RESUMEN

Cannabinoids bind to cannabinoid receptors CB1 and CB2 and their antitumoral activity has been reported against some various cancer cell lines. Some synthetic cannabinoids possessing indole rings such as JWH-015 and JWH-133 particularly bind to the cannabinoid CB2 receptor and it was reported that they inhibit the proliferation and growth of various cancer cells without their psychoactive effects. However, the pharmacological action mechanisms of the cannabinoids are completely unknown. In this study, we report the synthesis of some new cannabinoidic novel indoles and evaluate their anticancer activity on various cancerous and normal cell lines (U87, RPMI 8226, HL60 and L929) using several cellular and molecular assays including MTT assay, real-time q-PCR, scratch assay, DAPI assay, Annexin V-PE/7AAD staining, caspase3/7 activity tests. Our findings indicated that compounds 7, 10, 13, 16, and 17 could reduce cell viability effectively. Compound 17 markedly increased proapoptotic genes (BAX, BAD, and BIM), tumor suppressor gene (p53) expression levels as well as the BAX/BCL-2 ratio in U87 cells. In addition, 17 inhibited cell migration. Based on these results, 17 was chosen for determining the mechanism of cell death in U87 cells. DAPI and Annexin V-7AAD staining results showed that 17 induced apoptosis, moreover activated caspase 3/7 significantly. Hence, compound 17, was selected as a lead compound for further pharmacomodulation. To rationalize the observed biological activities of 17, our study also included a comprehensive analysis using molecular docking and MD simulations. This integrative approach revealed that 17 fits tightly into the active site of the CB2 receptor and is involved in key interactions that may be responsible for its anti-proliferative effects.

RESUMEN

Indazole scaffold have two interconvertible tautomeric forms. Regioselectivities were determined for N-benzylations and alkylation of some non-substituted and substituted indazoles, under basic conditions (K2CO3) in DMF. The ratio of regioisomers occurrence between N1:N2 is almost equal. Their structures were established through a combination of NOESY and 1H-13C/15N HMBC NMR methods. Additionally, pyrazolo[3,4-b]pyridines have also three possible tautomeric forms; primarily 1H and 2H, with 7H isomers being rare. Pyrazolo[4,3-b]pyridines have only known two possible tautomeric forms so far; 1H and 2H.

RESUMEN

The synthesis of 5H-imidazo[4,5-c]pyridines analogues (1a - 1h) and 4H-imidazo[4,5-b]pyridines (3a - 3c) was achieved by reacting 3,4-diaminopyridine or 2,3-diaminopyridine with Na2S2O5 adduct of corresponding benzaldehydes (a1 - a8). Alkylation of compounds (1a - 1h) and (3a - 3c) using 4-chlorobenzyl and /or butyl bromide under basic conditions (K2CO3, DMF) predominantly resulted in the formation of N5 regioisomers (2a - 2l) and N4,3 regioisomers (4a - 4c1,2), respectively. The N5,4,3-regioisomeric structures were confirmed using 2D-NOESY (Nuclear Overhauser Effect Spectroscopy) and HMBC (Heteronuclear Multiple Bond Correlation) spectra. The antibacterial and antifungal activities of the synthesized compounds (2a - 2g, 4a - 5d) were evaluated in vitro against Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus, Methicillin resistant S. aureus, Enterococcus faecalis and Candida albicans, Candida parapsilosis. Among the synthesized compounds, promising activities were observed with compounds 2g, 2h, 4a and 4b with lowest MIC values (4-8 µg/mL). The compounds 2i, 2j, 2k, 2l showed moderate activity. Additionally, a computational approach (ADMETlab 2.0) was used to evaluate the drug likeness properties of the compounds.

