Q: Does the creatinine clearance measurement have to be taken within the last 3 months?
A: Previously, this was a requirement in REDCap, however this has now been changed to the last measurement taken.
 
Q: When should Patient Baseline Data be completed?
A: Patient Baseline Data should be completed immediately after the patient has consented to participate in the study. This form contains critical information on eligibility criteria and informed concent, so we ask this is filled out as early as possible.
 
Q: Should the study staff or the patient complete the questionnaire?
A: The questionnaire should be completed by the study staff.
 
Q: Is a print version of the questionnaire available?
A: A print version of the questionnaire can be found at the website (https://chip.dk/Research/Studies/MISTRAL/Study-documents) together with many other study documents.
 
Q: Can blood samples be taken before the patient has given a stool sample?
A: No, the patient must deliver a stool sample before blood is taken. As the primary aim of this study is to investigate microbiome related factors associated with serious AIDS and non-AIDS events, collection of the faecal sample is of utmost importance. Stool samples should be returned to the lab within 48 hours of defacation and blood samples can be taken after the stool sample has been returned.
 
Q: Must the patient take home the stool kit and do the stool sample at home?
A: Not necessarily. If possible, the stool sample can be taken the day of the visit, as long as the patient has given consent to participate in the study beforehand.

Q: A participant consents and takes the stool sample collection kit home with them, when do they have to return?
A: The participant has to return to the clinic with their stool sample within 48 hours of defacation. This should occur as early as possible to the consent, to ensure eligibility criteria are still met at time of sample collection. However, we allow up to 3 months from date of concent for the participant to collect the stool and return the sample to the clinic.
