COVID-19 in cancer patients: clinical characteristics and outcome-an analysis of the LEOSS registry.

INTRODUCTION: Since the early SARS-CoV-2 pandemic, cancer patients have been assumed to be at higher risk for severe COVID-19. Here, we present an analysis of cancer patients from the LEOSS (Lean European Open Survey on SARS-CoV-2 Infected Patients) registry to determine whether cancer patients are at higher risk. PATIENTS AND METHODS: We retrospectively analyzed a cohort of 435 cancer patients and 2636 non-cancer patients with confirmed SARS-CoV-2 infection, enrolled between March 16 and August 31, 2020. Data on socio-demographics, comorbidities, cancer-related features and infection course were collected. Age-, sex- and comorbidity-adjusted analysis was performed. Primary endpoint was COVID-19-related mortality. RESULTS: In total, 435 cancer patients were included in our analysis. Commonest age category was 76-85 years (36.5%), and 40.5% were female. Solid tumors were seen in 59% and lymphoma and leukemia in 17.5% and 11% of patients. Of these, 54% had an active malignancy, and 22% had recently received anti-cancer treatments. At detection of SARS-CoV-2, the majority (62.5%) presented with mild symptoms. Progression to severe COVID-19 was seen in 55% and ICU admission in 27.5%. COVID-19-related mortality rate was 22.5%. Male sex, advanced age, and active malignancy were associated with higher death rates. Comparing cancer and non-cancer patients, age distribution and comorbidity differed significantly, as did mortality (14% vs 22.5%, p value < 0.001). After adjustments for other risk factors, mortality was comparable. CONCLUSION: Comparing cancer and non-cancer patients, outcome of COVID-19 was comparable after adjusting for age, sex, and comorbidity. However, our results emphasize that cancer patients as a group are at higher risk due to advanced age and pre-existing conditions.

Treatment outcomes of integrase inhibitors, boosted protease inhibitors and nonnucleoside reverse transcriptase inhibitors in antiretroviral-naïve persons starting treatment.

OBJECTIVES: Although outcomes of antiretroviral therapy (ART) have been evaluated in randomized controlled trials, experiences from subpopulations defined by age, CD4 count or viral load (VL) in heterogeneous real-world settings are limited. METHODS: The study design was an international multicohort collaboration. Logistic regression was used to compare virological and immunological outcomes at 12 ± 3 months after starting ART with an integrase strand transfer inhibitor (INSTI), contemporary nonnucleoside reverse transcriptase inhibitor (NNRTI) or boosted protease inhibitor (PI/b) with two nucleos(t)ides after 1 January 2012. The composite treatment outcome (cTO) defined success as VL < 200 HIV-1 RNA copies/mL with no regimen change and no AIDS/death events. Immunological success was defined as a CD4 count > 750 cells/µL or a 33% increase where the baseline CD4 count was ≥ 500 cells/µL. Poisson regression compared clinical failures (AIDS/death ≥ 14 days after starting ART). Interactions between ART class and age, CD4 count, and VL were determined for each endpoint. RESULTS: Of 5198 ART-naïve persons in the International Cohort Consortium of Infectious Diseases (RESPOND), 45.4% started INSTIs, 26.0% PI/b and 28.7% NNRTIs; 880 (17.4%) were aged > 50 years, 2539 (49.4%) had CD4 counts < 350 cells/µL and 1891 (36.8%) had VL > 100 000 copies/mL. Differences in virological and immunological success and clinical failure among ART classes were similar across age groups (≤ 40, 40-50 and > 50 years), CD4 count categories (≤ 350 vs. > 350 cells/µL) and VL categories at ART initiation (≤ 100 000 vs. > 100 000 copies/mL), with all investigated interactions being nonsignificant (P > 0.05). CONCLUSIONS: Differences among ART classes in virological, immunological and clinical outcomes in ART-naïve participants were consistent irrespective of age, immune suppression or VL at ART initiation. While confounding by indication cannot be excluded, this provides reassuring evidence that such subpopulations will equally benefit from contemporary ART.

Pelvic cellulitis caused by Raoultella planticola in a neutropenic patient.

