| Abstract |
Biomarkers are now widely used in many fields of medicine, and the identification of biomarkers that predict antipsychotic efficacy and adverse reactions is a growing area of psychiatric research. Monoamine molecules of the peripheral bloodstream are possible prospective biomarkers based on a growing body of evidence indicating that they may reflect specific changes in neurotransmitters in the brain. The aim of this study was to detect peripheral biogenic amine indicators of patients with acute psychosis and to test the correlations between the biological measures studied and the psychopathological status of the patients. This research included 60 patients with acute psychosis treated with olanzapine (n = 30) or haloperidol (n = 30). Here, we measured biogenic amine indicators, including mRNA levels of dopamine receptor D4 (DRD4) and the serotonin 2A receptor (5HTR2A), in peripheral blood mononuclear cells (PBMCs) using quantitative real-time polymerase chain reaction and serum dopamine concentrations by enzyme linked immunosorbent assay (ELISA). Psychopathological status was evaluated using psychometric scales. The assessments were conducted prior to and after 14 and 28 days of treatment. The administration of haloperidol, but not olanzapine, up-regulated 5HTR2A mRNA in a linear manner, albeit without statistical significance (p = 0.052). Both drugs had non-significant effects on DRD4 mRNA levels. Nevertheless, a positive correlation was found between DRD4 and 5HTR2A mRNA levels over a longitudinal trajectory, suggesting co-expression of the two genes. A significant positive correlation was observed between 5HTR2A mRNA levels and total Positive and Negative Syndrome Scale (PANSS) scores in both groups of patients before treatment. A significant correlation between baseline 5HTR2A mRNA levels and PANSS scores on days 14 and 28 of treatment remained for patients treated with olanzapine only. Moreover, a significant positive correlation was observed between blood serum dopamine levels and scores on extrapyramidal symptom scales in the olanzapine group. The DRD4 and 5HTR2A genes are co-expressed in PBMCs during antipsychotic administration. Despite a correlation between the studied biogenic amine indicators and the psychopathological status of patients, reliable biomarkers of treatment response could not be determined. |

Attention Score in Context
This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 10 December 2017.
All research outputs
#18,578,649
of 23,011,300 outputs
Outputs from BMC Psychiatry
#3,938
of 4,746 outputs
Outputs of similar age
#327,466
of 439,767 outputs
Outputs of similar age from BMC Psychiatry
#62
of 76 outputs
Altmetric has tracked 23,011,300 research outputs across all sources so far. This one is in the 11th percentile – i.e., 11% of other outputs scored the same or lower than it.
So far Altmetric has tracked 4,746 research outputs from this source. They typically receive a lot more attention than average, with a mean Attention Score of 11.9. This one is in the 10th percentile – i.e., 10% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 439,767 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 14th percentile – i.e., 14% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 76 others from the same source and published within six weeks on either side of this one. This one is in the 10th percentile – i.e., 10% of its contemporaries scored the same or lower than it.
