Table 16 Overview of relevant CSF parameters and frequency of abnormalities during relapse and in remission

From: S1 guidelines “lumbar puncture and cerebrospinal fluid analysis” (abridged and translated version)

ParameterRelapseRemissionRemarks
NMOSD with AQP4-IgGa
 Cell count> 4/μL: ca. 60 - 78%
> 100/μL: ca. 6%
Mostly normal (> 5/μL: 20%; > 100/μL: 0%)Negative correlation between cell count and time (in days) since onset of relapse
 Cell profile- lymphocytes and monocytes (97% of cells)
- neutrophils in 40-60% (rarely dominant cell population)
- eosinophils in 10-15%
- basophils in 2-4%
- activated lymphocytes or
- plasma cells in up to 20% (up to approximately 15% of all cells)

- plus neutrophils in 64% of cases with pleocytosis
 Pleocytosis more frequent in patients with myelitis as first manifestation

  1. aIn NMOSD with AQP4-IgG cell count, QAlb, QIgG, total protein, and lactate are more frequently increased and the increase is more pronounced in acute myelitis than in acute optic neuritis
