In a somewhat unlikely circumstance, Dutra became the IWBF's world Jr. Welterweight champion in her very first fight, held on October 20, 1995, in Denmark.
On September 19, 1997, Dutra suffered her first professional boxing defeat, when she lost to Sarah Schmedling in the first of their two encounters, by a decision in four rounds, at Tacoma, Washington.
Finally, on November 12, she was able to avenge her earlier defeat to Schmedling, beating her by a four round unanimous decision in the women's boxing hotbed of Worley, Idaho.
Another unusual situation developed when she was given a chance to recover her old world Jr. Welterweight title by the WIBF, despite the fact she had lost her last two bouts in a row.
On October 14, 2000, she boxed Agnieszka Rylik in Warsaw, Poland for the WIBF's vacant world Jr. Welterweight title, losing by a knockout in round four.
