RESUMEN

Background & Objective: The prevalence of obesity is gradually increasing in our country and worldwide. Being obese and overweight are risk factors for chronic diseases. Obesity has a multifactorial etiology, so treatment should involve lifestyle changes, psychological strategies, pharmacologic treatment, and bariatric surgery. The present study aimed to investigate the effectiveness of the trans-theoretical stages of change (TTM SOC) model in managing adult obese and overweight patients. Methods: This prospective cohort study was conducted with 133 adults who were admitted to the Family Medicine Outpatient Clinic of Adana City Research and Training Hospital between April 1, 2017, and April 30, 2019. Socio-demographic characteristics, blood pressures, anthropometric measurements, and laboratory data were compared between the baseline and the first, third, and sixth months. Results: Body mass index (BMI) was higher among those with a low educational level. The mean age, the number of medications used, and the metabolic parameter values were significantly lower among the participants who did not have a chronic disease. Blood pressures, weight, BMI, plasma glucose and insulin, HOMA-IR, and triglyceride were statistically significantly higher at the baseline compared to follow-up values. Fasting plasma glucose was higher at the baseline in diabetic patients. The results were compared with Student t and One Way ANOVA tests. The Pearson correlation coefficient was used to demonstrate the association between baseline and repeated metabolic measurements. Conclusion: The trans-theoretical model is effective in managing adult obese and overweight individuals and also in glycemic control in obese Type-2 diabetics.

RESUMEN

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. He-moglobin (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.

RESUMEN

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: G-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. Further studies are required to reveal the safety profile of G-SCF in hemoglobin S carriers in different regions.

RESUMEN

BACKGROUND AND AIM: Today, voluntary donation of peripheral blood stem cells by healthy donors for allogeneic hemopoietic cell transplantation is common worldwide. Such donations are associated with small but measurable risks of morbidity and mortality. Most complications are associated with citrate infusion during cell collection. We studied the effects of citrate infusion on the QTc and other vital parameters during and after peripheral stem cell apheresis in volunteers. METHOD: To ensure that donors were healthy, screening included taking a detailed medical history, physical examination, and laboratory measurements of plasma calcium and magnesium. Corrected QT (QTc) values were assessed using a 12-lead electrocardiographic platform that derived QTc values automatically. RESULTS: In all, 141 apheresis procedures were performed. The mean QTc values at baseline, at 2 and 4 h during the procedure, and at 30 min after the procedure, were 347.6 ± 59.5, 349.9 ± 52.8, 391.8 ± 54.0, and 404.8 ± 59.2 ms, respectively. The baseline and 2 h QTcs did not differ significantly, but the baseline QTc did differ significantly from the 4 h and 30 min after the procedure values. The plasma levels of calcium and magnesium did not significantly differ before and after the procedure. CONCLUSION: QTc prolongation may develop during leukopheresis, particularly if the procedure takes more than 2 h. Thus, to enhance donor safety, QTc measurement should be standard for all donors. In addition, any family history of sudden death should be noted, to prevent the development of possible fatal arrhythmia in susceptible donors.

RESUMEN

OBJECTIVE: In this study, we investigated the influence of electronic health records (EHR) and electronic vaccination schedule applications on the vaccination status of patients who were admitted to our Center for the treatment of sickle cell disease (SCD). METHODS: The vaccination status against influenza and pneumococcus infection was determined in 93 patients who were admitted to the hematology outpatient clinic, Baskent University Adana Hospital from April 2004 to March 2009. The vaccination status was then re-evaluated following establishment of EHR and electronic vaccination schedules in 2012. RESULTS: Of the 93 patients with SCD 21.5% (n = 20) were vaccinated against pneumococcus and 21.5% (n = 20) were regularly vaccinated against influenza. When the vaccination rates of 59 of 93 patients who presented for their regular control examinations were analyzed following establishment of EHR and vaccination schedules in 2012, these rates were 49.2% (n = 29) and 50.8% (n = 30) for influenza and pneumococcus, respectively, after EHR; there were 23.7% (n = 14) and 20.3% (n = 12), respectively, before EHR. A statistically significant difference was found between the vaccination rates before and after EHR (p < 0.05). CONCLUSION: Although viral and bacterial infections are life-threatening health problems in patients with SCD, the vaccination rates were low in high-risk patients. However, these rates increased after application of electronic vaccination schedules.

