Disability and quality of life in Guillain-Barré syndrome - Longitudinal study

Longitudinal health-related quality of life (QoL) data in Guillain-Barré (GBS) patients are still scarce. We, therefore, investigated health- related QoL in GBS patients from Serbia and surrounding countries during a six-month follow-up period, and analyzed its association with patients' disability. Our study comprised 74 adult patients diagnosed with GBS from May 2017 until May 2018 in seven tertiary healthcare centers. Health-related QoL was investigated using the SF-36 questionnaire, and compared with functional disability assessed by the GBS disability scale (GDS). Tests were performed at day 14, day 28, month 3 and month 6 from disease onset. GDS and SF-36 scores improved over time (p < 0.01). GDS scores were different at all four time points, while SF-36 did not differ between day 14 and day 28. Pooled SF-36 scores (especially physical ones) correlated with pooled GDS scores, except for Bodily Pain and Role Emotional scores. We found that GDS score at day 14 was an independent predictor of GDS score at month 6 (β = +0.52, p < 0.01), while SF-36 score at day 14 was an independent predictor of SF-36 score at month 6 (β = +0.51, p < 0.01). Neurologists should look not only on disability but also on QoL in GBS patients, since these two measures provide us with important complementary items of information.
