Detailed Description
Hospital and nursing home patient recruitment:
COVID-19 positive/ SARS-CoV-2 inpatients and non-hospitalised patients (n = 700) aged 18 years and over tested at the WHSCT, BHSCT and SHSCT and have been admitted to COVID-19/ SARS-CoV-2 hospital wards (including from the Intensive Care Units) or out-patient and residents of trust affiliated nursing homes will initially be approached by their clinician, senior nurse or an NICRN research nurse. Investigators will speak to the patient(s) about the study and if the patient is interested, verbal consent will be gained for the researcher to follow up with a Participant Information sheet (PIS) (appendix 6). Those interested patients fulfilling the inclusion criteria can then speak directly face to face (whereby the nurse will arrange a convenient time for researcher to visit the patient) to the researchers, the study will be discussed in detail and any issues will be addressed. If participants are still interested in participating, written informed consent (appendix 7) will be obtained by the researcher(s) prior to enrolment on the study.
In the case of those ALC, and where a family member is not available to act as a nominated person the research team in conjunction with the PI will identify a nominated person who is unrelated to the conduct of the research and willing to provide a declaration for this study. The nominated person will always be a member of the nursing staff or the management team and part of the wider multi-disciplinary team within the hospital ward or nursing home facility of the individual lacking capacity. The nominated person will also be provided with an invitation letter and PIS (appendix 13) and any queries answered, the nominated person can then contact the research team if it is thought the potential participant would have been interested in this research. The potential participant will not be enrolled on the study until full informed consent (appendix 14) has been given by the nominated person. This will still apply at all time points for those individuals who are unlikely to regain capacity and for those patients in hospital who are sedated/ventilated due to their COVID-19 symptoms, who may regain capacity. For those patients, capacity will always be assessed by a member of their direct clinical care team, the nurse in charge/manager in the nursing home and the PI at each hospital site who will be the consultant on or linked to the COVID ward (The person assessing capacity will be recorded at all time points and a record kept). For those that regain capacity during the duration of this research, a participant information sheet will be provided (appendix 4) to read and consent (appendix 5) will be sought if there are wishes to proceed with the study. If participants do not wish to continue, the option will be provided for any samples and data to be withdrawn and destroyed.
Sample Collection: Once informed consent has been obtained each participant will provide (i) one 30 ml whole blood sample, a saliva sample (~4ml) and one set of up to five 20ul dried blood spots (DBS; equivalent to five finger lancet blood droplets) and a lateral flow assay for COVID-19 antibodies performed at recruitment (between 0 and 10 days of symptom onset), (ii) again between 14-28 days after symptom onset (iii) again samples will be collected only if pneumonia occurs during episode (usually only in severe symptom cases) (iv) In addition, where possible samples will be collected at post 3 months, 6 months, 12 months and 18 months post symptom onset, the latter sample collections will take place at an agreed convenient time and place.
Hospital and nursing home staff recruitment:
All HSC employees aged 18 years and over, employed within facilities at the WHSCT, BHSCT and the SHSCT and trust affiliated nursing homes within the trust areas (n = 500) are eligible to participate in this research. Trust/nursing home wide emails with an attached PIS explaining the study (appendix 6) will be sent to all staff. In addition, information regarding the research will be put on Trust and Nursing home websites and social media platforms e.g. Facebook and Twitter. Posters (appendix 8) will also be placed in communal areas ensuring information can be accessed by everyone. Staff will be directed to the researchers on the study via email or phone to discuss the study in more detail. For those who still wish to participate and who meet the inclusion criteria, written informed consent (appendix 7) will be obtained by the researcher(s).
Sample Collection: Once informed consent has been obtained each participant will provide (i) one 30 ml whole blood sample, one set of dried blood spots (DBS) and a saliva sample (~4ml) at recruitment. Then, only if SARS-CoV-2 symptoms such as a high temperature/a new continuous cough https://www.nhs.uk/conditions/coronavirus-covid-19/check-if-you-have-coronavirus-symptoms/ experienced during 2 week post recruitment period: (ii) a saliva sample, one 30 ml whole blood sample and one set of dried blood spots (DBS) and a lateral flow assay for COVID-19 antibodies performed (between 0 and 10 days of symptom onset), (iii) a saliva sample, one 30 ml whole blood sample and one set of DBS and a lateral flow assay for COVID-19 antibodies performed between 14-28 days after symptom onset (iii) a saliva sample, one extra set of 30ml whole blood and DBS to be taken only if pneumonia occurs during (usually only in severe symptom cases) (iv) In addition, where possible sample will also be collected at 3 months, 6 months and 12 months of symptom onset. Sample collections will take place at an agreed convenient time and place.
