Immune thrombocytopenia (ITP) is an autoimmune disease characterized by dysregulation of T cells. Programmed death (PD) 1 and programmed ligand (PD-L1) are cosignaling molecules, the major role PD-1 pathway inhibition self-reactive cells to protect against diseases. We measured levels serum soluble PD (sPD-1) PD-L1 (sPD-L1) in 67 patients with ITP (24 newly diagnosed [ndITP], 43 chronic [cITP]) 21 healthy controls (HCs). determined decreased sPD-1 both ndITP cITP when compared HC. Moreover,...

The involvement of the ovary in lymphomatous process is rare. Such an may occur 2 ways, primary or secondary. We report 5 cases ovarian non-Hodgkin's lymphoma, with 3 which primarily arising ovaries. Ovarian lymphoma can mimic more frequently occurring tumors including advanced epithelial carcinoma and radical surgery be performed instead a biopsy. immunophenotypic clinicopathologic features exhibited this small series are described to call attention early diagnosis treatment lymphoma. All...

Abstract Objectives Hepcidin plays a regulatory role in systemic iron homeostasis. GDF ‐15 has been found to be expressed from matured erythroblasts and very high levels of suppresses hepcidin secretion. In this study, we evaluated polycythemia vera ( PV ) essential thrombocythemia ET ). Methods The study included 29 patients 21 healthy controls. patient group 13 with 16 . Serum were measured at the time diagnosis, before initiation any therapy. Results did not differ significantly chronic...

Abstract Introduction Hodgkin lymphoma (HL) is unusual among malignancies, with inflammation playing such a prominent role in its pathogenesis. S100A8/A9 (calprotectin) heterodimeric protein, which has the inflammatory response and oncogenesis. In this study HL patients, correlation between serum levels treatment responses was investigated along whether marker correlated other markers. Materials Methods Thirty‐three patients 20 healthy volunteers were included. Demographic clinical...

GDF15, hepcidin and mitoferrin-1 (mfrn-1) are proteins involved in systemic iron regulation. There no studies the literature demonstrating serum mfrn-1 levels polycythemia vera (PV) essential thrombocythemia (ET) patients. The aim of this study was to investigate PV ET patients.Materials methods: Ten PV, 17 patients, 27 healthy controls (HCs) were enrolled. values measured with enzyme-linked immunosorbent assay (ELISA).Results: GDF15 higher myeloproliferative neoplasm (MPN) group (P =...

Background: Tumor lysis syndrome (TLS) is a potentially fatal complication of cancer therapy characterized by severe electrolyte and metabolic abnormalities such as hyperphosphatemia, hyperkalemia, hypocalcaemia. TLS usually occurs in aggressive hematologic malignancies Burkitt lymphoma acute leukemia. has rarely been observed multiple myeloma (MM). Case report: We present 2 patients with relapsed MM who developed after the first cycle carfilzomib treatment. Conclusion: Carfilzomib...

Anticonvulsant hypersensitivity syndrome is a fatal, idiosyncratic drug reaction that caused by aromatic antiepileptic drugs. This cutaneous also called pseudolymphoma because of its clinical and histological similarities with malignant lymphoma. The primary findings are fever, skin rashes, enlarged lymph nodes, single or multiple internal organ involvement hematological abnormalities. Typically, anticonvulsant occurs 1-8 weeks after administration. We herein present the case patient who had...

Calprotectin (CLP), S100A6, and high mobility group nucleosome-binding protein 1 (HMGN1), known as alarmins, are involved in the pathogenesis of many tumors. In this study, we aimed to investigate relationships serum CLP, HMGN1 levels with clinical laboratory findings patients multiple myeloma (MM) their roles MM.
