      Acute lymphoblastic leukaemia (ALL) is the most common paediatric malignancy. Despite the fact that the outcome of treatment of ALL in children has improved in the last decades, still as many as 20% of children will undergo treatment failure. Over the last years, there have been great efforts to characterize the genetic alterations of leukaemic cells, which could affect the clinical course of the disease and become new markers that may be targeted with novel therapies. Genomic profiling and sequencing studies have not only identified new subtypes of ALL (e.g. Philadelphia chromosome-like ALL, early T-cell precursor ALL) but also helped to understand the genetic basis of leukaemogenesis and predict treatment failure. Those efforts contributed not only to better risk stratification of children with ALL, but also to development of new tailored therapeutic strategies. So far, improvements in survival of children with Ph+ ALL (Philadelphia positive ALL) have been demonstrated due to combination of intensive chemotherapy with tyrosine kinase (TK) inhibitor (imatinib). There are also some pre- and clinical testing of other inhibitors (TK, FLT3, PI3K/mTOR, MEK) and specific antibodies (CD19 and CD22). Widespread use of modern diagnostic techniques at the early stage of the disease would enable rapid identification of children with a high-risk leukaemia and use of more intensive and tailored therapy.

      Acute myeloid leukemia (AML) is the most common cancer of white blood cells in adults. Men over 65 years old are more prone to develop this disease. Symptoms that lead patients to visit the doctor are: high fever, bone pain, weakness and signs of infection. The etiology of AML is not yet fully understood. The predisposing factors for acute myeloid leukemia may include environmental and genetic factors. If left untreated, it can lead to death within a few weeks. Therefore, it is important to quickly identify the disease and to implement appropriate treatment, which will allow to increase the percentage of survival among patients. The basis of AML diagnosis is the presence of more than 20% of blasts in blood or bone marrow smears. The choice of AML treatment depends on prognostic factors: patients’ age and sex and cytogenetic-molecular risk. The treatment regimen for AML is outdated and remains almost unchanged for over 30 years. Understanding the molecular basis of this disease development and pathomechanism allows to search for new effective treatments, often based on targeted therapies. This article presents contemporary standards of AML diagnosis and the latest trends in its treatment.

      We have performed detailed analysis of the genomic landscape of commercially available K562 cells, employing targeted enrichment of nearly 1300 cancer-related genes followed by next-generation sequencing (NGS) and also classical cytogenetics. Deep sequencing revealed 88 variants of potentially biological significance. Among them we have detected alterations in genes already known to be mutated in K562, such as TP53 but also in several other genes, which are implicated in tumorigenesis and drug resistance, such as MLH1, ASXL1 and BRCA1 as the most prominent examples. Fluorescence in situ hybridization (FISH) of interphases of K562 cells revealed multiplication of the BCR and ABL1 gene copies, as well as the amplification of the BCR-ABL1 fusion gene. Our results may help to better understand genomic instability of the blastic phase of CML represented by the K562 cell line and can help researchers who want to employ this cell line in various experimental settings.

      Medulloblastoma is the most frequent malignant tumor of the central nervous system (CNS) in children, but it can rarely occur in adults. Extraneural relapse of medulloblastoma occurs very rarely and it is usually associated with dismal prognosis. We present a case of young adult with relapsed medulloblastoma with extraneural metastases in the bone marrow and expression of terminal deoxynucleotidyl transferase (TdT) on the malignant cells mimicking acute leukemia. To the best of our knowledge, this is the first report of medulloblastoma exhibiting expression of the TdT in adult. We would like to emphasize that in cases like this, differential diagnosis of anemia and thrombocytopenia in adults should include a consideration of primary or secondary bone marrow involvement by medulloblastoma or other rare malignancy.

