Comparison Between Inflaininatory Biomarkers (High-Sensitivity C-Reactive Protein And Neutrophil-Lymphocyte Ratio) And Psychological Morbidity In Suicide Attempt Survivors Brought To Medicine Emergency

Objectives: This study aimed to compare inflammatory biomarkers (high-sensitivity {hs} C-reactive protein, neutrophil-lymphocyte ratio) and psychological morbidity in suicide attempt survivors.Methods: One hundred ninety-eight poisoning cases screened, 40 age-matched suicide attempt survivors (SAS), 40 healthy controls (HC) between the age of 18 years and 60 years were included. Complete hemogram, neutrophil-lymphocyte ratio (NLR), hsCRP values obtained, compared with Hospital Anxiety and Depression Scale (HADS), suicide intent scale, presumptive stressful life events scale (PSLES), general health questionnaire 12-item (GHQ-12) (Hindi version), and Hindi Mental State Examination (HMSE).Results: A statistically significant difference was observed in hsCRP (p=0.016) and NLR (p=0.029) of depressed-suicidal participants vs healthy controls. hsCRP values of anxious-suicidal subjects vs healthy controls showed a statistically significant difference (p=0.001). There was a statistically significant difference between patients, healthy controls in HADS anxiety and HADS depression mean scores (p<0.001). The PSLES items were ranked according to the mean stress scores of all the items (mean +/- SD), highest four were excessive alcohol use by the family member 47.50 (+/- 27.03), conflicts with in-laws 50 (+/- 27.73), family conflict 50 (+/- 29.42), marital conflict 50.63 (+/- 32.76). There was a statistically significant difference in hemoglobin (p<0.001), red blood cells count (p<0.001), hematocrit (p<0.00 I) between suicide attempt survivors and healthy controls.Conclusion: Both hsCRP and NLR have emerged as potential inflammatory biomarkers for depressive patients with suicidal attempts. Additionally, there may be a link between anemia and suicide risk in patients with depression.
