- Abstract
Background: Maintenance therapy following autologous stem cell transplantation (ASCT) can delay disease progression and prolong survival in patients with multiple myeloma. Ixazomib is ideally suited for maintenance therapy given its convenient once-weekly oral dosing and low toxicity profile. In this study, we aimed to determine the safety and efficacy of ixazomib as maintenance therapy following ASCT. Methods: The phase 3, double-blind, placebo-controlled TOURMALINE-MM3 study took place in 167 clinical or hospital sites in 30 countries in Europe, the Middle East, Africa, Asia, and North and South America. Eligible participants were adults with a confirmed diagnosis of symptomatic multiple myeloma according to International Myeloma Working Group criteria who had achieved at least a partial response after undergoing standard-of-care induction therapy followed by high-dose melphalan (200 mg/m2) conditioning and single ASCT within 12 months of diagnosis. Patients were randomly assigned in a 3:2 ratio to oral ixazomib or matching placebo on days 1, 8, and 15 in 28-day cycles for 2 years following induction, high-dose therapy, and transplantation. The initial 3 mg dose was increased to 4 mg from cycle 5 if tolerated during cycles 1–4. Randomisation was stratified by induction regimen, pre-induction disease stage, and response post-transplantation. The primary endpoint was progression-free survival (PFS) by intention-to-treat analysis. Safety was assessed in all patients who received at least one dose of ixazomib or placebo, according to treatment actually received. This trial is registered with ClinicalTrials.gov, number NCT02181413, and follow-up is ongoing. Findings: Between July 31, 2014, and March 14, 2016, 656 patients were enrolled and randomly assigned to receive ixazomib maintenance therapy (n=395) or placebo (n=261). With a median follow-up of 31 months (IQR 27·3–35·7), we observed a 28% reduction in the risk of progression or death with ixazomib versus placebo (median PFS 26·5 months [95% CI 23·7–33·8] vs 21·3 months [18·0–24·7]; hazard ratio 0·72, 95% CI 0·58–0·89; p=0·0023). No increase in second malignancies was noted with ixazomib therapy (12 [3%] patients) compared with placebo (eight [3%] patients) at the time of this analysis. 108 (27%) of 394 patients in the ixazomib group and 51 (20%) of 259 patients in the placebo group experienced serious adverse events. During the treatment period, one patient died in the ixazomib group and none died in the placebo group. Interpretation: Ixazomib maintenance prolongs PFS and represents an additional option for post-transplant maintenance therapy in patients with newly diagnosed multiple myeloma.

- Abstract
Multiple myeloma (MM) remains an incurable disease, with little information available on its management in real-world clinical practice. The results of the present prospective, noninterventional observational study revealed great diversity in the treatment regimens used to treat MM. Our results also provide data to inform health economic, pharmacoepidemiologic, and outcomes research, providing a framework for the design of protocols to improve the outcomes of patients with MM. Background: The present prospective, multinational, noninterventional study aimed to document and describe real-world treatment regimens and disease progression in multiple myeloma (MM) patients. Patients and Methods: Adult patients initiating any new MM therapy from October 2010 to October 2012 were eligible. A multistage patient/site recruitment model was applied to minimize the selection bias; enrollment was stratified by country, region, and practice type. The patient medical and disease features, treatment history, and remission status were recorded at baseline, and prospective data on treatment, efficacy, and safety were collected electronically every 3 months. Results: A total of 2358 patients were enrolled. Of these patients, 775 and 1583 did and did not undergo stem cell transplantation (SCT) at any time during treatment, respectively. Of the patients in the SCT and non-SCT groups, 49%, 21%, 14%, and 15% and 57%, 20%, 12% and 10% were enrolled at treatment line 1, 2, 3, and ≥ 4, respectively. In the SCT and non-SCT groups, 45% and 54% of the patients had received bortezomib-based therapy without thalidomide/lenalidomide, 12% and 18% had received thalidomide/lenalidomide-based therapy without bortezomib, and 30% and 4% had received bortezomib plus thalidomide/lenalidomide-based therapy as frontline treatment, respectively. The corresponding proportions of SCT and non-SCT patients in lines 2, 3, and ≥ 4 were 45% and 37%, 30% and 37%, and 12% and 3%, 33% and 27%, 35% and 32%, and 8% and 2%, and 27% and 27%, 27% and 23%, and 6% and 4%, respectively. In the SCT and non-SCT patients, the overall response rate was 86% to 97% and 64% to 85% in line 1, 74% to 78% and 59% to 68% in line 2, 55% to 83% and 48% to 60% in line 3, and 49% to 65% and 36% and 45% in line 4, respectively, for regimens that included bortezomib and/or thalidomide/lenalidomide. Conclusion: The results of our prospective study have revealed great diversity in the treatment regimens used to manage MM in real-life practice. This diversity was linked to factors such as novel agent accessibility and evolving treatment recommendations. Our results provide insight into associated clinical benefits. © 2018 The Authors

- Abstract
OBJECTIVE: Essential thrombocythaemia (ET) is a myeloproliferative neoplasm in which there is an increased risk of thrombotic complications. The conventional thrombosis risk assessment of these patients is based on an age over 60 and a history of thrombosis. The aim of this report is to analyse the contribution of cardiovascular risk (CV) factors as possible additional thrombotic risk factors in the thrombotic complications seen in ET. PATIENTS AND METHODS: One hundred and one ET patients (72 females and 29 males with a median age of 61 years) were enrolled between 1999 and 2011. Mann-Whitney and multivariate binary logistic regression tests were performed. The Kaplan-Meier method followed by the log-rank test was used to evaluate the probability of thrombosis-free survival. RESULTS: The presence of one or two or more CV risk factors significantly increased the risk of thrombosis. Separately, the contribution of high blood pressure and hyperlipidaemia proved to be influential, whereas tobacco use, diabetes mellitus and obesity were not significant. Significant differences were revealed in the probability of thrombosis-free survival between patients without CV risk factors and those with at least one CV risk factor, and between those with at most one CV risk factor and those with two or more CV risk factors. CONCLUSIONS: On the basis of the results on the current cohort, it is suggested that CV risk factors may influence the thrombotic complications in ET. [ABSTRACT FROM AUTHOR]

- Abstract
OBJECTIVE: In polycythaemia vera (PV) and essential thrombocythaemia (ET), the life expectancy of the patients is greatly affected by thrombotic events. An investigation was performed of the potential association of PV/ET, and thrombotic complications with cardiovascular (CV) risk factors, a leukocyte count at the haematological diagnosis > 11.1 G/L, and the JAK2V617F mutation. PATIENTS AND METHODS: In the period 1998-2011, 128 women with a median age of 62 years were enrolled. RESULTS: The risk of thrombotic events before the diagnosis was 32.8% (42/128), while in the follow-up period it was 10.2% (13/128).The difference in the probability of thrombosis-free survival between those with at most one CV risk factor and those with two or more CV risk factors was significant (p = 0.005). The presence of two or more CV risk factors (univariate: p = 0.011; multivariate: relative risk: 4.728, 95% CI 1.312-17.040; p = 0.018) significantly increased the risk of thrombosis. Univariate analyses revealed that high blood pressure (p = 0.001), hyperlipidaemia (p = 0.005) and cigarette smoking (p = 0.051) were associated with a significantly higher risk of thrombosis. Analyses of the influence of the leukocyte count (univariate: p = 0.424; multivariate: relative risk: 1.407, 95% CI 0.359-5.507; p = 0.624) and the JAK2V617F mutation (univariate: p = 0.367; multivariate: relative risk: 1.428, 95% CI 0.316-6.460; p = 0.643) on subsequent thrombotic complications resulted in a non-signicant tendency. CONCLUSIONS: Female patients who display CV risk factors (high blood pressure, hyperlipidaemia and/or cigarette smoking) and PV or ET may well be at a higher risk of thrombotic events and require special consideration as concerns as the prevention and management of thrombotic events.

