Background: 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.

(2023) Boga, Can; Sisli, Selen Nihal; Bahar, Abdul Rasheed; Tamer, Yusuf; Kasar, Mutlu; Bascil, Sibel; Ozdogu, Hakan; Asma, Suheyl; Demiroglu, Yusuf Ziya; Yeral, Mahmut; 0000-0002-0225-2477; 37341460; ADG-7352-2022
Objectives: It is unclear whether patients with oral foci of infection should be approved for hematopoietic stem cell transplant with or without posttransplant cyclophosphamide. We compared the presence of oral foci of infection status on the effects of various conditioning regimens for such patients.Materials and Methods: Three groups were classified as autologous (carmustine-etoposide-cytarabinemelphalan, mitoxantrone-melphalan, and melphalan 200 mg/m2 groups; n = 502 patients), and 6 groups were classified as allogeneic (busulfan-fludarabinerabbit anti-T-lymphocyte globulin, busulfanfludarabine-posttransplant cyclophosphamide, fludarabine-cyclophosphamide-anti-T-lymphocyte globulin, busulfan-fludarabine-anti-T-lymphocyte globulin-posttransplant cyclophosphamide, total body irradiation-posttransplant cyclophosphamide, and other; n = 428 patients). Data were collected from a database that met international accreditation requirements. We evaluated dental radiological findings and calculated interobserver reliability.Results: Oral foci of infections increased febrile neutropenia and bacterial infection frequencies in both groups but only increased mucositis frequency in patients with allogeneic treatment. The frequencies of oral foci of infection-related complications were similar in both the autologous and allogeneic groups. Rate of graft-versus-host disease was not affected by oral foci of infection status. Periodontitis/cysts and periapical lesions increased the risk of infections at day 100 in the mitoxantrone-melphalan group versus the melphalan 200 mg/m2 group. We observed no differences among the autologous transplant groups in terms of early mortality. Similarly, no differences in early mortality were observed among the allogeneic groups.Conclusions: Transplant is a valid option in patients with oral foci of infections undergoing various autologous and allogeneic transplant protocols when time is of the essence, even at myeloablative dose intensities.

(2014) Kasar, Mutlu; Boga, Can; Yeral, Mahmut; Asma, Suheyl; Kozanoglu, Ilknur; Ozdogu, Hakan; https://orcid.org/0000-0003-3856-7005; https://orcid.org/0000-0002-9680-1958; https://orcid.org/0000-0002-9580-628X; https://orcid.org/0000-0001-5335-7976; https://orcid.org/0000-0002-5268-1210; https://orcid.org/0000-0002-8902-1283; 24254379; AAL-3906-2021; AAD-6222-2021; ABC-4148-2020; AAI-7831-2021; AAE-1241-2021; AAD-5542-2021
Increased thrombocyte activation leads to a higher likelihood of coagulation in sickle-cell disease. On the other hand, chronic inflammation and endothelial cell activation promote vaso-occlusion. The effect of circulating microparticles derived from erythrocytes, monocytes, thrombocytes, and endothelial cells on the vaso-occlusive process is unclear. This study aims to analyze the relationship between sickle-cell disease and miscellaneous organ complications by defining the circulating microparticles during the steady-state and painful crisis periods in 45 patients with sickle-cell disease. Microparticle analysis was conducted using an eight-parameter flow cytometric method, using CD61 PERCP, CD142PE, CD106 FITC, CD14 APC-H7, CD235a FITC, and Annexin-V APC monoclonal antibodies. Microparticle levels of sickle-cell patients were found to be significantly higher during both painful crisis and steady-state situations compared with the control group (for all, p < 0.001). Among these microparticles, levels of erythrocyte microparticles (eMPs) were significantly higher during crisis than in the steady-state period (eMP steady state vs. painful crisis: 7.59 +/- 12.24 vs. 7.59 +/- 12.24, respectively; p < 0.01). Microparticles, including eMPs, were not affected by hydroxyurea treatment. Their level did not reflect the high frequency of crisis (>3 times/year). Thrombocyte microparticle levels were found to be higher in patients with nephropathia than in those without ( 48.05 +/- 40.23 vs. 7.67 +/- 6.75, respectively; p < 0.049). Circulating microparticles seem to be involved in the pathogenesis of sickle-cell disease. eMPs may help with the management of crisis. Thrombocyte microparticles might predict renal damage induced by vaso-occlusion.
The Clinicopathologic Features and the Factors Associated with the Survival in Light -Chain Amyloidosis Patients: A Single Center Descriptive Study
(2020) Aytan, Pelin; Yeral, Mahmut; Gereklioglu, Cigdem; Kasar, Mutlu; Korur, Asli; Buyukkurt, Nurhilal; Asma, Suheyl; Kozanoglu, Ilknur; Ozdogu, Hakan; Boga, Can; 0000-0002-5086-5593; 0000-0003-3856-7005; 0000-0002-0895-4787; 0000-0002-8902-1283; 0000-0002-5268-1210; 0000-0002-9680-1958; AAD-6222-2021; AAD-5616-2021; AAL-3906-2021; AAE-1457-2021; AAD-5542-2021; AAE-1241-2021
Objective: To present the clinicopathologic features and assess the factors related to the survival in light- chain amyloidosis (AL) patients. 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.