      Progressive multifocal leukoencephalopathy (PML) is a disease of immunocompromised patients caused by reactivation of the John Cunningham polyomavirus (JCV). A monoclonal anti-CD20 antibody rituximab is widely used as an important part of therapy for B-cell non-Hodgkin lymphomas and various autoimmune diseases. It is not fully explained how rituximab reactivates JCV. In this report, we present the case of a 61-year-old man with T-cell/histiocyte-rich large B-cell lymphoma who was treated with R-CHOP and intrathecal methotrexate. Two weeks after the first R-CHOP course he developed dysarthria, diplopia, and disturbances in motor coordination. Based on CT/MRI results showing 3cm×2cm large hypodense white matter lesion in left cerebellar hemisphere, and detection of JCV in the cerebrospinal fluid (14300viral copies/mL), the patient was diagnosed with PML. Despite treatment attempt with cidofovir and IVIG, the patient's neurological status continued to worsen. He developed progressive motor neuron deficits but retained intact cognitive functions. The patient deceased nearly three months after onset of rituximab treatment. Rituximab is a milestone in treatment of many hematological and autoimmune diseases. Considering how widespread has the use of rituximab become, the overall risk of developing PML is relatively low. Nevertheless, since the end of 1990s several reports were published on PML development in association with usage of rituximab. The authors would like to emphasize that although the total risk of PML occurrence in patients treated with rituximab is low, it is important that physicians administrating rituximab therapy are aware of this serious complication.

      The goal of this report is to describe a case of knee arthroplasty in a patient with over a 20 year long history of ankylosis of the left knee joint in the course of severe haemophilia A. Clinical and functional conditions were assessed by means of a Knee Society Score (KSS); pain intensity by Visual Analogue Scale (VAS); and intensity of degeneration of bone forming the joint by means of the Kellgren-Lawrence Scale. ROM of the knee joint before and after the operation was measured. We used hinge prosthesis of S-ROM by De Puy to restore the knee joint. As a result of the operation we got axial alignment of the limb. During two years of clinical follow-up, the patient achieved increasing mobility of the operated knee, full extension, and 80 degrees of active flexion. There were no radiological signs of loosening of the implant. The patients’ functional capabilities improved significantly; and pain occurred only occasionally.

      Flow cytometry (FC) has been primarily applied to the diagnosis of hematological malignancies, and thereafter, to detection and quantification of CD34+ cells in bone marrow transplants, and granulocytes in neutropenias and paroxysmal nocturnal hemoglobinuria (PNH). In PNH and hereditary spherocytosis, changes in some of the erythrocyte membrane proteins are tested (CD59, CD55, and band 3). The purpose of this paper is to focus on the use of FC in RBC testing. With anti-D, -HbF, and -CA (carbonic anhydrase), we can detect RhD+, HbF+, and CA- fetal RBCs in the maternal RhD-, HbF-, and CA+ blood sample. Obtained results allow to select the appropriate dose of anti-D Ig in the RhD prophylaxis of feto-maternal incompatibility, or to detect the cause of fetal anemia. Expression of antigens and their weak variants, and concentration of specific antibodies, can also be assessed. It is possible to observe changes in selected CD molecules during storage of RBC units. If RBCs for transfusion are unavailable, due to patient's unusual antibody specificity, some of the available RBCs are opsonised, and then phagocytosis with the recipient monocytes is assessed. The microscopic time-consuming and subjective assay is usually used. Stained CD14+ monocytes and CD235a+ erythrocytes are visible on cytograms as well as their interaction. It makes evaluation of phagocytosis easier and objective. Microparticles of RBCs released during storage are also detected. They are 235a+. In differentiation of hemolysis causes, it is important to measure osmotic fragility, and that can be also achieved using FC. Flow cytometry should be applied to immunohematological testing of red blood cells more often than now.

      Multiple myeloma accounting for 10% of malignancies of haematopoietic system is a heterogenous disease. In the era of individual approach to the patient, we are more and more interested in distinct features and forms of this malignancy. In the article, we described rare MM manifestations with reference to location (central nervous system and skin), M-protein produced by the tumor cells (biclonal and immunoglobulin M), early onset of the disease (young versus old) and pregnancy in MM patients.

