Efficacy and safety of an early oral switch in low-risk Staphylococcus aureus bloodstream infection (SABATO): an international, open-label, parallel-group, randomised, controlled, non-inferiority trial. THE LANCET. INFECTIOUS DISEASES 2024; 24:523-534. [PMID: 38244557 DOI: 10.1016/s1473-3099(23)00756-9] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/03/2023] [Revised: 11/30/2023] [Accepted: 12/01/2023] [Indexed: 01/22/2024]
Abstract
BACKGROUND Staphylococcus aureus bloodstream infection is treated with at least 14 days of intravenous antimicrobials. We assessed the efficacy and safety of an early switch to oral therapy in patients at low risk for complications related to S aureus bloodstream infection. METHODS In this international, open-label, randomised, controlled, non-inferiority trial done in 31 tertiary care hospitals in Germany, France, the Netherlands, and Spain, adult patients with low-risk S aureus bloodstream infection were randomly assigned after 5-7 days of intravenous antimicrobial therapy to oral antimicrobial therapy or to continue intravenous standard therapy. Randomisation was done via a central web-based system, using permuted blocks of varying length, and stratified by study centre. The main exclusion criteria were signs and symptoms of complicated S aureus bloodstream infection, non-removable foreign devices, and severe comorbidity. The composite primary endpoint was the occurrence of any complication related to S aureus bloodstream infection (relapsing S aureus bloodstream infection, deep-seated infection, and mortality attributable to infection) within 90 days, assessed in the intention-to-treat population by clinical assessors who were masked to treatment assignment. Adverse events were assessed in all participants who received at least one dose of study medication (safety population). Due to slow recruitment, the scientific advisory committee decided on Jan 15, 2018, to stop the trial after 215 participants were randomly assigned (planned sample size was 430 participants) and to convert the planned interim analysis into the final analysis. The decision was taken without knowledge of outcome data, at a time when 126 participants were enrolled. The new sample size accommodated a non-inferiority margin of 10%; to claim non-inferiority, the upper bound of the 95% CI for the treatment difference (stratified by centre) had to be below 10 percentage points. The trial is closed to recruitment and is registered with ClinicalTrials.gov (NCT01792804), the German Clinical trials register (DRKS00004741), and EudraCT (2013-000577-77). FINDINGS Of 5063 patients with S aureus bloodstream infection assessed for eligibility, 213 were randomly assigned to switch to oral therapy (n=108) or to continue intravenous therapy (n=105). Mean age was 63·5 (SD 17·2) years and 148 (69%) participants were male and 65 (31%) were female. In the oral switch group, 14 (13%) participants met the primary endpoint versus 13 (12%) in the intravenous group, with a treatment difference of 0·7 percentage points (95% CI -7·8 to 9·1; p=0·013). In the oral switch group, 36 (34%) of 107 participants in the safety population had at least one serious adverse event compared with 27 (26%) of 103 participants in the intravenous group (p=0·29). INTERPRETATION Oral switch antimicrobial therapy was non-inferior to intravenous standard therapy in participants with low-risk S aureus bloodstream infection. However, it is necessary to carefully assess patients for signs and symptoms of complicated S aureus bloodstream infection at the time of presentation and thereafter before considering early oral switch therapy.

Abstract
BACKGROUND The aim of this study was to determine differences between patients who underwent surgical treatment and those who underwent nonsurgical treatment of vertebral osteomyelitis (VO) and to identify potential factors influencing treatment failure (death and/or recurrence within 1 year). METHODS We performed a retrospective analysis of clinical data prospectively collected from patients treated for VO between 2008 and 2020. The decision between surgical and nonsurgical treatment was made for each patient based on defined criteria. A 1:1 propensity score matching was performed to exclude confounders between the 2 treatments. Univariate and multivariable analyses were performed to identify potential risk factors for death and/or recurrence within the first year after VO diagnosis. RESULTS Forty-two patients (11.8%) were treated nonsurgically and 313 patients (88.2%) underwent surgery. A higher percentage of the surgically treated patients than the nonsurgically treated patients had an American Society of Anesthesiologists score of >2 (69.0% versus 47.5%; p = 0.007), and the thoracic spine was affected more often in the surgical group (30.4% versus 11.9%; p = 0.013). Endocarditis was detected significantly more often in the nonsurgically treated patients (14.3% versus 4.2%; p = 0.018). The recurrence rate was 3 times higher in the nonsurgically treated patients (16.7% versus 5.4%; p = 0.017), but this difference was no longer detectable after propensity matching. After matching, the nonsurgically treated patients showed an almost 7-fold higher 1-year mortality rate (25.0% versus 3.7%; p = 0.018) and an almost 3-fold higher rate of treatment failure (42.9% versus 14.8%; p = 0.022). Multivariable analysis revealed nonsurgical treatment and bacteremia to be independent risk factors for treatment failure. CONCLUSIONS In our matched cohort of patients with VO, surgical intervention resulted in a significantly lower rate of treatment failure (death and/or recurrence within 1 year) compared with nonsurgical intervention. Furthermore, nonsurgical treatment was an independent risk factor for treatment failure. LEVEL OF EVIDENCE Therapeutic Level III .

Abstract
PURPOSE Patients seen by infectious disease (ID) specialists are more complex compared to patients treated by other subspecialities according to Tonelli et al. (2018). However, larger studies on the complexity of patients related to the involvement of ID consultation services are missing. METHODS Data of patients being treated in 2015 and 2019 in four different German university hospitals was retrospectively collected. Data were collected from the hospitals' software system and included whether the patients received an ID consultation as well as patient clinical complexity level (PCCL), case mix index (CMI) and length of stay (LOS) as a measurement for the patients' complexity. Furthermore, a comparison of patients with distinct infectious diseases treated with or without an ID consultation was initiated. RESULTS In total, 215.915 patients were included in the study, 3% (n = 6311) of those were seen by an ID consultant. Patients receiving ID consultations had a significantly (p < 0.05) higher PCCL (median 4 vs. 0), CMI (median 3,8 vs. 1,1) and deviation of the expected mean LOS (median 7 days vs. 0 days) than patients in the control group. No differences among hospitals or between years were observed. Comparing patients with distinct infectious diseases treated with or without an ID consultation, the differences were confirmed throughout the groups. CONCLUSION Patients receiving ID consultations are highly complex, frequently need further treatment after discharge and have a high economic impact. Thus, ID specialists should be clinically trained in a broad spectrum of diseases and treating these complex patients should be sufficiently remunerated.

Abstract
OBJECTIVE This study aimed to compare clinical characteristics and quality of life (QoL) after vertebral osteomyelitis (VO) based on the status of pathogen detection in microbiological sampling. METHODS We conducted a post hoc data analysis from a prospective single-center study in a tertiary referral hospital, including VO patients from 2008 to 2020. Data were collected preoperatively (T0) and 1-year post surgery (T1). The primary outcome was QoL, assessed with the Oswestry Disability Index and Core Outcome Measures Index. RESULTS Data from 133 patients with surgically treated thoracic or lumbar VO were evaluated. The pathogen was detected from cultured intraoperative samples in 100 (75.2%) patients (group 1). Culture remained negative in 33 (24.8%) patients (group 2). Quality of life did not differ significantly between the groups at T1. We observed higher preoperative C-reactive protein values and higher rates of spinal empyema at T0 in group 1. CONCLUSION Quality of life improved significantly for all patients at T1, but scores remained comparable to those reported by patients with chronic back pain. Quality of life was not affected by pathogen detection. However, attempts to detect pathogens are still indicated due to the concomitant findings, including bacteremia and epidural abscesses, along with the advantages of targeted antibiotic therapy. The most critical step for detection may be avoiding pre-sampling antibiotic administration. Cite this article as: Beyer F, Wenk B, Jung N, Bredow J, Eysel P, Yagdiran A.

