[Infectious complications in autosomal dominant polycystic kidney disease].
Despite advances in the management of autosomal dominant polycystic kidney disease over the past two decades, infection of liver and kidney cysts remains a serious and potentially threatening complication. Kidney cyst infection is the most frequent complication. It is differentiated from hemorrhage by the clinical presentation (mainly the severity and duration of fever), C-reactive protein (CRP) and white blood cells levels, and the density of the suspected cyst on computed tomography. Liver cyst infection occurs more frequently in patients with large cysts volumes. It can be life threatening and has a tendency to recur. In both infections, the best radiological imaging technique is positron emission tomography after intravenous injection of [18F]-fluorodeoxyglucose combined with computed tomography. Treatment with a fluoroquinolone should be continued for 6 weeks. Cyst aspiration is necessary only when cysts are very large and/or when infection is resistant to antibiotic treatment. In patients who are candidates to kidney transplantation, a history of recurrent kidney cyst infection justifies pre-transplant nephrectomy, while a past history of recurrent liver cyst infection or angiocholitis leads to consider liver transplantation. Among extrarenal and extrahepatic complications of polycystic disease, colic diverticulosis is reported to be associated with increased risk of infection in patients on hemodialysis and after kidney transplantation. However, this observation needs to be confirmed.
