RESUMO
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.

BACKGROUND: Pneumocystis jirovecii pneumonia (PCP) incidence is increasing in patients without HIV infection. In contrast to PCP in patients infected with HIV, diagnosis is often delayed and illness is associated with increased mortality. OBJECTIVES: To provide a comprehensive review of clinical presentation, risk factors, diagnostic strategies, and treatment options for PCP in patients without HIV infection. SOURCES: Web-based literature review on PCP for trials, meta-analyses, and systematic reviews using PubMed. The restriction to the English language was applied. CONTENT: Common underlying conditions in patients without HIV infection having PCP are haematological malignancies, autoimmune and inflammatory diseases, solid organ or haematopoietic stem cell transplant, and previous corticosteroid exposure. New risk groups include patients receiving monoclonal antibodies and immunomodulating therapies. Patients without HIV infection who have PCP present with rapid onset and progression of pneumonia, increased duration of hospitalization and a significantly higher mortality rate than patients infected with HIV. PCP is diagnosed by a combination of clinical symptoms and radiological as well as mycological features. Results of immunofluorescence microscopy from bronchoalveolar lavage, PCR testing, and computed tomography imaging as well as the evaluation of clinical presentation are required. The established treatment regime consists of trimethoprim and sulfamethoxazole. IMPLICATIONS: Although the number of patients with immunosuppression due to causes different from HIV is increasing, a simultaneous rise in PCP incidence is observed. In the group of patients without HIV infection, rapid onset of symptoms, a more complex course, and a high mortality rate are recorded. Therefore, the time to diagnosis must be as short as possible to initiate effective therapy promptly. This review aims to raise awareness of PCP in an increasingly affected at-risk group and provides clinicians with a practical guide for efficient diagnosis and targeted therapy. Furthermore, it intends to display current inadequacies in research on the topic of PCP.

Advances in medicine have led to a growing number of people with compromised or suppressed immune systems who are susceptible to invasive fungal infections. In particular, severe fungal infections are becoming increasingly common in ICUs, affecting people within and outside of traditional risk groups alike. This is exemplified by the emergence of severe viral pneumonia as a significant risk factor for invasive pulmonary aspergillosis, and the recognition of influenza-associated pulmonary aspergillosis and, more recently, COVID-19-associated pulmonary aspergillosis. The treatment landscape for haematological malignancies has changed considerably in recent years, and some recently introduced targeted agents, such as ibrutinib, are increasing the risk of invasive fungal infections. Consideration must also be given to the risk of drug-drug interactions between mould-active azoles and small-molecule kinase inhibitors. At the same time, infections caused by rare moulds and yeasts are increasing, and diagnosis continues to be challenging. There is growing concern about azole resistance among both moulds and yeasts, mandating continuous surveillance and personalized treatment strategies. It is anticipated that the epidemiology of fungal infections will continue to change and that new populations will be at risk. Early diagnosis and appropriate treatment remain the most important predictors of survival, and broad-spectrum antifungal agents will become increasingly important. Liposomal amphotericin B will remain an essential therapeutic agent in the armamentarium needed to manage future challenges, given its broad antifungal spectrum, low level of acquired resistance and limited potential for drug-drug interactions.

OBJECTIVES: Lomentospora prolificans is an emerging cause of serious invasive fungal infections. Optimal treatment of these infections is unknown, although voriconazole-containing treatment regimens are considered the treatment of choice. The objective of this study was to evaluate the role of combination antifungal therapy for L. prolificans infections. METHODS: We performed a retrospective review of medical records of patients with invasive L. prolificans infection diagnosed between 1 January 2008 and 9 September 2019 that were documented in the FungiScope® registry of rare invasive fungal infections. We compared clinical outcomes between antifungal treatment strategies. RESULTS: Over the study period, 41 individuals with invasive L. prolificans infection from eight different countries were documented in the FungiScope® registry. Overall, 17/40 (43%) had treatment response/stable disease and 21/40 (53%) had a fatal outcome attributed to invasive fungal infection. Combination antifungal therapy was associated with increased 28-day survival (15/24 survived versus 4/16 receiving monotherapy; p 0.027) and the combination voriconazole plus terbinafine trended to be associated with higher rates of treatment success (10/16, 63%, 95% CI 35%-85%) compared with other antifungal treatment regimens (7/24, 29%, 95% CI 13%-51%, p 0.053). In Kaplan-Meier survival analysis there was a higher survival probability in individuals receiving the voriconazole/terbinafine combination compared with other antifungal regimens (median survival 150 days versus 17 days). CONCLUSIONS: While overall mortality was high, combination antifungal treatment, and in particular combination therapy with voriconazole plus terbinafine may be associated with improved treatment outcomes compared with other antifungal regimens for the treatment of invasive L. prolificans infections.

