Abstract
BACKGROUND Increasing numbers of unrelated hematopoietic stem cell grafts are transported internationally and evaluated concurrently in different laboratories. The graft quality assessment using the CD34(+) enumeration could be influenced by inter-laboratory variability. METHODS We retrospectively analyzed the content of CD34(+) cells in 154 consecutive collections being performed in different transplant centers during two periods (2003-2004, 2007-2010). All samples were tested twice in our own and partner laboratories. CD34(+) percentage and absolute number were compared. RESULTS The percentage and the total CD34(+) content correlated well in both observed periods (CD34(+)%: r=0.899 and r=0.922; CD34(+)×10(8)/kg: r=0.966 and r=0.880; p<0.0001). Median CD34(+) percentages obtained in our centre in comparison with other laboratories were 0.54% vs. 0.46% in 2003-2004 and 0.69% vs. 0.70% in 2007-2010 period. The degree of laboratory compliance was affected by the laboratory identity. CD34(+) percentage reported by one laboratory and CD34(+)×10(8)/kg reported by three from twelve laboratories lacked statistically significant correlation with our own data. CONCLUSIONS The study documented that results of CD34(+) cell dose assessment of the same grafts reported by different transplant centers are comparable. The graft quality data and the CD34(+) enumeration possess a limited level of inter-laboratory variability.

Abstract
BACKGROUND Angioimmunoblastic T-lymphoma (AITL) is a poor prognosis malignancy. Because of relatively rare incidence and lack of publications in Czech, we decided to share our experience. PATIENTS AND METHODS Retrospective analysis of newly diagnosed AITL patients treated at our institution between 1/2000-12/2010. RESULTS Twelve patients with median age of 64 (43-82) years were analysed. Two patients over 80 years were treated with corticosteroids. Ten patients were treated with 6 cycles of CHOP-21 chemotherapy resulting in: 2/10 (20%) stable disease, 5/10 (50%) partial remission and 3/10 (30%) complete remission. The median EFS and OS of chemotherapy-treated patients were 8 and 10 months, resp. The EFS and OS were both significantly longer in patients who achieved complete remission within the first line of CHOP or autologous stem cells transplantation therapy: 43 vs 6 (p = 0.0052) and 46 vs 6 months (p = 0.0023), respectively. It was not possible to perform autologous transplantation in 4/7 (57%) patients in need for further reduction of the disease because of poor performance status or early progression of lymphoma and death during salvage chemotherapy. CONCLUSION AITL is a poor prognosis malignancy with a very high risk of early relapse after CHOP induction chemotherapy. In fit patients, autologous transplantation should be performed immediately after induction chemotherapy; information about availability of stem cells donor, both in the family or any available register, should be found during the induction treatment.

Abstract
BACKGROUND Donor cell leukemia (DCL) is a relatively rare but well documented complication of hematopoietic stem cell transplantation. So far, publications described only DCL arising de novo in the recipient. OBSERVATION In this study, we describe a case of chronic lymphocytic leukemia (B-CLL) developing in a volunteer unrelated donor from the Czech National Marrow Donors Registry (CNMDR) several years after donation. From archival DNA sample, we have retrospectively found that subclinical CLL clone was already present at the time of donation but early death of recipient prevented eventual development of DCL. This case documents well the long period between detection of B-CLL clone and full development of clinical-laboratory symptomatology. The medical and ethical questions posed by an isolated case of detection of hematological malignancy present either only in the donor or only in the recipient are discussed. CONCLUSION The case demonstrates the increasing risk of development of various forms of DCL and thus highlights the need for long-term monitoring of stem cell donor, not only in terms of health of donor but also in terms of potential risks for the recipient.

Abstract
BACKGROUNDS Granulopoesis colony-stimulating factor filgrastim is used to mobilize peripheral stem cells but there are concerns regarding an elevated risk of haematological malignancies. We analyzed the incidence of malignancies and the system of haematopoietic stem cells donor surveillance. PATIENTS AND METHODS prospective observation of sibling donors of the Haemato-Oncology Department University Hospital in Plzen (Pilsen) and of unrelated donors of the Czech National Marrow Donors Registry (CNMDR) in 2001-2010. RESULTS No malignancy was observed in a group of 344 unrelated CNMDR donors, providing 753 person-years; one case of chronic lymphocytic leukaemia manifested 6 years after bone marrow donation, with leukaemia clone retrospectively detected by DNA analysis in blood samples taken prior to the marrow donation. Acute myeloid leukaemia, non-Hodgkin lymphoma, renal and colorectal carcinoma were observed in a group of 84 peripheral stem cells sibling donors, providing 337 person-years observation. The respective incidence of the two haematologic malignancies was 593 cases and the expected incidence rate was 143 per 100,000. The sibling (related) donors age was significantly higher: 48 (16-75) vs. 31 (20-42) years, (p<0.0001). Significantly more lost-to-follow-up donors were among the related donors (32% vs. 3%, p<0.0001), even though active surveillance system was implemented. CONCLUSION The development of malignancies in hematopoietic stem cells donors can naturally be expected. Related (sibling) donors are at higher risk because of their generally older age, and higher susceptibility to haematological malignancies developed within the family. The contribution of filgrastim exposure needs to be further investigated. The follow-up cooperation with related (sibling) donors is limited.

