ORGAN TRANSPLANTATION: PERSONS WITH DETECTABLE HIV VIRAL LOAD Margaret Ragni, MD University of Pittsburgh
HIV/HCV Co-Infected Patients Greater HCV RNA, liver fibrosis, ESLD • Increased hepatotoxicity, drug interactions • Reduced response to interferon/ribavirin • Reduced tolerance to HAART Thus, more likely to have detectable HIVviral load
HIV Viral Load: A Spectrum 1. HIV Disease Progression HIV RNA Disease Progression 2. HIV Transmission HIV RNASexual transmission 3. Survival HIV RNA Survival Spectrum: Not Black and White
HIV Viral Load: A Spectrum 1. HIV Disease Progression– AIM is undetectable HIV RNA REALITY is low set point slows progression (Mellors et al, Science, 1996) 2. HIV Sexual Transmission – AIM is undetectable HIV RNA REALITY is low set point reduce transmission (Ragni et al, JAIDS, 1998) 3. Survival– AIM is undetectable HIV RNA REALTY is low set point improves survival (Mellors et al, Ann Int Med, 1996) Spectrum: Not Black and White

RECOMMENDATIONS: OLTX Eligibility • Subjects with CD4 < 200/l • Subjects with detectable HIVviral load • Previously responsive to HAART • No longer able to tolerate HAART • Liver toxicity • Severe liver dysfunction • Drug interactions • Subjects with past opportunistic infections • Otherwise as above, once infection resolves
Other Unanswered Questions 1. Optimal Time for OLTX 2. Optimal Antiretroviral, Antirejection Drugs 3. Recurrence of HCV Infection in Transplanted Organ
Issues: Transplant in HIV Infection 1. Develop new treatment approaches for HCV 2. Determine risk factors for HCV progression 3. Determine risk factors for adverse outcome
Issues: Transplant in HIV Infection 1. Develop new treatment approaches for HCV Antiviral, anti-cytokine, anti-fibrotic drugs 2. Determine risk factors for HCV progression ETOH, Hep B, HIV, Hepatotoxins 3. Determine risk factors for adverse outcome Pancreatitis, drug interactions, anti-rejection,antiretroviral drugs