Raoultella planticola is a gram-negative, encapsulated, aerobic bacterium within the Enterobacteriaceae family. It has been primarily described as pathogen in cases with pneumonia and gastrointestinal infections. Here we describe a case of severe pelvic cellulitis in a patient with neutropenia following induction therapy for myeloid sarcoma. The patient experienced a septic shock and was treated successfully with antibiotic therapy. A literature review is provided to put this case in context with previous reports on R. planticola. This report highlights that awareness for uncommon pathogens is crucial in the clinical management of infections in neutropenic patients.

[Fungal infections]. / Pilzinfektionen.

BACKGROUND: Invasive aspergillosis, mucormycosis, and cryptococcosis are severe opportunistic infections in patients with long phases of neutropenia and also after allogeneic stem cell and organ transplantation. Due to the late appearance of clinical signs and the often poor outcome, these diseases require special attention and proactive interventions. MATERIAL AND METHODS: Published guidelines and selected current literature were reviewed for this article. RESULTS: Invasive aspergillosis and mucormycosis are typically observed in the upper and lower airways of severely immunocompromized patients. When invasive fungal diseases are suspected, sectional imaging and, if possible, serological testing should be performed as soon as possible. If imaging or serological tests confirm the suspected diagnosis, pre-emptive antimycotic treatment should be started and further confirmation of the diagnosis sought via microbiological and/or histological investigations. Treatment depends on comedication, comorbidity and risk factors, primarily with voriconazole, isavuconazole and liposomal amphotericin B. With the advent of antiretroviral treatment, a decrease of cryptococcosis cases in people with human immunodeficiency virus was observed; however, increasing cases have been reported in patients with new forms of immunosuppression. Cryptococcus spp. predominantly cause central nervous system infections but also pneumonia and bloodstream infections. Diagnostics include blood and cerebrospinal fluid cultures and antigen tests. First line treatment consists of a combination therapy with amphotericin B and flucytosine. CONCLUSION: An interdisciplinary approach with microbiologists, infectious diseases specialists and radiologists is needed for diagnostics and treatment of invasive fungal diseases.

Diagnosis and management of gastrointestinal complications in adult cancer patients: 2017 updated evidence-based guidelines of the Infectious Diseases Working Party (AGIHO) of the German Society of Hematology and Medical Oncology (DGHO).

Cancer patients frequently suffer from gastrointestinal complications. In this manuscript, we update our 2013 guideline on the diagnosis and management of gastrointestinal complications in adult cancer patients by the Infectious Diseases Working Party (AGIHO) of the German Society of Hematology and Medical Oncology (DGHO). An expert group was put together by the AGIHO to update the existing guideline. For each sub-topic, a literature search was performed in PubMed, Medline, and Cochrane databases, and strengths of recommendation and the quality of the published evidence for major therapeutic strategies were categorized using the 2015 European Society for Clinical Microbiology and Infectious Diseases (ESCMID) criteria. Final recommendations were approved by the AGIHO plenary conference. Recommendations were made with respect to non-infectious and infectious gastrointestinal complications. Strengths of recommendation and levels of evidence are presented. A multidisciplinary approach to the diagnosis and management of gastrointestinal complications in cancer patients is mandatory. Evidence-based recommendations are provided in this updated guideline.

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.

Serial assessment of pulmonary lesion volume by computed tomography allows survival prediction in invasive pulmonary aspergillosis.

BACKGROUND: Serial chest CT is the standard of care to establish treatment success in invasive pulmonary aspergillosis (IPA). Data are lacking how response should be defined. METHODS: Digital CT images from a clinical trial on treatment of IPA were re-evaluated and compared with available biomarkers. Total volume of pneumonia was added up after manual measurement of each lesion, followed by statistical analysis. RESULTS: One-hundred and ninety CT scans and 309 follow-up datasets from 40 patients were available for analysis. Thirty-one were neutropenic. Baseline galactomannan (OR 4.06, 95%CI: 1.08-15.31) and lesion volume (OR 3.14, 95%CI: 0.73-13.52) were predictive of death. Lesion volume at d7 and trend between d7 and d14 were strong predictors of death (OR 20.01, 95%CI: 1.42-282.00 and OR 15.97, 95%CI: 1.62-157.32) and treatment being rated as unsuccessful (OR 4.75, 95%CI: 0.94-24.05 and OR 40.69, 95%CI: 2.55-649.03), which was confirmed by a Cox proportional hazards model using time-dependent covariates. CONCLUSION: Any increase in CT lesion volume between day 7 and day 14 was a sensitive marker of a lethal outcome (>50%), supporting a CT rescan each one and 2 weeks after initial detection of IPA. The predictive value exceeded all other biomarkers. Further CT follow-up after response at day 14 was of low additional value. KEY POINTS: • CT evaluation offers good prediction of outcome for invasive pulmonary aspergillosis. • Predictive capability exceeds galactomannan, blood counts, and lesion count. • Any progression between day 7 and day 14 constitutes a high-risk scenario.