- Abstract
From a dermatological aspect, it posed a considerable challenge the skin-limited form of mastocytosis, urticaria pigmentosa and indolent systemic mastocytosis (ISM) with cutaneous lesions. Despite the favourable prognosis, lifelong dermatological control is needed, during which the average symptomatic therapy does not always seem adequate. We report here the case of a female ISM patient with recurrent cutaneous symptoms that impaired her quality of life, with a follow-up time of 27 years. During this long follow-up period, the cutaneous lesions could be controlled by antihistamines, leukotriene antagonists, glucocorticoids, local immunosuppressants or local UV radiation for only relatively short periods. Imatinib mesylate was, therefore, introduced in an attempt to control the cutaneous lesions. Tyrosine kinase inhibition is an unusual dermatological therapeutic option. This case illustrates that imatinib mesylate was a good choice with which to achieve a reduction of the skin lesions in this KIT D816V mutation-negative disease: it led to a temporary appreciable improvement of the patient's quality of life.

[Background]: Maintenance therapy following autologous stem cell transplantation (ASCT) can delay disease progression and prolong survival in patients with multiple myeloma. Ixazomib is ideally suited for maintenance therapy given its convenient once-weekly oral dosing and low toxicity profile. In this study, we aimed to determine the safety and efficacy of ixazomib as maintenance therapy following ASCT. [Methods]: The phase 3, double-blind, placebo-controlled TOURMALINE-MM3 study took place in 167 clinical or hospital sites in 30 countries in Europe, the Middle East, Africa, Asia, and North and South America. Eligible participants were adults with a confirmed diagnosis of symptomatic multiple myeloma according to International Myeloma Working Group criteria who had achieved at least a partial response after undergoing standard-of-care induction therapy followed by high-dose melphalan (200 mg/m²) conditioning and single ASCT within 12 months of diagnosis. Patients were randomly assigned in a 3:2 ratio to oral ixazomib or matching placebo on days 1, 8, and 15 in 28-day cycles for 2 years following induction, high-dose therapy, and transplantation. The initial 3 mg dose was increased to 4 mg from cycle 5 if tolerated during cycles 1–4. Randomisation was stratified by induction regimen, pre-induction disease stage, and response post-transplantation. The primary endpoint was progression-free survival (PFS) by intention-to-treat analysis. Safety was assessed in all patients who received at least one dose of ixazomib or placebo, according to treatment actually received. This trial is registered with ClinicalTrials.gov, number NCT02181413, and follow-up is ongoing. [Findings]: Between July 31, 2014, and March 14, 2016, 656 patients were enrolled and randomly assigned to receive ixazomib maintenance therapy (n=395) or placebo (n=261). With a median follow-up of 31 months (IQR 27·3–35·7), we observed a 28% reduction in the risk of progression or death with ixazomib versus placebo (median PFS 26·5 months [95% CI 23·7–33·8] vs 21·3 months [18·0–24·7]; hazard ratio 0·72, 95% CI 0·58–0·89; p=0·0023). No increase in second malignancies was noted with ixazomib therapy (12 [3%] patients) compared with placebo (eight [3%] patients) at the time of this analysis. 108 (27%) of 394 patients in the ixazomib group and 51 (20%) of 259 patients in the placebo group experienced serious adverse events. During the treatment period, one patient died in the ixazomib group and none died in the placebo group. [Interpretation]: Ixazomib maintenance prolongs PFS and represents an additional option for post-transplant maintenance therapy in patients with newly diagnosed multiple myeloma, This study was sponsored by Millennium Pharmaceuticals, a wholly owned subsidiary of Takeda Pharmaceutical Company.

- Abstract
TP53 aberrations predict chemoresistance and represent a contraindication for the use of standard chemoimmunotherapy in chronic lymphocytic leukaemia (CLL). Recent next-generation sequencing (NGS)-based studies have identified frequent low-burden TP53 mutations with variant allele frequencies below 10%, but the clinical impact of these low-burden TP53 mutations is still a matter of debate. In this study, we aimed to scrutinise the subclonal architecture and clinical impact of TP53 mutations using a sensitive, NGS-based mutation analysis in a 'real-world' cohort of 901 patients with CLL. In total, 225 TP53 mutations were identified in 17.5% (158/901) of the patients; 48% of these alterations represented high-burden mutations, while 52% were low-burden TP53 mutations. Low-burden mutations as sole alterations were identified in 39% (62/158) of all mutated cases with 82% (51/62) of these being represented by a single low-burden TP53 mutation. Patients harbouring low-burden TP53 mutations had significantly lower time to first treatment compared to patients with wild-type TP53. Our study has expanded the knowledge on the frequency, clonal architecture, and clinical impact of low-burden TP53 mutations. By demonstrating that patients with sole low-burden TP53 variants represent more than one-third of patients with TP53 mutations and have an increased risk for treatment initiation, our findings strengthen the need to redefine the threshold of TP53 variant reporting to below 10% in the routine diagnostic setting., (© 2023 The Authors.

- Abstract
Peripheral T-cell lymphomas (PTCLs) expressing multiple follicular T helper (TFH) cell-related antigens are now classified as TFH lymphomas (TFHL), including angioimmunoblastic, follicular, and not otherwise specified (NOS) types. CXCR5 is the TFH cell-defining chemokine receptor that, together with its ligand CXCL13, plays a critical role in the development of follicles and the positioning of TFH and B cells within follicles. A comprehensive immunomorphologic study was performed to investigate the expression pattern of CXCR5 in a large cohort of nodal PTCLs, particularly those with a TFH cell phenotype, and to compare its expression with six other TFH cell-related antigens. We found that CXCR5 is widely expressed in neoplastic TFH cells, except in TFHL-NOS, and represents a specific marker of this lymphoma entity. Our results suggest that CXCR5 directs the distribution of neoplastic T cells in the affected lymph nodes and may influence the formation of the pathognomic pathological FDC network.

- Abstract
Background: Hypereosinophilic syndrome (HES) is a peripheral eosinophilia characterized by elevated absolute eosinophil cell count ( > 1.500 cells/ μ L) and consequent tissue and end-organ damage. Our aim was to evaluate the mitral annular (MA) and/or tricuspid annular (TA) parameters of patients with HES and to determine whether there are any changes in these parameters compared to healthy individuals., Methods: 17 patients with HES were involved in our study, 2 cases were excluded due to suboptimal image quality (mean age of the evaluated patients: 61.7 ± 11.2 years, 10 males). Their data were compared with those of 24 healthy subjects (mean age: 55.2 ± 7.9 years, 12 males) in the control group. Complete echocardiographic examinations were performed including two-dimensional (2D) Doppler echocardiography and three-dimensional echocardiography (3DE) to assess the MA and the TA., Results: Comparing the echocardiographic parameters of the HES patients with those of the healthy volunteers, the following changes were seen: the interventricular septum was significantly thickened in HES patients, no other significant changes were detected between the examined patient groups. End-diastolic and end-systolic MA diameters, areas and perimeters were increased and MA fractional area change and MA fractional shortening were decreased in HES patients. From TA morphological parameters, only end-diastolic TA area and end-systolic TA perimeter were significantly increased in HES patients. Functional TA parameters showed no significant alterations in the HES group. In patients with HES, no correlations could be detected between 2D and 3D echocardiographic data with the examined laboratory findings., Conclusions: The extent of the dilation of the MA is more pronounced than that of the TA in HES. MA functional impairment is present in HES., Competing Interests: The authors declare no conflict of interest. Attila Nemes is serving as one of the Editorial Board members of this journal.

