Item Comparison of the clinical course of COVID-19 infection in sickle cell disease patients with healthcare professionals(2021) Boga, Can; Asma, Suheyl; Leblebisatan, Goksel; Sen, Nazan; Tombak, Anil; Demiroglu, Yusuf Ziya; Yeral, Mahmut; Akin, Sule; Yesilagac, Hasan; Habesoglu, Mehmet Ali; Aribogan, Anis; Kasar, Mutlu; Korur, Asli; Ozdogu, Hakan; 0000-0002-9866-2197; 34032899; AAZ-9711-2021; AAY-2668-2021It is highly expected that COVID-19 infection will have devastating consequences in sickle cell disease (SCD) patients due to endothelial activation and decreased tissue and organ reserve as a result of microvascular ischemia and continuous inflammation. In this study, we aimed to compare the clinical course of COVID-19 in adult SCD patients under the organ injury mitigation and clinical care improvement program (BASCARE) with healthcare professionals without significant comorbid conditions. The study was planned as a retrospective, multicenter and cross-sectional study. Thirty-nine SCD patients, ages 18 to 64 years, and 121 healthcare professionals, ages 21 to 53, were included in the study. The data were collected from the Electronic Health Recording System of PRANA, where SCD patients under the BASCARE program had been registered. The data of other patients were collected from the Electronic Hospital Data Recording System and patient files. In the SCD group, the crude incidence of COVID-19 was 9%, while in healthcare professionals at the same period was 23%. Among the symptoms, besides fever, loss of smell and taste were more prominent in the SCD group than in healthcare professionals. There was a significant difference between the two groups in terms of development of pneumonia, hospitalization, and need for intubation (43 vs 5%, P < 0.00001; 26 vs 7%, P = 0.002; and 10 vs 1%, P = 0.002, respectively). Prophylactic low molecular weight heparin and salicylate were used more in the SCD group than in healthcare professionals group (41 vs 9% and 28 vs 1%; P < 0.0001 for both). The 3-month mortality rate was demonstrated as 5% in the SCD group, while 0 in the healthcare professionals group. One patient in the SCD group became continously dependent on respiratory support. The cause of death was acute chest syndrome in the first case, hepatic necrosis and multi-organ failure in the second case. In conclusion, these observations supported the expectation that the course of COVID-19 in SCD patients will get worse. The BASCARE program applied in SCD patients could not change the poor outcome.Item Factors Associated With Overall Survival in Acute Myeloid Leukemia Patients Before and After Hematopoietic Stem Cell Transplant(2021) Aytan, Pelin; Yeral, Mahmut; Korur, Asli; Gereklioglu, Cigdem; Kasar, Mutlu; Buyukkurt, Nur Hilal; Asma, Suheyl; Kazanoglu, Ilknur; Ozdogdu, Hakan; Boga, Can; 0000-0002-5086-5593; 0000-0001-5335-7976; 0000-0002-5268-1210; 0000-0002-9580-628X; 31424361; AAD-5616-2021; AAI-7831-2021; AAE-1241-2021Objectives: Our aim was to identify factors associated with overall survival and the efficacy of postrelapse treatment protocols and to determine whether pretransplant consolidation therapy and minimal residual disease status pose a survival benefit. Materials and Methods: Patients with acute myeloid leukemia who underwent stem cell transplant between 2007 and 2018 were enrolled retrospectively. The effects of pretransplant cytogenetic and minimal residual disease status, pretransplant consolidation therapies, development of graft-versus-host disease, postrelapse treatment protocols, and type of conditioning regimens on overall survival were analyzed. Results: In 76 study patients, the cumulative overall 1- and 5-year relapse probabilities were 67.8% and 58.7%, respectively. Overall survival rates at 3 and 5 years in patients with and without relapse were 23.5% and 0% and 95.9% and 91.1% (P<.001), respectively. Although mean postrelapse overall survival was better with intensive salvage plus donor lymphocyte infusion, no significant differences were shown versus