Abstract
Infectious medicine faces a variety of challenges, such as the increase in antibiotic resistance and the emergence and spread of infectious diseases fueled by climate change and globalization. Precision medicine can provide solutions to many of these challenges. Since an untargeted request for diagnostic tests can lead to test results without clinical relevance, which can increase the use of non-indicated antibiotics, the principle aimed at is: targeted diagnostics (the right test) and consideration of patient characteristics (the right person) to optimize management (the right action). At the same time, one must always decide whether empirical therapy must be immediately initiated, even if the results of the initiated diagnostics are not yet available. In addition, many new diagnostics as well as therapies have recently been developed for the rapid detection and more specific treatment of bacterial infections. Molecular genetic methods, which offer more rapid results than classical bacterial cultures, are gaining ground as new diagnostics. New therapeutics such as bacteriophages, antibodies or antibacterial peptides allow increasingly precise treatment of certain bacterial infections. Precision medicine will also play an increasingly important role in infectious medicine in the future.

Abstract
PURPOSE Antistaphylococcal penicillins and cefazolin have been used as first line therapy in Methicillin-susceptible Staphylococcus aureus bloodstream infection. While efficacy of both regimens seems to be similar, the compounds may differ with regard to tolerability. This study aims to describe the clinical use of cefazolin and flucloxacillin, focussing on discontinuation or change of anti-infective agent due to adverse events. METHODS This observational prospective study was conducted at two German tertiary care centres with an internal recommendation of flucloxacillin for MSSA-BSI in one, and of cefazolin in the other centre. Adverse events were registered weekly under treatment and at a 90-day follow-up. Descriptive analysis was complemented by a propensity score analysis comparing adverse events (stratified rank-based test applied to the sum of Common Terminology Criteria for adverse events ratings per patient). RESULTS Of 71 patients included, therapy was initiated with flucloxacillin in 56 (79%), and with cefazolin in 15 (21%). The propensity score analysis indicates a statistically significant difference concerning the severity of adverse events between the treatment groups in favour of cefazolin (p = 0.019). Adverse events led to discontinuation of flucloxacillin in 7 individuals (13% of all patients receiving flucloxacillin). Clinical outcome was not different among treatment groups. CONCLUSION Using cefazolin rather than flucloxacillin as a first line agent for treatment of MSSA-BSI is supported by these clinical data.

Abstract
BACKGROUND In Germany, a total of 38 547 heart valve procedures were performed in 2022. With a growing number of patients undergoing the surgical and interventional implantation of heart valves, the incidence of prosthetic endocarditis is also rising. METHODS We summarize the current state of the prophylaxis, diagnosis, and treatment of prosthetic endocarditis in a selective review of the literature. RESULTS Prosthetic endocarditis accounts for 10-30% of all cases of endocarditis. As its echocardiographic and microbiologic findings are often less specific than those of native endocarditis, its diagnosis now increasingly relies on alternative imaging modalities such as F-18-FDG PET-CT. Anti-infective and surgical treatment are made more difficult by biofilm formation on the prosthetic valve and the frequent formation of perivalvular abscesses. CONCLUSION Increased awareness of this clinical entity in the outpatient setting will promote the earlier initiation of appropriate diagnostic studies. Proper diagnostic evaluation is an essential prerequisite for the early detection and timely treatment of prosthetic endocarditis, with the goal of preventing progressive destruction and thus improving the outcome. Preventive and educative measures should be intensified, and certified, multidisciplinary endocarditis teams should be established. Antibiotic prophylaxis is now given much more restrictively than in earlier years; the risk of infection must be weighed against the potential development of both individual and collective resistance to antibiotic drugs.

Abstract
INTRODUCTION Surgical classifications for spondylodiscitis (SD) typically include radiologic features and the status of neurologic impairment. Clinical factors such as preoperative pain, function/disability, overall quality of life (QoL), and risk of recurrence and mortality, which are necessary for a comprehensive assessment of SD and measurement of treatment success, are not considered. There is a lack of external validation of SD classifications. The aim of this study was to validate classifications of SD and to correlate these classifications with the above clinical factors. METHODS One hundred fourteen patients from a prospective SD register (2008-2020) with available imaging, preoperative neurologic status, backpain, function/disability data (Oswestry Disability Index and Core Outcome Measures Index), QoL data (Short Form 36, European Quality-of-life Questionnaire), and a 1-year follow-up were retrospectively classified according to Akbar, Homagk, and Pola classifications. Interrater reliability, correlation among classifications, and correlation between classifications and QoL were calculated. RESULTS Interrater reliability was κ = 0.83 for Akbar, κ = 0.94 for Homagk, and κ = 0.99 for Pola. The correlation of Akbar with Pola and Homagk was moderate (ρ s = 0.47; ρ s = 0.46) and high between Pola and Homagk (ρ s = 0.7). No notable correlation was observed between any of the classifications and preoperative Oswestry Disability Index, Core Outcome Measures Index, QoL, mortality, and recurrence within 1 year. Only a weak correlation was observed between Homagk and preoperative leg pain and back pain. CONCLUSION Available SD classifications have a very good interrater reliability and moderate-to-high correlation with each other but lack correlation with preoperative pain, function/disability, and overall QoL. Because these factors are important for a comprehensive assessment of SD in severity, decision making, and prognosis, they should be included in future SD classifications. This could allow for more comprehensive treatment algorithms. LEVEL OF EVIDENCE Level II. Diagnostic study = prospective cohort study; development of diagnostic criteria.

Abstract
STUDY DESIGN retrospective study. OBJECTIVES In addition to surgical treatment of spinal epidural abscesses (SEA), a conservative, medical treatment for patients without acute neurologic deficits has been proposed. However, the risk factors for neurologic deficits are unclear. This study aims to identify factors predisposing patients with SEA to neurological impairment. METHODS All patients treated for SEA between 2008 and 2021 were identified from a prospective vertebral-osteomyelitis registry of a tertiary referral centre. Patient demographics, comorbidities, pathogens, degree of osseous destruction, location of SEA and preoperative neurologic status were retrospectively collected. Differences between patients with (Group 1) and without (Group 2) pretreatment neurologic deficits were assessed by univariate and logistic regression analysis. RESULTS A total of 140 patients with SEA were included. Forty-three patients (31%) had a neurologic deficit and 97 patients (69%) had no neurologic deficit prior to therapy. The prevalence of diabetes mellitus (35% vs 19%, P = .03), median visual analogue scale leg pain (8 vs 5, P = .01), median American Society of Anesthesiologists (ASA) Score (3 vs 2.6, P = .003) and mean Body-Mass-Index (29 vs 26, P = .02) differed between Group 1 and 2 in univariate analysis. In multivariable analysis, diabetes mellitus (odds ratio = 2.7), female sex (odds ratio = 2.5) and ASA-Score (odds ratio = 2.4) were significant contributors for neurologic deficits. CONCLUSIONS In patients with a SEA without neurologic deficits, the ASA score and diabetes mellitus should be considered, especially in female patients. These patients may be at a higher risk for developing a neurologic deficit and may benefit from an early surgical treatment.

Abstract
The humoral and cellular immune responses to antigen stimulation, vaccinations and infections differ between women and men. Genetic, epigenetic and hormonal factors contribute to the sex-specific immunity. The expression of genes on the X‑chromosome and the effect of sex hormones substantially influence the immune defence against infections. Females show stronger cellular and humoral immune responses to infections than males, but the enhanced immune response often leads to aberrant inflammatory reactions and autoimmune diseases. Men are principally more prone to bacterial, viral and fungal infections and more often show severe disease courses. In contrast, a more reactive female immune system results in significantly more adverse reactions to vaccinations. In order to be able to better identify the multiple sex-specific that have an influence on the immune system, sex-specific differences should be investigated in a differentiated way. The better understanding of the sex-specific differences in the immune response will have a long-term influence on the prevention, diagnostics and treatment of infectious diseases, and will ultimately contribute to improving healthcare of both women and men.

