The effect of cryopreservation on engraftment kinetics in fully matched allogeneic stem cell transplantation: Real-life data and literature review.

Introduction: The standard approach for allogeneic stem cell transplantation (allo-SCT) is to administer donor cells on the same day as a fresh product to a patient who has been given a preparative regimen. The difficulty in collecting and transporting donor cells, especially during the COVID-19 pandemic, has made it essential to collect and cryopreserve the grafts before the recipient begins the transplant preparation regimen. However, the short- and long-term impacts of cryopreservation on transplant outcomes remain controversial.

Systemic inflammatory indices for predicting prognosis of myelofibrosis.

The impact of inflammatory markers such as systemic immune-inflammation (SII) index and systemic inflammation response index (SIRI) on myelofibrosis (MF) prognosis was evaluated for the first time in this study. Data from 60 patients diagnosed with MF between March 2011 and September 2022 were retrospectively analyzed. In addition to disease-related markers, the impact of SII and SIRI on prognosis was evaluated.

Potential modifications of the PLASMIC scoring system for predicting thrombotic thrombocytopenic purpura: Sometimes, less is more.

Introduction: Thrombotic thrombocytopenic purpura (TTP) is a life-threatening occlusive disease of the microcirculation characterized by systemic platelet plugs, organ ischemia, deep thrombocytopenia, and fragmentation of erythrocytes. One of the widely used scoring system to determine the clinical probability of TTP is the PLASMIC scoring system. This study aimed to evaluate the contribution of PLASMIC score modifications to sensitivity and specificity in patients with microangiopathic hemolytic anemia (MAHA) undergoing plasma exchange with a prediagnosis of TTP at our center.

The effect of the time from diagnosis to induction therapy on prognosis in patients with acute leukemia undergoing leukapheresis for symptomatic hyperleukocytosis.

Introduction: Our study investigated leukapheresis's effect on delayed induction therapy outcomes in patients with acute leukemia presenting with symptomatic hyperleukocytosis.

Methods: This retrospective cohort study included 30 adult patients diagnosed with acute leukemia who underwent leukapheresis for leukostasis. The patients were divided into the first 24 h and >24 h groups, according to the time from diagnosis to induction therapy (TDT).

Two Cases of Kidney Transplant Recipients With Multiple Relapsing Pure Red Cell Aplasia Due to Parvovirus B19 Infection.

Although anemia is common after kidney transplant, pure erythroid aplasia due to parvovirus B19 infection is rare. Therefore, there are delays in diagnosis in transplant patients. Here, we aimed to raise awareness that pure red blood cell aplasia due to parvovirus B19 should be considered in the differential diagnosis of posttransplant anemia.

Therapeutic plasma exchange in gastric signet ring cell carcinoma presenting as microangiopathic hemolytic anemia: A rare case report.

Microangiopathic hemolytic anemia (MAHA) defines a group of disorders characterized by the formation of microthrombi in capillaries and arterioles and the fragmentation of erythrocytes that pass through. Cancer-related MAHA is a rare but serious condition that is encountered in patients diagnosed with a malignancy. This clinical picture is thought to be linked to certain tumor characteristics; particularly, adenocarcinoma histology, vascular invasion, and bone marrow infiltration.

The Role of White Blood Cell Count in Perianal Pathologies: A Retrospective Analysis of Hematologic Malignancies.

Background And Objective: Infections are the most common cause of anal and perianal pathologies in patients with hematological malignancies. Perianal infection diagnosis in this group of patients is difficult; thus, a careful anorectal examination is necessary with imaging modalities. In addition, the literature reveals a knowledge gap in the approach to anal pathologies in patients with neutropenia during diagnosis or chemotherapy.

Is split-dose better than single-dose? Results of Turkish Stem Cell Coordination Center (TURKOK) donors in the era of rising biosimilar G-CSF.

Background: Turkish Stem Cell Coordination Center (TURKOK) carries out the procurement process of unrelated allogeneic hematopoietic stem cells in Turkey. This study aims to compare the efficacy of both once-daily and divided-dose G-CSF administration and the original and biosimilar G-CSF use and the frequency and severity of adverse events in TURKOK donors.

Method: The study was conducted retrospectively with 142 healthy TURKOK donors.

Castleman Disease: A Multicenter Case Series from Turkey.

Objective: Castleman disease (CD) is a rare disease also known as angiofollicular lymph node hyperplasia. The two main histological subtypes are the hyaline vascular and plasma cell variants. It is further classified as unicentric CD (UCD) or multicentric CD (MCD) according to the anatomical distribution of the disease and the number of lymph nodes involved.

Development of Agranulocytosis after Discontinuation of Methimazole: An Unusual Case.

Agranulocytosis is a rare and critical adverse effect of antithyroid drugs (ATD). The occurrence of agranulocytosis in continuous ATD treatment patients is well known; however, a case of ATD agranulocytosis occurring following the discontinuation of methimazole (MMI) treatment is not a usual situation. We herein describe a case of a 41-year-old woman who was previously administered methimazole (MMI) for ten days and developed ATD-induced agranulocytosis and symptoms of an upper respiratory tract infection after three weeks following discontinuation of MMI treatment.
