Detect Novel Pathogens and Characterize Emerging Infections

Prospective Studies

Infectious disease is the single biggest cause of death worldwide. New infectious agents,such as the Severe Acute Respiratory Syndrome coronavirus and new strains of influenza continually emerge and require new investigations to understand pathogen biology and pathogenesis in the host. Witness the Influenza A pandemic. Concerns about new viruses and their impact on health and the economy are also increasing. Current alerts sent out by the Ministry of Health (about the novel coronavirus and the Avian influenza A virus) are but cases in point. These likely reflect advances in science, which have allowed novel pathogens to be identified. Because of its geography, Singapore is vulnerable to new pathogens through importation or the global travel of its citizens. Hence we must be ever ready to meet unexpected challenges anytime. On the administrative front, Singapore General Hospital has a Disease Outbreak Task-force which has in place many plans that can be activated should there be a large-scale epidemic. What is missing thus far is a program that will enable us to perform scientific studies in the setting of an epidemic. Hence in this study, we will, in collaboration with the Program in Emerging Infectious Diseases (EID) in Duke-National University of Singapore Postgraduate Medical School, attempt to (i) detect novel, previously undescribed pathogens; (ii) characterize viruses (not necessarily novel but emerging and re-emerging) that are raising concern or causing clusters or epidemics in the hospital and/or country; (iii) characterize immune responses to such viruses in healthcare workers as well as patients (those affected by these viruses and those exposed to the affected). The techniques that will be used will be those not routinely available in a hospital's service labs. Some patients will remain undiagnosable with the best available technology. Since new laboratory tools that can detect previously undiagnosed pathogens may become available in the future, the study also aims to archive specimens from patients whose illnesses remain undiagnosed.

Zika Virus Infection's Neonatal and Pediatric Consequences in French Department of America

Zika Virus Infection on Fetus and Child During the Pregnancy

The Zika epidemic has spread into the three French Overseas Departments in the Caribbean (DFAs). It is therefore urgent to set up tools to collect clinical and paraclinical data for the evaluation of potential complications due to having ZIKV infection during pregnancy. This study is meant to collect, within usual care practices, clinical and paraclinical information (including imaging and laboratory results) as well as biological samples allowing the precise description of the consequences of ZIKV infection during pregnancy. This study is the 2nd arm of a global research program in the 3 French Overseas Departments in the Caribbean. It is complementary to the first arm (ZIKA-DFA-FE) consisting in the follow-up of women in the French Overseas Departments who are pregnant during the Zika epidemic period. The study population is made up of infants born during and up to 9 months after the end of the Zika epidemic period in the French Overseas Departments. The data and biological specimens collected for this project will be done so through the recommended standard of care which has been put in place considering the ZIKV epidemic in the 3 French Overseas Departments, upholding existing recommendations (profession and/or recommendation from the public health authorities)

Immunological Characteristics of Maternal-fetal Transmission of Cytomegalovirus in Pregnancy

PregnancyCytomegalovirus Infections1 more

Analysis of several characteristics of blood from pregnant women with CMV infection according to maternal-fetal transmission. These include CMV viral load, cytokine profile in response to in-vitro stimulation with CMV peptides, meticulous analysis of anti CMV antibodies, maternal DNA polymorphism and microarray of gene expression.

Nasal Specimen Collection Study in Patients With ILI and/or ARI in an Outpatient Setting

Influenza-like IllnessInfluenzal Acute Respiratory Infection

This is a prospective specimen collection study targeting patients presenting with Influenza Like Illness (ILI) and/or Acute Respiratory Infection (ARI) in an out-patient setting. A non-invasive, user friendly sampling technique, using midturbinate flocked swabs will be used. These nasal swabs will be collected in different volumes of viral transport media (0.5mL and 3.0mL), for different dilution range of the viruses present in the collected biological specimen. The collection of nasal swabs samples will support the optimization of point of care detection methods for respiratory viruses responsible for ILI and/or ARI.

Autoantibodies Against Specific Cytokines in Adults With Severe Mycobacterial Infection

Mycobacterium Infection

In adult, the prevalence of mycobacterial infections is increased with age is largely unknown. IFN-gamma-IL-12/23 axis or NF-kappaB pathways might also plays crucial roles in adult against mycobacteria. Based on this hypothesis, the investigators had applied a functional assay to these pathways in patients with mycobacterial infection.
