Metabolic and morphological side-effects occur in HIV-infected individuals receiving anti-retroviral treatment (ART). Peripheral fat loss that occurs particularly in the face, limbs and/or buttocks is referred to as lipoatrophy and has been found to be highly stigmatizing and to adversely impact the health-related quality of life (HRQL).

BACKGROUND Substantial immunological improvement has been reported for HIV-infected patients who switch from a failing regimen to a protease inhibitor regimen with Lopinavir/ritonavir (LPV/r). We use decision analysis modeling to estimate health and economic consequences expected from this switch. METHODS A Markov model combined best evidence for CD4(+)(More)
Allergic or anaphylactic-like reactions have been reported with cis-dichlorodiammineplatinum(II) (CDDP) administration. We have seen two reactions among 50 patients treated in a phase II trial of CDDP. Both patients were successfully rechallenged after diphenhydramine pretreatment, and therapy was continued. In vivo and in vitro studies performed in one(More)
OBJECTIVE In patients with longstanding severe rheumatoid arthritis (RA) receiving chronic treatment with adalimumab, health related quality of life (HRQOL) was assessed using new instruments [Functional Assessment of Chronic Illness Therapy-Fatigue scale (FACIT-Fatigue) and Health Utilities Index Mark 3 (HUI3)] and a more conventional instrument [Medical(More)
BACKGROUND Markov models have been the standard framework for predicting long-term clinical and economic outcomes using the surrogate marker endpoints from clinical trials. However, they are complex, have intensive data requirements and are often difficult for decision makers to understand. Recent developments in modelling software have made it possible to(More)
OBJECTIVE To estimate the cost effectiveness and long-term combined effects of HIV disease and antiretroviral (ARV) therapy-related risk for coronary heart disease (CHD) on quality-adjusted survival and healthcare costs for ARV-experienced patients. METHODS A previously validated Markov model was updated and supplemented with the Framingham CHD risk(More)
BACKGROUND AND OBJECTIVE Selection of antiretroviral therapy (ART) for antiretroviral-experienced patients should involve balancing multiple factors, including clinical efficacy, adverse-event risk, resistance concerns, cost effectiveness and expected budget impact. The efficacy of a regimen and its durability, as demonstrated in controlled clinical trials,(More)
BACKGROUND The ARTEMIS trial compared first-line antiretroviral therapy (ART) with lopinavir/ritonavir (LPV/r) to darunavir plus ritonavir (DRV + RTV) for HIV-1-infected subjects. In order to fully assess the implications of this study, economic modelling extrapolating over a longer term is required. OBJECTIVE The aim of this study was to simulate the(More)
BACKGROUND This study examines the cost and consequences of initiating an ARV regimen including Lopinavir/ritonavir (LPV/r) or Efavirenz (EFV), using data from a recent clinical trial in a previously published model of HIV-disease. METHODS We populated the Markov model of HIV-disease with data from ACTG 5142 study to estimate the economic outcomes of(More)
Chronic hepatitis C virus (HCV) infection is an important public health issue owing to its worldwide prevalence and its profound effects on patients’ well-being and function. We developed a new patient self-report tool, the HCV patient-reported outcomes (HCV-PRO) instrument, to assess patients’ function and well-being reflecting both HCV disease and(More)
