RESUMEN

We assessed cumulative detection and determinants of anal high-grade squamous intraepithelial lesions (HSIL) in men who have sex with men living with HIV who underwent three visits over two years, with cytology and high-resolution anoscopy (HRA), within the ANRS-EP57-APACHES study. Cumulative HSIL detection was 33% (134/410), of which 48% were detected at baseline. HSIL detection varied considerably by center (13-51%). Strongest HSIL determinants were baseline HPV16 (adjusted odds ratio [aOR] 8.2; 95% confidence interval [95%CI] 3.6-18.9), and p16/Ki67 (aOR 4.6; 95%CI 2.3-9.1). Repeat annual cytology and HRA improved HSIL detection but did not fully compensate between-center heterogeneity.

RESUMEN

BACKGROUND: Age-specific data on anal, and corresponding cervical, human papillomavirus (HPV) infection are needed to inform female anal cancer prevention. METHODS: We centrally reanalyzed individual-level data from 26 studies reporting HPV prevalence in paired anal and cervical samples by human immunodeficiency virus (HIV) status and age. For women with HIV (WWH) with anal high-grade squamous intraepithelial lesions or worse (HSIL+), we also investigated concurrent cervical cytopathology. RESULTS: In HIV-negative women, HPV16 prevalence decreased significantly with age, both at anus (4.3% at 15-24 years to 1.0% at ≥55 years; ptrend = 0.0026) and cervix (7.4% to 1.7%; ptrend < 0.0001). In WWH, HPV16 prevalence decreased with age at cervix (18.3% to 7.2%; ptrend = 0.0035) but not anus (11.5% to 13.9%; ptrend = 0.5412). Given anal HPV16 positivity, concurrent cervical HPV16 positivity also decreased with age, both in HIV-negative women (ptrend = 0.0005) and WWH (ptrend = 0.0166). Among 48 WWH with HPV16-positive anal HSIL+, 27 (56%) were cervical high-risk HPV-positive, including 8 with cervical HPV16, and 5 were cervical HSIL+. CONCLUSIONS: Age-specific shifts in HPV16 prevalence from cervix to anus suggest that HPV infections in the anus persist longer, or occur later in life, than in the cervix, particularly in WWH. This is an important consideration when assessing the utility of cervical screening results to stratify anal cancer risk.

RESUMEN

BACKGROUND: Human papillomavirus (HPV) infection is more frequent in men having sex with men (MSM) who are living with human immunodeficiency virus (HIV) than in MSM without HIV. There are currently no data regarding HPV infections in preexposure prophylaxis (PrEP)-using MSM. METHODS: MSM living without HIV who were enrolled in the Agence Nationale de Recherches sur le SIDA et les Hépatites Virales "Intervention Préventive de l'Exposition aux Risques avec et pour les hommes Gays" PrEP study were prospectively enrolled. Anal, penile, and oral samples were collected at baseline and every 6 months for HPV detection and genotyping. Anal swabs for cytology were obtained at baseline and at 24 months. RESULTS: We enrolled 162 participants. The prevalences of any HPV genotypes at baseline were 92%, 32%, and 12% at the anal, penile, and oral sites, respectively. High-risk (HR) HPV genotypes were observed in 84%, 25%, and 10% of anal, penile, and oral baseline samples, respectively. Nonavalent HPV vaccine genotypes were observed in 77%, 22%, and 6% of anal, penile, and oral baseline samples, respectively. Multiple infections were observed in 76%, 17%, and 3% of cases at the anal, penile, and oral sites, respectively. The most frequent HR genotypes were HPV 53, 51, and 16 in anal samples; HPV 33, 39, and 73 in penile samples; and HPV 66 in oral samples. The incidence of any HPV genotype at the anal site was 86.2/1000 person-months and the incidence of HR-HPV genotypes was 72.3/1000 person-months. The baseline cytology was normal in 32% of cases and was classified as atypical squamous cells of undetermined significance, low-grade squamous intra-epithelial lesion, high-grade squamous intra-epithelial lesion (HSIL), and atypical squamous cells that cannot exclude HSIL in 23%, 40%, 5%, and 1% of cases, respectively. CONCLUSIONS: PrEP users have a similar risk of HPV infection as MSM living with HIV and the risk is much higher than that previously reported in MSM living without HIV.

