    Background and objectives: To consider the effectiveness of apheresis, which is a supportive treatment method, in sepsis. Materials and methods: A hundred and eleven adults with sepsis or septic shock were included in this retrospective study. The demographic characteristics of the patients, the focus and source of infection causing sepsis or septic shock, characteristics of the pathogen, Acute Physiological and Chronic Health Assessment (APACHE) II score, routine laboratory values, which apheresis method was used, the characteristics of the replacement fluids used during the apheresis procedure, the number of apheresis procedures, complications related to the apheresis procedure, the follow-up time after the procedure, and mortality were recorded. The primary outcome was 28day mortality. Results: Sixty-nine (62.2 %) of the patients were male. The mean age of the patients was 47.7 +/- 18.6 years. The most common source of sepsis was hospital-acquired (79.3 %), the most common pathogen causing sepsis was gram-negative bacteria (41.4 %), and the most common infection site was the respiratory tract (58.7 %). The median APACHE II score was 19 (13-24). 92 (82.9 %) of the patients had septic shock. Theropeutic plasma exchange (TPE) was performed in 11.7 % of the patients and immunoabsorbtion IA in 88.3 %. The median number of sessions was 3 (3-5). No procedure-related fatal complication was observed in the study. While 28day mortality was 61.3 % in all patients, when the mortality according to the apheresis procedures was examined, it was 11.3 % and 88.2 % in the patients who underwent TPE and IA, respectively. The most common cause of mortality was multiorgan failure. Conclusions: Apheresis in sepsis can be considered as a salvage treatment. The indication for apheresis in sepsis is still at the level of patient-based individualized decision in line with the studies done so far, including our study. However, there is a need for a multicenter randomized controlled study with a large number of patients in order to give positive or negative recommendations about its effectiveness.

    Clinical characteristics and therapeutic outcomes of elderly patients with chronic myeloid leukemia: A retrospective multicenter study
    (Wiley, 2015) Korkmaz, Serdal; Dal, Mehmet Sinan; Berber, Ilhami; Sahin, Deniz Goren; Dogu, Mehmet Hilmi; Ayyildiz, Orhan; Nizam, Ilknur
    AimsWe aimed to investigate whether older age leads to limitations in the starting dose of imatinib in daily treatment of chronic myeloid leukemia, and to determine the compliance of elderly patients with tyrosine kinase inhibitors (TKI) therapy. MethodsData including the clinical characteristics, therapeutic outcomes and compliance with TKI therapy of elderly patients with chronic myeloid leukemia aged >65years were collected from 13 institutions in Turkey, retrospectively. ResultsA total of 69 patients (27 [39%] men, 42 [61%] women) were evaluated retrospectively. The median age of the patients was 71years (range 66-85years). Of the patients, 66 (96%) were in the chronic phase and three (4.3%) were in the accelerated phase when diagnosed. A total of 63 (91.3%) patients were receiving imatinib as the first-line therapy. The initial dose of imatinib was 400mg/day in 59 patients (93.6%). Imatinib treatment induced 57 (90.5%) complete hematological responses at 3months, 29 (46%) complete cytogenetic responses at 6months and 49 (77.7%) major molecular responses at 12months. As a result, nilotinib and dasatinib were used in 14 patients as second-line therapy. Second-line TKI induced nine complete hematological responses (64.3%) at 3months, four complete cytogenetic responses (28.6%) at 12months and seven major molecular responses (50%) at 18months. A total of 56 of the patients (81.2%) are still alive. The median overall survival and progression-free survival rates were 35months (range 1-95months) and 17months (range 0.8-95months), respectively. ConclusionElderly patients should receive TKI according to the same guidelines that apply to younger patients. Geriatr Gerontol Int 2015; 15: 729-735.

    A multicenter retrospective analysis on therapeutic plasma exchange in immune thrombocytopenic purpura
    (Pergamon-Elsevier Science Ltd, 2021) Basturk, Abdulkadir; Sayin, Serhat; Erkurt, Mehmet Ali; Sarici, Ahmet; Ekinci, Omer; Kum, Asli; Berber, Ilhami
    Immune Thrombocytopenia (ITP) is an autoimmune disease characterized by thrombocytopenia and skin and mucosal bleeding. In patients with an indication for treatment, corticosteroids, intravenous immunoglobulin (IVIg) and anti-D are recommended as the first line, while splenectomy, thrombopoietin receptor agonists or rituximab are recommended second line options. Approximately 10 % of adult patients with ITP fall into the chronic refractory ITP group. Therapeutic plasma exchange (TPE) has generally been tested in patients with refractory ITP, who have failed to respond to conventional treatments, in case of bleeding or prior to surgical interventions. It has been stated that elimination of the antibodies that are held responsible in the pathogenesis of the disease has an effective role in the treatment. In this article, we present the results of 17 patients, who underwent TPE for refractory ITP, together with the literature data.
