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,...

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...

<b><i>Background/Aims:</i></b> Multiple myeloma (MM) is a hematological cancer associated with increased clonal malignant plasma cells. Growth differentiation factor 15 (GDF 15) protein that highly expressed in the bone marrow mesenchymal stem cells of patients MM. This study investigated whether clinical stage disease, treatment response and survival are affected by pretreatment serum GDF levels. <b><i>Methods:</i></b> Serum levels were...

Background: IL-6, IL1-β, TNF-α and IL-21 have been identified in the growth, progression dissemination of multiple myeloma. To dte, there is no published data about serum levels patients with In present study we investigated circulating cytokines, such as IL-1β, TNF-α, association these disease stage newly diagnosed myeloma patients. Materials Methods: Twenty healthy controls 44 were evaluated. Patients classified according to Durie-Salmon criteria, international staging system (ISS) bone...

Littoral cell angioma (LCA) of the spleen is a relatively recently described rare entity, which associated with haemophagocytosis. In this case report, we will present myelodysplastic syndrome multiple LCA spleen. The patient presented pancytopenia and haemangiomas were observed in during diagnostic abdominal ultrasound. She required transfusion one to two units packed blood every 4-6 weeks she eventually underwent splenectomy order decrease requirement. Although patient's improved after...

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...

Immune thrombocytopenia (ITP) is an autoimmune disease characterized by peripheral thrombocyte destruction. In some disorders, heat-shock proteins (HSP) are suggested to be important antigenic factor. this study, we demonstrated the serum free levels of HSP60, HSP70, anti-HSP60, and anti-HSP70 in ITP patients healthy controls. Twenty-eight newly diagnosed patients, 35 chronic phase, 25 controls were enrolled study. Serum determined ELISA method. HSP60 significantly decreased when compared...
