Current knowledge of Epstein-Barr virus (EBV)-specific T-cell responses in the cerebrospinal fluid (CSF) of patients with EBV-related lymphoproliferative disease (EBV-LPD) in the central nervous system (CNS) is very limited. Here, we present two recipients of hematopoietic stem cell transplants with EBV-LPD in the CNS. EBV-specific CD8(+) T lymphocytes were(More)
OBJECTIVE Paraneoplastic neurological syndromes associated with anti-Hu antibodies (Hu-PNS) are mediated by a T-cell immune response that is directed against the Hu antigens. In pregnancy, many Th1-mediated autoimmune diseases such as rheumatoid arthritis and multiple sclerosis regress. We hypothesised that this decreased disease activity during pregnancy(More)
In paraneoplastic neurological syndromes (PNS) associated with small cell lung cancer (SCLC) and Hu antibodies (Hu-PNS), Hu antigens expressed by the tumour hypothetically trigger an immune response that also reacts with Hu antigens in the nervous system, resulting in tumour suppression and neuronal damage. To gain more insight into the hypothesized CD8+ T(More)
In paraneoplastic neurological syndromes associated with Hu-antibodies (Hu-PNS) an important role for cellular immunity is hypothesized. We characterized the cerebrospinal fluid (CSF) pleocytosis in Hu-PNS patients by assessing the major lymphocyte subsets by flow cytometry. The B cell subset in the CSF of Hu-PNS patients showed a significant absolute(More)
BACKGROUND Hypothetically, T cells are involved in the pathogenesis of paraneoplastic neurological syndromes associated with Hu-antibodies (Hu-PNS). OBJECTIVE To identify genetic risk factors for Hu-PNS and investigate the role of T cells. METHODS HLA-A, B, DRB1 and DQB1 alleles were compared in 53 Hu-PNS patients with 24 small-cell lung-cancer (SCLC)(More)
Lumbar juxta facet cysts (JFC) are an uncommon cause of radiculopathy. Spontaneous regression of symptomatic JFC has not often been reported. We describe 2 patients, a 59-year-old man and a 55-year-old man, with radiculopathy of the 5th lumbar nerve root due to a JFC at L4-5. The first patient recovered spontaneously. After 8 months, the JFC had clearly(More)
To detect HuD-specific T cells in patients with Hu-antibody associated paraneoplastic neurological syndromes (Hu-PNS), we used short-term stimulation assays with HuD protein spanning peptide pools (PSPP) with purities of at least 70% and found reproducible false-positive CD8+ T-cell responses in three of 127 individuals (two healthy controls and one Hu-PNS(More)
In paraneoplastic neurological syndromes (PNS) associated with small cell lung cancer (SCLC) and Hu antibodies, neuron-specific Hu antigens expressed by the tumour hypothetically trigger an immune response that cross-reacts with Hu antigens in the nervous system, resulting in tumour suppression and neuronal damage. To gain more insight into the hypothesized(More)
OBJECTIVE To determine the clinical features and presence in CSF of antineuronal antibodies in patients with pathologically proven autoimmune encephalitis derived from a cohort of patients with suspected Creutzfeldt-Jakob disease (CJD). METHODS The Dutch Surveillance Centre for Prion Diseases performed 384 autopsies on patients with suspected CJD over a(More)
