RESUMEN
Inflammatory processes are associated with mood disorders, but data on pediatric patients are scarce. The aim of this study was to investigate a possible association between elevated neutrophil/lymphocyte ratio (NLR) - a marker of inflammation and mood polarity (manic/depressed) in adolescents, admitted between 2010 and 2015 due to a mood disorder episode and to an adolescent inpatient ward. Electronic medical records of 305 patients (aged 10-19 years, 60.6% males) admitted during the study period due to a mood disorder episode were reviewed. Of these, 63 were diagnosed with manic episodes and 242 with depressive episodes. Multivariate analyses were used to compare NLR between and within the two groups, covarying for age, sex, and antipsychotic use. NLR was significantly higher in the manic episode group compared with the depression one. Moreover, in inpatients with multiple hospitalizations, the NLR was higher during their manic episodes than that during their nonmanic states. These results suggest that, as has been reported in adults with bipolar disorder, inflammatory mechanisms may be involved in adolescents' mood disorders as well, particularly in the manic episodes. Thus, clinicians may consider adding anti-inflammatories as part of the treatment of these patients.

OBJECTIVE: Deliberate self-harm (DSH) is a major health concern among adolescents, and is often associated with the need for inpatient psychiatric hospitalization. The aim of this study was to identify clinical and demographic characteristics associated with DSH behavior among adolescents admitted to an acute psychiatric inpatient unit. METHOD: We retrospectively analyzed data from the electronic medical records of consecutive admittances to a single acute adolescent inpatient unit (n = 703, mean age 15.2). We compared inpatients with DSH to inpatients without DSH and further compared within the DSH group based on the presence of suicidal intent. RESULTS: Compared to Non-DSH inpatients (n = 497), youths admitted following DSH (n = 206) were more likely to be female (OR = 2.6, 95%CI 1.7-4), currently in depressive exacerbation (OR = 2.4, 95%CI 1.6-3.6), with concurrent suicidal ideation (OR = 3.9, 95%CI 2.5-5.9), and history of alcohol use (OR = 5.6, 95%CI 3.2-9.5). Within DSH youths, no significant clinical differences were identified between those admitted following a suicide attempt (n = 102) compared to non-suicidal-self-injury (n = 104), who were generally younger. CONCLUSIONS: Findings suggest that early detection and intervention of DSH and depressive crisis is warranted, regardless of the self-harm subtype.HIGHLIGHTSDeliberate self-harm is common among adolescent psychiatric inpatients.Adolescent inpatients with deliberate self-harm are predominantly females with concurrent depression and suicidal ideation.We did not detect significant clinical and demographic differences between self-harmers with or without suicidal intent.

Accumulating data suggest an association between inflammation and schizophrenia and related psychosis. While several studies have established this immune-psychosis association in adult schizophrenia patients, there is very limited data associating inflammation with acute psychosis in children and adolescents. The ratio between neutrophils and lymphocyte, computed from routine blood counts, has been shown to correlate with traditional markers of inflammation, and is therefore considered a proxy-marker for inflammation. Here we report elevated neutrophil to lymphocyte ratio and total leukocyte count in psychotic adolescent inpatients (n = 81, mean age 14.7 years, 52% males) compared to non-psychotic adolescent inpatient (n = 285, mean age 15.9 years, 58% males), in a population of adolescent inpatients with no affective symptomatology. The elevated neutrophil to lymphocyte ratio remained significant after controlling for confounders such as age, BMI, smoking and antipsychotic medication. In a subset of psychotic adolescent inpatients (n = 20, mean duration between blood test 157 days), we found significant decrease in neutrophil to lymphocyte ratio at clinical remission compared with the acute psychotic state. The results suggest that psychosis is associated with peripheral markers of inflammation early in the course of psychiatric pathology, and that inflammation may represent a state that accompanies psychosis and decreases during clinical remission.
