The prognostic value of oligoclonal bands in the cerebrospinal fluid of Multiple Sclerosis (MS) patients is controversial. While several studies have demonstrated a worse disease course in OCB positive patients, others did not reproduce these findings. We evaluated the prognostic significance of OCB retrospectively based on clinical records of OCB status upon diagnosis and severity outcomes including the MS Severity Score, Progression Index and regional involvement in Magnetic Resonance Imaging. OCB positive patients had a higher median MSSS and PI, and a greater proportion of spinal cord involvement. These findings provide further evidence of the prognostic importance of OCB in MS patients.
