[Depressive disorder in Mexican pediatric patients with systemic lupus erythematosus (SLE)].

OBJECTIVE
To identify the prevalence of depression in Mexican pediatric patients with systemic lupus erythematosus.


MATERIALS AND METHODS
Analytical transversal study including patients aged 7-16 years with a diagnosis of systemic lupus erythematosus seen at the Pediatric Rheumatology Consultation Service. The disease was classified by means of the MEX-SLEDAI questionnaire. Descriptive statistics with central tendency and dispersion and comparative measurements with chi-squared and Mann-Whitney U tests. Logistic regression and association with odds ratios. SPSS v.21.0 statistical software package.


RESULTS
We evaluated 45 patients who presented depression, n=9 (20%), including eight females (89%) and one male (11%), median age 13 years (range, 7-16) in children with depression vs. 13 years (range, 9-14) p=0.941, depression more frequent in schoolchildren. Habitual residence, disease evolution time, and duration of the immunosuppressor did not show a significant difference between both groups. Divorced parents p=0.037. Neuropsychiatric manifestations of lupus presented in 2.2% of all patients and in 100% of patients with depression. Disease activity index (MEX-SLEDAI) did not demonstrate a relationship with the presence of depression.


CONCLUSION
Prevalences in pediatric populations are less that that reported in adults, association with disease activity, evolution time, and immunosuppressor use and duration not found.