- Abstract
Background: Ibrutinib is widely known as an effective and well-tolerated therapeutical choice of the chronic lymphocytic leukaemia (CLL). However, acquired resistance may occur during the treatment, causing relapse. Early detection of ibrutinib resistance is an important issue, therefore we aimed to find phenotypic markers on CLL cells the expression of which may correlate with the appearance of ibrutinib resistance. Methods: We examined 28 patients' peripheral blood (PB) samples (treatment naïve, ibrutinib sensitive, clinically ibrutinib resistant). The surface markers' expression (CD27, CD69, CD86, CD184, CD185) were measured by flow cytometry. Furthermore, the BTK
C481S resistance mutation was assessed by digital droplet PCR. Moreover, the CLL cells' phenotype of a patient with acquired ibrutinib resistance was observed during the ibrutinib treatment. Results: The expression of CD27 ( p = 0.030) and CD86 ( p = 0.031) became higher in the clinically resistant cohort than in the ibrutinib sensitive cohort. Besides, we found that high CD86 and CD27 expressions were accompanied by BTKC481S mutation. Our prospective study showed that the increase of the expression of CD27, CD69 and CD86 was noticed ahead of the clinical resistance with 3 months. Conclusion: Our study suggests that the changes of the expression of these markers could indicate ibrutinib resistance and the examination of these phenotypic changes may become a part of the patients' follow-up in the future., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Takács, Kotmayer, Czeti, Szalóki, László, Mikala, Márk, Masszi, Farkas, Plander, Weisinger, Demeter, Fekete, Szerafin, Deák, Szaleczky, Sulák, Borbényi and Barna.)- Published

- Abstract
Introduction: Hemophilia is an inherited disorder due to deficiencies in factor VIII (type A) and factor IX (type B). Abnormalities in myocardial mechanics could be theorized due to hemophilia-associated hypocoagubility and related quantitative and qualitative changes of the blood. The present study aimed a detailed assessment of left atrial (LA) volumetric and functional properties in patients with hemophilia using three-dimensional speckle-tracking echocardiography (3DSTE)., Materials and Methods: The study consisted of 12 subjects with hemophilia type A and 2 cases with hemophilia type B (mean age: 40.8 ± 19.1 years, all males). Results of hemophilia patients were compared to that of 23 age-, gender- and risk factor-matched controls (42.4 ± 9.0 years, all males). Routine two-dimensional Doppler echocardiography and 3DSTE were performed in all subjects., Results: LA volumes respecting cardiac cycle did not differ between controls and hemophilia patients. From LA volume-based functional properties, LA stroke volumes were similar between the groups examined in all phases of LA function. While total atrial emptying fraction featuring LA reservoir function was reduced in patients with hemophilia compared to that of controls, passive and active atrial emptying fraction characterizing LA conduit and booster pump functions were similar between the groups. From LA strains, peak mean segmental circumferential and longitudinal LA strains were impaired in patients with hemophilia, other peak LA strains were similar between the groups. LA strains at atrial contraction did not differ between groups of hemophilia patients and controls., Conclusions: Hemophilia is not associated with LA volumetric changes, but mild LA functional abnormalities are present., Competing Interests: There are no conflicts of interest., (Copyright: © 2022 Journal of Cardiovascular Echography.)

- Abstract
Introduction: Amyloidosis is a rare condition due to extracellular deposition of excessive amount of protein in parenchymal tissues including the heart. The present study aimed to test whether cardiac amyloidosis (CA) is associated with morphological and functional abnormalities of the tricuspid annulus (TA). For this aim, the results of patients having CA were compared to age- and gender-matched healthy controls by three-dimensional speckle-tracking echocardiography (3DSTE). Moreover, differences in TA parameters between light-chain CA (AL-CA) and transthyretin CA (TTR-CA) were studies as well., Materials and Methods: The study comprised 27 CA patients (mean age: 62.7 ± 9.1 years, 21 males), their results were compared to those of 20 age- and gender-matched healthy volunteers (59.3 ± 3.8 years, 13 males). Complete two-dimensional Doppler echocardiography and 3DSTE were performed in all CA patients and controls., Results: Dilated end-diastolic and end-systolic TA diameter, area and perimeter could be detected in all CA patients and in the AL-CA and TTR-CA subgroups, as well. Although only a few TTR-CA patients were involved, morphologic TA parameters proved to be tendentiously higher as compared to those of AL-CA patients. Functional parameters of TA were found to be reduced in CA patients, which were more deteriorated in AL-CA patients., Conclusions: Dilated TA is associated with its functional deterioration in CA., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (© 2022 The Author(s).)

- Abstract
Background: Hemophilia is an X-linked inherited disorder primarily affecting males, its major types are type A (deficiency in factor VIII) and B (deficiency in factor IX), and is considered to be the most common severe congenital coagulation factor deficiency. The present study was designed to test whether any differences in left ventricular (LV) rotational mechanics could be demonstrated between male patients with hemophilia and healthy controls using three-dimensional speckle-tracking echocardiography (3DSTE)-derived virtual LV models., Methods: The present study consisted of 17 patients with hemophilia, however, 3 patients were excluded due to insufficient image quality. In the remaining patient population, 12 patients had hemophilia A and 2 patients had hemophilia B (mean age: 42.2±18.9 years, all males). The control group comprised 16 age-matched healthy subjects (46.0±5.9 years, all males)., Results: None of the routine two-dimensional echocardiographic data differ between patients with hemophilia and controls. None of the patients and controls showed ≥ grade 1 valvular regurgitations and had valvular stenoses. In one subject, the near absence of LV twist called as LV "rigid body rotation" could be detected, data of which were managed separately. While 3DSTE-derived apical LV rotation was 3.65 degrees, basal LV rotation proved to be 3.57 degrees leading to 0.08-degree LV apico-basal gradient suggesting counterclockwise LV "rigid body rotation". In the remaining patients, both LV apical rotation (7.25±6.20 vs. 10.39±4.16 degrees, P<0.02) and LV twist (10.24±5.60 vs. 14.38±3.93 degrees, P<0.003) showed significant impairment in patients with hemophilia., Conclusions: LV rotational abnormalities are present in hemophilia with reduced LV apical rotation and twist., Competing Interests: Conflicts of Interest: All authors have completed the ICMJE uniform disclosure form (available at https://dx.doi.org/10.21037/qims-21-30).

- Abstract
Background: Patients with hematological malignancies (HM) are at high risk of mortality from SARS-CoV-2 disease 2019 (COVID-19). A better understanding of risk factors for adverse outcomes may improve clinical management in these patients. We therefore studied baseline characteristics of HM patients developing COVID-19 and analyzed predictors of mortality., Methods: The survey was supported by the Scientific Working Group Infection in Hematology of the European Hematology Association (EHA). Eligible for the analysis were adult patients with HM and laboratory-confirmed COVID-19 observed between March and December 2020., Results: The study sample includes 3801 cases, represented by lymphoproliferative (mainly non-Hodgkin lymphoma n = 1084, myeloma n = 684 and chronic lymphoid leukemia n = 474) and myeloproliferative malignancies (mainly acute myeloid leukemia n = 497 and myelodysplastic syndromes n = 279). Severe/critical COVID-19 was observed in 63.8% of patients (n = 2425). Overall, 2778 (73.1%) of the patients were hospitalized, 689 (18.1%) of whom were admitted to intensive care units (ICUs). Overall, 1185 patients (31.2%) died. The primary cause of death was COVID-19 in 688 patients (58.1%), HM in 173 patients (14.6%), and a combination of both COVID-19 and progressing HM in 155 patients (13.1%). Highest mortality was observed in acute myeloid leukemia (199/497, 40%) and myelodysplastic syndromes (118/279, 42.3%). The mortality rate significantly decreased between the first COVID-19 wave (March-May 2020) and the second wave (October-December 2020) (581/1427, 40.7% vs. 439/1773, 24.8%, p value < 0.0001). In the multivariable analysis, age, active malignancy, chronic cardiac disease, liver disease, renal impairment, smoking history, and ICU stay correlated with mortality. Acute myeloid leukemia was a higher mortality risk than lymphoproliferative diseases., Conclusions: This survey confirms that COVID-19 patients with HM are at high risk of lethal complications. However, improved COVID-19 prevention has reduced mortality despite an increase in the number of reported cases., (© 2021. The Author(s).)

