Systemic Epstein-Barr virus-positive T-cell lymphoproliferative childhood disease (EBV+ T-LPD) is extremely rare. Primary acute or chronic active Epstein-Barr virus infection triggers EBV+ T-LPD's onset and the disease involves clonal proliferation of infected T-cells with activated cytotoxic phenotype. The adult-onset EBV+ T-LPD (ASEBV+ T-LPD) is even rarer and needs to be extensively studied. Read More

We here report for the first time that low levels of interleukin (IL)-10 do not exclude lymphomatous meningitis (LM) in B-cell lymphoproliferative disorders (CLPD). Unexpectedly, IL-10 levels and IL-10:IL-6 ratio in CLPD differed from the levels observed in diffuse large B-cell lymphoma (DLBCL). We report the usefulness of adding the IL-10:IL-6 ratio in order to potentially reveal more aggressive lymphomas: either a transformation or an association with another "hidden" lymphoma such as primary CNS lymphoma (PCNSL).

The term monoclonal gammopathy of renal significance (MGRS) was introduced by the International Kidney and Monoclonal Gammopathy Research Group (IKMG) in 2012. The IKMG met in April 2017 to refine the definition of MGRS and to update the diagnostic criteria for MGRS-related diseases. Accordingly, in this Expert Consensus Document, the IKMG redefines MGRS as a clonal proliferative disorder that produces a nephrotoxic monoclonal immunoglobulin and does not meet previously defined haematological criteria for treatment of a specific malignancy.

Primary cutaneous CD30 lymphoproliferative diseases (LPDs) comprise a range of diseases (LyP, pcALCL, and borderline lesions) with broad histologic and phenotypical characteristics, although they all share the common feature of a favorable prognosis notwithstanding histology suggestive of a high-grade lymphoma. Given their cytomorphologic similarities, accurate diagnosis and workup are needed to differentiate these distinct entities in order to best use novel biologic therapies and avoid aggressive overtreatment. Moreover, although CD30 LPDs have a favorable prognosis, secondary malignancies should be considered as part of the initial evaluation, and patients should have ongoing surveillance. Read More

Purpose Of Review: Since its initial approval in 1997, rituximab has revolutionized the treatment of CD20-positive lymphoproliferative disorders. Now, over two decades later, second-generation molecules are emerging that may have key biological advantages compared to rituximab, as well as biosimilars that may be more cost-effective. Clinicians, health policy makers, and payers will now need to critically appraise the available evidence for these competitors and decide which anti-CD20 to use. Read More

The latent state is a critical component of all herpesvirus infections, and its regulation remains one of the most active areas of Epstein-Barr Virus (EBV) research. In particular, identifying environmental factors that trigger EBV reactivation into a virus-productive state has become a central goal in EBV latency research. Recently, a category of chemicals known as inducers of the endoplasmic reticulum unfolded protein response (UPR) have been shown to trigger EBV lytic reactivation in various established EBV-associated lymphoma cell lines.

The identification of hepatitis C virus (HCV) occurred in 1989, and soon thereafter, it was recognized that there was a higher prevalence of anti-HCV seropositivity in patients with end-stage renal disease (ESRD) when compared to the general population. Multiple extrahepatic manifestations have been associated with HCV infection in patients with ESRD; these include an increased prevalence and risk of cardiovascular complications, insulin resistance, diabetes mellitus, and lymphoproliferative disorders. Infection with HCV has also been associated with an increased relative risk of mortality in the ESRD patient when contrasted to those patients without infection. Read More

The interaction between pituitary hormones, GH - PRL, and Growth Factors, GF, plays a fundamental role in the physiological and neoplastic mechanisms of growth, the latter using these factors to a much greater extent compared to the former, with a direct dose-dependent effect on the speed of local or metastatic expansion. In hormone-dependent tumours, the respective male and female sex hormones interact with GH - PRL - GF to sustain the expansion of the tumour. We carried out a review of the literature on the relationship between the expression of GH and GHR in tumour tissues compared to healthy tissues, and on the correlation between this expression and tumour aggressiveness.

Cutaneous T-cell lymphomas (CTCLs) are a group of non-Hodgkin's lymphomas that present in the skin. In early-stage disease, the course is generally chronic and indolent; however, in advanced stages of disease, therapies rarely provide long-lasting responses, and the only potential curative therapy is allogeneic hematopoietic stem-cell transplantation. This has led to the search for novel targeted therapies to better treat more advanced stages of CTCLs that cannot be controlled by typical treatment regimens. Read More
