Apheresis in patients with sepsis: A multicenter retrospective study
(Pergamon-Elsevier Science Ltd, 2021) Aydin, Kaniye; Korkmaz, Serdal; Erkurt, Mehmet Ali; Sarici, Ahmet; Ekinci, Omer; Baysal, Nuran Ahu; Berber, Ilhami
Background and objectives: To consider the effectiveness of apheresis, which is a supportive treatment method, in sepsis. Materials and methods: A hundred and eleven adults with sepsis or septic shock were included in this retrospective study. The demographic characteristics of the patients, the focus and source of infection causing sepsis or septic shock, characteristics of the pathogen, Acute Physiological and Chronic Health Assessment (APACHE) II score, routine laboratory values, which apheresis method was used, the characteristics of the replacement fluids used during the apheresis procedure, the number of apheresis procedures, complications related to the apheresis procedure, the follow-up time after the procedure, and mortality were recorded. The primary outcome was 28day mortality. Results: Sixty-nine (62.2 %) of the patients were male. The mean age of the patients was 47.7 +/- 18.6 years. The most common source of sepsis was hospital-acquired (79.3 %), the most common pathogen causing sepsis was gram-negative bacteria (41.4 %), and the most common infection site was the respiratory tract (58.7 %). The median APACHE II score was 19 (13-24). 92 (82.9 %) of the patients had septic shock. Theropeutic plasma exchange (TPE) was performed in 11.7 % of the patients and immunoabsorbtion IA in 88.3 %. The median number of sessions was 3 (3-5). No procedure-related fatal complication was observed in the study. While 28day mortality was 61.3 % in all patients, when the mortality according to the apheresis procedures was examined, it was 11.3 % and 88.2 % in the patients who underwent TPE and IA, respectively. The most common cause of mortality was multiorgan failure. Conclusions: Apheresis in sepsis can be considered as a salvage treatment. The indication for apheresis in sepsis is still at the level of patient-based individualized decision in line with the studies done so far, including our study. However, there is a need for a multicenter randomized controlled study with a large number of patients in order to give positive or negative recommendations about its effectiveness.

(Int Scientific Information, Inc, 2016) Koroglu, Mustafa; Erkurt, Mehmet Ali; Kuku, Irfan; Kaya, Emin; Berber, Ilhami; Nizam, Ilknur; Yagar, Yavuz
Background: Preventive interventions save lives during the process of chemotherapy for hematologic malignancies, when a hematology laboratory can ensure accurate results. The use of a pneumatic tube system (PTS) is associated with measurement errors and unnecessary transfusions. The aim of this study was to evaluate pre-analytical errors associated with transportation method (PTS versus hand-delivered) and to investigate whether there are unnecessary transfusion events in pancytopenia leukemia patients with very low hematological parameters. Material/Methods: A total of 140 paired blood collections were performed for hemogram and biochemistry assays. Paired EDTA and serum gel blood samples were collected from 58 cases with acute leukemia on different days. For each pair, one sample was hand-delivered by a courier (Group 1) while the other sample was transported through a PTS (Group 2). Results: The hand-delivered method showed that some platelet transfusions were unnecessary for different thrombocyte cut-off values. Calculated unnecessary platelet (PLT) transfusion ratios when using PTS (PLT <30x10(3)/mu L, 16.3%; PLT <25x10(3)/mu L, 16.4%; PLT <20x10(3)/mu L, 80.3%; PLT <15x10(3)/mu L, 48.6%; and PLT <10x10(3)/mu L, 150.0%) were found to be statistically significant (p=0.002, p=0.046, p<0.000, p=0.028, and p<0.000, respectively). In contrast, for RBC transfusion ratios, although the ratios were high in Group 2, we found no significant difference between the two groups; (HGB <8.0 g/dL, 23.3%; HGB <9.0 g/dL, 25.0%, HGB<10.0 g/dL, 19.3%) and (p=0.002, p=0.085, p<0.160, and p=0.235, respectively). Conclusions: Although our results cannot be universally applied, physicians should be careful, skeptical, and suspicious of transfusion decisions in hematology clinics and consider potential analytical and pre-analytical errors in cases of severe cytopenia when using PTS.
