    PURPOSE:

    To conduct a comparative study between two groups of women (HIV positive and negative) analyzing: the prevalence of cervical intraepithelial neoplasia (CIN) and cervical HPV infection; viral risk and relationship with development of CIN; and sociodemographic and behavioral parameters that influence cervical HPV infection and the development of CIN.

    METHODS:

    A cross-sectional study in which 202 HIV-positive women and 164 HIV-negative women were analyzed to assess the prevalence of CIN and 171 HIV-positive women and 160 HIV-negative women were analyzed to assess the prevalence of cervical HPV infection. The following procedures were performed on the occasion of each medical visit: collection of cervical samples for cytology and polymerase chain reaction (PCR) to detect HPV DNA; colposcopy; standardized questionnaire to collect demographic and behavioral data; and biopsy of all colposcopic changes. Histopathology was the gold standard for the diagnosis of CIN.

    RESULTS:

    The prevalence of CIN was 2.4 and 15.3% (p<0.001) and the prevalence of cervical HPV infection was 37.1 and 55.5% (p=0.002), respectively, among HIV-negative and -positive women. HIV-positive women had a higher risk of HPV infection (35.7 and 23.6%) (p=0.02). HPV 16 was the most prevalent virus type, occurring in 11.3 and 10.2% of HIV-positive and negative women and was also more prevalent among women presenting CIN in both groups. Factors associated fwith the development of CIN were: HIV infection (HT=4.64; 95%CI 2.23-9.65), age (HT=0.95; 95%CI 0.93-0.98 for each year of life) and marital status(HT=0.49; 95%CI 0.30-0.80). Associated factors for HPV infection were: HIV presence (HT=2.72; 95%CI 1.77-4.17), greater number of sexual partners (HT=1.87; 95%CI 1.23-2.84), age (HT=0.97; 95%CI 0.95-0.99 for each year of life) and marital status (HT=0.65; 95%CI 0.42-1.0 for stable union/widows).

    CONCLUSION:

    The prevalence of CIN and cervical HPV infection was higher in HIV-positive women, who also presented a higher risk of HPV infections and multiple viral types. Type 16 was predominant in both groups and in women with CIN. Older women and women with stable union/widows were less likely to acquire cervical HPV infection and CIN.

    Abstract

    Objectives

    To evaluate the incidence and factors associated with cervical intraepithelial neoplasia (CIN) and cervical infection by human papillomavirus (HPV) among HIV-positive and HIV-negative women.

    Methods

    A cohort of 103 HIV positive and 113 HIV negative women were monitored between October 2008 and February 2012, for at least one year. Procedures included cervical cytology, DNA/HPV detection by polymerase chain reaction, colposcopy with biopsy if necessary, followed by an interview for exposure characteristics data. CIN was based on the histopathological results.

    Results

    The incidence of CIN was of 8.8 and 4.6 cases/100 women-years in HIVpositive and HIV-negative women, respectively. HIV-positive women presented a hazard ratio (HR) of 2.8 for CIN and developed lesions earlier (0.86 year) than HIVnegative women (2 years) (p = 0.01). The risk of developing CIN decreased with age (HR = 0.9) and marital status (HR = 0.4). HPV patients presented a higher incidence of CIN when compared HIV-positive and HIV-negative women (p = 0.01). The incidence of HPV cervical infection was 18.1 and 11.4 cases/100 women-years in HIV-positive and HIV-negative women, respectively. Those HIV-positive presented earlier HPV infection (p = 0.002). The risk of developing HPV infection decreased with age and was higher among HIV-positive women. HPV 16 was the most common type in HIV-positive women, and also the type most closely associated with CIN in HIV-negative women.

    Conclusions

    HIV-positive women had a greater incidence of HPV and CIN, and in a shorter time interval. More rigorous and timely clinical control is required for this group.

    PURPOSE: to evaluate puerperal morbidity in HIV-infected and HIV non-infected puerperal women. METHODS: longitudinal and controlled study performed from July 2001 to September 2003, in 205 pregnant women admitted for birth delivery at Odete Valadares Maternity, divided in two groups: HIV-infected women (82) and HIV non-infected women (123). Postpartum morbidity evaluation was performed from birth delivery up to 15 days postpartum. Morbidity was categorized as minor (postpartum hemorrhage, fever and endometritis) or major (blood transfusion, deep alterations of the surgical wound and indication for surgical intervention), and was evaluated both according to the presence or absence of HIV infection and the mode of delivery. Continuous variables were analyzed by the Student’s t-test, and categorical variables were analyzed by chi2 and Fisher’s exact test using Epi-Info 2000 (CDC, Atlanta). RESULTS: puerperal morbidity was observed in 18 patients from the HIV group (22%) and in 17 patients from the control group (14%) with predominance of minor morbidity, without statistical significance, except for an increased risk of endometritis in the HIV group (RR=1.05; CI 95%:1.01-1.10). No significant difference was observed concerning the mode of delivery between the two groups. There were only two major morbidities: blood transfusion and necrotizing fasciitis. CONCLUSIONS: HIV-infected and non-infected puerperal women have a similar morbidity, despite the lower morbidity in the HIV non-infected group and the increased risk of endometritis in the HIV group. Clinical puerperium follow-up is a strategic control tool for an early identification of maternal morbidity.

