Bacillus infection (first report with cisplatin andvinblastine): 2 case reports

Two men, who had received antineoplastic therapy,developed Bacillus infections and subsequently died.

The first man, aged 52 years, was hospitalised with feverand acute respiratory distress 10 days after his first cycle ofantineoplastic therapy comprising cisplatin, vinblastine andmethotrexate [dosages not stated] for bladder cancer.Physical examination revealed a lung disorder and a chestx-ray showed a localised area of alveolar consolidationaffecting the middle lobe. Blood tests showed thefollowing; bicytopenia, anaemia (5.1 g/dL), neutropenia(400 polynuclear neutrophils/mm3), plasma fibrinogen7.5 g/L, CRP 200 IU/L, severe hypoxaemia (50mm Hg atroom air), creatinine 270 µmol/L, plasmaurea 16.4 mmol/L. He was treated with ceftriaxone andciprofloxacin. During the following few hours, hedeveloped septic shock and was mechanically ventilated.He was administered catecholamines. Blood cultures werepositive within 24 hours and Gram-positive motile bacilliwere identified. The pathogen was subsequently identifiedas B. macerans. His condition deteriorated and he died fivedays after his admission.

The second man, who was aged 53 years and hadadenocarcinoma of the colon, was hospitalised followingpartial hepatectomy. He had been treated withantineoplastics [specific agents, dosages and duration oftherapy not stated] and had received his last cycle over amonth ago. He exhibited signs of septic shock with feverand was treated with catecholamines. Blood tests revealedthe following; WBC count 20 000/mm3, CRP 175 IU/L,plasma fibrinogen 0.45 g/L. His subclavicular centralvenous catheter, which had been placed more than6 months earlier, was removed and he was started onceftriaxone and ciprofloxacin. Blood cultures were positivein less than 24 hours and Gram-positive motile bacilli wereidentified. Culture of his central catheter revealed Gram-positive bacillus (103 CFU/mL). The pathogen wassubsequently identified as B. pumilus. His conditiondeteriorated, despite a change in antibacterials toamoxicillin-clavulanic acid and gentamicin, and he died5 days after admission.
