Psoriasis is a chronic inflammatory skin disorder associated with several comorbidities including atherosclerosis. Disease mechanisms that may affect both psoriasis and atherosclerosis include activation of T helper 1 and T helper 17 cells. Imiquimod application is an established mouse model of psoriasis-like skin inflammation. The cardiac glycoside digoxin inhibits the master transcription factor of T helper 17 differentiation, retinoid acid receptor-related orphan nuclear receptor γt, and attenuates interleukin-17-dependent pathologies in mice...

BACKGROUND: Myelofibrosis (MF) is a life-shortening complication of myeloproliferative neoplasms associated with ineffective hematopoiesis, splenomegaly, and progressive bone marrow (BM) fibrosis. The oral Janus kinase (JAK) 1/JAK2 inhibitor ruxolitinib has been shown to improve splenomegaly, symptom burden, and overall survival in patients with intermediate-2 or high-risk MF compared with placebo or best available therapy (BAT). METHODS: The effects of ruxolitinib therapy for up to 66 months on BM morphology in 68 patients with advanced MF with variable BM fibrosis grade were compared with those in 192 matching patients treated with BAT...

Primary myelofibrosis (PMF) is a chronic clonal myeloid disorder. Together with essential thrombocythemia (ET) and polycythemia vera (PV), it belongs to a group of Philadelphia chromosome-negative myeloproliferative neoplasms. An integral part of laboratory tests carried out in this disease group is detecting the presence of mutations in the Janus kinase 2 gene at position 617 (JAK2 V617F) and in the gene encoding for the receptor for thrombopoietin (myeloproliferative leukemia virus oncogene, MPL) found in approximately 60% of PMF patients...

In severe cases of pancytopenia with subsequent infections due to long-term untreated Felty's syndrome, the initiation of immunosuppressive treatment with sole prednisone (1 mg/kg iv ) should be considered, despite that, the low neutrocytes count would make one physician hesitant. A full resolution of whole blood count within 3 weeks and a 30% reduction in spleens sized was noted.

BACKGROUND: Chronic lymphocytic leukemia and chronic myeloid leukemia are the most common types of adult leukemia. However, it is rare for the same patient to suffer from both. Richter's transformation to diffuse large B-cell lymphoma is frequently observed in chronic lymphocytic leukemia. Purine analog therapy and the presence of trisomy 12, and CCND1 gene rearrangement have been linked to increased risk of Richter's transformation. The coexistence of chronic myeloid leukemia and diffuse large B-cell lymphoma in the same patient is extremely rare, with only nine reported cases...

Importance: Myelofibrosis is a hematologic malignancy characterized by splenomegaly and debilitating symptoms. Thrombocytopenia is a poor prognostic feature and limits use of Janus kinase 1 (JAK1)/Janus kinase 2 (JAK2) inhibitor ruxolitinib. Objective: To compare the efficacy and safety of JAK2 inhibitor pacritinib with that of best available therapy (BAT), including ruxolitinib, in patients with myelofibrosis and thrombocytopenia. Design, Setting, and Participants: For this phase 3 randomized international multicenter study-the PERSIST-2 study-of pacritinib vs BAT, 311 patients with myelofibrosis and platelet count 100 × 109/L or less were recruited for analysis...

Polycythemia vera (PV) is the most common myeloproliferative neoplasm (MPN), the ultimate phenotype of the JAK2 V1617F mutation, the MPN with the highest incidence of thromboembolic complications, which usually occur early in the course of the disease, and the only MPN in which erythrocytosis occurs. The classical presentation of PV is characterized by erythrocytosis, leukocytosis, and thrombocytosis, often with splenomegaly and occasionally with myelofibrosis, but it can also present as isolated erythrocytosis with or without splenomegaly, isolated thrombocytosis or isolated leukocytosis, or any combination of these...

We report a case of a 45-year-old male who presented with a headache, fever, vomiting, somnolence, and difficulty walking for 10 days. His cerebrospinal fluid studies revealed cryptococcal meningitis. Chest and abdominal computed tomography (CT) scans showed splenomegaly along with mediastinal, retroperitoneal and inguinal lymphadenopathy. CD4 count turned out to be 208 μL-1 . Human immunodeficiency virus (HIV) testing, serum protein electrophoresis, serum light chains and quantitative immunoglobulins were non-diagnostic and CD4 lymphopenia was attributed to acute infection...

This document updates the recommendations on the management of Philadelphia chromosome-negative myeloproliferative neoplasms (Ph-neg MPNs) published in 2011 by the European LeukemiaNet (ELN) consortium. Recommendations were produced by multiple-step formalized procedures of group discussion. A critical appraisal of evidence by using Grades of Recommendation, Assessment, Development and Evaluation (GRADE) methodology was performed in the areas where at least one randomized clinical trial was published. Seven randomized controlled trials provided the evidence base; earlier phase trials also informed recommendation development...

INTRODUCTION: There are 7 designated conditions under the category of myeloproliferative neoplasms (MPN), including chronic myelogenous leukemia (CML) and classical MPN, that is, polycythemia vera (PV), essential thrombocythaemia (ET), and primary myelofibrosis (PMF). Recently, reports about Philadelphia and JAK2 V617F-positive MPN cases have been described in literature. The coexistence of different molecular defects may change the clinical and laboratory manifestation of MPN and may result in an inappropriate interpretation of the response to treatment with tyrosine kinase inhibitors in CML patients...

Known as a selective δ1 opioid receptor (DOR1) antagonist, the 7-benzylidenenaltrexone (BNTX) is also a DOR1-independent immunosuppressant with unknown mechanisms. Here we investigated if BNTX could be beneficial for diseased MRL/lpr lupus mice. We treated mice with 0.5, 2, 5 or 10 mg/kg/day of BNTX for 2 weeks. At as low as 2 mg/kg/day, BNTX significantly improved splenomegaly and lymphadenopathy. Notably, B cell numbers, particularly autoreactive plasma cells, were preferentially reduced; moreover, BNTX enhanced surface expression of FcγRIIB, an immune complex (IC)-dependent apoptotic trigger of B cells...

This study investigated the susceptibility of American singer canaries ( Serinus canaria) to West Nile virus (WNV) infection. Adult canaries were inoculated with 105 , 102 , and 101 plaque forming units (PFU) of WNV. All birds became infected and mortality occurred by 5 days postinoculation. The load of viral RNA as determined by RT-qPCR was dose dependent, and was higher at all doses than the level of viral RNA detected in American crows ( Corvus brachyrhynchos) challenged with 105 PFU of WNV. In a subset of birds, viremia was detected by virus isolation; canaries inoculated with 101 PFU of WNV developed viremia exceeding 1010 PFU/mL serum, a log higher than American crows inoculated with 105 PFU of virus...

Adult T-cell leukemia-lymphoma (ATLL) is caused by human T-cell lymphotropic virus type 1 (HTLV-1) and little is known about ATLL endemic to the Caribbean basin and Latin America, designated as western ATLL (W-ATLL). Due to extensive systemic involvement and nonspecific clinical presentation, the initial diagnosis in this cohort can be very challenging. We have diagnosed 60 patients with W-ATLL over a 14-year period. ATLL involves the peripheral blood, bone marrow, and cerebrospinal fluid (CSF) in 98, 87, and 52% cases, respectively; while lymphadenopathy, pulmonary infiltrates, splenomegaly, and hepatomegaly was present in 90, 82, 48, and 45% patients, respectively...
