A 57-year-old man with ADPKD and a limited number of hepatic cysts (Fig. ) was admitted to the hospital because of fever (39.8 °C), right-sided flank pain, diarrhea, vomiting, and headache. Lanreotide injections (120 mg) were started 19 months earlier. At admission, serum CRP was elevated (131 mg/L) and liver enzymes were not elevated (AST 23 U/L, ALT 22 U/L, ALP 71 U/L, GGT 35 U/L). Leukocyturia was excluded. A chest radiograph and abdominal ultrasound were unremarkable. Blood cultures grew E. coli, whereas urine cultures were negative. Under the suspicion of hepatic cyst infection, the patient was hospitalized and treatment with ceftriaxone intravenously was initiated by the local physicians. At discharge, after 3 days, treatment was switched to oral ciprofloxacin for a total of 7 weeks. Recovery was uneventful.\nThe time between injection and development of cyst infection differed widely between patients (1–21 days). The number of days between injection and cyst infection for the individual cases was: 16 (case 1 episode 1) 21 (case 1 episode 2), 8 (case 2), 9 (case 3), 8 (case 4), 16 (case 5), 11 (case 6), and 1 (case 7). It was not documented whether microbiologists were involved in the management of liver cyst infections and whether antibiotic susceptibilities were performed.
A 54-year-old woman with ADPKD and PLD (Fig. ) presented with fever (39.6 °C) and cold shivers without abdominal pain, after having experienced abdominal complaints during a few weeks following each lanreotide injection. Lanreotide treatment (120 mg) was started 5 months earlier. At admission, serum CRP was 245 mg/L and some liver enzymes were elevated (ALT 62 U/L, ALP 119 U/L, and GGT 83 U/L). Leukocyturia was excluded with urine sediment analysis. Abdominal ultrasound showed no abnormalities, except for gallbladder sludge. Blood cultures grew E. coli. The patient was hospitalized for 3 days and treated by local physicians under the suspicion of hepatic cyst infection with cefuroxime intravenously. At discharge, treatment was switched to ciprofloxacin for another 11 days. Recovery was uneventful.
