RESUMO

BACKGROUND: The causal relationship between high-risk (hr) HPV infection and precancerous lesions or cervical cancer has led to the development of strategies to increase screening performance and prevent this cancer. The increased sensitivity of DNA-HPV testing compared to cervical cytology favors DNA-HPV testing as a primary screening test. Cervical cancer screening in Brazil is opportunistic, and this cancer remains a considerable health problem with a high proportion of diagnoses in advanced stages. This paper aims to describe the design and implementation of the Cervical Cancer Screening Program with primary DNA-HPV testing (CCSP-HPV) planned for Indaiatuba City (SP), Brazil; the strategies to achieve higher population coverage; and a study protocol for cost-effectiveness analyses. METHODS: The CCSP-HPV was designed based on successful guidelines that replaced cervical cytology-based screening by the DNA-HPV test performed at 5-year intervals. The screening will be performed for the female population aged 25-64 years cared for by the public health system and aim to reach 80% coverage after completing the first round. The chosen DNA-HPV test detects 14 hr-HPV types and genotypes HPV-16 and 18. All women with a negative test will be reassessed after five years. Women showing a positive test for HPV-16 and/or 18 will be referred for colposcopy. Those showing the other 12 hr-HPV types will be tested by cytology, and if any abnormality is detected, they will also be referred for colposcopy. The histopathologic evaluation will be reviewed by a pathologist panel and aided by p16 immunohistochemistry. A cost-effectiveness analysis will be performed by a Markov model comparing the cost of the new program and the screening performed by conventional cytology five years prior (2011-2016). DISCUSSION: The new screening program is considered a breakthrough for public health regarding cervical cancer, which is the third leading cause of cancer death among Brazilian women. Achieving at least 80% coverage will have the possibility to change this scenario. The proposed program will provide a modern cervical cancer screening method for women, and information about cost-effectiveness will help other similar places support the decision of implementing cervical cancer screening using the DNA-HPV test.

RESUMO

Cervical cancer screening in Brazil is opportunistic, based on cytology and offered for women aged 25-64 years, with low coverage (30%) and 70% of cancer diagnoses done in advanced stages, without impact on mortality. The current study reports 5-year first-round results of a population-based DNA-HPV testing screening program in a Brazilian city, which intended to be a model for transition to a more efficient program. Program flowchart is simple and current, indicating repetition of a negative test after five years. The first-round (October 2017-September 2022) screened 20,551 women by DNA-HPV testing with 58.7% coverage and 99.4% compliance with the program's targeted age range. Coverage increases to 77.8% when excluding the 'pandemic period'. The DNA-HPV testing was 87.2% negative with 6.2% colposcopy referrals and 84.8% colposcopies performed. A total of 258 high-grade precursor lesions and 29 cervical cancers (mean age = 41.4 years, 83% Stage I) were detected. As a reference, 41,387 cytology tests from the previous program (2012-2016) detected 36 cervical cancers (mean age = 52.0 years, p = 0.0005), with 67% in advanced stages (p < 0.0001). Organizing cervical cancer screening using DNA-HPV testing demonstrated good coverage, high age and colposcopy compliance, and detection of more precancerous lesions and cervical cancers 10 years in advance.

RESUMO

OBJECTIVE: To evaluate the rates of precancerous lesions, colposcopy referral, and positive predictive value (PPV) by age groups of a population-based screening with DNA-HPV testing. METHODS: The present demonstration study compared 16,384 HPV tests performed in the first 30 months of the program with 19,992 women tested in the cytology screening. The colposcopy referral rate and PPV for CIN2+ and CIN3+ by age group and screening program were compared. The statistical analysis used the chi-squared test and odds ratio (OR) with 95% confidence interval (95%CI). RESULTS: The HPV tests were 3.26% positive for HPV16-HPV18 and 9.92% positive for 12 other HPVs with a 3.7 times higher colposcopy referral rate than the cytology program, which had 1.68% abnormalities. Human Papillomavirus testing detected 103 CIN2, 89 CIN3, and one AIS, compared with 24 CIN2 and 54 CIN3 detected by cytology (p < 0.0001). The age group between 25 and 29 years old screened by HPV testing had 2.4 to 3.0 times more positivity, 13.0% colposcopy referral, twice more than women aged 30 to 39 years old (7.7%; p < 0.0001), and detected 20 CIN3 and 3 early-stage cancer versus 9 CIN3 and no cancer by cytology screening (CIN3 OR= 2.10; 95%CI: 0.91-5.25; p = 0.043). The PPV of colposcopy for CIN2+ ranged from 29.5 to 41.0% in the HPV testing program. CONCLUSION: There was a significant increase in detections of cervix precancerous lesions in a short period of screening with HPV testing. In women < 30 years old, the HPV testing exhibited more positivity, high colposcopy referral rate, similar colposcopy PPV to older women, and more detection of HSIL and early-stage cervical cancer.


OBJETIVO: Avaliar as taxas de lesões pré-cancerosas, encaminhamento para colposcopia e valor preditivo positivo (VPP) por faixas etárias de rastreamento populacional com teste DNA-HPV. MéTODOS: O presente estudo de demonstração comparou 16.384 testes de HPV realizados nos primeiros 30 meses do programa com 19.992 mulheres testadas no rastreio citológico. Os programas foram comparados por taxa de encaminhamento de colposcopia e VPP para NIC2+ e NIC3+ por faixa etária. A análise estatística utilizou o teste de qui-quadrado e odds ratio (OR, na sigla em inglês) com intervalo de confiança (IC) de 95%. RESULTADOS: Os testes de HPV foram 3,26% positivos para HPV16-HPV18 e 9,92% positivos para 12 outros HPVs, com uma taxa de encaminhamento de colposcopia 3,7 vezes maior do que o programa de citologia, que teve 1,68% de anormalidades. O teste de HPV detectou 103 NIC2, 89 NIC3 e um AIS, em comparação com 24 NIC2 e 54 NIC3 detectados por citologia (p < 0,0001). O rastreio por teste de HPV no grupo etário 25 a 29 anos teve 2,4 a 3,0 vezes mais positividade, 13,0% de encaminhamento para colposcopia, 2 vezes mais que mulheres de 30 a 39 anos (7,7%; p < 0,0001), e detectou 20 NIC3 e 3 cânceres em estágio inicial versus nove NIC3 e nenhum câncer pelo rastreio citológico (NIC3 OR= 2,10; 96%CI: 0,91­5,25; p = 0,043). O VPP da colposcopia para NIC2+ variou de 29,5 a 41,0% no programa de teste de HPV. CONCLUSãO: Houve um aumento significativo na detecção de lesões pré-cancerosas do colo do útero em um curto período de rastreamento com teste de HPV. Em mulheres < 30 anos, o teste de HPV exibiu mais positividade, alta taxa de encaminhamento para colposcopia com VPP semelhante a mulheres mais velhas, e mais detecção de HSIL e de câncer cervical em estágio inicial.

