MASLD
Brief summary
MASLD is with 25% the most prevalent liver disorder in Western society and is associated with overweight, obesity, metabolic syndrome (MetS), type 2 diabetes mellitus (T2DM) and cardiovascular diseases (CVD). MASLD is defined by a hepatic fat accumulation of more than 5% in the absence of classical causes of steatogenesis (e.g. alcohol and steatogenic drugs). It represents a broad spectrum of clinical entities from steatosis to advanced liver disease with hepatic failure. Most of the patients have simple steatosis, however in about 15-30% steatohepatitis (MASH) develops, which leads to an overall increase in morbidity and mortality due to the progression to fibrosis, cirrhosis and hepatocellular carcinoma (HCC). Patients with MASLD have no or few, mainly specific symptoms; and generally there is a silent progression of simple steatosis to NASH and in the end liver-related morbidity and mortality. Despite the clinical importance and the potential impact on healthcare resources, the majority of MASLD patients are currently not detected due to the lack of non-invasive methods to diagnose MASLD. To date, the prevalance of MASLD in Turkey among subjects at risk, and its relation to common comorbidities such as obesity, T2DM and CVD is not clear. Therefore, identification of MASLD patients in this cohort will give information on the prevalence in the group of uncomplicated overweight and obesity and those with concomitant cardiometabolic diseases. By early detecting these patients at risk to develop progressive liver diseases and extrahepatic manifestations, it will be possible to intervene and improve health. Within this context, this study aims to detect prevalence of MASLD among risk groups. Also, the risk factors related to MASLD etiology and progression, such as overweight, obesity, T2DM, CVD, diet and physical activity will be studied to have a better understanding of their presumed causal relationship with MASLD. This study is designed to study the prevalence of and risk factors associated with MASLD in adult populations at-risk of MASLD. Participants will undergo liver assessments via vibration controlled transient elastography. Lifestyle, demographic, and biochemical data will be collected.
