BACKGROUND/AIMS: Klebsiella pneumoniae (K. pneumoniae) has been emerging as the leading cause of liver abscess although the most common pathogen was Escherichia coli in the past. Our study was to clarify the significance of K. pneumoniae as a pathogen of pyogenic liver abscess. METHODS: We reviewed 157 cases of pyogenic liver abscess treated at Yeungnam University Hospital from 1996 to 2001. They were classified into two groups: K. pneumoniae group and non-K. pneumoniae group. The clinical presentations, characteristics of liver abscess, laboratory findings and the results of bacteriological studies were compared. RESULTS: The K. pneumoniae group included 60 (60.6%) cases among 99 cases with positive culture. We found higher incidence of alcoholics (45.0%) or diabetes millitus (35.0%) in K. pnemoniae group. Cryptogenic cause (61.7%) was the most frequent portal entry in K. pneumoniae liver abscess. On the other hand, in non-K. pneumoniae group, the cause of portal entry was usually the secondary (23.1%) following biliary disease (61.5%). Statistically, there was no significant difference in age, sex, symptom, characteristics of abscess, laboratory findings except total bilirubin level between the two groups. CONCLUSIONS: Liver abscess caused by K. pneumoniae has emerged as an important infectious disease with new clinical significance. When clinicians see pyogenic liver abscess in patients with alcoholics or diabetes millitus, K. pneumoniae should be considered first as a cause of liver abscess.

Emphysematous prostatic abscess is a very rare form of prostatitis. Emphysematous prostatic abscess due to Klebsiella pneumoniae may have a poor prognosis according to a few previous reports. We report a rare case of successfully treated emphysematous prostatic abscess with cystitis due to Klebsiella pneumoniae in a 50-yr-old man with 15-yr history of diabetes mellitus. The patient was referred to the emergency room of our hospital. The KUB film revealed gas shadows in the lower pelvic area suggestive of emphysematous cystitis or emphysematous prostatic abscess. The gas was mainly occupying the prostate and was also seen in the bladder on pelvic CT. The patient was successfully treated with long-term antibiotic use and additional percutaneous drainage of the abscess. Emphysematous prostatic abscess may be misdiagnosed as emphysematous cystitis due to the similar location of gas shadows on radiography. Computerized tomography and transrectal ultrasonography are helpful in making the diagnosis of emphysematous prostatic abscess. Appropriate use of effective antibiotics with drainage of pus is the best treatment. This case emphasizes the importance of timely and accurate diagnosis followed by appropriate treatment in emphysematous prostatic abscess in diabetic patients.

INTRODUCTIONKlebsiella pneumoniae septic arthritis and osteomyelitis, albeit uncommon in adults, are important sites of disseminated infection. Many case reports have shown K. pneumoniae as a cause of nosocomial transmitted septic arthritis in neonates and children. We report a rare case of an elderly patient with K. pneumoniae genitourinary infection spreading to the liver and other extra hepatic sites like the prostate and peripheral joint.

CLINICAL PICTUREThe patient presented with a short history of general malaise, fever and urinary symptoms, associated with an acute monoarthritis of the ankle. On admission, he was in septic shock. Investigations suggested an infective cause, as evidenced by raised total white cell count and pyuria. K. pneumoniae was cultured from both urine and ankle synovial fluid. Imaging confirmed multiple liver and prostatic abscesses, as well as osteomyelitis of the foot bones adjacent to the ankle.

TREATMENTTreatment in this case included surgical drainage of the affected joint and surrounding soft tissue structures, in addition to a 6-week course of systemic antibiotics.

OUTCOMEThe patient had good clinical response following treatment. In addition, we noted a normalisation of his laboratory parameters and resolution of the intraabdominal and pelvic abscesses.

CONCLUSIONThis case emphasises the importance of timely and accurate diagnosis followed by appropriate treatment in disseminated K. pneumoniae infection to prevent significant morbidity and mortality.

BACKGROUND/AIMS: Despite the improvement of personal and social hygiene, pyogenic liver abscess is still a common disease. We compared the incidence, infection route, underlying disease and major complications between two different local hospitals. METHODS: We reviewed the clinical data of 100 patients with pyogenic liver abscess who were treated at Seoul and Guri Hanyang University Hospital from 1999 to 2003. RESULTS: There were 64 males and 36 females in the study group; they were aged from 19 to 94 years with a mean of 56.5 years. Every year 19 to 23 pyogenic liver abscess patients were admitted to both hospitals. The most common organism isolated was Klebsiella pneumoniae in both local hospitals. In the Seoul hospital, diabetes (40.9%) was most common associated condition. In the Guri hospital, biliary tract disease or a history of hepatobiliary surgery (54.2%) was the most common associated condition. Catheter drainage and/or percutaneous needle aspiration were established as the standard treatment modality. CONCLUSIONS: In both regional hospitals, the incidence of pyogenic liver abscess did not decrease and Klebsiella pneumoniae was the most common organism. Diabetes and biliary tract disease, including, previous hepatobiliary surgery, were the most identifiable underlying disease.

BACKGROUND/AIMS: Klebsiella pneumoniae is emerging as the leading cause for liver abscess although the most common pathogen was Escherichia coli in the past. Patients with diabetes mellitus are more likely to have a pyogenic liver abscess with gas forming infection; a gas forming pyogenic liver abscess carries a higher morbidity and mortality than the non-gas forming group. This study was conducted to clarify the clinical presentation and prognostic factors for pyogenic liver abscess in diabetic patients compared with non-diabetic patients. METHODS: Medical records of 140 cases of patients treated for pyogenic liver abscess from January 1995 through January 2004 were reviewed retrospectively in detail. RESULTS: Among 140 cases of pyogenic liver abscess, underlying diabetes was present in 26.4% (37/140). The clinical presentation between the two groups was not significantly different. The most common organism for the pyogenic abscess was K. pneumoniae in both groups. A gas forming liver abscess was discovered in only the diabetic liver abscess group, 6 of 37 patients (16%). CONCLUSIONS: K. pneumoniae was the most common organism cultured in both diabetic and non-diabetic liver abscess. Gas forming liver abscess was more common in diabetic patients than non-diabetic patients. Diabetic patients had more complications than non-diabetic patients.

PURPOSE: The aim of this study was to review our experience with splenic abscesses, with respect to the relevant aspects of splenic abscesses and treatment outcomes. MATERIALS AND METHODS: We reviewed the cases of 18 patients who had splenic abscesses and who were treated at our hospital from November 1993 to December 2008. RESULTS: The most common symptom at presentation was abdominal pain in 12 patients (66.7%). The median duration from symptom onset until establishment of a diagnosis was 22 days. Streptococcus viridians was the most common pathogen (27.8%), follow by Klebsiella pneumoniae (22.2%). The mortality rate during the inpatient period and the previous 90 days was 16.6%. Three of four patients with Klebsiella pneumoniae showed a single abscess pocket. Four patients (22.2%) underwent percutaneous drainage, eight (44.5%) recieved antibiotic treatment only and six (33.3%) underwent splenectomy. CONCLUSION: There is no gold standard for treating splenic abscesses. Treatment should be customized for each patient.