- Abstract
In Hungary, the cost of lenalidomide-based therapy is covered only for relapsed multiple myeloma (MM) patients, therefore lenalidomide is typically used in the second-line either as part of a triplet with proteasome inhibitors or as a doublet. Lenalidomide-dexamethasone is a standard treatment approach for relapsed/refractory MM, and according to recent large randomized clinical trials (RCT, the standard arm of POLLUX, ASPIRE, TOURMALINE), the progression-free survival (PFS) is expected to be approximately 18 months. We surveyed ten Hungarian centers treating MM and collected data of 278 patients treated predominantly after 2016. The median age was 65 years, and patients were distributed roughly equally over the 3 international staging system groups, but patients with high risk cytogenetics were underrepresented. 15.8% of the patients reached complete response, 21.6% very good partial response, 40.6% partial response, 10.8% stable disease, and 2.5% progressed on treatment. The median PFS was unexpectedly long, 24 months, however only 9 months in those with high risk cytogenetics. We found interesting differences between centers regarding corticosteroid type (prednisolone, methylprednisolone or dexamethasone) and dosing, and also regarding the choice of anticoagulation, but the outcome of the various centers were not different. Although the higher equivalent steroid dose resulted in more complete responses, the median PFS of those having lower corticosteroid dose and methylprednisolone were not inferior compared to the ones with higher dose dexamethasone. On multivariate analysis high risk cytogenetics and the number of prior lines remained significant independent prognostic factors regarding PFS ( p < 0.001 and p = 0.005). Our results show that in well-selected patients Lenalidomide-dexamethasone can be a very effective treatment with real-world results that may even outperform those reported in the recent RCTs. This real world information may be more valuable than outdated RCT data when treatment options are discussed with patients., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2021 Varga, Dávid Tóth, Réka Szita, Csukly, Hardi, Gaál-Weisinger, Nagy, Altai, Rencsik, Plander, Szendrei, Kórád, Radványi, Rottek, Deák, Szaleczky, Schneider, Kohl, Kosztolányi, Alizadeh, Lengyel, Modok, Borbényi, Lovas, Váróczy, Illés, Rajnics, Masszi and Mikala.)

- Abstract
Introduction: Hypereosinophilic syndrome (HES) and immunoglobulin light-chain amyloidosis (ALA) are two, rare haematological disorders associated with cardiac alterations. Aim: The goal of the present study was a comparative assessment of left ventricular (LV) deformational parameters in HES and ALA patients using three-dimensional speckle-tracking echocardiography (3DSTE). Method: In the present study, results of 10 HES patients (mean age: 60.9 ± 14.7 years) and 19 ALA patients (mean age: 63.4 ± 7.8 years, 13 males) were analysed. The control group contained 13 age- and gender-matched healthy adults (mean age: 59.2 ± 4.3 years, 5 males). All patients underwent a complete two-dimensional Doppler echocardiography followed by 3DSTE. Results: All basal segmental LV strains were significantly reduced in ALA patients as compared to the control group. Global and mean segmental LV longitudinal strain (LS) values of ALA patients proved to be significantly decreased as compared to those of the healthy control group. During comparison of HES patients and healthy controls, significant difference could be detected in global LV-LS, while segmental basal LV-LS was also significantly reduced in HES patients. Basal LV radial and 3D strains showed significant differences when parameters of HES and ALA patient groups were compared. Conclusion: 3DSTE is a feasible tool for the detailed assessment of LV deformation in HES and ALA patients. Significant LV deformational abnormalities could be detected in both groups. In the case of ALA, these abnormalities are more prominent. Orv Hetil. 2020; 161(5): 169-176.

- Abstract
Introduction: Hypereosinophilic syndrome (HES) is a very heterogeneous group of disorders with varied etiologies characterized by peripheral eosinophilia and eosinophilic tissue/end-organ damage. Three-dimensional speckle-tracking echocardiography (3DSTE) was used for assessment of left ventricular (LV) rotational mechanics in HES patients., Methods: The study comprised 13 HES patients, from which one patient was excluded due to insufficient image quality. The remaining patient population consisted of 12 HES cases (mean age: 59.7 ± 13.7 years, eight males). The control group consisted of 36 healthy volunteers (mean age: 52.9 ± 8.3 years, 23 males). 3DSTE was used for the evaluation of LV rotational abnormalities., Results: Both LV apical rotation (4.86 ± 1.92 degree vs 10.07 ± 3.92 degree, P < .0001) and LV twist (8.52 ± 2.79 degree vs 14.41 ± 4.26 degree, P < .0001) showed significant deteriorations in most of HES patients. Time-to-peak LV apical rotation (380 ± 115 ms vs 344 ± 69 ms, P = .56), LV basal rotation (335 ± 148 ms vs 337 ± 111 ms, P = .89), and LV twist (348 ± 91 ms vs 320 ± 60 ms, P = .64) were not significantly different between HES patients and controls. No correlations could be detected between absolute eosinophil count and eosinophil ratio and apical LV rotation (r = 0.12, P = .51 and r = 0.23, P = .45, respectively) and LV twist (r = 0.24, P = .39 and r = 0.31, P = .34, respectively). In two subjects, the absence of LV twist called LV "rigid body rotation" (RBR) was detected., Conclusions: Reduced LV apical rotation and twist could be demonstrated in HES. LV-RBR could be detected in some HES patients., (© 2019 Wiley Periodicals, Inc.)

- Abstract
Daratumumab is a human anti-CD38 monoclonal antibody used in the treatment of refractory and relapsed multiple myeloma. We investigated the efficacy and safety of daratumumab therapy in a real-world setting. Ninety-nine Hungarian patients were included; 48 received monotherapy, while lenalidomide and bortezomib combinations were administered in 29 and 19 cases, respectively. Overall response rate was assessable in 88 patients, with 12 complete, 10 very good partial, 34 partial, and seven minor responses. At a median duration of follow-up of 18.6 months, median progression-free survival (PFS) among all patients was 17.0 months. These values were inferior in the bortezomib combination and monotherapy groups. Patients with early-stage disease (ISS1) had better survival results than those with stage 2 or 3 myeloma (p = 0.009). Heavily pretreated patients had inferior PFS compared to those with 1-3 therapies (p = 0.035). Patients with impaired renal function had PFS results comparable with those having no kidney involvement. There were 10 fatal infections, and the most frequent adverse events were mild infusion-associated reactions and hematologic toxicities. Our results confirm that daratumumab is an effective treatment option for relapsed/refractory MM with an acceptable safety profile in patients with normal and impaired renal function.

- Abstract
Background: The present prospective, multinational, noninterventional study aimed to document and describe real-world treatment regimens and disease progression in multiple myeloma (MM) patients., Patients and Methods: Adult patients initiating any new MM therapy from October 2010 to October 2012 were eligible. A multistage patient/site recruitment model was applied to minimize the selection bias; enrollment was stratified by country, region, and practice type. The patient medical and disease features, treatment history, and remission status were recorded at baseline, and prospective data on treatment, efficacy, and safety were collected electronically every 3 months., Results: A total of 2358 patients were enrolled. Of these patients, 775 and 1583 did and did not undergo stem cell transplantation (SCT) at any time during treatment, respectively. Of the patients in the SCT and non-SCT groups, 49%, 21%, 14%, and 15% and 57%, 20%, 12% and 10% were enrolled at treatment line 1, 2, 3, and ≥ 4, respectively. In the SCT and non-SCT groups, 45% and 54% of the patients had received bortezomib-based therapy without thalidomide/lenalidomide, 12% and 18% had received thalidomide/lenalidomide-based therapy without bortezomib, and 30% and 4% had received bortezomib plus thalidomide/lenalidomide-based therapy as frontline treatment, respectively. The corresponding proportions of SCT and non-SCT patients in lines 2, 3, and ≥ 4 were 45% and 37%, 30% and 37%, and 12% and 3%, 33% and 27%, 35% and 32%, and 8% and 2%, and 27% and 27%, 27% and 23%, and 6% and 4%, respectively. In the SCT and non-SCT patients, the overall response rate was 86% to 97% and 64% to 85% in line 1, 74% to 78% and 59% to 68% in line 2, 55% to 83% and 48% to 60% in line 3, and 49% to 65% and 36% and 45% in line 4, respectively, for regimens that included bortezomib and/or thalidomide/lenalidomide., Conclusion: The results of our prospective study have revealed great diversity in the treatment regimens used to manage MM in real-life practice. This diversity was linked to factors such as novel agent accessibility and evolving treatment recommendations. Our results provide insight into associated clinical benefits., (Copyright © 2018 The Authors. Published by Elsevier Inc. All rights reserved.)