Abstract
OBJECTIVE This study aimed to determine threshold values of validated quality of life (QoL) scores, including Oswestry Disability Index (ODI) and Core Outcome Measures Index (COMI), for predicting a successful outcome following surgical treatment of lumbar spondylodiscitis (LS). METHODS Patients with lumbar spondylodiscitis (LS) undergoing surgery in a tertiary referral hospital were included prospectively from 2008-2019. Data were collected both before surgery (T0) and one year after surgery (T1). QoL was measured using ODI and COMI. The successful clinical outcome was defined by the combination of the following four criteria: no recurrence of spondylodiscitis, back pain ≤4 on visual analogue scale or relief of ≥3 points, absence of LS-related neurological deficit, and radiological fusion of the affected segment. For subgroup analysis, group 1 consisted of patients with a favorable treatment outcome (meeting all four criteria), while group 2 included patients with unfavorable treatment outcome (meeting ≤3 criteria). RESULTS Ninety-two LS patients (median age = 66 years; age range = 57-74) were analyzed. QoL scores improved significantly. Threshold values for the ODI and COMI were calculated at 35 and 4.2 points, respectively. The area under curve for the ODI was 0.856 (95%-CI 0.767- 0.945; P<0.001) and 0.839 (95% CI-0.749-0.928; P<0.001) for the COMI score. Eighty percent of patients achieved a favorable outcome. CONCLUSION Objective measurement and evaluation of successful surgical treatment of spondylodiscitis require defined thresholds of quality of life scores. We were able to define such thresholds for Oswestry Disability Index and Core Outcome Measures Index. These can be useful to assess clinically relevant changes and therefore allow a more precise estimation of the post-surgical outcome. LEVEL OF EVIDENCE Level II, Prognostic study.

Abstract
PURPOSE Spinal injections are increasingly used for back pain treatment. Vertebral osteomyelitis (VO) after spinal injection (SIVO) is rare, but patient characteristics and outcome have not been well characterized. The aim of this study was to assess patient characteristics of SIVO in comparison to patients with native vertebral osteomyelitis (NVO) and to determine predictors for 1-year survival. METHODS This is a single-center cohort study from a tertiary referral hospital. This is a retrospective analysis of Patients with VO who were prospectively enrolled into a spine registry from 2008 to 2019. Student's t-test, Kruskal-Wallis test or Chi-square test were applied for group comparisons. Survival analysis was performed using a log-rank test and a multivariable Cox regression model. RESULTS 283 VO patients were enrolled in the study, of whom 44 (15.5%) had SIVO and 239 (84.5%) NVO. Patients with SIVO were significantly younger, had a lower Charlson comorbidity index and a shorter hospital stay compared to NVO. They also showed a higher rate of psoas abscesses and spinal empyema (38.6% [SIVO] vs. 20.9% [NVO]). Staphylococcus aureus (27%) and coagulase-negative staphylococci (CNS) (25%) were equally often detected in SIVO while S. aureus was more frequently than CNS in NVO (38.1% vs. 7.9%).Patients with SIVO (P = 0.04) had a higher 1-year survival rate (Fig. 1). After multivariate analysis, ASA score was associated with a lower 1-year survival in VO. CONCLUSION The results from this study emphasize unique clinical features of SIVO, which warrant that SIVO should be estimated as a separate entity of VO.

Abstract
STUDY DESIGN Review article. OBJECTIVES A review of literature on the treatment of pyogenic spondylodiscitis in geriatric patients was performed with the aim to give an overview about these special patients and a recommendation on necessary diagnostics as well as conservative and operative treatment options. METHODS A systematic computerized literature search was done by the spondylodiscitis working group of the German Society for Orthopedics and Trauma Surgery. RESULTS Spondylodiscitis has an increasing incidence by age with a peak at 75 years or older. The 1-year mortality without an appropriate treatment is with 15 to 20% extremely high. Pathogen detection is the essential diagnostic step and the basis for a sufficient antibiotic treatment. Geriatric patients have initially less elevated inflammatory parameters. Compared to younger patients. They have a longer length of hospital stay and take longer for CRP normalization. Even the outcome between conservative and operative treatment is comparable after one year. Patients with spinal instability, immobilizing pain, epidural abscess, and newly emerged neurological deficits should be considered for operative treatment. CONCLUSIONS The treatment of geriatric patients with pyogenic spondylodiscitis must take into account that these patients usually have multiple comorbidities. The main goals are resistance-based antibiotics and the shortest possible time of immobilization of the patient.

Specialized palliative care for hospitalized patients with SARS-CoV-2 infection: an analysis of the LEOSS registry. Infection 2023:10.1007/s15010-023-02020-z. [PMID: 36952127 PMCID: PMC10034879 DOI: 10.1007/s15010-023-02020-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2023] [Accepted: 03/11/2023] [Indexed: 03/24/2023]
Abstract
PURPOSE Symptom control for patients who were severely ill or dying from COVID-19 was paramount while resources were strained and infection control measures were in place. We aimed to describe the characteristics of SARS-CoV-2 infected patients who received specialized palliative care (SPC) and the type of SPC provided in a larger cohort. METHODS From the multi-centre cohort study Lean European Open Survey on SARS-CoV-2 infected patients (LEOSS), data of patients hospitalized with SARS-CoV-2 infection documented between July 2020 and October 2021 were analysed. RESULTS 273/7292 patients (3.7%) received SPC. Those receiving SPC were older and suffered more often from comorbidities, but 59% presented with an estimated life expectancy > 1 year. Main symptoms were dyspnoea, delirium, and excessive tiredness. 224/273 patients (82%) died during the hospital stay compared to 789/7019 (11%) without SPC. Symptom control was provided most common (223/273; 95%), followed by family and psychological support (50% resp. 43%). Personal contact with friends or relatives before or during the dying phase was more often documented in patients receiving SPC compared to patients without SPC (52% vs. 30%). CONCLUSION In 3.7% of SARS-CoV-2 infected hospitalized patients, the burden of the acute infection triggered palliative care involvement. Besides complex symptom management, SPC professionals also focused on psychosocial and family issues and aimed to enable personal contacts of dying patients with their family. The data underpin the need for further involvement of SPC in SARS-CoV-2 infected patients but also in other severe chronic infectious diseases.

Abstract
Bone and joint infections are becoming of great concern in an elderly population with growing numbers of prosthetic joints and comorbidities. This paper summarizes recently published literature on periprosthetic joint infections, vertebral osteomyelitis and diabetic foot infections. According to a new study, in the presence of a hematogenous periprosthetic infection and other inserted joint prostheses that are unremarkable on clinical examination, further invasive or imaging diagnostics may not be necessary. Periprosthetic infections that occur late (> 3 months after joint installation) have a worse outcome. New studies tried to identify factors when prosthesis preservation might still be an option. A new randomized landmark trial from France failed to show non-inferiority for 6 versus 12 weeks of therapy length. Thus, it can be assumed that this will currently become the standard therapy length for all surgical modalities (retention or replacement). Vertebral osteomyelitis is a rather rare bone infection, but the incidence has continued to rise sharply in recent years. A retrospective study from Korea provides information on the distribution of pathogens in different age groups and with selected comorbidities; this could help in the selection of an empiric therapy when pathogen identification is not successful before starting the treatment. The guidelines by the "International Working Group on the Diabetic Foot (IWGDF)" have been updated with a slightly different classification. New practice recommendations of the German society of diabetology emphasize an early interdisciplinary interprofessional management. Empirical therapy continues to be based on the severity of the infection and other risk factors (such as previous therapies or ischemia). Microbiological diagnosis from tissue samples is described as superior to smears. According to a randomized pilot study, 3 weeks therapy length for osteomyelitis after debridement appears to be noninferior to 6 weeks.

