Epidemiology, patient adherence, and costs of oral mucositis in routine care in stem cell transplantation.

PURPOSE: Limited data about oral mucositis (OM) in stem cell transplant patients with underlying hematological disease is available in Germany. The purpose of this feasibility study was to determine the incidence, treatment patterns, patients' adherence, and costs of OM. METHODS: Prospective, noninterventional single-center observational study. INCLUSION CRITERIA: allogenic/autologous stem cell transplant patients ≥ 18 years, high-dose chemotherapy. OM assessment: WHO Oral Toxicity Scale. Adherence was measured in patient interviews. Preventive and therapeutic measures were extracted from patients' charts. RESULTS: Forty-five patients (25 allogenic, 20 autologous) were enrolled. Twenty-six (58%) patients developed OM (54% grade I/II, 46% grade III/IV). Age ≥ 65 (31% vs 69%, p = 0.021) was associated with a lower OM incidence. A positive history of smoking (1.77 vs 2.69, p = 0.036) was associated with a lower OM grade, patients with unrelated donors (2.63 vs 1.29, p = 0.014) were associated with higher OM grades and females (80% vs 47%, RR = 1.71, p = 0.035) with a higher incidence. OM patients were less adherent to recommended daily mouth rinses (35% vs 68%, p = 0.027). More analgesic treatment (80% vs 32%, p = 0.001) and intravenous opioids (24% vs 0%, p = 0.023) were prescribed in OM patients. Total drug treatment and nutrition costs were 824€ (p = 0.037) higher in autologous transplanted patients. CONCLUSION: Initial risk and consecutive OM assessment, determination of patients' adherence, resource consumption, and costs are prerequisites to evaluate OM care. In the best case, several centers will follow the same methodological approach and the collected data will serve as a basis for benchmarking analyses to optimize OM care where required.

Plerixafor in non-Hodgkin's lymphoma patients: a German analysis of time, effort and costs.

Mobilization and collection of peripheral blood stem cells is part of the standard treatment procedure for non-Hodgkin's lymphoma patients eligible for high-dose chemotherapy with autologous stem cell transplantation. Mobilization is usually achieved with chemotherapy and/or cytokines, but plerixafor might be added in case of poor mobilization. Due to the high cost several institutions have developed their own management pathway to optimize use of plerixafor. Such models are however rarely generalizable; in a multi-center, European, non-interventional study, evaluating the impact of plerixafor in poor mobilizers, country specific differences in patient treatment and cost structure were obvious. For German centers, there was a non-significant reduction in the number of apheresis sessions carried out and in apheresis costs. In contrast to other European countries the majority of German Plerixafor patients were very poor mobilizing patients with initial CD34+ cell count ≤ 10/µl (40/51). In this group the number of apheresis sessions decreased from 2.1 to 1.6 sessions per patient (p = 0.01) and costs decreased from €6246 to €4758 (p = 0.01). Our results show that preemptive plerixafor use has a strong effect in poor mobilizers with an initial CD34+ cell count ≤ 10 cells/µl.

Diagnosis and empirical treatment of fever of unknown origin (FUO) in adult neutropenic patients: guidelines of the Infectious Diseases Working Party (AGIHO) of the German Society of Hematology and Medical Oncology (DGHO).

Fever may be the only clinical symptom at the onset of infection in neutropenic cancer patients undergoing myelosuppressive chemotherapy. A prompt and evidence-based diagnostic and therapeutic approach is mandatory. A systematic search of current literature was conducted, including only full papers and excluding allogeneic hematopoietic stem cell transplant recipients. Recommendations for diagnosis and therapy were developed by an expert panel and approved after plenary discussion by the AGIHO. Randomized clinical trials were mainly available for therapeutic decisions, and new diagnostic procedures have been introduced into clinical practice in the past decade. Stratification into a high-risk versus low-risk patient population is recommended. In high-risk patients, initial empirical antimicrobial therapy should be active against pathogens most commonly involved in microbiologically documented and most threatening infections, including Pseudomonas aeruginosa, but excluding coagulase-negative staphylococci. In patients whose expected duration of neutropenia is more than 7 days and who do not respond to first-line antibacterial treatment, specifically in the absence of mold-active antifungal prophylaxis, further therapy should be directed also against fungi, in particular Aspergillus species. With regard to antimicrobial stewardship, treatment duration after defervescence in persistently neutropenic patients must be critically reconsidered and the choice of anti-infective agents adjusted to local epidemiology. This guideline updates recommendations for diagnosis and empirical therapy of fever of unknown origin in adult neutropenic cancer patients in light of the challenges of antimicrobial stewardship.

