RESUMO

Chronic lymphocytic leukemia (CLL) is the most common subtype of adult leukemia in the western world. We here report a nationwide survey monitoring the treatment decisions concerning CLL patients in Germany in 2011 and compare treatment trends to sequential surveys performed previously during the last decade. The rate of patients diagnosed in early stages (Binet A/B) notably increased (2006: 66 %, 2009: 71 %, 2011: 77 %) over the years. From 2006 to 2009, the most frequent applied regime switched from chlorambucil to fludarabine containing regimes (2006 chlorambucil: 32 %, 2009: 14 %, fludarabine 2006: 23 %, 2009: 37 %). In 2011, the combination of rituximab with bendamustine (31 %) was most frequent used followed by the rituximab-fludarabine-cyclophosphamide (22 %) regime. Further, immune-chemotherapies were administered significantly more often over the observation period (2006: 15 %, 2011: 73 %). Taken together, this data reflects the change of treatment strategies over the last decade in clinical reality.

RESUMO

Isavuconazole is a novel broad-spectrum triazole antifungal agent. This open-label dose escalation study assessed the safety and pharmacokinetics of intravenous isavuconazole prophylaxis in patients with acute myeloid leukemia who had undergone chemotherapy and had preexisting/expected neutropenia. Twenty-four patients were enrolled, and 20 patients completed the study. The patients in the low-dose cohort (n = 11) received isavuconazole loading doses on day 1 (400/200/200 mg, 6 h apart) and day 2 (200/200 mg, 12 h apart), followed by once-daily maintenance dosing (200 mg) on days 3 to 28. The loading and maintenance doses were doubled in the high-dose cohort (n = 12). The mean ± standard deviation plasma isavuconazole areas under the concentration-time curves for the dosing period on day 7 were 60.1 ± 22.3 µg · h/ml and 113.1 ± 19.6 µg · h/ml for the patients in the low-dose and high-dose cohorts, respectively. The adverse events in five patients in the low-dose cohort and in eight patients in the high-dose cohort were considered to be drug related. Most were mild to moderate in severity, and the most common adverse events were headache and rash (n = 3 each). One patient in the high-dose cohort experienced a serious adverse event (unrelated to isavuconazole treatment), and two patients each in the low-dose and high-dose cohorts discontinued the study due to adverse events. Of the 20 patients who completed the study, 18 were classified as a treatment success. In summary, the results of this analysis support the safety and tolerability of isavuconazole administered at 200 mg and 400 mg once-daily as prophylaxis in immunosuppressed patients at high risk of fungal infections. (This study is registered at ClinicalTrials.gov under registration number NCT00413439.).

RESUMO

The Infectious Diseases Working Party (AGIHO) of the German Society of Hematology and Oncology (DGHO) here presents its updated recommendations for the treatment of documented fungal infections. Invasive fungal infections are a main cause of morbidity and mortality in cancer patients undergoing intensive chemotherapy regimens. In recent years, new antifungal agents have been licensed, and agents already approved have been studied in new indications. The choice of the most appropriate antifungal treatment depends on the fungal species suspected or identified, the patient's risk factors (e.g., length and depth of neutropenia), and the expected side effects. This guideline reviews the clinical studies that served as a basis for the following recommendations. All recommendations including the levels of evidence are summarized in tables to give the reader rapid access to the information.