Measles, mumps, rubella and VZV: importance of serological testing of vaccine-preventable diseases in young adults living with HIV in Germany.

Measles, mumps, rubella (MMR) and varicella zoster virus (VZV) infection can cause serious diseases and complications in the HIV-positive population. Due to successful vaccination programmes measles, mumps and congenital rubella syndrome has become neglected in Germany. However, recent outbreaks of measles have occurred from import-associated cases. In this cross-sectional study the serostatus for MMR and VZV in 2013 HIV-positive adults from three different university outpatient clinics in Bonn (n = 544), Cologne (n = 995) and Munich (n = 474) was analysed. Sera were tested for MMR- and VZV-specific immunglobulin G antibodies using commercial immunoassays. Seronegativity was found in 3% for measles, 26% for mumps, 11% for rubella and 2% for VZV. Regarding MMR, 35% of patients lacked seropositivity against at least one infectious agent. In multivariable analysis younger age was strongly associated with seronegativity against all four viruses, measles, mumps, rubella (P < 0·001, P < 0·001 and P = 0·001, respectively) and VZV (P = 0·001). In conclusion, there is high need for MMR and VZV vaccination in people living with HIV in Germany born in 1970 or later. Thus, systematic MMR and VZV antibody screening and vaccination should be implemented in the HIV-positive population to prevent serious disease and complications of vaccine-preventable diseases.

Domestic mould exposure and invasive aspergillosis-air sampling of Aspergillus spp. spores in homes of hematological patients, a pilot study.

UNLABELLED: Aspergillus spp.-related morbidity and mortality remains a major challenge in the management of neutropenic patients. Little is known about the impact of domestic Aspergillus spp. EXPOSURE: In this controlled prospective study, fungal spores were collected from homes of neutropenic patients. Cases were defined as patients with probable or proven controls as patients with no invasive pulmonary aspergillosis, while patients with possible disease were evaluated as a third group. Forty patients were enrolled and returned questionnaires on high-risk activities and mould exposure. A. fumigatus was detected in concentrations of 0 to 76 cfu/m(3) in every home. A. terreus was detected in nine (18%) homes. Mean Aspergillus spp. cfu/m(3) according to EORTC criteria were: proven/probable IA (15 patients) - 36; possible IA (12 patients) - 42; no IA (13 patients) - 42. Of the seven patients with self-reported moulded walls at home, four had probable and three had possible aspergillosis; the risk ratio of developing IA was 1.65 (95% CI: 1.25-2.17). In conclusion self-reported domestic mould exposure was associated with a high incidence of IA and may be a feasible tool for identifying high-risk patients. There was no correlation between domestic ambient-air spore counts and IA.

Candidemia in the intensive care unit: analysis of direct treatment costs and clinical outcome in patients treated with echinocandins or fluconazole.

Direct treatment costs caused by candidemia in German intensive care unit (ICU) patients are currently unknown. We analyzed treatment costs and the impact of antifungal drug choice. Comprehensive data of patients who had at least one episode of candidemia while staying in the ICU between 01/2005 and 12/2010 were documented in a database using the technology of the Cologne Cohort of Neutropenic Patients (CoCoNut). A detailed analysis of all disease-associated treatment costs was performed. Patients treated with echinocandins (i.e., anidulafungin, caspofungin, micafungin) or fluconazole were analyzed separately and compared. Forty-one and 64 patients received echinocandins and fluconazole, respectively. The mean Acute Physiology and Chronic Health Evaluation (APACHE) IV score was 114 (95 % confidence interval [CI]: 106-122) vs. 95 (95 % CI: 90-101, p = <0.001). Twenty-three (56 %) and 33 (52 %, p = 0.448) patients survived hospitalization, while 17 (41 %) and 22 (34 %, p = 0.574) survived one year after diagnosis. In the echinocandin and fluconazole groups, the mean costs per patient of ICU treatment were 20,338 (95 % CI: 12,893-27,883) vs. 11,932 (95 % CI: 8,016-15,849, p = 0.110), and the total direct treatment costs per patient were 37,995 (95 % CI: 26,614-49,376) vs. 22,305 (95 % CI: 16,817-27,793, p = 0.012), resulting in daily costs per patient of 1,158 (95 % CI: 1,036-1,280) vs. 927 (95 % CI: 828-1,026, p = 0.001). Our health economic analysis shows the high treatment costs of patients with candidemia in the ICU. Sicker patients had a prolonged hospitalization and were more likely to receive echinocandins, leading to higher treatment costs. Outcomes were comparable to those achieved in less sick patients with fluconazole.

