No impact of steatotic liver disease on clinical outcomes in patients with essential thrombocythemia and polycythemia vera: A pilot study.

The presence of steatotic liver disease (SLD) is associated with an increased cardiovascular risk in the general population. Chronic myeloproliferative neoplasms (MPNs), essential thrombocythemia (ET) and polycythemia vera (PV), are characterized by clonal myeloproliferation, chronic inflammatory state, and increased cardiovascular morbidity and mortality. The aim of this single-center study was to analyze clinical associations and the potential prognostic impact of SLD in ET and PV patients. We retrospectively included 108 patients (64 ET and 44 PV); median age was 70.5 years (range 21-92), 68 (63 %) were females, and the median follow-up time was 69 months. Baseline SLD presence was defined ultrasonographically and was detected in 25 (23.1 %) patients. There were no associations of SLD with any of the clinical and laboratory patient characterictics. Also, baseline ultrasonographic presence of SLD did not have an impact on future thrombotic, bleeding and disease transformation risk, nor patient survival. None of the patients experienced signs of liver failure during the follow-up. In conclusion, the presence of SLD in ET and PV patients does not seem to have major clinical implications. Therefore, patients may be advised about the generally harmless nature of SLD when occurring in the MPN context.
