HIV, hepatitis B and hepatitis C and infertility: reducing risk

In vitro fertilization when men, women, or both partners are positive for HIV: a case-control study

PURPOSE

The aim of this study was to compare the outcomes of in vitro fertilization (IVF) for couples where one or both partners were positive for the human immunodeficiency virus (HIV) to matched control couples.

METHODS

A matched case-control retrospective study was performed. Data for 104 couples where the woman was HIV-positive; for 90 couples where the man was HIV-positive; and for 33 couples where both partners were HIV-positive were prospectively analyzed in comparison to matched controls treated in our center during the same period. The main outcomes were clinical pregnancy and live birth rates.

RESULTS

For couples involving an HIV-positive man, clinical outcomes were comparable to controls and resulted in the birth of 18 healthy babies after 90 cycles. When the woman was affected, cycle cancelation, number of retrieved oocytes, and on-going clinical pregnancy rates per transfer were statistically reduced. Implantation rates were comparable to those of non-affected controls. Seven healthy babies for 104 cycles were obtained. For a couple in which both partners were HIV-positive, only one healthy birth occurred after 33 cycles. Pregnancy rates were systematically reduced though not significantly probably due to sample size.

CONCLUSIONS

Our data suggest that IVF outcomes were similar to controls when men were HIV-positive and remain acceptable when women were HIV-positive. IVF outcomes were severely reduced in our sero-concordant couples; however, many patients had severe HIV disease previously, and therefore, these results should be reassessed in patients treated early in their disease.

Hepatitis B virus infection and pregnancy: a practical approach

Hepatitis B virus (HBV) infection is a global problem and the world has 350 million carriers of chronic hepatitis B. Over 50 % of these have acquired their infection vertically from their mothers (mother-to-child transmission [MTCT]). Majority (>90 %) of vertically-acquired infection results into chronic infection, due to induction of an immune-tolerant state. Hence, management of chronic HBV during pregnancy and strategies to prevent MTCT would go a long way in global control of HBV infection and the morbidity and mortality associated with it. However, chronic HBV infection in pregnancy presents a unique challenge, because of existence of a complex relationship between the physiological changes of pregnancy and the pathophysiological response of body to HBV. This relationship may lead to a varied presentation of the patient to the doctor depending on the period of her pregnancy and stage of her liver disease. Each of these modes of presentation raises issues that need to be addressed for successful maternal and fetal outcome, including prevention of MTCT of HBV. This review will try to give a practical approach in addressing these issues.

A decade of the sperm-washing programme: where are we now?

Since 1999, we have treated HIV-positive men with sperm washing as part of a risk-reduction programme with a year-on-year increase in total infectious cycles performed to over 200 in 2008. Four hundred and thirty nine cycles of IUI, 114 cycles of IVF and 117 cycles of ICSI have been performed in HIV positive men over the decade and of the 259 couples treated, a pregnancy rate and ongoing pregnancy rate per couple of 45.4% and 36.3% have been achieved with over 100 children born with no seroconversions. We outline the continued importance of such risk-reduction measures with 9.7% of samples from men with 'stable' disease on anti-retroviral treatment and undetectable viral load demonstrating detectable viral particles in seminal fluid and discuss measures to improve outcome in this patient group.

Fathers and HIV: considerations for families

BACKGROUND

Fathers are intricately bound up in all aspects of family life. This review examines fathers in the presence of HIV: from desire for a child, through conception issues, to a summary of the knowledge base on fathers within families affected by HIV.

METHODS

A mixed-methods approach is used, given the scarcity of literature. A review is provided on paternal and male factors in relation to the desire for a child, HIV testing in pregnancy, fatherhood and conception, fatherhood and drug use, paternal support and disengagement, fatherhood and men who have sex with men (MSM), and paternal effects on child development in the presence of HIV. Literature-based reviews and systematic review techniques are used to access available data Primary data are reported on the issue of parenting for men who have sex with men.

RESULTS

Men with HIV desire fatherhood. This is established in studies from numerous countries, although fatherhood desires may be lower for HIV-positive men than HIV-negative men. Couples do not always agree, and in some studies, male desires for a child are greater than those of their female partners. Despite reduced fertility, support and services, many proceed to parenting, whether in seroconcordant or serodiscordant relationships. There is growing knowledge about fertility options to reduce transmission risk to uninfected partners and to offspring.Within the HIV field, there is limited research on fathering and fatherhood desires in a number of difficult-to-reach groups. There are, however, specific considerations for men who have sex with men and those affected by drug use. Conception in the presence of HIV needs to be managed and informed to reduce the risk of infection to partners and children. Further, paternal support plays a role in maternal management.

CONCLUSIONS

Strategies to improve HIV testing of fathers are needed. Paternal death has a negative impact on child development and paternal survival is protective. It is important to understand fathers and fathering and to approach childbirth from a family perspective.

