Abstract

ABSTRACT: Objective: This study aimed to explore the correlation of elevated glucose levels in the blood and cerebrospinal fluid with the progression and short-term prognosis of Guillain-Barré syndrome (GBS). Methods: The medical records of 982 patients who were diagnosed with GBS in 31 representative tertiary hospitals, located in 14 provinces in southern China, were collected and retrospectively reviewed. Patients were grouped according to the levels of fasting plasma glucose (FPG) and cerebrospinal fluid (CSF) glucose, as well as the concentration of blood hemoglobinAlc (HbA1c). The Hughes grade scale was used to quantify functional outcomes. Results: Compared to patients with normal FPG and CSF glucose levels, those in the high FPG and high CSF glucose groups were characterized by a higher proportion of severe patients (HFGS ≥ 3) at admission (58.8 vs . 73.1, P = 0.000; 57.6 vs . 71.2, P = 0.000), at nadir (67.4 vs . 83.0, P = 0.000; 66.2 vs . 80.4, P = 0.000), and at discharge (29.8 vs . 46.3, P = 0.000; 26.4 vs . 45.0, P = 0.000). Patients in the high HbA1c group also had more severe disability at admission (74.6 vs . 56.1, P = 0.005) and at nadir (80.3 vs . 64.3, P = 0.012) compared to the normal HbA1c group. Moreover, elevated levels of FPG and CSF glucose were significantly correlated with more severe disability at admission, at nadir, and at discharge. Conclusions: The present study showed that elevated glucose levels in the blood and cerebrospinal fluid were associated with the severity and short-term prognosis of GBS.
