Background:
The independent prognostic value of cerebrospinal fluid analysis in multiple sclerosis is not established.
Objective:
To determine the prognostic value of intrathecal synthesis in a cohort of patients with relapsing-onset MS taking into consideration demographic and imaging parameters.
Methods:
In this prospective cohort study conducted from 1993 to 2013, we analyzed the time to confirmed disability (persistent above 6 months) and irreversible disability (persistent for the entire disease course) of two disability milestones, Expanded Disability Status Scale score ≥ 4 or 6, and the time to secondary progressive onset in 579 patients with relapsing-onset multiple sclerosis. Demographic parameters (age at onset, gender) and imaging parameters (periventricular lesions) were included in the Cox models.
Results:
447 patients (77.2%) had intrathecal synthesis (oligoclonal bands and/or increased immunoglobulin G index value). No statistically significant relation was found between intrathecal synthesis and the time to reach each disability milestone or secondary progressive onset. An age older than 40 years and more than 3 periventricular lesions predicted a worse prognosis.
Conclusions:
Cerebrospinal fluid analysis did not predict the time to disability milestones in relapsing-onset multiple sclerosis independently of age and imaging data.