Bone Marrow Transplantation as a Rare Cause of Pulmonary Arterial Hypertension
(Kare Publ, 2023) Ulutas, Zeynep; Ermis, Hilal; Ermis, Necip; Berber, Ilhami; Hidayet, Siho
The development of pulmonary arterial hypertension after bone marrow transplantation (BMT) is a rare but serious complication. In this case report, we presented the development of pulmonary arterial hypertension in a 22-year-old woman who underwent BMT due to aplastic anemia. Her symptoms on admission included shortness of breath, palpitations and fatigue. Pulmonary hypertension was classified with right heart catheterization as pul monary arterial hypertension. The patient's laboratory, echocardiographic and hemodynamic findings improved with pulmonary arterial hypertension-specific treatment. Pul monary arterial hypertension should be considered in the differ ential diagnosis of BMT patients with 'unexplained' hypoxemia or respiratory distress.
Can BuCyE conditioning regimen be an alternative treatment to BEAM at autologous transplantation in malignant lymphoma patients?: a single center experience
(E-Century Publishing Corp, 2015) Berber, Ilhami; Erkurt, Mehmet Ali; Nizam, Ilknur; Koroglu, Mustafa; Kaya, Emin; Kuku, Irfan; Bag, Harika Gozukara
High-dose chemotherapy (HDC) applied together with autologous stem cell transplantation (ASCT) is a commonly used treatment modality in patients with malignant lymphoma. At present, there is a limited number of studies which compare toxicity and efficacy of various high-dose regimens applied in the treatment of malignant lymphoma. For this reason, the aim of this study was to investigate the efficacy and toxicity of BuCyE (busulfan, cyclophosphamide and etoposide) and BEAM (carmustine, etoposide, cytarabine and melphalan) preparative regimens in the patients with malignant lymphoma scheduled for autologous stem cell transplantation. Between November, 2010 and April, 2015, 42 patients with relapsed or refractory malignant lymphoma who underwent autologous stem cell transplantation following BEAM (n=11) and BuCyE (n=31) preparative regimens were analyzed at Bone Marrow Transplantation Unit of TurgutOzal Medicine Center in Turkey. The groups were compared in terms of patient characteristics, hematopoietic engraftment time, toxicity profiles and survival. No significant differences were detected between the groups with regard to age, gender distribution, international prognostic index, ASCT indications, disease status at the time of ASCT and type of lymphoma (P>0.05). Median number of infused CD34+ cells/kg, neutrophil and platelet engraftment statuses of BuCyE and BEAM groups were found to be similar (P>0.05). More patients in BuCyE group developed mucositis and nausea, but this difference was not statistically significant (P>0.05). A similar statistically insignificant difference was seen in that infectious complications occurred more commonly in BEAM group (P>0.05). Overall survival and event-free survival rates were not significantly different between the groups (P>0.05). BuCyE is a conditioning regimen which can be effectively used as an alternative to BEAM in the patients with malignant lymphoma undergoing ASCT. Moreover, toxicity rates of both regimens are similar. In order to comprehend the effect of each HDC regimen, further evidence-based data obtained from the studies involving larger sample sizes are required.
