[Proteinuria selectivity and prednisone response in children with nephrotic syndrome].

Background: The proteinuria selectivity index (PSI) can predict the response to prednisone in the primary nephrotic syndrome (PNS).

Objective: To determine the association of prednisone response with the PSI in patients with PNS.

Material And Methods: With analytical cross-sectional design, pediatric patients with PNS were studied with at least six months of prior follow-up, at the Nuevo Hospital Civil de Guadalajara from 2014 to 2015.

[Dermatoglyphics differences among children with nephrotic syndrome according to steroid response].

Background: Although the association between the type of idiopathic nephrotic syndrome (INS) and a peculiar pattern of fingerprints digital would suggest the presence of genetic factors related to both, this has not been previously studied. This study aimed to evaluate if there are fingerprints patterns differences between children with steroid-resistant INS (SRNS) and those with steroid-sensitive INS (SSNS).

Methods: The frequencies distribution of arches, ulnar loops, radial loops, and whorls was studied in 60 children with SRNS, and 60 children with SSNS.
