RESUMO

OBJECTIVE: To characterize HPV genotype distribution in HSIL and ICC- biopsies, of WLWH, in Europe, as compared to HIV-negative women. DESIGN: Cohort- and nested -case control study. METHOD: We characterized HPV genotype distribution by performing PCR on HSIL and ICC biopsies from WLWH (n = 170); 85 cases were compared to 85 HIV-negative matched controls. The proportion of patients that might be protected by HPV vaccines was estimated. RESULTS: Among WLWH (median age 36 years-old, median duration of HIV infection 70,5 months, 79% under cART): the most frequently detected HPV were HPV16 (30%), HPV35 (16%), HPV58 (14,7%), HPV31 (13,5%), and HPV52 (11,7%). HPV16 was less frequently found in WLWH, originating from Central Africa (20,5%) compared to other African regions (35,5%) (p = 0,05) or world regions (38,8%) (p = 0,007). Multiple versus single high-risk HPV infections were associated with younger age (≤35 years)(odds ratio (OR) 2,65 (95%IC: 1,3-5,2,p = 0,002), lymphocyte CD4 count < 350 cells / µL (OR 2,7 (95%IC: 2-8,5; p = 0,005), use of cART for < 18 month OR 2,2 (95%IC: 1,1-4,5),p = 0,04) or a cumulative time with undetectable HIV viral load of less than 12 months (OR 4,2 (95%IC: 2-8.5,p = 0,001). HPV 31, 33 and 35 were more frequently detected in samples from WLWH than in HIV-negative controls (p < 0,05). The 9-valent vaccine would increase HPV protection, in HIV-positive and negative women (p < 0,001). CONCLUSION: WLWH are more frequently infected with high-risk HPV other than 16 and 18 than HIV-negative ones. The use of 9-valent vaccine may prevent HSIL or ICC in up to 85% of the women. Adding HPV 35 to the HPV vaccine panel, might improve vaccine effectiveness in WLWH.

RESUMO

OBJECTIVES: The possibility to isolate fetal cells from pregnant women cervical samples has been discussed for five decades but is not currently applied in clinical practice. This study aimed at offering prenatal genetic diagnosis from fetal cells obtained through noninvasive exocervical sampling and immuno-sorted based on expression of HLA-G. METHODS: We first developed and validated robust protocols for cell detection and isolation on control cell lines expressing (JEG-3) or not (JAR) the HLA-G antigen, a specific marker for extravillous trophoblasts. We then applied these protocols to noninvasive exocervical samples collected from pregnant women between 6 and 14 weeks of gestational age. Sampling was performed through insertion and rotation of a brush at the ectocervix close to the external os of the endocervical canal. Finally, we attempted to detect and quantify trophoblasts in exocervical samples from pregnant women by ddPCR targeting the male SRY locus. RESULTS: For immunohistochemistry, a strong specific signal for HLA-G was observed in the positive control cell line and for rare cells in exocervical samples, but only in non-fixative conditions. HLA-G positive cells diluted in HLA-G negative cells were isolated by flow cytometry or magnetic cell sorting. However, no HLA-G positive cells could be recovered from exocervical samples. SRY gene was detected by ddPCR in exocervical samples from male (50%) but also female (27%) pregnancies. CONCLUSIONS: Our data suggest that trophoblasts are too rarely and inconstantly present in noninvasive exocervical samples to be reliably retrieved by standard immunoisolation techniques and therefore cannot replace the current practice for prenatal screening and diagnosis.

RESUMO

BACKGROUND: This study compares the management and outcome of high grade squamous intraepithelial lesions (HSIL) in HIV-positive and -negative women and identifies risk factors for treatment failure. METHODS: This retrospective, controlled study includes 146 HIV-positive women, matched for HSIL, age and year of diagnosis, with 146 HIV-negative women. Differences were analysed using parametric and non-parametric tests and Kaplan-Meier survival curves. A binary logistic regression was used to assess risk factors for treatment failure. RESULTS: Persistence of cervical disease was observed most frequently in HIV-positive women (42 versus 17%) (p < 0.001) and the cone biopsy margins were more often invaded in HIV-positive-women than in HIV-negative ones. (37 versus 16%; p < 0.05). HIV-positive women, with successful cervical treatment had better HIV disease control: with significantly longer periods of undetectable HIV viral loads (VL) (19 versus 5 months; p < 0.001) and higher CD4 counts (491 versus 320 cells/mm3; p < 0.001). HIV-positive women with detectable VL at the time of dysplasia had 3.5 times (95% IC: 1.5-8.3) increased risk of treatment failure. Being treated through ablative therapy was associated with a 7.4, four-fold (95% IC: 3.2-17.3) increased risk of treatment failure compared to conization CONCLUSION: HIV-positive women have a higher risk of treatment failure of HSIL than do HIV-negative women, especially when ablative therapy is used and in women with poor control of their HIV infection. The management and the follow- up of HSIL's guidelines in this high-risk population should be adapted consequently: for HIV-positive women with uncontrolled viral load, excisional treatment should be the preferred therapy, whereas for women with undetectable viral load, CD4 + lymphocytes higher than 500 cells/mm3 and with a desire of pregnancy, ablative therapy may be considered.

