Abstract

BackgroundAutosomal dominant polycystic kidney disease (ADPKD) is a hereditary disease characterized by the presence of renal cysts. Over time the expanding cysts lead to progressive renal failure. The use of tolvaptan, a V2-receptor antagonist, was recently approved in ADPKD patients. It was demonstrated that tolvaptan get slower decline in Kidney function compared with placebo. Idiosyncratic hepatic toxicity was described in patients receiving tolvaptan, with elevations in aminotransferases levels. We describe the first case reported in the literature in which hepatic toxicity is caused by the association of amoxicillin/clavulanic acid and tolvaptan.Case presentationA 41 years old woman with diagnosis of ADPKD had been in treatment with tolvaptan for 16 weeks when an elevation of liver enzyme levels was detected. She had taken autonomously amoxicillin/clavulanic acid (in doses of 825/175 mg twice a day for 7 days) about 5 weeks before.The timing of the event and the kind of hepatocellular injury could be attributed to the concomitance of medication of tolvaptan and amoxicillin/clavulanic acid.ConclusionWe highlight the need to careful monitor hepatic enzyme levels in order to recognize early hepatic side effects in ADPKD patients in treatment with tolvaptan and amoxicillin/clavulanic acid.

Highlights

Autosomal dominant polycystic kidney disease (ADPKD) is a hereditary disease characterized by the presence of renal cysts
ADPKD is the most common hereditary kidney disorder, accounting for about 10% of patients on dialysis or living with a renal transplant [1]. It is characterized by progressive development and growth of cysts causing progressive kidney enlargement, destruction of renal parenchyma till to end stage renal disease (ESRD) [2,3,4]
In the last decade, advanced knowledge in genetics and molecular pathobiology of ADPKD focused on some aberrant molecular pathways involved in the pathogenesis of the disease [2, 3] leading to controlled clinical trials aimed to delay its progression

Summary

Introduction

Autosomal dominant polycystic kidney disease (ADPKD) is a hereditary disease characterized by the presence of renal cysts. Conclusion: We highlight the need to careful monitor hepatic enzyme levels in order to recognize early hepatic side effects in ADPKD patients in treatment with tolvaptan and amoxicillin/clavulanic acid.
