Chronic active Epstein-Barr virus (EBV) infection (CAEBV) is an EBV-associated lymphoproliferative disease characterized by repeated or sustainable infectious mononucleosis (IM)-like symptoms. EBV is usually detected in B cells in patients who have IM or Burkitt's lymphoma and even in patients with X-linked lymphoproliferative syndrome, which is confirmed to have vulnerability to EBV infection. In contrast, EBV infects T cells (CD4+ T, CD8+ T, and γδT) or NK cells mono- or oligoclonally in CAEBV patients...

Chemotherapy of East Coast fever, a lymphoproliferative cancer-like disease of cattle causing significant economic losses in Africa, is largely dependent on the use of buparvaquone, a drug that was developed in the late 1980's. The disease is caused by the tick-borne protozoan pathogen Theileria parva. Buparvaquone can be used prophylactically and it is also active against tropical theileriosis, caused by the related parasite Theileria annulata. Recently, drug resistance was reported in T. annulata, and could occur in T...

Purpose: Inducible caspase 9 ( iCasp9 ) is a cellular safety switch that can make T-cell therapy safer. The purpose of this phase I trial was to investigate the use of iCasp9 -transduced T-cell addback in adult patients undergoing haploidentical stem cell transplantation for high-risk hematologic malignancies. Patients and Methods: Patients undergoing myeloablative, CD34-selected haploidentical stem cell transplantation were treated with 0.5-1.0 × 106 /kg donor-derived iCasp9 -transduced T cells on day +25 or 26 post-transplant, with additional doses allowed for disease relapse, infection, or mixed chimerism...

Marek's Disease is a lymphoproliferative disease of chickens caused by Marek's Disease Virus. Similar to other herpesviruses, Marek's Disease Virus (MDV) encodes its own small non-coding regulatory RNAs termed microRNAs (miRNAs). We previously found that the expression profile of these viral miRNAs is affected by vaccination with Herpesvirus of Turkeys (HVT). To further characterize miRNA-mediated gene regulation in MDV infections, in the current study we examine the impact of HVT vaccination on cellular miRNA expression in MDV-infected specific-pathogen-free (SPF) chickens...

Idiopathic multicentric Castleman disease (iMCD) is a rare lymphoproliferative disorder. The anti-interleukin(IL)-6 therapy siltuximab is not available everywhere, and is not effective for over half of patients. Alternative treatment approaches are urgently needed. In the first iMCD clinical trial directed against a target other than IL-6 signaling, we investigated thalidomide-cyclophosphamide -prednisone (TCP) regimen in newly diagnosed iMCD patients. This single-center, single-arm, phase 2 study enrolled 25 newly diagnosed iMCD patients between June 2015 and June 2018 (registered on ClinicalTrials...

In Parkinson's Disease (PD), the peripheral changes in the functional capacity and redox state of immune cells has been scarcely investigated, especially in the early PD stages. Aging is a risk factor for PD, and the age-related impairment of the immune system, based on a chronic-oxidative stress situation, is involved in the rate of aging. We analyzed several functions in isolated peripheral blood neutrophils and mononuclear cells from PD stage 2 patients, and compared the results to those in healthy elderly and adult controls...

There is a significant overlap between intestinal lymphoproliferative disorders (LPDs) and inflammatory conditions of the intestine, including inflammatory bowel disease (IBD), in clinical, endoscopic, or histologic appearance, leading to diagnostic challenges. We report two cases of monomorphic epitheliotropic intestinal T-cell lymphoma (MEITL) that were initially considered to be ulcerative colitis (UC) and lymphocytic colitis, respectively. Both patients presented with diarrhea and abdominal pain. Colonoscopy revealed hyperemia and scattered shallow ulcerations in the colon, without obvious mass...

Due to the increasing role of endosonography [endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) and esophageal ultrasound-guided fine needle aspiration (EUS-FNA)] in the diagnosis of several lung diseases, the knowledge of technical aspects is mandatory to optimize the success of the procedure. Among those technicalities related to the procedure, the choice of a needle over another one-either in terms of dimension and type-may have a role in the diagnostic process, especially in some diseases such as lymphoproliferative disorders...