RESUMO

OBJECTIVES: To describe changes in costs of managing hospitalised patients with acute myeloid leukaemia (AML) after chemotherapy in Germany over 3 yr, with a special focus on prophylaxis and treatment patterns as well as resource use related to invasive fungal infections (IFI). METHODS: The study was conducted as a retrospective, single-centre chart review in patients with AML hospitalised for chemotherapy, neutropenia and infections after myelosuppressive chemotherapy from January 2004 to December 2006 in Germany. The following resource utilisation data were collected: inpatient stay, mechanical ventilation, parenteral feeding, diagnostics, systemic antifungal medication and cost-intensive concomitant medication. Direct medical costs were calculated from hospital provider perspective. RESULTS: A total of 471 episodes in 212 patients were included in the analysis. Occurrence of IFI decreased from 5.9% in 2004 to 1.9% in 2006. Mean (± standard deviation) hospital stay decreased from 28.7 ± 17.9 d in 2004 to 22.4 ± 11.8 d in 2006. From 2004 to 2006, the use of a single antifungal drug increased from 30.4% to 46.9%, whereas the use of multiple antifungal drugs decreased from 24.4% to 13.1%. The use of liposomal amphotericin B declined between 2004 and 2006 (21.4% vs. 3.8%) and caspofungin between 2005 and 2006 (19.3% vs. 8.1%). Total costs per episode declined from €19051 ± 19024 in 2004 to €13531 ± 9260 in 2006; major reductions were observed in the use of antimycotics and blood products as well as length of hospital stay. CONCLUSION: Analysis of real-life data from one single centre in Germany demonstrated a change in antifungal management of patients with AML between 2004/2005 and 2006, accompanied by a decline in total costs.

RESUMO

The treatment of hematologic patients in palliative situations remains a major challenge as there are special clinical needs, e.g., transfusions and the high risk for infectious complications with subsequent use of broad anti-infective treatment. Furthermore, most hematologic patients have a relatively long history of disease and are acquainted with "their" wards; that is why most are treated on these hematologic and not on specialized palliative wards. The standardized approach to the care of hematologic patients with curative treatment intention is probably not fully appropriate for palliative patients. In order to evaluate the current situation of treatment characteristics in a German university hospital, we retrospectively evaluated the medical documentation of all patients who died on a hematologic ward between 2005 and 2008. While we found a high number of chemotherapeutic, anti-infective, analgesic, and sedative treatments, of transfusions, of treatment on the intensive care units, and of invasive nature, non-somatic interventions were rather scarce. Symptom control, e.g., for bleeding events or pain, was frequently not adequately achieved. With regard to the palliative situation, a holistic approach with the maintenance of patients' autonomy and the preference for dying at home, the treatment of hematologic patients in a palliative situation has to be reconsidered.

RESUMO

Antifungal prophylaxis during first remission induction chemotherapy for acute myelogenous leukaemia requires broad spectrum azoles. In a clinical trial, therapeutic drug monitoring (TDM) of antifungal prophylaxis with voriconazole 200 mg bid was evaluated in a population of six patients. High pressure liquid chromatography was applied. Trough levels were obtained 24 h after the last voriconazole dose. Median time of voriconazole exposure prior to sample acquisition was 16 days (range 9-21). The mean voriconazole concentration was 486 µg l(-1) and ranged from 136 µg l(-1) to 1257 µg l(-1). Among possible or probable treatment-related adverse events, elevated liver function tests were the most frequent. Five of six patients developed fever during neutropenia, but none of them developed pulmonary infiltrates or other signs of invasive fungal infection while on voriconazole prophylaxis. Future investigations might aim at identifying drug level thresholds that allow for minimum toxicity and optimum efficacy of antifungal prophylaxis.

RESUMO

There is no widely accepted standard for antifungal prophylaxis in patients with hematologic malignancies. The Infectious Diseases Working Party of the German Society for Haematology and Oncology assigned a committee of hematologists and infectious disease specialists to develop recommendations. Literature data bases were systematically searched for clinical trials on antifungal prophylaxis. The studies identified were shared within the committee. Data were extracted by two of the authors (OAC and MSi). The consensus process was conducted by email communication. Finally, a review committee discussed the proposed recommendations. After consensus was established the recommendations were finalized. A total of 86 trials were identified including 16,922 patients. Only a few trials yielded significant differences in efficacy. Fluconazole 400 mg/d improved the incidence rates of invasive fungal infections and attributable mortality in allogeneic stem cell recipients. Posaconazole 600 mg/d reduced the incidence of IFI and attributable mortality in allogeneic stem cell recipients with severe graft versus host disease, and in patients with acute myelogenous leukemia or myelodysplastic syndrome additionally reduced overall mortality. Aerosolized liposomal amphotericin B reduced the incidence rate of invasive pulmonary aspergillosis. Posaconazole 600 mg/d is recommended in patients with acute myelogenous leukemia/myelodysplastic syndrome or undergoing allogeneic stem cell recipients with graft versus host disease for the prevention of invasive fungal infections and attributable mortality (Level A I). Fluconazole 400 mg/d is recommended in allogeneic stem cell recipients until development of graft versus host disease only (Level A I). Aerosolized liposomal amphotericin B is recommended during prolonged neutropenia (Level B II).

