NCT03611166

Brief Summary

Following severe traumatic brain injury, patients may remain unconscious for many years. It is the first proteomic analysis comparing differentially expressed proteins between patients with chronic disorder of consciousness and controls so far. The investigators generated accurate lists of proteomes and identified differences at different disease time courses. The obtained results provide new insight into understanding the molecular mechanisms underlying the chronic disorder of consciousness.

Outcome Measures

Primary Outcomes (1)

  • Protein profiling

    A coupled isobaric tag for relative and absolute quantitation (iTRAQ)-based proteomics approach was used to screen differentially expressed proteins (DEPs) between patients and controls.

    Three months

Secondary Outcomes (2)

  • Glasgow Outcome Scale (GOS)

    In one year

  • Coma Recovery Scale-Revised(CRS-R)

    30 minutes before blood collection

Eligibility Criteria

Healthy VolunteersYes
Age GroupsChild (0-17), Adult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

Patients with chronic disorder of consciousness were recruited at the rehabilitation units of Hangzhou Wujing Hospital (Hangzhou, Zhejiang, China).

You may qualify if:

  • Patients ages 14 to 65 years old;
  • Patients had a history of sTBI;
  • Patients had awakened from a coma (indicating preserved sleep-wake cycles), including vegetative state and minimally consciousness state;
  • Patients stay unconscious for more than 1 month.

You may not qualify if:

  • Patients with acute infectious diseases or liver dysfunction;
  • Patients with serious diseases such as cardiac or pulmonary problems.

RECRUITING

Biospecimen

Retention: SAMPLES WITHOUT DNA

Peripheral blood (5 mL) was collected in a Vacutainer® tube, containing anticoagulant, using standardized phlebotomy procedures. Plasma was prepared by centrifugation (2,000 g, 5 min, 4°C) and stored at -80°C until further analysis.