Abstract
BACKGROUNDS This retrospective study evaluated treatment outcomes in patients undergoing autologous stem cell transplantation (ASCT) for relapsed/refractory Hodgkin lymphoma (HL). PATIENTS AND METHODS Overall, 194 HL patients treated with ASCT between 2000 and 2009 were analyzed. Survival was calculated using Kaplan-Meier method and differences in survival between subgroups with log-rank test. RESULTS Best responses observed after ASCT: 124 complete and 35 partial remissions, 2 patients with stable disease and 33 relapses/progressions. During a median follow-up of 44 months, seventy patients after ASCT progressed/relapsed. Thirty-seven patients received salvage chemotherapy only with or without radiotherapy, 25 underwent allogeneic stem cell transplantation (SCT), 4 the second ASCT and 4 refused treatment. 5-year overall survival after ASCT was 71% and progression-free survival 54%. Median survival of the 70 patients relapsing after ASCT was 16.9 months. Median survival in patients after allogeneic SCT was 31.8 months and 12.4 months in patients treated with other modalities (p = 0.21). Overall mortality was 26.3% (51/194 patients): 13.4% progressions/relapses of HL and 12.9% non-relapse mortality. CONCLUSION Efficacy of ASCT was confirmed in 54% progression-free survivors. Median survival after ASCT failure is relatively short. There is a slightly longer overall survival after allogeneic SCT, although not statistically significant when compared to other approaches.

Abstract
Despite the independent segregation of genes encoding killer immunoglobulin-like receptor (KIR) and human leukocyte antigen (HLA), there is some evidence of some kind of co-evolution. Therefore, one could expect reduced KIR diversity within the HLA restricted population. A total of 41 unrelated individuals homozygous for ancestral HLA haplotype AH8.1 (HLA-A*0101-Cw*0701-B*0801-DRB1*0301-DQB1*0201) were genotyped for KIRs. Over all, 14 different genotypes were identified. The KIR genes and genotypes repertoire generally mirror the published frequencies in Caucasians. Except for KIR2DS4, all activating genes presented frequencies below 50%. KIR2DS5 was the least frequent among activating genes (17%), whereas KIR2DL5 (37%) among inhibitory ones. The most frequent (39%) was AA genotype. Twenty-two individuals (54%) had a copy of KIR haplotypes A and B (AB genotype), whereas three (7%) were homozygous for B (BB genotype). Nine of fourteen reported genotypes occurred only in one individual. Five genotypes were reported in less than twenty individuals worldwide and one genotype was reported so far only once. Conversely, the three most frequent genotypes account for 68% of all detected genotypes. The results show the unrestricted KIR diversity in this HLA uniform group and support the fact that the driving force for KIR evolution is not exclusively a major histocompatibility complex.

Abstract
Various polymorphisms of non-HLA genes have recently been investigated as candidate risk factors in allogeneic haematopoietic SCT (aHSCT). Our study aimed at exploring possible associations of IL6 and CCL2 single nucleotide polymorphisms (SNP) with aHSCT outcome. A total of 166 HLA-identical aHSCT pairs recruited in were genotyped for IL6 -174 G/C, IL6 -597 G/A, CCL2 -2518 A/G and CCL2 -2076 A/T SNPs by PCR with sequence-specific primers (PCR-SSP). The association between IL6 -174 GG genotype and increased risk of acute GVHD was found in whole study group (P=0.03) and in the subgroup of related aHSCT (P=0.01), association between IL6 -597 GG genotype and the occurrence of acute GVHD was detected only in the related aHSCT pairs (P=0.02). Furthermore, reduction in OS was revealed among recipients possessing IL6 -174(*)G allele in the group of related aHSCT pairs (P=0.04). Presence of CCL2 -2076 TT genotype was associated with decrease of OS (P=0.04) and increase of TRM (P=0.02) in patients transplanted by related donor. These results, in the context of previous findings, suggest that IL6 gene polymorphisms may be associated with aHSCT outcome, particularly in patients transplanted from a related donor.