Economic burden of Clostridium difficile associated diarrhoea: a cost-of-illness study from a German tertiary care hospital.

PURPOSE: Clostridium difficile associated diarrhoea (CDAD) is the most common cause of health-care-associated infectious diarrhoea. In the context of the German health-care system, direct and indirect costs of an initial episode of CDAD and of CDAD recurrence are currently unknown. METHODS: We defined CDAD as presence of diarrhoea (≥3 unformed stools/day) in association with detection of Clostridium difficile toxin in an unformed faecal sample. Patients treated with metronidazole (PO or IV) and/or vancomycin (PO) were included. Comprehensive data of patients were retrospectively documented into a database using the technology of the Cologne Cohort of Neutropenic Patients (CoCoNut). Patients with CDAD were matched to control patients in a 1:1 ratio. Analysis was split in three groups: incidence group (CDAD patients without recurrence), recurrence group (CDAD patients with ≥1 recurrence) and control group (matched non-CDAD patients). RESULTS: Between 02/2010 and 12/2011, 150 patients with CDAD (114 patients in the incidence and 36 (24 %) in the recurrence group) and 150 controls were analysed. Mean length of stay was: 32 (95 %CI: 30-37), 94 (95 %CI: 76-112) and 24 days (95 %CI: 22-27; P = <0.001), resulting in mean overall direct treatment costs per patient of €18,460 (95 %CI: €14,660-€22,270), €73,900 (95 %CI: €50,340-€97,460) and €14,530 (95 %CI: €11,730-€17,330; P = <0.001). In the incidence and recurrence group, the mean cumulative number of antibiotic CDAD treatment days was 11 (95 %CI: 10-12) and 36 (95 %CI: 27-45; P = <0.001). CONCLUSIONS: Especially CDAD recurrence was associated with excessive costs, which were mostly attributable to a significantly longer overall length of stay. Innovative treatment strategies are warranted to reduce treatment costs and prevent recurrence of CDAD.

Our 2015 approach to invasive pulmonary aspergillosis.

At the University Hospital of Cologne, in general two patient groups at high risk for invasive aspergillosis receive posaconazole prophylaxis: Acute myelogenous leukaemia patients during remission induction chemotherapy and allogeneic haematopoietic stem cell transplant recipients. Other patients at risk undergo serum galactomannan testing three times weekly. At 72-96 h of persisting fever despite broad-spectrum antibiotics, or at onset of lower respiratory tract symptoms a thoracic computed tomography (CT) scan is performed. Without lung infiltrates on CT, IPA is ruled out. In lung infiltrates not suggestive for IPA mycological confirmation is pursued. In patients without posaconazole prophylaxis empiric caspofungin will be considered. CT findings typical for IPA prompt targeted treatment, and mycological confirmation. Bronchoalveolar lavage (BAL) is most important for cultural identification and susceptibility testing, and facilitates diagnosing other pathogens. BAL performance is virtually independent of platelet counts. If despite suggestive infiltrates BAL does not yield the diagnosis, CT-guided biopsy follows as soon as platelet counts allow. Surgery can also be beneficial in diagnosis and treatment of IPA. If the diagnosis of IPA is not established, mucormycosis is a valid concern. In patients with breakthrough IPA during posaconazole prophylaxis liposomal amphotericin B is the drug of choice. If no posaconazole prophylaxis was given, voriconazole is the treatment of choice for IPA.

