A 53-year-old man presented with bilateral cervical lymph node swelling and low fever. Swollen lymph node was biopsied, and diagnosed as nodular sclerosing Hodgkin's disease (HD). By combined radio- and chemotherapy, he went into complete remission. After 3 years, fever of 38-39.2 degrees C and lymph node swelling appeared in the para-aortic region and later became systemic. A biopsy was diagnosed as syncytial variant of HD with aid of immunohistochemistry on frozen sections. Large atypical mono- or binucleated cells reacted with anti-interleukin 6 (IL-6) antibody. The patient's disease progressed with fever, and he died 66 months after the onset of disease. A previous biochemical study showed that IL-6 displayed a real relation to the generation of fever. Therefore it is suggested that fever in this patient is related to IL-6.

Several cytokines including gamma-interferon, tumor necrosis factor alpha, interleukin 1 beta (IL-1 beta), and interleukin 6 (IL-6) are pyrogenic and can inhibit lipogenic processes. Because patients with lymphoma often suffer from fever, weight loss, and night sweats (B symptoms), the etiology of which is unknown, the authors investigated serum levels of these cytokines in normal volunteers and in patients with Hodgkin's and non-Hodgkin's lymphoma. Sixty serum samples from patients with Hodgkin's disease (28 patients) or non-Hodgkin's lymphoma (32 patients), as well as 20 samples from normal volunteers, were collected. The majority of patients had advanced (Stage III or IV) or relapsed disease. The assay for gamma-interferon was a specific and sensitive radioimmunoassay (lower limit of detection = 0.1 unit/ml); the assays for tumor necrosis factor alpha, IL-1 beta, and IL-6 were enzyme-linked immunoassays with lower limits of sensitivity of 10 pg/ml, 20 pg/ml, and 22 pg/ml, respectively. There were no statistically significant differences in gamma-interferon, tumor necrosis factor alpha, or IL-1 beta levels between lymphoma patients and normal subjects. In contrast, 20 of 57 patients (35%) with lymphoma as compared with 0 of 19 normal volunteers (0%) had detectable serum IL-6 levels (P < 0.005, chi 2 test). Interestingly, 17 of 29 lymphoma patients with B symptoms (59%) as opposed to 3 of 28 lymphoma patients without B symptoms (11%) had detectable serum IL-6 levels (P < 0.001, chi 2 test); the median IL-6 level was 28.9 pg/ml (B symptoms present) versus undetectable (no B symptoms) (P < 0.005, Mann-Whitney U test). Analyzing Hodgkin's and non-Hodgkin's lymphoma groups separately revealed similar results. IL-6 levels showed no significant correlation with time from diagnosis, beta 2-microglobulin, or lactate dehydrogenase levels. However, analysis by the method of Kaplan and Meir demonstrated that the median survival of Hodgkin's disease patients with detectable IL-6 levels (> or = 22 pg/ml) was 10 mo, whereas the median survival has not been reached at a median follow-up time of 37.5 mo in those patients with lower values (Wilcoxon P value = 0.0012). There were too few patients in each subset of non-Hodgkin's lymphoma to determine the correlation between IL-6 and survival but, considered as a single group, a statistically significant correlation was not found.(ABSTRACT TRUNCATED AT 400 WORDS)

Endogenous cytokines are aberrantly produced in many cancers and serve as autocrine growth factors or indicators of immune response to the tumors. Hence, cytokine deregulation is likely to participate in the development or evolution of the malignant process. Over the last few years, we have performed a series of studies, with the objective of measuring cytokine levels in tumors and correlating endogenous levels with phenotypic manifestations of cancer and with prognosis. Here, we present our analysis of serum interleukin 6 (IL-6) levels in lymphomas. We demonstrate that IL-6 levels are elevated in both relapsed and newly diagnosed Hodgkin's and non-Hodgkin's lymphoma and that these levels correlate with established prognostic features. Furthermore, in diffuse large cell lymphoma, IL-6 is an independent prognostic variable for both complete remission and failure-free survival. The molecular mechanisms underlying cytokine deregulation are now being investigated, with preliminary data from our laboratory suggesting heterogeneous genetic driving forces. In some cases, oncogene aberrations, particularly in the RAS system, may be responsible.