Abstract
Both preemptive therapy and universal prophylaxis are used to prevent cytomegalovirus (CMV) disease after transplantation. Randomized trials comparing both strategies are sparse. Renal transplant recipients at risk for CMV (D+/R-, D+/R+, D-/R+) were randomized to 3-month prophylaxis with valacyclovir (2 g q.i.d., n = 34) or preemptive therapy with valganciclovir (900 mg b.i.d. for a minimum of 14 days, n = 36) for significant CMV DNAemia (>/=2000 copies/mL by quantitative PCR in whole blood) assessed weekly for 16 weeks and at 5, 6, 9 and 12 months. The 12-month incidence of CMV DNAemia was higher in the preemptive group (92% vs. 59%, p < 0.001) while the incidence of CMV disease was not different (6% vs. 9%, p = 0.567). The onset of CMV DNAemia was delayed in the valacyclovir group (37 +/- 22 vs. 187 +/- 110 days, p < 0.001). Significantly higher rate of biopsy-proven acute rejection during 12 months was observed in the preemptive group (36% vs. 15%, p = 0.034). The average CMV-associated costs per patient were $5525 and $2629 in preemptive therapy and valacyclovir, respectively (p < 0.001). However, assuming the cost of $60 per PCR test, there was no difference in overall costs. In conclusion, preemptive valganciclovir therapy and valacyclovir prophylaxis are equally effective in the prevention of CMV disease after renal transplantation.

Abstract
Autologous peripheral blood stem cell transplantation is performed in an increasing number of chronic lymphocytic leukaemia (CLL) patients who are in the first remission following fludarabine treatment. There are contradictory data about the adverse impact of fludarabine on stem cell harvest. We analysed retrospectively mobilization results in 56 poor-risk CLL patients (median age: 56 years) who underwent first-line treatment with fludarabine and cyclophosphamide. The mobilization, consisting of cyclophosphamide 3 g/m(2) and granulocyte colony-stimulating factor (G-CSF) 10 microg/kg per day, was performed with a median of 77 days following the last fludarabine course. The target yield was >or=2.0x10(6) CD34+ cells/kg. The procedure was successful in 23 (41%) patients. A median of 3.3x10(6) CD34+ cells/kg was collected per patient. The successful mobilization was associated with a longer interval from the last chemotherapy (>2 months). The mobilization result was not influenced by the number of fludarabine cycles. No correlation was found in other parameters such as disease stage at diagnosis, disease status at stimulation or age. The poorly mobilized patients had significantly lower prestimulation blood counts (platelets, WBC and haemoglobin). Our data show that fludarabine does not generally prevent the stem cell mobilization; nevertheless, mechanisms related to the impact of fludarabine on stem cell harvest must be further investigated.

Abstract
We have tried to make use of the opportunity of repeated observations through the analysis of the recorded movements of the phonating vocal folds by means of the phonating vocal folds through indirect videolaryngostroboscopic technique. The results of our investigation correspond, among others, with Hála and Sovák's diagrammatic description of continual and gradual changes in the vibration of the vocal folds in an uninterrupted sequence of tones of the human voice. In the initial chapter mention has been made of Hála and Honty's works and of Pressmann's work dealing with the described behaviour of the glottis when phonating high-pitched tones. The conclusions analogous to our findings have also been described by means of stereoscopically measuring the length of the phonating vocal folds. In conclusion, by measuring the distances between the anterior commissure and the junction between the membranous part of the vocal fold and vocal process of the arytenoid and the anterior commissure to the posterior nodal point of the vibrating part of the vocal folds we have verified the correctness of the findings published by Czermak, Hála and Honty, Pressmann, and Sovák, who pointed out the phenomenon of the shortening of the front vibrating part of the vocal folds in phonating high-pitched tones of the human voice.

Abstract
UNLABELLED The objective of the work was to evaluate the frequency and time of incidence of cytomegaloviral (CMV) infection and disease in patients after allogeneic bone marrow transplantation (BMT). One hundred patients were followed up (70 with a related and 30 with an unrelated donor), who had transplantations during the period between XI/1996-XI/2000. METHODS USED nested-PCR (MIE-gene) and antigenaemia (antigen pp65). Active CMV infection was proved in antigenaemia > or = 5 positive cells or in two consecutive positive PCR. The CMV syndrome was assessed in confirmed CMV infection and otherwise inexplicable febrile conditions and/or a drop of haemogram values. For the diagnosis of CMV pneumonia the clinical picture was needed, evidence of active CMV infection and on the X-ray of the lungs interstitial pneumonia. In 33 patients both methods were used, in 67 only PCR. The first positive test appeared 6-321 days after BMT (median +/- 49 days). CMV infection was proved in 44% cases, CMV syndrome in 30% and CMV pneumonia in 4%. In patients with a related donor CMV infection was found in 34.3%, CMV syndrome in 22.9%, CMV pneumonia in 1.4%. After unrelated donor BMT CMV infection was recorded in 66.7%, CMV syndrome in 46.7% and CMV pneumonia in 10% patients. Two patients died from CMV pneumonia. CMV pneumonia was diagnosed 57-115 days after BMT (median +/- 68 days. The risk of CMV infection is high in both groups of patients, in particular in patients after unrelated donor BMT (66.7%). As far as the development of CMV pneumonia was concerned, the mortality in the authors' group was 50%.

