Antiviral prophylaxis in patients with solid tumours and haematological malignancies--update of the Guidelines of the Infectious Diseases Working Party (AGIHO) of the German Society for Hematology and Medical Oncology (DGHO).

Reactivation of viral infections is common in patients with solid tumour or haematological malignancy. Incidence and severity depend on the extent of cellular immunosuppression. Antiviral prophylaxis may be effective to prevent viral reactivation. In 2006, the Infectious Diseases Working Party of German Society for Hematology and Medical Oncology (DGHO) published guidelines for antiviral prophylaxis in these patient populations. Here, we present an update of these guidelines for patients with solid and haematological malignancies undergoing antineoplastic treatment but not allogeneic stem cell transplantation. Relevant literature for reactivation of different viruses (herpes simplex virus (HSV), varicella zoster virus (VZV), hepatitis B virus (HBV) and respiratory viruses) is discussed to provide evidence-based recommendations for clinicians taking care of this patient population. We recommend a risk-adapted approach with (val)acyclovir against HSV and VZV in patients treated with alemtuzumab, bortezomib or purine analogues. Seasonal vaccination against influenza is recommended for all patients with solid or haematological malignancies regardless of antineoplastic therapy. Hepatitis B screening is recommended in lymphoproliferative disorders, acute leukaemia, and breast cancer, and during treatment with monoclonal anti-B-cell antibodies, anthracyclines, steroids and in autologous stem cell transplantation. In those with a history of hepatitis B prophylactic lamivudine, entecavir or nucleotide analogues as adefovir are recommended to prevent reactivation.

Depletion of autoreactive immunologic memory followed by autologous hematopoietic stem cell transplantation in patients with refractory SLE induces long-term remission through de novo generation of a juvenile and tolerant immune system.

Clinical trials have indicated that immunoablation followed by autologous hematopoietic stem cell transplantation (ASCT) has the potential to induce clinical remission in patients with refractory systemic lupus erythematosus (SLE), but the mechanisms have remained unclear. We now report the results of a single-center prospective study of long-term immune reconstitution after ASCT in 7 patients with SLE. The clinical remissions observed in these patients are accompanied by the depletion of autoreactive immunologic memory, reflected by the disappearance of pathogenic anti-double-stranded DNA (dsDNA) antibodies and protective antibodies in serum and a fundamental resetting of the adaptive immune system. The latter comprises recurrence of CD31(+)CD45RA(+)CD4(+) T cells (recent thymic emigrants) with a doubling in absolute numbers compared with age-matched healthy controls at the 3-year follow-up (P = .016), the regeneration of thymic-derived FoxP3(+) regulatory T cells, and normalization of peripheral T-cell receptor (TCR) repertoire usage. Likewise, responders exhibited normalization of the previously disturbed B-cell homeostasis with numeric recovery of the naive B-cell compartment within 1 year after ASCT. These data are the first to demonstrate that both depletion of the autoreactive immunologic memory and a profound resetting of the adaptive immune system are required to reestablish self-tolerance in SLE.

A modified EBMT risk score predicts the outcome of patients with acute myeloid leukemia receiving allogeneic stem cell transplants.

The systematic and standardized pretransplant risk assessment represents an important tool to predict the outcome of patients undergoing allogeneic stem cell transplantation (alloSCT). To investigate the capacity of a modified European group for blood and marrow transplantation (mEBMT) risk score to predict the outcome of patients with acute myeloid leukemia (AML) receiving allogeneic stem cell transplants, we retrospectively analyzed 214 patients transplanted at our center between 1995 and 2008. Overall survival (OS) of the whole cohort at 1, 3, and 5 yr was 62%, 48%, and 45%, whereas the cumulative incidence of relapse or non-relapse mortality (NRM) was 26%, 33%, and 33% or 19%, 21%, and 22%. In univariate analysis, a higher mEBMT risk score was associated with an inferior OS ranging from 69% for patients with a score of 0/1 to 26% for patients with a score of 5/6 at 5 yr (P < 0.0001) and steadily increasing hazard ratios for each additional score point. Likewise, a higher mEBMT risk score was associated with an increased incidence of relapse (P = 0.049). Importantly, the prognostic value of the mEBMT risk score in terms of OS and relapse was maintained in multivariate analysis. Taken together, this indicates that a mEBMT risk score may be used to predict the outcome of patients with AML following alloSCT.