    PURPOSE: to evaluate the expression of E-cadherin in cervical lesions of patients suffering from HIV infection. METHODS: we conducted a study with 77 patients with cervical HPV infection, 40 of them were HIV seropositive and 37 HIV seronegative who underwent colposcopy and a biopsy of the cervix. The material obtained by biopsy of the cervix was sent for histopathologic and immunohistochemical study. Sections were obtained and mounted on silanized slides and examined by an observer who was blind to patient serology. E-cadherin antibody, clone NHC-38 diluted 1:400 (DAKO) and the Novolink polymer system (Novocastra) were used. The expression of E-cadherin was determined on the epithelial cell membrane based on the extent of the stained area. The χ2 test with Yates correction or the Fisher's Exact test was used for comparison of the proportion in univariate analysis. All the variables with p<0.25 were included in the logistic regression model, called initial model. The analyses were carried out using the SPSS software, with the level of significance set at 5%. RESULTS: the expression of E-cadherin was observed in up to the internal 1/3 of the epithelium in 59.3% of cases and in up to 2/3 of the epithelium in 11.1% of cases, but in 29.6% of cases the expression was identified throughout the thickness of the epithelium in HIV-seronegative patients. In contrast, in HIV-seropositive patients, 45.9% showed expression up to 1/3 of the epithelium, 13.5% showed expression in up to 2/3 of the epithelium, and 40.5% showed expression throughout the thickness of the epithelium. E-cadherin expression did not differ between groups (p=0.5). However, the multivariate analysis identified a significant association between high-grade cervical injury and E-cadherin expression in 2/3 and 3/3 of the epithelium (p=0.001; χ2=36.9). CONCLUSIONS: the expression of E-cadherin in the epithelial cell membrane is not associated with infection by the human immunodeficiency virus, but with the degree of intraepithelial cervical injury.

    PURPOSE: to evaluate association between CD4+ cell count and cervical intraepithelial lesion severity in HIV-infected women. METHODS: cross-sectional study of 87 HIV-infected patients which were confirmed by previous serologic examinations. All had cervical HPV diagnosed by polymerase chain reaction (PCR). All patients underwent anamnesis, physical examinations and colposcopy. Cervix biopsy was performed when indicated by colposcopical examination. Histopathological results followed Richart's classification, adapted by Wright, and CD4+ cell count and cervical intraepithelial lesion severity association was analysed by comparison of means using analysis using analysis of variance (ANOVA). RESULTS: among 60 biopsied women 24 were found (40.0%) with CIN I, eight (13.3%) with CIN II, three (5%) with CIN III, 14 (23.3%) with chronic cervicitis and 11 with cytopathic effect of HPV, without cell polarity loss. This corresponds to 35 (58.3%) women with intraepithelial lesion of low grade (CIN I + HPV) and 11 (18.3%) with intraepithelial lesion of high grade (CIN II + CIN III). There was no significant association between CD4+ cell count mean and cervical intraepithelial lesion severity (p=0.901). CONCLUSIONS: there was no association between CD4+ cell count and cervical intraepithelial lesion severity diagnosed by histopathological examination.

    PURPOSE:

    To evaluate the prevalence of toxoplasmosis, rubella, cytomegalovirus, hepatitis B&C and syphilis (Torchs) in a cohort pregnant women and to identify the sociodemographic, clinical and laboratory factors.

    METHODS:

    A total of 1,573 HIV-infected pregnant women from a Brazilian metropolitan region were studied between 1998 and 2013. The results of serological tests were available for 704 (44.8%) pregnant women. Pregnant women were considered to be Torchs positive (Gtp) when they had positive results for at least one of these infections, and to be Torchs negative (Gtn) when they had negative results for all of them. Maternal covariables were: age, marital status, educational level, time and mode of infection, CD4 lymphocyte count, viral load at delivery, and use of antiretroviral therapy (ARV). Neonatal covariables were: HIV infection, prematurity, low birth weight, neonatal complications, abortion and neonatal death. Odds ratios with 95% confidence interval were used to quantify the association between maternal and neonatal variables and the presence of Torchs.

