natriuretic-peptide--brain and Meningioma

This study aimed to investigate the association of high-sensitivity C-reactive protein (hsCRP) and. 177 brain tumor patients awaiting for brain tumor surgery participated in the study. Patients were assessed preoperatively, using neuropsychological tests for verbal memory, psychomotor speed, mental flexibility, and verbal fluency. The functional status of patients was evaluated using the Karnofsky Performance Index. Blood samples were drawn for evaluation of serum hsCRP and NT-proBNP concentrations upon hospital admission.. The highest NT-proBNP concentration was observed in meningioma patients. Glioma and meningioma patients did not differ in hsCRB concentration. Patients in the highest hsCRP tertile were older and more frequently reported cardiovascular comorbidity. Patients in the highest NT-proBNP tertile were older, more frequently with cardiovascular comorbidity, females, and diagnosed with a meningioma. hsCRP was significantly related to slower psychomotor speed in high-grade glioma patients (. NT-proBNP was not associated with memory, language, and attention/executive cognitive domains of glioma and meningioma patients. Increased hsCRP was related to slower psychomotor speed and worse mental flexibility in glioma patients, indicating that inflammation processes are important for cognitive functioning in glial tumors.

A positive correlation between serum B-type natriuretic peptide levels and the amount of dislodgement of intracranial structures (mass effect) produced by brain tumors has been demonstrated previously. The aim of our prospective observational study was to evaluate a possible relationship between serum B-type natriuretic peptide levels and the amount of neoplastic edema in patients affected by brain tumor.. We prospectively studied 110 patients with a supratentorial brain tumor. Serum N-terminal-pro B-type natriuretic peptide was measured and brain magnetic resonance images were analyzed to discriminate between neoplastic tissue and perilesional edema. A multivariate linear regression model predictive for serum N-terminal-pro B-type natriuretic peptide levels was generated.. The radiologic diagnoses were meningioma in 45 patients (40.9%), glioma in 33 (30%), and metastasis in 32 (29.1%). A mass effect was present in 29 (26.4%) patients. Serum N-terminal-pro B-type natriuretic peptide was 125.61 ± 174.14 pg/mL (median 60 pg/mL, interquartile range 28-139 pg/mL). Four variables were entered into a multivariate linear regression model predictive for serum N-terminal-pro B-type natriuretic peptide values: age, neoplastic edema volume, metastatic lesion, and the presence of a mass effect (whole model P < 0.0001; R(2) = 0.5555; adjusted R(2) = 0.5294).. Our data demonstrate that serum B-type natriuretic peptide levels are positively correlated to neoplastic brain edema in patients with a brain tumor and suggest a possible cerebral source for this phenomenon.
