PURPOSE: Direct-acting antivirals (DAAs) allow for successful transplantation of livers from hepatitis C nucleic acid test (NAT)-positive donors to negative recipients. However, limited data exist to support crushing DAAs in patients with multiple absorption concerns or significant drug interactions.
SUMMARY: Crushed sofosbuvir/velpatasvir has been successfully used in nontransplant patients with dysphagia, but data in transplant patients with absorption concerns are limited. A 31-year-old hepatitis C-negative female underwent liver transplantation from a hepatitis C NAT-positive donor. Her postoperative course was complicated by a mucormycosis infection, gastrointestinal bleed, and necrotizing pancreatitis requiring treatment with liposomal amphotericin B and pantoprazole 80 mg twice daily. Surgical interventions included an above-the-knee amputation and ileostomy. Hepatitis C treatment was initially delayed because of concern for reduced absorption with crushed DAA administration through the nasogastric (NG) tube, high ileostomy output, gastrointestinal bleed, pancreatitis, and a known drug interaction with pantoprazole. One month after transplantation, the patient's bilirubin level remained elevated and hepatitis C treatment was initiated with sofosbuvir/velpatasvir. Crushed sofosbuvir/velpatasvir was mixed with 30 mL of water and administered through the NG tube daily. Hepatitis C viral loads were obtained weekly during treatment to monitor efficacy. Although the patient died before evaluation of sustained virological response at 12 weeks, hepatitis C viral clearance was observed within 4 weeks of initiating treatment.
CONCLUSION: A liver transplant patient exhibited viral clearance of hepatitis C following administration of crushed sofosbuvir/velpatasvir in the setting of multiple absorption concerns.
