In this report the association of autoimmunity and autoimmune syndromes with lymphoproliferative disorders (LPD) is described in 15 patients. Non-Hodgkin's lymphoma (NHL) developed in 10 patients, Hodgkin's disease (HD) in 3 and chronic lymphocytic leukemia (CLL) in two. In most instances clinical and laboratory phenomena preceded the development/diagnosis of these disorders. Manifestations ranged from the presence of autoantibodies in the serum to the presence of both ill defined or incomplete autoimmune syndromes including cold urticaria, Raynaud's phenomenon, cold agglutinin disease, thyroiditis, nephrotic syndrome and vasculitis to typical systemic lupus erythematosus (SLE), rheumatoid arthritis (RA) and even one of scleroderma. It is suggested that in some patients (in)complete clinical manifestations of autoimmunity may precede the development of lymphoid neoplasias. The link between autoimmunity and lymphoproliferative disorders is briefly discussed.

The experiment used 50 female NZB/W mice divided into 2 groups of 25 animals each. Beginning at the age of 3 weeks and up to 1 year the animals of the experimental group were given once in 2 weeks 104 U/injection of mouse interferon intraperitoneally; the animals of the control group received physiological saline according to the same schedule. At the age of 3 months and subsequently at 6-week intervals up to 1 year mice of the two groups were examined for blood serum antibodies to native DNA and double-stranded RNA. The presence of p30 antigen of mouse leukemia virus in the spleen and blood serum was determined by the competitive radioimmunoassay in mice of both groups at the age of 3 months but not later because immune complexes with virus-specific antibodies appeared to be formed. The difference in the average longevity of the animals between the experimental (425 +/- 25.6 days) and control (315 +/- 15.1 days) groups is statistically highly significant. At the age of 3 months mice of the experimental group had significantly lower mean tires of antibody to DNA than in the control group (12.3 +/- 8.1 and 56.1 +/- 9.7, respectively), subsequently no significant differences in the titres were observed. Similar data were obtained with regard to antibodies to double-stranded RNA in the animals under 6 months of age. Morphological signs of development of lupus-nephritis in control mice appeared in histological studies earlier and were more marked than in the treated mice. It is concluded that the autoimmune disease in NZB/W mice was successfully treated with interferon.

We describe a patient presenting with systemic lupus erythematosus (SLE) and concomitant low-grade (Ig) non-Hodgkin's lymphoma of the B cell type (B-NHL). Although the association of autoimmune disorder and lymphoma is well conceived, there is only scarce information available as to the simultaneous occurrence of both disease conditions in one patient. As in this patient diagnosis of Ig B-NHL was also based on the detection of a monoclonal population of CD5+ B lymphocytes, and given that the polyclonal expansion of CD5+ B cells has been previously reported in rheumatoid arthritis (RA), Sjogren's syndrome (SS) and single cases of SLE, the observations we made in this patient led us to discuss the role of the CD5+ population in the development of rheumatic disorders and concomitant lymphoid malignancy. Moreover, since impaired production rates of interleukin 3 (IL-3) and interleukin 4 (IL-4) have been associated with an abnormal expansion of CD5, lymphoma cells and seeing that soluble interleukin 2 receptor (sIL-2R) serum levels were found to be positively correlated with disease activity both in SLE and Ig B-NHL, these parameters were investigated and related to the patient's disease state throughout the entire clinical observation period.