RESUMEN

INTRODUCTION: Bortezomib is the first chemotherapeutic agent of proteosome inhibitor class that can be used in newly diagnosed and relapsed/refractory multiple myeloma. It is well known that bortezomib has side effects such as peripheral sensory, motor, or autonomic neuropathy. In this paper, we will present our patient who developed unilateral phrenic nerve palsy as an autonomic neuropathy after six cycles of subcutaneous bortezomib treatment. This case differs from other cases in that our patient was asymptomatic. CASE REPORT: A 57-year-old male patient was admitted with back pain and gait disturbances. In the thorax computed tomography, a soft tissue mass causing compression on the spinal canal was observed in the T12 vertebra. Bone biopsy pathology report resulted in diffuse plasma cell infiltration. The patient was diagnosed with stage ISS-3, IgG kappa type multiple myeloma. MANAGEMENT AND OUTCOME: Subcutaneous bortezomib 1 × 2.2 mg (Days 1-4-8-11) + intravenous cyclophosphamide 1000 mg (Day 1) + intravenous dexamethasone 40 mg (Days 1-2-3-4) (VCD chemotherapy protocol) was started. Totally six cycles of VCD were administered. While the patient did not have any respiratory symptoms, an elevation consistent with phrenic nerve palsy was observed in the left hemidiaphragm in the thorax computed tomography that was taken during the preparation for autologous hematopoietic stem cell transplantation. DISCUSSION: Bortezomib is a frequently used chemotherapeutic agent in patients with multiple myeloma and care should be taken in terms of the risk of developing phrenic nerve palsy in patients. There are cases of autonomic neuropathy developing after bortezomib treatment.

RESUMEN

INTRODUCTION: Tyrosine kinase inhibitors (TKis) and Bruton's TKi (BTKis) constitute broadly used antitumor drug groups with almost completely tolerable and manageable side-effect profiles. Mainly side effects are cardiovascular and gastrointestinal for the TKi group. Hypophosphatemia is documented frequently in many studies with TKis but rarely mentioned with ibrutinib use up to the present. CASE REPORT: A 61-year-old patient with the diagnosis of chronic lymphocytic leukemia had hypophosphatemia-related complaints and symptoms when ibrutinib use was preferred for his second relapse of the disease. After drug discontinuation, we started ibrutinib again with an alternating dose. We managed to control hypophosphatemia, and the patient has been following up for 2 years in remission status without any support or a second drug need. MANAGEMENT AND OUTCOME: We have presented here a chronic lymphocytic leukemia case that developed mild-severe hypophosphatemia associated with ibrutinib use. By using an alternating dose of ibrutinib, we managed to control the disease and drug side effects. DISCUSSION: TKis and BTKis are widely in use for different indications. Hypophosphatemia is rare but it can cause drug discontinuation or change if it is not manageable. It is mentioned that hypophosphatemia can be seen due to a common group effect with the mechanism of causing secondary hyperparathyroidism and renal tubulopathy. In our case, we could explain the side effect of hypophosphatemia with secondary hyperparathyroidism and renal tubulopathy. Prospective, large-group studies are needed to explain the hypophosphatemia and other side effects of ibrutinib and new BTKis in detail.

RESUMEN

BACKGROUND: Since well-designed prospective comparative trials are lacking, haploidentical hematopoietic stem cell transplantations approach should be based on the expertise of a particular center. In this study, we aimed to report the results and outcomes of patients who underwent haploidentical hematopoietic stem cell transplantation. METHODS: : Thirty-nine patients who underwent transplantation in our clinic between 2015 and 2022 were retrospectively analyzed. Primary end point of this study is to find out the survival rates of the patients. RESULTS: The overall survival of patients was 29.9 ± 4.9 months. The disease-free survival of the patients was 37.8 ± 5.7 months. The 3-year overall survival rate of the patients was %50 and the 3-year disease-free survival rate of the patients was %53. Nineteen patients were nonsurvivors among a total of 39 patients. Busulfan-fludarabine-thiotepa was the most frequently used conditioning regimen for transplantation. Busulfan-fludarabin-antithymocyte globulin regimen is the second preferred conditioning regimen. Cyclosporine- cyclophosphamide-mycophenolate mofetil was the most widely used graft-versus-host disease prophylaxis regimen. Sixteen patients had graft-versus-host disease, 28% of the patients had acute graft-versus-host disease, and 13% had chronic graft-versus-host disease. Gastrointestinal system consists of the most involved organs in graft-versus-host disease since 15% of the patients had gastrointestinal graft-versus-host disease. First-degree relatives (parent/child) were the most frequent donor source for haploidentical hematopoietic stem cell transplantation. Sepsis was the most frequent reason of death among transplant patients. DISCUSSION: In our center, we prefer to use high dose posttransplantation cyclophosphamide after haploidentical hematopoietic stem cell transplantation for graft-versus-host disease prophylaxis. With this approach, our center's overall survival and disease-free survival rates are comparable and compatible with the literature findings.

