A prospective study was performed to assess the use of plasma measurement of tumour necrosis factor (TNF), lymphotoxin alpha (LT alpha) and their soluble receptors (p55 and p75) for prognostic risk assignment in 61 patients with Hodgkin's disease. Plasma levels of TNF, p55 and p75, but not of LT alpha, were higher in Hodgkin's disease patients than in healthy controls. Plasma levels of TNF, p55 and p75 were associated with several prognostic factors for Hodgkin's disease, including those related to the host (age, performance status) and to the tumour (disease stage, extranodal site involvement, bulky tumour, serum levels of LDH and beta2-microglobulin, histology). Elevated plasma levels of TNF, p55 and p75 were also associated with several parameters reflecting an immune activation, including the presence of B symptoms, elevated serum levels of gammaglobulins, alkaline phosphatase and fibrinogen, as well as peripheral monocytosis, anaemia and low serum albumin levels. Finally, elevated TNF ligand receptor plasma markers were associated with a lower incidence of complete response to therapy and predicted shorter free-from-progression survival and overall survival of the patients. These results indicate that the plasma levels of TNF and its soluble receptors correlate with clinical features and outcome of patients with Hodgkin's disease.

Epstein-Barr virus is associated with several human malignancies including Burkitt's lymphoma, nasopharyngeal carcinoma, and Hodgkin's disease (HD). To examine the effect of Epstein-Barr virus nuclear antigen 1 (EBNA-1) in the pathogenesis of HD, we transfected the gene into the HD cell line L428. EBNA-1 expression was associated with significantly enhanced CD25 expression (interleukin 2 [IL-2]-receptor alpha chain) in transient and stably transfected L428 cells but did not affect the expression of IL-2 receptor beta and gamma chains. There was no up-regulation of the B-cell activation molecules CD23, CD30, CD39, CD40, CD44, CD71, and CD54 (intercellular adhesion molecule 1) or enhanced production of IL-6, IL-10, lymphotoxin alpha, and the soluble form of CD25. Stable EBNA-1-expressing L428 cells were nontumorigenic in SCID mice but showed enhanced lymphoma development in nonobese diabetic-SCID mice compared to mock-transfected cells.

Tumor necrosis factor (TNF) production and non-Hodgkin lymphoma (NHL) outcome was found to be related to the TNF(-308) polymorphism. To explore whether this could be linked to neighboring polymorphisms, we genotyped the TNF(-376,-308,-238,-163), lymphotoxin alpha (LTalpha)(+252), and HLA DRB1 alleles in 204 patients with NHL and 120 controls. TNF(-308A) was the only allele associated with higher TNF and its p55 and p75 receptors' levels (P =.009, P =.03, and P =.007) and lower complete remission rates (P =.006). Freedom from progression (FFP) and overall survival (OS) were shorter in patients with TNF(-308A) (P =.009 and P =.02), null HLA DRB1*02 allele (P =.007 and P =.14), or both genetic markers (P =.004 and P =.005). Multivariate analysis incorporating International Prognostic Index (IPI) identified TNF(-308A) (P <.0001, relative risk [RR] = 1.63; P <.0001, RR = 1.51) and null HLA DRB1*02 alleles (P =.015, RR = 1.18; P <.0001, RR = 1.25) as independent factors for FFP and OS. These results indicate the existence of at least 2 inherited factors involved in NHL outcome.

Tumor necrosis factor alpha (TNF-alpha) and lymphotoxin alpha (LT-alpha) have been shown to play an important role in the pathogenesis of limphoproliferative disease. Both cytokines regulate cell-survival and cell-death in leukemic cells. TNF-alpha and LT-alpha are highly produced in chronic lymphotic leukemia (CLL) and non-Hodgkin lymphoma (NHL) patients. Genetic polymorphism within regulatory regions of these cytokine genes can alter their expression levels. This study investigates an influence of TNF-alpha - 308 and LT-alpha + 250 polymorphisms on the activity of alkaline DNase in mononuclear cells of both patient groups as a potent biochemical marker of DNA fragmentation in the terminal phase of apoptosis. Study was performed on mononuclear cells of CLL and NHL patients. SNP were obtained by PCR-RFLP method. The activity of alkaline DNase was measured by spectrophotometric method. The study provided evidence of the influence of TNFG/A genotype and A alleles in the susceptibility to NHL, since the association of LT-alphaG/G genotype with CLL was observed. High-producing TNF-alpha - 308/LT-alpha + 250 heterozygous haplotype is associated with high NHL incidence. The investigated SNP influence the activity of alkaline DNase in CLL and NHL patients. The observed polymorphisms may modulate susceptibility of leukemic cells to apoptosis by way of DNase activity.