- Abstract
Background: Light-chain (AL) cardiac amyloidosis (CA) is characterized by fibril deposits, which are composed of monoclonal immunoglobulin light chains. The right ventricle is mostly involved in AL-CA and impairment of its function is a predictor of worse prognosis., Objectives: To characterize the volumetric and functional properties of the right atrium (RA) in AL-CA by three-dimensional speckle-tracking echocardiography (3DSTE)., Methods: A total of 16 patients (mean age: 64.5 ± 10.1 years, 11 males) with AL-CA were examined. Their results were compared to that of 15 age- and gender-matched healthy controls (mean age: 58.9 ± 6.9 years, 8 males). All cases have undergone complete two-dimensional Doppler and 3DSTE. A two-tailed p value of less than 0.05 was considered statistically significant., Results: Significant differences could be demonstrated in RA volumes respecting cardiac cycle. Total (19.2 ± 9.3% vs. 27.9 ± 10.7%, p = 0.02) and active atrial emptying fractions (12.1 ± 8.1 vs. 18.6 ± 9.8%, p = 0.05) were significantly decreased in AL-CA patients. Peak global (16.7 ± 10.3% vs. 31.2 ± 19.4%, p = 0.01) and mean segmental (24.3 ± 11.1% vs. 38.6 ± 17.6%, p =0.01) RA area strains, together with some circumferential, longitudinal and segmental area strain parameters, proved to be reduced in patients with AL-CA. Global longitudinal (4.0 ± 5.2% vs. 8.2 ± 5.5%, p = 0.02) and area (7.8 ± 8.1% vs. 15.9 ± 10.3%, p = 0.03) strains at atrial contraction and some circumferential and area strain parameters at atrial contraction were reduced in AL-CA patients., Conclusion: Significantly increased RA volumes and deteriorated RA functions could be demonstrated in AL-CA.

- Abstract
Follicular lymphoma is a lymphoid malignancy commonly showing slow progression which makes the treatment of the disease challenging. Rituximab monotherapy and rituximab added to standard chemotherapy has been proven to increase survival among patients with advanced stage of the disease. However, the benefit of a rituximab maintenance therapy after induction was still unclear at the time of the initiation of this study. HUSOM was a phase III open-label, single-arm, multi-centre study aimed to assess the efficacy and the safety of the 12 cycles of rituximab (375 mg/m
2 every 8 weeks) maintenance therapy in patients had already presented partial or complete response to R-CVP or R-CHOP. Efficacy endpoints such as event-free survival and overall survival were estimated. Adverse events were recorded during the entire course of the study. A total number of 124 patients were enrolled by 15 Hungarian study sites. Out of these, 86 patients received 12 cycles of rituximab and 69 patients completed the 3-year follow-up phase as well. The probabilities of the event free survival and progression at 4.3 years were estimated to be 70.3% and 74.4%, respectively. The overall and the disease free survival at 4 years were estimated to be 90.7% and 87.9%, respectively. A total number of 85 adverse events were reported during the study out of which 5 AEs were considered to be related to the administration of rituximab. Analyses of the efficacy variables have revealed comparable results to those reported by controlled clinical trials (EORTC 20981, PRIMA) conducted in parallel with the HUSOM study.- Published

- Abstract
Objective: Cardiac amyloidosis (CA) is as an infiltrative disorder primarily caused by extracellular tissue deposition of amyloid fibrils in the myocardial interstitium. The current study was designed to test whether alterations in ascending aortic elastic properties could be detected by echocardiography in CA patients, and to compare their results to controls., Patients and Methods: We included 19 CA patients from which CA proved to be AL amyloidosis in 17 cases and transthyretin (TTR) amyloidosis in 2 cases. Their results were compared to 20 age-, gender-, and risk factor-matched controls., Results: There was significantly greater interventricular septum and left ventricular (LV) posterior wall thickness, lower LV ejection fraction and greater E/A in CA patients than in controls, suggesting systolic, and diastolic dysfunction. CA patients also showed significantly reduced aortic strain and pulsatile change in aortic diameter, and increased aortic stiffness index., Conclusion: These results suggest increased aortic stiffness in CA patients., (© 2017 Wiley Periodicals, Inc.)

- Abstract
Background: Philadelphia negative myeloproliferative neoplasms (MPNs) are characterized by frequent mutations of driver genes including JAK2, CALR and MPL. While the influence of JAK2 V617F mutant allele burden on the clinical phenotype of MPN patients is well-described, the impact of CALR mutant allele burden on clinical features needs further investigation., Patients and Methods: Quantitative assessment of JAK2 and CALR mutations was performed on diagnostic DNA samples from 425 essential thrombocythemia (ET) and 227 primary myelofibrosis patients using real-time quantitative PCR and fragment length analysis. Characterization of CALR mutations and detection of MPL mutations were performed by Sanger sequencing., Results: Twelve novel CALR mutations have been identified. ET patients with CALR
mut load exceeding the median value exhibited lower hemoglobin values (12.0 vs. 13.6 g/dL), higher LDH levels (510 vs. 351 IU/L) and higher rate of myelofibrotic transformation (19% vs. 5%). The CALRmut load was higher among ET patients presenting with splenomegaly compared to those without splenomegaly (50.0% vs. 43.5%)., Conclusion: Our study confirms the clinical significance of driver mutational status and JAK2mut load in MPNs; in addition, unravels a novel clinical association between high CALRmut load and a more proliferative phenotype in ET., (Copyright © 2017 Elsevier Ltd.

- Abstract
Background: Persistent eosinophilia and eosinophil-mediated single- or multiple-organ damage are typical features of hypereosinophilic syndrome (HES). Theoretically, eosinophilic infiltration of the ascending aortic wall could not be excluded in HES, therefore the present study aimed to test whether HES is associated with abnormalities in aortic elastic properties., Methods: The present study comprised 10 HES patients (mean age: 57.6±10.1 years, 5 males) without known cardiovascular disease, their results were compared to 19 age-, gender- and risk factor-matched controls (59.2±4.2 years, 15 males). Complete two-dimensional Doppler echocardiography with measurement of echocardiographic aortic elastic properties was performed in all HES cases and controls., Results: Although neither systolic (30.6±3.4 vs. 30.1±3.6 mm, P=ns), nor diastolic (28.7±3.6 vs. 27.8±3.2 mm, P=ns) aortic diameter differed significantly between HES patients and matched controls, significantly increased aortic stiffness index (11.19±5.65 vs. 7.04±2.97, P<0.05) could be demonstrated in HES patients., Conclusions: Increased aortic stiffness could be demonstrated in HES patients in their early necrotic phase., Competing Interests: Conflicts of Interest: The authors have no conflicts of interest to declare.

