Correlation of Total Protein in Cerebrospinal Fluid with the Type of Guillain-Barre Syndrome based on the Electrodiagnostic Examination at Prof. Dr. IGNG Ngoerah General Hospital Denpasar

Introduction: Guillain-Barre syndrome (GBS) is an autoimmune disease of the peripheral nervous system with an incidence of around 0.6 to 2.4 cases per 100,000 population. GBS pathogenesis is related to inflammatory factors, cytokines, chemokines, and complement. Protein levels in the cerebrospinal fluid of GBS patients will increase due to damage or increased permeability of the blood-nerve barrier and blood-cerebrospinal fluid (CSF) barrier. However, there are still pros and cons to the relationship between the amount of CSF protein and the subtype of GBS. Objective: To determine the most common GBS subtype and the characteristics of electrodiagnostic examination at Prof Dr IGNG Ngoerah General Hospital and the relationship between the GBS subtype characteristics on electrodiagnostic examination and CSF protein levels. Methods: This study used an analytic observational study with a cross-sectional study design with consecutive sampling. The sample of this study is 42 GBS patients (21 patients with normal total protein and 21 patients with increased total protein) at Prof Dr IGNG Ngoerah General Hospital, Denpasar-Bali. Data is collected through medical records and analyzed by Chi-Square test. Results: There is no correlation between the increase in total CSF protein in GBS patients and the GBS subtype on electrodiagnostic examination (p=0.215). Discussion: The most common GBS subtype is the AIDP type. Although the average amount of CSF protein was higher in the AIDP, AMAN and AMSAN subtypes respectively, the increase in total CSF protein did not have a significant relationship to the GBS subtype in Prof Dr IGNG Ngoerah General Hospital, Denpasar-Bali.