other therapies (intensive salvage, nonintensive salvage, intensive salvage or nonintensive salvage plus donor lymphocyte infusion, or supportive therapy). Twenty-three patients (30.3%) died during the study period with a median survival of 9.6 months. Patients with favorable, intermediate, and unfavorable cytogenetic status showed overall survival of 46.6 +/- 10.4, 54.6 +/- 4.4, and 36.9 +/- 5.9 months (P=.807). Patients with and without minimal residual disease and patients who received or did not receive consolidation therapy had similar overall survival. Relapse was an independent predictor of overall survival (increased mortality risk of 26.22). Patients who developed graft-versus-host disease showed decreased relapse. Conclusions: Relapse is the most important predictor of overall survival and is associated with poor prognosis. Pretransplant minimal residual status and cytogenetic status showed no effect on relapse rates and overall survival, and consolidation therapy did not improve outcomes.Item The Impact of the Ferric Carboxymaltose on Hemoglobin and Ferritin Levels(2020) Korur, Asli; Gereklioglu, Cigdem; Asma, Suheyl; Aytan, Pelin; Tanrikulu, Funda P.; Solmaz, Soner; Kasar, Mutlu; Buyukkurt, Nurhilal; Yeral, Mahmut; Boga, Can; Ozdogu, Hakan; 0000-0003-3856-7005; 0000-0002-8902-1283; 0000-0002-5086-5593; 0000-0002-0895-4787; 0000-0001-5335-7976; 0000-0002-9580-628X; 0000-0002-9680-1958; 32776750; AAD-6222-2021; AAL-3906-2021; AAD-5542-2021; AAD-5616-2021; AAE-1457-2021; ABC-4148-2020; AAI-7831-2021Background: Anemia is a frequent disorder worldwide. Iron deficiency anemia (IDA) is the most common form of anemia. Although oral iron is the first choice for treatment, the efficacy of oral iron preparations may be limited. Ferric carboxymaltose (FCM) is a novel parenteral iron preparation which can rapidly replenish iron stores. The aim of the present study is to investigate the impact of FCM dose on hemoglobin (Hb) and ferritin levels and the frequency of hypersensitivity reactions. Methods: This study was conducted with 765 IDA patients between September 1, 2016 and September 1, 2018. Hemoglobin (Hb), serum ferritin, transferrin saturation values were examined at the time of diagnosis, Hb and ferritin values at first month. Results: Post-treatment Hb and ferritin levels significantly increased. The mean Hb level alteration was 2.43 +/- 1.2 g/dL, the median ferritin level alteration was 157.3 ng/mL. The mean Hb level was lower and the mean change in Hb level was higher in higher doses. Allergic reactions were more frequent in higher doses. Conclusions: Ferric carboxymaltose is a novel treatment option with a low risk of hypersensitivity reactions and well tolerated even in high doses.Item Anorectal Complications During Neutropenic Period in Patients with Hematologic Diseases(2016) Solmaz, Soner; Korur, Asli; Gereklioglu, Cigdem; Asma, Suheyl; Buyukkurt, Nurhilal; Kasar, Mutlu; Yeral, Mahmut; Kozanoglu, Ilknur; Boga, Can; Ozdogu, Hakan; 26977278Background: Neutropenic patients are susceptible to any anorectal disease, and symptomatic anorectal disease afflicts 2-32% of oncology patients. Perianal infections are the most feared complication, considering the lack of natural defense against infectious microorganisms. When septic complications develop, the anorectal disease is potentially fatal, especially in neutropenic patients in whom mortality rates range between 11-57%. Although anorectal diseases are a frequent complication with potentially fatal outcomes among patients with hematologic diseases, sufficient data are not available in the literature. In this study, we aimed to investigate the anorectal complications developing during the neutropenic period in patients with hematologic diseases. Methods: A total of 79 patients whose neutropenic period (absolute neutrophil count < 500/mcL) continued for 7 days, or longer were included in the study. Results: A total of 34 patients out of 79 (43%) were detected to develop anorectal complications, of them 6 (7.6%) developed