Causes of death in hospitalised HIV-infected patients at a National Referral Centre in Singapore: a retrospective review from 2008 to 2010

ABSTRACT

<p><b>INTRODUCTION</b>Highly active antiretroviral therapy (HAART) has improved outcomes for individuals infected with human immunodeficiency virus (HIV). This study describes the causes of death in hospitalised HIV-positive patients from 2008 to 2010 in Tan Tock Seng Hospital, the national referral centre for HIV management in Singapore.</p><p><b>MATERIALS AND METHODS</b>Data were retrospectively collected from HIV-positive patients who died in Tan Tock Seng Hospital from January 2008 to December 2010.</p><p><b>RESULTS</b>Sixty-seven deaths occurred in the study period. A majority of patients died of non-acquired immune deficiency syndrome (AIDS)-defining illnesses (54.7%). The median CD4 count was 39.5 (range, 20.0 to 97.0), and 7 patients had HIV viral loads of <200 copies/mL. There were 27 deaths due to opportunistic infections, 27 due to non AIDS-defining infections, 4 due to non AIDS-associated malignancies. This study also describes 3 deaths due to cardiovascular events, and 1 due to hepatic failure. Patients who had virologic suppression were more likely to die from non AIDS-defining causes.</p><p><b>CONCLUSION</b>Causes of death in HIV-positive patients have changed in the HAART era. More research is required to further understand and address barriers to testing and treatment to further improve outcomes in HIV/AIDS.</p>
