Klebsiella Brain Abscess in Adults

Background: We analyzed the clinical manifestations and therapeutic outcomes of Klebsiella brain abscesses. Patients and Methods: The clinical data of 15 patients with Klebsiella brain abscesses, retrospectively collected over a 14-year period, were studied. Results: The 15 patients included 13 cases of Klebsiella pneumoniae infection and two cases of Klebsiella oxytoca. All but one case were community-acquired infections. Locations of all of these abscesses were supratentorial. 12 cases involved a single abscess, and three involved multiple abscesses. Gas formation was also found in two cases (13%). Common predisposing factors included metastatic spread, chronic otitis media and neurosurgical procedures. Among these 15 patients, 11 were treated surgically and four received antibiotics alone. In total, 11 patients survived and four died, with an overall mortality rate of 26.7%. Conclusion: The clinical presentations and therapeutic outcomes varied according to the different Klebsiella species. While debilitating diseases were common in K. pneumoniae infections, they were not common in K. oxytoca infection. And while metastatic septic abscess is a well-known, devastating complication of K. pneumoniae septicemia, usually seen as a brain abscess with a gas-forming appearance, all of these K. oxytoca infection had both otogenic infections and more favorable outcomes.

Brain abscess due to Klebsiella pneumoniae in a liver-transplanted child

Abstract: Brain abscesses are a rare, severe complication of orthotopic liver transplantation (OLT). They are almost exclusively due to fungi, Nocardia , or Toxoplasma , and usually occur within months of surgery. Here we report the case of an adolescent who developed a brain abscess due to Klebsiella pneumoniae 11.5 years after OLT. Fever was absent and laboratory parameters were not indicative of infectious disease, and therefore the diagnosis of a central nervous system neoplasm was considered. Subsequent magnetic resonance imaging and spectroscopy led to a diagnosis of a brain abscess, and to prompt appropriate antibiotic treatment. This case shows that K. pneumoniae may cause a brain abscess long after liver transplantation. The appearance of neurological symptoms should alert clinicians to consider a brain abscess even in the absence of overt clinical/laboratory signs of inflammation, which may be blunted by chronic immunosuppression.     

Liver abscess in patients with cirrhosis of the liver: a 12-year experience

Purpose. Liver abscess is rare in patients with cirrhosis of the liver. The aim of this retrospective study was to investigate the incidence, clinical presentation, causal pathogens, and outcome of liver abscess in cirrhotic patients. Methods. We collected 21 liver abscess specimens (from 14 male patients and 7 female patients; Child A: B: C, 4: 7: 10) from 22 731 admissions of 6450 cirrhotic patients, from 1986 through 1998. Results. The common clinical symptoms and signs included fever, chills, and abdominal tenderness. The major predisposing factors were biliary tract disease (52%) and diabetes mellitus (48%). The diagnosis rate with abdominal ultrasonography was 79%. Gram-negative aerobes were the predominant pathogens (Klebsiella pneumoniae, 66.7%; Escherichia coli, 23.8%), and occurred in 80% and 69% of blood and pus cultures, respectively, while 38% of cases showed polymicrobial pathogens. The location of the abscess was predominantly in the right lobe (71.4%), and 47.6% of patients had multiple abscesses. Six patients died (all with Child C cirrhosis). The overall mortality rate was 28.6% (6/21). Conclusions. The incidence of liver abscess in the cirrhotic patients was low, at 0.09% (21/22 731 admissions). The clinical presentations and pathogens were not different from those in noncirrhotic patients, except that in our cirrhotic patients, there was no significant difference in mortality between those with monomicrobial and those with polymicrobial abscess; nor was there a significant difference in mortality between those with single and those with multiple abscesses. The Child C patients were the high-risk group. Received: November 6, 2000 / Accepted: February 2, 2001     

An Unusual Case of Neonatal Brain Abscess Following Klebsiella pneumoniae Septicemia

A case of solitary brain abscess in a term neonate caused by Klebsiella pneumoniae is described: K. pneumoniae, although a common cause of neonatal septicemia, is rarely implicated as an etiological agent for cerebral abscess in this age-group. The interest of this case lies in the rarity of the causative organism and atypical features. In the absence of predisposing factors in the neonate, we suspect that the infection was transmitted vertically from the mother before or at the time of delivery since there was evidence of asymtpomatic urinary tract infection in the antenatal period.
