A comparative study of inflammatory marker highly sensitive C- Reactive Protein in depression patients exhibiting suicidal behaviour and depression patients without suicidal behaviour

Abstract


Background: Recent research have found a link between inflammatory pathway and suicidal behaviour. hs-CRP, IL, TNF have been shown to have significant alterations in suicidality, however multiple covariates influence this relationship. One of the main limitations of most of the studies is that they have evaluated the CRP in patients demonstrating suicidal behaviour but not in depression. No study has been conducted in Indian subpopulation with parameters of our study. Aims of the study was to compare hsCRP levels between depression patients with suicidal behaviour and without suicidal behaviour.

Methods: Authors compared 50 depression patients with suicidal behaviour and 50 depression patients without suicidal behaviour, diagnosed using ICD10. Hamilton Depression Rating Scale (HDRS‑17), Suicide behaviour Questionnaire- Revised (SBQ-R), Beck Scale for Suicidal Ideation (BSSI) were applied for assessment of depression and suicidality. Highly sensitive CRP was measured using autoanalyzer.

Results: hsCRP levels were significantly high in depression patients with suicidal behaviour (4.12 mg/dl) than depression without suicidal behaviour (2.42 mg/dl). Duration of illness, HAM-D, BSSI and SBQ-R scores correlated positively with hsCRP levels.

Conclusions: Depression with suicidal behaviour patients have a significantly higher hs-CRP levels than depression without suicidal behaviour. Patients of depression with suicidal behaviour group have a strong positive correlation between hs-CRP levels and HAM-D, BSSI and SBQ-R scores.
