Prague, eLearning & the future of NoEs Prague is a city of wonderful architecture and fine music. It was selected to host the first and highly successful GRACE Workshop last October. The theme for the three day meeting was ‘Lower respiratory tract infections: current concepts in pathogenesis, microbiology, epidemiology and economic impact.’ The presentations were excellent and there was good delegate interaction. A full report can be read on page 7. The GRACE eLearning Resource (see WP12 at www.grace-lrti.org) is rapidly expanding and has about fifty presentations resulting from the presentations at the GRACE Workshop and three Postgraduate courses held to date. This is freely accessible and provides a rich source of up-todate material covering topics from basic science to clinical practice.

The future of the Networks of Excellence remains a hot topic of particular interest to researchers who have recognised the value and success of close of the initiative which integrates multiple partners around a research theme. At a recent Open Forum on the future of European Networks of Excellence held in Brussels in November (see Publications/Presentations at www.grace-lrti.org) five NoEs which included GRACE, made a strong plea for sustainable funding.

News New GRACE members at Cardiff I am very pleased to announce three new members of the GRACE team in Cardiff. Dave Gillespie, a sandwich year maths student, and Dr. Mark Kelly (statistician) are undertaking the data management and analysis of GRACE-01. In addition, Lucy Cooper has joined Lucy Brookes-Howell working on the qualitative study, GRACE-02. We are looking forward to their contributions in helping further understand the vast amounts of data gathered last winter. Chris Butler

