ABSTRACT

Background: Bile cast nephropathy (BCN) is an underdiagnosed renal complication associated with severe hyperbilirubinemia and is seen in patients with liver failure who have cholestatic complications. BCN-induced acute kidney injury (AKI) can require hemodialysis (HD), and the molecular adsorbent recirculating system (MARS) is a potentially useful therapeutic option. Case summary: A 57-year-old male presented with jaundice persisting for 1 month, with laboratory test results indicative of hyperbilirubinemia and AKI. Abdominal imaging and a biopsy confirmed biliary ductal dilation secondary to a pancreatic head mass. The patient had rapidly progressive renal failure and refractory hyperbilirubinemia, despite biliary decompression, and was started on HD. Subsequent therapy with albumin dialysis therapy using MARS was successful in reversing the AKI, the cessation of HD, and the restoration of native renal function. Conclusion: In the setting of BCN-induced AKI, timely initiation of MARS can provide a useful therapeutic strategy to reverse renal dysfunction and facilitate intrinsic renal recovery.

ABSTRACT

A 29-year-old man with chronic portal venous thrombosis resulting in portal biliopathy required stenting of his common bile duct (CBD) and underwent a transjugular intrahepatic portosystemic shunt (TIPS) procedure to decrease portal pressures. He later presented with abdominal pain in the setting of prolonged CBD stent placement and was found to have air within his TIPS stent with a fistula on endoscopic retrograde cholangiopancreatography between his fully covered CBD stent and bare metal TIPS stent. There was concern that further intervention would lead to an air embolus. We suggest that when multiple stents are indicated, stent selection with close monitoring is critical.

ABSTRACT

Encorafenib, a BRAF kinase inhibitor, in combination with binimetinib, a selective MEK inhibitor have known gastrointestinal adverse events; however, adverse colitis events have not been well studied. We report a case series of 4 patients with melanoma who developed inflammatory colitis after BRAF and MEK inhibition with encorafenib and binimetinib, respectively. In the setting of immune checkpoint inhibitor use, BRAF and MEK inhibitors can cause significant inflammatory colitis with endoscopic patterns of predominant right colon ulcerations. It can lead to significant morbidity and frequent interruption of cancer treatment. Early recognition and prompt intervention are critical to improving patient outcomes.
