Collection:

Collection ID:CO001460
Collection Summary:Sera (both cohorts) were collected at the time of diagnosis (baseline); at the completion of antibiotic therapy, approximately two to three weeks following diagnosis (post-treatment); and at one-year post-treatment (one-year follow-up). PTLDS (symptoms) patients were classified as such if symptoms developed at or within 6 months following diagnosis and persisted for at least 6 months following the completion of antibiotic therapy. Patients were classified as PTLDS (syndrome) if they met the above criteria and with daily life functional impairment reported.
Sample Type:Blood (serum)

Treatment:

Treatment ID:TR001480
Treatment Summary:N/A

Sample Preparation:

Sampleprep ID:SP001473
Sampleprep Summary:Serum samples were randomized prior to extraction of small molecule metabolites and LC-MS analyses. Metabolites were extracted with 75% methanol as previously described. Extracted metabolites were analyzed by LC-MS.

MS Comments:LC-MS data were processed with MassHunter Profinder version B.08.00 and Mass Profiler Professional version B.14.9.01 (Agilent Technologies) to identify differentiating molecular features (MFs; metabolites defined by a retention time and accurate mass) between PTLDS and non-PTLDS patients at baseline, post-treatment and one-year follow-up in cohort-one. The biosignature-MFs determined using cohort-one were targeted in patient samples from cohort-two using MassHunter Profinder.
