PREVALENCE AND SEVERITY OF STEATOTIC LIVER DISEASE IN WOMEN WITH AND WITHOUT HIV.

INTRODUCTION: Steatotic liver disease (SLD) is highly prevalent in people with HIV (PWH) and is a major cause of morbidity and mortality in this population. However, it remains unclear whether SLD is influenced by HIV infection and whether the clinical management of PWH who have SLD should differ from non-HIV populations. METHODS: Liver steatosis and fibrosis were assessed using vibration-controlled transient elastography (VCTE) among 1,580 women (1,117 with HIV; 463 without) enrolled in the Women's Interagency HIV Study between 2013 and 2018. Steatosis was defined by a controlled attenuation parameter (CAP) ≥248 dB/m, and clinically significant fibrosis by liver stiffness ≥7.1 kPa. Participants were classified according to the AASLD diagnostic algorithm for SLD. Differences in fibrosis prevalence by HIV status were evaluated, and multivariable logistic regression was performed to identify factors associated with SLD and fibrosis, adjusting for age, ethnicity, BMI, alcohol use, diabetes, and smoking. RESULTS: Prevalence of SLD was 740 of 1580 (47%) and did not differ by HIV serostatus. Most SLD was metabolic dysfunction-associated steatotic liver disease (MASLD; 629 of 740 [82%]). HIV infection was associated with higher odds of clinically significant fibrosis only among women with SLD (adjusted OR 1.48, 95% CI 1.01-2.16, p=0.04; HIV*SLD interaction among entire cohort p=0.03). DISCUSSION: In this study, most SLD in women living with HIV is classified as MASLD. HIV infection is associated with higher odds of hepatic fibrosis only among those with SLD. Further work is needed to understand how HIV may potentiate fibrosis in the setting of SLD.
