P-111 FREQUENCY OF LIVER STEATOSIS AND FIBROSIS DETERMINED BY FIBROSCAN AND CAP IN A SCREENING PROGRAM

Abstract

Nonalcoholic fatty liver disease represents a worldwide public health problem, in Latin America a prevalence of around 30% is estimated, however in Peru we do not have large epidemiological studies about this. To evaluate the frequency of liver steatosis determined by CAP (Controlled Attenuation Parameter) and liver fibrosis by hepatic elastography in a population of patients who participated in a screening campaign. Descriptive and cross-sectional study. During the period September-December 2019, the ALEH Screening Fibroscan program was carried out in 4 reference hospitals in Lima and Callao. Patients were evaluated with a Fibroscan 530 device with M and XL probes. Those examinations that met the quality parameters were included for the study: 10 valid measurements, IQR <30% for liver stiffness, IQR <40 dB / m for CAP. The study population was people aged 18 and older who voluntarily attended the screening campaigns. 1978 patients were included, with an average age of 54.22 +/- 14.36 years, the distribution by sex was 1342 women (67.8%) and 636 men (32.2%). The distribution according to the degree of liver steatosis determined by CAP was S0: 1198 (60.6%), S1: 335 (16.9%), S2: 59 (3%), S3: 386 (19.5%). The distribution according to the degree of fibrosis was F0-1: 1662 (84%), F2: 97 (4.9%), F3: 98 (5%), F4: 121 (6.1%). In the studied population a frequency of hepatic steatosis of 39.4% and advanced hepatic fibrosis of 11.1% was found.
