Donor Cell Chimerism Evaluation in Cerebrospinal Fluid by Short Tandem Repeat Analysis Following Allogeneic Hematopoietic Stem Cell Transplantation.

Summary of "Donor Cell Chimerism Evaluation in Cerebrospinal Fluid by Short Tandem Repeat Analysis Following Allogeneic Hematopoietic Stem Cell Transplantation."

Cerebrospinal fluid (CSF) cell count, morphology and flow cytometric evaluations are used to investigate central nervous system (CNS) involvement in leukemia/lymphoma. We performed CSF short tandem repeat (STR) analysis to monitor CSF chimerism status and evaluate for disease involvement in 11 asymptomatic pediatric allogeneic hematopoietic stem cell transplantation (HSCT) recipients with hemato-lymphoid neoplasms and high risk for or history of CNS involvement. Eighteen (64%) of the samples with median CSF cell count of 1/mm with 90% lymphocytes gave conclusive STR results, suggesting that this DNA-based method can be used in monitoring CSF chimerism status after HSCT with an acceptable yield.

Medical and Biotech [MESH] Definitions

Discharge of cerebrospinal fluid through a hole through the skull bone most commonly draining from the nose (CEREBROSPINAL FLUID RHINORRHEA) or the ear (CEREBROSPINAL FLUID OTORRHEA).

Tubes inserted to create communication between a cerebral ventricle and the internal jugular vein. Their emplacement permits draining of cerebrospinal fluid for relief of hydrocephalus or other condition leading to fluid accumulation in the ventricles.

Discharge of cerebrospinal fluid through the nose. Common etiologies include trauma, neoplasms, and prior surgery, although the condition may occur spontaneously. (Otolaryngol Head Neck Surg 1997 Apr;116(4):442-9)

Proteins in the cerebrospinal fluid, normally albumin and globulin present in the ratio of 8 to 1. Increases in protein levels are of diagnostic value in neurological diseases. (Brain and Bannister's Clinical Neurology, 7th ed, p221)

Manometric pressure of the CEREBROSPINAL FLUID as measured by lumbar, cerebroventricular, or cisternal puncture. Within the cranial cavity it is called INTRACRANIAL PRESSURE.