Among 39 posttransplant lymphoproliferative diseases (PTLD) in a cohort of 450 pediatric liver transplant recipients, 3 had a malignant lymphoma, unresponsive to arrest of immunosuppression and to gancyclovir, interferon, and anti-interleukin 6 antibodies. Lymphoma appeared 20, 46, and 96 months posttransplantation and 16, 43, and 90 months after primary Epstein-Barr virus infection. In one case, the patient had histological progression from plasmacytic hyperplasia PTLD, concomitant with symptomatic primary infection, to Burkitt-like lymphoma 43 months later. These three patients received five courses of chemotherapy, after a cyclophosphamide, doxorubicin, vincristine, and prednisone regimen for Burkitt-like or LH 89 scheme for Hodgkin-like PTLDs. Chemotherapy was well tolerated, and all three were free of disease and without immunosuppression 19, 14, and 4 months after chemotherapy. In Burkitt-like or Hodgkin-like PTLDs, immunomodulatory or antiviral drugs were inefficient. Chemotherapy is indicated and can be safely and successfully used. Long-term arrest of immunosuppression seems feasible without graft rejection.

Multicentric Castleman disease (MCD) is a distinct type of lymphoproliferative disorder associated with inflammatory symptoms and interleukin 6 (IL-6) dysregulation. In the context of human immunodeficiency virus (HIV) infection, MCD is associated with Kaposi sarcoma-associated herpesvirus, also called human herpesvirus type 8 (KSHV/HHV8). Within a prospective cohort study on 60 HIV-infected patients with MCD, and a median follow-up period of 20 months, 14 patients developed KSHV/HHV8-associated non-Hodgkin lymphoma (NHL): 3 "classic" KSHV/HHV8(+) Epstein-Barr virus-positive (EBV(+)) primary effusion lymphoma (PEL), 5 KSHV/HHV8(+) EBV(-) visceral large cell NHL with a PEL-like phenotype, and 6 plasmablastic lymphoma/leukemia (3/3 KSHV/HHV8(+) EBV(-)). The NHL incidence observed in this cohort study (101/1000 patient-years) is about 15-fold what is expected in the general HIV(+) population. MCD-associated KSHV/HHV8(+) NHL fell into 2 groups, suggesting different pathogenesis. The plasmablastic NHL likely represents the expansion of plasmablastic microlymphoma from the MCD lesion and progression toward aggressive NHL. In contrast, the PEL and PEL-like NHL may implicate a different original infected cell whose growth is promoted by the cytokine-rich environment of the MCD lesions.

The pathogenesis of Kaposi's sarcoma (KS) is better understood since the identification of the novel human herpesvirus 8 (HHV8), which can be found in all forms of KS. Viral oncogenesis and cytokine-induced growth, as well as some states of immunocompromise, contribute to its development. Several virally encoded genes--eg, bcl-2, interleukin 6, cyclin D, G-protein-coupled receptor, and interferon regulatory factor--provide key functions on cellular proliferation and survival. Growth promotion of KS is further stimulated by various proinflammatory cytokines and growth factors such as tumour necrosis factor a, interleukin 6, basic fibroblast growth factor, and vascular endothelial growth factor, resulting in a hyperplastic polyclonal lesion with predominant spindle cells derived from lymphoid endothelia. HHV8 has recently been discovered to escape HLA-class-I-restricted antigen presentation to cytotoxic T lymphocytes by increasing endocytosis of MHC class I chains from the cell surface, thus enabling latent infection and immune escape in primary and chronic infection. Multicentric Castleman's disease is a rare lymphoproliferative disorder of the plasma cell type, which has been reported in both HIV-seropositive and HIV-seronegative patients, and which frequently contains HHV8 DNA. Pleural effusion lymphoma, or body-cavity-based lymphoma, belongs to the group of non-Hodgkin B-cell lymphomas characterised by pleural, pericardial, or peritoneal lymphomatous effusions in the absence of a solid tumour mass. Pleural effusion lymphoma has an intermediate immunophenotype lacking B or T lymphocyte antigens and also belongs to the diseases associated with HHV8.

