Abstract
BACKGROUND Mucosal biopsy is the most common sampling technique used to assess microbial communities associated with the intestinal mucosa. Biopsies disrupt the epithelium and can be associated with complications such as bleeding. Biopsies sample a limited area of the mucosa, which can lead to potential sampling bias. In contrast to the mucosal biopsy, the mucosal brush technique is less invasive and provides greater mucosal coverage, and if it can provide equivalent microbial community data, it would be preferable to mucosal biopsies. RESULTS We compared microbial samples collected from the intestinal mucosa using either a cytology brush or mucosal biopsy forceps. We collected paired samples from patients with ulcerative colitis (UC) who had previously undergone colectomy and ileal pouch anal anastomosis (IPAA), and profiled the microbial communities of the samples by sequencing V4-V6 or V4-V5 16S rRNA-encoding gene amplicons. Comparisons of 177 taxa in 16 brush-biopsy sample pairs had a mean R2 of 0.94. We found no taxa that varied significantly between the brush and biopsy samples after adjusting for multiple comparisons (false discovery rate ≤0.05). We also tested the reproducibility of DNA amplification and sequencing in 25 replicate pairs and found negligible variation (mean R2 = 0.99). A qPCR analysis of the two methods showed that the relative yields of bacterial DNA to human DNA were several-fold higher in the brush samples than in the biopsies. CONCLUSIONS Mucosal brushing is preferred to mucosal biopsy for sampling the epithelial-associated microbiota. Although both techniques provide similar assessments of the microbial community composition, the brush sampling method has relatively more bacterial to host DNA, covers a larger surface area, and is less traumatic to the epithelium than the mucosal biopsy.

Abstract
Toxicity related to autologous PBSC infusion is well known and traditionally attributed to the presence of DMSO as cryoprotectant. But despite DMSO depletion, adverse events continue appearing. We have conducted a retrospective study to determine the incidence of adverse events related to the PBSC infusion in a large series of 144 patients. Adverse effects were observed in 67.36% of patients, although most of them were of grade 1 or 2. The adverse events most frequently reported were allergic reactions, followed by general, gastrointestinal and respiratory symptoms. In the univariate analysis, age (P=0.01), the volume infused (P=0.005), the amount of DMSO (P=0.008), the total nucleated cells (P=0.002), the total number of granulocytes (P=0.000001) and clumping (P=0.000001) were associated with the occurrence of adverse events. In the multivariate analysis, two protective factors, age (P=0.05) and sex (P=0.004), and two risk factors, the number of granulocytes, with a relative risk of 1.18 (95% confidence interval, 1.06-1.31) (P=0.002), and clumping, with an relative risk of 1.94 (95% confidence interval, 1.15-3.29) (P=0.013), were identified. The best cutoff point for the prediction of the occurrence of adverse events, with a sensitivity of 47% and specificity of 89%, was 6.065 x 10(9) granulocytes.

Abstract
BACKGROUND PBPC collection in children weighing </=25 kg is hampered by technical and clinical problems related to vascular access, low total blood volume, anticoagulation, side effects, and psychological impact. The aim of this study was to analyze several clinical and technical factors, other than pre-apheresis CD34(+) count, that may affect PBPC collection in these low-weight children. METHODS Data from 88 leukaphereses performed in 45 children were analyzed, including pre-apheresis CD34(+) cell count, COBE Spectra software (version 4.7 versus 6.0), apheresis volume [standard versus large-volume leukapheresis (LVL)] and patient's diagnosis, age, weight and sex. RESULTS The median number of PBPC collected was 6.68 mononuclear cells (MNC)x10(8)/kg (range 2.36-19.05) and 1.69 CD34(+) cellsx10(6)/kg (range 0.08-13.79). Multivariate analysis showed that factors independently associated with the CD34(+) cell yield per apheresis were pre-apheresis CD34(+) cell count (P<0.001), diagnosis (P=0.008) and apheresis volume (P=0.009). Recruitment of CD34(+) cells was also independently affected by the apheresis volume, being higher in the LVL group (P=0.008). DISCUSSION We have demonstrated that, apart from the well-known influence of the pre-apheresis CD34(+) cell count, two other factors have a major impact on the CD34(+) cell yield: patient's diagnosis and apheresis volume. In addition, taking into account that side effects were mild and tolerable, we have confirmed that LVL is a safe and effective procedure in children </=25 kg, and that AutoPBSC software could be reliably used in these patients, provided that an experienced team performs the procedure.

