Contribution of cerebrospinal fluid sCD19 levels to the detection of CNS lymphoma and its impact on disease outcome.

چکیده
Flow cytometry (FCM) is more sensitive than conventional cytology for detection of occult leptomeningeal lymphoma; however, some FCM-negative patients show central nervous system (CNS) recurrence. Here, we evaluated the cerebrospinal fluid (CSF) levels of 13 B-cell-associated markers and their contribution to the diagnosis of CNS lymphoma in 91 diffuse large B-cell lymphomas (DLBCL) and 22 Burkitt lymphomas (BLs). From all markers tested, CD19 was the most informative. Thus, higher soluble CD19 (sCD19) levels were associated with a greater frequency of neurological symptoms in DLBCL and BL and with parenchymal CNS lymphoma in DLBCL; sCD19 emerged as a powerful predictor of event-free and overall survival in DLBCL and BL, particularly when combined with FCM detection of CNS disease. These results support the utility of combined FCM detection of lymphoma cells and assessment of sCD19 levels in CSF, for more accurate identification of CNS disease in DLBCL and BL patients.

Detection of Herpes Simplex Virus Infection in Cerebrospinal Fluid
ABSTRACT Background and Objective: Herpes simplex encephalitis is a life-threatening consequence of the central nervous system (CNS) infection with Herpes simplex virus (HSV). Although it is a rare disease, mortality rates reach 70% in the absence of therapy and only a minority of individuals can return to normal function. The aim of this study was to d...
متن کاملCerebrospinal fluid polyamines in childhood leukemia.
Cerebrospinal fluid (CSF) polyamines were measured in children with acute lymphocytic leukemia or non-Hodgkin's lymphoma in various stages of the disease ranging from complete remission to active central nervous system (CNS) involvement. Polyamines were analyzed by ion exchange chromatography with o- pthalaldehyde fluorimetric detection. Putrescine concentrations in random CSF samples obtained ...

Background: Behçet's disease (BD) is a systemic inflammatory disease with a chronic, relapsing-remitting course of unknown etiology. Neuro-Behcet’s disease (NBD) induce serious CNS complications and are known to be the main cause of long-term morbidity and mortality. IL‐37 is a natural suppressor of innate inflammation which its role in NBD has not been fully understood. <stron...
متن کاملDevelopment of an RP-HPLC-UV method for simultaneous detection of nimodipine and its metabolite in cerebrospinal fluid of rat
A rapid, simple and reproducible HPLC method was developed and validated for the analysis of nimodipine (NM) and/or its metabolite, oxidized nimodipine (OX–NM) in rat cerebrospinal fluid (CSF) and artificial CSF. The NM and OX–NM were eluted in less than 10 min with no interferences from the endogenous CSF peaks. Analysis was carried out on a Eurospher Performance (RP-C18, 250 × 4.6 mm) column ...