RESUMEN

BACKGROUND: Prospective data on the natural history of anal human papillomavirus (HPV) infection are scarce in human immunodeficiency virus (HIV)-infected men who have sex with men (MSM). METHODS: We analyzed incidence and clearance of HPV-16 and HPV-18 in a French cohort of HIV-infected MSM, aged ≥35 years, followed-up annually (n = 438, 2014-2018). RESULTS: Human papillomavirus-16 and HPV-18 incidence were similar (~10% incident infections at 24 months). Human papillomavirus-16 incidence was higher among high-grade versus no lesion at baseline (adjusted incidence rate ratio = 3.0; 95% confidence interval, 1.07-8.18). Human papillomavirus-16 cleared significantly slower than HPV-18 (32% versus 54% by 24 months). CONCLUSIONS: In conclusion, anal HPV-16 is more persistent than HPV-18, and its incidence correlates with a prior detection of high-grade lesions.

RESUMEN

Background: We assessed prevalence and risk factors for anal human papillomavirus (HPV) in human immunodeficiency virus (HIV)-positive men who have sex with men (MSM), who are at high-risk of HPV-related anal cancer. Methods: APACHES is a multicentric, prospective study of anal HPV infection and lesions in HIV-positive MSM aged ≥35 years. At baseline, participants underwent anal swabs for HPV and cytology, plus high-resolution anoscopy. High-risk HPV (HR-HPV) was tested by Cobas4800, with genotyping of HR-HPV positives by PapilloCheck. Results: Among 490 participants, prevalence of HPV16 and HR-HPV was 29% and 70%, respectively, and did not differ significantly by age, sexual behavior, or markers of HIV or immune deficiency. Smoking was the only, albeit weak (odds ratio, 1.8; 95% confidence interval, 1.2-2.7), predictor of HR-HPV. High-risk HPV and HPV16 prevalence increased strongly with anal diagnosis severity, both by worse cytological/histological (composite) diagnosis at APACHES baseline and worse historical diagnosis. HPV16 rose from 19% among participants who were negative for lesions to 63% among participants with high-grade lesions. In contrast, non-HPV16 HR-HPVs were less prevalent in high-grade (37%) than negative (64%) composite diagnosis, and their causal attribution was further challenged by multiple HPV infections. Conclusions: Human papillomavirus 16 is ubiquitously frequent among human immunodeficiency virus -positive men having sex with men, and more strongly associated with high-grade anal lesions than other high-risk types, confirming it as a target for anal cancer prevention.

RESUMEN

PURPOSE: The purpose of the study was to estimate the number of new breast cancer cases in France in 2015 attributable to breastfeeding for durations below recommendations (at least 6 months per child), and cases prevented through historical breastfeeding. As a secondary analysis, the corresponding numbers for ovarian cancer were estimated. METHODS: Historical breastfeeding data were obtained from population surveys. Duration of breastfeeding data were obtained from the French Épifane cohort study. Relative risks were obtained from meta-analyses, cohort, and case-control studies. Cancer incidence data were obtained from the French Network of Cancer Registries. A 10-year latency period was assumed. RESULTS: Among parous women 25 years of age and older, 14.1% breastfed for at least 6 months per child born before 2006. As a result, 1,712 new breast cancer cases (3.2% of all new breast cancer cases) were attributable to breastfeeding for < 6 months per child, while actual breastfeeding practices prevented 765 breast cancer cases. Furthermore, 411 new ovarian cancer cases (8.6% of all new ovarian cancer cases) may be attributable to breastfeeding for < 6 months per child, with breastfeeding preventing 163 ovarian cancer cases. CONCLUSIONS: The historically low breastfeeding prevalence and duration in France led to numerous avoidable cancer cases.