RESUMEN

Thrombotic microanjiopathy (TMA) is a pathological diagnosis characterized by abnormalities of small vessels leading to microvascular thrombosis of arterioles and capillaries. The current prospective, non-interventional, multicenter study aimed to define the distribution of different TMA forms in adult Turkish patients who were referred for therapeutic plasma exchange (TPE) for presumptive diagnosis of TMA. Patients with serum ADAMTS13 activity <5% were diagnosed as having acquired thrombotic thrombocytopenic purpura (aTTP). Patients presenting with ADAMTS13 activity 6-10 % / normal renal function and patients with ADAMTS13 activity >10 %, normal renal function and no secondary TMA were treated as unclassified TMA. The study included a total of 80 patients (women: 50; man: 30) with a median age of 48 (20-74). Detailed evaluation at 1 month after hospital admission revealed aTTP, secondary TMA, infection/complement-associated hemolytic uremic syndrome and unclassified TMA in 29 (36.2 %), 22 (27.5 %), 23 (28.8 %) and 6 (7.5 %) patients respectively. As subclassification of various TMAs will dictate specific therapy, proper diagnosis in a timely manner is of utmost clinical significance.

RESUMEN

OBJECTIVE: The Functional Assessment of Cancer Therapy-Bone Marrow Transplant Version 4 (FACT-BMT) is a widely used instrument to assess quality of life in individuals treated with bone marrow transplantation (BMT). Our aim was to determine the reliability and validity of the Turkish version of the FACT-BMT in patients undergoing BMT. METHOD: Patients between the age of 20 and 65 years and who had undergone BMT at least 3 months before the study were included. Validity was determined using exploratory and confirmatory factor analysis. To determine convergent validity, the European Cancer Research and Treatment Organization Quality of Life Questionnaire-Cancer30 (EORTC QLQ-C30), the Brief Fatigue Inventory (BFI), and the Eastern Cooperative Oncology Group (ECOG) performance score were used. Cronbach's alpha, intra-class correlation coefficient (ICC), and item-total correlation (ITC) values were calculated to assess the reliability of the FACT-BMT. RESULTS: Totally, 114 patients (F/M: 47/67) treated with BMT (mean age: 49.50 ± 12.50 years) were included. Confirmatory and exploratory factor analysis revealed that the FACT-BMT and the Bone Marrow Transplantation Subscale (BMTS) had sufficient fit. The FACT-BMT was moderately to strongly correlated with the EORTC QLQ-C30, the BFI, and the ECOG performance score (p < 0.001). Cronbach's alpha and ICC values of the FACT-BMT were acceptable (0.925 and 0.956, respectively). The ITC values of each item of the FACT-BMT were also acceptable (ranged from 0.296 to 0.737). Patients undergoing autologous BMT had a significantly higher BMTS score than those undergoing allogeneic BMT (p < 0.05). SIGNIFICANCE OF RESULTS: The Turkish version of the FACT-BMT is valid, reliable, and sensitive to changes in quality of life in patients undergoing BMT.

RESUMEN

The SARS-CoV-2 spike protein mRNA-based vaccines have prevented countless mortality and morbidity, and have an excellent risk/benefit ratio. However, various adverse events may rarely occur after the BNT162b2 vaccine, like any other medical intervention. The COVID-19 itself and the spike protein produced endogenously by mRNA vaccines may have immunological, microenvironmental, prothrombotic, and neoplastic effects. As a contribution to the published report, we would like to share our experience regarding four cases in which myeloid neoplasms emerged following the vaccination. Conclusions: There is no doubt that vaccination could continue along the lines of established universal recommendations. Meanwhile, all hematological adverse events must be closely monitored and reported. Further efforts should be focused on the probable pathobiological mechanisms and causalities of spike protein-related toxicity and clonal myeloid disorders.

