Inflammatory Parameters in Patients with Suicide Attempts by Drug Overdose: A Comparative Study with a Comparison...

Area of Science:

• Psychiatry
• Immunology
• Biochemistry

Background:

• The link between psychiatric conditions and systemic inflammation is not fully understood.
• Inflammation may contribute to the biological basis of suicidal behavior.

Purpose of the Study:

• To examine the association between inflammatory markers and hemogram-derived indices in suicide attempt survivors.
• Focus on patients who attempted suicide via oral drug overdose.

Main Methods:

• Retrospective comparative study of 343 suicide attempters and 421 healthy controls.
• Analyzed C-reactive protein (CRP), albumin, complete blood count, and derived indices like CAR, NLR, SIII, PLR, and MLR.

Main Results:

• Suicide attempters showed higher CRP, leukocyte, neutrophil, and monocyte levels.
• Elevated CAR, NLR, SIII, and MLR were observed in attempters; PLR did not differ.
• CAR demonstrated the highest discriminative ability for suicide attempts via ROC analysis.

Conclusions:

• Hemogram-derived inflammatory indices, particularly CAR, are significantly associated with suicide attempts.
• These accessible biomarkers may offer insights into suicide risk assessment.
• Further prospective research is required to validate these findings.