RESUMO

OBJECTIVE: To compare death rates by COVID-19 between pregnant or postpartum and nonpregnant women during the first and second waves of the Brazilian pandemic. METHODS: In the present population-based evaluation data from the Sistema de Informação da Vigilância Epidemiológica da Gripe (SIVEP-Gripe, in the Portuguese acronym), we included women with c (ARDS) by COVID-19: 47,768 in 2020 (4,853 obstetric versus 42,915 nonobstetric) and 66,689 in 2021 (5,208 obstetric versus 61,481 nonobstetric) and estimated the frequency of in-hospital death. RESULTS: We identified 377 maternal deaths in 2020 (first wave) and 804 in 2021 (second wave). The death rate increased 2.0-fold for the obstetric (7.7 to 15.4%) and 1.6-fold for the nonobstetric groups (13.9 to 22.9%) from 2020 to 2021 (odds ratio [OR]: 0.52; 95% confidence interval [CI]: 0.47-0.58 in 2020 and OR: 0.61; 95%CI: 0.56-0.66 in 2021; p < 0.05). In women with comorbidities, the death rate increased 1.7-fold (13.3 to 23.3%) and 1.4-fold (22.8 to 31.4%) in the obstetric and nonobstetric groups, respectively (OR: 0.52; 95%CI: 0.44-0.61 in 2020 to OR: 0.66; 95%CI: 0.59-0.73 in 2021; p < 0.05). In women without comorbidities, the mortality rate was higher for nonobstetric (2.4 times; 6.6 to 15.7%) than for obstetric women (1.8 times; 5.5 to 10.1%; OR: 0.81; 95%CI: 0.69-0.95 in 2020 and OR: 0.60; 95%CI: 0.58-0.68 in 2021; p < 0.05). CONCLUSION: There was an increase in maternal deaths from COVID-19 in 2021 compared with 2020, especially in patients with comorbidities. Death rates were even higher in nonpregnant women, with or without comorbidities.


OBJETIVO: Comparar as taxas de mortalidade por COVID-19 entre gestantes ou puérperas e não gestantes durante a primeira e segunda ondas da pandemia brasileira. MéTODOS: Na presente avaliação dos dados do Sistema de Informação da Vigilância Epidemiológica da Gripe (SIVEP-Gripe), incluímos mulheres com síndrome respiratória aguda grave por COVID-19: 47.768 em 2020 (4.853 obstétricas versus 42.915 não obstétricas) e 66.689 em 2021 (5.208 obstétricas versus 61.481 não obstétricas) e estimamos a frequência de óbito intra-hospitalar. RESULTADOS: Identificamos 377 óbitos maternos em 2020 e 804 em 2021. A taxa de mortalidade por COVID-19 aumentou 2,0 vezes no grupo obstétrico (de 7,7 para 15,4%) e 1,6 vezes no grupo não obstétrico (de 13,9 para 22,9%) de 2020 a 2021 (odds ratio [OR]: 0,52; intervalo de confiança [IC] 95%: 0,47­0,58 em 2020 e OR: 0,61; IC95%: 0,56­0,66 em 2021; p < 0,05). Em mulheres com comorbidades, a taxa de óbitos aumentou 1,7 vezes (de 13,3 para 23,3%) e 1,4 vezes (de 22,8 para 31,4%) para os grupos obstétricos e não obstétricos, respectivamente (OR: 0,52; IC95%: 0,44­0,61 em 2020 para OR: 0,66; IC95%: 0,59­0,73 em 2021; p < 0,05). Em mulheres sem comorbidades, a taxa de mortalidade foi maior para as não obstétricas (2,4 vezes; de 6,6% para 15,7%) do que para mulheres obstétricas (1,8 vezes; de 5,5 para 10,1%; OR: 0,81; IC95%: 0,69­0,95 em 2020 e OR: 0,60; IC95%: 0,58­0,68 em 2021; p < 0,05). CONCLUSãO: Houve aumento das mortes maternas por COVID-19 em 2021 em relação a 2020, principalmente naquelas com comorbidades. As taxas de mortalidade foram ainda maiores em mulheres não grávidas, com ou sem comorbidades.

RESUMO

Background: Cervical cancer is a preventable disease, and the Brazilian screening is opportunistic and has low impact. The current study evaluated an initiative to organize screening using DNA-HPV testing as a replacement for cytology. Methods: This demonstration study examined information from 16 384 DNA-HPV tests for screening in women aged 25-64 years from Indaiatuba city between October 2017-March 2020. The comparison was 20 284 women screened using cytology between October 2014-March 2017. The flowchart indicates the repetition of a negative test in five years. HPV16- and/or HPV18-positive tests and the 12 pooled high-risk HPV-positive tests with abnormal liquid-based cytology were referred for colposcopy. If cytology was negative, the HPV test was repeated in 12 months. The analyses evaluated coverage, age-group compliance, and cancer detected. Findings: After 30 months, the coverage projection was greater than 80%. The age compliance for the HPV test was 99.25%, compared to 78.0% in the cytology program. The HPV test program showed 86.8% negative tests and 6.3% colposcopy referrals, with 78% colposcopies performed. The HPV testing program detected 21 women with cervical cancer with a mean age of 39.6 years, and 67% of cancers were early-stage compared to 12 cervical cancer cases detected by cytological screening (p=0.0284) with a mean age of 49.3 years (p=0.0158), and one case of early-stage (p=0.0014). Interpretation: Organizing cervical cancer screening using DNA-HPV testing demonstrated high coverage and age compliance in a real-life scenario, and it had an immediate impact on cervical cancer detection at an early-stage. Funding: University of Campinas, Indaiatuba City, and Roche Diagnostics.

