Abstract
BACKGROUND In 2011-2012, the European Centre for Disease Prevention and Control (ECDC) initiated the first European point prevalence survey (PPS) of healthcare-associated infections (HCAIs) in addition to targeted surveillance of the incidence of specific types of HCAI such as surgical site infections (SSIs). AIM To investigate whether national and multi-country SSI incidence can be estimated from ECDC PPS data. METHODS In all, 159 hospitals were included from 15 countries that participated in both ECDC surveillance modules, aligning surgical procedures in the incidence surveillance to corresponding specialties from the PPS. National daily prevalence of SSIs was simulated from the incidence surveillance data, the Rhame and Sudderth (R&S) formula was used to estimate national and multi-country SSI incidence from the PPS data, and national incidence per specialty was predicted using a linear model including data from the PPS. FINDINGS The simulation of daily SSI prevalence from incidence surveillance of SSIs showed that prevalence fluctuated randomly depending on the day of measurement. The correlation between the national aggregated incidence estimated with R&S formula and observed SSI incidence was low (correlation coefficient = 0.24), but specialty-specific incidence results were more reliable, especially when the number of included patients was large (correlation coefficients ranging from 0.40 to 1.00). The linear prediction model including PPS data had low proportion of explained variance (0.40). CONCLUSION Due to a lack of accuracy, use of PPS data to estimate SSI incidence is recommended only in situations where incidence surveillance of SSIs is not performed, and where sufficiently large samples of PPS data are available.

Abstract
BACKGROUND Surveillance of surgical site infections (SSIs) is a core component of effective infection control practices, though its impact has not been quantified on a large scale. AIM To determine the time-trend of SSI rates in surveillance networks. METHODS SSI surveillance networks provided procedure-specific data on numbers of SSIs and operations, stratified by hospitals' year of participation in the surveillance, to capture length of participation as an exposure. Pooled and procedure-specific random-effects Poisson regression was performed to obtain yearly rate ratios (RRs) with 95% confidence intervals (CIs), and including surveillance network as random intercept. FINDINGS Of 36 invited networks, 17 networks from 15 high-income countries across Asia, Australia and Europe participated in the study. Aggregated data on 17 surgical procedures (cardiovascular, digestive, gynaecological-obstetrical, neurosurgical, and orthopaedic) were collected, resulting in data concerning 5,831,737 operations and 113,166 SSIs. There was a significant decrease in overall SSI rates over surveillance time, resulting in a 35% reduction at the ninth (final) included year of surveillance (RR: 0.65; 95% CI: 0.63-0.67). There were large variations across procedure-specific trends, but strong consistent decreases were observed for colorectal surgery, herniorrhaphy, caesarean section, hip prosthesis, and knee prosthesis. CONCLUSION In this large, international cohort study, pooled SSI rates were associated with a stable and sustainable decrease after joining an SSI surveillance network; a causal relationship is possible, although unproven. There was heterogeneity in procedure-specific trends. These findings support the pivotal role of surveillance in reducing infection rates and call for widespread implementation of hospital-based SSI surveillance in high-income countries.

Abstract
BACKGROUND Various measures are considered to reduce the risk of surgical site infection (SSI), including preoperative decolonization. Details of preoperative decolonization practices in surgical departments have not been investigated in Austria. AIM To analyse the current situation of pre-surgical patient decolonization in national hospitals and to assess the current knowledge on this procedure among surgeons of different surgical disciplines. METHODS A 12-point structured questionnaire was distributed to all Austrian hospitals with at least one surgical department. FINDINGS Two-thirds (103/158; 65%) of responding surgeons stated that any type of preoperative decolonization is implemented in their surgical department. There was heterogeneity of different protocols, ranging from decolonization of only known S. aureus carriers, of a subgroup of patients, or universal decolonization of all patients before elective surgery. Octenidine was the most frequently used antimicrobial compound (60.2%), followed by mupirocin (38.8%), triclosan (14.6%), polyhexanide (12.6%), chlorhexidine (11.7%), and didecyldimonium chloride (7.8%). CONCLUSION Preoperative decolonization seems to be performed in Austrian hospitals on a routine basis. However, this measure is implemented using a variety of modalities, antimicrobial compounds, and staff. Since our survey also demonstrated that those who are better informed about preoperative decolonization are also those who are more convinced of the usefulness of the preventive measure, future activities should not only focus on generating more comparable studies in this field, but should also include targeted education.

Abstract
Surgical implants and other foreign material are increasingly used in modern medicine to restore or to improve the function of the human body. Infection of an implant is associated with considerable morbidity due to frequent hospitalizations, surgery and antimicrobial treatment. The underlying mechanism is the formation of a bacterial biofilm on the surface of the implanted body. The recognition and diagnosis of implant infections is essential for further therapy and, above all, the decision to remove and exchange the implant. Methods We compared the data of 60 patients with implant infections with those of 60 patients with transient bacteremia caused by Staphylococcus epidermidis. The pathogens isolated from blood were characterized with regard to antimicrobial susceptibility and formation of biofilms using a static microtiter plate model. Wild type skin isolates from non-hospitalized healthy volunteers served as control with regard to antimicrobial susceptibility and biofilm formation. Results Clinical signs and symptoms, underlying diseases and outcome were not different in either group. However, patients with implant infection had fever over a longer time (mean 12 days versus 3 days, respectively, p & 0.05) and more often positive blood cultures than patients with transient bacteremia (3.1 versus 1.2, p & 0.05). Thrombocytopenia was observed in patients with implant infections but not in patients with transient bacteremia (p & 0.05). Biofilms were formed in 86.4 % of the isolates in implant infection, in 88.8 % in transient bacteremia and in 76.9 % of the isolates from healthy volunteers (not significant). Multi-resistance to penicillin, oxacillin, erythromycin, clindamycin, ciprofloxacin and trimethoprim was more common in the hospital strains than in the wild type strains (75.6 % versus 48.7 %, p & 0.05). Conclusions The clinical features of implant infections are indistinguishable from those of transient bacteremia. Persisting fever and multiple blood culture yielding the growth of skin flora bacteria are strong indicators for infection of implanted material. Biofilm formation and antimicrobial multiresistance, as common in implant infection as in transient bacteremia, seem to be accessory factors in infections due to Staphylococcus epidermidis.

