Obeticholic acid, a Farnesoid X Receptor Ligand, is being studied as a potential agent in nonalcoholic steatohepatitis (NASH). According to a recent study (Lancet 2015; 385: 956-65), patients assigned to receive obeticholic acid were more likely to have improved liver histology compared with placebo (50/110 [45%] compared with 23/109 [21%]). The obeticholic group had increase serum cholesterol and LDL cholesterol. This study looked at a subgroup of patients in the FLINT study who had undergone liver biopsies.
E Vilar-Gomez et al. Gastroenterol 2015; 149: 367-78. This prospective study of 293 patients with histologically-proven NASH were followed after undergoing lifestyle changes for 52 weeks. At week 52, 88 subjects (30%) had lost ≥5% of their weight. Degree of weight loss was independently associated with improvements in all NASH-related histologic parameters (steatohepatitis, NAS activity score, and fibrosis.
G Lassailly et al. Gastroenterol 2015; 149: 379-88. Between 1994-2013, 109 morbidly-obese patients with histologically-proven NASH underwent bariatric surgery. One year after surgery, NASH had disappeared from 85% of the patients.
P Angulo et al. Gastroenterol 2015; 149: 389-97. In this retrospective analysis of 619 patients with NAFLD (1979-2005), the authors noted that “fibrosis stage, but no other histologic features of steatohepatitis, were associated independently with long-term overall mortality, liver transplantation, and liver-related events.”