Data Collection for all cohorts (including COVRES2 follow up):
The phenomic data collected will align with international/National data for phenotypic data collection (HDRUK). After informed consent (appendices 3, 5 & 7) is obtained by a member of the research team, participants will be asked to answer a health and lifestyle questionnaire at each timepoint (Appendix 9) that includes questions about their general medical and clinical history such as comorbidities, medications, respiratory illness, COVID-19 symptomatology, time to admission to hospital (if hospitalised) as well as lifestyle habits, family history etc.
Missing information will be collected by the researchers by accessing the participants electronic care records or the participants medical notes provided concent has been obtained for this option. Demographic variables in addition to age and gender will include height, weight and blood pressure will also be retrieved from the participants electronic care record. The researchers will have an honorary contract within the Health Trust(s) and will have approval and training to access and to use the patient care records. In case certain information is missing, the researchers will ask permission to follow up with the patient at a later time by phone. All medical records will be accessed on the Altnagelvin hospital site at C-TRIC and information will be manually inputted to a database on a university password protected and encrypted laptop.
Participants will also be asked whether consent is cnfirmed at each time point, to complete a validated mental health questionnaire, the General Health Questionnaire (GHQ-12), (appendix 10) to assess the association between their condition or perceived risk and their mental health and wellbeing. The researchers will arrange for completion of this questionnaire at a convenient time for the participant either on the day of recruitment, during the follow up visits, online or by phone.
Participants also have the choice to consent to be contacted again to receive information regarding future studies.
Sample processing, storage and analysis
Saliva ~ 4ml will be collected in Oragene saliva collection kits (DNA Genotek), processed and analysed for COVID-19 genome sequencing and microbiome analysis.
Whole blood samples will be processed to extract plasma and flow cytometry. Paper discs will be punched out of dried blood spot samples (DBS) and protein, prescribed medication, drug metabolites and DNA extracted by addition of a routine elution buffer. Lateral flow data will be logged at the time at of assay and where possible dedicated COVID-19 app photograph of test strip result archived. DBS extracts and plasma samples will be logged, aliquoted and labelled with unique bar code identifiers prior to storage at -80'C in the Northern Ireland Centre for Stratified Medicine (NICSM) until analysis. DBS protein (IgG, C-reactive protein and cytokines and plasma will be analysed using ELISA and OLINK or drug metabolites by mass spectrometry. With participant agreement, DNA extracted from DBS/blood samples for future whole genome sequencing (WGS) and extracted drug metabolites will be stored at -80C in. A whole genome sequence will be generated from each participant DNA sample. A selected cohort of patient samples will also be subjected to transcriptomics (RNA Seq), microbiome and methylation analyses.
Whole blood samples and swab extract will undergo viral genome analyses sequencing, transcriptomics, epigenetics, single nucleotide polymorphism (SNP) genotyping, WGS and RNAseq generation. Sample analysis will be performed at NICSM by the researchers or by a third party such as the virology laboratories at Queens University Belfast (QUB), Regional Virus Laboratory Belfast (RVL), Olink® proteomics (Uppsala, Sweden) or Genomics Medicine Ireland (GMI, Dublin, Dublin). This will require aliquots of plasma/serum or DNA to be transferred to the approved third party proteomic or genomic or service providers (such as QUB, Olink or GMI). In this event, all samples will be pseudo-anonymised. The codes relating to participant identification will not be disclosed to this study partner and remain in the custody of the chief investigator. Third party providers have already been approved as service providers with satisfactory evidence of encryption in storage and transfer of data and appropriate Material Transfer, Confidentiality and Intellectual Property agreements signed off by both the third party and the University. Unused DNA or plasma which is analysed by a third party such as GMI or Olink® proteomics will be destroyed. The research organisations that will use samples or data derived from analysis of samples could be not-for-profit e.g. universities or for-profit commercial companies (such GMI). GMI, however, have agreed to undertake: SNP genotyping, WGS and RNAseq generation analysis at no cost. Participant's name, address and personal details will not be made available to any organisation beyond the study team
Analysis
All sequencing, methylation and proteoomic analysis out sourced to Azenta (GeneWiz), Genuity and Olink Proteomics. Flow cytometry and 16s microbiome analysis will be completed at CTRIC.
