Why
  1. The study's listed conditions name Sepsis, a narrower term within Systemic Inflammatory Response Syndrome.
Confidence
High: the new condition is named in the study's own listed conditions. Of 351 hand-checked studies reclassified this way, 68% were exactly right and 84% in the right disease family; the registry's first term was right for 5% (measured 2026-10-21). How we classify →

Study summary

The aim of the study is to measure serum levels of myristic acid in septic patients and to compare them with myristic acid serum levels in patients with Systemic Inflammatory Response Syndrome of non infective etiology and in healthy volunteers. Furthermore, other biomarkers of sepsis are evaluated in comparison with microbiological findings detected either by standard hemocultures or by molecular biological methods.

Read the detailed description

Currently, there is an array of biomarkers potentially useful in diagnosis and prognosis in septic patients, either alone or in combination. Only a fraction of them is used in clinical practice. The reasons vary, low sensitivity or specificity is the main one, cost/benefit or difficult processing with the need of highly specialized laboratory to name the other.

Recent pilot study from Swedish authors (A.M.Kauppi et al.) published in 2016 showed high correlation of myristic acid levels in blood in patients with sepsis and bacteraemia. There was no other publication on this molecule in relation to sepsis before. Cambiaghi et al. observed its significant decrease in nonresponders to the treatment of septic shock.

Myristic acid is an organic acid of linear structure. Measurement of its level will be performed using gas chromatography linked with mass spectrometry.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Oct 2017 to primary completion in Dec 2021, 50 months.

Of 492 non-industry observational studies under Sepsis, half reached primary completion within 29 months of starting (the median), counting those still running; a quarter within 13 and three quarters within 58. This study's 50 months is above that.

Counting every sponsor, half of 544 studies reached it within 27 months; a quarter within 12 and three quarters within 56.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Feb 14, 2023, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
