    Abstract: We performed a pooled analysis of data on self-reported history of infections in relation to the risk of non-Hodgkin lymphoma (NHL) from 17 case-control studies that included 12,585 cases and 15,416 controls aged 16-96 years at recruitment. Pooled odds ratios (OR) and 95% confidence intervals (95% CI) were estimated in two-stage random-effect or joint fixed-effect models, adjusting for age, sex and study centre. Data from the 2 years before diagnosis (or date of interview for controls) were excluded. A self-reported history of infectious mononucleosis was associated with an excess risk of NHL (OR = 1.26, 95% CI = 1.01-1.57 based on data from 16 studies); study-specific results indicate significant (I(2) = 51%, p = 0.01) heterogeneity. A self-reported history of measles or whooping cough was associated with an approximate 15% reduction in risk. History of other infection was not associated with NHL. We find little clear evidence of an association between NHL risk and infection although the limitations of data based on self-reported medical history (particularly of childhood illness reported by older people) are well recognized.

    Abstract: Autoimmune conditions and immune system-related genetic variations are associated with risk of non-Hodgkin lymphoma (NHL). In a pooled analysis of 8,692 NHL cases and 9,260 controls from 14 studies (1988-2007) within the International Lymphoma Epidemiology Consortium, we evaluated the interaction between immune system genetic variants and autoimmune conditions in NHL risk. We evaluated the immunity-related single nucleotide polymorphisms rs1800629 (tumor necrosis factor gene (TNF) G308A), rs1800890 (interleukin-10 gene (IL10) T3575A), rs6457327 (human leukocyte antigen gene (HLA) class I), rs10484561 (HLA class II), and rs2647012 (HLA class II)) and categorized autoimmune conditions as primarily mediated by B-cell or T-cell responses. We constructed unconditional logistic regression models to measure associations between autoimmune conditions and NHL with stratification by genotype. Autoimmune conditions mediated by B-cell responses were associated with increased NHL risk, specifically diffuse large B-cell lymphoma (odds ratio (OR) = 3.11, 95% confidence interval (CI): 2.25, 4.30) and marginal zone lymphoma (OR = 5.80, 95% CI: 3.82, 8.80); those mediated by T-cell responses were associated with peripheral T-cell lymphoma (OR = 2.14, 95% CI: 1.35, 3.38). In the presence of the rs1800629 AG/AA genotype, B-cell-mediated autoimmune conditions increased NHL risk (OR = 3.27, 95% CI: 2.07, 5.16; P-interaction = 0.03) in comparison with the GG genotype (OR = 1.82, 95% CI: 1.31, 2.53). This interaction was consistent across major B-cell NHL subtypes, including marginal zone lymphoma (P-interaction = 0.02) and follicular lymphoma (P-interaction = 0.04).

    Abstract: We performed a pooled analysis of data on atopic disease and risk of non-Hodgkin lymphoma (NHL) from 13 case-control studies, including 13,535 NHL cases and 16,388 controls. Self-reported atopic diseases diagnosed 2 years or more before NHL diagnosis (cases) or interview (controls) were analyzed. Pooled odds ratios (OR) and 95% confidence intervals (95% CI) were computed in two-stage random-effects or joint fixed-effects models, and adjusted for age, sex, and study center. When modeled individually, lifetime history of asthma, flay fever, specific allergy (excluding hay fever, asthma, and eczema), and food allergy were associated with a significant reduction in NHL, risk, and there was no association for eczema. When each atopic condition was included in the same model, reduced NHL risk was only associated with a history of allergy (OR, 0.80; 95% CI, 0.68-0.94) and reduced R-cell NHL risk was associated with history of hay fever (OR, 0.85; 95% CI, 0.77-0.95) and allergy (OR, 0.84; 95% CI, 0.76-0.93). Significant reductions in B-cell NHL risk were also observed individuals who were likely to be truly or highly atopic-those with hay fever, allergy, or asthma and at least one other atopic condition over their lifetime. The inverse associations were consistent for the diffuse large B-cell and follicular subtypes. Eczema was positively associated with lymphomas of the skin; misdiagnosis of lymphoma as eczema is likely, but progression of eczema to cutaneous lymphoma cannot be excluded. This Pooled study shows evidence of a modest but consistent reduction in the risk of B-cell NHL associated with atopy. [Cancer Res 2009;69(16):6482-9]