Abstract
BACKGROUND The goal of the current study was to determine the prostate-specific antigen (PSA) and objective response rates and the pharmacokinetics associated with a monthly x 3 one-hour infusion of suramin in 58 patients with hormone-refractory prostate carcinoma. METHODS A PSA response was defined as a > 50% reduction in the PSA level from baseline for at least 3 consecutive evaluations over a minimum of 6 weeks. The suramin dose was 2400 mg/m(2) taken intravenously on Day 1, 1620 mg/m(2) on Day 29, and 1292 mg/m(2) on Day 57. All patients received 0.5 mg dexamethasone twice daily. RESULTS Among 56 evaluable patients (median entry PSA level, 229.5 ng/mL), there were 21 PSA responders (37.5%). Among 27 patients with measurable disease, there were 5 responders (4 partial and 1 complete). The median overall survival time was 15.3 months. Grade III fatigue (14.1%) was the predominant toxicity observed. Suramin plasma levels remained high even 3 months after treatment was discontinued. Among the 12 evaluable patients who previously had received chemotherapy, the PSA response rate was 42%; one response was observed among 4 patients with measurable disease, and the median survival was 12 months. CONCLUSIONS Monthly bolus suramin was well tolerated, reduced PSA levels, and induced objective responses, even in patients who previously had received chemotherapy.

Abstract
In a previous phase II trial of the synthetic topoisomerase I inhibitor, 9-aminocamptothecin (9-AC), given as a 72-h infusion, we identified modest single agent activity of 9% in patients with previously untreated advanced non-small cell lung cancer (NSCLC). Preclinical studies suggested that a more prolonged continuous infusion of the drug might lead to greater antitumor activity. A phase I study recommended a phase II dose of 25 microg/m2/hr for 120 h (3000 microg/m2 over 5 days), administered for 2 consecutive weeks of a 3-week cycle. We utilized this schedule and enrolled 13 chemotherapy-naïve patients with Stage IIIB and IV NSCLC in this trial: median age 67 (range 57-74); 46% male; 92% stage IV; and median performance status 1. Twelve patients are available for response and toxicity evaluation after 2 cycles of therapy. One patient achieved a partial response. Four patients had stable disease while seven patients had progressive disease. Patients with stable or progressive disease after two cycles received no additional 9-AC, and were offered conventional chemotherapy. The median survival time was 10.2 months and the one-year survival rate 28% (95% confidence interval, 5-58%). Significant toxicities included myelosuppression, fatigue, and anorexia. One patient had grade 4 neutropenia following the first week of cycle 2, and did not receive additional therapy. There were no neutropenia-related infections. These data suggest that this prolonged schedule is unlikely to increase 9-AC's very modest activity in NSCLC above that seen with the simpler 72-h administration schedule. Further evaluation of 9-AC in NSCLC is not recommended.

Abstract
Secondary myelodysplastic syndrome (MDS) and acute leukemia (AL) are well-known complications of antineoplastic therapy. The incidence of these serious complications after autologous hematopoietic transplantation ranges from 1.1% to 24%. Prior chemotherapy is its most likely cause, but other variables related to these long-term complications are seriously discussed. There is evidence that priming of progenitor cells isolated from peripheral blood with chemotherapy is also related to a higher risk of secondary MDS/AL. Whether progenitor cells isolated from bone marrow or peripheral blood after mobilization only with cytokines are related to higher risk is a controversial issue. In this paper, we analyze the incidence and variables related to these complications in a series of 99 patients diagnosed with lymphoma or multiple myeloma who underwent autologous transplantation using hematopoietic progenitors isolated from peripheral blood mobilized with granulocyte colony-stimulating factor (G-CSF). The probability of MDS/AL in patients alive 5 years after transplant in our series is 8.58%, similar to that reported in other series using bone marrow grafts. The total dose of cyclophosphamide ( p=0.099), the number of chemotherapy cycles ( p=0.04) received before transplant, and the total dose of mononuclear cells infused at the time of transplant were the only variables associated with secondary MDS/AL. Autologous transplantation with progenitor cells isolated from peripheral blood after mobilization with cytokines has probability and risk factors for secondary MDS/AL development similar to bone marrow grafts when compared with other published series.