      Background: Hemophagocytic lymphohistiocytosis (HLH) is a life-threatening disorder of immune regulation. In patients over 60 years of age, HLH associated with hematological malignancies (hM-HLH) is the most prevalent. β-2-Microglobulin (B2M) plays an important role in antigen presentation and immunological regulation. Elevated B2M levels reflect T-cell activation. Objective: The aim of this study was to determine serum B2M concentrations in adults with hM-HLH and to interpret its significance in the context of overall survival (OS). Patients and methods: Serum B2M concentration was determined in 31 adults aged 22–84 years at the time of hM-HLH diagnosis. Lymphoid malignancy was diagnosed in 22 patients and myeloid malignancy in 9 patients. Results: The serum concentration of B2M was elevated in 100% of the examined patients. Mean and median serum B2M concentrations were 5.3 and 4.2mg/L, respectively (range 2–17mg/L). We have not found any significant differences in terms of the studied serum B2M concentrations between patients with T/NK-cell lymphomas, B-cell lymphomas, and myeloid malignancies. The outcome of HLH was poor in vast majority of patients with the median OS for the entire group of 46 days. Conclusions: Elevated serum B2M level is a frequent finding at the time of hM-HLH diagnosis in adults. It seems to be a useful indicator of HLH for its early detection and evaluation afterward, as well as for immediate therapeutic intervention. Further prospective studies answering the question whether serum B2M can be used as a prognostic factor in hM-HLH would be of interest.

      Rare diseases are a diagnostic challenge for modern medicine. Gaucher disease is a rare autosomal recessive lipid storage disorder caused by the deficient activity of the lysosomal enzyme glucocerebrosidase. In the absence of known affected family member, frequent symptoms of Gaucher disease, such as thrombocytopenia or splenomegaly, often lead to hematological diagnostic workup. This review highlights pathophysiology, signs and symptoms, diagnostic and therapeutic principles of Gaucher disease. Difficulties in diagnosis of Gaucher disease depends mainly on its rarity, but there is also the lack of awareness and limited knowledge about this disease. Basic knowledge of Gaucher disease should be familiar to all physicians, including hematologists.

      Blood transfusion in Poland is the safest in history. High virological level of safety has been achieved mainly by improving not only the qualification of donors and methods used for donor screening, but also applying leukoreduction, pathogen reduction technology and grace period for serum. In this article, we discuss the improvement of the epidemic situation among blood donors for hepatitis B virus (HBV) and hepatitis C virus (HCV) and the increasing trend for HIV. Preliminary results of residual risk calculation for these pathogens are presented. Hepatitis E virus (HEV) and Babesia microti were considered as new factors potentially relevant for the safety of blood transfusion in our country. Due to evidence of West Nile virus (WNV) circulation in the ecosystem in Poland, it is also necessary to monitor the infections with this pathogen. In this article, it was emphasized that the reporting of all possible complications associated with transfusion and meticulous implementation of the look-back procedure play a key role for monitoring the risk of transmission of infectious agents by blood. It is especially important in view of the increasing epidemiological problems associated with emerging infectious agents.

      Ixazomib is a new agent registered in combination with lenalidomide and dexamethasone for the treatment of adult patients with multiple myeloma who have received at least one prior therapy. The drug is the first oral proteasome inhibitor. Registration data show improvement in progression-free survival time (20.6 vs 14.7 months, p=0.01) but recent analysis in Asian population also in overall survival (25.8 vs 15.8 months, HR=0.419, p=0.001) what placed with lack of ixazomib incremental toxicity may implicate clinical importance of the treatment in relapsed or refractory multiple myeloma. Oral dosing of the triplet regimen may decrease the number and duration of hospitalizations that allows for better social functioning and occupational performance, and thus impacts daily disease perception.

      Despite significant progress in the treatment of multiple myeloma, it still remains an incurable disease. The introduction of new drugs has contributed to the increased overall survival of patients diagnosed with multiple myeloma and significantly improved their quality of life. Proteasome inhibitors, immunomodulators and monoclonal antibodies are often used in combination with chemotherapeutic agents. Despite the indisputable role of the new drugs for the treatment of myeloma, high-dose chemotherapy with autologous stem cell transplantation is still the method of choice in a group of younger patients without significant comorbidities. Induction treatment in myeloma patients eligible for autologous stem cell transplantation is particularly important, because the results of the first-line therapy impact further outcome of patients. The quality of the response to first-line treatment determines the progression-free survival. The choice of bortezomib, thalidomide, dexamethasone regimen as induction therapy, recommended by the Polish Myeloma Group, is in line with the recommendations of international experts. The results of the randomized clinical trials have demonstrated that the triple therapy, based on proteasom inhibitors, immunomodulators and steroids, is more effective than regimens involving two drugs only (proteasom inhibitors and steroids or immunomodulators and steroids). Sometimes, due to the clinical situation of the patient and/or unusual features of the disease, it is necessary to individualize induction therapy. The following article provides an overview of different induction regimens for myeloma patients in Poland and suggestions for modifications in justified cases.

