    Zespół del5q stanowi jednostkę chorobową należącą do zespołów mielodysplastcznych. Charakteryzuje się ona niedokrwistością makrocytarną z towarzyszącą nadpłytkowością. Występuje najczęściej u kobiet i związany jest z niskim ryzykiem transformacji do ostrej białaczki. Obecnie standardową terapią jest leczenie lenalidomidem, które pozwala na osiągnięcie wyższego odsetka uniezależnienia od transfuzji oraz odpowiedzi cytogenetycznych w grupie chorych z delecją 5q.Del5q syndrome is myelodysplastic syndrome with well-known clinical manifestation of disease in the form of macrocytic anemia, which can be commonly accompanied by thrombocythemia. The disease is more common in women and is characterized by a relatively low percentage of transformation in acute myeloid leukemia. Currently the treatment of choice in this group of patients is lenalidomide, which allows to achieve higher rate of transfusion independence and cytogenetic responses

    The migration, survival and proliferation of cells is the basis for all physiologic and pathologic processes in the human body. All these reactions are regulated by a complex chemokine network that guides lymphocytes homing, chemotaxis, adhesion and interplay between immunologic system response cells. Chemokines are also responsible for metastatic dissemination of cancers, including Hodgkin&#8217;s and non-Hodgkin&#8217;s lymphomas. The purpose of this study was to determine chemokine gene expression (CXCL8, CXCL10, CCL2, CCL3, CCL4 and CCL5) in lymphoma lymph nodes compared to their expression in reactive lymph nodes. We also analyzed the influence of chemokine gene expression on the survival of lymphoma patients. Chemokine gene expression was evaluated in 37 lymphoma lymph nodes and in 25 samples of reactive lymph nodes. Gene expression of chemokines CXCL8, CXCL10, CCL2, CCL3, CCL4 and CCL5 was measured using the PCR method. Statistical analysis was performed using CSS Statistica for Windows (version 7.0) software. Probability values < < 0.05 were considered statistically significant and those between 0.05 and 0.1 as indicative of a trend. We found lower CXCL8 and CXCL10 gene expression in lymphoma lymph nodes compared to reactive lymph nodes. In the cases of CCL2 and CCL3, expression in lymphomas was higher than in reactive lymph nodes. Patients with high expression of CCL2 and CXCL10 had shorter survival.

    Patients with multiple myeloma (MM) treated with conventional chemotherapy have an averagesurvival of approximately three years. High dose chemotherapy followed by autologous stem cell transplantation(ASCT), first introduced in the mid-1980s, is now considered the standard therapy for almost all patientswith multiple myeloma, because it prolongs overall survival and disease free survival. Between November 1997and October 2006, 122 patients with MM (58 females, 64 males, median age 51.0 years [± 7.98] range: 30–66years) were transplanted in the Department of Hematooncology and Bone Marrow Transplantation at the MedicalUniversity of Lublin: 47 patients were in complete remission or in unconfirmed complete remission,66 patients were in partial remission, and nine had stable disease. Of these, there were 95 patients with IgG myeloma,16 with IgA myeloma, one with IgG/IgA, one with IgM myeloma, five with non secretory type, two withsolitary tumor and two with LCD myeloma. According to Durie-Salmon, 62 patients had stage III of the disease,46 had stage II and four had stage I. Most patients (69/122) were transplanted after two or more cycles ofchemotherapy, 48 patients were transplanted after one cycle of chemotherapy, one patient after surgery and rtg--therapy and four patients had not been treated. In mobilisation procedure, the patients received a single infusionof cyclophosphamide (4–6 g/m2) or etoposide 1.6 g/m2 followed by daily administration of G-CSF until theperipheral stem cells harvest. The number of median harvest sessions was 2.0 (± 0.89) (range: 1–5). An averageof 7.09 (± 33.28) × 106 CD34+ cells/kg were collected from each patient (range: 1.8–111.0 × 106/kg). Conditioningregimen consisted of high dose melphalan 60–210 mg/m2 without TBI. An average of 3.04 (± 11.59) × 106CD34+ cells/kg were transplanted to each patient. Fatal complications occured in four patients (treatment--related mortality = 3.2%). In all patients there was regeneration of hematopoiesis. The median number of daysfor recovery to ANC > 0.5 × 109/l was 13 (± 4.69) (range: 10–38) and platelets recovery to > 50 × 109/l was 25days (± 11.65) (range: 12–45). Median time of hospitalization was 22 days (± 7.14) (range: 14–50). Patientswere evaluated on day 100 after transplantation: 74.9% achieved CR and nCR, 14.3% were in PR, 5.4% had SDand 5.4% had progressed. Median of OS was 45 months (± 30.67). OS at 3-years was 84% and at 7-years 59%.Median PFS was 25 months (± 26.13). PFS at 3-years was 68%, and at 7-years was 43%. At present (November2009) 52 patients (42%) are still alive. High-dose chemotherapy followed by autologous stem cell transplantationis a valuable, well tolerated method of treatment for patients with MM that allows the achievement of long--lasting survival