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.

OBJECTIVES: Candidaemia is a serious hazard to hospitalized patients, but European epidemiological data are restricted to national studies focusing on Northern Europe, population-based surveillance programmes or studies conducted in distinct local areas. The aim was to provide current data on the overall burden and epidemiological development of candidaemia in Europe. METHODS: A Web of Knowledge™ search was carried out from January 2000 to February 2019. Appropriate data were collected on total cases, study duration, incidence, species distribution and/or mortality rates. Meta-analysis was performed to pool individual studies. Heterogeneity was examined using the I2 statistic. Calculations of pooled incidence and mortality rates, subgroup analysis by geographical origin, study period and scenarios were carried out. Daily candidaemia incidence and mortality rates in Europe were extrapolated. Systematic review and meta-analysis were used to determine incidence and mortality of candidaemia in the UN European region. Complete datasets were categorized into population-based and hospital-based epidemiological studies and were analysed separately. Subgroup analyses were performed for geographic distributions and time-dependent developments. RESULTS: In population-based studies, 43 799 cases of candidaemia were diagnosed in 1 885 271 885 person-years, revealing an overall pooled incidence rate of 3.88/100 000. The highest pooled incidence rate was observed in intensive care units (5.5/1000 admissions, Day 30 mortality rate 37%), followed by tertiary care centres (0.96/1000 admissions, pooled Day 30 mortality rate 38%) and the mixed group of teaching and general hospitals (0.52/1000 admissions, pooled Day 30 mortality rate 37%). European incidence of candidaemia was extrapolated to approximately 79 cases per day, of which an estimated 29 patients might have fatal outcome at Day 30. CONCLUSIONS: Pooled incidence rates, species distribution and outcome of candidaemia differ considerably between clinical groups, European regions and over time. We observed an increasing overall pooled incidence rate of candidaemia and a higher proportion of Candida spp. other than C. albicans in the current decade in population-based data.

BACKGROUND: Severe pulmonary infections are among the most common reasons for admission to intensive care units (ICU). Within the last decade, increasing reports of severe influenza pneumonia resulting in acute respiratory distress syndrome (ARDS) complicated by Aspergillus infection were published. OBJECTIVES: To provide a comprehensive review of management of influenza-associated pulmonary aspergillosis in patients with ARDS. SOURCES: Review of the literature pertaining to severe influenza-associated pulmonary aspergillosis. PubMed database was searched for publications from the database inception to January 2019. CONTENT: In patients with lower respiratory symptoms, development of respiratory insufficiency should trigger rapid and thorough clinical evaluation, in particular in cases of suspected ARDS, including electrocardiography and echocardiography to exclude cardiac dysfunction, arrhythmias and ischaemia. Bronchoalveolar lavage should obtain lower respiratory tract samples for galactomannan assay, direct microscopy, culture, and bacterial, fungal and viral PCR. In case of positive Aspergillus testing, chest CT is the imaging modality of choice. If influenza pneumonia is diagnosed, neuraminidase inhibitors are the preferred approved drugs. When invasive aspergillosis is confirmed, first-line therapy consists of isavuconazole or voriconazole. Isavuconazole is an alternative in case of intolerance to voriconazole, drug-drug interactions, renal impairment, or if a spectrum of activity including the majority of Mucorales is desired. Primary anti-mould prophylaxis with posaconazole is recommended in haematology patients at high-risk. It may be considered in newly diagnosed influenza and ARDS, but ideally in clinical trials. IMPLICATIONS: The rising reports of influenza-associated pulmonary aspergillosis in patients with ARDS, who are otherwise not considered at risk for fungal pneumonia demands heightened clinical awareness. Tracheobronchitis and Aspergillus in respiratory tract samples should prompt suspicion of invasive fungal infection and further work-up. The management algorithm should comprise bronchoalveolar lavage, CT imaging, sophisticated ventilator-management, rescue extracorporeal membrane oxygenation, and antifungal and antiviral therapy. To decrease the burden of influenza-related illness, vaccination is of utmost importance, specifically in patients with co-morbidities.

