Castleman's disease (CD) is a rare lymphoproliferative disorder that has multiple histologic patterns, as well as two distinct clinical forms: unicentric or multicentric. Multicentric Castleman's disease (MCD) may have mild symptoms in some cases, but in others it can progress to severe pancytopenia, life-threatening infection, secondary malignancy, multiorgan failure, or death. Recent research has determined that the etiology of the disease signs and symptoms is related to elevated cytokines, including interleukin 6 (IL-6)...

This is a case presentation of a HHV8-positive multicentric Castleman's disease (MCD) of plasma cell type. The patient failed to respond to combined immunosuppressive therapy and monoclonal anti-CD20 therapy. Interestingly, administration of anti-IL-6R antibody stabilized the disease and resulted in clearance of HHV8 from the involved lymph nodes.

Kaposi sarcoma-associated herpesvirus (KSHV) is linked with the development of Kaposi sarcoma and the B lymphocyte disorders primary effusion lymphoma (PEL) and multi-centric Castleman disease. T cell immunity limits KSHV infection and disease, however the virus employs multiple mechanisms to inhibit efficient control by these effectors. Thus KSHV-specific CD4+ T cells poorly recognize most PEL cells and even where they can, they are unable to kill them. To make KSHV-infected cells more sensitive to T cell control we treated PEL cells with the thymidine analogue azidothymidine (AZT), which sensitizes PEL lines to Fas-ligand and TRAIL challenge; effector mechanisms which T cells use...

Castleman's disease (CD) also known as angiofollicular lymph node hyperplasia represents a group of uncommon non-clonal lymphoproliferation. We herein report a case of CD associated with carcinoma of the gall bladder. To the best of our knowledge, it is the first of its kind and has not been reported in the past. The hypothesis regarding the aetiopathogenesis of CD is that it is associated with interleukin-6 surges. This may be explained by the overproduction of IL-6 by tumour cells or IL-6 production due to a long-standing/smouldering localised inflammatory response...

Criminal prosecutions of individuals in the asbestos industry are reviewed, particularly the case of asbestos owner-executive Stephan Schmidheiny. Italian courts sentenced Schmidheiny to sixteen to eighteen years in jail for creating an environmental disaster causing three thousand deaths. The convictions were overturned on a technicality, and a murder case against Schmidheiny has started. His firm, Eternit, made asbestos-cement building products in many countries. Schmidheiny directed a cover-up that the Italian Court of Appeal blamed for delaying the ban of asbestos in Italy by ten years...

Castleman disease (CD), a benign lymphoproliferative disorder that affects lymph nodes, is uncommon in children, with only approximately 100 cases published. Although 23% of pediatric CD cases are found in the neck, there is no substantial reported percentage found in the salivary glands, especially the submandibular salivary gland (SMSG). A pediatric case of CD involving the SMSG is reported because of its extreme rarity.

Kaposi's sarcoma herpesvirus (KSHV) is the etiologic agent of Kaposi's sarcoma (KS) as well as two lymphoproliferative diseases, primary effusion lymphoma and multicentric Castleman's disease. KSHV encodes viral proteins, such as K1, that alter signaling pathways involved in cell survival. Expression of K1 has been reported to transform rodent fibroblasts, and K1 transgenic mice develop multiple tumors, suggesting that K1 has an important role in KSHV pathogenesis. We found that cells infected with a KSHV virus containing a WT K1 gene had a survival advantage under conditions of nutrient deprivation compared to cells infected with KSHV K1 mutant viruses...

Castleman's disease (CD) is a heterogeneous lymphoproliferative disorder of unknown aetiology. Mostly, this disorder is seen in immunocompromised hosts. It is known to be associated with systemic disorders like HIV, HHV-8, lymphoma, and Kaposi sarcoma. As of today, the clinical behaviour and outcome of CD in immunocompetent host remains suboptimally studied. We analyzed consecutively treated cases of CD presented to our centre in last 12 years. Case record files were studied for patient's characteristics, clinical presentation, baseline laboratory and pathologic parameters, therapy and outcome...

Kaposi's sarcoma-associated herpesvirus (KSHV) is the major etiologic agent of Kaposi's sarcoma, primary effusion lymphoma, and multicentric Castleman's disease. Recent studies have indicated that KSHV can be detected at high frequency in patient-derived bladder cancer tissue and might be associated with the pathogenesis of bladder cancer. Bladder cancer is the second most common cancer of the genitourinary tract, and it has a high rate of recurrence. Because drug resistance is closely related to chemotherapy failure and cancer recurrence, we investigated whether KSHV infection is associated with drug resistance of bladder cancer cells...

TAFRO syndrome is a systemic inflammatory disorder manifesting as thrombocytopenia; anasarca including pleural effusion and ascites; fever; renal insufficiency; and organomegaly including hepatosplenomegaly and lymphadenopathy. Its onset may be acute or sub-acute, but its etiology remains unknown. Although several clinical and pathological characteristics of TAFRO syndrome resemble those of Castleman's disease, other specific features can differentiate between the two. Some patients have been successfully treated with glucocorticoids and/or immunosuppressants including cyclosporin A, tocilizumab and rituximab, whereas others are refractory to treatment, eventually succumbing to the disease...

: Kaposi's sarcoma-associated herpesvirus (KSHV) is a gammaherpesvirus that has been associated with primary effusion lymphoma, multicentric Castleman's disease, as well as its namesake Kaposi's sarcoma. As a gammaherpesvirus, KSHV is able to acutely replicate, enter latency, and reactivate from this latent state. A key protein involved in both acute replication and reactivation from latency is the replication and transcriptional activator (RTA) encoded by the gene Orf50. RTA is a known transactivator of multiple viral genes allowing for it to control the switch between latency and virus replication...

Kaposi's sarcoma-associated herpesvirus (KSHV) is associated with formation of Kaposi's sarcoma, multicentric Castleman's disease and primary effusion lymphoma. Replication and transcription activator (RTA) genes are expressed upon reactivation of KSHV, which displays a biphasic life cycle consisting of latent and lytic replication phases. RTA protein expression results in KSHV genome amplification and successive viral lytic gene expression. Transcriptional activity of viral lytic genes is regulated through epigenetic modifications...

TAFRO syndrome is a rare constellation of symptoms: thrombocytopenia, anasarca, reticulin fibrosis of the bone marrow, renal dysfunction, and organomegaly. Its pathogenesis involves an excessive and inappropriate cytokine storm, most notably from IL-6, causing multiorgan failure; however, its etiology is undetermined. Starting in 2012, TAFRO syndrome was first identified in Japan as an atypical variant of Castleman's disease. Previous reports include various different treatment protocols with inconsistent survival outcomes...
