elderly and this may have prognostic implications. PFX and IVIg were suitable options, but complications were noticed with PFX. Prospective studies are needed to better understand and manage GBS in the elderly.