RESUMO

Invasive fungal infections are a main cause of morbidity and mortality in cancer patients undergoing intensive chemotherapy regimens. Early antifungal treatment is mandatory to improve survival. Today, a number of effective and better-tolerated but more expensive antifungal agents compared to the former gold standard amphotericin B deoxycholate are available. Clinical decision-making must consider results from numerous studies and published guidelines, as well as licensing status and cost pressure. New developments in antifungal prophylaxis improving survival rates result in a continuous need for actualization. The treatment options for invasive Candida infections include fluconazole, voriconazole, and amphotericin B and its lipid formulations, as well as echinocandins. Voriconazole, amphotericin B, amphotericin B lipid formulations, caspofungin, itraconazole, and posaconazole are available for the treatment of invasive aspergillosis. Additional procedures, such as surgical interventions, immunoregulatory therapy, and granulocyte transfusions, have to be considered. The Infectious Diseases Working Party of the German Society of Hematology and Oncology here presents its 2008 recommendations discussing the dos and do-nots, as well as the problems and possible solutions, of evidence criteria selection.

RESUMO

Although various guidelines on antifungal prophylaxis and treatment have been published, the practical approach in the individual clinical setting might considerably differ because of special local circumstances. In addition, there are major differences between paediatric and adult patients regarding antifungal strategies and the use of antifungal compounds. We here present the antifungal approach in the Departments of Hematology and Oncology of the University Hospital of Frankfurt, where per year approximately 350 children and adults are diagnosed with cancer and an additional 100 patients undergo haematopoietic stem cell transplantation. The differences in the approach between the paediatric and adult setting are highlighted.

RESUMO

BACKGROUND: Intensive chemotherapy with severe neutropenia is associated with invasive fungal infections (IFIs) leading to high mortality rates. During leukaemia induction chemotherapy, IFI often prohibited further curative treatment, thus predisposing for leukaemia relapse. Continuing myelosuppressive chemotherapy after diagnosis of IFI has become feasible with the now expanding arsenal of safe and effective antifungals. Secondary prophylaxis of IFI is widely administered, but reliable data on outcome and risk factors for recurrent IFI during subsequent chemotherapy are not available. This study determines risk factors for recurrent IFI in leukaemia patients. METHODS: From 25 European cancer centres, 166 consecutive patients with acute myelogenous leukaemia (AML) and a recent history of proven or probable pulmonary IFI were included. Patients were followed for recurrence or breakthrough IFI during the subsequent chemotherapy cycle. RESULTS: Of the 166 patients included, 69 (41.6%) were female, the median age was 53 years (range 2-81) the and 3 (1.8%) were <16 years. Recurrent IFI occurred in 26 patients (15.7%). Multiple logistic regressions yielded predisposing factors: duration of neutropenia [per additional day; odds ratio (OR) 1.043, confidence interval (CI) 1.008-1.078], high-dose cytarabine (OR 3.920, CI 1.120-12.706), number of antibiotics (per antibiotic; OR 1.504, CI 1.089-2.086), partial response as outcome of prior IFI (OR 4.037, CI 1.301-12.524) and newly diagnosed AML (OR 3.823, CI 0.953-15.340). Usage of high efficiency particulate air filter appeared protective (OR 0.198, CI 0.036-1.089). CONCLUSIONS: Duration of neutropenia, high-dose cytarabine, prior antibiotic therapy and a partial response to the first IFI therapy were risk factors for recurrent IFI and should be considered in AML patients with prior pulmonary IFI undergoing further chemotherapy.