RESUMEN

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-ß(0) thalassemia (17 %), Hgb S-ß(+) thalassemia (15 %), and Hb S-α 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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

BACKGROUND: Sickle cell disease (SCD) is associated with chronic hemolysis and painful episodes. Pregnancy accelerates sickle cell complications, including prepartum and postpartum vasoocclusive crisis, pulmonary complications, and preeclampsia or eclampsia. Fetal complications include preterm birth and its associated risks, intrauterine growth restriction, and a high rate of perinatal mortality. The purpose of this study was to evaluate pregnancy outcomes in patients with SCD who underwent planned preventive red blood cell exchange (RBCX). STUDY DESIGN AND METHODS: We retrospectively evaluated the complications of SCD in 37 pregnant patients. Patients with SCD who had undergone prophylactic RBCX were compared with a control group who had not undergone RBCX during pregnancy. RESULTS: Forty-three exchange procedures were performed in 24 patients. The control group comprised 13 patients with a mean age of 27.4 ± 3.3 years who had not undergone RBCX during pregnancy. Four of the five patients who developed a vasoocclusive crisis died. There was a significant difference in maternal mortality between the study and control groups (p = 0.011). There was also a significant difference in the incidence of vasoocclusive crisis between the study and control groups. One fetal death occurred in the 20th gestational week in a patient in the control group, although there were no postpartum complications in either the babies or the mothers in the control group. CONCLUSION: This study has demonstrated that prophylactic RBCX during pregnancy is a feasible and safe procedure for prevention of complications. Given the decrease in the risks of transfusion, RBCX warrants further study.

RESUMEN

Objective: Osteoporosis is a substantial global public health issue. The objective of this study was to evaluate the risk variables associated with osteoporosis among patients seeking care at an outpatient menopausal clinic in a tertiary university hospital. Material and Methods: In this retrospective, cross-sectional study postmenopausal women who attended the outpatient menopause clinic of Baskent University Hospital between June 01, 2014, and August 31, 2015, were enrolled. Patients' datasheets were reviewed and data including age, body mass index, parity, duration and age of menopause, history of smoking and oral contraceptive pills (OCPs) use, natural or surgical menopause, and calcium-containing food consumption were collected through a standardized questionnaire. Bone mineral density (BMD) was measured at the femur neck and lumbar spine by dual energy X-ray absorptiometry. Results: A total of 1,148 women with a mean age of 53.5±6.7 years, mean duration of menopause 7.1±6.2 years and mean age of menopause 46.3±5.1 years were identified. Of these, 235 (20.5%) were diagnosed as having osteoporosis. The average femur and lumbar T-values showed a decrease in normal weight patients compared to overweight, obese, and morbidly obese patients (F=22,337, p<0.001 and F=50,195, p<0.001, respectively). The mean femur T-values were higher in participants who used OCPs, regularly consumed a calcium-rich diet, and performed regular physical activity (p<0.05, p<0.01 and p<0.05). Positive correlations were noted between giving birth and femur T-values (r=0.065, p=0.027), between natural menopause and lumbar T-values (r=0.060, p=0.043), and between consuming a calcium-rich diet and femur T-values (r=0.087, p=0.003 and r=0.064, p=0.031, respectively). Conclusion: Using OCPs, lifelong physical activity, and a healthy diet rich in calcium are important factors for the prevention of low lumbar spine and femoral BMD and by implication, osteoporosis.

RESUMEN

Transplant physicians should be aware of the immune deviation-related clinical conditions as allogeneic hematopoietic stem cell transplantation is widely used for the treatment of patients with malignant and non-malignant disorders. Neurological manifestations and graft-versus-host disease (GVHD) may commonly develop in transplant recipients. However, overlapping clinical immunological conditions may lead to diagnostic challenges. Herein, we discussed the differential diagnosis of a patient with immune reconstitution inflammatory syndrome (IRIS) developing on the basis of chronic GVHD.