(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-2668-2021
It 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.

Sickle cell disease (SCD), one of the most common genetic disorders worldwide, is characterized by hemolytic anemia and tissue damage from the rigid red blood cells. Although hydroxyurea and transfusion therapy are administered to treat the accompanying tissue injury, whether either one prolongs the lifespan of patients with SCD is unknown. SCD-related mortality data are available, but there are few studies on mortality-related factors based on evaluations of surviving patients. In addition, ethnic variability in patient registries has complicated detailed analyses. The aim of this study was to investigate mortality and mortality-related factors among an ethnically homogeneous population of patients with SCD. The 735 patients (102 children and 633 adults) included in this retrospective cohort study were of Eti-Turk origin and selected from 1367 patients seen at 5 regional hospitals. A central population management system was used to control for records of patient mortality. Data reliability was checked by a data supervision group. Mortality-related factors and predictors were identified in univariate and multivariate analyses using a Cox regression model with stepwise forward selection. The study group included patients with homozygous hemoglobin S (Hgb S) disease (67 %), Hb S-beta(0) thalassemia (17 %), Hgb S-beta(+) thalassemia (15 %), and Hb S-alpha thalassemia (1 %). They were followed for a median of 66 +/- 44 (3-148) months. Overall mortality at 5 years was 6.1 %. Of the 45 patients who died, 44 (6 %) were adults and 1 (0.1 %) was a child. The mean age at death was 34.1 +/- 10 (18-54) years for males, 40.1 +/- 15 (17-64) years for females, and 36.6 +/- 13 (17-64) years overall. Hydroxyurea was found to have a notable positive effect on mortality (p = 0.009). Mortality was also significantly related to hypertension and renal damage in a univariate analysis (p = 0.015 and p = 0.000, respectively). Acute chest syndrome, splenic sequestration, and prolonged painful-crisis-related multiorgan failure were the most common causes of mortality. In a multivariate analysis of laboratory values, only an elevated white blood cell count was related to mortality (p = 0.009). These data show that despite recent progress in the treatment of SCD, disease-related factors continue to result in mortality in young adult patients. Our results highlight the importance of evaluating curative treatment options for patients who have an appropriate stem cell donor in addition to improving patient care and patient education.

Objective: Obtaining informed consent from hematopoietic stem cell recipients and donors is a critical step in the transplantation process. Anxiety may affect their understanding of the provided information. However, use of audiovisual methods may facilitate understanding. In this prospective randomized study, we investigated the effectiveness of using an audiovisual method of providing information to patients and donors in combination with the standard model. Materials and Methods: A 10-min informational animation was prepared for this purpose. In total, 82 participants were randomly assigned to two groups: group 1 received the additional audiovisual information and group 2 received standard information. A 20-item questionnaire was administered to participants at the end of the informational session. Results: A reliability test and factor analysis showed that the questionnaire was reliable and valid. For all participants, the mean overall satisfaction score was 184.8 +/- 19.8 (maximum possible score of 200). However, for satisfaction with information about written informed consent, group 1 scored significantly higher than group 2 (p=0.039). Satisfaction level was not affected by age, education level, or differences between the physicians conducting the informative session. Conclusion: This study shows that using audiovisual tools may contribute to a better understanding of the informed consent procedure and potential risks of stem cell transplantation.

