RESUMO
BACKGROUND: Abnormal activity of two enzymes relevant to neurodevelopment, namely nuclear-distribution element-like 1 (Ndel1) and angiotensin I-converting enzyme (ACE), was reported in individuals with schizophrenia; to our knowledge, these oligopeptidases were never measured in bipolar disorder (BD). AIMS: Evaluate the enzyme activity of Ndel1 and ACE in euthymic individuals with BD type 1 which was compare to healthy control (HC) group. METHODS: Ndel1 and ACE activities were assessed in the serum of individuals with BD type 1 according to DSM-IV criteria (nâ¯=â¯70) and a HC group (nâ¯=â¯34). The possible differences between BD type 1 and HC groups were evaluated using Analysis of Covariance (ANCOVA), and the results were adjusted for age, gender and body mass index. RESULTS: We observed a positive correlation between Ndel1 activity and the total YMRS score in BD group (pâ¯=â¯0.030) and a positive correlation between ACE activity and Ham-D score (pâ¯=â¯0.047). ANCOVA analysis showed lower Ndel1 activity in BDs compared to HCs. Interestingly, we did not observe between-groups differences in ACE activity, despite the recognized correlation of ACE activity levels with cognitive functions, also described to be worsened in psychiatric patients. CONCLUSION: Oligopeptidases, especially Ndel1, which has been strongly correlated with neurodevelopment and brain formation, are potentially a good new target in the study of the neurobiology of BD. LIMITATIONS: The relatively small sample size did not permit to examine the cause-effect relationship of clinical dimensions of BD and the enzymatic activity.

INTRODUCTION: In order to address the mental health problems of the Colombian population it is necessary to have diagnostic tools (local and international) that are valid, easy to apply, and comparable. OBJECTIVE: To compare the sensitivity and specificity between the CIDI 3.0 and the SCID-I for major depressive disorder, bipolar I and II disorder, and substance dependence disorder. METHODOLOGY: Cross-sectional study comparing the life prevalence of three mental disorders in 100 subjects using the CIDI 3.0 and the SCID-I. The study was approved by the Institutional Ethics Committee. The two diagnostic interviews were performed that measured by sensitivity, specificity, positive predictive value and negative predictive value with confidence intervals of 95%. The SPSS version 21.0 software was used for data analysis. RESULTS: The median age was 43.5 years, with an interquartile interval of 30 years. The highest sensitivity (Se) and specificity (Sp) was observed for drug dependence diagnosis - with 80%, (95%CI, 34.94-100), and 98.46 (95%CI, 94.7-100), respectively. CONCLUSIONS: SCID-I and CIDI 3.0 showed different levels of sensitivity and specificity for the three disorders studied with: high for substance dependence disorder, moderate for bipolar disorder I and II, and low for major depressive disorder.

Introducción: El abordaje de los problemas de salud mental de la población colombiana hace necesario disponer de instrumentos diagnósticos válidos, fáciles de aplicar y comparables (local e internacionalmente). Objetivo: Comparar la sensibilidad y la especificidad diagnóstica entre el CIDI 3.0 y el SCID-! para el trastorno depresivo mayor, el trastorno afectivo bipolar I y II y el trastorno por dependencia de sustancias. Metodología: Estudio transversal que comparó en 100 sujetos las prevalencias de vida de tres trastornos mentales por medio del CIDI 3.0 y el SCID-I. La investigación fue aprobada por el Comité de Ética Institucional. Se midieron la sensibilidad, la especificidad, el valor predictivo positivo y el valor predictivo negativo (con sus respectivos intervalos de confianza del 95%) de las dos entrevistas diagnósticas. Para el análisis de la información se utilizó el software SPSS® versión 21.0. Resultados: La mediana de edad fue 43,5 [intervalo intercuartílico, 30] anos. La sensibilidad (Se) y la especificidad (Es) más altas se observaron en el diagnóstico de trastorno por dependencia de drogas -Se, 80% (IC95%, 34,94%-100%); Es, 98,46% (IC95%, 94,7%-100%)-. Conclusiones: El SCID-I y el CIDI 3.0 mostraron diferentes niveles de sensibilidad y especificidad para los tres trastornos estudiados así: altas para el trastorno por dependencia de sustancias, moderadas para el trastorno afectivo bipolar I y II y bajas para el trastorno depresivo mayor.
