Advanced fibrosis associated with non-alcoholic steatohepatitis (NASH) in Spain: results of a Delphi study.

OBJECTIVE

To describe in detail the epidemiology, diagnosis, clinical management, treatment options, impact on quality of life and unmet needs of patients with advanced liver fibrosis (F3-F4) associated with non-alcoholic steatohepatitis (NASH) in Spain.

METHODOLOGY

Delphi study of two rounds of consultation rounds with 41 expert hepatologists from 16 autonomous communities to collect their experience in clinical practice.

RESULTS

The estimated prevalence of adult patients diagnosed with F3-F4 fibrosis associated with NASH in Spain is 0.019% (95% confidence interval [CI]: 0.019-0.020%). Approximately 7,588 adults with this condition are currently diagnosed and managed in the Digestive System Services of Spanish hospitals, and around 1,881 new patients are diagnosed each year. Management is multidisciplinary and includes the specialties of Digestive System, Endocrinology and Internal Medicine, considering the frequently associated metabolic comorbidities (obesity, type 2 diabetes mellitus or dysmetabolic iron overload). Despite a clear impact on quality of life, this it is not routinely evaluated in clinical practice. The most widely used non-invasive diagnostic techniques are transitional elastography and liver fibrosis index 4 (FIB-4). The absence of effective and safe treatments appears as the main unmet need for the management of these patients.

CONCLUSIONS

This study provides a representation of the current situation of patients diagnosed with F3-F4 fibrosis associated with NASH in Spain, increasing the evidence available and contributing to informed decision-making by professionals and the health system.