Identification of invasive fungal diseases in immunocompromised patients by combining an Aspergillus specific PCR with a multifungal DNA-microarray from primary clinical samples.

The increasing incidence of invasive fungal diseases (IFD), most of all invasive aspergillosis (IA) in immunocompromised patients emphasises the need to improve the diagnostic tools for detection of fungal pathogens. We investigated the diagnostic performance of a multifungal DNA-microarray detecting 15 different fungi [Aspergillus, Candida, Fusarium, Mucor, Rhizopus, Scedosporium and Trichosporon species (spp.)] in addition to an Aspergillus specific polymerase chain reaction (PCR) assay. Biopsies, bronchoalveolar lavage and peripheral blood samples of 133 immunocompromised patients (pts) were investigated by a multifungal DNA-microarray as well as a nested Aspergillus specific PCR assay. Patients had proven (n = 18), probable (n = 29), possible (n = 48) and no IFD (n = 38) and were mostly under antifungal therapy at the time of sampling. The results were compared to culture, histopathology, imaging and serology, respectively. For the non-Aspergillus IFD the microarray analysis yielded in all samples a sensitivity of 64% and a specificity of 80%. Best results for the detection of all IFD were achieved by combining DNA-microarray and Aspergillus specific PCR in biopsy samples (sensitivity 79%; specificity 71%). The molecular assays in combination identify genomic DNA of fungal pathogens and may improve identification of causative pathogens of IFD and help overcoming the diagnostic uncertainty of culture and/or histopathology findings, even during antifungal therapy.

Prophylaxis of infectious complications with colony-stimulating factors in adult cancer patients undergoing chemotherapy-evidence-based guidelines from the Infectious Diseases Working Party AGIHO of the German Society for Haematology and Medical Oncology (DGHO).

BACKGROUND: Current evidence on myelopoietic growth factors is difficult to overview for the practicing haematologist/oncologist. International guidelines are sometimes conflicting, exclude certain patient groups, or cannot directly be applied to the German health system. This guideline by the Infectious Diseases Working Party (AGIHO) of the German Society of Haematology and Medical Oncology (DGHO) gives evidence-based recommendations for the use of G-CSF, pegylated G-CSF, and biosimilars to prevent infectious complications in cancer patients undergoing chemotherapy, including those with haematological malignancies. METHODS: We systematically searched and evaluated current evidence. An expert panel discussed the results and recommendations. We then compared our recommendations to current international guidelines. RESULTS: We summarised the data from eligible studies in evidence tables, developed recommendations for different entities and risk groups. CONCLUSION: Comprehensive literature search and expert panel consensus confirmed many key recommendations given by international guidelines. Evidence for growth factors during acute myeloid leukaemia induction chemotherapy and pegfilgrastim use in haematological malignancies was rated lower compared with other guidelines.

Causes of death in HIV-infected patients from the Cologne-Bonn cohort.

PURPOSE: Causes of death in human immunodeficiency virus (HIV)-infected subjects have changed in countries with high resources over the last several years. Acquired immunodeficiency syndrome (AIDS)-related diseases have become less prevalent, whereas deaths due to non-AIDS causes are increasing. The aim of the present study was to analyse causes of death in the Cologne-Bonn cohort. METHODS: Causes of death from the Cologne-Bonn cohort between 2004 and 2010 were systematically recorded using the CoDe algorithm (The Coding Causes of Death in HIV Project). RESULTS: In 3,165 patients followed from 2004 to 2010, 182 deaths occurred (5.7 %, 153 males, 29 females). The median age at the time of death was 47 years (range 24-85 years). The most frequent causes of death were AIDS-defining events (n = 60, 33 %), with non-Hodgkin lymphoma (NHL) (n = 29, 16 %) and infections (n = 20, 11 %) being the leading entities in this category. Non-AIDS malignancies accounted for 16 % (n = 29), non-HIV-related infections for 10 % (n = 18), cardiovascular diseases for 7 % (n = 14), suicide or accident for 4 % (n = 7) and liver diseases for 3 % (n = 5) of deaths (unknown n = 47, 26 %). Although the majority of patients (92.5 %) was on antiretroviral therapy (ART), only 50 % were virologically suppressed (HIV-RNA <50 copies/mL) and 44 % had a decreased CD4+ count (<200/µL) at their last visit before death. CONCLUSION: One-third of the causes of death in our cohort between 2004 and 2010 was AIDS-related. Since most of these deaths occur with severe immune suppression, they can possibly be prevented by the early diagnosis and treatment of HIV infection. Care providers must be aware of an increased risk for a broad range of diseases in HIV-infected patients and should apply appropriate preventive measures.