      New drugs introduced in recent years to the therapy of multiple myeloma patients resulted in better responses and prolongation of overall survival. While therapeutic regimens based on bortezomib and thalidomide are recommended to most patients in first line therapy, lenalidomide represents the cornerstone for treatment of relapsed/refractory myeloma patients. Most patients profit from prolonged treatment composed of consolidation and maintenance treatment till progression. Besides the concept of longer treatment, it is recommended to start therapy in some patients earlier, taking into consideration biomarkers of active disease. In this article, we described therapeutic recommendation also for Waldenström macroglobulinemia and other plasmacytic dyscrasias.

      Introduction: Metastases of solid tumors to the bone marrow are rarely reported. Clinical manifestation and laboratory findings remain uncharacteristic and lead to misdiagnosis. Detection of bone marrow metastases may have an impact on therapeutic decisions and is usually associated with poor prognosis. Aim: To characterize clinical picture and hematological findings in patients with bone marrow metastasis. Material and methods: We retrospectively reviewed medical records of patients with bone marrow metastases who were primary misdiagnosed with hematological malignancies. Results: Ten patients at median age of 51 years at diagnosis were included. There were following findings on admission: duopenia (n =7), pancytopenia (n =1), anemia (n =1) and skeletal lytic lesions (n =1). The diagnosis of prior cancer was reported in 3 patients and included multiple myeloma, breast cancer and oligoastrocytoma. Clinical manifestations were hepatomegaly (n =4), lymphadenopathy (n =4), skin pallor (n =3), cachexia (n =2) and hemorrhagic diathesis (n =2). Imaging studies revealed diffuse bone lesions (n =5), pulmonary infiltrates (n =2) and liver masses (n =2). Leukoerythroblastosis was demonstrated in 4 cases. Bone marrow aspirate detected the presence of abnormal cell population in 4 patients. In all studied patients a final diagnosis was established by immunohistochemistry of bone marrow biopsy. The following malignancies were detected: prostate adenocarcinoma (n =2), anaplastic microcellular carcinoma of unknown origin (n =2), adenocarcinoma of unknown origin (n =2), Ewing's sarcoma (n =1), breast cancer (n =1), clarocellular renal cancer (n =1) and neuroendocrine tumor (n =1). Nine out of the 10 metastatic patients died shortly after chemotherapy. Conclusions: Unexplained hematological abnormalities should arise the suspicion of bone marrow metastases.

      Primary extranodal location of Hodgkin lymphoma is uncommon. We present a case of a 43-year old man with isolated Hodgkin disease localized in the nasopharynx who presented with a complaint of bilateral nasal congestion. Primary location of Hodgkin lymphoma (HL) in the non-lymphoid tissue is very uncommon and the primary isolated involvement of the nasopharynx has been described in 35 cases in the worldwide literature.

      Haemate P is a plasma-derived concentrate used in the treatment of von Willebrand disease and haemophilia A. In comparison with other concentrates, this product is characterised by a high content of high-molecular-weight multimers. The ratio of von Willebrand factor (vWF:RCo) to factor VIII (FVIII) is 2.4:1. Haemate P is used with a high efficacy and safety when desmopressin (DDAVP) is ineffective or contraindicated, in all forms of von Willebrand disease (vWD), in the treatment of bleeding, in preparation for surgery and in prophylaxis in some patients, especially those with type 3 of the disease. The favourable vWF:RCo/FVIII ratio prevents accumulation of FVIII and related thromboembolic complications. Haemate P has been considered a gold standard in the treatment of von Willebrand disease for many years. This concentrate is used also in haemophilia A replacement therapy. One of the complications of haemophilia A treatment is the development of anti-FVIII antibodies called an inhibitor. The objective of the treatment of those patients is the elimination of the inhibitor, possibly through inducing immune tolerance (IT). The efficacy of Haemate P in immune tolerance induction both in the first and consecutive lines of treatment has been demonstrated by many reports. Replacement of highly-purified and recombinant FVIII concentrates in the case of failure to induce IT to concentrates with a high vWF:RCo content may be a beneficial treatment option in another attempt of inducing IT.