Abstract
Research on implant infections requires cooperative efforts and integration between basic and clinical expertises. An international group of women scientists is acting together in this field. The main research topics of the participants of this group are described. Formation of bacterial biofilms, antibiotic resistance and production of virulence factors like adhesins and toxins are investigated. New biomaterials, coatings and drugs designed to inhibit microbial adhesion are evaluated, and infection-resistant biomaterials are under study, such as a novel heparinizable polycarbonate-urethane (Bionate) or incorporation of diamino-diamide-diol (PIME) to reduce bacterial attachment. The correlation between biofilm production and the accessory-gene-regulator (agr) is investigated in Staphylococcus aureus. The ability to form biofilm has also been shown to be one of the important virulence factors of Enterococcus faecalis, favouring colonization of inert and biological surfaces. The study of quorum sensing has led to the discovery of a quorum sensing inhibitor termed RIP that suppresses staphylococcal biofilm and infections. The immune response and the local defence mechanisms of the host against implant-associated infections, activation and infiltration of immunocompetent cells into the sites of infection have been studied in patients with implant-associated osteomyelitis. Production of monoclonal antibodies (mAbs) as possible vaccines against the staphylococcal collagen-binding MSCRAMMs is in progress. (Int J Artif Organs 2008; 31: 858–64)

Abstract
Background Endocarditis, and prosthetic valve endocarditis in particular, is a serious disease with high morbidity and mortality. We investigate the effects of tigecycline, linezolid and vancomycin on biofilms of viridans group streptococci (VGS) isolated from patients with definite native or prosthetic valve endocarditis. Methods and Results Ten of 20 VGS blood stream isolates from patients with endocarditis formed biofilms in the microtiter plate biofilm model. The minimal inhibitory concentrations (MIC) for tigecycline, linezolid and vancomycin were determined using the microdilution broth method. Biofilms were grown for 24 hours and were incubated with tigecycline, linezolid and vancomycin at increasing concentrations from 1-128x MIC of the isolate being tested. Biofilm thickness was quantified by measuring the optical density (OD) after dyeing it with crystal violet. The incubation of the biofilms with tigecycline, linezolid or vancomycin resulted in a significant reduction of OD compared to the control biofilm without antibiotic (p<0.05). The optical density ratio (Odr) decreased significantly at 2x MIC for tigecycline, and at 8x MIC for linezolid and vancomycin (p<0.05). Although biofilms persisted even at the highest antibiotic concentrations of 128x MIC, bacterial growth was eradicated starting at concentrations of 16x MIC for vancomycin and of 32x MIC for linezolid, but not for tigecycline, up to a concentration of 128x MIC. Conclusions In the present study on viridans streptococci isolated from patients with endocarditis, tigecycline and linezolid reduced the density of the biofilms as effectively as vancomycin. However, linezolid and vancomycin were bactericidal at higher concentrations. Linezolid and vancomycin at very high doses may be useful in the treatment of biofilm-associated diseases caused by VGS infections.

Abstract
Introduction In the time of increasing resistance and paucity of new drug development there is a growing need for strategies to enhance rational use of antibiotics in German and Austrian hospitals. An evidence-based guideline on recommendations for implementation of antibiotic stewardship (ABS) programmes was developed by the German Society for Infectious Diseases in association with the following societies, associations and institutions: German Society of Hospital Pharmacists, German Society for Hygiene and Microbiology, Paul Ehrlich Society for Chemotherapy, The Austrian Association of Hospital Pharmacists, Austrian Society for Infectious Diseases and Tropical Medicine, Austrian Society for Antimicrobial Chemotherapy, Robert Koch Institute. Materials and methods A structured literature research was performed in the databases EMBASE, BIOSIS, MEDLINE and The Cochrane Library from January 2006 to November 2010 with an update to April 2012 (MEDLINE and The Cochrane Library). The grading of recommendations in relation to their evidence is according to the AWMF Guidance Manual and Rules for Guideline Development. Conclusion The guideline provides the grounds for rational use of antibiotics in hospital to counteract antimicrobial resistance and to improve the quality of care of patients with infections by maximising clinical outcomes while minimising toxicity. Requirements for a successful implementation of ABS programmes as well as core and supplemental ABS strategies are outlined. The German version of the guideline was published by the German Association of the Scientific Medical Societies (AWMF) in December 2013.

Abstract
The aim of this study was to evaluate whether coating titanium discs with selenium in the form of sodium selenite decreased bacterial adhesion of Staphylococcus aureus and Staph. epidermidis and impeded osteoblastic cell growth. In order to evaluate bacterial adhesion, sterile titanium discs were coated with increasing concentrations of selenium and incubated with bacterial solutions of Staph. aureus (ATCC 29213) and Staph. epidermidis (DSM 3269) and stained with Safranin-O. The effect of selenium on osteoblastic cell growth was also observed. The adherence of MG-63 cells on the coated discs was detected by staining with Safranin-O. The proportion of covered area was calculated with imaging software. The tested Staph. aureus strain showed a significantly reduced attachment on titanium discs with 0.5% (p = 0.011) and 0.2% (p = 0.02) selenium coating. Our test strain from Staph. epidermidis showed a highly significant reduction in bacterial adherence on discs coated with 0.5% (p = 0.0099) and 0.2% (p = 0.002) selenium solution. There was no inhibitory effect of the selenium coating on the osteoblastic cell growth. Selenium coating is a promising method to reduce bacterial attachment on prosthetic material.