Establishing the etiology of invasive fungal infections is important to guide therapeutic options and for epidemiologic purposes. Formalin-fixed, paraffin-embedded (FFPE) tissue specimens from patients with proven invasive fungal infections are valuable to determine the etiology of systemic fungal infections. We compared different polymerase chain reaction (PCR) amplification strategies from FFPE tissue blocks to identify agents of invasive fungal infections. We found that specific PCR assays show superior sensitivity in the identification of DNA of Mucorales and Aspergillus and mixed infections caused by both as compared to broad-range PCR assays. Shorter amplicon lengths and less detection of contaminating fungal DNA are potential factors involved. However, detection of fungal DNA by highly sensitive specific PCR assays in the absence of demonstration of fungal elements in tissue suggests that PCR results should be interpreted in the context of the histopathology and clinical findings.

BACKGROUND: Invasive mucormycosis (IM) is a rare invasive fungal infection with a high mortality rate. However, data concerning the clinical and economic burden of IM are scarce. AIM: To evaluate the direct treatment costs and additional expenditures of patients with IM. METHODS: A retrospective cost-of-illness analysis of cases with IM extracted from FungiScope - Global Registry for Emerging Fungal Infections, accessible through the epidemiological research platform www.ClinicalSurveys.net, was undertaken. Results of patients with IM were compared with those of matched patients with similar underlying conditions based on the German Diagnosis Related Group (G-DRG) coding. FINDINGS: Out of 46 patients with probable/proven IM, 31 (67%) patients were male and the median age was 53 years (range 11-88 years). Forty-two patients (92%) had haematological diseases as the most common risk factor. Analysis of cost factors identified antifungal treatment due to IM as the primary cost driver [22,816, 95% confidence interval (CI) 15,036-32,346], with mean overall direct treatment costs of 53,261 (95% CI 39,660-68,825). Compared with matched patients, patients with IM were treated in hospital for 26.5 additional days (standard deviation 31.8 days; P < 0.001), resulting in mean additional costs of 32,991 (95% CI 21,558-46,613; P < 0.001). Probable IM, as well as absence of chemotherapy, surgical measures due to IM, and antifungal prophylaxis were associated with lower overall costs. Nineteen patients (41.3%) died during hospitalization. CONCLUSION: This study demonstrates the considerable healthcare burden of IM. The choice of antifungal agent for treatment of IM had no impact on overall cost.

