Repeated Biting by a Mediterranean Loggerhead Sea Turtle.

Mediterranean loggerhead sea turtles (Caretta caretta) are very large. During spawning season, they land on the beaches of Turkey and Greece at night, which are frequently visited by humans, and lay their eggs. Typically, they suck feed in deep water. It is uncommon for C caretta, which have strong mouths and jaws, to attack people. We report a case of a 44-y-old female patient who was attacked by a turtle on the Mediterranean beach in September 2020. She was brought to the emergency department, where she was noted to have a deep cut on the thumb and large bruises on the left side of her waist. The patient was discharged with appropriate wound care, antibacterial drug, and tetanus vaccine. The wound healed within a few months by developing granulation tissue. However, this report draws attention to the fact that, under some circumstances, C caretta can become aggressive toward people swimming off heavily populated beaches.

Comparison of the clinical course of COVID-19 infection in sickle cell disease patients with healthcare professionals.

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.

Role of prophylactic and therapeutic red blood cell exchange in pregnancy with sickle cell disease: Maternal and perinatal outcomes.

BACKGROUND AND AIM: The incidence of fetomaternal complications during pregnancy is high for women with sickle cell disease (SCD), which is the most common hematologic genetic disorder worldwide. Prophylactic red blood cell exchange (pRBCX) has been shown to be efficient, safe, and feasible for preventing complications. The aim of this study was to observe maternal, perinatal, and neonatal outcomes of pregnancies in which pRBCX was. METHOD: This was a single-center, retrospective, cross-sectional study, which recruited 46 consecutive adult pregnant women with SCD between January 2012 and June 2019. Obstetric features, SCD-related complications, and fetomaternal outcomes were compared between the 27 patients who received prophylactic exchange and the 19 who did not (therapeutic exchange was performed in 7 and was not performed in 12 cases). RESULTS: Painful crises, preeclampsia, and preterm birth rates were significantly higher in the group that did not receive prophylactic exchange (control group; P = .001, P = .024, and P = .027, respectively). There was one maternal mortality in the control group (P = .41). Incidence of adverse fetal or maternal complications was significantly higher in the control group (P = .044 and P = .007, respectively). CONCLUSIONS: Our center's experience over a 7.5-year period, as described above, demonstrates that pRBCX in SCD affects the course of pregnancy positively by ameliorating negative fetomaternal outcomes.

The Impact of the Ferric Carboxymaltose on Hemoglobin and Ferritin Levels.

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.

Granulocyte-colony stimulating factor administration among hemoglobin S trait donors: A single center experience from the Eastern Mediterranean region.

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.

QTc prolongation during peripheral stem cell apheresis in healthy volunteers.

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.

Significance of electronic health records: A comparative study of vaccination rates in patients with sickle cell disease.

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.

East Mediterranean region sickle cell disease mortality trial: retrospective multicenter cohort analysis of 735 patients.

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.

Factors effecting influenza vaccination uptake among health care workers: a multi-center cross-sectional study.

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.

Medication adherence to oral iron therapy in patients with iron deficiency anemia.

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.

Prophylactic red blood cell exchange may be beneficial in the management of sickle cell disease in pregnancy.

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.

Clinical significance of circulating blood and endothelial cell microparticles in sickle-cell disease.

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.

Short-term central venous catheter complications in patients with sickle cell disease who undergo apheresis.

Patients with sickle cell disease (SCD) are prone to develop thrombosis and infection due to their inflammatory and immune deficiency state. These patients require red cell exchange therapy for treatment or prevention of hemoglobin S associated complications. Owing to vascular access problems, adult patients need central venous catheterization (CVC) for exchange procedures. Procedure related complications have been reported for long-term CVCs in pediatric patients. However, short-term CVC complications in adult patients are not clear. This report represents the results of documented complications of short-term CVCs in patients with SCD who undergo apheresis. A total of 142 non-tunneled catheters with average median diameter of 9 F (range 8-16 F) were implanted for apheresis. The catheters were mainly inserted through the right internal jugular vein (66.2 %). Total days of catheter were 412. Results were reported as a complication rate and event according to 1,000 catheter days and compared to a control group including 37 healthy stem cell donors. In the patient group, 1 (1 %) hematoma and 1 (1 %) infection were observed for internal jugular vein catheterization (3.7 hemorrhages and 3.7 infections according to 1,000 catheter days), whereas four (8.9 %) cases of thrombosis and 1 (2.2 %) infection (27 and 6.9 according to 1,000 catheter days) developed in femoral vein. There was a significant difference in terms of thrombosis (P = 0.009). In the control group, only individual developed thrombosis in internal jugular vein. Short-term CVC inserted through to the internal jugular vein seems to be safer than femoral vein in patients with SCD.

