Abstract:
Urinary tract infections are responsible for most human infections, these are caused by bacteria, fungi, protozoa and associated microorganisms. The goal of this study was to determine the rate of vaginal infection-causing agents in routine cytological exams and also to evaluate the characteristics of positive tested Pap smears. A retrospective documental with descriptive aspect research was performed in a Clinical Pathology laboratory from Maceió-AL. The results of the Pap smears exams for Trichomonas vaginalis, Gardnerella vaginalis, Candida spp and HPV were arranged in a database as well as other data such as bacterial, protozoan, fungal and viral coinfections. The sample was composed by 18.645 women who have undergone Pap smear exams from 2013 to 2017. Of these analyzed exams, 27.4% in 2013, 10.9% in 2014, 10.6% in 2015, 15.2% in 2016 and 13.67% in 2017 were within normal range, however more than half of these exams presented some infections caused by unspecific or microbiological agents. By analyzing all the reports, 4.073 (21.84%) presented inflammations caused by some species of infectious agent with the following rate order: G. vaginalis and T. vaginalis. Furthermore, it was possible to confirm high rates of coinfection by and Candida spp. The rate of genital infections in this study highlights that there is a public health matter that must be controlled, which points a greater need for monitoring, guidance and actions towards greater awareness in order to prevent these problems.
Insights
This study found that over half of Pap smear exams revealed infections, with Gardnerella vaginalis and Trichomonas vaginalis being the most common. These high rates of genital infections indicate a significant public health concern requiring increased awareness and control measures.
Area of Science:
- Gynecology
- Microbiology
- Public Health
Background:
- Urinary tract infections are common human infections caused by various microorganisms.
- Vaginal infections are a significant component of overall human infections.
- Routine cytological exams, like Pap smears, can detect these infectious agents.
Purpose of the Study:
- To determine the prevalence of vaginal infection-causing agents in routine Pap smear screenings.
- To evaluate the characteristics of Pap smears positive for infectious agents.
- To assess the public health implications of identified genital infections.
Main Methods:
- A retrospective, descriptive study was conducted in a Clinical Pathology laboratory.
- Data from 18,645 Pap smear exams performed between 2013 and 2017 were analyzed.
- Results for Trichomonas vaginalis, Gardnerella vaginalis, Candida spp., and HPV, along with coinfections, were recorded.
Main Results:
- Over half of the analyzed Pap smear exams showed infections, with rates varying annually.
- A total of 21.84% of exams (4,073) presented infections, primarily caused by Gardnerella vaginalis and Trichomonas vaginalis.
- High rates of coinfection with Candida spp. were also observed.
Conclusions:
- The study highlights a significant public health issue due to the high prevalence of genital infections.
- There is a need for enhanced monitoring, guidance, and public awareness campaigns for prevention.
- Effective control strategies are crucial to manage the burden of these infections.