Clinical characteristics and therapeutic outcomes of elderly patients with chronic myeloid leukemia: A retrospective multicenter study
(Wiley, 2015) Korkmaz, Serdal; Dal, Mehmet Sinan; Berber, Ilhami; Sahin, Deniz Goren; Dogu, Mehmet Hilmi; Ayyildiz, Orhan; Nizam, Ilknur
AimsWe aimed to investigate whether older age leads to limitations in the starting dose of imatinib in daily treatment of chronic myeloid leukemia, and to determine the compliance of elderly patients with tyrosine kinase inhibitors (TKI) therapy. MethodsData including the clinical characteristics, therapeutic outcomes and compliance with TKI therapy of elderly patients with chronic myeloid leukemia aged >65years were collected from 13 institutions in Turkey, retrospectively. ResultsA total of 69 patients (27 [39%] men, 42 [61%] women) were evaluated retrospectively. The median age of the patients was 71years (range 66-85years). Of the patients, 66 (96%) were in the chronic phase and three (4.3%) were in the accelerated phase when diagnosed. A total of 63 (91.3%) patients were receiving imatinib as the first-line therapy. The initial dose of imatinib was 400mg/day in 59 patients (93.6%). Imatinib treatment induced 57 (90.5%) complete hematological responses at 3months, 29 (46%) complete cytogenetic responses at 6months and 49 (77.7%) major molecular responses at 12months. As a result, nilotinib and dasatinib were used in 14 patients as second-line therapy. Second-line TKI induced nine complete hematological responses (64.3%) at 3months, four complete cytogenetic responses (28.6%) at 12months and seven major molecular responses (50%) at 18months. A total of 56 of the patients (81.2%) are still alive. The median overall survival and progression-free survival rates were 35months (range 1-95months) and 17months (range 0.8-95months), respectively. ConclusionElderly patients should receive TKI according to the same guidelines that apply to younger patients. Geriatr Gerontol Int 2015; 15: 729-735.

CLINICAL CHARACTERISTICS, POST-TREATMENT ASSESSMENT AND PROGNOSTIC FACTORS AFFECTING PATIENT SURVIVAL OF PATIENTS AT 65 YEARS OF AGE OR OLDER WITH HODGKIN LYMPHOMA: A RETROSPECTIVE MULTICENTER STUDY FROM TURKEY
(Carbone Editore, 2015) Berber, Ilhami; Erkurt, Mehmet Ali; Keklik, Muzaffer; Dogu, Mehmet Hilmi; Terzi, Hatice; Pala, Cigdem; Sari, Hakan Ismail
Introduction: During the last three decades, major advances have been made in the therapy of Hodgkin's lymphoma. However, despite these advances, Hodgkin's lymphoma has a poor prognosis in the elderly. The proportion of Hodgkin's lymphoma patients aged > 60 ranges in the different reports between 15% and 35%. This study aimed to examine clinical characteristics, treatment outcomes and prognostic factors affecting patient survival in Hodgkin's lymphoma patients aged 65 years or older. Material methods: Hodgkin's lymphoma patients at 65 years of age and older managed within last 5 years in a total of 5 centers in Turkey were retrospectively assessed. Results: The median age of a total of 32 patients was 71 (65-83) years. Elderly patients presented more frequently with B symptoms, elevated sedimentation rate, mixed cellularity histologic subtype and comorbid disease. Less frequent were bulky disease, bone marrow involvement, and the application of autologous stem cell transplantation. The nodular lymphocyte predominant subtype and lymphocyte rich subtype were not observed at all. Eastern Cooperative Oncology Group, ferritin, total protein, and histological type were significant predictors affecting survival (p<0.05). Conclusions: Hodgkin's lymphoma is a more fatal disease in 65 years of age or older, when compared to the young population. Tumor biology, older age itself, and other factors related to comorbidity probably contribute to the worse outcome of elderly patients. Further large-scale studies are needed to better investigate the factors that were significant predictors of patient survival.

(2021) Sarici, Ahmet; Kaya, Emin; Erkurt, Mehmet Ali; Berber, Ilhami; Tanrıverdi, Lokman Hekim; Bahçecioğlu, Ömer Faruk; Gök, Selim; Kuku, Irfan
Aim: Vincristine-doxorubicin-dexamethasone (VAD) was the commonly used first-line treatment for multiple myeloma (MM) patients with renal failure before bortezomib entered clinical practice. In this trial, we aimed to compare the effect of VAD and bortezomibcyclophosphamide-dexamethasone (VCD) chemotherapy regimens on improving kidney function in MM patients with renal failure. Materials and Methods: The records of MM patients in our center between January 2010 and February 2020 were retrospectively analyzed. Patients who received VAD or VCD as a first treatment chemotherapy protocol and whose initially estimated glomerular filtration rate (eGFR) was 50 mL/min/1.73 m2and below were included in the study. Patients were divided into two groups according to the chemotherapy regimens they received. Results: Sixty one MM patients (VAD: 26, VCD: 35) were included in the study. No significant difference was found between the VAD and VCD groups when the baseline, 1st and 2nd month eGFRs were compared (p>0.05). Overall renal response rate (at least minor response) in the VCD group at the end of the 1st month were higher than in the VAD group (p=0.002). Also, renal response rate in the VCD group at the end of the 2nd month were higher than in the VAD group (p=0.033). Conclusion: In MM patients with renal insufficiency, overall renal response rates have increased with the use of VCD instead of VAD as a standard induction regimen.