Applicability of the EORTC/MSG criteria for IFD in clinical practice.

Invasive fungal disease (IFD) is a feared complication in patients with hematological malignancies. In 2008, the European Organization for Research and Treatment of Cancer/Invasive Fungal Infections Cooperative Group and the National Institute of Allergy and Infectious Diseases Mycosis Study Group (EORTC/MSG) published updated criteria for the diagnostic workup within clinical studies for immunosuppressed patients with suspected fungal infection. We applied these criteria in a routine clinical setting with regard to their feasibility for bedside practice at our institution in a 1-year period. One hundred seventy consecutive patients with a recent history of chemotherapy-induced neutropenia (n = 100) or allogeneic stem cell recipients (n = 70) who had received a CT scan of the chest in search of pulmonary IFD were examined. We analyzed all available radiological and microbiological data according to the EORTC/MSG criteria. The quality of images was good in 94.7%, microbiological diagnostics performed in 94.1% patients. Five patients had histopathologic-proven IFD, 18 patients were classified as "probable," 55 patients as "possible" IFD, and 92 patients did not fulfill any criteria ("no IFD"). Microbiology revealed suggestive findings in 29 patients. These were either galactomannan antigen (Gm-AG) in serum (n = 18) and/or broncho-alveolar lavage (BAL) (n = 5). CT scan showed pulmonary infiltrates in 106 patients; 78 were classified as typical for IPA, further discriminated by morphology and number of nodules, as well as additional signs (halo, air crescent, cavity). We observed a better overall survival in patients without infiltrates compared to those with any type of infiltrate (p = 0.042) and a trend toward favorable survival in patients who had micronodular lesions (p = 0.058). We also found a higher probability of Gm-AG positivity in the group of allogeneic stem cell transplantation (allo-SCT) patients (p = 0.001) and a trend toward an association of Gm-AG positivity and positive findings on CT (p = 0.054). The applicability of criteria was good, both with regard to radiological and mycological evidence and sufficient for the categorization of IFD according to EORTC/MSG in the clinical setting. However, our findings suggest that feasibility improves with stringency of mycological workup, which is reflected in the two subgroups. Radiology harvests by far more suggestive findings which can only partly be correlated with mycological evidence. Although feasible, whether the EORTC/MSG criteria are the appropriate tool for early identification of IFD remains open for discussion.

Current management of patients hospitalized with complicated skin and soft tissue infections across Europe (2010-2011): assessment of clinical practice patterns and real-life effectiveness of antibiotics from the REACH study.

Complicated skin and soft tissue infections (cSSTI) are common and frequently require treatment in hospital. Comprehensive current data on management practices in patients hospitalized with cSSTI are limited. REACH was a retrospective, observational cohort study designed to provide data on current clinical management of moderate to severe cSSTI in European hospitals. Data were collected via an electronic case report form from 129 sites in ten European countries. The study population comprised patients ≥18 years, hospitalized between March 2010 and February 2011 with cSSTI who received intravenous antibiotic treatment. Presented here is an analysis of the disease characteristics, treatment patterns during hospitalization and clinical outcomes identified by the study. The total population included 1995 patients (mean age 60.6 years; 57.7% male). Initial antibiotic treatment modification was reported in 39.6% (n = 791) of patients; it was more common in patients with co-morbidities (42.6%), those requiring surgical intervention (43.4%), those with more severe infections such as bacteraemia (51.6%) or with fascia affected (49.0%), those admitted to the intensive care unit (56.2%) and those with lesions > 50 cm(2) (44.3%). A switch to narrower-spectrum antibiotic treatment (streamlining) occurred in 5.6% of patients. Mean length of hospital stay was 18.5 days (±19.9; median 12.0) and the total mortality rate was 3.4%. The data collected in REACH give a comprehensive and current view of real-life clinical management of cSSTI in European hospitals and provide evidence of a high rate of initial antibiotic treatment modification.