    Abstract: Some autoimmune disorders are increasingly recognized as risk factors for non-Hodgkin lymphoma (NHL) overall, but large-scale systematic assessments of risk of NHL subtypes are lacking. We performed a pooled analysis of self-reported autoimmune conditions and risk of NHL and subtypes, including 29 423 participants in 12 case-control studies. We computed pooled odds ratios (OR) and 95% confidence intervals (CI) in a joint fixed-effects model. Sjogren syndrome was associated with a 6.5-fold increased risk of NHL, a 1000-fold increased risk of parotid gland marginal zone lymphoma (OR = 996; 95% CI, 216-4596), and with diffuse large B-cell and follicular lymphomas. Systemic lupus erythematosus was associated with a 2.7-fold increased risk of NHL and with diffuse large B-cell and marginal zone lymphomas. Hemolytic anemia was associated with diffuse large B-cell NHL. T-cell NHL risk was increased for patients with celiac disease and psoriasis. Results for rheumatoid arthritis were heterogeneous between studies. Inflammatory bowel disorders, type 1 diabetes, sarcoidosis, pernicious anemia, and multiple sclerosis were not associated with risk of NHL or subtypes. Thus, specific autoimmune disorders are associated with NHL risk beyond the development of rare NHL subtypes in affected organs. The pattern of associations with NHL subtypes may harbor clues to lymphomagenesis

    Abstract: There is inconsistent evidence that increasing birth order may be associated with risk of non-Hodgkin lymphoma (NHL). The authors examined the association between birth order and related variables and NHL risk in a pooled analysis (1983-2005) of 13,535 cases and 16,427 controls from 18 case-control studies within the International Lymphoma Epidemiology Consortium (InterLymph). Overall, the authors found no significant association between increasing birth order and risk of NHL (P-trend = 0.082) and significant heterogeneity. However, a significant association was present for a number of B- and T-cell NHL subtypes. There was considerable variation in the study-specific risks which was partly explained by study design and participant characteristics. In particular, a significant positive association was present in population-based studies, which had lower response rates in cases and controls, but not in hospital-based studies. A significant positive association was present in higher-socioeconomic-status (SES) participants only. Results were very similar for the related variable of sibship size. The known correlation of high birth order with low SES suggests that selection bias related to SES may be responsible for the association between birth order and NHL

    Notes: Using a haemolytic plaque assay for y-interferon (IFN-γ) secretion we found that in vitro Epstein-Barr virus (EBV) exposure of peripheral blood mononuclear cells from EBV immune individuals led to IFN-y secretion, which was apparent wiihin 6 h after virus coniact and peaked 12–24 h after induction. Live, ultraviolel-light-irradiaicd and heat-inactivated virions all caused IFN-γ secretion. In contrast, blood mononuclear cells from EBV non-immune adults or neonates could not be activated to IFN-y production by EBV.

    Notes: The clonal selection theory, as formulated by Burnet, predicts that a lymphocyte bearing receptors for a given antigen will, upon activation, produce antibody to that same antigen. This prediction has for the first time been quantitatively confirmed, by precursor frequency analysis of highly purified sheep erythrocyte antigen-binding cells (SRBC-ABC), isolated from the spleens of non-immune mice, by means of an LPS-driven limiting dilution micro-culture system. These precursor frequencies indicated that virtually every non-immune SRBC-ABC that was a precursor for the secretion of IgM (or IgG) was also a precursor for the secretion of SRBC-specific IgM (or SRBC-specific JgG), after correction for non-SRBC-ABC B cells contaminating the SRBC-ABC preparations. These data help to clarify the relationship between antigen-binding cells and the antigen-reactive cells of the clonal selection theory. In the course of making this observation, it was also shown that the precursor frequency of purified non-immune SRBC-ABC for IgG production was the same as that of unfractionated cells, whereas the precursor frequency for IgM production and LPS-induced thymidine incorporation were both lower in the ABC. The clone size estimates for IgM and IgG precursors in ABC and unfractionated cells all fell within a narrow range (1 to 2 doublings).