RESUMEN

To provide an assessment of the burden of cancer in France in 2015 attributable to infectious agents. A systematic literature review in French representative cancer cases series was undertaken of the prevalence of infectious agents with the major associated cancer types. PubMed was searched for original studies published up to September 2016; random-effects meta-analyses were performed. Cancer incidence data were obtained from the French Cancer Registries Network, thereby allowing the calculation of national incidence estimates. The number of new cancer cases attributable to infectious agents was calculated using population-attributable fractions according to published methods. Of the 352,000 new cancer cases in France in 2015, 14,336 (4.1% of all new cancer cases) were attributable to infectious agents. The largest contributors were human papillomavirus (HPV) and Helicobacter pylori, responsible for 6333 and 4406 new cancer cases (1.8 and 1.3% of all new cancer cases) respectively. Infectious agents caused a non-negligible number of new cancer cases in France in 2015. Most of these cancers were preventable. The expansion of vaccination (i.e., for hepatitis B virus and HPV) and screen-and-treat programs (for HPV and hepatitis C virus, and possibly for H. pylori) could greatly reduce this cancer burden.

RESUMEN

Background: Effectiveness of human papillomavirus (HPV) vaccines in the context of both guidelines, which recommend vaccination at 14 years and modest vaccine coverage, is poorly documented. Methods: Residual specimens from females aged <25 years undergoing chlamydia testing were collected, together with demographic, sexual behavior, and vaccine status data. Human pappilomavirus genotypes were determined using the PapilloCheck test system. We compared vaccine type (VT; types 6, 11, 16, 18) prevalence according to vaccination status and identified factors associated with VT prevalence. Results: Of 3736 eligible samples, 822 were from vaccinated women according to immunization record, 1021 from women self-reporting vaccination, and 1893 from unvaccinated women. Adjusted vaccine effectiveness for confirmed vaccinated compared with unvaccinated women was 95.93% (95% confidence interval [CI] = 90.22-98.32) against VT HPV and 38.37% (95% CI = 12.68-56.51) against cross-reactive genotypes (HPV 31, 33, 45), respectively. Vaccine type HPV prevalence was significantly lower (0.61%) among confirmed-vaccinated women than among those who self-reported vaccination or unvaccinated women (1.76% and 15.0%, respectively). Factors associated with prevalent VT in multivariable analysis were vaccine status, positive Chlamydia trachomatis and ≥4 partners in the preceding year. Conclusion: Our study demonstrates evidence of high effectiveness of HPV prophylactic vaccines at an individual level, supporting that wider implementation will help to reduce cervical cancer and precursors incidence.

RESUMEN

BACKGROUND: Little is known about the type-specific prevalence of anal human papillomavirus (HPV) infection and risk factors for anal high-risk (HR) HPV infection in human immunodeficiency virus (HIV)-infected women. METHODS: A cross-sectional study of anal and cervical HPV infection was nested within a gynecological cohort of HIV-infected women. Specimens were tested for type-specific DNA using a polymerase chain reaction-based assay. RESULTS: The study population consisted of 311 women with a median age of 45.3 years, of whom 42.8% originated from sub-Saharan Africa and 96.8% were receiving combination antiretroviral therapy. The median CD4(+)cell count was 612/µL, and the HIV load was <50 copies/mL in 84.1%. HR-HPV types were detected in the anal canal in 148 women (47.6%) and in the cervix in 82 (26.4%). HPV-16 was the most prevalent type in both the anal canal (13.2% of women) and the cervix (5.1%). In multivariable analysis, factors associated with prevalent anal HR-HPV infection were CD4(+)count <350/µL (odds ratio, 2.9; 95% confidence interval, 1.3-6.5), concurrent cervical lesions (2.6; 1.0-4.3), and cervical HR-HPV infection (1.8; 1.0-3.2). CONCLUSIONS: The high prevalence of HR-HPV types, including HPV-16, in the anal canal of HIV-positive women is concerning. Anal cancer screening should be considered for HIV-positive women as part of their routine care.