      The identification of the new form of hemoglobin in fetus red blood cells (HbF), different from adult hemoglobin (HbA), was made over one hundred years ago. Since this time, various methods of fetal hemoglobin measurement have been designed. Most of them are based on the different biochemical characteristics of HbF. Fetal hemoglobin's affinity for oxygen is substantially greater than that of adult hemoglobin. The first techniques for the determination of fetal hemoglobin were based on its resistance to denaturation by alkaline solutions. Currently, the measurement of hemoglobin F is an important part of diagnosis of sickle cell disease, thalassemia, hereditary persistence of fetal hemoglobin, and fetomaternal hemorrhage. Amongst the most commonly used and clinically important methods, high-performance liquid chromatography, capillary electrophoresis, isoelectric focusing, capillary isoelectric focusing, Kleihauer–Betke test, and flow cytometry should be listed.

      We report a case of 18-year-old male patient who 5.5 months after allogeneic hematopoietic stem cell transplant (HSCT) developed severe abdominal pain not responding to high dose of opioids. The pain was accompanied by gradually increasing activity of liver enzymes and bilirubin concentration. The patient had a history of acute GVHD and was on steroid taper. Importantly, he was also temporarily off standard acyclovir prophylaxis. Provisional diagnosis of acute cholecystitis was made, however, cholecystectomy did not improve patient's condition. Clinical picture of severe abdominal pain without clear surgical cause, resistant to high doses of opiates with increasing activity of liver enzymes was highly suspicious of visceral varicella zoster virus (VZV) reactivation. Immediate introduction of intravenous acyclovir led to full recovery and complete resolution of abdominal pain. We conclude that reactivation of latent VZV with absent or delayed occurrence of characteristic skin vesicles may still pose a diagnostic challenge resulting in delay of the proper diagnosis and start of life saving antiviral treatment. Severe intractable pain in HSCT recipients with increasing activity of liver enzymes should evoke high index of suspicion of the possible disseminated VZV and impose start of empirical treatment with high dose acyclovir.

      Infections are the most serious complications in patients undergoing hematopoietic cell transplantation (HCT). Vaccinations occur to be undeniably one of the most important prophylactic strategies and are routinely recommended in the post-transplantation period. Their use reduces the incidence of infections and infection-related mortality. In this paper, we present the current guidelines for active immunization after HCT for the Polish patient population as worked out by the Polish Adult Leukemia Group (PALG). The guidelines include the recommended vaccines, the optional vaccines and vaccination with live pathogens. The management in specific situations such as graft versus host disease and for HCT recipients travelling to exotic countries is clarified. We also present the proposal for organization of the vaccination program in transplant centers. The improvement in realization of the vaccination protocol is one of the key aspects of post-transplantation care in Poland.

      Fetal/neonatal alloimmune thrombocytopenia (FNAIT) is defined as a platelet count <150,000/μL due to reaction between maternal antibodies and antigens located on thrombocytes of the fetus/neonate. Such a kind of pathology occurs when a mother does not possess specific human platelet antigens (HPA), which are inherited as an infant from the father. HPA-1a is an antigen that most often causes FNAIT in the Caucasian race. Frequency of FNAIT has been estimated as 1:350–1:5000. In the pathogenesis of FNAIT, the mother organism is immunized and produces alloantibodies from which IgG pass through the placenta, enter fetal circulatory system and cause platelet destruction. It usually takes place at the end of the second trimester. FNAIT can occur in the first pregnancy; nonetheless, it is more probable and connected with higher severity in subsequent gestations. It is caused by the fact that immunization usually takes place during the first labour, which enables production of alloantibodies in the next pregnancies. Nevertheless, other ways of immunization are also possible, which ensures that FNAIT cases in the first pregnancy are not casuistic and occur more often than RhD hemolytic disease of the newborn. Thrombocytopenia leads to coagulation disorders, and consequently to bleedings. FNAIT can be manifested not only by some petechiae on the skin, but also by severe hemorrhages in the body cavities and gastrointestinal tract or by intracranial hemorrhages (ICH). In case the symptoms are presented by an infant, platelet transfusions are performed, and IVIG (intravenous immunoglobulin) therapy is administered.

