One hundred and one cases of Klebsiella bacteraemia from the National University Hospital, Singapore, were reviewed retrospectively. There were 54 (53.5%) males and 47 (46.5%) females. Mean (+/- SE) age was 54 (+/- 2.4) years. Overall mortality was 26%. Nosocomial infections accounted for 20%. Underlying diabetes mellitus and malignancy were present in 36 and 26% respectively. The source of the bacteraemia was not known in 33% of cases, 17% had liver abscess, 29% had urinary tract infections, 9% had pneumonia, 10% had an abscess separate from the liver, and 3% had biliary sepsis. Elevated alkaline phosphatase (> 100 U-1) was seen in all cases of liver abscess (sensitivity 100%, specificity 27%). Nonsurvivors had a significantly lower platelet count than survivors (104 +/- 25 x 10(9)/l vs. 176 +/- 15 x 10(9)/l, unpaired t-test P < 0.05), and a platelet count of less than 150 x 10(9)/l was associated with a significantly higher mortality (37% vs. 11%, chi 2 P < 0.01). Nosocomial infection was associated with 45% mortality, whereas community-acquired infection had a lower rate of 21%, this was not statistically significant. Seventy-eight per cent of these Klebsiella isolates were sensitive to gentamicin and cotrimoxazole, and 100% to imipenem.

Epidemiological data from 117 episodes of Klebsiella bacteraemia were compared with those from matched controls with Escherichia coli bacteraemia. Cases and controls were obtained from 20,631 blood cultures taken from patients in Hvidovre Hospital between 1990 and 1992. The data studied included: sex and age, risk factors, portal of entry, outcome, nosocomial acquisition and distribution within the hospital. The incidence of Klebsiella bacteraemia was 9.3/10,000 admissions (76% Klebsiella pneumoniae; 24% Klebsiella oxytoca). Patients with Klebsiella and E. coli bacteraemia had many common features, including a high incidence of neoplastic disease, biliary tract disease, and renal failure. Many had undergone surgery or received therapy with steroids, antacids or antibiotics. Klebsiella bacteraemia was more often found in males, in patients with hospital contact within the previous month, and polymicrobial infection. Logistic regression analysis showed that use of invasive plastic devices and diabetes were significantly associated with Klebsiella bacteraemia. The urinary tract was the commonest source, followed by the biliary tract; 27% of patients had no obvious focus of infection, and in many of these an invasive device may have been involved. Forty-five K-serotypes were found--the largest number being nine strains of type K3; only a few strains had acquired resistance characters to antimicrobial agents. There were no differences between community- and hospital-acquired strains; indicating that our hospital does not have a resident strain of Klebsiella.

Emphysematous pyelonephritis (EPN) is a rare condition that typically occurs in patients with diabetes mellitus, urinary tract obstruction, or immunosuppression such as solid organ transplant recipients. It has high mortality and frequently requires nephrectomy to achieve cure, although percutaneous drainage has been reported to be successful in some patients. We report a renal transplant recipient with underlying diabetes mellitus who developed iatrogenic EPN. The patient initially presented with dyspnea and was admitted for cardiac evaluation. There was no evidence of urinary tract infection at the time of admission. The patient developed high-grade fever 3 days after admission. Despite intravenous (IV) antibiotic therapy, the patient developed acute renal failure requiring hemodialysis. Studies revealed Klebsiella bacteremia and EPN. We believe that urinary tract infection was precipitated by urinary bladder catheterization performed on the day of admission. Despite 2 weeks of IV antibiotic therapy, infection persisted with progressive extension of gas into the perinephric space on repeat imaging. The patient underwent a transplant nephrectomy with subsequent clinical recovery. This case illustrates that antibiotics alone are often inadequate to cure and preserve renal function in EPN despite immediate therapy. Furthermore, this patient underscores the risk of serious infection precipitated by urinary bladder catheterization in immunocompromised patients.