A reappraisal of Gaucher disease-diagnosis and disease management algorithms.

Type 1 (non-neuronopathic) Gaucher disease was the first lysosomal storage disorder for which an effective enzyme replacement therapy was developed and it has become a prototype for treatments for related orphan diseases. There are currently four treatment options available to patients with Gaucher disease, nevertheless, almost 25% of Type 1 Gaucher patients do not gain timely access to therapy because of delays in diagnosis after the onset of symptoms. Diagnosis of Gaucher disease by enzyme testing is unequivocal, but the rarity of the disease and nonspecific and heterogeneous nature of Gaucher disease symptoms may impede consideration of this disease in the differential diagnosis. To help promote timely diagnosis and optimal management of the protean presentations of Gaucher disease, a consensus meeting was convened to develop algorithms for diagnosis and disease management for Gaucher disease.

A modified EBMT risk score and the hematopoietic cell transplantation-specific comorbidity index for pre-transplant risk assessment in adult acute lymphoblastic leukemia.

BACKGROUND: Disease stage is the most important prognostic parameter in allogeneic hematopoietic cell transplantation (HCT) for acute lymphoblastic leukemia, but other factors such as donor/host histocompatibility and gender combination, recipient age, performance status and comorbidities need to be considered. Several scoring systems are available to predict outcome in HCT recipients; however, their prognostic relevance in acute lymphoblastic leukemia is not well defined. DESIGN AND METHODS: In the present study we evaluated a modified EBMT risk score (mEBMT) and the HCT-specific comorbidity index (HCT-CI) in 151 adult acute lymphoblastic leukemia patients who received allogeneic HCT from 1995 until 2007 at our center. RESULTS: Disease status was first complete remission (CR1) (47%), CR>1 (21%) or no CR (32%). Overall survival (OS) at one, two and five years was 62%, 51% and 40% and non-relapse mortality (NRM) was 21%, 24% and 32%. Median mEBMT was 3 (0-6). Higher mEBMT was associated with inferior OS (hazard ratio per score unit (HR): 1.50, P<0.001), higher NRM (HR: 1.36, P=0.042) and higher relapse mortality (HR: 1.68, P<0.001). Disease stage was the predominant prognostic factor in this score. Comorbidities were present in 71% of patients with mild hepatic disease (29%), moderate pulmonary disease (28%) and infections (23%) being the most common. Median HCT-CI was 1 (0-9). In univariate analysis a trend for inferior OS (HR: 1.08, P=0.20) and higher NRM (HR: 1.14, P=0.11) with increasing HCT-CI was observed but the level of significance was not reached. In additional analyses we found that reduced Karnofsky Performance Status (KPS) was associated with inferior OS (HR: 1.34, P=0.023) and higher relapse mortality (HR: 1.71, P=0.001) when analyzed univariately. However, KPS was associated with disease stage and significance was lost in multivariate analysis. CONCLUSIONS: The mEBMT was prognostic in our patient cohort with predominant influence of disease stage, whereas a trend but no significant prognostic value was observed for the HCT-CI.

Direct assessment of thymic reactivation after autologous stem cell transplantation.

Methods to quantify Th cell reconstitution after immunosuppressive therapies such as hematopoietic stem cell transplantation are becoming a key issue since persistent Th cell deficiencies may result in severe complications and adverse events. We employed here cytometric monitoring of CD31+ thymus-naive Th cells for the direct assessment of human thymic function in 10 patients undergoing autologous stem cell transplantation for severe autoimmune diseases. High frequencies of posttransplant recurring naive Th cells coexpressed CD31 and stable long-term reconstitution with elevated absolute counts of CD31+ thymus-naive Th cells that were enriched with T cell receptor excision circles was demonstrated. Cytometric monitoring of CD31+ thymus-naive Th cells enables to directly evaluate human thymic function ex vivo.

Sequential high-dose cytarabine and mitoxantrone (S-HAM) versus standard double induction in acute myeloid leukemia-a phase 3 study.