RESUMEN

OBJECTIVES: Patients with adult sickle cell disease and severe sequelae are treated with nonmyeloablative allogeneic hematopoietic stem cell transplant. So far, data on gonadal effects are lacking for older cured patients. We assessed the gonadal reserve and sexual function of patients cured of sickle cell disease with transplant and with anti-T-lymphocyte globulin and posttransplant cyclophosphamide-containing regimen within the context of the Baskent Organ Damage Mitigation and Medical Care Development Program. MATERIALS AND METHODS: All adult patients (≥18 years) with sickle cell disease who underwent peripheral stem cell transplant from September 2013 to July 2019 and were graft-versus-host disease free for 2 years and not immunosuppressed were invited to participate in this prospective observational study. Of 61 eligible patients, 43 participants (~10% from international registries) were included (median age at transplant was 29 years; range, 18-45 years). Gonadal status, risk of gonadal damage posttransplant, conception, and sexual function posttransplant were evaluated. RESULTS: Allogeneic hematopoietic stem cell transplant was associated with increased risk of secondary amenorrhea (odds ratio of 93; 95% CI, 4.94-17.50; P = .002) and ovarian insufficiency (odds ratio of 37.8; 95% CI, 2.03 to -700.94; P = .014) but not with female sexual dysfunction. Secondary ovarian insufficiency developed in all women posttransplant. Transplant was associated with significant risk of azoospermia (odds ratio of 4.35; 95% CI, 1.02-18.45; P = .017). Moderate-to-severe erectile dysfunction developed in 2 men (10%). Among female participants, 1 had spontaneous conception that ended in miscarriage and 1 had term delivery after in vitro fertilization. Among male participants, 1 had a child by in vitro fertilization and 1 experienced spontaneous conception. CONCLUSIONS: Although spontaneous conception was shown in our patient group, gonadal damage was evident at >2 years posttransplant. This risk was associated with age in female patients. Better fertility preservation measures should be incorporated into medical care development programs.

RESUMEN

OBJECTIVES: Reluctance of families of deceased donors to provide approval for donation is a factor in low rates of deceased donor organ transplants. Decisions of women may be important for family approval. We investigated the influence of knowledge and beliefs of housewives on attitudes toward organ donation. MATERIALS AND METHODS: This cross-sectional study was conducted with 212 housewives attending Directorate of Religious Affairs centers and public education centers in Adana province between May and June 2018. A structured questionnaire to assess sociode-mographic information, knowledge, and beliefs about organ donation, as well as the Attitudes Toward Organ Donation Scale, was applied through face-to-face interviews. RESULTS: Mean age of participants was 42.9 ± 13.1 years, 68 (32.1%) had no formal education, and 125 women (59.0%) identified as low income. Of the women, 40 (18.9%) were single, 147 (69.3%) were married, 25 (11.8%) were divorced∕widowed, 104 (49.1%) were attending religious affairs centers, and 108 (50.9%) were attending public education centers. Mean score for the question "What is the religious drawback of donating organs?" was significantly higher in participants attending a Quran course (2.5 ± 1.4), and mean score of Attitudes Toward Organ Donation Scale decreased significantly as mean score for this question increased; the score for "Are you aware that the organ donation-related procedures are conducted within the law?" was 2.2 ± 1.2 (P < .001). Scores increased as knowledge level increased (r = 0.360, P < .001), and scores decreased as perception of organ donation as religiously objectionable increased (r = -0.258, P < .001). CONCLUSIONS: Participants with sufficient knowledge about organ donation, without religious objection to organ donation, and with awareness of the lawful status of organ donation had positive attitudes toward organ donation. Efforts toward improvement of community knowledge could increase rates of deceased donor organ donation.

RESUMEN

Sickle cell disease is the most common genetic disorder in the Eastern Mediterranean region where our transplant center is located. Today, adult patients with sickle cell disease can also be successfully treated with allogeneic hematopoietic stem cell transplantation. Bone marrow necrosis is a rare and serious clinical condition. Herein, we present this complication for the first time in the literature, which developed in the course of allogeneic hematopoietic stem cell transplantation and was successfully managed with additional bone marrow support. The recognition, prevention, and management of this rare and potentially fatal complication, bone marrow necrosis, are vitally important, especially in regions with high prevalence of sickle cell disease.

RESUMEN

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 con-ditioning 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.