Abstract
The aim of this study was to compare the quantitative susceptibility of methicillin-resistant and -susceptible Staphylococcus aureus (MRSA and MSSA) strains from three European countries to nine antistaphylococcal agents. The antibiotic susceptibility of 274 MRSA and 284 MSSA strains from Hungary, Austria and macedonia was tested by the broth microdilution method. The clonal relationship of strains was determined by pulsed-field gel electrophoresis. Intermediate susceptibility to vancomycin appeared in Macedonian MRSA strains. Macedonian MRSA strains had high-level amikacin and gentamicin resistance. MSSA strains generally were susceptible to all drugs at minimum inhibitory concentrations (MIC(50)) except for gentamicin resistance in Macedonian strains. In Hungary and Austria a common antibiotic resistance phenotype of MRSA predominated, while in macedonia three other phenotypes were also prevalent. Geographical differences in the resistance of S. aureus are still high. Since resistance levels of MRSA and MSSA strains differ extensively, they should be considered separately for antibiotic resistance analysis.

Abstract
More detailed information on Candida colonisation and infection of the mucous membranes in organ transplant recipients (OTR) is of particular interest. Therefore, this issue was prospectively evaluated in 400 different OTR in different posttransplantation periods as well as in 405 healthy age- and sex-matched controls. In addition, possible risk factors and the clinical condition in the OTR were evaluated. Independent of the transplanted organ there is a statistically significant decrease in the number of positive culture results, of symptomatic candidiasis and an increase of isolated non-albicans Candida species corresponding to length of the posttransplantation period. No significant differences could be observed in the OTR in association with different immunosuppressive regimen; however, higher dosages of corticosteroids and tacrolimus correlated with symptomatic candidiasis. As Candida spp. may also cause systemic infection and dissemination, additional knowledge about cofactors and associated strains may have an impact on therapeutic decisions.

Abstract
A retrospective survey of candidaemia between 2001 and 2006 was performed at the University Hospital of Vienna, a 2200-bed centre with large organ transplantation and haematology-oncology units. The incidence rate of Candida spp. in blood cultures increased from 0.27 cases/1000 admissions in 2001 to 0.77 cases/1000 admissions in 2006 (p <0.005). The incidence of candidaemia caused by Candida albicans and by non-albicans Candida spp. both increased during this period; although there was a trend towards an increased incidence (37%) of non-albicans Candida spp., particularly Candida glabrata, in surgical wards, C. albicans remained the predominant pathogen (63%). In the haematology-oncology unit, C. albicans remained the leading pathogen (23/29 isolates, 79%), followed by Candida tropicalis and C. glabrata (2/29, 7% each), Candida sake and Candida lusitaniae (1/29, 3% each). The overall survival rate was 43.8%, ranging from 32.8% in 2004 to 63.6% in 2002. In total, 108 (33.2%) patients died within 4 weeks of the first isolation of Candida spp. from blood; 58 (54%) of these patients died within the first 7 days, and a further 34 patients died within the next 3 months. Fluconazole was used extensively (24 701.5 defined daily doses), followed by amphotericin B (8981.4 defined daily doses), during 2005. The consumption of antifungal agents increased continuously (p <0.05) because of increased use of voriconazole and caspofungin. Although the numbers of susceptible patients remained unchanged, the net increase in the number of cases of candidaemia warrants a re-evaluation of the risk-factors and the use of improved diagnostic procedures for invasive fungal infections.

Abstract
BACKGROUND Invasive fungal infections are often diagnosed by histopathology without identification of the causative fungi, which show significantly different antifungal susceptibilities. AIMS To establish and evaluate a system of two seminested polymerase chain reaction (PCR) assays to identify and discriminate between agents of aspergillosis and mucormycosis in paraffin wax embedded tissue samples. METHODS DNA of 52 blinded samples from five different centres was extracted and used as a template in two PCR assays targeting the mitochondrial aspergillosis DNA and the 18S ribosomal DNA of zygomycetes. RESULTS Specific fungal DNA was identified in 27 of 44 samples in accordance with a histopathological diagnosis of zygomycosis or aspergillosis, respectively. Aspergillus fumigatus DNA was amplified from one specimen of zygomycosis (diagnosed by histopathology). In four of 16 PCR negative samples no human DNA was amplified, possibly as a result of the destruction of DNA before paraffin wax embedding. In addition, eight samples from clinically suspected fungal infections (without histopathological proof) were examined. The two PCR assays detected a concomitant infection with Absidia corymbifera and A fumigatus in one, and infections with Rhizopus arrhizus and A fumigatus in another two cases. CONCLUSIONS The two seminested PCR assays described here can support a histopathological diagnosis of mucormycosis or aspergillosis, and can identify the infective agent, thereby optimising antifungal treatment.

Abstract
Acute HIV-infection mostly presents with unspecifc symptoms. Thus the acute retroviral syndrome is often not readily recognized. Here we present an interim analysis of a prospective study from 62 patients with documented acute HIV infection acquired between January 2002-August 2004 in the greater Zurich area. 61.5% of patients were infected by homosexual contacts, mostly with HIV-1 subtype B, 34% acquired infection by heterosexual contacts, often with non-B-virus subtypes. Transmission occurred in all sexually active age groups (18-72 years). Clinical symptoms presented as follows: fever (77%), pharyngitis (56%), fatigue (52%), gastrointestinal symptoms (45%), rash (39%). On first physician contact, an ARS was only suspected in 27% of the cases. Patients primarily called on their family doctors (37.5%), went to see larger walk in clinics or emergency rooms (37.5%), and 16% were hospitalised. In 16% of patients other sexually transmitted diseases were diagnosed contemporaneously. Drug resistant virus (single class resistance) was transmitted in only one patient.