RESUMO

OBJECTIVE: To report a modelling study using local health care costs and epidemiological inputs from a population-based program to access the cost-effectiveness of adopting hrHPV test. METHODS: A cost-effectiveness analysis based on a microsimulation dynamic Markov model. Data and costs were based on data from the local setting and literature review. The setting was Indaiatuba, Brazil, that has adopted the hrHPV test in place of cytology since 2017. After calibrating the model, one million women were simulated in hypothetical cohorts. Three strategies were tested: cytology to women aged 25 to 64 every three years; hrHPV test to women 25-64 every five years; cytology to women 25-29 years every three years and hrHPV test to women 30-64 every five years (hybrid strategy). Outcomes were Quality-adjusted life-years (QALY) and Incremental Cost-Effectiveness Ratio (ICER). RESULTS: The hrHPV testing and the hybrid strategy were the dominant strategies. Costs were lower and provided a more effective option at a negative incremental ratio of US$ 37.87 for the hybrid strategy, and negative US$ 6.16 for the HPV strategy per QALY gained. Reduction on treatment costs would influence a decrease in ICER, and an increase in the costs of the hrHPV test would increase ICER. CONCLUSIONS: Using population-based data, the switch from cytology to hrHPV testing in the cervical cancer screening program of Indaiatuba is less costly and cost-effective than the old cytology program.

RESUMO

INTRODUCTION: The influence of vaccination on composition of the human microbiome at distinct sites has been recognized as an essential component in the development of new vaccine strategies. The HPV vaccine is widely used to prevent cervical cancer; however, the influence of HPV vaccine on the vaginal microbiota has not been previously investigated. In his study, we performed an initial characterization of the microbiome and cytokine composition in the vagina following administration of the bivalent vaccine against HPV 16/18. MATERIAL AND METHODS: In this exploratory study, fifteen women between 18 and 40 years received three doses of the HPV-16/18 AS04-adjuvanted vaccine (Cervarix®). Cervicovaginal samples were collected before the first dose and 30 days after the third dose. HPV genotyping was performed by the XGEN Flow Chip technique. The cytokines IFN-γ, IL-2, IL-12p70, TNF-α, GM-CSF, IL-4, IL-5, IL-10, and IL-13 were quantitated by multiplex immunoassay. The vaginal microbiome was identified by analysis of the V3/V4 region of the bacterial 16S rRNA gene. RESULTS: The most abundant bacterial species in the vaginal microbiome was Lactobacillus crispatus, followed by L. iners. Bacterial diversity and dominant organisms were unchanged following vaccination. Small decreases in levels of pro and anti-inflammatory cytokines were observed following HPV vaccination, but there was no association between vaginal cytokine levels and microbiome composition. CONCLUSION: Vaginal microbiome is not altered following administration of the standard three-dose HPV-16/18 AS04-adjuvanted (Cervarix®) vaccine.

RESUMO

OBJECTIVE: To identify clinical, microscopic, and biochemical characteristics that differentiate cytolytic vaginosis (CV) from vulvovaginal candidiasis (VVC). METHODS: The present cross-sectional study analyzed the vaginal contents of 24 non-pregnant women aged 18 to 42 years who were attended at the Genital Infections Clinic at Centro de Atenção Integral à Saúde da Mulher da Universidade Estadual de Campinas (CAISM-UNICAMP). They were diagnosed either with (CV = 8, VVC = 8) or without vulvovaginitis or vaginal dysbiosis (controls). The socio-demographic, clinical, and gynecological data were obtained from a detailed patient interview. Samples of the vaginal contents were collected for analysis of vaginal pH, gram stain, and specific fungal culture. The Kruskal-Wallis and Fisher exact tests were used to compare the differences between the groups. Odds ratios were used to compare the categorical variables. The significance level was considered at p < 0.05. RESULTS: Both women with CV and VVC had a lumpy vaginal discharge (p = 0,002) and vaginal hyperemia (p = 0.001), compared with controls. The inflammatory process was more intense in the VVC group (p = 0.001). In the CV group, there was statistical significance for the lactobacillus amount (p = 0.006), vaginal epithelium lysis (p = 0.001), and vaginal pH (p = 0.0002). CONCLUSION: Cytolytic vaginosis and VVC diagnoses rarely differ on clinical characteristics but have different laboratorial findings. The present study highlights the importance of conducting an accurate investigation through laboratory tests rather than clinical criteria to avoid misdiagnosis.


OBJETIVO: Identificar características clínicas, microscópicas e bioquímicas que diferenciam a vaginose citolítica (VC) da candidíase vulvovaginal (CVV). MéTODOS: O presente estudo de corte transversal analisou o conteúdo vaginal de 24 mulheres não grávidas, com idades entre 18 e 42 anos, atendidas no ambulatório de Infecções Genitais do Centro de Atenção Integral à Saúde da Mulher da Universidade Estadual de Campinas (CAISM-UNICAMP). Elas foram diagnosticadas com (CV = 8, CVV = 8) ou sem vulvovaginite ou disbiose vaginal (controles = 8). Os dados sociodemográficos, clínicos e ginecológicos foram obtidos em uma entrevista detalhada do paciente. Amostras do conteúdo vaginal foram coletadas para análise do pH vaginal, coloração de Gram e cultura específica de fungos. Os testes exatos de Kruskal-Wallis e Fisher foram utilizados para comparar as diferenças entre os grupos. A razão de chances foi utilizada para comparar as variáveis categóricas. O nível de significância considerado foi de p < 0,05. RESULTADOS: As mulheres com VC e CVV apresentaram corrimento vaginal irregular (p = 0,002) e hiperemia vaginal (p = 0,001), em comparação aos controles. O processo inflamatório foi mais intenso no grupo CVV (p = 0,001). No grupo VC, houve significância estatística para a quantidade de lactobacilos (p = 0,006), lise do epitélio vaginal (p = 0,001) e pH vaginal (p = 0,0002). CONCLUSãO: Os diagnósticos de VC e CVV raramente diferem nas características clínicas, mas apresentam achados laboratoriais diferentes. O presente estudo destaca a importância de conduzir uma investigação precisa por meio de testes laboratoriais, em vez de critérios apenas clínicos, a fim de evitar erros de diagnóstico.