GRACE-01 Update The GRACE-01 analysis is proceeding apace. The current focus is to investigate associations between both clinician and patient reported symptoms and patient outcome. Before this could begin however, an exhaustive validation process was undertaken. This involved assessing the validity of creating a total symptom severity score by summing the severity score for each symptom. Our next step involved investigating missing values in the patient symptom diary. If a patient completed at least 80% of the symptom diary on a given day the remaining missing values were replaced with the mean of the other symptoms for that day. Once the total symptom severity scores were successfully cleaned and validated the analysis could begin. In order to investigate associations between patient outcome and clinical management for each of the GRACE-01 sites, the patient diary symptom-scores were modelled. Many modelling approaches were investigated before a suitable one was chosen. This is currently being written up for publication in a high-ranking journal. The next objective for the GRACE-01 study team is the dissemination of the results of the analysis currently being carried out. We have also met with the WP11 team and given them access to the GRACE-01 datasets so that they can estimate the economic burden associated with treatment of LRTI in different countries and obtain baseline data for modelling the cost-effectiveness of diagnostic strategies. Mark Kelly and Dave Gillespie
GRACE-02 Update, December 2007 These are busy times for GRACE-02. An amazing 188 interviews have been conducted with Balatonfüred, Cardiff, Lodz, Southampton, Tromsø and Utrecht having closed recruitment after doing a fantastic job of recruiting, arranging and carrying out their interviews. The remaining 3 networks, Antwerp, Barcelona and Milan, are attempting to conduct their final handful of interviews. In Cardiff, we are hard at work scrutinising and analysing the interview data and fieldnotes. The GRACE team in Cardiff is lucky to have been joined by Lucy Cooper, Research Associate helping with analysis of the GRACE-02 data. Joining us at this stage, Lucy C has had to engage with the data quickly, and has already proven herself an invaluable member of the team. A detailed framework of coding categories has now been developed, based on a combination of the GRACE research aims and themes emerging from the interviews themselves. This framework is currently being applied to the Clinician interviews through thematic coding. The management of data and coding is assisted by the use of the software package, NVivo. It is important to consider each network as a set in its own right before, at a later date, similarities and variations across networks can also be explored. Therefore, we can only begin detailed analysis once we have a complete set of transcribed and translated (when necessary) interviews. We are pleased to report that full, detailed thematic coding has been now carried out on all Clinician interviews for which we have received a complete set of translations; Antwerp, Balatonfüred, Cardiff, Lodz, Southampton and Tromsø.
GRACE-03 Update I would like to start by thanking all the members of the GRACE-03 Delphi panel for giving up their valuable time to contribute to the study. The process has finished and is in the analytical stage presently. The GRACE-PAT leaders are assessing the results with relation to the integration of the definitions in to WP9 and 10. The finalised definitions will be presented the annual GRACE meeting in Budapest and will also be published in the next issue of GRACE news. The process evaluation has shown that, on average the panel members agreed with the statements ‘The process was easy to undertake’, and ‘The Delphi task was a useful and worthwhile task to undertake’. The development of a strategy to assess the views of experts within the respiratory infections community has been a real success. From the first tentative steps taken in the set up of GRACE-03, supported by the excellent work of the GRACE IT platform, an invaluable research resource has been created. With the utilisation of the GOS, the expert knowledge of all involved in GRACE can be canvassed. One such opportunity for this technology comes in the form of CHAMP. This expands upon GRACE-03, quite literally, in terms of the number of clinicians involved, in disease categories, including both LRTI and URTI and finally including both adults and children. Giles Greene
CHAMP
The GRACE-01 data produced an enormous wealth of data, with a vast number of potential for informing additional research. One such example of this is the SMoking And Respiratory Tract Infections in Europe (SMARTIE) study which has been proposed and is awaiting funding. The study will examine the management of patients across three population groups, smokers, ex-smokers, and non-smokers, across Europe. It has already been shown that smokers are more likely to be prescribed antibiotics despite no difference in severity score. Further analysis using multi-level modelling will explore the relationships in much greater detail.
Analysis of the Clinician interviews from the remaining three networks will take place early in 2008 before the important task of analysing all Patient interviews. It is important that we receive translations of interviews as soon as possible in order to allow time for the lengthy analysis process. We have currently received translations of 85% of Clinician (6 networks with complete sets) and 69% of Patient (4 networks with complete sets) interviews. We continue to be extremely grateful to the NNFs and interviewers who are working so tirelessly on GRACE-02 and hope that, with one final push, all translations can be finished and any outstanding supplementary data forms input into GOSwp8q.
CHAMP moves beyond LRTI to other infections. WP2 consists of a quantitative and qualitative study with its aim to explore current preventions and management of respiratory tract infections in European primary care and investigate perception, expectations and illness behaviour of primary care patients with respiratory tract infections. The quantitative study will comprise of a web-based vignette-style questionnaire, which is currently being developed, that will determine variation in the management of common infections in primary care both between and within countries. The qualitative study will build on work carried out by GRACE-02, focussing more specifically on the views of parents of child patients with common infections.