(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-1241-2021
Objectives: 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.
Factors effecting influenza vaccination uptake among health care workers: a multi-center cross-sectional study
(2016) Asma, Suheyl; Akan, Hulya; Uysal, Yucel; Pocan, A.Gurban; Sucakli, Mustafa Haki; Yengil, Erhan; Gereklioglu, Cigdem; Korur, Asli; Bashan, Ibrahim; Erdogan, A.Ferit; Ozsahin, A.Kursat; Kut, Altug; 27142774
Background: The present study aimed to identify factors affecting vaccination against influenza among health professionals. Methods: We used a multi-centre cross-sectional design to conduct an online self-administered questionnaire with physicians and nurses at state and foundation university hospitals in the south-east of Turkey, between 1 January 2015 and 1 February 2015. The five participating hospitals provided staff email address lists filtered for physicians and nurses. The questionnaire comprised multiple choice questions covering demographic data, knowledge sources, and Likert-type items on factors affecting vaccination against influenza. The target response rate was 20 %. Results: In total, 642 (22 %) of 2870 health professionals (1220 physicians and 1650 nurses) responded to the questionnaire. Participants' mean age was 29.6 +/- 9.2 years (range 17-62 years); 177 (28.2 %) were physicians and 448 (71.3 %) were nurses. The rate of regular vaccination was 9.2 % (15.2 % for physicians and 8.2 % for nurses). Increasing age, longer work duration in health services, being male, being a physician, working in an internal medicine department, having a chronic disease, and living with a person over 65 years old significantly increased vaccination compliance (p < 0.05). We found differences between vaccine compliant and non-compliant groups for expected benefit from vaccination, social influences, and personal efficacy (p < 0.05). Univariate analysis showed differences between the groups in perceptions of personal risks, side effects, and efficacy of the vaccine (p < 0.05). Multivariate analysis found that important factors influencing vaccination behavior were work place, colleagues' opinions, having a chronic disease, belief that vaccination was effective, and belief that flu can be prevented by natural ways. Conclusion: Numerous factors influence health professionals' decisions about influenza vaccination. Strategies to increase the ratio of vaccination among physicians and nurses should consider all of these factors to increase the likelihood of success.

Objectives: Allogeneic hematopoietic stem cell transplant is a curative treatment option for many hematologic diseases. The existence of a fully compatible donor for recipients is the first condition for minimized transplant-related mortality and morbidity. The best donor for hematopoietic stem cell transplant is an HLA-matched sibling donor. The possibility of finding an HLA-matched sibling is less than 30% worldwide. Hematopoietic stem cell transplant is needed for an increasing number of patients every year, but the ability to find a fully compatible donor has limited its use. Materials and Methods: From August 2012 to May 2017, we screened 412 adult patients who required AHSCT and their families for HLA tissue groups who were seen at our center (Baskent University Adana Dr. Turgut Noyan Research and Medical Center Hematology Unit). To screen tissue groups at our center, we perform lowresolution typing for HLA-A, B, -C, -DRB1, and -DQB. If an HLA genotype cannot be identified, verification typing is done using high-resolution testing. Results: We found matched family donors in 227 (55%) of 412 patients screened at our center. The ratio of HLAmatched related donors was 83% for 279 patients who received allogeneic stem cell transplant. Conclusions: The likelihood of finding eligible unrelated donors has been gradually increasing, in part due to the development of the National Bone Marrow Bank. However, a careful screening for related donors is still important. Our findings indicate the importance of careful examination of family genealogy and of careful family screening in our region.
Granulocyte-Colony Stimulating Factor Administration Among Hemoglobin S Trait Donors: A Single Center Experience from The Eastern Mediterranean Region
(2018) Gereklioglu, Cigdem; Asma, Suheyl; Korur, Asli; Tepebasi, Songul; Aytan, Pelin; Yeral, Mahmut; Kozanoglu, Ilknur; Boga, Can; Ozdogu, Hakan; https://orcid.org/0000-0001-5335-7976; https://orcid.org/0000-0002-5086-5593; https://orcid.org/0000-0002-2553-7715; https://orcid.org/0000-0002-9580-628X; https://orcid.org/0000-0002-5268-1210; https://orcid.org/0000-0002-8902-1283; 28699692; AAI-7831-2021; AAD-5616-2021; AAE-3833-2019; ABC-4148-2020; AAE-1241-2021; AAD-6222-2021; AAD-5542-2021
Background and Objective: Assessment of Hemoglobin S trait donors has gained importance together with the increased allogeneic peripheral stem cell transplant activity for sickle cell disease in the regions where the disease is prevalent. Outcomes of Granulocyte-Colony Stimulating Factor (G-CSF) administration are obscure for hemoglobin S trait donors. This study aims at investigating the incidence of hemoglobin S carrier status and outcomes of G-CSF administration among donors who live in Eastern Mediterranean region. Material and Method: The cross-sectional, single-center cohort study was performed with 147 donors between January 2013 and March 2017. Prevalence of hemoglobin S trait was estimated and subjects with or without Hemogobin S trait were compared with regard to stem cell characteristics, early and late clinical outcomes after G-CSF administration. Results: Eleven out of 147 donors (7.48%) were found as hemoglobin S trait. G-CSF administration was successfully completed and yielded good harvesting results in hemoglobin S trait donors. No statistically significant difference was found between groups with regard to early and late side effects, stem cell characteristics. Blood pressures and QTc values were within normal ranges in both groups. Groups were similar with regard to CD34 values. Conclusion: 1G-CSF seems safe in hemoglobin S trait donors. Their being eligible as donors would increase the chance of the patients for allogeneic stem cell transplantation in high prevalence regions.