      Advanced arthropathy mainly of the knee, hip or ankle joint occurs even in young adults with haemophilia. It has been proved that physical training increases isometric muscular strength and proprioceptive performance in haemophilia patients. The aim of this study was to present the new methods of physiotherapy process and their effect in patients with haemophilic arthropathy. Five subjects, aged from 32 to 42 years, with severe haemophilia A or B attended physiotherapy in a outpatient ambulatory setting over a 3-month period. The following treatment modalities were performed: walking on AlterG anti-gravity treadmill, deep penetrating electromagnetic stimulation (Salus Talent), manual physical therapy, mobilization and manipulation techniques, active muscle-strengthening exercises, post isometric relaxation (PIR) muscle energy techniques, as well as exercises for improvement of coordination, postural equilibrium and proprioception exercises using sensorimotor discs. The HJHS (Haemophilia Joint Health Score) has been used to assess the effectiveness of the treatment, VAS scale (Visual Analog Scale) to assess level of pain, TUG test (Timed Up and Go) to assess mobility as well as dynamic and static balance. Strength of the muscles acting on the joints improved, swelling of joints diminished and the level of pain decreased. An improvement of the dynamic and static balance was found as well. The range of motion did not change. Physiotherapy process did not provoke bleeding episodes in patients with haemophilic arthropathy included to the study.

      Considerable advances have been made in treatment of acute lymphoblastic leukemia (ALL) with an overall survival rate of 85% in children, and with a great improvement in adults. Despite this improvements and the accessibility of hematopoietic stem cell transplantation, relapsed ALL remains a leading cause of childhood mortality emphasizing the need of new approaches on therapy. Understanding of the pathobiology and genetic alteration of ALL has been enhanced by developing molecular technologies including microarray analysis and genome sequencing. These studies have helped identifying mutations in key signaling pathways and revolutionized the treatment of ALL by drugs which specifically target the genetic defects of leukemia cells, such as tyrosine kinase inhibitors. In this paper, we review the clinically important Genetic Alterations in ALL.

      Background Chronic anaemia mainly thalassaemia and sickle cell anaemia are inherited disorders of haemoglobin. Presently about 7% of the world's populations are carriers of a potentially pathological haemoglobin gene. Sickle cell disease is a common haemoglobinopathy in Nigeria but recently cases of β-thalassaemia traits are becoming prominent. This study aimed at screening for β-thalassaemia in adults and children with chronic anaemia in Nigeria by assessing the patients’ level of haemoglobin F, haemoglobin A2 and red cell indices. Materials and methods Haemoglobin F and HbA2 were determined in the chronic anaemia patients by Alkaline Denaturation Method and Beta-Thal HbA2 Quick Column Procedure respectively. Haemoglobin genotype was determined by Haemoglobin Electrophoresis at alkaline medium while Complete Blood count was estimated using Sysmex KX-2IN Autoanalyser. Results The mean HbF, HbA2, HCT, MCV, MCH and MCHC of the children and adults are 2.56±0.46 and 2.45±0.87; 2.05±0.25 and 1.89±0.60; (20.96±3.56) and (21.15±3.12); (78.69±14.11) and (81.58±12.59); (23.07±7.36) (22.74±5.39); (31.23±14.32) and (27.52±3.84) respectively. Four percent (2 subjects) of each adult and children population had increased HbF level (>1.5%) and HbA2 levels (>2.8%) and these subjects are composed of 2 children with haemoglobin genotype AA and two adult with haemoglobin genotypes SS. Conclusions The outcome of this study reiterates the emergence of β-thalassaemia traits and iron deficiency anaemia in different parts of Nigeria irrespective of their haemoglobin genotype status. This requires adequate specialized intervention for their diagnosis and treatment. There is therefore the need for subsequent molecular analysis to determine the β-thalassaemia genes present in the studied community.