Concurrent congenital hemophilia B and acquired hemophilia A: a unique case report
(Lippincott Williams & Wilkins, 2024) Cirik, Salih; Erkurt, Mehmet Ali; Kuku, Irfan; Kaya, Emin; Berber, Ilhami; Hidayet, Emine; Bicim, Soykan
Congenital hemophilia B is a rare X-linked recessive bleeding disorder caused by factor IX deficiency. Acquired hemophilia A is a rare, acquired bleeding disorder that presents with new-onset bleeding, especially in older adults, due to the development of auto-antibodies against factor VIII (FVIII). This case report presents the medical management of a patient with congenital hemophilia B and acquired hemophilia A. We highlight the limitations of maintaining factor levels with factor replacement therapy alone, particularly in hemophilia patients who have developed factor inhibitors. In addition, we draw attention to the need for dose escalation, the cost, and the need for immune-tolerance induction therapy. This case illustrates that when the current diagnosis does not explain the full clinical picture and laboratory data are inadequate, it is important to continue to seek alternative diagnoses and cost-effective treatment.
Convalescent plasma therapy in COVID-19
(2022) Uysal, Ayşe; Erkurt, Mehmet Ali; Kuku, Irfan; Sarici, Ahmet; Bicim, Soykan; Kaya, Emin; Berber, Ilhami
The coronavirus disease 2019 (COVID?19) affected many people in a short time and 5-10% of them were severely affected by the disease. A variety of treatment methods have been developed for this rapidly spreading disease and vaccine studies have been initiated. One of these treatment methods is convalescent plasma (CP) therapy which is a passive immunization therapy. CP method is based on the principle of giving the plasma containing the antibodies formed against the pathogen to people who have active disease after they have recovered from the disease which is a very effective but short-term solution until a definitive and permanent treatment (vaccine, drug, etc.) is found in pandemic conditions. Here, we presented the use of CP in the COVID-19 pandemic.
Convalescent plasma therapy in patients withCOVID-19
(Wiley, 2020) Yigenoglu, Tugce Nur; Hacibekiroglu, Tuba; Berber, Ilhami; Dal, Mehmet Sinan; Basturk, Abdulkadir; Namdaroglu, Sinem; Korkmaz, Serdal
There are currently no licensed vaccines or therapeutics for COVID-19. Anti-SARS CoV-2 antibody-containing plasmas, obtained from the recovered individuals who had confirmed COVID-19, have been started to be collected using apheresis devices and stored in blood banks in some countries in order to administer to the patients with COVID-19 for reducing the need of intensive care and the mortality rates. Therefore, in this review, we aim to point out some important issues related to convalescent plasma (CP) and its use in COVID-19. CP may be an adjunctive treatment option to the anti-viral therapy. The protective effect of CP may continue for weeks and months. After the assessment of the donor, 200-600 mL plasma can be collected with apheresis devices. The donation interval may vary between countries. Even though limited published studies are not prospective or randomized, until the development of vaccines or therapeutics, CP seems to be a safe and probably effective treatment for critically ill patients with COVID-19. It could also be used for prophylactic purposes but the safety and effectiveness of this approach should be tested in randomized prospective clinical trials.
