Sensibilidad y especificidad de los criterios diagnósticos DSM-5 en el trastorno del espectro autista en una muestra de niños y adolescentes españoles / Sensitivity and specificity of DSM-5 diagnostic criteria for autism spectrum disorder in a child and adolescent sample

Introducción Existe controversia acerca de los criterios DSM-5 para el diagnóstico de los trastornos del espectro autista (TEA). En la literatura encontramos resultados discrepantes, siendo el objetivo del estudio determinar la sensibilidad y la especificidad de los criterios DSM-5 para TEA en niños y adolescentes españoles. También se determinará la estabilidad del diagnóstico al pasar del DSM-IV-TR al DSM-5 y las diferencias clínicas entre TEA y trastorno de la comunicación social (TCS). Material y métodos El estudio se llevó a cabo en 2017, revisando las historias clínicas de los pacientes evaluados en nuestro servicio. Los ítems de la entrevista diagnóstica para el autismo (Autism Diagnostic Interview-Revised) se ajustaron al DSM-5 y se utilizaron para evaluar la sensibilidad y la especificidad de dicho manual. Resultados La sensibilidad del DSM-5 fue de 0,69-1,00, mayor para el género femenino, sin diferencias con respecto a la edad y menor para los pacientes con bajo funcionamiento. La especificidad fue de 0,64-0,73. Respecto a la estabilidad, el 83,3% de los casos de autismo diagnosticados con el DSM-IV-TR mantuvieron el diagnóstico siguiendo los criterios del DSM-5. En cuanto a las diferencias entre los pacientes diagnosticados de TEA y los diagnosticados de TCS, cabe mencionar que los primeros requirieron más tratamientos farmacológicos durante su evolución. Conclusiones Se necesitan más estudios centrados en el diagnóstico de TCS para determinar si la evolución es diferente a la de los pacientes diagnosticados de TEA. También será necesario confeccionar nuevas herramientas diagnósticas y terapéuticas para los pacientes con diagnóstico de TCS. (AU)

Background Controversy exists regarding the DSM-5 criteria for autism spectrum disorders (ASD). Given the mixed results that have been reported, our main aim was to determine DSM-5 sensitivity and specificity in a child and adolescent Spanish sample. As secondary goals, we assessed the diagnostic stability of DSM-IV-TR in DSM-5, and clinical differences between children diagnosed with an ASD or a social (pragmatic) communication disorder (SPCD). Methods This study was carried out in 2017, reviewing the medical records of patients evaluated in our service. Items from a parent report measure of ASD symptoms (Autism Diagnostic Interview-Revised) were matched to DSM-5 criteria and used to assess the sensitivity and specificity of the DSM-5 criteria and current DSM-IV criteria when compared with clinical diagnoses. Results DSM-5 sensitivity ranged from 0.69 to 1.00, and was higher in females. By age, the DSM-5 and DSM-IV-TR criteria showed similar sensitivity. In the case of intellectual quotient, DSM-5 criteria sensitivity was lower for those in the “low-functioning” category. DSM-5 specificity ranged from 0.64 to 0.73, while DSM-5 specificity was similar for all phenotypic subgroups. With respect to stability, 83.3% of autism disorder cases retained a diagnosis of ASD using the DSM-5 criteria. With regard to differences between ASD and SPCD, we found that patients diagnosed with ASD received more pharmacological treatment than those diagnosed with SPCD. Conclusions Further research is required to confirm our results. Studies focusing on the SPCD phenotype will be necessary to determine outcome differences with ASD and the most effective diagnostic and therapeutic tools. (AU)

Sensitivity and specificity of DSM-5 diagnostic criteria for autism spectrum disorder in a child and adolescent sample.

BACKGROUND: Controversy exists regarding the DSM-5 criteria for autism spectrum disorders (ASD). Given the mixed results that have been reported, our main aim was to determine DSM-5 sensitivity and specificity in a child and adolescent Spanish sample. As secondary goals, we assessed the diagnostic stability of DSM-IV-TR in DSM-5, and clinical differences between children diagnosed with an ASD or a social (pragmatic) communication disorder (SPCD). METHODS: This study was carried out in 2017, reviewing the medical records of patients evaluated in our service. Items from a parent report measure of ASD symptoms (Autism Diagnostic Interview-Revised) were matched to DSM-5 criteria and used to assess the sensitivity and specificity of the DSM-5 criteria and current DSM-IV criteria when compared with clinical diagnoses. RESULTS: DSM-5 sensitivity ranged from .69 to 1.00, and was higher in females. By age, the DSM-5 and DSM-IV-TR criteria showed similar sensitivity. In the case of intellectual quotient, DSM-5 criteria sensitivity was lower for those in the "low-functioning" category. DSM-5 specificity ranged from .64 to .73, while DSM-5 specificity was similar for all phenotypic subgroups. With respect to stability, 83.3% of autism disorder cases retained a diagnosis of ASD using the DSM-5 criteria. With regard to differences between ASD and SPCD, we found that patients diagnosed with ASD received more pharmacological treatment than those diagnosed with SPCD. CONCLUSIONS: Further research is required to confirm our results. Studies focusing on the SPCD phenotype will be necessary to determine outcome differences with ASD and the most effective diagnostic and therapeutic tools.

Adolescent Anorexia Nervosa: cognitive performance after weight recovery.

OBJECTIVE: Although there is no definitive consensus on the impairment of neuropsychological functions, most studies of adults with Anorexia Nervosa (AN) find impaired functioning in cognitive domains such as visual-spatial abilities. The objective of this study is to assess the cognitive functions in adolescents with AN before and after weight recovery and to explore the relationship between cognitive performance and menstruation. METHODS: Twenty-five female adolescents with AN were assessed by a neuropsychological battery while underweight and then following six months of treatment and weight recovery. Twenty-six healthy female subjects of a similar age were also evaluated at both time points. RESULTS: Underweight patients with AN showed worse cognitive performance than control subjects in immediate recall, organization and time taken to copy the Rey's Complex Figure Test (RCFT). After weight recovery, AN patients presented significant improvements in all tests, and differences between patients and controls disappeared. Patients with AN and persistence of amenorrhea at follow-up (n=8) performed worse on Block Design, delayed recall of Visual Reproduction and Stroop Test than patients with resumed menstruation (n=14) and the control group, though the two AN groups were similar in body mass index, age and psychopathological scale scores. CONCLUSION: Weight recovery improves cognitive functioning in adolescents with AN. The normalization of neuropsychological performance is better in patients who have recovered at least one menstrual cycle. The normalization of hormonal function seems to be essential for the normalization of cognitive performance, even in adolescents with a very short recovery time.
