Abstract
The female reproductive tract, similar to other mucosal sites, harbors a specific microbiome commonly dominated by Lactobacillus species (spp.), which has an essential role in maintaining health and homeostasis. Increasing evidence shows that genital tract dysbiosis and/or specific bacteria and cytokines might have an active role in the development and/or progression of HPV infection and cervical intra-epithelial neoplasia (CIN) and as a result cervical cancer. Cross-sectional and longitudinal studies reported that Lactobacillus spp. depletion increases with severity of CIN and that this may negatively affect disease regression rates. It is plausible that Lactobacillus deplete microbiome composition may lead to a pro-inflammatory environment that can increase malignant cell proliferation and HPV E6 and E7 oncogene expression. Future longitudinal cohorts and mechanistic experiments on HPV transfected cells models will further permit exploration of the impact of Lactobacillus spp. on HPV infection.

Development of cervical intraepithelial lesions and cervical cancer is not influenced by SOD2 RS4880 polymorhism. Pathol Res Pract 2021; 230:153742. [PMID: 34959097 DOI: 10.1016/j.prp.2021.153742] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/27/2021] [Revised: 12/14/2021] [Accepted: 12/16/2021] [Indexed: 01/17/2023]
Abstract
Some of the more than 200 known HPV types are essential for cervical cancer development, the third type of cancer most incident in the female population. However, for the malignant transformation occur, some cofactors are needed, as the reactive oxygen species (ROS), which can be neutralized by the antioxidant system. The SOD2 enzyme, encoded by the same name gene, is found in mitochondria and is part of the first line of defense against oxidative stress damage. Genetic polymorphisms can act by altering the efficiency of the enzyme, among which the most studied is the rs4880. Thus, the purpose of the present study was to evaluate the association of this polymorphism with HPV infection and the development of low and high grade squamous intraepithelial lesions (LSIL and HSIL) and cervical cancer, in 407 women attended by the public health system in Brazil. HPV detection in cervical secretion samples was carried out by polymerase chain reaction (PCR) and blood samples were used for polymorphism genotyping through PCR followed by restriction fragment length polymorphism (RFLP). PCR and restriction products were subjected to 10% polyacrylamide gel electrophoresis. HPV negative group (control) included 158 women and the HPV positive group (case) 249 women. The infected group was divided into No Lesion (n = 90), LSIL (n = 20), HSIL (n = 67) and cervical cancer (n = 72). The data found on socio-epidemiological characteristics and habits corroborated with data found in the literature. The distribution of genotypes in the control group was 51.9% women TC, 29.8% TT and 18.3% CC. In the case group, the distribution was 55.0% women TC, 26.1% TT and 18.9% CC. This is the first study evaluating the influence of SOD2 rs4880 polymorphism on HPV infection, the development of cervical intraepithelial lesions and cervical cancer in a Brazilian population, although additional studies are needed to corroborate the results.

Abstract
OBJECTIVE The aim of this study was to review the available literature to explore evidence indicating an association between cervical ectopy and sexually transmitted diseases, which could help in the decision to treat or not to treat this condition. METHODS A review of the literature was conducted using the PubMed, EMBASE and clinicaltrials.gov databases on ectopy of the cervix using the terms "ectopy OR ectropium AND cervix" filtered only by language, without limit of date. A total of 71 studies were found in the initial selection, of which 56 were deleted by title, abstract, or full text. The remaining 15 articles were analyzed in this study. RESULTS Cervical ectopy showed a positive association with human papillomavirus, human immunodeficiency virus, bacterial vaginosis, cervical epithelial atypia, postcoital bleeding, and desquamative inflammatory vaginitis. High-quality studies reported no association between ectopy and chlamydia infection. It was also not associated with gonococcal infection and herpes simplex. CONCLUSIONS Cervical ectopy shows a probable association with increased acquisition of some sexually transmitted diseases. Additional studies are required to confirm the possible beneficial effects of treatment and to evaluate the possible complications of these treatments.

Abstract
Human papillomavirus (HPV) infection can lead to the development of productive epithelial lesions and cervical cancer. Most cervical HPV infections are solved by cell-mediated immunity within 1-2 years, and it is known that chronic inflammation predisposes to lesions progression and tumour development. In this context, we highlight the CC chemokine receptor 5 (CCR5) which is involved in leucocytes chemotaxis to sites of inflammation, controlling the immune response. The CCR5 rs333 genotyping of 164 HPV infected women and 185 non-infected women was performed using polymerase chain reaction (PCR). HPV infection was more frequent among women under 34 years old (p < 0.001), single (p = 0.001), that received 1 minimum wage or less (p = 0.002), tobacco smokers (p = 0.007), who had the first sexual intercourse before 17 years old (p = 0.038) and that had 4 or more sexual partners during lifetime (p = 0.001). No significant difference regarding genotypes and alleles distribution according to HPV infection was observed. CCR5/CCR5 genotype was observed in 94.1% of HPV non-infected women and in 89% of infected ones, CCR5/Δ32 in 5.9% of HPV infected and in 10.4% of non-infected women, and Δ32/Δ32 was observed in only one (0.6%) infected patient. CCR5 genotypes were also not associated with cervical lesions development among HPV infected women (p = 0.167). Since CCR5 may control the antitumour immune response and cervical lesions and the studied rs333 polymorphism is not very frequent, other studies are necessary, in order to establish CCR5 role on HPV infection and squamous intraepithelial lesions development.