DHAP plus filgrastim as an effective peripheral stem cell mobilization regimen for autologous stem-cell transplantation in patients with relapsed/refractory lymphoma: A single center experience
(Pergamon-Elsevier Science Ltd, 2016) Berber, Ilhami; Erkurt, Mehmet Ali; Kuku, Irfan; Maya, Emin; Bag, Harika Gozukara; Nizam, Ilknur; Koroglu, Mustafa
This study aimed to evaluate the efficiency of DHAP regimen plus filgrastim for mobilization of stem cells in patients with recurrent and/or refractory lymphoma. Thirty-four patients who took DHAP as salvage therapy prior to autologous stem cell transplantation were included. After chemotherapies, 2 cycles of DHAP plus filgrastim were administered to the patients. Stem cells from 32 patients (94%) were collected on median 11th day (8-12), and the median collected CD34(+) cell dose was 9.7 x 10(6)/kg (range 3.8-41.6). DHAP plus filgrastim was found to be an effective chemotherapy regimen in mobilizing CD34(+) stem cells into the peripheral. (c) 2016 Elsevier Ltd. All rights reserved.

(Pergamon-Elsevier Science Ltd, 2023) Uysal, Ayse; Erkurt, Mehmet Ali; Kuku, Irfan; Kaya, Emin; Sarici, Ahmet; Berber, Ilhami; Bicim, Soykan
Background: In this retrospective study, we evaluated the effect of ferritin levels on the outcomes of autologous stem cell transplantation in patients with MM or lymphoma.Methods: In this study, 170 patients with measured ferritin levels within one month before transplantation who underwent ASCT with the diagnosis of MM or lymphoma were evaluated. The cut-off value of ferritin was determined as 500 ng/mL to evaluate the transplant outcomes in both groups. The hematological recovery status/duration, febrile neutropenia rate, hospitalization time, transplant-related mortality (TRM) in the first 100 days, and OS were evaluated according to the ferritin levelResults: Of all patients, 105 (61,8%) were diagnosed with MM and 65 (38.2%) with lymphoma. Ferritin levels had no statistically significant effect on the engraftment status/times, the febrile neutropenia rates, and hospitalization times of both lymphoma and myeloma patients (p > .05). Ferritin level was not significantly associated with TRM in MM (p = .224). However, in lymphoma, ferritin level was significantly associated with TRM (33.3% for ferritin level & GE;500 ng/L vs. 5.3% for ferritin level ng/mL, p = .005). There was no statistically significant correlation between ferritin value and OS in MM group [ferritin level & GE; 500 ng/L: 39.9 months (95% CI: 33.7-46.1) and ferritin level 500 ng/mL: 39.4 months (95% CI: 36.5-42.2), p = .446]. Ferritin level was significantly associated with OS in patients with lymphoma [ferritin level & GE; 500 ng/L: 22.1 months 95% CI: 14.7-29.5), ferritin level 500 ng/mL: 27.3 months (95% CI: 22.4-32.2), p = .038]Conclusion: High ferritin level is important prognostic factor on survival after ASCT in patients with lymphoma.
Does the preference of peripheral versus central venous access in peripheral blood stem cell collection/yield change stem cell kinetics in autologous stem cell transplantation?
(Pergamon-Elsevier Science Ltd, 2016) Dogu, Mehmet Hilmi; Kaya, Ali Hakan; Berber, Ilhami; Sari, Ismail; Tekgunduz, Emre; Erkurt, Mehmet Ali; Iskender, Dicle
Central venous access is often used during apheresis procedure in stem cell collection. The aim of the present study was to evaluate whether central or peripheral venous access has an effect on stem cell yield and the kinetics of the procedure and the product in patients undergoing ASCT after high dose therapy. A total of 327 patients were retrospectively reviewed. The use of peripheral venous access for stem cell yield was significantly more frequent in males compared to females (p = 0.005). Total volume of the product was significantly lower in central venous access group (p = 0.046). As being a less invasive procedure, peripheral venous access can be used for stem cell yield in eligible selected patients. (c) 2016 Elsevier Ltd. All rights reserved.