Abstract
Veno-occlusive disease of the liver (VOD) is an important complication in hematological transplantation. The aim of this study is to analyze the risk factors for VOD and other forms of liver toxicity in a cohort of 180 peripheral stem cell transplants performed in our Center. We find that elevated pretransplant levels of serum ferritin are the most important risk marker for VOD. We believe that ferritin reflects damage induced by oxygen radicals resulting from iron-mediated catalysis. We also discuss different risk factors for VOD and other forms of liver toxicity, suggesting diferent pathogenic mechanisms.

Abstract
BACKGROUND AND OBJECTIVES Although the use of drugs which damage stem cells is common in patients with Hodgkin's disease (HD), factors affecting peripheral blood progenitor cell (PBPC) mobilization have not been clearly established in this group of patients. The aim of this study was to identify factors associated with poor PBPC mobilization in patients with HD. DESIGN AND METHODS In order to address this issue we have evaluated in 54 patients with HD mobilized with G-CSF alone the following factors: sex, age, histologic subtype, B symptoms at diagnosis, status of remission, previous chemotherapy and radiotherapy, interval from diagnosis and last chemotherapy cycle to harvest, and dose of G-CSF. Univariate analysis was performed using Student's t-test, Pearson's correlation and Spearman's correlation. A stepwise regression model was used to determine which of the variables was the most predictive of PBPC mobilization. RESULTS In univariate analysis poorer PBPC mobilization was observed in patients who had previously received at least two courses of mini-BEAM (p=0.006), a high number of different chemotherapy regimens (p=0.002), a chemotherapy score >30 (p=0.02) and more than 9 months of alkylating agents (p=0.07). We did not find radiotherapy to be a significant factor affecting progenitor cell yield (p=0.59). In the stepwise regression model, only the previous administration of two or more mini-BEAM cycles predicted a poor PBPC yield (p=0.006). INTERPRETATION AND CONCLUSIONS Previous chemotherapy, principally exposure to a mini-BEAM regimen, seems to be the principal factor affecting collection of PBPC in patients with HD mobilized with G-CSF alone. Since mini-BEAM is an effective salvage regimen in relapsed or refractory HD, collection of PBPC should be planned when there has been no or only minimal exposure to a mini-BEAM regimen.

Abstract
BACKGROUND Data on the administration of rHuG-CSF to normal donors <18 years old are very limited. STUDY DESIGN AND METHODS The results of rHuG-CSF administration to 61 donors <18 years old (Group A) were retrospectively evaluated and compared with results from 353 donors > or = 18 years old (Group B) who are included in the Spanish National Donor Registry. The mean age (range) in Group A and B was 14 (1-17) and 38 (18-71) years, respectively (p<0.001). The mean dose of rHuG-CSF was 10 microg per kg per day (range, 9-16) during a mean of 5 days (range, 4-6). Central venous access was placed more frequently in younger donors (25% vs. 6%; p<0.001). RESULTS The mean number of CD34+ cells collected was 7.6 and 6.9 x 10(6) per kg of donor's body weight in Group A and B, respectively. Fifty-six percent of Group A donors needed only one apheresis to achieve > or = 4 x 10(6) CD34+ cells per kg versus 39 percent of Group B donors (p = 0.01). Side effects were more common in Group B (71% vs. 41%; p<0.001). CONCLUSION The administration of rHuG-CSF to donors <18 years old leads to CD34+ cell mobilization in a pattern similar to that observed in adults. Greater age was associated with a more frequent requirement for more than one apheresis to achieve a similar number of CD34+ cells.

Abstract
Although autologous PBPC transplantation is being used increasingly for the treatment of breast cancer, there are few data on factors influencing mobilization and engraftment in these patients. We have analyzed these factors in 70 patients with advanced or metastatic breast cancer undergoing autologous PBPC transplantation. All patients were mobilized after stimulation with G-CSF, and a median of 3.16 x 10(6)/kg CD34+ cells (range 0.75-23.33) were infused. All patients received conditioning with a combination of cyclophosphamide, thiotepa, and carboplatin, and postinfusion G-CSF was administered to 60 patients. The median times to reach 0.5 x 10(9)/L and 1 x 10(9)/L neutrophils were 10 and 11 days, respectively. The median times to obtain 20 x 10(9)/L and 50 x 10(9)/L platelets were 12 and 18 days, respectively. An analysis of factors that influence CD34+ cell collection was performed by linear regression. Previous radiation therapy and increasing age were associated with lower numbers of CD34+ cells collected. Those variables that could influence the tempo of engraftment were examined by multivariate analysis using Cox regression models. The number of CD34+ cells infused was found to influence both neutrophil and platelet recovery. The use of G-CSF after transplant, accelerated neutrophil recovery, and having more than six cycles of previous chemotherapy was an unfavorable factor for recovering >50 x 10(9)/L platelets.