INTRODUCTION: Cryptococcosis in immunocompetent adults is a rare disease in Europe, mostly induced by members of the Cryptococcus gattii species complex. The diagnosis can be challenging due to its rarity, unspecific symptoms and long symptomless latency. CASE PRESENTATION: A 49-year-old woman with a three weeks history of headache was admitted to the hospital due to discrete ataxia and impaired vision. Cranial magnetic resonance imaging (MRI) showed a contrast-enhancing mass in the cerebellum. Further investigations detected a slight leukocytosis and a single subpleural nodule in the right inferior lung lobe. The cerebral lesion was surgically removed, and a direct frozen section only showed an unspecific inflammation. In the course of her admission she developed non-treatable cerebral edema and died ten days after surgical intervention. Histopathological examination of the surgical specimen and postmortem evaluation of the lung and the cerebrum demonstrated fungal elements. Molecular identification of the fungal elements in formalin-fixed paraffin-embedded tissue lead to the diagnosis of cryptococcosis induced by C. gattii sensu lato. Molecular genetic analysis identified the involved cryptococcal species as genotype AFLP6/VGII, recently described as Cryptococcus deuterogattii, which is known to be endemic to the west-coast of Canada and the USA. Additional heteroanamnestic information revealed that she had spent her holidays on Vancouver Island, Canada, two years before disease onset, indicating that infection during this stay seems to be plausible. CONCLUSION: Cryptococcosis due to C. deuterogattii is a rarely encountered fungal disease in Europe, not particularly associated with immunodeficiency, and infection is likely to be contracted in endemic areas. Due to its rarity, long symptomless latency, unspecific symptoms and misleading radiological features the diagnosis can be challenging. Physicians need to be aware of this differential diagnosis in immunocompetent patients, as early adequate therapy can be lifesaving.
RESUMO
AIMS: Due to the increase of severely immunocompromised patients, of invasive procedures including central intravascular catheters, and of the use of broad-spectrum antibiotics, the incidence of Candida bloodstream infections has risen intensely in the last decades. Candida bloodstream infection is a serious disease with high mortality. Optimized diagnostic and therapeutic management can improve outcome. Thus, the aim of our mini-review is to highlight important and often missed opportunities in the management of Candida bloodstream infection. METHODS: We searched the published literature and describe the essentials in the management of Candida bloodstream infection. RESULTS: Four essentials were identified: (1) isolation of Candida spp. from a blood culture should always be considered relevant and requires treatment. Daily blood cultures should be drawn to determine cessation of candidemia. (2) Central venous catheter (CVC) and/or other indwelling devices should be removed. (3) Echinocandins are the first choice. Antifungal treatment should be continued for at least 14 days after cessation of fungemia. Susceptibility testing should be performed to identify resistance and to facilitate transition to oral treatment. (4) In persistent candidemia, echocardiography is an important investigation; ophthalmoscopy should be considered. CONCLUSION: Further efforts should be undertaken to increase the adherence to the essentials in the management of Candia bloodstream infection.

Infectious complications are a significant cause of morbidity and mortality in patients with malignancies specifically when receiving anticancer treatments. Prevention of infection through vaccines is an important aspect of clinical care of cancer patients. Immunocompromising effects of the underlying disease as well as of antineoplastic therapies need to be considered when devising vaccination strategies. This guideline provides clinical recommendations on vaccine use in cancer patients including autologous stem cell transplant recipients, while allogeneic stem cell transplantation is subject of a separate guideline. The document was prepared by the Infectious Diseases Working Party (AGIHO) of the German Society for Hematology and Medical Oncology (DGHO) by reviewing currently available data and applying evidence-based medicine criteria.

Recent data link the incidence of intestinal GvHD (iGvHD) after allogeneic haematopoietic stem cell transplantation (aSCT) to exposure with piperacillin-tazobactam or imipenem-cilastatin. To assess relevance of timing, duration, sequence and combination of antibiotic treatment in this setting, we applied a time-dependent model to our aSCT cohort. Patients from the prospective Cologne Cohort of Neutropenic Patients (CoCoNut) undergoing aSCT from January 2007 to April 2013 were included into a time-dependent multivariate Cox proportional hazards regression model with backward-stepwise selection. In 399 eligible patients, cumulative antibiotic exposure (hazard ratio (HR) 2.46; 95% confidence interval (95% CI) 1.59-3.81; P<0.001) and exposure to sequential treatment with penicillin derivatives and carbapenems (HR 6.22, 95% CI 1.27-30.31), but not to the individual classes, were associated with iGvHD at day 100. Glycopeptides were assessed as a risk factor (HR 3.73, 95% CI 1.51-9.19), but not considered independent, since their use was dependent on previous exposure to penicillin derivatives and carbapenems. Patients with iGvHD presented with increased non-relapse mortality at day 365 (HR 3.51; 95% CI 2.10-5.89; P<0.001). We identified sequential exposure to penicillin derivatives and carbapenems as well as overall exposure to antibiotics as independent risk factors for iGVHD. Confirmation of these findings in larger, prospective cohorts is necessary.

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.

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.

OBJECTIVES: A prospective international multicentre surveillance study was conducted to investigate the prevalence and amphotericin B susceptibility of Aspergillus terreus species complex infections. METHODS: A total of 370 cases from 21 countries were evaluated. RESULTS: The overall prevalence of A. terreus species complex among the investigated patients with mould-positive cultures was 5.2% (370/7116). Amphotericin B MICs ranged from 0.125 to 32 mg/L, (median 8 mg/L). CONCLUSIONS: Aspergillus terreus species complex infections cause a wide spectrum of aspergillosis and the majority of cryptic species display high amphotericin B MICs.

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.
