Abstract
Objective
This study investigates MMP-9 enzyme levels in patients who attempted suicide by taking high doses of drugs, considering their sociodemographic characteristics.
Methods
The study included 45 patients who attempted suicide by high-dose drug intake admitted to the emergency room and 45 healthy volunteers with no neuropsychiatric disorders. Blood samples were collected to measure MMP-9 levels, and informed consent was obtained. The samples were centrifuged and analyzed using the ELISA method, with results statistically compared.
Results
Findings indicate that being single and a student significantly increased suicide tendencies (p = 0.002 and p = 0.001, respectively). Psychiatric disorders were the most common cause at 40.0%, followed by antidepressants (55.6%), analgesics (20.0%), and antidiabetics (8.9%) as the most used drugs for suicide. MMP-9 levels were significantly higher in patients who attempted suicide compared to controls (83.74 (±7.14) ng/mL vs. 54.97 (±12.27) ng/mL, p = 0.001). Additionally, MMP-9 levels were higher in single patients compared to married or divorced individuals (p = 0.008). MMP-9 levels were lower in patients with psychiatric disorders, recent psychiatric services, family history of psychiatric disorders, and previous suicide attempts (p = 0.014, p = 0.046, p = 0.035, p = 0.034).
Conclusions
This study shows MMP-9 enzyme can be a potential biomarker for drug-induced suicide attempts, emphasizing the importance of evaluating MMP-9 levels to assess suicide risk and develop prevention strategies.
期刊介绍:
Founded in 1961 to report on the latest work in psychiatry and cognate disciplines, the Journal of Psychiatric Research is dedicated to innovative and timely studies of four important areas of research:
(1) clinical studies of all disciplines relating to psychiatric illness, as well as normal human behaviour, including biochemical, physiological, genetic, environmental, social, psychological and epidemiological factors;
(2) basic studies pertaining to psychiatry in such fields as neuropsychopharmacology, neuroendocrinology, electrophysiology, genetics, experimental psychology and epidemiology;
(3) the growing application of clinical laboratory techniques in psychiatry, including imagery and spectroscopy of the brain, molecular biology and computer sciences;
