Abstract:
Metabolic dysfunction‐associated steatotic liver disease (MASLD) is common in people with HIV (PWH). The morphological spectrum of MASLD compared to matched controls and of the correlation between the NAFLD activity score (NAS) and fibrosis stage in PWH remains unknown. Methods Overall, 107 liver biopsies from PWH with MASLD (MASLD‐PWH) were matched to 107 biopsies from individuals with MASLD and without HIV (MASLD controls) on age at biopsy, race/ethnicity, sex, type 2 diabetes, body mass index (BMI) and alanine aminotransferase (ALT) level. Biopsies were scored using NAS. Results Compared to MASLD‐controls, MASLD‐PWH had lower steatosis grade (OR: 0.65, 95% CI: (0.47–0.90), p = 0.01), lower lobular inflammation grade (OR: 0.55, 95% CI: (0.34–0.89), p = 0.02), less portal inflammation (OR: 0.42, 95% CI: (0.25–0.72), p = 0.002) and less ballooned hepatocytes (OR: 0.60, 95% CI: (0.41–0.88), p = 0.01). Thus, NAS was lower in MASLD‐PWH (OR: 0.69, 95% CI: (0.56–0.85), p 〈 0.001) than in MASLD controls. There was a trend towards lower prevalence of steatohepatitis in MASLD‐PWH (OR: 0.84, 95% CI: (0.68–1.03), p = 0.09). A multivariate analysis demonstrated that MASLD‐PWH cases had significantly less steatosis (OR: 0.66, p = 0.03), portal inflammation (OR: 0.34, p = 0.001) and ballooned hepatocytes (OR: 0.55, p = 0.01), yet higher stage fibrosis (OR: 1.42, p = 0.03) compared to MASLD controls. Conclusion The NAS and histological drivers of fibrosis (e.g. inflammation and hepatocyte ballooning) are less pronounced in MASLD‐PWH, and yet fibrosis stage was generally higher when compared to matched controls with MASLD without HIV. This suggests HIV‐specific factors beyond hepatic necroinflammation may contribute to fibrosis progression in MASLD‐PWH.