[The tumor patient with an indication for intensive anticoagulation]. / Der Tumorpatient mit gleichzeitiger Indikation zur intensiven Antikoagulation.

Patients with cancer are at high risk to develop venous thromboembolism as well as arterial thrombosis. Well established treatment patterns of these vascular complications are often hampered in cancer patients by disturbances of coagulation or thrombocytopenia. Therefore standardized interventions or medical treatment can be difficult to perform. As data from clinical trials or recommendations from guidelines are sparse, complicated cases have to be dealt with an interdisciplinary single patient approach. Thus in patients with STEMI application of a drug eluting stent which might be the best treatment in a non-cancer patient may not be feasible. In cancer patients with venous thromboembolism and bleeding the implantation of a vena cava filter might be necessary.

Treatment cost of invasive fungal disease (Ifd) in patients with acute myelogenous leukaemia (Aml) or myelodysplastic syndrome (Mds) in German hospitals.

Invasive fungal disease (IFD) causes increasing morbidity and mortality in haematological cancer patients. Reliable cost data for treating IFD in German hospitals is not available. Objective of the study was to determine the institutional cost of treating the IFD. Data were obtained by retrospective chart review in German hospitals. Patients had either newly diagnosed or relapsed acute myeloid leukaemia (AML) or myelodysplastic syndrome (MDS). Direct medical cost was calculated from hospital provider's perspective. A total of 108 patients were enrolled at 5 tertiary care hospitals, 36 IFD patients and 72 controls. The vast majority of IFD patients (74%) were diagnosed with invasive aspergillosis. On average, the hospital stay for IFD patients was 12 days longer than in control patients. All patients in the IFD group and 89% of patients in the control group received antifungal drugs. Mean direct costs per patient were €51,517 in the IFD group and €30,454 in the control group. Incremental costs of €21,063 were dominated by cost for antifungal drugs (36%), hospital stay (32%) and blood products (23%). From the perspective of hospitals in Germany the economic burden of IFD in patients with AML or MDS is substantial. Therefore, prevention of IFD is necessary with respect to both clinical and economic reasons.

Current issues in the clinical management of invasive candida infections--the AGIHO, DMykG, ÖGMM and PEG web-based survey and expert consensus conference 2009.

The objectives of this study were to identify unsolved issues in the management of invasive candidiasis, identify controversies and achieve consensus. The German Speaking Mycological Society (Deutschsprachige Mykologische Gesellschaft, DMykG e.V.) asked other German infectious diseases (ID) and mycological societies to submit unsolved issues concerning the diagnosis and treatment of fungal infections. Based on these contributions, a digital web-based questionnaire of 12 questions on Candida infections was designed to be completed by experts of the participating societies. Controversial results were identified by a mathematical model and were discussed at a consensus conference during the 43rd Annual Meeting of the DMykG e.V. in Cologne, Germany. Forty-two individuals completed the questionnaire. Analysis showed a strong consensus on treatment indications, choice of antifungals for clinical situations, handling of central venous catheters, duration of treatment and role of susceptibility testing. Opinions diverged on: initial treatment of haemodynamically stable neutropenic and haemodynamically unstable non-neutropenic patients, step down to oral treatment and the differential role of the echinocandins. These questions were presented for discussion at the expert consensus conference. In three of four questions, consensus was achieved. A two-step approach - web-based survey plus classical panel discussion - allows to capture expeditiously the opinions of a large and diverse group of individuals, to identify controversial issues and to resolve them in a personal, interactive setting. Thus, expert consensus was achieved on nine of 12 important questions on how to treat invasive candidiasis.

