Dear Editor:

Hepatitis C is an important health care problem, affecting 200 million people all over the world. About 1.8–8% of renal transplant patients are estimated to be infected with hepatitis C virus in developed countries.1 With the advent of direct-acting antivirals (DAAs) HCV treatment has evolved, allowing treatment with less systemic toxicity. As they were only recently approved for clinical use (in 2013), a lot of unanswered questions remain regarding their optimal clinical use, such as the minimum treatment duration. Their long-term effects are still unknown and the experience with these regimens on kidney transplant patients is still scarce2.

FS is a 44-year-old white male with a kidney transplant since January 2016. His maintenance immunosuppression was tacrolimus, mycophenolate mophetil and prednisolone. He developed stable chronic transplant dysfunction, with serum creatinine (sCr) of 1.8mg/dl one month after transplant. In his period on hemodialysis, from 2009 to 2015, he always showed negative serologic tests for hepatitis B, C and HIV. In August 2015 hepatitis C antibodies were detected during routine screening. Following the detection of hepatitis C infection, he was referred to the Hepatology Department. At the time of his first appointment, in November 2015, genotype 1b was identified and the viral load of HCV RNA was 1.6logIU/ml. He missed subsequent appointments and did not comply with the scheduled exams. He got a kidney transplant in February 2016. In August he returned to his Hepatology department to complete investigation. The viral load was at this time 6.1logcopy/ml. In January 2017 he began his treatment of eight weeks with ledispavir (90mg per day) plus sofosbuvir (400mg per day). Transient hepatic elastography revealed the value of 6.5kPa and he maintained normal asparate aminotransferase (21U/L) and alanine aminotransferase (19U/L). Tacrolimus trough level was around 5–5.5ng/mL.

On a routine blood scan 14 days later, acute kidney dysfunction was diagnosed – sCr 2.2mg/dl – and a low through level of tacrolimus was noted (3.8ng/ml). Consensus between Hepatology and Nephrology departments was to withhold treatment with DAAs. He was admitted to Nephrology ward and, as kidney dysfunction persisted, a kidney biopsy was performed on January 30th. The histopathology showed acute cellular rejection stage IA Banff with negative C4d. DSA (donor specific anti-HLA antibodies) were negative. He was treated with intravenous methylprednisolone bolus and anti-thymocyte globulin infusion, but maintained a stable sCr of 2.2mg/dl at the time of discharge. In his last kidney transplant routine appointment, sCr was 2.3mg/dl and tacrolimus trough levels were 6.7ng/ml.

HCV viral load determinations at 3 weeks after the beginning of treatment and sustained viral response at 24 weeks were negative. Hence, cure for hepatitis C was assumed with an ultra-short treatment time of 14 days. SVR is associated with greater survival and less likelihood of developing hepatic disease. Smith Palmer et al.3 in a systematic review report a cure rate of 98–99% four years after achieving SVR. Meanwhile, information over identical follow up in kidney transplant (KT) patients is still scarce. Fernandez et al.4 in 2016, reported one of the largest retrospective series (103 patients) on kidney transplant patients treated with DAAs. Treatment with sofosbuvir and ledispavir or sofosbuvir and daclatasvir in KT patients achieved a 98% rate of SVR. Although immunosuppression levels needed adjustment in 55% of patients there were only three acute rejection episodes that quickly resolved with therapy. Levels of sCr, glomerular filtration rate and proteinuria did not differ significantly from baseline.

In the immediate post-transplant period, the risk of acute rejection of the kidney transplant is not despisable. Post-KT population has an elevated risk of infectious, immunologic and neoplastic complications as well. KT patients represent a high level of financial investment and therefore require a larger effort in the management of their comorbidities.

Our case report shows cure of HCV infection only with 14 days of treatment. It seems to us to be the shortest treatment time with efficacy ever reported with ledispavir and sofosbuvir for treatment of HCV infection in a KT patient5,6. Short treatment times were also reported by Lau G et al.,7 in a phase 2 study on a Chinese population without cirrhosis, but we stress that a triple (not double) regimen was used, for 3 weeks. Sawinski et al.5 report a patient, black race, who achieved negative viral load after 29 days of treatment of ledispavir and sofosbuvir. This is, to date, the shortest response ever reported with these two agents. Meissner et al.8 report a case of successful treatment with sofosbuvir and ribavirin for 27 days. More experience is needed on the treatment of chronic hepatitis C in kidney transplant patients. The opportunity of using shorter treatment times, in an effective and more tolerable way, will be a great driver for investment and research in this area.
