Graft-versus-lymphoma effect in a 64-year-old caucasian woman after allogeneic stem-cell transplantation: a case report

<p>Abstract</p> <p>Introduction</p> <p>The existence of a graft-versus-lymphoma effect is well established. When lacking a firm diagnosis, however, the clinician is challenged to to weigh the potential benefits of the graft-versus-lymphoma effect against potential dangers of graft-versus-host disease as well as against generalized (viral) infections.</p> <p>Case presentation</p> <p>We present evidence for a graft-versus-lymphoma effect in a 64-year-old caucasian woman with a transplanted peripheral blood-stem-cell graft from her Human Leukocyte Antigen-identical sister, and propose diagnostic measures to distinguish between graft-versus-host effect, and against viral disease or drug-induced reactions.</p> <p>Conclusion</p> <p>We were able to identify an allogeneic graft-reaction against progressive lymphoma alongside an erythema consistent with acute graft-versus-host disease of the skin. Establishing a firm diagnosis enabled us to decide against T-cell suppression (such as by using cyclosporine). Anti-lymphoma activity was favoured, by means of the allogeneic graft, local radiation and immunotherapy. This illustrates the importance of a sound differential diagnosis of erythema after allogeneic stem-cell transplantation, including assessment of viral disease of the affected tissue.</p

Successful treatment of severe sinusoidal obstruction syndrome despite multiple organ failure with defibrotide after allogeneic stem cell transplantation: a case report

<p>Abstract</p> <p>Introduction</p> <p>We report a case of sinusoidal obstruction syndrome, a typical and life-threatening complication after allogeneic stem-cell transplantation, successfully treated with defibrotide despite massive multiple organ failure.</p> <p>Case presentation</p> <p>A 64-year-old Caucasian woman underwent allogeneic peripheral blood stem-cell transplantation from her human leukocyte antigen-identical sister against aggressive lymphoplasmocytoid immunocytoma. Seven days later, the patient developed severe sinusoidal obstruction syndrome according to the modified Seattle criteria. We initiated treatment with defibrotide. Despite early treatment, multiple organ failure with kidney failure requiring dialysis and ventilator-dependent lung failure aggravated the clinical course. Furthermore, central nervous dysfunction occurred as well as transfusion refractory thrombocytopenia.</p> <p>Conclusion</p> <p>As highlighted in our report, defibrotide is the most promising drug in the treatment of the formerly, almost lethal, severe sinusoidal obstruction syndrome to date. This is demonstrated very clearly in our patient. She improved completely, even after renal, cerebral and respiratory failure.</p

Nine months to progression using fourth-line liposomally encapsulated paclitaxel against hepatocellular carcinoma

Background: Hepatocellular carcinoma (HCC) is the third most common cause of cancer deaths. Difficulties to diagnose HCC at early stages remain the major obstacle to curative (surgical) therapy. Therapy in advanced stages has to be considered palliative. In this situation, a considerable amount of attention should be paid to innovative treatment strategies, e. g. including antiangiogenetic drugs. Results: We report on the successful treatment of a patient suffering from progressive HCC with a novel drug (EndoTAG (R)-1, formerly named LipoPac (R)) currently investigated in phase II studies. This drug consists of liposomally encapsulated paclitaxel. Its liposomal formulation favors the drug's adherence to the tumor neovasculature, in effect starving the tumor. Conclusions: EndoTAG (R)-1 stopped tumor progression for 9 months in our patient. This, along with successes observed testing this drug against other indications, makes it a suitable candidate for future clinical trials. Copyright (C) 2008 S. Karger AG, Basel

Major central nervous system complications after allogeneic stem cell transplantation: A large retrospective study on 888 consecutive adult patients.

AbstractObjectivesMajor complications affecting the central nervous system (CNS) present a challenge after allogeneic stem cell transplantation (allo‐SCT).MethodsIncidence, risk factors, and outcome were retrospectively analyzed in 888 patients in a monocentric study.ResultsCumulative incidence (CI) of major CNS complications at 1 year was 14.8% (95%CI 12.3%‐17.2%). Median follow‐up is 11 months. CNS complications were documented in 132 patients: in 36 cases, classified metabolic; 26, drug‐related neurotoxicity (14 attributed to cyclosporine A, 4 to antilymphocyte globulin); 11, cerebrovascular (ischemic n = 8, bleeding n = 3); 9, infections; 9, psychiatric; and 9, malignant. The cause of CNS symptoms remained unclear for 37 patients (28%). Multivariate analysis demonstrated an association of CNS complication with patient age (P < .001). The estimated OS of patients with any CNS complication was significantly lower than in patients without neurological complications (P < .001), and the CI of non‐relapse mortality (NRM) was higher for patients with CNS complication (P < .001). A significant negative impact on survival can only be demonstrated for metabolic CNS complications and CNS infections (NRM, P < .0001 and P = .0003, respectively), and relapse (P < .0001).ConclusionCNS complications after allo‐SCT are frequent events with a major contribution to morbidity and mortality. In particular, the situations of unclear neurological complications need to be clarified by intensive research

Scabies crustosa in a recipient of an allogeneic stem cell transplantation

Introduction!#!The current treatment concepts of fracture-related infection (FRI) [Consensus Conference (Anti-Infection Task Force (AITF)) on the definition of acute or chronic osteomyelitis (cOM)] are associated with unsolved challenges and problems, underlining the need for ongoing medical research.!##!Method!#!Literature review of treatments for FRI and description of own cases.!##!Results!#!We could include eight papers with 394 patients reporting treatments and outcome in FRI. The infection was resolved in 92.9% (mean) of all treatments. The mean follow-up was 25 months with a persistent non-union in 7% of the patients. We diagnosed 35 (19f/16m; 56.4 ± 18.6 years) patients with bone infections anatomically allocated to the proximal and distal femur (12×), the pelvis (2×), distal tibia (3×), tibial diaphysis (11×), the ankle joint (4×) and calcaneus (3×). These 35 patients were treated (1) with surgical debridement; (2) with antibiotic-eluting ceramic bone substitutes; (3) bone stabilization (including nail fixation, arthrodesis nails, plates, or external ring fixation), (4) optionally negative pressure wound therapy (NPWT) and (5) optionally soft tissue closure with local or free flaps. The mean follow-up time was 14.9 ± 10.6 months (min/max: 2/40 month). The overall recurrence rate is low (8.5%, 3/35). Prolonged wound secretion was observed in six cases (17.1%, 6/35). The overall number of surgeries was a median of 2.5.!##!Conclusion!#!The results in the literature and in our case series are explicitly promising regarding the treatment of posttraumatic fracture-related infection
