    Abstract Introduction: Graft-versus-host disease (GVHD) is a common complication of allogeneic hematopoietic cell transplantation (HCT). In the treatment of chronic GVHD, skin directed therapy, systemic corticosteroids, calcineurin inhibitors (such as cyclosporine (CsA) and tacrolimus), rituximab, mycophenolate mofetil (MMF), extracorporeal photopheresis (ECP) and ruxolitinib are used.
    Case report: We present an 18 year old male with Philadelphia chromosome positive acute B lymphoblastic leukemia, treated with allogeneic HCT from a full matched sibling donor. The patient had grade 2 chronic cutaneous GVHD resistant to corticosteroids, CsA, MMF, and ECP treatment. Three months after initiation of ruxolitinib therapy, the patient developed skin ulcers on his lower extremities.
    Management & outcome: The biopsy revealed that the changes were caused by the drug reactions. We suspected ruxolitinib as the likely cause of these ulcerative lesions after evaluating the adverse drug reaction probability scale. The adverse drug score was 4, therefore, ruxolitinib treatment was discontinued. Ulcerative lesions fully recovered after 4 weeks of follow-up.
    Discussion: Ruxolitinib is used in the treatment of chronic GVHD that has been resistant to steroids and other salvage therapies. In our case, ruxolitinib was used as a salvage therapy in a patient who had refractory chronic skin GVHD. Ruxolitinib-related skin lesions with ulcers of lower extremities and whole body erythematous skin lesions were reported previously in patients with myelofibrosis. The pathophysiology of ruxolitinib related skin ulcers is unknown. Skin changes of patients using ruxolitinib should be closely monitored, and newly developing lesions should be suspected of being drug-related and biopsied.

    Abstract Introduction: The most common kind of leukemia in adults is chronic lymphocytic leukemia (CLL). CLL is treated with ibrutinib. During the course of ibrutinib therapy, bleeding and cardiac arrhythmias may occur. Non-hemorrhagic adverse events are extremely infrequent in individuals using ibrutinib.
    Case report: A 64 year-old man was diagnosed with CLL in June 2016. He was treated with 6 courses of FCR, he stayed in remission for 3 years and then relapsed. He achieved partial remission after two months of therapy with ibrutinib. The patient was admitted to the hospital with fever and shortness of breath. Pericardial tamponade and effusion was diagnosed during his evaluation.
    Management & outcome: Non-hemorrhagic exudative effusion was drained by pericardiocentesis and a pericardial catheter was inserted to drain pericardial effusion. In all pleural and pericardial effusion samples, pathological and flow cytometric examination revealed no atypical malignant cells for malignancy, including CLL. Infections, both bacterial and viral, were also undetectable in the samples, as were rheumatological markers of collagen vascular disease. Ibrutinib therapy was discontinued. The pericardial effusion and tamponade were linked to ibrutinib treatment after evaluating the adverse drug reaction probability scale with a total score of 6. Colchicine was administered to reduce the pericardial effusion. The catheter was removed; pericardial effusion did not reoccur during follow up visits.
    Discussion: Serious adverse events of ibrutinib are seen when treating CLL patients. This group of individuals should be closely monitored for potentially serious complications such as pericardial effusion and cardiac tamponade.

    Abstract Background: Erdheim Chester disease (ECD) is a rare disease with multisystemic involvement in the group of non-langerhans cell histiocytosis. Although nearly 100 years have passed since its definition, the number of cases reported all over the world is below 1000. In addition to the rarity of the disease, low awareness seems to play a role in this.
    Case presentation: 47-year-old white caucasian women patient who presented to our clinic with symptoms of weakness-fatigue as well as increasing pain in the knees and ptosis in the left eye. Result of the patient's bone biopsy, ECD was considered pathologically and BRAF V600E mutation was shown molecularly. After presenting the clinical, laboratory and other examination results of the case, the dramatic response seen with targeted therapy will be discussed.
    Conclusions: BRAF V600E mutation is frequently seen in ECD. Vemurafenib plays an active role in targeted therapy.

