Method: All the patients with AL diagnosis being followed-up in the hematology department were recruited in the study. Clinicopathologic data were obtained. Factors related with overall survival (OS) including systemic inflammatory response markers were analyzed. Results: In 16 AL patients, the estimated OS was 58.6 +/- 10.8 months, with a-5-year- survival rate of 52.1%. While, 43.8% of the patients died during the study period. Gastrointestinal and respiratory complaints were the most frequent symptoms. Myocardial and renal biopsies were amyloid positive in 31.3% and 25% of the patients respectively. Myeloma was diagnosed in 18.8% and amyloid was positive in 31.3% of the bone marrow biopsies. There was no difference between surviving and deceased patients with respect to laboratory findings including systemic inflammatory markers. Only immunoglobulin M was significantly lower in the deceased patients and IgM was found to be the only factor independently associated with OS. Lower IgM levels were associated with decreased OS. An IgM value of 75.4 mg/dL was found as a cut-off value with a sensitivity and specificity of 71.4% and 66.7% respectively for the prediction of survival status. Conclusion: AL is a rare, progressive, systemic disease with a wide spectrum of clinical presentations. The disease most commonly presents with gastrointestinal and respiratory complaints. IgM level seems to be an independent predictor of survival and may be used as a prognostic marker.Item Secondary erythrocytosis due to waterpipe smoking: A case report(2015) Asma, Suheyl; Gereklioglu, Cigdem; Korur, Asli; Solmaz, SonerIn recent years, waterpipe smoking has gradually increased in our country, as in the world. Waterpipe smoking is a severe public health problem as cigarette smoking. Although the toxic substances are considered to be softened through passing from water, there is exposure to toxic substances and risk for contamination with some type of severe diseases. In addition, erythropoiesis is known to be induced with increased carboxy hemoglobin amount in blood and related secondary erythrocytosis may develop. Smoking-related tissue hypoxia is among the most common causes of secondary erythrocytosis. Herein, we presented a case that was admitted to family medicine clinic with various symptoms and diagnosed with narghile-related secondary erythocytosis.Item A Rare Complication Developing After Hematopoietic Stem Cell Transplantation: Wernicke's Encephalopathy(2015) Solmaz, Soner; Gereklioglu, Cigdem; Tan, Meliha; Demir, Senay; Yeral, Mahmut; Korur, Asli; Boga, Can; Ozdogu, Hakan; 25912759Thiamine is a water-soluble vitamin. Thiamine deficiency can present as a central nervous system disorder known as Wernicke's encephalopathy, which classically manifests as confusion, ataxia, and ophthalmoplegia. Wernicke's encephalopathy has rarely been reported following hematopoietic stem cell transplantation. Herein, we report Wernicke's encephalopathy in a patient with acute myeloid leukemia who had been receiving prolonged total parenteral nutrition after haploidentical allogeneic hematopoietic stem cell transplantation. To the best of our knowledge, this is the first case reported from Turkey in the literature.Item Red blood cell alloimmunization in patients with sickle cell disease in Turkey: a single center retrospective cohort study(2016) Solmaz, Soner; Karacaoglu, Pelin; Gereklioglu, Cigdem; Asma, Suheyl; Korur, Asli; Buyukkurt, Nurhilal; Kasar, Mutlu; Yeral, Mahmut; Kozanoglu, Ilknur; Boga, Can; Ozdogu, Hakan; 0000-0002-5086-5593; 0000-0002-8902-1283; 0000-0003-3856-7005; 0000-0002-0895-4787; 0000-0002-5268-1210; 0000-0002-9680-1958; AAD-5616-2021; AAD-5542-2021; AAL-3906-2021; AAE-1457-2021; ABC-4148-2020; AAD-6222-2021; AAE-1241-2021Purpose: We aimed to investigate erythrocyte alloimmunization frequency and related factors in our region where SCD is common Material and Methods: This study was planned as a single center, cross-sectional and retrospective cohort study. A total of 216 patients who had been followed up due to SCD [Hemoglobin (Hb) SS, Hb S-beta thalassemia, Hb S-alpha thalassemia] were included in this study. Patients were divided to two groups according to amount of transfusion. The patients who had received less than 6 transfusions per year and who did not have the history of erythropheresis were allocated to Group 1, and the patients who had received 6 or more simple transfusion per year or who had undergone erythrocyte exchange were allocated to Group 2 Results: Of 216 SCD patients included in the study. Alloimmunization was detected in 67 (31.0%) out of 216 patients who underwent transfusion, and in 17 (30.4%) out of 56 patients in Group 1 and in 50 (31.3%) out of 160 patients in Group 2. When the patients were analyzed according to alloimmunization development, our study revealed that neither SCD complications are a risk factor for alloimmunization nor alloimmunization increases mortality rates Conclusion: High alloimmunization frequency found in our study suggests the insufficient adherence of alloimmunization-prevention policies in RBC transfusions performed except experienced institutions. Therefore alloimmunization may be reduced or prevented through performing extended red cell typing among SCD patientsItem Is the Game Over or Starting Again? The Role of the Transplant Team in Genetic Counseling for Adult Sickle Cell Disease Recipients(2017) Aytan, Pelin; Gereklioglu, Cigdem; Yeral, Mahmut; Korur, Asli; Asma, Suheyl; Kozanoglu, Ilknur; Ozdogu, Hakan; Boga, Can; 0000-0002-5086-5593; 0000-0002-5268-1210; 0000-0001-5335-7976; 0000-0002-8902-1283; 0000-0002-2553-7715; 0000-0002-9680-1958; 0000-0002-9580-628X; 27956368; AAD-5616-2021; AAE-1241-2021; AAL-6544-2020; ABC-4148-2020; AAI-7831-2021; AAD-5542-2021; AAE-3833-2019; AAD-6222-2021Item Association between leptin and weight gain in patients receiving iron treatment(2018) Gereklioglu, Cigdem; Solmaz, Soner; Acibucu, Fettah; Sancakdar, Enver; Korur, Asli; Acibucu, Duygu Oguz; AAL-6544-2020Purpose: The aim of this study was to evaluate the relationship between leptin and weight gain in patients receiving iron treatment. Materials and Methods: A total of 42 female patients who were diagnosed with IDA were included in the study. Whole blood count, serum iron, serum unsaturated iron binding capacity (UIBC), serum ferritin level were measured at the time of diagnosis and on month one after treatment; serum hepcidin level and serum leptin level were measured at the time of diagnosis and 96 hours after commencement of parenteral therapy; body weight and appetite alterations were recorded at the time of diagnosis and on month one. Results: A statistically significant difference was not found between hepcidin and leptin values at the time of diagnosis and after treatment. Increased appetite was detected in 22 (52.4%) patients on month one after treatment. While mean weight of all patients was 69.6 +/- 17.9 kg at the time of diagnosis, it was 70.7 +/- 17.5 kg on month one after treatment and there was a statistically significant difference between two values. Conclusion: Our study revealed that appetite and body weight increased following iron therapy, consistently with our observations and hypothesis. However no significant relationship was found with leptin levels and weight increase.