an anorectal infection. The patients were characterized according to the hematological disease and its status (active or not), the type of treatment and the presence of a history of an anorectal pathology before the onset of the hematologic disease. Nineteen (24.1%) patients had the history of anorectal disturbances before diagnosis of the hematologic disease, and recurrence of an anorectal pathology was found in 14 out of 19 patients(73.7%). In addition, the overall mortality rate was higher among the patients who developed anorectal complications compared to another group (41.2% vs. 22.2%, p= 0.059). Conclusion: Anorectal pathology is a common complication with high recurrence rate in neutropenic patients. Perianal infections are important as they can cause life-threatening outcomes although they are relatively rare among all anorectal complications. Therefore perianal signs and symptoms should be meticulously evaluated concerning early diagnosis and treatment.Item Organ damage mitigation with the Baskent Sickle Cell Medical Care Development Program (BASCARE)(2018) Boga, Can; Ozdogdu, Hakan; Asma, Suheyl; Kozanoglu, Ilknur; Gereklioglu, Cigdem; Yeral, Mahmut; Buyukkurt, Nurhilal Turgut; Solmaz, Soner; Korur, Asli; Aytan, Pelin; Maytalman, Erkan; Kasar, Mutlu; 0000-0002-5086-5593; 0000-0002-0895-4787; 0000-0002-8902-1283; 0000-0003-3856-7005; 0000-0001-5335-7976; 0000-0002-5268-1210; 0000-0002-2553-7715; 0000-0001-5284-7439; 0000-0002-9680-1958; 0000-0002-9580-628X; 29419693; AAD-5616-2021; AAE-1457-2021; AAL-6544-2020; AAD-6222-2021; AAD-5542-2021; AAL-3906-2021; AAI-7831-2021; AAE-1241-2021; AAE-3833-2019; ABC-4148-2020; F-6265-2019The Eastern Mediterranean is among the regions where sickle cell disease (SCD) is common. The morbidity and mortality of this disease can be postponed to adulthood through therapies implemented in childhood. The present study focuses on the organ damage-reducing effects of the Baskent Sickle Cell Medical Care Development Program (BASCARE), which was developed by a team who lives in this region and has approximately 25 years of experience. The deliverables of the program included the development of an electronic health recording system (PRANA) and electronic vaccination system; the use of low citrate infusion in routine prophylactic automatic erythrocyte exchange (ARCE) programs including pregnant women; the use of leukocyte-filtered and irradiated blood for transfusion; the use of magnetic resonance imaging methods (T2(*)) for the management of transfusion-related hemosiderosis; and the implementation of an allogeneic hematopoietic stem cell transplantation protocol for adult patients. The sample was composed of 376 study subjects and 249 control subjects. The hospital's Data Management System and the central population operating system were used for data collection. BASCARE enabled better analysis and interpretation of complication and mortality data. Vaccination rates against influenza and pneumococcal disease improved (21.5% vs 50.8% and 21.5% vs 49.2%, respectively). Effective and safe ARCE with low citrate infusion were maintained in 352 subjects (1003 procedures). Maternal and fetal mortality was prevented in 35 consecutive pregnant patients with ARCE. Chelating therapy rates reduced from 6.7% to 5%. Successful outcomes could be obtained in all 13 adult patients who underwent allogeneic peripheral stem cell transplantation from a fully matched, related donor. No patients died by day 100 or after the first year. Cure could be achieved without graft loss, grades III to IV acute graft versus host disease, extensive chronic graft versus host disease, or other major complications. The BASCARE program significantly improved patient care and thereby prolonged the life span of SCD patients (42 +/- 13 years vs 29 +/- 7 years, P < .001). We may recommend using such individualized programs in centers that provide health care for patients with SCD, in accordance with holistic approach due to the benign nature but malignant course of the disease.
