Abstract

Introduction: Prevention strategies are key to combating the epidemic of infections such as HIV and syphilis. The epidemiological scenario of Porto Alegre/RS for these infections shows the need for greater efforts in the area of prevention, seeking to characterize both the population that uses these strategies and the services involved in the care of exposed people. Objective: This study aimed to characterize the clinical and epidemiological profile of patients who received post-exposure prophylaxis (PEP) to HIV treated in a public hospital in Porto Alegre/RS. Methods: This is a retrospective, research, descriptive study based on the Clinical Protocol and Therapeutic Guidelines for PEP, updated in 2018 by the Ministry of Health. Prophylaxis request forms and medical records of patients treated were analyzed. Results: The population consisted of 87 women who received PEP from January to September 2019. There was a predominance of women aged between 20 and 29 years old (55.2%). The most frequent sexual exposure was consensual (69.0%) followed by sexual assault (31.0%). Porto Alegre was the place of residence of most patients (73.6%). The most frequently used therapeutic regimen was the combination of atazanavir, ritonavir, and tenofovir plus lamivudine. On the first visit, 8.0% of the patients showed reactive results for the treponemal syphilis test. Only 23.0% and 14.9% of patients returned for anti-HIV tests in the first and third months after exposure, respectively, and the results were non-reactive. Only 19 patients (21.8%) attended the consultations between 0 and 28 days after PEP. Conclusion: It was identified that a considerable percentage of women already had reactive serology for syphilis, most women did not return for follow-up within 28 and 90 days after the first consultation, more than half of the women were aged between 20 and 29 years old, and the most frequent sexual exposure was consensual. In this sense, efforts are needed, such as adequate counseling, adoption of interventions such as sending messages by cell phone, telephone calls, and preparation of educational materials, seeking to improve adherence to treatment and follow-up in the service, which is important given the scenario of epidemiology in Porto Alegre.
