Similarly, in a slightly larger cohort (n = 26), Pilz et al. also showed a higher CSF-CXCL13 value, as well as CSF/serum albumin ratio, in the first and second lumbar puncture in complicated courses (n = 8; encephalitis +/− vasculitis, myelitis) in contrast to meningitis/monoradiculitis (uncomplicated course; n = 18) [41]. The gene discussed is CXCL13; the disease is vasculitis.