- Abstract
Introduction: While cardiac amyloidosis (CA) is a rare systemic disease characterized by extracellular deposition of protein-derived fibrils, hypertrophic cardiomyopathy (HCM) is histopathologically characterized by myocyte hypertrophy and disarray, interstitial fibrosis, and small intramural coronary arteriole dysplasia. The aim of the present study was to compare left atrial (LA) volumetric and functional characteristics between light-chain (AL) CA and HCM by three-dimensional (3D) speckle-tracking echocardiography (STE)., Methods: The AL-CA group initially consisted of 17 patients with AL-CA, but one patient was excluded due to inadequate image quality, and so the study population consisted of 16 patients (mean age: 64.0±9.6 years, five men). Their results were compared with data on 20 age-matched HCM patients (mean age: 59.8±5.2 years, 10 men) and on 16 age-matched healthy controls (mean age: 58.2±7.2 years, six men). Complete two-dimensional Doppler echocardiography and 3D-STE were performed in all cases., Results: Significantly increased LA volumes were observed in both AL-CA and HCM compared with the control group. Only active atrial emptying fraction was found to be significantly reduced in AL-CA patients compared to controls. Peak global and mean segmental circumferential, longitudinal and area strains showed significant reductions in AL-CA patients compared with controls, but only peak mean segmental longitudinal strain differed significantly between HCM patients and controls. While no differences were demonstrated in global and mean segmental strain at atrial contraction between HCM patients and controls, AL-CA patients showed reductions in certain strain parameters compared to controls and HCM patients., Conclusions: Different patterns of LA functional characteristics were demonstrated in AL-CA and HCM patients by 3D-STE., (Copyright © 2017 Sociedade Portuguesa de Cardiologia.

- Abstract
Systemic amyloidosis is a rare disease, in which the heart involvement is rather frequent and determines survival remarkably. Regarding the disease and organ involvement, new diagnostic procedures help to establish the diagnosis and to start the adequate treatment as soon as possible. Cardiac involvement is more likely to be characterised by monoclonal immunglobulin free light chain (AL amyloidosis) type and transthyretin type. In case of AL amyloidosis, heart involvement can lead to serious consequences. Biomarker assessments for cardiac function are important to determine disease severity at the beginning and to measure response to the treatment. In case of amyloidosis, the incidence of the heart involvement grows with age. The prevalence is not known exactly, but probably there are more cases than recognised. The authors present the clinical signs and diagnostic methods, emphasizing the importance of the cardiac examination methods. Orv Hetil. 2017; 158(46): 1811-1818.

- Abstract
Introduction: Extranodal natural killer/T (NK/T) cell lymphoma, nasal type (ENKTL) represents a rare subtype of T-cell lymphomas with aggressive clinical behavior according to WHO 2016 classification., Aim: ENKTL has distinctive geographic distribution with higher incidence in Asia and Latin America (10% of all non-Hodgkin lymphoma cases), than in Europe and North America (<1%). ENKTL tipically origins from nasopharynx and upper aerodigestive tract. Anthracycline-based chemotherapy regimens are largely ineffective in the treatment of ENKTL., Method: Our aims were to evaluate the incidence and treatment strategies of ENKTL patients in Hungarian Haematological Centres between 2003 and 2015. Altogether 20 patients with ENKTL were treated in the 4 haematological hospitals (male:female ratio 12:8, with median 49.5 years of age)., Results: Ten patients had localized (stage I-II) disease at the time of the diagnosis. Seventeen patients were treated with chemotherapy (11/CHOP, CHOP-like, 2/HyperCVAD, 1/ProMACECytaBom, 1/SMILE, 2/others), which was completed with involved-field radiation therapy (IFRT) (40-46 Gy) in 6 cases were used. After first-line therapy 9 patients achieved complete remission (CR), 3 patients had partial remission (PR), 3 patients had progressive disease (PD), and 2 patients had stable disease (SD). Median follow-up was 32 (3-113) months. Five patients received second-line therapy for progressive or recurrent disease [2/DHAP, 1/VIM, 1/HyperCVAD, 1/ProMACECytaBom]. None of the patients achieved CR after second-line therapy. Two patients have undergone autologous hematopoietic stem cell transplantation (HSCT) after the first CR., Conclusion: ENKTL treatment is more effective with nonanthracycline-containing regimens. L-asparaginase containing chemotherapy and concurrent or sequential chemo-radiotherapy improves survival and CR rates. Orv Hetil. 2017; 158(41): 1635-1641.

- Abstract
Chronic lymphoid leukaemia (CLL) has a heterogeneous clinical course depending on many clinical and molecular prognostic markers, which play an important role in the selection of the best treatment option. So far, TP53 disruption is the key prognostic and predictive factor assisting treatment decisions, especially in the era of novel therapies. Asymptomatic patients in early stages of the disease will still benefit from watchful waiting. In the frontline setting, chemoimmunotherapy is still the standard care in the majority of standard risk CLL patients. New classes of drugs like kinase inhibitors and BCL-2 inhibitors (ibrutinib, idelalisib and venetoclax) are the treatment of choice in CLL patients with relapsed/refractory disease, with the exception of high risk disease, where the optimal treatment is frontline ibrutinib monotherapy. In the near future, integrating next generation sequencing into the routine diagnostics would help the development of individual CLL patient management and to choose an optimal treatment strategy.

- Abstract
Background and Aim of the Study: Cardiac amyloidosis (CA) is a rare condition characterized by the extracellular deposition of amyloidogenic proteins in the heart. The aim of the present study was to compare the size and function of the mitral annulus (MA) between CA patients and age- and gender-matched controls, using three-dimensional speckle-tracking echocardiography (3-D STE)., Methods: The study included 17 patients (mean age 64.2 ± 9.8 years) with CA, whose results were compared to 26 age- and gender-matched healthy controls (mean age 59.0 ± 8.2 years). Complete two-dimensional (2-D) Doppler echocardiography and 3-D STE were performed in all cases., Results: Significantly enlarged end-diastolic and end-systolic MA diameters (3.09 ± 0.56 cm versus 2.70 ± 0.37 cm, p = 0.01 and 2.71 ± 0.68 cm versus 1.87 ± 0.31 cm, p <0.001) and MA area (11.22 ± 3.56 cm2 versus 8.60 ± 1.92 cm2, p = 0.004 and 8.57 ± 3.35 cm2 versus 4.55 ± 1.05 cm2, p <0.001) were demonstrated in CA. MA fractional area change (24.10 ± 13.97% versus 46.06 ± 14.37%, p <0.001) and MA fractional shortening (12.92 ± 9.55% versus 30.98 ± 11.65%, p <0.001) were also impaired in CA patients as compared to matched controls., Conclusions: CA is associated with MA enlargement and functional impairment represented by MA fractional shortening and MA fractional area change, as assessed using 3-D STE.

- Abstract
Secondary myocardial involvement by diffuse large B-cell lymphoma is a rare occurrence. Left ventricular (LV) twist is considered an essential part of LV function. In normal circumstances LV twist results from the movement of two orthogonally oriented muscular bands of a helical myocardial structure with consequent clockwise rotation of the base and counterclockwise rotation of the apex. Three-dimensional (3D) speckle-tracking echocardiography (3DSTE) has been found to be feasible for non-invasive 3D quantification of LV wall motion and rotational mechanics. The present report aimed to assess LV twisting motion in a patient with diffuse large B-cell lymphoma with positron emission tomography/computer tomography-proven cardiac involvement by 3DSTE. During 3DSTE, reduction in some segmental radial, longitudinal, circumferential, area and 3D LV strains were found. Apical and basal LV rotations were found to be in the same counterclockwise direction, confirming near absence of LV twist - so-called rigid body rotation., (Copyright © 2016 Sociedade Portuguesa de Cardiologia.