Abstract
Herein we describe 7 cases of posttransplantation lymphoproliferative disease (PTLD), 5 in men and 2 in women (aged from 25 to 62 years), occurring from 4 months to 12 years (mean, 7 years) after transplantation. Our patients were recipients of kidney, kidney and pancreas, heart, and autologous peripheral haematopoetic stem cells. Four cases were diagnosed as monomorphic and three as polymorphic type of PTLD according to the WHO classification. Monoclonal immunoglobuline heavy chain gene rearrangement was detected in two monomorphic lesions and one polymorphic lesion by polymerase chain reaction (PCR). In the two cases of polymorphic and the one case of monomorphic PTLD, the presence of EBV was visualised by immunohistochemical staining of some transformed lymphoid cells for latent membrane protein (LMP) of EBV. The presence of type A EBV was demonstrated by PCR. The patients were treated by reduction or discontinuation of immunosuppression and by chemotherapy. In 2 cases, a part of the organ affected by lymphoma (sigmoid colon and pancreas) was surgically resected. Four patients died of causes related to PTLD (2 to 15 months after the diagnosis), mainly of infectious complications. Two other patients who achieved remission died of unrelated causes. Only the youngest man is alive and in the complete remission 10 months after the diagnosis of PTLD.

Abstract
The authors compare the results of allogenic bone marrow transplantations of relatives in patients with chronic myeloid leukaemia during the initial years of the transplantation programme 1991-1995 (group 1, 15 patients) with results achieved in 1996-1998 (group 2, 30 patients) and evaluate the effect of changes concerning supportive treatment and new diagnostic methods. The age median of group 1 was 35 years, the median age of group 2 46 years. In other parameters the groups were comparable. In 1991-1995 a high transplantation mortality by the 100th day was recorded (40% as compared with 17%) and a higher incidence of stage III and IV of the acute reaction of the graft against the host (GVHD) in group 1 (20% vs. 6%). In group 2 there was a higher transplantation mortality after day 100 associated with a more frequent chronic GVHD (0% vs. 16.5%). The total survival is insignificantly better in group 2 (60% in group 1 survive with a median of 58 months follow up and 67% of group 2 with a median follow up of 33 months). Group 2 comprises however older patients. In the improved early transplantation mortality participated new methods, a change of the posttransplantation immunosuppression, experience with care of transplanted patients and better collaboration with other medical disciplines. The authors did not observe a substantial effect of changes in the basic supportive treatment on results of transplantation. Late transplantation mortality associated in particular with a higher incidence of chronic GVHD could be in the authors' opinion reduced by longer administration of immunosuppression after transplantation, in particular in older patients.

Abstract
Increasing age has been reported to be associated with worse outcome and higher occurrence of complication after allogeneic bone marrow transplantation. We analysed a cohort of 39 patients between the ages of 45 and 57 (median 49 years) with different hematologic malignancies who had undergone BMT in our institution over the preceding 4 years. Pretransplant conditioning consisted of Bu/CY2, GVHD prophylaxis of a combination of cyclosporine and "short" methotrexate. At present 54% of patients remain alive (with a median follow-up 44 months), the probability of survival at 5 years is 53% (5-year DFS 78%). The 5-year survival probability in the control group of younger patients is 53% (P = 0.8003). Main causes of death were GVHD (4 patients, 10%), relapse (5 patients, 13%) and infection (6 patients, 15%). The incidence of acute GVHD grade II-IV was 51% (grade III-IV 0% patients), the incidence of chronic GVHD 49% (limited 18% and extensive 31% patients). Our results suggest that allogeneic BMT can be performed in patients above the age of 45 years with acceptable morbidity and mortality, especially if a family HLA matched donor is available.

Abstract
The investigation of the intoning vocal folds with the help of Cermák's mirror in as early as the 19th century and also their ensuring records by means of a stroboscopic film have discovered the fact that the front vibrating part of the vocal folds becomes shortened in high frequencies. This information has been ignored since about the 60ies of the 20th century. The aim of the present paper is to verify the shortening of the front vibrating part of the vocal folds and to recall this fact. Approximately in two octaves we have measured the virtual images of a video stroboscopic record. Our results are comparable with similar measurement resulting from stroboscopic investigation and confirm the hypothetic role of the ligament layer conus elasticus.
