ARC confidential RISKMAN RA2: Life-time prediction bu micro & nanosensors and diagnostic tools Draft version of an IP -or NoE proposal (6th FP) submitted under thematic area 3 (Nanotechnology and Nanosciences, knowledge-based multifunctional materials, new production processes and devices) Reduction of hospital mortality by micro/nanotechnology-based diagnostic tools Acronym: Nano-ROM Nosocomial (= hospital-acquired) infections and cancer are primarily responsible for the continuously increasing incidence of mortality in hospitals. In counteracting this development, early preventive diagnosis is critical. Here, new rapid , nano- and microbased diagnostic systems show great potential The major objective of the project is to develop improved strategies for diagnosis, prognosis, more effective and personalised therapy for combating nosocomial infections and cancer. The proposed multidisciplinary and nanotechnology-assisted approach is aiming to reduce mortality rates in hospitals by translating research results into applications which enable early diagnosis, reliable prognosis, medical condition- and patient-tailored therapies and are implementable in the daily clinical practise. One task of the project is the establishment of novel assays for fast and reliable diagnosis of nosocomial infections (in particular sepsis) including antibiotic resistance testing and expert system-based decision support systems (DSS). The second task is the development of new diagnostic markers for high incidence cancers (lung, breast, colon, prostate etc.) and tumour cells circulating in the blood (minimal residual disease) which allow on one hand early diagnosis and on second hand differentiation of clinically and histologically uniform tumors into (so far undistinguishable) cancer subclasses enabling more differentiated prognoses and new patient-tailored, therapeutic strategies. Aim: The aim of the proposed multidisciplinary consortium is to generate new micro/nanotechnology-based diagnostic, prognostic and therapeutic strategies to reduce the incidence of mortality in hospitals. The project will focus on the development of novel and fast diagnostic tests for nosocomial infections (in particular sepsis) and molecular markers for diagnosis and more differentiated prognosis of high incidence cancers (lung, breast, colon, prostate etc.) including surveillance of metastasis (minimal residual disease). Rationale: Recent studies have elucidated a significant and not longer ignorable increase in hospital mortality. The leading causes for death beside coronary heart diseases are cancer and hospitalacquired (nosocomial) infections. Cancer About 53 million people die from cancer every year. In the developed world cancer accounts for 21% of all deaths. Lung cancer is the commonest cause of cancer death in the western world, followed by breast, colorectal and prostate cancer. Unfortunately cancer incidence and mortality are continuously growing. Therefore actions for combating cancer based on early detection of both primary tumours and metastasising tumour cells become a big issue. Whereas cancer detected at an early stage in most cases is curable, tumour metastasis as such 1 ARC confidential is the main cause of lethality in cancer patients. Cellular metastasis is based on detachment of cells from the primary tumour, invasiveness through surrounding tissues and blood vessels and active migration towards the tissue where secondary tumours develop. Therefore, researchers are intensively working on diagnostic strategies which allow the detection of circulating tumour cells in the blood (minimal residual disease, MRD) before a secondary tumour can develop. Similar to an early detection of the primary tumour, the identification of circulating tumour cells would significantly increase cancer survival rates due to the possibility of case-specific and early therapeutic intervention. Hospital-acquired (nosocomial) infections Nosocomial (= hospital-acquired) infections typically affect patients who are immunocompromised because of age, underlying diseases, or medical or surgical treatments. Nosocomial infections result in substantial morbidity, prolonged hospital stay, increases in direct patient care costs and last but not least mortality. Although our understanding of the epidemiology of nosocomial infections has increased dramatically over the last two decades, the incidence of nosocomial infections continues to affect about 5% of hospitalised patients. Sepsis Sepsis can be defined as the body’s response to an infection. An infection is caused by microorganisms (usually bacteria) invading the body, and can be limited to a particular body region (e.g., a tooth abscess) or can be widespread in the bloodstream (often called "septicemia" or "blood poisoning"). Sepsis is the leading cause of death in noncoronary intensive care unit (ICU) patients and the 11th leading cause of death overall in the US (Centers for Disease Control and prevention CDC, National Vital Statistics Report, 2000). Despite enormous investment in intensive care, sepsis has been associated with mortality rates ranging from 28% to 50%. It is estimated that more than 700.000 individuals develop severe sepsis (sepsis associated with acute organ dysfunction, hypoperfusion or shock) in the US each year, with similar estimates for Europe. Extrapolated to a global population, this represents several million cases of severe sepsis annually worldwide and 1400 people dying from sepsis every day worldwide. The CDC recently published a report showing that U.S. sepsis cases had increased by more than 300 percent in the past 25 years. The healthcare cost of the condition amounts to more than $17 billion in the United States and more than $7 billion in Europe. In the next decade a further striking increase in sepsis incidence is expected. Advances in medical technologies and procedures may contribute to the rise in cases of sepsis. Among these are increasingly aggressive cancer therapies and the increasing use of invasive devices and procedures for a variety of medical conditions. Overall, improvements in the survival rates of patients predisposed to sepsis, such as the elderly, premature neonates, and patients with comorbid conditions will also contribute to the increased incidence of this disease. Also, the widespread use of broad-spectrum antibiotics has increased the rates of both antibiotic resistance and nosocomial infections, which will have a direct impact on the incidence of sepsis (Opal and Cohen, 1999). General Approach and Methods: Cancer 2 ARC confidential One part of the proposed project is aimed at uncovering mechanisms underlying cancer and metastasis by using micro/nanotechnology-related tools such as DNA microarrays, highthroughput proteomic devices, tissue arrays as well as microfluidics-, biosensor-based or single molecule- techniques to identify „biomarkers“ which can be used for an improved, more differentiated cancer diagnosis/prognosis and therapy thus reducing mortality. Prerequisite for the identification of reliable cancer –and metastasis biomarker are large tumour collectives, extensive studies on tumour gene and protein expression, on tumourspecific changes in gene copy numbers (matrix-CGH) and finally the identification of key molecules from the huge data sets generated by applying state-of-the-art bioinformatic tools/expertise. The proposed multidisciplinary consortium possesses the necessary knowhow and background to succeed due to its expertise in the fields of clinical oncology, genomics, proteomics, bioinformatics and bionanotechnology. The ultimate goal of the cancer part of the project is to develop rather simple (suitable for clinical practise) and sensitive diagnostic strategies based on the biomarkers identified. These can include medium-density oligonucleotide microarrays including marker genes (flat arrays, lab-on-the-chip systems), new, strongly predicative/prognostic antibodies for immune histochemistry and single molecule detection-based assays for minimal residual disease diagnosis. Sepsis The other part of the project will focus on developing fast and reliable diagnostic tools for sepsis causing microbes and their respective antibiotic resistances using DNA microarrays and microfluidics (lab-on-the-chip) techniques. In addition, obtained results will be completed by decision support software solutions based on expert systems. These are databases including up-to-date knowledge of pathogens and their incidence in sepsis paired with probabilities for those pathogens to develop specific mechanisms of antibiotic resistance. A second focus of investigation will be uncovering host-pathogen interaction in sepsis using a functional genomics approach on human and microbial whole genome microarrays. These studies, requiring a lot of bioinformatics work, will eventually lead to new therapeutic strategies in sepsis.