- Abstract
Because of the widespread use of immunosuppressive drugs, CMV infection is one of the most important causes of morbidity and mortality in patients with haematological malignancies worldwide. The aim of the study was to retrospectively analyse the epidemiology of CMV infection in haematological patients. Between 2008 and 2014, 1238 quantitative CMV DNA detections from plasma specimens were performed. These specimens were collected from 271 patients with haematological malignancy. Patients were grouped on the basis of underlying diseases (lymphoid and myeloid malignancies and other haematological diseases). In the lymphoid and myeloid groups, we distinguished ASCT and non-ASCT groups. During the studied period, the majority of examined patients (82.6 %) were treated with lymphoproliferative disease. A total of 126 (46.5 %) patients underwent ASCT, while 145 (53.5 %) did not have stem cell transplantation. A total of 118 (9.5 %) of 1238 plasma specimens proved to be positive for CMV DNA; these specimens were collected from 66 (24.4 %) patients. Twenty-four (16.6 %) of 145 non-ASCT patients had CMV PCR positive specimens. Among non-ASCT patients with positive CMV PCR results, 10 patients were asymptomatic, 14 had symptomatic reactivation, while 2 had CMV disease. In the ASCT group, 42 (33.3 %) patients had CMV PCR positive samples. CMV reactivation was asymptomatic in 34 (81 %) cases, and 8 (19 %) patients had symptomatic reactivation. In the non-ASCT group, the rate of CMV infection is low. In the ASCT group, the prevalence of CMV infection was higher than in the non-ASCT group, but the majority of CMV infection was asymptomatic and only small number of patients had symptomatic reactivation. Thus, our results also showed that the use of routine CMV DNA monitoring is not necessary in patients with haematological malignancies not receiving fludarabine-containing regimen or alemtuzumab, in spite of this to decrease the mortality we have to consider the use of molecular tests in case of suspected infectious conditions.

- Abstract
Polycythaemia vera (PV), a condition characterized by blood hyperviscosity due to the expansion of the erythrocyte mass is the most common entity among all Philadelphia chromosome-negative myeloproliferative neoplasms. Arterial and venous thrombotic events are leading determinants of morbidity and mortality but impairment of quality of life due to vasomotor symptoms (erythromelalgia, pruritus) and disease-associated symptoms (tiredness, fatigue, pruritus, night sweats, vision problems, headache, concentration loss, abdominal discomfort, early satiety, fever, weight loss) are also present. The review of polycythaemia vera is actual as the updated WHO 2016 classification of myeloid neoplasms has changed the diagnostic criteria and a new second-line treatment option - JAK1/JAK2 inhibitor ruxolitinib - has been approved for patients who had an inadequate response to or are intolerant of hydroxyurea, which represents a breakthrough in the treatment of this patient population.

- Abstract
Primary myelofibrosis is one of the Philadelphia negative chronic myeloproliferative neoplasms. It is a rare disease featured by cytopenias and hepatosplenomegaly. Although the etiology of the disease is still unknown, our knowledge about its pathology and prognosis has been improving in the last few years. Furthermore, the JAK2 inhibitor ruxolitinib has become available in Hungary since 2015. Beside its high efficacy in spleen volume and in reduction of myelofibrosis-associated symptoms, this novel therapy also exerts a disease-modifying effect and, therefore, ruxolitinib may improve the life expectancy too. Treatment approach of myelofibrosis has been changed these years, which gives a reason for this summary. Orv. Hetil., 2016, 157(39), 1547-1556.

- Abstract
Introduction: Because of the use of chemo-immunotherapeutic drugs, cytomegalovirus infection is one of the most important infectious complications among patients with haematological malignancies., Aim: The aim of the authors was to detect cytomegalovirus infection and reactivation using quantitative real-time polymerase chain reaction., Method: Between 2012 and 2014, the authors retrospectively analysed 96 patient's medical history hospitalised in haematology Unit. Patients were grouped on the basis of their underlying diseases (lymphoprolipherative malignancies, acute leukaemias), and the following groups were created: autologous stem cell transplanted and non-transplanted groups., Results: Eighty-three patients were treated with lymphoprolipherative disorders, and 63 (76%) of them underwent autologous stem cell transplantation. Out of the 604 plasma specimens 46 (7.6%) were positive for the cytomegalovirus desoxyribonucleic acid collected from 25 patients [6 non-transplanted (18%) and 19 from the transplanted group (30.2%)]. The frequency of cytomegalovirus positivity was doubled in the transplanted patient group, however, reactivation was asymptomatic in 68% of the cases., Conclusions: The routine use of cytomegalovirus monitoring is not necessary in this patient group. In case of suspected cytomegalovirus infection, molecular tests allow early preemptive antiviral therapy, which may decrease the mortality attributed to cytomegalovirus infection. Orv.

- Abstract
Objective: Detailed analyses of clinical characteristics of myocardial infarction (MI) as an essential thrombocythemia (ET)- and polycythemia vera (PV)-related complication have been so far presented mostly as case reports. Therefore, the aim of this retrospective analysis was to evaluate the main cardiological and hematological characteristics for better understanding myocardial complications in ET/PV., Methods: A retrospective analysis was carried out involving 263 patients diagnosed with ET or PV (155/108) between 1998 and 2014. Fourteen patients suffered MI during the hematological follow-up. Their clinical characteristics were compared to 162 patients (97 ET and 65 PV patients) who did not exhibit any major thrombotic complications (MI, stroke/transient ischemic attack, and venous events) before or after hematological diagnosis of ET/PV., Results: Fourteen MI events occurred among the 263 patients (5.3%). Vascular risk factors were found in 92.9% (13/14) of analyzed cases. In all, 71.4% of the MI complications developed within 12 months after the diagnosis of ET/PV. The coronary angiography findings revealed ST-elevation MI in four cases and non-ST-elevation MI in 10. Significant stenosis of coronary arteries requiring percutaneous coronary intervention with a stent implantation was present in seven cases, while three had complex stenoses or previous grafts/stents. All of them had undergone coronary artery bypass graft operations., Conclusion: The results of the present study suggest that early detection and consideration of individual management of vascular risk factors in ET/PV patients are also important. Furthermore, a better theoretic understanding of platelet activation and role of leukocytes in myeloproliferative neoplasm-related thrombosis could open new perspectives in thrombosis prediction and prevention.

- Abstract
Introduction: The present study was designed to compare three-dimensional speckle tracking echocardiography (3DSTE)-derived left atrial (LA) volumetric, volume-based functional and strain parameters between patients with hypereosinophilic syndrome (HES) and matched controls., Methods: A total of 10 HES patients and 19 age- and gender-matched healthy controls were included in the study. Complete two-dimensional Doppler echocardiography and 3DSTE were performed in all HES cases and controls., Results: Significantly increased maximum (72.9±38.8 ml vs. 45.6±15.5 ml, p=0.01) and minimum (46.3±33.3 ml vs. 26.0±15.0 ml, p=0.03) LA volumes and LA volume before atrial contraction (62.0±36.0 ml vs. 36.5±16.6 ml, p=0.01) were found in HES patients compared to controls. Both peak global (18.3±6.7% vs. 25.6±9.0%, p=0.03) and mean segmental (22.2±6.0% vs. 31.0±12.1%, p=0.04) circumferential strains were significantly reduced in HES patients, suggesting decreased LA reservoir function., Conclusion: Increased LA volumes can be demonstrated in HES patients, accompanied by reduced LA peak circumferential strain as assessed by 3DSTE, suggesting LA remodeling., (Copyright © 2016 Sociedade Portuguesa de Cardiologia.

- Abstract
Systemic mastocytosis (SM) is a rare chronic myeloproliferative neoplasm with only limited epidemiologic data published so far. We aimed to analyze the clinical and molecular diagnostic features, and the prognosis and cumulative incidence of SM cases in a cohort of south-eastern Hungarian patients of 13 year follow up. In the period 2001-2013, 35 consecutive SM cases were diagnosed in our regional centre. Immunophenotype, KIT D816V mutation frequency and clinical characteristics, and the prognosis impact of clinical subtypes were tested and compared with published data. Indolent SM (ISM) was diagnosed in 14 patients, SM with an associated clonal hematologic non-mast cell lineage disease (SM-AHNMD) in 15 patients and aggressive SM (ASM) in 6 patients. The KIT D816V mutation was found in 11/14 (78%) of the ISM cases, in 12/15 (80%) of the SM-AHNMD cases and in 5/6 (83%) of the ASM cases. The life expectancy of ISM patients was better, whereas the SM-AHNMD and ASM groups exhibited a reduced median survival. The cumulative incidence for 13 year of the SM was 0.27/10,000. We detected lower 13 year cumulative SM incidence than of published epidemiologic data due to in our analyses involved only those patients who had bone marrow biopsy and histopathologically confirmed SM. This clinical overview clearly showed that the clinical characteristics differ between ISM (UP, anaphylaxis and osteoporosis) and SM-AHNMD/ASM (cytopenia, eosinophilia and splenomegaly).

