...Just as CXCL13 has demonstrated potential clinical utility as a biomarker in infectious diseases involving the CNS, this chemokine has been also proposed as a marker of certain lymphomas....

...Of these, perhaps the best studied are the stages of Lyme disease and syphilis affecting the central nervous system (CNS) (Lyme neuroborreliosis and neurosyphilis)....

...Interestingly, whereas infection with B. burgdorferi appears to have no impact on plasma CXCL13 levels, once the bacteria establishes CNS infection, it leads to constitutively elevated CXCL13 levels in cerebrospinal fluid (CSF), which could be often more than several 100-fold greater than in the plasma (61)....

...CXCL13 appears to recruit B-cells within the CNS and facilitate their differentiation to plasma cells that produce a burgdorferi-targeted humoral response....

...Elevated CXCL13 levels in the CSF have been demonstrated for CNS lymphomas (72), and when elevated together with IL10 in the CSF, CXCL13 has a >99% specificity for primary and secondary lymphomas, leading to similar proposals that it serves as a biomarker for non-Hodgkin lymphoma involving the CNS (73)....

...Our experience has been that repeated CSF cytological orflow-cytometric studies infrequently improves diagnostic yield in PCNSL, supporting development and implementation of other types of molecular diagnostic methods using CSF.38,40,49 Additional standard pretreatment staging tests for PCNSL include complete ophthalmologic examination including slit lamp; contrastenhanced computed tomography (CT) scan of the chest, abdomen, and pelvis; and bone marrow biopsy....

...The activity of intraventricular rituximab was additive or synergistic with methotrexate; this combination appeared to be useful in the setting of a high burden of leptomeningeal disease, eg, lymphoma cell counts.20 000 cells/mL in CSF. Finally, we demonstrated that intraventricular rituximab may overcome resistance mediated by the blood-brain barrier because several responses were noted in the CSF in patients with baseline serum rituximab concentrations.15 mg/mL. Notably, 2 patients achieved a first complete response of CNS lymphoma with intraventricular rituximab/ MTX, including one with CNS lymphoma refractory to high-dose systemic and intrathecal MTX plus 20 previous infusions of intravenous rituximab.108,109 In summary, given the data from a number of prospective trials as well as clinical series that document activity of rituximab in the setting of CNS lymphomas, as monotherapy and in combination with methotrexate-based induction regimens,110 as well as the overwhelming evidence that rituximab improves survival in systemic CD201 NHL, we recommend the incorporation of intravenous rituximab in CD201 CNS lymphoma–directed therapies....

...Measurement of CSF concentration of CXCL13 as well as interleukin (IL)-10 may also be useful in facilitating the diagnosis of CNS lymphoma, both at diagnosis and at relapse.(38) Transcriptional profile studies of PCNSLhave identified a number of potential mediators of disease pathogenesis including upregulated expression of MYC....

...The ability of CSF CXCL13 and IL-10 concentration to identify CNS lymphoma was evaluated by receiver-operating characteristic (ROC) curves.(19,20) Kaplan-Meier and log rank tests were used to assess differences in outcome according to expression of CXCL13 and IL-10....
