RESUMO
BACKGROUND: Assisted reproductive technology (ART) with washed semen can achieve pregnancy with minimal risk of horizontal and vertical transmission of chronic viral diseases (CVD) such as human immunodeficiency virus (HIV), hepati- tis C virus (HCV) and hepatitis B virus (HBV) among serodiscordant couples. How- ever, few studies have been made of the use made by these couples of ARTs or of the obstetric results achieved. MATERIALS AND METHODS: In this retrospective study, 93 men who were seropositive for HIV, HCV or HBV and who underwent assisted reproduction treatment at our centre (Hospital Universitario Virgen de las Nieves, Granada, Spain) were included. Washed semen was tested to detect viral particles. Non-infected women were tested before and after each treatment, as were the neonates at birth and after three months. RESULTS: A total of 62 sperm samples were washed, and none were positive for the detec- tion of viral molecules. Semen samples from 34 HBV positive males were not washed since the female partner had immunity to hepatitis B. In total, 38 clinical pregnancies were achieved (22% per cycle and 40.9% per couple) out of 173 cycles initiated, and 28 births were achieved (16.2% per cycle and 30.1% per couple), producing 34 live births. The rate of multiple pregnancies was 21.4%. Obstetric and neonatal results were similar in the groups of couples studied. At follow-up, no seroconversion was detected in the women or neonates. CONCLUSION: Sperm washing and intracytoplasmic sperm injection are shown to be a safe and effective option for reducing the risk of transmission or super infection in serodiscordant or concordant couples who wish to have a child. Pregnancies ob- tained by ART in couples when the male is CVD infected achieve good obstetric and neonatal results.
RESUMO
BACKGROUND AND OBJECTIVES: To analyze the prevalence of human papillomavirus (HPV) genotypes and anal dysplasia in a cohort of human immunodeficiency virus (HIV) infected men who have sex with men (MSM) from southern Spain, and the variables associated with the appearance of dysplastic lesions and oncogenic HPV genotypes. PATIENTS AND METHODS: A cross-sectional study involving a prospective cohort of HIV-positive MSM included consecutively after signing an informed consent form. During the consultation 2 samples were taken from the anal mucosa: one for HPV detection using polymerase chain reaction (PCR), and the other for cytological evaluation; the Bethesda system was used to classify the cytology. RESULTS: One hundred and thirty-four consecutive patients were included. 91.1% patients were colonized by HPV, 66.1% by high-grade types and 41.52% by genotypes of low and high-grade malignancy. The most prevalent genotypes were: 6, 11, 16, 18, 51 and 53. 72.2% samples sent for cytology showed dysplasia, of which 71.4% were low-grade squamous intraepithelial lesions, 23.1% were atypical squamous cell, and 0% was high-grade squamous intraepithelial lesions. The multivariate analysis of risk factors associated with the appearance of dysplasia revealed association with smoking (95% confidence interval [95% CI] 1.196-9.303; odds ratio [OR] 3.336; P=.02) and number of oncogenic HPV types (95% CI 1.387-3.811; OR 2.229; P=.001). With regard to the presence of oncogenic HPV genotypes the multivariate analysis showed a high CD4 cell count was a protective factor against infection by these viruses (95% CI 1.098-5.58; OR 2.48; P=.029). CONCLUSIONS: The prevalence of anal dysplasia among HIV-positive MSM in this study is very high, fundamentally in smokers and a high number of oncogenic HPV genotypes. The presence of oncogenic HPV genotypes was associated with a lower CD4 cell count.
