RESUMEN

OBJECTIVES: The US Department of Veterans Affairs (VA) is the largest integrated health care provider for HIV-infected patients in the USA. VA data for HIV-specific clinical and quality improvement research are an important resource. We sought to determine the accuracy of using the VA Corporate Data Warehouse (CDW), a fully automated medical records database for all VA users nationally, to identify HIV-infected patients compared with a gold-standard VA HIV Clinical Case Registry (CCR). METHODS: We assessed the test performance characteristics of each of our CDW criteria-based algorithms (presence of one, two or all of the following: diagnostic codes for HIV, positive HIV laboratory tests, and prescription for HIV medication) by calculating their sensitivity (proportion of HIV-positive patients in the CCR accurately detected as HIV-positive by the CDW algorithm) and positive predictive value (PPV; the proportion of patients identified by the CDW algorithm who were classified as HIV-positive from the CCR). RESULTS: We found that using a CDW algorithm requiring two of three HIV diagnostic criteria yielded the highest sensitivity (95.2%) with very little trade-off in PPV (93.5%). CONCLUSIONS: A two diagnostic criteria-based algorithm can be utilized to accurately identify HIV-infected cohorts seen in the nationwide VA health care system.

RESUMEN

BACKGROUND: Hodgkin lymphoma (HL) incidence has increased since combined antiretroviral therapy (cART) introduction. It is unclear how different cART classes (e.g., protease inhibitors (PI), non-nucleoside reverse transcription inhibitors (NNRTI)) influence HL. This study aimed to determine the effects of cART duration on HL incidence among HIV-infected veterans. METHODS: We performed a retrospective cohort study utilizing the Veterans Affairs HIV Clinical Case Registry (1985-2010). HL cases were identified using ICD-9 codes (201.4-9). cART, PI, and NNRTI duration was the aggregate number of treatment days delivered. Incidence rates (IR) and rate ratios (IRR) were calculated from Poisson regression models to examine the effects of cART duration on HL. RESULTS: 31,576 cART users contributed 288,736 person-years (PY) and 211 HL cases (IR=7.3/10,000 person-years). HL incidence decreased from 25.1/10,000 PY (95%CI=18.9-33.4) within the first year of cART to 0.6/10,000 PY (95%CI=0.3-1.6) after ≥ 10 years. In multivariable models, each additional year of cART was associated with decreased HL incidence (IRR=0.80; 95%CI=0.75-0.86); similar effects were observed in models assessing HL incidence by PI and NNRTI. CONCLUSION: Our findings indicate long-term cART of any class is associated with decreased HL risk. High HL incidence directly following cART initiation supports a potential immune reconstitution mechanism in HIV-related HL. Further research is needed to evaluate the interaction between early cART, immune reconstitution, and HL.

RESUMEN

Individuals 50 years of age or older continue to account for at least 10% of AIDS cases reported to the Centers for Disease Control and Prevention in recent years. Little research is devoted to addressing the specific issues affecting diagnosis, treatment, and prevention of AIDS in older Americans. Survival rates among elderly individuals infected with human immunodeficiency virus (HIV) are consistently decreased in comparison with those for younger patients. Elderly individuals also are less likely to use a condom during sexual intercourse or to participate in routine HIV testing. This article reviews the current literature concerning the changing epidemiology of AIDS among older Americans. The article also addresses AIDS-related morbidity and mortality, treatment issues, and HIV-prevention behaviors among the elderly. Enhanced clinician awareness of HIV in the elderly, along with further research concerning HIV treatment and prevention, is necessary to improve survival and outcome for those patients.
