Interleukin (IL)-18 is regulated by inflammasomes in response to pathogens and danger signals and has been implicated in both the pathogenesis of NAFLD and HIV disease progression. We hypothesized that increased IL-18 may be associated with NAFLD and liver injury in PWH. This was an observational study of 125 PWH and 59 individuals without HIV in the Boston area. Participants with known hepatitis B, hepatitis C, and excessive alcohol use were excluded. IL-18 was measured in serum by enzyme-linked immunosorbent assay. Liver lipid content was assessed by liver-to-spleen computed tomography (CT) attenuation ratio. Aspartate aminotransferase (AST), alanine aminotransferase (ALT), and IL-18 levels were higher in PWH than in controls. In PWH, log\n 10<\/jats:sub>\n IL-18 was associated with log\n 10<\/jats:sub>\n AST (\n r<\/jats:italic>\n \u2009=\u20090.34,\n p<\/jats:italic>\n \u2009=\u2009.0001), log\n 10<\/jats:sub>\n ALT (\n r<\/jats:italic>\n \u2009=\u20090.33,\n p<\/jats:italic>\n \u2009=\u2009.0002), log\n 10<\/jats:sub>\n HIV RNA (\n r<\/jats:italic>\n \u2009=\u20090.29,\n p<\/jats:italic>\n \u2009=\u2009.002), and inversely associated with liver-to-spleen ratio (\n r<\/jats:italic>\n \u2009=\u2009\u22120.24,\n p<\/jats:italic>\n \u2009=\u2009.02). In addition, log\n 10<\/jats:sub>\n IL-18 was associated with log\n 10<\/jats:sub>\n triglycerides (\n r<\/jats:italic>\n \u2009=\u20090.26,\n p<\/jats:italic>\n \u2009=\u2009.003), log\n 10<\/jats:sub>\n MCP-1 (monocyte chemoattractant protein-1;\n r<\/jats:italic>\n \u2009=\u20090.33,\n p<\/jats:italic>\n \u2009=\u2009.0004), log\n 10<\/jats:sub>\n caspase-1 (\n r<\/jats:italic>\n \u2009=\u20090.35,\n p<\/jats:italic>\n \u2009<\u2009.0001), log\n 10<\/jats:sub>\n LPS (\n r<\/jats:italic>\n \u2009=\u20090.28,\n p<\/jats:italic>\n \u2009=\u2009.004), and inversely associated with high-density lipoprotein (\n r<\/jats:italic>\n \u2009=\u2009\u22120.28,\n p<\/jats:italic>\n \u2009=\u2009.002), and CD4\n +<\/jats:sup>\n \/CD8\n +<\/jats:sup>\n T cell ratio (\n r<\/jats:italic>\n \u2009=\u2009\u22120.24,\n p<\/jats:italic>\n \u2009=\u2009.007). In controls without HIV, log\n 10<\/jats:sub>\n IL-18 was also associated with log\n 10<\/jats:sub>\n ALT (\n r<\/jats:italic>\n \u2009=\u20090.44,\n p<\/jats:italic>\n \u2009=\u2009.0005). After adjusting for potential confounders, the relationships between IL-18 and AST (\n p<\/jats:italic>\n \u2009=\u2009.004) and ALT (\n p<\/jats:italic>\n \u2009=\u2009.003) remained significant, and the relationship between IL-18 and liver-to-spleen ratio (\n p<\/jats:italic>\n \u2009=\u2009.02). Increased inflammasome activation and subsequent monocyte recruitment in PWH may contribute to the development and progression of NAFLD. Clinical Trials Registration.