(2019) Oksuz, Ersoy; Bugday, Muhammet Serdar; Soyalp, Celaleddin; Karaaslan, Erol; Oto, Gokhan; Temelli Goceroglu, Rezzan; Berber, Ilhami
Aim: Drug-drug interactions (DDIs) are an important factor that can lead to serious health problems by increasing or decreasing the effects of drugs. This study aimed to evaluate the frequency of DDIs in the intensive care unit (ICU).Material and Methods: All patients who were hospitalized for more than 24 h in the ICU of our hospital between January and September 2018 and received 2 or more medications were included in this retrospective study. Frequency and severity of the DDIs were detected using the Rx Mediapharma and Lexi-Interact programs.Results: Of the 972 patients enrolled in the study, 2742 incidences of DDIs were detected in 626 patients (64%). Of the different drug pairs administered, 422 had DDIs, and 64 of those had 10 or more DDIs, constituting 67% of all of the DDIs. The most common potential clinical consequences of DDIs were increased risk of bleeding (12.3%), hyperkalemia (8.2%), arrhythmia (7.9%), and CNS depression (6.6%). Conclusion: The results indicated that DDIs in the ICU were very common in our hospital. Moreover, these results indicated that patients should be closely monitored for the prevention of adverse effects, such as electrolyte disturbance, bleeding risk, and arrhythmia of drugs.
Early therapeutic plasma exchange may improve treatment outcomes in severe acute toxic Hepatitis
(Pergamon-Elsevier Science Ltd, 2021) Berber, Ilhami; Cagin, Yasir Furkan; Erdogan, Mehmet Ali; Ataman, Engin; Gozukara, Harika; Erkurt, Mehmet Ali; Yildirim, Oguzhan
Background and objectives: Acute toxic hepatitis can result in a different clinical course from a completely curable disease to subacute hepatitis, chronic hepatitis, and fulminant hepatitis failure, which is quite mortal. For this purpose, therapeutic plasma exchange (TPE) can be used for improving treatment outcomes by reducing the harmful substances caused with and/or without liver function in acute toxic hepatitis. We aimed to evaluate treatment outcomes in severe acute toxic hepatitis patients who applied early TPE procedure. Materials and Methods: A total of 335 patients who received TPE between 2010-2021 were retrospectively screened and 59 (male/female, 30/29; min/max-age, 22-84) patients with acute toxic hepatitis who underwent TPE in the first 24 h were included in the study. TPE was performed in patients who had high total bilirubin level (>10 mg/dL). Laboratory parameters of the patients before and after the TPE procedure, number of patients developed complications of acute toxic hepatitis and mortality rates were evaluated for effectiveness of TPE. Results: Acute toxic hepatitis was associated with hepatotoxic drugs in 44 (74.5 %), herbal medication 6 (10.2 %), mushroom poisoning 6 (10.2 %) and with substance abuse 3 (5.1 %) in patients. When the patients were compared based on INR, liver function tests, ammonia, lactate and Model For End-Stage Liver Disease (MELD) score at baseline, 48 h after TPE (independently of TPE number) and before final state a statistically significant decrease was observed in all parameters (p < 0.05). Fifty three (90 %) of patients improved without complications, the remaining 6 (10 %) patients were diagnosed with fulminant hepatitis. All these remaining patients died before liver transplantation (LTx) could be performed. Conclusion: TPE is a safe, tolerable therapy option and early TPE may improve treatment outcomes in severe acute toxic hepatitis.
The effect of comorbidity on survival and collected CD34+cell counts in autologous hematopoietic stem cell transplant patients
(Pergamon-Elsevier Science Ltd, 2022) Sarici, Ahmet; Erkurt, Mehmet Ali; Kuku, Irfan; Bahcecioglu, Omer Faruk; Bicim, Soykan; Kaya, Emin; Berber, Ilhami
Objective: In this study, we aimed to report the effectiveness of hematopoietic cell transplantation-specific comorbidity index (HCT-CI) and GATMO scores in predicting overall survival (OS) who underwent autologous stem cell transplantation (ASCT). Material and methods: The data of 263 MM and 204 lymphoma patients who underwent ASCT in the last 11 years were retrospectively analyzed. Results: Neutrophil engraftment time, thrombocyte engraftment time and collected CD34+ cell counts were similar in MM patients with HCT-CI 2 (all p 2 tended to be higher than those with HCT-CI 2 was 51.5 months, the estimated median OS of patients with HCT-CI 2 was 9.5 months (p=0.012). When lymphoma patients were divided into four groups according to their GATMO scores, the OS of the four groups was found to be different from each other (p<0.001). Conclusion: HCT-CI and GATMO scores predict OS in lymphoma patients but not MM patients.