- Abstract
Cardiac amyloidosis (CA) is an infiltrative disease primarily caused by extracellular tissue deposition of amyloid fibrils in the myocardial interstitium. The aim of the present study was to examine left ventricular (LV) rotational mechanics in biopsy-proven CA by three-dimensional (3D) speckle-tracking echocardiography (STE). Ten patients (65.3±11.5 years, 6 males) with CA entered the study. The mean basal LV rotations were 0.3±3.8°, while mean apical LV rotations proved to be 7.0±3.3°. LV basal and apical rotations were in the same counterclockwise direction in 6 out of 10 CA patients demonstrating near absence of LV twist [LV rigid body rotation (RBR)]. Apico-basal difference was near 3 or less degrees in three patients with LV-RBR, and 6-10 degrees in the other three subjects with LV-RBR. One another patient showed normal rotational mechanics, while two patients had significant hyporotations and one had significant hyperrotations in normal directions. To conclude with, different patterns of LV rotational mechanics could be demonstrated in CA. LV RBR, the near absence of LV twist seems to be a frequent phenomenon in CA.

- Abstract
From year to year, it is important to get an overview of the occurrence of causative agents in febrile neutropenic patients to determine the empiric treatment. Thus our aims were to evaluate a four-year period regarding the prevalence of bloodstream infections and the most important causative agents. During this period, 1,361 patients were treated in our hematology ward because of various hematological disorders. 812 febrile episodes were recorded in 469 patients. At that time, 3,714 blood culture (BC) bottles were sent for microbiological investigations, 759 of them gave positive signal. From the majority of positive blood culture bottles (67.1%), Gram-positive bacteria, mainly coagulase-negative staphylococci (CNS), were grown. Gram-negative bacteria were isolated from 32.9% of the positive blood culture bottles, in these cases the leading pathogen was Escherichia coli. The high prevalence of CNS was attributed to mainly contamination, while lower positivity rate for Gram-negative bacteria was associated with the use of broad-spectrum empiric antibiotic treatment.

- Abstract
Myocyte enhancer binding factor 2 B (MEF2B) is a member of the evolutionary conserved transcription family MEF2. MEF2B has been shown to directly control biological activity of the B cell lymphoma 6 (BCL6) gene in germinal center (GC) B cells. To validate MEF2B as an immunohistochemical marker, we studied a large consecutive series of hyperplastic lymphoid tissues (n = 38) and malignant lymphoproliferative conditions (n = 471), including all major categories of B and T cell neoplasms. In hyperplastic lymphoid tissues, MEF2B staining revealed intense and crisp nuclear expression confined to GC B cells. Unlike BCL6, MEF2B was not detected in follicular T cells. In addition, weak nuclear staining of plasma cells was noted. MEF2B staining labeled neoplastic cells of follicular lymphoma both in common and variant cases as well as in bone marrow biopsies with high sensitivity, while it was almost consistently negative in marginal zone lymphoma. Consistent MEF2B expression was found in Burkitt lymphoma and nodular lymphocyte predominant Hodgkin lymphoma as well as in the large majority of cases of mantle cell lymphoma and diffuse large cell B cell lymphoma. MEF2B protein expression showed a statistically significant association with that of BCL6 in cases of diffuse large B cell lymphoma, not otherwise specified. We conclude that MEF2B is a valuable marker of normal GC B cells, potentially useful in differential diagnosis of small B cell lymphomas.

- Abstract
Thrombo-haemorrhagic events are the main cause of morbidity and mortality in essential thrombocythemia. The aim of this study was to estimate the incidence of thrombotic events and the impact of the JAK2V617F, MPL (W515L, W515K, W515R, W515A and S505N) and CALR (type-1, type-2) mutations on 101 essential thrombocythaemia patients (72 females and 29 males with a mean age of 61 years) diagnosed in a Southern Hungarian regional academic centre. The incidence of major thrombosis was 13.86 %. Sixty percent of the patients carried the JAK2V617F mutation. The MPL mutations were analysed by sequencing and the W515L was the only one we could identify with an incidence of 3.96 %. Type-2 CALR mutation could be identified in 3 cases among the patients who had JAK2/MPL-unmutated ET. Statistical analyses revealed that the JAK2V617F mutation was associated with significantly increased levels of platelet (p = 0.042), haemoglobin (p = 0.000), red blood cell (p = 0.000) and haematocrit (p = 0.000) and hepatomegaly (p = 0.045) at diagnosis compared to JAK2V617F negative counterparts, however there was no significant association between the JAK2V617F mutation status (relative risk: 1.297, 95 % CI 0.395-4.258; p = 0.668) and subsequent thrombotic complications. The impact of JAK2V617F, MPL W515L and CALR mutations on the clinical findings at the diagnosis of ET was obvious, but their statistically significant role in the prediction of thrombotic events could not be proven in this study. Our results indirectly support the concept that, besides the quantitative and qualitative changes in the platelets, the mechanisms leading to thrombosis are more complex and multifactorial.

- Abstract
Introduction: The FIP1L1-PDGFR alpha-positive, hypereosinophilic syndrome (HES) is a new category of hematological entities. Various clinical symptoms may occur, with no specific characteristics in either the clinical picture or the neuroimaging findings, and this may give rise to a diagnostic dilemma. A report on a long follow-up period (10 years) in a case of HES that presented with neuropsychiatric symptoms appears to be unique. Besides the complexity of the diagnostic process, the successful treatment is discussed., Case Report: The HES was diagnosed in a male patient at the age of 33 years, with involvement of the central nervous system and the myocardium. After the onset of the clinical signs, the MRI indicated bilateral cerebral and cerebellar cortico-subcortical lesions involving the watershed areas, mainly in the parieto-occipital regions. High-dose intravenous steroid (methylprednisolone 500 mg/day) alleviated the neurological symptoms within a few weeks, and the administration of imatinib (200 mg/day) resulted in an impressive regression of the hypereosinophilia and splenomegaly within 6 weeks. During the follow-up, the patient has continued to receive imatinib. The molecular remission has persisted, no new complaints have developed and the condition of the patient has remained stable., Conclusion: The timely recognition of the HES and identification of the disease subtype which led to the administration of imatinib may be the key to successful treatment. The long stable follow-up period gives rise to a new dilemma in the treatment of the HES in these special cases: for how long should a patient receive a tyrosine kinase inhibitor, and may the treatment be suspended?

- Abstract
Introduction: Thrombo-haemorrhagic complications contribute to both morbidity and mortality in patients with essential thrombocythaemia., Aim: The aim of the authors was to estimate the incidence of thrombotic events and to examine the clinical utility of IPSET thrombosis risk evaluation score against conventional two-categorical (low and high) risk assessment., Method: A retrospective analysis was carried out on 155 patients with essential thrombocythaemia (106 females; median age, 61 years) in a period between 1999 and 2014., Results: The analysis revealed 55 (35.5%) major thrombotic events before and 25 (16.1%) major thrombotic complications after establishment of the haematologic diagnosis. Significant differences were observed in thrombosis-free survival between the different IPSET groups (p = 0.002)., Conclusions: The IPSET model was first examined in this cohort of patients with essential thrombocythaemia diagnosed in a single Hungarian haematologic centre. The results suggest that this score may provide more information than the conventional thrombosis risk assessment.
