[Hemolytic-uremic syndrome complicating a long-term treatment with gemcitabine. Report of a case and review of the literature].

INTRODUCTION

Gemcitabine is a nucleoside analog used in solid tumors since 1987. The main side effect is myelosuppression. Acute renal failure with thrombotic microangiopathy has also been reported. We report a new case and suggest to screen for this complication.

EXEGESIS: A 71-year-old man with metastatic adenocarcinoma of the pancreas was treated with gemcitabine. He developed episodes of recurred haemolysis followed by haemolytic uremic syndrome. One single haemodialysis session was performed. No other known causes for haemolytic and uremic syndrome were found. Gemcitabine appears to be a new cause of thrombotic microangiopathy. It results from cumulative effects, arises preferentially when there is a renal dysfunction and diagnosis is often delayed. Treatment must be stopped.

CONCLUSION

We suggest that reticulocyte count, haptoglobin level and urinalysis could help the clinician to maintain high vigilance and to have a rapid diagnosis for this rare disorder.
