Clinical trials
1 of the 629 ClinicalTrials.gov records in the tracker snapshot (taken 2026-10-07) match Lyme / PTLDS (1 via keyword match). 1 are recruiting, not yet recruiting, enrolling by invitation or active; 0 list a 2026 start date and 1 had their registry record updated in 2026. Median planned or actual enrollment is 120 participants (1 trials report a figure).

Therapeutic agents catalogue
The OSMF therapeutic-agents catalogue lists 4 agents with Lyme as a primary condition (of 605 agents overall). Evidence level is the catalogue's own coarse grading, assigned automatically from the number and type of linked studies and trials; it is not a GRADE assessment.

Biomarkers catalogued
The Lyme / PTLDS biomarker atlas (last edited 2026-06-29) holds 36 marker entries across 7 categories, citing 5 distinct DOIs: 23 reported elevated, 2 reduced and 11 with mixed or inconsistent findings. Direction is relative to the comparison group in the cited source (usually healthy controls) and a single entry can rest on one study.
| Category | Elevated | Reduced | Mixed | Total |
|---|---|---|---|---|
| Serologic | 9 | 0 | 0 | 9 |
| CSF | 4 | 0 | 2 | 6 |
| Inflammatory | 4 | 0 | 2 | 6 |
| Molecular | 1 | 0 | 3 | 4 |
| Co-infection | 4 | 0 | 0 | 4 |
| Chronic/PTLDS | 0 | 1 | 3 | 4 |
| Functional | 1 | 1 | 1 | 3 |

Research cohorts
1 of the 32 cohorts in the OSMF post-acute infection syndrome (PAIS) cohort database relate to Lyme / PTLDS, together enrolling about 234 participants where a figure is recorded. This is a curated database, not a systematic census of cohorts.
| Cohort | Design | Enrolled | Biobank | Registration |
|---|---|---|---|---|
| Johns Hopkins SLICE early-Lyme cohort (Aucott/Rebman) | prospective inception | 234 | active | — |
Methods
This page was generated by scripts/build_reports.py on 7 October 2026 from the data snapshot described below. No number is entered by hand.
- Studies. Records in
data/lyme.json(source: PubMed (NCBI); feed last updated 2026-07-08) whosepub_dateparses to a date in 2026. Year-only or year-month dates are mapped to the first day of the period. 0 record(s) had no parseable date and were excluded. Monthly counts bin by publication month; journal counts use the record's journal string verbatim (no normalisation of abbreviations). - Trials. Records in
data/clinical_trials/clinical_trials_current.json(snapshot 2026-10-07). A trial matches when itsmapped_conditionscontains no curated label (none defined), or when its title or raw condition list matches the pattern(s) /\blyme\b/i, /borreli/i, /\bptlds\b/i. Status, phase and sponsor type are the registry's own fields, counted once per trial. "Started in 2026" usesstart_date; "updated in 2026" useslast_updated. Agents are the tracker's normalised intervention names; a trial with several agents counts once for each. Median enrollment uses the registryenrollmentfield (actual or estimated) where numeric. - Agents catalogue. Entries in
data/therapeutic_agents.json(updated 2026-10-07) whose "Primary Conditions" includes 'Lyme', grouped by the catalogue's "Evidence Level" string. - Biomarkers. Entries in
data/biomarkers/lyme.json, grouped bycategoryanddirection(up, down, mixed). Distinct DOIs count uniquereference.doivalues. - Cohorts. Entries in
data/pais-cohorts-index.json(version 2.0.0-seed) whosepathogen_idis in ['borrelia-burgdorferi'].
Limitations
- The literature feed is a bounded, rolling PubMed query result. It captures recent indexing activity, not the full year, and PubMed indexing dates lag print publication. Counts here will not match a systematic search.
- Study counts measure volume, not quality. No screening for study design, sample size, peer-review status or relevance beyond the search query was applied.
- Trial matching depends on the tracker's condition mapping and keyword patterns; trials registered under umbrella terms (for example "post-viral fatigue") may be missed, and registry status fields are frequently stale.
- Biomarker direction reflects what each cited source reported, often from a single cohort; "elevated" in one study does not imply replication.
- The cohort database and agents catalogue are curated and incomplete, and the evidence-level grading is automatic and coarse.
- Different sections rest on different snapshot dates (feed 2026-07-08, trials 2026-10-07, biomarkers 2026-06-29, agents 2026-10-07).
- This is a year-to-date report; it is regenerated daily and will change until 31 December 2026.
