【 摘 要 】

Background

Since Highly Active Antiretroviral Therapy (HAART) medications were made available in 2002, multiple serious side effects have been observed. However, no study has yet systematically evaluated the prevalence of liver steatosis, a very serious but treatable side effect.

Objectives

This study examined the prevalence of and independent risk factors for liver steatosis in Chinese HIV-infected, HAART-experienced patients who had been diagnosed with hypertriglyceridemia.

Methods

In this cross-sectional observational study, the prevalence of liver steatosis was determined by ultrasound imaging that detected diffusion in hepatic echogenicity. The risk factors associated with steatosis were evaluated with a proportional odds logistic regression model.

Results

Among 163 HIV-infected patients with hypertriglyceridemia and past HAART experience, 75(46%) patients were determined to have liver steatosis. In multivariable logistic regression model, the risk factors associated with liver steatosis were: higher triglyceride level (OR = 1.086, P = 0.026), metabolic syndromes (OR = 2.092, P = 0.024) and exposure to nucleoside reverse transcriptase inhibitor (NRTIs) ((OR = 2.11, P = 0.001) and Stavudine (OR = 3.75, P = 0.01)). Exposure to Nevirapine (OR = 0 .41, P = 0.003) was a favorable factor for lipid metabolism in vivo and was a protective factors for liver steatosis.

Conclusions

Chinese HIV-infected patients with hypertriglyceridemia appear to be prone to liver steatosis, especially those on NRTIs. Routine screening should be considered on their lipid panels.
