Abstract
Objectives: The study aimed to investigate the potential of peripheral myelin protein 2 (P2) and Alpha B-crystallin (αBC) as predictive biomarkers in Guillain-Barré syndrome (GBS). Given the unpredictability of GBS prognosis, the need for specific and reliable biomarkers for disease development and intensity assessment is crucial.
Material and Methods: A prospective observational study was conducted on a cohort of 220 individuals diagnosed with GBS at a tertiary general hospital in South India. P2 and αBC levels in cerebrospinal fluid (CSF) were quantified using ELISA assay kits. The study spanned from March 2021 to April 2023, with participants aged 18–60 years. The study protocol adhered to ethical standards, and the Brighton criteria were employed for GBS diagnosis. CSF samples were collected at admission and two weeks post-onset. Data analysis utilised SPSS, and statistical significance was set at p < 0.05.
Results: Upon admission, mean P2 levels were 2.2 ± 0.5 ng/mL, and αBC levels were 9.8 ± 2.3 ng/mL. After two weeks, P2 increased to 4.8 ± 0.8 ng/mL, and αBC increased to 15.1 ± 2.3 ng/mL. A positive correlation was observed between the rise in P2 and αBC levels and enhanced muscle strength at 4 weeks and 6 months.
Conclusion: The study suggests a significant increase in P2 and αBC levels in GBS patients, correlating with improved muscle strength. P2 and αBC ratios in CSF between the second and first weeks may serve as prognostic markers for GBS. Limitations include a small sample size and the absence of a control group, necessitating caution in generalizability.
