BACKGROUND/AIMS: Rituximab-cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) every 14 days seems to achieve better outcomes than R-CHOP every 21 days in diffuse large B-cell lymphoma (DLBCL) patients. Currently, the standard regimen is R-CHOP every 21 days. METHODS: This is a phase II clinical trial of treatment with 6 cycles of R-CHOP-14 with pegfilgrastim support in 2 populations of previously untreated DLBCL patients aged ≥65 years (n = 73) or <65 years (n = 51) with low-risk International Prognostic Index scores (0-2)...

BACKGROUND: No standard first-line systemic treatment for mucosa-associated lymphoid tissue (MALT) lymphoma is available. In a phase 2 study we aimed to assess the safety and activity of a response-adapted combination of bendamustine plus rituximab as upfront treatment for this type of lymphoma. METHODS: In a multicentre, single-arm, non-randomised, phase 2 trial, we enrolled patients with MALT lymphoma at any site and stage and treated them with bendamustine (90 mg/m(2) on days 1 and 2) plus rituximab (375 mg/m(2) on day 1), every 4 weeks...

BACKGROUND: Umbilical cord blood transplantation (CBT) is an established alternative source of stem cells in the setting of unrelated transplantation. When compared with other sources, single-unit CBT (sCBT) is associated with a delayed hematologic recovery, which may lead to a higher infection-related mortality (IRM). Co-infusion with the sCBT of CD34+ peripheral blood stem cells from a third-party donor (TPD) (sCBT + TPDCD34+) has been shown to markedly accelerate leukocyte recovery, potentially reducing the IRM...

BACKGROUND: Plasmablastic lymphoma (PBL) is a rare entity which is often causally related to infection by the Human Immunodeficiency Virus (HIV). Despite its predilection for oral cavity involvement, multiple cases of extra-oral involvement have been reported in the literature, more often among immunocompetent individuals. CASE REPORT: Herein we present the first case of primary PBL of the breast in an otherwise immunocompetent 36-year-old woman who was successfully treated with consolidation megatherapy and autologous stem cell transplantation...

Polyomaviruses BK and JC are ubiquitous viruses with high seroprevalence rates in general population. Following primary infection, polyomaviruses BK and JC persist latently in different sites, particularly in the reno-urinary tract. Reactivation from latency may occur in normal subjects with asymptomatic viruria, while it can be associated to nephropathy (PVAN) in kidney transplantat recipients. PVAN may occur in 1%-10% of renal transplant patients with loss of the transplanted organ in 30% up to 80% of the cases...

Human herpesvirus 6B (HHV-6B) is causative agent for exanthem subitum, which is common febrile illness in infant. This disease is generally benign and self-limited disease, however rarely causes several central nervous system complications. As various types of HHV-6B encephalitis has been demonstrated, pathophysiology of the disease would be complicate. Thus, different therapeutic strategies should be established for each type of HHV-6B encephalitis at the time of primary viral infection. Meanwhile, this virus can reactivate in transplant recipients and cause post-trasplant limbic encephalitis...

Solid-organ transplant recipients are at increased risk of developing cancer compared with the general population. Tumours can arise de novo, as a recurrence of a preexisting malignancy, or from the donated organ. The ATOS (Aula sobre Trasplantes de Órganos Sólidos; the Solid-Organ Transplantation Working Group) group, integrated by Spanish transplant experts, meets annually to discuss current advances in the field. In 2011, the 11th edition covered a range of new topics on cancer and transplantation. In this review we have highlighted the new concepts and best practices for managing cancer in the pre-transplant and post-transplant settings that were presented at the ATOS meeting...

We attempt to describe the epidemiology and outcome associated with cefotaxime-resistant (CTX-R) Klebsiella spp bacteraemia. Klebsiella spp bloodstream infection episodes prospectively collected through a blood culture surveillance programme from January 1991 to December 2008 in a single institution were analysed. A total of 910 monomicrobial episodes of Klebsiella spp bacteraemia were identified during the study period. The most important sources were from urinary tract infection, unknown sources, billiary focus and catheter related infection...

Fever in an immunocompromised patient like the transplanted subject is usually due to an overt or occult infection. Clinicians must make important decisions to find the cause of fever, and also concerning the timing and adequacy of empiric antibiotic therapy. However, occasionally, fever is not due to an infectious cause. A correct identification of its causes may avoid a needlessly prolonged course of antibiotics. Herein we have reported a kidney transplant patient with a febrile syndrome, which appeared after endovascular aortoiliac stent-graft placement, that was finally attributed to a noninfectious cause like postimplantation syndrome...

We conducted a phase II trial to investigate the safety and efficacy of alemtuzumab in treating steroid-refractory acute graft-versus-host disease (aGVHD) grade II or higher after stem cell transplantation. Ten adult patients (6 with aGVHD grade III and 4 with aGVHD grade IV) were included in the study. Nine patients had gastrointestinal tract involvement, 7 had skin involvement, and 5 had liver involvement. Five patients responded to treatment, 2 with complete response and 3 with partial response. Eight infectious events (4 of grade 3-4) and 7 cytomegalovirus (CMV) reactivations were observed...

We reviewed the records of the renal transplant patients followed at our hospital to determine short-term outcome and complications. Sixty-five renal transplant patients, follow-up for two years were included in this study. Of these patients 40 (61.5%) were males, 33 (50.7%) were Saudis with mean age of 37.2 +/- 11.7 years. Donors were living related (LRD) in 23 (35%), living non-related (LNRD) in 27 (42%) and cadaveric (CAD) in 15 (23%). Thirty-two transplants were carried out at Medinah, 21 in India and the rest in other centers inside Saudi Arabia...

Invasive fungal infections (IFI) are the third cause of infectious complications in recipients of solid organ transplants (SOT), showing an incidence of 5-42% depending of the trasplanted organ. Moreover, IFI account for significant morbility and mortality in SOT, ranging between 25-95% depending on the type of fungus and its organ localization. Different strategies (prophylaxis, preemptive treatment, treatment, antifungal combinations, routes of administration) have been tested to improve the prognosis of IFI in SOT...

We evaluated the occurrence of severe infections in 192 consecutive adult recipients of volunteer unrelated donor allogeneic hematopoietic stem cell transplants, with a detailed analysis of severe infections after receipt of cord blood transplants (CBTs; n = 48) or bone marrow transplants (BMTs)/peripheral blood stem cell transplants (PBSCTs; n = 144). At a 3-year median follow-up, CBT recipients had a higher risk of developing any severe infection (85% versus 69% in BMT/PBSCT recipients, P < .01). CBT recipients had a higher incidence of severe bacterial infections before day +100, but at 3 years the risks of these and other infections were similar in the CBT and BMT/PBSCT groups...

This paper describes the general situation regarding heart transplantation in Spain and the results obtained using the technique, incorporating data for the year 2004. In 2004, 294 heart transplants were carried out, which brings the total number of procedures performed since 1984 to 4680. Clinically, the typical heart transplant recipient in Spain is male, aged around 50 years, has blood group A, has non-revascularizable coronary artery disease, and is in NYHA functional class IV/IV. The percentage of emergency heart transplantations was 35%, which is higher than in the previous year (29%), and higher than the mean for the preceding 5 years (22%)...
