In a study aimed at correlating cytokine levels in synovial fluid with the pathology of rheumatoid arthritis (RA), tumour necrosis factor alpha, interleukin 1 beta and interferon gamma were immunoassayed in 27 patients with RA, 16 patients with other arthritides, 23 with osteoarthritis, 13 patients with trauma, and 18 patients at necropsy without(More)
The present prospective multicentre trial investigated whether topotecan, given at a starting dose of 1.25 mg.m(-2) with individual dose adjustment, can improve safety in patients with relapsed/refractory small cell lung cancer without loss of efficacy. Patients received topotecan intravenously on days 1-5, every 21 days, for up to six courses. In the(More)
OBJECTIVE To investigate the presence of the Epstein-Barr virus (EBV) in rheumatoid arthritis (RA) synovium and its correlation with the HLA genotype in an attempt to elucidate the role of EBV in the pathogenesis of RA. METHODS EBV DNA/RNA was investigated by polymerase chain reaction (PCR) analysis of synovial tissue from 84 patients with RA and from 81(More)
A sensitive and specific method to monitor suppression of cytomegalovirus (CMV) replication is essential in patients treated with ganciclovir after allogeneic bone-marrow transplantation. In this study, antiviral therapy of eighteen episodes of symptomatic CMV infection in 15 such patients were followed up clinically and by virus culture and polymerase(More)
OBJECTIVE To compare the expression of the cyclooxygenase (COX) isoforms, COX-1 and COX-2, in synovial tissue samples between patients with inflammatory arthritis (i.e., rheumatoid arthritis [RA], ankylosing spondylitis [AS], or psoriatic arthritis [PsA]) and patients with osteoarthritis (OA). METHODS Paraffin-embedded sections of synovial tissue from(More)
Twenty-eight patients undergoing bone marrow transplantation (BMT) were followed-up at weekly intervals from day -10 to discharge from hospital after BMT for human cytomegalovirus (HCMV) infection using polymerase chain reaction (PCR), slot-blot hybridization, and conventional virus culture. High specificity of the PCR assay applied could be shown by(More)
The clinical course of a 56-year-old female patient with Sweet's syndrome (SS) preceded by a myelodysplastic syndrome (MDS) is described. During the acute phase of the disease with high remittent fever, painful skin lesions and maximal leucocytosis IL-6 and G-CSF serum levels were extremely high, while TNF-alpha was only slightly elevated and(More)
In spite of differences in etiology, RA and OA lead to astonishingly similar synovitic alterations. Fibroblastic transformation of the synovial membrane and an increase in monocytes constitute a rare but highly characteristic feature of RA. Monocytes synthesize factor (F) XIII, implying that FXIII (a and s) in synovial tissue might help to differentiate(More)
Recent clinical observations support the hypothesis that persistent parvovirus B19 is a triggering factor of rheumatoid arthritis (RA) in certain genetically predisposed individuals. If this hypothesis is correct, a number of RA patients may exhibit parvovirus B19 DNA in their synovial membranes. We tested the synovial tissue and peripheral blood leukocytes(More)
We investigated 86 synovial membranes from patients suffering either from rheumatoid arthritis (RA) or osteoarthritis (OA). Iron deposits in the synovial membrane were stained by the Prussian blue reaction, and the amount of stained iron was quantitatively assessed by microscope photometry. We found a statistically significant increase in iron deposits in(More)