RESUMEN

BACKGROUND: Thrombocytopenia is a common complication following hematopoietic stem cell transplantation (HSCT). Eltrombopag has been used in thrombocytopenia treatment after HSCT in recent years. Herein, we present our experience of 25 patients treated with eltrombopag for post-HSCT thrombocytopenia. METHODS: Fifteen autologous hematopoietic stem cell transplantation (AHSCT) and 10 allogenic hematopoietic stem cell transplantation (allo-HSCT) recipients treated with eltrombopag for treatment of prolonged isolated thrombocytopenia (PIT) or secondary failure of platelet recovery (SFPR) in the stem cell transplantation unit of Hacettepe University Hematology Department between 2017 and 2021 were included in the study. The primary endpoint of this study is eltrombopag response in patients diagnosed with PIT or SFPR. Platelet count above 50,000/mm3 for five consecutive days without platelet transfusion was considered as eltrombopag response. Overall survival (OS) analyses were calculated based on the time between HSCT and death from any cause. The patients who were alive at the last follow-up were censored at this time for calculation of OS analyses. RESULTS: AHSCT (66.7% (10/15)) and allo-HSCT (50% (5/10)) recipients responded to eltrombopag for the treatment of post-HSCT thrombocytopenia. There was no excess toxicity related to the eltrombopag use. The median response duration of allo-HSCT recipients and AHSCT recipients were 41 (13-104) days and 50 (7-342) days, respectively. There was a statistically significant OS duration difference between the responders and nonresponders in allo-HSCT and AHSCT recipients with p values of 0.005 and 0.02, respectively. DISCUSSION: Eltrombopag is promising for the treatment of thrombocytopenia after AHSCT and allo-HSCT in terms of efficacy and safety.

RESUMEN

OBJECTIVE: Aplastic anemia (AA) is a life-threatening disorder and may be associated with significant morbidity and mortality Currently, the first treatment option is allogeneic hematopoietic stem cell transplant (allo-HSCT) for patients younger than 40 years. Bone marrow is recommended as the stem cell source due to less graft versus host disease (GVHD) risk and better outcomes than peripheral blood (PB)-derived stem cell. The aim of this study is to share the data of AA patients who have underwent PB-derived allo-HSCT in our bone marrow transplantation center. METHODS: Twenty-seven patients who underwent PB-derived allo-HSCT from human leukocyte antigen matched sibling donors were analyzed retrospectively. RESULTS: The median follow-up time was 95.2 months (range, 4.8-235 months). The 10-year survival was 89 %. The median neutrophil and platelet engraftment time was 11 days (range, 9-16 days) and 13 days (range, 11-29 days), respectively. Primary platelet engraftment failure was observed in 1 patient (3.7 %). Acute and chronic GVHD observed in 2 (7.4 %) and 3 (11.1 %) patients, respectively. Neutropenic fever was observed in 13 (44.8 %) of patients until the engraftment after allo-HSCT. One patient died due to CMV infections, two died due to septic shock secondary to fungal infection. CONCLUSION: Although there is no prospective data directly comparing BM with PB as stem cell source in AA, observational studies indicates better OS with BM. PB can be used in certain situations such as higher risk for graft failure and donor preference. This study demonstrated that PB-derived stem cell seems to be a reasonable alternative to BM.

RESUMEN

Thrombotic microangiopathy(TMA) is a pathological diagnosis characterized by abnormalities of small vessels leading to microvascular thrombosis of arterioles and capillaries. The current prospective, non-interventional, multicenter (n:18) study aimed to define distribution of different TMA forms in adult Turkish patients who were referred for therapeutic plasma exchange (TPE) for a presumptive diagnosis of TMA. Patients with serum ADAMTS13 activity <5% were diagnosed as acquired thrombotic thrombocytopenic purpura (aTTP). Patients presenting with ADAMTS13 activity 6-10 % / normal renal function and patients with ADAMTS13 activity >10 %, normal renal function and no secondary TMA were treated as unclassified TMA. The study included a total of 97 patients (female: 60; male: 30) with a median age of 48 (18-74). Detailed evaluation at 1 month after hospital admission revealed aTTP, secondary TMA, infection/complement-associated hemolytic uremic syndrome and unclassified TMA in 32 (33 %), 33 (34 %), 26 (27 %) and 6 (6%) patients respectively. As subclassification of various TMAs will dictate specific therapy, proper diagnosis in a timely manner is of utmost clinical significance.

RESUMEN

Background/aim: Graft-versus-host disease (GVHD) is a crucial complication leading to significant morbidity and mortality allogeneic hematopoietic stem cell transplantation which occurs in approximately half of the transplant recipients. Suppression of tumorigenicity 2 (ST2) and regenerating islet-derived 3-alpha(Reg3a) might be important biomarkers to predict acute GVHD. Materials and methods: In the present study, blood samples were collected from 17 patients with acute GVHD and 12 control patients after allogeneic stem cell transplantation. ST2 and Reg3a were measured in plasma samples compared in patients with acute GVHD and the controls. Results: Median age of the study population was 42 years (range 19­49). When compared to controls, the mean ST2 levels was significant higher in acute GVHD (9794 ng/dL vs. 2646 ng/dL, P = 0.008). Mean Reg3a level did not show significant difference between control and acute GVHD group (8848 ng/dL vs. 5632 ng/dL, respectively, P = 0.190). Conclusion: The ST2 level might be used as a significant biomarker for predicting acute GVHD.

