Therapeutic plasma exchange (TPE) is an apheresis procedure in which plasma is separated from the blood cellular components ex vivo, allocated, and replaced with another plasma or a plasma-replacing fluid. This study aimed to define the rate of complications and determine TPE distribution in various neurological diseases. Our study is a retrospective analysis of neurologic diseases requiring TPE between 2008 and 2019 that were selected using the medical records of neurology departments and apheresis units database. We performed 1459 TPE procedures on 207 patients between 2008 and 2019. TPE Procedure is most frequently applied in patients with Myasthenia-Gravis syndrome (34.7%). The complication ratio was 1.6% from a total of 1459 TPE procedures. The most commonly specified adverse event was allergic reactions 11 (5.3%), followed by hypotension 6 (2.9%). TPE was safe and tolerable, with manageable complications in experienced hands.

Objective: Multiple myeloma (MM) is a malignant condition characterized by the accumulation of malignant plasma cells. Although MM remains incurable, the survival of MM patients has improved considerably due to the application of autologous stem cell transplantation, novel agents, and advanced treatment strategies. This study aimed to determine the cytogenetic characterization and bone marrow (BM) features of Turkish patients with MM. Materials and Methods: Eighty-five MM patients were admitted to Dokuz Eylül University Hospital in Turkey. BM samples of these MM patients were subjected to cytogenetic analyses at diagnosis and during therapy as a part of therapeutical and clinical evaluation. A complete cytogenetic study was performed using the G-banding technique. Fluorescence in situ hybridization (FISH) analysis was performed using cytoplasmic immunoglobulin. The degree of BM fibrosis was determined using reticulin histochemical staining. We determined the percentage of BM plasma cells based on the extent of CD38 staining. Results: Eighty-five MM patients were retrospectively identified between 2015 and 2021. The median age was 63 (38-90) years. Of the 85 patients, 60 (70.6%) were male and 25 (29.4%) were female. Seventy-two (84.7%) cases had BM fibrosis at the time of diagnosis. The most common was grade 2 fibrosis, recorded in 35 cases (41.2%). About 72.9% of the patients showed more than 50% plasma cells. FISH analysis indicated the presence of abnormal chromosomes in 37% (32/85) of the patients. The most frequent abnormality was Immunoglobulin heavy-chain (IGH) translocation (21.3%). Conclusion: Subgroup analysis of IGH mutations is crucial in the identification of high-risk MM patients. We believe that our study will contribute to the determination of BM biopsy and cytogenetic features of MM patients in our country.
Acute myeloid leukemia (AML) with myelodysplasia-related changes (AML-MRC) is a new disease category, which was defined as a separate entity in the World Health Organization Classification of Tumours of Haematopoietic and Lymphoid Tissues. While pre-treatment iron overload in patients with myelodysplastic syndrome has been previously studied, its relationship with AML-MRC has not been studied. We aimed to investigate the relationship between serum iron tests compatible with iron overload and the diagnosis of multilineage dysplasia (MLD) and AML with myelodysplasia-related changes (AML-MRC) in AML patients diagnosed at Hacettepe University Adult Hospital between January 2002 and September 2017. Ninety-three patients who met the criteria were enrolled. Bone marrow aspirate of each patient was reexamined , and dysplasia was investigated; other data were examined from patient's records. The iron overload status at diagnosis and transferrin saturation (TS) values were compared between the groups with and without MLD and those with and without AML-MRC. When iron overload was defined as TS ≥ 58% and ferritin ≥ 500 ng/mL, iron overload was observed in 10 (37%) patients with MLD and in 4 (13%) without MLD. The difference is almost statistically significant (p = 0.053). The mean TS value and frequency of iron overload were higher in AML-MRC patients than in non-AML-MRC patients (p < 0.05 for both). A mild positive significant correlation was observed between the dysplasia severity score and TS (r = 0.317, p = 0.032). In patients with AML-MLD and AML-MRC, iron overload occurred regardless of the transfusion status at the time of diagnosis. Morphologic severity of dysplasia may be correlated with higher TS values at the time of diagnosis.
Background:Background: Multiple myeloma (MM) is a clonal disease characterized by a neoplastic proliferation of plasma cells that make up approximately 10% of hematologic malignancies. Autologous hematopoietic stem cell transplantation (ASCT) after an induction regimen using combination of immunomodulatory drugs, proteasome inhibitors and dexamethasone is considered the standard treatment of newly diagnosed multiple myeloma in eligible patients.