RESUMEN

BACKGROUND: Although human immunodeficiency virus (HIV)-infected women are at high risk for anal cancer, few data have been published on prevalence of and risk factors for anal precancer and potential screening strategies in this risk group. METHODS: A cross-sectional anal screening study was nested in a gynecological cohort of HIV-infected women. Anal swab specimens were collected for cytology and human papillomavirus (HPV) testing. High-resolution anoscopy, with biopsy when indicated, was systematically performed. RESULTS: Among the 171 enrolled women, median age was 47.3 years and 98% were receiving combination antiretroviral therapy. Median CD4(+) count was 655 cells/µL and HIV load was <50 copies/mL in 89% of subjects. High-grade anal intraepithelial neoplasia or worse (HG-AIN+) was diagnosed in 12.9% (n = 21). In multivariable analysis, a history of cervical squamous intraepithelial lesion (odds ratio [OR], 4.2; 95% confidence interval [CI], 1.1-16.4) and anal HPV-16 infection (OR, 16.1; 95% CI, 5.4-48.3) was associated with increased risk of HG-AIN+. Abnormal anal cytology and HPV-16 infection performed best as a screening strategy for HG-AIN+ histology, with positive likelihood ratios of 3.4 (95% CI, 2.3-5.1) and 4.7 (95% CI, 2.5-8.7) and negative likelihood ratios of 0.2 (95% CI, .07-.8) and 0.4 (95% CI, .2-.9), respectively. CONCLUSIONS: HIV-infected women with a history of HPV-associated cervical disease are at increased risk for HG-AIN+ and should be offered anal cancer screening. Anal cytology and HPV-16 genotyping had the best screening performance. Anal cytology is easy to perform routinely; it may be the best candidate for screening for HG-AIN among HIV-infected women.

RESUMEN

The aim of this work was to describe the prevalence of type-specific Human papillomavirus (HPV) infection in women attending organized cervical cancer screening program in Uruguay. Nine hundred sixty-five liquid cervical cell samples obtained after collection of cervical smears for cytology were assessed for HPV DNA using the Papillocheck system (Greiner BioOne). The overall prevalence of High-Risk (HR) HPV infections was 20.8% and increased from 16.5% in women with normal cytology to 93.3% in HSIL. Prevalence of HPV 16 and/or 18 was 6.3% and HPV 16 was the most prevalent genotype in normal cytology (3.6%). The five most prevalent genotypes were HPV 16, 31, 51, 56, and 39. The overall prevalence peaked below age 30. This study provides essential baseline information at national level on type-specific HPV prevalence in Uruguay before the introduction of HPV vaccination. It documents the current prevalence of each of the oncogenic genotypes in a population attending cervical cancer screening program, suggesting that at least 64.7% of high risk lesions are potentially preventable by available HPV vaccines, and possibly augmentable if cross-protection against non-vaccine HPV types 31, 33, and 45 is confirmed.

