BACKGROUND: Mean platelet volume (MPV) has been reported significantly higher in patients with metabolic dysfunction associated steatotic liver disease (MASLD), suggesting a thrombogenic effect with an inconclusive link to excess risk for cardiovascular disease (CVD). The aim of this cross-sectional study was to elucidate the role of MPV in MASLD and review the literature. METHODS: A cohort of consecutive biopsy-proven MASLD patients was retrospectively investigated for possible associations of MPV with histological features of the disease and, separately, with patients' estimated risk for CVD. CVD Risk was assessed with three different scores: QRISK2, HellenicSCORE II and NAFLD CV Risk. Laboratory investigation included calculation of insulin resistance with the Homeostasis Model Assessment (HOMA) and measurement of serum adiponectin in a subgroup of patients. RESULTS: In a total of 139 MASLD patients, 56 (40.3%) with advanced fibrosis (F3/F4) steatohepatitis were included. MPV exceeded the upper limit of normal (=10 fl) in a significant proportion of study participants (n = 28.1%), with an overall mean of 9.4 ± .9 fl. Statistically significant associations of MPV with platelet count (Pearson correlation, p < .001), with fibrosis stage (one-way ANOVA, p = .040), with adiponectin (Spearman's correlation, p = .033), and all three different CVD Risk scores were found. Finally, a strong negative correlation was detected between serum adiponectin and CVD Risk scores. CONCLUSIONS: In this study's cohort of MASLD patients, high MPV was associated with higher fibrosis stages and with increased estimated risk for CVD. Correlations of serum adiponectin to MPV and CVD risk scores support its implication as a cytokine-mediator that has to be further studied.