The objectives of this study were to identify unsolved issues in the management of invasive aspergillosis, identify controversies and achieve consensus. The German Speaking Mycological Society (Deutschsprachige Mykologische Gesellschaft, DMykG) invited other German infectious diseases (ID) and mycological societies to submit unsolved issues concerning the diagnosis and treatment of invasive aspergillosis. Based on these contributions, a digital web-based questionnaire of 12 questions on Aspergillus spp. was designed to be completed by experts of the participating societies. Controversial results were identified by a mathematical model and were discussed at a consensus conference during the 43rd Annual Meeting of the DMykG in Cologne, Germany. Forty-two individuals completed the questionnaire. Analysis showed a strong consensus on effective preventive measures, choice of antifungal agents for pre-emptive, empiric and targeted treatment, as well as the evaluation of early chest CT control scans as a measure of treatment response assessment. Opinions on the indication for a pulmonary biopsy of a halo sign in high-risk neutropenic patients and on the role of Aspergillus spp. PCR as well as galactomannan from serum in the assessment of treatment duration diverged in spite of discussion such that a consensus could not be reached. Using a recently published two-step approach - web-based survey plus classical panel discussion - expert consensus was achieved on 10 of 12 questions concerning the diagnosis and treatment of invasive aspergillosis.

[Therapy-refractory thrombocytopenia in a 28-year-old patient]. / Therapierefraktäre Thrombozytopenie bei einem 28-jährigen Patienten.

We report a case of a patient with thrombocytopenia. A sporadic MYH9-associated disease, May Hegglin anomaly, was identified by giant platelets, leucocyte inclusion bodies and the typical distribution of NMMHC-IIA in granulocytes in the absence of impaired renal function, cataract and hearing loss. MYH9-associated diseases are an underestimated differential diagnosis of idiopathic thrombocytopenia. The correct diagnosis is important to prevent unnecessary treatment of a patient with thrombocytopenia and to provide sufficient patient information and genetic counseling. Therefore, careful examination of the blood smear has to be the first diagnostic step in a case of unexplained thrombocytopenia.

Management of sepsis in neutropenic patients: guidelines from the infectious diseases working party of the German Society of Hematology and Oncology.

Sepsis is a leading cause of mortality in neutropenic cancer patients. Early initiation of effective causative therapy as well as intensive adjunctive therapy is mandatory to improve outcome. We give recommendations for the management of adults with neutropenia and sepsis. The guidelines are written for clinicians involved in care of cancer patients and focus on pathophysiology, diagnosis and treatment of sepsis during neutropenia.

[Fever of unknown origin in malignancies]. / Fieber unklarer Genese bei malignen Erkrankungen.

Fever is a common symptom in patients with malignancies. On the one hand it may be an (initial) symptom of cancer, on the other hand it may occur as a side effect of chemotherapy. Often a precise cause of fever can not be established and in these cases febrile temperatures >38.3 degrees C without proof of infection or relapse/progress of tumor is defined as fever of unknown origin. Especially hematologic neoplasias are accompanied by fever. Here, neoplastic fever must be distinguished from fever following immunosuppressive chemotherapy. In the latter severe infections due to neutropenia induced by cytoreductive chemotherapy is often identified as the cause of fever. These patients display a high morbidity and mortality, especially if an empiric anti-infectious treatment is not administered in time. A meticulous diagnostic work-up is therefore necessary, and until proven otherwise, an infectious cause must be considered and empiric antibiotic treatment initiated.

Infectious complications after allogeneic stem cell transplantation: incidence in matched-related and matched-unrelated transplant settings.

BACKGROUND: Bacterial, viral, and fungal pathogens frequently cause severe, life-threatening infections in immunocompromised patients after allogeneic hematopoietic stem cell transplantation (SCT). OBJECTIVE: To compare the frequency of infections in patients with matched-related (Group A) or with human leukocyte antigen (HLA)-matched-unrelated donors (Group B). PATIENTS AND METHODS: Patients treated at our transplantation unit between April 2004 and April 2005 were enrolled into this analysis. Documentation comprised demographic data, conditioning treatment, stem cell source, clinical course, as well as microbiological and clinical data and mortality. RESULTS: We analyzed 59 patients, 22 in Group A and 37 in Group B. Both groups were well balanced regarding demographic data. Diagnoses were acute myeloid leukemia (30 of 59 patients, 50.8%), multiple myeloma (15.2%), acute lymphoblastic leukemia (11.9%), and chronic myeloid leukemia (10.2%). Patients in Group A developed infections in 95.5% of the cases compared with 97.3% in patients in Group B. Most frequently detected pathogens were Staphylococcus species, human herpesvirus-6, and Epstein-Barr virus. Three proven fungal infections were detected in Group A compared with 9 proven fungal infections in Group B. Lung infiltrations were observed in equivalent incidence in both groups. Two years after transplantation, 55.9% of patients were alive (Group A: 68.2%; Group B: 48.6%, not significant). CONCLUSION: Allogeneic SCT from HLA-matched-unrelated donors does not have a higher infection risk than patients transplanted from matched-related donors.