RESUMEN

Background/aim: To evaluate the incidence, clinical features, risk factors, and prognosis of central nervous system (CNS) involvement in patients with acute myeloid leukemia (AML). Materials and methods: All AML patients who were admitted to Hacettepe University hospital between 2000 and 2021 were evaluated. The medical records of 548 AML cases were retrospectively analyzed. Results: The frequency of CNS involvement was 2.4% (n = 13) at diagnosis and 4.6% (n = 25) at diagnosis or during follow-up. Parenchymal involvement was seen in 5 patients, leptomeningeal involvement was seen in 11 patients. Three patients had both leptomeningeal and parenchymal involvements, and 6 patients had optic nerve or ocular involvement. In univariate analysis, younger age and extramedullary involvement at diagnosis were associated with CNS disease at diagnosis, and extramedullary involvement at diagnosis was associated with CNS disease during follow-up. In multivariate analysis; younger age and extramedullary involvement at diagnosis were associated with CNS disease at diagnosis and during follow-up respectively. Median overall survival was 5.4 months in patients with CNS disease at diagnosis and 16.9 months in patients with CNS disease during follow-up and 16.2 months in patients with no CNS disease. Conclusion: CNS disease is a rare complication of AML. Younger age and extramedullary involvement at diagnosis are risk factors for CNS involvement.

RESUMEN

Background/aim: Hepatitis B virus (HBV) vaccination rates are insufficient in high-risk patients worldwide. This study aimed to investigate the screening, immunization, and vaccination rates in three high-risk groups for HBV infection: allogeneic hematopoietic stem cell transplantation (AHSCT), renal transplantation (RT), and chronic hepatitis C (CHC) groups. Materials and methods: The serological data of consecutive patients between 2014 and 2019 were reviewed using the hospital database. Results: The HBV screening rates were 100.0%, 90.4%, and 82.4% in the AHSCT, CHC, and RT groups, respectively (p = 0.003). The immunization rates against HBV through either previous exposure or vaccination were 79.5%, 71.7%, and 46.5% in the AHSCT, RT, and CHC groups, respectively (p < 0.001). The HBV vaccination rate was significantly low in the CHC group (71.5%, 69.0%, 34.6% in the AHSCT, RT, and CHC groups, respectively, p < 0.001). If patients lost their immunity due to immunosuppressive therapy were accounted, the vaccination rates increased to 95.2% in the AHSCT group and 72.9% in the RT group. The rate of annual screening for HBV status was 97.9% in the AHSCT group, but it was only 23.9% in the RT group. Conclusion: HBV screening and vaccination rates were significantly lower in the RT and CHC groups than in the AHSCT group.

RESUMEN

Background/aim: The disease caused by SARS-CoV-2 was named as COVID-19. There is as yet insufficient information about the effects of HSCT on the clinical course of COVID-19. In the present study, we aimed to investigate the clinical course of COVID-19 in patients who had undergone HSCT. Materials and methods: We analyzed baseline characteristics, clinical course and findings of COVID-19, hospitalization and death rates, overall survival, and case fatality rates of HSCT recipients diagnosed with COVID-19 retrospectively. Results: 57.6% of the patients underwent AHSCT, and 42.4% underwent allo-HSCT. 60.6%, 27.3%, and 12.1% of the patients had mild, moderate, and severe COVID-19 or critical illness, respectively. Overall, 45.5% were hospitalized, 12.1% required intensive care, and 9.1% necessitated invasive mechanical ventilation. The total CFR was 9.1% in HSCT recipients, 22.2% in patients with active hematologic malignancy, and 4.2% in patients without active hematologic malignancy. Conclusion: It can be concluded that mortality of HSCT recipients is lower in patients whose primary disease is in remission compared to ones that are not in remission. Further studies with larger group patients are needed in order to delineate the effects of COVID-19 on HSCT patients.

