Registration Number

Lead Sponsor
Zealand University Hospital
Brief Summary

The COVID-19 infection affects humans differently. While some recover quickly and fully, others develop serious illnesses and late complications. The term late complications describe symptoms that last for 12 weeks or longer after COVID-19 infection is detected. The aim of the present project is to investigate whether it is possible to identify genetic factors that occur more frequently in people suffering from COVID-19 late complications than in those who do not develop late complications. The investigators aim to develop a genetic profile that identifies individuals at high risk for late complications of COVID-19. Number and nature of late complications will be analysed to identify patterns in the incidence of late complications associated with certain genetic traits. The study is designed as a case-control study and is expected to include 500 subjects between 18 and 65 years of age who at least 12 weeks ago tested positive for COVID-19; 250 who suffer from late complications and 250 who have fully recovered.

Primary Outcome Measures
NameTimeMethod
DyspneaAt inclusion

Measured by means of Medical Research Council Dyspnoea Scale (MRC), which is a single-item, rated on a 5-point likert-scale in the range 1 to 5, with higher scores indicating worse symptoms.

Secondary Outcome Measures
NameTimeMethod
Ability to copeAt inclusion

Measured by means of Coping Orientation to Problems Experienced Inventory (Brief COPE), a 28-items self-report questionnaire, scored on a 4-point Likert scale from 1 (I haven't been doing this at all) to 4 (I've been doing this a lot). The total score is in the range 28-112.

Hand grip strength (HGS)At inclusion

Measure the maximum isometric strength in the hand and forearm.

Psychic stressAt inclusion

Measured by means of Kessler Psychological Distress Scale (K10), a 10-item questionnaire, scored on a 5-point Likert scale from 1 (None of the time) to 5 (All the time). The total score is in the range 10-50.

Cognitive impairmentAt inclusion

Measured by means of Symbol Digit Modalities Test (SDMT). The score is the correct number of substitutions in 90 s, and is in the range 0-110.

Level of Personality FunctioningAt inclusion

Measured by means of Level of Personality Functioning Scale - Brief Form (LPFS-BF), a 12-item self-report questionnaire, scored on a 4-point Likert scale from 1 (completely untrue) to 4 (completely true). The total score is in the range 12-48.

Physical and mental healthAt inclusion

Measured using the 12-point Short Form Health Survey (SF-12).

Work RehabilitationAt inclusion

Measured by means of Work Rehabilitation Questionnaire (WORQ).

Sexual function assessed by Female Sexel Function Index (FSFI_R)At inclusion

Measured by means of Female Sexel Function Index (FSFI_R) for women. FSFI-R is a 7-item self-report questionnaire, scored on a 5-point Likert scale from 1 to 5 .

Sexual functionAt inclusion

Measured by means of International Index of Erectile Function (IIEF-5) for men . IIEF-5 is a 5-item self-report questionnaire, scored on a 5-point Likert scale from 1 to 5.