    RESULTS:

    Among 704 pregnant women, 70 (9.9%; 95%CI 7.8-12.4) had positive serological tests for any Torchs factor. The individual prevalence rates were: 1.5% (10/685) for toxoplasmosis; 1.3% (8/618) for rubella; 1.3% (8/597) for cytomegalovirus; 0.9% (6/653) for hepatitis B and 3.7% (20/545) for hepatitis C; and 3.8% (25/664) for syphilis. The HIV Vertical HIV transmission was 4.6% among Gtp pregnant women and 1.2% among Gtn women. Antiretroviral therapy (ARV), vertical transmission, low birth weight and neonatal complications were significantly associated with Torchs positivity in univariate analysis.

    CONCLUSIONS:

    The Torchs prevalence found in the study was high for some infections. These findings emphasize the need to promote serological Torchs screening for all pregnant women, especially HIV-infected women, so that an early diagnosis can be made and treatment interventions can be implemented to prevent vertical HIV transmission.

    PURPOSE: to verify the accuracy of uterine cervix cytology for HPV diagnosis, as compared to polymerase chain reaction (PCR) in samples of women with HIV. METHODS: 158 patients who had undergone a first collection of material from the uterine cervix with Ayre's spatula for PCR were included in the study. Then, another collection with Ayre's spatula and brush for oncotic cytology was performed. Only 109 slides were reviewed, as 49 of them had already been destructed for have being filed for over two years. RESULTS: the prevalence of HPV was 11% in the cytological exam and 69.7% in the PCR. Age varied from 20 to 61 years old, median 35 years. The HIV contagious route was heterosexual in 91.8% of the cases, and 79.1% of the patients had had from one to five sexual partners along their lives. The most frequent complaint was pelvic mass (5.1%), and 75.3% of the women had looked for the service for a routine medical appointment. The categorical variable comparison was done through contingency tables, using the χ2 test with Yates's correction to compare the ratios. The Fisher's test was used when one of the expected rates was lower than five. In the comparison of diagnostic tests, sensitivity, specificity and similarity ratios have been calculated. Among the 76 patients with HPV, detected by PCR, only 12 had the diagnosis confirmed by cytology (sensitivity=15.8%), which on the other hand did not present any false-positive results (specificity=100%). Concerning the HPV presence, the cytological prediction for positive results was 100% and 33.3% for negative, when both results were compared. Among the 12 patients with HPV positive cytology, four (33.3%) presented cervical intraepithelial neoplasia (OR=56; positive similarity ratio=positive infinity; negative similarity ratio=0.83). CONCLUSIONS: As the cytology specificity is quite high, it is possible to rely on the positive result, which means that a positive result will surely indicate the presence of HPV. The low sensitivity of cytology does not qualify it as a survey exam for HPV detection in this female group.

    PURPOSE: to evaluate risk factors associated with cervical intraepithelial lesion recurrence after LEEP conization. METHODS: nested case-control study in a cohort of 201 patients with cervical intraepithelial lesion, that were submitted to LEEP conization. Average follow-up of these patients was 2 years. Ninety-four HIV-infected women and 107 non-infected were enrolled. Cervical conization was achieved by the Loop Electrosurgical Excision Procedure (LEEP). Evaluated surgical biopsy histopathological characteristics were lesion grade, lesion borders and glandular involvement. After surgery all patients were submitted to a colposcopy and cytological evaluation every six months. Recurrent lesions were defined it confirmed by biopsy after surgery. Cases were patients with and controls patients without recurrence. chi2 test and multivariable analysis by logistic regression were used for group comparisons. Kaplan Meier's method was performed for the survival analyses (log-rank test). RESULTS: 40 patients had lesion recurrence. Initially, significant variables were: partner number, HIV-infection, lesion borders and glandular involvement. The most frequent recurrence occurred when there were simultaneous association between positive margins and glandular involvement as indicator for recurrence risk. After logistic regression analysis the main factors associated with lesion recurrence were: glandular involvement (OR-9.1; 95% CI:13.0- 27.5); HIV-infection (OR-4.6; 95% IC:1.1-6.3); compromised margins (OR-2.6; 95% IC:1.9-11.2). CONCLUSIONS: risk factors associated with cervical intraepitelial lesion recurrence were HIV-infection, glandular involvement and compromised margins.