Infertility Treatment for HIV-Positive Women

Thanks to antiretroviral combination therapy, HIV-infected individuals live longer, healthier lives and may wish to have children. Women with HIV can attempt to conceive naturally or through simple self-insemination to minimize the risk of horizontal HIV transmission. Assisted reproduction technology is necessary in couples with infertility, which can either be independent of HIV infection and its treatment or be associated with it. This article summarizes the latest evidence regarding the desire for a child in HIV-positive women and how HIV infection and its treatment may impact female fertility. Current data regarding access to and outcomes of assisted conception programs in HIV-positive women wishing to conceive in both high- and low-income countries is also reviewed.

HIV and reproductive care—a review of current practice

In developed countries, antiretroviral treatment has increased life quality and expectancy of HIV-infected individuals and led to a drop in mother-to-child transmission (MCT) risk to below 1%. Fertility has been shown to be reduced in both men and women with HIV. As a result of these factors, the demand for reproductive care in this population is rising. In discordant couples where the man is positive, sperm washing significantly reduces viral transmission risk to the uninfected female partner over unprotected intercourse. Positive women do not necessarily need specialised fertility treatment but should be monitored closely during pregnancy to minimise MCT risk.

Human immunodeficiency virus infection and fertility care in the United Kingdom: demand and supply

OBJECTIVE

To collect data on the demand and provision of fertility care in HIV-infected couples in the United Kingdom and data on the etiology of subfertility in this population.

DESIGN

A postal questionnaire survey and audit of causes of infertility in HIV-infected women.

SETTING

Seventy-four Human Embryology and Fertilisation Authority-registered assisted conception units (ACUs) and 294 genitourinary medicine (GUM) clinics in the United Kingdom were sent questionnaires.

PATIENT(S)

Sixty-five HIV-infected women attending the Research Clinic at the Chelsea and Westminster ACU.

INTERVENTION(S)

None.

MAIN OUTCOME MEASURE(S)

Number of ACUs treating HIV-infected patients and number of GUM clinics receiving requests for referral, as well as the etiology of subfertility in HIV-infected women attending our clinic.

RESULT(S)

Response rates from ACUs and GUM clinics were 93% and 63%, respectively. Fourteen ACUs (20%) were treating HIV-infected men; of these, seven (10%) performed sperm washing, but only two (3%) tested sperm for HIV after processing, before use. Nine units (13%) treated HIV-infected women, but only three ACUs (4%) had separate laboratories for handling potentially infected gametes or embryos. Of the 15,211 patients registered in 81 GUM clinics, 4% of the men and 16% of the women had requested advice on conceiving. An audit of the Chelsea and Westminster HIV fertility clinic demonstrated a 40% prevalence of tubal factor infertility in HIV-infected women.

CONCLUSION(S)

Demand is high, and set to increase, but current suboptimal practice in some centers is placing unaffected partners and the unborn child at risk of seroconversion.

Laboratory safety during assisted reproduction in patients with blood-borne viruses

For couples where one or both partners are infected with human immunodeficiency virus or hepatitis C, the doors to receiving fertility care are opening as a result of better antiviral medication, better long-term prognosis and consequent changes in attitude. In line with this, fertility centres electing to treat couples with blood-borne viral (BBV) infection need to re-examine their policies and procedures to ensure the safety of their staff and both non-infected and infected patients during assisted reproduction treatments. At a time when the European Tissue Directive aims to introduce quality standards for assisted reproduction throughout Europe, we highlight the risks involved when treating patients with known BBV infections and argue that safety cannot be met with any certainty unless samples from such patients are handled within a separate high security laboratory or laboratory area, technically adapted to ensure minimal cross-contamination risk to uninfected gametes and embryos.

Assessment of welfare of the child in HIV positive couples

BACKGROUND

Demand for assisted conception amongst HIV-infected couples is rising in parallel with increased efficacy of antiretroviral medication which has improved life expectancy and reduced vertical transmission risk. There are no published data on welfare of the child assessment in HIV positive couples undergoing assisted conception.

METHODS

We assessed welfare of the child in 131 (i.e. total number seen, not treated) couples, where one or both partners were infected with HIV and referred to the infertility clinic at Chelsea and Westminster Hospital since 1999. In total, 59 couples received sperm washing treatment (male partner infected) resulting in 17 healthy babies, and 14 couples were treated in the female positive programme (5 concordant and 9 discordant for HIV) resulting in three healthy babies.

RESULTS

Issues surrounding welfare of the child were commonly encountered in this series and were significant enough to withhold treatment in five cases. Many were relationship issues surrounding acquisition of infection, fear of infection in the negative partner or child (n = 1), poor prognosis (multiple drug resistance) (n=3) or disability related to infection (n = 1).

CONCLUSIONS

Welfare of the child in HIV infected couples must be carefully considered in specialist centres with experienced counsellors. Issues surrounding treatment are complex and require close liaison with HIV specialists and involvement of the couple.