Abstract
OBJECTIVES Viridans group streptococci (VGS) are a frequent cause of bacterial endocarditis or sepsis in patients with neutropenia. Endocarditis in particular, is associated with plaque formation on the endocardium and valve leaflets whereas VGS septicaemia in neutropenic patients is caused by the influx of oral flora bacteria through mucositic lesions. This study examined the in vitro potency for biofilm formation of clinical VGS bloodstream isolates, and the effects of antibiotics on these biofilms. METHODS During the years 1998-2000, 40 VGS bloodstream isolates from 18 patients with endocarditis and 22 patients with severe sepsis and neutropenia were collected. The MICs of penicillin, teicoplanin and moxifloxacin were determined using the microdilution broth method according to NCCLS criteria. Biofilms were grown in microtitre plates, dyed with Crystal Violet, and the mean optical density (OD) was used for quantification. Biofilms were incubated with penicillin, teicoplanin and moxifloxacin at various concentrations starting with the MICs for the respective isolates tested. RESULTS Isolates from eight out of 18 patients with endocarditis and six out of 22 patients with neutropenia formed biofilms (not significant). For the 14 isolates, the MIC(90)s (range) of penicillin, teicoplanin and moxifloxacin were 0.5 mg/L (0.001-0.5), 0.125 mg/L (0.025-0.125) and 0.5 mg/L (0.05-0.5), respectively. Generally, biofilms persisted although incubated with the antibiotics up to concentrations of 128 x MIC. However, the ODs of biofilms after incubation with an antibiotic were significantly lower than the ODs of biofilms without antibiotic (P<0.05). A significant decrease in the biofilms with increasing antibiotic concentrations was observed for teicoplanin and moxifloxacin, but not for penicillin G. CONCLUSIONS VGS isolated from patients with endocarditis and patients with sepsis and neutropenia form biofilms. Biofilms persist even when exposed to antibiotics at concentrations up to 128 x MIC. Nevertheless, teicoplanin and moxifloxacin reduced the density of the biofilms at concentrations >/=16 x MIC. Thus, testing the effects of antibiotics on biofilms may supply useful information in addition to standard in vitro testing, particularly in diseases where biofilm formation is involved in the pathogenesis.

Abstract
A young man who ate large quantities of probiotic yogurt developed endocarditis and septic arthritis caused by Lactobacillus rhamnosus. The pathogenic isolate could not be distinguished from the yogurt microflora using methods routinely used in the clinical microbiology laboratory. Only by using more appropriate methodology, including PCR, the pathogen could be distinguished from the yogurt isolate.

Abstract
BACKGROUND Streptococcal subacute endocarditis is characterized by low-grade systemic inflammation. Although structural cardiac defects are pivotal, phagocytic cells, i.e. monocytes and neutrophils, are involved in the induction and the course of bacterial endocarditis. Decreased production of reactive oxygen metabolites was described in long-lasting infections. We hypothesized that the oxidative burst of phagocytes induced by the infecting organism is defective in patients with streptococcal endocarditis. PATIENTS AND METHODS The monocytes and neutrophils of 11 patients with streptococcal native valve endocarditis were challenged with the respective pathogens and two control streptococcal strains, and the oxidative burst was determined by fluorescence-activated cell sorter analysis. These experiments were done before any antibiotic therapy was administered, and repeated at least 12 months after recovery. Eight volunteers served as healthy controls. RESULTS The monocyte response to the respective pathogens was decreased in the patient groups compared to the response to the control streptococci. After cure the monocyte response to the pathogens was not different to the response to the control strains. The monocyte response of the healthy volunteers did not show any differences between the patients' pathogens and the control strains. The neutrophil oxidative burst to the pathogens was similar to that to the control streptococci in both patient and the volunteer group. CONCLUSION The decreased response of patient monocytes to the pathogens may contribute to the low-grade inflammatory response and to the course of streptococcal endocarditis.

Abstract
The objectives of this study were to evaluate the reliability of herpes simplex virus (HSV) PCR testing in cerebrospinal fluid (CSF) for the detection of herpes simplex encephalitis. This was done by examining retrospectively the clinical follow-up of a large group of patients tested routinely by HSV-PCR. In addition, an attempt was made to assess the incidence of herpes simplex encephalitis in a central European population. CSF samples from 1,427 patients from all Vienna hospitals were submitted for HSV-PCR testing during a period of 4 years and 8 months. Herpes simplex encephalitis was detected by PCR in 12 cases and by serological methods in one additional patient. Retrospective analysis of the course of disease, which was possible in 799 PCR-negative patients, led to the identification of three additional cases in which herpes simplex encephalitis appears to have occurred despite negative PCR results. Failure of the PCR in these patients is most likely due to the time of obtaining CSF during the course of disease. A high specificity of the assay was demonstrated by the lack of false positive results in any of the 708 cases in which other causes for the neurological symptoms had been identified in the follow-up. The incidence of herpes simplex encephalitis in the population of Vienna was between 1 case/469,000-577,000 individuals/year. The highest annual incidence was detected in the age group between 3 months and 3 years, which, however, could not be confirmed statistically.

Abstract
Susceptibility testing of fungi by flow cytometry (also called fluorescence-activated cell sorting [FACS]) using vital staining with FUN-1 showed a good correlation with the standard M27-A procedure for assessing MICs. In this study we determined MICs for blood culture isolates from patients with candidemia by NCCLS M27-A and FACS methods and correlated the clinical outcome of these patients with in vitro antifungal resistance test results. A total of 24 patients with candidemia for whom one or more blood cultures were positive for a Candida sp. were included. Susceptibility testing was performed by NCCLS M27-A and FACS methods. The correlation of MICs (NCCLS M27-A and FACS) and clinical outcome was calculated. In 83% of the cases, the MICs of fluconazole determined by FACS were within 1 dilution of the MICs determined by the NCCLS M27-A method. For proposed susceptibility breakpoints, there was 100% agreement between the M27-A and FACS methods. In the FACS assay, a fluconazole MIC of <1 microg/ml was associated with cure (P < 0.001) whereas an MIC of > or =1 microg/ml was associated with death (P < 0.001). The M27-A-derived fluconazole MICs did not correlate with outcome (P = 1 and P = 0.133).

