Universal HIV Testing of All Pregnant Women • 1998 Institute of Medicine recommended universal routine HIV testing with the right of refusal for all pregnant women in the US. • CDC plans to recommend a second test offered in third trimester. • ACOG recommends universal testing and third trimester testing in high risk women (Nov 2004)
Elizabeth: pregnant HIV+ • 19 year old Hispanic female, diagnosed with HIV when 17 yrs (April, 2003) in a family planning clinic when she presented with a discharge which was positive for Chlamydia. • She has been in your care since that time. She has not been on ART due to poor adherence with apts. • She presents with a complaint of delayed menses.
Timing of Transmission 1/3 Antepartum (in utero) 2/3 peripartum 1 2 3 Birth
Obstacles to Good Care for Women with HIV • Not going to clinic • Poverty (can’t afford, can’t get to clinic, other pressing priorities) • Forget to take medications • Poor support system • Depression • History of abuse • Chemical Dependency (current alcohol and drug use) • Housing instability • Distrust/ Lack of disclosure
Gender Issues and Adherence • Depression • Alcohol • Mental health Treatment • Low Educational Level • Unemployment • Absence of Social worker in Clinical center
Late Testing Results in Missed Opportunitiesfor Treatment and Prevention of HIV
Importance of HIV Diagnosis • Benefits to individual • Influencing the course of infection • Prevention of opportunistic infections • Prevention of morbidity • Prevention of mortality • Benefits to others • Prevention of transmission • Ability to care for others

Linking Person with HIV to Care • One third of individuals aware of their HIV infection are not receiving care • Possible reasons: • Fear, denial, stigma • Substance use, mental illness • Unaware of availability of care and treatment • Lack of care programs • Difficulty in access: e.g. financial barriers, distance

Epidemiology of HIV in U.S. • marginalized populations • Blacks = 50% of all new HIV/AIDS cases in 2003 • AIDS cases 1999-2003 • blacks, Latinos, whites • 15% women, 1% men • After AIDS dx, survival lowest in IDUs CDC
Injection Drug Use and HIV in the US • 1.5 million injection drug users • 800,000 in need of drug treatment • 120,000 in treatment programs • 10-30% with HIV disease • ~355,000 IDUs with HIV/AIDS • 100,00 receiving HIV care • Second highest risk for incident HIV infections • 25% new HIV infections
HIV and injecting drug use (2003) (55) No IDU reported (22) IDU without HIV (114) IDU and HIV Source: WHO Programme on Substance Abuse 98036-E-29 – 15 July 1998
Principles of Harm Reduction • Minimize harmful effects of drugs • Success not necessarily abstinence • Low threshold services • Patient vs. provider agenda • Addressing “non-medical” issues • Redefine health, goals, and success/failure
Risk (Harm) Reduction in Drug Users The chronic and relapsing pattern of drug misuse, wide array of serious medical consequences and increased HIV transmission risk require realistic, flexible and sustainable preventive risk reduction strategies. Risk reduction does not promote injection or non-parenteral drug use, but seeks to decrease the frequency of adverse events related to this practice. Successful risk reduction strategies are based on the underlying principle that injection and non-injection drug misuse is a medical illness which may not be cured in the individual or eliminated from society but can be conducted in a way that minimizes harm to the user and others. While complete cessation of drug use remains a laudable goal, reduction in drug use frequency and safer injection and non-injection practices is more realistic for many drug users until abstinence can be achieved.
