Antecedentes

El valor de la biopsia renal en niños con síndrome nefrótico sigue siendo controvertido, especialmente en pacientes con recaídas frecuentes y corticodependientes antes de administrar inmunodepresores.

Métodos

Hemos enviado una encuesta sobre el síndrome nefrótico a todos los nefrólogos infantiles españoles que son miembros de la Asociación Española de Nefrología Pediátrica. La encuesta consta de 7 preguntas acerca de la utilidad de la biopsia en las distintas circunstancias de la enfermedad.

Resultados

La tasa de respuestas a la encuesta fue del 50%. Un 85% de los encuestados utiliza los mismos criterios diagnósticos. En cuanto a la indicación de biopsia renal en la enfermedad, el 85% considera necesario hacerla en caso de el 85% considera necesario hacerla en caso de resistencia al tratamiento con esteroides. El 57,7% recomienda la biopsia en corticodependientes y recaídas frecuentes antes del tratamiento inmunodepresor. Un 33% no practica biopsia antes de administrar inmunodepresores, sólo cuando aparecen alteraciones en la función renal durante el tratamiento. El 50% de los encuestados considera la edad inferior al año de vida como una indicación de biopsia en el síndrome nefrótico y un 24,4% cree que la edad por sí misma nunca constituye una indicación.

Conclusiones

Las encuestas son poco utilizadas en nuestro país como medio de información. La participación en ellas de expertos en el tema creemos que da validez a los resultados obtenidos. Existe diversidad de opinión entre los nefrólogos pediátricos españoles en lo que concierne a la biopsia en pacientes con síndrome nefrótico con recaídas frecuentes y corticodependiente.

Background

The role of the renal biopsy in children with nephrotic syndrome is controversial, especially in patients with frequent relapses or corticosteroid-dependent nephrotic syndrome.

Methods

We have sent a survey about the nephrotic syndrome to all the Spanish pediatric nephrologists who are members of the Spanish Association of Pediatric Nephrology. The survey is based in 7 questions about biopsy utility in the different circumstances of the illness.

Results

The survey reveals a scarce participation, 50%. The 85% of the inquired people uses the same diagnostical criterion. Refering the indication of renal biopsy in this disease, the 85% considers that it would be necessary to do it in case of corticosteroid resistance. The 57.7% of pediatric nephrologists would recommend a biopsy in children with frequently relapsing or corticosteroid-dependent nephrotic syndrome prior to cytotoxic therapy. The 33% doesn't practice biopsy before cytostatic administration, only when alterations in the renal function appear during the treatment. The 50% of the inquired considers that less than a year of age is an indication of biopsy in the nephrotic syndrome, and the 24.4% thinks that the age should never be an indication.

Conclusions

The surveys aren't much used in our country as a resource of information. We think that the participation of expert people in the surveys gives validity to the obtained results. There are different opinions among pediatric nephrologists concerning the biopsy in children with frequently relapsing and corticosteroid-dependent nephrotic syndrome.

Key words:
Nephrotic syndrome
Renal biopsy
Frequently relapsing