RESUMEN

OBJECTIVES: Our aim was to compare patients with high-risk chronic lymphocytic leukemia referred to our transplant center who underwent allogeneic stem cell transplant with those who did not receive this treatment. Factors compared included demographics, clinical characteristics, and survival rates in the novel targeted therapy era. MATERIALS AND METHODS: All 33 patients with high-risk chronic lymphocytic leukemia who were referred to the hematopoietic stem cell transplant center were enrolled in this retrospective, single-center nonrandomized study. Outcomes of patients who received allogeneic stem cell transplant were compared with those of nontransplant patients. Chemoimmunotherapy and ibrutinib were given when indicated. Factors related to overall and progression-free survival were assessed. RESULTS: Thirteen patients underwent allotransplant, and transplant was not done in 20 patients for various reasons. Demographic and clinical features of the transplant and nontransplant groups were similar. The estimated cumulative overall survival was 72.6 ± 15 and 84.3 ± 13 months in the nontransplant and transplant groups, respectively. The 5-year overall and progression-free survival rates in the transplant and nontransplant groups were 57.3%/36.0% and 40%/20.6%, respectively. In the nontransplant group, overall survival of those who used ibrutinib was longer than overall survival in patients in the transplant group who used the same drug, but the difference was not statistically significant. Although not significant, overall survival in patients who did not use ibrutinib was longer in the transplant group than in the nontransplant group. Cox regression analyses showed that transplant, relapse, and Binet stage were independent predictors of overall survival. CONCLUSIONS: In patients who do not use ibrutinib, allogeneic stem cell transplant improved survival compared with nontransplant patients. Addition of ibrutinib provided comparable life expectancies, showing that allogeneic stem cell transplant and ibrutinib may have complementary roles. Transplant is still an independent predictor of overall survival.

RESUMEN

OBJECTIVES: The aim of the present study was to investigate suicidal ideation and dissociative experiences and to predict demographic and clinical risk factors during isolation periods in patients undergoing hematopoietic stem cell transplant. MATERIALS AND METHODS: Our study included 61 consecutive stem cell recipients (29 autologous, 32 allogeneic). Patients were evaluated with the Suicidal Ideation Scale, Dissociative Experiences Scale, Hamilton Depression Scale, Hamilton Anxiety Scale, and State Trait Anxiety Inventory. RESULTS: The transplant procedure did not influence the Dissociative Experiences or Suicidal Ideation Scales (P > .05). However, patients had higher anxiety and depression levels at time of discharge (P < .001). Suicidal ideation scores were correlated with higher Hamilton Depression Scale, State Trait Anxiety Inventory, and Dissociative Experiences Scale scores on admission (P < .05), with the latter 2 scores also higher at the time of discharge in patients who received radiotherapy prior to transplant (P < .05). CONCLUSIONS: Suicidal ideation and dissociative experiences, which may emerge because of complex and traumatic processes, should be considered by clinicians. Social and psychological support should be provided for patients undergoing hematopoietic stem cell transplant.

RESUMEN

OBJECTIVE/BACKGROUND: Anti-T lymphocyte globulin Fresenius (rATG-F; ATG-Fresenius) and antithymocyte globulin (thymoglobulin), which are included in transplant protocols, are used to reduce the risk of chronic graft-versus-host disease (cGVHD) or suppress allograft rejection. Available clinical studies have been conducted in heterogenous patient populations and with different administration protocols including stem cell sources. Additionally, the pharmacokinetics of ATG is variable, and the clinically effective dose of rATG-F, in particular, is not exactly known. The aim of the study was to investigate the clinical outcomes of acute myeloid leukemia (AML) patients who underwent hemopoietic peripheral stem cell transplantation from full-matched sibling donors and given two different doses of r-ATG-F. METHODS: This was a single-center, retrospective chart review conducted between July 2005 and July 2016. Sixty-nine consecutive AML patients who underwent transplant with fludarabine- and busulfan-based conditioning were included in the study. Patients in Group 1 received 15 mg/kg body weight rATG-F to 2013 (n = 46), and Group 2 received 30 mg/kg of rATG-F dose begining in 2013 to reduce to cGVHD (n = 23). Cyclosporine and methotrexate were used to treat acute GVHD (aGVHD) prophylaxis. Outcome parameters were compared between the groups. RESULTS: Although the recommended dose r-ATG-F had led to a decrease in the cumulative incidence of cGVHD (27 [58.7%] vs. 8 [34.8%]; p = .03), it also increased the infection rate at 1 year (3 [6.5%] vs. 4 [17.4%]; p = .02). The two groups were similar in terms of engraftment time, aGVHD, relapse, nonrelapse mortality, and rATG-F-related toxicity. A Cox regression model revealed that aGVHD III-IV was associated with increased nonrelapse mortality at 1 year (hazard ratio = 18.2; 95% confidence interval, 1.667-199.255; p = <.02). No patients developed rATG-F-related severe adverse events (Common Terminology Criteria grade 4 or 5). CONCLUSION: Dose difference of rATG-F did not influence survival parameters; however, increasing the dose to 30 mg/kg seems to be effective for reducing cGVHD with an increase in infection rate requiring close monitoring of infections in AML patients who received myeloablative fludarabine/busulfan conditioning.

RESUMEN

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 highresolution 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.