Abstract
In order to determine the comparative efficacy of vancomycin, teicoplanin, levofloxacin, moxifloxacin, and linezolid against methicillin- and ciprofloxacin-resistant Staphylococcus aureus, each agent was tested against 65 genetically different strains using the microbroth dilution method. All of the isolates were typed using the enterobacterial repetitive intergenic consensus polymerase chain reaction to exclude multiple isolates of epidemic clones. Susceptibility testing revealed that all of the isolates were susceptible to vancomycin and teicoplanin. Linezolid exhibited minimum inhibitory concentration (MIC) levels ranging from 1 to 4 mg/l (MIC90, 4 mg/l). The MICs of moxifloxacin and levofloxacin ranged from 0.01 to 8 mg/l (MIC90, 8 mg/l) and 0.25 to 32 mg/l (MIC90. 16 mg/l), respectively. Thus, linezolid is active against methicillin- and ciprofloxacin-resistant Staphylococcus aureus, whereas moxifloxacin may need to be administered at a dose higher than recommended in order to successfully treat serious infections.

BACKGROUND Laminin, a major component of the basement membrane, plays a critical role in normal cell adhesion and also during tissue invasion of pathogenic microorganisms. MATERIALS AND METHODS Serum laminin concentrations were determined in 19 patients with Candida albicans sepsis, in 13 patients with bacterial sepsis and in 20 noninfectious controls. RESULTS Serum laminin concentrations of both, patients with candidal and bacterial sepsis, were significantly elevated compared to the controls (486 ng mL-1 [155-924], median [range]; P < 0.01). Laminin concentrations were significantly higher in patients with Candida sepsis than in patients with bacterial sepsis on day 1 (2565 ng mL-1 [659-6064] vs. 994 ng mL-1 [386-2064]; P < 0.01), day 7 (1594 ng mL-1 [607-4611] vs. 684 ng mL-1 [284-1920]; P < 0.05) and day 14 (1444 ng mL-1 [202-2131] vs. 386 ng mL-1 [180-1658]; P < 0.05). CONCLUSIONS Laminin serum concentrations might be useful to differentiate nonbacterial, bacterial and fungal etiology.

Abstract
Partial fungal obstruction of the renal collecting system is an unusual finding among infants that poses specific management problems. We report a patient with sepsis and fungal infection of the kidneys post surgery who presented with bilateral fungus balls and was successfully managed by conservative measures. Sonography is the imaging technique of choice in the diagnosis and follow-up of such patients. The need for prompt diagnosis in high-risk patients and the role of sonography are discussed.

Abstract
Cytokines, such as tumor necrosis factor-alpha (TNF-alpha), interleukin-6 (IL-6) and tumor necrosis factor-soluble receptor (TNF-sR), and adhesion molecules, e.g. vascular adhesion molecule-1 (VCAM-1) and E-selectin, play an important role in the pathogenesis of bacterial sepsis. Experimental data on cytokine expression during candidaemia are controversial. In this study, plasma concentrations of cytokines and adhesion molecules were compared between patients with sepsis due to Candida albicans and bacterial sepsis. Plasma levels of TNF-alpha, TNF-sR, IL-6, VCAM-1 and E-selectin, were determined in 20 patients with sepsis due to C. albicans, in 20 patients with bacterial sepsis, and in 20 controls on days 1, 7 and 14. On day 1, elevated plasma levels of TNF-alpha, TNF-sR and IL-6 were detected in both sepsis groups compared to controls. On day 1, VCAM-1 levels were higher, and E-selectin levels were lower in patients with Candida sepsis than in patients with bacterial sepsis (p < 0.05). At any time, VCAM-1 levels were significantly greater in patients with Candida sepsis than in patients with bacterial sepsis (p < 0.05). Non-survivors, regardless of the etiology of sepsis, had higher blood levels of IL-6, TNF-sR and E-selectin than survivors. The cytokines, TNF-alpha, IL-6 and TNF-sR, and the adhesion molecules, VCAM-1 and E-selectin, are involved in sepsis due to C. albicans as in bacterial sepsis.

Abstract
In a 3-month prospective study among 203 Austrian outpatients with diarrhea, the role of pathogenic Escherichia coli and the use of the polymerase chain reaction in screening Escherichia coli isolates from clinical stool specimens were evaluated. Enteroaggregative Escherichia coli and enterotoxigenic Escherichia coli combined were identified as the second most frequent cause of diarrhea. Of a total of 85 bacterial pathogens isolated from 80 patients, 15 were pathogenic Escherichia coli, 13 enteroaggregative Escherichia coli and two enterotoxigenic Escherichia coli. Enteropathogenic, enteroinvasive, and enterohemorrhagic Escherichia coli isolates were not detected.

Abstract
The incidence of systemic fungal infection has been increasing during the last two decades. Candida and Aspergillus spp. are the classical opportunistic pathogens. Rare fungi, such as Mucor, Rhizopus, Fusarium, Trichosporon, Paecilomyces, Alternaria, Cladosporium and Pseudoallescheria, are emerging as cause of systemic fungal infection in the immunocompromised host. For more than 40 years Amphotericin B has been the gold standard of antifungal treatment because of its broad spectrum comprising yeasts, dimorphic fungi and moulds. Its nephrotoxicity has led to the development of lipid-associated preparations of amphotericin B: liposomal amphotericin B, amphotericin B colloidal dispersion and amphotericin B lipid complex. These preparations are less nephrotoxic, but higher doses than those of conventional amphotericin B are needed to achieve the same effect. The triazole fluconazole is the treatment of choice in infections caused by Candida albicans. New antifungal compounds are voriconazole and the candins, the pradimicin/benanomycin family, nikkomycin Z and a liposomal preparation of nystatin.