Abstract
A Spanish National PBPC Donor Registry has recently been established for short- and long-term safety data collection in normal donors receiving rhG-CSF. To date, 466 donors have been included in the Registry. Median (range) dose and duration of rhG-CSF administration was 10 microg/kg/day (4-20) and 5 days (4-8), respectively. Donors underwent a median of two aphereses (range, 1-5). Adverse effects consisted mainly of bone pain (90.2%), headache (16.9%) and fever (6. 1%), but no donor discontinued rhG-CSF prematurely due to toxicity. Side-effects were more frequent in donors receiving >10 microg/kg/day than in those with lower doses (82.8% vs 61.8%; P = 0. 004). A significant decrease between baseline and post-apheresis platelet counts was the most important analytical finding (229 x 10(9)/l vs 140 x 10(9)/l; P < 0.0001), with a progressive reduction in platelet count with each apheresis procedure. One donor developed pneumothorax that required hospitalization due to central venous line placement. The mean CD34+ cell dose collected was 6.9 x 10(6)/kg (range, 1.3-36), with only 14 donors (2.9%) not achieving a minimum target of CD34+ cells of 2 x 10(6)/kg. No definitive information about potential long-term side effects is yet available. However, we hope this National Registry will serve as a useful basis for better monitoring of the efficiency and side-effects of cytokine administration in healthy people.

Abstract
In order to assess the potential clinical benefit of filgrastim (G-CSF) after peripheral blood stem cell (PBSC) autotransplantation a randomized study was begun in our center in July 1997: 62 patients were involved (30 received filgrastim after PBSC infusion and 32, the control group, received no cytokines). All were adults (median 40 years, range 18-65). Patients with one of three different pathologies were recruited: 28 had advanced breast carcinoma, 23 had lymphomas (12 Hodgkin's disease and 11 non-Hodgkin's lymphoma) and 11 had de novo AML. All of them were transplanted using myeloablative chemotherapy conditioning regimens. G-CSF was administered subcutaneously from day +5 in the treated group at a dose of 5 microg/kg body weight/day. The numbers of CD34+ and mononuclear (MNC) cells infused were similar in each group. Only minor differences regarding the use of G-CSF could be inferred from the analysis of the data. Faster granulocyte engraftment was evident in the treated group (mean of 10 vs 12 days to achieve >0.5 x 109/l granulocytes, P = 0.0008), without differences in incidence and severity of infections, days of fever or duration of antibiotic treatment between groups. There was slightly slower platelet engraftment (mean of 15 days in the group with G-CSF vs 12 days in the other group to achieve >20 x 109/l platelets, P = NS) in this series, but there were no differences in incidence and severity of haemorrhage or platelet transfusion support. Considering the economical costs, the median expenditure per inpatient stay was Eur5961 (range Eur4386-Eur17186) in the G-CSF group compared with Eur5751 (range Eur3676-Eur15640) in the control group (P = 0.47). From our data it could be concluded that for adult patients transplanted with PBSC there is no clear beneficial impact of post-infusion G-CSF administration.

Abstract
A simplified cryopreservation method for bone marrow (BM) and peripheral blood progenitor cells (PBPC) was utilized in hematopoietic cell transplantation of 213 patients with hematological or solid neoplasms after ablative chemotherapy (187 with peripheral blood progenitor cells and 26 with bone marrow). Cells were cryopreserved, after addition of autologous fresh plasma with DMSO, without HES, by freezing to -80 degrees C in a methanol bath and non-programmed freezer. For the patients autotransplanted with PBPC, the median period necessary for recovery of more than 0.5 x 10(9)/l granulocytes was 11 days (range 6-44), and 15 (8-204) days were required to obtain more than 20 x 10(9)/l platelets. For the patients autotransplanted with BM, the median period necessary to recover >0.5 x 10(9)/l granulocytes was 12 days (range 9-33), and 24 (12-57) days to obtain more than 20 x 10(9)/l platelets. These results support this method as being very effective in achieving high-quality cryopreservation. The procedure, which uses a non-programmed freezer, simplifies and reduces enormously the cost of the technical measures currently in use, enabling its adoption in almost any clinical oncological institution.