RESUMEN

BACKGROUND: Mucosal human papillomavirus (HPV) infection is a necessary cause of cervical cancer. Vaccine and non-vaccine genotype prevalences may change after vaccine introduction. Therefore, it appears essential to rank HPV genotypes according to their oncogenic potential for invasive cervical cancer, independently of their respective prevalences. METHODS: We performed meta-analyses of published observational studies and estimated pooled odds ratios with random-effects models for 32 HPV genotypes, using HPV-16 as the reference. RESULTS: Twenty-seven studies yielded 9,252 HPV-infected women: 2,902 diagnosed with invasive cervical cancer and 6,350 with normal cytology. Expressed as (odds ratio [95% confidence interval]), HPV-18 (0.63 [0.51, 0.78]) ranked closest to HPV-16, while other genotypes showed continuously decreasing relative oncogenic potentials: HPV-45 (0.35 [0.22, 0.55]), HPV-69 (0.28 [0.09, 0.92]), HPV-58 (0.24 [0.15, 0.38]), HPV-31 (0.22 [0.14, 0.35]), HPV-33 (0.22 [0.12, 0.38]), HPV-34 (0.21 [0.06, 0.80]), HPV-67 (0.21 [0.06, 0.67]), HPV-39 (0.17 [0.09, 0.30]), HPV-59 (0.17 [0.09, 0.31]), HPV-73 (0.16 [0.06, 0.41]), and HPV-52 (0.16 [0.11, 0.23]). CONCLUSIONS: Our results support the markedly higher oncogenic potentials of HPV-16 and -18, followed by HPV-31, -33, -39, -45, -52, -58 and -59, and highlight the need for further investigation of HPV-34, -67, -69 and -73. Overall, these findings could have important implications for the prevention of cervical cancer.

RESUMEN

The French high council of public health has recently amended age for HPV vaccination. The paper will describe reasons that have contributed to the development of these new guidelines. Parental and adolescent acceptance of HPV vaccination is reported as well as potential barriers among medical practices. First results of immunogenicity of vaccines using alternative dosing schedules are presented. Finally, preliminary data on clinical efficacy of the quadrivalent vaccine on genital warts and cervical precancerous lesions are presented. A decrease in the prevalence of infection with genotypes included in the vaccine has now been reported in several studies. This decrease may be partly attributable to herd immunity.

RESUMEN

BACKGROUND: In the Lao People's Democratic Republic (Lao PDR), cervical cancer is the third leading cause of women cancer. AIMS: The objective of this cross-sectional study was to compare the efficacy of careHPV™ test versus conventional Pap smear or Siriraj liquid-based cytology in the detection of cervical cancer in women living with human immunodeficiency virus type 1 (HIV-1). MATERIALS & METHODS: Overall, 631 women consented to participate. Four cervical specimens were taken for the purpose of conventional Pap smear, Siriraj liquid-based cytology, careHPV™ test, and HPV-16 genotyping. The exact McNemar test was used to compare the efficacy and diagnostic performance of the tests. RESULTS: Of the 631 women with follow-up, 331 were human papillomavirus (HPV) negative. High-grade squamous intraepithelial lesions were found in 37 women, biopsy-proven high-grade cervical intraepithelial neoplasia in 50 women, and invasive carcinoma in seven women. The proportion of women with high-grade cervical lesion or carcinoma detected after abnormal careHPV™ test was higher (6.02%; 95% confidence interval [CI]: 4.4-8.1) than that detected by conventional Pap smear (4.59%; 95% CI: 3.2-6.5). careHPV™ and HPV-16 genotyping had, respectively, the highest sensitivity (80.8%; 95% CI: 67.4-89.5) and specificity (92.2%; 95% CI: 89.8-94.2). HPV-16 was the most frequently detected genotype. CONCLUSIONS: careHPV™ test represents a screening option in Lao PDR, particularly in women living with HIV-1 because of higher prevalence of chronic HPV in this population.

RESUMEN

We studied the penetration of raltegravir and HIV shedding in the genital tract among 14 HIV-1-infected women receiving a raltegravir-containing regimen who had <40 copies/ml blood plasma (BP) HIV RNA. None of the cervicovaginal fluid (CVF) samples showed detectable HIV RNA. Median raltegravir concentrations were 235 ng/ml in BP and 93 ng/ml in CVF, with a CVF/BP ratio of approximately 2.3. This good penetration of raltegravir may contribute to the control of viral replication in the female genital tract.