[Severe sepsis and disseminated intravascular coagulation. Supplementation with antithrombin]. / Schwere Sepsis und disseminierte intravasale Gerinnung. Substitution von Antithrombin.

Administration of high-dose antithrombin (AT) was investigated on a large collective of patients with severe sepsis in the KyberSept study. In the total study the administration of AT resulted in no significant reduction of the mortality rate in comparison to a placebo. However, in the protocol of this study subgroups were predefined, which when analyzed revealed that the group of patients who received AT but not simultaneously heparin did show a reduction of the mortality rate in comparison to the placebo group. The reduction of the absolute mortality rate of 15% reached statistical significance on day 90. Even patients classified as risk group grade II according to the Simplified Acute Physiology Score (SAPS), showed a significant reduction of the mortality rate of approximately 22% after 90 days without simultaneous administration of heparin. Such a positive result for administration of AT without simultaneous heparin treatment can also be found when severe sepsis complicated by disseminated intravascular coagulation (DIC) is present. Coagulation diagnostic assists the recognition of latent or fulminant DIC and also in surveillance of the course and development. The results of AT supplementation for severe sepsis and DIC are in agreement with earlier studies on smaller patient collectives and suggest that a randomized controlled clinical study should be carried out on a subcollective of severely ill patients.

Plesiomonas shigelloides pneumonia.

Plesiomonas shigelloides is known to cause mild to cholera-like diarrhea in most infected persons. In immunocompromised patients extra-intestinal manifestations have been described. We report the first case of pneumonia caused by P. shigelloides in a 76-year-old woman who had undergone a curative gastrectomy and esophageal-jejunostomy due to a low differentiated adenocarcinoma of the stomach (pT2, pN1 pMx, G3, R0, Lauren: intestinal type). The patient was admitted in hospital with clinical signs of pulmonary infection. CT-scan revealed a cavernous lesion in the right upper pulmonary lobe. Bronchial lavage showed a granulocytic inflammation 105CFU/ml P. shigelloides. Although antibiotic treatment led to a decrease of inflammation parameters and decrease of the pulmonary infiltrate the patient died due to development of torsades de pointes tachycardia leading to ventricular fibrillation and hypoxic brain damage.

Impact of robotic dispensing machines in german pharmacies on business performance indicators.

AIMS AND OBJECTIVES: To assess the impact of robotic dispensing machines in community pharmacies on staff efficiency and sales of over-the-counter drugs. SETTING: The study was done on 253 community pharmacies in Germany that use a robotic dispensing machine manufactured by ROWA during 2008. METHOD: Data concerning the financial and economic impact of using a robotic dispensing machine in community pharmacies was gathered using a structured questionnaire and analysed in terms of its financial implications. KEY FINDINGS: The response rate was 29%. In most pharmacies (79%) the robotic dispensing machine was retrofitted. In 59% of the pharmacies additional space was gained for self-service and behind-the-counter display. As a result of using a robotic dispensing machine, personnel costs were reduced by an average of 4.6% during the first 12 months after start-up. Over-the-counter sales increased in the same period by an average of 6.8%. Despite average initial costs of 118,000 euros, total costs within the first 12 months fell in 50% of cases and at least remained the same in 44%. CONCLUSIONS: On average, robotic dispensing machines lead to modest savings in personnel costs and slight increases in sales of over-the-counter drugs. Substantial savings can be achieved only if the staffing level is adapted to the changed personnel requirements.
