Attitudes and Practices of Primary Care Physicians in the UCSF/Stanford Collaborative Research Network * BACKGROUND We hoped to determine the attitudes and practices of primary care physicians regarding the use [...]

ABSTRACTThe immune function test is an integrated measure of total mitogen-inducible CD4+T cell metabolic activity in the peripheral blood, and it is used to guide the dosing of immunosuppressive medications after solid organ transplantation. Recently, low CD4+T cell metabolic activity due to pharmacologic immunosuppression has been linked to rapidly progressive cirrhosis in hepatitis C virus (HCV)-infected liver transplant recipients. We speculate that either cirrhosis or HCV might adversely affect the CD4+T cell reactivity even in the absence of immunosuppressive medications. We thus performed this assay on a cohort of untransplanted hepatology patients who were not taking immunomodulatory drugs. Low mitogen-stimulated CD4+T cell metabolic reactivity was more commonly seen in untransplanted patients with HCV cirrhosis or with cirrhosis due to other causes but not in control patients or in those with chronic HCV in the absence of cirrhosis. The lowest mean CD4+T cell reactivities were seen in patients with both cirrhosis and HCV. Caution should be exercised when immune function test results are used to guide immunomodulatory therapy in transplant recipients with suspected cirrhosis, as low immune function test results may be a consequence of hepatic cirrhosis or of pharmacologic immunosuppression.

Objectives. The objectives of this study were to assess racial/ethnic trends in surveillance data in four states—California, New York, Florida and Texas, identify structural barriers to and facilitators of access to HIV pharmaceuticals by individuals in Medicaid and the AIDS Drug Assistance Program (ADAP), and identify treatment education and outreach efforts responding to the needs of ethnic minority HIV patients.Methods. State surveillance and claims data were used to assess trends by race/ethnicity in AIDS cases and mortality as well as participation rates in Medicaid and ADAP. Key informant interviews with state program administrators and local clinic-based benefit eligibility workers were used to identify social and policy barriers to and facilitators of access to HIV drugs and state strategies for overcoming racial/ethnic disparities.Results. Racial/ethnic disparities in the reduction of AIDS-related mortality were identified in three of the four states studied. Policy barriers included Medicaid requirements for legal immigration status and residency, limits on Medicaid eligibility based on disability requirements, and state-imposed income and benefit limits on ADAP. Social barriers to accessing AIDS medications included lack of information, distrust of government, and HIV-related stigma. State strategies for overcoming disparities included contracting with community-based organizations for treatment education and outreach, the use of regional minority coordinators, and public information campaigns.Conclusions. State policies play a significant role in determining access to HIV drugs, and state policies can be used to reduce racial/ethnic disparities in pharmaceutical access. Overall, eliminating racial/ethnic disparities in access to HIV pharmaceuticals appears to be an achievable goal.