Clinical course and quality of care in ART-naïve patients newly presenting in a HIV outpatient clinic.

OBJECTIVES: Little data exist about the quality of care for HIV-infected subjects in Germany. We investigated the clinical course of HIV-infected subjects newly presenting in our HIV outpatient clinic. METHODS: Antiretroviral therapy (ART)-naïve HIV-infected subjects presenting between 2007 and 2008 were followed until June 2012. Clinical data and laboratory parameters were collected prospectively and analysed retrospectively. RESULTS: From 281 subjects included, 34 patients (12%) were lost to follow-up. 247 subjects remained, and 171 patients were followed for 1,497 days [1,121/1,726] (all data: median [interquartile range]). ART was started in 199 patients (81%) 182 days [44/849] after HIV diagnosis, and all patients were treated according to European guidelines or within clinical trials. The CD4 cell count at first presentation was 320/µL [160/500] and declined to 210/µL [100/300] at ART start. 12 months thereafter, the CD4 cell count increased to 410/µL [230/545]. The HIV RNA was suppressed below 50 copies/mL after 108 days [63/173] in 182 patients (91%). Initial ART was changed in 71 patients (36%) after 281 days [99/718], in five patients (7%) due to virological failure, in 66 patients (93%) due to other reasons, e.g. side effects or patient's request. CONCLUSION: Two-thirds of the included patients were followed for more than 3 years, and ART was initiated in 81% of the patients leading to complete virological suppression in most patients. Compliance of physicians with treatment guidelines was high. Late presentation with a severely compromised immune function remains a problem and impairs the otherwise good prognosis of HIV infection.

Different doses of micafungin for prophylaxis of invasive fungal diseases in hemato-oncological high-risk patients: a web-based non-interventional trial in four large university hospitals in Germany.

INTRODUCTION: Treatment indications of new antifungals in clinical practice often deviate from the strict criteria used in controlled clinical trials. Under routine clinical conditions, beneficial and adverse effects, not previously described in clinical trials may be observed. The aim of this study was to describe customary prescription and treatment strategies of micafungin (MCFG). METHODS: A registry was set up on www.ClinicalSurveys.net and physicians were invited to provide retrospective information on cases they had treated with MCFG. Documentation comprised demographic information, underlying disease, effectiveness, safety, and tolerability of MCFG. RESULTS: A total of 125 episodes of patients hospitalized between September 2009 and February 2012 were documented, of which 7 had to be excluded because of incomplete documentation. The most common risk factors of patients were hematological malignancy (n = 116, 98.3%) and antibiotic treatment >3 days (n = 115, 97.5%). MCFG was administered as prophylaxis in 106 (89.9%) patients. Median duration of MCFG application as prophylaxis was 21 days (range: 3-78); 53 of the patients (50%) received a dose of 50 mg, while the other 53 (50%) received 100 mg/day. For the different doses, prophylactic outcome was rated as success in 42 (79.2%) vs. 52 (98.1%; P = 0.004) patients. Fifty-five patients (51.9%) were treated with posaconazole before initiation of MCFG. Four patients (7.5%) developed a proven invasive fungal disease (IFD) while being treated with 50 mg MCFG, compared to no patient treated with 100 mg (P = 0.118). At the end of MCFG prophylaxis, 24 (22.6%) patients were switched to fluconazole and 64 (60.3%) patients to posaconazole. CONCLUSION: Our study shows clinical effectiveness of MCFG prophylaxis with low rates of breakthrough fungal infections. In most cases, MCFG was part of a multi-modal antifungal prophylactic strategy. Investigators reported fewer proven IFDs in patients receiving therapeutic doses of MCFG as prophylaxis.

Costs and resource utilization patterns in surgical site infections: a pre-COVID-19 perspective from France, Germany, Spain, and the UK.