RESUMO

BACKGROUND: Human papillomavirus (HPV) infection is the central factor for cervical cancer, whereas epithelial immune mechanisms contribute to the progression of HPV infection and its associated lesions. The authors evaluated the expression of indoleamine 2,3-dioxygenase (IDO) and tryptophan 2,3-dioxygenase (TDO) in cervicovaginal samples from women with normal cervical epithelium or with different degrees of squamous intraepithelial lesions (SILs) and cervical cancer. METHODS: IDO expression was analyzed by immunocytochemistry in liquid-based cytology samples from 165 women, of whom 42 had cervical changes subclassified as low-grade SIL (n = 6), high-grade SIL (n = 30), or squamous cell carcinoma (SCC) (n = 6), and 123 had negative Papanicolaou smears. IDO and TDO expression also were analyzed by immunohistochemistry, and HPV and other genital pathogens were evaluated by polymerase chain reaction analysis. RESULTS: Low IDO expression was observed in normal cervical epithelium irrespective of HPV status. Increased numbers of IDO-positive squamous cells and IDO-positive leukocytes were observed in women with SIL or SCC. TDO expression was detected in leukocytes infiltrating the stroma around intraepithelial or invasive cervical lesions. Higher IDO levels were detected in organotypic epithelial cultures established from keratinocytes transduced with the HPV16 E6/E7 oncoproteins. CONCLUSIONS: The upregulation of IDO expression in leukocytes and squamous cells in HPV-associated SIL and SCC suggests that immunosuppressive mechanisms involving tryptophan metabolism may have a role in cervical carcinogenesis. Although previous studies have suggested the role of IDO in HPV pathogenesis, this is the first evidence of TDO involvement in the process. Furthermore, the current data emphasize the role of leukocytes, especially neutrophil-like cells, as an IDO source.

RESUMO

OBJECTIVE: To evaluate endocervical and vaginal environment changes in women using a levonorgestrel-releasing intrauterine system (LNG-IUS). METHODS: A quasi-experimental study included sixty women who had an LNG-IUS inserted in the Family Planning Clinic of UNICAMP between April and November of 2016. Women in reproductive age, non-pregnant, without the use of antibiotics and contraceptives seeking for LNG-IUS insertion were selected for this study. All women were evaluated with regard to vaginal and endocervical pH, vaginal and endocervical Gram-stained bacterioscopy, and Pap-smear before and two months after LNG-IUS insertion. Clinical aspects such as cervical mucus, vaginal discharge, and cervical ectopy were also observed. RESULTS: After LNG-IUS insertion, there was an increase in the following parameters: endocervical pH>4.5 (p=0.02), endocervical neutrophil amount (p<0.0001), vaginal cytolysis (p=0.04). There was a decrease in vaginal discharge (p=0.01). No statistically significant changes were found in vaginal pH, neutrophils amount in the vaginal mucosa, vaginal discharge appearance, vaginal candidiasis, bacterial vaginosis, vaginal coccobacillary microbiota, cervical mucus appearance, or cervical ectopy size. CONCLUSIONS: Short-term LNG-IUS use did not increase vulvovaginal candidiasis or bacterial vaginosis, and led to diminished vaginal discharge. Notwithstanding, this device promoted reactional changes in the vaginal and endocervical environment, without modification on cervical ectopy size.

RESUMO

Abstract Objective To evaluate the rates of precancerous lesions, colposcopy referral, and positive predictive value (PPV) by age groups of a population-based screening with DNA-HPV testing. Methods The present demonstration study compared 16,384 HPV tests performed in the first 30 months of the program with 19,992 women tested in the cytology screening. The colposcopy referral rate and PPV for CIN2+ and CIN3+ by age group and screening program were compared. The statistical analysis used the chi-squared test and odds ratio (OR) with 95% confidence interval (95%CI). Results The HPV tests were 3.26% positive for HPV16-HPV18 and 9.92% positive for 12 other HPVs with a 3.7 times higher colposcopy referral rate than the cytology program, which had 1.68% abnormalities. Human Papillomavirus testing detected 103 CIN2, 89 CIN3, and one AIS, compared with 24 CIN2 and 54 CIN3 detected by cytology (p < 0.0001). The age group between 25 and 29 years old screened by HPV testing had 2.4 to 3.0 times more positivity, 13.0% colposcopy referral, twice more than women aged 30 to 39 years old (7.7%; p < 0.0001), and detected 20 CIN3 and 3 early-stage cancer versus 9 CIN3 and no cancer by cytology screening (CIN3 OR= 2.10; 95%CI: 0.91 -5.25; p = 0.043). The PPV of colposcopy for CIN2+ ranged from 29.5 to 41.0% in the HPV testing program. Conclusion There was a significant increase in detections of cervix precancerous lesions in a short period of screening with HPV testing. In women < 30 years old, the HPV testing exhibited more positivity, high colposcopy referral rate, similar colposcopy PPV to older women, and more detection of HSIL and early-stage cervical cancer.