Dose-dense induction with the S-HAM regimen was compared to standard double induction therapy in adult patients with newly diagnosed acute myeloid leukemia. Patients were centrally randomized (1:1) between S-HAM (2nd chemotherapy cycle starting on day 8 = "dose-dense") and double induction with TAD-HAM or HAM(-HAM) (2nd cycle starting on day 21 = "standard"). 387 evaluable patients were randomly assigned to S-HAM (N = 203) and to standard double induction (N = 184). The primary endpoint overall response rate (ORR) consisting of complete remission (CR) and incomplete remission (CRi) was not significantly different (P = 0.202) between S-HAM (77%) and double induction (72%). The median overall survival was 35 months after S-HAM and 25 months after double induction (P = 0.323). Duration of critical leukopenia was significantly reduced after S-HAM (median 29 days) versus double induction (median 44 days)-P < 0.001. This translated into a significantly shortened duration of hospitalization after S-HAM (median 37 days) as compared to standard induction (median 49 days)-P < 0.001. In conclusion, dose-dense induction therapy with the S-HAM regimen shows favorable trends but no significant differences in ORR and OS compared to standard double induction. S-HAM significantly shortens critical leukopenia and the duration of hospitalization by 2 weeks.

Concurrent increase of cholesterol, sphingomyelin and glucosylceramide in the spleen from non-neurologic Niemann-Pick type C patients but also patients possibly affected with other lipid trafficking disorders.

Niemann-Pick type C disease (NPC) is a neurovisceral (or, extremely rarely, only visceral) lipidosis caused by mutations in the NPC1 gene or, in a few patients, the HE1 gene, which encode sterol regulating proteins. NPC is characterised by a complex lipid anomaly including a disturbed cellular trafficking of cholesterol but also multi-lipid storage in visceral organs and brain. Lipids were studied using conventional methods in enlarged spleens that had been removed from five patients for different therapeutic and diagnostic reasons and found to have microscopic signs of lysosomal storage disease not suspected clinically. The spleen lipid findings with a concurrent accumulation of cholesterol, sphingomyelin and glucosylceramide (Acc-CSG) allowed us to suggest NPC diagnoses for these patients, who were free of neurologic symptoms. From two patients no material for confirmatory studies was available, but in two other patients NPC diagnoses could be confirmed with the filipin cytochemical cholesterol assay and NPC1 gene analysis, respectively. However, these tests and also HE1 gene analysis were negative in a third patient. Since the Acc-CSG lipid pattern seems to indicate a multi-lipid trafficking defect rather than being highly specific for NPC, this patient, if not affected with very atypical NPC, may be a candidate for a different lipid trafficking disorder. The Acc-CSG pattern was considered to be similar to the lipid pattern known for the lipid rafts, these functional cell structures being probably disorganised and accumulated in late endosomes and lysosomes of NPC cells.

Nonmyeloablative stem cell transplantation in patients with ALL and AML results in low nonrelapse mortality despite high rate of infections and GVHD.

28 patients with high-risk acute lymphoblastic (ALL) or acute myelogenous leukemia (AML) underwent nonmyeloablative stem cell transplantation (NST) from HLA-identical donors because of one or several contraindications against myeloablative conditioning. Out of 28 patients, nine (32%) had pulmonary or hepatosplenic infiltrates due to invasive fungal infections (IFI) before NST. Out of a total of 28 patients, 17 (61%) had uncontrolled leukemia before NST. Conditioning was performed with fludarabine 180 mg/m(2), busulfan 8 mg/kg and antithymocyte globulin 40 mg/kg. After NST, fever of unknown origin, sepsis or pneumonia developed in 18/28 patients (64%) overall. IFI reactivated in 3/9 patients after NST. Out of, 28 patients, 13 (46%) had late onset of acute graft-versus-host disease (GvHD), which developed at a median of 83 days after NST. GvHD frequently developed after donor lymphocyte infusions. After a median follow-up of 8 months (2-46 months), 14/28 patients (50%) have died from relapse and 1/28 patients (4%) has died from sepsis. Among 28 patients, 13 (46%) are alive in complete remission (CR). Six of 17 patients (35%) with uncontrolled disease and 7/11 patients (63%) with CR before NST are alive in CR. Probability of overall survival at 2 years is 38%. In summary, NST offers a therapeutic alternative to patients with high-risk ALL or AML, who have contraindications against conventional high-dose conditioning. Low NRM was encountered despite high morbidity, but relapse rate was high. Therefore, controlled studies are necessary to elucidate the place of NST in the therapy of high-risk acute leukemias.