WONCA Europe 2007 in Paris
Paul Van Royen opens conference
Ruut de Melker amidst the speakers on his symposium
In many ways this WONCA congress was a very special congress and a very successful one as well. Perhaps it was the mild autumn weather that made us happy and relaxed, perhaps it was the strike of public transport that kept us away from the seductions of the city itself, but most importantly it was the good organisation and new focus of WONCA Europe that gave the GRACE researchers who were present a very good feeling about this congress. Our project was clearly present from the start: Paul van Royen mentioned GRACE as one of the first good examples of European collaboration in his keynote lecture on the first day. Triggered by this excellent lecture all participants were reminded of something about GRACE in their congress bag and several were spotted reading the smart GRACE newsletter that Samuel had managed to get in the standard information package each participant had received! There were many presentations on respiratory tract infections and the discussions were lively and very interesting. Our knowledge of French was tested sometimes when presenters and part of the audience switched to their native language, but that was hardly a problem. Kerry Hood had the opportunity to present latest GRACE results during a symposium that Paul Little had organised and as seen before in 2007 the reactions to her excellent presentation were enthusiastic and full of admiration. And there was a symposium on behalf of the 75th birthday of Ruut de Melker, one of the pioneers of research on respiratory tract infections in primary care, where several GRACE researchers contributed to. During the conference there was also a meeting of so called Special Interest Groups, where GRIN was also invited. The board of WONCA invited the representatives of these groups to play a more active role in the scientific programme of coming WONCA Europe congresses. This invitation was gladly accepted by the groups present, and this means that GRIN will be able to organise special symposia and workshops in future congresses where GRACE can be presented and discussed with European researchers and general practitioners. A very good prospective! And last but not least there was rugby! Straight after the congress your reporter was dragged into an Irish pub (name me a city without them) by some GRACE researchers who will remain anonymous and drowned in madness, beer and a tremendous victory by the South Africans. A GRACE-full end of a good congress! Theo Verheij
European Parliament session (European Antibiotic Day)
Herman Goossens on Belgian antibiotic policy
At a meeting hosted by the European Parliament on 16 October 2007, the Director of the European Center for Disease Control and Prevention (ECDC) announced the launch of a European Antibiotic Day for autumn 2008. This announcement received strong support from Commission officials representing DG SANCO and DG RTD at director level, Member State public health attaches and sponsoring member of the European Parliament John Bowis. In the meantime, it has been decided that ECDC will coordinate this annual event, which will take place on November 18 of each year. ECDC seeks to maintain and increase awareness of the issue of antimicrobial resistance at EU and Member State level in order to encourage effective public health action. The major focus of this European Antibiotic Day will be to support existing national information campaigns on rational use of antibiotics and to foster the emergence of new national initiatives in this area. The added-value of an EUwide approach is to provide a focus point for consistent messaging and awareness raising across the EU on the day, and in the build up to the day. The first European Antibiotic Day on November 2008 will focus on informing the general public about rational antibiotic use. Meetings have already been planned during the Slovenian (first semester 2008) and French (second semester 2008) presidency to prepare this important event.

Currently 10 different networks recruited over 440 patients, including over 60 patients on study medication. CRF data entry in the GRACE Online System (GOS) is very complete. Nearly all patients with LRTI got an X-ray. And in 75% sputum is collected of which 60% is of good quality. We planned to start WP9 and WP10 October 1st 2007. As was to be expected, we had to face some starting problems. Study medication was not distributed yet, approval of several Ethics Committees was still outstanding, and some countries had to wait for a signed contract from the European Commission. In the mean time, however, all of these issues are taken care of.

WP9 versus WP10 The primary care network (PCN) Antwerp was the only one that started with patient recruitment as planned, quickly followed by Cardiff, Mataro and Rotenburg. All those inclusions were patients for WP 9, because at that time the study medication was not available yet. After 6 weeks, the memorable 15th of November, Cardiff included the first patient taking study medication, and thus the first patient for WP 10!

See www.grace-lrti.org/wp9-10 for the most recent inclusion figure. Data collection For all patients in WP9 and 10 registration forms, diaries, the collection of blood, swabs, sputum and test results have to be entered in the GRACE Online System (GOS). So far, almost all these data are really very complete in GOS. The most difficult part regarding the data collection are the diaries. This is the only item in the whole data collection that is below 95%. Laboratory facts According to the data in GOS on January 22nd, 89% of the sample kits arrived in the local labs within 1 day after sampling. This is very good! In 75% of patients with LRTI sputum was collected. This is a very high number compared with other studies! Also the quality of the sputum is good. In 60% of the cases more white blood cells than epithelial cells were found. So far, Haemopilus spp. and S. pneumoniae were identified most often in the sputum. Many thanks to all who are involved and busy making the data-collection of WP9-10 a success! Saskia van Vugt

Pneumococcal genomics in GRACE (WP6) Lower Respiratory tract infections (LRTI) remains the leading cause of deaths world-wide (see figure). A major part of these infections are caused by pneumococci. It has been estimated that between 1 and 2 million people die from pneumococcal diseases every year. Workpackage 6 (WP6) deals with pneumococcal genomics and this workpackage is included in GRACE-TECH, the platform within GRACE for technological developments. It is headed by Birgitta Henriques Normark at the Swedish Institute for Infectious Disease Control, Solna, Sweden, and other partners involved are Herminia de Lencastre at ITQB, Lisbon, Portugal, David Holden at Imperial College, London, UK, Regine Hakenbeck, at Kaiserslautern University, Kaiserslautern Germany and Staffan Normark at Karolinska Institutet, Stockholm, Sweden.