Choosing Wisely internationally - helpful recommendations for antimicrobial stewardship! Infection 2023; 51:567-581. [PMID: 36840828 DOI: 10.1007/s15010-023-02005-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/05/2023] [Accepted: 02/14/2023] [Indexed: 02/26/2023]
Abstract
PURPOSE Antimicrobial resistance poses a major threat to human health globally and antibiotic overuse is a main driver of resistance. Antimicrobial stewardship (AMS) was developed to improve the rationale use of antibiotics. The Choosing Wisely campaign was initiated to ameliorate medical practice through avoidance of unnecessary diagnostic and therapeutic procedures. Our objective was to give an overview on the Choosing Wisely recommendations related to AMS practices from a selection of different countries in order to define future needs. METHODS We evaluated the seven countries already analyzed for Choosing Wisely recommendations related to topics of infectious medicine before. Finally, we included five of the former countries (Australia/New Zealand, Canada, Italy, Switzerland, and USA) and Germany with easily accessible recommendations and selected those related to six categories of AMS as following: diagnostics, indication, choice of antiinfective drugs, dosing, application and duration of therapy. RESULTS In total, 213 recommendations could be extracted related to AMS for the six countries and were matched to the chosen categories. Interestingly, no recommendations were found for the category "dosing." Topics related to indication and diagnostics were most frequently found with 85 and 78 recommendations, respectively. Perioperative prophylaxis was a frequently addressed issue - both related to application, indication and duration. Avoiding antibiotic treatment of asymptomatic bacteriuria and upper respiratory tract infections were central topics of all countries. CONCLUSION AMS is an important strategy to fight increasing resistance and is frequently addressed by Choosing Wisely recommendations of different countries. Similar issues are considered important in the selected countries.

[Development and validation of potential structure indicators for clinical infectious disease (ID) care in German hospitals during the COVID-19 pandemic]. ZEITSCHRIFT FUR EVIDENZ, FORTBILDUNG UND QUALITAT IM GESUNDHEITSWESEN 2023; 176:12-21. [PMID: 36754716 PMCID: PMC9901538 DOI: 10.1016/j.zefq.2022.11.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 02/02/2022] [Revised: 11/07/2022] [Accepted: 11/15/2022] [Indexed: 02/09/2023]
Abstract
INTRODUCTION This study describes the development and validation of structure indicators for clinical infectious disease (ID) care in German hospitals, which is important to adequately face the future challenges in ID medicine. METHODS A team of experts developed the structure indicators in a three-stage, multicriteria decision-making process: (1) identification of potential structure indicators based on a literature review, (2) written assessment process, and (3) face-to-face discussion to reach consensus and final selection of appropriate structure indicators. A field study was conducted to assess the developed structure indicators. A score based on the structure indicators was determined for each hospital and validated via receiver operator characteristic (ROC) curves using externally validated ID expertise (German Society of ID (DGI) Centre). RESULTS Based on a list of 45 potential structure indicators, 18 suitable indicators were developed for clinical ID care structures in German hospitals. Out of these, ten key indicators were defined for the general and coronavirus disease 2019- (COVID-19-) specific clinical ID care structures. In the field survey of clinical ID care provision for COVID-19 patients in 40 German hospitals, the participating facilities achieved 0 to 9 points (median 4) in the determined score. The area under the ROC curve was 0.893 (95% CI: 0.797, 0.988; p < 0.001). DISCUSSION/CONCLUSION The structure indicators developed within the framework of a transparent and established development process can be used in the future to both capture the current state and future developments of ID care quality in Germany and enable comparisons.

Short-course versus long-course antibiotic treatment for uncomplicated vancomycin-resistant enterococcal bacteraemia: a retrospective multicentre cohort study. Clin Microbiol Infect 2023; 29:200-207. [PMID: 36087919 DOI: 10.1016/j.cmi.2022.08.023] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/26/2022] [Revised: 08/10/2022] [Accepted: 08/29/2022] [Indexed: 02/07/2023]
Abstract
OBJECTIVES The optimal treatment duration for vancomycin-resistant enterococcal (VRE) bacteraemia is still a matter of debate. The aim of the present study was to compare short-course (≤9 days) and long-course (≥10 days) antibiotic treatments in hospitalized adult patients with uncomplicated VRE bacteraemia. METHODS This retrospective study was conducted in four university hospitals in Germany. Adult patients with a positive blood culture for a VRE were screened from 1 January 2016 to 31 December 2018. Only patients who received a VRE-active antibiotic for at least 48 hours were included. The exclusion criteria were a survival of <10 days and a deep-seated source of infection requiring prolonged treatment. To compare the outcome of short-course therapy with that of long-course therapy, 30-day and 90-day overall mortality, relapse within 90 days, duration of hospitalization, and potential antibiotic-related adverse events were analysed by inverse probability of treatment weighting using the propensity score and by additional covariate adjustment. RESULTS Of the 363 patients screened, 219 (60.3%) patients were included in the final analysis. Among them, 48 (21.9%) patients had underlying haematological diseases. Seventy-eight (35.6%) patients received short-course treatment (median, 7 days; interquartile range, 5-8 days) and 141 (64.4%) patients received long-course treatment (median, 15 days; interquartile range, 12-23.5 days). Thirty-day mortality was similar in both groups (19.2% vs. 22.0%; adjusted OR, 1.15; p 0.773). Duration of hospitalization (in total and after onset of bacteraemia) was significantly shorter (p < 0.05) in the short-course treatment group, whereas other secondary outcome parameters did not differ between both groups. DISCUSSION Our study suggests that short-course treatment might not be associated with a worse outcome in patients with uncomplicated VRE bacteraemia.

Abstract
PURPOSE Ureaplasma species are associated with urogenital infections, infertility and adverse pregnancy outcomes as well as neonatal infections. Involvement of the central nervous system in adults is extremely rare. We report an unusual case of a brain abscess secondary to otitis media with Ureaplasma parvum in a patient with granulomatosis with polyangiitis (GPA). METHODS Imaging and laboratory findings, treatment decisions, and outcome of this case are explicated. RESULTS A young adult with GPA presented with progredient earache after ambulant diagnosis of otitis media. Despite different courses of broad-spectrum antibiotic therapy, she developed meningoencephalitis due to mastoiditis following temporal abscess formation. Mastoidectomy and neurosurgical abscess removal were performed. Standard cultures of cerebrospinal fluid, blood and intracranial abscess material, as well as polymerase chain reaction (PCR) for common bacterial and viral meningitis pathogens remained negative. Only eubacterial PCR of intracranial abscess material returned positive for Ureaplasma parvum. The patient finally improved under antibiotic therapy with moxifloxacin and doxycycline. CONCLUSION Ureaplasma species are rare causative pathogens in immunocompromised patients. They should be considered in patients with humoral immunodeficiencies with culture-negative infections failing standard therapy. Eubacterial PCR should be performed in early states of infection in these patients for immediate diagnosis and initiation of appropriate treatment to prevent adverse outcomes.