    Abstract Introduction: The prevention of mortality and morbidity related to the increasingly used allogeneic hematopoietic cell transplantation (allo-HCT), along with the effects of pre- and post-transplant immune status on transplant outcomes, have become the focus of the studies conducted on this subject in recent years. In parallel, this study was designed to investigate the effects of pre-conditioning immunoglobulin (pre-conditioning-Ig) and pre-conditioning absolute lymphocyte count (pre-conditioning-ALC) levels on transplant outcomes.
    Methods: This study was designed as a retrospective, observational and cross-sectional study. The objective of the study is to investigate the effects of pre-conditioning-Ig and ALC levels primarily on the rate of patients with febrile neutropenia (FEN) and the duration of FEN and length of hospital stay (LoS), and secondarily on acute graft-versus-host disease (aGVHD), cytomegalovirus (CMV) viremia, and mortality in the acute leukemia patients who underwent allo-HCT.
    Results: A total of 104 acute leukemia patients, of whom 55 had acute lymphoblastic leukemia (ALL) and 49 had acute myeloid leukemia (AML), were included in the study. Compared to the AML group, the median pre-conditioning-IgG, IgA, and IgM levels were found to be significantly lower in the ALL group (11.3 vs. 6.6, p < 0.001; 1.8 vs. 0.9, p < 0.001; and 0.7 vs. 0.4, p < 0.001; respectively). But, there was no significant difference between the groups in pre-conditioning-Ig and ALC levels and transplant outcomes. However, subgroup analysis revealed that high pre-conditioning-ALC levels were significantly correlated with aGVHD levels (Odds Ratio: 1.02; p = 0.034) and low pre-conditioning-IgM levels were significantly correlated with increased mortality rate (Hazard Ratio: 0.08; p = 0.042) in AML patients.
    Conclusion: The significant difference determined between the ALL and AML groups in pre-conditioning-Ig levels was not reflected on the effects of pre-conditioning-Ig and ALC levels on transplant outcomes. However, we observed that pre-conditioning-IgM and ALC levels have an impact on transplant outcomes in AML patients.

    Abstract Çin Halk Cumhuriyeti’nin Wuhan Eyaletinde yarasadan insana bulaş yolu ile tesbit edilen coronavirüs ailesinden Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) virüsü çok hızlı bir yayılım göstererek çok kısa bir sürede tüm dünyada etkisini göstermiştir. 11 Şubat 2020 tarihinde bu virüsün yol açtığı hastalığı COVİD-19 olarak adlandıran Dünya Sağlık Örgütü (WHO) 11 Mart 2020 tarihinde bu salgın hastalığı pandemi olarak ilan etmiştir. Konvelesan plazma (KP) tedavisi tarihteki salgın hastalık dönemlerinde kullanılmış, etkili olduğu gösterilmiş bir pasif antikor tedavisidir. Konvelesan plazmanın etki mekanizmaları arasında virüsü direkt bağlayarak nötrolize etmek, kompleman aktivasyonu, antikor bağımlı sellüler sitotoksisite ve/veya fagositoz yollarıyla virüs eliminasyonunu başlatmak sayılabilir. Nötralizan antikorlar bu etki mekanizmalarında çok önemlidir. Virüsü inaktive ederek viral replikasyonu engellemesi iyileşmedeki en önemli noktadır. Bu yüzden KP da nötrolizan antikor titresi ölçümü önemlidir. Nötralizan olmayan antikorların viral replikasyonu durdurmadığı in vitro olarak gösterilmiş ve bu antikorların proflakside kullanılabileceği, iyileşmede destekleyici etkileri olduğu öne sürülmüştür. COVİD-19 hastalığında yapılan çalışmalarda da KP nın etkili olduğu görülmüştür. Ülkemizde ve Amerikada yakın zamanda tedavi endikasyonu alan bu tedavi yönteminin uygulama kriterleri her iki ülke tarafından belirlenmiştir. Uygun donorlerden, fayda görebilecek hastalara nakledilen konvelesan plazma tedavi sonuçları merakla beklenmektedir.

    Abstract This research is to investigate the parameters which may affect the mobilization of stem cells in patients receiving autologous hematopoietic peripheral blood stem cell transplantation (PBSCT). A retrospective study was carried out using the data derived from the medical files of 242 patients who received PBSCT. Descriptive, clinical, and laboratory parameters were compared between patients with successful and unsuccessful stem cell mobilization. Successful stem cell mobilization ratio was 4.463 times higher when preemptive plerixafor was administrated; 1.032 times higher when CD34+ cell count increased 1 unit at the beginning of mobilization. The white blood cell count was inversely correlated with the success of mobilization. An increase of 1 unit in WBC count was associated with a 1.027 times decrease in the success rate. The data indicated that the administration of preemptive plerixafor and CD34+ cell count at the beginning of mobilization were directly related to the success of mobilization after PBSCT. On contrary, WBC count was inversely associated with the success rate.

    Abstract The activation of the innate and adaptive immune systems by SARS-CoV-2 causes the release of several inflammatory cytokines, including IL-6. The inflammatory hypercytokinemia causes immunopathological changes in the lungs including vascular leakage, and alveolar edema. As a result of these changes in the lungs, hypoxia and acute respiratory distress syndrome occur in patients with COVID-19. Even though there are clinical trials on the development of therapeutics and vaccines, there are currently no licensed vaccines or therapeutics for COVID-19. Pharmacological approaches have shown poor results in sepsis-like syndromes caused by the hypercytokinemia. Suppressing the cytokine storm is an important way to prevent the organ damage in patients with COVID-19. Extracorporeal blood purification could be proposed as an adjunctive therapy for sepsis, aiming to control the associated dysregulation of the immune system, which is known to protect organ functions. Several extracorporeal blood purification therapies are now available, and most of them target endotoxins and/or the cytokines and aim improving the immune response. For this purpose, plasmapheresis and immunoadsorption may be an important adjunctive treatment option to manage the complications caused by cytokine storm in critically ill patients with COVID-19.
