Fosfomycin-trometamol (3 g granules dissolved in 200 ml of water for oral administration every 72h) and colistin (2x106 IU oral solution dissolved in 50-100 ml of water given orally every 6 hours) and gentamicin (an 80 mg oral solution dissolved in 50-100 ml of water given orally every 6 hours) will be administered in a double-blind fashion for a total duration of 7 days (day 1-7). The placebo treatment will be identical in taste, consistency, colour and packaging. To include the oral cavity into the eradication regimen, all medications should be gargled for at least 10 seconds before being swallowed.

Placebo preparations of fosfomycin, gentamicin and colisitin, identical in taste, texture and color will be administered at the same rate as the active comparator medication.

ESBL eradication regimen

Rapid and rational health-care interventions are of great importance to efficiently combat the emergence of resistant and virulent bacteria. In recent years, spread of ESBL-E on a global level has been observed.

For ESBL-E, effective eradication regimens are not yet available. The current study therefore aims to assess a new approach to ESBL-E eradication. To avoid administration of the eradication regimen to patients at low risk of subsequent BSI with ESBL-E, the study population will be restricted to immunocompromised high-risk patients.

Bloodstream infections (BSI) with multi-drug resistant (MDR) bacteria such as extended- spectrum betalactamase producing Enterobacteriaceae (ESBL-E) are associated with significant morbidity and mortality, particularly in the immunocompromised patient. In recent years, rapid spread of ESBL-E on a global level has been observed. While guidelines on effective infection control and treatment measures are urgently needed, the required basis of evidence is yet to be generated. Particularly data from interventional trials is lacking.

From October 2011 to December 2012, a multicenter cohort study on ESBL-E colonization and infection in haematology/oncology patients has been conducted within the Deutsches Zentrum für Infektionsforschung (DZIF) and allowed for a detailed description of the epidemiology of ESBL-E in this patient population. Based on these results, the sample size calculations for this study were carried out.

Rapid and rational health-care interventions are of great importance to efficiently combat the emergence of resistant and virulent bacteria. In recent years, spread of ESBL-E on a global level has been observed.

In 2012, the KRINKO (Kommission für Krankenhaushygiene und Infektionsprävention) at the Robert Koch Institute in Berlin, German, published their new recommendations on the management of colonization and infection with Gram-negative MDR bacteria, including ESBL-E. In high-risk settings, e.g. haematology/oncology wards and intensive care units, contact isolation is recommended for all patients who are colonized or infected with ESBL-E. While recommendations of the KRINKO are not legally binding, many institutions are now integrating these suggestions into their standards of care, given the recent increase in the prevalence of ESBL-E. This development is putting a considerable strain on patients and treating physicians. Firstly, previous studies have demonstrated the negative impact of long-term isolation on the patients' frequency of contacts with health care workers, a decrease in scores for self-esteem and an increase in scores for anxiety and depression.Secondly, proper contact isolation requires treatment in a single room. Many hospitals are, however, not equipped with sufficient numbers of single rooms, to accommodate all patients carrying MDR bacteria. Apart from problems associated with contact isolation, immunocompromised patients who are colonized with ESBL-E are at an increased risk of subsequent bloodstream infections (BSI).

Medical care providers are used to be faced with similar problems when dealing with methicillin-resistant Staphylococcus aureus (MRSA). However, nowadays, eradication regimens offer the possibility to remove MRSA from the skin and mucosa of colonized patients, thus interrupting its further spread to a considerable extent. For ESBL-E, effective eradication regimens are not yet available. The current study therefore aims to assess a new approach to ESBL-E eradication. To avoid administration of the eradication regimen to patients at low risk of subsequent BSI with ESBL-E, the study population will be restricted to immunocompromised high-risk patients.

The human intestinal tract is known to be colonized by hundreds of different bacterial species and other microbes. Based on the experience with fecal microbiota therapy in the treatment of recurrent Clostridium difficile infections, it can be hypothesized that the intestinal microbiome may influence the success or failure of the present study intervention. Thus, at selected sites, a metagenomic analysis of the intestinal microbiome will be performed to explore possible associations between certain microbiome patterns and the successful eradication of ESBL-E.

There is an ongoing discussion on whether antibiotic regimens used for eradication and selective digestive tract decontamination (SDD) might lead to the emergence of multi-drug resistant bacteria.11 Emergence of resistance under long-term administration of SDD to ICU patients has been previously reported.12 However, a recently published meta-analysis, including 64 studies in ICUs, of which 47 were randomized controlled trials and 35 included data for the detection of antimicrobial resistance, no relation between the use of SDD and the development of antimicrobial resistance could be detected.13 Even without this information, the risk for emergence of resistance should be classified as very low, considering that patients will receive eradication treatment for the duration of only seven days. Nevertheless, the possible emergence of non-ESBL multi-drug resistant bacteria in the intestine will be assessed during the study intervention.

Concerning the choice of an antibiotic regimen with a high chance of effectively eradicating ESBL-E from the gut, data from previous studies has been taken into account. Most previous study concepts were based on the idea of SDD.14-16 SDD aims to eradicate abnormal aerobic gram-negative bacteria, while preserving anaerobic bacteria. In this setting, the problem of adverse events caused by systemic effects of the antibiotics used can be discarded. However, if only locally active antibiotics are used for achieving eradication, patients are less likely to clear concurrent ESBL-E colonization of the throat, skin and urinary bladder. These body sites may then serve as a source of intestinal re-colonization with ESBL-E. Therefore, the current pilot study uses a combination of a non-absorbable enterally administered antibiotic and a systemic antibiotic. To facilitate the choice of an optimum non-absorbable antibiotic, antimicrobial susceptibility testing of clinical isolates of ESBL-E from haematological high-risk patients was carried out at the University Hospital Cologne in 2012. Virtually no resistance towards colistin could be detected (data not published), such that colistin was chosen as the non-absorbable component. As previous studies have shown promising results for a combination of colistin and gentamicin, the latter was added to the eradication regimen. Concerning the choice of a systemically active antibiotic, promising data on the clinical efficacy of fosfomycin in ESBL-E infections and in the reduction of ESBL-E in the intestinal flora have been published. Given the additional convenience of an available oral formulation - a prerequisite not given for most other ESBL-E active treatments - fosfomycin was chosen for combination with oral colistin and gentamicin. For the treatment of urinary tract infections, oral fosfomycin is usually administered as a single dose of 3g. However, several studies have assessed treatment of complicated or chronic urinary tract infections with repetitive administrations of 3g fosfomycin.

Since a single dose may not suffice to reduce the intestinal ESBL-E burden below the limit of detection, a schedule of 3g p.o. every 72h was chosen for this study.