Abstract
Severe combined immunodeficiencies are a group of rare genetic disorders characterized by a profound impairment in both cellular and humoral immune functions. This disorder is rapidly fatal without bone marrow transplantation. Unfortunately, most children lack a histocompatible donor. The development of T cell depletion allows for haploidentical transplantation with reduced risk of GVHD. In the present article, we discuss the case of a child diagnosed with X-linked severe combined immunodeficiency for whom haploidentical peripheral blood stem cell transplantation was performed by selecting CD34-positive cells followed by depletion of T cells. Both selection and purging were performed using immunoselection by the biotin-avidin system (CEPRATE System). The CD34-enriched T cell-depleted product contained 5.05 x 10(6)/kg CD34+ cells with only 0.01 [corrected] x 10(6)/kg CD3+ cells, achieving a T cell depletion of 4.2 log.

Abstract
This case report describes a patient with recurrent and refractory acute lymphoblastic leukaemia (ALL-L3), who relapsed four months after a HLA identical allogeneic Peripheral Blood Stem Cell (PBSC) transplantation; he was treated after relapse with intensive chemotherapy and then he received leukocyte infusion from her sibling donor. A long term Complete Remission (CR) was achieved, with complete chimerism and without signs of chronic GVHD. Thirteen months after Donor Leukocyte Infusion (DLI), he developed a relapse (4% blasts in BM), and a second infusion of leukocytes with the same chemotherapy schedule was performed. Six months after the second DLI the patient is alive. Since responses to Donor Lymphocyte Infusions (DLI) are uncommon in ALL, the possible causative factors for this unusual response are discussed.

Abstract
A simplified method to remove and cryopreserve peripheral blood stem cells (PBSC) was utilised to restore the bone marrow in 31 patients with haematological or solid neoplasms after ablative chemotherapy. Mobilization was performed with subcutaneous G-CSF, starting 4 days before the first PBSC harvest and continuing to the last day of harvest. Cryopreservation was carried out by freezing cells to -80 degrees C after addition of autologous fresh plasma with DMSO, in a methanol bath and non-programmed freezer. The PBSC were reinfused in all cases. The mean quantity of CD34 cell (x 10(6)/kg) infused was 6.5 +/- 6.7. The mean number of procedures needed to harvest an appropriate number of PBSC was 3.6 +/- 1.3. The mean times necessary to recover more than 0.5 x 10(9)/l granulocytes were 11 +/- 4 (8-30) days and 23 +/- 13 (8-55) days to obtain more than 20 x 10(9)/l platelets. These results confirm our method as very effective in achieving a high-quality harvest, and it was used in paediatric and adult patients without problems. This procedure, using a non-programmed freezer, simplifies and reduces enormously the cost of the technical measures currently used, enabling their adoption in almost any clinical oncological institution.

Abstract
The relationship between two key factors involved in infant care and the frequency and duration of diarrhea, was search for in a cohort of rural infants followed-up from birth onwards. The specific questions asked were if the profile of mother-infant interaction, and the total score on home stimulation available to the infant were associated with the presence or absence of diarrhea, and with its total duration, expressed as the percentage of days with diarrhea over the number of days of age, in each semester of the first year of life of the infants. Frequency an duration of diarrhea, mother-infant interaction, and scores on home stimulation available to the infant showed no difference between baby-boys and baby-girls. The behavior of mothers of infants with diarrhea was not significantly different than the behavior exhibited by mothers of infants without diarrhea; even in the scales related to "quantity of physical contact with the infant", "type of physical contact with the infant", "response to infant's needs", and "sensitivity toward the infant". Similarly, neither the quality nor quantity of home stimulation showed association with the presence of diarrhea. Finally, none of the two microenvironmental attributes influenced the duration of diarrhea in either semester of the life of the infant. Although diarrhea is one of the most frequent antecedents of severe clinical malnutrition and in the latter both mother-infant interaction and home stimulation play a prominent role in the evolution from second degree to third clinical degree malnutrition, it seems important than those factors have a minimal influence in relation to diarrhea during the first year of life.