Resumo Objetivo Avaliar as taxas de lesões pré-cancerosas, encaminhamento para colposco pia e valor preditivo positivo (VPP) por faixas etárias de rastreamento populacional com teste DNA-HPV. Métodos O presente estudo de demonstração comparou 16.384 testes de HPV realizados nos primeiros 30 meses do programa com 19.992 mulheres testadas no rastreio citológico. Os programas foram comparados por taxa de encaminhamento de colposcopia e VPP para NIC2+ e NIC3+ por faixa etária. A análise estatística utilizou o teste de qui-quadrado e odds ratio (OR, na sigla em inglês) com intervalo de confiança (IC) de 95%. Resultados Os testes de HPV foram 3,26% positivos para HPV16-HPV18 e 9,92% positivos para 12 outros HPVs, com uma taxa de encaminhamento de colposcopia 3,7 vezes maior do que o programa de citologia, que teve 1,68% de anormalidades. O teste de HPV detectou 103 NIC2, 89 NIC3 e um AIS, em comparação com 24 NIC2 e 54 NIC3 detectados por citologia (p < 0,0001 ). O rastreio por teste de HPV no grupo etário 25 a 29 anos teve 2,4 a 3,0 vezes mais positividade, 13,0% de encaminhamento para colposcopia, 2 vezes mais que mulheres de 30 a 39 anos (7,7%; p < 0,0001 ), e detectou 20 NIC3 e 3 cânceres em estágio inicial versus nove NIC3 e nenhum câncer pelo rastreio citológico (NIC3 OR= 2,10; 96%CI: 0,91 -5,25; p = 0,043). O VPP da colposcopia para NIC2+ variou de 29,5 a 41,0% no programa de teste de HPV. Conclusão Houve um aumento significativo na detecção de lesões pré-cancerosas do colo do útero em um curto período de rastreamento com teste de HPV. Em mulheres < 30 anos, o teste de HPV exibiu mais positividade, alta taxa de encaminhamento para colposcopia com VPP semelhante a mulheres mais velhas, e mais detecção de HSIL e de câncer cervical em estágio inicial.

RESUMO

OBJECTIVE: To characterize the lipid profile in vaginal discharge of women with vulvovaginal candidiasis, cytolytic vaginosis, or no vaginal infection or dysbiosis. DESIGN: Cross-sectional study. SETTING: Genital Infections Ambulatory, Department of Tocogynecology, University of Campinas, Campinas, São Paulo-Brazil. SAMPLE: Twenty-four women were included in this study: eight with vulvovaginal candidiasis, eight with cytolytic vaginosis and eight with no vaginal infections or dysbiosis (control group). METHODS: The lipid profile in vaginal discharge of the different study groups was determined by liquid chromatography-mass spectrometry and further analyzed with MetaboAnalyst 3.0 platform. MAIN OUTCOME MEASURES: Vaginal lipids concentration and its correlation with vulvovaginal candidiasis and cytolytic vaginosis. RESULTS: PCA, PLS-DA and hierarchical clustering analyses indicated 38 potential lipid biomarkers for the different groups, correlating with oxidative stress, inflammation, apoptosis and integrity of the vaginal epithelial tissue. Among these, greater concentrations were found for Glycochenodeoxycholic acid-7-sulfate, O-adipoylcarnitine, 1-eicosyl-2-heptadecanoyl-glycero-3-phosphoserine, undecanoic acid, formyl dodecanoate and lipoic acid in the vulvovaginal candidiasis group; N-(tetradecanoyl)-sphinganine, DL-PPMP, 1-oleoyl-cyclic phosphatidic, palmitic acid and 5-aminopentanoic acid in the cytolytic vaginosis group; and 1-nonadecanoyl-glycero-3-phosphate, eicosadienoic acid, 1-stearoyl-cyclic-phosphatidic acid, 1-(9Z,12Z-heptadecadienoyl)-glycero-3-phosphate, formyl 9Z-tetradecenoate and 7Z,10Z-hexadecadienoic acid in the control group. CONCLUSIONS: Lipids related to oxidative stress and apoptosis were found in higher concentrations in women with vulvovaginal candidiasis and cytolytic vaginosis, while lipids related to epithelial tissue integrity were more pronounced in the control group. Furthermore, in women with cytolytic vaginosis, we observed higher concentrations of lipids related to bacterial overgrowth.

RESUMO

Abstract Objective To compare death rates by COVID-19 between pregnant or postpartum and nonpregnant women during the first and second waves of the Brazilian pandemic. Methods In the present population-based evaluation data from the Sistema de Informação da Vigilância Epidemiológica da Gripe (SIVEP-Gripe, in the Portuguese acronym), we included women with c (ARDS) by COVID-19: 47,768 in 2020 (4,853 obstetric versus 42,915 nonobstetric) and 66,689 in 2021 (5,208 obstetric versus 61,481 nonobstetric) and estimated the frequency of in-hospital death. Results We identified 377 maternal deaths in 2020 (first wave) and 804 in 2021 (second wave). The death rate increased 2.0-fold for the obstetric (7.7 to 15.4%) and 1.6-fold for the nonobstetric groups (13.9 to 22.9%) from 2020 to 2021 (odds ratio [OR]: 0.52; 95% confidence interval [CI]: 0.47-0.58 in 2020 and OR: 0.61; 95%CI: 0.56- 0.66 in 2021; p < 0.05). In women with comorbidities, the death rate increased 1.7-fold (13.3 to 23.3%) and 1.4-fold (22.8 to 31.4%) in the obstetric and nonobstetric groups, respectively (OR: 0.52; 95%CI: 0.44-0.61 in 2020 to OR: 0.66; 95%CI: 0.59-0.73 in 2021; p <0.05). In women without comorbidities, the mortality rate was higher for nonobstetric (2.4 times; 6.6 to 15.7%) than for obstetric women (1.8 times; 5.5 to 10.1%; OR: 0.81; 95%CI: 0.69-0.95 in 2020 and OR: 0.60; 95%CI: 0.58-0.68 in 2021; p <0.05). Conclusion There was an increase in maternal deaths from COVID-19 in 2021 compared with 2020, especially in patients with comorbidities. Death rates were even higher in nonpregnant women, with or without comorbidities.


