United States Clinical Experience with Assisted Reproductive Technology in HIV-discordant Couples Mark V. Sauer, MD Professor Department of Obstetrics & Gynecology Columbia University New York, New York
Scope of the Problem • Nearly one million Americans are infected with HIV • Most HIV-seropositive individuals are of reproductive age • Heterosexual contact greatest risk factor in women • Many infected men and women desire to have biologic offspring • “Safe sex” recommended for prevention, but also prevents pregnancy CDC. HIV/AIDS Surveillance Report 2003 Family Planning Perspectives 2001; 33:144-152.
Changing Attitude and Outlook • HAART enhances longevity and quality of life • Compliant patients remain healthy for many years following diagnosis • Disease now considered a chronic illness rather than terminal disease • Improved awareness of epidemic • Increased social acceptance • Emphasis on maintaining productive “normal” lives of infected patients
Hurdles to Fertility Care • Lack of meaningful published reports defining safety • No RCTs regarding methodology, safety or efficacy • No short or long term follow-up of children or families • CDC recommendation against treatment • State laws that assign criminal penalties • Insurance contracts may preclude HIV-seropositive patients • Perceived liabilities of engaging in care • Malpractice • Discrimination lawsuits vs conscientious objectors • Patient concerns regarding cross-contamination • Civil and criminal penalties
Clinical and Basic Science Support • Clinical science: large series reports attesting to general safety • Over 3,000 washed insemination cycles reported without infection • Nearly 1,000 IVF cycles reported without infection • Basic science: defining relationship of virus to reproductive tract tissues • Transmission through cellular elements in semen or free virus in fluids • Viral cultures of semen commonly positive (10-20%) • Compartmentalization in reproductive tract tissues may occur • Sperm lack CD4 receptor and may not harbor virus • HIV rarely if ever detected from the most motile washed fraction used in ART • Sperm surface membrane may allow alternative pathway for HIV gp120 binding (GalAAG pathway) but remains unsubstantiated Reprod Biomed Online 2005; 10:135-140.

Applying Essential Principles of Medical Ethics • Autonomy • Informed rationale decisions • Alternatives to treatment offered • Individuals may participate or withdraw • Non-maleficence • No evidence of needless harm • Harm may result from “omission” of care • Beneficence • Protects women and children • Enhances quality of life • Justice • Fair distribution of accessible services Am. J. Bioethics 2003; 3:33-40.

Columbia University IVF/ICSI Program Goals • To provide HIV serodiscordant couples an opportunity to safely have a child through assisted reproduction using IVF/ICSI • Access to a common procedure available throughout the U.S. • Provide a therapy that doesn’t cross legal boundries of “insemination” • Decrease the time to pregnancy, and number of needed exposures by ART • To gather data to further understand the needs of HIV seropositive patients seeking fertility assistance • Social, demographic, medical and reproductive database • Follow up of families and individuals treated • To report ongoing experience to patients and professional peers in hope of changing attitudes and reducing prejudice • Encourage development of new programs • Seek professional collaboration within REI and other disciplines

Importance of Advanced Directives • Written and witnessed consent for the disposition of fresh and cryopreserved specimens and embryos • Clear and convincing evidence of intent of the deceased party in the absence of a written directive. Such evidence must be personally witnessed by the physician involved with the procurement of the gametes or embryos. Ethics Committee Columbia Presbyterian Medical Center 2002
Columbia University Results • Interesting case reports • Reversible iatrogenic azospermia secondary to prescribed androgen use • Posthumous reproduction following the death of a life-partner Obstet Gynecol 2003; 101:1073-1075. Am J Obstet Gynecol 2002; 185:252-253.
Initiating a Program for Women with HIV • Opportunity for HIV seropositive women to access fertility care • Pre-cycle testing the same as conventional infertility patients • Additional requirements • MFM and ID medical clearance • Maintain minimally detectable titers • Initiate HAART prior to pregnancy and maintain throughout pregnancy • Patent tubes: COH and IUI • Failed IUI or women with tubal obstruction: IVF/ICSI
Initiating a Program for Women with HIV • Clinical activity began in 2002 • IUI of patients with patent fallopian tubes • IVF request initially turned down by CPMC ethics committee • Initial 3 patients treated with COH/IUI • All 3 women pregnant within 4 treatment cycles • All newborns HIV seronegative • IVF-ICSI initiated 2004 • 3 patients treated; 2 ongoing pregnancies • 7 patients screened and preparing to begin therapy
A Role for Assisted Reproduction? • Persons with HIV cannot be refused medical treatment unless objective scientific evidence demonstrates a significant risk of infection. • Americans with Disabilities Act • ART should not be denied to HIV-infected couples solely on the basis of their positive status • ACOG Committee Opinion 235, 2001
Summation: American Experience • Although various techniques using washed insemination methods are available, predominant ART used in U.S. has been IVF-ICSI • Few centers are currently offering ART to HIV seropositive patients • Multidisciplinary approach best for providing integrated care by internists, reproductive endocrinologists, maternal fetal medicine specialists, social workers and skilled laboratory personnel • Despite endorsement for treatment by ASRM and ACOG, the CDC continues to recommend against insemination methods
Conclusion: American Experience • A slow but growing clinical experience and published literature by U.S. centers has emerged regarding reproductive care for HIV infected patients • State laws and concerns related to civil, professional and criminal liability have hindered wide-spread introduction of methods of treatment • Studies needed to address the growing needs of HIV infected patients • Uniformity of approach to care • Criteria for treatment • Outcome tracking • Multicenter collaboration both nationally and internationally