Abstract
Establishing the optimal treatment for COVID-19 patients remains challenging. Specifically, immunocompromised and pre-diseased patients are at high risk for severe disease course and face limited therapeutic options. Convalescent plasma (CP) has been considered as therapeutic approach, but reliable data are lacking, especially for high-risk patients. We performed a retrospective analysis of 55 hospitalized COVID-19 patients from University Hospital Duesseldorf (UKD) at high risk for disease progression, in a substantial proportion due to immunosuppression from cancer, solid organ transplantation, autoimmune disease, dialysis. A matched-pairs analysis (1:4) was performed with 220 patients from the Lean European Open Survey on SARS-CoV-2-infected Patients (LEOSS) who were treated or not treated with CP. Both cohorts had high mortality (UKD 41.8%, LEOSS 34.1%). A matched-pairs analysis showed no significant effect on mortality. CP administration before the formation of pulmonary infiltrates showed the lowest mortality in both cohorts (10%), whereas mortality in the complicated phase was 27.8%. CP administration during the critical phase revealed the highest mortality: UKD 60.9%, LEOSS 48.3%. In our cohort of COVID-19 patients with severe comorbidities CP did not significantly reduce mortality in a retrospective matched-pairs analysis. However, our data supports the concept that a reduction in mortality is achievable by early CP administration.

Abstract
Background
COVID-19 is a severe disease with a high need for intensive care treatment and a high mortality rate in hospitalized patients. The objective of this study was to describe and compare the clinical characteristics and the management of patients dying with SARS-CoV-2 infection in the acute medical and intensive care setting.
Methods
Descriptive analysis of dying patients enrolled in the Lean European Open Survey on SARS-CoV-2 Infected Patients (LEOSS), a non-interventional cohort study, between March 18 and November 18, 2020. Symptoms, comorbidities and management of patients, including palliative care involvement, were compared between general ward and intensive care unit (ICU) by univariate analysis.
Results
580/4310 (13%) SARS-CoV-2 infected patients died. Among 580 patients 67% were treated on ICU and 33% on a general ward. The spectrum of comorbidities and symptoms was broad with more comorbidities (≥ four comorbidities: 52% versus 25%) and a higher age distribution (>65 years: 98% versus 70%) in patients on the general ward. 69% of patients were in an at least complicated phase at diagnosis of the SARS-CoV-2 infection with a higher proportion of patients in a critical phase or dying the day of diagnosis treated on ICU (36% versus 11%). While most patients admitted to ICU came from home (71%), patients treated on the general ward came likewise from home and nursing home (44% respectively) and were more frequently on palliative care before admission (29% versus 7%). A palliative care team was involved in dying patients in 15%. Personal contacts were limited but more often documented in patients treated on ICU (68% versus 47%).
Conclusion
Patients dying with SARS-CoV-2 infection suffer from high symptom burden and often deteriorate early with a demand for ICU treatment. Therefor a demand for palliative care expertise with early involvement seems to exist.

What Do We Know about Spondylodiscitis in Children? A Retrospective Study. CHILDREN 2022; 9:children9081103.

Abstract
Pediatric spondylodiscitis (PSD) is a rare disease with a major impact on mobility and functional status. Data concerning demographic and microbiological characteristics, clinical course, treatment, and outcome are scarce. Therefore, the aim of this study was to present clinical experiences of a third-level hospital (2009–2019) in PSD and compare these with adult spondylodiscitis (ASD). Of a total of 10 PSD patients, most of the infants presented with unspecific pain such as hip pain or a limping, misleading an adequate diagnosis of spine origin. Eight patients could be treated conservatively whereas surgery was performed in two cases with one case of tuberculous PSD (tPSD). The causative agent was detected in three of the patients. The diagnosis of PSD is often difficult since clinical symptoms are unspecific and causative pathogens often remain undetected. Nevertheless, empirical anti-infective therapy also seems to be effective. Based on recent studies, clinicians should be encouraged to keep the duration of anti-infective therapy in children short. Since comorbidities are not presented in PSD it is unclear which children suffer from PSD; thus, studies are necessary to identify predisposing factors for PSD. In our study, PSD differs from ASD in diagnostic and especially in therapeutic aspects. Therefore, specific guidelines for PSD would be desirable.

Abstract
BACKGROUND Since the onset of the SARS CoV2 pandemic, protective and isolation measures had a strong impact on the care and support provided to seriously ill and dying people at the end-of-life. AIM Exploring bereaved relatives' experiences of end-of-life care during the SARS-CoV2 pandemic. DESIGN Qualitative interview study with bereaved relatives. PARTICIPANTS Thirty-two relatives of patients who died during the pandemic, regardless of infection with SARS-CoV2. RESULTS Three core categories were identified: needs, burden and best practice. Relatives wished for a contact person responsible for providing information on the medical and mental condition of their family members. The lack of information, of support by others and physical closeness due to the visiting restrictions, as well as not being able to say goodbye, were felt as burdens and led to emotional distress. However, case-by-case decisions were made and creative ways of staying in touch were experienced positively. CONCLUSIONS Our results indicate that the strong need for closeness when a family member was dying could not be met due to the pandemic. This led to suffering that can be prevented. Visits need to be facilitated by making considered decisions on a case-by-case basis. For easy communication with relatives, approaches should be made by healthcare professionals and support for virtual communication should be offered. Furthermore, the results of the study can help to implement or develop ideas to enable dignified farewells even during pandemics.

Abstract
PURPOSE Vertebral osteomyelitis (VO) is a severe clinical entity associated with significant morbidity and mortality. Several studies have showed that successful treatment of VO patients leads to significantly improved quality of life (QoL). Nevertheless, QoL levels of these patients remained below those of the general population. There are rarely studies focusing on predicting factors for favourable QoL after surgically treated VO. The aim of this study was to identify factors influencing positively the QoL of patients undergoing surgery for VO. METHODS We conducted a prospective monocentric study including surgically treated VO patients from 2008 to 2016. Data were collected before (T0) and 1 year (T1) after surgery. Primary outcome was favourable QoL defined as back pain with disability restricting normal life activity with a cutoff value ≥ 12 on Oswestry Disability Index (ODI). ETHICS Ethical approval was given by the Faculty of Medicine at the University of Cologne (09-182). RESULTS A total of 119 patients surviving 1 year after surgically treated VO were analysed. Favourable QoL was achieved in 35/119 patients. On multivariate analysis, younger age (hazard ratio = HR: 0.95; 95% CI 0.91-0.99; p = 0.022), lower albumin (HR: 0.9; 0.83-0.98; p = 0.019) an ASA score ≤ 2 (HR:4.24; 95%CI 1.42-12.68; p = 0.010), and a lower preoperative leg pain on the VAS (HR: 0.86; 95% CI 0.76-0.97; p = 0.018) were identified as independent risk factors for favourable QoL. Interestingly, the absence of neurological deficits was not predictive for a favourable outcome by means of QoL. CONCLUSION One-third of surgically treated VO patients (29%) in our cohort achieved favourable QoL by means of ODI. Our findings can facilitate an estimation of the prognosis when informing the patient before surgery, and underscore that spine disability questionnaires, such as ODI, measuring QoL, are mandatory to evaluate comprehensively the outcome of this entity.

The Burden of Vertebral Osteomyelitis—An Analysis of the Workforce before and after Treatment. J Clin Med 2022; 11:jcm11041095.

Abstract
Although vertebral osteomyelitis (VO) has a major impact on morbidity, functional status, and quality of life, data concerning the influence on the patient’s ability to work (ATW) are lacking. Therefore, the aim of this study was to analyze the work status after VO-treatment as well as risk factors associated with loss of the ATW. We conducted a post-hoc analysis of data from a prospective VO-registry (2008–2019) supplemented by workforce data. Primary endpoint was the work status after one year (T1). Univariate analysis comparing patients’ characteristics “at-work” versus “not-at-work” at T1 was performed. Of a total of 335 VO-patients, n = 52 (16%) were part of the workforce at time of diagnosis (T0), of which 22 (42%) failed to be part of the workforce at T1. A higher number of comorbidities and a body mass index (BMI) < 25 kg/m2 were associated with a reduced ATW. VO in working age patients is a debilitating condition and associated with reduced patients’ ATW. Patients engaged in heavy physical work mostly had a BMI < 25 kg/m2 and therefore were more severely affected and no longer able to keep their workforce. More support in retraining should be offered after successful treatment to maintain ATW and reduce the socio-economic burden.