    Neurofibromatosis 1 (NF-1) is an autosomal dominant genodermatosis with an increased risk of developing mesenchymal malignancies.A 28-year-old woman with NF-1 was admitted to our Department for deep ulcers on the right thigh. The ulcerations had appeared about two years earlier, and were initially diagnosed as pyoderma gangrenosum. The patient received immunosuppressive therapy but only marginal improvement was observed. Several months later, the disease progressed, so a skin biopsy was taken, establishing cytophagic histiocytic panniculitis. The patient was admitted to our Department for further therapy. After re-evaluation of histological slides, while taking into account the clinical presentation and previously established histological diagnosis, subcutaneous panniculitis-like T cell lymphoma (SPTL) was diagnosed. Chemotherapy (combination of fludarabine and cyclophosphamide) was started, resulting in almost complete remission of malignant lesions.To the best of our knowledge, this is the first report of the development of SPTL in NF-1.</span

    POMALIDOMIDE – A new immunomodulatory drug in the treatment of multiple myeloma

    Get PDF
    Multiple myeloma (MM) is a haematological disease characterized by plasma cells proliferation in bone marrow associated with damage of organs – mainly kidneys and bones. Previous therapies significantly extended the survival of patients, but still relapse is 100%. In February 2013, in USA, the Food and Drug Administration (FDA) introduced to therapy a new immunomodulatory drug – pomalidomide. In European Union this drug under the name IMNOVID was registered in August 2013. The authors review the mechanisms of action, pharmacokinetic and clinical properties of pomalidomide. The data discussed in this article come from publications on clinical trials I, II and III phase. It seems this drug may be a breakthrough in the treatment of MM

    High soluble transferrin receptor in patients with heart failure:a measure of iron deficiency and a strong predictor of mortality

    Background: Iron deficiency (ID) is frequent in heart failure (HF), linked with exercise intolerance and poor prognosis. Intravenous iron repletion improves clinical status in HF patients with LVEF≤45%. However, uncertainty exists about the accuracy of serum biomarkers in diagnosing ID. Study Aims: 1) to identify the iron biomarker with the greatest accuracy for the diagnosis of ID in bone marrow in patients with ischaemic HF; 2) to establish the prevalence of ID using this biomarker and its prognostic value in HF patients. Methods and Results: Bone marrow was stained for iron in 30 patients with ischaemic HF with LVEF≤45% and 10 healthy controls, and ID was diagnosed for 0‐1 grades (Gale scale). 791 patients with HF with LVEF≤45% were prospectively followed‐up for 3 years. Serum ferritin, transferrin saturation, soluble transferrin receptor (sTfR) were assessed as iron biomarkers. Most patients with HF (25, 83%) had ID in bone marrow, but none of the controls (p&lt;0.001). Serum sTfR had the best accuracy in predicting ID in bone marrow (AUC: 0.920, 95%CI: 0.761‐0.987, for cut‐off 1.25 mg/L sensitivity 84%, specificity 100%). Serum sTfR was ≥1.25 mg/L in 47% of HF patients, in 56% and 46% of anaemics and non‐anaemics, respectively (p&lt;0.05). The reclassification methods revealed that serum sTfR significantly added the prognostic value to the baseline prognostic model, and to the greater extent than plasma NT‐proBNP. Based on internal derivation and validation procedures, serum sTfR ≥1.41 mg/L was the optimal threshold for predicting 3‐year mortality, independent of other established variables. Conclusions: High serum sTfR accurately reflects depleted iron stores in bone marrow in patients with HF, and identifies those with a high 3‐year mortality

    This work was partially supported by intramural funds of the University of Pisa, DKFZ, and University Hospital of Southern Jutland, Denmark, and by a grant of the French National Cancer Institute (INCA). The authors wish to thank Dr. Dominic Edelmann (Division of Biostatistics, DKFZ) for helpful advice about data analysis.There is overwhelming epidemiologic evidence that the risk of multiple myeloma (MM) has a solid genetic background. Genome-wide association studies (GWAS) have identified 23 risk loci that contribute to the genetic susceptibility of MM, but have low individual penetrance. Combining the SNPs in a polygenic risk score (PRS) is a possible approach to improve their usefulness. Using 2361 MM cases and 1415 controls from the International Multiple Myeloma rESEarch (IMMEnSE) consortium, we computed a weighted and an unweighted PRS. We observed associations with MM risk with OR = 3.44, 95% CI 2.53-4.69, p = 3.55 x 10(-15) for the highest vs. lowest quintile of the weighted score, and OR = 3.18, 95% CI 2.1 = 34-4.33, p = 1.62 x 10(-13) for the highest vs. lowest quintile of the unweighted score. We found a convincing association of a PRS generated with 23 SNPs and risk of MM. Our work provides additional validation of previously discovered MM risk variants and of their combination into a PRS, which is a first step towards the use of genetics for risk stratification in the general population.University of Pisa, DKFZUniversity Hospital of Southern Jutland, DenmarkInstitut National du Cancer (INCA) Franc
