Estudo da prevalência da infecção pelo Papiloma Vírus Humano (HPV) em mulheres portadoras de Lúpus Eritematoso Sistêmico (LES) em um hospital de referência de Belém

Abstract

Introduction: Worldwide, cervical cancer is the third most common type of cancer. Almost all cervical cancers are caused by HPV (human papilloma virus), however, autoimmunediseases, such as Systemic Lupus Erythematosus (SLE) are also linked toan increased risk of cervical cancer. Objective: To analyzethe prevalence of HPV infection and associated risk factors in SLE patients,who are treated at referred care center in Belém-Pará. Methods: In this study, was investigated 70 women who has lupus and underwent cervical cancer screeningusing the Pap smear. The patients were divided into two groups of patients: women infected with HPV (n = 16) and not infected (n = 54). The detection and subtyping was performedby polymerase chain reaction (PCR). It was applied the Chi-square, binomial test, Fisher test and tstudent test with level alpha = 0.05 for rejecting the null hypothesis. This procedure was performed by using BioEstat software version 5.3. Results: The prevalenceof HPV in these patients was 22.8% with significant statistical results noted in women at the ages between 18-25 (p-value <0.001). Changes in the Pap smear and musculoskeletal symptoms at the time of collection, had also significant statistical results (p-value = 0.0360*, p-value = 0.0463 * respectively).Regarding the use of immunosuppressive drugs, the results were not associated with the virus infection. The most prevalent subtypes were HPV type 58 (37.5%) and HPV type 31(31.3%), and two patients manifested an infection of more than one genotype. Conclusion: InSLE patients studied the age factor has been implicated in an increased risk of infection, most of these patients had1-5years ofdiagnosis andallpatients with HPVpositive had abnormalities on examination of the PCCU.