Abstract
Background In the SARS-CoV-2 pandemic, general and specialist Palliative Care (PC) plays an essential role in health care, contributing to symptom control, psycho-social support, and providing support in complex decision making. Numbers of COVID-19 related deaths have recently increased demanding more palliative care input. Also, the pandemic impacts on palliative care for non-COVID-19 patients. Strategies on the care for seriously ill and dying people in pandemic times are lacking. Therefore, the program ‘Palliative care in Pandemics’ (PallPan) aims to develop and consent a national pandemic plan for the care of seriously ill and dying adults and their informal carers in pandemics including (a) guidance for generalist and specialist palliative care of patients with and without SARS-CoV-2 infections on the micro, meso and macro level, (b) collection and development of information material for an online platform, and (c) identification of variables and research questions on palliative care in pandemics for the national pandemic cohort network (NAPKON). Methods Mixed-methods project including ten work packages conducting (online) surveys and qualitative interviews to explore and describe i) experiences and burden of patients (with/without SARS-CoV-2 infection) and their relatives, ii) experiences, challenges and potential solutions of health care professionals, stakeholders and decision makers during the SARS-CoV-2 pandemic. The work package results inform the development of a consensus-based guidance. In addition, best practice examples and relevant literature will be collected and variables for data collection identified. Discussion For a future “pandemic preparedness” national and international recommendations and concepts for the care of severely ill and dying people are necessary considering both generalist and specialist palliative care in the home care and inpatient setting.

[PMID: 34933239 DOI: 10.1016/j.cyto.2021.155782] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/22/2021] [Revised: 11/24/2021] [Accepted: 12/04/2021] [Indexed: 11/03/2022]
Abstract
Vertebral osteomyelitis (VO) is a primary infection of the endplates of the vertebral bodies with secondary infection of the adjacent intervertebral discs. Diagnosis is often delayed due to unspecific symptoms and a lack of specific infection markers. In this prospective study, we determined the suitability of 27 cytokines for the discrimination of VO and degenerative diseases of the spine and compared its diagnostic potential in relation to the C-reactive protein (CRP), which is widely used as a non-specific inflammation marker in clinical diagnostics. The patients included in this study underwent surgical stabilization of the lumbar and/or thoracic spine with removal of 1 or more affected intervertebral discs, as therapy for VO (n = 16) or for erosive osteochondrosis (EO, control group, n = 20). We evaluated the cytokine and CRP concentrations before (pre-OP = -20-0d where 0 means the day of surgery) and after surgery (post-OP) on days 3-5, 6-11, 40-56, and 63-142. Compared to the control patients pre-OP, a significantly higher elevation of the 4 cytokines IL-6, IL-8, IL-12 (p70), and VEGF as well as CRP were found in the VO patients, showing an area under the curve > 0.80 pre-OP. No significant differences were observed between VO patients with high and low virulent bacteria with respect to all 5 elevated biomarkers. This is the first prospective study in which a broad spectrum of 27 cytokines was analysed via multiplex assay using sera from patients with and without VO. Our results show that, in addition to CRP, 4 different cytokines were significantly altered in VO but not control patients. The results implicate that these candidate cytokines may be used in a multiplex assay for discrimination between VO and degenerative diseases of the spine.

Alveolar echinococcosis as a cause of vertebral osteomyelitis and soft tissue infection with recurrent cutaneous fistula formation. Int J Infect Dis 2021; 114:31-33. [PMID: 34715358 DOI: 10.1016/j.ijid.2021.10.041] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/20/2021] [Revised: 10/15/2021] [Accepted: 10/18/2021] [Indexed: 10/20/2022] Open
Abstract
Echinococcus multilocularis is endemic in Germany. However, alveolar echinococcosis is a rare disease. Most commonly the parasite affects the liver, behaving like a malignant tumour. Bones are affected in less than 2% of cases. We report a case of vertebral osteomyelitis accompanied by recurrent cutaneous fistula formation.

"Saying goodbye all alone with no close support was difficult"- Dying during the COVID-19 pandemic: an online survey among bereaved relatives about end-of-life care for patients with or without SARS-CoV2 infection. BMC Health Serv Res 2021; 21:998. [PMID: 34551766 PMCID: PMC8455806 DOI: 10.1186/s12913-021-06987-z] [Citation(s) in RCA: 27] [Impact Index Per Article: 9.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/21/2021] [Accepted: 08/24/2021] [Indexed: 01/29/2023] Open
Abstract
BACKGROUND During the SARS-CoV2 pandemic, protection measures, as well as visiting restrictions, had a severe impact on seriously ill and dying patients and their relatives. The study aims to describe the experiences of bereaved relatives of patients who died during the SARS-CoV2 pandemic, regardless of whether patients were infected with SARS-CoV2 or not. As part of this, experiences related to patients' end-of-life care, saying goodbye, visiting restrictions and communication with the healthcare team were assessed. METHODS An open observational post-bereavement online survey with free text options was conducted with 81 bereaved relatives from people who died during the pandemic in Germany, with and without SARS-CoV2 diagnosis. RESULTS 67/81 of the bereaved relatives were female, with a mean age of 57.2 years. 50/81 decedents were women, with a mean age of 82.4 years. The main underlying diseases causing death were cardiovascular diseases or cancer. Only 7/81 of the patients were infected with SARS-CoV2. 58/81 of the relatives felt burdened by the visiting restrictions and 60/81 suffered from pandemic-related stress. 10 of the patients died alone due to visiting restrictions. The burden for relatives in the hospital setting was higher compared to relatives of patients who died at home. 45/81 and 44/81 relatives respectively reported that physicians and nurses had time to discuss the patient's condition. Nevertheless, relatives reported a lack of proactive communication from the healthcare professionals. CONCLUSIONS Visits of relatives play a major role in the care of the dying and have an impact on the bereavement of relatives. Visits must be facilitated, allowing physical contact. Additionally, virtual contact with the patients and open, empathetic communication on the part of healthcare professionals is needed.

Long-lived macrophage reprogramming drives spike protein-mediated inflammasome activation in COVID-19. EMBO Mol Med 2021; 13:e14150. [PMID: 34133077 PMCID: PMC8350892 DOI: 10.15252/emmm.202114150] [Citation(s) in RCA: 83] [Impact Index Per Article: 27.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/17/2021] [Revised: 05/26/2021] [Accepted: 05/28/2021] [Indexed: 01/12/2023] Open
Abstract
Innate immunity triggers responsible for viral control or hyperinflammation in COVID-19 are largely unknown. Here we show that the SARS-CoV-2 spike protein (S-protein) primes inflammasome formation and release of mature interleukin-1β (IL-1β) in macrophages derived from COVID-19 patients but not in macrophages from healthy SARS-CoV-2 naïve individuals. Furthermore, longitudinal analyses reveal robust S-protein-driven inflammasome activation in macrophages isolated from convalescent COVID-19 patients, which correlates with distinct epigenetic and gene expression signatures suggesting innate immune memory after recovery from COVID-19. Importantly, we show that S-protein-driven IL-1β secretion from patient-derived macrophages requires non-specific monocyte pre-activation in vivo to trigger NLRP3-inflammasome signaling. Our findings reveal that SARS-CoV-2 infection causes profound and long-lived reprogramming of macrophages resulting in augmented immunogenicity of the SARS-CoV-2 S-protein, a major vaccine antigen and potent driver of adaptive and innate immune signaling.