BACKGROUND AND AIM: Epstein-Barr virus (EBV) is a proposed trigger in the etiopathogenesis of inflammatory bowel disease (IBD) and is associated with lymphoproliferative diseases. Nevertheless, testing for EBV DNA in the intestinal mucosa and screening for EBV infection before initiation of a drug therapy are not routinely performed. The aim of this article is to increase awareness of the relevance of EBV infection in specific clinical situations. METHODS: In this short communication, we describe the disease course of three IBD patients with EBV infection, varying from EBV reactivation during disease flare up to a trigger of EBV-related mucocutaneous ulcer (EBV-MCU) and haemophagocytic lymphohistiocytosis (HLH)...

Although anti-TNFα agents have revolutionized the treatment of many inflammatory diseases, various concerns have been reported regarding the risks of cancer development, as well as acceleration of the progression of subclinical, pre-existing malignancies. In this case series we investigated the provocative effect of anti-TNFα drugs in the development of cutaneous mycosis fungoides (MF)-like lymphoproliferative reactions. We describe 5 patients aged between 25-63 diagnosed with autoimmune disorders (psoriatic arthritis- one patient, Crohn's disease- one patient and ankylosing spondylitis- three patients) who received anti-TNFα agents before the development of a cutaneous lymphoproliferative reaction...

Pulmonary nodular lymphoid hyperplasia is an uncommon reactive lymphoproliferative disorder that presents as an asymptomatic lung mass. The histopathologic diagnosis of pulmonary nodular lymphoid hyperplasia may be challenging because of its morphologic overlap with other diseases, such as extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue and immunoglobulin G4-related sclerosing disease. Despite the similarities, there are distinctive morphologic and phenotypic features that allow for the correct diagnosis in the majority of cases...

PURPOSE: Cutaneous T cell lymphomas (CTCL), encompassing a spectrum of T-cell lymphoproliferative disorders involving the skin, have collectively increased in incidence over the last 40 years. Sézary syndrome (SS) is an aggressive form of CTCL characterized by significant presence of malignant cells in both the blood and skin. The guarded prognosis for SS reflects a lack of reliably effective therapy, due in part to an incomplete understanding of disease pathogenesis. METHODS: Using single-cell sequencing of RNA and the machine-learning reverse graph embedding approach in the Monocle package, we defined a model featuring distinct transcriptomic states within SS...

INTRODUCTION: Kimura disease (KD) is a chronic lymphoproliferative disorder of unknown etiology that affects the skin and lymph nodes, mostly observed in males of Asian descent. The natural history of asymptomatic epiglottal KD remains unknown. This rare site of KD is often only diagnosed when tumor growth starts to obstruct the upper airways. OBSERVATION: A 34-year-old North African male presented with fatigue and multiple, slowly progressive, fluctuating skin nodules in the right mandibular and retroauricular regions...

Pediatric intractable autoimmune hepatitis is rare and may be responsible for acute liver failure. Mutations in the itchy E3 ubiquitin protein ligase ( ITCH ) gene (located on chromosome 20q11.22) can lead to a deficiency of the encoded protein, resulting in increased T-cell activity with lack of immune tolerance and manifestation of a complex systemic autoimmune disease. A 1-year-old girl of consanguineous parents received a liver transplant (LT) because of acute liver failure attributed to a drug-induced hypereosinophilic syndrome with positive liver-kidney-mikrosome-2 antibodies...

Chronic active Epstein-Barr virus infection (CAEBV) is one of the Epstein-Barr virus (EBV)-positive T- or NK-cell lymphoproliferative diseases. It is characterized by clonal proliferation of EBV-infected T or NK cells and their infiltration into systemic organs, leading to their failure. Inflammatory symptoms, fever, lymphadenopathy and liver dysfunction are main clinical findings of CAEBV. EBV itself contributes to the survival of the host cells via induction of CD40 and CD137 expression and constitutive activation of NF-κB...

Hepatitis C virus (HCV) is a global population problem due to its high prevalence, usually late diagnosis, the difficulties of treatment. In the prognosis of patients with HCV not only hepatic, but increasingly frequent of extrahepatic HCV manifestations, such as mixed cryoglobulinemia (CG), are important. Mixed CG is currently considered as a B-cell benign lymphoproliferative disorders. The role of HCV virus in the pathogenesis of lymphoproliferative diseases is confirmed by a large number of epidemiological studies, as well as by the effectiveness of antiviral therapy in patients with non-Hodgkin's lymphoma (NHL)...