    Notes: Controversy concerning the immunologic role of antigen-binding cells (ABO has prompted us to attempt to quantitate the proportion of stimulable ABC, in immunized animals, which are precursors for cells producing antibody specific for the antigen bound. Using a lipopolysaccharide (LPS)-driven limiting dilution analysis system, the precursor frequency (PF) of cells secreting IgM and IgG and sheep erythrocyte (SRBQ-specific IgM and IgG was established for highly purified SRBC antigen-binding cell (SRBC-ABC) and unfractionated populations taken from CBA/J mouse spleens on days 5, 12 and 180 of the in vivo primary immune response to SRBC. At all these times, almost all SRBC-ABC spontaneously secreting immunoglobulin (Ig) secreted SRBC-specific Ig, and almost all precursors of Ig-secreting cells in the ABC populations were precursors of cells secreting specific anti-SRBC antibody. In SRBC-ABC populations, the PF for total and SRBC-specific Ig secretion was seen to decrease on days 5 and 12 after immunization and to increase to 3.5 to 7 times nonimmune levels 180 days after immunization. The absolute number of precursors, within the SRBC-ABC population, for the secretion of SRBC-specific Ig decreased on day 12 after immunization. In the unfractionated population, the PF for SRBC-specific Ig secretion temporarily increased after immunization, reaching peak levels 5 days (IgM) and 12 days (IgG) after immunization. These two changes may be related, representing the progress of stimulated cells out of the ABC pool as they lose receptors en roule to full maturation. The small clone sizes on days 5 and 12 indicate that ABC divide less in response to LPS when already engaged in a response to antigen. In contrast, the PF for total IgM and IgG secretion in the unfractionated population was not greatly affected by immunization.

    Description: The transferrin receptor 1 (TfR1) is an attractive target for Ab-mediated cancer therapy. We previously developed a mouse/human chimeric IgG3 Ab (ch128.1) targeting human TfR1, which exhibits direct in vitro cytotoxicity against certain human malignant B cells through TfR1 degradation and iron deprivation. ch128.1 also demonstrates exceptional antitumor activity against the B cell malignancy multiple myeloma (MM) in xenograft models of SCID-Beige mice bearing either disseminated ARH-77 or KMS-11 cells in an early disease setting. Interestingly, this activity is observed even against KMS-11 cells, which show no sensitivity to the direct cytotoxic activity of ch128.1 in vitro. To understand the contributions of the Fc fragment, we generated a ch128.1 mutant with impaired binding to FcRs and to the complement component C1q, which retains binding to the neonatal Fc receptor. We now report that this mutant Ab does not show antitumor activity in these two MM models, indicating a crucial role of the Fc fragment in the antitumor activity of ch128.1, which can be attributed to effector functions (Ab-dependent cell-mediated cytotoxicity, Ab-dependent cell-mediated phagocytosis, and/or complement-dependent cytotoxicity). Interestingly, in the KMS-11 model, complement depletion does not affect protection, whereas macrophage depletion does. Consistent with this observation, we found that ch128.1 induces Ab-dependent cell-mediated cytotoxicity and Ab-dependent cell-mediated phagocytosis against KMS-11 cells in the presence of murine bone marrow–derived macrophages. Finally, we found that ch128.1 therapy effectively increases survival in a late MM disease setting. Our results suggest that macrophages play a major role in ch128.1-mediated antitumor protection in our models and that ch128.1 can be effective against human B cell malignancies such as MM.