Cirrhotic cardiomyopathy: a cardiologist's perspective.

Cardiac dysfunction is frequently observed in patients with cirrhosis, and has long been linked to the direct toxic effect of alcohol. Cirrhotic cardiomyopathy (CCM) has recently been identified as an entity regardless of the cirrhosis etiology. Increased cardiac output due to hyperdynamic circulation is a pathophysiological hallmark of the disease. The underlying mechanisms involved in pathogenesis of CCM are complex and involve various neurohumoral and cellular pathways, including the impaired ß-receptor and calcium signaling, altered cardiomyocyte membrane physiology, elevated sympathetic nervous tone and increased activity of vasodilatory pathways predominantly through the actions of nitric oxide, carbon monoxide and endocannabinoids. The main clinical features of CCM include attenuated systolic contractility in response to physiologic or pharmacologic strain, diastolic dysfunction, electrical conductance abnormalities and chronotropic incompetence. Particularly the diastolic dysfunction with impaired ventricular relaxation and ventricular filling is a prominent feature of CCM. The underlying mechanism of diastolic dysfunction in cirrhosis is likely due to the increased myocardial wall stiffness caused by myocardial hypertrophy, fibrosis and subendothelial edema, subsequently resulting in high filling pressures of the left ventricle and atrium. Currently, no specific treatment exists for CCM. The liver transplantation is the only established effective therapy for patients with end-stage liver disease and associated cardiac failure. Liver transplantation has been shown to reverse systolic and diastolic dysfunction and the prolonged QT interval after transplantation. Here, we review the pathophysiological basis and clinical features of cirrhotic cardiomyopathy, and discuss currently available limited therapeutic options.

Reduced intensity conditioning prior to allogeneic stem cell transplantation in first complete remission is effective in patients with acute myeloid leukemia and an intermediate-risk karyotype.

To evaluate the efficacy of reduced intensity conditioning (RIC) prior to allogeneic stem cell transplantation (alloSCT) in patients with acute myeloid leukemia (AML) in first complete remission (CR1), we retrospectively analyzed the outcome of 93 consecutive patients transplanted at our institution either following RIC (n = 37) or standard myeloablative conditioning (MAC) (n = 56) between 1999 and 2007. Projected overall survival (OS) or disease-free survival (DFS) for all patients at 1, 2, and 5 years was 78 or 70%, 65 or 57%, and 61 or 53% in the RIC group versus 73 or 70%, 68 or 62%, and 56 or 54% in the standard MAC group. In the subgroup of patients with an intermediate-risk karyotype projected OS at 1, 2, and 5 years was 86, 68, and 68% following RIC (n = 21) or 75, 69, and 66% following standard MAC (n = 36). Relapse or treatment-related mortality (TRM) was 15 or 17% (RIC group) and 26 or 14% (standard MAC group). Taken together, these data suggest that RIC-alloSCT may induce stable remissions in patients with AML transplanted in CR1. In particular, patients with an intermediate-risk karyotype ineligible to transplantation following standard MAC may benefit from RIC-alloSCT in CR1 at a low TRM.

Bisphosphonate-induced osteonecrosis of the jaws: prospective study of 80 patients with multiple myeloma and other malignancies.