Soluble Fas (sFas) in the serum is believed to be able to inhibit apoptosis of lymphocytes. It has been reported that the serum sFas level is increased in various diseases, including malignant lymphoma and systemic lupus erythematosus. We studied the association between sFas and the prognosis of patients with aggressive non-Hodgkin's lymphoma (NHL). Compared with normal controls, the serum sFas level was increased significantly in patients with aggressive NHL and adult T cell leukemia/lymphoma. Among patients with aggressive NHL, the complete remission rate was significantly decreased in the subgroup having high serum sFas levels. Both the overall survival rate and the disease-free survival (DFS) rate were significantly lower for this subgroup than for patients with low serum sFas levels. The 5-year survival rates estimated by the Kaplan-Meier method for patients with high and low serum sFas levels were 27.6% and 68.3%, respectively (P = 0.0001). The 5-year DFS rates estimated for patients with high and low serum sFas levels were 44.7% and 71.9%, respectively (log-rank test: P = 0.0023, and generalized Wilcoxon test: P = 0.0014). Among patients with a low and low-intermediate risk group according to the International Prognostic Index (IPI), the 5-year survival rates for low and high serum sFas subgroups were 72.8% and 42.0%, respectively, showing a significant difference (Wilcoxon test: P = 0.0163, log-rank test: P = 0.0115). Among patients with a high-intermediate and high risk group, the 5-year survival rates for low and high serum sFas subgroups were 51.6% and 17.4%, respectively, again showing a significant difference (Wilcoxon test: P = 0.0001, log-rank test: P = 0.0002). Multivariate analysis of a series of prognostic factors, including the five used to calculate the IPI, showed that the serum sFas level was an independent prognostic factor for the overall survival. Based on these results, a serum sFas level of 10 ng/ml or more can be considered to indicate a poor prognosis in patients with advanced NHL, and this finding may be useful for developing strategies for further treatment.

The objective of this study was to determine the frequency of oral, dental and periodontal findings in three different groups of immunocompromised patients and in a healthy control group, to evaluate whether there is a correlation between manifestations of disease and immunologic parameters. The survey included 46 patients with a diagnosis of systemic lupus erythematosus, 48 heart transplant recipients, and 53 adult patients suffering from acute leukemias. Fifty matched healthy subjects were used as a control group. Each patient had to answer questions on medical and dental health and underwent a thorough oral, dental and serological investigation. Oral mucosal lesions were found in nearly half of all immunocompromised patients (49.6%), but in only 26% of control patients. No significant associations were found between different types of oral lesions and the underlying cause of immunosuppression. Leukemia patients showed age-unrelated higher scores in periodontal indices (P<0.05). Laboratory parameters failed to be significant in the assessment of oral health.

Clinical applications of flow cytometry to certain diseases of the dog and cat are now possible. The utility of such applications for diagnosis, prognosis and follow-up are illustrated here by a number of examples: feline AIDS resulting from FIV infection, Leukocyte Adhesion Deficiency in Irish setters, deep pyoderma in German shepherds, Immune-mediated Thrombocytopenia, canine Systemic Lupus Erythematosus and Leishmaniasis, Leukemia and Lymphoma.

Natural killer (NK) cells are cytotoxic lymphocytes that substantially contribute to the therapeutic benefit of antitumor antibodies like Rituximab, a crucial component in the treatment of B-cell malignancies. In chronic lymphocytic leukemia (CLL), the ability of NK cells to lyse the malignant cells and to mediate antibody-dependent cellular cytotoxicity upon Fc receptor stimulation is compromised, but the underlying mechanisms are largely unclear. We report here that NK-cells activation-dependently produce the tumor necrosis factor family member 'B-cell activating factor' (BAFF) in soluble form with no detectable surface expression, also in response to Fc receptor triggering by therapeutic CD20-antibodies. BAFF in turn enhanced the metabolic activity of primary CLL cells and impaired direct and Rituximab-induced lysis of CLL cells without affecting NK reactivity per se. The neutralizing BAFF antibody Belimumab, which is approved for treatment of systemic lupus erythematosus, prevented the effects of BAFF on the metabolism of CLL cells and restored their susceptibility to direct and Rituximab-induced NK-cell killing in allogeneic and autologous experimental systems. Our findings unravel the involvement of BAFF in the resistance of CLL cells to NK-cell antitumor immunity and Rituximab treatment and point to a benefit of combinatory approaches employing BAFF-neutralizing drugs in B-cell malignancies.
