- INTRODUCTION: Hyperactivity of the hypothalamic-pituitary-adrenal (HPA)-axis is a common finding in major depressive disorder. Similar studies on suicide attempters are less abundant, and the results are divergent. The main aim of the present study was to investigate HPA-axis parameters by the time of a suicide attempt and at follow-up in search for associations between HPA-axis function and suicidal behavior. METHODS: Thirty-five suicide attempters and 16 non-suicidal controls were admitted to a psychiatric ward between the years of 1986 and 1992. Corticotrophin-releasing hormone (CRH) in cerebrospinal fluid and urinary cortisol were obtained for the suicide attempters. The patients were followed up approximately 12 years after the index admission. Cortisol was measured in saliva, and additional suicide attempts and current psychiatric symptoms were registered. RESULTS: At follow-up, evening salivary cortisol was lower in suicide attempters compared to controls. Low cortisol levels at follow-up were associated with severe psychiatric symptoms. Among women, repeated suicide attempts were associated with low morning and lunch salivary cortisol, and in this subgroup we also found significant correlations between salivary cortisol at follow-up, and CRH as well as urinary cortisol at index. CONCLUSION: We found evidence for an association between low HPA-axis activity and suicidal behavior. This could be due to long-lasting and severe psychiatric morbidity, which in turn has exhausted the HPA-axis of these patients. The potential role of hypocortisolism should be given more attention in studies on suicidal patients.

- The objective of this study was to investigate associations between suicidal intent and psychiatric symptoms, and to study the usefulness of the Suicidal Intent Scale (SIS) and the Comprehensive Psychopathological Rating Scale (CPRS) for suicide risk assessment in an inpatient population. One hundred and ninety-six suicide attempters, of whom 15 eventually committed suicide, were admitted to a psychiatric ward. They were assessed by means of the SIS and the CPRS. Cox regression analyses were performed in order to adjust the relationships between the individual CPRS subscales and suicide for age and gender. The patients who later completed suicide had higher scores on the CPRS than the patients who did not complete suicide. We found no associations between symptoms and suicidal intent. The severity of psychopathology, in terms of high CPRS scores, shows a stronger association with future suicide than the level of suicidal intent (SIS) among inpatient suicide attempters. Suicidal intent is evidently scored regardless of psychiatric symptoms.