Abstract
Isolation of confirmed or suspected coronavirus disease 2019 (COVID-19) cases is essential but, as symptoms of COVID-19 are non-specific and test results not immediately available, case identification at admission remains challenging. To inform optimization of triage algorithms, patient flow and patient care, we analyzed characteristics of patients admitted to an isolation ward, both severe acute respiratory syndrome coronavirus 2019 (SARS-CoV-2) positive patients and patients in which initial suspicion was not confirmed after appropriate testing.Data from patients with confirmed or suspected COVID-19 treated in an isolation unit were analyzed retrospectively. Symptoms, comorbidities and clinical findings were analyzed descriptively and associations between patient characteristics and final SARS-CoV-2 status were assessed using univariate regression.Eighty three patients (49 SARS-CoV-2 negative and 34 positive) were included in the final analysis. Of initially suspected COVID-19 cases, 59% proved to be SARS-CoV-2-negative. These patients had more comorbidities (Charlson Comorbidity Index median 5(interquartile range [IQR] 2.5, 7) vs 2.7(IQR 1, 4)), and higher proportion of active malignancy than patients with confirmed COVID-19 (47% vs 15%; P = .004), while immunosuppression was frequent in both patient groups (20% vs 21%; P = .984). Of SARS-CoV-2 negative patients, 31% were diagnosed with non-infectious diseases.A high proportion of patients (59%) triaged to the isolation unit were tested negative for SARS-CoV-2. Of these, many suffered from active malignancy (47%) and were immunosuppressed (20%). Non-infectious diseases were diagnosed in 31%, highlighting the need for appropriate patient flow, timely expert medical care including evaluation for differential diagnostics while providing isolation and ruling out of COVID-19 in these patients with complex underlying diseases.

Abstract
BACKGROUND The objective of this study was to identify clinical risk factors for COVID-19 in a German outpatient fever clinic that allow distinction of SARS-CoV-2 infected patients from other patients with flu-like symptoms. METHODS This is a retrospective, single-centre cohort study. Patients were included visiting the fever clinic from 4th of April 2020 to 15th of May 2020. Symptoms, comorbidities, and socio-demographic factors were recorded in a standardized fashion. Multivariate logistic regression was used to identify risk factors of COVID-19, on the bases of those a model discrimination was assessed using area under the receiver operation curves (AUROC). RESULTS The final analysis included 930 patients, of which 74 (8%) had COVID-19. Anosmia (OR 10.71; CI 6.07-18.9) and ageusia (OR 9.3; CI 5.36-16.12) were strongly associated with COVID-19. High-risk exposure (OR 12.20; CI 6.80-21.90), especially in the same household (OR 4.14; CI 1.28-13.33), was also correlated; the more household members, especially with flu-like symptoms, the higher the risk of COVID-19. Working in an essential workplace was also associated with COVID-19 (OR 2.35; CI 1.40-3.96), whereas smoking was inversely correlated (OR 0.19; CI 0.08-0.44). A model that considered risk factors like anosmia, ageusia, concomitant of symptomatic household members and smoking well discriminated COVID-19 patients from other patients with flu-like symptoms (AUROC 0.84). CONCLUSIONS We report a set of four readily available clinical parameters that allow the identification of high-risk individuals of COVID-19. Our study will not replace molecular testing but will help guide containment efforts while waiting for test results.

Outbreak of Pseudomonas aeruginosa infections after CT-guided spinal injections. J Hosp Infect 2021; 116:1-9. [PMID: 34298033 DOI: 10.1016/j.jhin.2021.07.004] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/17/2021] [Revised: 07/06/2021] [Accepted: 07/07/2021] [Indexed: 11/27/2022]
Abstract
BACKGROUND Meningitis and spinal infections with Gram-negative bacteria after local injections for treatment of chronic back pain are rare. This study investigated an outbreak of Pseudomonas aeruginosa infections following computed tomography (CT)-guided spinal injections (SI). METHODS A case was defined as a spinal infection or meningitis with P. aeruginosa after SI between 10th January and 1st March 2019 in the same outpatient clinic. Patients without microbiological evidence of P. aeruginosa but with a favourable response to antimicrobial therapy active against P. aeruginosa were defined as probable cases. FINDINGS Twenty-eight of 297 patients receiving CT-guided SI during the study period developed meningitis or spinal infections. Medical records were available for 19 patients. In 15 patients, there was microbiological evidence of P. aeruginosa, and four patients were defined as probable cases. Two of 19 patients developed meningitis, while the remaining 17 patients developed spinal infections. The median time from SI to hospital admission was 8 days (interquartile range 2-23 days). Patients mainly presented with back pain (N=18; 95%), and rarely developed fever (N=3; 16%). Most patients required surgery (N=16; 84%). Seven patients (37%) relapsed and one patient died. Although the source of infection was not identified microbiologically, documented failures in asepsis when performing SI probably contributed to these infections. CONCLUSIONS SI is generally considered safe, but non-adherence to asepsis can lead to deleterious effects. Spinal infections caused by P. aeruginosa are difficult to treat and have a high relapse rate.

Abstract
Understanding antibody-based SARS-CoV-2 immunity is critical for overcoming the COVID-19 pandemic and informing vaccination strategies. We evaluated SARS-CoV-2 antibody dynamics over 10 months in 963 individuals who predominantly experienced mild COVID-19. Investigating 2,146 samples, we initially detected SARS-CoV-2 antibodies in 94.4% of individuals, with 82% and 79% exhibiting serum and IgG neutralization, respectively. Approximately 3% of individuals demonstrated exceptional SARS-CoV-2 neutralization, with these “elite neutralizers” also possessing SARS-CoV-1 cross-neutralizing IgG. Multivariate statistical modeling revealed age, symptomatic infection, disease severity, and gender as key factors predicting SARS-CoV-2-neutralizing activity. A loss of reactivity to the virus spike protein was observed in 13% of individuals 10 months after infection. Neutralizing activity had half-lives of 14.7 weeks in serum versus 31.4 weeks in purified IgG, indicating a rather long-term IgG antibody response. Our results demonstrate a broad spectrum in the initial SARS-CoV-2-neutralizing antibody response, with sustained antibodies in most individuals for 10 months after mild COVID-19.

Abstract
OBJECTIVES Multi-system inflammatory syndrome in children (MIS-C) is a post-viral inflammatory vasculopathy of children and adolescents following Covid-19 infection. Since the incidence of SARS-CoV-infections has been increasing in Germany since October 2020, we observe an increasing number of children presenting with MIS-C. DESIGN We present detailed clinical characteristics of a cohort of nine children with MIS-C admitted to a tertiary PICU at the University Hospital of Cologne between March 2020 and February 2021. RESULTS The clinical sings and symptoms are largely in line with recent reports. All but one patient had positive SARS-CoV-2 antibodies. Latency form infection to MIS-C was 4-6 weeks. Two children presented with unusual findings: A girl had encephalomyelitis and a boy developed MIS-C side to side with acute leukemia. CONCLUSION MIS-C has been increasing in Germany paralell to SARS-CoV-2 infections. Rarely, unuasual findings may be associated with MIS-C.

Clinical Impact of Rapid Species Identification From Positive Blood Cultures With Same-day Phenotypic Antimicrobial Susceptibility Testing on the Management and Outcome of Bloodstream Infections. Clin Infect Dis 2021; 70:1285-1293.