Background: 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.

(2016) Gereklioglu, Cigdem; Asma, Suheyl; Konur, Asli; Erdogan, Ferit; Kut, Altug; 27375698
Objective: This study aimed at investigating the factors affecting medication adherence in patients who use oral iron therapy due to iron deficiency anemia. Methods: A total of 96 female patients in fertile age with mean age of 30 +/- 10.1 years (range 18-53) who were admitted to Family Medicine Clinic between 01 January and 31 March 2015 and who had received iron therapy within the recent three years were enrolled in the study. Data were collected through a questionnaire form. Results: Of the patients, 39 (40,6%) were detected not to use the medication regularly or during the recommended period. A statistically significant relationship was found between non-adherence to therapy and gastrointestinal side effects and weight gain (p<0.05). Conclusion: Medication adherence is deficient in patients with iron deficiency anemia. The most important reason for this seems gastrointestinal side effects, in addition to weight gain under treatment.

The aim of this study is to assess the cases of nonhematologic maiignancies that had bone marrow (BM) metastasis with respect to hematologic abnormalities, radiologic findings and pathologic findings. All of the patients with BM investigation were retrospectively evaluated. The patients with BM metastasis by a non-hematologic malignancy were assessed. Data regarding patient characteristics including peripheral blood evaluation findings, imaging findings, BM evaluation results and survival were obtained from patient files and computer based electronic database. 30 cases were detected among 1831 BM aspirations and biopsies. The most common malignancies were breast (36.7%), prostate (13.3%), gastric(13.3%) and lung (13.3%) adenocarcinomas. 90.9% and 75% of the cases had positive radiologic findings with PET/CT and CT respectively. 43.3% of the patients died during the study period and the median time from BM assessment to death was 2 months. Anemia, thrombocytopenia and leukopenia were present in 90%, 73.3% and 20% respectively. Lactate dehydrogenase and alkaline phosphatase were elevated in 90% and 80% respectively. In 76.2% a leukoerythroblastic blood picture was present. All the cases were diagnosed with biopsy and aspiration detected infiltration in 40% and in 4 metastatic patients (13.3%) the aspiration was false negative. In 46.7% the aspiration resulted with dry tap. Grade 3 fibrosis was present in 76.7%. BM assessment is a minimally invasive technique and provides very beneficial clinical data, however, because the survival is very short after BM assessment and the PET/CT has a considerable sensitivity it is not necessary to confirm BM metastasis in patients whose tumor stage is already known.

The 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.

Acute poisoning is an important cause of morbidity and mortality during childhood. This manuscript reports the positive outcome of a pediatric case with a history of accidental carbamazepine intake treated using plasma exchange. A 3-year-old male presented with severe carbamazepine intoxication. He was comatose and had generalized tonic clonic seizure, ventricular tachycardia, and hypotension. Although he did not respond to classical therapies, we performed two sessions of plasma exchange. The patient recovered rapidly and was discharged from the hospital six days from the time of carbamazepine ingestion with no complication or neurologic impairment. Plasma exchange can be performed safely in very small children, and it might be the first line treatment, particularly for intoxication with drugs that have high plasma-protein-binding properties.