The aims of WP6 include collection of pneumococcal isolates from the clinical platforms within GRACE and to characterise these isolates with genomic molecular techniques and selected isolates with in vitro and in vivo virulence analysis. Antibiotic resistance types, serotypes, genotypes, and virulence characteristics will be correlated to clinical pictures of LRTI. We are now studying the discriminatory power of Pulsed Field Gel Electrophoresis (PFGE) using different restrictions enzymes and compare this method with Multi Locus Sequence Typing (MLST) as a quality assurance testing to decide the appropriate methods to be used in GRACE. Furthermore, we have so far constructed a micro-array chip consisting of two of the sequenced pneumococcal genomes, TIGR4 and R6. This chip will be used to study gene content in some of the collected isolates within GRACE. The pneumococcal capsule (of which 90 serotypes exist) is an important virulence factor in pneumococcal disease and in our previous work we have found that certain serotypes correlate to invasive disease while others are more common among carriers. Also, some serotypes are more common causing invasive disease in patients that have underlying diseases or disorders like immunodeficiency. Still we lack information on why pneumococci cause mainly carriage but sometimes disease such as LRTI and invasive diseases. By using micro-array analysis of invasive pneumococcal isolates we have shown that virulence factors differ between pneumococcal strains and so far no single virulence factor can be attributed to explain pathogenesis. However, we have recently shown that one single virulence factor, in this case a pilus like structure on the pneumococcal surface, may be an important factor for the spread of antibiotic resistant pneumococal clones around the world. Within GRACE we expect to detect new and unusual antibiotic resistance profiles and to get a picture of the pneumococcal clones causing LRTI and their spread within the community in the different countries in Europe that participate in GRACE. Also, we hope to discover novel virulence factors important for pathogenesis among our clinical isolates using comparative genomics and studies of virulence both in vitro and in vivo.

Coris was the first company to propose a rapid membrane test for detecting Rotavirus in stools. The enteric range of products rapidly grew and very quickly, the company decided to develop new products dedicated to the detection of respiratory pathogens, keeping the same technological features: quick, simple and reliable. Along with these rapid membrane antibody-based tests, we also developed a new proprietary technology called Oligochromatography and based on a direct membrane hybridization after nucleic acid amplification by PCR or NASBA. At the present time, we offer a complete “homedeveloped” range of products to detect either enteric pathogens (Rotavirus, Adenovirus, C. parvum, G. lamblia, E. coli 0157), respiratory pathogens (RSV, Adenoviruses, Influenza A, Influenza B) aside of those for detecting leishmaniosis (L. spp with L. donovani and L. infantum) and trypanosomiasis (T. brucei and T. cruzi) that allow Coris to be leader in the Belgian market, in Ireland, New Zealand, and South Africa and present in more than 70 countries worldwide. Moreover, we are engaged in a Total Assurance Program, being ISO 9001 & ISO 13485 certified by SGS and all our products are CE marked. All these features brought the turn-over from 46,000 in 1997 to more than 1,500,000 in 2006.
Since Coris is working in a highly competitive market, it was a decision to invest human and financial resources to develop new products and new technologies in order to face the challenges of the diagnostic market for the next decade. To reach this goal, amongst the 21 persons presently working in the company, 7 are R&D people and about 30 % of the turn-over is reinvested in R&D activities leading to new products, patents, scientific posters and articles. Coris is able to manage protein-based tests developments as well as nucleic acid-based ones, with gold particles and/or latex microspheres. Of course, it is of utmost importance to get involved in scientific networks and that’s the reason why Coris is still partner in several EC financed projects of the FP6 framework whose details could be found in our Website (www.corisbio.com). Within the GRACE program, Coris is engaged in developing diagnostic tests based on both immunological and molecular tools. Coris has developed a L. pneumophila test with a new patented device, so-called GDT (for Gravity Driven Test), and is working in adaptating the Pathofinder MLPA technology with Coris’ patented Oligochromatograhy technology for detecting 4 respiratory pathogens including Mycoplasma pneumoniae, RSVA, RSVB and Influenza A.