Abstract
BACKGROUND Timely availability of microbiological results from positive blood cultures is essential to enable early pathogen-directed therapy. The Accelerate Pheno system (ADX) is a novel technology using fluorescence in situ hybridization for rapid species identification (ID) and morphokinetic bacterial analysis for phenotypic antimicrobial susceptibility testing (AST), with promising results. Yet the impact of this technology on clinical management and patient outcome remains unclear. METHODS We conducted a quasiexperimental before-and-after observational study and analyzed 3 groups with different diagnostic and therapeutic pathways following recent integration of ADX: conventional microbiological diagnostics with and without antimicrobial stewardship program (ASP) intervention, and rapid diagnostics (ADX in addition to conventional standard) with ASP intervention. Primary endpoints were time to adequate, to optimal and to step-down antimicrobial therapy. Secondary endpoints were antimicrobial consumption, in-hospital mortality, length of stay (LOS), and the incidence of Clostridioidesdifficile infection (CDI). RESULTS Two hundred four patients (conventional diagnostics, n = 64; conventional diagnostics + ASP, n = 68; rapid diagnostics + ASP; n = 72) were evaluated. The use of ADX significantly decreased time from Gram stain to ID (median, 23 vs 2.2 hours, P < .001) and AST (median, 23 vs 7.4 hours, P < .001), from Gram stain to optimal therapy (median, 11 vs 7 hours, P = .024) and to step-down antimicrobial therapy (median, 27.8 vs 12 hours, P = .019). However, groups did not differ in antimicrobial consumption, duration of antimicrobial therapy, mortality, LOS, or incidence of CDI. CONCLUSIONS Use of ADX significantly reduced time to ID and AST as well as time to optimal antimicrobial therapy but did not affect antimicrobial consumption and clinical outcome.

Abstract
PURPOSE The incidence of bone and joint infections is increasing while their treatment remains a challenge. Although guidelines and recommendations exist, evidence is often lacking and treatment complicated by complex clinical presentations and therapeutic options. Interdisciplinary boards shown to improve management of other diseases, seem potentially helpful. We describe the establishment of an osteomyelitis board to show the existing demand for such a platform. METHODS All patients discussed in the board for bone and joint infections between October 2014 and September 2020 were included in this retrospective study. Data were extracted from patient records and analyzed descriptively. RESULTS A total of 851 requests related to 563 patients were discussed in the board during the study period. After a run-in period of 3 years, a stable number of cases (> 170/year) were discussed, submitted by nearly all hospital departments (22 of 25). Recommendations were mainly related to antibiotic treatment (43%) and to diagnostics (24%). Periprosthetic joint infections were the most frequent entity (33%), followed by native vertebral osteomyelitis and other osteomyelitis. In 3% of requests, suspected infection could be excluded, in 7% further diagnostics were recommended to confirm or rule out infection. CONCLUSIONS A multidisciplinary board for bone and joint infections was successfully established, potentially serving as a template for further boards. Recommendations were mainly related to antibiotic treatment and further diagnostics, highlighting the need for interdisciplinary discussion to individualize and optimize treatment plans based on guidelines. Further research in needed to evaluate impact on morbidity, mortality and costs.

Abstract
BACKGROUND With 1.5 million deaths worldwide in 2018, tuberculosis (TB) remains a major global public health problem. While pulmonary TB (PTB) is the most common manifestation, the proportion of extrapulmonary TB (EPTB) is increasing in low-burden countries. EPTB is a heterogeneous disease entity posing diagnostic and management challenges due to the lack of reliable biomarkers. In this study, we prospectively evaluated clinical data and treatment response which were correlated with different biomarkers. METHODS The study was conducted at the University Hospital of Cologne. 20 patients with EPTB were enrolled. We analyzed plasma interferon-γ-inducible protein 10 (IP-10) levels in plasma by ELISA for up to 12 months of treatment. In addition, the QuantiFERON®-TB Gold Plus (QFT® Plus) test was performed during the course of treatment. Clinical data were assessed prospectively and correlated with QFT® Plus and IP-10 levels. RESULTS Plasma IP-10 levels were found to be significantly increased (p < 0.001) in patients with extensive disease compared to patients with limited disease (cervical lymph node TB) or healthy controls. In patients with clinically confirmed paradoxical reaction (PR), a further increase of IP-10 was noted. IFN-γ measured by the QFT® Plus test did not decrease significantly during the course of treatment. Of note, in four EPTB patients (20%) without radiographic pulmonary involvement, sputum culture was positive for Mycobacterium tuberculosis. CONCLUSION Our data demonstrate that IP-10 may be a valuable biomarker for estimation of disease severity in EPTB and monitoring of the disease course in extensive forms. However, IP-10 may be less suitable for diagnosis and monitoring of EPTB patients with limited disease. The QFT® Plus test does not appear to be a suitable marker for therapy monitoring. Sputum should be examined in EPTB patients even in case of normal diagnostic imaging of the chest.

Abstract
ZusammenfassungWir berichten über einen 90-jährigen Patienten mit Prostata-Karzinom, bei dem initial ein Morbus Grover bestand, welcher einen Wandel der klinischen Morphe hin zu einer erworbenen reaktiv perforierenden Kollagenose im Kontext eines paraneoplastischen Geschehens zeigte. Die detaillierte Pathogenese der transienten akantholytischen Dermatose Grover sowie der reaktiv perforierenden Kollagenose ist derzeit unklar. Während die reaktiv perforierende Kollagenose sporadisch in den paraneoplastischen Kontext gerückt wird, ist der Morbus Grover bisher nicht als paraneoplastische Erscheinung eingeordnet worden. Wir diskutieren die klinischen und histologischen differenzialdiagnostischen Überlegungen und empfehlen auf Basis dieser Beobachtungen bei Auftreten eines auffälligen Morbus Grover an fakultative Paraneoplasien zu denken.

Abstract
Embolic events are associated with increased mortality in patients with infective endocarditis (IE). The goal of this study was to gain experience with the application of contrast-enhanced ultrasound (CEUS) in IE to detect abdominal complications. CEUS was performed in 40 patients from a prospective register of IE. CEUS was able to detect abdominal embolic events or metastatic infection in 12 patients (30%). Most commonly seen were splenic infarctions (n = 10), followed by renal infarction (n = 2), liver abscess (n = 1) and mycotic aneurysm (n = 1). Six out of 14 lesions were only detected by CEUS and not by conventional ultrasound. Abdominal complications revealed by CEUS were associated with a detectable valve vegetation (p = 0.04) and larger vegetation size (p = 0.01). In three patients, a non-IE related abdominal lesion (two hepatocellular carcinomas, one psoas hematoma) was detected. CEUS is a feasible diagnostic method in detection of abdominal complications of IE.

Abstract
OBJECTIVES Non-treponemal serological tests are used to monitor treatment response during syphilis infection. Syphilis- and HIV-coinfected patients may experience incomplete resolution in non-treponemal titres, which is referred to as the serofast state. The goal of this study was to evaluate risk factors for serofast state in HIV-infected patients. METHODS From November 2015 to June 2018, 1530 HIV-positive patients were tested for syphilis using a Treponema pallidum particle agglutination (TPPA) assay. Among TPPA-positive patients, medical records were reviewed for early syphilis infection. Serofast state was defined as a less than four-fold decrease in non-treponemal antibody titres during a 6-month follow-up period in the absence of symptoms of syphilis. Baseline characteristics were tested as predictive factors of serological response. RESULTS In all, 515 patients (33.7%) tested positive in TPPA assays, and in 163 patients at least one previous syphilis infection was documented. A total of 61 out of 163 patients (37.4%) were in a serofast state. A history of previous syphilis infection (61 vs. 43%; P = 0.04) was more common in serofast patients than in patients with serological cure after 6 months. Non-treponemal titres ≥ 1:32 before therapy (47 vs. 25%; P = 0.005) and adjunctive corticosteroids to prevent the Jarisch-Herxheimer reaction (35% vs 15%; P = 0.006) were associated with serological cure after 6 months, but corticosteroid therapy had no influence at 12 months. The intensity of syphilis treatment did not affect serological cure. CONCLUSION Corticosteroids for prevention of the Jarisch-Herxheimer reaction were associated with earlier serological cure. Although serological response is the accredited surrogate method to monitor syphilis treatment, the biological significance of the serofast state remains unclear.