RESUMEN

The French National reference Laboratory for Human papillomavirus (HPV) performed in 2009 a national study in order to review the methods used to detect and identify HR HPV genotypes in microbiology laboratories. Results from this study show a great diversity in volumes of samples treated in laboratories. Among clinical indications, the most frequent is a result of ASC-US at a Pap smear. This indication in the only one covered by the National Public Insurance System and is mostly performed in laboratories from private sector. Other indications mainly correspond to research programs and are performed in public Hospitals. This study allowed also to review the adequacy between the liquid based cytology samples and the assays used for direct detection of HR HPV or identification of the genotypes present in the sample. The right tests were not carried in the right solution storage according to the recommendations from different HPV testing assays. National recommendations should be elaborated in order to improve the performance of the test used.

RESUMEN

Head and neck squamous cell carcinomas (HNSCC) are the seventh most frequent cancers. Among HNSCCs, oral squamous cell carcinomas (OSCCs) include several anatomical locations of the oral cavity, but exclude the oropharynx. The known risk factors for OSCCs are mainly alcohol consumption and tobacco use for at least 75-80% of cases. In addition to these risk factors, Human papillomavirus (HPV) types 16 and 18, classified as high-risk (HR) HPV genotypes, are considered as risk factors for oropharyngeal cancers, but their role in the development of OSCC remains unclear. We tested the hypothesis of viral etiology in a series of 68 well-characterized OSCCs and 14 potentially malignant disorders (PMD) in non-smoking, non-drinking (NSND) patients using broad-range, sensitive molecular methodologies. Deep-sequencing of the transcriptome did not reveal any vertebrate virus sequences other than HPV transcripts, detected in only one case. In contrast, HPV DNA was detected in 41.2% (28/68) and 35.7% (5/14) of OSCC and PMD cases, respectively. Importantly, 90.9% (30/33) of these belonged to the Betapapillomavirus genus, but no viral transcripts were detected. Finally, high-throughput sequencing revealed reads corresponding to transcripts of the Trichomonas vaginalis virus (TVV), which were confirmed by RT-PCR in two OSCCs. Our results strongly suggest that Alphapapillomavirus genotypes classified as HR are not involved in the development of OSCCs in NSND patients and that known oncogenic infectious agents are absent in these specific OSCCs. Any possible direct or indirect role of Betapapillomavirus genus members and TVV in OSCCs remains speculative and requires further investigation.

RESUMEN

Human papillomaviruses (HPVs) are responsible for >99% of cervical cancers. Molecular diagnostic tests based on the detection of viral DNA or RNA have low positive predictive values for the identification of cancer or precancerous lesions. Triage with the Papanicolaou test lacks sensitivity; and even when combined with molecular detection of high-risk HPV, this results in a significant number of unnecessary colposcopies. We have developed a broad-range detection test of HPV transcripts to take a snapshot of the transcriptome of 16 high-risk or putative high-risk HPVs in cervical lesions (HPVs 16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, 66, 68, 73, and 82). The purpose of this novel molecular assay, named HPV RNA-Seq, is to detect and type HPV-positive samples and to determine a combination of HPV reads at certain specific viral spliced junctions that can better correlate with high-grade cytology, reflecting the presence of precancerous cells. In a proof-of-concept study conducted on 55 patients, starting from cervical smears, we have shown that HPV RNA-Seq can detect papillomaviruses with performances comparable to a widely used HPV reference molecular diagnostic kit; and a combination of the number of sequencing reads at specific early versus late HPV transcripts can be used as a marker of high-grade cytology, with encouraging diagnostic performances as a triage test.

