Öğe Acute Lymphoblastic Leukemia in Routine Practice: A Turkish Multicenter Study(Galenos Yayincilik, 2019) Ciftciler, Rafiye; Sevindik, Omur Gokmen; Tekgunduz, Ali Irfan Emre; Erkurt, Mehmet Ali; Vural, Filiz; Turgut, Burhan; Kaynar, LeylagulObjective: Significant developments occurred in the clinical management of acute lymphoblastic leukemia (ALL) in adults in recent decades. However, treatment results are still not satisfactory, especially in routine practice. The objective of this study was to evaluate the general clinical features, treatment details, and outcomes of a large group of patients followed in multiple centers in Turkey with a diagnosis of ALL. Materials and Methods: A retrospective analysis of the data of patients with ALL was made, the patients having been diagnosed and treated between January 2003 and June 2017 by different protocols in the hematology clinics of ten different centers. A total of 288 patients, aged between 17 and 76 years old, were included in the study. In this retrospective multicenter analysis of patients with ALL, classification of patients was performed based on treatment period, Philadelphia chromosome positivity, treatment regimen, and administration of allogeneic hematopoietic stem cell transplantation (allo-HSCT). Results: The majority of cases were B-cell in origin, while 224 patients had B-ALL and 64 of the patients had T-ALL. Median follow-up duration for all patients was 18.2 months (range: 0.03-161 months). Philadelphia chromosome positivity was determined in 49 patients (21.9%), and 54 patients (18.8%) were receiving allo-HSCT. After induction chemotherapy, 219 patients (76.0%) achieved complete remission, 32 patients (11.2%) were evaluated as treatment refractory, and 37 patients (12.8%) were deceased. Median overall survival was 47.7 months (95% confidence interval: 36.1-59.2) and median disease-free survival was 23.4 months (95% confidence interval: 6.7-40.0) for all patients. Conclusion: Multicenter studies are extremely important for defining the specific clinical features of a particular disease. The results of this study will make a significant contribution to the literature as they reflect real-life data providing valuable information about the Turkish ALL patient profile.Öğe Convalescent plasma therapy in patients with COVID-19(Pergamon-Elsevier Science Ltd, 2021) Altuntas, Fevzi; Yigenoglu, Tugce Nur; Bascl, Semih; Dal, Mehmet Sinan; Korkmaz, Serdal; Turgut, Burhan; Erkurt, Mehmet Ali[Abstract Not Available]Öğe International Forum: The Turkish perspective on apheresis activity: The Turkish apheresis registry report(Pergamon-Elsevier Science Ltd, 2023) Ozatli, Duzgun; Giden, Asli Odabasi; Erkurt, Mehmet Ali; Korkmaz, Serdal; Basci, Semih; Ulas, Turgay; Turgut, BurhanTherapeutic apheresis is an extracorporeal treatment that selectively removes abnormal cells or harmful sub-stances in the blood that are associated with or cause certain diseases. During the last decades the application of therapeutic apheresis has expanded to a broad spectrum of hematological and non-hematological diseases due to various studies on the clinical efficacy of this procedure. In this context there are more than 30 centers per-forming therapeutic apheresis and registered in the apheresis database in Turkey. Herein, we, The Turkish Apheresis Registry, aimed to analyze some key articles published so far from Turkey regarding the use of apheresis for various indications.Öğe Therapeutic plasma exchange in patients with neurologic diseases: Retrospective multicenter study(Pergamon-Elsevier Science Ltd, 2008) Kaynar, Leylagul; Altuntas, Fevzi; Aydogdu, Ismet; Turgut, Burhan; Kocyigit, Ismail; Hacioglu, Sibel Kabukcu; Ismailogullari, SevdaTherapeutic plasma exchange (TPE) is commonly used in many neurological disorders where an immune etiology was known or suspected. We report our experience with TPE performed for neuroimmunologic disorders at four university hospitals. The study was a retrospective review of the medical records of neurological patients (n = 57) consecutively treated with TPE between April 2006 and May 2007. TPE indications in neurological diseases included Guillain-Barre Syndrome (GBS) (n = 41), myasthenia gravis (MG) (n = 11), acute disseminated encephalomyelitis (ADEM) (n = 3), chronic inflammatory demyelinating polyneuropathy (CIDP) (n = 1) and multiple sclerosis (MS) (n 1). Patient median age was 49; there was a predominance of males. Twenty-two patients had a history of other therapy including intravenous immunoglobulin (IVIG), steroid, azothioprin, and pridostigmine prior to TPE. Another 35 patients had not received any treatment prior to TPE. All patients were classified according to the Hughes functional grading scores pre- and first day post-TPE for early clinical evaluation of patients. The TPE was carried out 1-1.5 times at the predicted plasma volume every other day. Two hundred and ninety-four procedures were performed on 57 patients. The median number of TPE sessions per patient was five, and the median processed plasma volume was 3075 mL for each cycle. Although the pre-TPE median Hughes score of all patients was 4, it had decreased to grade I after TPE. While the pre-TPE median Hughes score for GBS and MG patients was 4, post-TPE scores were decreased to grade 1. Additionally, there was a statistically significant difference between post-TPE Hughes score for GBS patients with TPE as front line therapy and patients receiving IVIG as front line therapy (1 vs. 3.5; p = 0.034). Although there was no post-TPE improvement in Hughes scores in patients with ADEM and CIDP, patients with MS had an improved Hughes score from 4 to 1. Mild and manageable complications such as hypotension and hypocalcemia were also observed. TPE may be preferable for controlling symptoms of neuroimmunological disorders in early stage of the disease, especially with GBS. (C) 2008 Elsevier Ltd.