RESUMO

Invasive fungal infections are frequent and often deadly complications in patients with malignant hematological diseases. Voriconazole is a third generation triazole antifungal with broad activity against most clinically relevant fungal pathogens. Clinical practice often deviates from insights gained from controlled randomized trials. We conducted a multi-centre survey to evaluate efficacy, safety, treatment indications and dosing of voriconazole outside clinical trials. Patients receiving voriconazole were documented via electronic data capturing. An analysis was conducted after submission of 100 episodes from September 2004 to November 2005. Voriconazole was administered for suspected or proven invasive fungal infection (IFI) (57%), as empirical treatment in patients with fever of unknown origin (21%) and secondary (19%) as well as primary (3%) prophylaxis of IFI. Investigators' assessment of fungal infection often diverted from EORTC/MSG 2002 criteria. A favorable response was reported in 61.4% for suspected or proven IFI and 52.4% for empirical treatment. Mortality was 15%, 26.7% of which was attributable to IFI. Breakthrough fungal infections occurred in four (21.1%) patients with voriconazole as secondary prophylaxis. Toxicity and adverse events comprised elevated liver enzymes and visual disturbances. Although indications frequently deviated from clinical evidence and legal approval, voriconazole showed efficacy and safety, comparable to major controlled clinical trials. Data from this survey demonstrate the difficulty of putting drugs to their approved use in IFI.

RESUMO

The gold standard of cytogenetic analysis in myelodysplastic syndromes (MDS) is conventional chromosome banding (CCB) analysis of bone marrow (BM) metaphases. Most aberrations can also be detected by fluorescence-in situ-hybridization (FISH). For this prospective multicenter German diagnostic study (www.clinicaltrials.gov: #NCT01355913) 360 patients, as yet, were followed up to 3 years by sequential FISH analyses of immunomagnetically enriched CD34+ peripheral blood (PB) cells using comprehensive FISH probe panels, resulting in a total number of 19,516 FISH analyses. We demonstrate that CD34+ PB FISH correlates significantly with CCB analysis and represents a feasible method for a reliable non-invasive cytogenetic monitoring from PB.

RESUMO

OBJECTIVE: Invasive fungal infections (IFIs) are an important cause of morbidity and mortality, particularly in patients with cancer. The triazole voriconazole, given as oral or intravenous formulation, has a high bioavailability and proven efficacy against invasive aspergillosis, candidiasis and other fungi. We aimed to assess the utilisation, efficacy and safety of voriconazole with emphasis on the route of administration under standard clinical conditions. METHODS: Prospective, observational study performed by 17 hospitals and office-based physicians in Germany. RESULTS: A total of 264 patients received oral (53%) or intravenous (22%) voriconazole or both formulations sequentially (25%). Of 228 patients with specified fungal diagnosis, 95 (36.0%) had aspergillosis, 73 (27.7%) candidiasis. Sixty (22.7%) received voriconazole for other fungal indications (OFI). In 195 of 226 patients (86.2%), treatment was successful (39.8% cured and 46.5% partial response). In terms of primary diagnoses, favourable responses were noted in 90% for pulmonary aspergillosis, 85% for candidiasis and 87% for OFI. Microbiological success was documented in 138 patients, of whom 105 (76.1%) had complete eradication of fungi. Response rates by initial route were similar for oral and intravenous administration (86 and 87%). Twenty-six of 264 patients died during the study, 53 patients experienced a serious adverse event (five treatment related), and 10 withdrew due to all-causality adverse events (AEs). Tolerability was assessed as very good in 55%, and good in 40% of patients. CONCLUSIONS: Voriconazole as oral or intravenous formulation was well tolerated and equally effective in critically ill patients with IFIs. This study in daily care confirms the outcomes of controlled clinical trials.