RESUMEN

Classical Hodgkin lymphoma (cHL) is considered a curable disease; however, approximately one-third of responders experience disease relapse following first-line therapy. Several studies have shown the efficacy of brentuximab vedotin (BV) in patients with relapsed/refractory HL. We present a retrospective analysis of 58 patients with relapsed/refractory HL treated with BV in a named patient program from 11 centers. The median follow-up duration was 20 (range, 4-84) months. The best overall response rate was 64% (complete response [CR], 31%; partial response [PR], 33%). The 5-year progression-free survival (PFS) and overall survival (OS) rates were 12% (95% confidence interval [CI], 0.05-0.22) and 26% (95% CI, 0.16-0.38), respectively. Among patients who achieved CR, the estimated 5-year PFS and OS rates were 32% (95% CI, 0.13-0.54) and 60% (95% CI, 0.33-0.78), respectively. A total of 26 patients underwent subsequent stem cell transplantation. The 5-year PFS and OS rates for 10 patients who had consolidative stem cell transplantation were 28% and 30%, respectively. Twenty-seven patients required further therapy following BV. At the time of the analysis, 12 patients (21%) were alive. Five patients (9%) had long-term remission after achieving CR with BV monotherapy, with a median PFS of 76 months. Three of them (5%) did not receive any other treatment following BV and their median PFS was 75 months. Our long-term results showed that a small subset of patients with relapsed/refractory cHL may benefit from and even be cured with BV monotherapy.

RESUMEN

PURPOSE: The aim of this study was to determine effectiveness of an individual exercise program by starting before hematopoietic stem cell transplantation (HSCT) and continued with home exercise program after discharge up to 100 days after transplantation. METHODS: Totally, 50 patients were included in this study, and participants were assigned to two groups as intervention group (IG, n = 25) and control group (CG, n = 25). Participants were assessed at three time points: before HSCT, at the discharge, and at the 100th day after HSCT. Functional exercise capacity, physical functions, muscle strength, cognitive functions, quality of life, fatigue, and emotional status of the individuals were assessed. For IG, aerobic, muscle strengthening, endurance, and stretching exercises were performed through hospitalization, and an individual exercise and walking program was advised as home exercise program after discharge. RESULTS: Peripheral muscle strength and quality of life level was higher in IG than CG as a result of inpatient supervised exercise program (p Ë‚ 0.05). At the 100th day, positive effects of the home exercise program on cardiopulmonary exercise capacity, peripheral muscle strength, quality of life, and fatigue level continued when compared with CG (p Ë‚ 0.05). CONCLUSION: As a result of our study, an exercise program continued up to 100 days after HSCT which is individual and partly supervised by a physiotherapist has positive effects on physical functions, clinical status, fatigue, and quality of life level throughout HSCT. Exercise programs for individuals undergoing HSCT should be performed day by day according to the patients' daily clinical and hematologic status and their performance capacity.

RESUMEN

X-linked adrenoleukodystrophy (X-ALD), a progressive neurometabolic disorder that is caused by a defect in the gene ABCD1 (ATP-binding cassette, subfamily D, member 1), which encodes the peroxisomal ABC half-transporter ALD protein. Recently, allogeneic hematopoietic stem cell transplantation (alloHSCT) is the only therapy known to prevent disease progression. In this study, we would like to present our experience of alloHSCT for X-ALD from a HLA matched related sibling by the use of reduced intensity conditioning regimen composed of fludarabine, busulfan and ATG which allows us to reduce procedure-related toxicity and prevent mortality while achieving a curative effect.

RESUMEN

Hematopoietic stem cell transplantation (HSCT) is a highly successful treatment option for many hematological malignancies. Several adverse effects can be seen in HSCT due to the infusion and damage caused by the conditioning regimens. Cardiovascular adverse effects are relatively common during HSCT, and they have the potential to cause devastating complications. The aim of present study was to evaluate the transplantation-related cardiac adverse effects and determine the risk factors in patients undergoing HSCT at our institution. A retrospective analysis has been performed in 662 patients who was treated at Hacettepe University Stem Cell Transplantation Unit. Amongst the 622 patients, 318 (51.1 %) underwent autologous and 304 (48.9 %) underwent allogeneic HSCT. The frequency of the cardiac adverse effects was found to be 10.8 % in all the study population. The most common adverse effect was tachyarrhythmia, constituting 7.9 % of all population. These adverse effects were mostly occurred in lymphoma patients (14 %). Nineteen (3.0 %) of all patients developed atrial fibrillation mostly on the 4th day (range of 1-9 days) after transplantation. Life-threatening events are extremely rare. These adverse effects appear to be related to the type of transplantation rather than the underlying disease. Therefore, close follow-up of patients is important during the peri-transplantation period.