A prospective study was performed in 80 patients receiving bisphosphonates in order to determine frequency of occurrence, risk factors, clinical presentation, radiology, pathology and proper treatment of osteonecrosis of the jaw (ONJ). Of 80 patients, 22 (28%) developed ONJ. There were 11 male and 11 female patients. Median age was 65 years. Ten patients (46%) had multiple myeloma (MM), 5 (23%) had breast cancer and 7 (32%) had other malignancies. Of 22 patients with ONJ, 14 patients (64%) received zoledronate, 3 (14%) received pamidronate, 4 (18%) received pamidronate later followed by zoledronate and 1 patient received ibandronate later followed by zoledronate. The median time of exposure in ONJ group was 32 months compared with 27 months in patients without ONJ. The mean induction time until bone exposure was 26 months for patients who received zoledronate, 54 months for pamidronate and 48 months for pamidronate followed by zoledronate. Thirteen patients (59%) had ONJ with bone exposure of mandible, 6 (27%) of maxilla and 3 (14%) of both jaws. ONJ occurred spontaneously in 5 patients (23%) and in 17 patients (77%) occurred after tooth extractions and surgical tooth removals (P<0.001). Nine patients (41%) had previous extractions of molars, 6 (27%) of premolars and 2 (9%) of front teeth. The cumulative hazard is significantly higher in zoledronate group (P=0.015). It was 3.48 times higher than the other group (pamidronate alone; pamidronate followed by zoledronate; ibandronate alone; etidronate alone; ibandronate followed by pamidronate; ibandronate followed by zoledronate; ibandronate followed by pamidronate and zoledronate). There was no association of ONJ with age, sex, use of high-dose or conventional chemotherapy or the use of corticosteroids, thalidomide or bortezomib (P>0.05). Patients diagnosed with multiple myeloma and breast cancer were found significantly associated with ONJ (P=0.001 and P=0.014, respectively). Long-term use of bisphosphonates (>2.5 years) increases the risk for development of ONJ. Intravenous application of zoledronate and previous dental extractions or surgical tooth removals are important risk factors of ONJ. Neither treatment with high-dose chemotherapy with autologous stem cell transplantation nor treatment with corticosteroids, thalidomide or bortezomib is a risk factor in this study.

Evaluation of whole-genome amplification of low-copy-number DNA in chimerism analysis after allogeneic stem cell transplantation using STR marker typing.

Whole-genome DNA amplification (WGA) is a promising method that generates large amounts of DNA from samples of limited quantity. We investigated the accuracy of a multiplex PCR approach to WGA over STR loci. The amplification bias within a locus and over all analyzed loci was investigated in relation to the amount of template in the WGA reaction, the specific STR locus, and allele length. We observed reproducible error-free STR profiles with 10 ng down to 1 ng of DNA template. The amplification deviation at a locus and between loci was within the intra-method reproducibility. WGA is the method of choice for amplifying nanogram amounts of genomic DNA for different applications. We detected unbalanced STR amplifications at one locus and between loci, allelic drop-outs, and additional alleles after WGA of low-copy-number DNA. We found that the high number of drop-outs and drop-ins could be eradicated using pooled DNA from separate WGA reactions even with as little as 100 pg of starting template. Nevertheless, the quality of the results was still not sufficient for use in routine chimerism analysis of limited specific cell populations after allogeneic stem cell transplantation.

Allogeneic stem cell transplantation for patients with metastatic renal cell carcinoma.

Allogeneic stem cell transplantation and donor lymphocyte infusions are currently under clinical investigation as an innovative therapeutic option for patients with metastatic renal cell carcinoma. A variety of trials have proven the clinical efficacy of allogeneic stem cell transplantation using reduced-intensity conditioning protocols and donor lymphocyte infusions, as demonstrated by the induction of objective remissions in metastatic renal cell carcinoma patients. However, despite clinical remissions, reduced-intensity conditioning protocols and donor lymphocyte infusions were associated with a high treatment-related mortality rate of approximately 17%. The disproportion between clinical efficacy and treatment-related mortality may mainly be caused by the selection of patients that had often been heavily pretreated, with a large tumor burden and rapidly progressing tumors. The improvement of efficacy with the preservation of a powerful graft-versus-tumor effect while reducing the toxicity, is the major experimental and clinical challenge of allogeneic stem cell transplantation in the treatment of metastatic renal cancer and other solid tumors. Recently, there has been a revolutionary development of molecular-targeted agents in metastatic renal cancer. These inhibitors of angiogenesis and signal-transduction pathways have demonstrated clinical efficacy and significant survival prolongation in the first- and second-line settings, while causing moderate toxicity. Some of these agents have already been approved by the US FDA and will probably replace standard cytokines, such as interferon-alpha2 and interleukin-2, in metastatic renal cancer. In the context of these innovative clinical developments, allogeneic stem cell transplantation clearly has to be regarded an investigational clinical treatment approach. Therefore, patients should only be treated at centers that are experienced in clinical trials, and patient selection remains a critical factor for a successful transplant procedure.

Major histocompatibility complex HLA region largely explains the genetic variance exercised on neutrophil membrane proteinase 3 expression.