The effect of cryopreserved and noncryopreserved stem cells on the outcome of autologous stem-cell transplantation in multiple myeloma patients: A single-center experience
(Wolters Kluwer Medknow Publications, 2022) Uysal, Ayse; Erkurt, Mehmet A.; Kuku, Irfan; Kaya, Emin; Berber, Ilhami; Sarici, Ahmet; Bicim, Soykan
Background The CD34+ stem cells are either noncryopreserved (non-CP) or cryopreserved (CP) in autologous stem-cell transplantation (ASCT). Some retrospective studies have shown that engraftment failure and engraftment rate are similar in CP cells and infusion reactions are lower in CP cells due to the absence of dimethyl sulfoxide. Objective In this study, we presented our clinical experience comparing the outcomes and safety of ASCT with CP and non-CP stem cells. Patients and methods A total of 163 patients were enrolled between January 2019 and June 2021. Duration of neutrophil/platelet engraftment, rates of infusion-related reactions, febrile neutropenia, and duration of hospitalization were compared between the CP and non-CP groups. Results Fifty five (33.7%) received CP cells, 108 (66.3%) received non-CP cells. The median dose of CD34+ cells was similar in both groups (P=0.755). The median duration of neutrophil and platelet engraftment was not statistically significantly different in CP and non-CP groups (P=0.896 and 0.183, respectively). No statistical difference was observed in the median duration of hospitalization between the two groups [CP: 16 (13-26) vs. non-CP: 15 (11-31) days, P=0.124]. The febrile neutropenia rate was higher in the CP group, but there was no statistical difference between the two groups (CP: 56.4% vs. non-CP, 48.1%, P=0.301). The rates of infusion-related reaction such as nausea, vomiting, and rash were higher in the CP group (21.8 vs. 12%), with no statistically significant difference (P=0.159). Conclusion Non-CP cells have similar outcomes to CP cells and lower toxicity than CP cells, which are safe and effective in ASCT.
Effect of extracorporeal photopheresis on survival in acute graft versus host disease
(Wiley, 2023) Kaya, Ahmet; Erkurt, Mehmet Ali; Kuku, Irfan; Kaya, Emin; Berber, Ilhami; Bicim, Soykan; Hidayet, Emine
Background: Extracorporeal photopheresis (ECP) is the main non-pharmacological approach accompanying systemic medical treatments in steroid-resistant acute or chronic graft versus host disease. The study aimed to examine the effect of ECP on survival in acute graft versus host disease (aGVHD).Methods: A total of 35 patients who were followed up in the adult hematology clinic of Inonu University Turgut ozal Medical Center for aGVHD were included in the study. Stem cell transplantation and ECP application parameters that may affect the survival of the patients were examined.Results: In aGVHD using ECP, the degree of involvement affects survival. Involvements with a clinical and laboratory score (Glucksberg system) of 2 and above significantly reduced survival. The duration of ECP use is associated with survival. Especially, 45 days and longer use increases survival (hazard ratio, P-value <.05). The duration of steroid use was found to be effective in survival in aGVHD (P < .001). ECP administration day (P = .003), duration of steroid use (P < .001), duration of ECP use (P = .001), and grade of aGVHD (P < .001) affect survival.Conclusion: ECP use is effective in survival in patients with aGVHD score =2. In patients with aGVHD, especially the use of 45 days and longer has a positive effect on survival. The duration of steroid use is associated with survival in aGVHD.