RESUMO

OBJECTIVES: HPV infection may differ in women who are HIV-positive since birth (perinatally infected, P-HIV) and those who acquire HIV later in life (non-perinatally infected, NP-HIV). We assessed the HPV prevalence in relation to the HIV acquisition route and HPV vaccination status. STUDY DESIGN: Case control study comparing 22 P-HIV with 22 NP-HIV patients. Cervical, anal and oral specimen were collected for HPV PCRs. The primary outcome was the prevalence of cervical, oral and anal HPV in P-HIV and NP-HIV patients. The secondary outcome was to identify risk factors for HPV infection. Comparative statistics for two independent groups, univariate and multivariable logistic regression analyses were used. RESULTS: There were no differences between perinatally and non-perinatally infected women. Cervical dysplasia was found in 12/44 (27 %) patients and high-risk HPV (hrHPV) in 30 % of cervical (of which 89 % were hrHPV other than 16 and 18), in 3 % of oral and 65 % of anal specimens. All woman were using combined antiretroviral therapy (cART) and 64 % had HIVRNA < 20 cp/ml. A CD4 count <350/mm³ was associated with cytological abnormalities (OR: 13.52, p = 0.002) and with cervical HPV (OR: 6.11; p = 0.04); anal HPV was associated with a previous cervical dysplasia and concomitant cervical HPV infection. None of thirteen vaccinated patients had a 6/11/16/18 HPV infection. CONCLUSION: In this small series of women under cART, we did not observe a difference in HPV infection in relation to the route of HIV acquisition. The high prevalence of hrHPV other than 16 and 18 support the use of a 9-valent vaccine.

RESUMO

This review discusses the development of selective progestin receptor modulators (SPRMs) for use in women's health and specifically the use of ulipristal acetate (UPA) as emergency contraception (EC) and as a treatment for symptomatic fibroids in women who want to preserve their fertility or avoid a hysterectomy. As an EC, UPA 30 mg should be recommended for women, within 102 h of unprotected intercourse. As a treatment of fibroids, UPA (5 mg daily dose) should be administered for periods of three months as a pre-surgical strategy, reducing bleeding and fibroid size and facilitating surgery. A proportion of these patients may even avoid surgery. Future developments will demonstrate whether UPA can be used for other indications such as endometriosis and breast cancer prevention or treatment.

RESUMO

BACKGROUND: Worldwide, human papillomavirus (HPV) 16 and 18 represents 70% of high-risk (HR) HPV found in cervical cancer. However HIV-positive women are more frequently infected by HRHPV other than HPV 16 or 18 (OHR). We aimed to analyse the HRHPV genotype distribution in a cohort of HIV-positive women and to estimate the potential protection offered by the different HPV vaccines. METHODS: HRHPV genotypes by PCR and cytology were assessed in cervical samples from 508 HIV-positive women prospectively followed in Brussels. RESULTS: Women characteristics were as follows: African origin (84%), median age 42 years, median CD4 T 555/µl, 89% under combined antiretroviral therapy and 73% with HIVRNA less than 20 copies/ml. HRHPV prevalence was 23% (116/508): 38% had abnormal cytology, 76% carried OHR without HPV 16 or 18 and 11% had concomitant infection by OHR and HPV 16 or 18. The most frequent HRHPV were HPV52 (19.8%), HPV18 (14.6%), HPV31/35/51/58 (12.1% each), HPV56 (9.9%) and HPV16 (9.5%). Less than 30% of women had their HRHPV genotypes included in the bivalent or quadrivalent vaccines against HRHPV 16 and 18; however, 79% had their HRHPV covered by the ninevalent vaccine against HRHPV 16/18/31/33/45/52/58. CONCLUSION: The HRHPV genotypes distribution found in these women living in Europe with a successfully treated HIV is similar to the one found in Central Africa with HRHPV other than HPV16 or 18 retrieved in 87%. In this population, the bivalent or quadrivalent vaccines could offer protection in only 30% of women; however this protection could be extended up to 80% with the ninevalent vaccine.