Abstract
The role of Helicobacter pylori urease in opsonization by human complement was investigated. H. pylori wild type strain N6 and isogenic mutants lacking either the large urease subunit (UreB) or an accessory urease protein (UreG) were incubated with different sera. C3b bound to the bacteria was measured by specific staining and flow cytometry. As compared with opsonization of N6 and the UreG-lacking mutant, opsonization of the UreB-lacking mutant was significantly increased after incubation with sera from both H. pylori uninfected (P<.001) or infected (P<.05) persons. However, when sera from uninfected persons were used, effective opsonization of this mutant proved to be dependent mainly on the classical pathway of complement activation. Irrespective of the serum used, opsonization values were very low after selective inactivation of the classical or the alternative pathway. Reduced opsonization of the urease-expressing strains could, to some extent, result from degradation of bound C3b.

Abstract
We provide evidence that the commercially available preparations of glycopeptides for intravenous application are well tolerated by endothelial cells when applied in concentrations less than 5 mg/ml. Since the antibiotics tested are administered at maximal concentrations of 10 mg/ml, the dose range used in our in vitro experiments (5 and 10 mg/ml) mimics possible clinical concentrations at the site of infusion. Similar concentrations may be reached by retrograde intravenous pressure infusion techniques (10-12). We have demonstrated that these high concentrations lead to considerable endothelial cell damage. These findings may explain the common side effect associated with intravenously applied glycopeptides namely pain and phlebitis at the site of infusion (2, 13). Figure 1 shows that a detrimental effect measurable after 20 min occurs only using vancomycin solutions at concentrations of 10 mg/ml, whereas already a dilution to 5 mg/ml renders the solutions more compatible to HUVEC. These data are in line with the observation that slow intravenous application of glycopeptides into large veins can largely prevent the occurrence of local phlebitis. Alternatively, the occurrence of phlebitis should be avoidable by diluting the manufacturers' preparations at least to 2-5 mg/ml and not 10 mg/ml as recommended by the manufacturer of vancomycin. The same aspects need to be considered for use of glycopeptides for retrograde high pressure infusion. The tolerance of intravenously applied antibiotics has previously been tested in animal models (4). Our model of human venous endothelial cells for testing antibiotic solutions for intravenous compatibility provides a valuable alternate model. In conclusion our data show that the commercial preparation of teicoplanin is more compatible for HUVEC than those of vancomycin.

Abstract
Patients with serious staphylococcal infections, e.g. endocarditis and osteomyelitis, need prompt and prolonged parenteral antibiotic treatment to ensure eradication of the causative pathogen. The major cost in the treatment of these infections is the long period of hospitalisation required for the administration of intravenous antibiotics. To shorten the hospitalisation period, outpatient treatment can be given to some patients. In this study, patients with acute exacerbations of chronic osteomyelitis (n = 44) or endocarditis (n = 10) were treated with intravenous teicoplanin. The pathogens were Staphylococcus aureus (n = 41, 13 of which were methicillin resistant) and coagulase-negative staphylococci (n = 13, one of which was methicillin resistant). After a mean loading dose of 15 mg/kg for 3 to 10 days, patients received teicoplanin 3 times a week at a dose (mean 15 mg/kg) individualised to achieve serum trough concentrations of approximately 10 mg/L for osteomyelitis and 20 mg/L for endocarditis. Treatment duration ranged from 28 to 150 (mean 62) days for patients with osteomyelitis and from 28 to 88 (mean 49) days for patients with endocarditis. 37 (84%) patients with osteomyelitis and 8 (80%) patients with endocarditis were treated successfully. Adverse events were observed in 9 patients and included rash (n = 3), thrombocytopenia (n = 3), and drug fever, pseudomembranous colitis, nausea, leucopenia and transient hearing impairment (one patient each). In conclusion, this study demonstrates that teicoplanin can be administered successfully in an outpatient setting according to a 3-times weekly schedule for the treatment of patients with staphylococcal osteomyelitis and endocarditis.

Abstract
The use of human venous endothelial cells for testing antibiotic solutions for intravenous compatibility provides a valuable alternative to animal models. In order to evaluate the effect of vancomycin and teicoplanin on the viability of human umbilical venous endothelial cells, intracellular ATP levels were measured by a luciferin-luciferase assay. Prostacyclin (PGI2) and thromboxane A2 (TXA2) were determined by direct radioimmunoassay. Vancomycin at concentrations of 5 and 10 mg/mL reduced the intracellular ATP content by 18.7% and 69.9%, respectively, within 60 min. In contrast, cellular energy charge remained significantly higher after incubation with teicoplanin at 5 and 10 mg/mL (reduction 8.7% and 15.5%, respectively). Neither vancomycin nor teicoplanin at a concentration of 2 mg/mL led to significant ATP decline. However, endothelial cells incubated with vancomycin resulted in significantly lower release of PGI2 and TXA2 compared with teicoplanin. These results show that teicoplanin is more compatible with endothelial cells than vancomycin, and that both antibiotics are well tolerated if diluted to a final concentration of 2 mg/mL.

