Risk factors in human immunodeficiency virus/acquired immunodeficiency syndrome patients undergoing antiretroviral therapy in the state of Pernambuco, Brazil: a case-control study.

AbstractBACKGROUND:
Although human immunodeficiency virus (HIV)-associated lipodystrophy has been reported for more than a decade, there is still considerable uncertainty regarding the mechanisms involved in its pathogenesis.
METHODS:
A case-control study was performed that aimed to identify the risk factors for lipodystrophy in HIV/acquired immunodeficiency syndrome (AIDS) patients undergoing antiretroviral therapy in Pernambuco, Brazil.
RESULTS:
Between July and November, 2007, a total of 332 patients were enrolled in the study: 182 cases and 150 controls. The following factors were independently associated with lipodystrophy: Use of stavudine [odds ratio (OR), 4.0; 95% confidence interval (CI), 2.3-6.9], use of didanosine (OR, 1.8; 95% CI, 1.0-3.4), use of lopinavir/ritonavir for less than 3 years (OR, 0.5; 95% CI, 0.2-1.0) and use of nucleoside/nucleotide analogue reverse transcriptase inhibitors (NTRIs) for more than 3 years (OR, 2.9; 95% CI, 1.6-5.2). Other associated factors were: duration of antiretroviral therapy (OR, 4.3; 95% CI, 2.4-7.9) and duration of HIV infection (OR, 2.9; 95% CI, 1.8-4.7). There was no association with the use of protease inhibitor when it was adjusted for the use of NRTIs.
CONCLUSION:
In this study, factors related to antiretroviral therapy were the main risk factors for lipodystrophy, corroborating the literature, but the findings also point to the need for further exploration into some of these associations, especially with the use of didanosine and lopinavir/ritonavir, which are less frequently reported. Future studies with a larger number of patients and a prospective design could provide valuable information for understanding this disorder.