Plasma-exchange treatment for severe carbamazepine intoxication: a case study.

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.

[An unusual cause of febrile neutropenia: brucellosis]. / Nötropenik atesin ender bir nedeni: Bruselloz.

Febrile neutropenia which is a common complication of cancer treatment, is one of the major causes of morbidity and mortality. Several gram-negative and gram-positive bacteria are responsible for infections in neutropenic patients, however the most common microorganisms are Escherichia coli and coagulase-negative staphylococci, in decreasing order. Although Brucella spp. infections are endemic in Turkey, brucellosis-related febrile neutropenia has only rarely been reported. In this report, a case of brucellosis-related febrile neutropenia in a patient with acute myeloblastic leukemia (AML) was presented. A 56-year-old male patient presenting with fever, petechiae/purpura, leukocytosis, thrombocytopenia, and anemia was admitted to our hospital. Laboratory studies revealed a hemoglobin level of 8.27 g/dl, leukocyte count of 77.100 k/ml, absolute neutrophil count of 200 k/ml, and platelets at 94.200 k/ml. The patient was diagnosed as AML-M1 and piperacillin/tazobactam was started as the first-line antibiotic therapy due to the febrile neutropenia. On admission, blood and urine cultures were negative. Once the fever was controlled, remission/induction chemotherapy was initiated. However, fever developed again on the eight day, and vancomycin was added to the therapy. Since the fever persisted, the antibiotic therapy was gradually replaced with meropenem and linezolid. However, fever continued and the patient's general condition deteriorated. Subsequently performed Brucella tube agglutination test revealed positivity at 1/320 titer and the microorganism grown in blood culture (Bactec 9050; BD, USA) was identified as B.melitensis by conventional methods. Rifampicin and doxycycline therapy was started immediately, however, the patient died due to septic shock. If the tests for brucellosis were performed earlier when response to second step antibiotic therapy lacked in this patient, it was assumed that mortality could be prevented by the prompt initiation of the appropriate treatment. Thus, since brucellosis is endemic in Turkey, it should be considered as a possible agent of febrile neutropenia especially in patients unresponsive to empiric antibiotherapy and appropriate diagnostic tests should be performed.

Assessment of Stem Cell Transplant Eligibility in Recipients with Oral Foci of Infection: Appropriate Conditioning Regimens.

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.

Gonadal Status and Sexual Function at Long-Term Follow-up after Allogeneic Stem Cell Transplantation in Adult Patients with Sickle Cell Disease.

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.

Comparison of Outcomes of Transplant and Nontransplant High-Risk Chronic Lymphocytic Leukemia Patients in the Novel Targeted Therapy Era.

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.

Is It Possible to be a Stem Cell Donor for the Second Time: A Single-Center Report of 12 Consecutive Procedures.

OBJECTIVES: The use of unrelated donors as a source of stem cells for patients with blood disorders continues to increase. Approximately 5% to 7% of unrelated stem cell donors are asked to donate stem cells a subsequent time to the same or a different patient. We investigated donors who accepted to be a donor for the second time between 2015 and 2021; donors were evaluated in terms of procedure-related complications, product quality, and donor follow-up in a JACIEaccredited (Joint Accreditation Committee of the International Society for Cellular Therapy and European Society for Blood and Marrow Transplantation). MATERIALS AND METHODS: Stem cell collections were performed in accordance with relevant standard operating procedures from healthy volunteer donors. Data on sequence of peripheral blood stem cell, bone marrow, and donor lymphocyte collection procedures; presence of complications during procedures; time between 2 donations; need for granulocyte colonystimulating factor again; and first and second donation types were noted. Data on donor and stem cell products were determined using the hospital information management system. RESULTS: Our study included 12 donors (9 men and 3 women) who donated a second time within the specified date range. In the evaluation of the second donation types, 7 were lymphocyte collection donations, 4 were peripheral blood stem cell donations, and 1 was a bone marrow stem cell donation. In shortterm and long-term follow-ups, there were no complications among the donors. In the second donations, targeted product values were reached. CONCLUSIONS: Although it is safe to have a second donation from a donor for the same patient, collection centers may collect more products than requested from eligible donors.

Factors Associated With Overall Survival in Acute Myeloid Leukemia Patients Before and After Hematopoietic Stem Cell Transplant.

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.