BACKGROUND: Surgical site infections (SSIs), mainly caused by Staphylococcus aureus, pose a significant economic burden in Europe, leading to increased hospitalization duration, mortality, and treatment costs, particularly with drug-resistant strains such as meticillin-resistant S. aureus. AIM: To conduct a case-control study on the economic impact of S. aureus SSI in adult surgical patients across high-volume centres in France, Germany, Spain, and the UK, aiming to assess the overall and procedure-specific burden across Europe. METHODS: The SALT study is a multinational, retrospective cohort study with a nested case-control analysis focused on S. aureus SSI in Europe. The study included participants from France, Germany, Italy, Spain, and the UK who underwent invasive surgery in 2016 and employed a micro-costing approach to evaluate health economic factors, matching S. aureus SSI cases with controls. FINDINGS: In 2016, among 178,904 surgical patients in five European countries, 764 developed S. aureus SSI. Matching 744 cases to controls, the study revealed that S. aureus SSI cases incurred higher immediate hospitalization costs (€8,810), compared to controls (€6,032). Additionally, S. aureus SSI cases exhibited increased costs for readmissions within the first year post surgery (€7,961.6 versus €5,298.6), with significant differences observed. Factors associated with increased surgery-related costs included the cost of hospitalization immediately after surgery, first intensive care unit (ICU) admission within 12 months, and hospital readmission within 12 months, as identified through multivariable analysis. CONCLUSION: The higher rates of hospitalization, ICU admissions, and readmissions among S. aureus SSI cases highlight the severity of these infections and their impact on healthcare costs, emphasizing the potential benefits of evidence-based infection control measures and improved patient care to mitigate the economic burden.

Diagnosis and management of gastrointestinal complications in adult cancer patients: evidence-based guidelines of the Infectious Diseases Working Party (AGIHO) of the German Society of Hematology and Oncology (DGHO).

BACKGROUND: Cancer patients frequently suffer from gastrointestinal complications. However, a comprehensive, practical and evidence-based guideline on this issue is not yet available. PATIENTS AND METHODS: An expert group was put together by the Infectious Diseases Working Party (AGIHO) of the German Society of Hematology and Oncology (DGHO) to develop a guideline on gastrointestinal complications in cancer patients. For each subtopic, a literature search was carried out in PubMed, Medline and Cochrane databases and the strength of recommendation and the quality of the published evidence for major therapeutic strategies were categorized using a modification of the 'Infectious Diseases Society of America' criteria. Consensus discussions were held on each of the topics. RESULTS: Recommendations were made with respect to non-infectious and infectious gastrointestinal complications. For all recommendations, the strength of the recommendation and the level of evidence are presented. CONCLUSION: This guideline is an evidence-based approach to the diagnosis and management of gastrointestinal complications in cancer patients.

Evaluation of an infectious disease consultation programme in a German tertiary care hospital.

PURPOSE: To evaluate a newly implemented infectious disease (ID) consultation service in terms of patient care, outcome and antibiotic prescription and to describe factors influencing adherence to recommendations. METHODS: Data from consultations during the first 6 months of the ID consultation program were collected and evaluated. Consultation requests, diagnostic results, treatment outcomes and antibiotic recommendations were categorised. Diagnostic and therapeutic recommendations were assessed and rated for adherence and outcome. Statistical analysis was performed to identify factors influencing adherence and treatment outcome. RESULTS: A total of 251 consultations were assessed. In most cases, ID specialists were asked for further advice regarding a previously initiated anti-infective treatment (N = 131, 52 %). In 54 of 195 (28 %) first consultations, the ID specialist proposed a differential diagnosis that differed from that of the working diagnoses submitted with the consultation request, and which was subsequently confirmed in 80 % of these cases. Diagnostic and therapeutic recommendations were made in 190 (76 %) and 240 (96 %) of the consultations, respectively. A change in the current treatment was recommended in 66 % of consultations; 37 % of recommendations were cost-saving and 26 % were cost-neutral. Compliance with diagnostic and therapeutic recommendations was rated as good by pre-specified criteria in 65 and 86 % of consultations, respectively. Treatment outcome was correlated with adherence to diagnostic recommendations (P = 0.012). Twenty-nine patients (16 %) died during the same hospital stay. CONCLUSION: Infectious disease consultations may help to establish the correct diagnosis, resulting in the appropriate treatment being provided to a severely sick patient population. Treatment outcome was improved in cases of good diagnostic adherence to the recommendations of the ID specialist.