RESUMO

BACKGROUND: Studies analyzing the impact of combination antiretroviral therapy (cART) on cervical infection with high-risk human papillomavirus (HR-HPV) have generated conflicting results. We assessed the long-term impact of cART on persistent cervical HR-HPV infection in a very large cohort of 652 women who underwent follow-up of HIV infection for a median duration of 104 months. METHODS: Prospective cohort of HIV-infected women undergoing HIV infection follow-up who had HR-HPV screening and cytology by Papanicolaou smear performed yearly between 2002 and 2011. RESULTS: At baseline, the median age was 38 years, the race/ethnic origin was sub-Sarahan Africa for 84%, the median CD4(+) T-cell count was 426 cells/µL, 79% were receiving cART, and the HR-HPV prevalence was 43%. The median interval of having had an HIV load of <50 copies/mL was 40.6 months at the time of a HR-HPV-negative test result, compared with 17 months at the time of a HR-HPV-positive test result (P < .0001, by univariate analysis). The median interval of having had a CD4(+) T-cell count of >500 cells/µL was 18.4 months at the time of a HR-HPV-negative test result, compared with 4.45 months at the time of a HR-HPV-positive test result (P < .0001). In multivariate analysis, having had an HIV load of <50 copies/mL for >40 months (odds ratio [OR], 0.81; 95% confidence interval [CI], .76-.86; P < .0001) and having had a CD4(+) T-cell count of >500 cells/µL for >18 months (OR, 0.88; 95% CI, .82-.94; P = .0002) were associated with a significantly decreased risk of HR-HPV infection. CONCLUSION: Sustained HIV suppression for >40 months and a sustained CD4(+) T-cell count of >500 cells/µL for >18 months are independently and significantly associated with a decreased risk of persistent cervical HR-HPV infection.

RESUMO

INTRODUCTION: Cervical infection with high-risk human papillomavirus (HRHPV) induces cervical cancer and is present in 14% of women in Europe. We assessed the prevalence and incidence of cervical HRHPV in a cohort of HIV-positive women living in Belgium. METHODS: Prospective observational program of screening and follow up of HRHPV cervical infection performed by Hybrid Capture in 825 HIV-positive women between 2002 and 2011. Women without normal cervix at baseline were excluded. RESULTS: The final analysis included 652 women: median age 38 years, African origin (81%), median HIV follow-up (66 months), median CD4 count (426 cells/µL) and 79% on antiretroviral therapy (cART). At baseline, HRHPV prevalence was 43% and decreased significantly as both age and CD4 cell count increased: highest prevalence (100%) in women <30 years and <200 CD4/µL and lowest (19%) in women >40 years and >500 CD4/µL (p<0.0001, multivariate analysis). The relative risk (RR) to carry HRHPV at baseline decreases proportionally by 11% for each 5 years-age increase and by 11% for each 100 CD4 cells/µL rise (RR=0.89, 95% CI: 0.85-0.93; p<0.0001, Poisson regression for both). During follow-up, incidence rate of HRHPV was 13.4 per 100 women-years. CONCLUSION: We found a high HRHPV prevalence of 43% and an incidence rate of 13 per 100 women-years in this cohort of HIV-positive women living in Europe and on cART. Women under 40 years-age had the highest prevalence even with CD4 count >350 cells/µL. The magnitude of HRHPV epidemiology should prompt to evaluate the clinical efficacy of vaccines against HPV in HIV-infected women.

RESUMO

BACKGROUND: Our aim was to compare the ovarian response of HIV-positive and -negative patients during IVF. METHODS: Setting - HIV and IVF reference university hospital. Twenty-seven HIV-infected patients who had undergone IVF between March 2000 and March 2005 were matched with 77 HIV-negative patients for age, aetiology of infertility, whether it was primary or secondary infertility, duration of infertility, history of pelvic surgery and type of pituitary inhibition. Outcome - poor responders were defined using one of the following criteria: a cancelled cycle (for insufficient ovarian response), less than four mature follicles (> or = 16 mm), peak serum levels of E2 lower than 1000 pg/ml. RESULTS: There were no differences between the two groups of patients for the matched criteria. The proportion of African women and of women with a history of pelvic inflammatory disease was significantly higher among HIV patients than among the control group. With the exception of a lower number of transferred embryos among HIV-positive patients versus HIV-negative ones (1.3 versus 1.9; P = 0.035), there was no significant difference between the two groups of patients regarding ovarian response parameters. CONCLUSION: HIV-infected patients who are in good general condition and who are matched to a control group present a similar ovarian response to stimulation, suggesting the existence of a similar ovarian reserve.

RESUMO

OBJECTIVES: To assess whether adequate strategies are used for the management of cervical intraepithelial neoplasia (CIN) in HIV-positive patients. SETTING: Retrospective study in a HIV reference university hospital. Sixty-eight HIV-infected patients who had undergone a cervical biopsy between January 1995 and March 2002 were matched for CIN and age with HIV-negative patients. OUTCOME: Assess mean of treatment strategy. Assess mean of treatment failure by immediate follow-up PAP smear and recurrence rate by long-term follow-up smears. RESULTS: Both groups of patients received similar treatments for their cervical anomalies. HIV-positive women were two times more likely to have involved margins after conisation than HIV-negative women (P < 0.01). Globally, two thirds of HIV-negative patients had a first follow-up PAP smear that was normal, while this was the case in only one third of HIV-positive women. These proportions were also significantly different after conisation (P < 0.01). The same differences were also observed after sustained follow-up. HIV-infected women who showed a recurrence of dysplasia were more likely to have failed antiviral therapy (9/44) than those without any recurrence (7/12) (P < 0.01). CONCLUSIONS: Higher rates of recurrence were observed among HIV-infected women, indicating that CIN management is more difficult and may require adapted guidelines in HIV-positive patients. In HIV-infected patients, an association was found between the absence of recurrence and a viral response to antiviral therapy.
