Human papillomavirus (HPV) is the etiological agent of cervical cancer, the second most prevalent neoplasia among women. Although it has been proven that systemic lupus erythematosus (SLE) patients have higher frequency of cervical dysplasia, few studies have focused on HPV prevalence among them. This study aimed to investigate HPV prevalence among SLE patients and to evaluate associated risk factors, including the use of immunosuppressors (IM). Total DNA extracted from cervical samples of 173 SLE patients and 217 women (control group) submitted to routine cervical cytopathology was used as template in polymerase chain reaction (PCR)-based assays for detection of HPV DNA. HPV genotyping was performed by type-specific PCR, PCR-RFLP and/or DNA sequencing. Statistical methods included univariate analysis and logistic regression. Despite presenting significantly fewer HPV risk factors, SLE patients were found to have a threefold increase in HPV infection, mostly genotypes 53, 58, 45, 66, 6, 84, 83, 61, as compared with controls, who presented types 6, 18 and 61 more frequently. The higher rate of HPV infection was associated with immunosuppressive therapy. This study provides evidence that SLE patients have a high prevalence of HPV infection, which is even higher with the use of IM, a condition that might necessitate a more frequent cervical cancer screening program for these women.

Systemic lupus erythematosus (SLE) is a chronic, multisystemic autoimmune disease that occurs predominantly in women of fertile age. The association of SLE and pregnancy, mainly with active disease and especially with nephritis, has poorer pregnancy outcomes, with increased frequency of preeclampsia, fetal loss, prematurity, growth restriction, and newborns small for gestational age. Therefore, SLE pregnancies are considered high risk condition, should be monitored frequently during pregnancy and delivery should occur in a controlled setting. Pregnancy induces dramatic immune and neuroendocrine changes in the maternal body in order to protect the fetus from immunologic attack and these modifications can be affected by SLE. The risk of flares depends on the level of maternal disease activity in the 6–12 months before conception and is higher in women with repeated flares before conception, in those who discontinue useful medications and in women with active glomerulonephritis at conception. It is a challenge to differentiate lupus nephritis from preeclampsia and, in this context, the angiogenic and antiangiogenic cytokines are promising. Prenatal care of pregnant patients with SLE requires close collaboration between rheumatologist and obstetrician. Planning pregnancy is essential to increase the probability of successful pregnancies.

The objectives of this study were to measure the prevalence of adherence to drug treatment and analyze associations with characteristics pertaining to the treatment, disease, health professionals and services, and socio-demographic issues in patients with systemic lupus erythematosus (SLE) in the city of Rio de Janeiro, Brazil. A sample of 246 women with SLE was analyzed. The data were collected through individual interviews and a review of patient charts. Adherence was estimated according to the Morisk criteria, and the associated factors were analyzed by hierarchical modeling. The percentage of patients classified as adherent to treatment was 31.7%. The reasons cited for non-adherence were: carelessness with drug administration times (52.43%), forgetfulness (38.21%), adverse drug reaction (13.8%), and interruption of treatment due to improvement in symptoms (7.72%). Factors associated with adherence were: behavior towards the presence of adverse drug reaction, hematological alterations, presence of mucocutaneous manifestations, legibility of the medical prescription, schooling, and family support. The study concludes that adherence to drug treatment in SLE is a complex and multifactorial phenomenon, and the results corroborate findings from studies conducted in developed countries. The hierarchical modeling proved to be a good alternative for evaluating adherence, since it allowed visualizing the various stages in the analysis.