Abstract
A prospective, randomized trial was conducted in a medical intensive care unit to assess safety and tolerability of four different dose regimens of intravenous netilmicin given once daily in the treatment of febrile episodes in critically ill patients. Eighty patients with febrile episodes during their stay in the intensive care unit were included in the study. The patients were randomized into four groups: Group 1 received a single daily dose of netilmicin based upon weight, age and renal function according to a dosage nomogram [13] (mean dose 298 +/- 29 mg, median 300 mg, range 250-350 mg), group 2 received 150% of this standard dose (mean 418 +/- 45 mg, median 400 mg, range 350-500 mg), group 3 200% (mean 525 +/- 41 mg, median 500 mg, range 400-550 mg) and group 4 250% (mean 710 +/- 39 mg, median 650 mg, range 600-750 mg). Duration of treatment was six days. Positive cultures were obtained in 29 patients. Serum creatinine and creatinine clearance, as well as netilmicin trough levels and levels of alpha 1-microglobulin showed no significant difference between the groups before, during, and after therapy. Our results indicate that with once daily dosing even high doses of netilmicin are well tolerated in patients with a creatinine clearance of > 70 ml/min before therapy. Necessary precautions include monitoring of drug trough levels (< 1 mg/L) and maintenance of adequate volume status.

Abstract
Thirty-one isolates of Acinetobacter baumannii were collected from ten intensive care units of an Austrian university hospital. All isolates were typed by enterobacterial repetitive intergenic consensus polymerase chain reaction (ERIC-PCR). Two strains colonizing 13 infants in the neonatal intensive care unit were identified by ERIC-PCR. All other Acinetobacter baumannii isolates had highly divergent ERIC-PCR patterns, despite having the same antibiogram. Thus, a hospital-wide clonal distribution, as suggested by identical antibiogram patterns, was excluded by ERIC-PCR.

Abstract
In 35 patients fulfilling the criteria of systemic inflammatory response syndrome (SIRS) of infectious origin, tumor necrosis factor-alpha (TNF-alpha), interleukin-6 (IL-6), tumor necrosis factor-soluble receptor (TNF-sR), and interleukin-12 (IL-12), C-reactive protein (CRP) levels and the Acute Physiology, and Chronic Health Evaluation III score (APACHE III) were determined on days 1 to 7, 14, 21, and 28. The Mortality Probability Models (MPM) II sepsis score was assessed at the time of admission into the study. The MPM II sepsis score correlated with IL-6 plasma levels on day 1. The APACHE III scores correlated with plasma levels of TNF-sR on days 2-7, with IL-6 levels on days 3-7, and with CRP levels on days 4-7 (p < 0.01). The MPM II sepsis score, the APACHE III score, and the IL-6, TNF-sR, and CRP levels were significantly different between survivors and nonsurvivors and between patients with and without shock (p < 0.05). A significant decrease of the APACHE III scores, IL-6, and CRP levels was observed over the study period in the survivor group only (p < 0.05), while neither the dynamics of TNF-alpha nor IL-12 plasma levels contributed to the risk estimation of mortality.

Abstract
This study reports pheno- and genotypical analysis of 9 isolates of vancomycin-resistant enterococci (VRE) and 5 vancomycin-sensitive enterococci (VSE) in Austria: 5 E, faecium isolates of 4 patients (the sole patients demonstrating VRE at the University Hospital of Innsbruck in 1994 and 1995), 3 glycopeptide-sensitive isolates collected in Innsbruck in February 1996 for epidemiological analysis, and 6 enterococcus isolates from the University Hospitals of Vienna and Graz. The pheno- and genotypical analyses of all glycopeptide highly resistant E. faecium and E. faecalis isolates indicated the presence of VanA type resistance. One E. casseliflavus strain with intrinsic VanC-1 resistance showed a characteristic constitutive low-level resistance to vancomycin and susceptibility to teicoplanin. Genotyping with macro-restriction analysis demonstrated that 3 VRE isolates of the 5 E. faecium specimens were identical; the same applied to 2 VSE isolates. The two patients with VRE had been cared for at the same time in a surgical ICU and likewise, the two patients with VSE were simultaneously treated at a neurological ICU. The genotyping of E. faecalis strains showed that two strains of the three VRE isolates exhibited identical patterns. Epidemiological investigation did not reveal a mode of transmission for this cluster. Two of the 8 patients with VRE died within 60 days after isolation of the bacteria; the doctors in charge did not consider that the enterococci had been the cause of death. The results of our study indicate that oral vancomycin administration to humans is a primary cause of VRE in Austrian hospitals. In Austria approximately 66 kg vancomycin, 20% of it given orally, are administered to patients per year. Approx. 18-20 tons Avotan (active ingredient Avoparcin-10%)/year were used in Austria; as of April 1, 1997 the use of this animal foodstuff supplement is prohibited by the European Commission.

Abstract
OBJECTIVE To evaluate the influence of pentoxifylline (PTX), a phosphodiesterase inhibitor, on cytokines and inflammatory proteins in patients suffering from septic shock. DESIGN Prospective study comparing a therapy group to a matched control group. SETTING Medical intensive care unit at a university hospital. PATIENTS Twenty four patients fulfilling the criteria of septic shock were included in this study. Twelve patients received PTX (therapy group) and 12 patients matched for diagnosis, age and gender served as the control group. INTERVENTIONS Pentoxifylline at 1 mg/kg per hour over 24 h in the therapy group. MEASUREMENTS AND RESULTS Cytokine levels [tumor necrosis factor-alpha (TNF)], soluble TNF receptor [TNF-R], and interleukin-6 [IL-6] and inflammatory proteins [C-reactive protein, alpha-1-antitrypsin (AAT), fibronectin, and haptoglobin], as well as hemodynamic parameters and the APACHE III score were evaluated before initiation of therapy and 24 h-later. After 24 h, TNF levels were significantly lower in the therapy group (p = 0.013), while IL-6 levels were significantly higher in the therapy group (p = 0.030). Within the 24 h TNF declined significantly in the therapy group (p = 0.006), while IL-6 showed a significant increase (p = 0.043). AAT and the APACHE III score tended to differ significantly after 24 h between the groups [AAT levels higher in the therapy group (p = 0.05), APACHE III score lower (p = 0.05)]. In the therapy group, the systemic vascular resistance index was significantly higher after 24 h (p = 0.0026) whereas the cardiac index declined (p = 0.035). CONCLUSIONS PTX does influence TNF levels in septic shock patients. Nevertheless, inhibiting a single mediator in severe septic shock cannot stop the inflammatory overreaction.

