Summary

Analysis of the relationship between clinical characteristics and haematological parameters in long COVID.

The novel coronavirus (Covid19) pandemic declared by the World Health Organisation in March 2020 has had an enormous huge impact upon health, health systems and society. Early research has focused on the acute illness caused by the virus. It is now clear that significant numbers of patients infected with Covid19 continue to suffer with multiple, often severe, unexplained symptoms for months after initial infection, so-called long-Covid.

Long-Covid symptoms are typically multi-system in their presentation comprising constitutional changes (e.g. fever and fatigue), neuropsychiatric disturbance (e.g. anxiety, insomnia and brain fog), neurosensory symptoms (e.g. headaches and pins and needles), cardiorespiratory effects (e.g. breathlessness and chest pain), gastrointestinal dysfunction (e.g. diarrhoea and food intolerances) and dermatological changes (e.g. rashes and vascular changes).

The objectives of this observational, cross-sectional, case-control study are to describe long-Covid clinical phenotypes and to explore whether clinical symptom presentations correlate with haematological and other inflammatory blood abnormalities that might shed insight into underlying pathogenic mechanisms.

The study will require the participation of long-Covid patients, seen in an outpatient setting at The Physicians' Clinic, and will correlate clinical symptom phenotypes with laboratory parameters we believe might be relevant to long-Covid. Recruitment of asymptomatic patients, who have recovered from Covid19 infection, will provide a control patient group. Eligible patients will be sent a patient information sheet, describing the study objectives and protocol, inviting them to participate in the study and seeking consent for their participation, which will require analysis of their \[anonymised\] clinical and laboratory data. Clinical information will be retrieved from patient case records and patients will be asked to complete a symptom questionnaire. All patients will require one blood sample to be taken which will typically form part of their clinical care. Recruitment will occur over a 6 month period.