RESUMEN

BACKGROUND: Cervical cancer screening might contribute to the prevention of anal cancer in women. We aimed to investigate if routine cervical cancer screening results-namely high-risk human papillomavirus (HPV) infection and cytohistopathology-predict anal HPV16 infection, anal high-grade squamous intraepithelial lesions (HSIL) and, hence, anal cancer. METHODS: We did a systematic review of MEDLINE, Embase, and the Cochrane library for studies of cervical determinants of anal HPV and HSIL published up to Aug 31, 2018. We centrally reanalysed individual-level data from 13 427 women with paired cervical and anal samples from 36 studies. We compared anal high-risk HPV prevalence by HIV status, cervical high-risk HPV, cervical cytohistopathology, age, and their combinations, using prevalence ratios (PR) and 95% CIs. Among 3255 women with anal cytohistopathology results, PRs were similarly calculated for all anal HSIL and HPV16-positive anal HSIL. FINDINGS: Cervical and anal HPV infections were highly correlated. In HIV-negative women, anal HPV16 prevalence was 41% (447/1097) in cervical HPV16-positive versus 2% (214/8663) in cervical HPV16-negative women (PR 16·5, 95% CI 14·2-19·2, p<0·0001); these values were 46% (125/273) versus 11% (272/2588) in HIV-positive women (4·4, 3·7-5·3, p<0·0001). Anal HPV16 was also associated with cervical cytohistopathology, with a prevalence of 44% [101/228] for cervical cancer in HIV-negative women (PR vs normal cytology 14·1, 11·1-17·9, p<0·0001). Anal HSIL was associated with cervical high-risk HPV, both in HIV-negative women (from 2% [11/527] in cervical high-risk HPV-negative women up to 24% [33/138] in cervical HPV16-positive women; PR 12·9, 95% CI 6·7-24·8, p<0·0001) and HIV-positive women (from 8% [84/1094] to 17% [31/186]; 2·3, 1·6-3·4, p<0·0001). Anal HSIL was also associated with cervical cytohistopathology, both in HIV-negative women (from 1% [5/498] in normal cytology up to 22% [59/273] in cervical HSIL; PR 23·1, 9·4-57·0, p<0·0001) and HIV-positive women (from 7% [105/1421] to 25% [25/101]; 3·6, 2·5-5·3, p<0·0001). Prevalence of HPV16-positive anal HSIL was 23-25% in cervical HPV16-positive women older than 45 years (5/20 in HIV-negative women, 12/52 in HIV-positive women). INTERPRETATION: HPV-based cervical cancer screening programmes might help to stratify anal cancer risk, irrespective of HIV status. For targeted secondary anal cancer prevention in high-risk groups, HIV-negative women with cervical HPV16, especially those older than 45 years, have a similar anal cancer risk profile to that of HIV-positive women.

RESUMEN

BACKGROUND: The aim of this study was to describe the experience of pregnant and non-pregnant HIV-infected women regarding fertility and childbearing, with a view to inform policies and practices to improve reproductive outcome. METHODS: A cross-sectional survey collected information on socio-demographic and basic reproductive characteristics of HIV-infected women in Europe. A total of 403 women participated; 121 were pregnant. RESULTS: The median age was 29 years and 84% (228) of women were born in Europe. Overall 68% (275 of 403) had been pregnant at some time. At the time of the survey, 59% (n = 160) of women had no HIV symptoms; severe symptoms were more frequent among non-pregnant than pregnant respondents (36% (65 of 181) versus 5% (4 of 88)). Of the women, 80% reported being in a long-standing relationship; 39% (74 of 190) reported that they became infected by their current partner and, overall, heterosexual infection was reported as the mode of acquisition in 55% (190 of 344). Maternal well-being, no previous live birth and having an uninfected partner were strongly associated with the likelihood of being pregnant. To assess the problems relating to fertility, pregnant and non-pregnant women were considered separately. Overall, 46% of pregnant women reported not using condoms to protect against infection during pregnancy. Of the 60 pregnant women who planned their pregnancies, 10 reported the need for assistance in conceiving: five monitored their ovulation period and five became pregnant through in vitro fertilization. Of 34 non-pregnant women currently trying for a baby, 15 (44%) had done so for more than 18 months. Overall 25 (27%) of 94 women who planned to become pregnant needed reproductive care. CONCLUSIONS: Our results suggest that these days knowledge of HIV infection neither influences the desire for children nor the decisions regarding pregnancy in HIV-infected women living in Europe.
