ESTUDO DA RESPOSTA TERAPÊUTICA DO ÁCIDO TRICLOROACÉTICO A 90% (ATA 90%) EM PACIENTES INFECTADOS PELO PAPILOMAVIRUS HUMANO (HPV).

Abstract

Human papillomavirus (HPV) is one of the infections through sexual intercourse more often disseminated throughout the world. In Brazil it is estimated that there are around 3 to 6 million cases of HPV. There are few studies about HPV in men. This study examined the therapeutic response of patients men infected with HPV and treated topic with a solution of 90% trichloroacetic acid (ATA 90%). Were treated between January 2007 and December 2008, at the Hospital for Tropical Diseases in Araguaina (TO) 1056 patients undergoing clinical analysis by means of physical examination and penioscopia. The records of these patients were analyzed and found that 589 (55.8%) were diagnosed with HPV. Of these, 529 were selected for study as these met the following inclusion criteria: patients with macroscopic and penioscópico of HPV, which did not undergo any treatment before consultation, which were treated only with ATA 90% before and monitored for any recurrence, at least twelve months. After collecting data it was found that only 68 (12,8%) patients treated with ATA 90% had recurrence of lesions. The age of initial and final of HPV ranged from 18 to 73 years. The average age of patients with recurrence was 34.9 years, coinciding with the peak of sexual activity and the presence of multiple parters. About 80% of cases of recurrence occurred in the first six months. The association with other sexual diseases was recorded and the most prevalent pathologies: balanoposthistis (31,3%), genital herpes (9,2%), gonococal urethritis (2,8%) and no-gonococcal urethritis (0,9%). We found that the presence of other STDs contributes to treatment failure, whereas 75% of cases had tumor recurrence ATA 90% occurred in patients with an STD associated with HPV. Regarding the location of the lesions, it was found that 61.1% occurred at the distal end of the male phallus. The number of lesions detected per patient ranged from 1 to 9, with the majority (82.3%) patients had 2-5 lesions. In this study, we identified that the prevalence of HPV infection in men, STD clinic with urological monitoring was high. The therapeutic efficacy of ATA 90% was higher than the values commonly found in the literature and the recurrence rate of patients was low. We suggest that monitoring of patients with HPV after treatment with ATA is 90% done with routine queries for up to twenty-four months and quarterly consultations with the cases of recurrence. We emphasize the need for a focus on serving the man aiming to prevent controllable diseases evolve into malignancies.