Resumo Objetivo Comparar as taxas de mortalidade por COVID-19 entre gestantes ou puérperas e não gestantes durante a primeira e segunda ondas da pandemia brasileira. Métodos Na presente avaliação dos dados do Sistema de Informação da Vigilância Epidemiológica da Gripe (SIVEP-Gripe), incluímos mulheres com síndrome respiratória aguda grave por COVID-19: 47.768 em 2020 (4.853 obstétricas versus 42.915 não obstétricas) e 66.689 em 2021 (5.208 obstétricas versus 61.481 não obstétricas) e estimamos a frequência de óbito intra-hospitalar. Resultados Identificamos 377 óbitos maternos em 2020 e 804 em 2021. A taxa de mortalidade por COVID-19 aumentou 2,0 vezes no grupo obstétrico (de 7,7 para 15,4%) e 1,6 vezes no grupo não obstétrico (de 13,9 para 22,9%) de 2020 a 2021 (odds ratio [OR]: 0,52; intervalo de confiança [IC] 95%: 0,47-0,58 em 2020 e OR: 0,61; IC95%: 0,56-0,66 em 2021; p <0,05). Em mulheres com comorbidades, a taxa de óbitos aumentou 1,7 vezes (de 13,3 para 23,3%) e 1,4 vezes (de 22,8 para 31,4%) para os grupos obstétricos e não obstétricos, respectivamente (OR: 0,52; IC95%: 0,44-0,61 em 2020 para OR: 0,66; IC95%: 0,59-0,73 em 2021; p <0,05). Em mulheres sem comorbidades, a taxa de mortalidade foi maior para as não obstétricas (2,4 vezes; de 6,6% para 15,7%) do que para mulheres obstétricas (1,8 vezes; de 5,5 para 10,1%; OR: 0,81; IC95%: 0,69-0,95 em 2020 e OR: 0,60; IC95%: 0,58-0,68 em 2021; p < 0,05). Conclusão Houve aumento das mortes maternas por COVID-19 em 2021 em relação a 2020, principalmente naquelas com comorbidades. As taxas de mortalidade foram ainda maiores em mulheres não grávidas, com ou sem comorbidades.

RESUMO

Objective Expectant follow-up for biopsy-proven cervical intraepithelial neoplasia (CIN) 1 is the current recommendation for the management of this lesion. Nevertheless, the performance of the biopsy guided by colposcopy might not be optimal. Therefore, this study aimed to calculate the rate of underdiagnoses of more severe lesions in women with CIN 1 diagnosis and to evaluate whether age, lesion extent and biopsy site are factors associated with diagnostic failure. Methods Eighty women with a diagnosis of CIN 1 obtained by colposcopy-guided biopsy were selected for this study. These women were herein submitted to large loop excision of the transformation zone (LLETZ). The prevalence of lesions more severe than CIN 1 was calculated, and the histological diagnoses of the LLETZ specimens were grouped into two categories: "CIN 1 or less" and "CIN 2 or worse." Results The prevalence of lesions diagnosed as CIN 2 or worse in the LLETZ specimens was of 19% (15/80). Three women revealed CIN 3, and 1 woman revealed a sclerosing adenocarcinoma stage I-a, a rare type of malignant neoplasia of low proliferation, which was not detected by either colposcopy or previous biopsy. The underdiagnosis of CIN 2 was not associated with the women's age, lesion extension and biopsy site. Conclusions The standard methods used for the diagnosis of CIN 1 may underestimate the severity of the true lesion and, therefore, women undergoing expectant management must have an adequate follow-up.

RESUMO

Abstract Objective To identify clinical, microscopic, and biochemical characteristics that differentiate cytolytic vaginosis (CV) from vulvovaginal candidiasis (VVC). Methods The present cross-sectional study analyzed the vaginal contents of 24 non-pregnant women aged 18 to 42 years who were attended at the Genital Infections Clinic at Centro de Atenção Integral à Saúde da Mulher da Universidade Estadual de Campinas (CAISM-UNICAMP). They were diagnosed either with (CV = 8, VVC = 8) or without vulvovaginitis or vaginal dysbiosis (controls). The socio-demographic, clinical, and gynecological data were obtained from a detailed patient interview. Samples of the vaginal contents were collected for analysis of vaginal pH, gram stain, and specific fungal culture. The Kruskal-Wallis and Fisher exact tests were used to compare the differences between the groups. Odds ratios were used to compare the categorical variables. The significance level was considered at p < 0.05. Results Both women with CV and VVC had a lumpy vaginal discharge (p = 0,002) and vaginal hyperemia (p = 0.001), compared with controls. The inflammatory process was more intense in the VVC group (p = 0.001). In the CV group, there was statistical significance for the lactobacillus amount (p = 0.006), vaginal epithelium lysis (p = 0.001), and vaginal pH (p = 0.0002). Conclusion Cytolytic vaginosis and VVC diagnoses rarely differ on clinical characteristics but have different laboratorial findings. The present study highlights the importance of conducting an accurate investigation through laboratory tests rather than clinical criteria to avoid misdiagnosis.


Resumo Objetivo Identificar características clínicas, microscópicas e bioquímicas que diferenciam a vaginose citolítica (VC) da candidíase vulvovaginal (CVV). Métodos O presente estudo de corte transversal analisou o conteúdo vaginal de 24 mulheres não grávidas, com idades entre 18 e 42 anos, atendidas no ambulatório de Infecções Genitais do Centro de Atenção Integral à Saúde da Mulher da Universidade Estadual de Campinas (CAISM-UNICAMP). Elas foram diagnosticadas com (CV = 8, CVV = 8) ou sem vulvovaginite ou disbiose vaginal (controles = 8). Os dados sociodemográficos, clínicos e ginecológicos foram obtidos em uma entrevista detalhada do paciente. Amostras do conteúdo vaginal foram coletadas para análise do pH vaginal, coloração de Gram e cultura específica de fungos. Os testes exatos de Kruskal-Wallis e Fisher foram utilizados para comparar as diferenças entre os grupos. A razão de chances foi utilizada para comparar as variáveis categóricas. O nível de significância considerado foi de p < 0,05. Resultados As mulheres com VC e CVV apresentaram corrimento vaginal irregular (p = 0,002) e hiperemia vaginal (p = 0,001), em comparação aos controles. O processo inflamatório foi mais intenso no grupo CVV (p = 0,001). No grupo VC, houve significância estatística para a quantidade de lactobacilos (p = 0,006), lise do epitélio vaginal (p = 0,001) e pH vaginal (p = 0,0002). Conclusão Os diagnósticos de VC e CVV raramente diferem nas características clínicas, mas apresentam achados laboratoriais diferentes. O presente estudo destaca a importância de conduzir uma investigação precisa por meio de testes laboratoriais, em vez de critérios apenas clínicos, a fim de evitar erros de diagnóstico.

