What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Doxycycline 7 daysDrug
Patient will be treated with doxycycline orally, 100 mg, bid, 7 days
Doxycycline 14 daysDrug
Patient will be treated with doxycycline orally, 100 mg, bid, 14 days
| Study group | Role | What they receive |
|---|---|---|
| erythema migrans patients treated with doxycycline | Experimental | adult patients with erythema migrans will be treated with oral doxycycline Receives: Drug: Doxycycline 7 days; Drug: Doxycycline 14 days |
What is being measured
The primary outcome is the main question the study is designed to answer.
inflammatory proteins in erythema migrans patients
The inflammatory immune profiles will be assessed using Luminex to measure the expression of cytokines and chemokines representative of innate and adaptive TH1, TH2, TH17, and B cell responses in serum and if available, skin, of patients during active infection and after treatment.
Measured: up to 12 months follow-up
Secondary outcomes (1)
gene polymorphisms in erythema migrans patients
ImmunoChip single-nucleotide polymorphism array for dense genotyping of rheumtic disease-relevant genomic variants will be used.
Measured: at enrollment

Questions about this trial
What is this clinical trial studying?
A study testing Doxycycline 7 days and Doxycycline 14 days in people with Erythema Migrans, run by University Medical Centre Ljubljana at 1 site in Slovenia.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 3 Nov 2020. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Slovenia. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
inflammatory proteins in erythema migrans patients (time frame: up to 12 months follow-up). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 3 Nov 2020.
