[Correlations between thrombodynamic parameters of coagulation and negative syndromes in patients with schizophrenia].

OBJECTIVE

To identify a possible correlation between parameters of thrombodynamic coagulation and negative syndromes in patients with schizophrenia.

MATERIAL AND METHODS

The study included 148 female inpatients, aged 16 to 57 years, with the following mental disorders: schizophrenia with attack-like/attack-progressive/continuous type of course (F20.00-2), schizotypal disorder with affective fluctuations (F21.3-4). The thrombodynamics test (TD) was carried out on a T-2 thrombodynamics recorder (Hemacore LLC, Moscow, Russia).

RESULTS

A positive correlation was shown between the thrombodynamic parameters of clot growth rates (V, Vst, and Vi), clot size at the 30th minute (CS), and the total severity of negative syndromes (PANSS). There is a negative correlation between the time of spontaneous clots (Tsp) and the total severity of negative syndromes in patients. Positive correlations of V and Vst with scores on the fourth (Passive/apathetic social withdrawal), fifth (Difficulty in abstract thinking) and seventh (Stereotyped thinking) items of the PANSS negative subscale were revealed. There is a negative correlation between Tsp and the score on the 7th item, i.e. a shorter time for the appearance of spontaneous clots corresponds to a more pronounced Stereotyped thinking in patients.

CONCLUSION

For the first time, correlations between thrombodynamic indicators of hypercoagulation and negative syndromes in patients with schizophrenia are identified, which emphasizes the need to normalize hemostasis to prevent further aggravation of these disorders.
