Multicenter Study
Additional fibrate treatment in UDCA-refractory PBC patients.
There is no proven treatment for ursodeoxycholic acid (UDCA)-refractory primary biliary cholangitis (PBC) other than obeticholic acid. Although fibrates have been reported to improve biochemical parameters, the long-term effects remain unclear. This study evaluated the effect of fibrate on clinical outcomes of UDCA-refractory PBC. ⋯ In patients with UDCA-refractory PBC, additional fibrate treatment is associated with a higher probability of ALP normalization and a lower risk of cirrhosis development and hepatic deterioration.

Intrahepatic cholestasis of pregnancy (ICP) is the most common liver disorder specific to pregnancy and presents with maternal pruritus, raised concentrations of serum bile acids and abnormal liver function tests. ICP is associated with increased rates of spontaneous and iatrogenic preterm labour, fetal hypoxia, meconium-stained amniotic fluid and intrauterine death. Some clinicians treat ICP with ursodeoxycholic acid (UDCA) to improve maternal pruritus and biochemical abnormalities. However, there are currently no data to support the use of UDCA to improve pregnancy outcome as none of the trials performed to date have been powered to address this question. ⋯ Current practice in the UK at the time of trial commencement for the treatment of ICP is inconsistent, with some units routinely prescribing UDCA, others prescribing very little and the remainder offering it variably. Our previous pilot trial of UDCA in women with ICP demonstrated that the trial would be feasible, and the research question remains active and unanswered. Results are highly likely to influence clinical practice, through direct management and impact on national and international guidelines.

primary biliary cholangitis (PBC) patients with a suboptimal response to ursodeoxycholic acid (UDCA) have a significantly worse survival rate. Fenofibrate has been shown to improve the short-term biochemical response in this group of patients. However, there is limited data available on the safety and efficacy of its long-term use, especially in patients with cirrhosis. Methods：in this retrospective cohort study, fenofibrate was given to PBC patients with a suboptimal response to at least 12 months of UDCA (13-15 mg/kg/d) therapy. Biochemistry data, GLOBE score and UK-PBC risk score at baseline and at different time points of treatment were compared. The safety profiles were also compared between cirrhotic and non-cirrhotic patient groups. Results：fenofibrate (200 mg/day) was given to 39 PBC patients with a suboptimal response to UDCA (15 cirrhotic and 24 non-cirrhotic patients). In the 26 patients who completed more than one year of combination therapy, the alkaline phosphatase (ALP) levels were 215 (185, 326) U/l, 122 (110, 202) U/l, 128 (106, 194) U/l, 124 (100, 181) U/l and 120 (82, 168) U/l, at baseline, three months, six months, 12 months and 24 months, respectively. All p values were < 0.01 when compared to baseline values. After two years of combination therapy, the UK-PBC risk score and GLOBE score did not significantly improve. The overall rates of adverse events were not significantly different between the cirrhotic and non-cirrhotic group. The elevation of liver enzymes was the most frequent side effect (n = 7), leading to a discontinuation in four patients. Furthermore, after two years of combination therapy, the serum creatinine levels and estimated glomerular filtration rates (eGFR) were significantly worse in both groups. ⋯ fenofibrate add-on therapy could improve ALP and γ-GT levels in both non-cirrhotic and cirrhotic PBC patients with a suboptimal response to UDCA. However, patients need to be monitored carefully for a potential liver injury and nephrotoxicity.

Pretreatment prediction of response to ursodeoxycholic acid in primary biliary cholangitis: development and validation of the UDCA Response Score.
Treatment guidelines recommend a stepwise approach to primary biliary cholangitis: all patients begin treatment with ursodeoxycholic acid (UDCA) monotherapy and those with an inadequate biochemical response after 12 months are subsequently considered for second-line therapies. However, as a result, patients at the highest risk can wait the longest for effective treatment. We determined whether UDCA response can be accurately predicted using pretreatment clinical parameters. ⋯ UK Medical Research Council and University of Milan-Bicocca.