Abstract
Increased serum sCD14 concentrations are associated with poor outcome in Gram-negative sepsis and trauma patients. In the present study serum sCD14 concentrations were measured in patients with Gram-positive sepsis and compared with Gram-negative septic and nonseptic intensive care unit patients. Furthermore, serum sCD14 concentration was correlated with patient's outcome. Serum samples of 28 Gram-positive (8 nonsurvivors/20 survivors) and 10 Gram-negative bacteriemic patients (3 nonsurvivors/7 survivors) were obtained at the day they met the sepsis criteria defined by Bone et al. (Day 0) and at Days 4 and 7 and compared with 10 nonseptic ICU patients and 10 healthy volunteers. Serum concentrations of sCD14 were measured by ELISA. Significantly higher sCD14 serum concentrations were found on Days 4 and 7 in Gram-positive nonsurvivors than in Gram-positive survivors (Day 4: 5.85 +/- 0.48 vs 4.07 +/- 0.43 microgram/ml, P < 0.05; Day 7: 6.12 +/- 0.46 vs 3.53 +/- 0.33 microgram/ml, P < 0.01). In addition, sCD14 concentrations of Gram-positive nonsurvivors were significantly higher than those of nonseptic ICU patients and healthy volunteers at any time of observation. However, no significant difference was calculated between Gram-positive and Gram-negative patients. Summarizing our results, the serum level of sCD14 could be proven to be a good prognostic marker in the course of Gram-positive sepsis. Increased levels are associated with a high mortality.

Abstract
The pathophysiologic backgrounds of anemia in malaria are complex and multifactorial. The purpose of the present study was to measure serum concentrations of erythropoietin (EPO) and to evaluate the adequacy of EPO production in patients suffering from acute Plasmodium falciparum malaria. Fifteen patients with complicated malaria were included in the study. Serum samples were taken on the day of admission, and days 7, 14, 21 and 28. Serum EPO concentrations were measured using an enzyme-linked immunosorbent assay. The median serum EPO concentration was 15.6 mU/ml on the day of admission (range 0.5-567) mU/ml, 10.6 mU/ml (1.2-863) on day 7, 11.8 mU/ml (0.5-72.8) on day 14, 10 mU/ml (0.5-74.6) on day 21, and 8.3 mU/ml (2.2-61.6) on day 28. Inadequate EPO production was found in 46.6% of the patients on the day of admission, which increased to 67% and 68% on days 7 and 14, and reached a maximum of 80% on day 21. Almost 54% of patients had inadequate EPO production on day 28. Our data indicate inadequate EPO production in patients suffering from acute P. falciparum malaria, which might contribute to the prolonged anemia observed in these patients.

Abstract
Thirty-seven patients with acute exacerbations of chronic osteomyelitis caused by methicillin-susceptible Staphylococcus aureus (n = 13), methicillin-resistant Staphylococcus aureus (n = 12), methicillin-susceptible coagulase-negative staphylococci (n = 9), methicillin-resistant coagulase-negative staphylococci (n = 1) and enterococci (n = 2) were treated intravenously with teicoplanin. After a loading dose of 7 to 16 mg/kg (median 11 mg/kg) for 4 to 7 days, patients received 9 to 25 mg/kg (median 14 mg/kg) on Mondays, Wednesdays and Fridays in an outpatient setting to reach trough serum levels between 5 mg/l and 15 mg/l. The duration of treatment ranged from 28 to 150 days (median 60 days). Cure was obtained in 14 (38%) and improvement in 17 (46%) cases, and failure was observed in 6 (16%) patients. Adverse effects occurred in 6 patients, and caused discontinuation of treatment in 3 patients. The financial savings exceeded US$60,000 per patient compared with the high hospitalization costs of inpatient treatment.

Abstract
We determined serum levels of laminin, carboxy-terminal cross-linked telopeptide, and carboxy-terminal propeptide of type I collagen (ICTP and PICP) in 27 patients with Graves' disease (GD) and in 31 patients with toxic nodular goiter (TNG). Elevated levels of soluble laminin and ICTP were observed in patients with GD prior to treatment (mean +/- SD concentration 1444 +/- 404 and 8.6 +/- 3.5 ng/ml, respectively), compared to patients with TNG (476 +/- 103 and 4.2 +/- 1.5 ng/ml) and normal controls (492 +/- 112 and 3.1 +/- 1.3 ng/ml, n = 34). In contrast, serum PICP concentrations were not different between patients with GD or TNG and normal controls. In GD patients serum ICTP and laminin levels decreased during thiamazole treatment and normalized within 4 and 8 weeks of therapy. There was no correlation between serum ICTP and laminin levels and serum levels of thyroid hormones and/or autoantibodies, respectively. Serum ICTP and laminin could be markers for alterations of extracellular matrix during GD and release of matrix components in the circulation and/or reflect an impaired clearance.

Abstract
We determined serum levels of laminin in 23 patients with Graves' disease (GD) and in 24 patients with toxic nodular goiter (TNG). Elevated levels of soluble laminin were observed in patients with GD prior to treatment (median concentration 1376 ng mL-1 [range 712-2402]), compared to patients with TNG (median 442 ng mL-1 [284-891]), and normal controls (median 492 ng mL-1 [range 235-675], n = 26), respectively. In GD patients serum laminin levels decreased during thiamazole treatment and normalized within 8 weeks of therapy. There was no correlation between serum laminin levels and serum levels of thyroid hormones and/or auto-antibodies, respectively. Whether serum laminin is a marker for alterations of extracellular matrix during GD and release of basement membrane components in the circulation and/or reflects an impaired clearance remains to be elucidated.