ANCA-associated vasculitides, a common cause of rapidly progressive glomerulonephritis, are influenced by genetic variance. Neutrophil membrane expression of the ANCA antigen proteinase 3 (PR3) is pathogenically important. A subset of membrane PR3-positive neutrophils can be distinguished from a membrane-negative subset in any given subject. The percentage of membrane PR3-positive neutrophils is genetically determined. In this study, 17 pairs of HLA-matched siblings were typed for their percentage of membrane PR3-positive neutrophils. The HLA-matched siblings showed a high concordance (r = 0.67, P < 0.05), similar to that seen in monozygotic twins. For testing of whether the HLA system influences membrane PR3 percentage, membrane PR3 typing and HLA typing of 51 unrelated patients with Wegener's granulomatosis and 49 normal control subjects was performed. Using two independent statistical methods, a group of 34 HLA antigens was found to predict a large fraction of the membrane PR3 phenotype in patients and control subjects. Certain major histocompatibility HLA antigens have been implicated to conflicting degrees in ANCA-associated vasculitides. However, in earlier studies, the contribution of the HLA system to the genetic variance of the disease was unclear. In this cohort, found was an association of Wegener's granulomatosis with the same group of HLA antigens that predicted for membrane PR3 percentage and a similar correlation with clinical parameters at initial presentation. The disease status in 80% of the patients and 82% of the control subjects could be predicted correctly on the basis of HLA typing by discriminate function analysis (P < 0.001). After removal of the predicted individual from the sample, this association remained significant (64 and 63% correct prediction; P < 0.001). The data suggest that a complex interaction of the entire HLA system is responsible for the genetic influence on membrane PR3 percentage and Wegener's granulomatosis.

The manuscript contains evidence-based recommendations for the assessment of the quality and strength of the data.

Nonmyeloablative allogeneic stem cell transplantation in metastatic renal cell carcinoma: a new therapeutic option or just a clinical experiment?

Nonmyeloablative stem cell transplantation (NST) and donor lymphocyte infusions (DLI) are currently under clinical investigation as an innovative therapeutic option for patients with metastatic renal cell carcinoma (RCC). The underlying concept, adopted from patients with hematologic malignancies, aims at a reduction of conditioning toxicity and exploits the graft versus malignancy effect of donor T-lymphocytes after transplantation. Clinical data from more than 100 patients treated worldwide have been published so far. The data provide evidence that NST is feasible with a very low rate of engraftment failure. Objective remissions in these heterogenous studies were observed in 23% of the patients overall. Remissions after NST developed only after complete engraftment of donor lymphoid cells had occurred. Objective responses were almost always accompanied by graft versus host disease (GvHD) after withdrawal of immunosuppression and/or DLI. GvHD and infections were the main contributors to a substantial transplant related morbidity and mortality, the major drawback of allogeneic stem cell transplantation. Therefore, clinical studies are necessary to further investigate and improve the selection of patients with metastatic RCC or other solid tumors for NST and to reduce post-transplant complications. This article reviews the results, side effects and potential future developments of NST in the treatment of solid tumors.

Prognostic factors for survival in patients with advanced renal cell carcinoma undergoing nonmyeloablative allogeneic stem cell transplantation.

BACKGROUND: The objective of this study was to identify prognostic factors for predicting survival in patients with advanced renal cell carcinoma (RCC) who had undergone an allogeneic stem cell transplantation after failure on immunotherapy. METHODS: The authors studied 70 patients with advanced RCC who underwent allogeneic transplantation with a fludarabine-based, reduced-intensity regimen. Ten parameters were analyzed at the time of transplantation for their power to predict survival. Clinical features were examined first univariately; then, variables that were correlated significantly with survival in the univariate analysis were included in a multivariate Cox regression model. RESULTS: Factors that were found to be associated significantly with limited survival were performance status, the number of metastatic sites, the presence of mediastinal metastasis, hemoglobin level, C-reactive protein (CRP) level, lactate dehydrogenase (LDH) level, and neutrophil counts. All these variables were included in a multivariate Cox regression model, and three were retained in the final model. Patients were classified according to the score estimated by the final Cox model in two groups (above or below the median value): The median survival was 3.5 months for patients who had a poor prognosis patients versus 23 months for patients who had a good prognosis. CONCLUSIONS: The current findings suggested that three easily available parameters (performance status, CRP level, and LDH level) could be used to stratify patients with advanced RCC who are candidates for allografting and to assist clinicians in decision-making and selection of an appropriate treatment program.
