NCT02322918

Brief Summary

The purpose of this study is to determine if candidate polymorphisms in brain-derived neurotrophic factor (BDNF) and catechol-o-methyl transferase (COMT) are predictive of psychosis disorder severity, symptomology, and resolution in patients at BCPP. A secondary objective will be to form a biorepository of blood and saliva samples from patients at BCPP so that further genetic, proteonomic and pharmacogenomic studies may be done to gain insight into the genetic basis of differences in psychosis disorder presentation and manifestation, and differences in response to antipsychotic drug treatment.

Outcome Measures

Primary Outcomes (1)

  • Creation of biorepository of blood samples for future genetic, proteonomic and pharmacogenomic studies.

    A biobank of stored samples will be used to determine the genetic variability in psychosis disorder.

    One visit during participant's stay at BCPP, an expected average of 6 months

Secondary Outcomes (2)

  • Identification of single-nucleotide polymorphisms (SNPs) in the BDNF and COMT genes

    One visit during participant's stay at BCPP, an expected average of 6 months

  • Medical Chart Review

    One visit during participant's stay at BCPP, an expected average of 6 months

Study Arms (1)

Participants admitted to BCPP

Blood or saliva samples will be collected from participants for whole genomic/transcriptomic sequencing

Genetic: Blood samples for whole genomic/transcriptomic sequencing

Interventions

Participant will receive one blood draw whereby two samples will be extracted. If the participant wishes to participate in the study but is fearful of needles, they may be given the option to provide a saliva sample. A retrospective medical chart review will be performed after participant is discharged from BCPP in order to obtain a full phenotype. Genotyping of BDNF and COMT will be performed. Protein levels of BDNF will be determined. The remaining blood or saliva samples will be stored over the long-term in a biorepository at the BC Mental Health and Addictions Research Institute. A retrospective medical chart review will be completed after the participant is discharged.

Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

The population will include all patients who have been admitted to the British Columbia Psychosis Program (BCPP). BCPP provides intensive inpatient care for individuals who have psychosis-related treatment challenges, including pharmacologic, biophysical, and psychosocial services. Admission criteria to BCPP include the following: 1) Must be 18 years or older; 2) Diagnosis of schizophrenia, schizoaffective disorder, mood disorder with psychosis; 3) History of no response or inadequate response of positive symptoms to at least 2 adequate trials of antipsychotics (one of which is a second generation agent) by health authority tertiary clinical teams; 4) Incomplete recovery of social, vocational, and occupational functioning and 5) If present, substance use disorder, pervasive developmental disorder, developmental disability, personality disorder, aggression, or head injury are not the primary focuses of treatment.

You may qualify if:

  • Admission to BCPP.
  • Has provided written informed consent.

You may not qualify if:

  • None.