RESUMO

PURPOSE: To analyze the prevalence of cervical cytopathological results for the screening of cervical cancer with regard to women's age and time since the last examination in Maceió and Rio de Janeiro, Brazil, among those assisted by the Brazilian Unified Health System. METHODS: Cervical cytopathological results available in the Information System of Cervical Cancer Screening for the year 2011 were analyzed, corresponding to 206,550 for Rio de Janeiro and 45,243 for Maceió. RESULTS: In Rio de Janeiro, examination at one and two year intervals predominated, while in Maceió examination at one and three year intervals had a higher predominance. Women who underwent cervical smear screening in Maceió were older than those in Rio de Janeiro. The prevalence of invasive squamous cell carcinoma was similar for the two cities, but all the other results presented a higher prevalence in Rio de Janeiro: ASCUS (PR=5.32; 95%CI 4.66-6.07); ASCH (PR=4.27; 95%CI 3.15-5.78); atypical glandular cells (PR=10.02; 95%CI 5.66-17.76); low-grade squamous intraepithelial lesions (PR=6.10; 95%CI 5.27-7.07); high-grade squamous intraepithelial lesions (PR=8.90; 95%CI 6.50-12.18) and adenocarcinoma (PR=3.00; 95%CI 1.21-7.44). The rate of unsatisfactory cervical samples was two times higher in Maceió and that of rejected samples for analysis was five times higher in Maceió when compared to Rio de Janeiro. CONCLUSIONS: The prevalence rates of altered cervical cytopathological results was significantly higher in Rio de Janeiro than in Maceió. There is no objective information that may justify this difference. One hypothesis is that there may be a difference in the diagnostic performance of the cervical cancer screening, which could be related to the quality of the Pap smear. Thus, these findings suggest that it would be necessary to perform this evaluation at national level, with emphasis on the performance of cervical cancer screening in order to improve the effectiveness of cervical cancer control.

RESUMO

SUMMARY OBJECTIVE: To evaluate endocervical and vaginal environment changes in women using a levonorgestrel-releasing intrauterine system (LNG-IUS). METHODS: A quasi-experimental study included sixty women who had an LNG-IUS inserted in the Family Planning Clinic of UNICAMP between April and November of 2016. Women in reproductive age, non-pregnant, without the use of antibiotics and contraceptives seeking for LNG-IUS insertion were selected for this study. All women were evaluated with regard to vaginal and endocervical pH, vaginal and endocervical Gram-stained bacterioscopy, and Pap-smear before and two months after LNG-IUS insertion. Clinical aspects such as cervical mucus, vaginal discharge, and cervical ectopy were also observed. RESULTS: After LNG-IUS insertion, there was an increase in the following parameters: endocervical pH>4.5 (p=0.02), endocervical neutrophil amount (p<0.0001), vaginal cytolysis (p=0.04). There was a decrease in vaginal discharge (p=0.01). No statistically significant changes were found in vaginal pH, neutrophils amount in the vaginal mucosa, vaginal discharge appearance, vaginal candidiasis, bacterial vaginosis, vaginal coccobacillary microbiota, cervical mucus appearance, or cervical ectopy size. CONCLUSIONS: Short-term LNG-IUS use did not increase vulvovaginal candidiasis or bacterial vaginosis, and led to diminished vaginal discharge. Notwithstanding, this device promoted reactional changes in the vaginal and endocervical environment, without modification on cervical ectopy size.


RESUMO OBJETIVO: Avaliar as alterações do ambiente endocervical e vaginal em mulheres usuárias de sistema intrauterino liberador de levonorgestrel (SIU-LNG). MÉTODOS: Um estudo quase-experimental incluiu 60 mulheres que inseriram o SIU-LNG na Clínica de Planejamento Familiar da UNICAMP entre abril e novembro de 2016. Mulheres em idade reprodutiva, não gestantes, sem uso de antibióticos e contraceptivos, em busca pela inserção do SIU-LNG, foram selecionadas para este estudo. Todas as mulheres foram avaliadas quanto ao pH vaginal e endocervical, bacterioscopia vaginal e endocervical por coloração de Gram, exame de Papanicolau antes e dois meses após a inserção de SIU-LNG. Aspectos clínicos como muco cervical, corrimento vaginal e ectopia cervical também foram observados. RESULTADOS: Após a inserção do SIU-LNG houve aumento nos seguintes parâmetros: pH endocervical >4,5 (p=0,02), quantidade de neutrófilos endocervicais (p<0,0001), citolise vaginal (p=0,04). Houve diminuição do conteúdo vaginal (p=0,01). Não foram encontradas alterações estatisticamente significativas no pH vaginal, na quantidade de neutrófilos na mucosa vaginal, apecto do corrimento vaginal, candidíase vaginal, vaginose bacteriana, microbiota cocobacilar vaginal, aparência de muco cervical ou tamanho da ectopia cervical. CONCLUSÃO: O uso do SIU-LNG em curto prazo não aumentou a candidíase vulvovaginal ou a vaginose bacteriana, levou à diminuição do conteúdo vaginal. No entanto, este dispositivo promoveu mudanças reacionais no ambiente vaginal e endocervical, sem modificação no tamanho da ectopia cervical.