Hodgkin's disease appearing as, or associated with, fibrous thyroiditis has only been described rarely. We report the observation of a patient presenting with a goitre, fibrosis of the thyroid and adjacent structures, and hypothyroidism. The histological examination was compatible with fibrosclerotic thyroiditis. This diagnosis was reviewed 6 months later when the biopsy of a supraclavicular nodule that had subsequently appeared led to the diagnosis of a nodular-sclerosis type of Hodgkin's disease. The plasmatic levels of interleukin 6 (IL-6) and tumour necrosis factor alpha (TNF-alpha) were very high compared to the levels in healthy subjects (12 and 40 IU/l vs. 0.05 and 2.0 IU/l, respectively). These cytokine levels decreased when the initial illness was treated, and their normalization was associated with the disappearance of the cervical and thyroidal fibroses. A parallel in vitro study of these cytokines and of TNF-alpha receptors and IL-13 was performed. The results suggest a possible cause-and-effect relationship between IL-6 and IL-13 produced locally by the tumoral tissue and the development of cervical fibrosis.

Kaposi sarcoma-associated herpesvirus (KSHV) causes Kaposi sarcoma and is also associated with primary effusion lymphoma, a subset of diffuse large B-cell lymphomas, and multicentric Castleman disease. Because KSHV infection is endemic in sub-Saharan Africa, we sought to identify cases of KSHV-positive non-Hodgkin lymphomas (NHLs) and reactive lymphadenopathy in this region. One hundred forty-four cases (80 NHLs, 64 reactive lymph nodes) from the major pathology laboratory in Uganda were reviewed. One NHL was KSHV-positive, as indicated by staining for the viral latent nuclear antigen. This NHL was a diffuse large B-cell lymphoma in a 5-year-old boy. The tumor was also Epstein-Barr virus-positive. In addition, 2 reactive lymph nodes, both classified histologically as follicular involution, stained KSHV latent nuclear antigen-positive and thus most likely represent multicentric Castleman disease. In all 3 KSHV-positive cases, a minority of cells expressed KSHV viral interleukin 6, a biologically active cytokine homolog. In conclusion, we show that KSHV is rarely associated with lymphoproliferative disorders in sub-Saharan Africa. We describe the first case of a KSHV-positive NHL from this region; this case is also the first reported pediatric lymphoma associated with KSHV infection.

A 20-year-old man complained of fever, general lymphadenopathy, severe lumbago, and gynecomastia in January 2003. The diagnosis of Hodgkin lymphoma was confirmed by biopsy specimens of the right supraclavicular lymph node. The clinical stage was IIIB, and the prognostic score was 3. Plasma levels of interleukin 6 (IL-6) and vascular endothelial growth factor (VEGF) were elevated to 446 pg/mL, and 1,710 pg/mL,respectively. Six-course combination chemotherapy with the ABVD regimen was initiated,and a complete response (CR) was achieved. Clinical signs disappeared and plasma levels of IL-6 and VEGF decreased to 5.0 pg/mL and 100 pg/mL, respectively. The patient remained in CR as of December 2006. Elevated IL-6 and VEGF may be appropriate tumor markers for patients with Hodgkin lymphoma.

Castleman's disease is a primary infectious disease of the lymph node that causes local symptoms or a systemic inflammatory syndrome. Histopathology reveals a destroyed lymph node architecture that can range from hyaline-vascular disease to plasma-cell disease. Viral interleukin 6 (vIL-6) produced during the replication of human herpesvirus type 8 (HHV8) is the key driver of systemic inflammation and cellular proliferation. Stage progression of Castleman's disease results from switches between viral latency and lytic replication, and lymphatic and hematogenous spread. Multicentric plasma-cell disease in HIV-1 patients is associated with HHV8 infection. Polyclonal plasmablast proliferation escapes control in the germinal center with eventual malignant transformation into non-Hodgkin lymphoma. Surgery produces excellent results in unicentric disease, while multicentric disease responds to anti-CD20 therapy or IL-6 and chemotherapy. Lymphovascular endothelium and naive B cells are infectious reservoir-opening options for antiangiogenic and anti-CD19 strategies to enhance outcomes in patients with systemic disease.