RESUMO

Type 1 diabetes (T1D) is a T-cell-mediated autoimmune disease. Although the precise mechanisms leading to the destruction of islet beta cells are unknown, diverse studies support a role of the CXCR3-binding chemokines. A combination of a case (n = 447)-control (n = 300) and family (n = 221) analysis was performed to investigate the role of the CXCL9 (rs10336, rs3733236) and CXCL10 (rs3921, rs35795399 and rs8878) polymorphisms and their interaction with HLA high-risk haplotypes DQ2(DQA*0501-DQB*0201)-DQ8(DQA*0301-DQB*0302) in T1D. In addition, the mRNA expression of these genes and of the CXCR3 in peripheral blood mononuclear cells (PBMCs) of T1D patients was studied. In the family analysis, an overtransmission of the allele T and G of the polymorphisms rs35795399 and rs8878 in the whole group (p = 0.0520 and p = 0.0290, respectively) as well as in combination with the HLA-high risk haplotypes (p = 0.0209 and 0.0340, respectively) were observed. In addition, the haplotype rs8878G-rs35795399T was more often transmitted from parents to affected offspring, whereas the haplotype rs8878A-rs35795399C was less often transmitted (p = 0.0130 and p = 0.0201, respectively). Nevertheless these associations did not remain significant after correction for multiple testing, and they could not be corroborated in the case-control analysis. Although we did not find an association of the CXCL9 and CXCL10 polymorphisms with type 1 diabetes in the German population, we cannot discard their role in other populations or other autoimmune diseases.

RESUMO

Patients surviving invasive fungal disease (IFD) and needing further antineoplastic chemotherapy are at high risk of recurrent fungal infection. In the absence of randomised controlled trials in this area, secondary prophylactic regimens are diverse. From 448 patients registered with the Multinational Case Registry of Secondary Antifungal Prophylaxis, we performed an analysis of patients receiving caspofungin (CAS) or itraconazole (ITC). All patients had an underlying haematological malignancy and had been diagnosed with an episode of IFD earlier in their course of treatment. Data collected comprised demographics, underlying disease, first episode of IFD, antifungal prophylaxis, incidence and outcome of breakthrough IFD and survival. A total of 75 patients were evaluated, comprising 28 receiving CAS and 47 receiving ITC. Patients in the CAS group were more likely to have had progression of underlying disease (32.1% vs. 8.5%; P=0.028) as well as incomplete response of initial IFD at baseline (85.7% vs. 57.4%; P=0.005). Allogeneic stem cell transplantation was more prevalent in patients receiving CAS (46.4% vs. 14.9%; P=0.010). There was no difference in the occurrence of breakthrough IFD between both groups (32.1% vs. 31.9%). Treatment outcomes for recurrent IFD and overall mortality did not differ between groups. Both ITC and CAS were equally effective in preventing second episodes of IFD. Patients with uncontrolled first IFD, uncontrolled underlying disease or those receiving stem cell transplantation were more likely to have received CAS prophylaxis. Despite antifungal prophylaxis, risk of breakthrough IFD was high in both groups.

RESUMO

TIM-3 is a transmembrane protein preferentially expressed on differentiated Th1 cells, which play a role in Th1-mediated diseases including type 1 diabetes. We investigated the role of the rs10515746 (A/C), rs1036199 (A/C), and rs10053538 (A/C) single nucleotide polymorphisms (SNPs) within the TIM-3 gene in 186 German type 1 diabetes families (558 individuals) and its interaction with human leukocyte antigen (HLA) high-risk haplotypes DQ2(DQA*0501-DQB*0201)-DQ8 (DQA*0301-DQB*0302). Alleles A, C, and A of the rs10515746 (A/C), rs1036199 (A/C), and rs10053538 (A/C) SNPs were found in a frequency of 20.4%, 19.0%, and 4.2%, respectively. Transmission analysis of these polymorphisms did not show any significant difference. Although in patients with HLA DQx/x (neither HLA DQ2 nor DQ8) an undertransmission of allele A (14.3% vs. 85.7%) of the rs10053538 (A/C) SNP and an overtransmission of allele A (66.7% vs. 33.3%) of the rs10515746 (A/C) SNP was observed, these associations did not remain statistically significant after correction for multiple comparisons. Although we found no association of TIM-3 with type 1 diabetes in the German population, we cannot discard a possible association in a larger size.

