While multiple options exist for the treatment of pruritus in patients with primary biliary cholangitis (PBC), none have compelling evidence regarding their long-term efficacy and safety, according to a narrative review of literature by Hirsh D. Trivedi, MD, and associates.
There are four treatments commonly used for treating pruritus in PBC patients: bile acid–binding resins, rifampicin, opioid antagonists, and sertraline. In the cases of bile acid–binding resins, rifampicin, and opioid antagonists, significant side effects and a lack of proof of long-term efficacy prevent the treatments from standing out. Sertraline seems to have no significant side effects, but research is lacking, and further investigation is required.
Several experimental treatments for refractory pruritus also exist: These include phototherapy, plasmapheresis, albumin dialysis, nasobiliary drainage, ileal bile acid transporter–inhibitors, methotrexate and colchicine, and fibrates. In extreme cases, liver transplant can also be utilized to reduce pruritus symptoms.
“Our ongoing learning [about] this multifaceted symptom will hopefully lead to the development of more effective therapies and improve the quality of life for patients with primary biliary cholangitis,” the investigators concluded.
