The study evaluated the clinical significance of splenomegaly as a marker of underlying liver disease in people with HIV. The results showed that splenomegaly was associated with a higher prevalence of ACLD and portal hypertension, suggesting its utility as a marker for further investigations.
Objectives To evaluate the clinical significance of splenomegaly as a marker of underlying liver disease in people with HIV (PWH). Methods We included consecutive PWH from a prospective cohort from 2010 to 2020 with available liver stiffness measurement (LSM) and liver imaging to define splenomegaly (> 13 cm) within 1 year. Cut-offs of LSM > 10 kPa and > 21 kPa were used to identify advanced chronic liver disease (ACLD) and portal hypertension, respectively. Logistic regression multivariable analysis was employed to identify independent predictors of ACLD. Results In all, 331 PWH were included, 76% of them men, with a median (interquartile range) age of 51.3 (45-58) years, all receiving antiretroviral treatment, and 53% were HIV monoinfected. The PWH with splenomegaly exhibited a higher prevalence of ACLD compared with those with normal spleen size, as per LSM (26% vs. 9%; p = 0.009). Portal hypertension diagnosed by LSM was also more prevalent in PWH with splenomegaly than in those without (15% vs. 2%; p < 0.001). Independent predictors of ACLD were viral hepatitis coinfection [adjusted odds ratio (aOR) = 3.15, 95% confidence interval (CI): 1.65-6.0], lower platelets (aOR = 0.99, 95% CI: 0.99-0.99) and splenomegaly (aOR = 2.41, 95% CI: 1.17-4.99). In patients with available oesophagogastroduodenoscopy, splenomegaly was also associated with higher prevalence of oesophageal varices and other endoscopic findings of portal hypertension (38% vs. 17%; p = 0.027). Conclusions Splenomegaly identified on routine imaging may have utility as a marker of ACLD and portal hypertension, prompting further investigations.