RESUMO

BACKGROUND: Safety, tolerability and efficacy of itraconazole and amphotericin B (AMB) were compared for empirical antifungal treatment of febrile neutropenic cancer patients. PATIENTS AND METHODS: In an open, randomised study, 162 patients with at least 72 h of antimicrobial treatment received either intravenous followed by oral itraconazole suspension or intravenous AMB for a maximum of 28 days. Permanent discontinuation of study medication due to any adverse event was the primary safety parameter. Efficacy parameters included response and success rate for both treatment groups. RESULTS: Significantly fewer itraconazole patients discontinued treatment due to any adverse event (22.2 vs. 56.8% AMB; p < 0.0001). The main reason for discontinuation was a rise in serum creatinine (1.2% itraconazole vs. 23.5% AMB). Renal toxicity was significantly higher and more drug-related adverse events occurred in the AMB group. Intention-to-treat (ITT) analysis showed favourable efficacy for itraconazole: response and success rate were both significantly higher than for AMB (61.7 vs. 42% and 70.4 vs. 49.3%, both p < 0.0001). Treatment failure was markedly reduced in itraconazole patients (25.9 vs. 43.2%), largely due to the better tolerability. CONCLUSIONS: Itraconazole was tolerated significantly better than conventional AMB and also showed advantages regarding efficacy. This study confirms the role of itraconazole as a useful and safe agent in empirical antifungal therapy of febrile neutropenic cancer patients.

RESUMO

OBJECTIVES: Invasive fungal infections remain a frequent cause of morbidity and mortality in long-term neutropenic patients. The availability of tolerable broad-spectrum antifungals like voriconazole stimulated the discussion about optimal timing of antifungal therapy. We conducted a trial to analyze the efficacy and safety of voriconazole in the prevention of lung infiltrates during induction chemotherapy for acute myelogenous leukaemia (AML). METHODS: This was a prospective, randomised, double-blind, placebo-controlled phase III trial in AML patients undergoing remission induction chemotherapy. Oral voriconazole 200 mg twice daily or placebo was administered until detection of a lung infiltrate or end of neutropenia. Primary efficacy parameter was the incidence of lung infiltrates until day 21 after initiation of chemotherapy. Secondary objectives were incidence of infections, length of stay in hospital, time to antifungal treatment, time to first fever, and drug safety. RESULTS: A total of 25 patients were randomly assigned to receive voriconazole (N=10) or placebo (N=15). Incidence of lung infiltrates until day 21 was 0 (0%) in the voriconazole and 5 (33%) in the placebo group (P=0.06). Average length of stay in hospital was shorter in the voriconazole group (mean 31.9 days) than in the placebo group (mean 37.3 days, P=0.09). Four patients were diagnosed with hepatosplenic candidiasis until a 4 week follow-up, all in the placebo group (P=0.11). Adverse events and toxicity did not differ between the two treatment groups. The trial was stopped prematurely when another trial demonstrated reduced mortality by antifungal prophylaxis with posaconazole, thus rendering further randomisation against placebo unethical. CONCLUSION: In AML patients undergoing induction chemotherapy, prophylactic oral voriconazole 200 mg twice daily resulted in trends towards reduced incidences of lung infiltrates and hepatosplenic candidiasis. Voriconazole was safe and well tolerated.

RESUMO

Patients with haematological malignancies and prolonged periods of neutropenia after chemotherapy are at high risk for severe bacterial and fungal infections. Those infections have long time been considered as a contraindication for subsequent haematopoietic stem cell transplantation (HCT). We conducted a prospective, non-randomized study of granulocyte transfusions (GTX) to control acute life-threatening infections (44 episodes) and to prevent recurrence of severe fungal infections during HCT or intensive chemotherapy (23 episodes). GTX achieved control in 82% (36/44) of acute life-threatening infections. No single reactivation of a previous infection occurred under prophylactic GTX (0/23). Median survival was 170 days in the interventional group and 185 days in the prophylactic group; death in both patient groups was mainly due to underlying progressive malignant disease. We conclude that under GTX, the infection-related mortality even in high-risk patients is low. Due to a secondary prophylaxis with GTX, haematopoietic allografts can be safely given to patients with previous fungal infections.