1st and 2nd GRACE Workshop held in Prague in October 2007! The first two stand-alone GRACE Workshops took place in Prague on the issue of Lower respiratory tract infections: Current concepts in pathogenesis, microbiology, epidemiology and economic impact. The topics were drawn from the GRACE Curriculum developed by the GRACE Education and Curriculum Committee (WP 12), led by Roger Finch and Francesco Blasi for ESCMID and ERS, respectively. A shared session in the beginning was followed by two separate workshops which dealt with The bacteriology of respiratory tract infections and The epidemiology and economic impact of common respiratory infections, respectively. The presentations were outstanding and much appreciated by the delegates, who were both science and medical graduates from the specialties of Primary Care, Clinical Microbiology and Infectious Diseases. The shared session was dedicated to a broad review of (i) the diverse nature of host defences within the lung divided into innate and adaptive immunity, also emphasizing the importance of innate immunity and pathogen-associated molecular patterns (PAMP) and (ii) the spectrum of host-pathogen interactions in relation to microbial colonization and invasion. Adhesion and immune evasion are critical to host cell entry and are pathogen variable. This was exemplified with the well characterized pathogen Streptococcus pneumoniae and in the less well understood situation of chronic lung infection spanning from Chlamydia pneumoniae to Mycobacterium tuberculosis. The shared session concluded with a review of cell-to-cell communication by bacterial quorum sensing (QS) in lung disease. The evening of the first day provided an opportunity for GRACE researchers from WP9 and 10 to present Research in progress. Theo Verheij set the scene for the major observational case control study which will recruit 3000 adults with LRTI and a matched control population. Clinical features are being recorded and a variety of investigations conducted. Some of the preliminary results were presented as well as the intervention study in which amoxicillin and placebo will be compared. Jacqui Nuttal and Kerry Hood reported on the logistics and implementation of what is the largest ever prospective clinical study of LRTI in the community. Preliminary research findings based on in-depth interviews with all patients recruited was most informative and has already identified some of the key variables across Europe. The presentations complemented those reported in Stockholm and published in the October 2007 issue of GRACE News. Workshop 1 focussed on The bacteriology of respiratory tract infections. After a review of the microbial epidemiology of community-acquired LRTI, both current and future microbiological laboratory investigations of LRTI emphasized the value of a diagnosis in terms of targeted and appropriate therapy, as well as supporting surveillance and outbreak recognition. While the importance of Streptococcus pneumoniae, Haemophilus influenzae, Legionella, Mycoplasma and Chlamydia spp. – which all were subject of excellent presentations – is beyond any doubt, did two timely reviews remind us of the continuing importance of anaerobic bacteria in respiratory infections and of the growing importance of Staphylococcus aureus as an emerging respiratory pathogen. Workshop 2 dealt with The epidemiology and economic impact of common respiratory infections. An introduction to ‘antigenic cartography’ showed a possible way to predict the evolution of an influenza epidemic. The impact of pollutants, of antibiotic use and misuse on LRTI were discussed on a European basis. Furthermore, COPD and CAP were viewed on in terms of prevalence and cost to society; the interrelationship between infections and asthma; the importance of cystic fibrosis management in adults; and the impact of vaccination on Streptococcus pneumoniae infection. If your curiosity has been raised for some topics: the material from the GRACE Workshops in Prague is now accessible on the e-learning platform on the GRACE (www.grace-lrti.org). There you can find a rich resource of lecture material, such as webcasts, presentation slides and references that you are encouraged to access and disseminate to other colleagues and students.
