Background: Studies on diabetic foot and its complications involving a significant and representative sample of patients in South American countries are scarce. The main objective of this study was to acquire clinical and epidemiological data on a large cohort of diabetic patients from 19 centers from Brazil and focus on factors that could be associated with the risk of ulcer and amputation.
Methods: This study presents cross sectional, baseline results of the BRAZUPA Study.
Objective: To report the experience regarding patients with steroid 5alpha-reductase type 2 deficiency from three different clinical services in Brazil.
Casuistic And Methods: Twenty five patients with clinical and hormonal features of 5alpha-reductase deficiency from 23 families (15 from Bahia, 7 from São Paulo and 1 from Minas Gerais) were included in this study. Clinical, hormonal and molecular data were evaluated.
Mutations of the steroid 5alpha-reductase type 2 (SRD5A2) gene in 46,XY subjects cause masculinization defects of varying degrees, due to reduced or impaired enzymatic activity. In this study, sequence abnormalities of the SRD5A2 gene were assessed by polymerase chain reaction with specific primers and automated sequencing analysis in DNA samples from 20 patients with suspected steroid 5alpha-reductase type 2 deficiency from 18 Brazilian families. Eleven subjects presented SRD5A2 homozygous single-base mutations (two first cousins and four unrelated patients with G183S, two with R246W, one with del642T, one with G196S, and one with 217_218insC plus the A49T variant in heterozygosis), whereas four were compound heterozygotes (one with Q126R/IVS3+1G>A, one with Q126R/del418T, and two brothers with Q126R/G158R).