RESUMO

Purpose. To describe the acquisition, persistence, and clearance of HPV infection in women with CIN 2 followed up for 12 months. Methods. Thirty-seven women with CIN 2 biopsy, who have proven referral to cervical smear showing low-grade squamous intraepithelial lesions or atypical squamous cells of undetermined significance and tested for HPV, were followed up for one year with cervical smear, colposcopy, and HPV test every three months. HPV DNA was detected by the polymerase chain reaction and genotyping by reverse line blot hybridization assay. Results. CIN 2 regression rate was 49% (18/37), persistence as CIN 1 or CIN 2 was 22% (8/37), and progression to CIN 3 was 29% (11/37). Multiple HPV types were observed at admission in 41% (15/37) of cases. HPV 16 was detected at admission in 58% (11/19) of the cases that persisted/progressed and in 39% (7/18) of the cases that regressed. HPV 16 was considered possibly causal in 67% (10/15) of the cases that persisted or progressed and in 10% (1/10) of the cases that regressed (P = 0.01). Conclusion. Multiple HPV infections were frequently detected among women with CIN 2 at admission and during the followup. The CIN 2 associated with HPV 16 was more likely to persist or to progress to CIN 3.

Resumo Objetivo O seguimento de mulheres com neoplasia intraepitelial cervical (NIC) 1 comprovada por biópsia é atualmente a recomendação de conduta para esta lesão. Entretanto, o desempenho da biópsia guiada por colposcopia pode falhar. Assim, este estudo teve como objetivo estimar a taxa de subdiagnóstico de lesões mais graves em mulheres comdiagnóstico de NIC 1 e avaliar se a idade, a extensão da lesão e o local da biópsia são fatores associados à falha do diagnóstico. Métodos Foram selecionadas 80 mulheres com diagnóstico de NIC 1 obtido por biópsia dirigida por colposcopia. Estasmulheres foramsubmetidas a excisão da zona de transformação por alça diatérmica (EZTAD). A prevalência de lesões mais graves do que NIC 1 foi calculada, e os diagnósticos histológicos feitos nas amostras obtidas por EZTAD foram agrupados em duas categorias: "NIC 1 ou menos grave" e "NIC 2 ou mais grave". Resultados A prevalência de lesões diagnosticadas como NIC 2 ou mais grave nas amostras de EZTAD foi de 19% (15/80). Três mulheres apresentaram NIC 3, e uma mulher revelou adenocarcinoma esclerosante estágio I-a, um tipo raro de neoplasia maligna de baixa proliferação, que não foi detectado por qualquer exame de colposcopia ou biópsia anterior. O subdiagnóstico de NIC 2 não foi associado à idade, à extensão da lesão ou ao local da biópsia. Conclusão Os métodos de referência utilizados para o diagnóstico da NIC 1 podem subestimar a gravidade da lesão verdadeira e, portanto, as mulheres submetidas a conduta expectante devem ter um seguimento adequado.

RESUMO

OBJETIVO: Analisar a prevalência dos resultados citopatológicos empregados para o rastreamento do câncer do colo do útero em relação à faixa etária da mulher e ao tempo de realização do último exame, no Rio de Janeiro e Maceió, pelo Sistema Único de Saúde. MÉTODOS: Foram analisadas as informações do Sistema de Informação do Câncer do Colo do Útero referentes aos resultados dos exames citopatológicos realizados em 2011, que totalizaram 206.550 para Rio de Janeiro e 45.243 para Maceió. RESULTADOS: No Rio de Janeiro, predominaram exames citopatológicos realizados com intervalo de um e dois anos e, em Maceió, controles com intervalo de um e três anos. As mulheres atendidas no Maceió eram mais velhas do que aquelas do Rio de Janeiro. A prevalência do resultado citopatológico carcinoma escamoso invasor foi semelhante entre os municípios, porém todos os demais resultados apresentaram prevalência superior no Rio de Janeiro: atipias de significado indeterminado em células escamosas (RP=5,32; IC95% 4,66-6,07); atipias de significado indeterminado não podendo excluir lesão de alto grau (RP=4,27; IC95% 3,15-5,78); células glandulares atípicas (RP=10,02; IC95% 5,66-17,76); lesão intraepitelial escamosa de baixo grau (RP=6,10; IC95% 5,27-7,07); lesão intraepitelial escamosa de alto grau (RP=8,90; IC95% 6,50-12,18) e adenocarcinoma (RP=3,00; IC95% 1,21-7,44). A taxa de amostras insatisfatórias para a análise foi duas vezes maior e de lâminas rejeitadas foi cinco vezes maior em Maceió, quando comparado ao Rio de Janeiro. CONCLUSÕES: As taxas de prevalência de resultados citopatológicos foram significativamente superiores no Rio de Janeiro do que em Maceió, e não há informações objetivas ...


PURPOSE: To analyze the prevalence of cervical cytopathological results for the screening of cervical cancer with regard to women's age and time since the last examination in Maceió and Rio de Janeiro, Brazil, among those assisted by the Brazilian Unified Health System. METHODS: Cervical cytopathological results available in the Information System of Cervical Cancer Screening for the year 2011 were analyzed, corresponding to 206,550 for Rio de Janeiro and 45,243 for Maceió. RESULTS: In Rio de Janeiro, examination at one and two year intervals predominated, while in Maceió examination at one and three year intervals had a higher predominance. Women who underwent cervical smear screening in Maceió were older than those in Rio de Janeiro. The prevalence of invasive squamous cell carcinoma was similar for the two cities, but all the other results presented a higher prevalence in Rio de Janeiro: ASCUS (PR=5.32; 95%CI 4.66-6.07); ASCH (PR=4.27; 95%CI 3.15-5.78); atypical glandular cells (PR=10.02; 95%CI 5.66-17.76); low-grade squamous intraepithelial lesions (PR=6.10; 95%CI 5.27-7.07); high-grade squamous intraepithelial lesions (PR=8.90; 95%CI 6.50-12.18) and adenocarcinoma (PR=3.00; 95%CI 1.21-7.44). The rate of unsatisfactory cervical samples was two times higher in Maceió and that of rejected samples for analysis was five times higher in Maceió when compared to Rio de Janeiro. CONCLUSIONS: The prevalence rates of altered cervical cytopathological results was significantly higher in Rio de Janeiro than in Maceió. There is no objective information that may justify this difference. One hypothesis is that there may be a difference in the diagnostic performance of the cervical cancer screening, which could be related to the quality of the Pap smear. Thus, these findings suggest that it would be necessary to perform this evaluation at national level, with emphasis on the performance of cervical cancer ...