Abstract
Background Human papillomavirus (HPV) is the most common sexually transmitted virus in women worldwide. The persistence of the virus may cause warts that are considered benign lesions and low or high grade intraepithelial lesions (LSIL/HSIL). Immunological system plays an important role in the resolution of infections. In this context, we highlight the chemokines, which are important regulators in the development of viral infections and inflammation. Among which CXCL12 stands out, due to its pro-inflammatory features, acting as chemoattractant recruiting immune cells. Several polymorphisms were identified in CXCL12 gene including rs1801157 in the 3′-untranslated region, which is characterized by a substitution of a guanine for an adenine. Methods In this study, 195 women were classified as HPV non-infected and 169 as HPV-infected. HPV-DNA was detected by polymerase chain reaction (PCR) and the polymorphism was assessed in blood cells through restriction fragment length polymorphism analysis. Results HPV infection was more incident in women who had more than 4 sexual partners during lifetime (p = 0.007), among those who presented lower number of pregnancies (p = 0.017). HPV was more prevalent among allele A carriers confirmed by logistic regression analysis adjusted for several confounding factors [ORADJ = 4.985; CI95% (2.85–8.72), p < 0.001]. An association between allele A carriers and HSIL development (p = 0.003) was also observed. Conclusions In the present study, we demonstrated that CXCL12 rs1801157 is independently associated with HPV infection and exerts influence in HSIL development, suggesting it as a promising susceptibility biomarker for HPV infection and lesions development.

Abstract
The main purpose was to assess the effect of c.29C>T and c.74G>C polymorphisms in the TGFB1 signal peptide on HPV infection and development of cervical lesions. Cervical swabs and blood samples were obtained from 349 outpatient women, along with socio-demographic and sexual behavioral data. The study population was stratified by absence or presence of HPV DNA, as tested by PCR, as well as by lesion grade. TGFB1 signal peptide polymorphisms were genotyped using PCR-restriction fragment length polymorphism. HPV DNA was detected in 172 (49.3%) patients. c.74GC and the combined c.29CC+CT/c.74GC genotype were more frequent in infected patients (35.1 and 15.7%) than in uninfected women (6.2 and 14.7%). Accordingly, these genotypes were associated with a higher risk of HPV infection, with odds ratio and 95% confidence interval of 2.81 and 1.35-5.86 (P = 0.004) for c.74GC and 3.14 and 1.42-6.94 (P = 0.004) for the combined genotype, respectively. High-grade lesions were also 2.48 times more likely to occur in c.29CC patients than in c.29TT patients, with a 95% confidence interval of 1.01-6.08 (P = 0.047). The data demonstrate that c.74G>C and c.29C>T polymorphisms are significantly associated with risk of HPV infection and high-grade squamous intraepithelial lesions, respectively. Thus, TGFB1 signal peptide polymorphisms are potential susceptibility markers.

Abstract
Human papillomavirus (HPV) infection is common in sexually active women and viral persistence may cause intraepithelial lesions and eventually progress to cervical cancer (CC). The present study aimed to investigate epidemiological factors related to HPV infection and to evaluate viral persistence and CC precursor lesions frequencies in women from a city in the countryside of South Brazil. Three hundred women were recruited from a primary public health care clinic. The patients were interviewed and underwent sampling with cervical brushes for HPV-DNA detection/typing by a PCR-based assay and cytological analysis by Pap smear test. HPV was detected in 47 (15.7%) women. HPV infection was significantly associated with young age (<30 years) and low socio-economic status. Seventeen (5.7%) women presented cytological abnormalities, three of them with precursor CC intraepithelial lesions. A subgroup of 79 women had been previously analyzed and thirteen (16.4%) were persistently infected, two with precursor CC intraepithelial lesions and high-risk HPV types infection (both of them without cervical abnormalities in the first exam). In conclusion, HPV infection was associated with young age (<30 years) and low family income; viral persistence was low (16.4%) but related to CC precursor lesions; and HPV-DNA high risk types detection would help to screen CC in the population.
